Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a pump pipe fixing device for passing through floors. Background Technology

[0002] Currently, during project construction, especially in high-rise and super high-rise building construction, pump pipes need to pass through floors to pump concrete. Construction holes are pre-drilled at corresponding locations on each floor to allow the pump pipes to pass through. During concrete pumping, the pump pipes need to be secured to prevent vertical and lateral movement. The current securing method mainly uses ring fasteners to clamp the pump pipes, and then supports connected to the ring fasteners within the opening to limit the pump pipe's displacement. However, this securing method has a problem: the supports within the opening are at risk of detachment, causing them to fall and posing a safety hazard. For example, in patent publication CN214008320U, the securing device is entirely located within the opening; if the structure connecting it to the inner wall of the opening detaches, the entire securing device will fall. Utility Model Content

[0003] To address the problems in the prior art, this application proposes a pump pipe through-floor fixing device, which is installed on the upper floor of the floor slab. The device eliminates the risk of falling from the floor opening and is highly safe.

[0004] This utility model proposes a pump pipe passing through a floor fixing device, comprising: an upper support steel beam, a lower support steel beam, and telescopic clamping components; there are two lower support steel beams, each anchored to the upper end of the floor slab and distributed opposite to each other on both sides of the opening in the floor slab for the pump pipe to pass through; there are two upper support steel beams, each fixed to the upper end of the lower support steel beam and distributed opposite to each other on the other two sides of the opening, with each end of the upper support steel beam connected to the two lower support steel beams respectively; there are four telescopic clamping components, one of which is provided on the opposite inner side of each of the two lower support steel beams and one on the opposite inner side of each of the two upper support steel beams; the telescopic clamping component includes a clamping plate and a telescopic component, the back of the clamping plate is connected to the telescopic component, and the telescopic component is connected to the upper support steel beam or the lower support steel beam.

[0005] Furthermore, the telescopic clamp also includes a strain monitoring device; the strain monitoring device is connected to the clamping plate and is used to monitor the strain of the pump pipe pressed against by the clamping plate.

[0006] Furthermore, the telescopic component includes a fixed threaded sleeve, a screw, and a locking nut; one end of the fixed threaded sleeve is fixedly connected to the back of the clamping plate, and the other end is threadedly engaged with the screw; the screw is threadedly connected to the upper support steel beam or the lower support steel beam; the locking nut engages with the screw and is located between the fixed threaded sleeve and the upper support steel beam or the lower support steel beam.

[0007] Furthermore, the fixing device also includes connecting bolts; the upper support steel beam and the lower support steel beam are connected by the connecting bolts.

[0008] Furthermore, the fixing device also includes a lower support fixing bolt, through which the lower support steel beam is connected to the floor slab.

[0009] Furthermore, the clamping plate is an arc-shaped plate.

[0010] The beneficial effects of this utility model include: by fixing two lower support steel beams on the floor slab and on both sides of the opening, and then fixing two upper support steel beams on top of the lower support steel beams, and by setting a telescopic clamp on the inner side of each of the two upper and two lower support steel beams respectively, the pump pipe passing through the opening is clamped and fixed using the telescopic clamps. This not only avoids the risk of the fixing device falling out of the opening and ensures construction safety, but also allows the telescopic clamps to be used for pump pipes of different sizes and models, resulting in better pump pipe fixing. By monitoring the strain of the pump pipe through a strain monitoring device installed on the clamp, the blockage location of the pump pipe can be quickly located, greatly reducing the time for locating the blockage, reducing losses, and avoiding quality risks.
