Description

Technical Field

[0001] This utility model relates to the field of bolt technology, specifically a reinforced hexagonal head bolt for exterior wall formwork. Background Technology

[0002] Bolts are a type of fastener consisting of a head and a shank (a cylinder with external threads). They are used in conjunction with nuts to fasten two parts with through holes. Bolts are anchoring components that anchor the connected parts to a hardened concrete substrate. During the installation of exterior wall formwork, hexagonal head bolts are often used to clamp and fix them.

[0003] During use, existing hexagonal bolts tend to wear down over time, and because they are often used in the construction industry in humid environments, they are prone to corrosion. This further increases wear and causes the bolt to not fit properly with the wrench, thus affecting the efficiency of bolt disassembly.

[0004] To address the aforementioned issues, we propose a method for using reinforced hexagonal head bolts for exterior wall formwork. Utility Model Content

[0005] To address the problems in the background art, this utility model provides a reinforced hexagonal head bolt for exterior wall formwork.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A reinforcing hexagonal head bolt for exterior wall formwork includes a bolt body and a connecting washer. The bolt body has a connecting disc at its head end, and the connecting washer has an installation groove in the middle of its inner side. When the bolt body is installed in the middle of the connecting washer, the connecting disc is installed in the installation groove, and the connecting disc and the outer surface of the connecting washer are at the same level. The bolt body also has a protective cover at its head end, which is fitted to the outer surface of the connecting washer and locked in place by three sets of screws.

[0008] Preferably, a circular through hole is provided at the center of the head end of the bolt body.

[0009] Preferably, the connecting pad has three sets of connecting holes in the middle of its inner side.

[0010] Preferably, the three sets of connecting holes correspond to the positions of the three sets of screws, and are all distributed in a triangular pattern.

[0011] Preferably, the bottom of the protective cover is provided with a clamping plate, and the clamping surface of the clamping plate is provided with a sealing gasket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this solution, an installation groove is provided in the middle of the connecting pad. During use, the connecting disc of the bolt body is installed in the installation groove, and then the head end of the bolt body is limited and locked to the connecting pad by the protective cover. This effectively improves the stability of the bolt body during use and prevents loosening. In addition, the protective cover seals and protects the head end of the bolt body, which serves to prevent dust and water, thus effectively preventing the head end of the bolt body from being exposed to the outside world and causing damage such as rust, which would make disassembly difficult.

[0014] In this solution, a circular through hole is provided in the middle of the head of the bolt body. If the head of the bolt body becomes worn flat and cannot be properly fitted with a wrench, making disassembly impossible, the worker can insert a pin into the through hole and then disassemble the bolt body by rotating the pin, using the lever principle, thereby enhancing the convenience of disassembly and assembly.

[0016] Figure 2 This is an exploded view of the present invention.

[0018] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0019] Example: Refer to Figures 1-2 As shown, a reinforced hexagonal head bolt for exterior wall formwork in this embodiment includes a bolt body 1 and a connecting plate 2. The head end of the bolt body 1 is provided with a connecting disc 11, and the inner middle of the connecting plate 2 is provided with an installation groove 21. When the bolt body 1 is installed in the middle of the connecting plate 2, the connecting disc 11 is installed in the installation groove 21, and the connecting disc 11 and the outer surface of the connecting plate 2 are at the same horizontal plane.

[0020] The head end of the bolt body 1 is provided with a protective cover 3. The protective cover 3 is fitted to the outer surface of the connecting pad 2 and is installed and locked by three sets of screws 32. The protective cover 3 clamps and fixes the head end of the bolt body 1, thereby limiting and locking the bolt body 1. At the same time, the protective cover 3 can also seal and protect the head end of the bolt body 1, which can prevent dust and water, thus effectively preventing the head end of the bolt body 1 from being exposed to the outside world and causing damage such as rust, which would make disassembly difficult.

[0021] A circular through hole 12 is provided in the middle of the head end of the bolt body 1. A pin can be inserted into the through hole 12, and the bolt body 1 can be twisted by rotating the pin using the lever principle.

[0022] In some examples, the inner center of the connecting pad 2 is provided with three sets of connecting holes 22, which facilitate the screws 32 to pass through the connecting holes 22 and then be threaded to the outer wall template, thereby limiting and fixing the protective cover 3. At the same time, the installation of the three sets of screws 32 will also play a limiting and locking role for the connecting pad 2, further enhancing the stability of the connecting pad 2 during fixed installation.

[0023] In some examples, the three sets of connecting holes 22 correspond to the positions of the three sets of screws 32, and are all distributed in a triangle, which provides stability.

[0024] In some examples, the bottom of the protective cover 3 is provided with a clamping plate 31, and the clamping surface of the clamping plate 31 is provided with a sealing gasket. When the protective cover 3 covers the head end of the bolt body 1, the clamping plate 31 will seal and clamp the gap between the connecting plate 11 and the mounting groove 21, thereby playing a role in dust and water prevention, keeping the head end of the bolt body 1 clean, and thus effectively avoiding the situation where rust damage leads to difficulty in disassembly.

[0025] The working principle of this utility model is as follows:

[0026] During use, the bolt body 1 needs to be connected to the pre-embedded fastening nut in the external wall formwork to clamp and fix the external wall formwork. During installation, the connecting pad 2 needs to be put on first. The connecting pad 2 fits and clamps the external wall formwork, which can increase the clamping area of ​​the external wall formwork. Then, by rotating the bolt body 1, the bolt body 1 will be slowly installed into the connecting pad 2 during the rotation until the connecting disc 11 at the head of the bolt body 1 is completely inserted into the installation groove 21. At this time, the connecting pad 2 is tightened and clamped, and the connecting pad 2 clamps and fixes the external wall formwork.

[0027] When the connecting plate 11 is installed in the mounting groove 21, the outer surface of the connecting plate 11 and the connecting pad 2 are at the same level. The workers can then cover the head of the bolt body 1 with the protective cover 3 to protect it, thereby effectively preventing the head of the bolt body 1 from being exposed to the outside world, which could lead to rust and other damage, and make disassembly difficult.

[0028] Conversely, when it is necessary to disassemble the bolt body 1, simply loosen the three sets of screws 32, remove the protective cover 3, and the well-protected bolt body 1 will be exposed. At this time, the bolt body 1 can be easily disassembled with an electric wrench.

[0029] In addition, by providing a circular through hole 12 in the middle of the head of the bolt body 1, if the head of the bolt body 1 becomes worn flat and difficult to fit with a wrench, making it impossible to disassemble, the worker can insert a pin into the through hole 12 and then disassemble the bolt body 1 by rotating the pin and using the lever principle, thereby enhancing the convenience of disassembly.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
