[0035] In order to facilitate the understanding of the guardrail skeleton reinforcing bar positioning equipment provided by the utility model, the application background thereof is introduced first. The concrete crash barrier, as an important part of the bridge deck, plays a key role in road safety. At present, most of the crash barriers are constructed by cast-in-place method, and the vertical skeleton reinforcing bar of the guardrail needs to be welded and fixed with the embedded reinforcing bar in the beam.

[0036] However, due to the arc surface of the crash wall, the vertical skeleton reinforcing bar presents a special-shaped structure, as shown in Figure 1 , and the construction surface of the guardrail skeleton reinforcing bar is a high-altitude working surface, which makes the positioning of the skeleton reinforcing bar very difficult.

[0037] Therefore, how to conveniently and safely position the skeleton reinforcing bar of the guardrail is an important issue to be solved at present.

[0038] Based on the above problems, the utility model provides a guardrail skeleton reinforcing bar positioning equipment, which can conveniently and safely position the skeleton reinforcing bar of the guardrail.

[0039] The guardrail skeleton reinforcing bar positioning equipment of the utility model will be described below in combination with Figures 1-3 .

[0040] Referring to Figure 2 and Figure 3The utility model provides a guardrail framework reinforcing steel bar positioning equipment, including base 10, stand 11, positioning column 12 and fixed height column 13, wherein, base 10 is used to support on the ground and provides the connecting foundation for other structures or parts, the bottom end of stand 11 is fixedly connected with base 10, positioning column 12 is spaced apart along the length direction of stand 11 multiple, and the extension direction of positioning column 12 is perpendicular to the height direction of stand 11, so that one end of positioning column 12 extends outward and forms the positioning end, and the positioning end of different positioning column 12 has respective preset extension distance, fixed height column 13 is connected to the top end of stand 11 and its extension direction is perpendicular to the height direction of stand 11.

[0041] In a specific application scenario, when positioning the reinforcing steel bar of the guardrail framework, first, the positioning equipment is carried to the side of the reinforcing steel bar of the framework on the bridge that needs to be positioned, the base 10 is supported on the bridge to provide support for the entire equipment, the positioning end of the positioning column 12 extends out of the stand 11 for positioning the waist profile of the reinforcing steel bar, specifically, the positioning end of different positioning column 12 has respective preset extension distance, by aligning the positioning end of different positioning column 12 with different inflection points of the waist of the reinforcing steel bar, the positioning of different inflection points of the waist of the reinforcing steel bar can be realized, and then the waist profile of the reinforcing steel bar is positioned through the inflection points; The fixed height column 13 can position the height of the reinforcing steel bar; After the positioning of a single reinforcing steel bar is completed, it is welded with the embedded reinforcing steel bar, and then the positioning equipment is moved along the reference line until the positioning of the reinforcing steel bar on the entire guardrail is completed, after the welding of the reinforcing steel bar of the guardrail framework is completed, the above positioning equipment can also be used for checking. Through the guardrail framework reinforcing steel bar positioning equipment provided by the utility model embodiment, the safe, convenient and accurate positioning of the reinforcing steel bar of the guardrail framework can be realized.

[0042] It should be noted that the reference line can be drawn by artificial using marking machine or other equipment, or can be formed by taking the position of the embedded reinforcing steel bar as the reference, no matter what kind of way is adopted, as long as the reference for the movement of the positioning equipment can be provided. In addition, universal wheels can also be installed at the bottom of the base 10 to facilitate the movement of the positioning equipment, reduce the manpower consumed in the equipment carrying process, and improve the positioning efficiency; at the same time, during the checking process, the equipment only needs to be pushed along the reference line, so that the checking can be conveniently and quickly completed, and the checking efficiency is improved.

[0043] The guardrail skeleton steel positioning device is integrally made of metal material, for example, can be formed by welding metal profiles or pipes. The stand column 11 is fixedly connected with the base 10 perpendicularly, and when the base 10 is supported on the ground, the stand column 11 is in a vertical state, and the extending direction of the positioning column 12 is perpendicular to the length direction of the stand column 11. According to the different surface shapes of the crash barrier wall, the positions and the number of the waist inflection points of the skeleton steel will also be different, therefore, the number, the arrangement positions on the stand column 11 and the extension distances of the positioning ends of the positioning columns 12 will also be different, and the specific number, the arrangement positions on the stand column 11 and the extension distances of the positioning ends of the positioning columns 12 are not limited in the embodiment of the utility model.

[0044] In order to improve the positioning accuracy, the guardrail skeleton steel positioning device further comprises a leveling structure 14 for leveling the base 10; the leveling structure 14 comprises a leveling screw 140 and a handle 141; wherein the leveling screw 140 is arranged on the base 10 and is threadedly connected with the base 10, and the bottom end of the leveling screw 140 is used for supporting on the ground; and the handle 141 is fixedly connected with the top end of the leveling screw 140. In actual work, when the bridge deck is uneven, the distance between the bottom end of the leveling screw 140 and the base 10 can be adjusted by rotating the handle 141, so that the base 10 is stably supported on the bridge deck, and the base 10 is ensured to be in a horizontal state.

[0045] According to actual requirements and the different structures of the base 10, the number and the arrangement positions of the leveling structures 14 will also be different, for example, three groups of leveling structures 14 can be arranged on the base 10 and arranged in a triangular shape, so that the leveling screws 140 of the three groups of leveling structures 14 can form three adjustable support points on the bottom of the base 10, and the front and rear and left and right tilting degrees of the base 10 can be adjusted. It can be understood that when universal wheels are arranged on the bottom of the base 10, the universal wheels can be connected with the bottom ends of the leveling screws 140.

[0046] In one specific embodiment of the utility model, the base 10 comprises a first beam 100 and a second beam 101, wherein the first beam 100 and the second beam 101 are fixedly connected perpendicularly, and the vertical column 11 is perpendicular to the plane formed by the first beam 100 and the second beam 101. Specifically, the first beam 100 and the second beam 101 can be fixed by welding; the extension direction of the first beam 100 is perpendicular to the extension direction of the positioning column 12, and the extension direction of the second beam 101 is parallel to the extension direction of the positioning column 12, and the first beam 100 and the second beam 101 jointly constitute the bottom support of the positioning device. The leveling structure 14 is provided with three groups, two of which are arranged at the two ends of the first beam 100, and the other is arranged at the end of the second beam 101 away from the first beam 100. In this way, the leveling screws 140 of the three groups of leveling structures 14 form three adjustable support points arranged in a triangle at the bottom of the base 10, which realizes stable support of the base 10 and ensures that the base 10 is in a horizontal state.

[0047] Of course, the leveling structure 14 includes but is not limited to the above-mentioned structure or form, and other structures or forms of the leveling structure 14 are also applicable as long as they can adjust the horizontal state of the base 10.

Specifically, the level 15 can be fixedly connected to the vertical column 11 by using a bolt or the like connecting member.

[0049] By using the above-mentioned positioning device, the specific specification of the guardrail skeleton steel bar can be conveniently and accurately positioned, but it cannot be used for other specifications of the guardrail skeleton steel bar.

[0050] In order to improve the applicability, referring to Figure 1 and Figure 2 , the positioning column 12 is slidably arranged in the vertical column 11, so that the extension distance of the positioning end can be adjusted to position different specifications of the guardrail. After the positioning end extends by a certain distance, the positioning column 12 needs to be positioned by the positioning structure to ensure the stability of the positioning column 12 and avoid the problem of sliding during positioning.

[0052] In a specific application scenario, when it is required to increase the extension distance of the positioning end, the two positioning nuts are screwed in a direction away from the positioning end, and when it is required to reduce the extension distance of the positioning end, the two positioning nuts are screwed in a direction close to the positioning end, so that the extension distance of the positioning end is adjusted and the positioning of the positioning column 12 is achieved.

[0053] It can be understood that the positioning structure includes but is not limited to the forms or structures listed above, and other structures or forms of positioning structures are also applicable, for example, the positioning column 12 is directly screwed to the stand column 11, and the specific setting can be performed according to actual requirements and application scenarios. In the embodiments of the present application, other structures or forms of positioning structures are not listed one by one.

[0054] In order to further improve the applicability, the height fixing column 13 and the stand column 11 can be arranged in a sliding fit and are positioned by a positioning member. Specifically, a sliding groove is arranged on one of the height fixing column 13 and the stand column 11, and a sliding block is arranged on the other one, and the sliding groove and the sliding block are slidably embedded. The positioning member can be a jacking screw, which is screwed to the sliding groove, and the end of the jacking screw is in abutting fit with the sliding block after penetrating through the groove wall of the sliding groove.

[0055] It can be understood that the height fixing column 13 and the stand column 11 are not limited to the above-mentioned fitting mode, and other modes such as sleeve fitting are also applicable. In addition, the positioning member is not limited to the above-mentioned structure or form, as long as it can achieve the corresponding positioning effect.

[0056] It can be understood that in order to improve the stability of the overall structure, reinforcing members such as reinforcing rods and reinforcing plates can be arranged between the stand column 11 and the base 10. The specific connection position and connection mode of the reinforcing members can be set according to actual requirements, and the embodiments of the present application will not be described in detail.
