Description

(54) FORM PALLET

i

The invention relates to the development of concrete and reinforced concrete structures by immediate stripping.

Known portable pallet containing the bottom with the frame stiffness. The pallets with molded products are vato-loaded and loaded into large steaming trays, in which for this purpose storage racks with IJ auto-compression brackets are installed.

However, these pallets can be used to produce d-shaped products of the same height, which is possible only at specialized factories, for example, for manufacturing hollow flooring. Each steaming chamber is also equipped with only one pallet size. When forming various sizes of products of a wide range on these pallets, a lot of Russian loading into chambers becomes impossible.

Also known is a portable pallet containing a bottom with glasses rigidly attached to it and support elements hinged in the glasses.

However, these pallets can be used to form only one product of constant height.

The purpose of the invention is to improve operational capabilities.

This goal is achieved by the fact that the pallet includes a bottom with glasses rigidly fixed on it and supporting elements pivotally mounted in the glasses, the latter made in the form of pivoting telescopic struts and equipped with fixtures for fixing them in a vertical position.

In addition, the fixture for fixing each support element is made in the form of two restrictive straps fixed in parallel on the glass to the glass. ,

Fig, 1 shows a pallet with a different position of the brackets, a general view; in fig. 2 - packaging of pallets with molded products, different in height, side view; in fig. 3 shows the structure of the support post and its attachment to FIG. 4 - section A-A and FIG. 3 in FIG. 5 - packaging of pallets after stripping of products, side view.

Claims (2)

The pallet contains a frame 1 stiffness and a metal sheet 2 connected to it, which serves as the bottom. On the bottom tray 2 of the pallet are pivotally mounted telescopic supports, consisting of the lower part in the form of a glass 3 and the upper support element 4, which is freely placed in the cavity of the glass 3. The glass 3 is attached to the bottom 2 of the hinge. The hinge consists of two brackets 5, made with vertical slots 6, in which the axle 7 of the cup 3 is mounted. In the upper part of the cup 3 there is an axial through hole 8 for passing the locking pin 9, by means of which the height-adjustable is adjusted, the support stand For holding the locking pin 9 in the axial hole 8. During the vibration compaction of the concrete and when packing the pallets in the steaming chambers, a clamp 10 is attached to the cup 3, which. into the grooved groove at: the end of the finger 9. The supporting element 4 freely makes vertical shuffles in the cavity of the glass 3, which allows adjusting the height of the supporting column. At the reference end, the supporting element is from de {whale head 11, at the other - an open vertical slot 12, which allows it to pass through the axis 7 and touch the gap 2. Between the ends, the supporting element 4 contains scgoe & 1 axial holes 13, through the shaft The working positions are held by the locking clamp 9. To eliminate the spontaneous tilting of the support column when palletizing pallets with molded articles in heat treatment chambers, the hinge is completed with a device for fixing it in a vertical position / from the upper tube. wise an element 14 rigidly attached to the upper lateral edges; /) of the brackets 5, and a lower thrust element 15, also attached rigidly to the lower lateral edges of the brackets 5 and the spacing 2. The supporting stand, which is brought into a vertical position, cannot tilt itself spontaneously Since the glass 3 is not raised from the bottom 2 to the height of the lower thrust element 15, and turning it in the opposite direction does not allow the thrust element 14 to be made. As a result, the angle of rotation of the support column is 90. Pallet works following them BrAZ. On the subdong installed on the vibrating table, removable forms of the Oez bottoms made with technological slopes are placed, filled with concrete mix and subjected to vibro-compaction, after which the forms are removed from the molded products. The support stands on the pallet are placed in a vertical position by turning them about axis 7, (Mountain element 4 with the help of locking pin 9 and through in it and glass 3 axial holes 13 and B are adjusted accordingly to the height of the shaped part.) the pallet is by the lifting loops 16 and transported with molded products in the chamber {% 1 steaming. The next pallet with the molded products is mounted on the supporting posts of the lower pallet, the alsot of the supporting posts is adjusted This makes it possible to package oddons in many ways with molded products of various sizes, which is very important for unprepared precast concrete plants, whose nomenclature is significant and in turn often often quantified. and the pallets are removed from the paring tank and installed on the cleaning and lubricating station. Their support legs are horizontalized, which makes it possible during storage under ones prop up on each upper support brackets {garnish -resistant underlying tray, as shown in fyg. 5. It gives the opportunity to use the volume of production tasks. Claim 1. Pallets of molds for the manufacture of building products with immediate dismantling, inclusions of bottom with glasses rigidly fixed on it and supporting elements iarnirovanyi installed in the glasses, characterized in that, in order to expand operational capabilities, the supporting elements are made in the form of rotary, s a vertical plane of telescopic racks, each of which is provided with a device for fixing it in a vertical position. 2. A pallet according to claim 1, characterized in that the fixture for fixing the support element is made in the form of two parallel limiting strips that are located in the same vertical plane and rigidly fastened to the glass.
