Description
Technical Field
The utility model relates to the technical field of building construction, in particular to a step-by-step tightening device.
Background
In the present building industry, the fastening piece used as a building template support is a common building construction tool. The most common step-by-step tightening devices currently consist of a guide bar and a metal clip, wherein the guide bar is formed by an elongated flat iron, one end of which is bent, the other end of which is engaged with the metal clip, and the lower end of the metal clip is slightly bent and engaged with the guide bar through a hole provided at the upper end thereof. When the locking device is used, the bayonet surrounded by the bent end of the guide bar and the metal card is surrounded outside the casting box body, then the metal card is knocked to move forwards to realize the tight jacking fixation of the template, the guide bar and the metal card are self-locked under the action of friction force and the tensioning force of the template to prevent automatic loosening, and the principle of friction force and lever is mainly utilized. In the process of striking the metal clamp by the small hammer, the metal clamp is easy to be damaged in steps, is easy to deform and has insufficient firmness in use, and certain inconvenience is brought to the construction of staff. After the step by step is finished, the guide bar and the metal card are smashed by staff, and cannot be reused and can only be discarded as waste.
Therefore, it is very significant to research a step-by-step tightening device which is not easy to deform, higher in firmness and convenient to use.
Disclosure of Invention
The utility model aims to provide an improved step-by-step tightening device, which has the characteristics of difficult deformation, higher firmness and convenient use.
The utility model can be realized by the following technical scheme:
the utility model provides an improved generation step by step tight device, includes movable chuck, fixed chuck and guide arm, the guide arm is the bolt member that one end has the pole head nut, fixed chuck and movable chuck are rectangular steel pipe, and fixed chuck is less than movable chuck, and the chuck end welding of movable chuck has the chuck shrouding and opens there is the chuck hole, the perpendicular welding of chuck end side has first card pipe, the perpendicular welding of chuck end side of fixed chuck has second card pipe, the inside fixed fixation that is equipped with of card tail end.
When the movable clamp is used, the fixed clamp sleeve is inserted into the movable clamp, the building template is arranged between the first clamping pipe and the second clamping pipe, the guide rod penetrates through the clamp hole of the movable clamp (penetrates through the movable clamp) to be screwed into the fixed nut of the fixed clamp, and the movable clamp is tightened to the fixed clamp by rotating the guide rod through the rod head nut, so that the building template is clamped.
After the use is finished, before the template is removed, the step-by-step device is removed, the guide rod and the movable clamping head are loosened from the fixed clamping head by reversely rotating the guide rod through the rod head nut, and then the guide rod, the movable clamping head and the fixed clamping head are taken away from the template and used for the next time.
The utility model has the characteristics of simple structure, convenient use and repeated use.
Drawings
Fig. 1 is a schematic diagram of a component disassembly structure of the present utility model.
Fig. 2 is a schematic view of the combined use (partially cut-away) of the components of the present utility model.
Detailed Description
The utility model is further described below with reference to the accompanying drawings:
examples
Referring to fig. 1 and 2, an improved step-by-step tightening device comprises a movable chuck 1, a fixed chuck 2 and a guide rod 3, wherein the guide rod 3 is a bolt rod piece with a rod head nut 31 at one end, the fixed chuck 2 and the movable chuck 1 are rectangular steel pipes, the fixed chuck 2 is slightly smaller than the movable chuck 1, the chuck end of the movable chuck 1 is welded with a chuck sealing plate and provided with a chuck hole 10, the chuck end side is vertically welded with a first clamping pipe 11, the chuck end side of the fixed chuck 2 is vertically welded with a second clamping pipe 21, and a fixing nut 22 is fixedly arranged in the clamping tail end.
When in use, the fixed clamping head 2 is inserted into the movable clamping head 1, the building template is arranged between the first clamping pipe 11 and the second clamping pipe 21, the guide rod 3 passes through the clamping head hole 10 of the movable clamping head 1 (passes through the movable clamping head 1) and is screwed into the fixed nut 22 of the fixed clamping head 2, and the movable clamping head 1 is tightened to the fixed clamping head 2 by rotating the guide rod 3 through the rod head nut 31, so that the building template is clamped.
After the use, before the template is removed, the step-by-step device is removed, the guide rod 3 and the movable clamp head 1 are loosened from the fixed clamp head 2 by reversely rotating the guide rod 3 through the rod head nut 31, and then the guide rod 1, the movable clamp head 1 and the fixed clamp head 2 are taken out from the template and used for the next time.
