Description

Floor structure

The present invention relates to a floor structure, and more particularly, to a floor structure that enables horizontal installation of a plurality of shock absorbers arranged in a lattice shape on the upper side of a floor slab of a building.

Recently, with the development of industrial technology and the improvement of the standard of living, the demand for preventing or reducing inter-floor noise in apartment houses has increased greatly, and accordingly, various products, methods and devices capable of dampening shock and noise have been developed. Is becoming.

For example, Korean Patent Registration No. 10-1792467 "Shock and Noise Attenuation Device" previously filed by the applicant is disclosed. The prior art is an elastic member composed of a plurality of elastic chips gathered; An elastic container compressing and holding the elastic member; It includes; a shock absorber installed on the upper side of the elastic container to be caught by a locking portion formed along the circumferential direction, preventing the elastic member from leaking to the upper side, and transmitting shock applied from the upper side to the elastic member. The shock absorber includes a belt-shaped flange installed to be caught under the engaging portion; A pillar portion formed upward along the circumferential direction inside the flange; A cover portion covering the pillar portion so as to have a plurality of openings; A plurality of second pillars formed upward along the circumferential direction of each of the plurality of openings; A plurality of second cover portion covering the upper side of each of the plurality of second pillar portions; including, the cover portion and / and the second cover portion shock and noise reduction device characterized in that a plurality of air holes are formed ( As related to claim 1), the structure of the shock absorber of the shock and noise reduction device is improved to simplify the structure, thereby reducing manufacturing cost, increasing structural stability, reducing noise, and as much elasticity as possible in a low height space. An object of the present invention is to provide a shock and noise damping device capable of securing sufficient and soft elastic force by sufficiently compressing and filling the chips.

However, the floor slab of the building constructing the prior art has irregularities or inclinations due to construction errors, crushing or sagging due to use, and the like.

Therefore, when the prior art shock absorbers are arranged and installed on the floor slab of the building in a lattice shape, the installation height of each shock absorber is different. Accordingly, the support installed on the upper side and the upper plate cannot be evenly supported, so that the impact reduction effect cannot be properly achieved, and there is a problem in that noise is generated due to uneven support.

In addition, in order to level the height of the shock absorbers arranged in a lattice shape, when installing the support plates of a certain thickness on the lower side of the shock absorbers, there is a minimum height of the support plates, so it is difficult to completely level the height of the shock absorbers, and the shock dampers Since the device and the base plate are not fixed to the floor slab, the base plates cannot be released and function as time passes, and there is a problem in that another noise is generated by the base plate.

In addition, when it is desired to pour mortar on the upper side of the floor slab to level it, it takes a long time for the mortar to be cured, and particularly, a mortar of a thin portion of the poured mortar is crushed and falls off the floor slab. There is this.

Therefore, it is required to develop a floor structure capable of quickly installing a shock absorber horizontally by correcting irregularities or inclinations of a floor slab of a building at low cost.

The smooth layer 30 may be applied to the entire upper side of the floor slab 1 having irregularities or inclinations to level the upper piece. The smooth layer 30 may be composed of one or more of sand, martha and aggregate. That is, the smooth layer 30 may be composed of sand, martha, aggregate, or a mixture of them. In the case where the aggregate or sand is mixed with the aggregate, the support force is increased by filling the voids between the aggregate or the sand, and the damage due to friction between the aggregates can be prevented. In the case of aggregate, an increase in weight can be reduced by using lightweight aggregate. It is preferable that the size of the aggregate is about 10 mm or less.

Sand, martha, aggregate, etc. constituting the smoothing layer 30 are used as they are without a binder. Therefore, when the smooth layer 30 is formed by using sand, martha, aggregate, etc., the irregularities or inclinations of the floor slab 1 can be corrected and leveled. That is, it can be completed by horizontally arranging after applying the floor slab 1 on which unevenness, etc. is formed, for sand, martha, aggregate, and the like. Therefore, the smoothing layer 30 can form the unevenness of the floor slab 1 horizontally at a quick and low cost compared to using a conventional method such as a base plate or mortar.

A cover layer 40 may be provided above the smoothing layer 30. The cover layer 40 may prevent the smooth layer 30 from being moved or discharged. In addition, the cover layer 40 may prevent local depressions in the smooth layer 30.

Can be prevented. For this purpose, it is preferable that the cover layer 40 has appropriate rigidity. The cover layer 40 may be composed of plywood, wood board, PVC board, gypsum board board, magnesium board board or iron board.

A moisture-proof paper 10 such as vinyl or PVC may be installed between the floor slab 1 of the building and the smooth layer 30. The moisture-proof paper 10 can prevent moisture and the like that may be generated on the floor slab 1 of the building from seeping into the smooth layer 30. The moisture-proof paper 10 prevents moisture or the like from permeating into the smoothing layer 30, thereby maintaining a good state of the smoothing layer 30, thereby preventing local settlement and depression of the smoothing layer 30.

The circumferential edge of the moisture-proof paper 10 is folded upward and may be coupled to the cover layer 40 by adhesion or the like. That is, the moisture-proof paper 10 can seal the smoothing layer 30 together with the cover layer 40, thereby preventing the smoothing layer 30 from being detached from sand, mass, and the like, and at the same time, preventing leakage of dust and the like.

The shock absorbers 5 may be disposed on the upper side of the cover layer 40 in a lattice shape. The shock absorbers 5 can absorb shock or vibration applied from the upper side. The shock absorber 5 may be composed of an elastic member composed of a plurality of elastic chips, an elastic container compressing and holding the elastic member, and an impact absorber capable of covering the upper side of the elastic container and preventing leakage of the elastic member. . The shock absorbers 5 are provided on the upper side of the cover plate, thereby minimizing noise generation.

Referring to Figure 2, the floor structure according to another example of the present invention, in the floor structure to level the installation height of the shock absorber (5) installed on the upper floor slab (1) of the building, irregularities are formed or Containers 20 with an inclined side and are arranged in a lattice shape on the upper side of the floor slab 1 of the non-horizontal building; A smoothing layer 30 composed of at least one of sand, martha, and aggregate filled in each of the containers 20; It is installed to cover the upper side of the smoothing layer 30 and consists of plywood, wood board, PVC board, gypsum board board, magnesium board board, or iron board to suppress movement or discharge of the smooth layer 30 and prevent local depression. The cover layer 40; It may be disposed on the upper side of the cover layer 40, shock absorbing device (5) for absorbing shock or vibration applied from the upper side.

In the present embodiment and the embodiments described below, the same parts as the above-described embodiments may be omitted. The omitted part can be applied by analogy with the description of the above-described embodiment.

The present embodiment may include containers 20 which are arranged in a grid shape on the floor slab 1 of a non-horizontal building in which irregularities are formed or inclined. The containers 20 may have an upper side open. That is, the containers 20 of the present embodiment may be disposed under each of the shock absorbers 5 arranged in a lattice shape. The container 20 may be formed of a material such as iron, wood, plastic, rubber. It is appropriate that the container 20 can support the smoothing layer 30 described later with respect to the pressure applied from the shock absorbing device 5. Therefore, it is preferable to increase the thickness of rubber or the like compared to iron or the like. The container 20 may have a flat size or a larger size than the impact damping device 5 enters. The container 20 may be formed in a square shape or a circular shape. The container 20 is preferably formed to fit the shape of the shock absorbing device 5 installed on the upper side.

Inside the container 20, a smooth layer 30 composed of at least one of sand, martha, and aggregate may be formed. That is, the smoothing layer 30 of the present embodiment is filled in the inside of each container 20, so that the material can be saved compared to the above-described example applied to the entire surface of the bottom slab 1.

A cover layer 40 may be formed above the smoothing layer 30. The cover layer 40 may inhibit movement or discharge of the smoothing layer 30 and prevent depression of the smoothing layer 30. The cover layer 40 may be composed of one of plywood, wood board, PVC board, gypsum board board, magnesium board board, or iron board in the same manner as in the above-described embodiment. The cover layer 40 may be installed in a shape that covers the smooth layer 30 from the inside of the container 20. The installation height of the shock absorbers 5 can be quickly and easily adjusted by adjusting the amount of input of sand, martha, etc., which is a material of the smooth layer 30.

The container 20 may be coated with rubber, synthetic resin, silicone, etc. on its lower surface. The coating prevents the container 20 from slipping on the upper side of the floor slab 1 and reduces noise that may occur between the container 20 and the floor slab 1.

In addition, the lower surface of the container 20 may form a protrusion protruding in the horizontal direction. The protruding portion secures stability by increasing the area in contact with the floor slab 1 of the building, and at the same time, it can be fixed to the floor slab 1 with screws, pieces, or the like in the protruding portion.

When the container 20 is disposed on the floor slab 1 as in the embodiment described later in this embodiment, it is possible to secure a larger arrangement space such as an electric wire or a water pipe.

Referring to Figure 3, the floor structure according to another example of the present invention, in the floor structure to level the installation height of the shock absorber (5) installed on the upper floor slab (1) of the building, the irregularities are formed Containers 20 having a rectangular shape and having an inclined shape and disposed on the upper side of the floor slab 1 of the non-horizontal building, the upper side being open; A smoothing layer 30 composed of at least one of sand, martha, and aggregate filled in each of the containers 20; It is installed to cover the upper side of the smoothing layer 30 and consists of plywood, wood board, PVC board, gypsum board board, magnesium board board, or iron board to suppress movement or discharge of the smooth layer 30 and prevent local depression. The cover layer 40; It may include; shock-absorbing devices (5) are disposed at regular intervals on the upper side of the cover layer 40 to absorb the shock or vibration applied from the upper side.

This embodiment is installed on the upper side of the floor slab 1 of the building, and may include containers 20 having a rectangular shape and an upper side open. Each of the containers 20 may support a plurality of impact damping devices 5 installed in a line. Therefore, the shock absorbers 5 arranged in a grid shape can be supported by the containers 20 arranged in a plurality of rows. In this embodiment, the number of containers 20 can be reduced by supporting a plurality of impact damping devices 5 by one rectangular container 20, thereby increasing work efficiency. The container 20 may be formed of a material such as steel, wood, plastic, rubber. The container 20 is suitable to have a strength sufficient to support the smoothing layer 30 to be described later with respect to the pressure applied from the plurality of impact damping devices 5 installed on the upper side thereof.

Inside the container 20, a smooth layer 30 composed of at least one of sand, martha, and aggregate may be formed. That is, the smoothing layer 30 of this embodiment is filled only on the inside of each container 20, so that material can be saved compared to the example applied to the entire surface of the floor slab 1.

A cover layer 40 may be formed above the smoothing layer 30. The cover layer 40 can prevent movement or discharge of the smoothing layer 30 and prevent local depression of the smoothing layer 30. The cover layer 40 may be composed of one of plywood, wood board, PVC board, gypsum board board, magnesium board board, or iron board in the same manner as in the above-described embodiment. The cover layer 40 may be installed in a shape that covers the entire smooth layer 30 from the inside of the rectangular container 20. On the upper side of the cover layer 40, a plurality of impact damping devices 5 are installed to be spaced apart at regular intervals, thereby forming a floor structure capable of minimizing noise generation. The installation height of the shock absorbers 5 can be adjusted very easily by adjusting the input amount of sand, massa, etc., which is a material of the smooth layer 30. That is, by installing the smoothing layer 30 obliquely on the rectangular container 20 installed on the inclined floor, that is, applying the thickening layer 30 thickly at a deep depth, and smoothing layer 30 at a shallow depth It can be easily formed horizontally by applying thinly.

Rubber, synthetic resin, silicone, and the like may be coated on the lower surface of the rectangular container 20. This coating prevents the container 20 from slipping on the upper side of the floor slab 1 and reduces the noise that may occur between the container 20 and the floor slab 1.

In addition, the lower surface of the container 20 may form a protrusion protruding in the horizontal direction. The protruding portion secures stability by increasing the area in contact with the floor slab 1 of the building, and at the same time, it can be fixed to the floor slab 1 with screws, pieces, or the like in the protruding portion.

The container 20 may be provided with a separation plate 22 separating the middle at regular intervals. That is, the separation plate 22 for separating the inner space of the container 20 at regular intervals is provided in the middle to prevent the container 20 from opening, so that the shock absorbing device 5 can be well supported.

In addition, the container 20 may be formed of a pair of b-shaped angle. That is, the container 20 may be formed by installing a pair of b-shaped angles parallel to each other at regular intervals on the upper side of the floor slab 1. A pair of b-shaped angles, one side of the flange is coupled to the bottom slab 1 with screws, pieces, etc., so that the other pair of flanges can form a space in the shape of the container 20. The smooth layer 30 may be formed by injecting sand, martha, or the like into this space.

Between the pair of containers 20 formed of a pair of b-shaped angle c-shaped vinyl or PVC moisture-proof paper 10 can be installed. This U-shaped moisture-proof paper 10 can prevent leakage of sand, martha, and the like of the smooth layer 30.

The container 20 may be connected to each other in the longitudinal direction. That is, the protrusions protruding laterally at the end portions in the longitudinal direction of the container 20 are formed, and the protrusions can be connected to each other by coupling. This may allow the length of the standardized container 20 to be easily adjusted to the size of the floor slab 1.

The longitudinal connection of the container 20 can be performed in various ways, as shown in the figure.

In the above-described embodiments, an anti-rise key (not shown) may be installed on the upper side of the cover layer 40. That is, the cover layer 40 is coupled to the inner side of the wall 2 of the building or the inner side of the container 20 by screwing, bonding, or the like, while contacting the upper side of the cover layer 40 so that the cover layer 40 is on the upper side. It can prevent the soaring. Therefore, the smoothing layer 30 under the cover plate, which is pressurized by the shock absorbing device 5, is prevented from moving or leaking to other parts, so that the leveling of the smoothing layer 30 can be stably maintained.
