Abstract
The invention discloses a pre-stress angle steel plate reinforcing device, and belongs to the field of building structure seismic resistance reinforcing. The pre-stress angle steel plate reinforcing device mainly comprises four angle steel plates, connecting pieces and high-strength pre-stress bolts. The two ends of each angle steel plate are fixedly provided with the corresponding connecting pieces, and the high-strength bolts enable the two adjacent angle steel plates to be connected together through the connecting pieces to form the closed-loop reinforcing device, wherein the cross section of the closed-loop reinforcing device is matched with the cross section of a reinforced component. The pre-stress angle steel plate reinforcing device is clear in concept, capable of exerting large pre-stress on the reinforced component, convenient to construct and capable of being produced in a standardized mode easily and popularized and applied on a large scale in the broad earthquake defending regions easily.
Description
Technical field
The present invention relates to building structure aseismatic field of reinforcement, particularly a kind of prestressing force gusset bracing means.
Background technology
At present, the bracing means to pillar or beam often adopting has the technology such as outsourcing carbon cloth and encased steel plate, and these reinforcing techniques have all been applied in compared with in multiple-project.Although the reinforcing technique of outsourcing carbon cloth can improve ductility and the bearing capacity of member, but being the durability of the glue of affixing carbon fabric, its weak point is difficult to guarantee, can not effectively improve the rigidity of structural element, the structural element that pair cross-section is rectangle is simultaneously difficult to effectively apply prestressing force.The reinforcement means of encased steel plate can improve the bearing capacity and stiffness of member simultaneously, but weak point is to need Site Welding, construction inconvenience, and more difficult member is applied to prestressing force.
Therefore, develop a kind of strength and stiffness that can either improve structural element, can very effectively apply again prestressed anti-seismic strengthening device and just seem both urgent and meaningful especially.
Summary of the invention
In order to overcome being difficult to that current existing bracing means exists, effectively apply prestressing force and the inconvenient weak point of mostly constructing, the invention provides and a kind ofly can effectively apply prestressing force, and the prestressing force gusset bracing means of easy construction.
The technical solution adopted in the present invention is a kind of prestressing force gusset bracing means, it mainly comprises four gussets, connector and high-strength prestressed bolt, the two ends of every gusset are fixed wtih connector, and high-strength prestressed bolt is joined together to form a closed loop bracing means suitable with being reinforced member section by connector by two adjacent gussets.
Between described adjacent two gussets, with at least one above high-strength prestressed bolt, link together.
Described gusset is formed at end vertical welding by two rectangular steel plates together or by a rectangular steel plates bending.
Between described connector and gusset, must take to be connected reliably measure, guarantee effectively to transmit the pulling force of high-strength prestressed bolt.
The present invention has following remarkable advantage:
(1) can effectively apply larger prestressing force.Compare current existing most of encased steel plate bracing means, the present invention can apply transverse prestress to being reinforced member very effectively by high-strength prestressed bolt.
(2) easy construction.Most encased steel plate bracing means construction inconvenience, most of devices need Site Welding to install, and the present invention manufactures in factory, to on-the-spot, installs, and easy construction, without Site Welding operation.
(3) be easy to normalized production.Current most encased steel plate bracing means needs according to the cross-sectional sizes that is reinforced member prefabricated separately in factory, is difficult to normalized production, and the present invention can normalized production, is conducive to reduce the cost of bracing means.
The present invention can be used for reinforcing pillar, beam and bridge pier, not only can improve the bearing capacity, rigidity and the ductility that are reinforced member, and can effectively to being reinforced member, apply prestressing force, easy construction, be easy to normalized production, will be widely used in seismic hardening field.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the embodiment of the present invention.
Fig. 2 is that the present invention is arranged on the schematic diagram being reinforced on member.
In accompanying drawing, digital implication is as follows:
1-gusset; 2-connector; The high-strength prestressed bolt of 3-; 4-prestressing force gusset bracing means; 5-is reinforced member.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further detailed explanation.
As shown in Figure 1, the present invention is a kind of prestressing force gusset bracing means, it mainly comprises four gussets 1, connector 2 and high-strength prestressed bolt 3, the two ends of every gusset 1 are fixed wtih connector 2, and high-strength prestressed bolt 3 is joined together to form a closed loop bracing means suitable with being reinforced member section by connector 2 by two adjacent gussets 1.
Between described adjacent two gussets 1, with at least one above high-strength prestressed bolt 3, link together.
Described gusset 1 is formed at end vertical welding by two rectangular steel plates together or by a rectangular steel plates bending.
Between described connector 2 and gusset 1, must take to be connected reliably measure, guarantee effectively to transmit the pulling force of high-strength prestressed bolt 3.
During concrete installation, as shown in Figure 2, prestressing force gusset bracing means 4 is arranged on the outside that is reinforced member 5.
The present invention can be used in various building structure, such as frame construction, shear force of frame wall construction, shear wall structure, the beam and column that can be used in stiffening frame, also can be used in and in shear wall structure, reinforce linking beam, not only can improve the bearing capacity, rigidity and the ductility that are reinforced member, and can effectively to being reinforced member, apply transverse prestress, easy construction, be easy to normalized production, will be widely used in seismic hardening field.
