Abstract

A MULTI-PLACE FORM FOR MANUFACTURING PRODUCTS FROM CONCRETE MIXTURES containing movable longitudinal and transverse boards installed in the guards of the tray, connected by a mezkdu as a stripping tool, characterized in that, in order to facilitate the demolition of products with a complex configuration of lateral faces, the bumpers with the complex configuration of the lateral beams, which in order to conveniently dismantle products with a complex configuration of the lateral edges, they also have a stripping device, which is designed so as to conveniently dismantle products with a complex configuration of lateral edges. lugs in contact with one of the longitudinal sides made of a composite of separate sections, the number of which is equal to the number of molding compartments.

The invention relates to the manufacture of precast concrete and reinforced concrete products. The known form for the manufacture of concrete products containing a pallet, sliding sides and a stripping device J. The disadvantages of this form are the design complexity and the greater labor intensity of operation. Closest to the offer is a multi-part form for the manufacture of products from concrete mixes, containing movable longitudinal and transverse beams installed in the guide pallets, interconnected by a stripping device G2 3-. . The disadvantage of this form is the need to make single-piece removal of products with a complex configuration of side edges, which complicates the process of stripping. The purpose of the invention is the convenience of dismantling products with a complex configuration of side faces. This goal is achieved by the fact that in multi-seat form for the manufacture of products from concrete mixtures, with movable longitudinal and transverse boards installed in the pallet guide, interconnected by a stripping tool, the transversal boards are fitted with wedge supports in contact with one of the longitudinal sides , made of a composite of separate sections, the number of which are equal to the number of molding compartments. FIG. Figure 1 shows schematically the proposed multi-site form for the manufacture of products from concrete mixtures, a plan view; in FIG. 2, node I in FIG. one; in fig. 3 is a section A-A in FIG. 2} in FIG. 4 — node II in FIG. one; in fig. 5 is a section BB in FIG. The multi-sided form for the manufacture of products from concrete mixes consists of a pallet 1 connected by hinges 2 with a tailgate 3, guiding 4 types of dovetail, mounted on a pallet, on which mobile driving longitudinal 5 and transverse 6 boards are mounted, interconnected by stripping devices 7. In the original position, the longitudinal bead 5 is fixed with locks 8, the transverse beams 6 - with the stripping devices 7, and the flap section 3 - with wedges 9, rigidly mounted on the transverse beads 6. Each The stripping device 7 is made in the form of a slider 10 disposed parallel to the transverse sides 6 in the guides 11 of the pallet 1 and pivotally connected to the intermediate links 12 in the form of levers 13, connected in turn with the transverse flange 6. The slider 10 is hinged connected with the longitudinal side 5 axis 14 through the longitudinal groove 15, located in parallel. the axes of the guides 11 in the bracket, 16 of the longitudinal bead 5. The groove 15 is necessary for separating the start of dismantling of the longitudinal bead 5 and the transverse beads 6 in time. Formed. . the product may have a complex configuration of the end surfaces where the reinforcement is located. The multi-part form for the manufacture of products of concrete mixtures works as follows. A form is supplied to the formwork station (not shown), where the pallet 1 is fixed and the locks 8 of the longitudinal side 5 are opened, after which the dismantling devices 7 are opened, which are from 1; the lateral edges 6 start to whine; the maximum effort of the dismantling mechanisms is necessary at the moment of the side shift, and with the further course of the board it drops significantly. Therefore, when moving the longitudinal bead 5 to a stroke equal to the length of the groove 15, the force to open it changes during the time from maximum to minimum. At this moment, the axis 14 occupies the extreme position in the groove 15 of the bracket 16. The further opening of the longitudinal bead 5 provides its kinematic connection through the slider 10 and the levers 13 with the pilot side 6, which also begins to move in parallel from the product. The moment of displacement of the transverse flanges 6 on the pallet 1 is determined by the specific predetermined length of the grooves 15. Where the groove 15 is shorter, the transverse flanges 6, kinematically connected with this groove 15, are also shifted back and forth.
