Description

Technical Field

[0001] This invention relates to the field of building structure technology, and in particular to a precast insulation board and precast wall combined casting connection structure. Background Technology

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

[0003] The precast insulation board and precast wall combined casting connection structure is mainly composed of five parts: precast wall part, precast insulation board part, connection system, cast-in-place node and auxiliary structure. The synergistic effect of each part ensures the overall performance.

[0004] The existing construction of precast insulation panels and precast walls combined with cast-in-place structures requires following a process of factory prefabrication, on-site hoisting, joint connection, cast-in-place pouring, and post-construction treatment. However, in the existing joint connection process, the steel truss is usually connected to the metal anchors embedded in the insulation panel by binding, which requires operators to repeat a large number of binding operations, reducing the efficiency of the connection between the steel truss and the insulation panel. Moreover, after the steel truss and the insulation panel are fixedly connected, the support plate also needs to be locked, which increases the labor input. At the same time, the metal anchors embedded on both sides of the insulation panel are relatively independent. After the connection, the steel truss continuously pulls on the connection between the insulation panel and the metal anchors. After long-term use, if the anchoring depth is insufficient or the bearing capacity is not up to standard, the connection between the metal anchors and the insulation panel may loosen, leading to the separation of the insulation panel and the precast wall, which reduces the strength and stability of the precast insulation panel and precast wall combined with cast-in-place structure.

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

[0006] Therefore, it is necessary to provide a casting connection structure that combines precast insulation panels and precast walls, in order to solve the problems that arise when connecting precast insulation panels and precast walls before casting.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a precast insulation board and precast wall combined casting connection structure, including a mold frame.

[0008] The precast insulation board and precast wall combined casting connection structure also includes an insulation board, which is vertically set in the middle of the mold frame.

[0009] The precast insulation board and precast wall combined casting connection structure also includes a snap-fit ​​mechanism connected to the insulation board. The snap-fit ​​mechanism includes multiple snap-fit ​​parts connected to the insulation board and linearly and evenly distributed from top to bottom. Both ends of the multiple snap-fit ​​parts are connected to a locking part.

[0010] The buckle part includes multiple horizontally evenly distributed connecting pipes that are installed through the insulation board. Each end of the connecting pipe is slidably provided with a buckle hook. Multiple evenly distributed limiting holes are opened on the straight section of the buckle hook. Both ends of the multiple connecting pipes are slidably provided with limiting rods, and the limiting rods are simultaneously inserted and engaged with the corresponding multiple limiting holes.

[0011] The locking part includes limiting plates that are slidably sleeved on multiple buckle hooks on the same side, and a connecting rod is installed between two adjacent limiting plates. A traction plate is installed between multiple sets of upper and lower adjacent connecting rods located in the middle.

[0012] The precast insulation board and precast wall combined casting connection structure also includes a steel reinforcement frame. There are two steel reinforcement frames, which are located on both sides of the insulation board. The steel reinforcement frames are in the form of a mesh structure and are hung on multiple clips on the same side.

[0013] The precast insulation board and precast wall combined casting connection structure also includes an external support mechanism. Two external support mechanisms are symmetrically arranged and located on the outside of two steel reinforcement frames respectively. The external support mechanism is connected to the locking part and is used to adjust the position of the locking part, so as to drive the steel reinforcement frame and the buckle part to be quickly fixed and limited.

[0014] Preferably, the external support mechanism includes a support plate disposed on the outside of the corresponding steel reinforcement frame. The end of the support plate near the steel reinforcement frame is provided with multiple spacers. The spacers pass through the corresponding traction plate and are attached to the insulation plate. Multiple locking screws are passed through the support plate.

[0015] Preferably, the locking part further includes through holes respectively opened on multiple corresponding traction plates and threaded sleeves installed on multiple corresponding traction plates. The through holes are slidably connected to the corresponding fixed distance parts, and the threaded sleeves are threadedly connected to the locking screw.

[0016] Preferably, the positioning part includes a positioning sleeve that slides through the corresponding through hole, a spacer ring is installed on the outer ring surface of the positioning sleeve, the positioning sleeve is provided with threaded teeth, and an adjusting threaded tube is threadedly connected to the end of the positioning sleeve closest to the insulation board.

[0017] Preferably, the limiting plate has two symmetrical connecting holes, one of which is slidably connected to the straight segment of the buckle hook.

[0018] Preferably, the bent section of the buckle hook has a U-shaped structure, and the upper end of the bent section of the buckle hook is inserted into another connecting hole on the limiting plate.

[0019] Preferably, the adjustable threaded pipe has multiple feed openings for concrete entry, and multiple circumferentially evenly distributed contact plates are installed at one end of the adjustable threaded pipe near the insulation board.

[0020] Preferably, the multiple links include both horizontal and vertical states, and the multiple links form a rectangular grid structure.

[0021] In summary, the present invention has the following beneficial technical effects: 1. The snap-fit ​​part used in the present invention can provide multi-point support for the steel reinforcement frame, and in conjunction with the locking part, it can realize the quick connection and positioning of the steel reinforcement frame and the insulation board. It eliminates the need for operators to connect the steel reinforcement frame and the insulation board through multi-point binding, reducing the steps of repeated binding. Moreover, only one locking step is needed to achieve the overall connection of the insulation board, steel reinforcement frame and support plate, effectively improving the connection efficiency of the insulation board, steel reinforcement frame and support plate and reducing the input of manpower.

[0022] 2. The multiple snap-fit ​​parts used in this invention can connect two steel reinforcement frames simultaneously, and the two steel reinforcement frames pull each other, so that the insulation board is in a stress-free state. This avoids the phenomenon of continuous pulling of the steel reinforcement frame at the connection with the insulation board, and avoids the phenomenon of separation between the steel reinforcement frame and the insulation board. This ensures the stability of the connection between the steel reinforcement frame and the insulation board, and thus ensures the stability of the precast insulation board and the precast wall after casting.

[0035] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] See Figure 1 and Figure 2 A precast insulation board and precast wall combined casting connection structure, including mold frame 1.

[0037] See Figure 1 , Figure 3 and Figure 5 The precast insulation board and precast wall combined casting connection structure also includes insulation board 2, which is vertically set in the middle of mold frame 1.

[0038] In practice, the mold frame 1 is installed and positioned at the pouring location.

[0039] See Figure 1 , Figure 3 , Figure 4 and Figure 7 The precast insulation board and precast wall combined casting connection structure also includes a snap-fit ​​mechanism 3 connected to the insulation board 2. The snap-fit ​​mechanism 3 includes multiple snap-fit ​​parts 30 connected to the insulation board 2 and linearly and evenly distributed from top to bottom. The snap-fit ​​parts 30 include multiple horizontally evenly distributed connecting pipes 300 that are installed through the insulation board 2.

[0040] In practice, multiple connecting pipes 300 are inserted into the insulation board 2 during the forming process of the insulation board 2, that is, multiple connecting pipes 300 are pre-embedded in the insulation board 2.

[0041] See Figure 4 , Figure 7 and Figure 8 Both ends of the connecting pipe 300 are respectively provided with a buckle hook 301. The curved section of the buckle hook 301 is U-shaped. Multiple evenly distributed limiting holes 302 are opened on the straight section of the buckle hook 301. Both ends of the multiple connecting pipes 300 are respectively provided with a limiting rod 303. The limiting rod 303 is simultaneously inserted and engaged with the corresponding multiple limiting holes 302.

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

[0043] See Figure 4 , Figure 8 and Figure 9 The limiting plate 310 has two symmetrical connecting holes 315. One of the connecting holes 315 is slidably connected to the straight section of the buckle hook 301, and the upper end of the curved section of the buckle hook 301 is inserted into the other connecting hole 315 on the limiting plate 310.

[0044] In practice, after the insulation board 2 is formed, 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 inserted into the end of the corresponding connecting pipe 300. Then, multiple limiting rods 303 are selected. Each limiting rod 303 passes horizontally through multiple connecting pipes 300 at the same height and is inserted into the limiting hole 302 corresponding to the straight section of the snap hook 301 in the connecting pipe 300, thereby limiting the multiple snap hooks 301. At this time, the multiple snap hooks 301 support and limit the multiple limiting plates 310. At the same time, the multiple limiting plates 310 and the multiple snap hooks 301 are slidably connected. The multiple limiting holes 302 on the straight section of the snap hook 301 can adjust the position of the bent section of the snap hook 301, thereby changing the thickness of the precast wall poured later to meet the requirements.

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

[0046] See Figure 1 , Figure 4 and Figure 7 The precast insulation board and precast wall combined casting connection structure also includes a steel bar frame 4. There are two steel bar frames 4, which are located on both sides of the insulation board 2. The steel bar frames 4 have a mesh structure and are hung on multiple buckle hooks 301 on the same side.

[0047] In the actual operation, the insulation board 2 is hoisted to the middle of the mold frame 1, and the two mesh-structured steel bar frames 4 are hung on multiple buckle hooks 301 on both sides respectively. The horizontal steel bars in the steel bar frame 4 are moved to the upper end of the corresponding buckle hook 301, and the multiple buckle hooks 301 support and limit the steel bar frame 4.

[0048] See straight segment Figure 6 , Figure 9 and Figure 10 The locking part 31 also includes through holes 313 respectively opened on a plurality of corresponding traction plates 312 and threaded sleeves 314 installed on a plurality of corresponding traction plates 312.

[0049] See Figure 1 , Figure 5 , Figure 6 and Figure 7 The precast insulation board and precast wall combined casting connection structure also includes an external support mechanism 5. Two external support mechanisms 5 are symmetrically arranged and located on the outside of the two steel reinforcement frames 4 respectively. 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 buckle hooks 301, so as to drive the steel reinforcement frame 4 and the buckle part 30 to be quickly fixed and limited.

[0050] See Figure 1 and Figure 6The external support mechanism 5 includes a support plate 50 set on the outside of the corresponding steel bar frame 4. The support plate 50 is provided with a plurality of spacers 51 at one end near the steel bar frame 4. The spacers 51 pass through the corresponding traction plate 312 and are attached to the insulation plate 2. The through hole 313 slides through and engages with the corresponding spacer 51.

[0051] See Figure 6 , Figure 7 and Figure 10 The positioning part 51 includes a positioning sleeve 510 that slides through the corresponding through hole 313. A baffle ring 512 is installed on the outer ring surface of the positioning sleeve 510. The positioning sleeve 510 has threaded teeth inside. An adjustable threaded tube 511 is threadedly connected to one end of the positioning sleeve 510 closest to the insulation board 2. The adjustable threaded tube 511 has multiple feed openings 513 for concrete to enter. Multiple circumferentially evenly distributed contact plates are installed on one end of the adjustable threaded tube 511 closest to the insulation board 2.

[0052] In practice, according to the required thickness of the precast wall, multiple adjustable threaded tubes 511 are rotated in sequence. The adjustable threaded tubes 511 move within the positioning sleeves 510 so that the length between the positioning sleeves 510 and the adjustable threaded tubes 511 matches the thickness of the precast wall. Then, multiple adjusted positioning sleeves 510 are passed through the corresponding through holes 313 until multiple contact plates on the adjustable threaded tubes 511 are in close contact with the insulation board 2. The feed opening 513 is used for the entry of concrete to ensure that the precast wall does not have a hollow phenomenon after pouring and to ensure the quality of the precast wall pouring.

[0053] See Figure 6 and Figure 10 Multiple locking screws 52 are installed on the support plate 50, and the threaded sleeve 314 is threadedly connected to the locking screws 52.

[0054] See Figure 9 The multiple links 311 include both horizontal and vertical states, and the multiple links 311 form a rectangular grid structure.

[0055] In practice, after multiple spacers 51 are inserted into the through holes 313, two support plates 50 are attached to the ends of the multiple spacers 51 on both sides. Then, multiple locking screws 52 are selected and sequentially inserted through the support plates 50 and threadedly connected to the threaded sleeves 314. After the locking screws 52 are threadedly connected to the threaded sleeves 314, the rotation of the locking screws 52 drives the threaded sleeves 314 to move towards the support plates 50. The threaded sleeves 314, through the traction plate 312 and multiple connecting rods 311, drive multiple limiting plates 310 to slide on the corresponding snap hooks 301, and push the steel reinforcement frames 4 on the snap hooks 301 towards the bent section of the snap hooks 301 until the horizontal steel reinforcement on the steel reinforcement frames 4 is tightly attached to the bent section of the snap hooks 301. At this time, the limiting plates 310 are closed. Another connecting hole 315 on the 10 is inserted into the bent section of the snap hook 301. The engagement of the limiting plate 310 with the bent section of the snap hook 301 enables the limiting of the rebar frame 4. At the same time, the limiting plate 310 shapes and limits the bent section of the snap hook 301, preventing the bent section of the snap hook 301 from deforming due to the thrust of the rebar frame 4, thus ensuring the stability of the snap hook 301 in limiting the rebar frame 4. When the rebar frame 4 is in close contact with the bent section of the snap hook 301, the partition ring 512 on the positioning sleeve 510 is in close contact with the traction plate 312, that is, limiting the movement of the traction plate 312, preventing the rebar frame 4 from overfeeding. 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] While the support plate 50 is being installed, it can also tighten and limit the rebar frame 4, eliminating the need for operators to connect the rebar frame 4 to the insulation board 2 through multi-point binding. This reduces the number of steps required to connect the rebar frame 4 and improves the efficiency of the connection between the rebar frame 4 and the insulation board 2. Furthermore, when the two rebar frames 4 are pulled into the limit position, they are pulled together by the buckle part 30, which reduces the pulling of the rebar frame 4 on the connection point of the insulation board 2 and ensures the firmness of the connection between the rebar 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 plate 50, the insulation board 2 and the mold frame 1, and vibrated. After the concrete has solidified, the mold frame 1 and the support plate 50 are removed, and the precast insulation board and the precast wall are poured together.
