Technical Field
[0001] This utility model relates to the field of building technology, specifically to a prestressed concrete precast pile welding windbreak device. Background Technology
[0002] Prestressed concrete precast piles are suitable for foundation treatment of silt, silty soil, cohesive soil, silt, sand, and artificial fill. They are the most widely used type of building foundation, with a large usage volume, high degree of mechanization, fast construction speed, and increasingly higher quality requirements for precast pile foundations.
[0003] Currently, low-strain testing of precast piles has revealed defects at the joints between some precast piles, affecting the quality of the pile foundation. While CO2 gas shielded welding is commonly used for precast pile joints, the outdoor location of these piles makes them susceptible to wind damage, significantly impacting welding quality and resulting in poor weld quality at the pile foundation joints. Therefore, we propose a windbreak device for welding prestressed concrete precast piles. Utility Model Content

This device has the advantage of reducing wind interference in the welding area during the welding process by surrounding the precast pipe pile with a windbreak screen, thus solving the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a prestressed concrete precast pile welding windbreak device, including a first column, a universal wheel at the lower end of the first column driving the device to move, a clamping plate fixedly connected to the inner side of the first column, a windbreak screen with welding protection performance installed on the inner side of the clamping plate, a second column and a front limiting plate respectively installed at the rear end and front end of the windbreak screen, and an installation plate fixedly connected to the lower part of the second column.
[0006] Preferably, the first column and the second column drive the windbreak screen to form a circle, and a precast pipe pile is installed on the inner side of the circular windbreak screen.
[0007] Preferably, the windbreak screen includes a first fiberglass fireproof cloth, a windproof tarpaulin, and a second fiberglass fireproof cloth, with the windproof tarpaulin sandwiched between the first and second fiberglass fireproof cloths.
[0008] Preferably, the clamp is equipped with fastening bolts that define both ends of the windshield screen, and the fastening bolts pass through the interior of the clamp and the windshield screen in sequence.
[0009] Preferably, hinges are installed at the rear ends of the two sets of second columns, and three sets of second columns are installed between the two sets of first columns.

[0011] Preferably, the front limiting plate is installed at the front end of the second column by fastening threads, and the windshield screen is clamped between the second column and the front limiting plate.
[0012] Compared with existing prestressed concrete precast pile welded windbreak devices, this utility model has the following advantages:
[0013] 1. The prestressed concrete precast pile welding windbreak device, through the first column and the second column, drives the windbreak screen to form a circle. At the same time, the windbreak screen is sleeved on the outside of the precast pipe pile. That is, the windbreak screen is completely enclosed when the precast pipe pile is welded, and the pipe pile joint is basically unaffected by the wind during welding, which greatly improves the quality of the pile foundation joint.
[0014] 2. The prestressed concrete precast pile welded windbreak device is installed on the inner side of the clamping plate through both sides of the windbreak screen to ensure the stability of the windbreak screen when it is installed on the inner side of the clamping plate.
