Description

TECHNICAL FIELD

[0001] The utility model relates to the field of building reinforcement technology more specifically, relate to a reinforcing connecting device of building structure. BACKGROUND

[0002] In the building structure, in the industrial plant, this kind of connecting mode is widely used, for example, heavy machinery manufacturing plant, vertical steel frame column and horizontal steel frame beam connection constitute the frame structure of plant, these frames are used to support the roof and crane beam structure of plant, crane beam needs to bear the weight of crane and hoist heavy object, and it passes through horizontal steel frame to transmit load to vertical steel frame, and finally to base, in structural mechanics, when force acts on structure, it needs reasonable path to transmit and distribute these forces, for the 90 degree vertical steel frame and horizontal steel frame connecting place, the force transmission mode is relatively complex, vertical steel frame mainly bears axial force such as gravity, and the force that horizontal steel frame bears can include lateral force such as wind force, earthquake force generated side force etc., at the connecting place, these different direction forces need to be redistributed and transmitted to base and other support structures, for example, the frame structure in building, vertical steel frame column bears the weight from the upper floor, horizontal steel frame beam bears the load from the floor, including the vertical force generated by the weight of personnel, furniture etc., and the horizontal force generated by wind, earthquake etc., at beam-column connection, the load on the beam needs to be transmitted to the column, if not reinforced, it can cause local stress too large, beyond the allowable stress range of material, thereby causing the damage of connecting part.

[0003] The Chinese patent application No. CN222045188U provides a building structure reinforcing device, which can realize the overturning of the reinforcing plate through the setting of the overturning mechanism, and the upward movement of the extrusion plate driven by the threaded rod. Since one side of the reinforcing plate is inclined, the reinforcing plate can be overturned and the angle can be adjusted when the extrusion plate moves upward, thereby increasing the convenience of reinforcing buildings with an inclined angle and improving the application range of building reinforcement. However, the above-mentioned scheme can only reinforce some niche inclined buildings and cannot reinforce most frame structure support columns. Due to the differences in geometry and stress mode of vertical steel frames and horizontal steel frames, stress concentration is easily generated at their connection parts. Stress concentration refers to the phenomenon that the stress in a local area of a structure is much higher than the average stress. At the connection parts, the stress increases sharply due to factors such as changes in the cross-sectional shape of the components and the direction of the force. According to the theory of elastic mechanics, the stress concentration coefficient increases when there is a sharp change in the geometry of the components, such as the corners of the connection parts. This stress concentration may cause fatigue cracks to first appear at the connection parts. For example, in steel structure buildings that bear repeated wind loads or dynamic loads, the material at the stress concentration point is prone to fatigue damage at a lower cycle count. Once a crack appears, the crack will rapidly expand under the action of continuous load, eventually leading to connection failure and endangering the safety of the entire structure. Therefore, the connection parts need to be reinforced after a period of use.

[0004] Therefore, a reinforcing connection device for building structures is proposed to solve the above problems. Invention content

[0005] To overcome the shortcomings of the prior art, the purpose of the present application is to provide a reinforcing connection device for building structures. The vertical building support assembly and its components can be used to reinforce the horizontal steel frame beam. If the horizontal steel frame beam needs to continuously bear dynamic loads, such as large stamping machines, compressors, and generators, these electrical appliances will generate a large vibration. Taking a stamping machine as an example, the punch rapidly descends and ascends during stamping operation, which generates a huge impact force on the machine body and foundation. This impact force is periodic, and it is first buffered by the toughness of the horizontal steel frame beam, and then transmitted to the connection part. Through the internal circular sliding limiting block and the tension spring of the vertical building support assembly, the reaction force of the tension spring is used to cooperate with the toughness of the horizontal steel frame beam to resolve a part of the impact force, thereby further improving the practicability and reinforcing the connection part.

[0006] The above technical purpose of the present application is achieved through the following technical solutions:

[0009] Further, the supporting reinforcing connecting assembly comprises a triangular supporting block, a lead screw is rotatably connected to the middle part of the triangular supporting block, an adjusting block is arranged on the middle part of the lead screw through a screw sleeve, and a pair of mutually symmetrical hinge rods are hingedly connected to the middle part of the adjusting block.

[0010] Further, a connecting sleeve plate is fixedly connected to each of the pair of right-angle edges of the triangular supporting block, a stress adjusting plate is rotatably connected to the end of each of the pair of connecting sleeve plates away from each other, a connecting protrusion is fixedly connected to the end of each of the pair of stress adjusting plates close to each other, and the ends of the pair of connecting protrusions are hingedly connected to the ends of the pair of hinge rods, respectively.

[0011] Further, the receiving mounting assembly comprises an upper clamping block, a lower clamping block is arranged at the lower end of the upper clamping block, and the upper clamping block and the lower clamping block are fixedly connected through a bolt.

[0014] Further, a pair of circular through holes are formed in the lower end of the fixed shell, and the stretching rods are arranged to pass through the circular through holes.

[0015] In conclusion, the reinforcing connecting device of the building structure has the following beneficial effects:

[0016] (1) The present scheme can pull and reinforce the cross steel frame beam through the cooperation between the parts of the vertical building support assembly. If the cross steel frame beam needs to continuously bear dynamic load, such as large stamping machine, compressor, generator, these electrical appliances will produce larger vibration. Taking the stamping machine as an example, the punch will rapidly descend and rise during stamping operation, which will generate huge impact force on the machine body and foundation, and the impact force is periodic. The impact force will be transmitted to the cross steel frame beam, first buffered by the toughness of the cross steel frame beam, and then transmitted to the connection. Through the internal circular sliding limiting block and the tension spring of the vertical building support assembly, the reaction force of the tension spring is used to cooperate with the toughness of the cross steel frame beam to resolve part of the impact force, further improve the practicability, and also play a role in reinforcing the connection.

[0017] (2) The present scheme can reinforce the lower end of the vertical steel frame column and the cross steel frame beam through the cooperation between the parts of the support and reinforcement connection assembly. At the same time, cooperating with the rotatable stress adjusting plate, the extrusion of the vertical steel frame column and the cross steel frame beam can be adjusted according to the actual situation. Through the increase of extrusion, the contact between the vertical steel frame column and the cross steel frame beam is more closely, and the friction on the contact surface is increased under the stress state, so that the load can be better transmitted, and the reinforcement effect is further improved.
