Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to an air bag intercepting device for high and low grade concrete of beams and columns and a construction method thereof. Background Art

[0002] It is becoming more and more common to use high- and low-grade concrete for wall-column joints in high-rise buildings. The traditional interception method for high- and low-grade concrete at wall-column joints is welded wire mesh or airbag rods. Among them, airbag rods have a simple structure, low cost and wide application, but in actual application, the lower end of the airbag rod is easily fixed and "runs out of the mold". Similarly, the use of airbags is generally suitable for vertical interception, which is somewhat different from the oblique interception required by the design.

[0003] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0004] In order to overcome the defects of the prior art, an air bag interception device for high and low grade concrete in beams and columns and a construction method thereof are provided to solve the problems of easy mold slip at the bottom and unsuitability for oblique interception when using traditional air bag rods to intercept high and low grade concrete in wall-column nodes.

[0005] In order to achieve the above-mentioned purpose, an air bag interception device for high and low grade concrete of beams and columns is provided, comprising:

[0006] Two expansion air bags, the two expansion air bags are arranged opposite to each other;

[0007] A connecting tube, the two opposite sides of which are respectively connected to the two inflatable air bags;

[0008] The anchoring bone rod is detachably inserted into the connecting bag tube, and the lower end of the anchoring bone rod is anchored to the beam bottom template.

[0009] Furthermore, the expansion airbag and the connecting airbag tube are arranged in the same direction.

[0010] Furthermore, the connecting tube is a square tube.

[0011] Furthermore, the middle portion of the anchoring bone rod can be movably inserted into the square tube, and the upper end of the anchoring bone rod is connected to a handle, which is arranged on the outside of the square tube.

[0012] Furthermore, the handle is in a circular shape.

[0013] The present invention provides a construction method for a high-low grade concrete airbag interception device for beams and columns, which is characterized by comprising the following steps:

[0014] At the junction of high-grade concrete and low-grade concrete of beams and columns, a plurality of airbag interception devices for high-grade concrete and low-grade concrete of beams and columns are arranged in a row, so that the plurality of airbag interception devices for high-grade concrete and low-grade concrete of beams and columns are arranged along the length direction of the junction;

[0015] Pressing the anchoring bone rod downwards so that the lower end of the anchoring bone rod is anchored in the beam bottom template;

[0016] Inflate the expansion airbags of the plurality of airbag interception devices for beam-column high-low grade concrete so that the plurality of airbag interception devices for beam-column high-low grade concrete close the junction;

[0017] After the high and low grade concrete of the beam and column are solidified, the gas of the expansion airbag is exhausted, the anchoring bone rod is pulled out to take out the expansion airbag for turnover use.

[0018] The beneficial effect of the present invention is that the airbag interception device for beam and column high and low grade concrete of the present invention is used for intercepting high and low grade concrete at the node of wall and column at the construction site, and a connecting bag tube is arranged at the middle position of the two inflated airbags to lock the entire device on the beam bottom template in the form of an anchoring bone rod, thereby increasing the fixing firmness, avoiding the phenomenon of the lower mouth running out of the mold, and making the operation more convenient. In addition, when the airbag interception device for beam and column high and low grade concrete of the present invention is used for oblique interception, the junction of beam and column high and low grade concrete can also be well sealed.

It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] Reference Figures 1 to 7 As shown, the present invention provides an air bag interception device for high and low grade concrete of beams and columns, comprising: an expansion air bag 1, a connecting bag tube 2, and an anchoring bone rod 3.

[0030] Each of the airbag intercepting devices for beam-column high-grade and low-grade concrete of the present invention is equipped with at least two expansion airbags. Each expansion airbag is in the shape of a long strip. The length of the expansion airbag is greater than the thickness of the beam. When the expansion airbag is set at an angle, the length of the expansion airbag should be able to completely seal the junction of the beam-column high-grade and low-grade concrete.

[0031] Two expansion air bags 1 are arranged opposite to each other and are arranged along the length direction of the junction of the high and low grade concrete of the beam and column.

[0032] The opposite sides of the connecting tube 2 are connected to the two inflatable air bags 1 respectively.

[0033] As a preferred embodiment, the inflatable airbag 1 and the connecting airbag tube 2 are arranged in the same direction.

[0034] As a preferred embodiment, the connecting tube 2 is a square tube. In this embodiment, the connecting tube is a rectangular tube.

[0035] The long sides of the rectangular tube are connected to the inflatable airbag.

[0036] The anchoring bone rod 3 is detachably inserted into the connecting bag tube 2. The lower end of the anchoring bone rod 3 is anchored to the beam bottom template.

[0037] In this embodiment, the middle part of the anchoring bone rod 3 can be movably inserted into the square tube. The upper end of the anchoring bone rod 3 is connected with a handle 31. The handle 31 is arranged on the outside of the square tube.

[0038] As a preferred embodiment, the handle 31 is in a circular shape.

[0039] In this embodiment, the handle is pressed against the upper end of the connecting bag tube, so that the connecting bag tube is locked on the beam bottom template.

[0040] See also Figure 1 , Figure 6 and Figure 7 As shown, the present invention provides a construction method for a high-low grade concrete airbag interception device for beams and columns, comprising the following steps:

[0041] S1. At the junction of high-grade concrete and low-grade concrete of beams and columns, multiple airbag interception devices for high-grade concrete of beams and columns are arranged in a row, so that multiple airbag interception devices for high-grade concrete of beams and columns are arranged along the length direction of the junction.

[0042] S2. Press the anchoring bone rod 3 downward so that the lower end of the anchoring bone rod 3 is anchored in the beam bottom template 41.

[0043] S3, inflate the expansion airbags 1 of the multiple airbag interception devices for high and low grade concrete of beams and columns, so that the multiple airbag interception devices for high and low grade concrete of beams and columns close the junctions.

[0044] S4. After the high and low grade concrete 4 of the beam and column is solidified, the gas in the expansion bag 1 is discharged, and the anchoring bone rod 3 is pulled out to take out the expansion bag 1 for turnover use.

[0045] The air bag intercepting device for beam and column high and low grade concrete of the present invention is assembled in an uninflated state, and the anchoring bone rod is inserted into the connecting bag tube at the middle position of the two expansion air bags.

[0046] Based on the location of the junction of high-grade concrete and low-grade concrete of beams and columns, the airbag interception device for high-grade concrete and low-grade concrete of beams and columns of the present invention is inserted into the beam in rows along the length direction of the junction of high-grade concrete and low-grade concrete of beams and columns (the specific number depends on the width of the beam), and a little force is applied to drive the pin at the lower end of the anchoring bone rod into the bottom template of the beam. Then, the expansion airbags are inflated one by one to make the expansion airbags dense, so as to play a sealing role at the junction of high-grade concrete and low-grade concrete of beams and columns.

[0047] After the high and low grade concrete of the beams and columns are initially stabilized, the anchoring rods are pulled out, the air is deflated and the expansion airbags are pulled out for recycling.

[0048] The airbag interception device for beam and column high and low grade concrete of the present invention is used for intercepting high and low grade concrete at the joint of wall and column at the construction site. A connecting bag pipe is arranged at the middle position of two inflatable airbags to lock the whole device on the beam bottom template in the form of anchoring bone rods, thereby increasing the fixing firmness, avoiding the phenomenon of the lower mouth running out of the mold, and making the operation more convenient. In addition, when the airbag interception device for beam and column high and low grade concrete of the present invention is used for oblique interception, the junction of beam and column high and low grade concrete can also be well sealed.

[0049] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept. For example, the above features are replaced with (but not limited to) technical features with similar functions disclosed in the present application.
