Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of engineering construction protection application research, and specifically relates to an assembled edge protection railing system. Background Art
[0002] The edge guardrails used in existing road construction and bridge construction are mostly in the form of iron fence structures, mesh guardrails, temporary steel pipe guardrails, etc. However, guardrails with this structure have the following problems: the mesh is easy to damage and entangle, and the service life is limited. The guardrails with iron fence structures and temporary steel pipe guardrails are too heavy, which is not conducive to the handling of the guardrails, inconvenient transportation, and easy to deform and twist, making maintenance inconvenient. In addition, the crossbars and columns of the steel pipe guardrail structure need to be transported to the site for temporary welding. There are many welding points and a large amount of work, which has a great impact on the construction progress. It requires a large amount of personnel and equipment investment during dismantling. In addition, the dense wire mesh on the guardrail is generally tied with wire. After a long time, the wire will rust and there is a risk of falling off.
[0003] In the prior art, a Chinese patent document with a publication number of CN220621178U and a publication date of March 19, 2024 discloses a guardrail positioning rod and an assembled edge safety guardrail, comprising at least two guardrail positioning rods and a horizontal railing device connected between two adjacent guardrail positioning rods. The guardrail positioning rod comprises a vertical rod and a positioning device fixed to the lower end of the vertical rod, and at least one connecting plate is fixed on the vertical rod body, and a plurality of mounting holes that can be respectively installed and matched with the horizontal railing device are opened on the connecting plate. After the guardrail positioning rod is fixed to the ground through the positioning device, each mounting hole can be installed with a corresponding horizontal railing device, and the horizontal railing device can also be installed in the mounting hole at the corresponding angle position of the connecting plate according to actual needs. However, the vertical rod and the horizontal railing device of the patent need to be installed through the connecting plate, and the connecting plate is a circular ring with a mounting hole. The horizontal railing device needs to be fixed to the connecting plate through buckles or bolts, which is relatively cumbersome during installation. After being subjected to force, the buckles, bolts and even the connecting plate are easily deformed, which is not conducive to disassembly and reuse. Utility Model Content

[0022] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.
[0023] Example 1
[0024] like Figure 1 As shown, the assembled edge protection railing system of the utility model includes a column 1, a cross bar 2, an extension rod 4, and a base 3. A plurality of cross bars 2 are provided, and the plurality of cross bars 2 are respectively vertically fixedly connected to the column 1. The extension rod 4 is detachably inserted into the end of the cross bar 2, and the base 3 is fixedly connected to the bottom of the column 1.
[0025] Example 2
[0026] On the basis of Example 1, the column 1 and the extension rod 4 of this embodiment are both cylindrical hollow tubes. Specifically, the column 1 adopts a 120 cm long φ50 mm steel pipe, and the extension rod 4 adopts a φ42 mm steel pipe. The length of the extension rod 4 can be adjusted according to the actual construction conditions, and both ends of the extension rod 4 can be treated with anti-corrosion and anti-rust.
[0027] The cross bars 2 are evenly spaced on the columns 1. In this embodiment, a cross bar 2 is provided for every 35 cm increase in height from the bottom of the column 1 to the top of the column 1, and a total of three cross bars 2 are provided.
[0028] like Figure 2 As shown, each crossbar 2 includes a first crossbar 21 and a second crossbar 22 arranged in pairs, and each pair of the first crossbar 21 and the second crossbar 22 has the same horizontal height. The first crossbar 21 and the second crossbar 22 are both cylindrical hollow tubes, specifically, φ50mm steel tubes with a length of 15cm.
[0029] The first crossbar 21, the second crossbar 22 and the column 1 are connected by prefabrication welding, which can be directly transported to the backyard for standby. The backyard mainly refers to the area of processed materials or finished products prepared for the construction site. Prefabrication welding refers to pre-processing and installing parts in the factory or manufacturing plant before welding. This welding method is more efficient and accurate because all prefabrication work can be carried out in a factory environment, and the welding quality can be accurately controlled to ensure that the weld quality meets the standards, reduce welding work on the construction site, avoid the harm of on-site welding to the environment and workers, reduce on-site construction time and labor costs, and improve the efficiency and standardization of construction. During prefabrication and welding, the layout direction of the edge protection railing can be changed by changing the angle between each pair of first cross bars 21 and second cross bars 22 on the column 1. For example, when the edge protection railing is set vertically, the angle between the first cross bar 21 and the second cross bar 22 is 180°; when the edge protection railing needs to be set at a right angle, the acute angle between the first cross bar 21 and the second cross bar 22 is 90°. Different angles can be prefabricated and welded in advance to meet actual needs.
[0030] like Figure 3As shown, the base 3 is provided with adjustment holes 7, and 4 adjustment holes 7 are evenly arranged around the circumference of the column 1. The adjustment holes 7 are long holes. Some ground conditions are not good for installation. The adjustment holes 7 are convenient for fine-tuning the installation position, simplifying the installation process and improving the installation efficiency. During installation, expansion bolts 6 are used to penetrate the adjustment holes 7. In this embodiment, the base 3 is made of a steel plate with a thickness of 6 mm.
[0031] The column 1 is also provided with a hook 5, which can directly hang the dense mesh protection net, effectively solving the problem of long-term rusting of traditional steel wire binding and complicated installation and removal. In this embodiment, two hooks 5 are provided, located at the upper and lower parts of the column 1 respectively, and φ6mm round steel is used. The upper round steel is tilted upward, and the lower round steel is tilted downward, which can prevent the dense mesh protection net from falling off.
[0032] The working process of the utility model is as follows: the column 1 and the cross bar 2 are welded as a whole in the back field. When installing on site, the column 1 is first bolted and fixed to the concrete floor through expansion bolts 6 or pre-buried screws. The installation distance can be adjusted according to the actual situation on site. Then, one end of the extension rod 4 is directly inserted into the cross bar 2, and then the other end of the extension rod 4 is inserted into the next cross bar 2 to be installed, and then the column 1 is fixed to the concrete floor, and repeated until the construction is completed.
[0033] The utility model achieves assembly through the socket-type connection process, realizes convenient installation and disassembly, achieves rapid turnover, improves use value and utilization rate, and at the same time greatly improves the standardization of protective guardrails, reduces costs, is not easily deformed and can be reused, and improves safety and environmental protection.
[0034] Components and structures not described in detail in the embodiments are well-known components and common structures or common means in the industry and are not described one by one here.
