A joint construction method of a figure-eight steel-concrete transfer truss composite structure

Abstract

The invention discloses a construction method of a figure-eight steel-concrete conversion truss composite structure node, which comprises the following steps: a) opening pouring holes in sections in advance on the side formwork; b) pouring concrete through the pouring holes, and adopting flat plate vibration during the pouring process The concrete is vibrated outside the formwork with the vibrator; c) During the vibrating process, the reinforcement slats set outside the formwork are excited by the plate vibrator, and the formwork is excited at the same time; d) After the pouring is completed, use After the cover plate blocks the pouring hole, another pressure plate is added on the outside to cover it, and it is reinforced with card ribs. Through the unitized design of the vibrating part, the plate vibrating device can better adapt to the unevenness of the formwork reinforcement slats, improve the vibrating effect, and use the external vibration of the formwork to improve the compactness of the concrete at the complex joints. Good construction convenience features.

Description

technical field [0001] The invention belongs to the technical field of building construction equipment, and in particular relates to a node construction method of a figure-eight steel-concrete conversion truss composite structure. Background technique [0002] Concrete pouring is a major difficulty in construction due to the dense reinforcement at the joints between reinforced concrete beams and steel column corbels. It is difficult for traditional vibrating devices to penetrate into it for vibrating, and the use of flat vibrator is easy to cause uneven vibration. Patent No. CN201820954211.2 discloses a flat vibrator, which solves technical problems such as uneven vibration of the existing flat vibrator. The vibrator includes a vibrating base plate and a vibrating motor. The vibrating base plate is made of white iron. Two connecting bars are fixed on the upper surface of the vibrating base plate. The two connecting bars are arranged in parallel, and the two connecting bars a...

Problems solved by technology

[0003] However, in the specific construction, since the building formwork needs to be fixed with many horizontal and vertical slats around it when it is supported and fixed, there are problems of uneven spacing between the slats and uneven height of the slats. , when the traditional plate vibrator is vibrating, it is difficult for the plate to fit all the fixed slats perfectly, resulting in some slats vibrating and some slats not vibrating when vibrating. The plane vibrating effect is better, but it cannot solve the problem of vibrating uniformity caused by the unevenness of the fixed slats
