Description

I ... The invention relates to precast concrete production and may be used in the building materials industry. The known form for the manufacture of concrete products, including the pallet on which the trough-shaped boards are installed, with fixing elements; And petroleum formers l. However, in such a device it is impossible to form products whose mounting loops are removed from the board for some distance. In addition, it is difficult to fto design and because of the need to supply air to the chamber. The form is also known, which includes a pallet, sides, and an insert with looper | 2}. However, the assembly and demoulding of the mold is very laborious, moreover, in this mold it is not possible to mold products whose mounting hinges are removed from the board for a certain distance. 2 V The purpose of a vouroben is to reduce the laboriousness of molded products with hinged loops installed at an offset from the ends of the front end. This is achieved by having the tray equipped with brackets and loop-forming. The body is hinged on the brackets with the cMeitteHHM center of gravity in the station board, which is made with an emphasis for fixing the looper in the working position. FIG. 1 shows a plan form, a general view of FIG. 2 — node 1 in FIG. Ij in FIG. 3 - section А-А on fkg. 2} in FIG. 4 shows a section BB in FIG. 3. The form has a pallet 1, on which the flanges 2 are hingedly mounted and the insert 3 is rigidly fixed. On the grid 4 of the pallet 1, the brackets B are fixed, in which the looper 7 is mounted on the axis 6 for mounting loops. The center of gravity of the loop former 7 is shifted toward the bead 2, it is adjacent to the liner 3. In addition, the formation of the loop is placed in the liner 3 with an offset from the bead 2, which is made with an emphasis 8 for fixing the looper 7 in the working position. The device works as follows. After cleaning and lubrication of the mold on the pallet 1, the reinforcement with mounting loops is installed, in the liner 3 a looper 7 is installed and the beads 2 are closed; The stops 8 are in contact with the looper 7 {see Fig. 3, the initial position of the looper 7, and the stop 8, are shown by thin lines), fixing it in the working position. After this, the mold is filled with a concrete mass and is ready for heat treatment. When the form is dismantled, the latter is installed on the formwork post, the boards 2 are detached, while the stop 8 releases the former 7, which is rotated around the axis b under the action of weight and lowered, releasing the mounting loop 7 0. The product is removed from the mold. Then the cycle repeats. The formula for the manufacture of iron-tonnage products, including a pallet, sides and liner with a looper, is so that, in order to reduce the labor intensity when molding articles with mounting loops, the pallet is equipped with brackets, and the looper pivotally mounted on the bracket with an offset of the center of gravity towards the bead, which is made with an emphasis, for fixing the looper in the working position.
