Description

Technical Field

[0001] The utility model relates to the technical field of construction brackets, in particular to a construction bracket assembly. Background Art

[0002] In the process of construction, whether it is building a building, a workshop, or a road or a bridge, construction supports are indispensable. Currently, most of the supports used are wooden supports and steel pipe supports. Construction supports are mainly used for personnel to climb up for construction or to lift materials to high places.

[0003] Existing Figure 1 The construction support shown uses a scissor-type connecting rod to connect, assemble and position the vertical support tube (rod). During the assembly and installation, the four ends of the scissor-type connecting rod need to be connected and fixed to the vertical support tube. However, the upper and lower mechanisms on the vertical support tube for positioning the scissor-type connecting rod are separately and independently arranged, and there is a lack of a structure that can be driven synchronously for tightening and loosening. As a result, when the scissor-type connecting rod is disassembled and assembled, it is necessary to tighten and loosen the two positioning mechanisms in steps, which is inconvenient to operate and use, reducing the efficiency of disassembly and assembly of the construction support. Utility Model Content

[0004] In view of this, the utility model provides a construction support assembly to solve the problem that the upper and lower mechanisms for positioning the scissor-type connecting rod on the vertical support rod are separately and independently arranged, and there is a lack of a structure that can be driven synchronously for tightening and loosening. As a result, when the scissor-type connecting rod is disassembled and assembled, the two positioning mechanisms need to be tightened and loosened in sequence in steps, which is inconvenient to operate and use.

[0005] The technical solution proposed by the utility model is: a construction support assembly, specifically comprising an upright support frame and a scissor-type connecting rod; the upright support frame as a whole is composed of two upright support pipes and two horizontal reinforcing rods symmetrically welded between the two upright support pipes, and the scissor-type connecting rod is installed between the two upright support frames;

[0006] Two positioning columns are symmetrically welded at the upper and lower ends of the vertical support tube, and a shaft ring is welded at each of the four ends of the scissor-fork connecting rod, and the shaft ring is sleeved and matched with the positioning column; two vertical sliding grooves are symmetrically opened at the upper and lower ends of the vertical support tube, and two L-shaped positioning shafts are symmetrically welded at the upper and lower ends of the vertical support tube; two L-shaped plug rods are symmetrically slidably installed on the two L-shaped positioning shafts through pushing, and the horizontal part of the L-shaped plug rod is slidably matched with the vertical sliding groove, and the vertical part of the L-shaped plug rod is slidably matched with the positioning column, so as to fix the scissor-fork connecting rod on the vertical support tube;

[0007] The middle part of the vertical support tube is rotatably installed with a screw driving member, which is composed of a knob shaft and three reels welded on the knob shaft at equidistant intervals, and the three reels are located inside the vertical support tube; two steel wire ropes are wound between the three reels, and the head ends of the two steel wire ropes are rotatably connected to the upper and lower L-shaped rods; the L-shaped rod and the positioning column together constitute a plug-in positioning mechanism for the head end of the scissor-fork connecting rod; the spring on the L-shaped positioning shaft is used to rebound and drive the L-shaped rod to slide back and reset, and indirectly pull and drive the screw driving member to rotate and reset, and under normal circumstances, the spring on the L-shaped positioning shaft is used to push the L-shaped rod to be held on the positioning column; through the two steel wire ropes and the springs on the two L-shaped positioning shafts, the forward and reverse rotation of the screw driving member can synchronously pull and drive the two L-shaped rods to slide towards each other, so as to complete the tightening and loosening of a vertical support tube and the scissor-fork connecting rod at one time.

[0008] Furthermore,

[0009] A ladder is welded between the two horizontal reinforcement bars.

[0010] Furthermore,

[0011] The ladder is arranged vertically.

[0012] Furthermore,

[0016] Furthermore,

[0017] Two annular spaces are formed between the three reels.

[0018] Furthermore,

[0019] The two steel wire ropes are wound in two annular spaces, and the rotation directions of the two steel wire ropes are opposite.

[0020] The utility model provides a construction support assembly, which has the following beneficial effects:

[0021] When the utility model is in use, the two steel wire ropes are used in conjunction with the springs on the two L-shaped positioning shafts. The forward and reverse rotation of the screw driving part can synchronously pull and drive the two L-shaped insertion rods to slide and insert toward each other, thereby completing the tightening and loosening of a vertical support tube and a scissor-type connecting rod at one time. Compared with the prior art that lacks a synchronous driving structure between the two positioning mechanisms on a vertical support tube, the trouble of tightening and loosening the two positioning mechanisms in sequence when disassembling and assembling the scissor-type connecting rod can be eliminated. The operation is convenient and useful, which helps to improve the efficiency of disassembling and assembling the construction support.

[0022] In addition, two steel wire ropes are wound in two annular spaces, and the rotation directions of the two steel wire ropes are opposite. The two steel wire ropes are hidden and installed inside the vertical support tube in a relatively independent and closed space, which can avoid direct and long-term exposure to air and easy moisture oxidation. It helps to extend the service life of the steel wire ropes, reduce the number of maintenance and replacement of the steel wire ropes and the workload, and is easy to use.
