Assembly type underground pipe gallery upper section steel bar and manufacturing method

Abstract

The invention relates to an assembly type underground pipe gallery steel bar and a manufacturing method, is designed for achieving rapid manufacturing and installing of a assembly type pipe gallery steel bar, and belongs to the field of building materials. The steel bar is characterized in that a pipe gallery top plate longitudinal steel bar is orthogonally and fixedly connected with a pipe gallery top plate transverse steel bar to form an upper layer steel bar net piece and a lower layer steel bar net piece, the pipe gallery top plate steel bar is formed through pipe gallery top plate pull-upribs, and the two longitudinal sides of the pipe gallery top plate steel bar are perpendicularly intersected with a pipe gallery upper section side wall vertical reinforcing steel bar; and a pipe gallery upper section side wall horizontal longitudinal steel bar is perpendicularly intersected and fixedly connected with the pipe gallery upper section side wall vertical reinforcing steel bar, a pipegallery upper section side wall inner-layer steel bar net piece and a pipe gallery upper section side wall outer-layer steel bar net piece are formed correspondingly and are connected into a pipe gallery upper section side wall steel bar through side wall pull-up ribs, the upper portions of the two pipe gallery upper section side wall steel bars are perpendicularly intersected and fixedly connected with the pipe gallery top plate steel bar, and the lower portions are connected with a pipe gallery upper section side wall tongue-and-groove steel bar to form the pipe gallery upper section steelbar. The provided assembly type underground pipe gallery upper section steel bar is a framework of the upper section of an underground pipe gallery, and plays an important role in manufacturing and installing the upper section of the pipe gallery.

Description

technical field [0001] The invention relates to a steel bar in the upper section of an assembled underground pipe gallery and a manufacturing method, which is designed for the rapid manufacture and installation of steel bars in an assembled underground pipe gallery, and belongs to the field of building materials. Background technique [0002] In order to solve the serious waterlogging problem in urban rainy seasons, the country is promoting underground pipe corridors to solve the problem of long-term chaotic installation of underground pipes in my country and difficult urban drainage in rainy seasons. This is a major strategic measure. At present, the national decision-making Pilot installation of underground pipe corridors in cities, and after gaining experience, it will be promoted and used in cities across the country. [0003] my country has used underground pipe galleries in the construction of large factories. These underground pipe galleries are all constructed with ca...

Problems solved by technology

[0003] my country has used underground pipe galleries in the construction of large factories. These underground pipe galleries are all constructed with cast-in-place concrete pipe galleries. The construction process is long, all of which are wet operations, and the labor intensity of the operators is high. With the acceleration of globalization, most of the migrant workers who are construction workers have reached the age of retirement or are close to retirement, while most of the new labor force is graduates of colleges and technical secondary schools, who are unwilling and impossible to take over the past migrant workers to work in the construction industry. The most effective way to solve the above problems is to promote the factory production and on-site installation of building parts and components; the existing pipe gallery steel bars are produced and installed at the construction site, with low production precision, long installation time, and heavy workload for operators , labor-intensive, not suitable for modern construction requirements
