Abstract
Disclosed is a hollow pipe used in cast-in-place concrete, comprising a cylinder (1) and sealing plugs (2). The cylinder (1) is sealed by the sealing plugs (2) on the two ends of the cylinder (1), which forms the hollow pipe. The utility model is characterized in that the sealing plug (2) on at least one end is provided with an interfacing apparatus (3) for connecting and positioning the hollow pipes. In this way, when the hollow pipes are applied in layouting the cast-in-place concrete hollow floor, as the interfacing apparatuses for positioning the pipes are connected among the pipes, the pipes are convenient to be connected and do not displace or dislocate. Thus, the construction is easy, and the results do not occur that the widths of secondary ribs of the cast-in-place concrete do not accord with each other and the thicknesses of protection layers of the concrete outside the pipe do not accord with each other, thereby assuring the overall quality of the cast-in-place concrete hollow floor, meeting the requirements of mechanical behavior of the floor and reducing the construction cost. At the same time, the utility model has characteristics of simple structure, easy production, low cost and high strength.
Description
(1) technical field
The utility model relates to hollow section for in-site pouring concrete.
(2) prior art
At present, in the prior art, it is permanent core that cast-in-situ hollow floor plate becomes pole, and as paper tube, plastic pipe, metal bellows, core light material etc., these tubular core molds or member mainly consider to find time concrete, reduce floor weight.It as the patent No. 99232921.3 cast-in-place reinforced concrete filling 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, and the cross section of horniness thin-walled tube and plug shape can be circle, square, trapezoidal or other is special-shaped.When it is applied to cast-in-situ concrete hollow floor and lays; be easy to generate displacement or dislocation between the body each other; lay inconvenient; be prone to phenomenons such as Cast-in-place concrete time rib width between the tube and tube is inconsistent, the outer concrete cover variable thickness of pipe causes; thereby influence the total quality and the stress performance of cast-in-situ concrete hollow floor; increase difficulty of construction, therefore, develop a kind of novel hollow section for in-site pouring concrete for being badly in need of.
(3) summary of the invention
The purpose of this utility model is to provide a kind of hollow section for in-site pouring concrete, when being applied to cast-in-situ concrete hollow floor, have body lay convenient, do not produce characteristics such as displacement or dislocation, construction are easy.
Solution of the present utility model is the docking facilities that plug is provided with connection location between the hollow section that seals at least one end of hollow section.Like this; when hollow section is applied to the cast-in-situ concrete hollow floor laying; owing to the docking facilities that connects the location is arranged between the tube and tube, thereby the body laying is easy to connect, can produce displacement or dislocation each other; construction easily; phenomenons such as Cast-in-place concrete time rib width between the tube and tube is inconsistent, the outer concrete cover variable thickness of pipe causes can not occur, guarantee the total quality of cast-in-situ concrete hollow floor, satisfy the requirement of superstructure stress performance; reduce construction cost, thereby reached the purpose of this utility model.Simultaneously, hollow section for in-site pouring concrete also has structure tube list, produces easy, characteristics such as cost is low, intensity height.
The docking facilities that feature of the present utility model also is between the hollow section to connect the location is to seal the butt hole that is provided with on the plug, hole or be connected latch or be both combination simultaneously with butt hole, hole are corresponding.Like this, can couple together easily by connecting latch between the hollow section, construction easily.
Feature of the present utility model is that also the docking facilities that connects the location between the hollow section is fixing or movable hoop.Like this, insert hoop by pipe end between the hollow section, perhaps can couple together easily each other in the hoop insertion tube, and construction is simple.
