Formwork for pouring concrete structures and pouring construction method

Abstract

The invention provides a formwork for pouring concrete structures, which comprises two side formworks, a tie mechanism for tying the knots between the two side formworks, vertical keels and horizontal keels placed outside each side formwork, and two side formworks Between them is the concrete pouring area. Each side formwork includes steel formwork and square wood. The square wood has embedded parts piercing holes and bolt holes that go through the square wood. The bolt holes are vertically arranged with the embedded parts piercing holes. Corresponding to the bolt holes on the two adjacent steel formworks of the wooden square, the wooden square and the two adjacent steel formworks are connected by bolts. The tie mechanism includes tie rods, nuts and mountain-shaped pieces. The tie rods include sequentially connected threaded sections, flat sections, Steel bar section, flat section and thread section, the length of the steel bar section is equal to the thickness of the concrete pouring area, the flat section is placed between two adjacent steel formworks and the gap between the two steel formworks is equal to the thickness of the flat section, and the transverse keel is limited to the mountain type card slot. The invention also provides a concrete structure pouring construction method.

Description

technical field [0001] The invention relates to a template for pouring concrete structures, and also relates to a construction method for pouring concrete structures. Background technique [0002] At present, the common construction method of reinforced concrete structures is to use wooden formwork for integral pouring construction. The specific method is: after the cushion concrete is poured, the steel bars are bound, and after the bottom plate and side wall steel bars are bound, the bottom plate, side wall wooden formwork support and Scaffolding is supported by piercing and fastening the pull bolts. The embedded parts are drilled and pre-embedded to complete the formwork reinforcement and the installation of the embedded parts. pouring. Both the pre-embedding process of drilling embedded parts and the perforation and fastening of pull bolts need to open holes through the wood formwork on the wood formwork, resulting in a decrease in the strength of the wood formwork, and ...

AI Technical Summary

Problems solved by technology

Both the pre-embedding process of drilling embedded parts and the perforation and fastening of pull bolts need to open holes through the wood formwork on the wood formwork, resulting in a decrease in the strength of the wood formwork, and the wood formwork itself has the disadvantages of easy deformation and large deformation. The fastening force directly acts on the wooden formwork. These factors not only lead to quality problems such as tympanum, grout leakage, and poor quality of embedded parts when pouring concrete, but also cause waste of formwork, which does not meet the requirements of energy conservation and environmental protection. It shortens the use turnover cycle of the formwork, increases the production cost, and prolongs the construction period
