[0024] like Figures 1-5As shown, this utility model provides a barrier for closure of bridge lanes, including a rectangular frame 2, a lower connecting unit and an upper connecting unit. The lower connecting unit includes two connecting strips 6. Each connecting strip 6 has an L-shaped L-plate 6-1 at one end of its bottom. The L-plate 6-1 can be placed on the bottom crossbar of the rectangular frame 2. The side of the L-plate 6-1 has a third elongated hole 6-2. The side of the bottom crossbar of the rectangular frame 2 has a second threaded hole 2-5 corresponding to the third elongated hole 6-2. The L-plate 6-1 and the bottom crossbar of the rectangular frame 2 are fixed together by a third connecting bolt 6-3 passing through the third elongated hole 6-2 and the second threaded hole 2-5.

[0025] The upper connecting unit includes a sliding rod 3 and a snap-fit ​​cover 3-4. The sliding rod 3 has two sliding sleeves 3-2 at both ends. The sliding sleeves 3-2 are slidably fitted onto the two longitudinal rods of the rectangular frame 2. The bottom of the snap-fit ​​cover 3-4 has a through groove adapted to the top of the cement isolation block 1. The top of the cement isolation block 1 can extend into the through groove. The top of the snap-fit ​​cover 3-4 has a connecting rod 3-3. One end of the connecting rod 3-3 is fixed to one side of the sliding rod 3. One side of the sliding sleeve 3-2 has a second elongated hole 3-2-1. The longitudinal rods of the rectangular frame 2 have a first threaded hole 2-4 corresponding to the second elongated hole 3-2-1. The sliding sleeve 3-2 and the longitudinal rods of the rectangular frame 2 are fixed by a second connecting bolt 3-2-2 passing through the second elongated hole 3-2-1 and the first threaded hole 2-4.

[0026] The upper part of the rectangular frame 2 has a baffle, which is located above the slide bar 3.

[0027] When using the above structure, a forklift is used to place the cement isolation block 1 at the layout position. For each cement isolation block 1, first place the rectangular frame 2 on the side of the cement isolation block 1 facing the construction site, and insert the connecting strip 6 into the rectangular groove 1-1 at the bottom of the cement isolation block 1. This rectangular groove 1-1 is generally used to facilitate the handling of the cement block. After the connecting strip 6 is inserted, the L-plate 6-1 on the connecting strip 6 is fixed to the bottom crossbar of the rectangular frame 2 by the third connecting bolt 6-3. The setting of the third elongated hole 6-2 facilitates the adjustment of the fixing position of the L-plate 6-1. Then, the sliding sleeve 3- is adjusted. 2. Position the top of the cement isolation block 1 on the longitudinal rod of the rectangular frame 2 so that it extends into the through groove of the snap-fit ​​cover 3-4. Fix the sliding rod 3 to the rectangular frame 2 by the second connecting bolt 3-2-2. At this time, the rectangular frame 2 and the cement isolation block 1 are fixed by the fixing of the connecting strip 6 and the snap-fit ​​cover 3-4. This fixing method does not cause any damage or change to the structure of the cement isolation block 1, and the installation method is simple and convenient, which facilitates the repeated use of the fence. The lower part of the fence forms a barrier between the construction area and the non-construction area of ​​the bridge deck through the cement isolation block 1, and the upper part forms a closed barrier through the baffle.

[0028] like Figure 6 , Figure 7As shown, in order to connect the barriers on each cement isolation block 1 into a whole and provide overall stability, a U-shaped side connecting plate 2-3 is also designed on the rectangular frame 2. The U-shaped side connecting plate 2-3 is located at one end of the upper crossbeam of the rectangular frame 2. Both sides of one end of the upper crossbeam of the rectangular frame 2 have limiting posts 2-3-2. Both sides of the U-shaped side connecting plate 2-3 have side sliding holes 2-3-1 corresponding to the limiting posts 2-3-2. The limiting posts 2-3-2 pass through the side sliding holes 2-3-1 and are slidably connected to the side sliding holes 2-3-1. The top of the U-shaped side connecting plate 2-3 has a first elongated hole 2-3-3. The top surface of the other end of the upper crossbeam of the rectangular frame 2 has a fourth threaded hole 2-6.

[0029] like Figure 6 , Figure 7 As shown, adjacent fences are connected by a U-shaped side connecting plate 2-3 on the rectangular frame 2 of one fence and a fourth threaded hole 2-6 on the rectangular frame 2 of another fence via a first connecting bolt 2-3-4.

[0030] The rectangular frame 2 has a fixed crossbeam 2-1 in the middle, which is located below the sliding rod 3. There is an isolation net 4 between the fixed crossbeam 2-1 and the bottom crossbar of the rectangular frame 2. The isolation net 4 protects the cement isolation block 1 and prevents sand and gravel from splashing during construction from damaging the cement isolation block 1.

[0031] To facilitate transportation and processing, the baffle and rectangular frame 2 can be configured as a detachable structure. The baffle has pins near its two sides, and the inner wall of the rectangular frame 2 has holes corresponding to the pins.

[0032] This embodiment also provides another connection structure for the baffle, which is a plug-in baffle 5. The top surface of the slide rod 3 has a slot 3-1 corresponding to the lower edge of the plug-in baffle 5. The upper crossbeam of the rectangular frame 2 has a rectangular socket 2-2 corresponding to the slot 3-1. The plug-in baffle 5 can be inserted into the rectangular frame 2 through the rectangular socket 2-2.

[0033] To prevent collisions between the end of the connecting strip 6 on the unconstructed side and vehicles, the lower connecting unit also includes a limiting block 7 corresponding to each connecting strip 6. One side of the limiting block 7 has a groove 7-2 that penetrates the bottom of the limiting block 7. The other end of the connecting strip 6 can extend into the slot 3-1. The top surface of the limiting block 7 has a fourth elongated hole 7-1, and the upper surface of the connecting strip 6 has a third threaded hole 6-4 corresponding to the fourth elongated hole 7-1. The limiting block 7 and the connecting strip 6 are fixed together by a fourth connecting bolt 7-3 passing through the fourth elongated hole 7-1 and the third threaded hole 6-4. One side of the limiting block 7 can contact the side of the cement barrier 1, thus limiting the movement of the cement barrier 7. The outer edge of the limiting block 7 has a rounded chamfer. A rubber protective layer is attached to the outer surface of the limiting block 7.

[0034] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
