A construction method of hangar concrete surface structure

Abstract

The invention relates to a hangar concrete surface layer structure and a construction method thereof. The hangar concrete surface layer structure comprises concrete unit blocks, wherein a group of concrete unit blocks are provided and are arranged in a matrix shape, the longitudinally adjacent concrete unit blocks are separated by transverse separation seams, first grooves are formed in the side faces of the concrete unit blocks on one sides of longitudinal separation seams, first protrusions are arranged on the side faces of the concrete unit blocks on the other sides of the longitudinal separation seams, the first protrusions are inserted into the first grooves, the edges of the concrete unit blocks are provided with steel angle beads correspondingly, the cross sections of the steel angle beads are inverted-L shaped, connecting holes are formed in the vertical edges of the steel angle beads, the steel angle beads on the two sides of the longitudinal separation seams are connected through bolts, the longitudinal separation seams are filled with foam boards, and the positions, located between the corresponding steel angle beads, at the upper portion of each longitudinal separationseam is filled with a sealing strip. According to the hangar concrete surface layer structure and the construction method thereof, the technical problems that the traditional steel angle bead installation and reinforcement are difficult, steel bars are wasted, the flatness and the straightness of the steel angle beads are difficult to guarantee, the construction process of the steel angle beads iscomplex, and the construction progress is relatively slow are solved.

Description

technical field [0001] The invention belongs to the field of building engineering construction, in particular to a construction method for a hangar concrete surface structure. Background technique [0002] The floor of the hangar hall of a certain project is a 400mm thick cast-in-place reinforced concrete floor, with a total area of ​​14655.9㎡ and a plane size of 147×99.7m. During the pouring process of the floor concrete surface, it is necessary to set up longitudinal joints, and set steel corner guards at the top corners of the longitudinal joints. The traditional angle steel corner is fixed by welding the anchor bar and the measure steel bar. This setting method has the difficulties of installing and reinforcing the angle steel, wasting steel bars, and it is difficult to guarantee the flatness and straightness of the angle steel corner. The construction process of the angle steel corner is complicated and the construction progress The downside of being slower. Contents...
