[0002] In the reinforcement and renovation of existing building floor slabs, it is common to add infill walls or place additional equipment on the original structure to change or expand the building's functionality. However, the added load often exceeds the bearing capacity requirements of the old floor slab, necessitating reinforcement treatment.
[0003] In existing technologies, secondary beams are often added to the bottom of the floor slab to strengthen the support of the floor slab. However, since the floor slab and secondary beams have long spans and are usually made of reinforced concrete, the floor slab and secondary beams are formed independently. The connection strength between the two is low, and separation and cracking may occur after a long time. This will reduce the stability and strength of the support for the floor slab and affect the normal living conditions of the residents. Utility Model Content

[0016] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0017] like Figure 1-3As shown, a floor slab and secondary beam reinforcement device includes a first reinforcement member 3 and a second reinforcement member 4 symmetrically arranged in an L-shape on both sides of the secondary beam in the width direction. The secondary beam is located at the bottom of the floor slab and supports the floor slab. The first reinforcement member 3 and the second reinforcement member 4 are arranged on both sides of the secondary beam in the width direction, surrounding the secondary beam and connecting the floor slab and the secondary beam, thus reinforcing the floor slab and the secondary beam. The first reinforcement member 3 and the second reinforcement member 4 have identical structures and are arranged in a mirror-symmetrical manner. The first reinforcement member 3 and the second reinforcement member 4 can be made of metal to form a plate-like structure, increasing the reinforcement between the floor slab and the secondary beam. To increase the contact area and enhance the reinforcement strength, the first reinforcement component 3 includes a horizontal section 31 connected to the bottom surface of the floor slab, a vertical section 32 connected to the side wall of the secondary beam, and multiple fixed columns 21 evenly distributed from top to bottom and passing through the middle of the secondary beam along the width direction. The horizontal section 31 and the vertical section 32 are integrally formed into an L-shaped reinforcement component. The horizontal section 31 is fixedly connected to the bottom of the floor slab by expansion bolts and other connectors. A hole is drilled in the middle of the secondary beam, and multiple fixed columns 21 pass through the secondary beam horizontally along the width direction. Each fixed column 21 is evenly distributed vertically, and the two ends of the fixed columns 21 are respectively... The first and second reinforcing members 3 and 4 are connected and fixed to the vertical section 32, thus forming a reinforcement structure for the floor slab and secondary beams. The fixed column 21 passes through the two vertical sections 32 at both ends and is bolted to them. The bottom end of the vertical section 32 is provided with a base plate 33 that bends and extends towards the bottom surface of the secondary beam. The base plate 33 bends and extends to the bottom of the secondary beam, providing support and increasing the contact area with the secondary beam and its enclosure, thus strengthening the secondary beam's support strength to the floor slab and improving structural stability. Both ends of the fixed column 21 are provided with extensions to the vertical section 32. 2. The threaded section 211 on the outer side, the fixing column 21 is connected and fixed to the vertical section 32 through the threaded section 211 and the locking nut 212. The threaded section 211 is located at both ends of the fixing column 21. It cooperates with the locking nut 212 to connect and fix the vertical section 32 to both sides of the secondary beam, strengthens the connection strength between the first fixing member 3 and the second fixing member 4 and the secondary beam, and strengthens the connection between the floor slab and the secondary beam through the connection between the horizontal section 31 and the floor slab, strengthens the connection strength between the floor slab and the secondary beam, improves the support stability and support strength of the secondary beam to the floor slab, and ensures the normal living of the residents.
[0018] like Figure 2-3As shown, the first reinforcing member 3 has a vertically oriented strip slot 34 in the middle that cooperates with the fixing column 21. The strip slot 34 is vertically oriented and penetrates the first reinforcing member 3 and the second reinforcing member 4, so that when the first reinforcing member 3 and the second reinforcing member 4 are fixed to the secondary beam, the fixing column 21 and the strip slot 34 can be used to pre-position the first reinforcing member 3 and the second reinforcing member 4 and provide lateral restraint. This makes the installation of the first reinforcing member 3 and the second reinforcing member 4 faster and more accurate, improves installation efficiency, and avoids uneven stress caused by misalignment of the installation positions of the first reinforcing member 3 and the second reinforcing member 4, which would affect the reinforcement stability of the secondary beam and the floor slab. A plurality of equally spaced limiting grooves 35 are provided on one side of the strip-shaped slot 34 along the length direction and cooperate with the fixing post 21. The limiting grooves 35 are provided on one side of the strip-shaped slot 34. When the fixing post 21 is located in the strip-shaped slot 34, the first reinforcement 3 and the second reinforcement 4 are moved laterally so that the fixing post 21 is located in the limiting groove 35. The cooperation between the limiting groove 35 and the fixing post 21 forms a longitudinal limit on the first reinforcement 3 and the second reinforcement 4, thereby improving the structural stability of the first reinforcement 3 and the second reinforcement 4 after installation. The width of the strip-shaped slot 34 and the width of the limiting groove 35 are similar to the diameter of the fixing post 21, allowing for a small error.
[0019] like Figure 3-4As shown, the upper side of the limiting groove 35 is provided with a fixed groove 351 and a movable block 36 disposed in the fixed groove 351. The end face of the movable block 36 is provided with an indentation 361 that cooperates with the side wall of the fixed post 21. The fixed groove 351 is provided with a telescopic spring 352 connected to the movable block 36. The movable block 36 can move up and down elastically in the fixed groove 351 by the action of the telescopic spring 352. When the fixed groove 351 is located on the upper side of the limiting groove 35, the fixed post 21 is located in the limiting groove 351 and can pass through the lower side of the limiting groove 351 (i.e., the body of the first reinforcing member 3 and the second reinforcing member 4). The main body provides rigid support to the lower side of the fixed column 21 to ensure support strength, while the movable block 36 is located on the upper side of the limiting groove 351. It can position the fixed column 21 through the concave part 361, which can realize the lateral positioning of the fixed column 21. This makes the installation of the first reinforcement 3 and the second reinforcement 4 faster and more accurate. Moreover, the positioning function and the movable nature of the movable block 36 do not affect the locking nut 212 from which the fixed column 21 is locked to the first reinforcement 3 and the second reinforcement 4. The end face of the locking nut 212 is larger than the width of the limiting groove 351, which can complete the locking of the fixed column 21 and the first reinforcement. The locking and fixing between the first reinforcement 3 and the second reinforcement 4, while installing the first reinforcement 3 and the second reinforcement 4 to both sides of the secondary beam, since the fixed column 21 is fixed to the secondary beam, the movable block 36 can automatically lift the first reinforcement 3 and the second reinforcement 4 through the telescopic spring 352, ensuring that the horizontal section 31 is tightly fitted with the floor slab, realizing the quick installation of the first reinforcement 3 and the second reinforcement 4, making the installation of the first reinforcement 3 and the second reinforcement 4 more labor-saving. The movable block 36 has an inclined guide surface on the side facing the strip slot 34. The guide surface 362 is designed so that when the fixed post 21 moves laterally relative to the first reinforcement 3 and the second reinforcement 4 to contact the movable block 36, the guide surface 362 can guide the fixed post 21, allowing the fixed post 21 to smoothly press the movable block 36 along the guide surface 362, causing the movable block 36 to retract until the fixed post 21 is completely located in the concave part 361 of the movable block 36. At this point, the movable block 36 is moved by the telescopic spring and abuts against the side wall of the fixed post 21. This allows the staff to quickly determine whether the installation is in place, avoiding the trouble of multiple positioning steps.
[0020] like Figure 1-2As shown, the inner curved sides of the first reinforcement 3 and the second reinforcement 4 are provided with L-shaped reinforcement 5. The L-shaped reinforcement 5 can be made of metal or other hard materials. The horizontal part of the L-shaped reinforcement 5 is connected to the horizontal section 31. The horizontal part of the L-shaped reinforcement 5 is directly connected to the horizontal section 31 of the first reinforcement 3 and the second reinforcement 4, forming longitudinal support for the horizontal section 31, which strengthens the structural strength and stability. The outer side of the vertical part of the L-shaped reinforcement 5 is provided with a positioning block 51 located in the strip slot 34 and cooperating with the strip slot 34. The positioning block 51 can form a stable support for the L-shaped reinforcement 5 through the strip slot 34. At the same time, before installing the locking nut 212, the positioning block 51 can fill the strip slot 34 to increase the contact area between the first reinforcement 3 and the second reinforcement 4 and the secondary beam, which can strengthen the overall support strength of the first reinforcement 3 and the second reinforcement 4.
[0021] like Figure 2-3 As shown, the lower ends of the first reinforcement member 3 and the second reinforcement member 4 are provided with support plates 37 that abut against the bottom surface of the secondary beam and the top surface of the base plate 33, respectively. The two ends of the support plates 37 can be bent downwards to abut against the outer sides of the first reinforcement member 3 and the second reinforcement member 4. The support plates 37 are made of metal. The support plates 37 pass through the first reinforcement member 3 and the second reinforcement member 4 and abut against the bottom surface of the secondary beam and the top surface of the base plate 33, respectively, to strengthen the support strength of the base plate 33 for the secondary beam. After the support plates 37 pass through the first reinforcement member 3 and the second reinforcement member 4, the two ends of the support plates 37 are located on the outer sides of the first reinforcement member 3 and the second reinforcement member 4. The two ends of the support plates 37 can be bent downwards by external tools (such as hammers) to make the two ends of the support plates 37 bend downwards and clamp onto the outer walls of the first reinforcement member 3 and the second reinforcement member 4, thereby clamping and fixing the support plates 37 and reinforcing the first reinforcement member 3 and the second reinforcement member 4, improving the structural stability and reliability of the first reinforcement member 3 and the second reinforcement member 4.
[0022] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
