Description

Technical Field

[0001] This utility model belongs to the field of subway construction technology, specifically relating to a protective baffle. Background Technology

[0002] During subway construction, workers operate on the enclosed subway tracks. Protective barriers are installed on the subway platforms to protect personnel and the area. Currently, these barriers stand in rows on the platforms, with supports between adjacent barriers. The barriers are secured to the supports with bolts, and the supports are also secured to the platform with bolts at their bases. This keeps the rows of barriers connected and fixed in their designated positions. However, during protection, if one barrier is impacted, it can cause multiple connected barriers to be impacted simultaneously, leading to shaking, displacement, deformation, and damage. This makes it difficult to effectively disconnect the connected barriers in a timely manner, affecting the overall protective effect. Utility Model Content

[0003] This utility model provides a protective baffle that improves the protective effect.

[0004] This utility model provides the following technical solution: it includes a construction enclosure and a fixing component. The fixing component includes a fixing frame and a crossbar. There are two fixing frames and two crossbars. The two crossbars are screwed one above the other between the two fixing frames. The construction enclosure is located behind the crossbars. Two splicing components corresponding to the crossbars are provided in front of the construction enclosure. The splicing components include a clamping frame and a connecting adhesive post. The clamping frame is clamped and positioned on the front of the construction enclosure by the connecting adhesive post, and clamps the corresponding crossbar from the outside.

[0005] The two ends of the crossbar are respectively attached to the outer walls of the two fixing frames. The outer walls of the fixing frames are screwed with two fixing screws corresponding to the crossbar. The fixing screws are screwed to the corresponding ends of the crossbar, and the fixing frames are screwed to the construction ground.

[0006] The crossbar has several rubber wedges that are equidistantly distributed in a straight line on its outer wall. The construction fence has through grooves corresponding to the rubber wedges, and the rubber wedges are slidably connected inside the corresponding through grooves.

[0007] The rubber wedge is positioned at a height higher than the through groove at both ends, and is engaged between two adjacent construction barriers.

[0008] The card frame has several linearly distributed connecting rubber columns fixedly connected to its horizontal and vertical ends. The construction fence has corresponding insertion holes for the connecting rubber columns, and the connecting rubber columns are inserted into the corresponding insertion holes.

[0009] The card frame is located in the left half of the front of the construction fence, and both the horizontal and vertical ends of the card frame are close to the front of the construction fence.

[0010] The bottom of the construction enclosure is higher than the bottom of the fixing frame.

[0011] The beneficial effects of this utility model are:

[0012] 1. This utility model features a separate construction fence and fixing components. Two fixing frames are fixed to the ground, and two horizontal bars are fixed by fixing screws, one above the other. The construction fence can move laterally behind the two horizontal bars. The construction fence is positioned by rubber wedges on both sides. The splicing components are inserted into the front of the construction fence, and the clamping frame clamps the horizontal bars from the outside to position the construction fence. The operation is simple, which facilitates the adjustment and positioning of the construction fence between the two fixing frames, and improves the installation and positioning efficiency of the construction fence.

[0013] 2. In this utility model, when the construction fence is subjected to a frontal impact, the connecting rubber column inserted into the front of the construction fence on the card frame can detach from the construction fence, so that the card frame and the crossbar are separated from the construction fence, allowing the construction fence to form and maintain an independent state. This can effectively and timely disconnect and separate the corresponding construction fence, ensuring that the remaining construction fences are not affected by the impact, allowing the remaining construction fences to continue to perform stable protective operations. At the same time, it can facilitate the replacement of individual construction fences, improving the protective effect.

[0014] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0020] Please see Figures 1-4 The present invention provides the following technical solution: it includes a construction enclosure 1 and a fixing component 2. The fixing component 2 includes a fixing frame 21 and a crossbar 22. There are two fixing frames 21 and two crossbars 22. The two crossbars 22 are screwed one above the other between the two fixing frames 21. The construction enclosure 1 is located behind the crossbars 22. There are two splicing components 3 corresponding to the crossbars 22 in front of the construction enclosure 1. The splicing components 3 include a clamping frame 31 and a connecting glue column 32. The clamping frame 31 is clamped and positioned on the front of the construction enclosure 1 by the connecting glue column 32, and clamps the corresponding crossbar 22 from the outside.

[0021] In this implementation scheme: the fixing component 2 is used to connect the construction enclosure 1. The fixing component 2 consists of a fixing frame 21 and two crossbars 22. Two crossbars 22 are placed horizontally between the two fixing frames 21, one above the other. The two ends of the crossbars 22 are respectively attached to the outer walls of the two fixing frames 21. Two fixing screws 23 corresponding to the crossbars 22 are screwed onto the outer wall of the fixing frame 21. The fixing screws 23 are screwed and fixed to the corresponding ends of the crossbars 22, facilitating the connection and fixing of the two fixing frames 21 and the two crossbars 22. The fixing frame 21 is screwed and fixed to the construction ground to facilitate the installation and fixing of the entire fixing component 2 within the construction protection area.

[0022] The construction enclosure 1 is located behind the horizontal bar 22. Several rubber wedges 221, evenly spaced in a straight line, are fixedly connected to the outer wall of the horizontal bar 22. The construction enclosure 1 has corresponding through slots 11 on the rubber wedges 221. The rubber wedges 221 are slidably connected inside the corresponding through slots 11, allowing the construction enclosure 1 to move along the long side of the horizontal bar 22 behind it, facilitating position adjustment within the construction protection area. The front and rear ends of the rubber wedges 221 are both higher than the through slots 11, allowing the front end of the rubber wedges 221 to first enter the through slots 11. As the rubber wedges 221 continue to move into the through slots 11, their rear ends are forced into the through slots 11. The movement of the rubber wedges 221 along the slot wall improves the stability of the construction enclosure 1 when moving outside the horizontal bar 22. The construction enclosure 1 moves outside the horizontal bar 22, causing the rubber wedge 221 to gradually move from inside the through groove 11 to outside the through groove 11. The rubber wedge 221 that moves out of the through groove 11 can engage and connect between two adjacent construction enclosures 1. Both sides of the construction enclosure 1 are pressed against a rubber wedge 221, which can effectively position the construction enclosure 1 after it moves.

[0023] Two splicing components 3, one above the other, are installed at the front of the construction enclosure 1. Each splicing component 3 corresponds to one of the two horizontal bars 22. Each splicing component 3 consists of a frame 31 and connecting posts 32. Several linearly distributed connecting posts 32 are fixedly connected to both the horizontal and vertical ends of the frame 31, stably connecting the frame 31 and the posts 32. The construction enclosure 1 has corresponding insertion holes 12 for the connecting posts 32. The connecting posts 32 are inserted into the corresponding holes 12, allowing the frame 31 to be securely positioned on the front of the construction enclosure 1 by the connecting posts 32. The frame 31 is located in the left half of the front of the construction enclosure 1, with both its horizontal and vertical ends pressed against the front of the enclosure. The horizontal bars 22 are engaged between the frame 31 and the construction enclosure 1, allowing the frame 31 to engage the corresponding horizontal bars 22 from the outside, effectively combining the construction enclosure 1, the fixing component 2, and the splicing component 3.

[0024] The construction enclosure 1 and the fixing component 2 adopt a combined design. Two fixing frames 21 are fixed to the ground, and two horizontal bars 22 are positioned vertically between the two fixing frames 21. The two horizontal bars 22 are fixed between the two fixing frames 21 by fixing screws 23 at corresponding positions on the fixing frames 21. The horizontal bars 22 are used to connect the construction enclosure 1, and multiple construction enclosures 1 can be connected laterally on the two horizontal bars 22 to increase the protection range. The construction fence 1 moves laterally behind the two horizontal bars 22. The construction fence 1, adjusted to the designated position, is positioned by rubber wedges 221 on both sides. By connecting the splicing component 3 to the front of the positioned construction fence 1, the clamping frame 31 moves closer to the front of the construction fence 1. Several connecting rubber posts 32 are inserted into the corresponding insertion holes 12 on the front of the construction fence 1. Through the deformation and expansion of the connecting rubber posts 32, the clamping frame 31 is clamped to the front of the construction fence 1, so that the clamping frame 31 clamps the horizontal bars 22 on the front of the construction fence 1 from the outside, thereby effectively positioning the construction fence 1. The operation is simple, which facilitates the adjustment and positioning of the construction fence 1 between the two fixed frames 21, and improves the installation and positioning efficiency of the construction fence 1. The bottom of the construction fence 1 is higher than the bottom of the fixing frame 21. When the construction fence 1 is subjected to a frontal impact, the connecting rubber post 32 inserted into the front of the construction fence 1 on the clip frame 31 can be detached from the construction fence 1, so that the clip frame 31 and the crossbar 22 are separated from the construction fence 1, allowing the construction fence 1 to form and remain in an independent state. This can effectively and timely disconnect and separate the corresponding construction fence 1, ensuring that the other construction fences 1 are not affected by the impact, allowing the other construction fences 1 to continue to carry out stable protection operations. At the same time, it can facilitate the replacement of a single construction fence 1, improving the protection effect.
