Description
Technical Field
The utility model relates to a foundation ditch support field specifically is a exempt from to weld, exempt from to demolish bracket for steel sheet pile.
Background
In the process of supporting the foundation pit, after the steel sheet piles are inserted and driven to finish excavating a first layer of soil body, corbel leveling and installation are needed. The conventional method for installing the bracket is welding, namely full welding between the bracket and the steel sheet pile, and although the method is firm, the method has the following defects:
1. the welding process takes a long time;
2. after the supporting structure is used, the bracket is required to be dismantled (if the bracket is not dismantled, the bracket cannot be guaranteed to be on the same horizontal plane in the next use), which is labor-consuming and time-consuming;
3. the material is damaged by multiple welding and dismantling, and the repeated use of the material is influenced.
Disclosure of Invention
To the above situation, for overcoming prior art's defect, the utility model provides a welding-free, exempt from to demolish bracket for steel sheet pile, the effectual bracket welding of having solved, demolish that the labour-and-time-consuming and cause the material to destroy, influence used repeatedly's problem.
The technical scheme of its solution is, a exempt from to weld, exempt from to demolish bracket for steel sheet pile, including vertical steel sheet pile and bracket subassembly, seted up vertical spout on the steel sheet pile, the bracket subassembly includes a backplate parallel with the steel sheet pile, the welding has rather than vertically bracket on the backplate, wears to be equipped with the bolt on the backplate, in arranging the spout in of bolt, can fix the backplate on the steel sheet pile when the bolt is screwed up, the bolt loosens and to make the backplate slide from top to bottom along the spout.
The utility model discloses fine solution the bracket welding, the problem of demolising, and compare with conventional method, convenient operation, laborsaving saving time, reduce cost improves work efficiency.

Detailed Description
The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings.
By figure 1 to figure 6, the utility model discloses a vertical steel sheet pile 1 and bracket 4 subassembly have seted up vertical spout 2 on the steel sheet pile 1, and bracket 4 subassembly includes a backplate 3 parallel with steel sheet pile 1, and the welding has rather than vertically bracket 4 on the backplate 3, wears to be equipped with bolt 5 on the backplate 3, and in arranging spout 2 in of bolt 5, can fix backplate 3 on steel sheet pile 1 when bolt 5 screws up, bolt 5 loosens and to make backplate 3 slide from top to bottom along spout 2.
Two sliding grooves 2 are symmetrically formed in the steel sheet pile 1 in the left-right direction, four bolts 5 are arranged on the back plate 3, two bolts 5 penetrate through the sliding grooves 2 in each side, the back plate 3 can be stably fixed on the steel sheet pile 1 through the four bolts 5, and the back plate 3 is prevented from sliding and twisting.
The head of the bolt 5 is welded with a stop block 6, so that the nut is prevented from falling off in the material using and transferring processes.
The utility model discloses when using, the survey crew uses every 20m survey 1 point of GPS or theodolite, emits the supporting construction sideline, then spills the lime line subaerial, then adopts the vibratory hammer to squeeze into the soil body according to the lime line with steel sheet pile 1 in proper order, and a plurality of steel sheet piles 1 are protected and are bored the body edge, excavate the first layer soil body afterwards, and the first layer soil body excavates to enclosing purlin position 50-100cm below, makes things convenient for workman's adjustment fixed bracket 4 and installation to enclose the purlin.
Note that the steel sheet pile 1 with the bracket 4 is to descend the bracket 4 assembly to the bottom of the chute 2 before driving, and then to insert and drive after tightening the bolt 5. In the method, the height of the bracket 4 assembly is conveniently adjusted, because one end of the bolt 5 is arranged in the soil layer, after the first layer of soil is excavated, the bolt 5 cannot be subjected to the resistance of the soil when the bracket 4 is adjusted upwards, and the adjustment is more convenient; on the contrary, if the bracket 4 component is adjusted downwards, the end of the bolt 5 is affected by the soil body below, and the adjustment is laborious.
After the excavation of the first layer of soil body is finished, marking the positions of the top surfaces of the designed brackets 4 on the steel sheet piles 1 on the two sides at intervals of 20m by adopting a level gauge, then manually pulling a wire, marking the designed elevation of the top surface of each bracket 4 on each steel sheet pile 1 with the bracket 4, loosening the bolts 5, moving the bracket 4 to the designed height, then screwing the bolts 5, and adjusting all the brackets 4 one by one according to the method; and after the bracket 4 is adjusted and fixed, installing an enclosing purlin and a cross brace on the bracket 4, then excavating a second layer of soil body, and carrying out engineering construction in a foundation pit.
After the supporting structure is used, the surrounding purlin and the cross brace are disassembled, the bolts 5 are loosened, and the steel sheet pile 1 is directly pulled out.
The utility model has the advantages that:
1. the sliding chute 2 on the steel sheet pile 1 can realize the free leveling of the bracket 4;
2. a back plate 3 is additionally arranged on the bracket 4, so that the contact area between the bracket 4 and the steel sheet pile 1 is increased, and the bracket 4 and the steel sheet pile 1 can be effectively fixed;
3. the purposes of welding-free and dismantling-free can be realized.
The utility model discloses fine solution bracket 4 welding, demolish that it is time-consuming to take a lot of work, destroy difficult problems such as material, and compare with conventional method, saved the process of component welding and excision for the construction progress has practiced thrift construction cost, has improved the rate of utilization of material.
