In our drawings it is given five recommendations for use of frameworks in the various purposes. They can be used at school, at the enterprise, in club, for exhibitions or to place on a wall any element of registration which besides is required to be changed often. Convenient and cheap designs for school and youth club, the enterprise and establishment can to be rationally used, certainly, and in house conditions.
In the beginning we will tell about bulletin board newspaper registration. As is shown in the top drawing, we establish a replaceable framework of necessary size from reek in the width 4-6 sm and thickness of 1,5-2 sm, having lapped them on corners. Round it it is beaten thin laths and so that on the one hand the lath was level with the basic lath, and on the other hand acted in comparison with it so forward that it was possible to lay on it a plate from polyfoam. Polyfoam can be fitted a colour paper or a fabric, and then to fix its plastic or metal latches between laths acting forward. If you do not want, that polyfoam it was visible in front, all design should be turned, as is specified on the left drawing. Then the big frame will be visible in all width. In drawing below on the right it is shown, how round or oval frameworks are made. .
Then frameworks are pasted over with a dense cardboard on which it is possible to paste in turn, for example, photos of a picture or decorative posters. For descriptive reasons in drawing the initial design which processing only has begun is presented, and this design looks impressively enough. Actually we should use basically only those laths which thickness does not exceed 2 see .
Thus the special attention should be turned on the pasted corners, which problem consists in strengthening a design of a framework which becomes fragile after its lateral aspect will be rounded off. In the beginning the framework is lapped on corners. Only after the framework will stick together also glue will harden, internal corners become stronger. If we want, that a framework it was visible from a face sheet, and we fix the photo chosen by us in a traditional manner, behind a framework, it is necessary to process a rasp and a fine-grained emery paper a framework inside, having rounded off it to the desirable form. .
In the third example (drawing in the middle at the left) it is possible to provide such framework in the form of a rectangle. In the right part of drawing it is clearly visible that connection on corners is made vnahlestku. That who hangs up posters or the similar materials, calculated that they can be changed, we recommend to attach to a wall a lath, using screws with shkantami (drawing in the middle on the right see), we bore through in a lath small apertures. Then we take the stoppers painted in different colours, through each of stoppers we punch a nail with which help it is possible to fix a material of any width on a lath. .
Certainly, it is not so pleasant, if on the repaired wall, posters or pictures which are hung up there not for ever, and only for some time will be pasted. Therefore we suggest to issue a wall surface as follows. Of thin laths (connected by merging) we make a framework, and it is screwed by its screws in in advance built in a wall plastic shkanty (drawing below at the left see). The area occupied with separate sites of this panel, should correspond to the usual sizes of posters that one big site or a little the small have always been in regular intervals closed. .
