Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, and more specifically, to a support foot for balanced rotation construction. Background Technique

[0002] At present, the bridge horizontal rotation construction schemes include two types: longitudinal inclined rotation and balanced rotation. The longitudinal inclined rotation system is slightly inclined along the longitudinal axis direction during the rotation process, making the rotation system a two-point vertical support system to increase the stability of the rotating structure in the vertical plane. The balanced rotation system remains balanced in the static state, so that the vertical axis of the spherical hinge passes through the center of gravity of the rotation system.

[0003] However, in the balanced rotation construction, the rotation system is easily affected by external factors such as wind, snow, and vibration, resulting in overturning, which affects the stability and safety of the rotation. At the same time, the settlement during the construction of the upper structure of the rotation is uncertain, resulting in the uncertainty of the bottom clearance of the support foot. And after the rotation is in place, if the bottom clearance of the support foot is too small, the range of bridge attitude adjustment is also limited.

[0004] For the problems in the related technology, no effective solution has been proposed yet. Content of the Utility Model

[0026] According to an embodiment of the present invention, a support foot for balanced rotation construction is provided.

[0027] Embodiment 1;

[0028] As Figures 1 - 5 shown, a support foot for balanced rotation construction according to an embodiment of the present invention includes a support foot walking board 1. After the rotation construction is completed, the adjustment steel plate and the following parts can be reused, thereby reducing the material cost. Above the support foot walking board 1, there is a support assembly 2. The support assembly 2 includes a plurality of steel pipes 201 fixedly arranged above the support foot walking board 1. The number of steel pipes 201 is not less than two. Above the steel pipes 201, there is a fixedly connected top plate 202;

[0029] A plurality of vertical plates 203 are welded on the top plate 202, the steel pipes 201 and the support foot walking board 1. In the middle position of the top plate 202, there are several holes 6. The number of holes 6 is five. The size of one hole 6 is larger than that of the other four holes 6, which is used for pouring concrete into the steel pipes 201. Whether to pour the concrete 7 can be determined according to the actual situation during actual use, and the pouring material can be adjusted and replaced according to the actual situation. For example, the pouring material is epoxy grouting material; the top plate 202, the steel pipes 201, the support foot walking board 1 and the vertical plates 203 are welded into a whole;

[0030] Above the support assembly 2, an adjustment assembly 3 is installed. The adjustment assembly 3 includes an adjustment steel plate 301 installed above the top plate 202, which is used to adjust the gap between the top plate 202 and the embedded steel plate 302. Above the adjustment steel plate 301, an embedded steel plate 302 is provided. In actual use, the embedded steel plate 302 can be just a single steel plate, or it can be a steel plate welded to a steel pipe, or a steel plate welded or thread-connected to an anchor bar. Multiple connection holes 303 are opened on the embedded steel plate 302, the adjustment steel plate 301 and the top plate 202. The number of the connection holes 303 is six, and connection bolts 304 are installed on the inner walls of the connection holes 303.

[0031] In actual application, through the mutual cooperation between the support assembly 2 and the adjustment assembly 3 provided on the support foot walking board 1, before the rotation construction, according to the actually measured gap between the support foot and the slideway, the number and thickness of the added adjustment steel plates 301 can be determined, so as to control the range of the bottom gap of the support foot and the adjustment of the bridge attitude during the rotation construction, increasing the safety and reliability of the support foot for the balanced rotation construction and reducing the situation where the range of the bridge attitude adjustment is restricted.

[0032] Embodiment 2;

[0033] As Figures 1 - 5 shown, for a support foot for balanced rotation construction according to an embodiment of the present invention, an anchoring assembly 4 is connected to the adjustment assembly 3. The anchoring assembly 4 includes a sleeve 401 thread-connected to one end of the connection bolt 304. Above the sleeve 401, an anchor rod 402 is provided. An upper turntable 5 is installed on the sleeve 401, the anchor rod 402 and the embedded steel plate 302.

[0034] In actual application, through the anchoring assembly 4 provided on the connection bolt 304, the problem of overturning caused by external factors such as wind, snow, and vibration during the balanced rotation construction is solved, the starting traction force during the rotation construction is reduced, and the risk of easy overturning during the balanced rotation construction can be reduced.

[0035] In order to facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0036] In summary, by means of the above technical solution of the present utility model, during installation, the support foot walking board 1 is placed in the area where it needs to be placed, and then concrete 7 is poured into the steel pipe 201 through the hole 6. After pouring, the connecting bolt 304 passes through the connecting holes 303 opened in the top plate 202, the embedded steel plate 302 and the adjusting steel plate 301, and is threadedly connected to the sleeve 401. Then, by adding the adjusting steel plate 301 between the top plate 202 and the embedded steel plate 302, the clearance at the bottom of the support foot is adjusted. For the solution of installing the adjusting steel plate 301 at the bottom of the support foot walking board 1, the thickness and quantity of the adjusting steel plate 301 are calculated by subtracting the target clearance from the initial state clearance; for the top adjustment, only an adjusting steel plate 301 or a wedge block with the same clearance as required is set at the bottom of the support foot. By loosening and tightening the connecting bolt 304 and placing the adjusting steel plate 301 that fills the clearance between the top plate 202 and the embedded steel plate 302, the support foot clearance can be controlled in advance, and the installation is simple with higher adjustment accuracy. It solves the problem of overturning during the balanced rotation construction due to external factors such as wind, snow, and vibration, reduces the starting traction force during the rotation construction, can reduce the risk of easy overturning during the balanced rotation construction, and improves the feasibility of the balanced rotation construction. At the same time, before the rotation construction, according to the measured clearance between the support foot and the slideway, the quantity and thickness of the added adjusting steel plate 301 are determined, so as to control the clearance at the bottom of the support foot and the range of bridge attitude adjustment during the rotation construction, increase the safety and reliability of the support foot in the balanced rotation construction, reduce the situation where the range of bridge attitude adjustment is restricted. After the rotation construction is completed, it can be removed and reused, thus reducing the material cost. At the same time, during the top adjustment, the worker stands to adjust the support foot clearance; if the adjusting steel plate 301 is set at the bottom, the worker needs to adopt a squatting or lying-down posture for a long time. Compared with the bottom adjustment, the top adjustment is more user-friendly and has higher efficiency.

[0037] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
