Description

Technical Field

[0001] This utility model relates to the field of building equipment technology, and in particular to a U-shaped anchoring clamp for reinforcing beams and columns. Background Technology

[0002] my country still has a large number of existing concrete frame structures built in the last century. Due to factors such as material carbonization, steel corrosion, cumulative earthquake damage, and increased loads, beam-column joint areas commonly exhibit problems such as crack propagation and insufficient shear capacity. According to statistics from the Ministry of Housing and Urban-Rural Development, approximately 35% of urban buildings require seismic reinforcement, with beam-column joint reinforcement accounting for over 60% of these. An increasing number of buildings are approaching their aging stage and require reinforcement.

[0003] In the reinforcement of old buildings, steel plate bonding is commonly used to avoid sacrificing too much space. This method is suitable when increasing the cross-sectional dimensions of the original component is not permitted. This method is simple to construct, has a short construction period, and minimal impact on production and daily life. However, it mainly relies on filling mortar or adhesive to bond the steel plate to the original component. Therefore, pressure must be applied to the steel plate during the curing process. Without pressure fixation, voids may form within the adhesive layer, reducing the load-bearing capacity and stability of the reinforced structure. Current technology typically involves drilling holes in the steel plate surface after bonding it to the original component, then inserting bolts for pressure fixation. Bolt reinforcement causes damage to the original component, affecting its load-bearing capacity, and the pressure fixation effect is not ideal, making it difficult to achieve uniform pressure.

[0004] Therefore, there is a need for a U-shaped anchor clamp that can provide both pressure fixation and connection capabilities. Summary of the Invention

[0005] The main purpose of this utility model is to provide a U-shaped anchoring clamp for reinforcing beams and columns, which aims to solve the problem that the existing steel-bonded reinforcement method has insufficient pressure fixing and connection capacity with the original component.

[0006] To achieve the above objectives, the present invention proposes a U-shaped anchoring clamp for reinforcing beams and columns, comprising:

[0007] The side panel assembly includes two symmetrically arranged L-shaped side panels. The side panels have preset holes arranged along the extension direction of the side panels. The side panels also have anti-slip pads arranged on opposite sides of the two side panels.

[0008] The base plate is vertically connected to the side plate. The base plate has multiple connection holes, which are evenly spaced along the extension length of the base plate. The side plate assembly and the base plate enclose a reinforced space.

[0009] An auxiliary reinforcing plate, which is cross-shaped, includes a vertical section and a horizontal section, which are vertically connected. At least one end of the vertical section is connected to the side plate, and at least one end of the horizontal section is connected to the bottom plate. The auxiliary reinforcing plate is provided with a plurality of sliding groove holes, which are evenly spaced along the extension direction of the vertical and horizontal sections.

[0010] Preferably, the side plate has a connecting surface and a reinforcing surface, the connecting surface and the reinforcing surface are perpendicular to each other, the anti-slip pad is disposed on the side of the reinforcing surface facing the reinforcing space, the preset hole is opened on one side of the connecting surface, and the bottom plate abuts against the connecting surface.

[0011] Preferably, the U-shaped anchoring clamp for reinforcing beams and columns further includes multiple pressure pads, which are disposed on the side of the base plate near the reinforcement space along the extension direction of the base plate.

[0012] Preferably, there are multiple anti-slip pads, which are spaced apart along the extension direction of the reinforced surface. The anti-slip pads on the two symmetrically arranged side plates are staggered and opposite each other. Anti-slip teeth are provided on the side of each anti-slip pad facing the reinforced space.

[0013] Preferably, the U-shaped anchoring clamp for reinforcing beams and columns further includes a fixing component, which includes a first fixing bolt and a second fixing bolt. The first fixing bolt is sequentially inserted into the preset hole, the connecting hole, and the sliding groove hole, so that the auxiliary reinforcing plate is connected to the bottom plate and the side plate. The second fixing bolt is inserted into the sliding groove hole and the preset hole, and the auxiliary reinforcing plate is connected to the side plate through the second fixing bolt.

[0014] Preferably, the fixing assembly further includes a pre-tightening spring, which is disposed on the base plate at a position corresponding to the first fixing bolt. One side of the pre-tightening spring abuts against the first fixing bolt, and the other side of the pre-tightening spring abuts against the base plate.

[0015] This utility model's U-shaped anchoring clamp for reinforcing beams and columns creates a reinforcement space by using side plates and a bottom plate to enclose the space. At the same time, an auxiliary reinforcement plate is used to reinforce the connection between the side plates and the bottom plate. The installation process does not require chiseling the concrete surface or damaging the original components, providing good protection for the original components. It also eliminates the need for welding and bonding, improving construction efficiency. It can provide pressure fixing and connection capabilities. After the steel bonding reinforcement is completed, this utility model can be disassembled, reducing construction costs. Attached Figure Description

[0028] In existing technologies, steel plate bonding reinforcement projects require pretreatment of the contact surfaces between the concrete component and the steel plate. The steel plate is then cut and welded on-site according to design dimensions to obtain steel components. These steel components are pre-attached to the surface of the concrete component, holes are drilled in the concrete, and bolts are used to fix the steel components to the surface. This process requires manual chiseling of the original component, damaging its integrity. Finally, structural adhesive is applied to the contact area between the steel component and the concrete component and allowed to cure. During curing, the area between the steel component and the adhesive coating needs to be tapped to remove air bubbles before the steel plate bonding process is complete. However, the existing method of using bolts to pressurize and fix the steel plate is difficult to guarantee uniform pressure and requires regular checks on the anchor bolts. This method has excessively high construction requirements, unstable pressure effects, and can cause some damage to the original component, making it difficult to protect historically valuable old buildings.

[0029] Based on this, the present invention proposes a U-shaped anchoring clamp 1000 for reinforcing beams and columns, comprising: a side plate assembly 100, the side plate assembly 100 including two symmetrically arranged L-shaped side plates 110, the side plates 110 having preset holes 111 arranged along the extension direction of the side plates 110, the side plates 110 also having an anti-slip pad layer 112, the anti-slip pad layer 112 being disposed on opposite sides of the two side plates 110; a bottom plate 200, the bottom plate 200 being perpendicularly connected to the side plates 110, the bottom plate 200 having multiple connecting holes 210 arranged along the bottom plate 200. The extension lengths are evenly spaced, and the side plate assembly 100 and the bottom plate 200 enclose a reinforced space; the auxiliary reinforcing plate 300 is cross-shaped and includes a vertical section 310 and a horizontal section 320. The vertical section 310 and the horizontal section 320 are vertically connected. At least one end of the vertical section 310 is connected to the side plate 110, and at least one end of the horizontal section 320 is connected to the bottom plate 200. The auxiliary reinforcing plate 300 is provided with a plurality of sliding groove holes 330, which are evenly spaced along the extension direction of the vertical section 310 and the horizontal section 320.

[0030] It is understandable that, such as Figures 1-5 As shown, taking the reinforcement of a horizontal beam in a building as an example, if the beam to be reinforced is a horizontal beam in an old building, and the interior space of the old building needs to be preserved as much as possible, the horizontal beam needs to be reinforced using a steel-bonded reinforcement method. Specifically, the operator needs to cut and prepare the corresponding reinforcement steel parts according to the specific dimensions of the beam to be reinforced. After attaching the reinforcement steel parts to the concrete surface of the beam, structural adhesive is used to pre-bond the reinforcement steel parts to the concrete surface. Then, the U-shaped anchoring clamp 1000 disclosed in this utility model is used to pressurize and fix the steel parts until the structural adhesive cures. During the curing process of the structural adhesive, the U-shaped anchoring clamp 1000 can be lifted by jacks or other supports and then attached to the steel parts to achieve appropriate unloading. Finally, after the structural adhesive has cured, the operator can disassemble the U-shaped anchoring clamp 1000, reducing construction costs. Furthermore, this utility model enables non-destructive installation and provides redundant anchoring through the auxiliary reinforcement plate 300, strengthening the integrity protection of the original component and the reinforcement effect.

[0031] In this embodiment, two symmetrically arranged L-shaped side plates 110 are positioned opposite each other. An anti-slip pad layer 112 is disposed on one side of each side plate 110. The anti-slip pad layer 112 is used to contact the concrete or steel surface, increasing the coefficient of friction and reducing the need for workers to roughen the workpiece or concrete surface, thus reducing construction requirements and improving construction efficiency. An auxiliary reinforcing plate 300 is disposed at the connection between the side plate 110 and the base plate 200, forming a multi-point dispersed anchoring design based on the frictional clamping between the base plate 200 and the bottom surface of the beam / column, the multi-point dispersed anchoring formed by the symmetrically arranged side plates 110, and the multi-level fixing design formed by the adhesive and the beam / column surface, thereby enhancing the anchoring capacity.

[0032] In one embodiment, the side plate 110 is provided with a connecting surface 113 and a reinforcing surface 114. The connecting surface 113 and the reinforcing surface 114 are arranged perpendicularly. The anti-slip pad layer 112 is provided on the side of the reinforcing surface 114 facing the reinforcing space. The preset hole 111 is opened on one side of the connecting surface 113. The bottom plate 200 abuts against the connecting surface 113.

[0033] In this embodiment, the connecting surfaces 113 of the two oppositely arranged side plates 110 are on the same horizontal plane, and the reinforcing surfaces 114 are oppositely arranged. The two opposite reinforcing surfaces 114 are used to clamp the vertical surfaces of the concrete beam and the steel component. When the steel component and the concrete component are bonded together with structural adhesive or mortar, the two opposite reinforcing surfaces 114 are used to apply pressure to the steel component to ensure that no voids or displacement of the steel component occur before the structural adhesive or mortar cures. The preset hole position 111 is set along the length direction of the connecting surface 113, and the auxiliary reinforcing plate 300 is provided with corresponding sliding groove hole position 330. The operator uses screws to sequentially pass through the sliding groove hole position 330 and the preset hole position 111 to connect the auxiliary reinforcing plate 300 and the side plate 110. The bottom plate 200 is provided with corresponding connecting hole position 210. The operator uses screws to sequentially pass through the connecting hole position 210 and the preset hole position 111 to connect the bottom plate 200 and the side plate 110. It is understandable that the extension directions of the groove holes 330 on the vertical section 310 of the cross-shaped structure of the auxiliary reinforcing plate 300 and the groove holes 330 on the horizontal section 320 are perpendicular to each other. The groove holes 330 are rounded rectangles, allowing the bolts to move within the grooves when not fixed, accommodating beam and column width deviations of ±5mm. High-damping rubber pads (3-5mm thick) can also be attached at the connection points between the auxiliary reinforcing plate 300 and the base plate 200 or side plate 110 to absorb vibrations and appropriately compensate for surface unevenness, achieving a good adhesive bonding effect between the adhesive and the steel parts and components.

[0034] In one embodiment, the U-shaped anchoring clamp 1000 for reinforcing beams and columns further includes a plurality of pressure pads 400, which are disposed on the side of the base plate 200 near the reinforcement space along the extension direction of the base plate 200.

[0035] In this embodiment, two pressure pads 400 are attached to the base plate 200, facing the reinforcement space. After the U-shaped anchoring fixture clamps the beam component to be reinforced, the base plate 200 applies pressure to the bottom surface of the beam component via the pressure pads 400, simultaneously isolating the base plate 200 from the steel components to prevent excess adhesive from adhering the U-shaped anchoring fixture 1000 to the steel or concrete components. It is understood that the number of pressure pads 400 can be increased or decreased according to the specific dimensions of the concrete component to meet the requirements of uniform pressure.

[0036] In one embodiment, there are multiple anti-slip pads 112, which are spaced apart along the extension direction of the reinforcement surface 114. The anti-slip pads 112 on the two symmetrically arranged side plates 110 are staggered and opposite to each other. Anti-slip teeth are provided on the side of the anti-slip pads 112 facing the reinforcement space.

[0037] In this embodiment, the anti-slip pads 112 on two symmetrically arranged side plates 110 are connected by adhesive. The anti-slip pads 112 have serrated anti-slip patterns on the side facing the reinforced space. The serrations of adjacent anti-slip pads 112 on the same side plate 110 are opposite in direction. The anti-slip pads 112 are mechanically fixed to the beam and column surfaces by the serrated anti-slip patterns, avoiding openings and protecting the integrity of old buildings.

[0038] In one embodiment, the U-shaped anchoring clamp 1000 for reinforcing beams and columns further includes a fixing component 500, which includes a first fixing bolt 510 and a second fixing bolt 520. The first fixing bolt is sequentially inserted into a preset hole 111, a connecting hole 210, and a sliding groove hole 330, so that the auxiliary reinforcing plate 300 is connected to the bottom plate 200 and the side plate 110. The second fixing bolt 520 is inserted into the sliding groove hole 330 and the preset hole 111, and the auxiliary reinforcing plate 300 is connected to the side plate 110 through the second fixing bolt 520.

[0039] In this embodiment, the first fixing bolt 510 and the second fixing bolt 520 are detachable bolts used to connect the auxiliary fixing plate, the side plate 110, and the bottom plate 200. After the adhesive applied to the surface of the concrete component has cured, the operator can disassemble the first fixing bolt 510 and the second fixing bolt 520 to disassemble and separate the auxiliary reinforcing plate 300, the side plate 110, and the bottom plate 200, which can be easily applied to other costs and reduce production costs.

[0040] In another embodiment, the fixing component 500 may also include chemical bolts, which allow operators to use jacks or other supports to lift and fit the steel components when the U-shaped anchor clamp 1000 needs to be clamped to the beam or column for an extended period of time, and then use chemical bolts to fix the U-shaped anchor clamp 1000 to the roof of the building, providing a long-term fixing effect.

[0041] In one embodiment, the fixing assembly 500 further includes a pre-tensioning spring 530, which is disposed on the base plate 200 at a position corresponding to the first fixing bolt 510. One side of the pre-tensioning spring 530 abuts against the first fixing bolt 510, and the other side of the pre-tensioning spring 530 abuts against the base plate 200.

[0042] In this embodiment, the pre-tightening spring 530 is disposed between the base plate 200 and the first fixing bolt 510. It can be understood that the pre-tightening spring 530 can also be disposed between the second fixing bolt 520 and the side plate 110. The pre-tightening spring 530 is used to apply axial pre-tightening force to the first fixing bolt 510 or the second fixing bolt 520 to improve the fixing effect.

[0043] This utility model's U-shaped anchoring clamp for reinforcing beams and columns creates a reinforcement space by using side plates and a bottom plate. When beams and columns in old buildings require reinforcement, workers can move the U-shaped anchoring clamp to achieve non-destructive fixing of the beams and columns within the reinforcement space, avoiding manual chiseling that could damage the original components. Simultaneously, an auxiliary reinforcement plate provides redundant reinforcement to the connection between the side plates and the bottom plate. The installation process eliminates the need for chiseling the concrete surface or damaging the original components, providing excellent protection for the original components. Furthermore, it eliminates the need for welding and bonding, improving construction efficiency. It provides both pressure fixing and connection capabilities. After steel-bonded reinforcement is completed, this utility model can be disassembled, reducing construction costs.
