Description

Technical Field

[0001] This utility model relates to the field of building construction technology; specifically, this utility model relates to a separation device for the joint of concrete of different grades used in building construction. Background Technology

[0002] Concrete is a general term for engineering composite materials that bind aggregates together with cementing materials. The term "concrete" usually refers to cement concrete, also known as ordinary concrete, which is made by mixing cement as the cementing material, sand and gravel as aggregates, and water (which may contain admixtures and additives) in a certain proportion. It is widely used in civil engineering. To address the issue of separating concrete of different strength grades (such as waterproof and non-waterproof) for interior and exterior walls, and for walls, columns, beams, and slabs, concrete separation devices are needed.

[0003] Application No. 202322840730.X discloses a device for separating concrete of different grades, relating to the technical field of concrete pouring auxiliary tools. It includes a counterweight beam, a separating tube assembly hung below the counterweight beam for separating concrete of different grades, and a fixed bracket for positioning the separating tube assembly. The fixed bracket is detachably mounted on the counterweight beam. A lifting component is provided at the top of the separating tube assembly for easy removal after concrete pouring. This utility model has a reasonable design. The separating tube assembly mainly functions to separate concrete of different grades, avoiding excessive consumption of high-grade concrete and saving costs. The counterweight beam provides reaction support, mainly preventing the separating tube assembly from floating during concrete pouring, improving the overall stability of the device, and preventing lower displacement. It can utilize locally sourced materials and waste materials, and has advantages such as high rigidity, light weight, simple manufacturing, and reusability.

[0004] However, in actual use, the above technology lacks the locking mechanism for the partition pipe assembly, which makes it easy for the partition pipe assembly to shake during concrete pouring. This causes the gap between the two sets of partition pipe assemblies to widen during pouring, resulting in concrete slurry retention. At the same time, when the partition pipe assembly does not shake, the excessive gap between the two sets of partition pipes makes the concrete blocking effect poor. Utility Model Content

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] like Figures 1 to 3As shown, a typical embodiment of this utility model provides a separation device for the joint of concrete of different grades used in building construction, including: a stop bar 1, a suspension bar 2, and a suspension assembly 3; the suspension assembly 3 includes a suspension plate 3-1 and bolts 3-3. The suspension plate 3-1 is L-shaped, and an arc-shaped suspension buckle 3-2 is fixedly installed on the side of the suspension plate 3-1. The suspension buckle 3-2 is slidably installed on the suspension bar 2. The bolts 3-3 are threadedly connected to the top of the suspension plate 3-1. There are multiple stop bars 1, and multiple stop bars 1 are slidably installed on the suspension plate 3-1. The stop bars 1 can be inserted into the gap of the reinforcing bars. The suspension bar 2 is placed on the top surface of the reinforcing bars.

[0020] In use, the suspension buckle 3-2 is slidably installed on the suspension rod 2, so that multiple sets of stop rods 1 can be slidably installed on the suspension rod 2. After the stop rods 1 are installed, the stop rods 1 are inserted into the gaps of the reinforcing bars, and the bottom end of the suspension plate 3-1 is in contact with the transverse reinforcing bars. The suspension rod 2 is blocked by the reinforcing bars, which allows the stop rods 1 to be stably installed in the reinforcing bars. By rotating the bolts 3-3, each stop rod 1 can be stably installed in the reinforcing bars.

[0021] The bottom end of the suspension plate 3-1 is provided with a cavity 3-11, the top end of the stop rod 1 is fixedly installed with a connecting rod 1-1, the suspension plate 3-1 is slidably installed on the connecting rod 1-1, and a spring 3-12 is fixedly installed on the inner end face of the suspension plate 3-1 and the outer surface of the connecting rod 1-1.

[0022] When the connecting rod 1-1 slides on the suspension plate 3-1, it can drive the stop rod 1 to move, and at the same time compress the spring 3-12 and contact the transverse steel bar. When the spring 3-12 is no longer under force, the spring 3-12 returns to its original position, so that the connecting rod 1-1 can return to its original position.

[0023] A push block 4 is slidably installed inside the cavity 3-11. The left side of the push block 4 can contact the outer surface of the connecting rod 1-1, and the top right side of the push block 4 has an inclined surface 4-1.

[0024] When the pusher block 4 moves, it can drive the connecting rod 1-1 to move, and make the connecting rod 1-1 contact the transverse steel bar. The connecting rod 1-1 is held inside the steel bar by the transverse steel bar and the pusher plate, so that the stop rod 1 can be stably installed inside the steel bar.

[0025] The suspension plate 3-1 has an inclined block 4-2 in the longitudinal direction. The inclined side of the inclined block 4-2 contacts the inclined surface 4-1 of the push block 4, the flat surface of the inclined block 4-2 contacts the inner wall of the suspension plate 3-1, and the bottom end of the bolt 3-3 is rotatably connected to the top end of the suspension plate 3-1.

[0026] When the bolt 3-3 is rotated, the inclined block 4-2 can slide on the suspension plate 3-1. When the inclined block 4-2 moves downward, the inclined side can contact the inclined surface 4-1, and the push block 4 is pressed towards the connecting rod 1-1, and the connecting rod 1-1 is fixedly installed in the steel bar.

[0027] A first fixing plate 3-13 is fixedly installed on the left side of the suspension plate 3-1, and a second fixing plate 3-14 is fixedly installed on the right side of the suspension plate 3-1. A first moving plate 4-3 is fixedly installed on the left side of the push block 4, and a second moving plate 4-4 is fixedly installed on the right side of the push block 4. The first moving plate 4-3 and the first fixing plate 3-13 are positioned between the second moving plate 4-4 and the second fixing plate 3-14.

[0028] Contact heads 7 are fixedly installed at the ends of the first fixed plate 3-13 and the first movable plate 4-3. Support plates 5 are fixedly installed on the bottom surfaces of the second fixed plate 3-14 and the second movable plate 4-4. Guide blocks 6 are fixedly installed on the end faces of the second fixed plate 3-14 and the second movable plate 4-4.

[0029] When the first set of stop bars 1 is fixedly installed on the reinforcing bar, the distance between the second fixed plate 3-14 and the second movable plate 4-4 on the first set of stop bars 1 is restricted. The first fixed plate 3-13 and the first movable plate 4-3 on the second set of stop bars 1 are placed inside the second fixed plate 3-14 and the second movable plate 4-4 on the first set of stop bars 1. The second set of bolts 3-3 is rotated, causing the second set of inclined blocks 4-2 to move downward, causing the first movable plate 4-3 of the second set to shift, so that the contact head 7 contacts the guide block 6. The bolts 3-3 are rotated further, and the guide block 6 restricts the movement of the contact head 7 of the first movable plate 4-3 on the guide block 6, causing the second set of stop bars 1 to move towards the first set of stop bars 1. The support plate 5 is used to keep the stop bars 1 at the same height and lock the multiple sets of stop bars 1.

[0030] At this point, the stop bars 1 are in contact with each other. When pouring concrete, the stop bars 1 block the concrete. After the concrete is poured, the stop bars 1 are removed. Then, concrete of different grades is poured, and the fluidity of the concrete is used to fill the groove formed by the stop bars 1.

[0031] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
