Description

Adjustable mezzanine

The present invention relates to a mezzanine provided with an extension system in all its components, which allows its placement in any suitable place as well as the change of location, being able to adapt the same structure to other architectural spaces without the need for masonry work or changes in the structure.

It has its field of application within the industry of auxiliary components of the construction and singularly in the auxiliary industry of the mezzanines.

In this sector of the technique, effective developments, specifically dedicated to the function in question, give rise to a system of simple installation, with low cost and technically appreciable results. The characteristics of the system presented in this invention are perfectly adapted to this concept, offering the state of the art a novel, simple, simple and highly economical manufacturing embodiment. Some models are known in this sector of the industry that do not bring to the state of the art the novel features proposed by the present invention. The state of the art provides fixed mezzanines, custom made according to the details of the location in which it is to be installed and another type of modular mezzanine consisting of fixed modules of preconceived sizes and that have to undergo an adaptation to the place at the time of its installation.

In the face of the novelties provided by the present invention, the known mezzanines have the following drawbacks: They cannot be reused for other sites, for which reason they must neglect the installed mezzanine and install a new one in the case of transfer to another place. Specialized staff is necessary

REPLACEMENT SHEET (RULE 26) to carry out the installation of known mezzanines. The cost of transporting these conventional mezzanines is higher than that proposed by the present invention, since it entails the use of trucks of sufficient length to accommodate the components necessarily of fixed measures. It takes more time for installation. The modular mezzanines being constituted by modules attached to each other, have a lower firmness than those proposed by the present invention. They are less versatile. Its installation is complicated. They are accompanied by masonry works.

It implies the displacement of an operator to take measurements of the location where the mezzanine should be located with the consequent economic cost. The manufacture of these conventional mezzanines because it is necessary to produce them in units is significantly more expensive than those proposed by this invention. For the same reason an adequate stock cannot be available, assuming a dilation of the service time.

The present invention relates to a mezzanine comprising a floor surface extended on beams supported by pillars that is characterized in that: at least one pillar is composed of an upper part of the pillar and a lower part of the pillar inserted into each other with telescopic relationship, where the lower part of the abutment has at least two perforations of the lower part and the upper part of the abutment has at least two perforations of the upper part positioned coincidentally to join both parts by means of a pin; at least one beam is composed of beam pieces inserted into each other with a telescopic relationship and having beam perforations that coincide in both pieces for joining;

REPLACEMENT SHEET (RULE 26) and the pillar at its upper end has a capital, whose beam clamping face has perforations of the capital that coincide with the perforations of the beam to join the beam to the pillar. In a preferred embodiment, the mezzanine comprises at least two assemblies each formed by two pillars joined by the beam held by the capital, said assemblies are joined together by a joist composed of pieces inserted into each other with a telescopic relationship and which they have perforations that coincide in both pieces for their union. Said joist incorporates at each of its ends a beam-to-joist connector that has a beam face to the beam and a connector face attached to the joist with the corresponding beam-to-joist perforations that coincide respectively with perforations of the beam. beam and perforations of the joist for joining said assemblies.

In another preferred embodiment, the mezzanine comprises at least four pillars, at least two beams and at least two joists.

Faced with the drawbacks described above, the present invention provides the state of the art with innovative, simple and easy-to-use solutions that result in the following advantages: They can be reused for other locations, it being not necessary to neglect the installed mezzanine and install a new in the case of transfer to another place. No specialized personnel are necessary to carry out the installation of the mezzanine proposed by the present invention. The cost of transport is lower than that of conventional mezzanines, since the use of large vehicles is not necessary. The time dedicated to its installation is significantly less. The firmness offered by the mezzanine proposed by the present invention is

REPLACEMENT SHEET (RULE 26) superior to that offered by modular mezzanines. It is more versatile. Its installation is not complicated. It is not accompanied by masonry works. It is not necessary to move an operator to take measurements of the location where the mezzanine should be located with the consequent economic savings. The manufacture has a lower cost to be able to manufacture in series, since the measurements of its components are always the same. For the same reason you can have an adequate stock, assuming a saving in service time.
