Press mould molding tube

Abstract

The invention relates to a press mould formed pipe, comprising at least two half pipes (1) which are connected together. The press mould formed pipe is characterized in that: the half pipes (1) are formed by pressing base materials placed in a mould; the edges of the half pipes (1) are provided with connecting edges (2); and the two half pipes (1) are connected to form the closed press mould formed pipe through the connecting edges (2). The press mould formed pipe can be applied to various constructions such as cast-in-place slab floors, roofs, walls, foundation mats and road and bridge works, and is especially suitable for hollow flat slabs.

Description

(1) Technical field [0001] The present invention relates to a compression molded tube. (2) Background technology [0002] At present, in many buildings, the large-span and large-bay frame structure adopts the cast-in-place hollow beamless floor technology, which has the advantages of shortening the construction period, reducing costs, increasing the usable space of the building, reducing its own weight, and good seismic performance. The hole-forming components used in beamless slabs are permanent mandrels, such as paper tubes, plastic tubes, metal hollow tubes, hard thin-walled tubes, etc. These tubular mandrels or components are mainly considered to evacuate the concrete and reduce the weight of the floor slab. Among them, paper tubes, plastic tubes, and metal hollow tubes are rarely used because of their high cost. At present, most of the projects use hard thin-walled tubes, such as the "fiber-reinforced thin-walled tube for filling cast-in-place reinforced concrete" wit...

AI Technical Summary

Problems solved by technology

This method has low production efficiency, complex process, low wall strength and easy damage. Therefore, it is urgently needed to develop a compression molded tube.
