[0035] Step 3: Install the fixed connection piece: insert the screw sleeve of the fixed connection piece into the pit and rotate it together with the first screw rod;

[0036] Step 4: Install the mounting assembly.

[0037] In the description of the present invention, the "support member" and "pull rod" can be round, square or sheet-shaped, etc., and their shapes are not limited. Their materials can be metal, plastic, etc., and their materials are not limited.

[0038] In the description of the present invention, the "outer cap" is cylindrical, which means that the inner and outer dimensions are the same and there are no steps, and the "conical" means that its edge can be a straight edge, an outer convex arc or an inner concave arc, etc. The purpose is to facilitate the removal of the positioning cap and reduce or remove the damage caused by the positioning cap to the concrete layer that has not been completely set.

[0039] In the present invention, the support positioning member is used to support and position the inner and outer formwork during the wall prefabrication or on-site construction process, and can be used as a fixing anchor or a tension bolt, which cooperates with the tension rod to lock the inner and outer formwork. After the wall is completed and usually before the concrete is completely set, the positioning cap is unscrewed and a pit is formed on the surface of the concrete. The fixed connector is used to extend into the pit and connect with the first screw rod, and the hanging assembly is used to connect the fixed connector and the hanging plate. The hanging plate can be a thermal insulation decorative plate, a stone plate or an aluminum alloy decorative plate.

[0040] The present invention may have one of the beneficial effects:

[0041] (1) The present invention uses supporting fixtures as the basis for connecting the hanging plates, and does not need to drill holes in the wall to bury additional connecting parts, which not only increases the firmness of the connecting hanging plates, but also reduces the construction process and improves the construction efficiency;

[0042] (2) No wet operation, no pollution, meeting the requirements of green buildings;

[0043] (3) The embedded parts in the prior art need to extend out of the wall, which is not easy to be waterproof and anti-corrosion, and has poor durability and safety. The present invention can fill the pit with foamed polyurethane to achieve waterproof and anti-corrosion effects on the supporting positioning parts;

[0044] (4) The length of the fixed connector can be set to various specifications. When installing the hanging components, fixed connectors of different specifications and sizes can be selected according to the degree of incompleteness of the wall, thereby achieving mortar-free and leveling-free. After the exterior wall is demoulded, it can be directly installed and used without any treatment;

[0045] (5) Fully assembled installation: after the wall is cast using super-flat formwork, it can be installed using fixed connectors and hanging components;

[0046] (6) Environmentally friendly exterior wall painting. The panels can be painted in the factory, eliminating the environmental pollution caused by on-site painting. In particular, on-site painting of the upper part of high-rise buildings can easily cause large-scale pollution to the surrounding environment. In addition, there is no cutting or drilling at the construction site, so there is no dust pollution.

[0047] (7) The exterior wall has diversified shapes. The exterior of the cast-in-place wall structure can be directly hung with panels without secondary treatment, and complex shapes can be designed for prefabricated installation.

[0048] (8) Adapt to different insulation standards and different types of walls, that is, use different types of support positioning parts and hanging panels to achieve flexible application of various combinations, adapt to different energy-saving standards, from energy-saving 65% energy-saving standards to near-zero energy consumption buildings.

[0095] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar components or components having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0096] Example 1 Wall and hanging plate bolt assembly

[0097] like Figure 1-7 As shown, the wall and hanging plate bolting assembly includes a supporting positioning member 1, a pulling rod 13, a fixed connecting member 2 and a hanging assembly 3.

[0098] (1) Supporting and positioning member 1

[0099] like Figure 1-3 As shown, the support positioning member 1 includes a support member 11 and a positioning cap 12. The support member 11 is rod-shaped, and at least one end of the support member 11 forms a first screw rod 111. The axis of the positioning cap 12 is provided with a threaded hole 121 that matches the first screw rod 111. When the first screw rod 111 is screwed into the threaded hole 121, the end face of the first screw rod 111 is located in the middle of the threaded hole 121. The positioning cap 12 is cylindrical or tapered from the outer end to the inner end. A stop is formed on the inner side of the first screw rod 111 to limit the maximum screwing degree of the positioning cap 12.

[0100] The positioning cap 12 includes an internal nut 122 and an outer cap 123 connected to the outside of the nut 122. The axis of the nut 122 is provided with a threaded hole 121 that matches the first screw rod 111. The outer cap 123 is cylindrical or tapered from the outer end to the inner end, so as to form a smooth surface on the outer side of the outer cap 123, so as to avoid or reduce damage to the concrete layer that has not been completely set when the positioning cap 12 is unscrewed from the first screw rod 111.

[0101] The outer cap 123 is made of elastic material, and the outer edge of the outer cap 123 exceeds the outer edge of the nut 122. In this way, when the positioning cap 12 is pressed against the high-precision template, the high-precision template is pressed against the outer edge of the nut 122 under the extrusion, and the outer cap 123 is deformed under the extrusion to achieve a tight seal to ensure that there is no leakage. Advantageously, a gap 124 is left between the outer side of the outer cap 123 and the outer side of the nut 122, so that the outer side of the nut 122 is exposed, so that the outer side of the outer cap 123 forms a "cantilever" structure, which is convenient for using a socket wrench to disassemble the positioning cap 12 on the one hand, and makes the outer side of the outer cap 123 more easily deformed by extrusion, forming a "leather cup" type sealing effect.

[0102] A water stopper 112 is provided on the support member 11 . Advantageously, the water stopper 112 is in sheet shape and fixedly connected to the support member 11 .

[0103] The support member 11 is also provided with one or more of the following positioning members: structural steel bar positioning members (such as shear wall steel bar positioning members), steel mesh positioning members, insulation board inner positioning members and insulation board outer positioning members, so as to adapt to built-in insulation shear walls, built-in insulation filling walls or no built-in insulation shear walls or no built-in insulation filling walls.

[0104] The support member 11 is a one-stage structure or a multi-stage structure. The one-stage structure uses a metal rod or a plastic rod, which is a conventional tension screw. The multi-stage structure includes a first rod segment in the middle and a second rod segment connecting the two ends of the first rod segment. The first rod segment is an injection molded part, which is used for cold and hot broken bridges and is a broken bridge tension screw. Advantageously, the first rod segment and the second rod segment are connected by threads or barbs, and the barbs are used to form an integral connection and cannot be disassembled.

[0105] (2) Pull rod 13

[0106] like Figure 4 , 5 As shown, the tie rod 13 is used to connect to the first screw rod 111. The inner side of the tie rod 13 is provided with an inner threaded end 131, and the inner threaded end 131 cooperates with the positioning cap 12. The outer side of the tie rod 13 is provided with a locking member for locking the inner template and / or the outer template.

[0107] In a specific example, the locking structure is an outer threaded end provided on the outer side of the tie rod 13, and the locking member is a locking nut 132, which is matched with the outer threaded end. The locking nut 132 can be a mountain-shaped nut.

[0108] Another specific example is that the locking structure is a locking pin hole provided on the outside of the tension rod 13, the locking member is a locking pin piece 133, and the locking pin piece 133 has an inclined surface.

[0109] Advantageously, after the inner threaded end 131 is screwed into the nut 122 , it contacts the end surface of the first screw rod 111 of the support member 11 , thereby more firmly fixing the tie rod 13 to the support member 11 .

[0110] (3)Fixed connector 2

[0111] In a specific example, the fixed connection member 2 may also be referred to as a "vertical keel fixing screw sleeve specifically for tension bolts".

[0112] like Figure 6 , 7 As shown, the fixed connection member 2 includes a fixing member body 21 , one end of which has a threaded sleeve 22 matched with the first screw rod 111 , and the other end forms a second screw rod 23 , on which a first fixing nut 24 is applied.

[0113] A plugging piece whose size is larger than the positioning cap 12 is provided on the fixed connector 2 near one end of the screw sleeve 22. When the screw sleeve 22 is screwed on the first screw rod 111, the plugging piece fits the plane at the outer edge of the positioning cap 12. The plugging piece is used for sealing and waterproofing. Specifically, the plugging piece includes a plugging platform 25 and a first gasket 26 sleeved on the screw sleeve 22. The plugging platform 25 is integrally connected to the fixed connector 2 and has a bolt head structure, which facilitates the processing of the fixed connector 2. Advantageously, the first gasket 26 is a spring gasket, which plays a prestressed locking role in the threaded connection between the screw sleeve 22 and the first screw rod 111, and also has a preventive effect.

[0114] To facilitate fixing the hanging assembly 3, a second fixing nut 27 is further provided on the second screw rod 23. After assembly, the hanging assembly 3 is arranged between the first fixing nut 24 and the second fixing nut 27. A second gasket 28 is provided on the inner side of the second fixing nut 27. After assembly, the second gasket 28 is located between the second fixing nut 27 and the hanging assembly 3.

[0115] In order to prevent the hanging plate 4 from loosening during vibration or swinging, one or all of the following methods may be used: the first fixing nut 24 is a locking nut, and an elastic sleeve 29 is provided on the inner side of the second fixing nut 27, and the elastic sleeve 29 applies an outward elastic force to the second fixing nut 27. Optionally, the elastic sleeve 29 is an elastic polyurethane sleeve.

[0116] In order to achieve the mortar-free leveling effect, the fixed connector 2 can be set in a variety of different length specifications. During the assembly process, fixed connectors 2 of different length specifications are selected according to the flatness deviation of the wall 5, so that the hanging component 3 can be placed on a plane, thereby ensuring that the hanging plate 4 is on a plane.

[0117] (4) Hooking assembly 3

[0118] The inner side of the hanging component 3 is used to be connected to the fixed connecting member 2 , and the outer side is used to hang the hanging plate 4 .

[0119] As a specific example, the mounting component 3 includes:

[0120] A hanging bracket 31, the hanging bracket 31 includes a vertical bracket and a horizontal bracket, and the vertical bracket and / or the horizontal bracket are connected to the fixed connection member 2;

[0121] A first hanging member, the first hanging member is arranged on the vertical bracket or the horizontal bracket;

[0122] The second hanging member is used to connect the hanging plate 4, and the second hanging member matches the first hanging member.

[0123] As a further example, the first mounting member is installed in one of the following ways:

[0124] Back hanging: the horizontal support is a back hanging beam 312, the vertical support is a vertical keel 311, the back hanging beam 312 is installed between two adjacent vertical keels 311, the back hanging beam 312 is bent to form a first hanging member or the back hanging beam 312 is connected to the first hanging member;

[0125] Bolting: the vertical support is a vertical keel 311, the horizontal support is a horizontal angle steel 313, adjacent horizontal angle steels 313 are connected with back bolts 314, the back bolts 314 are provided with a first hanging member, and the back bolts 314 are provided with an adjusting nut 315 to fix the first hanging member; or

[0126] Pin hanging: the vertical support is a vertical keel 311, the horizontal support is a pin rod 333, and the pin rod 333 forms a first hanging member.

[0127] Optionally, a fixed support plate 341 is further provided on the hanging bracket 31 , and at least one hanging bracket is provided at the end of the fixed support plate 341 extending forward.

[0128] Example 2 Wall and hanging board bolting system

[0129] The wall and hanging plate bolting system can be connected by the wall and hanging plate bolting assembly described in Example 1. Specifically, it includes a wall 5, a supporting positioning member 1 embedded in the wall 5, a fixed connection member 2 and a hanging assembly 3.

[0130] Among them, at least one end of the support member 11 extends to the edge of the wall 5 or extends to the edge close to the wall 5, and the end has a first screw 111, and the wall 5 around the first screw 111 forms a pit. In this embodiment, the first screw 111 can extend to the middle or edge of the positioning cap 12, as long as it does not exceed the surface of the wall 5, it belongs to the protection scope of the wall 5 and the hanging plate 4 bolt connection system of this patent. The screw sleeve 22 of the fixed connector 2 extends into the pit and is matched with the first screw 111 for connection.

[0131] The wall 5 can be a built-in insulation shear wall, a built-in insulation filling wall, a shear wall without built-in insulation, or a wall without built-in insulation filling. The hanging board 4 is an insulation decorative board, a stone, or an aluminum alloy decorative board. The cavity between the pit and / or the wall 5 and the hanging board 4 is filled with foamed polyurethane. The foamed polyurethane expands in the pit and densely fills the pit. In addition, the first gasket 26 has a water-blocking effect. Moreover, the foamed polyurethane is also filled between the hanging board 4 and the base wall, which further plays a waterproof and anti-corrosion role.

[0132] The other components and matching relationships of this embodiment are the same as those of embodiment 1.

[0133] Regarding the hanging assembly 3 , for further description, the hanging assembly 3 of the present invention is one or a combination of the following three hanging modes: a back hanging assembly 32 , a pin hanging assembly 33 , and a supporting hanging assembly 34 .
