SHOCK-ABSORBING STRUCTURE USING SUPPORTING PLATE PART FOR BUILDING BOTTOM}

The present invention relates to a buffer layer connection structure for a building floor, and to prevent the waterproof tape taped between the buffer layer from falling, as well as to improve the durability of the waterproof tape and to improve the structural stability of the buffer layer connecting portion, It relates to a buffer layer connection structure for the building floor used.

The buffer layer 40 of the building floor is formed on the concrete floor layer 10 of the building floor as shown in FIG. 1 or is formed on the light-bubble concrete layer 20 above the concrete floor layer 10.

The upper mortar layer 30 or the lightweight foam concrete layer 20 is located at the top.

The buffer layer 40 serves to block the floor impact sound by lowering the dynamic modulus.

With respect to the buffer layer 40, the inventors of the present invention have disclosed a 'dustproof rubber foam manufacturing method and a dustproof rubber foam prepared therefrom' (Korea Patent Publication No. 10-0504148) .

Such a technique improves the buffering effect by lowering the vibration transfer rate by mixing a plurality of materials in a state in which it is difficult to thicken the floor thickness sufficiently, such as an apartment house.

The buffer layer 40 is arranged on the concrete floor layer 10 by adjoining a plurality of them in the horizontal direction.

As a technique related to the construction method of the buffer layer 40, using the joint member, such as tape 50, the buffer layer 40 is connected to each other 'connected floor impact sound shock absorbing material of the multi-family apartment building' (Korea) Utility Model Registration No. 20-0420631) has been published.

Looking at the design as described above, it can be seen that the tape 50 is connected to each other as shown in FIG.

By the way, the buffer layer 40 is formed of a material having elasticity in nature, when the local compressive force is applied to one side of the buffer layer 40 connected to each other, the local settlement deformation occurs in the portion where the compressive force is applied.

That is, compressive deformation occurs in the buffer layer 40 due to the compressive load generated while the worker moves for the work in the state of laying several buffer layers 40 adjacent to each other, which results in deterioration of taping workability. There was a problem.

In addition, if the local compressive force is repeatedly applied due to the person coming and going in the workplace even after the taping operation, there was a problem that the tape 50 falls from the buffer layer 40.

As such, when the tapes 50 connecting the buffer layers 40 to each other fall, the buffer layer 40 becomes an environment in which moisture can penetrate.

In particular, in view of the fact that the buffer layer 40 is formed of a large amount of foaming material, the buffer property is deteriorated due to the penetration of moisture into the buffer layer 40, or mold is formed on the buffer layer 40 and the concrete floor layer 10. Will cause problems such as.

The buffer layer connection structure for the building floor using the reinforcing plate of the present invention is to solve the problems occurring in the prior art as described above. It is to improve the stability of the taping by improving the stability of the tape by preventing the separated waterproof tape is separated and gaps are to be improved.

In addition, the support member is sandwiched between the buffer layers adjacent to each other at the piping portion, such that the buffer layer is not deformed in response to the compressive load of the upper portion at the buffer layer connection portion.

In order to solve the above problems, the buffer floor connection structure for the building floor using the reinforcing plate of the present invention is formed under the finishing mortar layer or the lightweight foam concrete layer and is configured to block the floor impact sound while supporting the upper load. A plurality of buffer layers whose outer peripheral surfaces are opposed to each other so as to be adjacent to each other; A waterproof tape attached to an upper surface of an adjacent buffer layer and configured to prevent water from flowing from the top to the bottom; It is composed of a reinforcing plate is installed on the upper surface of the connecting portion of the adjacent buffer layer attached to the waterproof tape to distribute the load from the top;

A plurality of buffer layers formed on the bottom of the finishing mortar layer or the light-weight foam concrete layer and configured to block the floor impact sound while supporting the upper load, and having a gap apart from each other while being adjacent to each other; A pipe provided in a lower portion of the gap between the buffer layers; Is installed in the upper portion of the pipe, the upper surface and the support member which is located on the same line as the buffer layer and the upper surface; A waterproof tape attached to an upper surface of an adjacent buffer layer and configured to prevent water from flowing from the top to the bottom; Reinforcement plate is installed on the upper surface of the connecting portion of the adjacent buffer layer attached to the waterproof tape is configured to distribute the load from the top.

On the other hand, the reinforcing plate is formed from 1 to 3 kinds of polypropylene, polyvinyl chloride, polyethylene as a raw material, or pressurized wood powder molding plate with a binder, inorganic powder press molding plate with a binder, wood powder with a binder and It is characterized in that any one selected from the press-formed plate was formed by mixing the inorganic powder and press-molded.

In addition, the reinforcing plate is characterized in that any one of a single layer structure or a multi-layer structure.

According to the present invention, deformation of the buffer layer is suppressed when a compressive force is applied at the upper portion of the connection portion of the adjacent tapered buffer layer.

In addition, the waterproof tape attached to the buffer layer is prevented from being separated and openings can be improved to improve the stability of the tape to improve the waterproof performance.

In addition, by suppressing the deformation of the waterproof tape against the compressive load acting on the buffer layer adjacent to each other in the pipe portion to improve the stability of the waterproof tape to improve the waterproof performance.

Hereinafter, the buffer layer connection structure for the building floor using the reinforcing plate of the present invention will be described in detail with reference to the accompanying drawings.

The buffer layer connection structure for the building floor using the reinforcement plate of the present invention is formed under the finishing mortar layer 30 or the light-foamed concrete layer 20 and is configured to block the floor impact sound while supporting the upper load, and adjacent to each other. A plurality of buffer layers 100 whose outer peripheral surfaces are opposed to each other; A waterproof tape 300 attached to an upper surface of the adjacent buffer layer 100 and configured to prevent water from moving from the top to the bottom; Reinforcement plate 200 is installed on the upper surface of the connecting portion of the adjacent buffer layer 100 is attached to the waterproof tape 300 to distribute the load from the upper;

A plurality of buffer layers 100 formed under the finishing mortar layer 30 or the light-foamed concrete layer 20 and configured to block the bottom impact sound while supporting the upper load, and are spaced apart from each other while being adjacent to each other; A pipe 500 installed at a lower portion of the gap between the buffer layers 100; It is provided on the upper portion of the pipe 500, the upper surface and the support member 400 which is located on the same line as the buffer layer 100 and the upper surface; A waterproof tape 300 attached to an upper surface of the adjacent buffer layer 100 and configured to prevent water from flowing from the top to the bottom; Reinforcement plate 200 is installed on the upper surface of the connecting portion of the adjacent buffer layer 100 is attached to the waterproof tape 300 is to distribute the load from the upper;

In this case, the buffer layer 100 is deformed at the point corresponding to the connection part when the compressive load acts on the connection part of the buffer layer 100 adjacent to each other by installing the reinforcement plate 200 at the upper part connected by the waterproof tape 300. It will not be, which is why the waterproof tape 300 will not fall.

That is, it is possible to improve the waterproof performance by installing the reinforcing plate 200.

Hereinafter, each component of the present invention will be described in detail.

The buffer layer 100, which is a component of the present invention, is formed below the lightweight foam concrete layer 20, as shown in FIG. 1A, and is located on the concrete floor layer 10, or as shown in FIG. The lower mortar layer 30 may be positioned above the lightweight foamed concrete layer 20.

At this time, the preferred position of the buffer layer 100 is located in the lower portion of the lightweight foam concrete layer 20, as shown in Figure 1 (A) is configured to support the lightweight foam concrete layer 20 or the finishing mortar layer 30 of the upper portion. It is desirable to be.

In this case, the buffer layer 100 is preferably foamed using natural rubber or synthetic rubber as a raw material, or foamed from a mixed material of natural rubber and synthetic rubber as a raw material in order to block the floor impact sound.

In addition, a foamed product can be used as a raw material of polyurethane, polyolefin, polyethylene, polypropylene, polyvinyl chloride, ethylene vinyl acetate, or a mixture of two to six kinds thereof.

In addition, a polyester nonwoven fabric may be used as the buffer layer 100.

The structure of the buffer layer 100 may be formed in one foam form, or may be a structure in which a plurality of buffer materials are stacked, a support plate is installed at an upper portion, or a heat insulating material is installed at a lower portion thereof.

For example, the support plate may be installed on the upper portion, and the buffer layer 100 having one foam-type buffer mounted thereon may be applied.

In this case, the buffer member may be formed in a flat plate shape, and may form a buffer protrusion of a shape spaced apart from each other on the top or bottom.

When the buffer protrusion is installed, the vibration blocking effect is improved because the coefficient of elasticity of the entire buffer layer 100 is lowered.

In addition, it is also possible to install a heat insulating material in the lower part, which is to prevent the heat insulating performance is lowered when installing the buffer projection spaced apart from each other by installing the heat insulating material in the bottom to satisfy the heat insulating performance by blocking the heat rising from the concrete floor layer (10). Let's go.

The buffer layers 100 adjacent to each other are preferably opposed to each other as illustrated in FIGS. 4 and 5, but are not limited thereto, and may be provided to have a gap apart from each other as illustrated in FIG. 6.

In this case, as shown in FIG. 6, the pipe 500 may be installed in the gaps spaced apart from each other, and the support member 400 may be installed above the pipe 500.

At this time, the upper surface of the support member 400 is preferably located on the same line as the upper surface of the buffer layer (100).

In addition, the lower portion of the support member 400 is preferably formed in a rounded shape so that the cross section coincides with the outer circumferential surface of the round pipe 500.

In addition, the support member 400 to be applied at this time, it is preferable to use the foamed by using natural rubber or synthetic rubber as a raw material, or to use the foamed by using a mixed material of natural rubber and synthetic rubber as a raw material.

In addition, a foamed product can be used as a raw material of polyurethane, polyolefin, polyethylene, polypropylene, polyvinyl chloride, ethylene vinyl acetate, or a mixture of two to six kinds thereof.

In addition, a polyester nonwoven fabric may be used as the support member 400.

The support member 400 is preferably formed of the same material as the buffer layer 100 described above.

This is to prevent twisting of the member by forming the same material to have the same thermal volume expansion rate and shrinkage rate.

The waterproof tape 300, which is a component of the present invention, is attached to the upper surfaces of the connection portions of the plurality of buffer layers 100 so as to prevent water from moving from the top to the buffer layer 100 and the bottom thereof.

The waterproof tape 300 may use a waterproof tape 300 made of a known water-insoluble material that is insoluble in water.

In addition, it is preferable to use a strong adhesive force to structurally fix the waterproof and the adjacent buffer layer (100).

Reinforcing plate 200 is a component of the present invention is installed on the upper portion of the buffer layer 100 is attached to the waterproof tape 300 is to protect the buffer layer 100 around the upper load.

As the reinforcing plate 200 is installed, the deformation of the buffer layer 100 is very small due to the load generated when the worker steps on the buffer layer 100 after the construction of the buffer layer 100.

That is, since the buffer layer 100 is not deformed, after the waterproof tape 300 is attached and dried, a contraction deformation does not occur even when a worker applies a load to the connection portion of the buffer layer 100 when the worker moves from the upper portion of the buffer layer 100. It will not be so that the waterproof tape 300 is not dropped or separated.

As a result, the waterproof performance of the entire buffer layer 100 is improved.

That is, the conventional buffer layer 100 shrinks downward at the boundary of the buffer layer due to the compressive load of the connecting portion, so that it is difficult to attach the waterproof tape 300 well. The waterproof performance could not be improved, but the present invention solves this problem.

The reinforcing plate 200 serves as a pedestal of the finishing mortar layer 30 or the lightweight foam concrete layer, in particular, the lightweight foam concrete layer 20, which has a weak mechanical strength, as well as the buffer layer 100 due to the compression load of the connection part. In order to prevent depression, it can be formed from various materials, and it is preferable to form it with a high strength member.

To this end, the reinforcing plate 200 may be formed using one or three kinds of polypropylene, polyvinyl chloride, and polyethylene as raw materials.

In addition, it may be formed of any one selected from plywood, a pressurized molding plate to which a binder is added, a pressurized molding plate to which a binder is added, a pressurized molding plate to which a binder is added, and a powdered wood powder and an inorganic powder. have.

At this time, the thickness of the reinforcing plate 200 is preferably formed to a thickness between 0.5 mm to 5 mm.

If it is thinner than 0.5 mm, not only the supporting function is deteriorated, but also local deformation occurs, so that the upper load cannot be supported well.

In addition, when the thickness is thicker than 5 mm, a problem occurs that the thickness of the foamed concrete layer 30 of the upper portion becomes thin, and economic efficiency is lowered.

The reinforcing plate 200 should be kept as thin as possible while keeping the thickness as thin as possible, and should also consider economics.

Therefore, although it may be formed in the form of a general flat plate, it is more preferable to form in the form of a multi-wall having a column using a member of high strength.

The flat plate portion is formed at the upper and lower portions, and the wall portion is formed in the form of a multi-walled portion therebetween, so that even if an expensive member having a high strength is used, less material is added to enable a high economical member.

At this time, the shape of the wall portion may be formed in a straight line, a triangle, a quadrangle, a polygon such as a hexagon, a cylinder, or the like in addition to the lattice shape to further improve the structural strength.

Referring to the construction method of the buffer floor connection structure for the building floor using the reinforcing plate of the present invention configured as described above are as follows.

Referring to the installation of the buffer layer 100 to form a structure as shown in FIG. 4, first, a plurality of buffer layers 100 are placed adjacent to each other on top of the concrete floor layer 10 or the lightweight foam concrete layer 20.

Then, the waterproofing tape 300 is attached to the upper portion of each of the buffer layers 100 to which the buffer layers 100 are fixed to each other.

Then, by installing the reinforcing plate 200 on the upper portion of the waterproof tape 300, the connection construction of the series of buffer layers 100 is completed.

On the other hand, as another construction example, a plurality of buffer layers 100 on the top of the concrete floor layer 10 or lightweight foam concrete layer 20 is adjacent to each other in the pipe 500 and disposed to give a gap.

Then insert the support member 400 on the top.

After the installation of the support member 400 is completed by attaching the waterproof tape 300 to the upper portion of the connection portion of the buffer layer 100, and then install the reinforcement plate 200 thereon, the connection construction of the series of buffer layers 100 is finished. .

According to the configuration as described above, even if a load occurs in the connection portion to which each buffer layer 100 is connected, the compression deformation does not occur.

Therefore, even after the waterproof tape 300 is attached to the connection portion, the waterproof tape 300 does not fall well, thereby improving waterproof performance.

As described above, the building buffer layer having a hollow part of the present invention described above is not only used for the floor structure, but may be applied to various parts such as vibration blocking of a mechanical structure.
