Description

Technical Field

[0001] This application relates to the technical field of bridge engineering, and more specifically, to a movable support for bridge construction. Background Technique

[0002] Conventional bridges usually include structures such as pier columns and capping beams. Among them, the capping beam is erected on the pier column. During construction, the pier column is constructed first, and after the construction of the pier column is completed, the construction of the capping beam is carried out.

[0003] In the prior art, currently, a working platform is set up for the construction of conventional pier columns, or a finished climbing ladder is used as the construction platform for Y-shaped pier columns. Due to the different lengths and widths of the pier column and the capping beam, the fixed positions of the pier column support, the capping beam support and the ground are also different. Therefore, after the construction of the pier column is completed, the working platform or the finished climbing ladder needs to be demolished, and after the demolition is completed, the capping beam support needs to be re-erected. This method results in too many times of installation and demolition of the support, greatly prolonging the process conversion time, reducing the construction efficiency and increasing the input cost of the installation and demolition of the support.

[0004] Therefore, it is necessary for the inventor to design a new movable support for bridge construction to overcome the above problems. Summary of the Invention

[0014] Preferably, the chute and the sliding part each include at least two, and each chute and the sliding part are arranged in parallel.

[0015] Preferably, the limiting plate and the sliding part are both made of plastic.

[0016] Preferably, an anti-tipping component is fixedly arranged between the scaffold body and the ground.

[0017] Preferably, the anti-tipping component includes a stay cable and an insertion rod. One end of the stay cable is fixedly arranged on the scaffold body, the other end of the stay cable is fixedly connected to the insertion rod, and the insertion rod is inserted into the ground.

[0030] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will detail this application with reference to the accompanying drawings and in conjunction with the embodiments.

[0031] Such as Figure 1 、 Figure 2As shown in the figure, a movable support for bridge construction includes a chute 1, a sliding bottom plate 2 and a scaffolding body 3; among which: the scaffolding body 3 is fixedly connected to the sliding bottom plate 2; the chute 1 is fixedly arranged on the ground 4, and the bottom of the sliding bottom plate 2 is slidably connected to the chute 1; a fixing member for fixing the sliding bottom plate 2 to the ground 4 is also detachably connected to the sliding bottom plate 2.

[0032] Specifically, after determining the construction position of the bridge pier 12, chutes 1 are pre-opened around the pier 12, and then the chutes 1 and the sliding bottom plate 2 are slidably installed. When the construction of the pier 12 is required, usually the support is relatively close to the construction position. At this time, the sliding bottom plate 2 is slid to a position closer to the pier 12 and then fixed by a fixing member. Then, the scaffolding body 3 is assembled on the sliding bottom plate 2 as a support. When the construction of the pier 12 is completed and the construction of the capping beam 13 is required, the position of the support is farther than the position of the support for the pier 12. At this time, the fixing member is removed to make the sliding bottom plate 2 in a slidable state, and then the sliding bottom plate 2 is pushed to the position for the construction of the capping beam 13. During this process, there is no need to remove the scaffolding body 3 from the sliding bottom plate 2. The height of the support for the capping beam 13 is relatively high, and it can be directly heightened on the top of the scaffolding body 3 of the original support for the pier 12 to meet the construction requirements of the capping beam 13. It should be noted that during the sliding process of the sliding bottom plate 2, it should maintain a parallel relationship with the pier 12, that is, the setting direction of the chute 1 should be perpendicular to the side wall of the pier 12, so as to ensure that the scaffolding body 3 does not deviate during the sliding process. In this embodiment, by installing the scaffolding body 3 on the sliding bottom plate 2 instead of directly fixing it on the ground 4, and slidably connecting the sliding bottom plate 2 to the chute 1 on the ground 4, the scaffolding body 3 can be switched between the construction position of the pier 12 and the construction position of the capping beam 13 without having to remove and rebuild the scaffolding, greatly shortening the process conversion time, improving the construction efficiency and reducing the input cost of the installation and removal of the support at the same time.

[0033] A limiting plate 5 that fits the inner wall of the chute 1 is fixedly arranged on the inner wall of the chute 1, and a sliding part 6 that cooperates with the limiting plate 5 is fixedly arranged at the bottom of the sliding bottom plate 2. Specifically, if the chute 1 is a dug pit directly on the ground 4, the sliding part 6 will squeeze the side wall of the pit during the sliding process, resulting in the deformation of the side wall of the pit, and then the position of the sliding bottom plate 2 will shift, and finally the position of the scaffolding will deviate. Therefore, the limiting plate 5 and the limiting part are placed inside the chute 1 for cooperation. The limiting plate 5 is not easily deformed, thus ensuring the accuracy of the direction of the sliding bottom plate 2 during the sliding process.

[0034] The cross-section of the chute 1 is a trapezoid with a larger upper part and a smaller lower part. Specifically, the larger opening at the upper part makes it more convenient to place the sliding bottom plate 2 from top to bottom.

[0035] The scaffolding body 3 includes a plurality of support rods 7. A base 8 is fixedly arranged at the bottom of the support rod 7. The base 8 is fixedly connected to the sliding bottom plate 2 through a plurality of bolts. Specifically, each support rod 7 is fixedly connected to the sliding bottom plate 2 through a plurality of bolts, ensuring the stability of the connection.

[0036] The fixing member includes a plurality of fixing pins 9. The fixing pins 9 penetrate through the sliding bottom plate 2 and are inserted into the ground 4. Specifically, the fixing pin 9 is provided with a pressing plate 14. After the pin is inserted into the ground 4, the pressing plate 14 presses the sliding bottom plate 2 against the ground 4. The pin can prevent the sliding bottom plate 2 from sliding on the ground 4 during the working state, causing danger. In actual use, a pull ring 15 is arranged on the pressing plate 14 to facilitate the extraction of the pin.

[0037] Both the chute 1 and the sliding part 6 include at least two. Each chute 1 and the sliding part 6 are arranged in parallel. Specifically, the plurality of chutes 1 and the sliding parts 6 make the movement of the scaffolding body 3 more stable and not prone to deviation in direction.

[0038] The limiting plate 5 and the sliding part 6 are both made of plastic. Specifically, the limiting plate 5 is a factory prefabricated product, which is adapted to the sliding part 6. The plastic material has a smooth surface, less resistance during sliding, and is more smooth. In addition, it can also be cast with concrete, which can be made on site, but the surface smoothness is relatively low, and the weight is also large, which is not convenient for repeated use. The plastic material can be repeatedly used during the construction of multiple piers 12.

[0039] A tipping prevention assembly is also fixedly arranged between the scaffolding body 3 and the ground 4. The tipping prevention assembly includes a stay cable 10 and an insertion rod 11. One end of the stay cable 10 is fixedly arranged on the scaffolding body 3, and the other end of the stay cable 10 is fixedly connected to the insertion rod 11. The insertion rod 11 is inserted into the ground 4. Specifically, since the scaffolding body 3 is fixedly arranged on the sliding bottom plate 2 and lacks a direct connection with the ground 4, the stability is slightly lacking. Therefore, the scaffolding body 3 is directly connected to the ground 4 through the stay cable 10 and the insertion rod 11, thereby ensuring the stability of the scaffolding.

[0040] The scaffolding body 3 is fixedly arranged in the middle of the sliding bottom plate 2. The fixing member is arranged around the outside of the scaffolding body 3. Specifically, the fixing pin 9 is arranged on the outer periphery of the scaffolding, making the force on the sliding bottom plate 2 more uniform, not prone to tipping and deviation, etc., and ensuring the safety of construction.

[0041] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and variations can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
