Description
Technical Field
The utility model relates to a construction field specifically is a depression bar for reducing peg pierces through and welds clearance.
Background
At present, in traditional stud welding construction, when building carrier plate and girder steel surface clearance are great, mainly adopt the method that the tup was strikeed. When the hammer head is used for knocking, each stud welding point needs to be knocked, the position and the section width of each stud steel beam needing to be welded are very clear, the operation method mainly has the following two requirements, firstly, the position and the section size of the steel beam need to be controlled very clearly by welding personnel, otherwise, the floor bearing plate bottom plate at the suspended position is easy to be knocked through by mistake, the cavity is filled in the later period, and even the slurry leakage condition during concrete beating can occur. Secondly, every stud welding point all needs to strike, and work load is very big, and to the great place in some clearance, must not make floor support plate bottom plate and girder steel surface closely laminate after striking, can strike the bottom plate even, forms the hole.
In order to solve the problem that the quality of the welding stud is poor due to the large surface gap between the floor support plate bottom plate and the steel beam, the adopted measures mainly tend to reduce the gap by using a pressure rod device. For example, the patent with the application number of cn201711157990.x, the application number of "a device convenient for the profiled steel sheet to weld the studs", the application number of CN201620005767.8, the application number of "a floor support plate back pressure auxiliary device", the application number of CN201720698073.1, the application number of "a pressure bar capable of ensuring the welding quality of the profiled steel sheet and the studs", all of the three patents disclose a pressure bar back pressure device, which uses the lever principle, selects the vertical rod as the fulcrum, and uses the welded studs as the stress points to perform floor support plate back pressure, thereby solving the problem of large gap between the floor support plate bottom plate and the steel beam and ensuring the welding quality of the studs. However, the method has the disadvantages that when the previous stud is used as an acting point to press against the floor bearing plate, the position of the stud to be welded may coincide with the position of the pressure rod up and down, the distance between the pressure rod and the floor bearing plate does not satisfy the vertical welding of the stud gun or the welding personnel cannot be guaranteed to keep the correct gun-holding welding posture, the stud and the steel beam surface are not vertical during welding to cause partial welding, and the welding quality cannot be guaranteed.
