Description

Technical Field

[0001] This invention relates to the field of building technology, and in particular to a lightweight prefabricated wall structure system. Background Technology

[0002] Currently, in prefabricated monolithic concrete structures, the most common wall-to-wall connection method is sleeve grouting connection. While sleeve grouting connection has seen rapid development, its relatively short history means that issues such as grout leakage and rebar eccentricity frequently occur at the connection between the sleeve and the embedded rebar due to factors like sleeve manufacturing precision and improper operation, resulting in substandard grouting quality. Furthermore, sleeve grouting connections are concealed works with complex structures, making quality inspection and assurance difficult. Therefore, the existing "equivalent to cast-in-place" technical system cannot fully leverage the advantages of prefabricated structures, resulting in unsatisfactory construction quality, efficiency, cost, and energy-saving and environmental protection effects. There is an urgent need to develop a safe, reliable, green, and efficient new prefabricated structural system. Summary of the Invention

[0045] 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.

[0046] Example 1: A lightweight prefabricated wall structure system, such as Figure 1 As shown, it includes a straight precast wall 1 and a corner precast wall 2. The straight precast wall 1 and the corner precast wall 2 can be spliced ​​together. A connection and installation area is formed between the straight precast wall 1 and the corner precast wall 2.

[0047] like Figure 1 As shown, the straight precast wall 1 includes a straight precast wall body in the shape of a straight plate. The straight precast wall 1 includes a first insulation board 11 embedded in the middle of the straight precast wall body. Multiple first connecting plates 12 are fixedly connected to the left and right sides of the first insulation board 11, which are arranged vertically and horizontally. The first connecting plates 12 extend in the front-back direction and have multiple first hook holes arranged vertically and horizontally.

[0048] First steel mesh 13 is provided on both the left and right sides of the first insulation board 11. The first steel mesh 13 is embedded in the precast wall body of the straight section. There is a gap between the first connecting plate 12 and the first steel mesh 13. The first insulation board 11, the first connecting plate 12, and the first steel mesh 13 form a whole load-bearing skeleton through the hooks 19. Figure 8 As shown, the hook and hanger 19 includes a main body rod 1901 extending in the left and right direction. One end of the main body rod 1901 is fixedly connected to a first hook rod 1902 extending downward, and the other end of the main body rod 1901 is fixedly connected to a second hook rod 1904 extending downward. A limiting rod 1903 extending downward is also fixedly connected to the bottom of the main body rod 1901.

[0049] like Figure 7 As shown, the second hook rod 1904 is movably inserted into the first hook hole, and the first hook rod 1902 and the limiting rod 1903 are respectively inserted on the left and right sides of the horizontal reinforcement of the second connecting plate 16 to improve the bending and displacement resistance of the first steel mesh 13 in the left and right directions, making its overall structure more stable.

[0050] Two first connecting steel sections 3 are fixedly embedded on the splicing surface of the straight precast wall body. The first connecting steel section 3 is an H-shaped steel structure extending in the vertical direction. One of the flanges of the first connecting steel section 3 is located inside the straight precast wall body, and the other flange is located outside the straight precast wall body. The other flange of the first connecting steel section 3 is provided with two rows of first through holes that are spaced apart on the left and right and open from front to back. At the connection between the other flange of the first connecting steel section 3 and the web of the first connecting steel section 3, multiple second through holes that are spaced apart vertically and open from left to right are opened. Both the first through holes and the second through holes are located outside the straight precast wall body.

[0051] The first connecting steel 3 is embedded in the straight section of the precast wall body. One end is fixedly connected to the first embedded rod 14, which is set at intervals between the upper and lower parts. The first embedded rod 14 is embedded in the straight section of the precast wall body. The first embedded rod 14 is an L-shaped rod structure. The first embedded rod 14 is hooked on the vertical bar of the first steel mesh 13.

[0052] The first embedded rod 14 can directly transmit the external tension on the first connecting steel 3 to the first steel mesh 13. Combined with the H-shaped steel structure used in the first connecting steel 3, the first connecting steel 3 is more stable during use and will not easily detach from the straight section of the precast wall body.

[0053] like Figure 3 As shown, the corner prefabricated wall 2 includes a right-angled corner prefabricated wall body. The corner prefabricated wall 2 includes a second insulation board 15 embedded in the middle of the corner prefabricated wall body. Multiple second connecting plates 16 are fixedly connected to the left and right sides of the second insulation board 15, which are arranged vertically and horizontally. The second connecting plate 16 is a right-angled plate structure. Multiple second hook holes are provided on the second connecting plate 16, which are arranged vertically and horizontally and are arranged vertically and horizontally along its extension direction.

[0054] The second insulation board 15 has a second steel mesh 17 on both the left and right sides, and there is a gap between the second connecting plate 16 and the second steel mesh 17. The second insulation board 15 and the second steel mesh 17 are both right-angled structures, and the second steel mesh 17 is embedded in the precast wall body of the corner section. The second insulation board 15, the second connecting plate 16 and the second steel mesh 17 also form a whole load-bearing skeleton through the hook 19. The second hook rod 1904 of the hook 19 is movably inserted into the second hook hole. The first hook rod 1902 and the limiting rod 1903 are respectively inserted on the left and right sides of the horizontal bar of the second steel mesh 17 to improve the bending and displacement resistance of the second steel mesh 17 in the left and right directions, making its overall structure more stable.

[0055] Two second connecting steel sections 4 are fixedly embedded on the splicing surface of the corner precast wall body. The second connecting steel sections 4 are fixedly connected to one end of the corner precast wall body and multiple second embedded rods 18 are fixedly connected to it. The second embedded rods 18 are embedded in the corner precast wall body. The second embedded rods 18 are all L-shaped rods and are hooked on the vertical bars of the second steel mesh 17.

[0056] The second connecting steel 4 is an H-shaped steel structure extending in the vertical direction. One of the flanges of the second connecting steel 4 is located inside the precast wall body of the corner section, and the other flange is located outside the precast wall body of the straight section. The other flange of the second connecting steel 4 is provided with two rows of third through holes that are spaced apart on the left and right and open from front to back. The third through holes correspond to the first through holes. At the connection between the other flange of the second connecting steel 4 and the web of the second connecting steel 4, there are multiple fourth through holes that are spaced apart vertically and open from left to right. Both the third and fourth through holes are located outside the precast wall body of the corner section.

[0057] The two corresponding first connecting steel sections 3, or the corresponding first connecting steel sections 3 and second connecting steel sections 4, within the installation area are all fixedly connected by high-strength flexible cables 5. To ensure a more balanced tensile and displacement strength in the front-to-back direction after the high-strength flexible cables 5 are connected to the first connecting steel sections 3 and second connecting steel sections 4, as follows... Figure 4 and Figure 5 As shown, one part of the high-strength soft cable 5 passes through the third through hole, the first through hole, the second through hole, the first through hole, and the third through hole in a U-shape in the horizontal direction, while the other part of the high-strength soft cable 5 passes through the first through hole, the third through hole, the fourth through hole, the third through hole, and the first through hole in a U-shape in the horizontal direction. The free end of the high-strength soft cable 5 is connected to its adjacent connecting rod 6, and the U-shaped opening direction of the high-strength soft cable 5 alternates between the vertical and horizontal directions to change direction in the front and back directions.

[0058] To facilitate the fixing of the high-strength flexible cable 5 and further improve the structural strength of the cantilever ends of the first connecting steel 3 and the second connecting steel 4, a fifth through hole is provided on both the web of the first connecting steel 3 and the web of the second connecting steel 4. Multiple connecting rods 6 are connected between the webs of the two corresponding first connecting steel 3 and the webs of the two corresponding second connecting steel 4, and the connecting rods 6 extend in the left-right direction.

[0059] Specifically, threaded rod segments 601 extending in the left and right directions are fixedly provided at both ends of the connecting rod 6, and the threaded rod segments 601 pass through the fifth through hole. Figure 6 As shown, the high-strength soft cable 5 includes a soft cable body 501, with cable rings 502 integrally connected to both ends of the soft cable body 501. The cable rings 502 are made of the same material as the soft cable body 501. Both cable rings 502 of the high-strength soft cable 5 are movably sleeved on the same threaded rod segment 601. A baffle 8 is provided on the outer side of the two cable rings 502 and sleeved on the threaded rod segment 601. The baffle 8 is an annular plate structure, and the outer diameter of the baffle 8 is larger than the outer diameter of the cable ring 502. A limiting nut 9 is provided on the outer side of the two baffles 8 and sleeved on the threaded rod segment 601. The limiting nut 9 is threadedly connected to the threaded rod segment 601.

[0060] There are gaps between the two corresponding first connecting steel sections 3, or between the corresponding first connecting steel sections 3 and second connecting steel sections 4, and the high-strength soft cable 5 between the two first connecting steel sections 3, or between the first connecting steel sections 3 and second connecting steel sections 4, is in a taut state.

[0061] Multiple reinforcing ribs 9, spaced apart on the left and right sides, are fixedly connected to one side of the connecting rod 6. The reinforcing ribs 9 extend in the vertical direction, and the reinforcing ribs 9 and the connecting rod 6 interweave to form a reinforcing steel mesh structure. The reinforcing ribs 9 and the connecting rod 6 can be connected by welding or by wire binding.

[0062] The connection installation area is filled with post-poured concrete 10. The first connecting steel 3, the second connecting steel 4, the high-strength soft cable 5, the connecting rod 6, and the reinforcing bar 9 are all located within the post-poured concrete 10.

[0063] In this embodiment, the high-strength soft cable 5 can be made of steel strand.

[0064] Working principle: (1) In the connection installation area of ​​the wall-to-wall connection node, the connection steel-high-strength soft cable-connecting steel is used instead of the traditional sleeve grouting connection method. During the pouring, the problems of grout leakage and steel bar eccentricity caused by the sleeve grouting connection are effectively avoided, which result in the grouting quality not meeting the requirements. At the same time, the connection steel-high-strength soft cable-connecting steel node connection method provides higher tensile strength at the wall-to-wall connection node compared with the steel bar sleeve connection method, and the connection quality is easier to guarantee.

[0065] Meanwhile, the connecting rods connect the two first connecting steel sections on the left and right, and the two second connecting steel sections on the left and right. Together with the first and second embedded rods, the force is further transmitted to the first and second steel mesh, so that the connecting steel section and the steel mesh form a whole under stress when resisting shear, thus strengthening the shear resistance of the connection node.

[0066] The reinforcing ribs 9 and connecting rods 6 are interwoven to form a reinforced steel mesh structure, which further improves the tensile and deformation resistance at the wall-to-wall connection nodes.

[0067] Example 2: A lightweight prefabricated wall structure system. This example differs from Example 1 in that the U-shaped openings formed by the high-strength flexible cables 5 in the same column have the same direction, while the U-shaped openings formed by the high-strength flexible cables 5 in the left and right columns have opposite directions. Other structural features are the same as in Example 1.

[0068] Example 3: A lightweight prefabricated wall structure system. This example differs from Example 1 in that the U-shaped openings formed by the high-strength flexible cables 5 within the connection installation area of ​​the same wall-to-wall connection node are oriented in the same direction, while the U-shaped openings formed by the high-strength flexible cables 5 within the connection installation area of ​​two adjacent wall-to-wall connection nodes are oriented in opposite directions. Other structural features are the same as in Example 1.

[0069] 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.
