Description

Technical Field

[0001] The utility model relates to the technical field of building structure reinforcement, in particular to a reinforcement structure for strengthening a beam bottom masonry body subjected to insufficient local compression. Background Art

[0002] For old existing masonry structures, due to the long construction period, inadequate design and construction measures have led to the lack of beam pads at the bottom of the beams in masonry structures without ring beams. This results in the floor load being transferred to the beams, and then to the masonry walls. The masonry at the bottom of the beams is locally compressed and cannot meet the local bearing capacity. In this case, it is difficult to implement reinforcement by adding beam pads. Summary of the Invention

[0003] The utility model aims to provide a reinforcement structure for strengthening the masonry at the bottom of a beam when the masonry is locally under-compressed, so as to solve the problem of reinforcing both sides of the masonry at the bottom of a beam when the masonry is locally under-compressed.

[0004] To achieve the above-mentioned purpose, the utility model provides a reinforcement structure for strengthening the local under-compression masonry at the bottom of a beam, comprising: a reinforcement surface layer, the reinforcement surface layer being arranged on the front and rear sides of the masonry at the bottom of a concrete beam; beam bottom through-wall steel bars, two groups of beam bottom through-wall steel bars being symmetrically arranged below the bottom of the concrete beam, the front and rear ends of the beam bottom through-wall steel bars vertically passing through the masonry; beam side through-wall steel bars, multiple groups of beam side through-wall steel bars being symmetrically arranged on the left and right sides of the concrete beam, the front and rear ends of the beam side through-wall steel bars vertically passing through the masonry; reinforcement bent steel bars, two groups of reinforcement bent steel bars being symmetrically arranged on the front and rear sides of the masonry, each group of reinforcement bent steel bars being provided with multiple reinforcement bent steel bars, the multiple reinforcement bent steel bars being passed between the beam bottom through-wall steel bars and the beam side through-wall steel bars, and being fixedly connected to the bottom of the beam bottom through-wall steel bars and the top of the beam side through-wall steel bars, respectively, to form a reinforcement skeleton structure.

[0006] In a preferred embodiment, the left and right sides of the first horizontal portion are respectively 50 mm larger than the width of the concrete beam, the first horizontal portion is 50 mm away from the bottom of the beam, and the second horizontal portion is 50 mm away from the floor panel or roof panel.

[0007] In a preferred embodiment, the distance between the first horizontal portion and the second horizontal portion of two adjacent reinforced bent steel bars is 100 mm respectively.

[0008] In a preferred embodiment, four groups of beam-side through-wall steel bars are provided, of which two groups of beam-side through-wall steel bars are spaced apart on the left side of the concrete beam, and the other two groups of beam-side through-wall steel bars are spaced apart on the right side of the concrete beam.

When only the local compression part of the wall is reinforced, the reinforced surface layer is a high-toughness concrete surface layer with a thickness of not less than 35 mm, and the outer side surface of the reinforced surface layer exceeds the outer contour of the reinforced bent steel bars.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention symmetrically arranges multiple reinforcing bent steel bars on the front and rear sides of the masonry at the bottom of the beam, and the multiple reinforcing bent steel bars are passed between the beam bottom through-wall steel bars and the beam side through-wall steel bars, and are respectively fixedly connected to the bottom of the beam bottom through-wall steel bars and the top of the beam side through-wall steel bars to form an effective steel skeleton structure, which is reinforced by pulling up and down to ensure the reinforcement effect, and solves the problem that the local compressive bearing capacity of the masonry without beam pads at the bottom of the beam is not satisfied and it is difficult to effectively increase the beam pad reinforcement treatment.

[0017] The technical solutions in the embodiments of the present invention are described clearly and completely below. The embodiments of the present invention and all other embodiments obtained by persons of ordinary skill in the art without creative work are within the scope of protection of the present invention.

[0018] Example 1:

[0019] like Figures 1 to 4 As shown, the reinforcement structure for the masonry at the bottom of the beam in this embodiment, which is locally under-compressed and reinforced, comprises: a reinforcement surface layer 2, masonry 3, beam bottom through-wall steel bars 4, beam side through-wall steel bars 5, and reinforcement bent steel bars 6. The reinforcement surface layer 2 is arranged on the front and rear sides of the masonry 3 at the bottom of the concrete beam 1 where the masonry 3 is locally under-compressed. Two groups of beam bottom through-wall steel bars 4 are symmetrically arranged below the bottom of the concrete beam 1. The front and rear ends of the beam bottom through-wall steel bars 4 pass vertically through the masonry 3 and are respectively arranged in the reinforcement surface layer 2 at the front and rear sides. Multiple groups of beam side through-wall steel bars 5 are symmetrically arranged on the left and right sides of the concrete beam 1. The front and rear ends of the beam side through-wall steel bars 5 pass vertically through the masonry 3 and are respectively arranged in the reinforcement surface layer 2 at the front and rear sides. Two groups of reinforcing bent steel bars 6 are symmetrically arranged on the front and rear sides of the masonry 3. Each group of reinforcing bent steel bars 6 is provided with multiple reinforcing bent steel bars. The multiple reinforcing bent steel bars 6 are passed between the bottom through-wall steel bars 4 of the beam and the side through-wall steel bars 5 of the beam, and are fixedly connected to the bottom of the bottom through-wall steel bars 4 of the beam and the top of the side through-wall steel bars 5 of the beam respectively to form an effective steel skeleton structure, and "hold" the concrete beam 1 by pulling up and down, so as to "reduce the burden" on the masonry at the bottom of the beam that is not under pressure, thereby ensuring the reinforcement effect and the reliability of the reinforcement steel bar connection.

[0020] Furthermore, two groups of reinforcing bent steel bars 6 are symmetrically arranged in the reinforcing surface layer 2 on the front and rear sides of the masonry 3, and the reinforcing bent steel bars 6 include a first horizontal portion 61, a second horizontal portion 62 and an inclined connection portion 63, wherein the first horizontal portion 61 is arranged parallel to the bottom of the beam, and the two ends of the first horizontal portion 61 are respectively welded to the bottom of the beam bottom through-wall steel bars 4, and the second horizontal portion 62 is symmetrically arranged on both sides of the first horizontal portion 61, and the second horizontal portion 62 is welded to the top of the beam side through-wall steel bars 5, and the height of the second horizontal portion 62 is higher than the first horizontal portion 61, and the first horizontal portion 61 and the second horizontal portion 62 are connected by the inclined connection portion 63.

[0021] Example 2:

[0022] In one specific embodiment, based on Example 1, the diameter of the reinforcing bent steel bar 6 is 10 mm. The left and right sides of the first horizontal portion 61 are each 50 mm greater than the width of the concrete beam 1. The first horizontal portion 61 is 50 mm from the bottom of the beam, and the second horizontal portion 62 is 50 mm from the floor or roof panel 7, which is typically a prefabricated panel. The distance between the first and second horizontal portions 61, 62 of two adjacent reinforcing bent steel bars 6 is 100 mm, respectively.

[0023] Furthermore, the beam bottom through-wall steel bars 4 and the beam side through-wall steel bars 5 are both large-diameter drilled through-wall steel bars with a diameter of 20 mm. There are four groups of beam side through-wall steel bars 5, two of which are arranged at intervals on the left side of the concrete beam 1, and the other two groups of beam side through-wall steel bars 5 are arranged at intervals on the right side of the concrete beam 1. Each group of beam side through-wall steel bars 5 has three evenly spaced steel bars in the vertical direction, each group of beam bottom through-wall steel bars 4 has three evenly spaced steel bars in the vertical direction, and each group of reinforcing bent steel bars 6 has three.

[0024] Furthermore, if the masonry 3 is a wall, and only the locally compressed areas of the wall are reinforced without reinforcement, the reinforced surface layer 2 is a high-toughness concrete surface layer with a thickness of not less than 35 mm, and the outer surface of the reinforced surface layer 2 exceeds the outer contour of the reinforcing bent steel bars 6. If the wall is reinforced as a whole, the reinforced surface layer 2 is the surface layer of the wall reinforcement, such as a reinforced concrete slab wall or a steel mesh cement mortar surface layer.
