[0016] The present invention provides a civil engineering building structure reinforcement device. It has the following beneficial effects:

[0017] (1) In the present invention, through the cooperation of the bottom plate, frame columns, frame vertical shells, hydraulic rods, ring supports, cross columns, corner brackets, L-shaped plates and sliding rods with the first spring, during the upward movement of the L-shaped plate, it contacts the angle between the cross beam and the wall. Under the action of the extrusion force, the L-shaped plate drives the sliding rod to move downward. The sliding rod slides downward in the sliding opening of the corner bracket, and the sliding groove of the L-shaped plate slides downward on the corner bracket, causing the first spring to start contracting under the action of the pressure. Under the compressive elastic force of the first spring, the L-shaped plate tightly abuts against the angle between the cross beam and the wall, enabling the L-shaped plate to effectively support the angle of the cross beam and preventing the angle where the cross beam is connected to the wall from being damaged due to ineffective support, resulting in cracking of the angle of the cross beam.

[0018] (2) Through the setting of the pressing device in the present invention, the concave block, cylinder and U-shaped rod cooperate with the second spring. The U-shaped rod slides in the cylinder. Under the action of the extrusion force on the second spring on the U-shaped rod, the second spring starts to contract. Under the compressive elastic force of the second spring, the L-shaped plate adheres to the wall, enabling the L-shaped plate to support the walls on both sides of the cross beam and preventing the L-shaped plate from loosening in supporting the angle of the cross beam due to poor support effect on the wall surface.

[0019] (3) Through the setting of the pressing device in the present invention, the ring straight block and the cross plate cooperate with the rubber plate. The cross plate drives the rubber plate to rotate upward. During the upward rotation of the rubber plate, the rubber plate abuts against both sides below the bottom plate, improving the support force on both sides below the bottom plate and preventing the support on both sides below the bottom plate from loosening, resulting in poor support effect on both sides below the cross beam.

[0020] (4) Through the setting of the moisture-proof device in the present invention, the inclined groove plate, support rod and semi-circular plate cooperate with the calcium chloride block. The semi-circular plate drives the calcium chloride block to move upward. The calcium chloride block moves below the cross column, and the calcium chloride block dries the area below the cross column, reducing the oxidation and rusting of the cross column, extending the service life of the cross column, and preventing the support effect of the cross column from decreasing due to easy oxidation and rusting of the cross column.

[0021] (5) Through the setting of the moisture-proof device in the present invention, the bottom arc block and the H-shaped plate cooperate with the semi-circular support. During the upward movement of the semi-circular support, the semi-circular support contacts the area below the cross column, and the semi-circular support abuts against the area below the cross column, preventing the bearing capacity of the cross column from decreasing, resulting in poor load-bearing reinforcement effect of the equipment.

[0032] A hydraulic rod 4 is fixedly installed at the inner bottom end of the frame vertical shell 3. The telescopic end of the hydraulic rod 4 is fixedly connected to the bottom surface of the frame column 2. A ring support 5 is fixed to the outer wall of the hydraulic rod 4, and the outer wall of the ring support 5 is fixedly connected to the inner wall of the frame vertical shell 3. The ring support 5 is used to limit the position of the hydraulic rod 4 in the frame vertical shell 3. At the top of the side where the frame columns 2 are close to each other, a cross column 6 is penetrated and fixedly installed. A corner bracket 7 is fixed to both the left and right ends of the cross column 6. A number of T-shaped plates 601 are arranged on the top surface of the cross column 6. The top surface of the T-shaped plate 601 is fixedly connected to the middle of the bottom surface of the bottom plate 1. The T-shaped plate 601 is used to support the lower part of the bottom plate 1 and improve the support effect on the middle of the bottom surface of the bottom plate 1. A reinforcing rib is arranged between the outer wall of the cross column 6 and the outer wall of the corner bracket 7. Two inclined strip plates 701 are respectively arranged on the inner wall of the corner bracket 7. The inclined strip plates 701 are used to improve the structural strength of the corner bracket 7 so that the corner bracket 7 will not deform during support.

[0033] A sliding opening is formed on the top surface of the corner bracket 7. A sliding rod 9 is slidably installed on the inner wall of the sliding opening of the corner bracket 7. An L-shaped plate 8 is fixed to the top surface of the sliding rod 9. The L-shaped plate 8 is located on the left and right sides of the bottom plate 1. Sliding grooves are respectively formed on the side where the L-shaped plates 8 are close to each other. The inner wall of the sliding groove of the L-shaped plate 8 is in sliding contact with the side where the corner brackets 7 are far from each other. A first spring 10 is fixed to the inner top end of the L-shaped plate 8. The end of the first spring 10 far from the L-shaped plate 8 is fixedly connected to the outer wall of the corner bracket 7. The corner bracket 7 drives the first spring 10 to move upward. The first spring 10 drives the L-shaped plate 8 to move upward. The L-shaped plate 8 drives the sliding rod 9 to move upward. During the upward movement of the L-shaped plate 8, it contacts the included angle between the cross beam. Under the action of the extrusion force, the L-shaped plate 8 drives the sliding rod 9 to move downward. The sliding rod 9 slides downward in the sliding opening of the corner bracket 7. The sliding groove of the L-shaped plate 8 slides downward on the corner bracket 7, so that the first spring 10 starts to contract under the action of the pressure. Under the compression elastic force of the first spring 10, the L-shaped plate 8 tightly abuts against the included angle between the cross beam and the wall, enabling the L-shaped plate 8 to effectively support the included angle between the cross beam. The L-shaped plate 8 is used to support the included angle between the cross beam and the wall. The first spring 10 is sleeved on the sliding rod 9. The elastic force during the compression of the first spring 10 is used to support the included angle between the cross beam and the wall, avoiding cracking and damage of the included angle between the cross beam and the wall due to ineffective support when the structural reinforcement device supports the cross beam of the civil engineering building.

[0034] A pressing device 11 is arranged on the inner wall of the L-shaped plate 8. The pressing device 11 is used to press the L-shaped plate 8 tightly against the wall to improve the stability of the walls on both sides of the cross beam. A moisture-proof device 12 is arranged on the outer wall of the pressing device 11. The moisture-proof device 12 is used to reduce the long-term exposure of the cross column 6 to a humid environment and improve the service life of the cross column 6.

[0035] During actual use, the telescopic end of the hydraulic rod 4 drives the frame column 2 to move upward. The frame column 2 drives the bottom plate 1 to move upward. At the same time, the frame column 2 drives the cross column 6 to move upward. The cross column 6 drives the corner bracket 7 to move upward. The corner bracket 7 drives the first spring 10 to move upward. The first spring 10 drives the L-shaped plate 8 to move upward. The L-shaped plate 8 drives the sliding rod 9 to move upward. During the upward movement of the L-shaped plate 8, it contacts the included angle between the cross beam and the wall. Under the action of pressure, the first spring 10 begins to contract. Under the compression elastic force of the first spring 10, the L-shaped plate 8 tightly abuts against the included angle between the cross beam and the wall, providing elastic support for the included angle of the cross beam.

[0036] Working principle: Since the included angle between the cross beam and the wall is not effectively supported, it is easy to cause cracking and damage to the included angle of the cross beam. When using this device, the construction personnel place the device under the cross beam of the civil engineering building. The reinforcing ribs on the bottom feet 301 are used to improve the support stability of the frame vertical shell 3. The construction personnel start the hydraulic rod 4 in the frame vertical shell 3. The ring support 5 supports the hydraulic rod 4. The telescopic end of the hydraulic rod 4 begins to move upward. The telescopic end of the hydraulic rod 4 drives the frame column 2 to move upward. The frame column 2 slides upward in the frame vertical shell 3. The frame column 2 drives the bottom plate 1 to move upward. The bottom plate 1 drives the protective plate 101 to move upward. The bottom plate 1 moves under the cross beam. The bottom plate 1 supports the lower part of the cross beam. The protective plate 101 moves to the surface of the cross beam. The protective plate 101 protects the surface of the cross beam that is not yet dry. At the same time, the frame column 2 drives the cross column 6 to move upward. The cross column 6 drives the T-shaped plate 601 to move upward. The T-shaped plate 601 supports the lower part of the bottom plate 1, improving the support effect in the middle of the lower part of the bottom plate 1. The cross column 6 drives the corner bracket 7 to move upward. The reinforcing ribs on the corner bracket 7 improve the support strength at both ends of the cross column 6. The inclined strip plate 701 improves the structural strength of the corner bracket 7, ensuring that the corner bracket 7 does not deform during support. The corner bracket 7 drives the first spring 10 to move upward. The first spring 10 drives the L-shaped plate 8 to move upward. The L-shaped plate 8 drives the sliding rod 9 to move upward. During the upward movement of the L-shaped plate 8, it contacts the included angle between the cross beam and the wall. Under the action of the extrusion force, the L-shaped plate 8 drives the sliding rod 9 to move downward. The sliding rod 9 slides downward in the sliding opening of the corner bracket 7. The sliding groove of the L-shaped plate 8 slides downward on the corner bracket 7, causing the first spring 10 to start contracting under the action of pressure. Under the compression elastic force of the first spring 10, the L-shaped plate 8 tightly abuts against the included angle between the cross beam and the wall, enabling the L-shaped plate 8 to effectively support the included angle of the cross beam, preventing the included angle between the cross beam and the wall from not being effectively supported when the device is in use, and thus avoiding the problem of cracking and damage to the included angle of the cross beam caused by the lack of effective support for the included angle between the cross beam and the wall when the structural reinforcement device supports the cross beam of the civil engineering building.

[0037] Please refer to Figures 1-7, on the basis of the above embodiments, in another embodiment of the present invention, the pressing device 11 includes a concave block 111, the concave blocks 111 are respectively fixed on the inner wall of the L-shaped plate 8, a cylinder 112 is hinged on the inner wall of the concave block 111, a U-shaped rod 113 is rotatably installed on the inner wall of the circular opening 201, and both ends of the U-shaped rod 113 are slidably connected to the inner wall of the cylinder 112. The U-shaped rod 113 slides in the cylinder 112, and a second spring 114 is respectively arranged between both ends of the U-shaped rod 113 and the inner wall of the cylinder 112. The elastic force when the second spring 114 is compressed is used to support the L-shaped plate 8 against the wall. Under the action of the extrusion force on the second spring 114 on the U-shaped rod 113, the second spring 114 begins to contract. Under the action of the elastic force of the compressed second spring 114, the L-shaped plate 8 is supported against the walls on both sides of the cross beam, preventing the L-shaped plate 8 from having a poor supporting effect on the wall surface and causing the included angle between the L-shaped plate 8 and the supported cross beam to become loose when the structural reinforcement device supports the cross beam of a civil engineering building.

[0038] During the actual use process, the cylinder 112 rotates upward in the concave block 111, the U-shaped rod 113 rotates downward in the circular opening 201, the U-shaped rod 113 slides in the cylinder 112, the second spring 114 begins to contract, and under the action of the elastic force of the compressed second spring 114, the L-shaped plate 8 is supported against the walls on both sides of the cross beam.

[0039] A straight ring block 115 is respectively fixed on the outer wall of the cylinder 112, a cross plate 116 is fixed on the top surface of the straight ring block 115, and rubber plates 117 are respectively fixed on the top surface of the cross plate 116. The cross plate 116 drives the rubber plates 117 to rotate upward. The rubber plates 117 are used to support both sides of the bottom surface of the bottom plate 1, improving the supporting effect on both sides of the bottom plate 1. During the upward rotation of the rubber plates 117, the rubber plates 117 abut against both sides below the bottom plate 1, preventing the supporting effect on both sides below the bottom plate 1 from being poor due to loose support on both sides below the bottom plate 1 when the structural reinforcement device supports the cross beam of a civil engineering building. A short column 01 is respectively fixed on one side of the straight ring block 115 away from the protection plate 101, and the outer wall of the short column 01 is used to connect the moisture-proof device 12.

[0040] During the actual use process, the concave block 111 drives the straight ring block 115 to rotate upward, the straight ring block 115 drives the cross plate 116 to rotate upward, the cross plate 116 drives the rubber plates 117 to rotate upward, and the rubber plates 117 abut against both sides below the bottom plate 1.

[0041] The moisture-proof device 12 includes an inclined chute plate 121 which is respectively fixed on the outer wall of the short column 01. A support rod 122 is slidably installed on the inner wall of the chute of the inclined chute plate 121. One end of the support rods 122 close to each other is fixed with a semi-circular arc plate 123. A calcium chloride block 124 is fixedly installed at the bottom end inside the semi-circular arc plate 123. The semi-circular arc plate 123 drives the calcium chloride block 124 to move upward. The calcium chloride block 124 moves below the cross column 6. The water absorption capacity of the calcium chloride block 124 is used to reduce the oxidation and rust of the cross column 6. The calcium chloride block 124 absorbs the moisture below the cross column 6, dries the area below the cross column 6, reduces the oxidation and rust of the cross column 6, extends the service life of the cross column 6, and avoids the reduction of the support effect of the cross column 6 caused by the easy oxidation and rust of the cross column 6 during the long-term use of the structure reinforcement device.

[0042] During the actual use process, the short column 01 drives the inclined chute plate 121 to rotate upward. The support rod 122 moves upward in the chute of the inclined chute plate 121. The support rod 122 drives the semi-circular arc plate 123 to move upward. The semi-circular arc plate 123 drives the calcium chloride block 124 to move upward. The calcium chloride block 124 moves below the cross column 6.

[0043] Two bottom arc blocks 125 are fixed at the bottom end inside the semi-circular arc plate 123. The bottom arc blocks 125 are respectively located on the left and right sides of the calcium chloride block 124. In the middle of the top surface of the bottom arc block 125, an H-shaped plate 126 is fixed. A semi-circular arc support 127 is fixed on the top surface of the H-shaped plate 126. The H-shaped plate 126 drives the semi-circular arc support 127 to move upward. During the upward movement of the semi-circular arc support 127, the semi-circular arc support 127 contacts the area below the cross column 6. The bottom surface of the cross column 6 is on the movement track of the outer wall of the semi-circular arc support 127. The semi-circular arc support 127 is used to abut against the area below the cross column 6 to improve the bearing capacity of the cross column 6 and avoid the poor bearing and reinforcement effect of the device caused by the reduction of the bearing capacity of the cross column 6 when the structure reinforcement device supports the cross beam of a civil engineering building.

[0044] During the actual use process, the semi-circular arc plate 123 drives the bottom arc block 125 to move upward. The bottom arc block 125 drives the H-shaped plate 126 to move upward. The H-shaped plate 126 drives the semi-circular arc support 127 to move upward. The semi-circular arc support 127 abuts against the area below the cross column 6 to improve the bearing capacity of the cross column 6.

[0045] Working principle: While the L-shaped plate 8 drives the sliding rod 9 to move downward, the L-shaped plate 8 drives the concave block 111 to move downward, and the concave block 111 drives the cylinder 112 to move downward. Under the restriction of the U-shaped rod 113, the cylinder 112 rotates upward in the concave block 111, and the U-shaped rod 113 rotates downward in the round opening 201. The U-shaped rod 113 slides in the cylinder 112. Under the action of the extrusion force, the second spring 114 on the U-shaped rod 114 starts to contract. Under the compression elastic force of the second spring 114, the L-shaped plate 8 adheres to the wall, enabling the L-shaped plate 8 to support on the walls on both sides of the cross beam, preventing the poor support effect of the L-shaped plate 8 on the wall surface during the use of the equipment, and thus avoiding the problem that the support angle of the L-shaped plate 8 on the cross beam of the civil engineering building is loose due to the poor support effect of the L-shaped plate 8 on the wall surface when the structural reinforcement device supports the cross beam of the civil engineering building.

[0046] While the cylinder 112 rotates upward in the concave block 111, the concave block 111 drives the ring straight block 115 to rotate upward, the ring straight block 115 drives the short column 01 to rotate upward, the ring straight block 115 drives the cross plate 116 to rotate upward, and the cross plate 116 drives the rubber plate 117 to rotate upward. During the upward rotation of the rubber plate 117, the rubber plate 117 abuts against both sides below the bottom plate 1, improving the support force on both sides below the bottom plate 1, preventing the loosening of the support on both sides below the bottom plate 1 during the use of the equipment, and thus avoiding the problem that the support effect on both sides below the cross beam is poor due to the loosening of the support on both sides below the bottom plate 1 when the structural reinforcement device supports the cross beam of the civil engineering building.

[0047] While the ring straight block 115 drives the short column 01 to rotate upward, the short column 01 drives the inclined groove plate 121 to rotate upward, the support rod 122 moves upward in the chute of the inclined groove plate 121, the support rod 122 drives the semi-circular arc plate 123 to move upward, the semi-circular arc plate 123 drives the calcium chloride block 124 to move upward, and the calcium chloride block 124 moves below the cross column 6. The calcium chloride block 124 absorbs the moisture below the cross column 6, dries the area below the cross column 6, reduces the oxidation and rust of the cross column 6, extends the service life of the cross column 6, prevents the cross column 6 from being easily oxidized and rusted during the long-term use of the equipment, and thus avoids the problem that the support effect of the cross column 6 decreases due to the easy oxidation and rust of the cross column 6 during the long-term use of the structural reinforcement device.

[0048] While the support rod 122 drives the semi-circular arc plate 123 to move upward, the semi-circular arc plate 123 drives the bottom arc block 125 to move upward, the bottom arc block 125 drives the H-shaped plate 126 to move upward, and the H-shaped plate 126 drives the semi-circular arc support 127 to move upward. During the upward movement of the semi-circular arc support 127, the semi-circular arc support 127 contacts the lower part of the cross column 6, and the semi-circular arc support 127 abuts against the lower part of the cross column 6, improving the bearing capacity of the cross column 6, preventing the bearing capacity of the cross column 6 from decreasing during the use of the equipment, and thus avoiding the problem that the equipment's bearing reinforcement effect is poor due to the decrease in the bearing capacity of the cross column 6 when the structural reinforcement device supports the cross beam of the civil engineering building.
