Sector of the technique to which the invention relates

The invention presented affects the Sector of Construction, having an industrial impact on the manufacture of tools and accessories for labor brickwork.

Background of the invention

The background in the field is very abundant of construction as it is well known that, both in Spain and in the most developed countries, the activities related to the Construction constitute the main engine of the economy. Throughout case the higher the degree of development of a larger country is also the shortage of labor and, consequently, they are very good received those solutions that save labor, and either based on mechanizing the construction processes, or based on improve the performance of all the activities involved in construction On the other hand in modern times not only attaches great importance to work performance and media efficiency employees but above all quality finishes are required for conform to current regulations.

Regarding the lifting of walls, partitions and walls of any kind there are classic means that based on the progressive control of the work as it goes advancing, for which alignments are drawn on the ground and leaves controlling verticality with the help of traditional plumbs or even optical plummets of laser beams. This implies a slowdown of the works or a defective finishing of the same at Do not be checked as often as necessary. Only the best ones professionals with a long experience in this type of work they achieve the required quality without reducing the overall performance. Is that is, in this field there are no great advances when it comes to a hard machinable operation. Notwithstanding the author of the present innovation, good connoisseur of this type of activities, brings a novelty that improves performance and quality of the partitioning and staking operations of door and window frames. The rule of the invention is of good quality, simple operation and very acceptable price for being insignificant with respect to the final value of the work where use.

Description of the invention

The present invention, as it has remained exposed in the introduction, refers to a tool masonry that is used as an auxiliary element prior to lifting partitions and walls of all kinds. That tool it is used at the same time as others identical in number that depends on the magnitude of the wall that you want to build. The moment of his use is the one in which the phase of main and forged structures, that is when it should be undertaken the phase of division of spaces based on lifting the partitions corresponding. To do this you must know the plans constructive figures contained in the project to determine the planned location for separating partitions.

As soon as the distribution is known according to plan, the rules of the invention are being followed, following the planned alignments and coining those rules between the ground and the ceiling. In a first approximation the rules must conform to a slightly higher than the one between the ground and the ceiling. To do this, the upper semi-rule slides over the lower one and is immobilized once the aforementioned dimension is reached, slightly greater than the height of ceilings. In a second and final phase, press the lower ruler on the ground to compress the spring helical existing in the base place the ruler in the location definitive and relax the tension on the spring so that the ruler It is wedged between the floor and the ceiling. The press operation The rule to compress the coil spring can be done with hands or with the foot, using an existing pedal to such effect. Then the operation is repeated with another rule and so successively until the wall layout is completed to lift up.

Replanted in this way each cloth, only subtract the construction of the partition based on and guiding themselves rules that in the end must be removed for use in another work.

Although the inventor prefers that the material of the Useful be stainless steel, do not rule out the use of others synthetic materials that can fulfill the desired function and allow a long life of the tool at hand.
