Concrete port bracing and preparation method thereof and special module

Abstract

The invention relates to a concrete port bracing integrating a port bracing with a PVC sleeve pipe positioned outside an opposite-pulling screw into an integer. The concrete port bracing is produced by fine gravel concrete through a module and a special machine, can firmly control the dimension of the section of a molding board by sufficiently utilizing the compression resistance of the fine gravel concrete and the tightening force of the opposite-pulling screw and can well enhance the engineering quality. The concrete port bracing needs to be internally added with longitudinal ribs or nets when bracing a length which exceeds a certain length so as to keep integrity during production and transportation, and the concrete port bracing can be normally used even if being thrown on the ground to be cracked; the concrete port bracing has a cylindrical surface, when a vibrating bar is inserted into the upper side of the concrete port bracing, the vibrating bar can smoothly slide off, and the outer surface of the concrete port bracing is provided with a groove or a notch so as to be beneficial to be combined with subsequent placing concrete to be placed and fixed. The concrete port bracing has the advantages of accurate appearance dimension, low cost, simple manufacture method, easy operation, high production efficiency and convenient industrial implementation.

Description

(1) Technical field: [0001] The invention relates to a concrete mouth brace, a manufacturing method thereof, and a special mold. It is an improvement to the building construction technology. (two) background technology: [0002] At present, in engineering construction, the commonly used method of controlling the section size of components is as follows: [0003] Column: According to the cross-sectional size formed by the binding of the column hoops and the main reinforcement, plus a protective layer of mortar pads or plastic pads, square wood is nailed to the back of the formwork to form an overall column formwork, and one or two pairs of pulls are worn in the middle of the column section at a certain distance Screw, screw covered with pvc pipe, square wood plus short steel pipe to form a column hoop, and the double-drawn screw clamps the steel pipe through the mountain-shaped card to fasten the formwork. [0004] Wallboard: According to the bound wallboard steel bars and ...

AI Technical Summary

Problems solved by technology

[0006] In view of the current construction technology, the cross-sectional dimensions of columns, walls, and beams cannot be well guaranteed, and due to the deformation of pvc pipes and anti-tension screws when vibrating concrete, many anti-tension screws cannot be pulled out and reused, which greatly increased cost
