Embodiment Construction

[0010] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0011] figure 1 A schematic diagram of a steel member in normal use, with the steel member straight and free from bending or twisting. figure 2 For the steel member 1 that is integrally bent, the steel member 1 is bent so that the entire steel member 1 forms an arc. The straight sleeve 2 is set within the bending range of the steel member 1. During installation, the straight sleeve 2 can be cut into two parts in the axial direction in advance, and the two parts of the straight sleeve are respectively buckled outside the steel member 1 and assembled On-site connection, the connection method can be existing connection methods such as welding or bolts, and of course other methods can also be used to cover the casing 2 outside the steel member 1. The construction accuracy of the suit is not high, and it only needs to be inserted with a str...

Abstract

The invention relates to an overall reinforcing grouting steel casing pipe of a steel member, relating to the field of steel structure engineering of fixed buildings and aiming at reinforcing the overall bending or twist of steel members. A straight casing pipe is axially sleeved on the steel member having overall buckling; and the swelling cement paste is filled between the straight casing pipe and the steel member. Aiming at overcoming the problem that the structure security and the normal use function of the steel member are influenced during the construction period in the prior art, the invention provides the overall reinforcing grouting steel casing pipe; by using the overall reinforcing grouting steel casing pipe, the bearing capability and the rigidness of the original steel members are improved; and meanwhile the partial reinforcing grouting steel casing pipe has the beneficial effects of low construction requirements on precision, construction convenience and short working period.

Description

technical field [0001] The invention relates to the field of fixed building structure engineering, in particular to a sleeve used for reinforcing the overall bending or twisting of steel components. Background technique [0002] Steel components are linear in normal use, but in actual engineering, steel components often distort as a whole. The current reinforcement method is to cut, replace or weld plate reinforcement on the original component, which will affect the original component. The load-bearing performance of the building affects the safety and normal function of the building during the reinforcement construction. Moreover, it is necessary to install and support the original components during reinforcement, which leads to problems such as long reinforcement period, high cost, and high construction precision requirements. Contents of the invention [0003] In order to overcome the problem that the structural safety and normal use function of the prior art are affec...
