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 with reference to 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, the pipe end seal 2 closes the pipe body 1 to form a closed hollow pipe, and the pipe wall of the pipe body 1 has at least one glued joint of the slurry embryo body. The slit 3 is characterized in that there is a prefabricated sprue member 4 which is superimposed and glued together with the stitched embryo body at the junction of the embryo body of at least one joint seam 3, and the susceptor member 4 is a strip-shaped, flat plate, At least one of arc plate, T-shaped plate, V-shaped plate, reinforcing rib, stiffening rib plate, cross member, vertical member or plate member, and the joint seam 3 is the lap joint cementation of the embryo body or the embryo body. The body is butt-bonded or part of the lap joint of the embryo is butt-bonded. The pip...

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 an invention patent application with an application date of June 1, 2004, an 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 long-span and large-bay frame structure adopts the cast-in-place hollow floor technology, especially the beamless floor technology, which can shorten the construction period, reduce the cost, increase the usable space of the building, and reduce the white weight. , good seismic performance and so on. The hole-forming components used in beamless floors are permanent mandrels, such as paper tubes, plastic tubes, metal hollow tubes, and hard thin-walled tubes. These tubular mandrels or components mainly consider evacuated concrete to reduce the weight of the floor slab. Among them, paper tubes, plasti...
