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

[0051] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0052] 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. The seam 3 is characterized in that there is a prefabricated support member 4 that is superimposed and glued with the joined embryo body at the joint part of the embryo body of at least one joint seam 3. The support member 4 is strip-shaped, flat, At least one of arc plate, T-shaped plate, V-shaped plate, rib, stiffened rib, horizontal bar, vertical bar, bar with plate or stiffened rib with plate, and the joint 3 is a blank Body lap joint cementation or embryo body butt joint cementation or embryo body partial lap joint part butt joint cementation joint joint, said pipe body 1 is provided with at least one of rods 6, stiffening ribs 7 or ribs 8, and the rods Part 6, s...

Abstract

The invention relates to a closed hollow pipe element, which comprises a pipe body (1) and a pipe end seal (2), wherein, the pipe end seal (2) seals the pipe body (1) to form a closed hollow pipe, and the pipe wall of the pipe body (1) is provided with at least one joint (3) glued by slurry and a blank body. The closed hollow pipe element is characterized in that: a blank body joint of the at least one joint (3) is provided with a preformed blank support element (4) which is glued and joined with the joined blank body into a whole; the blank support element (4) is at least one type among a batten, a flat plate, an arched plate, a T-shaped plate, a V-shaped plate, a reinforcing rib, a rib-stiffened plate, a crossbar member, a vertical bar member, a strip-board member or a strip-board rib-stiffened plate; and at least one among a member (6), a rib-stiffened plate (7) or a reinforcing rib (8) is arranged inside the pipe body (1). The closed hollow pipe element is suitable for being used in hollow floors, roofs, foundation slabs, walling or open bridges of various kinds of cast-in-situ reinforced concrete or prestressed reinforced concrete, and particularly suitable for being used in hollow girderless floors.

Description

[0001] This application is a divisional application of the invention patent application with the filing date of June 1, 2004, the application number of 200410155117.3, and the title of "A Closed Hollow Tube Member". (1) Technical field [0002] The present invention relates to a closed hollow tubular member. (2) Background technology [0003] 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 s...
