The invention relates to installations for the manufacture of large-sized building panels in an upright position.

The purpose of the invention is to increase production efficiency and reduce energy consumption.

FIG. Figure 1 shows schematically a part of an installation for the vertical production of large-size 2Q concrete panels, top view; in fig. 2 - continuation of the installation, plan view; in fig. 3 shows section A-A in FIG. one; in fig. 4 is a view B in FIG. one; in fig. 5 - the same plan view; in fig. 6 is a view B 25 of FIG. four.

Installation 1 (Fig. 1) is located in the closed factory shop 2 (Fig. 3). The longitudinal supports 3 and 4 support the supporting structures 5 of the roof 6 with the ventilating device 7 and the roof 8. On the console 9 and 10 of the supports 3 and 4 there are crane girders 11 and 12 of the bridge crane 13 located at the end of the workshop (indicated dash-dotted line-, with it) and controlled from the cabin 14. Another bridge crane 15 is located in the front part of the workshop where the process of manufacturing the building elements begins (Fig. 1). The installation also has 40 movable tanks 16 and 17 for supplying concrete mix, which can be moved transversely relative to the longitudinal axis of the workshop along the track 18 (Fig. 3). Along 45 workshops and in parallel one another is installed. Three cassette forms 19-21 have the same construction. Consider it on the example of cassette formwork 21. It contains formwork boards 22 and 23, rigidly mounted on movable bases 24 and 25, moved with the help of rollers 26 and 27.

Between the formwork boards 22 and 23 on the track 28, a 5 movable middle element 29 is installed, having a T-shaped structure, the horizontal crossbar of which is a pallet 30 - the carrier of the lower formwork

whoa. On the pallet 30, along a longitudinal axis of the pan, a vertical partitioning board 31 is rigidly fixed to produce two building panels in a vertical position in a cassette formwork at the same time. The cassette forms 19 and 20 (Fig. 3) are in the closed position, and 21 in the open position. The rails 28, 32 and 33 under the movable middle element 29 of the cluster formwork 21, 20 and 19 end at the horizontal transfer carriage 34 moving in the transverse direction and having rails 35 fixed on it, which join the rail tracks 28,32 and 33, extend them by allowing movement of the movable middle element from the cassette forms to the transfer cart and vice versa.

The transfer carriage 34 has a running gear 36 or 37, which can move along rails 38 laid under floor 39 of shop 2. The direction of movement is indicated by the double arrow G in FIG. one.

On the opposite side to the mobile platform 34, parallel to each other and the rail track 28,32 and 33, do not coincide with them, there are rail tracks 40 - 42 heat treatment stations, along which three insulation stations 43-45 respectively are installed along rail track 40 ; 46 - 48 along the rail track 41 and 49 - 51 along the rail track 45. The insulating stations of the rail tracks 40-42 are parallel to each other. Along the fourth rail (of the second route 52, there are posts for preparation, rolling out the movable middle element 29 for molding, namely, cleaning post 53, the first 54 and the second 55 preparation posts.

The rails 40-42 end at the second transfer carriage 56, which is located parallel to the first transfer carriage 34 and is made in the same way as it. Direction dvizhe5164

No carriage 56 is shown with a double arrow D. Each insulation station consists (Fig. 4) of symmetrically arranged rail tracks 40 - 42 posts for heat treatment of two insulation plates 57 and 58, suspended on racks 59 - 62 by means of pairs of hinged upper arms 63, 64 and 65.66, as well as the lower 67.68 and 69.70, with the levers 68 and 70 located behind the levers 67 and 69 (Fig. 4X) Each pair of upper and lower levers together with the uprights and insulating plates form articulated parallelograms, action from prizod (not shown), providing transverse per the insulation plates 57 and 58 are relative to rail tracks 40 or 41, or 42 heat treatment stations to ensure that they are adjacent to the outer sides of the building panels on the mobile middle element 29 on the heat treatment station or their removal. Each insulation plate, for example, 58 ( Fig. 5 and 6), is made of a rigid frame 71 (Fig. 6), consisting of parallel long 72 and 73 and short 74 and 75 elements, which are also parallel with each other. To increase stiffness, there are several elements 76-78 arranged parallel to elements 74 and 75 and interconnecting elements 72 and 73. The outer shorter frame elements 74 and 75 have upper 79.80 and lower 81,82 brackets, to which are pivotally attached respectively the ends of the levers 65.66 and 67.68. A stiffening sheet 83 is attached to the rigid frame 71, which on its other side is covered with a layer 84 of insulating material, for example solid polyurethane. Stationary crane tracks 85 are located along the shop, and at its end, platform 86 is provided for the storage of construction panels.

The installation operates according to the flow method with a given tact, according to which three cassette forms 19 - 21 are loaded with a concrete mass, heated and spalled. This is illustrated by the example of cassette formwork 19, therefore in FIG. 1 transfer cart 34 is located in front of this cassette formwork. After completion of molding in cassette formwork 19, two newly formed and brought to stripping strength construction

5 42 of the heat treatment station and placed in the insulation station 45 furthest from the cassette formwork, then the insulation station 44 is loaded and, finally, the insulation station 43, which is closed immediately after the element 29 is placed in them. The insulation plates 57 and 58 move towards each other by means of pairs of articulated levers 63.64 and 69.70, respectively, and 65.66 and 69.70, up to the contact of their layers 84 of insulating material with the outer side of freshly shaped building blocks 87. In the insulating stations, the following occurs e hardening without heating panels. The hardened building panels 87 on the movable middle elements 29 arrive at the front of the exact trolley 56. Then they are removed by an overhead crane 13 and frozen in the storage platform 86, from where they are shipped by vehicles (not shown).

Freed from the construction panels, the movable middle elements 29 of the cluster formwork arrive at the rail track 52, where they are processed at the posts 53 - 55 of preparation for the subsequent molding.
