Description

Technical Field

[0001] This utility model relates to the field of wall formwork reinforcement technology, specifically to an external wall through-wall tie bolt. Background Technology

[0002] In the construction of exterior walls and shear walls, tie bolts are commonly used to reinforce wall formwork. The through-wall bolts left after shear wall formwork reinforcement must be treated. Traditional methods of installing through-wall tie bolts involve cutting off the protruding ends of the bolts and then filling and smoothing mortar into the bolt holes with a trowel. This method embeds disposable tie bolts into the wall, making them unusable and resulting in material waste. Therefore, this invention provides a reusable through-wall tie bolt device. Utility Model Content

[0003] To address the problem that traditional through-wall tie bolts cannot be reused, this utility model provides an external wall through-wall tie bolt.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An external wall through-wall tie bolt, comprising:

[0006] A through-wall sleeve is provided between two templates. At least one water-stop section is provided on the side of the through-wall sleeve, and an annular notch is provided in the middle of the water-stop section.

[0007] A pull-pull assembly, wherein the pull-pull screw of the pull-pull assembly is located inside the through-wall sleeve;

[0008] The annular notch has a teardrop-shaped cross-section, and the inner side of the annular notch is lower than the inner wall of the through-wall sleeve.

[0009] As a further description of the above technical solution:

[0010] The wall sleeve has at least two water-stop sections on its side, and two of the water-stop sections are located near both ends of the wall sleeve.

[0011] As a further description of the above technical solution:

[0012] Both ends of the through-wall sleeve can be detachably and fixedly installed with a trumpet-shaped detachable waterstop, which is located between the two templates.

[0013] As a further description of the above technical solution:

[0014] The horn-shaped detachable waterstop joint includes: an integrally formed horn part and a connecting part, the connecting part being located at the small diameter end of the horn part, and an inner support member being fixedly provided on the inner side of the horn part. The number of inner support members is set to multiple, and the multiple inner support members are distributed in a ring array.

[0015] As a further description of the above technical solution:

[0016] The connecting part is threaded to the end of the through-wall sleeve.

[0017] As a further description of the above technical solution:

[0018] A grip pad and a pull handle are fitted on the pull screw and located on the outside of the template. A nut is threaded onto the pull screw and located on the outside of the pull handle.

[0019] As a further description of the above technical solution:

[0020] The through-wall sleeve is made of PVC, and the flared detachable waterstop is made of stainless steel.

[0021] The beneficial effects of this utility model are:

[0022] This invention, by setting a through-wall sleeve between two templates, allows the tie rod of the tie assembly to be located inside the through-wall sleeve. When pouring concrete, the concrete will not come into contact with the tie rod of the tie assembly. After disassembly, the tie assembly can be reused, thereby saving material costs.

[0023] This invention features at least one water-stop section on the side of the wall sleeve. This water-stop section effectively isolates water (by preventing water from flowing along the side of the wall sleeve). The water-stop section has an annular notch in the center, dividing it into two water-stopping parts, further enhancing the water-blocking effect. The annular notch has a teardrop-shaped cross-section, and its inner side is lower than the inner wall of the wall sleeve. Due to the small area of ​​the outer opening of the annular notch, larger concrete particles do not enter the inner side of the annular notch, while finer concrete particles do, forming a dense concrete layer that further improves the water-blocking effect.

[0032] Please refer to the attached document. Figure 1 - Figure 5 This application illustrates an external wall through-wall tie rod provided in an embodiment of the present application, used to reinforce wall formwork during the construction of external walls and shear walls. Specifically, it includes: a through-wall sleeve 1 and a tie rod assembly. The through-wall sleeve 1 is positioned between two formwork panels. Through the design of the through-wall sleeve 1, the tie rod 5 of the tie rod assembly is located inside the through-wall sleeve 1. During concrete pouring, the concrete will not contact the tie rod 5 of the tie rod assembly. After disassembly, the tie rod assembly can be reused, thereby saving material costs. Furthermore, to ensure the waterproof performance of the concrete wall later, at least one water-stop section 1a is provided on the side of the through-wall sleeve 1. The water-stop section 1a can isolate water (by preventing water from flowing along the side of the through-wall sleeve 1). An annular notch 1b is provided in the middle, which divides the water-stop section 1a into two water-stopping parts, thereby further improving the water-blocking effect. The cross-sectional shape of the annular notch 1b is teardrop-shaped, and the inner side of the annular notch 1b is lower than the inner wall of the through-wall sleeve 1. Because the area of ​​the outer opening of the annular notch 1b is small, larger concrete particles will not enter the inner side of the annular notch 1b. Fine concrete enters the inner side of the annular notch 1b, forming dense concrete, which further improves the water-blocking effect. Furthermore, when filling concrete is injected into the through-wall sleeve 1 later, the concrete, together with the water-stop section 1a and the part inside the annular notch 1b, also form a water-stopping structure, thereby ensuring the waterproof performance of the concrete wall in later use.

[0033] In one embodiment, at least two water-stop sections 1a are provided on the side of the through-wall sleeve 1, and two of the water-stop sections 1a are distributed near both ends of the through-wall sleeve 1.

[0034] The number of waterstop joints 1a designed is generally related to the thickness of the wall. The thicker the wall, the more waterstop joints 1a are designed (the length of the through-wall sleeve 1 is customized according to the thickness of the wall and is cut to a standard length in the factory / on-site).

[0035] In one embodiment, both ends of the through-wall sleeve 1 are detachably and fixedly equipped with a flared detachable waterstop 2. The flared detachable waterstop 2 is located between the two templates. The flared detachable waterstop 2 is used to increase the waterproofness at both ends of the through-wall sleeve 1 and to prevent insufficient contact between the two ends of the through-wall sleeve 1 and the template during the pouring process, so that liquid can enter the interior of the through-wall sleeve 1 and affect the subsequent disassembly of the tie rod assembly.

[0036] Generally, the through-wall sleeve 1 is made of PVC, the flared detachable water-stop joint 2 is made of stainless steel, and the tie rod assembly is made of conventional metal. The through-wall sleeve 1 is for single use, while the flared detachable water-stop joint 2 and the tie rod assembly can be disassembled and reused, thereby reducing material waste.

[0037] In one embodiment, the horn-shaped detachable waterstop joint 2 includes: an integrally formed horn portion 201 and a connecting portion 202. The connecting portion 202 is located at the small-diameter end of the horn portion 201 and is cylindrical. An inner support member 203 is fixedly provided on the inner side of the horn portion 201. The number of inner support members 203 is set to a plurality, and the plurality of inner support members 203 are distributed in a ring array. The inner support members 203 can increase the structural strength of the horn portion 201, and the setting of the inner support members 203 facilitates the operation position when the inner support members 203 are subsequently disassembled.

[0038] In one embodiment, an external thread is provided on the outer side of the connecting part 202, and an internal thread is provided on the inner side of the end of the through-wall sleeve 1. The connecting part 202 is threadedly installed with the end of the through-wall sleeve 1.

[0039] In one embodiment, the connecting part 202 is fixedly connected to the end of the through sleeve 1 using hot melt adhesive.

[0040] In one embodiment, the connecting part 202 is tightly and locked to the end of the through-wall sleeve 1, or the connecting part 202 and the end of the through-wall sleeve 1 are fixed together by an interference fit.

[0041] In one embodiment, a grip pad 3 and a pull handle 4 are fitted on the pull screw 5 and located on the outside of the template. A nut 6 is threaded on the pull screw 5 and located on the outside of the pull handle 4. The nuts 6 are generally designed in two sets to ensure the stability of the connection.

[0042] When in use, the pull handle 4 rests against the outside of the handle pad 3, and the two claws of the handle pad 3 rest against the wooden template. The user can tighten the nut 6 to push the pull handle 4 inward, thereby fixing the two templates.
