The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present application and are not to be construed as limiting the present application.

Referring to fig. 1 and 2, the application provides a bearing bracket which can be widely applied to bridge and house construction and can respectively bear shearing force and bending moment of the bracket through different structural members, aiming at the problem that both an anchor bar/profile steel embedded bracket and a climbing cone 33 embedded part bracket can not meet the bearing requirement of the bracket, so that the bearing capacity of the bracket is improved. The bearing bracket comprises a bracket structure 1 and an embedded structure which are connected with each other, the embedded structure is embedded in a fixing component of the bracket to be installed, so that the bearing of the bracket structure 1 is transferred to the fixing component through the embedded structure, and the bracket structure 1 is ensured to have good bearing capacity.

Bracket structure 1 includes mounting panel 11 and bracket board 12, the welding of bracket board 12 vertical ground is in on the mounting panel 11, mounting panel 11 laminates in the setting of fixed component surface, just pre-buried structure with mounting panel 11 is connected, in order to realize bracket structure 1 with pre-buried structure's connection. The embedded structure comprises a climbing cone structure 3 and a pin shaft nesting structure 2, the climbing cone structure 3 is arranged on the upper layer of the bracket structure 1, and the pin shaft nesting structure 2 is arranged on the middle layer of the bracket structure 1.

Specifically, the pin shaft nesting structure 2 comprises a pin shaft 21, an embedded steel pipe 22 and an embedded nut 23, the embedded steel pipe 22 and the embedded nut 23 are embedded in the fixing component of the bracket to be installed, the embedded nut 23 is arranged at the inner end of the embedded steel pipe 22 in the fixing component, and the embedded steel pipe 22 and the embedded nut 23 can provide an installing and detaching channel for the pin shaft 21 and are used for anchoring the pin shaft 21. Two ends of the pin shaft 21 are provided with T-shaped threads, the pin shaft 21 penetrates through the embedded steel pipe 22 and is in threaded connection with the embedded nut 23, the lower surface of the pin shaft 21 is closely attached to the lower pipe wall of the embedded steel pipe 22, and a gap is reserved between the upper surface of the pin shaft 21 and the upper close of the embedded steel pipe 22. The lower surface of the pin shaft 21 is closely attached to the embedded steel pipe 22, so that the pin shaft 21 can transmit the shearing force of the bracket structure 1 to the pipe wall of the embedded steel pipe 22, and then the shearing force is transmitted to a fixing component through the pipe wall of the embedded steel pipe 22, and the shearing force of the bracket structure 1 can be borne through the pin shaft nested structure 2.

In addition, the diameter ratio of the pin shaft 21 to the embedded steel pipe 22 inserted into the pin shaft 21 is 1.2, and because the diameter of the pin shaft 21 is smaller than that of the embedded steel pipe 22, a sufficient gap can be reserved so that the pin shaft 21 can be inserted into the embedded steel pipe 22 to be in threaded connection with the embedded nut 23, and friction between the surface of the pin shaft 21 and the inner wall of the embedded steel pipe 22 is avoided when the pin shaft 21 is rotated.

Further, embedded nut 23 sets up two, two at least along its axial embedded nut 23 is adjacent to be set up, two embedded nut 23 is screwing up the back, can produce axial force between the two, the increase frictional force between embedded nut 23 and the round pin axle 21 reaches and prevents the automatic mesh that takes off of embedded nut 23 improves then round pin axle 21 inserts stability in the embedded steel pipe 22 ensures the structural stability of this application bracket then.

The middle layer position of the mounting plate 11 of the bracket structure 1 is provided with a pin shaft through hole 111 for the pin shaft 21 to pass through, the pin shaft through hole 111 is symmetrically arranged on the vertical central line of the mounting plate 11, and the pin shaft through hole 111 can penetrate through two sets of the pin shaft nested structure 2, so that the bracket structure 1 can bear a large shearing force.

Simultaneously, the awl structure 3 of climbing that the 1 upper strata of bracket structure set up can be used for undertaking the moment of flexure of bracket structure 1, climb the preferred M36D 35 type that adopts of awl structure 3 and climb the awl, it includes that threaded connection buries a board 31, connecting screw 32 in proper order, climbs awl 33 and atress bolt 34, bury a board 31, connecting bolt and climb awl 33 and all pre-buried in fixed component, bury a board 31 and climb awl 33 and be tapering piece and little awl end relative setting between them, atress bolt 34 be used for with climb awl structure 3 with the mounting panel 11 locking of bracket structure 1 is fixed. The utility model provides a awl structure 3 that climbs all adopts the high strength material, through threaded connection between the part for the complete set combination climb awl structure 3 bearing capacity height, and pass through climb awl structure 3 and undertake bracket structure 1's moment of flexure, then improve the bearing capacity performance of this application bracket, improve the stability and the security of bracket.

Confession has been seted up on the mounting panel 11 upper strata of bracket structure 1 atress bolt 34 pass with climb the awl perforation 112 that awl 33 is connected, it is in to climb awl perforation 112 the upper strata of mounting panel 11 sets up threely, three climb the awl perforation 112 interval arrangement. Adopt many sets climb the synchronous atress of awl 33, can promote the bearing capacity of this application bracket by a wide margin.

The pre-buried structure of this application is still including locating the pre-buried dowel steel 4 of 1 lower floor of bracket structure, pre-buried dowel steel 4 mainly does bracket structure 1 provides the positioning action, mounting panel 11 lower floor of bracket structure 1 is equipped with the confession the dowel steel that pre-buried dowel steel 4 passed is perforated 113, just the dowel steel is perforated 113 department and is equipped with the confession pre-buried dowel steel 4 passes and rather than threaded connection's sleeve 114. The setting of sleeve 114 can be connected the mounting panel 11 with pre-buried dowel steel 4, the partial load that the bracket structure 1 received can by pre-buried dowel steel 4 undertakes, pre-buried dowel steel 4 can improve this application bracket and fixed component's joint strength.

Anchor bars in this embodiment perforate 113 with the vertical central line of mounting panel 11 sets up two symmetrically, can be through two pre-buried anchor bars 4 is right the position of bracket structure 1 is fixed a position, then improves this application bearing bracket mounted position's accuracy.

The utility model provides a bearing bracket is through setting up pre-buried structure, mainly passes through the shear force is undertaken to round pin axle nested structure 2, by climb awl structure 3 and undertake the moment of flexure, and by pre-buried anchor bar 4 comes right bracket structure 1 fixes a position, and the structure atress is clear and definite, and the whole bearing capacity of bracket structure 1 is strong. This application will in advance when the construction bracket climb awl structure 3, round pin axle nested structure 2, anchor bar and carry out pre-buried, pre-buried during round pin axle nested structure 2, earlier two pre-buried nut 23 threaded connection forms wholly, will again pre-buried steel pipe 22 and two pre-buried nut 23 is connected for whole, pre-buried steel pipe 22 with during the welding of pre-buried nut 23, need strict control pre-buried steel pipe 22's position to ensure at follow-up round pin axle 21 installation back, round pin axle 21's lower surface with pre-buried steel pipe 22's lower pipe wall is close to.
