Description

Technical Field

[0001] The invention belongs to the technical field of building wall structures and relates to a cast-in-situ sandwich insulation shear wall structure for an assembled high-rise residential building. Background Art

[0002] At present, most high-rise residential buildings adopt concrete shear wall structures. With the increasing requirements for thermal insulation, basically all high-rise buildings adopt thermal insulation measures. Among them, the thin plastering system of high-rise residential exterior walls has been used in China for many years, which has produced good economic and social benefits. However, the insulation layer adopts polystyrene foam board insulation material, which has poor fire resistance and serious fire hazards, and cannot achieve the same lifespan as the exterior wall. Therefore, the integrated insulation structure technology system has been vigorously promoted. At present, there are many integrated insulation structures on the market, most of which are sandwich insulation structures. The insulation board is located on the outer layer of the concrete structure layer, and there is a cast-in-place concrete slab at least 50 mm thick on the outside of the insulation board. The inner and outer layers of concrete are connected together by oblique or straight bars penetrating the insulation layer. The positioning and fixation of the insulation board of the current integrated insulation structure system is unreliable, resulting in the displacement of the insulation board during concrete pouring, and the cold bridge of the tie pieces penetrating the insulation board is serious, which greatly reduces the insulation effect. In addition, the thickness of the concrete protective layer outside the insulation layer is generally 50-60 mm, which is relatively thin. It is difficult to insert the vibrating rod into the concrete, making pouring difficult and easily causing pouring defects. In addition, the current integrated insulation structure wall structure concrete formwork construction is cumbersome, and the formwork construction progress is low, resulting in low wall surface accuracy and the need for plastering and leveling. In addition, the formwork of the concrete shear wall does not meet the requirements of assembly, and a lot of on-site cutting is required, resulting in serious waste. Based on the above problems, a new wall casting model structure is urgently needed. Summary of the invention

[0048] The insulation board 2, the first template 1 and the insulation board 2 are arranged in sequence;

[0049] The second template 3, the first template 1, the insulation board 2 and the second template 3 are arranged in sequence;

[0050] The anchor 4 is used to connect the first template 1, the insulation board 2 and the second template 3.

[0051] In the present embodiment, an assembled high-rise residential cast-in-place sandwich insulation shear wall structure is disclosed. On the outermost side of the cast-in-place concrete shear wall formwork structure are modular special first formwork 1 and second formwork 3. The two layers of special formwork are tied together by special tie pieces 4 that penetrate the insulation board 2 to form two cavities. The insulation board 2 and the second formwork 3 form a concrete protective layer cavity that accommodates a crack-resistant steel wire mesh 5 and concrete. The insulation board 2 and the first formwork 1 form a concrete structure cavity 8 that accommodates structural steel bars 6 and concrete, thus forming a sandwich insulation shear wall formwork structure. Compared with the prior art, the modular special formwork has uniform force and precise and reliable clamping grooves. After pouring concrete, the wall is very straight and the wall thickness is also precise, which can achieve flatness without plastering, improves the accuracy of pouring, and solves the problem of low wall pouring accuracy.

[0052] Further, the anchor 4 comprises:

[0053] A tie rod 41, which is used to connect the first template 1, the insulation board 2 and the second template 3;

[0054] The connecting member 42 is arranged on the tie rod 41 and is used to fix the positions of the first template 1, the insulation board 2 and the second template 3.

[0055] In this embodiment, the first formwork 1, the insulation board 2 and the second formwork 3 are connected and fixed in position by an anchor 4. The anchor 4 is composed of a tie rod 41 and a connecting member 42. The connecting member 42 is installed on the tie rod 41 and the first formwork 1, the insulation board 2 and the second formwork 3. The connecting member 42 fixes the relative position of the first formwork 1, the insulation board 2 and the second formwork 3 along the tie rod 41, determines the size of the space between the first formwork 1, the insulation board 2 and the second formwork 3, and the connecting member 42 is installed on the tie rod 41. The anchor 4 plays a role in supporting the shear wall model structure.

[0056] Furthermore, it also includes:

[0057] Steel mesh 5, which is arranged on the tie rod 41;

[0058] Structural steel bars 6, which are arranged on the tie rods 41;

[0059] A protective cavity 7 is formed between the first template 1 and the insulation board 2 for accommodating the wire mesh 5 and concrete;

[0060] A structural cavity 8 is formed between the second formwork 3 and the insulation board 2 for accommodating structural steel bars 6 and concrete.

[0061] In this embodiment, two layers of special formwork are tied together by special tie pieces 4 that penetrate the insulation board 2 to form two cavities. A protective cavity 7 is formed between the first formwork 1 and the insulation board 2, which contains a wire mesh 5 hung on the tie rod 41. A structural cavity 8 is formed between the second formwork 3 and the insulation board 2, which contains structural steel bars 6 hung on the tie rod 41. When concrete is poured into the two spaces, the concrete, the wire mesh 5 and the structural steel bars 6 form a concrete reinforced structure. The wire mesh 5 and the structural steel bars 6 act as reinforcing bars, thereby improving the strength of the wall structure.

[0062] Furthermore, it also includes:

[0063] A bearing member 9, the bearing member 9 is arranged on the tie rod 41 and is located in the structural cavity 8, and the structural reinforcement 6 is arranged on the bearing member 9;

[0067] In this embodiment, a bearing member 9 is also installed on the tie rod 41. The bearing member 9 is stronger than the tie rod 41. The structural steel bar 6 is arranged on the bearing member 9. The bearing member 9 improves the stability of the position of the structural steel bar 6 in the structural cavity 8. Even if it is impacted by concrete, it will not fall or tilt, thereby improving the stability and safety of the wall structure; the tie rod 41 is divided into a bending portion 411 and a straight rod portion 412. The straight rod portion 412 is connected in series to the entire formwork. The wire mesh 5 is hung on the bending portion 411 to ensure the positioning accuracy of the wire mesh and make the protective layer more stable and reliable.

[0068] Furthermore, the first template 1, the second template 3 and the insulation board 2 are all provided with:

[0069] The slot 10, the connecting member 42 is disposed in the slot 10;

The plug plate 421 is inserted into the slot 10 to fix it. The baffle 422 is perpendicular to the plug plate 421. The distance between the baffles 422 is the thickness of the first template 1, the insulation board 2 and the second template 3 respectively. In this way, the baffle 422 limits the specific positions of the first template 1, the insulation board 2 and the second template 3, and no position deviation will occur due to the impact of concrete.

[0074] Further, the bearing member 9 comprises:

[0075] A bearing plate 91, wherein the bearing plate 91 is disposed on the tie rod 41;

[0076] The load-bearing claw 92 is arranged on the load-bearing plate 91 , and the structural steel bar 6 is clamped on the load-bearing claw 92 .

[0077] In this embodiment, the bearing member 9 installed on the tie rod 41 is composed of a bearing plate 91 and a bearing claw 92. The bearing plate 91 is installed on the tie rod 41. When the concrete is poured, the bearing claw 92 ensures that the structural steel bar 6 will not change its position due to the impact of the concrete, so that the position of the structural steel bar 6 is accurate, and the structural strength of the wall is improved.

[0078] Further, the insulation board 2 is provided with:

[0079] The plug-in boss 21 is located at one end of the insulation board 2;

[0080] The plugging groove 22 is located at the other end of the insulation board 2 , the plugging boss 21 corresponds to the plugging groove 22 , and the plugging boss 21 is inserted into the plugging groove 22 of the adjacent insulation board 2 .

[0081] In this embodiment, the insulation board 2 is designed with an insertion boss 21 and an insertion groove 22. When the insulation board is installed, the insulation board is connected more tightly and reliably, the insertion is firm, and the insulation board is raised layer by layer. The operation is simple and firm, which improves the engineering efficiency.

[0082] Furthermore, the insulation board 2 is also provided with:

[0083] A clearance groove 23, which is arranged at one end of the insulation board 2 close to the protection cavity 7;

[0084] The compensation boss 24 is arranged on the end of the insulation board 2 opposite to the yielding groove 23 .

[0085] In this embodiment, the insulation board 2 used is a molded polystyrene board, and a clearance groove 23 is arranged on the insulation board 2. The clearance groove 23 is close to one end of the protective cavity 7. The clearance groove 23 is vertically arranged. The protective cavity 7 between the clearance groove 23 and the first template 1 is used to accommodate the insertion of the vibration rod. The vibration rod promotes the full pouring of concrete and will not cause air holes in the wall. There is a corresponding compensation boss 24 protruding on the inner side of the clearance groove 23 of the insulation board 2, which is used to compensate for the thinning of the insulation board 2 caused by the sinking of the insulation layer. While ensuring the insulation thickness, the strength of the insulation board 2 is also improved.
