Technical Field

[0001] The utility model belongs to the technical field of flue installation, and in particular relates to a flue installation auxiliary device for construction engineering. Background Art

[0002] Flue holes will be reserved during construction, and the staff will subsequently fill and install prefabricated flue panels in the reserved flue holes, and use concrete to fix the flue in the reserved position of the building. When the flue is installed, the staff below will lift the top of the flue to the corresponding position of the reserved hole, and the staff on the upper floor will hold the flue wall with their hands to align the side wall of the flue with the inner wall of the reserved hole. The flue will then be lifted by the lower staff and cooperate with the upper staff to pull the flue to install it in the predetermined position. During the installation process, there is only a gap of several centimeters between the outer periphery of the flue and the inner wall of the reserved hole of the flue. Due to the lifting and adjustment of the flue by the lower staff, the flue will be greatly displaced during the installation process, and some people's fingers may be squeezed and injured by the flue and the inner wall of the reserved hole of the building.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] Please refer to Figures 1 - 3 , the present utility model provides the following technical solutions: An auxiliary device for flue installation in construction engineering, including a supporting folding plate 1, a flue shielding piece 2 is fixedly connected to one side of the supporting folding plate 1, a lubricating gasket 21 is fixedly connected to the outer wall of the flue shielding piece 2, adjustable pressing plates 3 are provided on both inner walls of the supporting folding plate 1, an adjusting folding rod 31 is fixedly connected to one side of the adjustable pressing plate 3, a supporting rotating shaft seat 32 is rotatably connected to the outer wall of the adjusting folding rod 31, the supporting rotating shaft seat 32 is fixedly connected to the supporting folding plate 1, and a pressing friction pad 33 is fixedly connected to the inner wall of the adjustable pressing plate 3.

[0016] In this embodiment, the staff sets the support folding plate 1 and the support bottom frame 22 on the top of the flue, and then presses down the support folding plate 1 until the inner wall of the top of the support folding plate 1 contacts the top of the flue. The staff at the lower floor lifts and adjusts the flue as a whole, and places the top of the flue under the reserved hole of the building. The staff at the upper floor holds the adjustment folding rod 31 by hand to lift the adjustment folding rod 31. By lifting the two adjustment folding rods 31 at the same time, the adjustable extrusion plate 3 and the extrusion friction pad 33 can be quickly squeezed and fixed on the flue. When the tail of the adjusting folding rod 31 is lifted, the adjusting folding rod 31 flips and drives the adjustable squeezing plate 3 and the squeezing friction pad 33 to flip, so as to squeeze the squeezing friction pad 33 on the inner wall of the flue. Since the two squeezing friction pads 33 are vertically distributed, the friction forces between the two squeezing friction pads 33 and the two side walls of the flue are mutually restricted, and the supporting bottom frame 22 can restrict the flue. When the adjustable squeezing plate 3 and the squeezing friction pad 33 squeeze the flue, the adjustable squeezing plate 3 and the squeezing friction pad 33 will not be out of contact with the flue, and the squeezing friction pad 33 will be squeezed. The friction between the friction pad 33 and the flue fixes the device to the side wall of the flue. Then the staff adjusts the position of the top of the flue by pulling the folding rod 31 to align the edge of the flue plate with the inner wall of the reserved hole in the building, and lifts the flue to assist the staff below the floor to install the flue. During use, the staff's hands are located in the inner space of the flue. When the staff adjusts the position of the top of the flue, their hands will not be squeezed and injured by the flue and the inner wall of the reserved hole in the building. The device is more convenient to install and disassemble, and no bolts are required. The device is fixed to the side wall of the flue by installation and other means. When disassembling the device, the elastic traction handle 4 can be directly pulled upwards to remove the device from the flue, which is more convenient to use. With the help of the flue shielding sheet 2 and the lubricating gasket 21, the device is wrapped around the outer wall of the flue. The flue shielding sheet 2 and the lubricating gasket 21 replace the flue to contact the inner wall of the reserved hole in the building, which can reduce the friction force when the flue and the inner wall of the reserved hole in the building move relative to each other, and reduce the resistance encountered by the staff when adjusting the position of the flue through the device, so that the device can be more stably fixed to the side wall of the flue during use.

[0017] A clearance groove 11 is provided on the side wall of the support folding plate 1, and the adjusting folding rod 31 passes through the clearance groove 11. An inclined guide block 12 is fixedly connected to the inner wall of the support folding plate 1. By setting the clearance groove 11, the adjusting folding rod 31 can be given way, so that the adjusting folding rod 31 can be turned upside down for adjustment. By setting the inclined guide block 12, a guiding role can be played. When the support folding plate 1 is installed on the flue, the flue will not be blocked by the adjustable extrusion plate 3 and the extrusion friction pad 33.

[0018] The bottom end of the flue baffle 2 is fixedly connected to a support bottom frame 22, and the support bottom frame 22 is fixedly connected to the support folding plate 1; by setting the support bottom frame 22, the bottom opening of the lubricating gasket 21 can be supported, enabling the staff to more easily sleeved the support folding plate 1 and the lubricating gasket 21 on the flue side. At the same time, the support bottom frame 22 can limit the position of the flue.

[0019] The tails of the two adjusting folding rods 31 are close to each other, and the tails of the adjusting folding rods 31 are fixedly connected with tail protection soft balls 34; the tails of the two adjusting folding rods 31 are close to each other, enabling the staff to lift and flip the two adjusting folding rods 31 simultaneously with one hand, so as to free one hand for other operations. The staff can choose to lift with one hand or both hands according to actual needs. By setting the tail protection soft balls 34, a protective effect can be achieved, avoiding hand pain of the staff caused by the edge sharp corners of the adjusting folding rods 31.

[0020] The top end of the support folding plate 1 is fixedly connected with an elastic traction handle 4; by setting the elastic traction handle 4, it is convenient for the staff to lift the support folding plate 1, so that the staff can more easily remove the device from the flue.

[0021] The working principle and usage process of the present utility model: The staff sleeved the support folding plate 1 and the support bottom frame 22 on the top of the flue, and then pressed down the support folding plate 1 until the inner wall of the top end of the support folding plate 1 contacted the top end of the flue. The staff below the floor lifted and adjusted the whole flue, and placed the top end of the flue below the building reserved hole. The staff above the floor held the adjusting folding rod 31 with their hands to lift the adjusting folding rod 31. By simultaneously lifting the two adjusting folding rods 31, the adjustable pressing plate 3 and the pressing friction pad 33 can be quickly pressed and fixed on the inner wall of the flue. Then, the staff adjusted the position of the top end of the flue by pulling the adjusting folding rod 31, so that the edge of the flue plate was aligned with the inner wall of the building reserved hole, and lifted the flue to assist the staff below the floor in installing the flue. During the use process, the staff's hands were located in the inner space of the flue, and the hands would not be squeezed and injured by the inner walls of the flue and the building reserved hole when the staff adjusted the position of the top end of the flue. After the flue installation was completed, the elastic traction handle 4 was pulled upward to remove the device from the flue.
