[0001] The utility model relates to the technical field of bridge engineering, in particular to a sliding buckle type quick-assembly safety guardrail column. Background Art

[0002] Steel trestle is a kind of bridge that can be quickly assembled and erected, used to cross obstacles such as gullies and rivers, and used as a transportation channel and construction platform for machinery, raw materials and workers. The structure of the existing steel trestle can be found in the Chinese invention patent with publication number CN115637648A. It is mainly composed of Bailey frame, transverse distribution beam, longitudinal distribution beam and steel bridge deck. The distribution beam is usually made of I-beam.

[0003] In addition, to ensure construction safety, safety guardrails need to be installed on both sides of the steel trestle, and the connection between the safety guardrail and the trestle is mostly bolt connection or on-site welding. Among them, bolt connection requires tightening a large number of bolts, which is a lot of work and time-consuming and laborious to install; and on-site welding requires full welding of the bottom of the guardrail column to ensure a firm installation, which is also a lot of work; at the same time, whether bolt connection or on-site welding is used, there is also the problem of inconvenience in disassembling the safety guardrail.

[0025] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0026] See also Figure 1-2 The utility model provides a sliding buckle type quick assembly safety guardrail column, which is used to buckle with the top I-beam of the Bailey frame and be used in conjunction with the railing 2. For details, please refer to Figure 3-7 The guardrail column includes a column body 1 and a base 6. The bottom end of the column body 1 is fixedly connected to the top end of the base 6. The base 6 includes a bottom plate 61 connected to the column body 1. Limiting plates 62 are respectively provided on both sides of the bottom plate 61. The two limiting plates 62 and the bottom plate 61 are surrounded by a U-shape to facilitate the buckling with the I-beam at the top of the Bailey frame. Obviously, if the size is appropriate, standard channel steel can be directly selected and cut to be used as the base. The two limiting plates 62 are each provided with a limiting block 63 on the opposite side. The limiting block 63, the limiting plate 62 and the bottom plate 61 are surrounded to form a sliding buckle connection relationship with the wing plate at the top of the I-beam.

[0027] Obviously, in order to ensure that the base 6 slides smoothly into the I-beam, the distance between the limit block 63 and the bottom plate 61 needs to be greater than the thickness of the I-beam wing plate. Therefore, after the base 6 slides into the I-beam, a certain installation gap will be formed between the top surface of the limit block 63 and the bottom surface of the wing plate. Generally, a thin steel plate is filled between the bottom plate 61 and the wing plate to reduce or eliminate the gap to avoid obvious shaking of the guardrail column after installation. The present application also provides another solution to prevent shaking, that is, a gap adjustment screw hole (not shown) is opened on the top surface of the bottom plate 61, and a set screw is pre-threaded and connected, and the set screw is tightened after the base slides into the I-beam to a predetermined position.

[0028] The guardrail column can be quickly assembled with the I-beam at the top of the Bailey frame in the form of a sliding buckle connection, and the gap between the column base and the top surface of the I-beam can be adjusted by filling the steel plate to avoid obvious shaking of the guardrail column. After that, the two column bodies opposite to each other on both sides of the steel trestle are welded together through angle steel, and the bridge deck steel plate is laid between the two rows of guardrail columns to complete the stable installation of the guardrail column and the steel trestle. Finally, the railing and safety net can be installed between the adjacent column bodies. The operation is simple and efficient. Among them, the installation of the railing can be carried out in various forms such as threaded connection, welding or plug-in. For example, multiple through holes can be opened on the surface of the column body 1 for the railing 2 to be inserted, and the adjacent railings 2 are connected by an extension member 5. The pipe extension member 5 is more common and will not be introduced in detail here. This application uses a 12mm steel plate as the column body, and a double-sided welding seam of 12mm is used between the column body and the base, and a single-sided welding seam of 12mm is used between the column body and the angle steel, and a welding rod of the corresponding strength grade needs to be matched.

[0029] As a further improvement to the above solution, the top surface contour of the limit block 63 is adapted to the bottom surface contour of the I-beam wing plate, so that after the base 6 is buckled with the I-beam and the gap is adjusted, the top surface of the limit block 63 fits with the bottom surface of the wing plate. Preferably, an elastic cushion layer is provided on the top surface of the limit block 63, and the elastic deformation ability of the elastic cushion layer is used to further enhance the tightness of the fit.

[0030] As a further improvement to the above scheme, please refer to Figure 5-6 The stop block 63 is connected to the stop plate 62 by screws, so that the screws can be screwed to fine-tune the distance between the stop block 63 and the I-beam flange according to operating experience when necessary, or replace the stop block 63 with a new one after the existing stop block 63 is worn. Generally speaking, the thickness error of the I-beam flange produced by the same manufacturer and the same batch is small. Therefore, usually a certain I-beam is used as a mold, and the stop block 63 and the base 6 are installed and fixed in the workshop. If welding is used, such as Figure 7 As shown, the spacing between the stop block 63 and the bottom plate 61 cannot be changed. When I-beams from multiple batches and manufacturers are mixed, the actual I-beam may not be able to slide into the base 6 due to the large error between the wing plate thickness and the mold. In this case, the spacing between the stop block 63 and the bottom plate 61 can be fine-tuned by screwing the screws.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents. These modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the utility model, and they should all be included in the scope of the claims and specification of the utility model.
