Abstract

The utility model provides an FRP sectional steel sea-sand concrete component comprising sea-sand concrete, FRP sectional steel contained in the sea-sand concrete, and FRP ribs arranged outside the sea-sand concrete. The FRP sectional steel sea-sand concrete component has the benefits that the sea sands do not need to be processed by the sea-sand concrete component, and the sea-sand concrete are used directly to replace the traditional reinforcement/steel pipe concrete structures.

Description

FRP shaped steel sea-sand concrete member

Technical field

The utility model relates to building concrete member, particularly a kind of FRP shaped steel sea-sand concrete member.

Background technology

Along with the develop rapidly of large-scale economic construction and building trade, at present, building sand is shortage day by day, and especially river sand shortage phenomenon appears in some coastal economy developed regions.China is vast in territory, and seeking upcountry and getting the sand source is one of approach, but freight charges are high and the infringement riverbed.Sea sand can be gathered materials on the spot, and cheap, but extra large sand includes sea salt, can cause heavy corrosion and cause building structure to destroy reinforcing bar in the concrete.

The utility model content

In order to solve existing technical problem, the utility model provides a kind of FRP shaped steel sea-sand concrete member, and it directly uses extra large sand, can substitute existing land sand or river sand reinforcing bar/encased structures.

The utility model solves existing technical problem, and a kind of FRP shaped steel sea-sand concrete member is provided, and this FRP shaped steel sea-sand concrete member comprises FRP shaped steel and the peripheral FRP muscle shaped steel in marine sand concrete, the marine sand concrete.

The transverse shape of FRP shaped steel described in the utility model is cross, H shape, C shape or clavate, or described FRP shaped steel is pipe or square tube.Described FRP muscle comprises FRP stirrup and the structure muscle that circumferentially is provided with along described marine sand concrete.

This sea-sand concrete member comprises the hollow region in described pipe or the described square tube.

This sea-sand concrete member comprises two relative C shape FRP shaped steel.

This sea-sand concrete member comprises at least one clavate FRP shaped steel.

Shaped steel is compared to prior art, and the beneficial effects of the utility model are: this sea-sand concrete member does not need extra large sand is handled, and directly uses to substitute traditional reinforcing bar/encased structures.

The specific embodiment

Below in conjunction with the description of drawings and the specific embodiment the utility model is further specified.

As Fig. 1 to shown in Figure 7, a kind of FRP shaped steel marine sand concrete post member, it comprises the FRP shaped steel 11 in marine sand concrete 12, the marine sand concrete 12 and the FRP muscle (this FRP muscle comprises FRP longitudinal structure muscle 13 and FRP stirrup 14) of marine sand concrete 12 peripheries.This marine sand concrete 12 directly selects for use extra large sand as fines, need not to carry out preliminary treatment such as fresh water desalination, interpolation corrosion inhibiter, help being extensive use of of extra large sand, help the building construction of extra large sand repository, on the whole, alleviate the exploitation pressure of land sand, river sand resource greatly, solved the expensive problem that land sand, the long-range exploitation transportation of river sand cause, so directly utilize extra large sand promptly to have economic benefit, help ecological, environmental protective again.

This sea-sand concrete member can be real cored structure or hollow core structures, and when being hollow core structures, this member also comprises the hollow region in described pipe or the described square tube.

The transverse shape of the described FRP shaped steel 11 of this member is cross, H shape, C shape or clavate, respectively as shown in Figures 1 to 4.In Fig. 1, the cross section of FRP shaped steel 11 is cross, at four free ends of this right-angled intersection the reinforcing rib that hangs down mutually is set respectively, to improve intensity.In Fig. 2, the cross section of FRP shaped steel is a H shape.In Fig. 3, the cross section of FRP shaped steel be two over against C shape, and the bent angle of C shape is the right angle.In Fig. 4, FRP shaped steel is clavate, along the bearing of trend setting of marine sand concrete.Or described FRP section bar is pipe or square tube, as shown in Figure 5, as shown in Figure 6, adopts pipe or square tube during square tube during pipe, and this moment, this sea-sand concrete member can be hollow-core construction on the whole, also can be solid construction.Generally speaking, FRP shaped steel preferably is arranged on the center of marine sand concrete, also can be positioned near the position, centre of marine sand concrete.As shown in Figure 7, be a kind of marine sand concrete girder construction.

Simultaneously, in order to guarantee the intensity of this sea-sand concrete member, this FRP muscle comprises that the vertical muscle 13 of FRP is or/and FRP stirrup 14.The vertical muscle 13 of FRP is provided with along described marine sand concrete bearing of trend, and FRP stirrup 14 circumferentially is provided with along described marine sand concrete.Particularly, when the cross section of marine sand concrete when being square, the vertical muscle 13 of FRP is preferably placed at square position, angle, and the vertical muscle 13 of FRP be many, and a FRP indulges muscle corresponding to one jiao of position.

The utility model adopts prefabricate FRP shaped steel, cast marine sand concrete outside it, and this structure can prevent FRP shaped steel unstability, can improve concrete compressive property again, more can resist the erosion of chlorion in the marine sand concrete.Simultaneously, FRP shaped steel can reduce the mechanics loss of member under fire at inside concrete.In addition, use the FRP bar to replace traditional reinforcing bar to be applied in the marine sand concrete, to strengthen the decay resistance of structure.Steel concrete is the form of structure that is most widely used at present, solve the effective method of corrosion of steel bar problem and promptly be to use the fiber reinforced material muscle to replace reinforcing bar, so FRP muscle marine sand concrete has wide development space.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
