Description

Technical Field

[0001] This utility model relates to the technical field of fire sprinkler branch pipes, specifically a positioning and clamping mechanism for fire sprinkler branch pipes used in prefabricated buildings. Background Technology

[0002] Fire sprinkler branch pipes, also known as terminal drainage pipes of fire sprinkler fire prevention systems, are an important component of fire sprinkler fire prevention systems. They are usually used in conjunction with main pipes and sprinkler heads and are typically used in buildings.

[0003] Currently, during the installation of fire sprinkler branch pipes in buildings, a positioning and clamping structure is used to restrict and fix the position of the fire sprinkler branch pipes. This involves placing the existing fire sprinkler branch pipe on a U-shaped frame, then attaching a U-shaped clamp to the outside of the fire sprinkler branch pipe, and finally fixing it with bolts. However, this structure has some problems in practical application. When the bolt engages at one end of the U-shaped clamp, the clamp tends to tilt, making it difficult for personnel to tighten the bolts at the other end. Therefore, we propose a fire sprinkler branch pipe positioning and clamping mechanism for prefabricated buildings to solve these problems. Utility Model Content

[0006] As a further preferred embodiment of this technical solution, the outer side of the outer ring plate abuts against the inner wall of the perforation, and the outer side of the pressure plate abuts against the inner wall of the perforation.

[0007] As a further preferred embodiment of this technical solution, the outer edge of the bottom end of the outer ring plate is set in an arc shape, and the outer ring plate and the pressure plate have the same diameter.

[0008] As a further preferred embodiment of this technical solution, the top and bottom ends of the square plate abut against the outer sides of the U-shaped bracket and the fire sprinkler branch pipe, respectively, and the bolts and hexagonal nuts are connected by fine-thread engagement.

[0009] As a further preferred embodiment of this technical solution, a side groove is provided on the outer side of the square plate, and a magnetic sheet is fixedly installed inside the side groove.

[0010] As a further preferred embodiment of this technical solution, the snap-fit ​​component includes a T-shaped block, which is fixedly mounted on the top of the U-shaped bracket. The T-shaped block is inserted into the interior of the T-shaped groove, which is located on the outer side of the fixing plate. The outer side of the T-shaped block abuts against the inner wall of the T-shaped groove.

[0011] As a further preferred embodiment of this technical solution, the outer edges of both the T-block and the T-slot are inclined.

[0012] This utility model provides a positioning and clamping mechanism for fire sprinkler branch pipes in prefabricated buildings, which has the following advantages:

[0013] This utility model involves placing a fire sprinkler branch pipe fitting on a U-shaped bracket, then fitting a U-shaped clamp onto the outside of the fire sprinkler branch pipe fitting, and fitting two sets of square plates onto the outside of the U-shaped clamp. The ends of the U-shaped clamp, the outer ring plate, and the pressure plate are then inserted into the through holes, during which the bolt moves downward within the circular holes. A hexagonal nut engages with the outside of the bolt, and the hexagonal nut is tightly pressed against the outside of the U-shaped bracket. The pressure plate also presses firmly downward against the outer ring plate. Thus, the U-shaped clamp applies pressure to the outside of the fire sprinkler branch pipe fitting for positioning and clamping. This structure is simple and easy to operate, and can fix the position of the fire sprinkler branch pipe fitting in one operation.

[0014] This utility model, by providing a snap-fit ​​component, enables the fixing plate and the U-shaped bracket to be detached, that is, the T-shaped block can be taken out from the inside of the T-shaped groove, thereby facilitating the carrying and operation of the structure by personnel. The T-shaped block can be directly inserted into the inside of the T-shaped groove, which can quickly connect the fixing plate and the U-shaped bracket. Attached Figure Description

Hexagonal nut 12 is tightly pressed against the outside of U-shaped bracket 2, and pressure plate 8 can tightly press the outer ring plate 7 downward. Thus, U-shaped clamp 5 can be pressurized on the outside of fire sprinkler branch pipe fitting 4 to perform positioning and clamping work. This structure is simple and easy to operate, and can fix the position of fire sprinkler branch pipe fitting 4 in one go. The outer side of the outer ring plate 7 abuts against the inner wall of the through hole 6, and the outer side of the pressure plate 8 abuts against the inner wall of the through hole 6, so that the outer ring plate 7 can restrict the position of U-shaped clamp 5.

The two ends of the U-shaped clamp 5, the outer ring plate 7, and the pressure plate 8 are then inserted into the through hole 6. During this process, the bolt 10 moves downward within the round hole 11. Then, the hexagonal nut 12 is engaged with the outside of the bolt 10, so that the hexagonal nut 12 is tightly attached to the outside of the U-shaped bracket 2, and the pressure plate 8 can press the outer ring plate 7 downward tightly. Thus, the U-shaped clamp 5 can apply pressure to the outside of the fire sprinkler branch pipe fitting 4 to fix it.
