Problems solved by technology

But the hollow tube member that above-mentioned various methods make is all more difficult at the seam joint part, and seam quality is poor, and the seam joint part overlap is not firm, thereby the strength of hollow pipe member, integrality are lower, and production efficiency is lower. Low

Embodiment Construction

[0054] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0055] As shown in the accompanying drawings, the present invention includes a pipe body 1, a pipe end seal 2, and the pipe end seal 2 closes the pipe body 1 to form a closed hollow pipe, and is characterized in that there is at least one material on the pipe wall of the pipe body 1 The joint seam 3 of the cemented joint of the plasma embryo body has a prefabricated supporting embryo member 4 which is superimposed and cemented with the joint embryo body at the joint position of the embryo body of at least one joint seam 3 . figure 1 It is a structural schematic diagram of Embodiment 1 of the present invention. In the accompanying drawings, 1 is the pipe body, 2 is the pipe end seal, 3 is the joining seam, and 4 is the support member. In the following drawings, those with the same number have the same description. Such as figure 1 As shown, the pipe en...

Abstract

This invention relates to a closed hollow pipe component, comprising pipe body(1), pipe end closure(2), the two of which form a hollow pipe. Wherein, there is at least one seam(3) glued by slip paste on pipe wall, characterized in that the idiosome adjoiner of at least one seam(3) has a precast embryophore unit glued with the conjugate idiosome to form a integrity. Hereby, it is easy to seam the conjugation site and firm to overlap, so the invention improves the production efficiency, and has lower cost and convenient construction and transportation.

Description

(1) Technical field [0001] The present invention relates to a closed hollow tubular member. (2) Background technology [0002] At present, in many buildings, the large-span and large-bay frame structure adopts the cast-in-place hollow floor technology, especially the beamless floor technology, which has the advantages of shortening the construction period, reducing costs, increasing the use space of the building, reducing the weight, Good anti-seismic performance and other advantages. 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 t...
