Embodiment Construction
[0025] A construction method for pouring a concrete wall panel by using a steel-plastic crack-resistant grid net is characterized in that it includes the following steps:
[0026] 1) Typesetting according to the length, thickness and height of the concrete wall panel, and draw a layout map; select a two-way steel-plastic geogrid, and set a single-layer steel-plastic geogrid on both surfaces of the concrete wall panel, and the steel-plastic geogrid The amount is calculated according to the contact area with the concrete wall panel, and the amount of steel-plastic geogrid material is calculated; the width of the steel-plastic geogrid is 2m, 4m, 6m (the conventional width of the steel-plastic geogrid is 2m, 4m, 6m etc., according to the height and width of the actual concrete wall panels);
[0027] 2) According to the design requirements of the concrete wall panel, check and accept the structural reinforcement of the concrete wall panel; at the same time, purchase the raw materia...

Abstract
The invention provides a method for constructing concrete wallboard in a pouring mode through steel-plastic anti-crack grilles and belongs to the technical field of building construction. The method is characterized by comprising the steps that the positions of steel-plastic geogrids are controlled through bar spacers on the two sides of the concrete wallboard; one end of each bar spacer is used for binding the steel-plastic geogrids, and the other ends of the bar spacers are welded to steel bars of the concrete wallboard, so that the steel-plastic geogrids are located accurately, and the steel-plastic geogrids and the concrete wallboard form a composite interlocking system; finally, concrete is poured. According to the method, the steel-plastic geogrids are arranged in the super-long and super-thick reinforced concrete wallboard, the purchase expenses are low, construction operation is easy and convenient, installation operation can be completed just through small tools, the construction cost is low, and the method is easy to popularize and apply and has obvious economic benefits and social benefits.
Description
technical field [0001] The invention relates to a technology for anti-cracking and anti-seepage of reinforced concrete wall panels in engineering construction, in particular to a construction method for anti-cracking and anti-seepage of super-long and ultra-thick reinforced concrete wall panels. The invention discloses a construction method for pouring concrete wall panels with split grid nets, belonging to the technical field of building construction. Background technique [0002] Concrete is currently the most widely used building material in construction engineering, but concrete is prone to brittle cracks due to shrinkage. It directly affects the use function of buildings and structures with high requirements for anti-cracking and anti-seepage. Therefore, the cracks and leakage of reinforced concrete structures have become a major problem that plagues the quality of reinforced concrete structures. Contents of the invention [0003] The purpose of the present invention...
