Steel tube support and flange-type node connecting device of same

Abstract

The invention discloses a steel tube support and a flange-type node connecting device of the same. The steel tube support comprises an upright, horizontal rods, a planar inclined rod, a facade inclined rod and the node connecting device, wherein the node connecting device is composed of a flange disk socket, horizontal rod spigots, a planar inclined rod spigot, a facade inclined rod spigot and bolts; and the flange disk socket is composed of an upper disk, a lower disk, connecting rods, upper disk inclined rib heads and lower disk inclined rib heads. The steel tube support adopts the flange-type node connecting device; the node connecting device is stable and firm; node rotation rigidity is high, so reliable lateral supporting effects are provided by the horizontal rods to the upright, andupright stability is enhanced; under normal load bearing, the bolts can automatically move downwards for locking immediately after getting loose; and under abnormal load bearing, when the bolts moveupwards, relative horizontal slide of the socket and the spigots can limit vertical motion of the bolts and realize node self-locking, so that reliability of a support body is ensured, and hidden safety dangers are eliminated.

Description

technical field [0001] The invention relates to a bracket and a node connection device thereof, in particular to a steel pipe bracket and a flange-type node connection device thereof, and belongs to the technical field of steel tube brackets. Background technique [0002] The steel pipe bracket is a vertical support system for engineering formwork, and the common forms include fastener type, bowl type, socket type, and so on. [0003] In the process of actually using the steel pipe support, we found that the existing steel pipe support has certain deficiencies, such as: [0004] (1) Fastener-type steel pipe support: In the process of erection, affected by the instability of human operation, it is easy to appear that the joint fastening is not up to standard, which leads to poor reliability of the frame body; the frame body accessories are easy to be lost; assembly and disassembly efficiency Low, it is difficult to meet the needs of high formwork engineering safety and opera...

Problems solved by technology

[0004] (1) Fastener-type steel pipe support: In the process of erection, affected by the instability of human operation, it is easy to appear that the joint fastening is not up to standard, which leads to poor reliability of the frame body; the frame body accessories are easy to be lost; assembly and disassembly efficiency Low, it is difficult to meet the needs of high formwork engineering safety and operability of assembly and disassembly space;

[0005] (2) Bowl buckle-type steel pipe support: the nodes are easily damaged, and oblique rod connections cannot be provided. Usually, fastener-type steel pipes are mixed and matched, which makes it difficult to ensure the reliability of the frame body; the assembly and disassembly efficiency is low, and it is difficult to adapt to the safety and security of high formwork engineering. Requirements for the operability of assembly and disassembly space;

[0006] (3) Socket-type buckle-type steel pipe support: Although the performance of the support body is superior to other products, due to the complexity of the building shape of high-support formwork engineering, the variable spacing of the vertical poles causes the erection angle of the plane inclined poles to not be completely 45° , the frame is difficult to flexibly realize the reliable connection of the plane inclined rods, and the fastener-type steel pipes are usually used to mix and match the knots, which makes it difficult to ensure the reliability of the frame
