TECHNICAL FIELD

[0001] The utility model relates to building engineering pipeline protection technical field especially relates to a building engineering pipeline anti-cracking protection device. BACKGROUND

[0002] A pipeline is a device for conveying gas, liquid or fluid containing solid particles, which is connected by pipes, pipe connecting parts and valves. Generally, the fluid flows from high pressure to low pressure of the pipeline after being pressurized by a blower, a compressor, a pump and a boiler, etc. It can also be conveyed by using the pressure or gravity of the fluid itself.

[0003] After the building engineering pipeline is welded, in order to avoid the disadvantage of low pressure resistance of the pipeline caused by improper welding technology, reinforcement is needed at the welding position to avoid cracks in the weld due to pressure, so the pipeline needs to be protected against cracking. At present, the commonly used anti-cracking protection structure is a clamping sleeve, which is sleeved on the outside of the pipeline weld and then fastened by bolts. However, for large diameter pipelines, the upper and lower clamping sleeves need to be supported and limited during installation of the bolts to make the bolt holes opposite, so that the bolts can be conveniently tightened, which requires multiple workers to cooperate and adjust, increasing the personnel investment and reducing the installation efficiency. Therefore, the present application provides a building engineering pipeline anti-cracking protection device. SUMMARY

[0005] The embodiment of the utility model provides a building engineering pipeline anti-cracking protection device, which comprises:

[0006] The upper and lower arc-shaped plates are the same size, two upper connecting plates are fixed at the two ends of the upper arc-shaped plate, and two lower connecting plates are fixed at the two ends of the lower arc-shaped plate;

[0007] A connecting assembly, the connecting assembly comprises an L-shaped plate fixed on the lower connecting plate, the L-shaped plate can slide against the upper connecting plate, two limiting blocks are fixed on the L-shaped plate, the limiting blocks can connect the upper and lower arc-shaped plates together when the limiting blocks slide against the upper end of the upper connecting plate, and the upper and lower connecting plates are connected by a connecting piece.

[0008] Further, the upper and lower arc-shaped plates are arranged in a semicircular shape, and rubber pads are fixed on the inner walls of the upper and lower arc-shaped plates.

[0009] Further, the upper connecting plate is integrally formed with the upper arc-shaped plate, and the lower connecting plate is integrally formed with the lower arc-shaped plate.

[0010] Furthermore, the limiting blocks are located at both ends of the L-shaped plate, and the limiting blocks are integrally formed with the L-shaped plate.

[0011] Furthermore, a drainage hole is provided through the limiting block.

[0012] Furthermore, the connector includes a bolt and a nut. Both the upper and lower connecting plates are provided with through holes. After the bolt passes through the through hole, it can abut against the L-shaped plate. The nut engages with the bolt to fasten the upper and lower connecting plates together.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model allows the upper and lower arc-shaped plates to be fastened onto the pipe and pushed relative to each other, so that the limiting block can be fastened onto the upper connecting plate. This allows the upper and lower arc-shaped plates to be installed on the pipe without the need for multiple workers to coordinate adjustment and support, thus improving installation efficiency and reducing the input of human resources. Furthermore, the fastening work can be achieved simply by tightening the nuts, without the need to use a wrench to position the bolts, reducing the use of tools. Attached Figure Description

[0019] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0020] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a crack prevention protection device for pipelines in building engineering, comprising:

[0021] The upper arc-shaped plate 1 and the lower arc-shaped plate 2 are of the same size, and are arranged in a semicircular shape for clamping and protecting the pipeline, and the inner walls of the upper arc-shaped plate 1 and the lower arc-shaped plate 2 are fixed with rubber pads 3.

[0022] The connecting assembly comprises an L-shaped plate 6 fixed on the lower connecting plate 5, the L-shaped plate 6 can slide against the upper connecting plate 4, and the side wall of the L-shaped plate 6 can slide against the side wall of the upper connecting plate 4.

[0023] Two limiting blocks 7 are fixed on the L-shaped plate 6, and when the limiting blocks 7 slide against the upper end of the upper connecting plate 4, the upper arc-shaped plate 1 and the lower arc-shaped plate 2 can be connected together, and the specific explanation is as follows: the upper arc-shaped plate 1 is buckled above the pipeline, and then the lower arc-shaped plate 2 is abutted with the bottom of the pipeline, the lower arc-shaped plate 2 drives the L-shaped plate 6 and the limiting blocks 7 to move, so that the limiting blocks 7 can be buckled on the upper connecting plate 4, as shown in Figure 1 , and then the upper arc-shaped plate 1 and the lower arc-shaped plate 2 are adjusted, so that the through holes on the upper connecting plate 4 and the lower connecting plate 5 are opposite, so that the preliminary installation of the upper arc-shaped plate 1 and the lower arc-shaped plate 2 is realized, which is simple and fast, and only relative pushing is needed to realize the installation.

[0024] As shown in Figure 1 , a simple groove is formed between the limiting block 7 and the upper connecting plate 4, in order to avoid the accumulation of rainwater in the groove, a drainage hole 8 is provided on the limiting block 7, through which the rainwater can be discharged, avoiding the corrosion of the bolt 9 caused by the accumulation of rainwater.

[0025] The upper connecting plate 4 and the lower connecting plate 5 are connected by a connecting piece, the connecting piece comprises a bolt 9 and a nut 10, and the upper connecting plate 4 and the lower connecting plate 5 are both provided with through holes, and the bolt 9 can abut against the L-shaped plate 6 after passing through the through hole, as shown in Figure 1 , at this time, the six-sided block on the upper end of the bolt 9 abuts against the L-shaped plate 6, so that the bolt 9 can be limited, therefore, when the bolt 9 and the nut 10 are tightened, the worker only needs to rotate the nut 10 by using a wrench, without the need to use a wrench to position the bolt 9, thereby reducing the use of tools, and the installation of the bolt 9 and the nut 10 is more convenient.

[0026] The nut 10 engages with the bolt 9 to tighten the upper connecting plate 4 and the lower connecting plate 5 together, so that the upper arc-shaped plate 1 and the lower arc-shaped plate 2 do not need to be adjusted and supported by multiple workers during installation, thereby improving the installation efficiency and reducing the investment in human resources.
