Description

Technical Field

[0001] This utility model relates to the field of building construction equipment technology, specifically a steel-encased reinforcement structure for concrete beams. Background Technology

[0002] With the acceleration of urbanization and the renovation of old buildings, many reinforced concrete structures have suffered varying degrees of damage after years of use. This damage may be caused by exceeding the building's inherent limits, poor construction quality, or material aging. Therefore, reinforcing existing structures to improve their load-bearing capacity and durability has become particularly important.

[0003] The external steel reinforcement method is a reinforcement method that involves encasing reinforced concrete beams and columns in steel sections and welded steel plates to form a framework, thereby achieving shared load-bearing and restraining the original components. According to the "Code for Design of Strengthening Concrete Structures" (2013 edition), this method is suitable for situations requiring a significant increase in cross-sectional bearing capacity and seismic resistance.

[0004] In common structural designs for external steel reinforcement, flat steel hoops or gussets are welded to the external steel beam at intervals along the beam axis. When a floor slab is present, the U-shaped hoops or their attached bolts should pass through the floor slab and be welded to additional strip steel plates or embedded in the floor slab and then glued in place. In actual renovation projects, there are situations where drilling into the floor slab is not advisable. If the floor slab's construction and finish cannot be damaged, beam reinforcement is necessary. Therefore, a steel-encased concrete beam reinforcement structure needs to be proposed to avoid impacting the floor slab. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a steel-encased reinforcement structure for concrete beams.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a steel-encased reinforced structure for concrete beams, including a bottom reinforcing steel plate, a side reinforcing steel plate, and a supporting component; The bottom reinforcing steel plate is fixed to the bottom surface of the concrete beam, and the side reinforcing steel plate is fixed to the side wall of the concrete beam. The supporting component is fixed to the column at the end of the concrete beam and is fixedly connected to the bottom end face of the steel plate reinforcing the bottom of the beam. As a further technical solution, the supporting component includes supporting ribs and steel clamps; The support rib is located at the center of the bottom of the beam, and the top surface of the support rib is fixed to the bottom surface of the bottom reinforcing steel plate of the beam. The steel clamp is fixed to the column at the end of the concrete beam and is set along the circumference of the column at the end of the concrete beam. The upper edge of the steel clamp abuts against the bottom steel plate of the beam. As a further technical solution, the length of the beam-side reinforcing steel plate is the same as that of the concrete beam, and its lower edge is welded to the upper surface of the beam-bottom reinforcing steel plate.

[0007] As a further technical solution, the length of the bottom reinforcing steel plate is the same as that of the concrete beam, and the width of the bottom reinforcing steel plate is greater than that of the concrete beam.

[0008] As a further technical solution, the vertical distance between one edge of the beam bottom reinforcing steel plate in the width direction and the corresponding edge of the concrete beam in the width direction is 22-27mm; The reinforcing steel plate at the bottom of the beam shares a common transverse centerline with the concrete beam.

[0009] As a further technical solution, the bottom reinforcing steel plate of the beam is fixed to the concrete beam by double rows of chemical anchors.

[0010] As a further technical solution, the beam-side reinforcing steel plate is fixed to the concrete beam by double-row tie rods.

[0011] As a further technical solution, the supporting rib is trapezoidal or rectangular in shape, and is welded to the steel clamp and the beam bottom reinforcing steel plate.

[0012] As a further technical solution, structural adhesive is pressure-injected between the bottom reinforcing steel plate of the beam, the side reinforcing steel plate of the beam, the steel clamp and the contact surface of the concrete beam.

[0013] The beneficial effects of this utility model are: by setting a bottom reinforcing steel plate and a side reinforcing steel plate on the concrete beam, the concrete beam can be reinforced on the one hand, and on the other hand, the force on the concrete beam can be transmitted to the column at the end of the concrete beam and finally to the foundation by combining the side reinforcing steel plate and the supporting rib, thereby improving the bearing capacity and seismic resistance of the concrete beam section. Furthermore, this new type of reinforcement structure design avoids impacting the floor slab and ensures reliable force transmission, while also taking into account construction convenience and cost-effectiveness.

Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0019] Example 1 See Figures 1-3 This embodiment provides a steel-encased reinforcement structure for a concrete beam, including a bottom reinforcement steel plate 1, side reinforcement steel plates 2, and a supporting member 3. The bottom reinforcement steel plate 1 is fixed to the bottom end face of the concrete beam 4, and the side reinforcement steel plates 2 are fixed to the side walls of the concrete beam 4. The supporting member 3 is fixed to the end column 5 of the concrete beam and is fixedly connected to the bottom end face of the bottom reinforcement steel plate 1. This structural design can improve the load-bearing capacity of the concrete beam 4.

[0020] Furthermore, the supporting member 3 includes a supporting rib 31 and a steel clamp 32; the supporting rib 31 is located at the center of the bottom of the beam, and the top surface of the supporting rib 31 is fixed to the bottom surface of the bottom reinforcing steel plate 1 of the beam; the steel clamp 32 is fixed to the concrete beam end column 5 and is arranged along the circumference of the concrete beam end column 5; the outer side wall of the supporting rib 31 abuts against the corresponding outer side wall of the steel clamp 32.

[0021] The structural design of the bottom reinforcing steel plate 1, the side reinforcing steel plate 2, the supporting rib 31, and the steel clamp 32 transmits force to the supporting rib 31 and the steel clamp 32 through the bottom reinforcing steel plate 1 and the side reinforcing steel plate 2, and then to the foundation, thereby improving the bearing capacity of the concrete beam 4 and ultimately achieving the effect of reinforcing the concrete beam 4.

[0022] See Figures 1-3 In the specific implementation process, the bottom end of the beam side reinforcement steel plate 2 is fixed to the upper end face of the beam bottom reinforcement steel plate 1, that is, the beam bottom reinforcement steel plate 1 and the beam side reinforcement steel plate 2 are welded together by a T-shaped connection.

[0023] Furthermore, the length of the bottom reinforcing steel plate 1 is the same as that of the concrete beam 4, and the width of the bottom reinforcing steel plate 1 is greater than that of the concrete beam 4. More preferably, the vertical distance between one edge of the bottom reinforcing steel plate 1 in the width direction and the corresponding edge of the concrete beam 4 in the width direction is 22-27 mm; the bottom reinforcing steel plate 1 and the concrete beam 4 share a common transverse centerline. It can be seen that the width of the bottom reinforcing steel plate 1 is greater than the width of the concrete beam 4, and in the width direction, the edge of the bottom reinforcing steel plate 1 extends beyond the outer edge of the concrete beam 4. For example, the vertical distance between the outer edge of the bottom reinforcing steel plate 1 and the outer edge of the concrete beam 4 is 25 mm.

[0026] See Figures 1-3 In the specific implementation process, the supporting rib 31 is trapezoidal or rectangular in shape and is welded to the steel clamp 32 and the beam bottom reinforcing steel plate 1. That is, the bottom end face of the supporting rib 31 is welded to the bottom end face of the beam bottom reinforcing steel plate 1, and the side wall of the supporting rib 31 is welded to the steel clamp 32.

[0027] The steel clamp 32 can be welded to the corner of the concrete beam end column 5; it should be noted that the steel clamp 32 is fixed to the concrete beam end column 5 by chemical anchors 6, and the upper edge of the steel clamp 32 is close to the bottom end face of the beam bottom reinforcing steel plate 1.

[0028] It should be noted that the number of the support ribs 31 is at least two, and is determined according to the design requirements; that is, multiple ribs may be provided.

[0029] See Figures 1-3 In the specific implementation process, structural adhesive is injected between the bottom reinforcing steel plate 1, the side reinforcing steel plate 2, the steel clamp 32 and the concrete beam 4.

[0030] It should be noted that in this embodiment, the materials of the beam bottom reinforcing steel plate 1, the beam side reinforcing steel plate 2, the supporting rib 31, and the steel clamp 32 can all be steel, such as steel plate.

[0031] This embodiment is implemented as follows: S1. Cut the steel plate 1 for the bottom of the beam, the steel plate 2 for the side of the beam, the supporting rib 31, and the steel clamp 32 according to the actual size of the concrete beam structure and drill holes. Also, treat the rust and uneven parts on the surface of the steel. S2. If the concrete beam has local defects and cracks, repair and seal them with structural adhesive.
