Description

Technical Field

[0001] This utility model relates to the field of concrete construction technology, and in particular to a concrete pouring device for steel columns. Background Technology

[0002] During construction, a steel column concrete pouring device is needed to fill concrete inside the cylindrical column on the construction site.

[0003] A search revealed that patent document CN220058889U discloses a concrete pouring device for steel columns. One end is mounted on the steel column, and the other end is connected to a concrete pump pipe. The device comprises: a connecting pump pipe connected to the steel column; a connecting housing fixed to the end of the connecting pump pipe away from the steel column, the end of the connecting housing away from the connecting pump pipe communicating with the concrete pump pipe, and a flow channel within the connecting housing connecting the connecting pump pipe and the concrete pump pipe; a movable opening at the top of the connecting housing, the diameter of which is adapted to the diameter of the flow channel; and a movable interceptor plate installed at the movable opening and corresponding to the length of the movable opening, which blocks the flow channel by inserting the interceptor plate into the movable opening. This significantly saves time during construction, facilitating earlier completion of the project.

[0004] When using the above-mentioned patent, the dimensions of the connecting pump pipe and clamp are fixed, which is inconvenient to replace and cannot be adapted to steel columns of different sizes. Therefore, we propose a steel column internal concrete pouring construction device to solve the above problems. Utility Model Content

[0008] Connecting plate and clamp;

[0009] Mounting holes are provided on the connecting plate;

[0010] Threaded pipe connection, with threads installed in the mounting hole;

[0011] The delivery pipe is fixedly connected at one end to a threaded connecting pipe.

[0012] Two rectangular holes are provided on the connecting plate, and a rectangular block is slidably installed in each of the two rectangular holes;

[0013] Two connecting holes are provided on the two rectangular blocks respectively;

[0014] Two screws, one end of which is connected to the clamp, and the other end passes through the connecting hole;

[0015] Two nuts are threadedly connected to two screws, respectively.

[0016] Preferably, both ends of the clamp are provided with threaded grooves, and the two screws are threadedly connected to the two threaded grooves respectively.

[0017] Preferably, rectangular limiting grooves are provided on both the top inner wall and the bottom inner wall of the rectangular hole.

[0018] Preferably, rectangular limiting blocks are fixedly installed at both the top and bottom of the rectangular block, and the outer side of the rectangular limiting block is slidably connected to the inner wall of the rectangular limiting groove.

[0019] Preferably, a stop block is fixedly installed on the outer side of the conveying pipe, and multiple slots are provided on the outer side of the stop block.

[0020] Preferably, a connecting pipe is installed in the internal thread of the mounting hole.

[0021] Preferably, one end of the connecting pipe is fixedly connected to a connecting housing, and the connecting housing is connected to a concrete pump pipe.

[0022] Preferably, a rubber ring is fixedly installed on one side of the stop.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] This solution selects a delivery pipe suitable for the steel column injection port, connects the threaded connection pipe at one end of the delivery pipe to the installation hole, selects a clamp suitable for the steel column size, and then connects the two screws to the two threaded grooves on the clamp. If the steel column is large, the clamp size is large, and the distance between the two screws is large; if the steel column is small, the clamp size is small, and the distance between the two screws is small. Based on the distance between the two screws, push the two rectangular blocks to slide in the two rectangular holes. Then, insert one end of the delivery pipe into the steel column injection port, install the clamp on the steel column, pass the two screws through the two connection holes, and finally connect the two nuts to the two screws with threads.

[0025] This invention allows for the selection of appropriate clamps and conveying pipes based on the dimensions of the steel column, making it widely applicable. Attached Figure Description

[0045] In this embodiment, a connecting pipe 15 is installed in the internal thread of the mounting hole 10.

[0046] In this embodiment, one end of the connecting pipe 15 is fixedly connected to the connecting housing 16, and the connecting housing 16 is connected to the concrete pump pipe 17.

[0047] In this embodiment, a rubber ring is fixedly installed on one side of the stop 13.

[0048] In this embodiment, during use, a delivery pipe 12 suitable for the steel column injection port is selected, and the threaded connecting pipe 11 at one end of the delivery pipe 12 is threadedly connected and fixed to the mounting hole 10. A clamp 7 suitable for the steel column size is selected, and then the two screws 5 are threadedly connected and fixed to the two threaded grooves on the clamp 7. If the steel column is large, the clamp 7 is large, and the distance between the two screws 5 is large. If the steel column is small, the clamp 7 is small, and the distance between the two screws 5 is small. Based on the distance between the two screws 5, the two rectangular blocks 3 are pushed to slide in the two rectangular holes 2. Then, one end of the delivery pipe 12 is inserted into the steel column injection port, the clamp 7 is installed on the steel column, the two screws 5 are passed through the two connecting holes 4, and finally, the two nuts 6 are threadedly connected and fixed to the two screws 5.

A clamp 7 suitable for the size of the steel column is selected, and then the two screws 5 are threadedly connected and fixed to the two threaded grooves on the clamp 7. If the size of the steel column is large, the size of the clamp 7 is large, and the distance between the two screws 5 is large. If the size of the steel column is small, the size of the clamp 7 is small. The distance between the two screws 5 is small. By rotating the rotating block, the screw rod is driven to rotate, so that the rectangular limiting block 9 slides in the rectangular limiting groove 8. Then, the distance between the two rectangular blocks 3 is adjusted according to the distance between the two screws. Then, one end of the delivery pipe 12 is inserted into the steel column injection port, the clamp 7 is installed on the steel column, the two screws 5 are passed through the two connecting holes 4, and finally the two nuts 6 are threadedly connected and fixed to the two screws 5.
