Assembled type beam column node area reinforcing steel bar distribution structure

Abstract

The invention discloses an assembled type beam column node area reinforcing steel bar distribution structure. According to the distribution structure, an anchoring mode of precast beam longitudinal ribs in a beam column post-pouring area is optimized, middle beam bottom longitudinal ribs in a precast beam are mechanically connected in the beam column post-pouring area, beam bottom longitudinal ribs on the inner side of the precast beam are anchored to the beam column post-pouring area, precast column longitudinal ribs are distributed at the middle position and the corner positions of the column section, and collision between the precast column longitudinal ribs and the precast beam longitudinal ribs is avoided; thus, the precast column section is effectively reduced, the process and manufacture members are facilitated, member manufacturing cost is reduced, precast column weight is reduced, a precast member lifting and installing process is simplified, convenience is brought to installation, and a construction period and time cost are saved; in addition, the precast column section area is reduced, the building effective use area is further enlarged, and the building use quality is improved.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to an assembled beam-column node area reinforcement arrangement structure. Background technique [0002] Prefabricated buildings are buildings assembled from prefabricated parts and components on site. Due to their fast construction speed and low production costs, prefabricated buildings are widely promoted around the world. Prefabricated buildings will develop at an unprecedented speed and scale. [0003] At present, the rapid development of prefabricated building technology is seriously restricted due to some incomplete and unreasonable parts of prefabricated related specifications and atlases. Among them, in the "Technical Standards for Prefabricated Concrete Buildings" (GB / T51231-2016), please refer to figure 1 , figure 1 It is a schematic diagram of the prefabricated column structure in the existing code. In order to ensure that the prefabricated components are ho...

Problems solved by technology

[0003] At present, due to some incomplete and unreasonable parts of prefabricated related specifications and atlases, the rapid development of prefabricated building technology is seriously restricted.

Among them, in the "Technical Standards for Prefabricated Concrete Buildings" (GB / T51231-2016), please refer to figure 1 , figure 1 It is a schematic diagram of the prefabricated column structure in the existing code. In order to ensure that the prefabricated components are hoisted and the steel bars in the beam-column joint area do not collide, the prefabricated column 1 steel bars are distributed at the four corners, and the middle area is reserved for the anchorage of the longitudinal reinforcement at the bottom of the prefabricated beam. However, if this The layout scheme of the longitudinal reinforcement of the prefabricated column 1 will lead to the following problems: (1) the section of the prefabricated column 1 increases, which wastes resources and increases the cost of component manufacturing; Difficulty in hoisting; (3) The section of prefabricated column 1 increases, which reduces the effective use area of ​​the building and reduces the quality of use of the building

[0004] Therefore, how to solve the problems of large prefabricated column cross-section and high component manufacturing cost caused by the existing beam-column reinforcement arrangement structure is a technical problem that those skilled in the art need to solve at present.
