Description

Technical Field

[0001] This utility model relates to the field of steel grating formwork assembly, specifically to a modular bolt assembly structure for steel grating formwork. Background Technology

[0002] In the construction industry, the assembly and fixing of steel grating formwork is a crucial step in the construction process. Traditional assembly methods mainly rely on tools such as C-clamps. While these tools meet the needs of steel grating formwork splicing to a certain extent, there are still many areas for improvement in practical use.

[0003] In the existing C-type mounting clip, the upper convex plate is placed above the splicing template and the lower convex plate is placed below the template. Then, the entire mounting clip is moved so that the connection between the two adjacent templates is located inside the mounting clip. Finally, bolts and nuts are used to lock and fix the clip through the upper and lower convex plates.

[0004] However, the existing C-type mounting clips have a relatively simple structure and are mostly one-piece structures. The spacing between the upper and lower convex plates is fixed and cannot be adjusted according to the different heights of the steel grating template. This results in the C-type mounting clips not being able to accurately match steel grating templates of different heights, thus affecting the splicing and fixing effect.

[0005] Therefore, it is necessary to invent a modular bolt assembly structure for steel grating templates. Utility Model Content

[0006] The purpose of this invention is to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular bolt assembly structure for steel grating templates, including an installation clamp assembly and a fixing screw. The fixing screw movably passes through one side of the installation clamp assembly. The installation clamp assembly includes a positioning plate and an upper convex plate fixedly connected to the upper side of the positioning plate. A lower convex plate is fixedly connected to the lower side of the positioning plate. The fixing screw movably passes through the middle of the upper and lower convex plates. A back plate is provided on the side of the positioning plate away from the fixing screw. A protective cover is movably connected to the bottom of the lower convex plate.

[0008] Based on the above features: the spacing between the upper and lower convex plates can be adjusted according to the height of the steel grating template, so that the connection between two adjacent steel grating templates is located between the positioning plate, upper convex plate, and lower convex plate of the C-shaped structure. Then, the fixing screw passes through the upper and lower convex plates, so that the fixing screw can limit the upper and lower convex plates on the side away from the positioning plate.

[0009] Preferably, the positioning plate, the upper convex plate, and the lower convex plate are all integral structures, and the positioning plate and the lower convex plate are in an L-shape.

[0010] Based on the above features, it is convenient to fix the connection between two adjacent steel grating templates using the positioning plate, upper convex plate, and lower convex plate.

[0011] Preferably, a limiting groove is formed in the middle of the positioning plate, and guide grooves are symmetrically formed on the inner walls of both sides of the limiting groove.

[0012] Based on the above features: it facilitates the opposite displacement of the upper and lower convex plates, and the spacing between the upper and lower convex plates can be adjusted according to the height of the steel grating template.

[0013] Preferably, both the lower convex plate and the upper convex plate have through holes in the middle, and a magnetic suction piece is fixedly connected to the bottom of the lower convex plate.

[0014] Based on the above features: the fixing screw can be moved through the through hole, which makes it convenient for the fixing screw to limit one side of the principle positioning plate.

[0015] Preferably, the fixing screw is externally threaded with a locking nut.

[0016] Based on the above features: the locking nut is threaded below the fixing screw, and after the locking nut is tightened and installed, it will be located below the lower convex plate to prevent the fixing screw from coming off by itself.

[0017] Preferably, the back plate has symmetrically welded limit blocks at both ends on the side closest to the positioning plate, and guide sliders are symmetrically connected to both sides of the end of the limit blocks away from the back plate.

[0018] Based on the above features: the back plate is slidably connected to the limiting groove through the limiting block to prevent the upper and lower convex plates from separating from the positioning plate when they move in opposite directions, while the guide slider is slidably connected to the guide groove to allow the upper and lower convex plates to move vertically.

[0019] Preferably, a metal sheet is fixedly connected to the upper end of the protective cover.

[0020] Based on the above features: the protective cover can be easily fixed by adsorption between the metal sheet and the magnetic sheet. At this time, the protective cover is located at the bottom of the lower convex plate to protect the connection between the locking nut and the fixing screw, and to avoid rainwater adhesion as much as possible.

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

[0022] 1. By dividing the positioning plate into two parts, the upper and lower convex plates can be adjusted according to the height of the steel grating template. The back plate is slidably connected to the positioning plate through the limiting block and the limiting groove in the middle, while the guide slider is slidably connected to the guide groove, so that the upper and lower convex plates can be vertically displaced and will not separate from the positioning plate during the displacement. After the positioning plate, upper convex plate and lower convex plate are fixed at the connection of two adjacent steel grating templates, the fixing screw can be moved through the through hole. Finally, the locking nut can be used to lock and fix the fixing screw below. This can adapt to steel grating templates of different heights and improve the flexibility and versatility of assembly.

[0023] 2. The protective cover can protect the connection between the fixing screw and the locking nut. The protective cover can be fixed by magnetic attraction between the metal sheet and the bottom of the lower convex plate. At this time, the protective cover is located at the bottom of the lower convex plate, and the connection between the locking nut and the fixing screw will be located inside the protective cover, preventing them from being corroded by external rainwater and extending their service life.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0031] See attached document Figure 5 The existing product features a C-type mounting clip connected to a steel grating template. The mounting clip assembly is a C-type clip. When two sets of steel grating templates need to be assembled together, the C-type mounting clip is inserted into the inner gap of one of the steel grating templates. Then, the upper convex plate 2 of the C-type mounting clip is placed above the steel grating template at the splicing point, while the lower convex plate 3 below the C-type mounting clip is located below the steel grating template. The C-type mounting clip is then pushed to displace it, so that the splicing point of the two adjacent steel grating templates is located inside the C-type mounting clip. During this process, the upper convex plate 2 and the lower convex plate 3 extend to the gap of the other steel grating template. Holes are provided in the middle of both the upper convex plate 2 and the lower convex plate 3. When fixing is required, a fixing screw 4 can be used to pass through, and then a nut can be used to lock the bottom of the fixing screw 4, thereby fixing the two steel grating templates together.

[0032] See attached document Figure 1-4 The modular bolt assembly structure of the steel grating template provided by this utility model includes a positioning plate 1 and an upper convex plate 2 fixedly connected to one side of the upper end of the positioning plate 1. A lower convex plate 3 is fixedly connected to one side of the lower end of the positioning plate 1. The positioning plate 1, the upper convex plate 2, and the lower convex plate 3 are all integral structures. The positioning plate 1 and the lower convex plate 3 are in an L-shaped structure. A through hole 31 is provided in the middle of the lower convex plate 3 and the upper convex plate 2. A fixing screw 4 is movably passed through the through hole 31. A locking nut 41 is threadedly connected to the outside of the fixing screw 4. When the fixing screw 4 passes through the through hole 31, it can be threadedly connected to the fixing screw 4 from below using the locking nut 41.

[0033] The positioning plate 1 is divided into two parts. The upper part of the positioning plate 1 is fixedly connected to the upper convex plate 2, and the lower part of the positioning plate 1 is fixedly connected to the lower convex plate 3. A limiting groove 11 is opened in the middle of the positioning plate 1. Guide grooves 12 are symmetrically opened on the inner walls of the limiting groove 11 to facilitate the positioning plate 1 to move in opposite directions, so that the upper convex plate 2 and the lower convex plate 3 move away from each other or move closer to each other, thereby expanding or reducing the distance between the upper convex plate 2 and the lower convex plate 3.

[0034] A back plate 5 is provided on the side of the positioning plate 1 away from the fixing screw 4. Limiting blocks 51 are symmetrically welded to both ends of the side of the back plate 5 closest to the positioning plate 1. The back plate 5 is attached to one side of the positioning plate 1, and the back plate 5 is inserted into the inside of the limiting groove 11 by means of the limiting blocks 51, so that the positioning plate 1 divided into two can slide and move in opposite directions. Guide sliders 52 are symmetrically connected to both sides of the end of the limiting block 51 away from the back plate 5. The guide sliders 52 are slidably connected to the guide groove 12 to prevent the limiting block 51 from separating from the limiting groove 11.

[0035] When the installation clamp assembly needs to be connected and fixed, the distance between the upper convex plate 2 and the lower convex plate 3 can be adjusted in advance according to the height of the steel grating template. When it is necessary to increase the distance between the upper convex plate 2 and the lower convex plate 3, the two positioning plates 1 can be pulled away from each other so that the distance between the upper convex plate 2 and the lower convex plate 3 is greater than or equal to the height of the steel grating template. Then, the installation clamp assembly can be used to fix the connection of the two adjacent steel grating templates. At this time, the upper convex plate 2 will be located above the steel grating template, and the lower convex plate 3 will be located below the steel grating template. Then, the fixing screw 4 is used to pass through the through hole 31, and the locking nut 41 is used to connect to the fixing screw 4 from below, so that the two positioning plates 1 cannot be moved. At the same time, the side of the upper convex plate 2 and the lower convex plate 3 away from the positioning plate 1 can be limited, so that the entire installation clamp assembly will not separate from the steel grating template. When disassembly is required, simply unscrew the locking nut 41 to separate it from the fixing screw 4, and then pull out the fixing screw 4.

[0036] See attached document Figure 1-4 The modular bolt assembly structure of the steel grating template provided by this utility model has a magnetic suction plate 32 fixedly connected to the bottom of the lower convex plate 3. The magnetic suction plate 32 can be fixed by welding or screws. A protective cover 6 (which can be transparent, but is not specifically limited) is movably connected to the bottom of the lower convex plate 3. A metal plate 61 (fixed by welding or screws) is fixedly connected to the upper end of the protective cover 6. The protective cover 6 is a U-shaped structure with one end open and the other end sealed. The magnetic suction plate 32 and the metal plate 61 are U-shaped structures with a hollow space in between. When the locking nut 41 and the fixing screw 4 are connected, the locking nut 41 will be located between the bottom of the lower convex plate 3 and the magnetic suction plate 32. At this time, the protective cover 6 can be connected to the bottom of the lower convex plate 3. The protective cover 6 can be fixed by the magnetic suction plate 32 using the metal plate 61. The connection between the locking nut 41 and the fixing screw 4 will be located inside the protective cover 6 to prevent it from being corroded by external rainwater and extend its service life.
