[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] The following is a further detailed description of embodiments of a tower column partition auxiliary bracket, a bridge pier and a bridge according to the utility model in conjunction with the accompanying drawings.

[0030] First, as Figure 1 and Figure 2 As shown, the present application provides a tower column partition auxiliary bracket, including two sets of embedded steel groups 1, permanent support plates 2 and two hanging molds 3. The permanent support plates 2 and the hanging molds 3 are fixed by the embedded steel groups 1 to form a bottom template for pouring the tower column partition 5, thereby facilitating the construction of the tower column partition 5.

[0031] Specifically, two groups of embedded steel sections 1 are used to be symmetrically arranged on two tower columns 4, each group of the embedded steel sections 1 includes a plurality of embedded steel sections 11 spaced apart along the longitudinal bridge direction, and the connecting ends of all the embedded steel sections 11 of each group of embedded steel sections 1 are used to be connected to the tower column 4, and the supporting ends extend in a direction away from the tower column 4 to form a supporting surface; the two ends of the permanent support plate 2 are respectively placed on the supporting surfaces of the two groups of the embedded steel sections 1 and spaced apart from the tower column 4; two hanging molds 3 are respectively arranged corresponding to the two groups of the embedded steel sections 1 and are located below the permanent support plate 2, one end of the hanging mold 3 is connected to the permanent support plate 2, and the other end extends downward and is used to be connected to the tower column 4, and the two hanging molds 3 and the permanent support plate 2 form a bottom mold for casting the tower column partition 5. It can be understood that the two groups of embedded steel groups 1 are embedded in the tower columns 4 when the two tower columns 4 are constructed. After the construction of the two tower columns 4 is completed, the tower column partition 5 can be constructed, thereby realizing asynchronous construction of the tower column partition and the tower column, thereby improving construction efficiency.

[0032] Since the embedded steel 11 is embedded in the tower column 4, it has good structural stability. At the same time, the embedded steel 11 becomes a part of the structure of the tower column partition 5 after the tower column partition 5 is poured, so that the connection between the tower column partition 5 and the tower column 4 is more stable. By locating the hanging formwork 3 below the permanent support plate 2 and connecting it with the permanent support plate 2 at an angle, after pouring concrete, the concrete is poured on the permanent support plate 2 and poured onto the hanging formwork 3 through the gap between adjacent embedded steel 11, forming a trapezoidal chamfer at the connection between the tower column partition 5 and the tower column 4, so as to increase the connection area between the tower column partition 5 and the tower column 4 and improve the connection stability.

[0033] It should be noted that the length of the permanent support plate 2 should be less than the spacing distance between the two tower columns 4, that is, after the permanent support plate 2 is placed on the two groups of embedded steel groups 1, its two ends will not abut against the two tower columns 4, so that concrete can be poured onto the hanging formwork 3 through the embedded steel groups 11.

[0034] In some optional embodiments, the embedded steel 11 is arranged horizontally.

[0035] It can be understood that the embedded steel 11 supports the permanent support plate 2, and concrete is poured on the permanent support plate 2 to form a whole with the permanent support plate 2. Therefore, the embedded steel 11 should have sufficient supporting force and is preferably perpendicular to the tower column 4 and horizontally arranged so that the top surfaces of the two groups of embedded steel groups 1 form a horizontal supporting surface for supporting the permanent support plate 2.

[0036] In some optional embodiments, the permanent support plate 2 is a precast concrete plate.

[0037] In order to reduce construction time and improve construction efficiency, the permanent support plate 2 is prefabricated in advance according to the design requirements of the tower column partition plate 5.

[0038] In some optional embodiments, one end of the hanging formwork 3 is detachably connected to the bottom wall of the permanent support plate 2 , and the other end is used for detachably connecting to the tower column 4 .

[0039] The purpose of such arrangement is to make the hanging formwork 3 integral with the permanent support plate 2 for the convenience of concrete pouring. And the hanging formwork 3 needs to be removed after the concrete pouring of the tower column partition 5 is completed, so it is arranged to be detachably connected.

[0040] In some optional embodiments, all the embedded steel sections 11 of the embedded steel section group 1 are arranged at equal intervals so that each embedded steel section 11 is subjected to uniform force, thereby improving the connection stability of the tower column partition 5.

[0041] In some optional embodiments, the inner wall of the hanging mold 3 is aligned with the outer edge of the end of the permanent support plate 2 .

[0042] It can be understood that such an arrangement allows the tower column partition 5 to have a smooth outer contour after casting, and avoids the problem of voids due to incomplete concrete casting during the casting process caused by the angle formed between the hanging formwork 3 and the bottom wall of the permanent support plate 2.

[0043] On the second aspect, the present application also provides a bridge pier, which is constructed using any of the above-mentioned auxiliary brackets, and includes two tower columns 4, two groups of embedded steel groups 1 and a tower column partition 5, wherein part of the embedded steel group 1 is connected to the tower column 4, and part is connected to the tower column partition 5, so that the tower column partition 5 is stably connected to the tower column 4.

[0044] Specifically, two tower columns 4 are arranged at intervals; two groups of embedded steel sections 1 are symmetrically arranged on the two tower columns 4, each group of the embedded steel sections 1 includes a plurality of embedded steel sections 11 arranged at intervals along the longitudinal bridge direction, and the connecting ends of all the embedded steel sections 11 of each group of embedded steel sections 1 are used to connect with the tower column 4, and the supporting ends extend in the direction away from the tower column 4 to form a supporting surface; the tower column partition 5 includes a permanent support plate 2 and a cast partition body 51, the two ends of the permanent support plate 2 are respectively placed on the supporting surfaces of the two groups of embedded steel sections 1, and the cast partition body 51 is cast on the permanent support plate 2.

[0045] It can be understood that the permanent support plate 2 and the casting partition body 51 are integrally formed after casting is completed, and the two tower columns 4 are connected by the tower column partition 5.

[0046] During construction, the tower column 4 is constructed first, and when the tower column 4 is constructed, two groups of embedded steel groups 1 are respectively embedded in the two tower columns 4, and the positions of the two groups of embedded steel groups 1 correspond to each other; then after the construction of the tower column 4 is completed, the hanging formwork 3 and the permanent support plate 2 can be installed, and concrete is poured to form a cast partition body 51, and form a whole with the permanent support plate 2. After the pouring is completed, wait for the concrete to solidify and remove the hanging formwork 3.

[0047] In some optional embodiments, the embedded steel 11 is arranged horizontally.

[0048] In some optional embodiments, the permanent support plate 2 is a precast concrete plate.

[0049] In a third aspect, the present application also provides a bridge, comprising any of the above-mentioned bridge piers.

[0050] The utility model provides a tower column partition auxiliary bracket, bridge pier and bridge, by pre-embedding the embedded steel 11 during the construction of the tower column 4, and then constructing the tower column partition 5 by using the embedded steel 11, hanging formwork 3 and permanent support plate 2 after the construction of the tower column 4 is completed, thereby realizing asynchronous construction of the tower column and the tower column partition, improving construction efficiency and shortening construction time; and the permanent support plate 2 is a precast concrete plate, which is supported and fixed by the embedded steel 11, and forms a bottom template for pouring the partition body 51 with the hanging formwork 3, thereby facilitating the construction of the tower column partition 5.
