the utility model provides a reinforcement auxiliary device for job site, includes door-shaped support, is connected with the cross arm that can go up and down through elevating system on the door-shaped support, and slidable mounting has the lifting hook that is used for hoisting the beam reinforcement on the cross arm.

Compared with the prior art, the utility model discloses a measuring method's advantage lies in:

the position of the cross arm is adjusted by the ascending or descending of the lifting mechanism, so that the reinforcement binding is assisted, the construction process of the beam plate part of the existing reinforced concrete structure is optimized, and the existing process is optimized into the support of the beam and the plate template → the binding of the beam reinforcement → the descending of the beam reinforcement → the binding of the plate reinforcement → the pouring of concrete; the requirement of cross operation of the template worker and the reinforcement worker on the same working face is reduced, the management intensity is reduced, the field safety of operators is improved, and the reinforcement binding process is improved.

Preferably, the technical solution of the present invention is as follows:

the lifting mechanism consists of a screw rod and a nut, the nut is clamped between two cross beams connected with the upright stanchions of the portal bracket, through holes for the screw rod to pass through are respectively arranged on the cross beams, the screw rod passes through the through holes and is connected with the nut through a threaded structure, and the lower end of the screw rod is fixedly connected with the cross arm; the structure is simple and easy to operate.

The two upright posts of the portal bracket are provided with slide rails, and the two ends of the cross arm are provided with slide grooves matched with the slide rails, so that a lead screw for limiting the lifting mechanism moves in the vertical direction, and the lead screw is prevented from rotating along with a nut.

The cross arm bottom is equipped with the slide, and the lifting hook upper end is equipped with the slider with slide complex for through adjusting make the lifting hook be located the upper portion muscle that will hoist and mount directly over.

The lower end of the door-shaped support is connected with the triangular base, so that the gravity center of the door-shaped support is reduced, and the stability of the device is enhanced.

Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments. It is to be understood that the following description is only for purposes of clearly illustrating the present invention and is not to be taken in a limiting sense.

Referring to fig. 1 to 3, a reinforcement auxiliary device for a construction site is shown, which is composed of a portal bracket 1, a lead screw 2, cross arms 4, a hook 5 and the like, wherein two vertical rods forming the portal bracket 1 are connected through two cross beams, the distance between the cross beams is equal to the thickness of a nut 3, through holes for the lead screw 2 to pass through are arranged at corresponding positions on the two cross beams, and the nut 3 is arranged at the through holes, so that the nut 3 is clamped between the two cross beams; the screw rod 2 penetrates through the through hole to be connected with the nut 3 through threads, and then is connected with the door-shaped support 1, and the nut 3 is limited in position, so that when the nut 3 is rotated, the screw rod 2 is lifted through movement of thread transmission between the screw rod and the nut.

The two upright posts of the portal bracket 1 are provided with slide rails 6, and the two ends of the cross arm 4 are respectively provided with slide grooves matched with the slide rails 6, so that the movement of the screw rod 2 is limited in the vertical direction and is prevented from rotating along with the nut 3; or, the sliding grooves are arranged on the inner sides of the two vertical rods of the door-shaped support 1, and the two ends of the cross arm are embedded into the sliding grooves, so that the same effect can be achieved.

The bottom of cross arm 4 is equipped with a pair of slide, and 5 upper ends of lifting hook are equipped with slide complex slider 7, and slider 7 can slide on the slide, adjusts the interval between lifting hook 5 through slip lifting hook 5 to the interval between the adaptation upper portion muscle makes the lifting hook be located directly over the upper portion muscle.
