Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to an auxiliary device for casting concrete in a steel pipe bundle. Background Art

[0002] With the development of prefabricated buildings, the steel pipe concrete bundle shear wall structure is gradually replacing the traditional concrete shear wall structure. The steel pipe concrete bundle shear wall structure is composed of U-shaped steels arranged in groups and welded into a steel pipe bundle. After welding, concrete is poured inside for reinforcement. When pouring the internal concrete of this new type of shear wall structure, since there are many and narrow pouring ports in the steel pipe bundle, pouring one by one is rather cumbersome, which affects the construction efficiency. Therefore, it is necessary to design an auxiliary device for casting concrete in a steel pipe bundle. Summary of the Invention

[0003] An auxiliary device for casting concrete in a steel pipe bundle is provided for the deficiencies in the prior art.

[0004] The technical solution of the utility model to solve the above problems is as follows:

[0005] An auxiliary device for casting concrete in a steel pipe bundle includes a hopper. The hopper includes an upper part and a lower part. The upper part has a quadrangular pyramid structure with a larger top and a smaller bottom, and the lower part has a rectangular structure. Lifting handles are respectively arranged on the outer sides of the upper part; the interior of the lower part is separated into several chambers corresponding to one steel pipe bundle pouring port by a partition board. A wedge-shaped flow guide plate is arranged on the upper part of the partition board, and a plurality of support legs are symmetrically welded on both sides of the lower part of the hopper.

[0006] Further, two circles of reinforcing ribs are arranged around the exterior of the lower part, one circle is arranged on the upper part of the lower part, and the other circle is arranged on the lower part of the lower part.

[0007] Further, the reinforcing ribs are connected to the lower part by rivets.

[0008] Further, the support legs are welded to the reinforcing ribs.

[0009] By arranging lifting handles on the upper part of the hopper, the utility model can facilitate the transfer during construction; by arranging a partition board in the lower part of the hopper to separate multiple chambers, the pouring of multiple steel pipe bundle pouring ports can be carried out simultaneously. By symmetrically welding a plurality of support legs on both sides of the lower part of the hopper, the functions of support and positioning can be achieved. The utility model has a simple structure, convenient positioning, can be reused, improves the pouring rate, reduces the waste during concrete pouring, improves the construction efficiency, and saves the construction cost.

Specific implementation mode

[0015] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below with reference to specific drawings.

[0016] Embodiment, please refer to Figure 1 — Figure 4 A steel pipe bundle concrete pouring auxiliary device as shown. The device is made of steel as a whole and includes a hopper. The hopper includes an upper part 1 and a lower part 3. The upper part 1 has a quadrangular pyramid structure with a large top and a small bottom, and the lower part 3 has a rectangular structure. Lifting handles 2 are respectively arranged on the outer sides of the upper part 1. The lifting handles 2 are used for lifting and hoisting to facilitate transfer during construction. The inside of the lower part 3 is divided into three chambers respectively corresponding to a steel pipe bundle pouring port 11 by a partition plate 8, that is, each chamber corresponds to a steel pipe bundle pouring port 11. A wedge-shaped deflector 7 is arranged on the upper part of the partition plate 8. The wedge-shaped deflector 7 can play a role in diverting and preventing accumulation. Specifically, on the one hand, the wedge-shaped deflector 7 can guide the concrete into the corresponding chamber, and on the other hand, it can prevent the concrete from falling on the connecting part 10 of the steel pipe bundle. Preferably, the top of the wedge-shaped deflector 7 is rounded. The partition plate 8 can also prevent the lower part 3 from deforming during pouring. Four support legs 5 are symmetrically welded on both sides of the lower part of the hopper. The support legs 5 can play a role in support and positioning.

[0017] In this embodiment: two circles of reinforcing ribs 4 are arranged around the outside of the lower part 3. One circle is arranged on the upper part of the lower part 3, and the other circle is arranged on the lower part of the lower part 3. Preferably, the reinforcing rib 4 is a steel strip. Further, the reinforcing rib 4 is connected to the lower part 3 by rivets 6. Further, the support leg 5 is welded to the reinforcing rib 4.

[0018] During the construction of the present utility model, the present utility model is hoisted above the steel pipe bundle so that the support legs 5 are positioned around the U-shaped steel 9 (as Figure 4As shown in the figure, concrete is poured. The concrete passes along the upper part 1 through the wedge-shaped flow guide plate 7 and enters the three chambers under the action of the partition plate 8, flowing into the three steel pipe bundle pouring ports 11. During pouring, the four middle support legs 5 are at the joints around the middle U-shaped steel 9, which can prevent the concrete from overturning due to too large impact force during pouring.
