Description

Technical Field

[0001] The present application relates to the field of shear wall casting structures, and in particular to a shear wall vertical formwork joint support structure. Background Art

[0002] Shear walls, also known as wind-resistant walls, earthquake-resistant walls, or structural walls, are the primary structures in buildings or structures that bear the horizontal and vertical loads (gravity) caused by wind or earthquakes, preventing structural shear damage. They are also known as earthquake-resistant walls and are generally made of reinforced concrete.

[0003] Chinese patent publication number CN113775173A discloses a structure for reinforcing the interlayer joints of an outer shear wall. In this patent document, a screw is threadedly connected to a pre-embedded wire thread embedded in the shear wall to secure the joint of the first exterior wall panel. Because the pre-embedded wire thread is cast into the shear wall, it is difficult to remove. The existing practice is to cut away the protruding portion of the pre-embedded wire thread, leaving the remaining pre-embedded wire thread inside the shear wall. Over time, the pre-embedded wire thread or threaded sleeve is prone to rust, causing surface contamination on the shear wall and seriously affecting its aesthetics. Utility Model Content

[0004] In order to improve the problem of rust on embedded wire drawing, resulting in rust stains and pollution on the surface of shear wall, which leads to inconvenience in the use of joint structure, the present application provides a shear wall vertical formwork joint support structure.

[0005] The present application provides a shear wall vertical formwork joint support structure that adopts the following technical solution:

[0006] A shear wall vertical formwork joint support structure includes an inner wall formwork and an outer wall formwork. The outer wall formwork extends to the outer wall surface of the shear wall. A threaded sleeve is pre-embedded in the shear wall. A hot melt layer is provided between the threaded sleeve and the shear wall. The hot melt layer and the threaded sleeve are hot-melt welded. The outer wall formwork and the threaded sleeve are connected by a threaded connector.

[0007] By adopting the above technical solution, when supporting the vertical formwork of the shear wall, the threaded connector is screwed into the threaded sleeve, and the external wall formwork located on the side of the shear wall is pressed against the side of the shear wall to complete the joint setting of the formwork; the threaded connector is screwed out of the threaded sleeve to realize the disassembly of the external wall formwork and the shear wall, and then the threaded sleeve is heated, and the hot melt layer is melted by the heat, which facilitates the disassembly of the threaded sleeve from the shear wall. By disassembling the threaded sleeve, the rust caused by the rust of the threaded sleeve is prevented from contaminating the surface of the shear wall, thereby improving the aesthetics of the shear wall.

[0008] In a specific embodiment, a first protrusion embedded in the shear wall is fixedly provided on the hot melt layer.

[0009] By adopting the above technical solution and utilizing the first protrusion, the firmness of the connection between the hot melt layer and the shear wall is improved.

[0010] In a specific embodiment, the threaded sleeve is fixedly provided with a second protrusion embedded in the hot-melt layer.

[0011] By adopting the above technical solution and utilizing the second protrusion, the firmness of the connection between the threaded sleeve and the hot melt layer is improved.

[0012] In a specific possible implementation scheme, the exterior wall formwork includes a first plate body opposite to the interior wall formwork and a second plate body attached to the outer side of the shear wall, and the first plate body and the second plate body are detachably connected by bolts.

[0013] By adopting the above technical solution, the exterior wall formwork is configured to be composed of a first plate body and a second plate body spliced together by bolts. During disassembly, the exterior wall formwork can be disassembled into the first plate body and the second plate body to reduce the volume of the exterior wall formwork and facilitate the transportation of the exterior wall formwork.

[0014] In a specific possible implementation manner, the connecting surfaces of the first plate body and the second plate body are both stepped surfaces.

[0015] By adopting the above technical solution and utilizing the setting of the stepped surface, the contact surface between the first plate and the second plate is increased, thereby improving the stability of the connection between the first plate and the second plate.

[0016] In a specific possible implementation scheme, the threaded connection includes a connecting bolt and a clamping member, and the clamping member is arranged on the second plate body. The connecting bolt passes through the clamping member and the second plate body, and is threadedly inserted into the threaded sleeve so that the second plate body can be pressed against the shear wall through the clamping member.

[0017] By adopting the above technical solution, when connecting the second plate body and the shear wall, the connecting bolts are passed through the clamping piece and the second plate body in sequence, and then screwed into the threaded sleeve, and the connecting bolts are continued to be screwed. The connecting bolts press the second plate body against the shear wall through the clamping piece, thereby completing the installation and fixation of the second plate body; effectively avoiding the occurrence of slurry flow, misalignment, honeycomb and other phenomena in the construction joints of the upper and lower layers of the shear wall.

[0018] In a specific possible implementation scheme, the clamping member includes a clamping plate and two clamping rods, the connecting bolt is passed through the clamping plate, the two clamping rods are arranged perpendicular to the connecting bolt and are located on both sides of the connecting bolt, and the head of the connecting bolt can squeeze the clamping plate so as to clamp and fix the two clamping rods on the second plate.

[0019] By adopting the above technical solution, the connecting bolts press the two pressing rods onto the second plate through the pressing sheet, so that the extrusion force applied by the connecting bolts to the second plate is more uniform, thereby improving the sealing of the contact between the second plate and the shear wall.

[0020] In a specific possible implementation scheme, the first plate body and the inner wall formwork are both provided with a tension screw, and two sets of fixing nuts are threadedly sleeved on the tension screw, and the inner wall formwork and the first plate body are both located between the two sets of fixing nuts.

[0021] By adopting the above technical solution, the fixing nut is screwed to the first plate body and abutted against the inner wall formwork, thereby improving the connection stability between the first plate body and the inner wall formwork.

[0022] In a specific possible implementation scheme, a water-stop support plate is provided between the fixing nut and the first plate body and the inner wall formwork.

[0023] By adopting the above technical solution and utilizing the setting of the water-stop support plate, on the one hand, water leakage in the gap between the through screw and the first plate body or the inner wall formwork can be reduced, and on the other hand, the uniformity of the force between the fixing nut and the first plate body or the inner wall formwork can be improved.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Screw the threaded connector out of the threaded sleeve to disassemble the exterior wall formwork and the shear wall. Then heat the threaded sleeve to melt the hot melt layer, making it easier to disassemble the threaded sleeve from the shear wall. By disassembling the threaded sleeve, the rust on the threaded sleeve is prevented from contaminating the shear wall surface, thereby improving the aesthetics of the shear wall.

[0026] 2. The exterior wall formwork is configured to be composed of a first plate body and a second plate body joined together by bolts. When disassembling, the exterior wall formwork can be disassembled into the first plate body and the second plate body to reduce the volume of the exterior wall formwork and facilitate transportation of the exterior wall formwork.

[0029] The following is combined with Figure 1 This application is described in further detail.

[0030] An embodiment of the present application discloses a shear wall vertical formwork joint support structure.

[0031] Reference Figure 1 A shear wall vertical formwork joint support structure includes an inner wall formwork 21 and an outer wall formwork 22. The inner wall formwork 21 is overlapped on the shear wall 1 of the lower layer. The outer wall formwork 22 includes a first plate body 221 opposite to the inner wall formwork 21 and a second plate body 222 attached to the outer surface of the shear wall 1. The second plate body 222 and the first plate body 221 are detachably connected by bolts 223.

[0032] Reference Figure 1 A threaded sleeve 3 is embedded in the shear wall 1. A hot melt layer 4 is provided between the threaded sleeve 3 and the shear wall 1. In this embodiment, the hot melt layer 4 is a plastic layer and is provided along the circumference of the threaded sleeve 3. The hot melt layer 4 and the threaded sleeve 3 are welded by hot melt. The exterior wall formwork 22 is connected to the threaded sleeve 3 via a threaded connector 5. When heating the threaded sleeve 3, electric heating can be used.

[0033] When supporting the vertical formwork of the shear wall 1, first connect the first plate 221 and the second plate 222 with the bolts 223 to form the exterior wall formwork 22. Then, screw the threaded connector 5 into the threaded sleeve 3, and press the second formwork located on the side of the shear wall 1 against the side of the shear wall 1 to complete the template joint setting. Screw the threaded connector 5 out of the threaded sleeve 3 to disassemble the exterior wall formwork 22 from the shear wall 1. Then, heat the threaded sleeve 3, and the hot melt layer 4 melts due to the heat, making it easier to disassemble the threaded sleeve 3 from the shear wall 1. By disassembling the threaded sleeve 3, it is prevented that the rust caused by the rust of the threaded sleeve 3 will contaminate the surface of the shear wall 1, thereby improving the aesthetics of the shear wall 1.

[0034] Reference Figure 1 The outer peripheral sidewall of the hot melt layer 4 is fixedly provided with a first protrusion 41 that is embedded in the shear wall 1. The first protrusion 41 is integrally formed with the hot melt layer 4. The first protrusion 41 enhances the secure connection between the hot melt layer 4 and the shear wall 1. The threaded sleeve 3 is fixedly provided with a second protrusion 31 that is embedded in the hot melt layer 4. Multiple second protrusions 31 are provided along the circumference of the threaded sleeve 3 to enhance the secure connection between the threaded sleeve 3 and the hot melt layer 4.

[0035] Reference Figure 1The first plate 221 and the second plate 222 are each provided with a stepped surface 224 on their opposing sides. The provision of the stepped surface 224 creates a stepped structure at the opposing ends of the first plate 221 and the second plate 222. The exterior wall formwork 22 is configured such that the first plate 221 and the second plate 222 are joined together by bolts 223. During disassembly, the exterior wall formwork 22 can be disassembled into the first plate 221 and the second plate 222, thereby reducing the volume of the exterior wall formwork 22 and facilitating its transport. The provision of the stepped surface 224 increases the contact surface between the first plate 221 and the second plate 222, thereby improving the stability of the connection between the first plate 221 and the second plate 222.

[0036] Reference Figure 1 The threaded connector 5 in this embodiment includes a connecting bolt 51 and a pressing member 52. The pressing member 52 in this embodiment includes a pressing piece 521 and two pressing rods 522. The pressing piece 521 is an arc-shaped piece with an opening facing the second plate 222. The pressing rods 522 are both hollow steel tubes. The two pressing rods 522 are arranged perpendicular to the connecting bolt 51 and are located on both sides of the connecting bolt 51. The pressing piece 521 has an arc-shaped groove that fits the pressing rods 522. When the second plate 222 is compressed and fixed, the connecting bolt 51 passes through the pressing piece 521 and the second plate 222 in sequence and is threaded into the threaded sleeve 3. The head of the connecting bolt 51 presses the pressing piece 521 and the pressing rods 522 to press the second plate 222 against the shear wall 1.

[0037] When connecting the second plate 222 to the shear wall 1, the connecting bolt 51 presses the two pressing rods 522 onto the second plate 222 through the pressing piece 521, and then screws into the threaded sleeve 3. The connecting bolt 51 is further screwed, and the connecting bolt 51 presses the second plate 222 onto the shear wall 1, thereby completing the installation and fixation of the second plate 222, effectively avoiding the occurrence of slurry flow, misalignment, honeycombing, etc. in the construction joints of the upper and lower layers of the shear wall 1. The two pressing rods 522 are pressed onto the second plate 222 by the pressing piece 521, so that the extrusion force applied by the connecting bolt 51 to the second plate 222 is more uniform, thereby improving the sealing of the contact between the second plate 222 and the shear wall 1.

[0038] Reference Figure 1The first plate 221 and the interior wall formwork 21 are both provided with a tensioning screw 61. Two sets of fixing nuts 62 are threaded onto the tensioning screw 61. Each set of fixing nuts 62 has one fixing nut 62. The interior wall formwork 21 and the first plate 221 are both located between the two fixing nuts 62. Waterstop support plates 63 are provided between the fixing nuts 62 and the first plate 221 and the interior wall formwork 21. The fixing nuts 62 abut the waterstop support plates 63 against the first plate 221. The fixing nuts 62 are screwed onto the first plate 221 and abut the interior wall formwork 21, improving the connection stability between the first plate 221 and the interior wall formwork 21. The provision of the waterstop support plates 63 can, on the one hand, reduce water leakage through the gap between the tensioning screw and the first plate 221 or the interior wall formwork 21, and on the other hand, improve the uniformity of the force between the fixing nuts 62 and the first plate 221 or the interior wall formwork 21.

[0039] The implementation principle of the vertical formwork joint support structure of a shear wall in an embodiment of the present application is: when the threaded sleeve 3 is disassembled, the threaded sleeve 3 is heated, and the hot melt layer 4 is melted by the heat, which facilitates the disassembly of the threaded sleeve 3 from the shear wall 1. By disassembling the threaded sleeve 3, the rust caused by the rust of the threaded sleeve 3 is prevented from contaminating the surface of the shear wall 1, thereby improving the aesthetics of the shear wall 1.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
