Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a temporary locking device for pier top rotation operation. Background Art

[0002] With the rapid development of my country's transportation infrastructure, there are more and more cases of new bridges crossing existing railways, highways, etc. In order to reduce or eliminate the impact on existing lines and ensure that the project can be completed in a high-quality, safe and fast manner, the swivel bridge solution has been increasingly used. The emergence of new ball-jointed swivels enables the swivel operation to be carried out smoothly and efficiently. After the swivel operation is completed, in order to ensure the smooth completion of the subsequent closing section, the conventional temporary locking method uses steel wedges made of thick steel plates. As a temporary locking device, it still has the following disadvantages:

[0003] 1. Temporary locking operation is not convenient

[0004] Steel wedges are selected as temporary locking devices. When the space between the support foot and the pier top is selected as the placement position of the temporary locking device, it will be compressed by the pressure of the beam body at a later time, so it is difficult to remove. Forced removal will damage the support foot.

[0005] 2. Temporary locking cannot provide vertical pulling force

[0006] When steel wedges are selected to lock between the support feet and the pier top, they can only play a supporting role and cannot provide vertical tension. The temporary locking is unstable and affects the linear shape of the beam during the construction of the closing section. Utility Model Content

When in use, the temporary locking device and the steel plate at the bottom of the beam are fixedly connected by bolts by bolt connection, and after the beam body is rotated into place, the fine rolled threaded steel bar is connected to the temporary locking device, and the temporary locking device should be installed at the corresponding positions on the front and rear sides of the beam body when installing the temporary locking device, and the four groups of temporary locking devices are installed at the same time to fix the beam body and the pier body to achieve the effect of temporary locking, which is used to prevent the beam body from shaking during the later construction process and ensure the safety of construction, and at the same time assist the ball joint to support the beam body.

[0027] It should be noted that temporary locking is to ensure that the beam does not deflect or sway left and right during the closing section construction process after the beam is rotated into place, further ensuring construction safety. The temporary locking device of this application utilizes the larger space between the bottom of the beam and the top of the pier. It is easy to install and disassemble, can effectively lock the beam, and can ensure the integrity of the ball joint system, which is of great significance to the promotion of the pier top rotation process.

The vertical support member 20, the transverse support member 10 and the longitudinal support member 30 are all I-beams, which can ensure the support strength of the support frame and are convenient to obtain. In other embodiments, the vertical support member 20, the transverse support member 10 and the longitudinal support member 30 can also be square tubes. The use of I-beams in the present application has a better effect. Specifically, the transverse support member 10 is provided at both ends of the vertical support member 20 in the same number, and the longitudinal support member 30 is provided at both ends of the vertical support member 20 in the same number, that is, the transverse support member 10 and the longitudinal support member 30 are provided at both ends of the support frame in two, and the support plate 40 is welded and fixed to the support frame. In this way, the installation stability of the support plate 40 on the support frame can be ensured. Specifically, the support plate 40 is a steel plate. The use of steel plates can ensure the stability of the connection with each other and have sufficient support strength. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
