Description

Technical Field

[0001] This utility model relates to the field of post-cast strip technology, and more specifically, to a horizontal post-cast strip intercepting rebar support. Background Technology

[0002] Post-cast strips are temporary construction joints left at corresponding positions in foundation slabs, walls, and beams during building construction to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven temperature and shrinkage, in accordance with design or construction specifications.

[0003] During the pouring process on both sides of the post-pouring strip, isolation plates are installed on both sides of the post-pouring strip to block the concrete poured on both sides and prevent it from flowing into the post-pouring strip. However, the existing isolation plates adhere to the concrete, causing them to stick together. Also, because the isolation plates are a single unit, it is difficult to apply force to the entire plate when applying force, making it difficult to remove them and preventing the isolation plates from being recycled and reused. Utility Model Content

[0004] The purpose of this utility model is to provide a horizontal post-cast strip intercepting steel bar support, which solves the problem that the isolation plate installed in the post-cast strip is too long and therefore separates from the concrete, making it impossible to recycle and reuse the isolation plate.

[0005] This utility model is achieved through the following technical solution: This utility model provides a horizontal post-cast strip intercepting rebar support, including a road surface, a post-cast strip in the middle of the road surface, a lower layer of rebar at the top of the road surface, several isolation plates at the top of the lower layer of rebar, a water-stop steel plate connected in the middle of the isolation plates, an upper layer of rebar connected at the top of the water-stop steel plate, interlocking blocks on both sides of the isolation plates, interlocking openings on both sides of the isolation plates, several isolation plates are connected in a staggered manner through the interlocking blocks and interlocking openings on both sides, a separation shaft is connected in the middle of the interlocking blocks, and a lifting groove is provided at the top of the interlocking opening.

[0006] Preferably, the water-stop steel plate is connected between the upper and lower isolation plates, and the isolation plates are connected to the top two sides of the post-pouring strip.

[0007] Preferably, the interlocking block further includes a through hole, a rotating ring, a deflecting disk, and a deflecting rod. The through hole is located in the middle of the interlocking block, the rotating ring is connected to the inner wall of the middle of the through hole, the deflecting disk is located on both sides of the inner wall of the rotating ring, and the deflecting rod is located on one side of the deflecting disk.

[0008] Preferably, the inner diameter of the through hole is larger than the diameter of the separation shaft, and the separation shaft passes through the through hole to engage with the lifting groove.

[0009] Preferably, the rotating ring is a circular ring connected to an annular groove on the inner wall of the through hole.

[0010] Preferably, the deflection disks are also disposed on both sides of the separation shaft, and the deflection disks are rotatably connected to the inner wall of the rotating ring and the side wall of the separation shaft.

[0011] Preferably, a deflection rod is connected between the inner wall of the rotating ring and the deflection disk on the side wall of the separation shaft, and the deflection rod is telescopic.

[0012] Preferably, the bottom sidewall of the separating shaft is threaded to the inner wall of the lifting groove, and the length of the mating block is less than the length of the mating opening.

[0013] The technical solution of this utility model has at least the following advantages and beneficial effects: 1. Through the cooperation of the interlocking block and the interlocking opening in the device, the individual isolation plate can be lifted by controlling the rotation of the separation shaft, thereby actively separating it from the concrete layer, and avoiding the difficulty of separation and recycling due to the lack of a force application point.

[0014] 2. The device is also equipped with a deflector. The deflector can work with the isolation plate to prevent tilting during separation, so as not to affect the rotation and lifting of the separation shaft. It also makes it convenient to control the rotation, lifting and separation of the two separation shafts at the same time. Attached Figure Description

Detailed Implementation

[0020] The following is combined with Figures 1 to 4 This utility model will be described in detail.

[0021] A horizontal post-cast strip intercepting rebar support includes a road surface 1, a post-cast strip 101 in the middle of the road surface 1, a lower layer of rebar 2 at the top of the road surface 1, several isolation plates 4 at the top of the lower layer of rebar 2, a water-stop steel plate 5 connected to the middle of the isolation plate 4, an upper layer of rebar 3 connected to the top of the water-stop steel plate 5, interlocking blocks 402 on both sides of the isolation plate 4, interlocking openings 403 on both sides of the isolation plate 4, several isolation plates 4 are connected by interlocking blocks 402 and interlocking openings 403 in a staggered arrangement, a separation shaft 401 is connected to the middle of the interlocking block 402, a lifting groove 4031 is provided at the top of the interlocking opening 403, the water-stop steel plate 5 is connected between the upper and lower isolation plates 4, and the isolation plates 4 are connected to the top two sides of the post-cast strip 101.

[0022] First, after the road surface 1 is poured, isolation plates 4 are installed on both sides of the top of the reserved post-pouring strip 101. The isolation plates 4 are built between the lower layer of steel bars 2 and the upper layer of steel bars 3, so that the post-pouring strip 101 will be isolated when the top of the road surface 1 is poured, so that the post-pouring strip 101 will not be affected during the pouring process. Finally, the post-pouring strip 101 is poured.

[0023] Furthermore, the mating block 402 also includes a through hole 4021, a rotating ring 4022, a deflecting disk 4023, and a deflecting rod 4024. The through hole 4021 is located in the middle of the mating block 402. The rotating ring 4022 is connected to the inner wall of the middle part of the through hole 4021. The deflecting disk 4023 is located on both sides of the inner wall of the rotating ring 4022. The deflecting rod 4024 is located on one side of the deflecting disk 4023. The inner diameter of the through hole 4021 is larger than the diameter of the separating shaft 401. The separating shaft 401 passes through the through hole 4021 to cooperate with the lifting groove 4031. The rotating ring 4022 is a circular ring connected to the annular groove on the inner wall of the through hole 4021. The deflection disk 4023 is also provided on both sides of the separation shaft 401. The deflection disk 4023 is rotatably connected to the inner wall of the rotating ring 4022 and the side wall of the separation shaft 401. A deflection rod 4024 is connected between the inner wall of the rotating ring 4022 and the deflection disk 4023 on the side wall of the separation shaft 401. The deflection rod 4024 is telescopic. The bottom side wall of the separation shaft 401 is threadedly matched with the inner wall of the lifting groove 4031. The length of the fitting block 402 is less than the length of the fitting opening 403.

[0024] After the concrete pouring above the road surface 1 is completed, the separation shaft 401 on one side of the interlocking block 402 of the isolation plate 4 can be rotated by controlling the separation shaft 401. When the separation shaft 401 rotates, its bottom thread matches the lifting groove 4031, causing the separation shaft 401 to rise during rotation. The side wall of the separation shaft 401 is connected to the rotating ring 4022 through the through hole 4021, so that when the separation shaft 401 rotates and rises, it will drive the rotating ring 4022 to rise as well. The rotating ring 4022 is connected to the annular groove on the inner wall of the through hole 4021, so that when the rotating ring 4022 rises, it will drive the fitting block 402 to rise, thereby causing one side of the isolation plate 4 to rise and separate from the poured concrete without manual pulling. Because the length of the fitting block 402 is less than the length of the fitting opening 403, a gap will be left between one end of the fitting block 402 and the fitting opening 403, so that the fitting block 402 has room to change its angle when it rises and tilts.

[0025] Simultaneously, when one side of the isolation plate 4 tilts, the through hole 4021 connecting the separation shaft 401 on the other side will cooperate with the deflection disk 4023 on the inner wall of the separation shaft 401 through the deflection disk 4023 on the side wall. The rotation of the two deflection disks 4023 ensures that the through hole 4021 will not affect the separation shaft 401 when it tilts, allowing the separation shaft 401 to continue to rotate and lift normally. The deflection rods that are telescopically installed between the deflection disks 4023 also maintain the connection between the separation shaft 401 and the deflection disks 4023. When the separation shaft 401 is rotated in the tilted state, the isolation plate 4 will still be lifted to separate it. This will prevent the isolation plate 4 from being difficult to separate and recycle due to the lack of a force point attached to the concrete. After removing the two isolation plates 4 with interlocking blocks 402, the two sides of the isolation plate 4 with the interlocking opening 403 will be exposed to facilitate separation and recycling. The segmented isolation plate 4 can also be used to accommodate post-pouring strips 101 of different lengths. The water-stop steel plate 5 will remain in the concrete to stop water.

[0026] The following is a detailed implementation process of this utility model. First, after the road surface 1 is poured, isolation plates 4 are installed on both sides of the top of the reserved post-pouring strip 101. The isolation plates 4 are built between the lower layer of steel bars 2 and the upper layer of steel bars 3, so that the post-pouring strip 101 is isolated when the top of the road surface 1 is poured, so that the post-pouring strip 101 is not affected during the pouring process. Then, after the post-pouring strip 101 is poured, after the isolation plates 4 have finished pouring above the road surface 1, the separation shaft 401 on the interlocking block 402 on one side of one of the isolation plates 4 can be rotated. When the separation shaft 401 rotates, because its bottom... The threaded connection with the lifting groove 4031 allows the separating shaft 401 to rise during rotation. The side wall of the separating shaft 401 passes through the through hole 4021 and connects to the rotating ring 4022. As the separating shaft 401 rises, it drives the rotating ring 4022 to rise as well. Simultaneously, the rotating ring 4022 is connected to an annular groove on the inner wall of the through hole 4021. This causes the rotating ring 4022 to rise, pulling the interlocking block 402 upwards, thereby causing one side of the isolation plate 4 to rise and separate from the poured concrete without manual pulling. This is because the interlocking block 402 is shorter. The length of the fitting opening 403 leaves a gap between one end of the fitting block 402 and the fitting opening 403, allowing the fitting block 402 room to change its angle when it rises and tilts. Simultaneously, when one side of the partition plate 4 tilts, the through hole 4021 connecting the separation shaft 401 on the other side engages with the deflector 4023 on the inner wall of the separation shaft 401 via the deflector 4023 on the side wall. The rotation of the two deflector 4023 ensures that the through hole 4021 does not affect the separation shaft 401 when it tilts, allowing the separation shaft 401 to continue rotating and lifting normally. The deflector 4023... The deflection rods that are telescopically connected between the two sides can also maintain the connection between the separation shaft 401 and the deflection disk 4023, so that when the separation shaft 401 rotates in the tilted state, it will still lift the isolation plate 4, thereby lifting and separating the isolation plate 4, so as not to be difficult to separate and recycle because it is attached to the concrete without a force point. At the same time, after removing the two isolation plates 4 with the interlocking blocks 402, the two sides of the isolation plate 4 with the interlocking opening 403 between them will be exposed, so as to facilitate separation and recycling. The segmented isolation plate 4 can also be used to accommodate post-pouring strips 101 of different lengths. The water-stop steel plate 5 will remain in the concrete to stop water.
