Description

Technical Field

[0001] This utility model relates to the technical field of concrete pouring auxiliary devices, specifically a portable auxiliary device for pouring concrete for bridge piers. Background Technology

[0002] Cast-in-place concrete piers are widely used in highway and municipal engineering construction. During the concrete pouring of bridge piers, pumped concrete combined with a tremie pipe is often used. During pouring, the tremie pipe needs to be removed from the pier to facilitate the work of the vibration personnel. However, rigid tremie pipes have the following drawbacks: 1. Inconvenient to carry and transport; 2. Inconvenient to retrieve, affecting work efficiency; 3. It is inconvenient to maintain after damage occurs.

[0003] To address this issue, the inventors designed a portable auxiliary device for concrete pouring of bridge piers to replace the tremie pipe. Summary of the Invention

[0004] To address the technical problems existing in the background art, this utility model provides a portable auxiliary device for concrete pouring of bridge piers.

[0005] The technical solution of this utility model is as follows: A portable auxiliary device for concrete pouring of bridge piers includes: The first connector is a ring structure with an L-shaped cross-section. The horizontal part extends outward, and the end is provided with an upward-extending hook. The upper part of the first connector fixes the lower end of the conveyor cloth. The second connector is a ring structure with an inverted L-shaped cross-section. The horizontal part extends outward, and the lower part of the second connector is fixed to the upper end of the conveyor cloth. The ring clamp includes a left clamp and a right clamp that are hinged together. The cross-section is C-shaped, with a downward-extending hook at the upper end and a horizontal lower part. The internal space of the ring hoop can simultaneously accommodate the first connector and the second connector, and the lower hook of the ring hoop can be hooked on the inner side of the upper hook of the first connector.

[0006] This invention replaces the string tube with a conveyor cloth, which greatly improves portability. Moreover, the flexibility of the conveyor cloth makes it easier for vibrators to work without having to remove the auxiliary device, thus improving efficiency.

[0007] In addition, the first and second connectors are connected by a ring hoop, which makes the auxiliary device very long, which can be determined according to the height of the pier column, and extends to the bottom of the pier column. Compared with the traditional shorter tremie pipe, this avoids the free fall of concrete, reduces the occurrence of concrete segregation, and ensures the construction quality of the pier column. On the other hand, it can be disassembled and reassembled through ring clamps, making it easy to replace damaged parts. It can also change the height and diameter of piers according to different pier sizes, saving construction costs and having good economic benefits.

[0008] Furthermore, the first connector, the second connector, and the intermediate connecting conveyor cloth constitute an integral structure, facilitating carrying and installation.

[0009] As a preferred embodiment, the inner diameters of the first connector and the second connector are the same.

[0010] In one embodiment, the upper outer wall of the first connector has several through holes along the circumference, and the top has a circular slot with a diameter greater than the inner diameter. The depth of the circular slot is lower than that of the through holes. A fixing member is inserted into the through holes to fix the conveying cloth to the first connector.

[0011] Similarly, the lower outer wall of the second connector has several through holes along the circumference, and the bottom has a circular slot with a diameter greater than the inner diameter. The depth of the circular slot is lower than the through holes. A fixing member is inserted into the through holes to fix the conveying cloth to the first connector.

[0012] The fastener can be a connecting pipe that passes through the conveyor cloth under the action of hot melting. After being squeezed and deformed at both ends, it is attached to the inner and outer walls of the first or second connecting member.

[0013] As an improvement, the upper and lower hooks are at the same height, allowing the ring to be in close contact with the first connecting piece.

[0014] After both the first and second connectors are engaged with the ring clamp, the minimum gap between their adjacent surfaces should be greater than the height of the upper hook to facilitate the removal of the ring clamp. Of course, this gap should not be too large, ideally between 0-5mm.

[0015] As one implementation method, the conveyor cloth can be made of nylon fiber cloth, and the effect is even better after PTFE treatment.

[0016] Through the above design, this utility model provides a portable auxiliary device for concrete pouring of bridge piers. By replacing the tremie pipe with a conveyor cloth, the portability is greatly improved. Moreover, the flexibility of the conveyor cloth makes it easy for the vibrator operator to work without having to take the auxiliary device out, thus improving efficiency.

[0017] In addition, the first and second connectors are connected by a ring hoop, which makes the auxiliary device very long, which can be determined according to the height of the pier column, and extends to the bottom of the pier column. Compared with the traditional shorter tremie pipe, this avoids the free fall of concrete, reduces the occurrence of concrete segregation, and ensures the construction quality of the pier column. On the other hand, it can be disassembled and reassembled through ring clamps, making it easy to replace damaged parts. It can also change the height and diameter of piers according to different pier sizes, saving construction costs and having good economic benefits. Attached Figure Description

[0019] See Figures 1-3 This embodiment provides a portable auxiliary device for concrete pouring of bridge piers, including: The first connector 1 is a ring structure with an L-shaped cross section. The horizontal part extends outward and the end is provided with an upward-extending hook 11. The lower end of the conveyor cloth 4 is fixed at the upper part of the first connector 1. The second connector 2 is a ring structure with an inverted L-shaped cross section. The horizontal part extends outward, and the lower part of the second connector 2 fixes the upper end of the conveyor cloth 4. The ring clamp 3 includes a left clamp and a right clamp that are hinged together. The cross-section is C-shaped, with a downward-extending hook at the upper end and a horizontal lower part. The C-shaped cavity inside the ring hoop 3 can simultaneously accommodate the first connector 1 and the second connector 2, and the lower hook of the ring hoop 3 can be hooked inside the upper hook 11 of the first connector 1.

[0020] The first connecting piece 1, the second connecting piece 2, and the intermediate connecting conveyor cloth 4 constitute a basic overall structure, which is convenient for carrying and installation. Depending on the size of the pier column, multiple pieces can be connected by ring hoops to replace the tremie cylinder.

[0021] As a preferred option, the first connector 1 and the second connector 2 have the same inner diameter, which allows the concrete to flow smoothly from top to bottom.

[0022] The first connector 1 and the second connector 2 have the same outer diameter, which makes it easy for the ring clamp 3 to simultaneously engage the first connector 1 and the second connector 2.

[0023] Both the first connector 1 and the second connector 2 can be made of high-strength aluminum alloy.

[0024] The external shape and usage of the ring 3 in this embodiment are the same as in the prior art. See [link / reference]. Figure 2 As shown, this application will not repeat the details. The main improvement of this application is to the internal structure, enabling it to be used in conjunction with the first connector 1 and the second connector 2.

[0025] In this embodiment, the upper hook 11 and the lower hook are at the same height, so that the ring hoop 3 is in close contact with the first connecting member 1.

[0026] After the first connector 1 and the second connector 2 are both engaged with the ring clamp 3, the minimum gap between their adjacent surfaces should be greater than the height of the upper hook 11 to facilitate the removal of the ring clamp 3. Of course, this gap should not be too large, and should be between 0-5mm.

[0027] Before using the clamp 3, align the lower end faces of the second connector 2 of the next integrated auxiliary device with the lower end face of the first connector 1 of the previous integrated auxiliary device. Then, put the clamp 3 onto the first connector 1 and the second connector 2, so that the second connector 2 is flush with the lower inner end face of the clamp 3. After the clamp 3 is tightened, release your hand so that the lower hook 31 of the clamp 3 is closely fitted with the upper hook 11 of the first connector 1. The whole process can be completed by one person or two people working together.

[0028] See Figure 3 In one embodiment, the upper outer wall of the first connector 1 has several through holes circumferentially formed, and a circular slot with a diameter larger than the inner diameter of the first connector 1 is formed at the top. The width of the circular slot matches the thickness of the conveying cloth 4, and its depth is lower than the through holes. The entire slot is located at the middle of the top of the first connector 1. After the conveying cloth 4 is inserted into the slot, a fixing member is inserted into the through holes to fix the conveying cloth 4 to the first connector 1. This step is completed in advance.

[0029] Similarly, the lower outer wall of the second connector 2 has several through holes along the circumference, and the bottom has a circular slot with a diameter greater than the inner diameter of the second connector 2. The depth of the circular slot is lower than the through holes. A fixing member is inserted into the through holes to fix the conveying cloth 4 onto the first connector 1.

[0030] See Figure 4 In this embodiment, the fastener is a connecting tube 5, which is made of a relatively soft metal, such as aluminum. Under the action of hot melting, it can burn through the conveyor cloth 4 and be inserted into the through hole. Then, the two ends of the connecting tube 5 are squeezed and deformed by a tool so that they are attached to the inner and outer walls of the first connecting member 1 or the second connecting member 2, thus fixing the conveyor cloth.

[0031] This invention replaces the string tube with a conveyor cloth 4, which greatly improves portability. Moreover, the flexibility of the conveyor cloth 4 makes it easier for vibrators to work without having to remove the auxiliary devices, thus improving efficiency.

[0032] As one implementation method, the conveyor cloth 4 can be made of nylon fiber cloth, which is even better after being treated with PTFE, which can greatly improve the wear resistance of nylon fiber and ensure construction economy.

[0033] In addition, the connection between the first connector 1 and the second connector 2 via the ring clamp 3 allows the auxiliary device to be quite long, depending on the height of the pier column, extending to the bottom of the pier column steel formwork 6. (See [reference]). Figure 5 As shown. Compared to traditional shorter tremie pipes, this design avoids the free fall of concrete, reduces the incidence of concrete segregation, and ensures the construction quality of the pier columns; On the other hand, the ring 3 can be disassembled and reassembled, making it easy to replace damaged parts. It can also be used to change the height and diameter of the pier according to the different pier dimensions, saving construction costs and achieving good economic benefits.
