Description

Technical Field

[0001] The invention relates to the technical field of building wall materials, and in particular to an assembled core column polystyrene module, a combined module concrete pouring wall and a construction method. Background Art

[0002] The two insulation modules are connected by a connecting bridge to form a cavity. After laying steel bars in the cavity in both directions, concrete is poured to form a shear wall structure. Then a protective layer is applied to the outside of the insulation module to form a load-bearing insulation composite wall. Insulation modules are usually made of organic insulation materials such as EPS. In order to meet the safety and fire protection requirements of buildings, the protective layer needs to reach a certain thickness. For example, the current national standard "Code for Fire Protection Design of Buildings" GB50016 requires that the thickness of the fire protection layer must reach 50mm. The protective layer is usually formed by applying cement mortar on the outside of the insulation layer. When applying cement mortar on the vertical surface, the thickness of the application cannot be too thick at one time. It often takes 5-6 times to meet the requirements, and there is also the problem of easy cracking.

[0003] In order to solve the problems existing in the above-mentioned prior art, the patent document with application number 201720492420.5 discloses "a combined cavity EPS module". One of its characteristics is that the cavity module is composed of an outer panel, an inner panel and a connecting core rib. After the cavity module is assembled, steel bars are arranged in both horizontal and vertical directions in the cavity, and concrete is poured to form a shear wall structure; its second characteristic is that fixed inserts are arranged on the inner and outer panels, and the protective plates are fixed to the fixed inserts by connecting nails to form a protective layer outside the cavity module. The protective layer of this technical solution is fixed to the outside of the insulation layer by connecting nails, which effectively reduces wet operations on the construction site and is conducive to increasing the construction speed. However, the above two technical solutions still have the following technical problems:

[0004] 1. The cavity module forms a concrete shear wall structure, which uses a large amount of steel bars and concrete. However, for low-rise house walls or frame filling walls, the bearing capacity advantage of this concrete shear wall structure is not fully utilized, but will cause material waste and cost increase.

[0005] 2. The longitudinal and transverse bidirectional steel bars in the cavity module need to be tied in layers at the construction site, which not only consumes a large amount of steel bars, but also has high labor intensity and low production efficiency.

[0006] 3. The cavity module is integrally poured with concrete, which consumes a large amount of concrete, is labor-intensive, and increases construction costs.

[0007] 4. Due to the limited anti-deformation rigidity of the cavity module itself, it is necessary to add anti-deformation formwork support on both sides of the cavity module when pouring concrete. The construction process is complicated, the workload is large, and the construction cost is increased. Since the outer side of the wall needs to be plastered and finished at the construction site, scaffolding needs to be set up on the outer side of the building's exterior wall to cooperate with the construction, which has a low safety production rate and increases the construction cost.

[0115] Other components and connection relationships are the same as those of the ninth embodiment.

[0116] Specific implementation method 13: Combination Figure 1 and Figure 8 This embodiment is a wall structure system formed by combining the cavity module and the core column module. It is suitable for the construction of houses in villages and towns. The core column module and the cavity module have the same tongue and groove on the top, bottom, left and right sides, and have the same positioning card convex tenon and groove. The sizes and various positions of the two modules can be completely matched.

[0117] Due to its own design, the core column module can reduce the amount of concrete used by 30% compared with the cavity module, thereby reducing the construction cost; since the amount of concrete poured is reduced, the lateral pressure of the poured concrete is also reduced, so there is no mold expansion; at the same time, the wall heat transfer coefficient is increased from the original 0.25W / (㎡·K) to the current 0.15W / (㎡·K), and the thermal insulation performance is further improved, which is more conducive to the realization of dual carbon.

[0118] The installation method of the cavity module is to first implant the vertical steel bars → the cavity module passes through the steel bar combination → install the horizontal steel bars after each layer of modules is installed.

[0119] The installation method of the core column module is to first set the steel bar placeholder hole → place the module → place the vertical steel bar of the core column module. The lower part of the vertical steel bar of the core column module is placed in the vertical steel bar reserved hole, and the upper part is tied and fixed with the horizontal steel bar of the cavity module at the conversion part to position the steel bar during pouring.

[0120] Compared with the above two methods, the core column module is easy to install and construct, the construction speed is fast, and the amount of steel bars used is greatly reduced.

[0121] When cavity modules are used to build low-rise houses in villages and towns, a large amount of concrete is used, and their structural capacity is not fully utilized, which is a waste of material. With the use of core column modules, their structural capacity can be fully utilized, and the cost can be reduced to the maximum extent. In this application, the cavity modules are used in: the ±0.00 part of the wall, the 1 / 2 floor height part of the wall, the transition part between the wall and the floor, the basement wall and the wall above the window and the 600mm position on the left and right. The core column modules can be used in the rest of the parts.

[0122] Cavity modules are used at the ±0.00 position of the wall, the 1 / 2 storey height position of the wall, and the transition position between the wall and the floor to reduce the structural slenderness ratio and increase stability. Cavity modules are used in the basement wall to meet the requirements of the backfill soil on the lateral pressure of the basement wall. Cavity modules are used on the wall above the window and at 600mm on both sides to form an excess on the window top to meet the structural requirements.

[0123] Other components and connection relationships are the same as those of the ninth embodiment.

[0124] Specific implementation method 14: Combination Figures 1 to 14 , this embodiment is a modular combined wall construction method, comprising the following steps:

[0125] Step 1: pouring the foundation, setting vertical steel bars 14 in the foundation concrete;

[0126] Step 2: Install multiple layers of cavity polystyrene modules 11, the cavity polystyrene modules 11 pass through the vertical steel bars 14, after each layer of cavity polystyrene modules 11 is installed, install the cavity module horizontal steel bars 13 along the horizontal direction, tie the vertical steel bars 14 with the adjacent horizontal steel bars 13, and pour the cavity wall unit concrete;

[0127] Placement piles are set in the cavity wall unit concrete 19, and the placement piles are taken out when the concrete is finally set, forming a structural hole steel bar reserved hole 16, which is staggered with the steel bar reserved hole 15 of the same group on the foundation in the vertical direction;

[0128] Step 3: first install the multi-layer core column polystyrene module 12, then place the vertical steel bars 14 in the structural hole steel bar reserved holes 16, the structural holes on the core column polystyrene module 12 pass through the vertical steel bars 14 group, and pour the core column wall unit concrete;

[0129] Placement piles are arranged in the concrete 19 of the cavity wall unit, and the placement piles are taken out when the concrete is finally set, so as to form the structural hole steel bar reserved holes 16, which are staggered with the structural hole steel bar reserved holes 16 of the same group in the adjacent cavity wall unit in the vertical direction;

[0130] Step 4: Repeat steps 2 and 3 to install cavity wall units and core column wall units on each floor. If the wall does not have a basement structure, perform step 3 first and then step 2.
