Description

Length-adjustable construction formwork is to drawing device
Technical field
The utility model relates to a kind of formwork opposite-pulling device, in particular, relates to a kind of length-adjustable construction formwork to drawing device.
Background technology
In current building construction process, for ensureing Construction Quality, construction wall adopts the frame construction of steel concrete mostly, and frame construction needs to use construction formwork, construction formwork is fixed with split bolt usually, but due to the width of body of wall different, the length of the split bolt of use is different, therefore causes building operations cost to increase.
Utility model content
The utility model for the deficiency of existing product, and provides simple, practical, the length-adjustable construction formwork of a kind of structure to drawing device.
Length-adjustable construction formwork of the present utility model is to drawing device, described device comprises construction formwork, to pull bar, sleeve pipe, clamp nut, described sleeve pipe is placed in the middle of two construction formworks, described pull bar to be fixedly connected with sleeve pipe through construction formwork, the described end to pull bar is provided with clamp nut, described clamp nut and be provided with joint ring between pull bar.The centre of described sleeve pipe is fixedly connected with sealing piece.Described sleeve pipe and pull bar is threaded connection.Described clamp nut is buttferfly-type nut.Described sleeve pipe quantity is 3.
The beneficial effects of the utility model are: (1) structure is simple, and be easy to manufacture, cost is low; (2) practical, can according to thickness of wall body, the length of adjustment split bolt; (3) reusable, reduce construction cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is top view of the present utility model;
Fig. 3 is the zoomed-in view to pull bar of the present utility model;
In figure: construction formwork 1, to pull bar 2, sleeve pipe 3, clamp nut 4, joint ring 5, sealing piece 6.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described.
In the drawings, length-adjustable construction formwork of the present utility model to drawing device primarily of construction formwork 1, form pull bar 2, sleeve pipe 3, clamp nut 4, joint ring 5, sealing piece 6.
Described device comprises construction formwork 1, to pull bar 2, sleeve pipe 3, clamp nut 4, described sleeve pipe 3 is placed in the middle of two construction formworks 1, described pull bar 2 to be fixedly connected with sleeve pipe 3 through construction formwork 1, the described end to pull bar 2 is provided with clamp nut 4, described clamp nut 4 and be provided with joint ring 5 between pull bar 2.The centre of described sleeve pipe 3 is fixedly connected with sealing piece 6.Described sleeve pipe 3 and pull bar 2 is threaded connection.Described clamp nut 4 is buttferfly-type nut.Described sleeve pipe 3 quantity is 3.
Length-adjustable construction formwork of the present utility model, to drawing device, adjusts sleeve pipe 3 and the length to pull bar 2 according to the thickness of body of wall during use, thus reduces building costs.
