A dense rib branch-free system and its construction method

Abstract

The invention relates to a dense-ribbed branch-free system and a construction method thereof, comprising a support frame, a bottom formwork frame, a formwork shell, a prefabricated fixing part and a prefabricated steel cage, the bottom formwork frame is installed on the support frame, and the bottom formwork frame Formwork shells are placed in corresponding upper limit positions, and prefabricated reinforcement cages are installed between the adjacent formwork shells through prefabricated fixing parts to form a complete support-free formwork device. The invention has a simple structure, can be assembled on site, can be reused, and reduces construction costs. The formwork can make full use of the utilization rate of the limited formwork, and can fix the steel cage, formwork and bottom frame in an assembled manner. , and the fine-tuning of the column spacing is carried out through the movable formwork, and it is convenient to disassemble and fix, and can be recycled and used in the construction of densely ribbed beam floors.

Description

technical field [0001] The invention belongs to the technical field of building templates, and relates to the technology of densely ribbed beam formwork, in particular to a densely ribbed branch-free system and a construction method thereof. Background technique [0002] In the past ten years, concrete ribbed beam floors have been widely used in construction projects in my country. This type of floor has the characteristics of low height of floor structure, light weight of floor, less amount of cast-in-place concrete and steel bars, fast construction period, suitable for large-span structures, etc., so it is widely used in large shopping malls, exhibition halls, cultural and sports High-rise commercial and public buildings such as halls, warehouse buildings, libraries, underground structures, teaching buildings, office buildings, etc., especially commonly used in structural types with large space, large span, and high headroom requirements. [0003] However, the formwork la...

Problems solved by technology

[0003] However, the formwork laying in the prior art often adopts full pavement or strip paving, that is, laying the bottom form as a whole or at intervals under the formwork. Due to the lack of connection between the formwork, it is necessary to use bamboo plywood, wooden strips, extruded Fillers such as slats fill the gaps between the formworks to prevent the horizontal displacement of the formwork under the concrete side pressure, and generally after the formwork is laid, rib beams need to be laid between adjacent formworks Reinforcement cage, and fix it, so the above-mentioned series of processes make the formwork construction process cumbersome, and the formwork removal after pouring is complicated
