Assembly type dismounting-free formwork and manufacturing method thereof

Abstract

The invention discloses an assembly type prefabricated dismounting-free formwork. The assembly type prefabricated dismounting-free formwork is characterized in that a prefabricated integral formwork and a dismounting-free form body are involved, wherein the prefabricated integral formwork comprises transverse steel components and longitudinal steel components, the transverse steel components and the longitudinal steel components are welded into a frame, the lower surface of the prefabricated integral formwork formed by welding is a reference plane, the dismounting-free form body is laid on thereference surface side of the prefabricated integral formwork, and the dismounting-free form body is fixedly connected with the prefabricated integral formwork through fasteners. The invention further discloses a manufacturing method of the dismounting-free form system. According to the assembly type prefabricated dismounting-free form and the manufacturing method, the advantages that the structure is simple, machining is facilitated, the construction efficiency is improved, the rigidity is good, machining is easy and the like are achieved.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to an assembled formwork without dismantling and a manufacturing method thereof. Background technique [0002] At present, there are mainly two types of floor slabs for buildings, one is prefabricated slabs, and the other is cast-in-place concrete slabs. The prefabricated slab floor is installed by prefabricating on the ground and hoisting on site. The advantage is that the construction progress is accelerated and the cost is low. However, there is no effective connection between the existing prefabricated slab floor and the wall. When encountering natural disasters such as earthquakes, it is easy to loosen and fall off, causing property damage and even casualties. In addition, after the existing prefabricated slabs are assembled, there are certain gaps between the slabs, and improper handling will cause cracks in the ceiling, which not only affects the...

Problems solved by technology

During the construction of prefabricated residential buildings with steel trusses and galvanized bottom formwork, there are problems with welded steel truss floor decks: a) It is difficult to remove the galvanized bottom formwork from the bottom of the slab; b) Corrosion of the steel truss footing affects the roof Decoration; c) The foot of the steel truss will sag and deform when the galvanized formwork is removed, which will affect the whitewashing at the bottom of the floor; d) The labor intensity is high and the labor cost is high; During the construction process, the prefabricated reinforced truss floor deck has the following problems: a) the use of thicker galvanized steel formwork greatly increases the cost of materials; b) the connection between the reinforced truss and the bottom formwork is inefficient. ; c) The number of repeated use of galvanized templates and connectors is relatively low; d) There are problems of large labor, high labor costs and high labor intensity
