Embodiment Construction

[0049] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0050] As shown in the accompanying drawings, the present invention includes a hollow pipe body 1, a stiffener 2, and a plug 3. The stiffener 2 is arranged in the cavity of the hollow pipe body 1, and the plug 3 is closed at both ends of the hollow pipe body 1. At least one of the pipe body 1, the stiffener 2, and the plug 3 contains a reinforcement 4, which is characterized in that at least one of the hollow pipe body 1, the stiffener 2 or the plug 3 is provided with at least one laminated layer 5, and the laminate The composite layer 5 is arranged on the pipe wall or / and the plug at the junction of the hollow pipe body 1 and the plug 3 . Reinforcement 4 can be silk, tendon slender member, or silk, tendon slender member weaving or woven cloth and net, or non-woven adhesive cloth, net, or a combination of the two or more, such as reinforcement 4 can be ...

Abstract

The present invention relates to a thin-wall pipe for pouring concrete. It includes hollow pipe body, stiffener and bulkhead. The stiffener is placed in the hollow cavity of the hollow pipe body; two ends of said hollow pipe body are closed by bulkheads. In the interior of at least one of hollow pipe body, stiffener and bulkhead a reinforcer is contained. It is characterized by that at least one laminated layer is set in the interior of hollow pipe body or stiffener or bulkhead, said laminated layer is set on the pipe wall of combined position of hollow pipe body and bulkhead. Said thin-wall pipe is applicable to various cast-in-situ concrete floor, roof, wall body, foundation baseplate and buildings of road and bridge engineering. Specially, it is applicable to hollow beamless floor.

Description

[0001] This application is a divisional application of an invention patent application with an application date of October 21, 2003, an application number of 200310101170.0, and a title of “a thin-walled pipe for concrete filling”. (1) Technical field [0002] The invention relates to a thin-walled pipe for concrete filling. (2) Background technology [0003] At present, in the existing technology, the hole-forming components of cast-in-place hollow slabs are permanent mandrels, such as paper tubes, plastic tubes, metal bellows, and lightweight materials for mandrels. Small floor weight. For example, the patent No. 99249755.8 is a fiber-reinforced thin-walled tube for filling cast-in-place reinforced concrete. It consists of a hard thin-walled tube and plugs at both ends. The two plugs seal the two ends of the hard thin-walled tube to form a closed cavity. , The cross section of the hard thin-walled tube and the shape of the plug can be round, square, trapezoidal or other s...
