Description

A local reinforcement device for building structures

technical field

The invention relates to the overall stability of the building structure system, especially the strengthening measures for the connection between components in the structure or the rigidity of the components themselves.

Background technique

The construction industry has gone through three stages of development: the stage of large-scale new construction, the stage of equal emphasis on new construction and maintenance, and the stage of renovation, maintenance and reinforcement of old buildings; foreign countries have entered the stage of large-scale reinforcement and transformation since the 1960s, while my country It has only entered this stage since the 1990s.

The main purpose of building reinforcement is to improve the structural performance of the building, to deal with damage caused by insufficient connection strength between components when an earthquake occurs or the building itself is damaged, that is, to meet the reliability of the structure, and the focus is to improve its bearing capacity and guarantee The normal usability meets the use requirements in terms of structural safety and stability, and at the same time combines economical efficiency, energy saving, material saving, convenient construction and operation, and environmental protection.

The third reinforcement device includes a high-strength connection material, and the high-strength connection material fills the gap between the beam and the wall column in the rib-beam floor unit that needs to be reinforced.

The fourth reinforcement device adopts steel bars wrapped with carbon fiber cloth or sand-filled steel pipes or angle steels; the steel bars wrapped with carbon fiber cloths, sand-filled steel pipes or angle steels are pre-buried inside the walls to be reinforced.

The contact between the angle steel and the plate or wall column is bonded with high-strength water glass.

The high-strength connection material is repaired concrete or water glass.

The steel bars wrapped with carbon fiber cloth, sand-filled steel pipes and angle steels are arranged in a staggered manner such as cross braces or eight-character braces inside the wall.

The present invention has following beneficial effect:

1. By proposing four kinds of measures for the connection between the internal components of the building and the stability of the components themselves, it is possible to solve the problem of loose objects falling and partition walls falling when the building is subjected to earthquakes or other dynamic effects when the building is subjected to dynamic effects. Unstable and stable. To maintain the stability of the frame structure, or the relative stability of the whole, allowable small breakage occurs within the scope of repair.

2. It has the advantages of convenient construction, small engineering quantity, saving construction time and construction materials, and the effective component connection also has good mechanical performance under the condition that the structure is partially reinforced to ensure the safety and normal use of the building.

3. The building reinforcement measures proposed by the present invention can be used in brick-concrete structures as well, so as to increase the overall stability of the building structure; it can be used in civil buildings, industrial buildings, especially buildings with high seismic fortification requirements .

Detailed ways

Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

As shown in Figure 1-8, a local reinforcement device for building structures, which includes a first reinforcement device 1 for reinforcement between panels in floor units, panels and wall columns in floor units without beams The second reinforcement device 2 for reinforcement between them, the third reinforcement device 3 for reinforcement between the middle beam of the rib beam floor unit and the wall column, and the fourth reinforcement device 4 for reinforcement inside the wall itself.

Further, the first reinforcement device 1 includes a rigid connector 5, and the two ends of the rigid connector 5 are respectively inserted into the perforations of the prefabricated panels to be reinforced. The rigid connector 5 here can use prestressed steel bars, so as to improve the crack resistance, rigidity and impermeability of the components, fully exert the performance of the material, and save steel.

Further, the second reinforcing device 2 includes an angle steel 7, and the two sides of the angle steel 7 are respectively fixed by steel bars 8 between the plate and the wall column in the beamless floor unit to be reinforced.

Further, the third reinforcing device 3 includes a high-strength connecting material 9, and the high-strength connecting material 9 fills the gap between the beam and the wall column in the rib-beam floor unit that needs to be reinforced. It has good impermeability and weather resistance; cross-section beams can also be used between beams and slabs to ensure a better overall beam-slab structure.

Further, the fourth reinforcing device 4 adopts steel bars wrapped with carbon fiber cloth 6 or sand-filled steel pipes or angle steels 10; the steel bars wrapped with carbon fiber cloth 6, sand-filled steel pipes or angle steels 10 are embedded in the wall to be reinforced within itself.

Further, the contact between the angle steel 7 and the plate or wall column is bonded with high-strength water glass.

Further, the high-strength connecting material 9 is made of repairing concrete or water glass. High-strength water glass is used for bonding, and the silicic acid gel precipitated during hardening has strong adhesion and good bonding ability. Silicic acid gel can block the capillary pores of the material and form a continuous closed film on the surface, so it has good impermeability and weathering resistance.

Further, the steel bars wrapped with carbon fiber cloth 6 , sand-filled steel pipes and angle steels 10 are arranged in a staggered manner such as cross braces or eight-shaped braces inside the wall. For the steel plates or steel bars between the connecting plates, carbon fiber cloth 6 can be used to wrap and arrange in different ways, so that the elastic performance of the connecting parts can be fully exerted, with high strength, low density and thin thickness, and basically does not increase the self-weight of the reinforced member and section dimensions. Similarly, for the sand-filled steel pipe or angle steel 10 inside the wall, the carbon fiber cloth 6 can be used for winding reinforcement with the slit left.
