Abstract

Built in a workshop on the basis of forming respective upper and lower slots (11) and (12) in support members (10) close to the ends thereof, to allow the insertion of other front members (13), the width of which will depend on the spacing between said slots (11) and (12) as well as on the height of the bleachers to be built and, where it is desired to build a vertical wall, the slots (11) and (12) are located on the same vertical plane, with the height of the front members (13) having to be equal at least to the distance between the upper slot of the upper support member and the lower slot of the immediately superior support member and at the most equal to the distance between the upper slots of the two immediately contiguous support members located in different horizontal planes.

Description

The present Utility Model consists as indicated in the title thereof of a "A PREFABRICATED STRUCTURE FOR THE CONSTRUCTION OF BLEACHERS AND WALLS", the new construction features, shape and design whereof fulfil the purpose for which it has been specifically devised with maximum reliability and efficacy.
The increasing technological evolution of all industrial sectors obliges the procurement of items which, thanks to their constructive features, allow the construction of bleachers and retaining walls with relative simplicity which, without any doubt, will have an enormous influence on the building costs since the component items allow for prefabrication of all the members which will form the bleachers as such.
These bleachers are built with the use of a number of support members having a sustantially prismatic shape which will be located equidistantly at a distance depending logically on the features of the bleachers to be built.
The length of said members will also preferably depend on the type of land where they are to be assembled.
A slot has been formed in the front area of the said support members both on the upper surface and on the lower surface, the distance of said slots of the upper and lower surface of each of these support members being such as to agree with the width of the bleachers to be provided in each case, all the support members being located on one same horizontal plane, allowing the location of the front members which will be located perpendicularly to the support members, being perfectly lodged thanks to the upper slots of the said support members, the perfect positioning thereof being ensured by the assembly at the top end of the front members of another series of support members, said front members being located thanks to the lower slots.
Thus, in view of the distance between the upper and lower slots of the support members, the desired width for each of the passages of the corresponding bleachers may be obtained.
Once the support members and front members have been assembled, it will be sufficient to locate the corresponding slabs which will then form the seats of each of these bleachers.
Obviously, with this structure there is obtained a very simple construction which at the same time allows advantage to be taken of the irregularities of the land and this way the bleachers as such becomes a retaining wall.
Furthermore, thanks to this same configuration, it is sufficient to form the upper and the lower slots of the support members at the rear end of the bleachers in the same vertical plane whereby to obtain a completely vertical wall with the application of the front members or a stepped wall if the upper and lower slots are not situated on the same vertical plane, it being obviously possible to adopt any desired slope, simply by modifying the distance between the upper and lower slots of each of the support members on each of the surfaces.
Also, it should be considered that leaving a certain degree of play in the slots allows the front members to adopt a certain degree of inclination whereby it is very easy to obtain any desired curve for the bleachers which have been built or the desired retaining wall.
Other details and features of this Model will become evident during the following description, in which reference is made to the drawings accompanying this specification in which, schematically, there are shown the preferred details. These details are given as an example, with reference to one possible embodiment, but are not limited to the details given herein; therefore this description should be considered from an illustrative point of view without any limitations.

Figure no. 1 is an elevation view in cross section showing the arrangement of the different members forming the bleachers.
Figure no. 2 is a plan view, partly in cross section, of bleachers built with the object of this Utility Model.
Figure no. 3 is a schematic illustration of bleachers which have been built with a certain degree of curvature.
Figure no. 4 is a schematic detail showing bleachers terminating in a vertical wall, the rear portion of the bleachers forming also a vertical wall.
Figure no. 5 shows schematically double bleachers built with the object of this registration.

As may be seen in the enclosed figures, the prefabricated structure for building bleachers of this Utility Model is formed basically by support members (10) which adopt a configuration in which there has been formed in the upper surface a slot (11) while there is provided a further slot (12) of equal characteristics to (11) in the lower portion of the same support member.
The slots (11) and (12) formed in the upper and lower surface of the support member (10) are separated depending on the type of bleachers to be built, all these support members (10) being located in one same horizontal plane, with the peculiarity that the distance between each of these support members (10) as well as the length thereof will depend on the type of land where they are built.
Into the slot (11) of the support members there will be fitted the front members (13), the positioning thereof being aided by the slots (12) of the support members located on the upper plane, thereby obtaining a stepped configuration which as mentioned, will depend on the distance between the slots (11) and (12) of each of the support members.
Logically the front members have a gap of the same size as the distance between the upper slot and the top of the same support member (10), thereby obtaining a perfect finish.
Once the support members (10) and the front members (13) have been placed in position, it is then sufficient to mount the slabs (14) which will have the size required for their perfect positioning, thereby providing the bleachers as such.
As may be understood, with this structure it is sufficient for slots (11) and (12) of each of the support members to be placed on one same vertical line so as to be able to obtain a perfectly vertical retaining wall as may be the case shown in figure no. 4.
It may be also considered that with the front members (13) having a certain play relative to the slots (11) and (12), bleachers having a particular curvature may be built, making the structure highly versatile.
It will be understood after seeing the drawings and the explanation given thereof that the Model of the present specification provides a simple, effective construction which may be reduced to practice with great ease, constituting without any doubt an industrial result.
It is stated, for the pertinent effects, that there may be introduced into the object of the present Model all those variations and modifications of detail which the circumstances and practice may advise, provided that with the variations introduced, the essence as summarized in the following CLAIMS is not altered or modified.
