AI Technical Summary

Technical Problem

The existing roof joint construction methods have problems such as uneven concrete thickness, difficult to master the strength of the cut joints due to settlement of anti-crack wire mesh, and unstable bonding of the extruded plate, resulting in uneven joints and difficult to control the thickness.

Method used

A roof waterproof layer lattice construction method is adopted, including laying a waterproof layer on the roof, performing joint planning and pre-setting, using pads and corner strips to support the extruded plate, and using gravity and vibration of the drum to compact it when pouring concrete. After the maintenance period expires, the extruded plate is removed and the joint filling is filled.

Benefits of technology

The smoothness, accuracy and beauty of roof joints are achieved, ensuring the straightness and thickness uniformity of joints are ensured, building costs are reduced, and construction accuracy and effect are improved.

Abstract

The invention relates to the field of roof building construction, in particular to a roof waterproof layer gridding construction method which comprises the following steps that S1, a waterproof layer is laid on a roof, and after the waterproof layer is dry and fixed, the waterproof layer is subjected to acceptance inspection; s2, parting planning is carried out on the roofs qualified in waterproof layer acceptance inspection, and the positions and sizes of parting of the roofs are determined; s3, according to the position of the parting, a cushion block is fixed to the waterproof layer to serve as a support, and an angle bead is fixed to the cushion block according to the position of the parting; s4, the length, the width and the height of the extruded sheet are adjusted according to the size of the roof parting, the extruded sheet is installed on the angle bead, and parting presetting is completed; s5, concrete pouring is conducted on the waterproof layer of the roof, the pouring height of the concrete is made to be flush with the height, installed on the corner beads, of the extruded sheet, compaction is conducted on the concrete through the gravity and vibration of a roller, gaps and bubbles in the concrete are reduced, redundant moisture and air in the concrete are discharged, and a smooth and uniform concrete surface is formed; and S6, after the maintenance expires, the extruded sheet is removed, a parting joint with the smooth surface is obtained, and the parting joint is fully filled with joint filler.
