Description

A kind of close rib truss bars insulation box-type member of precast concrete
Technical field
The utility model is related to a kind of close rib truss bars insulation box-type member of precast concrete, belongs to architectural engineering neck Domain.
Background technology
The conventional precast concrete box-type member of Building Trade in China is larger in the presence of deadweight at present, it is difficult to which that transports and lift lacks Point, and when being made at temporary home of precast concrete box-type member, have the shortcomings that energy-saving effect is poor;And in general band, The precast concrete box-type member of external thermal insulation or sandwich heat preservation, there is also problems with:1. the box-type member of outer patch insulation material, Its insulation material durability is bad, easily comes off, and 2. the box-type member of interior patch insulation material can directly affect the headroom chi of casing It is very little, 3. using similar " sandwich " structure sandwich heat preservation box-type member, it is thicker often to there is concrete wall thickness, or stress Poor performance, it is easy to crack the shortcomings of.
Utility model content
The utility model in order to overcome drawbacks described above, its object is to provide a kind of lightweight, heat insulation effect stabilization persistently and The close rib truss bars insulation box-type member of precast concrete of structure stress clear and definite, can effectively reduce member dead weight, maximum Change empty size in expansion cabinet, and heat preservation and energy conservation effects are excellent.Multiple this kind of box-type member unit spliceds can use construction together Underground pipe gallery, interim or semipermanent residence.
The utility model to achieve these goals, is adopted the following technical scheme that:
A kind of close rib truss bars insulation box-type member of precast concrete, it includes the concrete slab that four skirts are closed, and Box-structure is enclosed, the internal structure of concrete slab is the close rib shape concrete with truss bars I, truss bars II;
Close rib shape concrete and thin-walled slab concrete one similar framed bent of formation of upper and lower two-layer steel wire plain net Cellular structure;
The truss bars I of close rib shape inside concrete, truss bars II are on the corner effectively overlapped;Enhancing is overall Property.
In the close rib shape concrete, the bar shaped inside concrete at box-type member corner edge sets some vertical reinforcements And stirrup;
In the close rib shape concrete, the bar shaped inside concrete at box-type member hole edge sets a plurality of truss bars II, mainly play frame column.
Further, the cavity between the levels of thin-walled slab concrete is filled out using the construction material with heat insulation function Fill.
Truss bars in the close rib shape concrete is the steel bar stress of structure, carries class in building frame construction Like the effect of framework beam steel, single truss bars or multiple purlins can be adjusted to according to the change of scantling and stress morphology Frame reinforcing bar.
The close rib shape concrete with truss bars combines to form a class with the slab concrete of steel wire plain net Like the contignation system of bent structure, such stress Path of Force Transfer clear and definite greatly reduces concrete and rebar Consumption.
Chamber portion in the cellular structure can be carried out with the construction material of the organic or inorganic with heat insulation function Filling, it is also possible to which what is not filled out, keeps cavity, and the shape of cavity both can be a rectangle, or square, circle Shape, ellipse or be arbitrary polygon.
Planar steel wire screen in the tabular thin wall concrete of the steel wire plain net is the steel bar stress of thin wall concrete and is resisted Reinforcing bar is split, prevents concrete plate surface from crack occur, planar steel wire screen can join according to scantling and stress morphology come adjustment technology Number, can be adjusted to the reinforcing bar combining form of the bending resistances such as reinforcing bar plain net, steel wire net rack and bar frame design.
The planar steel wire screen and truss bars should be connected effectively, can weld together can also colligation together.
The concrete of the box-type member, its concrete material can be various concrete, such as normal concrete, high-strength Concrete, self-compacting concrete, foam concrete etc..
The beneficial effects of the utility model:
The utility model can allow conventional concrete box component on the premise of drag performance is not influenceed, weight reduction one More than half;
The utility model reduces disaster hidden-trouble;
The utility model reduces the consumption of concrete and reinforcing bar;
The utility model causes the specific heat preservation energy-saving function of concrete box component, has expanded box component in building field Range of application.
The utility model realizes factorial praluction, convenient and swift, greatly shortens the time of architecture construction.

Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings:
A kind of close rib truss bars insulation box-type member of precast concrete, it includes the concrete slab that four skirts are closed, and Box-structure is enclosed, the internal structure of concrete slab is that the close rib shape with truss bars I 1.1, truss bars II 1.2 is mixed Solidifying soil 2;
Close rib shape concrete 2 forms a similar framed bent with the thin-walled slab concrete 4 of upper and lower two-layer steel wire plain net 3 Cellular structure(Fig. 7);
Truss bars I 1.1, truss bars II 1.2 inside close rib shape concrete 2 are on the corner effectively overlapped, Enhancing globality.
In the close rib shape concrete 2, some vertical steels are set inside the bar shaped concrete 6 at box-type member corner edge Muscle 7 and stirrup 8, mainly play framework beam effect.
In the close rib shape concrete 2, a plurality of Truss Steel is set inside the bar shaped concrete 9 at box-type member hole edge Muscle II 1.2.
Cavity between the levels of thin-walled slab concrete 4 is filled using the construction material 5 with heat insulation function.
