Abstract

The utility model relates to a fiber reinforced plastic (FRP) and concrete composite board, which comprises an FRP open-web board, wherein a plurality of reverse-T-shaped perforated FRP connecting elements are pasted on the FRP open-web board, FRP perforation distributing ribs penetrate through holes of the FRP connecting elements, FRP board surface distributing ribs are arranged above the FRP perforation distributing ribs, the FRP open-web board, the FRP connecting elements, the FRP perforation distributing ribs and the FRP board surface distributing ribs form an open-web board support frame, and concrete is cast on the open-web board support frame. The open-web board support frame provided by the utility model has light dead weight, high carrying capability and a good corrosion resistance performance, has the characteristic of simple structure and is convenient to use.

Description

FRP and concrete combined board

Technical field

The utility model belongs to field of civil engineering, relates to building unit, relates in particular to a kind of FRP and concrete combined board.

Background technology

In civil engineering, hollow FRP-concrete combined board is a kind of novel compoboard.Hollow FRP-concrete combined board is meant direct concreting on the FRP hollow slab, makes the two in conjunction with closely forming cooperative floor or bridge deck by various combination connecting modes then.Compare remarkable advantage such as the FRP material has high-strength light, corrosion resistance is strong and anti-fatigue performance is good with traditional structural materials.The FRP-concrete combined board does not need formwork and sets up interim support in construction works, it is very convenient to construct.FRP-concrete combined bridge deck through design rationally is subjected to the attention of engineering circle gradually, at home and abroad uses more and more widely in the field of civil engineering.

Present FRP-concrete combined board, it is bigger to conduct oneself with dignity, and supporting capacity is relatively poor relatively.

Summary of the invention

In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of FRP and concrete combined board, and its deadweight is less, and supporting capacity is strong, and corrosion resistance and good has characteristics simple in structure, easy to use.

In order to achieve the above object, the technical solution adopted in the utility model is:

FRP and concrete combined board, comprise FRP hollow slab 1, be pasted with at least two inverted T shape perforate FRP connectors 2 on the FRP hollow slab 1, be penetrated with FRP perforation distributions muscle 3 in the hole of FRP connector 2, FRP plate face distribution bar 4 is set above FRP perforation distributions muscle 3, described FRP hollow slab 1, FRP connector 2, FRP perforation distributions muscle 3 and FRP plate face distribution bar 4 are formed the hollow slab support, have built concrete 5 on described hollow slab support.

Described FRP connector 2 is a plurality of.

Described FRP perforation distributions muscle 3 is a plurality of.

Described FRP plate face distribution bar 4 is intersected by vertical FRP plate face distribution bar and horizontal FRP plate face distribution bar to be formed.

Described vertical FRP plate face distribution bar and horizontal FRP plate face distribution bar all are a plurality of.

Described vertical FRP plate face distribution bar and horizontal FRP plate face distribution bar equidistantly distribute.

The utility model compared with prior art has the following advantages:

1) each member can prefabricatedly be finished, and the scene is used in combination, and both can ensure the quality of products, again reduction of erection time greatly.

2) with respect to traditional reinforcing bar and steel, it is lighter to conduct oneself with dignity, and plate is thick more, and deadweight reduction amplitude is big more.

3) corrosion resistance and good, good endurance.

4) has good anti-fatigue performance.

5) the FRP hollow slab can play the permanent template effect in the bridge deck work progress, exempts the template dismounting and sets up work with interim the support, very easily realizes rapid construction and safe construction.

6) can be designed to Orthogonal Double to same sex plate, more effectively improve supporting capacity.

7) has better shock resistance weight bearing power.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is a transverse sectional view of the present utility model.

Fig. 3 is a side sectional view of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further details.

Shown in Figure 2 as Fig. 1, the utility model is FRP and concrete combined board, comprise FRP hollow slab 1, be pasted with at least two inverted T shape perforate FRP connectors 2 on the FRP hollow slab 1, be penetrated with FRP perforation distributions muscle 3 in the hole of FRP connector 2, FRP plate face distribution bar 4 is set above FRP perforation distributions muscle 3, and described FRP hollow slab 1, FRP connector 2, FRP perforation distributions muscle 3 and FRP plate face distribution bar 4 are formed the hollow slab support, have built concrete 5 on described hollow slab support.

For the FRP hollow slab 1 of better arranging in pairs or groups, the quantity of FRP connector 2 and FRP perforation distributions muscle 3 all is plural number.

In order to obtain better effect, FRP plate face distribution bar 4 is made up of vertical FRP plate face distribution bar and horizontal FRP plate face distribution bar quadrature intersection, and vertically the quantity of FRP plate face distribution bar and horizontal FRP plate face distribution bar also all is that plural and vertical FRP plate face distribution bar and horizontal FRP plate face distribution bar equidistantly distribute.

The FRP section bar is compared traditional steel and reinforcing bar, can play the advantageous effect that reduces dead load in engineering structures, and is especially obvious for span bigger bridge deck and floor application advantage.Adopt the utility model compoboard of FRP hollow slab, it is very light to conduct oneself with dignity, and the ordinary reinforced concrete solid slab conduct oneself with dignity and reduce greatly, and plate is thick more relatively, and deadweight reduction amplitude is big more; Simultaneously, the FRP specific strength be steel 20-50 doubly, substitute traditional steel and reinforcing bar and can reduce the bridge construction deadweight, thereby effectively alleviate the bridge construction geological process, more can reduce the bridge design load significantly, thereby can bigger increase bridge limit span; FRP section bar decay resistance is fine, adopts FRP principal rod and distribution bar simultaneously in the combined bridge deck board concrete, can greatly improve and effectively solve the crucial difficult problem of durability of reinforced concrete bridge deck plate; The FRP material has the good fatigue resistance energy in combined bridge deck, and the while concrete mainly is positioned at pressure zone and seldom ftractures, and can not cause the Cumulative Fatigue Damage fast development, and therefore, combined bridge deck has the good fatigue resistance energy; The FRP hollow slab can play the permanent template effect in the bridge deck work progress, exempt the template dismounting and set up work with interim the support, very easily realizes rapid construction and safe construction.

The most of manufacturing process of compoboard of the present utility model can be prefabricated in the factory and finish, therefore, promptly can fine assurance fabricating quality, can shorten the construction period greatly again, have significant advantage, especially the repairing maintenance works for bridge has remarkable meaning more; Because from heavy and light, rigidity is big, intensity is high, this compoboard has quite big application prospect in engineerings such as long-span bridge panel, large bay floor, basement roof.Under the appropriate design prerequisite, compoboard of the present utility model can be designed to Orthogonal Double to same sex plate, more effectively improves supporting capacity.
