Description

模块化强约束组合剪力墙及其建造方法Modular strong restraint combined shear wall and construction method thereof 技术领域Technical field
本发明涉及一种模块化强约束组合剪力墙及其建造方法，属于装配式建筑技术领域。The invention relates to a modularized strong restraint combined shear wall and a construction method thereof, and belongs to the technical field of prefabricated buildings.
背景技术Background technique
剪力墙又称抗风墙、抗震墙或构造墙。房子或构筑物中首要接受风荷载或地震效果引起的水平荷载和竖向荷载(重力)的墙体，防止构造剪切(受剪)损坏。又称抗震墙，通常用受力筋混凝土做成。Shear walls are also called wind-resistant walls, earthquake-resistant walls or structural walls. In the house or structure, the wall which mainly accepts the horizontal load and vertical load (gravity) caused by wind load or seismic effect, to prevent structural shear (shear) damage. Also known as seismic wall, usually made of reinforced concrete.
现有的现浇受力筋混凝土剪力墙主要有以下缺点：The existing cast-in-place reinforced concrete shear walls mainly have the following shortcomings:
1、混凝土强度离散性大：受混凝土运输时间，施工人员浇筑、振捣等操作过程的影响，剪力墙子的混凝土离散性强度较大。1. Large dispersion of concrete strength: Affected by the concrete transportation time, construction personnel pouring, vibrating and other operations, the concrete dispersion strength of the shear wall is relatively large.
2、施工繁琐复杂：现浇的受力筋凝土剪力墙，需要在剪力墙四周支模板，模板竖立起后需要支撑和紧固构件进行固定，浇筑完成后需等待一定的龄期方能拆模，施工繁琐且周期长。2. The construction is cumbersome and complicated: the cast-in-place reinforced concrete shear wall needs to support the formwork around the shear wall. After the formwork is erected, support and fastening members are required to fix it. After the pouring is completed, it is necessary to wait for a certain age. The mold can be removed, the construction is cumbersome and the cycle is long.
3、模板的周转需要一定的时间，为了加快工期，需要施工单位同时准备多套模板，增加造价。3. The turnover of the formwork takes a certain amount of time. In order to speed up the construction period, the construction unit needs to prepare multiple sets of formwork at the same time, which increases the cost.
4、模板在反复支模和拆模的过程中容易变形或损坏，影响剪力墙成型的质量。4. The template is easily deformed or damaged in the process of repeated mold support and mold removal, which affects the quality of the shear wall forming.
5、对施工人员技术要求高，剪力墙子浇筑的质量与模板制作和施工浇筑的质量紧密相关。主要体现在:5. The technical requirements for construction personnel are high, and the quality of shear wall pouring is closely related to the quality of formwork and construction. mainly reflects in:
1)剪力墙子的垂直度不易保证：由于模板支模的精度不高，且在反复使用下模板容易变形，混凝土浇筑中对剪力墙模板产生侧压力，斜向支撑不牢等一系列原因都容易造成剪力墙垂直度发生偏移。1) The verticality of the shear wall is not easy to guarantee: because the precision of the formwork support is not high, and the formwork is easy to deform under repeated use, the shear wall formwork will be laterally stressed during concrete pouring, and the diagonal support is not strong. The reasons are likely to cause the verticality of the shear wall to shift.
2)当支撑和紧固构件不稳固时，容易产生“爆模”现象，后期需要对爆模处的混凝土进行踢打。2) When the supporting and fastening members are unstable, it is easy to produce the phenomenon of "explosive mold", and the concrete at the exploded mold needs to be kicked in the later stage.
3)剪力墙底易产生“烂根”：剪力墙子底部表面不平，剪力墙子模板底部与剪力墙子基础表面缝隙过大，剪力墙底混凝土振捣时发生严重漏浆，砂石多水泥浆少，出现混凝土剪力墙“烂根”。所以，模板与基础表面的缝隙应用木片或水泥袋填堵，防止漏浆，施工麻烦。3) The bottom of the shear wall is prone to "rotten roots": the bottom surface of the shear wall is not flat, the gap between the bottom of the shear wall formwork and the foundation surface of the shear wall is too large, and the concrete at the bottom of the shear wall leaks seriously when vibrating. , There is more sand and gravel and less cement paste, and “rotten roots” of concrete shear walls appear. Therefore, the gap between the template and the foundation surface should be filled with wood chips or cement bags to prevent slurry leakage and troublesome construction.
4)易露筋：模板四角拼缝未堵好，或模板支撑不牢固，振捣时，混凝土浇筑振捣时从拼缝处漏浆；受力筋的垫块移位，或垫块太少，甚至漏放，受力筋紧贴模板致使拆模后露筋。4) Easy to show ribs: the four corners of the formwork are not properly plugged, or the formwork support is not strong, when vibrating, the concrete leaks from the joints when the concrete is poured and vibrated; the pads of the reinforced ribs are shifted, or the pads are too few , Even leaking, the stressed ribs are close to the template, causing the ribs to be exposed after demoulding.
5)混凝土蜂窝麻面，缺棱掉角。主要产生原因是模板表面粗糙或清理不干净；浇筑混凝土前木板未湿或湿润不够；养护不好；混凝土振捣不密实；过早拆模，受外力撞击或保护不好，棱角被碰掉。5) Concrete honeycomb pitted surface with missing edges and corners. The main reason is that the surface of the formwork is rough or not cleaned; the wood board is not wet or not wet enough before pouring the concrete; the maintenance is not good; the concrete is not compacted by vibration; the mold is removed prematurely, and the edges and corners are knocked off due to external impact or poor protection.
6、剪力墙的水平受力筋和暗柱箍筋需要单独的进行加工绑扎。施工现场需要一片场地对水平受力筋和暗柱箍筋进行加工，受力筋工采用受力筋加工机器对受力筋进行弯曲加工成封闭环箍，运输到剪力墙子处，根据图纸的箍筋间距进行定位固定和绑扎，施工繁琐。6. The horizontal force bars and hidden column stirrups of the shear wall need to be processed and tied separately. The construction site needs a site to process the horizontal force bars and hidden column stirrups. The force bar workers use the force bar processing machine to bend the force bars into closed loops and transport them to the shear wall. According to the drawings The spacing of stirrups is fixed and tied, and the construction is cumbersome.
7、剪力墙子水平筋为间隔布置，对于混凝土的无约束效果，不能大幅提高抗压、抗剪承载和剪力墙延性。7. The horizontal bars of the shear wall are arranged at intervals, which has no restraint effect on the concrete and cannot greatly improve the compression resistance, the shear bearing capacity and the ductility of the shear wall.
现有的装配式受力筋混凝土剪力墙主要有以下缺点：The existing prefabricated reinforced concrete shear walls mainly have the following shortcomings:
1、自重较大，运输吊装复杂。1. Heavy weight and complicated transportation and hoisting.
2、目前受力筋接头采用灌浆套筒连接，施工时，受力筋不易对齐，连接质量不易保证，灌浆不易密实。2. At present, the joints of the stressed bars are connected by grouting sleeves. During construction, the stressed bars are not easy to align, the connection quality is not easy to guarantee, and the grouting is not easy to compact.
8、剪力墙子水平筋为间隔布置，对于混凝土无约束效果，不能大幅提高抗压、抗剪承载和剪力墙延性。8. The horizontal bars of the shear wall are arranged at intervals, which have no restraint effect on the concrete, and cannot greatly improve the compression resistance, the shear bearing capacity and the ductility of the shear wall.
发明内容Summary of the invention

本发明还涉及一种模块化强约束组合剪力墙的建造方法，包括如下步骤：The invention also relates to a method for constructing a modularized strong restraint combined shear wall, which includes the following steps:
S1、根据剪力墙的受力需求，计算出使用受力筋的数量；S1, according to the force requirements of the shear wall, calculate the number of force bars used;
S2、根据剪力墙通孔的位置信息及受力筋在通孔内的布置信息，将若干受力筋的底端固定在建筑物或构筑物上；S2, according to the position information of the through-holes of the shear wall and the arrangement information of the force-receiving bars in the through-holes, fix the bottom ends of several force-receiving bars to the building or structure;
S3、将若干墙体模块依次从若干受力筋的顶端穿入并逐层向上堆叠，水平相邻墙体模块之间通过第一企口错位结构相互接合，竖向相邻墙体模块之间通过第二企口错位结构相互接合，若干受力筋分别位于若干通孔内；S3. Pass several wall modules in turn from the tops of the stress bars and stack them up layer by layer. The horizontally adjacent wall modules are connected to each other through the first tongue-and-groove dislocation structure, and the vertical adjacent wall modules are connected to each other. The second tongue-and-groove dislocation structure is mutually joined, and a plurality of stress ribs are respectively located in a plurality of through holes;
S4、从墙体顶部向若干通孔内填充混凝土将若干受力筋及若干墙体模块紧固为一体即可。S4. Fill concrete from the top of the wall to a number of through holes to fasten a number of reinforcement bars and a number of wall modules into one body.
通过将剪力墙进行模块化分割，只需在现场进行拼装即可，将传统的扎钢筋网，侧面支模、模板固定等步骤进行了简化，大大缩短了施工周期，提高了工作效率。堆叠完成后向通孔中填充混凝土，可保证所有受力筋和剪力墙体模块紧固为一体，提高了整体强度。同时只需要墙体模块拼装即可成模，模块重量轻，减化了剪力墙建造工序，节约了人力成本。By modularizing the shear wall, it only needs to be assembled on site. The steps of traditional steel meshing, side support and formwork fixing are simplified, which greatly shortens the construction period and improves work efficiency. After the stacking is completed, the through holes are filled with concrete, which can ensure that all the force bars and the shear wall modules are fastened together, which improves the overall strength. At the same time, it can be formed by assembling the wall modules. The weight of the modules is light, which reduces the shear wall construction process and saves labor costs.
进一步，在步骤S3中，建造相邻两排墙体时，上排墙体的墙体模块之间构成的接合缝与下排墙体的墙体模块之间构成的接合缝错位设置。该步骤的设置，可通过将一块墙体模块对半分割，然后将一半墙体模块用于端部拼接，其后拼接的剪力墙体模块构成的接合缝与不同排构成的接合缝完全错位。也可在工厂直接预制出半块墙体模块，该半块墙体模块仅是在长度上与其他模块有所区别，其他结构均与其他墙体模块一致。通过接合缝错位设置，可提高剪力墙整体受力性能，提高接缝处的抗剪承载力。Further, in step S3, when two adjacent rows of walls are constructed, the joints formed between the wall modules of the upper row of walls and the joints formed between the wall modules of the lower row of walls are arranged in a staggered manner. The setting of this step can be done by dividing a wall module in half, and then using half of the wall module for end splicing. The joints formed by the shear wall modules after the splicing are completely misaligned with the joints formed by different rows. . A half wall module can also be prefabricated directly in the factory. The half wall module is only different from other modules in length, and other structures are consistent with other wall modules. By displacing the joints, the overall force-bearing performance of the shear wall can be improved, and the shear bearing capacity of the joints can be improved.
