Description
Technical Field
The utility model relates to a bearing structure of bridge construction field large steel construction, concretely relates to install bracket structure that shears at steel-pipe pile top.
Background
Often adopt the steel-pipe pile as the bearing structure of support or platform in road bridge engineering, set up the corbel at the steel pipe top and regard as superstructure's strong point, all loads of superstructure all transmit the steel-pipe pile through the corbel on. The conventional bracket adopts two triangular or trapezoidal steel plates (shear plates) to weld the outer side of the steel pipe, the panel is welded at the top of the shear plate to form the steel bracket, the vertical welding and overhead welding are involved in the bracket welding process, the welding quality of the overhead welding is difficult to guarantee under the influence of the field construction environment, and the steel pipe opening is easily torn by the bracket when bearing large load, so that safety accidents are caused.
Disclosure of Invention
The utility model aims at the defect that current steel-pipe pile top bracket structure exists, provide one kind and install the bracket structure that shears at steel-pipe pile top, with difficult welded position by the scene to the processing field in prefabricated, then transport to the field installation to reduce the construction degree of difficulty, improve construction quality, optimize the bracket structure simultaneously, increase the steel-pipe pile ability of shearing, improve structural security.
The technical scheme of the utility model as follows:
the utility model provides a corbel structure that shears at steel-pipe pile top, includes bracket and steel-pipe pile, its characterized in that: the bracket comprises a horizontally arranged rectangular top plate, the width of the top plate is smaller than the diameter of the steel pipe pile, the length of the top plate is larger than the diameter of the steel pipe pile, and two vertical plates which are perpendicular to the top plate and have a certain distance are welded on the bottom surface of the top plate in parallel along the longitudinal direction of the top plate; two opposite sides of the top of the steel pipe pile are provided with bracket mounting openings with the same width as the top plate, the bottom edge of each bracket mounting opening is provided with two vertical slots extending downwards, the distance between the two slots is equal to the distance between two vertical plates of a bracket, and the depth of each slot is equal to the height of the vertical plate; the two vertical plates of the bracket are respectively inserted into the two slots and welded with the two sides of the slots, and the lengths of the two ends of the top plate extending to the outer side of the steel pipe pile are equal.
The utility model sets the corbels at both sides of the conventional steel pipe pile into an integral structure, converts the shearing resistance of the conventional steel pipe pile into the tensile and bending resistance of the corbel, can effectively improve the shearing resistance and the integral compression resistance of the top of the steel pipe pile, and greatly improves the bearing capacity of the top of the steel pipe pile; because the prefabricated assembly technology is adopted, the on-site overhead welding technology is changed into the flat welding technology in a processing field, the blanking and cutting quality of steel can be ensured, the length of a welding seam of on-site welding is reduced, and the construction quality is improved.

Detailed Description
As shown in fig. 1, 2 and 3, the utility model comprises a bracket and a steel pipe pile, wherein the bracket comprises a horizontally arranged rectangular top plate 1, the width of the top plate 1 is smaller than the diameter of the steel pipe pile 3, the length of the top plate is larger than the diameter of the steel pipe pile, and two vertical plates 2 which are vertical to the top plate and have a certain distance are welded on the bottom surface of the top plate 1 in parallel along the longitudinal direction of the top plate; the structure of the steel pipe pile 3 is shown in fig. 4, two opposite sides of the top of the steel pipe pile are provided with bracket mounting openings 31 with the same width as the top plate, the bottom edge of each bracket mounting opening 31 is provided with two vertical slots 32 extending downwards, the distance between the two slots 32 is equal to the distance between the two vertical plates 2 of the bracket, and the depth of each slot 32 is equal to the height of the vertical plate 2; the two vertical plates 2 of the bracket are respectively inserted into the two slots 32 and welded with the two sides of the slots, and the lengths of the two ends of the top plate 1 extending to the outer side of the steel pipe pile 3 are equal.
The utility model discloses during the concrete implementation, riser 2 is the isosceles trapezoid structure that topside length is greater than base length, and the length on 2 bases of riser is greater than or equal to steel-pipe pile 3's diameter.
The bracket top plate 1 and the two vertical plates 2 of the utility model can be welded in a processing field in advance, the field overhead welding of the common bracket is changed into the flat welding of the processing field, the construction difficulty is greatly reduced, and the welding quality can be ensured; a bracket mounting opening 31 and a slot 32 are formed in the top of the steel pipe pile 3 in advance; after the steel pipe pile is inserted and driven in a construction site, the two vertical plates 2 of the bracket are inserted into the slots 32 of the steel pipe pile and are welded with the slots, and then bracket installation is completed. The installation site only has a vertical welding process, so that the installation quality can be ensured; meanwhile, the load at the top of the steel pipe pile mainly depends on the tensile strength and the bending resistance of the bracket, the shearing force borne by the pipe wall of the steel pipe pile is reduced, and the bearing capacity of the steel pipe pile can be improved.
