Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and particularly relates to a dripping prevention device for casting highway bridge concrete guardrails. Background Technique

[0002] With the continuous development of China's transportation industry, the construction of expressways has gradually shifted to remote areas such as the northwest and southwest. Expressways pass through mountains and gullies more and more frequently. In order to adapt to complex terrain conditions, relatively high pier columns are usually constructed to ensure the stability and safety of highway bridges. The height of the constructed bridge pier columns is generally between 20 and 50 meters, and some are even higher. When pouring the concrete of the bridge deck guardrail under such working conditions, since there is a gap between the guardrail formwork and the precast beam, the concrete will fall from the high altitude through the gap, which may lead to incidents such as injuring people and damaging objects. To ensure the project quality and safety, a protective shed is usually set up to provide safety protection and prevent the concrete from falling. However, setting up a protective shed has problems such as a too large protective coverage area, a long setting-up time, and high costs. Summary of the Invention

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0030] See attached Figures 1 to 4, a schematic embodiment of the anti-dripping device for pouring the concrete guardrail of a highway bridge proposed by the present utility model is given. The anti-dripping device for pouring the concrete guardrail of a highway bridge is composed of a rod group 1 and a protection plate 2.

[0031] The rod group 1 includes a first rod 11, a second rod 12, and a third rod 13 connected in sequence. The included angle between the first rod 11 and the second rod 12 is 90°. The end of the first rod 11 is bent to be hung on the guardrail formwork 3. The length of the second rod 12 is greater than the height of the concrete guardrail 4. The included angle between the second rod 12 and the third rod 13 is not greater than 90°. The third rod 13 is located below the gap between the guardrail formwork 3 and the precast beam 5. In this embodiment, see the appendix Figure 1 , the length of the first rod 11 is 67 cm, of which the horizontal part is 57 cm long, and the bent end part is 10 cm long. The length of the second rod 12 is 170 cm.

[0032] The protection plate 2 is arranged on the second rod 12 and the third rod 13. The protection plate 2 is adaptively bent at the connection of the second rod 12 and the third rod 13. The protection plate 2 is used to block the dripping concrete. The size of the protection plate 2 is processed according to the actual construction requirements.

[0033] In order to stably support the protection plate 2, in this embodiment, there are multiple rod groups 1, see the appendix Figure 3 , adjacent rod groups 1 are arranged at an interval of 1 meter. Multiple rod groups 1 jointly support the protection plate 2, that is, jointly bear the weight of the protection plate 2, disperse the load to each rod group 1, reduce the burden on a single rod group 1, and improve the bearing capacity of the entire support structure. In addition, since the load is dispersed to multiple rod groups 1, when the protection plate 2 is subjected to pressure, local deformation is not likely to occur, and the stability is good.

[0034] To further improve the structural stability, in this embodiment, the anti-dripping device for pouring the concrete guardrail of a highway bridge further includes a fourth rod 14. The fourth rod 14 connects multiple rod groups 1, and the fourth rod 14 is fixed on the second rod 12. And there are multiple fourth rods 14, see the appendix Figure 2 , multiple fourth rods 14 are arranged at intervals along the length direction of the second rod 12. In this embodiment, adjacent fourth rods 14 are arranged at an interval of 45 cm. The first rod 11, the second rod 12, the third rod 13, and the fourth rod 14 are integrally connected, reducing the steps and workload in the assembly process, thereby reducing the assembly time and cost.

[0035] The end of the protective plate 2 located on the second rod 12 is the first end, and the end of the protective plate 2 located on the third rod 13 is the second end. The first end of the protective plate 2 is bent toward the second rod 12, and the second end of the protective plate 2 is in a hook shape to be hooked on the end of the third rod 13. In this way, the protective plate 2 can be firmly installed on the rod assembly 1.

[0036] When the cast concrete guardrail meets the set requirements, the anti-drip device for casting the highway bridge concrete guardrail can be removed. At this time, the concrete dripping on the protective plate 2 may fall. To avoid this situation, in this embodiment, the anti-drip device for casting the highway bridge concrete guardrail also includes a concrete bonding net 6. The concrete bonding net 6 is laid on the protective plate 2. The dripping concrete caught by the protective plate 2 initially sets on the concrete bonding net 6. When the anti-drip device for casting the highway bridge concrete guardrail is dismantled, the concrete can be prevented from falling, thereby improving the construction safety.

[0037] The end of the first rod 11 is bent and hooked on the guardrail formwork 3 to fix the anti-drip device for pouring concrete guardrails of highway bridges at a set construction position. In order to ensure that the device does not shake or shift during operation, in this embodiment, the anti-drip device for pouring concrete guardrails of highway bridges also includes a connecting piece, which is used to further connect and fix the first rod 11 and the guardrail formwork 3.

[0038] In this embodiment, the protective plate 2 is selected as a color steel tile. The surface of the color steel tile has been specially treated and has good corrosion resistance. Whether facing the erosion of rain, moisture or chemicals, it can maintain stability for a long time and is not easy to rust or damage. In addition, the color steel tile has high strength and is not easy to be damaged or deformed during installation and use.

[0039] In this embodiment, the first rod 11, the second rod 12, the third rod 13 and the fourth rod 14 are selected as φ12 round steel. φ12 round steel has certain strength and rigidity, is not easy to deform, can provide reliable support, and ensure the stability and safety of the structure. In addition, the price of φ12 round steel is relatively low, which can save costs.

[0040] In specific applications, lifting equipment can be used to install or dismantle the anti-drip device for pouring concrete guardrails of highway bridges.

[0041] In the above exemplary embodiment, the anti-drip device for pouring concrete guardrails of highway bridges can provide safety protection for the pouring construction of concrete guardrails, and has a simple structure, low cost, and high efficiency of on-site installation and disassembly. The provision of the concrete bonding net allows the dripping concrete that is blocked to be bonded to the net after initial setting, and when the anti-drip device for pouring concrete guardrails of highway bridges is disassembled, the concrete can be prevented from falling, thereby improving construction safety.

[0042] Finally, it should be noted that the embodiments in this specification are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. For the same or similar parts among the embodiments, reference can be made to each other.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: modifications can still be made to the specific implementation manners of the present invention or equivalent replacements can be made to some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
