Description
Technical Field
[0001] The utility model relates to the technical field of bridge construction, in particular to an anti-collision guardrail device. Background Art
[0002] In bridge construction, when erecting precast concrete beams, the deviation of the support shim during construction (within the allowable range of the specification of ±10mm) can easily cause the top surface elevation of the box beam to deviate from the design height, and the mid-span position of the precast beam has a pre-arch due to tensioning; in the continuous rigid frame part, the deviation between the pre-lift of the anti-collision guardrail template and the settlement of the template after pouring during the construction monitoring process causes misalignment between the segments, resulting in a linear broken line at the bottom of the flange plate, and some settlements are greater than the pre-lift, which will cause the top surface elevation of the anti-collision guardrail to be lower than the design height; in order to ensure the top surface line of the anti-collision guardrail, the anti-collision guardrail template must be adjusted, which can easily cause a gap between the bottom of the drip eave of the anti-collision guardrail and the flange plate of the box beam, which can easily cause leakage when the anti-collision guardrail is poured, thereby forming a honeycombed surface on the casting surface, and leakage can easily pollute the web of the box beam, causing quality risks and appearance pollution.
[0003] At present, in order to prevent leakage when adjusting the anti-collision guardrail template, the method used is: sticking a 10mm thick rubber strip on the end of the template, and using the rubber strip to seal the gap. However, only using the rubber strip to seal the gap will have the following shortcomings:
[0004] 1. The rubber strip is not firmly pasted and is easy to fall off. When the gaps are different, the rubber strips in the small gaps will be squeezed and deformed, resulting in uneven ends after pouring;
[0005] 2. When using rubber strips for sealing, the bottom of the rubber strips must be supported by pressure to ensure that the rubber strips do not move during the concrete pouring process. When the gap is large, additional rubber strips must be added, which leads to a long installation time and a complicated installation process.
[0006] The technical problem to be solved by this application is: to design an anti-collision guardrail device which can prevent leakage during adjustment and ensure the flatness of the casting end, and which is simple to install and easy to operate. Utility Model Content

[0026] 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.
[0027] Example 1: Please refer to Figure 1-3The utility model provides a technical solution: an anti-collision guardrail device, including an anti-collision guardrail template 1, the anti-collision guardrail template 1 is provided with a drip eave 10, the anti-collision guardrail template 1 includes a first template 12 and a second template 13 connected to each other, the drip eave 10 is located at the lower end of the second template 13, a first pull rod 14 and a second pull rod 15 are respectively provided between the first template 12 and the second template 13, the two ends of the first pull rod 14 and the second pull rod 15 are respectively connected to the first template 12 and the second template 13, and a mounting plate 16 for installing a street lamp fixedly connected thereto is also provided on one side of the second template 13. By providing the mounting plate 16 on one side of the second template 13, the convenience of installing the street lamp can be greatly improved, and there is no need to cut a groove on the ground for installation.
[0028] A slurry leakage prevention baffle 2 is provided on one side of the dripping eaves 10, and the slurry leakage prevention baffle 2 includes a connecting portion 21 and an abutting portion 22 fixedly connected to the connecting portion 21. The connecting portion 21 and the abutting portion 22 are integrally bent to form an L-shape between the connecting portion 21 and the abutting portion 22. The connecting portion 21 is mainly used to connect with the dripping eaves 10, so that the entire slurry leakage prevention baffle 2 is installed on the dripping eaves 10, and the abutting portion 22 is mainly used to fit tightly with the bottom of the box beam flange plate 3, so as to prevent slurry leakage during pouring, and also ensure that the pouring end surface is flat, and the angle between the connecting portion 21 and the abutting portion 22 is between 90° and 150°. Because the outer periphery of the drip eave 10 itself is an arc, setting the angle between the connecting portion 21 and the abutting portion 22 between 90° and 150° can facilitate the connection between the connecting portion 21 and the side of the drip eave 10, and can also ensure that the abutting portion 22 can fit tightly with the bottom of the box girder flange plate 3. A plurality of adjustment holes 20 are provided on the connecting portion 21 of the anti-leakage slurry baffle 2, and the adjustment holes 20 are strip-shaped. A connecting groove 11 corresponding to the adjustment hole 20 is also provided on the drip eave 10. The anti-leakage slurry baffle 2 is detachably connected to the drip eave 10 by using bolts to pass through the adjustment holes 20 and lock with the connecting groove 11.
[0029] Example 2: Please refer to Figure 4-5The utility model provides another technical solution: an anti-collision guardrail device, which is provided with any anti-collision guardrail device in the above-mentioned embodiment 1, and a pin shaft 23 that is rotatably connected to each other is provided between the connecting part 21 and the abutting part 22 in the anti-collision guardrail device, and the connecting part 21 and the abutting part 22 are rotatably connected to each other through the pin shaft 23.

By setting the connecting part 21 and the abutting part 22 to be rotatable to each other through the pin shaft 23, and providing a telescopic cylinder 25 for mutual support between the connecting part 21 and the abutting part 22, the angle between the connecting part 21 and the abutting part 22 can be adjusted, so that the anti-leakage baffle 2 can be suitable for installation at different side angles of the drip eaves 10, thereby improving versatility.
[0030] Example 3: Please refer to Figure 6 The utility model provides another technical solution: an anti-collision guardrail device, which is provided with any anti-collision guardrail device in the above-mentioned embodiment 1 or embodiment 2, and a sealing gasket 26 is also provided on the upper side of the abutment portion 22 in the anti-leakage baffle 2 in the anti-leakage baffle 2. The sealing gasket 26 is a rubber gasket. By providing a sealing gasket 26 on the upper side of the abutment portion 22, when the abutment portion 22 abuts against the lower end of the box beam flange plate 3, the sealing gasket 26 can greatly improve the anti-leakage effect of the anti-leakage baffle 2.
[0031] The working principle of the utility model is as follows: when the anti-collision guardrail device needs to be installed, the anti-leakage baffle plate 2 is first assembled on the dripping eaves 10 on the bridge deck, and then the first template 12 is installed by a crane, and the second template 13 is installed by a trolley, and then the first template 12 and the second template 13 are connected and installed with each other by the first tie rod 14 and the second tie rod 15 respectively. After the installation is completed, the measurement is notified to adjust the linear type of the guardrail template. After the adjustment is completed, the anti-leakage baffle plate 2 is adjusted to the abutment portion 22 to fit with the bottom of the box beam flange plate 3, and then the bolts are tightened to fix the anti-leakage baffle plate 2. By adjusting the adjustment on the anti-leakage baffle plate 2 The hole 20 is set in a strip shape, which can facilitate the adjustment of the installation position of the anti-leakage slurry baffle 2, so that the anti-leakage slurry baffle 2 can fit more closely to the box girder flange plate 3. By providing the anti-leakage slurry baffle 2 on the drip eaves 10 of the anti-collision guardrail device, the concrete can be well sealed during pouring, and the pouring end can be guaranteed to be flat, and there is no need to apply external force to the anti-leakage slurry baffle 2 to prevent it from shifting. The installation process is simple and convenient, with strong practicality, and it is applicable to bridge deck elevations that are higher or lower than the design value. Even when the box girder flange plate 3 is obviously misaligned and the edges and corners are missing due to the hoisting of prefabricated beams, the concrete can be well sealed.
