Method for manufacturing three-arc thin-wall box

Abstract

The invention relates to a method for manufacturing a three-arc thin-wall box, in particular to a method for manufacturing a thin-wall box provided with four arc sides in a cast-in-situ hollow building floor slab. A main body mold and a side mold are included; the main body mold comprises a substrate, and a front frame, a top frame, a rear frame and a bottom frame fixed on the substrate; when thesubstrate is folded, the front frame and the bottom frame are fixed together; a mode of coating the whole substrate by one step is utilized to form the four faces of the thin-wall box; and a mode of folding the substrate is utilized to form the thin-wall box with the arc sides. Four-side boards of the thin-wall box are made of the whole substrate to integrally form a main body frame of the thin-wall box with high pressure resistance; by utilizing the distances among the frames, the substrate is bent to form the arc sides between two boards of the thin-wall box; the frames made of square steelhave the advantages of light weight and easy operation; and the substrate can be made of a whole iron sheet, and also can be formed by riveting a plurality of iron scraps so as to save cost.

Description

technical field [0001] The invention relates to a manufacturing method of building materials, in particular to a manufacturing method of a thin-walled box body with three arc-shaped sides in the floor of a cast-in-place hollow building. Background technique [0002] At present, a hollow thin-walled box is placed in the floor of the cast-in-place building to form a hollow layer of the floor. The thin-walled box generally has six sides. Each surface of the wall box, and then use adhesives or mortar to glue the parts together to form a complete thin-wall box. When the panels are combined together, the stress strength of each place is uneven, and due to the The limitation of the thin-walled box will also lead to problems such as inconsistent shape and poor sealing, which will affect the layout of the floor, and a single panel is easily damaged during the process of handling and assembly. There are holes on the side of some thin-walled boxes for connection between thin-walled bo...

Problems solved by technology

[0004] In order to solve the problem in the prior art that the mold structure for making thin-walled boxes is unreasonable, resulting in uneven stress on the produced thin-walled box and the problem that it cannot be in close contact with the floor, the invention provides an arc-shaped thin-walled box The manufacturing method, the specific scheme is as follows: a manufacturing method of a three-arc thin-walled box, including a main body mold and a side mold, the main body mold includes a base plate, a front frame fixed on the base plate, a top frame, a rear frame and a bottom frame Frame, the top frame and the bottom frame have a support seat on one side close to the rear frame, the base plate is a rectangular plate made of elastic material, and there is no contact between the frames on the base plate, and the side mold includes a left side plate and a right side The plate and the reinforcements respectively fixed on it, the middle part corresponding to the top frame and the bottom frame on the base plate has a hole connecting the through channel, which is characterized in that the following steps are adopted:
