Abstract
The utility model relates to an oblique fibre cloth diamond structure for reinforcing building block and raising shear resistance; the fibre cloth is pasted at the surface of the building block; the fibre cloth comprises more than four fibre cloth that is obliquely crossed and dispersedly arranged, and a diamond structure is formed; the surface of the building block is pasted with the fibre cloth, and is fixed by a rivet. A plurality of fibre cloth which are dispersed, skew crossing, rhombic are pasted at the surface of the building block of the utility model; the shear resistance of the building block is raised through riveting action; through the adoption of the structure, a staggered mesh is formed by a plurality of oblique fibre cloth, and is corresponding to the principal stress direction of the building block under the function of the horizontal force; the stress of the building block is even; the effective restraint area to the building block is increased, which is in favor of sustaining the integrality of the building block, enhancing the shear resistant ability of the building block and increasing the ductility of the building block; and thus the reinforcing effect of the building block is obvious. The construction of the utility model is fast, the period is shortened, and the weight of the original structure is scarcely increased.
Description
Technical field
The utility model relates to masonry shearing resistance bracing means, and particularly a kind of masonry shearing resistance is reinforced with inclined type cloth diamond structure.
Background technology
In horizontal shear is under the effect of seismic forces, and masonry tends to occur the diagonal member crack, and along with load increases, the crack increases gradually, finally causes masonry to be damaged and loses supporting capacity.In order to improve the masonry shear resistance is antiseismic effect, need reinforce masonry.
Traditional reinforcement measure is to lay gauze wire cloth on masonry surface, brushes one deck mortar then, and gauze wire cloth by connector and former masonry drawknot together.The shortcoming of this kind reinforcing mode is that construction period is longer, and has increased the deadweight of original structure.
Fibre reinforced composites at the beginning of the nineties at the end of the eighties (Fiber Reinforced Plastics is called for short FRP) enter the civil engineering field of reinforcement, and the fibre reinforced composites so that sheet-form occurs are commonly called cloth (FRP sheet).The FRP properties of materials is light weight, intensity height.The FRP reinforcing technique is by bonding adhesive the FRP material to be sticked on the surface at member stress position, to improve bearing of component.
In reinforcing, the masonry shearing resistance often adopts FRP reinforcing mode as depicted in figs. 1 and 2 at present.Diagonal member fork shown in Figure 1 is pasted the breakoff phenomenon that occurs usually at the masonry shearing resistance and is designed, this kind bonding method makes cloth less to the operative constraint area of masonry, although the cloth of intersection bias laid is effective to appearance and the development of controlling main diagonal crack on the diagonal, but reinforce the back oblique fork cloth constraint less than the place some cracks parallel with diagonal have appearred again, this kind phenomenon shows, only pastes the shear resistance that cloth can not be improved whole masonry effectively at the diagonal member fork.
Masonry shearing resistance reinforcing mode shown in Figure 2 designs with reference to the paving mode of reinforcing bar in the reinforced masonry.Under the horizontal shear effect, the principal tensile stress direction in the masonry is oblique, and obvious horizontal band cloth is not to be in best stressed position.Reinforcing bar can only level be embedded in the mortar joint, but cloth can be pasted by any direction.Therefore, in order more effectively to bring into play the effect of cloth, need determine the stickup direction of cloth according to the concrete condition of masonry.
Summary of the invention
Task of the present utility model provides a kind of improved masonry shearing resistance and reinforces with inclined type cloth diamond structure, and it has solved diagonal member fork of the prior art and has pasted shear resistance and the masonry that cloth can not effectively improve whole masonry and post the problem that horizontal band cloth can not be in best stressed position.
The technical solution of the utility model is as follows:
A kind of masonry shearing resistance is reinforced with inclined type cloth diamond structure, and cloth adheres on the masonry surface, and described cloth is made up of the cloth of four above diagonal cross dispersed placement, and constitutes diamond structure, and it is surperficial and by the rivet rivet clasp that cloth sticks on masonry.
It is the cloth that posts dispersion, many, diagonal cross on the masonry surface and assume diamond in shape that masonry shearing resistance of the present utility model is reinforced with inclined type cloth diamond structure, masonry is carried out the shearing resistance reinforcing, and take the rivet clasp measure.
Adopt cloth diamond structure of the present utility model, several inclined type cloth form the intersection grid, corresponding with the principal direction of stress in the masonry under the horizontal force action, make masonry stressed more even, operative constraint area to masonry increases, and helps keeping the globality of masonry, improves the shear resistance of masonry, increase the ductility of masonry, thereby make that the masonry consolidation effect is more obvious.
The utility model construction is convenient, and the cycle shortens, and increases the weight of original structure hardly.
Description of drawings
Fig. 1 is the schematic diagram that diagonal member fork cloth of the prior art adheres on the masonry surface.
Fig. 2 is the schematic diagram that horizontal band cloth of the prior art adheres on the masonry surface.
Fig. 3 is that the schematic diagram that adheres on the masonry surface with inclined type cloth diamond structure is reinforced in a kind of masonry shearing resistance of the present utility model.
The specific embodiment
Referring to Fig. 3, the utility model is that a kind of masonry shearing resistance is reinforced with inclined type cloth diamond structure, has posted cloth 2 on masonry 1 surface.Cloth 2 is made up of the cloth of several diagonal cross, dispersed placement, and constitutes several diamond structures.
Cloth 2 sticks on masonry surface 1, and by rivet rivet clasp in addition.
Paste the cloth of several diagonal cross on the masonry surface and reinforce masonry is carried out shearing resistance, for example affixing carbon fabric can improve shear strength of masonry 55%, and displacement improves 60%; Sticking glass fabric can improve shear strength of masonry 33%, and displacement improves 62%.When pasting the glass fabric of arranging same amount, disperse to paste layout than only concentrating on diagonal and pasting and can improve intensity 10%, displacement improves then more.
The utility model is applicable to the shearing resistance reinforcing of the masonry of being made by materials such as solid brick, hollow brick, concrete blocks, and pasting the cloth of arranging can be fibre reinforced composites such as carbon cloth, glass fabric, aryl fiber cloth.
