Description

Technical Field

[0001] The utility model belongs to the technical field of guardrails, and in particular relates to an assembled metal-based composite new material guardrail. Background Art

[0002] Metal matrix composites are composite materials that are artificially combined with metals and their alloys as the matrix and one or more metal or non-metal reinforcements. Most of the reinforcement materials are inorganic non-metals, such as ceramics, carbon, graphite and boron, etc. Metal wire can also be used. Guardrails are a safety measure that can effectively reduce casualties when an accident occurs. In order to improve the performance defects of traditional wood, steel and concrete guardrails and improve the safety level of highway guardrails, highway guardrails made of metal matrix composite materials are an important solution.

[0003] The metal-based composite new material guardrails of the existing technology usually weld the horizontal bars and vertical bars together. When the guardrail is impacted and the horizontal bars or vertical bars are deformed and broken, the entire guardrail needs to be disassembled and replaced. The horizontal bars or vertical bars cannot be disassembled and assembled separately, which wastes too much material and increases the cost of using the guardrail. Utility Model Content

[0004] The purpose of the utility model is to provide an assembled metal-based composite new material guardrail. After the guardrail is subjected to external impact, the horizontal bars and vertical bars of the guardrail can be disassembled and assembled separately more conveniently, without the need to dismantle and replace the entire guardrail. The replacement and maintenance work can be completed at a relatively low cost, saving materials required for maintenance.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An assembled metal-based composite new material guardrail includes a column and a cross bar, wherein both ends of the column are symmetrically provided with inner grooves, a sliding groove is penetrated through one side of the inner groove, one end of the cross bar is fixedly connected with an insert plate, the cross bar is arranged in two symmetrical configurations, a vertical bar is equidistantly and movably inserted between the two cross bars, both ends of the vertical bar are fixedly connected with gusset plates, an embedding rod is fixedly connected to the middle of the gusset plates, an outer wall of the cross bar is equidistantly provided with buckle grooves, and the middle of the buckle grooves is provided with an embedding hole for the embedding rod to be embedded and engaged.

[0007] A U-shaped connecting piece is fixedly connected to one side of the inner wall of the inner groove.

[0008] One side of the U-shaped connecting piece is rotatably connected with a rotating plate, and the rotating plate is arranged in a shape of a letter with different sizes at both ends.

[0009] The inlay plate passes through the sliding groove and is movably plugged into the rotating plate. The inlay plate and the rotating plate are detachably fixed to the interior of the inner groove by fixing screws.

[0010] A sealing plate is rotatably connected to the outer wall of the column and located at one side of the inner groove, and the sealing plate is detachably connected to the column through screws.

[0011] The technical effect achieved by the utility model is that after the guardrail suffers an external impact, the horizontal bars and vertical bars of the guardrail can be disassembled and assembled separately more conveniently, without the need to dismantle and replace the entire guardrail. The replacement and maintenance work can be completed at a relatively low cost, saving materials required for maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] In order to make the purpose and advantages of the utility model more clear, the utility model is specifically described in combination with the following embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the utility model, and does not strictly limit the protection scope of the specific request of the utility model.

[0019] like Figure 1-2As shown, an assembled metal-based composite new material guardrail includes a column 1 and a cross bar 107. Inner grooves 101 are symmetrically opened at both ends of the column 1. A sealing plate 102 is rotatably connected to the outer wall of the column 1 and located on one side of the inner groove 101. The sealing plate 102 is detachably connected to the column 1 through a screw 103. A sliding groove 106 is penetrated through one side of the inner groove 101. A U-shaped connector 104 is fixedly connected to one side of the inner wall of the inner groove 101. A rotating plate 105 is rotatably connected to one side of the U-shaped connector 104. The rotating plate 105 is set to an 8-shape with different sizes at both ends. An inlay plate 108 is fixedly connected to one end of the cross bar 107. The inlay plate 108 passes through the sliding groove 106 and is movably connected to the rotating plate 105. The inlay plate 108 and the rotating plate 105 are detachably fixed to the inside of the inner groove 101 through a fixing screw 111.

[0020] According to the above structure, the fixing of the sealing plate 102 and the column 1 is released by loosening the disassembly screw 103, and the interior of the inner groove 101 can be operated by rotating the sealing plate 102. The fixing screw 111 is rotated to release the fixing relationship between the inlay panel 108 and the rotating plate 105. The rotating plate 105 is turned to one side of the U-shaped connecting piece 104, and the cross bar 107 is lifted up. The cross bar 107 slides in the sliding groove 106, and the inlay panel 108 moves accordingly. At this time, the cross bar 107 is moved to one side, and the cross bar 107 can be tilted and taken out through the sliding groove 106.

[0021] See attached Figure 3-4 The cross bars 107 are arranged to be symmetrical, and a vertical bar 109 is equidistantly and movably inserted between the two cross bars 107. Both ends of the vertical bar 109 are fixedly connected with buckle plates 110, and the middle of the buckle plates 110 is fixedly connected with an embedded rod 113. Buckle grooves 112 are equidistantly provided on the outer wall of the cross bar 107, and an embedding hole 114 for the embedded rod 113 to be embedded and engaged is provided in the middle of the buckle grooves 112.

[0022] According to the above structure, when the cross bar 107 moves upward, the embedding hole 114 disengages from the embedding bar 113, and the buckle groove 112 is also separated from the buckle plate 110, so that the vertical bar 109 can be removed separately; after the guardrail is subjected to external impact, the utility model can more conveniently disassemble and assemble the cross bar 107 and the vertical bar 109 of the guardrail separately, without the need to dismantle and replace the entire guardrail. The replacement and maintenance work can be completed at a relatively low cost, saving the materials required for maintenance.

[0023] The working principle of the utility model is as follows: by loosening the disassembly screw 103, the fixing of the sealing plate 102 and the column 1 is released, and the sealing plate 102 is rotated to operate the inside of the inner groove 101, and the fixing screw 111 is rotated to release the fixing relationship between the inlay plate 108 and the rotating plate 105, and the rotating plate 105 is turned to one side of the U-shaped connecting piece 104, and the cross bar 107 is lifted up, and the cross bar 107 slides in the sliding groove 106, and the inlay plate 108 moves accordingly. At this time, the cross bar 107 is moved to one side, and the cross bar 107 can be tilted and taken out through the sliding groove 106; when the cross bar 107 moves upward, the embedding hole 114 is separated from the embedding rod 113, and the buckle groove 112 is also separated from the buckle plate 110, so that the vertical rod 109 can be removed separately.

[0024] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
