Description

Technical Field

[0001] This invention belongs to the field of engineering structure construction technology, and in particular relates to an adjustable railing device for construction trestle. Background Technology

[0002] Construction trestle bridges are commonly used structures in on-site construction of engineering projects, enabling on-site engineering work. However, sometimes concrete mixer trucks need to stand on the trestle bridge for pouring work. Often, the height of the railings is too high, restricting the pouring work. On the other hand, if the railings are set too low, it will not meet the requirements of the construction specifications. Therefore, other auxiliary measures are usually required, which brings a lot of inconvenience to on-site construction, affects construction efficiency, and wastes manpower and resources. Summary of the Invention

[0003] In view of this, the present invention aims to overcome the defects in the prior art and proposes an adjustable railing device for construction trestle bridges.

[0004] To achieve the above objectives, the technical solution created by this invention is implemented as follows: An adjustable railing device for a construction trestle includes several railing segments, each segment comprising a base and an adjustable portion. The base includes lower supports on both sides, with several lower supports horizontally arranged between the two lower supports. The adjustable portion includes upper supports on both sides, with several upper supports horizontally arranged between the two upper supports. The upper end of the lower supports has a mating part corresponding to the upper supports. An auxiliary tie rod is installed on the outside of the mating part, with its upper end rotatably mounted to the mating part and its lower end having a pin hole. The upper part of the upper support has a mating hole matching the pin hole. Under normal conditions, the upper support is vertically arranged and fixed to the mating part by two hinges arranged side by side, and at least one hinge is detachable.

[0005] Furthermore, the hinge element is a hinge pin.

[0006] Furthermore, the inner surface of the upper support is flush with the inner surface of the lower support.

[0007] Furthermore, a kick plate is provided at the lower end of the adjustable part.

[0008] Furthermore, the bottom of the lower support is provided with a connecting plate, which is L-shaped, with one end fixed to the lower support and the other end provided with a connecting hole.

[0009] Furthermore, both the upper support and the lower support are made of steel pipes.

[0010] Furthermore, the lower end of the upper support is designed as an arc-shaped structure.

[0011] Furthermore, both the upper support and the lower support adopt a plate-like structure.

[0012] Furthermore, the length of the mating part is 1 / 3 to 1 / 3 of the total length of the lower support.

[0013] Furthermore, the top of the upper support is lower than the top of the mating part, or the top of the upper support is flush with the top of the mating part.

[0014] Compared with existing technologies, the present invention has the following advantages: This invention provides an adjustable railing device for construction trestle bridges. It is easy to install, saves time and labor, and has low operating costs. The adjustable part can open and close at a certain angle to lower the railing height, thereby enabling efficient construction on site. It meets both the construction requirements of concrete mixer trucks on the trestle bridge and the standard design height requirements for trestle bridge railings in daily use. Adjusting the height is extremely convenient, saving time and labor, and is highly beneficial for efficient on-site construction. Attached Figure Description

[0019] The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] An adjustable railing device for a construction trestle, such as Figures 1 to 8 As shown, the railing includes several railing segments 1, each of which includes a base part 2 and an adjustable part 3. The base part includes lower supports 4 on the left and right sides, and several lower supports 5 are horizontally arranged between the two lower supports. The adjustable part includes upper supports 6 on the left and right sides, and several upper supports 7 are horizontally arranged between the two upper supports. The upper end of the lower support is provided with a mating part 8 corresponding to the upper support. An auxiliary pull rod 9 is installed on the outside of the mating part. The upper end of the auxiliary pull rod is rotatably installed on the mating part, and the lower end is provided with a pin hole 10. The upper part of the upper support is provided with a mating hole 11 that matches the pin hole. Typically, the length of the mating part is 1 / 3 to 1 / 3 of the total length of the lower support.

[0021] The base section has lower supports on both sides, with several horizontal supports distributed between them, forming a stable base and providing solid foundation support for the entire railing system. The adjustable section has upper supports on both sides, with several horizontal supports distributed between them, forming the main adjustable structure. The upper and lower sections work together to form a complete railing system, laying the foundation for subsequent adjustability and ensuring construction safety.

[0022] Under normal conditions, the upper support is vertically arranged and fixed to the mating part by two hinges 12 arranged side by side, and at least one hinge is detachable. Specifically, the lower part of the upper support has a hinge hole 17, and the middle part of the lower support has a positioning hole corresponding to the hinge hole. For example, the hinge is a hinge pin, which passes through the hinge hole and the positioning hole in sequence to fix the upper and lower supports. When one of the hinge pins is removed, the remaining hinge pin can be used as a pivot to facilitate the rotation and adjustment of the upper support. When the adjustable part needs to be adjusted, only one hinge is removed, and the upper support is rotated around the other hinge as an axis to tilt the adjustable part, thereby reducing the total height of the railing device and changing the angle of the railing device. When the pin hole of the auxiliary rod is aligned with the mating hole of the upper support, the positioning pin is inserted to fix the adjustable part, at which point the adjustable part is tilted.

[0023] When construction equipment such as large cranes operate on the trestle bridge (e.g., concrete mixer trucks need to stand on the trestle bridge for pouring), a large operating space may be required. In this case, by adjusting the adjustable part, the height and angle of the railing can be changed, allowing the adjustable part to be in a tilted state, thus creating sufficient space for the construction equipment and ensuring its smooth operation. This adjustable design means that the railing device is no longer a fixed protective structure, but can be flexibly adjusted according to different scenarios and needs during the construction process. This greatly improves its adaptability to the construction environment, effectively avoiding obstacles to construction caused by fixed railings, and providing a strong guarantee for the smooth progress of construction.

[0024] The inner surface of the upper support is flush with the inner surface of the lower support, and the top of the upper support is lower than the top of the mating part, or the top of the upper support is flush with the top of the mating part. This prevents the upper end of the upper support from scraping against other structural components when the upper support is rotated for adjustment. To further improve safety, a kick plate 13 can be provided at the lower end of the adjustable part.

[0025] Both the upper and lower supports are made of steel pipes. The upper support has an upper through hole 15 corresponding to the upper support, and the lower support has a lower through hole 16 corresponding to the lower support. The lower through hole can be used to pass through the corresponding lower support, and the upper through hole can be used to pass through the corresponding upper support. In addition, the upper through hole can also serve as a mating hole for connecting the auxiliary tie rod. That is, when the auxiliary tie rod is rotated until the pin hole corresponds to the through hole of the upper support, the positioning pin can be inserted, and the tilted adjustable part can be fixed by the auxiliary tie rod.

[0026] The lower end of the upper support is designed with an arc shape, which allows for easy rotation of the upper support and prevents the lower end of the upper support from rubbing against the lower support. Both the upper and lower supports are plate-like structures. Typically, a connecting plate 14 is provided at the bottom of the lower support. The connecting plate is L-shaped, with one vertical end fixed to the lower support and a connecting hole at the horizontal end. By inserting bolts through the connecting hole, this railing device can be installed on the trestle bridge's auxiliary facilities.

[0027] This invention provides an adjustable railing device for construction trestle. The basic and adjustable parts adopt a modular design, allowing components to be prefabricated in the factory and then transported to the construction site for rapid assembly. When adjusting the height and angle of the railing during on-site construction using concrete mixer trucks, simply remove one hinge and use the other hinge as a pivot to rotate the adjustable part, achieving a certain angle of tilt and facilitating on-site construction. This is achieved through a simple connection between the mating parts and auxiliary tie rods. Construction workers can easily install and adjust railing segments without complex tools or specialized skills, significantly shortening construction time and improving installation efficiency. The flexible adjustment function of the adjustable part allows for quick adjustment of the railing height and angle according to different construction needs, such as the size of construction equipment, space limitations, and safety requirements at different construction stages. This effectively solves the problem that traditional fixed railings cannot meet diverse needs during construction, greatly improving the applicability of construction trestle and ensuring the smooth progress of construction.

[0028] The robust foundation provides solid support for the entire railing system, ensuring its stability in various complex construction environments. The adjustable design allows for flexible adjustments to the railing's position without compromising construction safety, preventing obstruction of construction due to fixed railings, reducing safety hazards during construction, and providing reliable protection for construction workers' lives. This adjustable railing system for construction trestle bridges, with its advantages of convenient installation, strong adaptability, and reliable safety, provides powerful support for the safety protection of construction trestle bridges and the smooth progress of construction, possessing high practical value and significant potential for widespread adoption.

[0029] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
