Description

Technical Field

[0001] The present application relates to the field of construction engineering, and particularly to a reinforcement structure for a building structure and an installation method for the reinforcement structure. Background Art

[0002] The loop-shaped residence is a building with distinct characteristics of the times. It was once highly regarded for its unique shape, exclusive atrium space, and open community with Western characteristics. However, in actual use, problems such as poor north-south permeability, evening sunlight, low utilization rate of the atrium space, and fire evacuation hazards have emerged. Neither its economy nor its livability conforms to the mainstream housing concept in our society. Therefore, it has gradually been replaced by more cost-effective unit high-rise residences. The existing loop-shaped residences are also facing renovation as the number of years of use increases and the materials age.

[0003] During the renovation of existing loop-shaped residences, the walls, reinforcement beams, and floors are usually reinforced. The main reinforcement method is to install steel plates on the surfaces of the floors and reinforcement beams. This connection form is safe and reliable, and the beam structure will not cause loss of bearing capacity due to variable cross-sections. Then, cross beams are installed on the steel plates outside the reinforcement beams, and then aisles are built on the cross beams to connect the two opposite buildings of the loop-shaped residence.

[0004] The present invention can achieve safe, firm, and reliable connection of the construction joints between the steel-bonded reinforcement beam and the steel corbel, shorten the construction period, improve the project quality, save labor costs, and eliminate potential safety hazards.

[0005] In the process of implementing the present invention, the inventor found that at least the following problems exist in this technology: The aisle is fixedly connected to the steel plate on the beam. Due to the large mass of the aisle, not only is the construction difficult, but also the stability and firmness at the end joints are poor. Summary of the Invention

[0006] In order to facilitate the installation of the cross beam and the subsequent aisle, and at the same time improve the stability of the structure, the present application provides a reinforcement structure for a building structure and an installation method for the reinforcement structure.

[0007] In a first aspect, a reinforcement structure for a building structure provided by the present application adopts the following technical solution:

[0008] A reinforcement structure for a building structure includes a reinforcement steel plate that wraps the upper and lower surfaces of the floor and the periphery of the reinforcement beam. Vertical tension bolts for connecting the upper and lower reinforcement steel plates are provided on the floor, and a plurality of horizontal tension bolts for connecting the opposite two reinforcement steel plates are provided on the reinforcement beam. A horizontally arranged support steel plate is fixed to the bottom of the reinforcement beam, the reinforcement steel plate on the reinforcement beam is fixed to the support steel plate, a steel corbel assembly is fixed to the reinforcement steel plate on the outer side wall of the reinforcement beam, the lower end of the steel corbel assembly is fixed to the reinforcement steel plate, and both ends of the cross beam are installed on the steel corbel assembly.

[0009] By adopting the above technical solution, the reinforcement steel plates fix the floor slab and the reinforcement beam through the tension bolts, improving the overall stability. The setting of the supporting steel plates plays a supporting role, reducing the possibility of bottom subsidence. At the same time, the cross beam is arranged on the steel bracket assembly, facilitating the installation of the cross beam.

[0010] Optionally, grouting material for filling the gaps is poured into the reinforcement beam between the reinforcement steel plates.

[0011] By adopting the above technical solution, the grouting material is used to fill the voids inside the reinforcement beam, improving the stability of the reinforcement beam.

[0012] Optionally, the steel bracket assembly includes a plurality of connecting steel plates fixed on the reinforcement steel plates. The plurality of connecting steel plates are arranged vertically and fixedly connected to the reinforcement steel plates on the outer side of the reinforcement beam. A positioning steel plate connecting the plurality of connecting steel plates is fixed at the upper end of the connecting steel plates. The positioning steel plate is arranged horizontally and the side wall of the positioning steel plate is fixed to the reinforcement steel plate on the outer side wall of the reinforcement beam. A sliding table is arranged on the upper end surface of the positioning steel plate, and the end of the cross beam is installed on the sliding table.

[0013] By adopting the above technical solution, the staff first place one end of the two cross beams on the sliding table, and the other end rotates and rises. When it rotates to the horizontal position, the sliding table slides towards the opposite sliding table, connecting the cross beam to the two opposite sliding tables, facilitating the installation of the cross beam.

[0014] Optionally, a guide rail is fixed on the upper end surface of the positioning steel plate. The guide rail is arranged horizontally and extends along the direction perpendicular to the reinforcement steel plate on the outer side of the reinforcement beam. A sliding groove for sliding and clamping the guide rail is opened on the lower end surface of the sliding table.

[0015] By adopting the above technical solution, the setting of the guide rail limits the movement direction of the sliding table to a certain extent, preventing the sliding table from moving in other directions and causing the cross beam to slip.

[0016] Optionally, an installation groove is opened on the upper end surface of the sliding table. The installation groove penetrates the sliding table along the side close to the cross beam. An installation plate that rotates in the vertical direction is connected in the installation groove through a rotating shaft. When one end of the cross beam is placed on the installation plate and rotates with the installation plate, the other end gradually rises. A limiting mechanism is arranged on the sliding table to prevent the installation plate from rotating when the cross beam is horizontally arranged.

[0017] By adopting the above technical solution, when the cross beam rotates to the horizontal position, under the action of the limiting mechanism, the installation plate is positioned to prevent the installation plate from continuing to rotate, improving the stability of the overall structure.

[0018] Optionally, the limiting mechanism is slidably arranged on a lifting plate in the installation groove. A lifting spring for pushing the lifting plate upward is arranged in the installation groove. A plurality of guiding grooves are formed in the sliding table. A plurality of guiding plates are slidably arranged in the guiding grooves. A guiding rod connecting the plurality of guiding plates is arranged on the guiding plates. A guiding block is fixed on the guiding rod. A guiding surface is formed on the guiding block. The lower end of the lifting plate abuts against the guiding surface. When the mounting plate rotates to the horizontal position, the lifting plate is pushed downward. The lifting plate acts on the guiding surface to push the guiding plate to slide and support on the other side of the mounting plate.

[0019] By adopting the above technical solution, when the cross beam rotates to the horizontal position, the mounting plate squeezes the lifting block, so that the lifting block pushes the guiding block and the guiding plate to move. The guiding plate moves to the other side of the rotating shaft of the mounting plate, and the mounting plate plays a certain supporting role.

[0020] Optionally, a plurality of clamping grooves are formed in the opposite inner side walls of the installation groove. A receiving groove is formed in the side wall of the mounting plate. A clamping block is slidably arranged in the receiving groove. A clamping spring for pushing the clamping block into the clamping groove is fixed in the receiving groove. An inclined surface is formed on the upper end surface of the clamping block. When the mounting plate rotates upward along with the cross beam, the reverse rotation of the mounting plate is prevented.

[0021] By adopting the above technical solution, during the rotation of the mounting plate,

[0022] Optionally, the cross section of the reinforcing beam is a regular polygon.

[0023] By adopting the above technical solution, the setting of the regular polygon is convenient for the installation and positioning of the reinforcing steel plate on the reinforcing beam.

[0024] In a second aspect, the present application further provides an installation method for installing the above-mentioned reinforcement structure, including the following steps:

[0025] S1. Install a support steel plate at the bottom of the reinforcing beam;

[0026] S2. Install a reinforcing steel plate on the reinforcing beam and the floor slab, and fix it with a tie bolt;

[0027] S3. Install the steel corbel assembly on the positioning support steel plate and the positioning steel plate;

[0028] S4. Pour the concrete grouting material between the steel plate and the reinforcing beam to fill the gap densely;

[0029] S5. Place one end of the cross beam on one of the mounting plates, and slowly raise the other end of the cross beam until the cross beam moves to the horizontal position;

[0030] S6. Move the sliding table towards the opposite sliding table direction to facilitate the connection of the cross beam to the two sliding tables.

[0031] By adopting the above technical solution, the reinforced steel plates play a certain role in reinforcing the reinforced beams and floors, improving the stability and safety of the overall structure. The setting of the steel corbel assemblies facilitates the installation of the cross beams. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0038] The following further elaborates on the present application Figures 1-4 in further detail with reference to the attached drawings.

[0039] An embodiment of the present application discloses a reinforcement structure for a building structure. Referring to Figure 1 , reinforcement steel plates 3 are fixed on the upper and lower surfaces of the floor 1, and the same reinforcement steel plates 3 are fixed around the reinforced beam 2 with a square cross-section. The reinforcement steel plates 3 wrap the reinforced beam 2. The two reinforcement steel plates 3 on the floor 1 are fixed by passing vertical tie bolts 4 through the floor 1. The four reinforcement steel plates 3 of the reinforced beam 2 are grouped in pairs, and the same group of reinforcement steel plates 3 are fixed by horizontal tie bolts 5. Grout is poured into the reinforced beam 2 between the reinforcement steel plates 3. The grout can be selected from cement, concrete, etc. for filling the gaps in the reinforced beam 2.

[0040] Referring to Figure 1 and Figure 2, a horizontally arranged support steel plate 6 is fixed on the ground at the bottom of the reinforcement beam 2, and the lower end of the reinforcement steel plate 3 on the reinforcement beam 2 is welded to the upper end face of the support steel plate 6. A steel corbel assembly is arranged on the upper end face of the support steel plate 6, and both ends of the cross beam 25 are fixed to two steel corbel assemblies at the diagonals of the opposite two buildings of the circular building.

[0041] Refer to Figure 1 and Figure 2 , the steel corbel assembly includes a plurality of connecting steel plates 7 welded to the reinforcement steel plate 3 on the outer side of the reinforcement beam 2. The plurality of connecting steel plates 7 are arranged vertically, and the lower ends of the connecting steel plates 7 are welded to the support steel plate 6. A positioning steel plate 8 is fixed to the upper ends of the connecting steel plates 7. The positioning steel plate 8 is arranged horizontally and connects the plurality of connecting steel plates 7. The side wall of the positioning steel plate 8 is welded to the reinforcement steel plate 3 on the outer side of the reinforcement beam 2.

[0042] Refer to Figure 1 and Figure 2 , a sliding table 9 is arranged on the upper end face of the positioning steel plate 8, and the end of the cross beam 25 is installed on the sliding table 9. A guide rail 10 is fixed to the upper end face of the positioning steel plate 8. The cross section of the guide rail 10 is in the shape of a "T", and the guide rail 10 is arranged horizontally and extends along the direction perpendicular to the reinforcement steel plate 3 on the outer side of the reinforcement beam 2. A sliding groove 11 is opened on the lower end face of the sliding table 9, and the inner wall of the sliding groove 11 is attached to the side wall of the guide rail 10. When the sliding table 9 is connected to the guide rail 10, the lower end face of the sliding table 9 abuts against the upper end face of the positioning steel plate 8.

[0043] Refer to Figure 1 and Figure 2 , an installation groove 12 is opened on the upper end face of the sliding table 9. The installation groove 12 penetrates through the sliding table 9 along the direction close to the cross beam 25. An installation plate 13 is rotatably connected in the installation groove 12 through a rotating shaft, and the installation plate 13 can rotate in the vertical direction. One end of the cross beam 25 is placed on the installation plate 13, and the other end of the cross beam 25 rotates upward in the vertical direction and drives the installation plate 13 to rotate upward to ensure the contact area between the cross beam 25 and the installation plate 13 and reduce the local pressure.

[0044] Refer to Figure 1 , Figure 2 and Figure 3, a limiting mechanism is provided on the sliding table 9 to prevent the mounting plate 13 from rotating when the cross beam 25 connects the two sliding tables 9 and is horizontally arranged. The limiting mechanism includes a lifting plate 14 slidably arranged in the mounting groove 12. A lifting spring 15 for pushing the lifting plate 14 upward is arranged in the mounting groove 12. A plurality of guide grooves 16 are formed in the sliding table 9 along the direction parallel to the cross beam 25. A plurality of guide plates 17 are slidably arranged in the guide grooves 16. A guide rod 18 connecting the plurality of guide plates 17 is arranged on the guide plates 17. A guide block 19 is fixed on the guide rod 18. A guide surface 20 is formed on the upper end surface of the guide block 19, and the guide surface 20 slopes downward. The lower end of the lifting plate 14 abuts against the guide surface 20. When the mounting plate 13 gradually rotates to the horizontal position, the lower end surface of the mounting plate 13 pushes the lifting plate 14 downward. The lifting plate 14 acts on the guide surface 20, causing the guide block 19 to push the guide plate 17 to slide out of the guide groove 16. When the mounting plate 13 rotates to the horizontal position, the lifting plate 14 and the plurality of guide plates 17 are respectively located on both sides of the rotation axis of the mounting plate 13 and support the mounting plate 13.

[0045] Referring to Figure 3 and Figure 4 , a plurality of clamping grooves 21 are formed in the opposite inner side walls of the mounting groove 12, and the plurality of clamping grooves 21 are evenly distributed in the height direction. Receiving grooves 22 are formed in the two side walls of the mounting plate 13 parallel to the cross beam 25. A clamping block 23 is slidably arranged in the receiving groove 22. A clamping spring 24 for pushing the clamping block 23 to be clamped into the clamping groove 21 is fixed in the receiving groove 22. An inclined surface sloping downward is formed on the upper end surface of the clamping block 23. Due to the setting of the inclined surface, when the clamping block 23 moves upward, the inner side wall of the clamping groove 21 can push the clamping block 23 to move into the clamping groove 21 and prevent the mounting plate 13 from rotating in the opposite direction. When the mounting plate 13 rotates upward along with the cross beam 25, the clamping blocks 23 are respectively clamped with different clamping grooves 21 to prevent the mounting plate 13 from rotating in the reverse direction.

[0047] S1. Install the support steel plate 6 at the bottom of the reinforcement beam 2;

[0048] S2. Install the reinforcement steel plate 3 on the reinforcement beam 2 and the floor slab 1, and drill holes in the floor slab 1 and the reinforcement beam 2, and connect the reinforcement steel plate 3 through the vertical tie bolts 4 and the horizontal tie bolts 5;

[0049] S3. Weld the connecting steel plate 7 to the support steel plate 6 and the reinforcement steel plate 3, then install the positioning steel plate 8 on the connecting steel plate 7 and the reinforcement steel plate 3, and then install the sliding table 9 on the positioning steel plate 8;

[0050] S4. Pour the concrete grouting material between the steel plate and the reinforcement beam 2 to densely fill the gap.

[0051] S5. Place one end of the cross beam 25 on one of the mounting plates 13, and slowly raise the other end of the cross beam 25 until the cross beam 25 moves to a horizontal position. The guide plate 17 and the lifting plate 14 support the mounting plate 13 on both sides of the rotating shaft of the mounting plate 13.

[0052] S6. When the cross beam 25 turns to the horizontal, move the sliding table 9 connected to the cross beam 25 towards the sliding table 9 on the other side of the cross beam 25, connect the cross beam 25 to the two sliding tables 9, and then reinforce the cross beam 25 and the sliding table 9.
