Description

Technical Field

[0001] The present invention relates to the technical field of building structures, in particular to a prefabricated insulation board and a prefabricated wall combined casting connection structure. Background Art

[0002] The prefabricated insulation board and prefabricated wall combined cast connection structure is a structural form in which the insulation board and the prefabricated wall are connected in a specific way and cast into one piece.

[0003] The cast-in-place connection structure of prefabricated insulation panels and prefabricated walls mainly consists of five parts: prefabricated wall part, prefabricated insulation panel part, connection system, cast-in-place nodes and auxiliary structure. The synergistic effect of each part ensures the overall performance.

[0004] The construction of the existing prefabricated insulation board and prefabricated wall combined cast connection structure needs to follow the process of factory prefabrication, on-site hoisting, node connection, cast-in-place pouring and post-processing. However, in the existing node connection construction process, the steel truss is usually connected to the metal anchor bolts embedded in the insulation board by binding to realize the function of connecting the steel truss and the insulation board. This connection method requires the operator to repeat a large number of binding operation steps, which reduces the efficiency of the connection between the steel truss and the insulation board. Moreover, after the steel truss is fixedly connected to the insulation board, the support plate needs to be locked and connected. The two connection operations also increase the labor input. At the same time, the metal anchor bolts embedded on both sides of the insulation board are relatively independent. The connected steel truss continues to pull the connection between the insulation board and the metal anchor bolts. After long-term use, if the anchoring depth is insufficient or the bearing capacity does not meet the standard, there is a phenomenon that the connection between the metal anchor bolt and the insulation board becomes loose, which leads to separation of the insulation board and the prefabricated wall, thereby reducing the strength and stability of the combined cast connection of the prefabricated insulation board and the prefabricated wall.

[0005] Therefore, there is an urgent need to provide a combined cast-in-place connection structure that can improve the connection efficiency and connection stability of the steel truss and the insulation board. Summary of the Invention

[0006] Based on this, it is necessary to provide a prefabricated insulation board and prefabricated wall combined casting connection structure, which aims to solve the problems caused by the connection between the existing prefabricated insulation board and prefabricated wall before casting.

The steel bar frames are in a mesh structure and are hung on multiple snap hooks on the same side.

[0013] The prefabricated insulation board and prefabricated wall combined cast connection structure also includes an external support mechanism, which is symmetrically arranged in two and is respectively located on the outside of the two steel frames. The external support mechanism is connected to the locking part and is used to adjust the position of the locking part, driving the steel frame and the buckle part to be quickly fixed and limited.

[0014] Preferably, the external support mechanism includes a support plate arranged on the outside of the corresponding steel frame, and a plurality of distance portions are provided at one end of the support plate close to the steel frame.

[0015] Preferably, the locking portion further includes through holes respectively opened on a plurality of corresponding traction plates and threaded sleeves installed on the plurality of corresponding traction plates, the through holes slidingly penetrate and cooperate with the corresponding distance portions, and the threaded sleeves are threadedly connected to the locking screw.

[0016] Preferably, the distance portion includes a positioning sleeve that is slidably inserted into the corresponding penetration hole, the outer ring surface of the positioning sleeve is installed with a baffle ring, the interior of the positioning sleeve is provided with threaded teeth, and the positioning sleeve is threadedly connected to a distance-adjusting threaded tube at one end close to the insulation board.

[0017] Preferably, the limiting plate is symmetrically provided with two connection holes, one of which is slidably sleeved and connected to the straight section of the snap hook.

[0018] Preferably, the curved section of the snap hook is in a U-shaped structure, and the upper end of the curved section of the snap hook is plugged into and fitted with another connecting hole on the limiting plate.

[0037] Referring to Figure 1 , Figure 3 and Figure 5 The prefabricated insulation board and prefabricated wall combined pouring connection structure further includes an insulation board 2, which is vertically arranged in the middle of the mold frame 1.

[0038] In specific work, the mold frame 1 is installed and positioned at the pouring position.

[0039] Referring to Figure 1 , Figure 3 、 Figure 4 and Figure 7 The prefabricated insulation board and prefabricated wall combined cast connection structure also includes a clamping mechanism 3 connected to the insulation board 2, the clamping mechanism 3 includes a plurality of clamping parts 30 connected to the insulation board 2 and linearly evenly distributed from top to bottom, the clamping part 30 includes a plurality of connecting pipes 300 that are evenly distributed horizontally and installed through the insulation board 2.

[0040] In specific operation, the plurality of connecting pipes 300 are passed through the insulation board 2 during the molding process of the insulation board 2 , that is, the plurality of connecting pipes 300 are pre-buried in the insulation board 2 .

[0041] See Figure 4 、 Figure 7 and Figure 8 The two ends of the connecting tube 300 are respectively slidably penetrated by a snap hook 301, the curved section of the snap hook 301 is a U-shaped structure, and a plurality of evenly distributed limiting holes 302 are opened on the straight section of the snap hook 301. The two ends of the multiple connecting tubes 300 are respectively slidably penetrated by a limiting rod 303, and the limiting rod 303 is simultaneously plugged into the corresponding plurality of limiting holes 302.

[0042] See Figure 4 、 Figure 7 , mention 8, Figure 9 and Figure 10 The two ends of the multiple snap parts 30 are respectively connected to a locking part 31, and the locking part 31 includes a limiting plate 310 that is slidably sleeved on the multiple snap hooks 301 on the same side, and a connecting rod 311 is installed between the two adjacent limiting plates 310, and a traction plate 312 is installed between the multiple groups of upper and lower adjacent connecting rods 311 located in the middle.

[0043] See Figure 4 、 Figure 8 and Figure 9 Two connecting holes 315 are symmetrically opened on the limiting plate 310, one of the connecting holes 315 is slidably connected to the straight section of the snap hook 301, and the upper end of the curved section of the snap hook 301 is plugged into the other connecting hole 315 on the limiting plate 310.

[0044] During the specific work, after the insulation board 2 is formed, the multiple snap hooks 301 are divided into two groups, each snap hook 301 passes through the connecting hole 315 on the lower side of the corresponding limiting plate 310 and is passed through the corresponding end of the connecting pipe 300, and then a plurality of limiting rods 303 are selected, each limiting rod 303 respectively passes through the multiple connecting pipes 300 of the same height horizontally and is plugged into the limiting hole 302 corresponding to the straight section of the snap hook 301 in the connecting pipe 300, thereby realizing the limiting of the multiple snap hooks 301. At this time, the multiple snap hooks 301 support and limit the multiple limiting plates 310, and at the same time, the multiple limiting plates 310 are slidably connected to the multiple snap hooks 301. The multiple limiting holes 302 on the straight section of the snap hook 301 can adjust the position of the curved section of the snap hook 301, thereby changing the thickness of the prefabricated wall cast later to meet the requirements.

[0045] After the multiple snap hooks 301 are installed, the insulation board 2 is hoisted to the middle of the mold frame 1 by a crane.

[0046] See Figure 1 、 Figure 4 and Figure 7 The prefabricated insulation board and prefabricated wall combined cast connection structure also includes a steel frame 4, two of which are respectively located on both sides of the insulation board 2. The steel frame 4 is a mesh structure and is hung on multiple snap hooks 301 on the same side.

[0047] During the specific work, the insulation board 2 is hoisted to the middle of the mold frame 1, and the two mesh-structured steel frames 4 are respectively hung on multiple snap hooks 301 on both sides. The horizontal steel bars in the steel frames 4 are moved to the corresponding upper ends of the snap hooks 301, and multiple snap hooks 301 support and limit the steel frames 4.

[0048] Straight line segment Figure 6 、 Figure 9 and Figure 10 The locking portion 31 further includes through holes 313 respectively opened on a plurality of corresponding traction plates 312 and threaded sleeves 314 installed on the plurality of corresponding traction plates 312 .

[0049] See Figure 1 、 Figure 5 、 Figure 6 and Figure 7 The prefabricated insulation board and prefabricated wall combined cast connection structure also includes an external support mechanism 5, two of which are symmetrically arranged and are respectively located on the outside of the two steel frames 4. The external support mechanism 5 is connected to the locking part 31. The external support mechanism 5 is used to adjust the position of the locking part 31 on the corresponding multiple snap hooks 301, driving the steel frame 4 and the snap part 30 to be quickly fixed and limited.

[0050] See Figure 1 and Figure 6The outer support mechanism 5 comprises support plates 50 arranged outside the corresponding reinforcing frame 4, and the support plates 50 are provided with a plurality of distance parts 51 at one end close to the reinforcing frame 4, the distance parts 51 penetrate the corresponding traction plates 312 and are attached to the insulation board 2, and the penetrating holes 313 slide and penetrate the corresponding distance parts 51.

[0051] Referring to Figure 6 , Figure 7 and Figure 10 , the distance part 51 comprises a positioning sleeve 510 slidingly penetrating the corresponding penetrating hole 313, the outer ring surface of the positioning sleeve 510 is provided with a blocking ring 512, the inside of the positioning sleeve 510 is provided with a threaded tooth, and a distance adjusting threaded pipe 511 is threadedly connected at one end of the positioning sleeve 510 close to the insulation board 2, a plurality of feeding openings 513 for the entry of concrete are formed on the distance adjusting threaded pipe 511, and a plurality of contact plates are uniformly distributed and arranged on the distance adjusting threaded pipe 511 close to the insulation board 2.

[0052] In specific work, according to the required thickness of the prefabricated wall, a plurality of distance adjusting threaded pipes 511 are sequentially rotated, the distance adjusting threaded pipe 511 moves in the positioning sleeve 510, so that the length between the positioning sleeve 510 and the distance adjusting threaded pipe 511 matches the thickness of the prefabricated wall, then a plurality of adjusted positioning sleeves 510 penetrate the corresponding penetrating holes 313, until the plurality of contact plates on the distance adjusting threaded pipe 511 are tightly attached to the insulation board 2, the feeding openings 513 are used for the entry of concrete, the phenomenon of hollowing after pouring of the prefabricated wall is avoided, and the quality of pouring of the prefabricated wall is ensured.

[0053] Referring to Figure 6 and Figure 10 , a plurality of locking screws 52 are penetratingly arranged on the support plate 50, and the threaded sleeve 314 is threadedly connected with the locking screw 52.

[0054] Referring to Figure 9 , the plurality of connecting rods 311 include horizontal and vertical states, and the plurality of connecting rods 311 form a rectangular grid structure.

[0055] When working, after the multiple distance parts 51 are inserted into the penetration holes 313, the two supporting plates 50 are respectively attached to the multiple distance parts 51 ends on both sides, and then multiple locking screws 52 are selected, and the multiple locking screws 52 are sequentially passed through the supporting plates 50 and threadedly connected with the threaded sleeves 314. After the locking screws 52 are threadedly connected with the threaded sleeves 314, the threaded sleeves 314 are driven to move toward the supporting plate 50 by the rotation of the locking screws 52. The threaded sleeves 314 drive the multiple limiting plates 310 to slide on the corresponding buckle hooks 301 through the traction plates 312 and the multiple connecting rods 311, and push the steel frames 4 on the multiple buckle hooks 301 toward the bent sections of the buckle hooks 301 until the transverse steel bars on the steel frame 4 are tightly attached to the bent sections of the buckle hooks 301. At this time, the limiting plates 3 The other connecting hole 315 on 10 is plugged into and matched with the curved section of the snap hook 301, and the cooperation between the limiting plate 310 and the curved section of the snap hook 301 realizes the function of limiting the steel frame 4. At the same time, the limiting plate 310 shapes and limits the curved section of the snap hook 301 to avoid the curved section of the snap hook 301 being deformed by the thrust of the steel frame 4, thereby ensuring the stability of the snap hook 301 in limiting the steel frame 4. When the steel frame 4 is tightly attached to the curved section of the snap hook 301, the baffle ring 512 on the positioning sleeve 510 is tightly attached to the traction plate 312, that is, the movement of the traction plate 312 is limited to avoid the steel frame 4 from overfeeding, and then the remaining locking screw 52 is connected to the corresponding threaded sleeve 314 to realize the function of installing the support plate 50.

[0056] When the support plate 50 is installed, the steel frame 4 can be tightened and limited. There is no need for the operator to connect the steel frame 4 to the insulation board 2 through multi-point binding, which reduces the operation steps of connecting the steel frame 4 and improves the efficiency of connecting the steel frame 4 and the insulation board 2. When the two steel frames 4 are pulled into the limit, they are pulled by the buckle part 30, which reduces the pulling of the steel frame 4 on the connection between the insulation board 2 and ensures the firmness of the connection between the steel frame 4 and the insulation board 2.

[0057] After the two support plates 50 are installed, concrete is poured into the space formed by the support plates 50, the insulation plates 2 and the mold frame 1, and vibrated. After the concrete solidifies and takes shape, the mold frame 1 and the support plates 50 are removed, and the prefabricated insulation plates and prefabricated walls are cast together.
