    金刚砂地坪耐污染及耐破损的施工方法

    2018-10-23 08:12:19 无锡盛发地坪科技有限公司 阅读

    传统的金刚砂环氧地坪在进行设备安装等多工种交叉作业操作时,会不可避免地造成污损,使金刚砂环氧地坪劣化速度加快,从而产生侵蚀、掉皮、滞水等缺陷,很难达到客户要求。下面笔者介绍一种创新金刚砂地坪耐污染及耐破损的施工方法,供相关工程人员参考。

    The traditional diamond floors will inevitably cause pollution when they are operated by equipment installation and other kinds of cross operation, which will accelerate the deterioration rate of the diamond floors, resulting in erosion, peeling, stagnant water and other defects, which are difficult to meet customer requirements. Below the author introduces an innovative diamond floor anti-pollution and anti-damage construction method, for the reference of relevant engineers. 1.工程概况

    1. project overview

    业主要求生产厂房全部按食品生产用洁净间的污染来控制地坪,所以本工程施工的核心是解决食品厂房超大面积地坪达到洁净厂房规范要求。

    Owners require the production plant to control the floor according to the pollution of the clean room for food production, so the core of this project construction is to solve the problem that the large area of the floor of the food plant meets the requirements of the clean workshop.

    2.几种金刚砂地坪面施工工艺的选择

    2. selection of construction technology for several kinds of emery floor

    2.1二次收光工艺

    2.1 two light harvesting process

    采用二次撒播金刚砂、圆盘机压实磨平、镘光机硬刀初凝前后压光到终凝前收光+密封固化剂和养护结合的施工方法。具有不亲水,外部光滑等优点。但是施工操作烦杂,需专业技术人员协作,需要熟练技术工人操作且养护密封费用大。

    The construction method of the combination of the second seeding emery, the compaction and grinding of the disc machine, the calendering of the hard knife of the calender before and after the initial setting, and the light before and after the final setting, the sealing and curing agent and the curing agent is adopted. It has the advantages of non hydrophilic and smooth external. However, the construction operation is complicated and requires the cooperation of professional and technical personnel, skilled workers and maintenance and sealing costs.

    2.2一次削光工艺

    2.2 one time polishing process

    采用一次撒播金刚砂、圆盘机压实磨平、镘光机硬刀初凝前后压光到终凝前收光、镘光机硬刀终凝前后削光密封、养护的施工方法,具有不亲水,外部光滑坚实的优点,但是需要熟练技术工人操作且,新浇砼面一次撒播需采取新措施,养护密封技术难度大、人工费用大。

    Adopting the construction method of one-time spreading emery, compacting and grinding of disc machine, pressing and polishing the hard knife before and after the first setting to the final setting, polishing and sealing and curing the hard knife before and after the final setting, it has the advantages of non-hydrophilic, smooth and solid exterior, but it needs skilled workers to operate and to take the new concrete surface one-time spreading. New measures, maintenance sealing technology is difficult, labor costs.

    2.3二次削光工艺

    2.3 two times glazing process

    采用二次撒播金刚砂、圆盘机压实磨平、镘光机硬刀初凝前后压光到终凝前收光、镘光机硬刀终凝前后削光密封和养护结合的施工办法。同样具有不亲水,外部光滑坚实的优点,但是养护密封技术难度大、人工费用大。

    The construction method of combination of polishing sealing and curing is adopted, which consists of twice spreading emery, compacting and grinding of disc machine, pressing and polishing of hard knife of calendering machine before and after initial solidification to final solidification, and polishing and sealing of hard knife of calendering machine before and after final solidification. Similarly, it has the advantages of non-hydrophilic, smooth and solid exterior, but the maintenance and sealing technology is difficult and labor costs are high.

    通过对金刚砂地坪的不同工艺进行实验对比分析后,,可以看出二次收光工艺造价高、施工难度大、不适合超大面积施工。而二次削光金刚砂地坪在施工操作和价格上更具有优势,为此我们选取此方案为最佳方案。

    By comparing and analyzing the different processes of diamond floor, it can be seen that the secondary lighting process has the advantages of high cost, difficult construction and unsuitable for super large area construction. Secondary polishing diamond floor has more advantages in construction operation and price, so we choose this scheme as the best one.

    3.具体施工策略

    3. specific construction strategy

    3.1采用掺高性能减水剂不掺粉煤灰配合比砼为了使钻面金刚砂地坪结构实体的坍落度损失值不大于2mm,使其抗压强度及耐磨强度符合设计要求,金刚砂地坪“采用掺高性能减水剂不掺粉煤灰配合比砼”来浇筑地坪结构实体,以提高钻面金刚砂地坪结构实体的抗压强度及耐磨强度要求。

    3. The requirements for compressive strength and wear resistance of diamond faced floor structures are improved.

    3.1.1确定只掺高性能减水剂砼施工重点。通过集中讨论,明确了对地坪结构质量有重大影响的三个关键施工控制要素:一是混凝土运输时间,能否连同浇筑和技术间歇的全部时间不超过混凝土的初凝时间,是确保地坪结构混凝土振捣密实的关键。二是混凝土坍落度,对大面积地坪混凝土的摊铺和输送有重要意义。三是混凝土浇筑的最后一道工序—振捣,是决定地坪结构成型好坏的关键。

    3.1.1 determines the key points of concrete construction with high performance superplasticizer only. Through centralized discussion, three key construction control factors which have a significant impact on the quality of floor structure are defined. First, the key to ensure the compactness of floor structure concrete is whether the concrete transportation time, together with the whole time of pouring and technical intermission, does not exceed the initial setting time of concrete. The two is the slump of concrete, which is of great significance to the spreading and transportation of large area concrete. The three is the final process of concrete pouring - vibration, which is the key to determine the quality of the floor structure.

    3.1.2相关工程人员查阅大量同类工程混凝土运输时间参数,结合工程实际,通过实地测算,初步确定了三种混凝土运输时间参数。

    3.1.2 Relevant engineers consult a large number of similar projects concrete transport time parameters, combined with the actual project, through on-the-spot measurement and calculation, preliminary determined three concrete transport time parameters.

    3.1.3通过现场浇筑试验发现,1小时的运输时间可选择的混凝土搅拌站少,没有质量优势,2小时的运输时间每天浇筑砼量受较大限制,不利于超大面积施工。而采取1.5小时的运输时间,则大部分可选到质量好的搅拌站,形成的稳定的混凝土质量,且20个工人效率最高。因此选取1.5小时和20人参数。

    3.1.3 Through the field pouring test, it is found that there are few concrete mixing stations to choose for one hour transportation time, and there is no quality advantage. The daily pouring amount of concrete for two hours transportation time is greatly limited, which is not conducive to the construction of super large area. When the transportation time is 1.5 hours, most of them can be selected to the mixing station with good quality to form a stable concrete quality, and 20 workers are the most efficient. So select 1.5 hours and 20 person parameters.

    3.1.4混凝土坍落度参数是超大面积地坪浇筑连续推移范围能够满足振捣密实的重要参数,需初步确定混凝土坍落度参数。

    3.1.4 The slump parameter of concrete is an important parameter that can satisfy the compactness of vibrating compaction in the continuous moving range of super-large area floor pouring. It is necessary to determine the slump parameter of concrete preliminarily.

    3.1.5混凝土坍落度参数是超大面积地坪浇筑连续推移范围能够满足振捣密实的重要参数,采用出料口坍落度10~12cm,摊铺推移坡度约为30°,推移范围约为2m,通过综合分析现场试验效果,我们对装料斗坍落度17~18cm的第2种方案参数再采取对砼泵送管进行保温、降温措施。

    The slump parameter of 3.1.5 concrete is an important parameter that can satisfy the compactness of vibrating tamping in the continuous moving range of super-large area floor. The slump of outlet is 10-12 cm, the slope of spreading is about 30 degrees and the moving range is about 2 m. Through comprehensive analysis of field test results, the second scheme of slump of loading hopper is 17-18 cm. Parameters are adopted for insulation and cooling of concrete pumping pipes.

    按最终选定的混凝土运输时间参数进行浇筑后,结果显示:混凝土运输时间为1.5小时浇筑的混凝土,全部摊铺振捣后,上人刚好有脚印,达到初凝。

    After pouring according to the final selected parameters of concrete transportation time, the results show that: the concrete poured in 1.5 hours of concrete transportation time, all the paving vibration, the superintendent just has footprints, to reach the initial setting.

    3.2金刚砂地坪结构实体钢筋安装

    3.2 erection of reinforced concrete floor structures

    为了面筋为多面钻石漏斗形找坡,基准沉降差为±1.5㎜以内。金刚砂地坪结构实体钢筋安装“钢筋面为多点面钻石漏斗形找坡状”。

    In order to find gluten for a multifaceted diamond funnel, the base settlement difference is within 1.5. The steel bar of the diamond structure is a "multi point diamond funnel shaped slope".

    3.2.1为了确保保护层保持一致,丌型马凳和作为加设在各节点直圆钢马凳的直径大小,必须经过验算。

    3.2.1 In order to ensure that the protective layer is consistent, the diameters of the open horse stool and the straight round steel horse stool installed at each node must be checked.

    3.2.2采用经验算符合要求的φ16圆钢点焊固定面筋在精确测设的平面标高及坐标位置,多个圆钢马凳精确定位的面筋就形成了一个漏斗集水范围为多面钻石状漏斗形,在圆钢马凳上进行标识。

    3.2.2 By experientially calculating the plane elevation and coordinate position of the fixed gluten of the spot welded circular steel which meets the requirement, the gluten accurately positioned by several round steel horse stools forms a multi-faceted diamond-shaped funnel, which is marked on the round steel horse stool.

    3.2.3操作工人可把导轨准确地安装在预先定好的位置。

    The 3.2.3 operator can accurately install the guide rail in a predetermined position.

    3.2.4导轨安装完成后,结果测量复核校正加固后正式使用,且在使用过程中动态测量检查,确保导轨的精确度满足要求。

    3.2.4 After the installation of the guideway is completed, the results are measured, checked, corrected and strengthened, and the dynamic measurement is checked during the use to ensure that the accuracy of the guideway meets the requirements.

    3.3满足坡度要求和对平整度控制后进行大面积施工

    3.3 meet slope requirements and large area construction after flatness control.

    为了地坪表面光滑结实;呈钻面多点面漏斗形找坡0.5%;地坪平整度控制在2m靠尺±2㎜以内,“地坪面采用多点面钻石状漏斗找坡”满足坡度要求和对平整度控制后进行大面积施工。

    In order to make the surface of the floor smooth and firm, the multi-point funnel-shaped slope search on the drilling face is 0.5%; the flatness of the floor is controlled within 2 m ruler (+2), "the multi-point diamond funnel slope search on the ground surface" is used to meet the slope requirements and carry out large-area construction after the flatness control.

    3.3.1为了确保超大面积金刚砂地坪施工的质量保持稳定,对生产厂房找坡采取多点面钻石状漏斗形的施工方法,以确保地坪面的坡向正确和平面标高控制导轨能直线安装并制定工艺流程来指导现场操作。

    3.3.1 In order to ensure the stability of the construction quality of the super large area diamond floor, a multi-point diamond funnel-shaped construction method is adopted for the slope finding of the production plant to ensure the correct slope direction of the floor and the plane elevation control guide rail can be installed in a straight line and the process flow is formulated to guide the site operation.

    3.3.2在超大面积金刚砂地坪地漏集水范围,利用cad软件计算机绘出多面钻石状漏斗形交接折线平面投影位置,预先将坡度标高分配到各节点,然后用全站仪在垫层面测设出实际位置线,减小超大面积上多台镘光机操作对坡向的折损。

    3.3. Damage.

    3.3.3在地漏中心半径250mm范围内的漏斗尖,采用木板制作成方盒围起后浇,地漏外边沿比方盒边沿低20mm,并做好堵孔等保护。

    3.3.3 The funnel tip with a radius of 250 mm in the center of the floor drain is enclosed by a square box made of wood and then poured. The outer edge of the floor drain is 20 mm lower than the edge of the square box, and the hole plugging and other protections are well done.

    3.3.4为确保多面钻石状漏斗成型,地坪结构面筋节点下布设一根ф16圆钢直马凳,按该节点标高下35mm为面筋顶面,确保保护层的统一。

    3.3.4 In order to ensure the formation of multi-faceted diamond funnel, a 16 steel straight horse-stool is arranged under the gluten joint of the floor structure, and the top surface of the gluten is 35mm below the joint elevation, so as to ensure the unification of the protective layer.

    3.3.5按节点拉线安装导轨,测量员用激光扫平仪动态测设导轨控制标高,然后均匀浇筑结构混凝土,待垫层混凝土稍收水后,具有初凝强度时,启动抹平机慢速磨搓、压浆。然后用尺杆刮平,使混凝土浆面保持平整、均匀。

    3.3.5 Install the guide rail according to the pulling line of the node. The surveyor uses the laser scanner to dynamically measure the control elevation of the guide rail, and then pours the structural concrete evenly. When the cushion concrete is slightly watered and has the initial setting strength, start the plastering machine to grind and grout slowly. Then the scraper is leveled with the ruler bar to make the concrete slurry surface smooth and even.

    3.3.6基层混凝土初凝至五成干时,进行第一次撒料。首先撒规定用量的2/3,待得金刚砂在混凝土表面吸水变暗后,用圆盘磨光机压实搓毛,经一段时间后再将剩余1/3的金刚砂依样撒布,撒布方向与第一次撒布方向垂直,撒布后立即抹平、镘光,并重复镘光机作业至少两次。镘光机作业时应纵横向交错进行,均匀有序,防止材料聚集。边角处分别用木、铁抹子人工处理。确保地坪表面平整度允许偏差值为每2m允许偏差2㎜以内。效果检查:通过以上措施,确保地坪面多面钻石状漏斗形找坡的坡度,保证了地坪结构面筋顶面预留35mm厚保护层,使金刚砂面层与结构结合得更加牢固,且通过测量用激光扫平仪动态测设导轨控制标高,有效保证了多面钻石状的成型。

    3.3.6 when the concrete is initially condensed to 50% dry, the first batch of material is dispersed. Firstly, sprinkle 2/3 of the prescribed amount of diamond on the concrete surface, then compact and rub with a disc polisher. After a period of time, spread the remaining 1/3 of the diamond according to the sample. Spread the direction perpendicular to the first direction, immediately wipe and calender, and repeat the calender operation at least twice. When the trolling machine is operated, it should be crisscross and interlaced in order to prevent material aggregation. The edges and corners are manually treated with wood and iron trowel. The allowable deviation of floor surface evenness is guaranteed to be within 2 2m of allowable deviation. Effect checking: Through the above measures, the gradient of multi-faceted diamond funnel-shaped slope searching is ensured, and a 35 mm thick protective layer is reserved on the top of gluten of floor structure, which makes the combination of diamond surface layer and structure more firmly. The control elevation of multi-faceted diamond is effectively ensured by dynamically measuring the guide rail with laser leveler. Molding.

    4.1.1 has mastered the construction process and control points of the diamond flooring.

    通过本实施,在今后类似工程施工中,为防止金刚砂面层与结构的结合,进而影响金刚砂地坪施工质量,应该注意地坪结构钢筋面保护层厚度不宜大于35mm。金刚砂地坪结构钢筋面筋为多面钻石状漏斗形找坡,有利于保护层的均匀一致,可保证保护层的偏差控制在规范允许范围内。

    Through this implementation, in the future construction of similar projects, in order to prevent the combination of diamond surface layer and structure, and then affect the construction quality of diamond floor, it should be noted that the thickness of reinforcement surface protective layer of floor structure should not be greater than 35mm. The reinforcement gluten of diamond floor structure is diamond funnel-shaped, which is beneficial to the uniformity of the protective layer and ensures that the deviation of the protective layer is within the allowable range of the code.
