Description

Technical Field

[0001] This invention relates to the field of precast wall connection technology, and in particular to a connection structure between a precast solid wall and a precast double-sided composite wall. Background Technology

[0002] Precast walls are a type of wall system in modern industrialized construction. Their components are prefabricated in specialized factories or on-site, then transported to the construction site for rapid assembly to form exterior walls, interior partitions, or load-bearing walls. Compared to traditional on-site masonry walls, the core advantages of precast walls lie in the quality control afforded by industrialized production, the significantly shortened construction cycle, and the environmental benefits of reducing on-site wet work.

[0003] Precast walls can be classified by function and location into interior wall panels and exterior wall panels; and by structural materials and systems into precast concrete wall panels, precast shear walls, lightweight precast wall panels, and other types. When constructing buildings using precast walls, solid walls are used as the main load-bearing structure, while double-sided composite walls are often used as the main frame structure for insulation and soundproofing walls. During the construction process, insulation and soundproofing materials are injected into the composite wall. In actual construction, the steel bars on the precast wall are connected to the tied steel cage, and concrete is poured outside the steel cage. This method can ensure the connection effect between the multiple precast walls. However, because the precast double-sided composite wall itself is hollow, it is easy for concrete to be poured first, and the concrete will enter the interior of the composite wall. This will ultimately affect the effect of the insulation and soundproofing materials after they are filled into the interior of the composite wall (if the insulation and soundproofing materials are filled into the interior of the composite wall first, they will easily spread to the concrete filling area, ultimately affecting the strength of the concrete after pouring). Furthermore, a precast concrete wall panel, its system, and manufacturing method (publication number CN113718982A) involves pre-reserving cavities in the precast concrete wall panel. After positioning and installation, the pre-reserved reinforcing bars of the lower precast concrete wall panel are inserted into the hollow wall body of the upper precast concrete wall panel, and the two precast concrete wall panels are vertically connected by post-cast concrete. This method requires less post-cast concrete, is simple to operate, and has higher construction efficiency than the connection method using grouting sleeves. Compared with the double-sided composite shear wall system, it reduces the amount of post-cast concrete work, which to some extent reflects the aforementioned problems. Therefore, how to provide a connection structure between a precast solid wall and a precast double-sided composite wall is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] One objective of this invention is to propose a connection structure between a precast solid wall and a precast double-sided composite wall, in order to solve the problem that when the steel bars on the precast wall are connected to the bundled steel cage and concrete is poured outside the steel cage, the precast double-sided composite wall itself is in a hollow state, which easily leads to the concrete being poured first and then entering the interior of the composite wall, ultimately affecting the effect of the insulation, sound insulation and other materials filling the interior of the composite wall.

[0005] According to an embodiment of the present invention, a connection structure between a precast solid wall and a precast double-sided composite wall is applied between a solid wall structure and a composite wall structure, including a casting template and a partition plate. Two casting templates are provided and are arranged opposite each other. The isolation plate is placed between the two casting templates; The composite wall structure includes a composite wall back panel and a composite wall front panel. Multiple longitudinal and transverse steel bars are embedded inside the composite wall front panel and the composite wall back panel to form a mesh structure. The composite wall front panel and the composite wall back panel are connected by embedded tie bars. Multiple first movable slots are opened inside the partition plate. Multiple locking components are provided between the two casting templates. Each locking component includes a tension bar. Limiting slots are opened inside both ends of the tension bar. Pins are inserted into the interior of each of the two limiting slots. One end of each of the transverse reinforcing bars passes through the interior of the first movable slots and is fixed to the reinforcing cage tied between the two casting templates.

[0006] Preferably, the surface of the isolation plate away from the composite wall structure is welded with multiple positioning seats, the multiple positioning seats respectively cover the outside of multiple first movable slots, the internal of the positioning seats is pin-connected with a pin plate, and the surface of the pin plate away from the isolation plate is integrally formed with a plug.

[0007] Preferably, the plug is fastened to the outside of one end of two transverse reinforcing bars on the same horizontal plane, and one end of the plug is in contact with one side of the isolation plate and the surface of the composite wall back plate, while the other side of the isolation plate is flush with the surface of the composite wall panel and in contact with the surface of a casting template.

[0008] Preferably, the tops of multiple pins on one of the locking components are connected to a vertical plate, and a figure-eight plate is provided on the side of the vertical plate away from the pins; the bottom of the figure-eight plate is hooked to the bottom of the vertical plate and is located directly above the vertical plate on the bottom locking component.

[0009] Preferably, the upright plate has a movable groove inside, and a locking block is slidably connected inside the movable groove. A connecting slot is formed inside both sides of the locking block, and a trapezoidal locking strip is slidably connected inside the connecting slot. A first storage column groove is formed on the top of the trapezoidal locking strip near the center of the locking block, and a first spring is installed inside the first storage column groove. Multiple positioning slots are formed on both sides of the upright plate. The locking block is assembled and fixed to one side of the top of the seven-shaped plate. The first spring is supported between the side wall of the connecting slot and the side wall of the first storage column groove. The trapezoidal locking strip is engaged inside the positioning slot, with its inclined surface facing downwards and adapted to the inner wall of the positioning slot.

[0010] Preferably, the trapezoidal clip has a positioning rod inside, one end of which passes through the inside of the first spring and is connected and fixed to the side wall of the connecting slot.

[0011] Preferably, the trapezoidal locking strip has a second movable slot at its bottom near the center of the locking block, and trapezoidal pressure strips are slidably connected inside both second movable slots. The inclined surfaces of the two trapezoidal pressure strips face each other, and a base plate is integrally formed at one end of each trapezoidal pressure strip. The seven-shaped plate has a storage slot inside its interior facing the upright plate, and an adjusting screw is threaded inside the seven-shaped plate. The base plate is movably connected inside the storage slot, and the cross-section of the connecting slot is L-shaped. The trapezoidal pressure strip extends into the interior of the second movable slot through the connecting slot.

[0012] Preferably, a filling component is provided between the multiple tie bars and isolation plates in the longitudinal row, the solid wall structure includes a solid wall body, and multiple steel rings embedded in the four sides of the solid wall body are provided therein. The multiple steel rings located between the two casting templates are fixed to the steel cage tied between the two casting templates.

[0013] Preferably, the filling component includes two facing strips, with guide slopes machined on the top and bottom of the two strips facing away from each other, and multiple guide slopes opened inside the two strips. The multiple guide slopes inside the two strips are coaxially arranged, and a second spring is provided inside the two guide slopes in the coaxial state. The two strips are symmetrical about the origin.

[0014] Preferably, both of the strips have multiple second storage slots inside, and the multiple second storage slots inside the two strips are coaxially arranged. The two second storage slots in the coaxial state are provided with the same long bolt, and one end of the long bolt is threaded with a nut.

[0015] The beneficial effects of this invention are: This invention separates the composite wall structure from the two casting templates by having the side of the isolation plate abut against the surface of the composite wall back panel. When the side of the isolation plate abuts against the side of the composite wall panel, the concrete enters between the composite wall panel and the composite wall back panel when the concrete wall is poured in the two casting templates. This reduces the amount of concrete entering between the composite wall panel and the composite wall back panel, and avoids affecting the effect of filling the space between the composite wall panel and the composite wall back panel with sound insulation, heat insulation and other materials. This invention utilizes a first spring supported between the side wall of the connecting slot and the side wall of the first receiving column slot. When the locking block slides down to the positioning slot inside the movable slot, the trapezoidal locking strip extends out from inside the connecting slot and engages with the inside of the positioning slot. This restricts the locking block from moving upward inside the movable slot, facilitating the adjustment of the bottom of the seven-shaped plate connected to the locking block to contact the top of the vertical plate directly below. This also helps to achieve the effect of simultaneously striking multiple pins when striking the top vertical plate. This invention controls the seat plate to push two trapezoidal pressure strips into the interior of the second movable slot by adjusting the threaded connection of the adjusting screw and the seven-shaped plate. With the cooperation of the inclined inner wall of the trapezoidal pressure strip and the inclined side wall of the second movable slot, the trapezoidal locking strip is retracted into the serial slot and the first spring is compressed. This can control the locking block to move smoothly inside the movable slot, which facilitates the subsequent removal of multiple pins from the corresponding limiting slots. This invention installs the filling component entirely between two casting templates, with one strip abutting against multiple end caps and another strip abutting against one side of multiple vertical tie bars. This facilitates a tight fit between the isolation plate carrying multiple end caps and the composite wall panel and back panel, preventing the isolation plate from moving between the composite wall panel and back panel when pouring concrete between the two casting templates.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0019] Example 1: The technical solution in this application is to solve the problem that the above-mentioned method of connecting the steel bars on the precast wall to the bundled steel cage and pouring concrete outside the steel cage is prone to problems because the precast double-sided composite wall itself is in a hollow state. This can easily lead to concrete being poured first, and then entering the interior of the composite wall, ultimately affecting the effectiveness of the insulation and soundproofing materials after filling. The overall approach is as follows: To address the problems existing in the prior art, the present invention provides a schematic diagram of a connection structure between a precast solid wall and a precast double-sided composite wall, as shown in the reference diagram. Figures 1 to 4 , Figures 8 to 13 As shown, the connection structure is applied between the solid wall structure 2 and the composite wall structure 3, including two casting templates 4 facing each other and an isolation plate 7 set between the two casting templates 4. The composite wall structure 3 includes a composite wall back plate 302 and a composite wall panel 301. Multiple longitudinal steel bars 303 and transverse steel bars 304 are embedded inside the composite wall panel 301 and the composite wall back plate 302, forming a mesh structure. The composite wall panel 301 and the composite wall back plate 302 are connected by embedded tie bars. The solid wall structure 2 includes a solid wall 201. Multiple steel bar rings 202 are set at each of the four sides of the solid wall 201. The multiple steel bar rings 202 located between the two casting templates 4 are fixed to the steel cage tied between the two casting templates 4. The partition plate 7 has multiple first movable slots 11 inside. Multiple positioning seats 10 are welded to the surface of the partition plate 7 away from the composite wall structure 3. The multiple positioning seats 10 cover the outside of the multiple first movable slots 11 respectively. The positioning seats 10 are pin-connected to the inside of the positioning seats 10. A plug 8 is integrally formed on the surface of the pin plate 9 away from the partition plate 7. The tie bars between the composite wall panel 301 and the composite wall back plate 302 are connected at both ends to a mesh structure formed by the longitudinal reinforcement 303 and the transverse reinforcement 304, respectively. This mesh structure is connected to the reinforcement structure inside the composite wall panel 301 or the composite wall back plate 302, which can ensure the structural strength of the entire composite wall structure 3 and make the space between the composite wall panel 301 and the composite wall back plate 302 hollow, which is conducive to filling the space between the composite wall panel 301 and the longitudinal reinforcement 303 with thermal insulation adhesive, sound insulation and other materials. Multiple locking components 5 are provided between the two casting templates 4. Each locking component 5 includes a tension strip 504. Limiting slots 15 are opened inside both ends of the tension strip 504. Pins 502 are plugged into the interior of each of the two limiting slots 15. Among them, a steel cage is tied between the two casting formwork 4 to form a stable support inside the wall when the concrete wall is poured later. One end of multiple horizontal steel bars 304 extends from between the composite wall panel 301 and the composite wall back plate 302 and is processed into a hook shape. When the steel cage is tied between the two casting formwork 4, one end of the horizontal steel bar 304 can be hooked on the steel cage. After the concrete wall pouring is completed, the connection between the solid wall structure 2 and the composite wall structure 3 can be made reliable. Secondly, one end of each of the multiple transverse steel bars 304 passes through the interior of the multiple first movable slots 11 and is fixed to the steel cage tied between the two casting templates 4. Since the plug 8 is fastened to the outside of one end of the two transverse steel bars 304 on the same horizontal plane, the plug 8 can be made to fit one side of the partition plate 7 with the surface of the composite wall back plate 302, ensuring that the partition plate 7 is perpendicular to the composite wall panel 301 and the composite wall back plate 302. The other side of the partition plate 7 is flush with the surface of the composite wall panel 301 and fits with the surface of one casting template 4. This can prevent gaps from appearing between the surface of the composite wall panel 301 and the surface of the casting template 4 when the two casting templates 4 clamp the composite wall structure 3. Meanwhile, in order to make it easy to fix the plug 8 to the surface of the isolation plate 7, simply pin the pin plate 9 to the inside of the positioning seat 10 to ensure that the plug 8 and the first movable slot 11 are aligned. Furthermore, by passing a tension bar 504 through the interior of two casting templates 4 and inserting a pin 502 into the limiting slot 15 at one end of the tension bar 504, the two pins 502 can be pressed towards the center at both ends of the tension bar 504 by striking the trapezoidal pin 502 towards the bottom, thereby achieving the effect of fixing the casting template 4. In some examples, multiple pins 502 on a locking assembly 5 are connected to a vertical plate 501 at their top. A seven-shaped plate 503 is provided on the side of the vertical plate 501 away from the pins 502. A movable slot 16 is provided inside the vertical plate 501. A locking block 505 is slidably connected inside the movable slot 16. A series groove 19 is provided on both sides of the locking block 505. The cross-section of the series groove 19 is L-shaped. A trapezoidal locking strip 509 is slidably connected inside the series groove 19. A first storage column groove 1 is provided on the top of the side of the trapezoidal locking strip 509 near the center of the locking block 505. A first spring 510 is provided inside the first storage column groove 1. Multiple positioning slots 14 are provided on both sides of the vertical plate 501. In this way, by hooking the bottom of the seven-shaped plate 503 to the bottom of the upright plate 501 and placing it directly above the upright plate 501 on the bottom locking assembly 5, the seven-shaped plate 503 and the upright plate 501 can be used as a whole. When the top of the upright plate 501 is struck to the bottom, the seven-shaped plate 503 can form a support between the two upright plates 501 in the vertical direction to ensure that multiple pins 502 in the longitudinal direction can be controlled to move to the bottom inside the limiting slots 15 at the corresponding positions. Secondly, in order for the seven-character board 503 to adapt to the distance between the upper and lower upright boards 501, such as Figures 9 to 13 As shown, the locking block 505 is assembled and fixed to one side of the top of the seven-shaped plate 503. The inclined surface of the trapezoidal clip 509 faces downward and is adapted to the inner wall of the positioning slot 14. It is supported by the first spring 510 between the side wall of the connecting slot 19 and the side wall of the first storage column slot 1. When the locking block 505 slides down to the bottom of the movable slot 16 to the positioning slot 14, the trapezoidal clip 509 extends out from the inside of the connecting slot 19 and engages with the inside of the positioning slot 14. This can restrict the locking block 505 from moving up inside the movable slot 16, making it easier to adjust the bottom of the seven-shaped plate 503 connected to the locking block 505 to contact the top of the vertical plate 501 directly below. Furthermore, to improve the stability of the trapezoidal strip 509 sliding within the connecting slot 19, such as... Figure 11 As shown, the trapezoidal clip 509 is provided with a positioning rod 511 inside. By passing one end of the positioning rod 511 through the inside of the first spring 510 and connecting and fixing it to the side wall of the connecting slot 19, the trapezoidal clip 509 is supported to slide outside the positioning rod 511, which can assist the trapezoidal clip 509 to slide smoothly inside the connecting slot 19. Furthermore, to facilitate control of the locking block 505 moving upwards within the movable slot 16, such as... Figures 10 to 13As shown, the trapezoidal retaining strip 509 has a second movable slot 17 at its bottom near the center of the locking block 505. Trapezoidal pressure strips 508 are slidably connected inside both second movable slots 17. The inclined surfaces of the two trapezoidal pressure strips 508 face each other. A base plate 506 is integrally formed at one end of each trapezoidal pressure strip 508. A storage slot 18 is opened inside the side of the swivel plate 503 facing the upright plate 501. An adjusting screw 507 is threaded inside the swivel plate 503, allowing the base plate 506 to be movably connected to the storage slot 18. Inside, the trapezoidal pressure strip 508 extends into the interior of the second movable slot 17 via the connecting slot 19. By adjusting the threaded connection between the adjusting screw 507 and the seven-shaped plate 503, the seat plate 506 can be controlled to push the two trapezoidal pressure strips 508 into the interior of the second movable slot 17. With the cooperation of the inclined inner wall of the trapezoidal pressure strip 508 and the inclined side wall of the second movable slot 17, the trapezoidal locking strip 509 is retracted into the interior of the connecting slot 19, and the first spring 510 is compressed, which can control the locking block 505 to move smoothly inside the movable slot 16.

[0020] In this embodiment, by opening multiple first movable slots 11 inside the isolation plate 7 and setting multiple plugs 8 covering the first movable slots 11 on one side of the isolation plate 7, and fixing the plugs 8 and the isolation plate 7 with pins 9 and positioning seats 10, the isolation plate 7 can abut against the surface of the composite wall back plate 302 on the side and the isolation plate 7 abut against the side of the composite wall panel 301, thus separating the composite wall structure 3 and the two casting templates 4. This reduces the amount of concrete entering between the composite wall panel 301 and the composite wall back plate 302 when the concrete wall is poured in the two casting templates 4, and avoids affecting the effect of filling the space between the composite wall panel 301 and the composite wall back plate 302 with sound insulation and heat insulation materials. In addition, when constructing two casting templates 4, multiple tie bars 504 are passed through the interior of the two casting templates 4, and multiple pins 502 are inserted into the limiting slots 15 at one end of the multiple tie bars 504 by using the upright plate 501. For the multiple tie bars 504 in the longitudinal direction, multiple upright plates 501 are needed to carry multiple pins 502. The different upright plates 501 are connected by a seven-shaped plate 503 set on one side of the upright plate 501. Meanwhile, the first spring 510 is supported between the side wall of the connecting slot 19 and the side wall of the first storage column slot 1. When the locking block 505 slides down to the positioning slot 14 inside the movable slot 16, the trapezoidal strip 509 extends out from inside the connecting slot 19 and engages with the inside of the positioning slot 14. This restricts the locking block 505 from moving up inside the movable slot 16, making it easier to adjust the bottom of the seven-shaped plate 503 connected to the locking block 505 to contact the top of the vertical plate 501 directly below. Ultimately, when the top vertical plate 501 is struck, the seven-shaped plate 503 controls the vertical plate 501 below to move synchronously, and simultaneously strikes multiple pins 502 to engage with the corresponding position limiting slots 15. Furthermore, by adjusting the threaded connection between the adjusting screw 507 and the seven-shaped plate 503, the control plate 506 pushes the two trapezoidal pressure strips 508 into the interior of the second movable slot 17. With the cooperation of the inclined inner wall of the trapezoidal pressure strip 508 and the inclined side wall of the second movable slot 17, the trapezoidal locking strip 509 is retracted into the serial slot 19, and the first spring 510 is compressed. This allows the locking block 505 to move smoothly inside the movable slot 16, facilitating the subsequent removal of multiple pins 502 from the corresponding limiting slots 15.

[0021] Example 2: Based on Example 1, the embodiment of this application aims to ensure that the isolation plate 7 on one side of the multiple plugs 8 is tightly fitted to the side edge of the composite wall panel 301. The overall concept is as follows: like Figures 1 to 3 , Figures 5 to 7 As shown, a filling assembly 6 is provided between the multiple tension bars 504 and the isolation plate 7 in the longitudinal row. The filling assembly 6 includes two facing strips 601. The top and bottom of the two strips 601 are machined with guide slopes 13. Multiple guide slopes 13 are opened inside the two strips 601. The multiple guide slopes 13 inside the two strips 601 are coaxially arranged. A second spring 602 is provided inside the two guide slopes 13 in the coaxial state. The two strips 601 are symmetrical about the origin. In this way, by making the two strips 601 symmetrical about the origin and supporting the second spring 602 between the two strips 601, when the filling component 6 is installed as a whole between the two casting templates 4, one strip 601 abuts against multiple plugs 8, while the other strip 601 abuts against one side of multiple vertical tie bars 504, so that the isolation plate 7 carrying multiple plugs 8 can be tightly fitted with the composite wall panel 301 and the composite wall back plate 302. Secondly, to prevent the two strips 601 from detaching, such as Figure 6As shown, each of the two strips 601 has multiple second storage slots 12 inside. The multiple second storage slots 12 inside the two strips 601 are coaxially arranged. The two second storage slots 12 in the coaxial state are provided with the same long bolt 603. One end of the long bolt 603 is threadedly connected to a nut 604. By connecting the long bolt 603 between the two strips 601, the strips 601 can be supported to slide outside the long bolt 603, and the two strips 601 can be prevented from detaching from the connection.

[0022] In this embodiment, a filling component 6 consisting of two strips 601 is set between the isolation plate 7 and the casting template 4, and multiple second springs 602 are set between the two strips 601. After multiple locking components 5 are passed through the inside of the two casting templates 4 and fixed, the filling component 6 can be installed as a whole between the two casting templates 4, so that one strip 601 abuts against multiple plugs 8, and the other strip 601 abuts against one side of multiple vertical tie bars 504. This makes it easy for the isolation plate 7 carrying multiple plugs 8 to fit tightly with the composite wall panel 301 and the composite wall back plate 302. This prevents the isolation plate 7 from moving between the composite wall panel 301 and the composite wall back plate 302 when pouring concrete between the two casting templates 4, which would cause a large amount of concrete to enter between the composite wall panel 301 and the composite wall back plate 302 and reduce its internal space.

[0023] Specifically, when using this device to perform operations: First, the prefabricated solid wall structure 2 and composite wall structure 3 are installed on the ground. A steel cage is tied between the solid wall structure 2 and the composite wall structure 3. One end of the transverse steel bar 304 and multiple steel rings 202 on one side of the solid wall 201 are tied and fixed to the steel cage. Then, the isolation plate 7 is fastened to the outside of one end of the multiple horizontal steel bars 304, so that one end of the multiple horizontal steel bars 304 passes through the inside of the plug 8 and the first movable slot 11, keeping the side of the isolation plate 7 in contact with the surface of the composite wall back plate 302, and the side of the composite wall panel 301 in contact with the surface of the isolation plate 7. Next, two casting templates 4 are erected outside the steel cage, sandwiching the solid wall structure 2 and the composite wall structure 3. When multiple tie bars 504 pass through the inside of the two casting templates 4, the vertical plate 501 drives multiple pins 502 to be inserted into the limiting slots 15 at one end of the tie bars 504 respectively. The first spring 510 is supported between the side wall of the connecting slot 19 and the side wall of the first receiving column slot 1. When the locking block 505 slides down to the bottom of the movable slot 16 to the positioning slot 14, the trapezoidal strip 509 extends out from the inside of the connecting slot 19 and is engaged in the positioning slot 14.
