Description

Technical Field

[0001] The utility model relates to the technical field of bridge guardrails, in particular to a bridge guardrail steel structure which is easy to assemble. Background Art

[0002] Bridge guardrails refer to guardrails installed on bridges. Their purpose is to prevent out-of-control vehicles from going over the bridge. They have the functions of preventing vehicles from breaking through, passing under, or climbing over the bridge, as well as beautifying the bridge structure. There are many ways to classify the types of bridge guardrails. In addition to classification by installation location, they can also be classified by structural characteristics, anti-collision performance, etc. According to the installation location, they can be divided into bridge side guardrails, bridge central median guardrails, and pedestrian and lane boundary guardrails; according to structural characteristics, they can be divided into beam-column guardrails, reinforced concrete wall guardrails, and combined guardrails; according to anti-collision performance, they can be divided into rigid guardrails, semi-rigid guardrails, and flexible guardrails. Common guardrail forms include concrete guardrails, corrugated beam guardrails, and cable guardrails.

[0003] At present, most of the road and bridge guardrails on the market are assembled and spliced ​​through segmented guardrails. This assembled guardrail usually adopts a plate shape to prevent and protect pedestrians and vehicles. However, when splicing this plate-shaped guardrail, a large number of bolts need to be installed at the splicing point to ensure that the plates will not be broken and separated due to external force collision. This installation method requires pre-embedding and splicing, which consumes a lot of manpower and the installation method is relatively cumbersome. Utility Model Content

[0021] The existing bridge guardrail steel structure mainly adopts the technical solution of assembling and splicing segmented guardrails. However, when splicing the plate-shaped guardrails, a large number of bolts need to be installed at the splicing points to ensure that the plates will not be broken or separated due to external force collision. This installation method requires pre-embedding and splicing, which consumes a lot of manpower and is relatively cumbersome. Therefore, the applicant has developed a bridge guardrail steel structure that is easy to assemble, such as Figure 1-4 As shown, it includes: the embedded mounting seat 1 embedded on the bridge also includes a positioning column 3, and the positioning column 3 is fixed in the embedded mounting seat 1 through the provided plug-in connector 2. In actual operation, the bottom of the positioning column 3 is set to a raised rectangular shape, and the plug-in connector 2 is installed at the raised part, and the raised part can be embedded in the embedded mounting seat 1, and the side wall of the raised part is provided with a fence, so that the positioning column is arranged in a stepped retracted shape from top to bottom, and a fixing column 4 is inserted on one side of the positioning column 3. The positioning column 3 and the fixing column 4 are spliced ​​into a bridge column, and the positioning column 3 and the fixing column 4 are spliced ​​into a bridge column. Openings are opened relatively on the top and pieced together to form guardrail holes 5 that are interconnected. The guardrail holes 5 are mainly provided to facilitate the passage and positioning of guardrail plates, steel cables or steel pipes installed on the bridge, thereby playing the role of fencing both sides of the bridge; a reinforcement block 8 is also inserted at the top of the end of the positioning column 3 and the fixing column 4 that is away from the embedded mounting seat 1. The reinforcement block 8 is provided to further enhance the connection tightness of the present application. Secondly, in actual operation, the top of the reinforcement block 8 is set to a triangular shape to ensure that the arms on both sides of the reinforcement block 8 are evenly stressed. Secondly, it adds a warning to play a preventive role.

[0022] The positioning column 3 is provided with a mounting groove 31 for accommodating the plug-in column, and the plug-in component 2 includes: a spring 21 horizontally fixed in the mounting groove 31 of the positioning column 3, and the other end of the spring 21 extends toward the open end of the mounting groove 31 of the positioning column 3 and is connected to a positioning block 22. In actual operation, the positioning block 22 of the present application is preferably set to a horizontally placed right-angled trapezoidal shape, and the inclined surface 72 is located outside the opening of the mounting groove 31 and is set toward the embedded mounting seat 1.

[0023] In order to increase the stability of the installation of the present application, the present application preferably installs the connectors 2 on the side walls of the positioning column 3 in a one-to-one correspondence, that is, the connectors 2 are installed on the four side walls of the positioning column 3.

[0024] A locking piece 6 is installed on the side of the fixing column 4 facing the positioning column 3. The locking piece 6 is arranged along the extension direction of the fixing column 4 and fixed on the two side end walls of the fixing column 4; a limiting block 7 matching with the locking piece 6 is provided on the side of the positioning column 3 facing the fixing column 4.

[0025] The locking member 6 (which can be set in an I-shaped plate shape) but the present application preferably includes: a fixing member 61 set in a frustum shape, the fixing member 61 is fixed on the fixing column 4, and the fixing member 61 gradually gathers at one end away from the fixing column 4 and is fixedly connected to a vertical plate 62.

[0026] The limiting block 7 is provided with a vertical groove 71 for accommodating the vertical plate 62 and a slope 72 matching the fixing member 61, and the vertical groove 71 is connected to the slope 72, so that the fixing member 6 can be completely accommodated in the limiting block 7, and the side walls of the fixing column 4 and the positioning column 3 can fit tightly.

[0027] The reinforcement block 8 includes a protective block 81 and a mounting block 82 arranged perpendicular to the protective block 81, the protective block 81 extends in a direction away from the embedded mounting seat 1, and the mounting block 82 is partially and completely received in the mounting slot 9 opened between the positioning column 3 and the fixing column 4, and the end of the protective block 81 close to the mounting block 82 (i.e., the bottom end of the protective block 81) is received in the mounting slot 9. In actual operation, in order to ensure that the reinforcement block 8 is engaged, the opening at the top of the mounting slot 9 is arranged in a retracted shape, that is, smaller than the cross-sectional area of ​​the mounting block 82, so as to achieve effective limitation of the mounting block 82, and the opening at the top of the mounting slot 9 can allow the protective block 81 to pass through.

[0028] The guardrail holes 5 are arranged in a unidirectional array.

[0029] 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.
