[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0027] A high pier hanger suitable for cast-in-place beam construction, such as Figures 1 to 4As shown, it includes a high pier body and a hanger body arranged on the high pier body, the hanger body includes an upper longitudinal beam 2, a hanger rod 4 and a bottom longitudinal beam 6, at least three upper longitudinal beams 2 are arranged at intervals, and two adjacent upper longitudinal beams 2 are connected by a support beam 3; two hangers 4 are arranged at the left and right ends of each upper longitudinal beam 2, and there is a matching gap between the hangers 4 at the left and right ends of each upper longitudinal beam 2 and the high pier body, the length direction of the hanger rod 4 is perpendicular to the length direction of the upper longitudinal beam 2, and one end of the hanger rod 4 is connected to the upper longitudinal beam 2 , the other end is connected to the bottom longitudinal beam 6, and the two adjacent hangers 4 are connected by an upper connecting piece 5; the bottom longitudinal beam 6 is arranged in a one-to-one correspondence with the upper longitudinal beam 2, and the two are parallel to each other. The two adjacent bottom longitudinal beams 6 are connected by a lower connecting piece 7, and each of the bottom longitudinal beams 6 is provided with a limit block 8 for supporting the high pier body at one end facing the high pier body; the outermost bottom longitudinal beam 6 of the hanger body is provided with a diagonal rod 9 at one end different from the high pier body, and one end of the diagonal rod 9 is connected to the bottom longitudinal beam 6, and the other end is connected to the outermost hanger 4 of the hanger body.

[0028] For example, the support beam 3 and the upper longitudinal beam 2, the upper longitudinal beam 2 and the hanger rod 4, the hanger rod 4 and the bottom longitudinal beam 6, and the limit block 8 and the bottom longitudinal beam 6 can all be connected by welding. After the above components are welded, they can form a hanger body. The hanger body has a receiving groove (i.e., a matching gap) in the middle portion that matches the top of the high pier body, and bosses for connecting to the Bailey beam at the left and right ends of the hanger body. In addition, those skilled in the art can also select other connection methods according to actual needs to achieve a stable connection between the upper longitudinal beam 2 and the hanger rod 4, and between the hanger rod 4 and the bottom longitudinal beam 6, to ensure the overall structural strength and stability of the hanger body. This will not be repeated here.

[0029] Preferably, the upper connecting member 5 is arranged on the side of the hanger 4 facing the high pier body. By arranging the upper connecting member 5 on the side of the hanger 4 facing the high pier body, it is possible to prevent the connecting member from affecting the load-bearing of the hanger body on the Bailey beam, while also improving the structural strength and stability of the hanger 4, ensuring that the hanger 4 can continuously and stably limit the bottom longitudinal beam 6.

[0030] In actual application, at least two upper connectors 5 are provided at intervals along the length direction of the hanger 4, and upper connectors 5 are provided on the hanger 4 corresponding to the connection between the hanger 4 and the upper longitudinal beam 2, and the connection between the hanger 4 and the bottom longitudinal beam 6. One end of the upper connector 5 is connected to the hanger 4, and the other end is connected to the upper longitudinal beam 2 or the bottom longitudinal beam 6. Exemplarily, the upper connector 5 and the hanger 4, the upper longitudinal beam 2, and the bottom longitudinal beam 6 can be connected by welding. Those skilled in the art can also choose other connection methods according to actual needs, which will not be repeated here. In addition, two upper connectors 5 can be provided corresponding to the connection between the hanger 4 and the bottom longitudinal beam 6, or multiple upper connectors can be provided, and two of them can be provided corresponding to the connection between the hanger 4 and the upper longitudinal beam 2, and the connection between the hanger 4 and the bottom longitudinal beam 6, respectively. Those skilled in the art can make settings according to actual needs, which will not be repeated here.

[0031] By providing multiple upper connectors 5, the multiple upper connectors 5 can better strengthen the structure of the hanger rod 4, thereby improving the structural strength and stability of the lower half of the hanger body. At the same time, by using the upper connectors 5 to connect to the upper longitudinal beam 2 or the bottom longitudinal beam 6, the upper connectors 5 can also strengthen the structural strength of the connection between the hanger rod 4 and the upper longitudinal beam 2, and the hanger rod 4 and the bottom longitudinal beam 6.

[0032] Preferably, the lower connector 7 is disposed below the bottom longitudinal beam 6, with at least two lower connectors 7 spaced apart along the length of the bottom longitudinal beam 6. For example, two, three, or more lower connectors 7 may be spaced apart, and each lower connector 7 may be welded to the bottom longitudinal beam 6. Those skilled in the art may also choose other connection methods based on actual needs, which will not be described here. Providing multiple lower connectors 7 can also enhance the structural strength of the bottom longitudinal beam 6.

[0033] In actual use, the diagonal brace 9, upper connector 5, and lower connector 7 are all made of channel steel. For example, one end of the diagonal brace 9 is welded to the bottom longitudinal beam 6, and the other end is welded to the hanger 4. Those skilled in the art may also choose other methods to install the diagonal brace 9 according to actual needs. Diagonal braces 9 are installed on the outside of the left and right ends of the hanger body, with two diagonal braces 9 provided on the front and rear sides of each end of the hanger body. A gap exists between the two diagonal braces 9 to accommodate the Bailey beam. The two diagonal braces 9, the bottom longitudinal beam 6, and the hanger 4 form a boss for connecting the Bailey beam.

[0034] By setting the diagonal tie rods 9, it is not only beneficial to disperse the force on the bottom longitudinal beam 6, but also to improve the structural strength of the connection between the bottom longitudinal beam 6 and the hanger 4, ensuring that the bosses at the left and right ends of the hanger body can continuously and stably support the Bailey beam; and the two diagonal tie rods 9 can also play a good limiting role on the side of the Bailey beam, which is beneficial to prevent the Bailey beam from separating from the hanger body.

[0035] Preferably, the middle portions of the suspenders 4 are connected by connecting beams 10, and two adjacent connecting beams 10 are arranged in a V-shape. For example, the connecting beams 10 and the suspenders 4 can also be connected by welding. By arranging the connecting beams 10 in the middle of the suspenders 4, the installation of the Bailey beam will not be affected. At the same time, the connecting beams 10 arranged in a V-shape can also form a supporting structure to provide good support for each suspender 4. In conjunction with the upper connector 5, it is beneficial to further improve the connection strength between the suspenders 4 and ensure the stability of the suspenders 4.

[0036] Preferably, an embedded plate 1 is provided on the high pier body at a position corresponding to the upper longitudinal beam 2, and the upper longitudinal beams 2 are connected to the embedded plate 1. For example, the embedded plate 1 can be an embedded steel plate, which can be embedded and fixed on the high pier body, and the upper longitudinal beams 2 can be welded and fixed to the embedded plate 1. Those skilled in the art can also choose other methods according to actual needs to achieve a stable connection between the upper longitudinal beams 2 and the embedded plate 1, which will not be described in detail here.

[0037] In actual construction, when it's difficult to create a bracket with embedded reinforcement, Xu converted the bracket into a hanger, leveraging the strong compressive strength of concrete to allow the pier top concrete to bear the vertical pressure. Therefore, this embodiment installs an embedded steel plate at the top of the high pier body and welds the upper longitudinal beam 2 to the embedded steel plate, allowing the weld to bear the tensile force of the hanger body. Simultaneously, the bottom of the hanger body cooperates with the limiting groove on the high pier body through the limiting block 8 on the bottom longitudinal beam 6 to ensure the deformation requirements of the hanger body bottom, improve the stability of the hanger body on the high pier body, and ensure subsequent construction. Furthermore, after construction is completed, the pier top concrete reserved by the embedded plate 1 can be poured later, resulting in a novel structure that is safe and reliable.

[0038] Preferably, the upper longitudinal beam 2, the hanger 4 and the bottom longitudinal beam 6 are all made of double-jointed I-beams. Compared with other structures, double-jointed I-beams have higher structural strength and are relatively light in weight, making them easy to construct.

[0039] Preferably, the high pier body is provided with a limiting groove that cooperates with the limiting block 8. The cooperation between the limiting block 8 and the limiting groove is beneficial to further improve the stability of the hanger body on the high pier body.

[0040] During the construction of the pier top of the high pier body, taking into account the construction of the later supports, an embedded plate 1 is set at a certain position on the pier top, and three double-jointed I-beams are welded on the embedded plate 1 as the upper longitudinal beam 2 (fully welded). Three hangers 4 are butt-jointed on each side of the beam, and the hangers 4 are welded together with upper connectors 5. A bottom longitudinal beam 6 is set at the bottom of the hanger 4, and a limit block 8 is fixed on the bottom longitudinal beam 6. A diagonal brace 9 is set on the outermost side of the bottom longitudinal beam 6 and the vertical hangers 4 to increase the rigidity of the hanger in the direction of the bridge. The net distance between the hanger 4 and the pier top is about 20 cm, and butt-fusion welding is adopted between the hanger 4 and the upper longitudinal beam 2, as well as between the hanger 4 and the bottom longitudinal beam 6. Steel sections can be placed on the bottom longitudinal beam 6 as Bailey beam supports. After the construction of the cast-in-place beam is completed, the hanger body can be disassembled by cutting or the main beam can be lifted up with a jack to remove the hanger body.

[0041] The utility model discloses a high pier hanger suitable for cast-in-situ beam construction, which has the advantages of simple structure, easy construction, high structural strength and good stability. During the construction of high pier cast-in-situ beams, the hanger is installed on the pier top by utilizing the high compressive strength of concrete, so that the pier top can bear the pressure generated by the deadweight of the beam body. By utilizing the upper longitudinal beam to connect with the embedded plate, the horizontal tension of the upper longitudinal beam can be borne, and the limit block can not only directly reduce the horizontal displacement of the bottom longitudinal beam and the bottom of the hanger, but also transmit the horizontal force from the bottom longitudinal beam to the contacting concrete high pier body through the limit block, thereby reducing the horizontal shear stress at the connection between the upper longitudinal beam and the embedded plate. Therefore, by using this hanger for construction, the construction difficulty can be effectively reduced, the amount of work can be reduced, and it has the advantages of being economical, safe and simple to construct.

[0042] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
