A construction method for separate warehouse joints of concrete floor

Abstract

The invention discloses a construction method for the sub-compartment joints of the concrete floor, which adopts the integrated sub-compartment joints of galvanized plates to carry out the sub-compartment joint construction of the constructed concrete floor; The site-assembled sub-compartment joints assembled by straight sub-compartment joints and multiple cross-shaped sub-compartment joints; when constructing sub-compartment joints for the constructed concrete floor, the steps include: 1. Processing sub-compartment joints; 2. Measurement and release 3. On-site assembly of the joints in separate warehouses; 4. Binding of steel cages; 5. Overall pouring of concrete; 6. Filling of joints in separate warehouses. The present invention adopts the pre-processed flat and cross-shaped binning seams to assemble on-site to complete the on-site assembly type binning seams. The existing large-area concrete floors have problems such as long construction period, poor use effect, low anti-frost heave performance, and difficulty in guaranteeing construction quality.

Description

technical field [0001] The invention belongs to the technical field of warehouse-separated joint construction, and in particular relates to a construction method for divided warehouse joints of concrete floors. Background technique [0002] There are two types of joints: roof joints and ground joints. The roof joints are rigid roof joints to prevent deformation cracks. In order to prevent the roof waterproof layer from cracking due to temperature or structural deformation, roof joints are required. For warehouse joints, fill the joints with sealing materials such as asphalt-soaked wood wool boards, and fill the joints with ointment, etc., and cover the joints with waterproof membranes. Ground sub-warehouse joints are joints artificially divided to avoid cracking of cement and other materials when the ground is rigid and waterproof. They mainly exist in large-area poured concrete floors, such as large-area concrete floors such as factories, warehouses, and laboratories. At p...

Problems solved by technology

[0007] The technical problem to be solved by the present invention is to provide a method for the construction of concrete floor sub-storage joints in view of the deficiencies in the above-mentioned prior art. After the assembly is completed, the on-site assembly-type sub-compartment seams, the single-body sub-compartment joints used in the straight sub-compartment joints and the cross-shaped sub-compartment joints are all galvanized sheet sub-compartment seams, and the design of the galvanized sheet sub-compartment joints is reasonable and the use effect is good It can effectively solve the existing problems of long construction period, poor use effect, low anti-frost heave performance, and difficulty in guaranteeing construction quality in the construction of large-area concrete floors.
