A cast-in-place concrete insulated wall and its construction method

Abstract

This invention provides a cast-in-place concrete built-in insulation wall and its construction method, solving the problems of existing wall insulation structures, which are mostly prefabricated solid slab structures with limited thickness and difficult-to-repair surface scratches or damage. The insulation core board structure of this invention uses multiple insulation boards assembled together, which not only adapts to the design requirements of different wall insulation layer thicknesses, but also allows for direct replacement of the outer insulation board when the outer layer is damaged during transportation and assembly, saving material costs. Furthermore, filling the insulation core board structure with concrete not only reduces the number of insulation boards required but also strengthens the structural strength, thereby enhancing the load-bearing and shear performance of the finished insulation wall. The intermittent concrete layers within the insulation core board structure provide a layered waterproofing function.

Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a cast-in-place concrete built-in insulation wall and its construction method. Background Technology

[0002] The CCW (Concrete Curtain Wall) building system is a type of external building insulation system, divided into cast-in-place concrete insulation curtain wall systems and post-installed concrete insulation curtain wall systems. The cast-in-place concrete curtain wall system is a system consisting of a concrete surface layer and insulation board materials, and it does not bear the load or action of the main structural structure. The concrete surface layer is constructed simultaneously with the main structural concrete, and the insulation board is fixed to the main structure using connectors.

[0003] Most current wall insulation structures are prefabricated solid panel structures, which have the following disadvantages when used: once the insulation board is prefabricated, its thickness is difficult to change. During transportation and construction assembly, it is difficult to repair scratches or even damage to the surface of the insulation board, affecting the insulation effect. Moreover, the cost of directly replacing the whole board is also high, which is not conducive to cost saving. Summary of the Invention

[0024] A construction method for a cast-in-place concrete built-in insulation wall includes the following steps: Step 1, prefabricate the insulation board, waterproof board type I, waterproof board type II, and steel mesh according to the design requirements of the construction drawings;

[0025] Step 2: Level the ground and place sleepers at intervals on the leveled ground to form an assembly surface;

[0026] Step 3: Place the waterproof membrane type I with the second connector facing up on the assembly surface;

[0027] Step 4: According to the thickness requirements of the insulation core board structure in the construction drawings, select the corresponding number of insulation boards. Select the first insulation board and hoist it above the waterproof board type I. Connect the first connector on the insulation board to the second connector on the waterproof board type I. Hoist the remaining insulation boards one by one and install them on the first insulation board layer by layer through the first connector and the second connector to obtain the insulation core board structure.

After the concrete has solidified and passed inspection, remove the formwork to complete the construction.

[0033] Advantages of this invention: The thermal insulation core board structure is assembled from multiple thermal insulation boards, which can not only adapt to the design requirements of different wall insulation layer thicknesses, but also, when the outer layer of the thermal insulation core board structure is damaged during transportation and assembly, the outer layer insulation board can be directly replaced, saving material costs.

[0034] Filling the core board structure with concrete not only reduces the number of insulation boards required but also strengthens the structural strength of the core board structure, thereby enhancing the load-bearing and shear performance of the finished insulated wall. Simultaneously, the intermittent concrete layers within the core board structure provide a layered waterproofing function, isolating the insulation boards layer by layer and further improving the structure's resistance to moisture and corrosion during use.

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] The waterproof board type II 4 is located on the right side of the heat-insulating core board structure, and a plurality of first connectors are fixedly provided on the left side of the waterproof board type II 4. The first connectors on the waterproof board type II 4 are detachably connected to the second connectors on the right side of the heat-insulating core board structure one by one. A third cavity 7 that is transparent up and down is formed between the waterproof board type II 4 and the heat-insulating core board structure; both the second cavity 6 and the third cavity 7 are filled with concrete 20.

[0048] Specifically, in this embodiment, the heat-insulating board includes two models: heat-insulating board type I 1 and heat-insulating board type II 2. As Figure 3 and Figure 4 shown, the first connector includes a first hook plate 101 fixedly provided on the right side of the heat-insulating board type I 1, a third hook plate 201 on the left side of the heat-insulating board type II 2, and a sixth hook plate 401 on the left side of the waterproof board type II 4.

[0050] As Figure 1 and Figure 2 shown, the heat-insulating core board structure, the waterproof board type I 3, and the waterproof board type II 4 are provided with tie bolts extending in the left-right direction. Specifically, the tie bolt includes a tie bolt rod 9 extending in the left-right direction. A spacer 10 and a first nut 11 are provided on the tie bolt rod 9. The spacer 10 is a frustum-shaped elastic pad, and the first nut 11 is used to squeeze the spacer 10 against the sides of the waterproof board type I 3 and the waterproof board type II 4 away from the heat-insulating core board structure.

[0051] As Figure 1 and Figure 2 shown, steel mesh 19 is provided on the outer sides of the waterproof board type I 3 and the waterproof board type II 4, and the tie bolts are detachably connected to the steel mesh 19. Specifically, as shown in Figure 5 shown, a sliding cylinder 13 is movably sleeved on the tie bolt rod 9. As shown in Figure 6As shown, the slide cylinder 13 has a first through hole 1301 for the pull screw 9 to pass through, and the slide cylinder 13 is located on the side of the first nut 11 away from the insulation core board structure.

[0052] A second nut 12 is provided on the right side of the slide cylinder 13, and a fourth nut 18 is provided on the left side of the slide cylinder 13. Both the second nut 12 and the fourth nut 18 are threadedly connected to the pull screw 9. The second nut 12 and the fourth nut 18 are used to restrict the left and right movement of the slide cylinder 13.

[0053] A fixed cylinder 14 is fixedly provided on the slide cylinder 13, and a second through hole 1401 is provided inside the fixed cylinder 14. A hook is detachably fixed on the slide cylinder 13, which is used to hook and fix the steel mesh 19.

[0054] Specifically, such as Figure 5 As shown, the hook assembly includes a hook rod 15 extending in the front-to-back direction and two third nuts 16. The hook rod 15 includes a lead rod extending in the front-to-back direction and a hook head fixed at one end of the lead rod. The hook head has a curvature greater than or equal to 180 degrees and is used to hook onto the vertical bars of the steel mesh 19. The hook rods 15 adjacent to each other are arranged opposite or facing each other. The lead rod passes through the second through hole 1401. The two third nuts 16 are spaced apart on the lead rod and located on the front and back sides of the fixed cylinder 14. The outer diameter of the third nuts 16 is larger than the diameter of the second through hole 1401. The third nuts 16 are threadedly connected to the lead rod.

[0055] To improve the stability of the fourth nut 18 in concrete, such as Figure 5 As shown, an anti-detachment plate 17 is fixedly provided on the right side of the fourth nut 18. The anti-detachment plate 17 includes a straight plate section and inclined plate sections fixed at the front and rear ends of the straight plate section. The other end of the inclined plate section away from the straight plate section extends inclinedly away from the fixed cylinder 14. The straight plate section is fixedly connected to the fourth nut 18, and the straight plate section is provided with a third through hole corresponding to the left and right screw holes of the fourth nut 18. The pull screw 9 passes through the third through hole and the fourth nut 18.

[0056] like Figure 1 As shown, the thermal insulation core board structure, waterproof board type I 3, waterproof board type II 4, steel mesh 19, and tie bolts are all located within the concrete 20, and the first cavity 5, the second cavity 6, and the third cavity 7 are all filled with concrete 20.

[0057] The insulation core board structure is assembled from multiple insulation boards of type I 1 and type II 2. This not only adapts to the design requirements of different wall insulation layer thicknesses, but also allows for direct replacement of the outer insulation board when the outer layer of the insulation core board structure is damaged during transportation and assembly, saving material costs.

[0058] Filling the core board structure with concrete 20 not only reduces the demand for insulation board materials, but also strengthens the structural strength of the core board structure, thereby enhancing the load and shear performance of the formed insulation wall.

[0059] A waterproof board is installed on the outside of the insulation core board structure to waterproof the structure. This prevents the insulation board from getting damp and corroding too quickly, while also enhancing the waterproof performance of the insulation wall and providing a dry and suitable indoor environment.

[0060] A construction method for cast-in-place concrete embedded insulation walls includes the following steps:

[0061] Step 1: Prefabricate the insulation board, waterproof board type I 3, waterproof board type II 4, and steel mesh 9 according to the design requirements of the construction drawings.

[0062] Step two: Level the ground and place sleepers at intervals on the leveled ground to form an assembly surface.

[0063] Step 3: Place the waterproof membrane type I 3 with the second connector facing up on the assembly surface.

[0064] Step 4: According to the thickness requirements of the insulation core board structure in the construction drawings, select the corresponding number of insulation boards. Select the first insulation board and hoist it above the waterproof board type I 3. Manually slide the first connector on the insulation board into the second connector on the waterproof board type I 3. Hoist the remaining insulation boards one by one and install them on the first insulation board layer by layer through the first connector and the second connector to obtain the insulation core board structure.

[0065] Step 5: Hoist the waterproof membrane type II 4 to the top of the insulation core board structure, and slide the first connector on the waterproof membrane type II 4 into the second connector on the top of the insulation core board structure.

[0066] Step 6: Pass the tie rod 9 through the waterproof board type II 4, the insulation core board structure, and the waterproof board type I 3 sequentially from top to bottom. By suspending the tie rod 9, erect the waterproof board type II 4, the insulation core board structure, and the waterproof board type I 3 and place them upright on the assembly construction surface. Install the pad 10 and the first nut 11 on the tie rod 9 to fix the tie rod 9 to the waterproof board type II 4, the insulation core board structure, and the waterproof board type I 3.

[0067] Step 7: Install the second nut 12, the slide cylinder 13 and the fourth nut 18 on the tie rod 9. Hoist the prefabricated steel mesh 19 to the left and right sides of the insulation core board structure, so that the end of the tie rod 9 passes through the mesh gap of the steel mesh 19. Adjust the left and right position of the slide cylinder 13 and install hooks on the slide cylinder 13 so that the hooks hook and fix the steel mesh 19.

[0068] Step 8: Transport the fixed steel mesh 19, waterproof type I 3, thermal insulation core board structure and waterproof type II 4 to the wall construction site, and install the template on the outside of the two steel meshes 19.

[0069] Step 9: Pour concrete 20 from above. The concrete 20 fills the gaps between the formwork, steel mesh 19, waterproof type I 3, insulation core board structure and waterproof type II 4. After the concrete 20 has solidified and passed the inspection, remove the formwork and the construction is completed.

[0070] Example 2: A cast-in-place concrete built-in insulation wall. In this example, the sliding cylinder 13 and hook are no longer provided. The tie rod 9 and the steel mesh 19 are tied together with wire. Other structures are the same as in Example 1.

[0071] Example 3: A cast-in-place concrete wall with built-in insulation. In this example, the first connector is a slide rail with a T-slot, and the second connector is a T-shaped plate or I-beam adapted to the slide rail. Other structures are the same as in Example 1.

[0072] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims and not by the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
