Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a convenient supporting device for fixing a flue at a hole opening. Background Art

[0002] Flue installation is the focus of building construction. Because of its large weight and the fact that it cannot serve as a load-bearing component of the upper flue, it is only a protective structure for the exhaust duct. Support measures must be installed at the reserved openings on each floor to ensure that it is installed firmly and vertically.

[0003] like Figure 1 As shown, the traditional flue installation requires two steel bars as supports placed horizontally on the reserved flue hole, and the flue is directly placed on the steel support. Wooden wedges are then placed in the reserved flue hole to tighten and position the flue. Finally, the reserved hole is filled and compacted with concrete. Before the concrete hardens, the wooden wedges need to be removed, which causes the previously adjusted flue to shift, making it impossible to ensure the verticality and installation position of the flue. Utility Model Content

[0004] Based on the above problems, the purpose of the utility model is to provide a convenient supporting device for fixing the flue at the hole, and the utility model adopts the following technical solutions:

[0005] The utility model provides a convenient supporting device for fixing a flue at an opening, comprising an inner plate, a cross-connecting plate extending outwardly from the middle of one side of the inner plate, an outer plate being arranged at an end of the cross-connecting plate away from the inner plate, a threaded sleeve being fixed on the outer plate, a screw rod being connected in the threaded sleeve, a pressure plate being arranged at an end of the screw rod close to the inner plate, the pressure plate being rotatably connected to the screw rod, a guide sliding hole being arranged on the cross-connecting plate for sliding cooperation with the pressure plate, the lower end of the pressure plate extending to the bottom of the cross-connecting plate after passing through the guide sliding hole, and the lower end of the pressure plate being inclined in a direction away from the inner plate; an axially adjustable limit piece is arranged on the screw rod at a side away from the inner plate, and the limit piece abuts against the floor plate.

[0006] Preferably, the limiting member includes a top plate and a nut, the top plate is sleeved on the screw rod, the nut is provided on a side of the top plate away from the floor plate, and the nut is threadedly connected to the screw rod.

[0007] Preferably, a polygonal column is provided in the middle area of ​​the screw rod.

[0008] Preferably, the pressing plate is T-shaped.

[0009] Compared with the prior art, the beneficial technical effects of the utility model are:

[0010] The utility model can support and fix the flue, and ensure the verticality of the installation of the upper and lower flues. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 2 As shown, in this embodiment, a convenient supporting device for fixing a flue at an opening is disclosed, comprising an inner plate 1, a cross-connecting plate 2 is provided extending outward from the middle of one side of the inner plate 1, an outer plate 3 is provided at the end of the cross-connecting plate 2 away from the inner plate 1, a threaded sleeve 4 is fixed on the outer plate 3, a screw 5 is connected in the threaded sleeve 4, a pressing plate 6 is provided at the end of the screw 5 close to the inner plate 1, the pressing plate 6 is rotatably connected to the screw 5, a guide slide hole 7 is provided on the cross-connecting plate 2 for sliding cooperation with the pressing plate 6, the lower end of the pressing plate 6 passes through the guide slide hole 7 and extends to the bottom of the cross-connecting plate 2, and the lower end of the pressing plate 6 is inclined in the direction away from the inner plate 1. An axially adjustable limiter 8 is provided on the screw 5 on the side away from the inner plate 1, and the limiter 8 is against the floor plate 9.

[0019] In this embodiment, the limiting member 8 includes a top plate 801 and a nut 802 . The top plate 801 is sleeved on the screw rod 5 . A nut 802 is provided on a side of the top plate 801 away from the floor plate 9 . The nut 802 is threadedly connected to the screw rod 5 .

[0020] In this embodiment, a polygonal column 501 is provided in the middle area of ​​the screw rod 5, so that it is convenient to rotate the screw rod 5 by a wrench.

[0021] In this embodiment, the pressing plate 6 is T-shaped.

[0022] like Figure 3 and 4 As shown, the use process of the utility model is as follows:

[0023] Generally, the flue 13 is located at the corner of the kitchen and bathroom, and its adjacent two sides are close to the wall 10. First, fix the device on the two sides of the flue 13 away from the wall 10. Specifically, the lower end of the upper flue is inserted between the inner plate 1 and the pressure plate 6, and the lower end of the upper flue is against the cross-connecting plate 2. Then tighten the screw rod 5 with a wrench so that the pressure plate 6 is tightly against the outer wall of the flue. Repeat the above steps to fix the other side of the lower end of the flue to the device. Then, the screw rod 5 of the device is placed on the floor plate 9 with a reserved hole. During this process, since the lower end of the pressure plate 6 is tilted away from the inner plate 1, the pressure plate 6 and the lower opening of the inner plate 1 form a bell mouth, which is just inserted into the upper end wall of the lower flue. Finally, rotate the limiter 8 to make it against the floor plate 9, thereby achieving the fixation of the upper and lower flues.

[0024] The embodiments described above are only descriptions of the preferred methods of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should fall within the protection scope determined by the claims of the present invention.
