Description

Technical Field

[0001] The present application relates to the technical field of frame structure construction engineering, and in particular to a frame beam-column earthquake-resistant reinforcement structure. Background Art

[0002] A frame structure refers to a structure that is composed of beams and columns connected by rigid or hinged joints to form a load-bearing system, that is, a frame composed of beams and columns that jointly resists horizontal and vertical loads that occur during use. The walls of a house with a frame structure do not bear weight, but only serve as enclosure and separation. The beam-column node plays a pivotal role and is the key to transmitting internal forces. Therefore, when the beam-column node is damaged by external forces such as aging of the material or earthquakes, seismic reinforcement maintenance is required to ensure the safety of the building.

[0003] Related technologies, such as a Chinese patent with authorization announcement number CN109537928B, discloses an anti-seismic reinforcement structure for a frame beam and column, wherein the frame column is provided with a variable-section reinforcement section extending outwardly adjacent to the bottom of the frame beam, the beam end reinforcement channel steel plate is matched and surrounded by the frame beam adjacent to the frame column, and is connected and fixed to the floor slab and the variable-section reinforcement section, the energy-absorbing reinforcement part comprises two arc-shaped shear steel plates at perpendicular angles, the lower ends of the two arc-shaped shear steel plates are connected as a whole through an angle steel portion, the angle steel portion is connected and fixed to a corresponding angle of the variable-section reinforcement section, the upper ends of the two arc-shaped shear steel plates are fixed as a whole with the beam end reinforcement channel steel plate, each arc-shaped shear steel plate is bent with a U-shaped buffer groove in the middle, each adjacent two U-shaped buffer groove openings are arranged opposite to each other, and a composite elastic block is tightly fixed between the two by a fastening screw.

[0004] With respect to the above-mentioned related technologies, the applicant has discovered that the lower end of each energy-absorbing reinforcement piece needs to be connected to the upper end of the frame column by bolts, that is, when the energy-absorbing reinforcement piece is subjected to force, the force will be transferred to the frame column through the bolts. When the above-mentioned force is too large, it is easy to cause local damage to the part of the frame column connected with the bolts, resulting in the lower end of the energy-absorbing reinforcement piece being unable to continue to maintain a stable connection with the frame column, affecting the normal use of the energy-absorbing reinforcement piece, and therefore needs to be improved. Summary of the invention

[0005] The purpose of the present application is to provide a frame beam column seismic reinforcement structure, which has the effect of avoiding damage to the frame column. In a first aspect, the present application provides a frame beam column seismic reinforcement structure, which adopts the following technical solution.

[0006] A frame beam-column seismic reinforcement structure includes four groups of energy-absorbing reinforcement members, each of which includes two energy-absorbing support rods, each of which is respectively arranged on each side of the frame column, and the two energy-absorbing support rods constituting the same energy-absorbing reinforcement member are respectively located on two opposite sides of each frame beam, each of which includes a vertical section, an arc section and a horizontal section which are sequentially arranged and connected as a whole, the lower end of the vertical section is fixed to the ground, and the vertical section is connected to the side of the frame column, the arc section is arranged in a quarter circle shape, and the upper and lower ends of the arc section are respectively connected to the horizontal section and the vertical section as a whole, and the horizontal section is connected to the bottom surface of the floor slab.

[0007] Specifically, the energy-absorbing support rods composed of vertical sections, arc sections and horizontal sections can directly reinforce the part of the layer plate close to the frame column, so that the energy-absorbing reinforcement composed of the two energy-absorbing support rods can directly transfer the force on the layer plate to the ground. In this way, there is no need to adjust the construction of the frame column to achieve the effect of reducing the force on the frame beams and columns, thereby indirectly strengthening the frame beams and columns against earthquakes. Moreover, since there is no need to drill holes in the frame columns, no structural damage will be caused to the frame columns. At the same time, when disassembling and replacing, there is no need to worry about secondary damage to the frame beams and columns, which facilitates the restoration of the frame beams and columns to their original state.

[0008] Furthermore, it includes a plurality of fasteners, each of which is arranged along the height direction of the frame column, and each of the fasteners is arranged in a rectangular frame shape, and each side of each fastener is provided with two clearance grooves, and the vertical sections of each energy-absorbing support rod are respectively passed through each clearance groove, and each of the fasteners is sleeved on the frame column.

[0009] Specifically, the vertical sections of each energy-absorbing support rod can be fixed to the frame column through the reinforcement piece, so that when the layer plate vibrates, the energy-absorbing support rod will not shift due to frequent force, thereby ensuring the supporting effect of the energy-absorbing support rod on the layer plate and ensuring the normal use of the energy-absorbing support rod.

[0010] Furthermore, each of the fasteners includes four connection groups, each of the connection groups is respectively connected to each energy-absorbing reinforcement member, each of the connection groups includes two clamping blocks and a plurality of connecting rods, each of the connecting rods is arranged in a vertical direction and horizontally passes through the two clamping blocks, and the two clearance grooves on the same side of the fasteners are respectively arranged on one side surface of the two clamping blocks close to the frame column, and any two adjacent connection groups can be detachably connected.

[0011] Specifically, each connection group corresponds to each energy-absorbing reinforcement member. The clamping block of the connection group can vertically clamp and fix the energy-absorbing support rod on the frame column. The cooperation between the connecting rods can fix each clamping block on the frame column.

[0012] Furthermore, each of the fasteners further includes eight connecting plates and a number of nuts. Each of the connecting plates is sleeved on both ends of each connecting group. A number of through holes for the connecting rods to pass through are provided on each of the connecting plates. Each of the nuts is threadedly connected to the end of each connecting rod. The two connecting plates located at both ends of any connecting group are respectively attached to the opposite side surfaces of the other two connecting groups located at both ends of this connecting group.

[0013] Specifically, by installing connecting plates on both ends of the connecting group, and making the opposite side surfaces of the two connecting plates respectively attached to the connecting groups located at both ends of the above-mentioned connecting group, and then locking nuts on the connecting rods, the effect of fixing the two groups of connecting groups located on the opposite side surfaces of the frame column to the frame column can be achieved.

[0014] Furthermore, a number of rubber buffer pads are also included. Each of the rubber buffer pads is evenly distributed on the vertical section of each energy-dissipating support rod. A groove is provided on one side surface of each of the rubber buffer pads. The vertical section of each energy-dissipating support rod is closely attached to the rubber buffer pad through the groove. The side surface of each rubber buffer pad away from the energy-dissipating support rod is attached to the side surface of the frame column. Specifically, the rubber buffer pad can play a role in buffering and protecting, avoiding the vertical section of the energy-dissipating support rod directly contacting the side surface of the frame column, so that when the fastener fixes the energy-dissipating support rod to the frame column, the relatively hard energy-dissipating support rod will not damage the surface of the frame column.

[0015] Furthermore, four supporting members are also included. Each of the supporting members is respectively installed on each frame beam, and the cross-section of each supporting member is in a "U" shape. Connecting wings that fit the bottom surface of the laminate are provided on both long side edges of each of the supporting members. A number of rollers arranged along the length direction of the supporting member are rotatably connected inside the two connecting wings. The lower side of each roller is attached to the outer wall of the horizontal section of the energy-dissipating support rod.

[0016] Specifically, the horizontal section of the energy-dissipating support rod can directly act on the rollers with the supporting force, and then transfer it to the wing plates through the rollers, and finally transfer it to the laminate through the wing plates, realizing the effect of supporting and strengthening the laminate. The use of the supporting member can play a role in protecting the frame beam, and the use of the rollers can avoid the horizontal section of the energy-dissipating support rod directly causing greater damage to the bottom surface of the laminate when the energy-dissipating support rod is installed.

[0017] Furthermore, inner grooves are provided on the outer wall of each of the rollers. When the horizontal section of the energy-dissipating support rod is connected to the supporting member, the upper side of the horizontal section extends into the inner groove and fits with the inner groove.

[0018] Specifically, the inner groove arranged on the roller can limit and prevent the deflection of the horizontal section, so that after the energy-absorbing support rod is installed, the energy-absorbing support rod is not easily deflected due to vibration, ensuring that the supporting effect of the energy-absorbing support rod on the layer plate is stable.

[0019] In a second aspect, the present application also provides a construction method for the above-mentioned frame beam-column seismic reinforcement structure, which adopts the following technical solution:

Adjust the angle of the horizontal section of each energy-absorbing support rod so that both side surfaces of each frame beam are tightly fitted with the horizontal section of the corresponding energy-absorbing support rod, and then fix the vertical section of each energy-absorbing support rod to the frame column.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 2. Each frame reinforcement is easy to disassemble and use, and can directly transfer the vibration force of the layer plate to the ground, effectively ensuring the earthquake-resistant effect.
