Technical field
The utility model relates to building and civil engineering structures reinforcing technique field, and a kind of specifically load bearing wall adds solid.
Background technology
Masonry structure is a kind of architecture structure form with long history of China, and at present, many buildings that China continues to use still belong to masonry structure.But masonry structure resistance to compression, tension, shear strength are low, poor seismic behavior, and problems such as member cracking, bearing capacity deficiency can appear in long-term use.In addition, the storey-adding reconstruction of masonry structure or function of use change etc. all can cause the bearing capacity of original structure not enough, need reinforce the bearing capacity that improves structure to supporting member.
At present, allowable ratio of height to sectional thickness of masonry wall or column reinforcement means commonly used is mesh reinforced cement mortar reinforcing method and outer sticking fiber-reinforced polymer (Fiber Reinforced polymer is called for short FRP) reinforcing method.For mesh reinforced cement mortar reinforcing method, construction technology is simple, and applicability is strong, and masonry is reinforced the back bearing capacity and improved a lot.But the masonry structure globality is poor, and a little less than the ability of resistance to deformation, the raising of masonry bearing capacity is reinforced in restriction to a certain extent; For outer sticking fiber-reinforced polymer FRP reinforcing method, can improve the globality of allowable ratio of height to sectional thickness of masonry wall or column, the reinforcement deformability; But the capacity under axial effect to allowable ratio of height to sectional thickness of masonry wall or column is very little; Simultaneously, fiber-reinforced polymer FRP and masonry be connected a little less than, being prone to take place stripping damage influences consolidation effect.
The utility model content
The purpose of the utility model provides a kind of load bearing wall and adds solid; Utilize fiber-reinforced polymer FRP to strengthen the globality and the deformability of allowable ratio of height to sectional thickness of masonry wall or column, utilize expanded metal lath or steel mesh reinforcement to improve the bearing capacity of allowable ratio of height to sectional thickness of masonry wall or column simultaneously, it is simple to make every effort to reinforcement process; Easy to operate; Little to the physical dimension increase, do not influence production, economic benefit is high.
The utility model load bearing wall adds solid, comprises the rigidity stratum reticulare, and said rigidity stratum reticulare one side is provided with fiber-reinforced polymer layer 5.
The opposite side of said rigidity stratum reticulare is provided with rubble English layer of sand 9.
Said rubble English layer of sand 9 outsides also are provided with antirust, decorative layer 10.
Said rigidity stratum reticulare is steel plate stratum reticulare 6 or reinforcing bar stratum reticulare 7.
Said fiber-reinforced polymer is carbon fiber reinforced polymer, glass fiber reinforced polymer, aramid fiber enhancing polymer or basalt fiber-reinforced polymer.
The place, reinforcing bar crosspoint of said reinforcing bar stratum reticulare 7 is provided with screw rod.
The advantage that the utility model load bearing wall adds solid is:
1, the utility model is applicable to the reinforcing to the ordinary masonry load bearing wall; The advantage of reinforcing fiber-reinforced polymer FRP reinforcing and expanded metal lath, steel mesh reinforcement organically combines; Not only improve the overall performance and the anti-ability of collapsing of allowable ratio of height to sectional thickness of masonry wall or column, and increase masonry rigidity, improve masonry capacity under axial and shear-carrying capacity; Improve the masonry anti-seismic performance, consolidation effect is good;
2, in the utility model; Expanded metal lath or steel mesh reinforcement can improve greatly between fiber-reinforced polymer FRP and the masonry and be connected more weak shortcoming; Guarantee fiber-reinforced polymer FRP in loading process with masonry compatibility of deformation, stressed jointly, prevent to occur peeling off between fiber-reinforced polymer FRP and the masonry;
3, not only consolidation effect is good for the utility model, and reliability is high, and simple to operate; Easy construction does not need special construction equipment, increases less to the masonry size; Do not influence production, economic benefit is high, is specially adapted to the masonry structure load bearing wall is keeped in repair on a large scale, reinforces.
