Description

Technical Field

[0001] The utility model belongs to the technical field of thermal insulation buildings, and particularly relates to a combination part for connection and tensioning and a composite thermal insulation wall structure. Background Art

[0002] In recent years, the concepts of "green building" and "energy conservation and emission reduction" have been gradually deepened in building design, and new materials and new technologies for wall thermal insulation have emerged continuously. At present, the exterior walls constructed by integral thermal insulation mainly use ordinary screws for reinforcement. The thermal insulation board acts as one side formwork. After combining the thermal insulation board and the shear wall with screws, concrete is poured to form a thermal insulation wall, which has been widely applied in actual construction. The main advantage is that the thermal insulation building is formed at one time, saving the construction period and labor costs of subsequent thermal insulation construction.

[0003] In the prior art, there is still room for improvement in the screws used for combining the thermal insulation board and the shear wall. For example, in a thermal insulation structure integration system based on a high-precision formwork with the patent authorization number CN220978473U, the non-removable tie rod used in it protrudes from both sides of the wall as a whole after the construction is completed. After removing its tension bolt, water seepage is likely to occur in the tension bolt holes; and the certain pressure generated when the tension bolt is clamped is applied to the thermal insulation board and the two side formworks, which is likely to cause damage or deformation to them, affecting subsequent construction and thermal insulation performance.

[0031] The following will describe the present utility model in detail in conjunction with the specific embodiments shown in the drawings. However, these embodiments do not limit the present utility model, and any structural, method, or functional transformation made by those of ordinary skill in the art based on these embodiments is included in the protection scope of the present utility model.

[0032] As Figure 1-2 shown, this embodiment proposes a combination member a that plays a connecting and tensioning role, including a non-removable tie rod 5. The non-removable tie rod 5 is provided with external threads at least at both ends. In some embodiments, external threads can also be provided throughout the non-removable tie rod 5. Two external threads are respectively thread-connected with nuts 6. A pin hole 64 is formed in the nut 6, and a clamping member 7 is also sleeved on the nut 6; it also includes a pin piece 8, and the pin piece 8 can be inserted into the pin hole 64 to position the clamping member 7 on the nut 6.

[0033] During the actual construction process, after the non-removable tie rod 5 is inserted into the composite insulation wall, nuts are installed on both sides respectively. The clamping member 7 is inserted on the nut 6, and then the pin piece 8 is inserted into the pin hole 64 to position the clamping member 7 on the nut 6, which can realize the quick installation and positioning of the clamping member 7; through this structure, the two clamping members 7 can be centered and tightened, realizing the tight connection between internal components, and avoiding deformation or movement of the composite insulation wall due to the pressure of concrete during the pouring process; in this design, the nut 6 is connected to the non-removable tie rod 5, and the clamping member 7 is positioned by using the nut 6. After the construction is completed, the nut 6 and the clamping member 7 can be directly disassembled. After disassembly, both ends of the non-removable tie rod 5 are hidden in the concrete or formwork 3, and are filled with special composite slurry to avoid cold bridges and play a certain role in waterproofing and anti-seepage, improving energy efficiency and living comfort, and at the same time maintaining a certain aesthetic appearance.

[0034] A built-in clamping plate member 9 is detachably connected in one of the threaded sections, and a part of the nut 9 is located between the external threaded section 51 and the built-in clamping plate member 9:

[0035] In some embodiments, a snap ring 52 is fixedly connected to the inner side of one of the external threaded sections 51. The built-in clamping plate member 9 is detachably inserted into the snap ring 52. When the built-in clamping plate member 9 is inserted at one end of the non-removable tie rod 5, a part of the nut 6 is located between the external threaded section 51 and the built-in clamping plate member 9; in this design, the built-in clamping plate member 9 is placed in the insulation board 1. When the clamping member 7 is centered and tightened, it will bring a certain pressure to the insulation board 1, and the built-in clamping plate member 9 is used to bear this pressure, thereby avoiding directly damaging the insulation board 1 and affecting its insulation performance;

[0036] Further, the built-in card board member 9 includes a plug ring 91. The snap ring 52 is a slope-shaped annular structure and is made of an elastic material. The plug ring 91 is used to plug into the inner side of the snap ring 52 from the outside to fix the entire built-in card board member 9. The outer end of the plug ring 91 is fixed with a built-in cylinder 92, and the outer end of the built-in cylinder 92 is fixedly connected with a support disk 93. The support disk 93 is in the shape of a flared opening, and its outer side is on the same plane as the heat preservation board 1. In this design, the quick installation is realized by the insertion connection of the plug ring 91 and the snap ring 52. It is easy to operate during the construction process, saving a large amount of installation time. After installation, the built-in card board member 9 is prevented from popping out by the snap ring 52, ensuring the stability of the installation. The support disk 93 is in the shape of a flared opening, which can evenly distribute the pressure and avoid causing certain damage to the heat preservation board 1.

[0037] In some embodiments, a built-in card board member 9 is threadedly connected to one of the external thread segments 51. Further, the built-in card board member 9 includes a built-in cylinder 92 that can be threadedly connected to one of the external thread segments 51. The outer end of the built-in cylinder 92 is fixedly connected with a support disk 93. In this embodiment, another detachable connection method is provided. Compared with the above detachable connection through the snap ring 52, the step of further processing on the non-removable tie rod 5 is omitted, saving a certain amount of cost.

[0038] In some embodiments, the nut 6 includes a cylinder body 61. The cylinder body 61 is in a frustum shape, which is convenient for subsequent disassembly. The cylinder body 61 has an internal thread segment 62 that can be threadedly connected to the external thread segment 51 at the end of the non-removable tie rod 5. The outer end of the cylinder body 61 is fixed with a plug post 63. The cross section of the plug post 63 is hexagonal or rectangular, which is convenient to be disassembled by a special tool after use. A pin hole 64 as described above is provided on the side plane of the plug post 63. During installation, the nut 6 is directly threadedly connected to the non-removable tie rod 5. This operation is quick and convenient. The cross section of the plug post 63 is in a rounded rectangular shape or a rectangular shape. In this structure, the plug post 63 has two side planes. When the clamping member 7 is inserted into the plug post 63, the rounded rectangular shape or the rectangular shape can prevent the clamping member 7 from rotating or moving when inserted into the plug post 63, ensuring the stability of the clamping member 7 after being inserted into the plug post 63.

[0039] In some embodiments, the clamping member 7 includes a connecting portion 71. A through hole 72 is provided on the connecting portion 71 and is adapted to be inserted into the plug post 63 in the nut 6. The upper and lower ends of the connecting portion 71 are respectively fixedly connected with arc-shaped holding arms 73. The connecting portion 71 and the two arc-shaped holding arms 73 are of an integral structure. During the construction process, there are two arc-shaped spaces between the two arc-shaped holding arms 73 and the heat preservation board 1. These arc-shaped spaces can be used to prevent the square timber 4, avoiding the clamping member 7 directly contacting the heat preservation board 1 or the template 3 and causing damage to them.

[0040] In some embodiments, the pin piece 8 is in the shape of a right trapezoid or a triangle, and the inclined side of the pin piece 8 is in a stepped or serrated structure, which can increase the friction force between the pin hole 64 and the clamping member 7, thereby improving the connection stability. At the same time, it can engage with both to provide a certain locking effect.

[0041] As Figure 3-4 shown, the present utility model also provides a composite insulation wall structure, which includes a shear wall 2, with a thermal insulation board 1 and a formwork 3 respectively arranged on both sides of the shear wall 2; it also includes any one of the above-mentioned combination members a that play a connecting and tensioning role;

[0042] Among them, the non-removable tie rod 5 only penetrates through the shear wall 2, the thermal insulation board 1 and the formwork 3, and an internal clamping plate member 9 is embedded outside the thermal insulation board 1. Two nuts 6 are respectively threadedly connected to both ends of the non-removable tie rod 5. A part of one of the nuts 6 is placed inside the internal clamping plate member 9. Two clamping members 7 are respectively inserted onto the nuts 6. A wooden square 4 is arranged between the clamping member 7 and the formwork 3 or the thermal insulation board 1. Two pin pieces 8 are respectively inserted into the outer ends of the pin holes 64 to center and clamp the two clamping members 7.

[0043] During the construction process, the shear wall 2, the thermal insulation board 1 and the formwork 3 are pre-connected tightly together, and holes are reserved or drilled on-site inside them. The non-removable tie rod 5 is placed in the holes. The internal clamping plate member 9 is clamped to the right side of the non-removable tie rod 5. Subsequently, nuts 6 are threadedly connected to both ends of the non-removable tie rod 5. The two clamping members 7 are respectively inserted into the nuts 6. A wooden square 4 is placed between the two clamping members 7 and the formwork 3 to prevent the clamping member 7 from directly applying pressure to the formwork 3 and causing damage to the thermal insulation board 1. The two clamping members 7 are centered and clamped by the pin pieces 8, so that the wooden square 4, the shear wall 2, the thermal insulation board 1 and the formwork 3 inside are clamped and positioned to prevent them from shifting during the subsequent construction process. After clamping, the subsequent construction can be carried out. After the construction is completed, the wooden square 4, the pin pieces 8, the clamping members 7 and the nuts 6 can be taken out and reused. The non-removable tie rod 5 is placed inside to form an integrated structure in a hidden manner, eliminating the problems of heat bridges and water seepage in the traditional tensioning nut holes.
