Mortise joint bearing supporting frame

Abstract

The invention discloses a mortise joint bearing supporting frame which comprises a vertical rod, horizontal transverse rods and inclined rods. The vertical rod is provided with connection seats, the connection seats are internally provided with automatic locking devices, the ends of the horizontal transverse rods and the ends of the inclined rods are provided with connection tenons, the connection tenons are arranged in the connection seats, the automatic locking devices fix the connection tenons, and the center lines of the horizontal transverse rods and the center lines of the inclined rods intersect at a point on the vertical rod center line. Mortise joint nodes are adopted, the ends of the horizontal transverse rods and the ends of the inclined rods are provided with the connection tenons, the connection tenons are inserted into the connection seats, the effects of being convenient to assemble and disassemble, safe and reliable are achieved, each node can be connected with 16 rod pieces at most, the center lines of the rod pieces intersect at one point, the result is completely consistent with calculation diagram assumption, the situation that the additional bending moment of the rod pieces is increased due to eccentricity, so that bearing force is lowered is avoided, meanwhile sporadic parts do not exist, and influences on the progress due to losing of the parts is avoided.

Description

technical field [0001] The invention belongs to the technical field of building structures, and in particular relates to a mortise joint load-bearing support frame. Background technique [0002] Although the traditional fastener-type steel pipe scaffolding is the most commonly used scaffolding at present, its construction efficiency is low. At the same time, the fasteners have defects such as easy deformation after long-term use, cracks or bolts slipping, and the load-bearing safety cannot be obtained. ensure. [0003] Although the portal-type steel pipe scaffolding has great innovation and improvement on the basis of the fastener-type steel pipe scaffolding, it has defects such as poor firmness of thin-walled components and poor horizontal force. [0004] The bowl buckle-type steel pipe scaffold has improved the bearing capacity and the mechanical performance of the nodes compared with the previous two scaffolds, but it has increased the cost. [0005] On the basis of inh...

Problems solved by technology

[0005] On the basis of inheriting the advantages of the above-mentioned various types of scaffolding, the plug-in steel pipe scaffold overcomes many defects. It is an upgraded product after the bowl button type and the original plug-in steel pipe scaffolding, but the number of rods connected to the nodes is limited. , and the horizontal and vertical slanting bars cannot be effectively connected, which affects the force of the support frame
