Description

Technical Field

[0001] This utility model relates to the field of prefabricated exterior wall structure technology, and in particular to a new material exterior wall structure that can improve the connection strength of the wall. Background Technology

[0002] With the accelerating pace of industrialization in the construction industry, prefabricated modular buildings are increasingly widely used in residential and public buildings due to their significant advantages, such as high construction efficiency, minimal on-site wet work, easy quality control, and energy conservation and environmental protection. In the prefabricated modular building system, prefabricated exterior walls utilize factory prefabrication as the core process. Innovative materials, distinct from traditional ordinary concrete and cement mortar, are used in the substrate, functional layers, and connecting auxiliary materials of the components, resulting in prefabricated exterior wall components with superior performance. For example, lightweight aggregate concrete (using lightweight aggregates such as expanded clay and volcanic slag instead of crushed stone) reduces the component's self-weight while ensuring foundation strength; fiber-reinforced cementitious composite materials (FRCC, such as those incorporating carbon fiber and basalt fiber) improve the crack resistance and impact resistance of the substrate. Currently, the vertical joints between adjacent precast new material exterior wall panels are usually sealed with sealant for waterproofing. This method can only solve the basic sealing and waterproofing needs and cannot provide a strengthening connection between adjacent precast new material exterior wall panels. As a result, when horizontal loads (such as wind loads and seismic forces) are transferred to the exterior wall through the floor slab, each wall panel is under independent stress, which seriously affects the overall rigidity and seismic performance of the building. Utility Model Content

[0003] This utility model relates to a new material exterior wall structure that can improve the connection strength of the wall. It solves the problem that the vertical joints of existing adjacent prefabricated new material exterior wall panels lack reinforcement structures, causing each wall panel to be under independent stress, which seriously affects the overall rigidity and seismic performance of the building.

[0004] The new material exterior wall structure provided by this utility model, which can improve the connection strength of the wall, includes: a prefabricated new material exterior wall panel, wherein a rectangular insertion groove is uniformly formed on the right end face of the prefabricated new material exterior wall panel, and a grouting through hole A communicating with the rectangular insertion groove is formed on the right side of the upper end face of the prefabricated new material exterior wall panel; a second connecting plate is provided at the left end of the prefabricated new material exterior wall panel, and a first connecting steel plate is installed on the left side of the second connecting plate; a rectangular insertion block is uniformly fixedly connected to the left end face of the first connecting steel plate, and a grouting through hole B is formed on the upper end face of the rectangular insertion block; the rectangular insertion block is inserted into the rectangular insertion groove; and a reinforcing connection component is provided inside the grouting through hole A and the grouting through hole B.

[0005] Furthermore, a fixing bolt is movably inserted into the first connecting steel plate; and an avoidance groove is provided on the right end face of the prefabricated new material exterior wall panel.

[0006] Furthermore, when two adjacent prefabricated new material exterior wall panels are in the assembly state, grouting through hole A and grouting through hole B are on the same axis, and the fixing bolts are located in an adjacent clearance groove.

[0007] Furthermore, the depth of the clearance groove is equal to the thickness of the hexagonal swivel block on the fixing bolt.

[0008] Furthermore, the reinforcing connection assembly includes a circular fixing plate, reinforcing connecting bars, and concrete. The upper surface of the circular fixing plate is welded with reinforcing connecting bars in a ring array. The circular fixing plate is located inside the grouting through hole A. The reinforcing connecting bars are inserted into the grouting through holes A and B. The concrete is poured inside the grouting through holes A and B, and the concrete is located outside the reinforcing connecting bars.

[0009] Furthermore, the second connecting plate is welded with embedded steel bars, and a threaded cylinder is fixedly connected to the right end face of the second connecting plate. Both the embedded steel bars and the threaded cylinder are embedded inside the left side of the prefabricated new material exterior wall panel.

[0010] Furthermore, when the first connecting steel plate and the second connecting plate are in the installation state, the fixing bolts are threadedly connected to the threaded cylinder.

[0011] This utility model provides a new material exterior wall structure that can improve the connection strength of walls, and has the following beneficial effects: 1. This utility model improves the connection strength of the wall by using a combination of rectangular insertion slots, rectangular insertion blocks, grouting through holes A and B, and reinforcing connection components. In specific assembly, the rectangular insertion blocks are inserted into the corresponding rectangular insertion slots, and then the circular fixing plate is placed inside the grouting through hole A, so that the reinforcing steel bars are inserted into the grouting through holes A and B. Then, concrete is poured into the grouting through holes A and B. After solidification, a high-strength connection is formed between adjacent precast new material exterior wall panels, so that they can work together to bear the force, thereby significantly improving the overall rigidity and seismic performance of the building.

[0012] 2. This utility model achieves the detachable function of the edge components through the cooperative design of the first connecting steel plate, the second connecting plate, the fixing bolts and the threaded cylinder. When the left side of the prefabricated new material exterior wall panel does not need to be assembled with the prefabricated new material exterior wall panel, the fixing bolts can be removed, and the first connecting steel plate and the rectangular plug block can be removed, thereby ensuring the flatness of the wall end face, facilitating subsequent beautification construction, and improving the flexibility of the application of this new material exterior wall structure.

[0013] 3. Through the design of the clearance groove, when two adjacent prefabricated new material exterior wall panels are fixedly assembled together, the hexagonal rotating block on the fixing bolt can be completely accommodated in the clearance groove. Since the depth of the clearance groove is equal to the thickness of the hexagonal rotating block of the fixing bolt, it can effectively constrain the fixing bolt and prevent it from rotating and loosening under vibration environment, thereby further improving the firmness and reliability of the connection between adjacent prefabricated new material exterior wall panels.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Example 1:

[0017] Please refer to Figures 1 to 5This utility model proposes a new material exterior wall structure that can improve the connection strength of the wall, including: a prefabricated new material exterior wall panel 1, the right end face of which is uniformly provided with rectangular insertion grooves 101, and the upper end face of the prefabricated new material exterior wall panel 1 is provided with a grouting through hole A102 communicating with the rectangular insertion grooves 101; a second connecting plate 4 is provided at the left end of the prefabricated new material exterior wall panel 1, and a first connecting steel plate 2 is installed on the left side of the second connecting plate 4; a rectangular insertion block 201 is uniformly fixedly connected to the left end face of the first connecting steel plate 2, and a grouting through hole B202 is provided on the upper end face of the rectangular insertion block 201; the rectangular insertion block 201... 1. It is inserted into the rectangular insertion slot 101; the grouting through hole A102 and the grouting through hole B202 are provided with a reinforcing connection component 3; the reinforcing connection component 3 includes a circular fixing plate 301, a reinforcing connecting steel bar 302 and concrete 303. The upper end face of the circular fixing plate 301 is welded with the reinforcing connecting steel bar 302 in a ring array. The circular fixing plate 301 is located inside the grouting through hole A102. The reinforcing connecting steel bar 302 is inserted into the grouting through hole A102 and the grouting through hole B202. The concrete 303 is poured inside the grouting through hole A102 and the grouting through hole B202, and the concrete 303 is located outside the reinforcing connecting steel bar 302.

[0018] This utility model improves the connection strength of the wall by adopting the above-mentioned technical solution. Specifically, during assembly, after the rectangular plug-in block 201 is inserted into the corresponding rectangular plug-in slot 101, the circular fixing plate 301 is placed inside the grouting through hole A102, so that the reinforcing connecting steel bar 302 is inserted into the grouting through hole A102 and the grouting through hole B202. Then, concrete 303 is poured into the grouting through hole A102 and the grouting through hole B202. After it solidifies, a high-strength connection can be formed between the adjacent prefabricated new material exterior wall panels 1, so that they can work together to bear the force, thereby improving the overall rigidity and seismic performance of the building.

[0019] A fixing bolt 203 is movably inserted into the first connecting steel plate 2; a clearance groove 103 is provided on the right end face of the precast new material exterior wall panel 1; when two adjacent precast new material exterior wall panels 1 are in the assembly state, the grouting through hole A102 and the grouting through hole B202 are on the same axis, and the fixing bolt 203 is located in an adjacent clearance groove 103; the depth of the clearance groove 103 is equal to the thickness of the hexagonal rotating block on the fixing bolt 203.

[0020] By adopting the above-mentioned technical solution, this utility model can effectively constrain the fixing bolt 203, prevent it from rotating and loosening under vibration, and further improve the firmness and reliability of the connection between adjacent prefabricated new material exterior wall panels 1. Example 2:

[0021] Based on Example 1, such as Figure 3 and Figure 5As shown, a pre-embedded steel bar 401 is welded on the second connecting plate 4, and a threaded cylinder 402 is fixedly connected to the right end face of the second connecting plate 4. Both the pre-embedded steel bar 401 and the threaded cylinder 402 are pre-embedded inside the left side of the prefabricated new material exterior wall panel 1. When the first connecting steel plate 2 and the second connecting plate 4 are in the installation state, the fixing bolt 203 is threadedly connected to the threaded cylinder 402.

[0022] By adopting the above-mentioned technical solution, this utility model realizes the detachable function of the edge components. Specifically, when the prefabricated new material exterior wall panel 1 does not need to be assembled on the left side, the fixing bolt 203 can be removed, and the first connecting steel plate 2 and rectangular plug block 201 can be removed, thereby ensuring the flatness of the wall end face, facilitating subsequent beautification construction, and improving the flexibility of the application of this new material exterior wall structure.

[0023] During assembly, the rectangular insertion block 201 on the first connecting steel plate 2 on the right side is inserted into the rectangular insertion slot 101 opened on the precast new material exterior wall panel 1 on the left side, so that the grouting through hole A102 and the grouting through hole B202 are on the same axis. Then, the circular fixing plate 301 is placed inside the grouting through hole A102, so that the reinforcing connecting steel bar 302 is inserted into the grouting through hole A102 and the grouting through hole B202. Subsequently, concrete 303 is poured from top to bottom into the grouting through hole A102 and the grouting through hole B202, so that the concrete 303 is located outside the reinforcing connecting steel bar 302. After the poured concrete 303 solidifies, the two adjacent precast new material exterior wall panels 1 are effectively reinforced and connected, avoiding the independent stress state of each precast new material exterior wall panel 1, which greatly improves the overall rigidity and seismic performance of the building.

[0024] When it is no longer necessary to assemble another prefabricated new material exterior wall panel 1 on the left side, the fixing bolt 203 on the left side can be loosened and removed with a tool. Then, the first connecting steel plate 2 and the rectangular plug block 201 on the left side can be removed from the corresponding second connecting plate 4. This ensures that the left side of the prefabricated new material exterior wall panel 1 has good flatness, which facilitates subsequent beautification construction and improves the flexibility of the application of this new material exterior wall structure.

[0025] When two adjacent prefabricated new material exterior wall panels 1 are fixedly assembled together, the hexagonal swivel block on the fixing bolt 203 will be located in an adjacent clearance groove 103. Since the depth of the clearance groove 103 is equal to the thickness of the hexagonal swivel block on the fixing bolt 203, the fixing bolt 203 can effectively prevent loosening inside the clearance groove 103, which further improves the firmness of the two adjacent prefabricated new material exterior wall panels 1 after they are fixedly assembled together.

[0026] The installation, connection, or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structure, model, and coefficient indicators of all components are their own technologies. As long as they can achieve their beneficial effects, they can be implemented.

[0027] The technical solution of this utility model is not limited to the scope of the embodiments of this utility model. All technical contents not described in detail in this utility model are known technologies.
