Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to an assembled building fastening mechanism. Background Art

[0002] The so-called fastening device generally refers to the intermediate connecting parts connecting two components. In construction projects, it is mostly used to fix and connect steel pipe scaffolding. The fastening device is divided into right-angle fasteners, rotating fasteners, butt fasteners, etc. In use, the fastening device must also provide sufficient elasticity. To this end, the fastening device must have sufficient strength and durability, and effectively maintain a reliable connection between buildings. In addition, the fastener system is also required to have fewer parts, simple installation, and easy disassembly.

[0003] However, there are many types of existing fastening devices, and different fastening devices are selected according to different needs, which causes a lot of inconvenience to technical workers in the early stage of installation, and the installation method is too complicated. Therefore, how to design a building fastening device with simple structure and convenient and quick installation has become a problem we need to solve. Summary of the invention

[0004] The purpose of the present invention is to solve the above problems and to design an assembled building fastening mechanism.

[0006] The locking assembly can cover the port of the steel pipe and lock the steel pipe on the clamp by driving the clamp to clamp.

[0007] The locking assembly includes a boss and several extrusion blocks. The boss is provided with a through hole 1, and the through hole 1 connects the upper surface of the boss with the lower surface of the base. The extrusion block is fixedly installed on the lower surface of the cover plate. The cover plate is provided with a through hole 2, and the position and size of the through hole 2 match the position and size of the through hole 1. The shape and position of the extrusion block match the shape and position of the gap between two adjacent hoops. The extrusion block can be embedded in the matching gap. The hoop clamps the steel pipe under the drive of the extrusion blocks on both sides. The boss can be inserted into the area surrounded by several extrusion blocks, and the side surface of the boss is tightly fitted with the inner surface of the extrusion block.

[0008] The boss is a cylindrical structure, the height of the hoop is smaller than the height of the boss, and the height of the boss matches the thickness of the extrusion block. When the extrusion block is embedded in the gap between two adjacent hoops, the lower surface of the cover plate can press the upper surface of the boss. A plurality of recesses are provided on the side of the boss, and the positions of the plurality of recesses correspond one to one to the positions of the plurality of hoops. A socket is provided at the recess, and the port of the steel pipe on the hoop can be inserted into the corresponding socket and form an interference fit therewith.

[0009] The boss is fixedly installed at the center of the upper surface of the base, the through hole 2 is located at the center of the cover plate, the center lines of the through hole 1, the through hole 2 and the boss are located on the same straight line, the through hole 1 and the through hole 2 are connected in series by bolts, the upper end of the bolt extends to the top of the cover plate, and the lower end of the bolt extends to the bottom of the base, nuts are installed on the upper and lower ends of the bolts, the nuts clamp the cover plate and the base together and prompt the clamping block to be inserted into the gap to form a fixed connection structure.

[0010] The base and the cover plate are both disc-shaped structures, the diameter of the base is the same as the diameter of the cover plate, the hoops are distributed around the boss at equal distances on the same circumference, and the number of the hoops and the extrusion blocks are both four.

[0011] The extrusion block is a block structure with a fan-shaped cross-section. The size of the lower surface of the extrusion block is smaller than the size of its upper surface, thereby forming an inverted trapezoidal structure that is wide at the top and narrow at the bottom. The upper surface of the extrusion block is fixedly connected to the lower surface of the cover plate. The inner surface and the outer surface of the extrusion block are both vertical surfaces. When the boss is inserted into the area surrounded by the extrusion block, the outer surface of the extrusion block is aligned with the edge of the cover plate, and the inner surface of the extrusion block is tightly fitted with the side surface of the boss. The left and right sides of the extrusion block are both inclined surfaces. When the extrusion block is inserted into the gap, its left and right sides can cause extrusion to the clamps on both sides.

[0012] The through hole one and the through hole two are both circular holes with the same diameter, and the diameter of the bolt matches the diameter of the through hole one and the through hole two.

[0013] Beneficial Effects

[0014] An assembled building fastening mechanism manufactured using the technical solution of the present invention has the following advantages:

[0015] 1. This device uses a cover plate, a base and a locking assembly to form a fastening connection mechanism for building steel pipes. It can fasten and connect multiple steel pipes at one time without the need to fix the steel pipes multiple times, which effectively improves work efficiency and reduces the work intensity of staff;

[0016] 2. In the process of fastening the steel pipe, the device only needs to connect the cover plate and the base together. The fastening process can be quickly completed by one bolt and two nuts. The installation process is very convenient and the practical performance is stronger. BRIEF DESCRIPTION OF THE DRAWINGS
