Description

Technical Field

[0001] The utility model relates to floor construction, in particular to a floor pouring device which can be lifted along with the floor construction. Background Art

[0002] At present, the following three methods are generally used for floor pouring, but each has its own defects: 1) Ground pump combined with concrete placing boom for concrete pouring: The concrete placing boom matched with the ground pump has a small pouring radius and needs to be moved frequently. The time interval between moving the concrete placing boom to the next pouring area and starting to pour the area is too long, which is prone to quality defects such as exposed reinforcement and cold joints. In addition, the concrete placing boom will squeeze and deform the slab steel bars and formwork, and the weight will increase during pumping, which will damage the protective layer of the slab steel bars, resulting in poor concrete molding quality. In addition, the concrete placing boom needs to be manually pulled to turn; 2) Sky pump combined with concrete placing boom for concrete pouring: When the building reaches a certain height, the sky pump has a limited arm reach and cannot be used for high-rise construction; 3) Fixing the concrete placing boom at the elevator shaft or reserved opening for concrete pouring: Since the concrete placing boom is fixed, it cannot be used for high-rise construction.

[0020] The concrete placing machine includes a rotating platform 12 installed on the top of the top support section 6, a rotating drive mechanism 13 for driving the rotating platform 12 to rotate, a multi-section arm 14 installed on the rotating platform 12 and driven by a plurality of hydraulic cylinders 15, a hydraulic pump 16 for driving the hydraulic cylinders 15, and a pouring head 19 installed at the end of the multi-section arm 14. Figure 1 ;

[0021] The pump pipe includes a support section pump pipe 8 provided on each support section 6 and a multi-section arm pump pipe 9 provided along the concrete placing machine. The bottom support section pump pipe 8 is used for external ground pumping.

The outlet of the multi-section arm pump pipe 9 is connected to the pouring head 19. Figure 1 ;

[0022] In order to be able to carry out construction for various common floor heights, in this embodiment, the support section 6 has two types: standard sections and adjustable sections. The standard sections adopt the standard floor height, and the adjustable sections have optional heights of 1m, 1.5m, and 2m.

[0023] The steps of floor pouring construction in this embodiment are:

[0024] S1. Construction preparation: Determine the external connection position of the lowest support section pump pipe 8 according to the parking position of the pump truck, and determine the height of the standard section and the adjustment section according to the floor height.

[0025] S2. Pre-embedded during structural construction: When constructing the elevator shaft structure bottom plate 1, pre-embed the installation embedded parts 4 on it, and pre-embed the side support embedded parts 5 at the elevator shaft opening of the poured floor 2.

[0026] S3. Set up the support frame and install the support section pump pipe 8: After the strength of the elevator shaft structure base plate 1 meets the standard, first install the bottom support section 6 on the installation embedded parts 4, and then splice the support sections 6 upward in sequence until the support frame extends out of the floor 3 to be poured, and install the side support parts 7 on the side support embedded parts 5 so that the side support parts 7 limit the support frame along the line; at the same time, connect the support section pump pipes 8 of adjacent layers through the docking parts 10.

[0027] S4. Install the concrete placing machine and the multi-section arm pump pipe 9: hoist the turntable 12 and the rotary drive mechanism 13, the multi-section arm 14, the hydraulic pump 16, the pouring head 19 and the multi-section arm pump pipe 9 thereon, and install the turntable 12 on the top of the top support section 6, and then connect the top support section pump pipe 8 and the inlet of the multi-section arm pump pipe 9 through the docking piece 10.

[0028] S5. Preparation for pouring: After the pump truck is erected, the lowest support section pump pipe 8 is connected to the pump truck through the docking piece 10. The hydraulic pump 16 drives the hydraulic cylinder 15 to drive the multi-section arm 14 to move, and the rotary drive mechanism 13 drives the rotary table 12 to drive the multi-section arm 14 to rotate, so that the pouring head 19 is located at the initial position for pouring.

[0029] S6. Pouring: The pump truck pumps concrete, which is sprayed toward the current floor along the support section pump pipe 8, the multi-section arm pump pipe 9 and the pouring head 19. At the same time, the hydraulic pump 16 and the rotary drive mechanism 13 drive the multi-section arm 14 to move and rotate until the pouring of the current floor is completed.

[0030] S7. Add a layer of support section 6 and move the concrete placing machine up one layer: the hydraulic pump 16 and the rotary drive mechanism 13 drive the multi-section arm 14 to move and rotate to a stable position, remove the connection between the rotary table 12 and the top-level support section 6, remove the connection between the top-level support section pump pipe 8 and the inlet of the multi-section arm pump pipe 9, hoist the rotary table 12 and the rotary drive mechanism 13, multi-section arm 14, hydraulic pump 16, pouring head 19 and multi-section arm pump pipe 9 thereon to the poured floor, then hoist and splice a new layer of support section 6, connect the new support section pump pipe 8 to the support section pump pipe 8 of the next layer through the docking piece 10, then install the rotary table 12 on the top of the top-level support section 6, and then connect the new support section pump pipe 8 to the inlet of the multi-section arm pump pipe 9 through the docking piece 10.

[0031] S8, pour the next floor, and repeat S7 after pouring until all floors are poured.

[0032] In this embodiment, if Figure 1 As shown, the support section pump tube 8 is installed on the inner support member 11 inside the support section 6. The inner support member 11 can not only install the support section pump tube 8, but also improve the stability of the support section 6.

[0033] In this embodiment, if Figure 1 As shown, the hydraulic control cabinet 17 and the electrical control cabinet 18 of the material placing boom are both installed on the rotating platform 12.

[0034] In this embodiment, if Figure 1 As shown, the multi-section arm pump pipe 9 is arranged inside the concrete placing machine along the line, passing through each movable joint along the line, maintaining the continuity while not interfering with the movement of the movable joints. This solution is relatively common and belongs to the existing technology.

[0035] In this embodiment, the pouring head 19 adopts a hose, which can avoid damaging the floor and reduce the impact.

[0036] In this embodiment, the rotation drive mechanism 13 includes a hydraulic motor and a gear transmission assembly. The gear transmission assembly includes a driving gear and an outer ring gear that are meshed with each other. The driving gear is driven by the hydraulic motor, and the outer ring gear is provided on the movable part of the rotating table 12. This solution is relatively common and belongs to the existing technology.

[0037] In this embodiment, the docking member 10 is a ring hoop with a sealing function. This solution is relatively common and belongs to the prior art.

[0038] The support frame and pump pipe of the device adopt a spliced structure, which can be lifted upward as the floor is constructed. In addition, the installation of embedded parts 4, side support embedded parts 5, and side support parts 7 ensures the stability of the support frame, making it suitable for high-rise construction. In the device, the hydraulic pump 16 drives the hydraulic cylinder 15 to drive the multi-section arm 14 to move, and the rotary drive mechanism 13 drives the multi-section arm 14 to rotate by driving the rotary table 12. All areas within the operating radius of the multi-section arm 14 can be poured without manually pulling the concrete placing boom to turn. In the device, the concrete placing boom is supported on the support frame rather than the floor slab during pouring, which will not damage the quality of concrete molding.
