Description

Technical Field

[0001] The utility model relates to a concrete intercepting device with different strengths. Background Art

[0002] When the same beam needs to be poured with concrete of different strengths and grades in sections, it is necessary to set an interception device at the section position of the beam to intercept the poured concrete of different strengths. Especially at the beam-column joint, concrete of different strengths and grades is often used for pouring.

[0003] Chinese utility model patent specification CN 219451529 U discloses a binding type high and low grade concrete interception device, which discloses the use of air bags as interception devices. After the steel cage of the beam is tied, a plurality of uninflated air bags are inserted between the transverse steel bars, and the air bags are inflated with an air pump. After the air bags are inflated, the gaps between the transverse steel bars can be filled, and then concrete can be poured.

[0004] However, the airbag itself is relatively weak and can be easily deformed or displaced by the impact of concrete when pouring concrete, resulting in poor interception effect. Summary of the invention

[0005] The utility model aims to provide a concrete interception device with different strengths, which is used for being placed in a steel cage of a beam to intercept poured concrete, and comprises an inflatable and deflable air bag and a retaining frame; the retaining frame is in the shape of a comb, comprising a main frame and a plurality of comb teeth arranged in parallel and at intervals for inserting into the steel cage of the beam, the upper end of each comb tooth is connected to the main frame, and the lower end of each comb tooth is a free end; each comb tooth is respectively equipped with an air bag, and the back of each air bag is provided with an outer ring sleeve for the comb teeth to be inserted.

[0006] The utility model can install and limit the airbag on the comb teeth by using the outer ring sleeve, and can support the airbag by using the comb teeth to avoid deformation or displacement of the airbag, so as to ensure the effect of intercepting concrete. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The present application scheme is further described below in conjunction with the accompanying drawings.

[0017] like Figures 1 to 7 A concrete interception device 400 of different strengths is shown, which is used to be placed in a steel cage 100 of a beam to intercept poured concrete, and includes an inflatable and deflable air bag 10 and a retainer 20;

[0018] The retainer 20 is in the shape of a comb, including a main frame 201 and a plurality of comb teeth 202 arranged in parallel and at intervals to be inserted into the steel cage 100 of the beam, the upper end of each comb tooth 202 is connected to the main frame 201, and the lower end 203 of each comb tooth is a free end;

[0019] Each comb tooth 202 is equipped with an air bag 10, and the back side 101 of each air bag is provided with an outer ring 102 for the comb teeth 202 to be inserted. The technical solution uses the outer ring to install and limit the air bag on the comb teeth, and the comb teeth can support the air bag to prevent the air bag from deformation or displacement, so as to ensure the effect of intercepting concrete. In addition, each air bag can be detached from the retaining frame for easy cleaning and storage.

[0020] Each airbag 10 has multiple outer rings 102, and these outer rings 102 are arranged at intervals along the length direction of the airbag 10. This technical solution can enable the airbag to be stably and reliably installed on the comb teeth, improve the ability of the comb teeth to support the airbag, and reduce the risk of the airbag shifting during concrete pouring. In this embodiment, Figure 7 Two outer collars 102 are shown for each airbag 10 .

[0021] The main frame 201 of the retainer is provided with a handle 204 to facilitate insertion or removal of the reinforcement cage of the beam.

[0022] The specific operation process of this utility model is as follows:

[0023] like Figures 1 to 3 As shown;

[0024] To complete the steel cage binding of the beam 100 and the column 200 and the construction of the concrete pouring formwork 300, a concrete interception device 400 needs to be placed in the steel cage of each beam;

[0025] In each concrete intercepting device 400, firstly, an uninflated airbag 10 is installed on each comb tooth 202 of the retaining frame 20, and then the retaining frame 20 and all the airbags 10 thereon are inserted into the steel cage 100 of the beam, and the retaining frame 20 and the steel cage 100 of the beam can be bound with the help of steel wires (not shown in the figure), and then each airbag 10 is inflated with an air cylinder (not shown in the figure), and after the airbags 10 are inflated, the gaps between the steel bars can be filled.

[0026] Finish pouring concrete;

[0027] After the concrete pouring is completed, each airbag 10 is deflated and shrunk and separated from the concrete, the retaining frame 20 and all the airbags 10 thereon are pulled out together, and each airbag 10 is pulled away from the comb teeth 202 and simply cleaned for easy storage and reuse.
