DETAILED DESCRIPTION

[0016] The specific embodiment of the utility model is further explained below in combination with the drawings. It needs to be explained here that the explanation of these embodiments is used to help understanding the utility model, but does not constitute the limitation to the utility model. In addition, the technical features involved in each embodiment of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] As Figs. 1-2 Shown:

[0018] A kind of auxiliary tool of construction formwork dismantling, including several formwork support devices 2 and control rod 1, control rod 1 is provided with threaded section 11 at intervals, the formwork support device 2 is equipped at intervals on each threaded section 11;The formwork support device 2 is composed of support frame 21 and slide frame 22, slide frame 22 is located in support frame 21 and slides horizontally, the both sides of support frame 21 are symmetrically welded with bearing 211 (since bearing is mainly to bear horizontal force, so it is best to adopt thrust bearing), the both sides of slide frame 22 are penetrated and welded with bearing coaxial, and nut 221A matching with threaded section 11;The control screw passes through bearing 211 and nut 221A, and the both ends of threaded section 11 are interference fit with bearing 211;The top of support frame 21 one side is vertically installed with sleeve 23 that is communicated with the inside of support frame 21, the sleeve 23 is equipped with the ejector rod assembly 3 that can slide up and down.

[0019] The sliding frame 22 is mainly used to support the top rod assembly 3, but it needs to slide under the control of the control rod 1 during the formwork removal, so as to release the top rod assembly 3, so that the formwork loses support, in order to reduce the operation difficulty, the top end area of the sliding frame 22 is close to the bottom contour of the top rod assembly 3, at this time, the inside width of the supporting frame 21 is twice the outside width of the sliding frame 22, and the inside height is consistent with the outside height of the sliding frame 22, so that the up and down sides of the sliding frame 22 are limited to slide more stably (theoretically, limiting one side of the sliding frame 22 can prevent the sliding frame 22 from rotating with the control rod 1, and sliding along the threaded section 11).

[0020] The top rod assembly 3 is used to support the formwork, in order to adapt to the support of different heights within a certain range, the top rod assembly 3 comprises an inner threaded sleeve 31 and an outer threaded core rod 32, the inner threaded sleeve 31 is inserted into the sleeve 23, the outer threaded core rod 32 is screwed into the inner threaded sleeve 31, and the supporting plate 33 is fixed at the top end of the outer threaded core rod 32, the height can be adjusted by the depth of the outer threaded core rod 32 screwed into the inner threaded sleeve 31, and the supporting plate 33 is preferably rectangular, and a plurality of groups of nail holes 341 are arranged on the surface of the supporting plate 33, and iron nails or screws can be inserted into the nail holes 341 when the formwork is fixed.

[0021] In order to facilitate the twisting of the control rod 1, a hexagonal wrench head 12 is arranged at the end of the control rod 1 (it is not recommended to arrange a handle to avoid being touched by non-professionals).

[0022] When the formwork is installed, the height of the top rod assembly 3 is adjusted, the installation spacing on the control rod 1 is set (one or more threaded sections 11 can be arranged to install the formwork support device 2), then the formwork and the supporting plate 33 are fixed, when pouring is completed, the control rod 1 is twisted, the sliding frame 22 slides, the top rod assembly 3 loses support and slides down, so that the formwork loses support and is separated, and the formwork and the supporting plate 33 are still fixed together after the formwork loses support, but the height slides down, at this time, the formwork support device 2 is no longer subjected to vertical static pressure, so that the control rod 1 can be dragged to take out the entire formwork support device 2 and the formwork. It is very suitable for formwork removal in low and narrow areas, which is convenient for recycling and has high safety.

[0023] The embodiments of the utility model are described in detail in combination with the drawings, but the utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, replacements and modifications can be made to these embodiments without departing from the principles and spirits of the utility model, and still fall within the protection scope of the utility model.
