Description

Technical Field

[0001] The utility model belongs to the field of building mechanical and electrical installation engineering, and particularly relates to a stepless adjustable support and hanger structure. Background Technique

[0002] At present, the cross beam and the suspender of the support and hanger need to be connected and fixed through a connecting piece and a bolt. In actual use, due to the process error between the installation holes on the cross arm column and the installation holes on the connecting piece, normal assembly cannot be carried out. To solve this problem, at present, manufacturers set long holes or waist-shaped holes on the connecting piece to achieve position adjustment, but the bolts in these adjustment holes cannot be effectively locked, resulting in poor connection stability. Chinese patent document: CN202122731938.9, discloses an adjustable anti-torque connection structure of a support and hanger. In this application, two split connecting pieces are used to cooperate with the adjustment holes to fix the cross beam or the suspender. The adjustment hole is composed of three rhombic holes arranged in sequence. By matching this structure with a bolt with a square neck, the fixation between the connecting piece and the cross beam and the suspender is realized. Although this support and hanger can meet the requirement of adjustable installation position, in actual use, customers report that its adjustment range is still limited and there will be dead corners; and the assembly structure of using square steel to cooperate with the connecting piece causes its bearing capacity to be mainly concentrated on the connecting piece, thus affecting the bearing capacity of the support and hanger. Content of the Utility Model

[0003] Aiming at the above problems, the utility model discloses a stepless adjustable support and hanger structure, which can realize the stepless adjustment of the installation position of the cross beam, meet the installation requirements, does not need to use a connecting piece, and reduces the installation cost.

[0004] The specific technical solutions are as follows:

[0005] A stepless adjustable support and hanger structure includes a column, a cross beam and a connecting fastener. The cross beam is provided with installation holes arranged horizontally in sequence on both side surfaces. The columns are arranged at both ends of the cross beam. The cross section of the column is in a "C" shape structure, so that both ends of the cross beam are respectively embedded into the inner sides of the two columns, and the two side surfaces of the cross beam are attached to the inner walls of the two sides of the column; a plurality of adjustment holes are symmetrically arranged on the two side surfaces of the column from top to bottom. The adjustment hole is composed of a plurality of rhombic holes arranged longitudinally in sequence and communicated with each other, and a plurality of protruding limiting parts are formed on the inner walls of both sides of the adjustment hole; the position of the adjustment hole corresponds to the position of the installation hole, and the connecting fastener is horizontally penetrated.

[0006] The connecting fastener includes a square neck bolt, a nut and a locking piece. One end of the square neck bolt cooperates with the mounting hole and the limiting part in the adjusting groove through its square neck part to realize rotation limit. The other end of the square neck bolt passes through the column and the locking piece and is fixed by the nut. The locking piece fits tightly with the column under the pressure of the nut. Limit blocks are symmetrically provided at the upper and lower ends of one side of the locking piece. The two limit blocks are embedded in the adjusting hole and the mounting hole, and the limit blocks cooperate with the upper limit part on the inner wall of the adjusting hole and the mounting hole to realize limit fixation, so as to realize fixed connection between the beam and the column through the connecting fixing piece.

[0007] Furthermore, a through hole for the square neck bolt to pass through is provided in the center of the locking piece, one side of the locking piece is flat and fits with the nut, and a groove for accommodating the limiting part of the adjustment slot is provided between the two limiting blocks on the other side of the locking piece.

[0008] Furthermore, the left and right sides of the limit block are both inclined and adapted to the size and shape of the mounting hole and the adjustment hole.

[0009] Furthermore, the number of mounting holes on the crossbeam is at least two groups, the two groups of mounting holes are distributed up and down, and the positions of the two groups of mounting holes correspond to the positions of the upper and lower ends of the adjustment hole respectively.

[0010] Furthermore, the mounting holes are all diamond-shaped hole structures and are adapted to the size and shape of the diamond-shaped holes in the adjustment holes.

[0011] Furthermore, the number of the diamond-shaped holes arranged in the adjustment holes is not less than four.

[0012] The beneficial effects of the utility model are embodied in:

[0013] (1) The utility model sets an adjustment hole on the column, and the length of the adjustment hole is larger, which further improves the adjustable range of assembly, avoids the occurrence of bolt assembly dead angles, realizes the infinite adjustment of the installation position of the beam, and meets the installation requirements.

[0014] (2) Compared with the method of clamping and fixing the crossbeam and the column with connecting parts, the utility model uses the square neck part of the bolt and the limit block of the locking part to insert and fix the adjustment hole and the installation hole, so that the bearing capacity of the support and hanger bracket mainly depends on the shear force of the adjustment hole and the installation hole, so that the bearing capacity of the support and hanger bracket is mainly concentrated on the column, thereby ensuring the stability of the support and hanger bracket.

[0015] (3) Compared with the traditional method of fixing square steel beams and hangers with connecting parts, the utility model uses channel steel structure columns and beams for assembly, and only bolt fasteners and locking parts are used to fix the columns and beams. There is no need to use connecting parts, and the installation cost is lower. BRIEF DESCRIPTION OF THE DRAWINGS
