(54) FORM FOR MANUFACTURING CONSTRUCTION

one

The invention relates to the manufacture of building products from concrete and reinforced concrete.

Forms for the manufacture of building products are known, comprising a pallet, sided beams connected with Him, slinging devices and supporting devices for stacking 1.

Closest to the present invention is a form for the manufacture of building products, comprising a pallet with hinged sides, in guide sleeves of which support columns are mounted, which are installed in the slots of the fixed base pallet 2.

However, the support legs, which are freely located in the openings of the sides and grooves of the pallet brackets, are in contact with their surfaces during vibration during the compaction of the concrete mix and increase, thereby, the level of production noise.

In addition, the auto-locking brackets, rigidly mounted on the pallet in the envelope of the longitudinal bortosch, are not visible to the operator and this makes it difficult for him to work.

PRODUCTS

The purpose of the invention is ease of maintenance and noise reduction.

This goal is achieved by the fact that the form for the manufacture of construction products, containing a pallet with hinged sides, in guide bushings of which support columns are mounted, mounted in slots of brackets fixed on the pallet, are provided with profiled elastic elements fixed in two Russa, respectively, on guide bushings and racks that are made with sling. openings in the upper part and contacts with uyor at the bottom.

FIG. 1 shows a form on a roller 15; in fig. 2 - stand, incision; in fig. 3 - the same view from the side; in fig. 4 shows section A-A in FIG. 3 (cut on the rack forms installed in the stack); in fig. 5 - transport position of the form on the conveyor line of the conveyor line, section.

The form consists of a pallet 1, pivotally connected with it the longitudinal 2 and transverse 3 sides and supporting struts 4.

Claims (2)

The longitudinal beads 2 are provided with guide sleeves 5. The sleeves 5 and the uprights 4 are provided with profiled elastic elements 6 and 7, limiting the movement of the struts, and are arranged in two lines. The upper parts of the support pillars 4 are made with sling holes 8 and support plates 9, and the lower parts are provided with stops 10 in contact with the pallet 11 brackets. The stop 10 of the rack 4 in the free position protrudes beyond the limits of the pallet 1. An example of its use in a conveyor line. At the initial post, the form with the product is installed on the roller table and is supported by the pallet 1 on its rollers, while the racks 4 are fixed by profiled elastic elements 6 and 7 and the stops 10 of the racks 4 protrude beyond the pallet 1. This position of the rack 4 is occupied by the entire specified technical route. The movement of the form is carried out using a pusher (not shown). In this position, the form gets on the vibroplatform, the concrete mix is loaded and compacted. When the rack 4 vibrates due to the interaction of the elements 6 and 7, they are installed with a uniform gap relative to the sleeves 5 of the beads 2, which prevents the elements from colliding with each other. The mold with the molded product is transferred by a lifting device into a steam chamber for accelerated hardening. For this purpose, the vehicle is lowered with a frame onto the sides of the mold. When lifting, the levers turn and wind up into the lifting holes of 8 racks 4. With a further rise of the rack 4, they rise until the contact of the stop 10 with the brackets of the pallet 11, after which the mold is lifted. In the steam chamber, the mold is lowered onto the base or onto the surface of the uprights 4 of the previous mold. When the mold is installed on the previous one, a technological gap is formed between them. After the product has gained the necessary strength, the stack is disassembled by a known technique and the shape of the auto grab is fed to the original post line. Due to the proposed construction, the racks are used as supports for stacking the forms, for slinging the grip when moving the form with lifting means, and also can be used as a transport stop for moving the forms along the conveyor line. The combination of functions makes it possible to reduce the dimensions of the auto-gripping and associated equipment, such as steam chambers, to reduce the number of form elements and reduce their weight. At the same time, the slinging is placed upstairs in the zone accessible to the operator for review, which facilitates his work. The profiled elastic elements of the uprights provide a uniform perimeter clearance between the uprights and the side sleeves, which eliminates the collision of the metal parts of the forms at the time of vibro-compaction of the concrete mix, thereby reducing the level of production noise. Claims The form for the manufacture of building products, comprising a pallet with hinged sides, in guiding sleeves of which support columns are mounted, which are mounted in slots of brackets fixed on the pallet, characterized in that, for ease of maintenance and noise reduction, it is provided with shaped elastic elements fixed in two Russa, respectively, on guide bushes and racks, which are made with sling holes in the upper part and in contact with the pallet brackets s at the bottom.
