Side beam overturn-preventing device

Abstract

The utility model provides an anti-overturning device for a boundary beam. The anti-overturning device comprises a fixed seat and a supporting rod, a pit is formed in the bottom of the fixing base so that the fixing base can cover the check block of the cover beam. The stop blocks protrude out of the edge of the cover beam. The supporting rod is arranged above the fixing base and extends upwards. When the anti-overturning device for the boundary beam is used, the fixed seat is covered on the stop block at the edge of the cover beam, so that the fixed seat is fixed on the stop block. In this way, the edge beam overturn-preventing device is stably fixed and supported on the check block. Meanwhile, the supporting rods abut against the side wings of the edge beams upwards, and then the anti-collision guardrail above the side wings is effectively supported. In this way, the plate girder is prevented from tipping due to accidental collision in the construction process of hoisting and installing the secondary boundary beam.

Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction devices, in particular to a side beam anti-overturning device. Background Art

[0002] Plate beams are often used in bridge construction. Several plate beams are laid longitudinally on the cap beam and connected to each other to form a bridge deck. During the dismantling of the bridge, the plate beams are removed one by one. For example, if the edge beam needs to be removed, after the secondary side beam is removed, the side beam loses its lateral connection with other beams, and there are anti-collision guardrails on the edge of the top plate of the side beam. This will cause the side beam to be in an eccentrically compressed state. If the support is partially vacant, or if an accidental collision occurs during the lifting and installation of the secondary side beam, the side beam may overturn. However, the prior art lacks a device that can support the side beam. Utility Model Content

[0003] The utility model aims to provide a side beam anti-overturning device, which can support the side beam and thus prevent the side beam from overturning.

[0004] The embodiments of the present invention are implemented by the following technical solutions:

[0005] A side beam anti-overturning device comprises a fixing seat and a support rod; a pit is arranged at the bottom of the fixing seat so that the fixing seat can cover a stopper arranged on a cap beam; the stopper is protrudingly arranged on the edge of the cap beam; the support rod is arranged above the fixing seat and extends upward.

[0019] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0020] Example:

[0021] like Figure 1-Figure 3As shown, the utility model provides a side beam anti-overturning device, including a fixed seat 1 and a support rod. Generally, blocks 3 are provided on both sides of the cap beam 2. The block 3 is generally in the shape of a protruding rectangular parallelepiped. A pit is provided at the bottom of the fixed seat 1 so that the fixed seat 1 can cover the block 3 arranged on the cap beam 2. In practice, the fixed seat 1 can be composed of 5 steel plates. Four of them are enclosed in a rectangle, and the other one is arranged above the rectangle, thereby forming an inverted box shape. The cavity formed inside the fixed seat 1 is the pit. The size of the pit is slightly larger than the size of the block 3. The fixed seat 1 can just cover the outside of the block 3 and wrap the block 3. In this way, the fixed seat 1 is fixed and supported on the block 3. The support rod is arranged above the fixed seat 1 and extends upward.

[0022] like Figure 1 In the scene shown, the rightmost side beam is not connected to other plate beams 11, and the anti-collision guardrail 13 is in a suspended state. When the side beam anti-overturning device of the utility model is used, the fixing seat 1 is covered with the block 3 on the edge of the cap beam 2, so that the fixing seat 1 is fixed to the block 3. This also makes the side beam anti-overturning device stably fixed and supported on the block 3. At the same time, the support rod presses the side wing 12 of the side beam upward, thereby effectively supporting the anti-collision guardrail 13 above the side wing 12. This prevents the plate beam 11 from accidentally colliding and tipping over during the construction process of lifting and installing the secondary side beam. In addition, the structure of this device is very simple, and it can be removed and reused after the construction is completed. It should be noted that the side beam mentioned in the utility model is actually a type of plate beam 11, and it is called a side beam because it is placed on both sides of the bridge. Due to its special placement position, the side wing 12 for installing the anti-collision guardrail 13 needs to be set on its edge.

[0023] In this embodiment, the fixing seat 1 is provided with a fixing screw 4. The fixing screw 4 is threadedly connected to the fixing seat 1 and can extend into the inside of the fixing seat 1. In practice, the sizes of the stoppers 3 of different cap beams 2 are different. The cavity of the fixing seat 1 can be set to be larger, so that the fixing seat 1 can be covered on top of most of the stoppers 3. In order to ensure that the upper fixing seat 1 and the stopper 3 can be stably connected, the fixing screw 4 can be tightened at this time. That is to say, after the fixing screw 4 is tightened, the fixing screw 4 presses against the stopper 3 inside the fixing seat 1, thereby achieving a fixing effect. This arrangement also enables the side beam anti-overturning device of the utility model to be adapted to more types of cap beams 2.

[0024] In this embodiment, two adjacent surfaces of the fixing seat 1 are provided with fixing screws 4. This enables the fixing seat 1 to clamp the stopper 3 from two directions, thereby better ensuring the connection stability.

[0025] In this embodiment, the support rod includes a telescopic tube 6 and a telescopic rod 7. The lower end of the telescopic tube 6 is connected to the top of the fixed seat 1. The telescopic rod 7 is inserted into the telescopic tube 6 and can be telescopic relative to the telescopic tube 6. In practice, the outer diameter of the telescopic rod 7 is slightly smaller than the inner diameter of the telescopic tube 6. This allows the telescopic rod 7 to slide relative to the telescopic tube 6 and will not swing too much relative to the telescopic tube 6. This ensures the support stability of the support rod to the side wing 12. The outer wall of the telescopic rod 7 is provided with threads, and the nut 8 is threadedly connected to the telescopic rod 7. The outer diameter of the nut 8 is larger than the inner diameter of the telescopic tube 6.

[0026] When in use, the nut 8 is threadedly connected to the telescopic rod 7 and one end of the telescopic rod 7 is inserted into the interior of the telescopic cylinder 6. When the nut 8 abuts against the telescopic cylinder 6, the telescopic rod 7 will not be able to move further downward. We can set the sum of the lengths of the telescopic cylinder 6 and the telescopic rod 7 to be smaller than the distance between the side wing 12 and the block 3. This allows the entire side beam anti-overturning device to be easily inserted into the gap between the side wing 12 and the block 3. Then, by twisting the nut 8, the telescopic rod 7 can be gradually moved upward, thereby tightening the side wing 12. This setting makes it very easy to put in and take out the entire device, and is convenient for operation.

[0027] In addition, there is no fixed connection between the telescopic cylinder 6 and the telescopic rod 7, so that the two can be separated and assembled at will. Therefore, the telescopic rod 7 can be selected to a suitable length as needed and matched with the telescopic cylinder 6 for use, making the use of the entire device more flexible.

[0028] In this embodiment, a support pad 9 is provided on the top of the telescopic rod 7. The area of ​​the support pad 9 is larger than the cross-sectional area of ​​the telescopic rod 7. The support pad 9 is provided so that the contact area between the support pad 9 and the side wing 12 is larger than the contact area between the telescopic rod 7 and the side wing 12. This reduces the pressure on the side wing 12 and avoids damage to the side wing 12.

[0029] In this embodiment, a through hole 10 is provided at the top of the fixing seat 1 to communicate with the interior of the telescopic cylinder 6. That is to say, the through hole 10 inside the telescopic cylinder 6 directly passes through the top of the fixing seat 1. At the construction site of the bridge, due to the complex environment, it is easy for some debris to enter the telescopic cylinder 6, which may affect the telescopic movement of the telescopic rod 7. By providing the through hole 10 at the top of the fixing seat 1, the debris entering the interior of the telescopic cylinder 6 can be leaked out through the through hole 10, thereby avoiding the debris left inside the telescopic cylinder 6.

[0030] In this embodiment, the fixing screw 4 is provided with a rotating handle 5. By twisting the rotating handle 5, the fixing screw 4 can be extended or extended. This makes it easier to twist the fixing screw 4 without the need for external tools, making the operation simpler.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
