Description

Technical Field

[0001] The invention relates to the technical field of chutes, and in particular to a chute device for sealing gaps in a roof flue. Background Art

[0002] At present, it is common to use chutes made of wood beams and templates as tools for sealing flue gaps. Wood beam templates are widely loved by workers due to their easy availability, simplicity and understanding. However, the wood beam templates are bulky, inconvenient to hold and operate, and flue walls of different heights need to be made multiple times. The construction technology is relatively backward, which can easily cause workers to slack off and quality risks. Against this background, the roof flue gap sealing chute device came into being, combining the chute body and the fixings into a whole, evolving from scattered operation and construction to combined integrated production, which can be used in rotation. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses a chute device for sealing the gap of a roof flue, comprising a lower chute body and an upper chute body, and the lower chute body is slidably matched inside the upper chute body. That is, the lower chute body and the upper chute body can be relatively telescopic, that is, the overall length can be adjusted.

[0004] The upper side wall of the upper chute body is penetrated with a lifting hole, so as to facilitate the lifting and lowering of the chute device into the flue.

[0005] The upper part of the upper chute body is fixedly connected with a fixed leg, the upper part of the upper chute body is fixedly connected with a fixing piece, both sides of the fixing piece are extended with side support rods, and the ends of the side support rods are fixedly connected with support plates. The fixed leg is used to be fixed on the upper end of the flue, while the support plate and the side support rod are against the inner wall of the flue.

[0006] Preferably, the inner wall of the upper chute body is provided with a groove, the side wall of the lower chute body is provided with a convex strip, and the convex strip is slidably fitted in the groove, so that the lower chute body and the upper chute body only slide in the length direction.

[0007] Preferably, the side wall of the lower chute body is provided with a plurality of first through holes, and the side wall of the upper chute body is provided with a plurality of second through holes, and first bolts are inserted through the first through holes and the second through holes to achieve the fixation of the lower chute body and the upper chute body. The first through holes and the second through holes are both provided at equal distances.

[0008] Preferably, a second bolt is provided at the end of the fixed leg, and the fixed leg is fixedly connected to the upper chute body by the second bolt. Similarly, the second bolt passes through the second through hole to fix the fixed leg.

[0009] Preferably, both sides of the fixing member are threadedly connected with third bolts, and the ends of the third bolts are against the side walls of the side support rods. The fixing member and the fixed legs are fixed in the upper chute in the same way. In addition, two side support rods are symmetrically arranged, and the two third bolts correspond to the two side support rods respectively. After the telescopic adjustment of the side support rods is completed, the third bolts are tightened to fix them.

[0010] Preferably, the lower chute body and the upper chute body are both injection molded, so that the chute device is lightweight.

[0011] The beneficial effects of the present invention are as follows:

[0012] 1. The customized method eliminates the need to use wooden boards on site, and can be adjusted according to the requirements of use. It can be reused, and avoids the problem of uncertain structural strength of chutes made of wooden boards.

[0013] 2. It is injection molded, light in weight and easy to lift. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0021] like Figure 1As shown, a chute device for sealing the gap of a roof flue comprises a lower chute body 1 and an upper chute body 3. The cross-sectional shapes of the lower chute body 1 and the upper chute body 3 are similar to the cross-sectional shapes of channel steels, and the lower chute body 1 is slidably fitted inside the upper chute body 3, that is, the lower chute body 1 extends out from the upper chute body 3.

[0022] A lifting hole 6 is provided through the upper side wall of the upper chute body 3 to facilitate the transportation and placement of the chute device.

[0023] like Figure 3 As shown, the upper part of the upper chute body 3 is fixedly connected with a fixed support leg 5 for fixing and supporting the chute device. The upper part of the upper chute body 3 is fixedly connected with a fixing piece 12. Side support rods 10 are extended on both sides of the fixing piece 12. The support rods 10 can be telescopically adjusted. The specific structure is that a through hole is provided on the fixing piece 12, and the support rods 10 are inserted in the through hole and adjusted according to the need of support. The end of the side support rod 10 is fixedly connected with a support plate 9, and the support plate 9 is used to resist the inner wall of the flue to prevent the chute device from shaking left and right.

[0024] The inner wall of the upper chute body 3 is provided with a groove, and the side wall of the lower chute body 1 is provided with a convex strip, and the convex strip is slidably fitted in the groove, so that the lower chute body 1 and the upper chute body 3 only slide in the length direction.

[0025] Combination Figure 1 and Figure 2 As shown, the side wall of the lower chute body 1 is provided with a plurality of first through holes 2, and the side wall of the upper chute body 3 is provided with a plurality of second through holes 4, and the first through holes 2 and the second through holes 4 are interspersed with first bolts 7 to fix the lower chute body 1 and the upper chute body 3, and the first through holes 2 and the second through holes 4 are arranged at equal distances. After the overall length adjustment of the lower chute body 1 and the upper chute body 3 is completed, and the first through holes 2 and the second through holes 4 coincide, the first bolts 7 can be passed through for fixing.

[0026] The end of the fixed leg 5 is provided with a second bolt 8, and the fixed leg 5 is fixedly connected to the upper chute body 3 by the second bolt 8. The second bolt 8 passes through the second through hole 4 to fix the fixed leg 5.

[0027] The third bolts 11 are threadedly connected to both sides of the fixing member 12, and the ends of the third bolts 11 abut against the side walls of the side support rods 10. The fixing method of the fixing member 12 is the same as the fixing method of the fixed leg 5.

[0028] like Figure 4As shown, when the chute device is in use, it needs to be adjusted according to the length of the flue, and then the chute device is lowered into the flue through the hanging hole 6, and the fixed support legs 5 are set at the upper end of the flue, while the side support rods 10 and the support plates 9 are against the inner wall of the flue to improve the stability of the chute device.
