Abstract

The invention relates to the technical field of building components, and particularly relates to a T-shaped joint reinforced by local grouting of a base plate. The T-shaped joint comprises a main pipe and a branch pipe which are connected in a non-parallel mode, wherein the base plate is arranged at the joint of the main pipe and the end of the branch pipe; with the base plate as the boundary, the main pipe comprises a first branch pipe and a second branch pipe; the first branch pipe, the second branch pipe and the branch pipe are each internally provided with a sealing plate; a grouting cavity is formed among the three sealing plates; the main pipe or / and the branch pipe is / are provided with a grouting hole / grouting holes for grouting concrete into the grouting cavity; and the grouting cavity is filled with concrete grouted through the grouting hole / grouting holes. According to the T-shaped joint, the bearing capacity of the joint is improved by additionally arranging the base plate at the joint, and the ductility of the joint is improved; local grouting is conducted on the main pipe through the grouting hole, and the bearing capacity of the joint is improved on the premise of keeping the self weight; and the T-shaped joint is high in working stability, long in service life, high in practicability, good in using effect and convenient to apply and popularize.

Description

technical field [0001] The invention relates to the technical field of building components, in particular to a T-shaped joint reinforced by partial grouting of a backing plate. Background technique [0002] The pipe structure is a joint form formed by welding a branch pipe with a smaller diameter and a main pipe with a larger diameter. The steel pipe (pipe truss) structure has the advantages of beautiful appearance, good overall performance, light weight, strong torsional rigidity, good fire resistance, convenient manufacturing and construction, full use of the strength of the material itself, and its superior economy. It is widely used in common building structures such as modern industrial plants, warehouses, gymnasiums, towers, bridges, exhibition halls, venues, marine working platforms, terminal buildings, stations and office buildings. [0003] At present, the intersection of rectangular steel pipes in the project is mainly connected by intersecting nodes, that is, the...
