[0031] The following is combined with Figures 1-2 This application is described in further detail.
[0032] The embodiment of the present application discloses a load-bearing beam reinforcement structure for an old building.
[0033] Reference Figure 1 、 2 A load-bearing beam reinforcement structure for an old building includes an old crossbeam 100. Old beam columns 1 with their bottoms removed are respectively provided at both ends of the bottom of the old crossbeam 100. The old beam column 1 is vertically arranged at the bottom of the old crossbeam 100. A reinforcement beam column 2 is provided at the bottom of the old crossbeam 100 and located outside the old beam column 1. The reinforcement beam column 2 is formed by pouring reinforced concrete and wraps the old beam column 1 therein. The old crossbeam 100 is initially reinforced and supported by the reinforcement beam column 2.
[0034] In order to achieve the overall reinforcement of the old beam 100, a reinforcement beam 3 made of cast concrete reinforcement is arranged between the bottom of the old beam 100 and the reinforcement beam columns 2 at both ends of the bottom, and the reinforcement beam 3 is further reinforced by using a transverse reinforcement 4, a first longitudinal reinforcement 5 and a second longitudinal reinforcement 6 by a steel bonding method;
[0035] During the actual reinforcement process, reinforced beams 2 and reinforced crossbeams 3 are set up, and the reinforced beams 2 are used to re-wrap and support the original old beams 1 to increase the structural stability of the old beams 1. The reinforced crossbeams 3 are used to share the load of the original old crossbeams 100 to increase the stability of the structure of the old crossbeams 100, thereby improving the bearing capacity of the old crossbeams 100, and a transverse reinforcement 4, a first longitudinal reinforcement 5 and a second longitudinal reinforcement 6 are set on the reinforced crossbeams 3 to further increase the bearing capacity of the reinforced crossbeams 3.
[0036] refer to Figure 1 、 2 Specifically, in this embodiment, the transverse reinforcement members 4 are respectively arranged on the front and rear opposite sides of the reinforcement beam 3 along the height direction of the reinforcement beam 3, and the first longitudinal reinforcement member 5 and the second longitudinal reinforcement member 6 are respectively arranged on the front and rear opposite sides of the reinforcement beam 3 along the length direction of the reinforcement beam 3, and the transverse reinforcement member 4 is fixedly connected to the first longitudinal reinforcement member 5 and the second longitudinal reinforcement member 6;
[0037] Specifically, the transverse reinforcement member 4 includes a plurality of transverse adhesive steel bars 41, which are spaced apart from each other in the height direction of the reinforcement beam 3. The length of the transverse adhesive steel bars 41 is consistent with the length of the reinforcement beam 3, so as to provide a better reinforcement effect for the reinforcement beam 3.
[0038] The first longitudinal reinforcement member 5 comprises a plurality of first longitudinal adhesive steel bars 51, which are spaced apart from each other in the longitudinal direction of the reinforcement beam 3 and arranged in the middle thereof;
[0039] The second longitudinal reinforcement 6 includes two groups of second longitudinal adhesive steel bars 61, which are respectively located on both sides of the first longitudinal adhesive steel bars 51 at the head and tail ends of the multiple first longitudinal adhesive steel bars 51. Each group of second adhesive steel bars has multiple second adhesive steel bars, and the multiple second adhesive steel bars are arranged at intervals from each other in the length direction of the reinforcing beam 3. The multiple transverse adhesive steel bars 41 and the multiple first longitudinal adhesive steel bars 51 and the multiple second longitudinal adhesive steel bars 61 are arranged perpendicular to each other and are fixed by welding. In this embodiment, the number of transverse steel bars is two, and the number of first longitudinal adhesive steel bars 51 and the second longitudinal adhesive steel bars 61 is six. In other embodiments, the number of bars can be replaced according to the actual situation on site.
[0040] In addition, the spacing between the plurality of second longitudinal adhesive steel bars 61 is smaller than the spacing between the plurality of first longitudinal adhesive steel bars 51. In the actual reinforcement process, the middle portion of the reinforced cross beam 3 is often a plastic zone, which is greatly affected by bending moment and shear force. Therefore, it is necessary to increase the spacing of the first longitudinal adhesive steel bars 51 to adapt to the deformation of the beam and better resist stress concentration in the middle portion. The ends of the reinforced cross beam 3 are often brittle zones, where the stress is relatively small. Therefore, the spacing between the plurality of second longitudinal adhesive steel bars 61 is smaller.
[0041] During the actual reinforcement process, multiple transverse bonded steel bars 41, multiple first longitudinal bonded steel bars 51 and multiple second longitudinal bonded steel bars 61 are set up. The multiple transverse bonded steel bars 41 in the bonded steel plate method are used to improve the bending and shearing capabilities of the reinforced beam 3 in the horizontal direction. The multiple first longitudinal bonded steel bars 51 and the second longitudinal bonded steel bars 61 in the bonded steel plate method are used to improve the bending and shearing capabilities of the reinforced beam 3 in the vertical direction, thereby improving its bearing capacity. In addition, the construction process of the bonded steel plate method is relatively simple and does not require complex equipment and technology, thereby improving construction efficiency.
[0042] refer to Figure 1 、 2Specifically, in this embodiment, reinforcement top plates 7 are respectively provided on both sides of the top of the old beam 100. The reinforcement top plate 7 is fixed to the old beam 100 by multiple first reinforcement members 71. Multiple first reinforcement members 71 are arranged at intervals along the length direction of the reinforcement top plate 7. The first reinforcement member 71 includes a nut, a threaded rod and a barb arranged in sequence from top to bottom. Workers fix it by driving the threaded rod with a barb from the reinforcement top plate 7 into the old beam 100.
[0043] During the actual reinforcement process, a reinforcement top plate 7 is set up, and the reinforcement top plate 7 is used to increase the section modulus of the top of the old beam 100, thereby improving the bearing capacity and bending resistance of the old beam 100, more reasonably distributing the internal force of the old beam 100, improving the stress condition of the old beam 100, and improving the reliability of the node, so that the structural stability of the old beam 100 during the transformation process is higher and safer.
[0044] refer to Figure 1 、 2 Specifically, in this embodiment, angle steels 8 are installed on both sides of the top of the old beam column 1. The top of the angle steels 8 is connected to the bottom of the old crossbeam 100. The angle steels 8 are connected to the old beam column 1 via second reinforcement members 81, which are fixed with bolts. During the actual reinforcement process, the angle steels 8 are installed to increase the section modulus between the old beam column 1 and the old crossbeam 100, thereby improving their load-bearing capacity and bending resistance.
[0045] refer to Figure 1 、 2 Specifically, in this embodiment, a triangular haunch beam 9 is installed at the top of the reinforced beam 2, near the reinforced crossbeam 3. The top of the haunch beam 9 is connected to the bottom of the old crossbeam 100. The side of the haunch beam 9 near the reinforced beam 2 is connected to the reinforced beam 2 via a third reinforcement member 91, which is also secured with bolts. During the actual reinforcement process, the haunch beam 9 is installed to diagonally raise the base of the reinforced beam 2 to support the load-bearing capacity of the reinforced beam 2, improve the stress condition of the reinforced beam 2, and enhance the reliability of the joint.
[0046] The implementation principle of the load-bearing beam reinforcement structure of an old house building in an embodiment of the present application is: setting a reinforced beam column 2 and a reinforced cross beam 3, using the reinforced beam column 2 to re-wrap and support the original old beam column 1, thereby increasing the structural stability of the old beam column 1, using the reinforced cross beam 3 to share the load of the original old cross beam 100, increasing the stability of the structure of the old cross beam 100, thereby improving the bearing capacity of the old cross beam 100, and setting a transverse reinforcement 4, a first longitudinal reinforcement 5 and a second longitudinal reinforcement 6 on the reinforced cross beam 3, and using a transverse adhesive steel bar 41, a first longitudinal adhesive steel bar 51 and a second longitudinal adhesive steel bar 61 to use a steel bonding method to further increase the bearing capacity of the reinforced cross beam 3.
