SU94728A1 - Device for pulling pins from a concrete product - Google Patents

Description

The invention relates to devices that mechanize the manufacture of prestressed concrete products, and mainly plates, in the case when the reinforcement is pulled on punker tubes attached to the pins attached to the shield of the mold, and ethn gnter is pulled out of the concrete product after hardening the concrete, transferring on him the effort of tensioning the armature.

The device, according to the invention, is intended for shanizatsii, the operation of pulling the pin from the product after me curing the concrete. In this device for the installation of simultaneous worn out all or subsoil I ntyren | Dn reIlella sstem duntirovannyh on the full frame wedges, acting on the tongues by abutment in the mcnt form and in the tail part of the n 1tyre at the relative displacement of the pallet with the item and the product and the item and the tail part of the n 1tire, with a relative displacement of the pallet with the product and the product and the trailer and the tail part of the n 1 type, with a relative displacement of the pallet with the product and the product and the trailer in the tail part of the n 1 type, with a relative movement of the pallet with the product and the product and the trailer in the tail section of the n 1 type and with the movement of the pallet with the product and the product and the trailer. mi along its ployostn.

In addition to speeding up the process of pulling out the pins, the proposed device can eliminate :, favorable overvoltages of concrete anchors to the concrete, get rid of with successive vytakspvaI and gty.

The drawing shows an exemplary diagram of a device according to the invention: FIG. 1 - side view; fpg 2-plan; FIG. 3-facade.

The device is installed on the foundation of the railroad track on the track of the track1 and the iodine-tedezhk from the steam chambers on the warehouse of finished products. It is a metal frame with, in its order, installed a /, which can be lifted rpynna.ni or all together in the working position in the .MOHUi p1mch ;; / have such a form (Fig. 2, 3), with. with which they cover the tail part of the plugs 2, resting against the pallet of the form n in the projections of the tail part of the 1-plugs. The wedge can move on the horizontal rods of the mechanism.

The process of pulling out the pins is as follows. The subpipe 3, with the product 4 located on it, is hammered by means of jacks through an installed wedge system, which squeezes the trolley noddop carriage down, resting one side against the bottom and the surface of the iodon ear, the other - in the IIJTblr 2. 2. 2. of the tubes 6 embedded in the concrete, on which the reinforcement has been wound. When pulling the pins out of the tubes 6, the tension of the reinforcement is transferred to the concrete of the product, thereby performing a precarious situation in it.

After pulling out the product from the product, the latter is fed to the finished carriage noddon cart.

1. Device for pulling nggyri from reinforced concrete ed., Which serve to support reinforcement in the atomic state n1P1 until the concrete hardens, about t.: I am determined by the fact that, as a matter of fact, the foam of simultaneous n10 pulling out all of the groups or groups of groups, or all groups, or nygrs, mounted on a common frame of wedges acting on the plugs by abutting the shield of the form and the tail part of the wedge at relative change), shaping the shape or noddon with the product and the frame with the clamp along the bottom of the frame.

2. Device but also. 1, characterized in that the clip is mounted on a fixed frame at the help of swivel rods, which raise the wedge into working position for interaction with H1tyr in a variable over the frame of products.
