The present invention is characterized in that a base plate (5) and a connecting piece (6) are arranged below the rigid thin-wall pipes (2); at least one rigid thin-wall pipe (2) is connected with the base plate (5) into a whole through the connecting piece (6); the base plate (5) is parallel to the bottom surface of the cast-in-situ reinforced concrete hollow slab and is formed into a whole with the cast-in-situ reinforced concrete (1). Therefore, the present invention overcomes that defects single pipes are laid root by root during the construction of the past cast-in-situ reinforced concrete hollow slab, construction progress is slow, mutually corresponding fixing and positioning are too complicated, etc. The present invention has the characteristics of fast construction progress, convenience, simplicity, etc. and is suitable for various structures of cast-in-situ concrete floor cover, roof, foundation bottom plate, road and bridge engineering.
Description
(1) technical field
The present invention relates to a kind of cast-in-situ reinforcing steel bar concrete hollow slab.
(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.This kind light-wall pipe is wrapped up in and is contained in the steel bar concrete, be vertically arranged with the cast-in-situ reinforced concrete longitudinal rib each other, can form cast-in-situ reinforcing steel bar concrete hollow slab, but progress along with construction technology, past, during the hollowcore slab construction, 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 cast-in-situ reinforcing steel bar concrete hollow slab for being badly in need of.
(3) summary of the invention
The object of the present invention is to provide a kind of cast-in-situ reinforcing steel bar concrete hollow slab, have characteristics such as speed of application is fast, convenient and simple.
Solution of the present invention is on the basis of existing technology, include steel bar concrete, horniness thin-walled tube, the two ends of horniness thin-walled tube are provided with plug it are sealed, horniness thin-walled tube is wrapped up in and is contained in the steel bar concrete, be vertically arranged with the cast-in-situ reinforced concrete longitudinal rib between the horniness thin-walled tube, it is characterized in that also being provided with under the horniness thin-walled tube base plate, connector, at least one horniness thin-walled tube connects to integral body by connector and base plate, base plate flushes with the cast-in-situ reinforcing steel bar concrete hollow slab bottom surface, and forms integral body with cast-in-situ reinforced concrete.Like this, owing to also be provided with base plate, connector under the horniness thin-walled tube, at least one horniness thin-walled tube connects to integral body by connector and base plate, and base plate flushes with the cast-in-situ reinforcing steel bar concrete hollow slab bottom surface, and forms integral body with cast-in-situ reinforced concrete, thereby overcome when cast-in-situ reinforcing steel bar concrete hollow slab is constructed in the past, individual tubes is laid by root, and construction speed is slow, each other relative fixed and location deficiency such as trouble too, have characteristics such as speed of application is fast, convenient and simple, thereby reached purpose of the present invention; Simultaneously, that cast-in-situ reinforcing steel bar concrete hollow slab also has is simple in structure, intensity is high, in light weight, characteristics such as the shock stability that shakes is good, cost is low, be applicable to the structure of various Cast-in-place Concrete Building Floor, roof system, body of wall, sole plate and road and bridge engineering, be specially adapted to hollow arch without beam.
Feature of the present invention also is to be provided with rib between the cast-in-situ reinforced concrete end between the pipe end of described horniness thin-walled tube.Like this, the vertical cross stiffness difference of cast-in-situ reinforcing steel bar concrete hollow slab reduces relatively, and mechanical property improves greatly.
Feature of the present invention is that also rib is a rib between elongated end between described cast-in-situ reinforced concrete end.Like this, not only the vertical cross stiffness difference of cast-in-situ reinforcing steel bar concrete hollow slab further reduces, and mechanical property improves greatly, and it is simpler to construct, and speed of application is faster.
Feature of the present invention is also that rib and cast-in-situ reinforced concrete longitudinal rib are grid each other between the elongated end of described cast-in-situ reinforced concrete and arranges.Like this, rib and cast-in-situ reinforced concrete longitudinal rib are the grid layout each other between the elongated end of Cast-in-place concrete, formed netted force transferring structure in cast-in-situ reinforcing steel bar concrete hollow slab, thereby hollowcore slab have become the two-way slab of function admirable.
Feature of the present invention also is described base plate spaced set each other.Like this, base plate is spaced set each other, makes base plate and Cast-in-place concrete firmly be combined into integral body, and the base plate of hollowcore slab can not ftractureed.
Feature of the present invention is that also described base plate is each other continuously apart from being provided with.Like this, base plate continuously apart from being provided with, makes hollowcore slab not need soffit formwork in manufacturing process each other, greatly reduces the cost of manufacture of hollowcore slab.
Feature of the present invention also is the setting interlaced with each other of described base plate.Like this, interlaced with each other being provided with of base plate is beneficial to the bottom stress dispersion, also can not cause continuous destruction even run into the violent earthquake generation than large deformation.
The length that feature of the present invention also is described horniness thin-walled tube less than or be greater than or equal to the length of base plate.Like this, the length of horniness thin-walled tube less than or when being greater than or equal to the length of base plate, made things convenient for selecting for use of design and construction unit.
The diameter that feature of the present invention also is described horniness thin-walled tube less than or be greater than or equal to the width of base plate.Like this, made things convenient for selecting for use of design and construction unit.
