Description

Modular prefabricated log cabinet for electrical and telephone channels.

Field of the Invention

The invention falls within the sector industrial manufacturing of boxes, making equal parts of repeated or serial form; performing his mission when he performs the assembly of them in civil works that have underground electrical and / or telephone pipes.

Background of the invention

The existence of the Arquette as such and its application in the field of underground facilities, is something already known and used for a long time by all Companies in the sector. Even the majority of companies in electrical distribution and telephony have standardized dimensions that must be used in their facilities.

However, regarding the execution technique of them, as well as the materials used, We found a wide range of solutions:

The most common are those executed directly in the work or in the same place where they are to be located to carry out its function; performing on a brick basis, cement coating or plastering of the inner faces and frame metal embedded in upper face to accommodate the lid. These they present inconveniences of high times; both execution as of labor to perform them; as well as frequent mistakes or  dimensional deficiencies in its finish.

Another solution existing in the market are those executed by formwork with metal parts or wood, resulting uncomfortable execution on site by the weight of the formwork parts, as well as the need to vibrate Poured concrete for filling holes.

They are also of the type prefabricated, but in plastic material type P.V.C .; which they have advantages such as weight, durability over time high resistance to moisture and corrosive agents of this material, are supplied with the dimensions standardized by the companies and have gaps to introduce the Incoming and outgoing pipes or tubes. They present as inconvenient its fragility in the face of the mechanical demands to which Sometimes they are subjected to construction work.

Within the prefabricated type, also there are those made of reinforced concrete, but executed in only one piece; which makes them very heavy elements for its transport and workability on site.

Description of the invention

The invention that concerns us, gives it two main advantages to the configuration of boxes; in the case of the elements that generally form the derivations and junction nodes in the underground electrical pipes and telephone

First, it is important to note that the configuration of the finished cassette, will occur in the final location of the work or installation where necessary your service; getting it by overlapping union in height of several individual modules; being this one of the main characteristics that define the invention.

The previous feature makes it defined as a modular chest and gives the advantage to the set of be composed of several smaller pieces, getting better workability on site, less weight and ease of transport.

Each module of the commented ones consists of a hollow quadrangular piece, which is executed at the factory by mold and the materials with which they are made are vibrated concrete and inclusion inside a metal reinforcement of corrugated steel. The thicknesses of its four faces will have a variable thickness in function of the final dimensions of it; because at Increase the size of the casket or inner hollow, you must increase said thickness so that the resistance of is.

The setting between each of the modules during its vertical stacking is done by butt joint between the smooth surface of its edges, holding together by itself weight and thus achieving its tightness with respect to surrounding terrain or any other foreign body.

Really, each module is like a ring quadrangular that allows its easy vertical stacking on site by part of the operator as already explained; favoring from this way the attainment of the final casket intended with reduced execution times and ease of assembly.

The second feature or advantage that is defends in this invention, it is the system to favor the entrance of the tubes that rush to the casket. To do this, in the four faces of each module described, a thickness reduction is performed commented, whose motive is to facilitate the breakage of the cloth concrete where each pipe of the installation rushes. Through this system is feasible the reception of the tubes by any of the four faces of which the casket consists, as well as indifferently at the arrival height of the tubes, providing of as many holes as modules have been necessary to mount for Compose the chest.

After the introduction of the tubes, the entire insert must be sealed with a mixture to confer the necessary tightness, preventing the entry of water and small rodents that can damage power lines and / or telephone

Too; the thickness recesses described with which each module counts on each of its four faces, favor the manipulation of these by the operator, due to that produce edges and steps in its exterior finish, which facilitates its grip and better adjustment in the assembly process by vertical stacking until height or depth is achieved necessary of the casket.

Formation of the casket

The place where the caves finally perform its task will always be the works that have the corresponding underground pipes for which have projected their use. Once done in the ground the excavation or cabin that houses them, will proceed to the assembly of the boxes in said recess.

Prior to field placement of first module of which the casket will be constituted, will be necessary the conditioning or leveling of the base or bottom, which it is usually done with the provision of a slight gravel layer, which serves as a leveling element as well as drainage, to prevent water from accumulating inside and allowing it to seep into the ground.

On the previous one, the first module is placed taking care of its correct leveling and applying a small layer of cement mortar on the joint that forms with the base of the ground. Later, so many modules are added in height prefabricated as necessary to the desired level that it is generally the level of road or steel, making sure in everything moment that are well focused on each other. TO then the different cloths are broken where the introduction of the pipes that rush it; introducing these and sealing said joints with some type of insulating mixture.

Finally, all the land is filled outer perimeter of the casket and is compacted, which gives it the stability and rigidity necessary to the whole. As top closure the casting frame and cover are placed, using the approved by the different existing supply companies in the market.

Brief description of the drawings

For a better understanding of what was written up Now in this Description of the invention document, accompany some drawings where, by way of example, the configuration of the intended cassette for registration of electrical and / or telephone installations, even reflecting the tubes that rush it.

In Figure 1 a 3D perspective of each piece or precast concrete module, by which and by stacking in height the set is formed of the casket in question, consisting of a hollow quadrangular cube (1) of concrete vibrated and obtained in mold, equipped with reinforcement metal inside (2) based on corrugated steel and with a thickness recess (3) on each of its four faces to favor their breakage where you should undertake each tube.

Figure 2 is a section of the assembly of the mounted casket, consisting of three precast concrete modules (A) stacked in height, where the lower module rests on the own terrain or a thin layer of engraving (B) that does the functions bottom and drainage of the casket before possible accumulations of water inside. Also appreciated are the pipes (C) that rush inside the box (in this case two units), introduced previous breakage of the cloths or thickness recesses (D) of each face where the tube rushes and at the corresponding height. One time introduced the tube through the hole, the joint is sealed with material insulator (E).
