Abstract

[0002] Bridge engineering is an indispensable part of high-speed railway construction. The reinforcement of ladder cages is very important in the construction of bridge piers. The traditional method of reinforcing pier ladder cages is to connect them with the pier body using angle steel, which has poor flexibility. This fixing method cannot solve the reinforcement of ladder cages and pier bodies with different spacings. The angle steel can only be re-cut and cannot be reused, resulting in material waste. At the same time, the linear fixed connection method using a single angle steel is not firm, and the connector has poor ability to withstand lateral forces, resulting in poor connection strength and stability.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0019] like Figures 1 to 3 As shown, an adjustable pier body ladder cage wall connection member includes a connecting rod 1, both ends of which are respectively equipped with connecting heads 2 through threads, and the threads between the two corresponding connecting heads 2 are set in reverse.
[0020] When in use, the pier body and the ladder cage are connected through two connecting heads 2 respectively arranged at both ends of the connecting rod 1. The docking position between the connecting head 2 and the connecting rod 1 can be adjusted according to the actual distance between the pier body and the ladder cage, and the overall length between the connecting rod 1 and the connecting head 2 can be further adjusted so that the overall length adapts to the required length of the actual connection position.
[0021] As a specific implementation, the connector 2 includes a threaded rod 21 and a first connecting plate 22 welded to the outer end of the threaded rod 22 (the end of the connector 2 away from the connecting rod 1 is the outer end), and a first bolt hole 221 for bolt fixing is provided on the first connecting plate 22; the connecting rod 1 is a hollow rod, and the cavities at both ends of the connecting rod 1 are provided with threads matching the threaded rod 22. In this way, the connector 2 is connected to the connecting rod 1 through the threaded rod 21, and the connector 2 is connected to the connecting piece corresponding to the pier body or the ladder cage through the first connecting plate 22.
[0022] Furthermore, in order to facilitate the flexible application of the connecting rod 1 during construction, an adjustment handle 3 is provided on the rod body of the connecting rod 1. Preferably, the adjusting handle 3 is provided at both ends of the connecting rod 1, and two adjustment handles 3 are symmetrically provided at each end of the connecting rod 1. The purpose of such a design is that when the pier body and the ladder cage are connected by the connecting rod 1, when the distance between the pier body and the ladder cage is not measured, the connector 2 at one end of the connecting rod 1 can be connected to the pier body first, and then the connecting rod 1 can be rotated by the adjusting handle 3 according to the difference in connection length. Since the threads at both ends of the connecting rod 1 are set in opposite directions, when the connecting rod 1 is rotated in the same direction, the connectors 2 at both ends extend or contract at the same time, thereby adjusting the overall length formed between the connecting rod 1 and the connector 2 until it is adjusted to a suitable connection distance, and then the connector 2 corresponding to the ladder cage can be fixed.
[0023] Of course, the corresponding unfixed connecting head 2 may also be directly rotated to adjust the overall length between the connecting rod 1 and the connecting head 2 .
[0024] As a preferred embodiment, three connecting rods 1 are used, two of which are arranged in parallel for connecting the pier body and the ladder cage, and another connecting rod 1 is connected to the two connecting rods 1 to form a "Z"-shaped structure. In this way, the three connecting rods 1 together form two nearly triangular structures, which increases the connection strength and stability between the pier body and the ladder cage.
[0025] Specifically in this embodiment, a second connecting plate 4 is provided on the rod body of the connecting rod 1. Preferably, a second connecting plate 4 is provided at both ends of the connecting rod 1. The second connecting plate 4 is provided with bolt holes 41 for bolt fixing.
[0026] When in use, two connecting rods 1 used to connect the pier body and the ladder cage and arranged in parallel are adjusted to a suitable connection length, and at the same time, the second connecting plates 4 corresponding to the above two connecting rods 1 are facing inward (the side opposite to the above two connecting rods 1 is the inner side), and then the third connecting rod 1 is used and connected to the second connecting plates 4 corresponding to the above two connecting rods 1 through its corresponding two connecting heads 2.
[0027] It should be noted that, in this embodiment, when the corresponding second connecting plates 4 are connected, two second connecting plates in diagonal directions are connected, so that the three connecting rods 1 after connection are in a "Z"-shaped structure.
[0028] Preferably, in this embodiment, according to the common spacing range between the pier body and the ladder cage, the connecting rod 1 is cut from a steel pipe with a diameter of 70 mm and a wall thickness of 3 mm, and is 200 cm long; the threaded rod 21 is 64 mm in diameter and 60 cm in length.
[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-limiting from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
