Abstract
The present invention relates to a thin-walled cylinder member for the filling of cast-in-situ reinforced concrete, which comprises a hard thin-walled pipe (1) and plugs (2). The plugs (2) close both ends of the hard thin-walled pipe (1) to form a closed cavity (3). The present invention is characterized in that the thin-walled cylinder member also comprises a bottom slab (4) and a connecting piece (5). At least one hard thin-walled pipe (1) is connected with the bottom slab (4) into a whole through the connecting piece (5). The hard thin-walled pipe (1), the connecting piece (5) and the bottom slab (4) form the integral member. Blocks made of lightweight materials are arranged in the closed cavity and are arranged on the bottom slab (4) at intervals. As a result, the present invention is suitable for cast-in-situ reinforced concrete hollow structures, particularly suitable for being used in hollow storied building roofs, house roofs, base slabs, wall bodies and hollow bridges.
Description
The application for the applying date be that March 11, application number in 2003 are 200610008749.6, name is called the dividing an application of application for a patent for invention of " a kind of structural member with thin-wall cylinder for filling cast-in-situs reinforcing bar concrete light-wall pipe ".
(1) technical field
The present invention relates to a kind of thin-wall barrel member for cast-in-place reinforced concrete filling.
(2) background technology
At present, in the prior art, it is permanent core that cast-in-situ hollow floor plate becomes pole, as paper tube, plastic pipe, metal bellows, core light material etc.These tubular core molds or member are mainly considered the concrete of finding time, and alleviate floor weight.As the patent No. by applicant's application is that ZL99249775.8, name are called the utility model patent of " cast-in-place reinforced concrete filling fiber reinforcement type thin wall cylinder ", it is made up of horniness thin-walled tube and two ends plug, two plugs form an enclosed cavity with the horniness thin-walled tube closed at both ends, this hard thin-wall tube wall is composited by carcass and cementitious materials, carcass can be glass fiber or carbon fiber or organic fiber or nonwoven or fibrous braid, and cementitious materials can be cement or organic resin or is the mixture of cement, filler, Admixture, fiber.This kind pipe has advantages such as intensity height, resistance to deformation, anti-vibration performance are good, convenient construction and transport.But along with the progress of construction technology, in the past, individual tubes is laid by root has influenced construction speed, and relative fixed each other and location seem and too bother.Therefore, develop a kind of novel thin-wall barrel member for cast-in-place reinforced concrete filling for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of thin-wall barrel member for cast-in-place reinforced concrete filling, be applied in hollow-core construction building (room) lid, have characteristics such as speed of application is fast, convenient and simple, also have the intensity height simultaneously, from characteristics such as heavy and light, resistance to deformation, anti-seismic performance be good.
Solution of the present invention is on the basis of existing technology, comprise horniness thin-walled tube, plug, plug forms an enclosed cavity with the horniness thin-walled tube closed at both ends, it is characterized in that also including base plate, connector, at least one horniness thin-walled tube connects to integral body by connector and base plate, horniness thin-walled tube and connector and base plate constitute integrated member, fill in the cavity of horniness thin-walled tube and use light material.Like this, when floor construction, directly be placed in thin-wall tube member on the bracing frame, its base plate is equivalent to template, and light-wall pipe is relative positioning and fixing, thereby floor construction speed is fast, convenient and simple, simultaneously, the hard thin-wall pipe component also has characteristics such as intensity height,, convenient transportation good from heavy and light, resistance to deformation, anti-seismic performance, is applicable to the cast-in-situ reinforced concrete hollow structure, is particularly useful for hollow building cover, roof system, sole plate, body of wall and hollow bridges and uses.
Feature of the present invention is that also described connector is rib or support or reinforcing bar or punch.Like this, connector wide in variety makes things convenient for the design and the production of thin-wall tube member, helps reducing producing and construction cost.
Feature of the present invention also is have arm to link mutually between the described many horniness thin-walled tubes.Like this, owing to have arm to link mutually between the light-wall pipe, its globality is better, and simultaneously, the concrete in the superstructure is further emptied, thus the concrete consumption of superstructure is little, good from heavy and light, anti-seismic performance, and the vertical cross stiffness difference of superstructure reduces, mechanical property is greatly improved.
