DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] As Figures 1-4 shown, the present utility model provides a formwork turnover structure for a super-high chimney, including an adjustment assembly 100, a template 200, and a support steel frame 300. The adjustment assembly 100 includes an adjustment plate 101, a protruding plate 102, a strengthening column 103, a pull rod 104, and an installation steel plate 109. The ends of the protruding plate 102 are fixed to the outside of the adjustment plate 101. The strengthening column 103 is arranged inside the adjustment plate 101. The pull rod 104 penetrates through the strengthening column 103. A connection hole 105 is opened at the upper end of the strengthening column 103. A connection column 106 is fixed to the lower end of the strengthening column 103. The installation steel plate 109 is arranged outside the adjustment plate 101;

[0025] The template 200 is arranged inside the adjustment component 100. The template 200 includes a connection end 201 and a movable end 202. The connection end 201 is a protruding design. The connection end 201 is slidably connected to the inner wall of the adjustment component 100, and the movable end 202 is movably connected to the connection end 201.

[0026] Further, in this embodiment, the adjustment plate 101 is of a C-shaped design. The protruding plates 102 are located on both sides of the opening of the adjustment plate 101. The protruding plates 102 are of a V-shaped design. The strengthening columns 103 are welded inside the protruding plates 102. The opening design of the adjustment plate 101 provides a certain contraction space. The design of the protruding plates 102 facilitates the installation of the strengthening columns 103 inside the protruding plates 102 and strengthens the gaps of the protruding plates 102 to prevent the protruding plates 102 from deforming.

[0027] In this embodiment, the pull rod 104 passes through the two strengthening columns 103 and is in threaded cooperation with the two strengthening columns 103. The connection hole 105 is adapted to the connection column 106. Through holes 107 are opened on the outer sides of the strengthening columns 103, the connection column 106, and the protruding plates 102. Threaded rods 108 are in threaded cooperation inside the through holes 107. The two strengthening columns 103 are connected by the pull rod 104, and the threads on the surface of the pull rod 104 are of a double-thread design, so as to realize the rotation of the pull rod 104 to control the inward or outward movement of the two strengthening columns 103 on its surface. The connection between the connection column 106 and the strengthening column 103 is strengthened by the threaded rod 108.

[0028] In this embodiment, two symmetrical mounting steel plates 109 are arranged on the outer side of the adjustment plate 101. The mounting steel plates 109 are respectively screwed to the adjustment plate 101 and the support steel frame 300. Connection blocks 1010 are vertically arranged at the outer ends of the mounting steel plates 109. The adjustment plate 101 is mounted on the support steel frame 300 through the mounting steel plates 109, and steel bars are mounted through the connection blocks 1010 for reinforcement to stabilize the installation work of the adjustment plate 101 and realize the installation work of the adjustment component 100.

[0029] In this embodiment, both the adjustment plate 101 and the protruding plates 102 are made of one of carbon structural steel plates or low alloy structural steel plates. The strengthening columns 103 are seamless steel pipe columns. The materials of the adjustment plate 101 and the protruding plates 102 enable them to be bent under the condition of ensuring strength, which is convenient for the adjustment work of the adjustment plate 101.

[0030] In this embodiment, an activity groove 204 adapted to the movable end 202 is opened inside the connection end 201. A guide plate 203 is fixed on one side of the movable end 202. A guide groove 205 adapted to the guide plate 203 is opened on the outer surface of the template 200. The movable end 202 can enter the connection end 201 through the activity groove 204 for tightening work.

[0031] In this embodiment, the guide plate 203 is slidably connected to the guide groove 205. A groove for the movement of the guide plate 203 is formed on the inner wall of the adjustment plate 101. The shape of the adjustment plate 101 is adapted to the shape of the template 200. The movement of the template 200 is stabilized by the cooperation of the guide groove 205 and the guide plate 203, and the protruding part of the guide plate 203 is facilitated to move within the adjustment plate 101 through the groove.

[0032] Specifically, when constructing a super-high chimney, a support steel frame 300 is preset according to the designed chimney size. First, a template 200 and an adjustment assembly 100 are arranged at the bottom layer. Another template 200 and an adjustment assembly 100 are installed on the bottom-layer template 200. Between adjacent adjustment assemblies 100, the upper connecting column 106 is inserted into the lower connecting hole 105 and fixed tightly by a threaded rod 108 to assemble the templates 200. Then, concrete 400 is poured according to the templates 200. After the concrete 400 is formed, the threaded rod 108 is removed, the bottom-layer template 200 is removed, and the bottom-layer template 200 is moved above the adjacent template 200. This operation is repeated for form turnover until the chimney pouring is completed.

[0033] Considering that the size of the chimney needs to be adjusted during actual pouring, for this reason, an adjustment assembly 100 is arranged on the outer side of the template 200 for adjustment. Specifically, when the template 200 needs to be adjusted, the pull rod 104 is rotated, and two reinforcing columns 103 are controlled to move inwards or outwards on its surface based on the threads on the surface of the pull rod 104. When the reinforcing columns 103 move inwards, the adjustment plate 101 is driven to contract inwards. At the same time, the movable end 202 of the template 200 moves towards the movable groove 204 of the fixed end, and the guide block moves synchronously within the guide groove 205 to achieve synchronous tightening of the template 200. Similarly, when the reinforcing columns 103 move outwards, the adjustment plate 101 expands and the template 200 expands. However, considering the expansion limit of the template 200, when the template 200 expands to an open shape, a template 200 of a larger size needs to be replaced so as not to affect the construction of the chimney.

[0034] When performing form turnover, considering that the bottom-layer template 200 needs a certain space to separate it from the upper connecting column 106, therefore, a sealing rubber ring is arranged at the bottom of the bottom-layer template 200 to lift the bottom-layer template 200 by a part. After the bottom layer is formed, the sealing rubber ring is removed first, and there is a space between the bottom-layer template 200 and the ground for separation between the upper and lower layers. The specific space distance is adjusted and set according to the actual construction.

[0035] In addition, the guiding groove 205 on the template 200 does not penetrate through the template 200. The guiding block only moves on the outer surface of the template 200. Both the upper and lower ends of the adjusting plate 101 are provided with bending parts, which are located at the upper and lower ends of the template 200. The thickness of the bending parts is the same as that of the template 200, and the inner side surfaces of the bending parts are closely attached to the end surfaces of the template 200, blocking the end parts of the movable groove 204. Through reasonable design, it is avoided that the concrete 400 enters the movable groove 204 during pouring, which affects the construction of the chimney.

[0036] The components such as the adjusting plate 101, the protruding plate 102, the reinforcing column 103, the tension rod 104, the connecting hole 105, the connecting column 106, the through hole 107, the threaded rod 108, the mounting steel plate 109, the connecting block 1010, the template 200, the guiding plate 203, the support steel frame 300, and the concrete 400 of the present utility model are all common standard parts or parts known to those skilled in the art. Their structures and principles can all be known by those skilled in the art through technical manuals or obtained through conventional experimental methods.
