Technical Field

[0001] The utility model relates to the technical field of road protection devices, in particular to a temporary protection device for highway construction. Background Art

[0002] In the high-speed reconstruction and expansion project, it is necessary to set up temporary protection on the unconstructed side. On the one hand, it is to prevent the night lights of oncoming construction vehicles from interfering with the normal driving section, and on the other hand, it is to prevent small stones and other objects splashed during the construction on the reconstruction and expansion side from causing danger to oncoming vehicles. At present, for the construction of temporary protection, usually expansion bolts are used to fix the rectangular brackets on the bridge fence, and then holes are drilled to lay color steel tiles. The construction is complex, and after the assembly of multiple brackets, a continuous and fixed structure cannot be formed, resulting in an unstable overall structure. At the same time, the overall structure is integral, which is not convenient for handling and installation. Summary of the Utility Model

[0013] Preferably, an adjusting seat is provided at the bottom of the support member.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] 1. The detachable connection method is adopted between the cross bar and the support member, which is convenient for transportation and handling. At the same time, after splicing, an integral connection structure is formed as a whole, which is more stable. At the same time, the connection with the bridge guardrail can be quickly completed by using the fixing member, and there is no need to drill holes anymore;

Specific embodiments

[0028] To make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present utility model.

[0029] Specific embodiment one: In combination with Figures 1-7 As shown, a temporary protection device for highway construction includes: a support member 1, at least two support members 1 are used, and they are arranged at intervals on the bridge enclosure, and are connected to the bridge guardrail through the fixing member 2 below the support member 1 to quickly complete the fixing of the support member 1 itself; a cross bar 3, both ends of the cross bar 3 are detachably connected to the support member 1, and the corresponding number of support members 1 are arranged according to needs, and the appropriate number of cross bars 3 are installed to quickly form a traditional support structure. At the same time, after splicing, relying on the connection at both ends of the cross bar 3, each support member 1 can be formed into an integral structure, which is more stable after installation. Then, a plurality of protective plates 4 are sequentially fixed on the cross bar 3 through bolts to form road protection; among them, two cross bars 3 are used and are arranged in an up-and-down form, which can effectively improve the stability of the protective plate 4 after installation. Three, four, etc. can also be used, which are determined according to needs.

[0030] Preferred embodiment, in combination with Figure 1 As shown, the fixing member 2 is a U-shaped hoop, and two nuts are installed on the U-shaped hoop. By rotating the nuts to drive the U-shaped hoop to tighten, the fixing with the bridge guardrail can be quickly completed.

[0031] Preferred embodiment, in combination with Figure 5 As shown, the fixing member 2 includes a pull rod 201 and a metal sheet 202; the pull rods 201 are arranged in pairs at both ends of the metal sheet 202, and the two are welded together. External threads are processed on the surface of the pull rod 201, and nuts are installed on the pull rod 201 at the same time. By tightening the nuts, the connection with the bridge guardrail is realized, and it can be adapted to connect with bridge guardrails of different diameters.

[0032] Preferred embodiment, in combination with Figure 2 and Figure 3As shown, a plurality of notches 101 are provided on the support member 1. The height of the notch 101 is equal to the height of the cross bar 3. At the same time, a positioning pin 5 that can slide upward is provided in the notch 101. Through holes 301 with the same diameter as the positioning pin 5 are machined at both ends of the cross bar 3. During splicing, by pushing the positioning pin 5 upward, and then putting the cross bar 3 into the notch 101, the positioning pin 5 is inserted into the through hole 301 under the action of gravity, and the connection and fixation of the cross bar 3 can be quickly completed. Among them, for the subsequent disassembly of the cross bar 3, in order to facilitate disassembly, a rectangular notch with a width smaller than the width of the support member 1 can be cut again above the notch 101, which is convenient for the staff to pull the positioning pin 5 upward to displace and pull out the positioning pin 5 from the through hole 301.

[0033] Preferred embodiment, combined with Figure 4 As shown, both sides of the cross brace plate 501 are fixedly welded to the support member 1. A circular hole is machined on the left side of the cross brace plate 501.

At the same time, the rotating shaft 103 is threadedly connected to the middle of the cross brace plate 501. By rotating the rotating shaft 103, the cross brace plate 501 can be pushed to slide in the sliding groove 102 to finely adjust the position of the positioning pin 5, reducing the requirement for installation accuracy and avoiding the positioning pin 5 being unable to be inserted into the through hole 301 of the cross bar 3 due to deviation in the installation position.

[0036] Preferred embodiment, combined with Figure 2 and Figure 3 As shown, an adjusting seat 104 is provided at the bottom of the support member 1. The adjusting seat 104 is threadedly connected to the bottom of the support member 1. By rotating the adjusting seat 104, the support member 1 can be pushed to rise, facilitating the connection between the fixing member 2 and the bridge guardrail and reducing the requirement for construction accuracy.

[0037] Preferred embodiment, combined with Figure 7 As shown, a plurality of mounting holes 301 are provided on the cross bar 3, and the connection with the protection plate 4 is realized by passing bolts through.

[0038] Preferred embodiment, combined withFigure 7 As shown, in order to improve the support strength between the two crossbars 3, vertical bars can be installed between the two crossbars 3, and the vertical bars and the crossbars 3 can be connected by screws. Specific Embodiment Two
