Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a reinforced steel structure for the top of a brick wall with a ring beam. Background Technology

[0002] With the rapid development of social modernization, the wall structures of many old buildings are affected by the environment, resulting in a significant reduction in their load-bearing and shear strength, necessitating wall reinforcement. In conventional multi-story brick masonry structures, when reinforcing the walls up to the roof, the reinforcing steel bars need to be fixed by penetrating the roof slab or by embedding them in the roof slab, or by bending the steel bars and embedding them into the ring beam to provide an effective load-bearing point at the top of the wall reinforcement bars. However, this approach causes significant damage to the existing ring beams and roof slabs, posing safety hazards.

[0003] In view of the above, it is necessary to develop a reinforcement structure for brick masonry walls with ring beams. This reinforcement structure can reduce the openings and damage to existing ring beams and roof slabs. Ensuring the stability of the wall reinforcement while ensuring the top of the reinforcement is firmly fixed is a problem that needs to be solved in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a reinforcement structure for the top of a brick wall with a ring beam. This device overcomes the shortcomings of existing technologies, reduces the need for openings and damage to existing ring beams and roof slabs, and ensures the wall reinforcement is stable while ensuring the top of the reinforcement bars is firmly fixed. This invention reduces the amount of work, has high construction efficiency, and is simple and quick to implement.

[0005] To achieve the above objectives, this utility model provides a reinforced steel structure for the top of a brick wall with a ring beam, comprising an existing wall, an existing ring beam, an existing roof slab, reinforcing steel bars, and fixed angle steel. The existing ring beam is fixedly installed on the top of the existing wall, and the two ends of the existing roof slab are laid on the upper part of the existing ring beam. The reinforcing steel bars and the fixed angle steel are respectively arranged on both sides of the existing wall. The fixed angle steel is fixedly installed at the inside corner of the connection between the existing ring beam and the existing roof slab, and the fixed angle steel is fixedly connected to the existing ring beam by through bolts.

[0006] Preferably, the reinforcing bars include horizontal bars, longitudinal bars, and tie bars. The horizontal bars and longitudinal bars are bidirectionally reinforced in the horizontal and vertical directions, respectively. The two ends of the tie bars pass through the existing wall and are fixedly connected to the horizontal bars.

[0007] Preferably, the horizontal and vertical reinforcing bars are laid at equal intervals on the existing wall, with the spacing between two adjacent horizontal reinforcing bars being 200mm, the spacing between two adjacent vertical reinforcing bars being 200mm, and the spacing between two adjacent tie bars being 1200mm.

[0008] Preferably, the transverse and longitudinal bars are both made of Φ6 steel bars, and the tie bars are made of Φ8 steel bars.

[0009] Preferably, the fixing angle steel is an L100×5 equilateral angle steel, and a through hole is provided on one side of the fixing angle steel for connection with the through bolt. The fixing angle steel is welded and fixed to the top of the longitudinal reinforcement.

[0010] Preferably, the through bolt is a φ12 tie bolt, and both ends of the through bolt are provided with nuts for fixing the fixing angle steel, and the inner diameter of the nuts matches the tie bolt.

[0011] Preferably, it also includes cement mortar, wherein the cement mortar is M10 cement mortar, which is sprayed onto the surface of the existing wall by a spraying machine, and the spraying thickness is 35mm.

[0012] Therefore, this utility model, which employs the above-mentioned structure for reinforcing the top of a brick wall with a ring beam, has the following advantages compared to existing technologies: This utility model uses fixed angle steel to fix the top of the reinforcing steel bars on both sides of the existing ring beam as fixing points, avoiding the need to implant a large amount of steel bars into the existing ring beam and roof slab, thus reducing damage. Simultaneously, it ensures that each longitudinal reinforcement bar has a secure fixing point, enhancing the overall stability of the newly added reinforcing steel structure on the existing wall. Furthermore, this utility model offers high construction efficiency, fast speed, small workload, and is simple and quick to implement. Attached Figure Description

[0017] Example Please see Figure 1This is a schematic diagram of the overall structure of an embodiment of a reinforced steel structure for the top of a brick masonry wall with a ring beam according to the present invention. The technical solution provides a reinforced steel structure for the top of a brick masonry wall with a ring beam, including an existing wall 1, an existing ring beam 2, an existing top slab 3, reinforcing steel bars 4, and fixed angle steel 5. In this embodiment, the existing wall 1 is a brick masonry wall with a thickness of 240mm and a brick strength grade of M10. The existing wall 1 is the wall that needs to be reinforced. The existing ring beam 2 is a reinforced concrete ring beam with a cross-sectional dimension of 240×200mm and a strength grade of C25. It is set on the top of the existing wall 1 to enhance the integrity of the brick masonry wall. The existing top slab 3 is a prefabricated hollow top slab with a thickness of 120mm. During installation, both ends are erected on the upper part of the existing ring beam 2. The reinforcing steel bars 4 and fixing angle steel 5 are respectively installed on both sides of the existing wall 1. The fixing angle steel 5 is fixedly installed at the inside corner of the connection between the existing ring beam 2 and the existing roof slab 3. The fixing angle steel 5 is fixedly connected to the existing ring beam 2 by through bolts 6. The reinforcing steel bars 4 include horizontal bars 41, longitudinal bars 42 and tie bars 43. The horizontal bars 41 and longitudinal bars 42 are bidirectionally reinforced in the horizontal and vertical directions. The two ends of the tie bars 43 pass through the existing wall 1 and are fixedly connected to the horizontal bars 41 to reinforce the existing wall 1 and enhance its shear resistance and integrity. The horizontal bars 41 and longitudinal bars 42 are laid at equal intervals on the existing wall 1. The spacing between two adjacent horizontal bars 41 is 200mm, the spacing between two adjacent longitudinal bars 42 is 200mm, and the spacing between two adjacent tie bars 43 is 1200mm. The horizontal bars 41 and longitudinal bars 42 are all made of Φ6 steel bars, and the tie bars 43 are made of Φ8 steel bars. The fixing angle steel 5 is an L100×5 equilateral angle steel, which is arranged along the entire length of the existing wall 1 during installation. A through hole for connecting to the through bolt 6 is opened on one side of the fixing angle steel 5, and the fixing angle steel 5 is welded and fixed to the top of the longitudinal reinforcement 42, serving as a fixing point for the top of the reinforcing steel 4 on the existing wall 1. This avoids the need to implant a large number of reinforcing bars into the existing ring beam 2 and existing roof slab 3, reducing the damage caused. Simultaneously, it provides a firm fixing point for each longitudinal reinforcement 42, enhancing the overall stability of the newly added reinforcement structure in the existing wall 1. The through bolt 6 is a φ12 tie bolt, with nuts 7 at both ends for fixing the fixing angle steel 5. The inner diameter of the nuts 7 matches that of the tie bolts.

[0018] Furthermore, the technical solution also includes cement mortar 8, which is M10 cement mortar, sprayed onto the surface of the existing wall 1 by a spraying machine, with a spraying thickness of 35mm.

[0019] The working principle of this reinforced steel structure is as follows: First, the reinforcement steel 4 is constructed on the existing wall 1. The reinforcement steel 4 is an additional reinforcement for the existing wall 1. The φ6 horizontal bars 41 and longitudinal bars 42 are arranged in two directions along the horizontal and vertical directions, with a spacing of 200mm. At the same time, φ8 tie bars 43 are set with a spacing of 1200mm to reinforce the wall and enhance the shear resistance and integrity of the wall.

[0020] The next step is to install the fixed angle steel 5. The fixed angle steel 5 is an L100×5 equilateral angle steel, which is fixed at the inside corner of the ring beam and the top plate. During installation, it is arranged along the entire length of the existing wall 1.

[0021] The next step is to install the through bolts 6, which are φ12 tie bolts. Drill holes D=25mm in the fixed angle steel 5 and the ring beam, and then pass the through bolts 6 through them. The spacing of the through bolts 6 along the wall direction is 1200mm.

[0022] The next step is to install nut 7, which has an inner diameter of 12mm and is used to fix the through bolt 6 and the angle steel.

[0023] The next step is to fix the top of the longitudinal reinforcement 42 of the existing wall 1, and weld the top of the longitudinal reinforcement to the fixed angle steel 5.

[0024] The next step is to apply cement mortar 8, which is M10 cement mortar. It is sprayed onto the surface of the existing wall 1 using a spraying machine, with a spray thickness of 35mm, to reinforce the existing wall 1.

[0025] Therefore, this utility model uses fixed angle steel to fix the two sides of the existing ring beam as fixing points for the top of the wall reinforcement bars, which can avoid the need to implant a large number of steel bars into the ring beam and top slab, reducing the damage caused to them. At the same time, it ensures that each longitudinal bar has a firm fixing point, enhancing the overall stability of the newly added reinforcement structure in the existing wall. Moreover, this utility model has high construction efficiency, fast speed, small workload, and is simple and quick to implement.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to the technical solution of this utility model, and these modifications or equivalent substitutions cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of this utility model.
