Description

Buried box structure

The present invention relates to a structure of a buried box, and more particularly, a communication box that connects various communication lines as well as an electric box (distribution box, distribution box, etc.) of a method buried in a concrete wall, or a fire box equipped with fire fighting equipment, etc. It relates to an improved burial box structure so that it can be buried smoothly and stably without the need for a separate bracing means while enduring the pouring pressure of concrete regardless of the standard by improving the structure of the burial box.

In general, it detects the voltage state supplied to the load with a power distributor that distributes and supplies electric power supplied to households as well as industrial uses to various loads, and quickly cuts off electricity when abnormal conditions such as a short circuit occur, resulting in a safety accident caused by electricity It is equipped with a distribution board or distribution box in which various devices are installed, such as a ground leakage circuit breaker to prevent an electrical leakage in advance, a wiring circuit breaker that selectively cuts off electricity only to the side with an abnormality, and a watt-hour meter that measures the total amount of power used for a certain period of time.

The distribution board is usually installed inside the distribution box buried in the wall when a building is constructed, and it enables selective electricity supply control as needed, and at the same time makes management and maintenance convenient.

In the same way, electric boxes collectively referred to as distribution boxes, communication boxes in which communication lines are routed, and fire boxes equipped with firefighting facilities are all buried in the wall.

In order to embed these burial boxes in the wall, the concrete mortar is poured and cured after positioning and temporarily fixing the location before pouring the wall concrete.

However, since the buried box is a rectangular box-shaped box 20 having an open part 10 with one side open, as in the example of FIG. 1 , when the concrete mortar is poured while temporarily fixed as it is, the external pressure increases. As the circumferential surface, the back surface, etc. are pushed toward the inside of the empty enclosure 20, the deformation is induced, which leads to poor burial.

In order to solve this problem, conventionally, a plurality of splints are installed inside the opening 10 to prevent dents. However, since splints must be installed separately for every operation, it is a lot of work and cumbersome, and a separate splint material is consumed and the cost is also high. It costs a lot.

In addition, it is difficult to prepare all the splints that meet the standards because the enclosure 20 of the burial box has a very diverse standard, so it is difficult to prepare all the splints that meet the standard, and it takes a lot of work and costs a lot.

Hereinafter, preferred embodiments according to the present invention will be described in more detail with reference to the accompanying drawings.

Prior to the description of the present invention, the following specific structural or functional descriptions are only exemplified for the purpose of describing embodiments according to the concept of the present invention, and embodiments according to the concept of the present invention may be implemented in various forms, It should not be construed as being limited to the embodiments described herein.

In addition, since the embodiment according to the concept of the present invention may have various changes and may have various forms, specific embodiments are illustrated in the drawings and described in detail herein. However, this is not intended to limit the embodiments according to the concept of the present invention to a specific disclosed form, and it should be understood to include all modifications, equivalents and substitutes included in the spirit and scope of the present invention.

Buried box according to the present invention, as illustrated in FIGS. 2 and 3 , includes a box body 100 .

The box body 100 is the same as in the prior art as a rectangular box shape having an open portion 110 with one side open.

However, in the present invention, the circumferential surface and the rear surface of the ship body 100 are configured to have a curvature.

At this time, the curvature has an outwardly convex shape.

However, it does not have a curvature up to the inner wall surface of the ship body 100, the inner wall surface is made vertically and horizontally, and only the outer wall surface is formed to have a convex curvature in the form of a girdle.

As applied to the main core form, the center of each side of the circumferential surface and the center of the surface of the back side have the thickest thickness, and the thickness becomes thinner toward the edge so that the arch principle (the principle of reducing the load by distributing the pressing force to the side) is applied. It provides the advantage of being able to withstand sufficiently without installing a separate splint inside the body 100 by increasing the resistance to (the force of the concrete mortar pushing).

However, it is not possible to increase the resistance by forming the curvature to be large, and if the curvature exceeds a certain level, depression due to stress concentration may be induced, so the following conditions must be satisfied.

In the present invention, the circumferential surface (four sides) and the curvature of the rear surface of the ship body 100 are set differently, because the front of the rear surface is empty as the opening 110, so a stronger resistance is required. That is, the curvature of the back surface should be greater.

Then, the circumferential surface will be defined as the first curved surface 120 , and the rear surface will be defined as the second curved surface 130 .

At this time, the first curved surface 120 is designed to have a curvature that maintains C: 4.1 mm, P: 2.6 mm, and E: 1.1 mm, as shown in the figure below.

Here, C is the thickness of the center of each surface among the circumferential surfaces, P is the thickness at a point 20mm away from C, and E means the thickness at a point 35mm away from C. However, it is not an edge part and all have the same thickness after point E.

In the same concept, the second curved surface 130 is designed to have a curvature that maintains C: 4.5 mm, P: 2.9 mm, and E: 1.1 mm.

In addition, in the present invention, in particular, the rear surface, that is, the second curved surface 130, the forming unit 140 can be further implemented.

In this case, the forming part 140 may be both a protrusion type (embossed) protruding in a semicircular shape or a concave type (intaglio) concave in a semicircular shape.

In particular, as shown in the example of FIG. 4 , the forming unit 140 may be configured such that the horizontal forming unit 142 and the vertical forming unit 144 cross each other to have a grid shape.

This forming unit 140 is made by forming processing, and further strengthens the durability of the up, down, left and right around the formed point.

Therefore, the forming portion 140 is not limited to only the rear surface of the box body 100, of course, may also be formed on the circumferential surface.

In addition, in the present invention, it may further include a foam sheet (200, see FIG. 3) having a humidity control function to suppress the occurrence of dew condensation inside the ship body 100.

The foam sheet 200 may be provided by pressing the groove portion 104 on the inner wall surface 102 of the housing body 100 and attaching it to the groove portion 104 .

In particular, it is preferable that the foam sheet 200 has moisture control properties so that dew condensation does not occur.

To this end, the foam sheet 200 is a composition consisting of 25% by weight of Allophane powder, 5% by weight of Antimony doped Tin Oxide (ATO), 10% by weight of hydrocolloid and the remaining polyethylene resin in a foam type. Use what is made of sheets.

At this time, the allopen powder is a porous allopen clay mineral that is pulverized to have a particle size of 0.01 mm or less and pulverized. Allopen is a clay mineral generated in the process of weathering of volcanic ash and does not have an exceptionally crystalline structure, so-called amorphous. It is clay. It is reported that it is easy to combine with corrosion, which is an organic colloidal particle, and has an excellent ability to absorb and remove formaldehyde, the cause of sick house syndrome.

In particular, allophene is known to have an excellent moisture control function because it consists of porous fine particles. It is reported that it has 15 times the absorption and moisture absorption ability of the commonly known moisture control wallpaper, so this characteristic can be actively used in the present invention. make use of

Here, humidity control is a property of being both dry and wet, and it is easy to understand if you consider it as a representative example. That is, when the humidity rises, it absorbs moisture to prevent dew condensation, and when the humidity goes down, it releases the retained moisture to control the humidity.

And, the ATO contributes to the securing of thermal insulation and heat shielding performance, and the hydrocolloid is added to form a gel and maintain the wet state to confirm the adhesion for a long time to strengthen the adhesion.

Through this, when moisture is generated, the foam sheet 200 absorbs moisture, and when it is too dry, moisture is released to automatically adjust so that dew condensation does not occur inside.

Accordingly, it is also possible to obtain an effect of preventing the occurrence of problems due to the occurrence of dew condensation in advance.
