Description

SHOCK-ABSORBING STRUCTURE INCREASING CONTACT AREA 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 connection area, It relates to an increased buffer layer connection structure for building floors.

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, and when the local compressive force of one side of the buffer layer 40 is applied, the local settlement deformation occurs at 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 floor connection structure for the building floor which has increased the contact area of the present invention is to solve the problems caused in the prior art as described above. To improve the workability of the taping operation.

In addition, the waterproof tape attached to the buffer layer is to prevent the separation and opening to improve the stability of the taping to improve the waterproof performance.

At this time, the deformation of the buffer layer is to be prevented by using a method of fitting the protrusion and the recess together.

This aims to simplify the connection process of the buffer layer and reduce the construction cost.

In order to solve the above problems, the buffer floor connection structure for the building floor which has increased the contact area 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. One side circumferential surface is formed with protrusions protruding outward from the top or the bottom, and the other bottom or top is formed with depressions recessed inwardly so as to be engaged with the protrusions, and a plurality of adjacent protrusions and depressions are engaged with each other. A buffer layer; It is attached to the upper surface of the connection portion of the buffer layer to be assembled to each other waterproof tape configured to prevent the water from moving from the top to the bottom.

At this time, it is attached to the side of the buffer layer, and the side waterproof portion having a waterproof material; It is attached to the bottom of the buffer layer, the lower waterproof portion having a waterproof material; is further installed, each buffer layer is characterized in that it is configured to have a protrusion and a depression in the state attached to the side waterproof portion and the lower waterproof portion.

In addition, the buffer layer is formed on the bottom of the finishing mortar layer or lightweight foam concrete layer and supporting plate to support the upper load; It is installed in the lower portion of the support plate and the shock absorbing portion to block the floor impact sound; characterized in that consisting of.

At this time, the buffer portion is formed in the lower portion of the support plate, a plurality of buffer projections to be spaced apart from each other to have a hollow portion inward; characterized in that consisting of.

In addition, the buffer portion and the buffer member formed on the lower support plate; It is formed on the upper or lower side of the cushioning material, spaced apart from each other with a plurality of buffer projections to have a hollow portion inward; characterized in that consisting of.

In addition, the insulating material for blocking the heat transmitted to the light-weight foam concrete layer or the concrete floor layer of the lower portion of the cushioning material; characterized in that is further installed.

On the other hand, the buffer layer is composed of a support formed on the bottom of the finishing mortar layer or lightweight foam concrete layer and a plurality of buffer protrusions formed on the upper or lower portion of the support and spaced apart from each other to have a hollow portion inward. It may also be characterized by consisting of a cushioning material to be supported by a lightweight foam concrete layer or concrete floor layer.

At this time, the lower portion of the cushioning material is formed, the heat insulating material to reduce the heat transfer between the concrete floor layer and the cushioning material; characterized in that is further installed.

In addition, the support plate for supporting the upper load is characterized in that the upper portion of the cushioning material is further installed.

In addition, the buffer layer may be characterized in that it is composed of multiple stacked.

According to the present invention, the workability of the taping operation is improved by suppressing the deformation of the buffer layer when the compressive force is applied to the connection portion of the adjacent buffer layer at the time of the taping operation.

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.

Hereinafter, with reference to the accompanying drawings for the building buffer floor connection structure to increase the contact area of the present invention will be described in detail.

The buffer layer connection structure for the building floor to increase the contact area of the present invention is formed on the bottom of the finishing mortar layer 30 or lightweight foam concrete layer 20 and is configured to block the floor impact sound while supporting the upper load, one side The circumferential surface is formed with a protrusion 110 protruding to the outside of the upper or lower portion, and the other lower portion or the upper portion is formed with a depression 120 recessed inwardly so as to be engaged with the protrusion 110. 110 and a plurality of buffer layer 100 is assembled with each other by engaging the recess 120; It is attached to the upper surface of the connection portion of the buffer layer 100 to be assembled to each other waterproof tape 200 configured to prevent the water from moving from the top to the bottom.

The feature is that the protrusions 110 and the depressions 120 each formed with each buffer layer 100 are connected to each other, so that when the compressive load is applied to the connection portion, the wall shape at the point corresponding to the connection portion is reduced, thereby waterproofing The tape 200 will not fall.

This structure simplifies the process while still improving waterproof performance.

In the present invention, the buffer layer 100 is formed below the lightweight foam concrete layer 20, as shown in Figure 1 (A), is located on the concrete floor layer 10, or as shown in Figure 1 (B) finish mortar layer The lower portion of the 30, it may be located 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.

The buffer layer 100 does not have a flat side structure as shown in FIG. 2 or FIG. 3, but as shown in FIG. 4, one side circumferential surface has a protrusion 110 protruding to the outside from the top or the bottom thereof, and the bottom of the other side. Alternatively, the upper portion is formed with a recessed portion 120 recessed inwardly to engage with the protrusion 110 so that the adjacent protrusion 110 and the recessed portion 120 are engaged with each other.

More specifically, in FIG. 4, the depression 120 is formed at the upper left side of the buffer layer 100, the protrusion 110 is formed at the lower side, the protrusion 110 at the upper right side, and the depression at the bottom. 120 is formed so that the protrusions 110 and the recesses 120 of the adjacent buffer layer 100 are engaged with each other.

After the protrusion 110 and the depression 120 of the buffer layer 100 are engaged, the waterproof tape 200 is attached to the upper portion of the connection portion as shown in FIGS. 4 and 5 (C).

The buffer layer 100 of FIG. 4 is an example having a flat bottom portion, and the buffer layer 100 of FIG. 5 is an example in which a plurality of buffer protrusions 102a are formed at the bottom thereof.

6 is a view comparing the conventional buffer layer connection structure and the buffer layer connection structure of the present invention.

Referring to FIG. 6A, when the edge of the buffer layer 100 is formed flat, the edge portion of the buffer layer 100 having elasticity is depressed when a load is applied to an upper portion of the connection portion. When the perimeter is recessed, the waterproof tape 200 attached to the upper portion is separated from the buffer layer 100.

When the waterproof tape 200 is separated, when the adhesion is incomplete due to the load of the worker moving on the buffer layer 100 during the installation of the buffer layer 100, the light-weight foam concrete at the top after the buffer layer 100 is installed When the worker's load is applied for the construction of the layer or the finishing mortar layer, the phenomenon in which the connection portion of the buffer layer 100 is repeatedly repeated may cause the waterproof tape 200 to fall off the adhesiveness.

When the waterproof tape 200 falls as described above, water penetrates into the buffer layer 100 from the upper finishing mortar layer or the light-foamed concrete layer, and eventually the buffering property deteriorates or the buffer layer 100, the concrete floor layer 10, or the light foam bubbles. It causes a problem such as forming a mold in the concrete layer (20).

Applicants have also proposed to install a reinforcing member or a supporting member in the connecting portion as a method for preventing this phenomenon.

However, this method not only takes work for constructing the reinforcing member or the supporting member, but also increases the production cost and increases the working time since the production cost of the reinforcing member or the supporting member is added.

However, when the buffer layer 100 is formed to be engaged with each other by forming the protrusion 110 and the depression 120 as shown in FIG. 6B, the contact area between the two buffer layers 100 even though the compressive load is applied at the top. As the total stress that resists the upper load increases, the degree of weakening becomes small even when the buffer layer 100 is not recessed or recessed at the connection portion between the two buffer layers 100.

As a result, the waterproof tape 200 does not fall well, and as a result, it is possible to ensure the waterproof performance in the buffer layer (100).

On the other hand, the buffer layer 100 of the present invention can be formed in a variety of structures.

First, the support plate 101 is formed on the bottom of the finishing mortar layer or lightweight foam concrete layer to support the upper load;

It is installed in the lower portion of the support plate 101 and the buffer portion to block the floor impact sound; can be configured as.

At this time, the buffer portion can also be configured in various ways,

A plurality of buffer protrusions 102a formed below the support plate 101 and spaced apart from each other to have hollow portions inwardly; , Or

A buffer member 102 formed below the support plate 101; It may be formed of a plurality of slow impactor (102a) is formed on the upper or lower buffer 102, spaced apart from each other to have a hollow portion inward.

In the above configuration, the heat insulating material 103 for blocking heat transmitted to the light-weight foam concrete layer 20 or the concrete floor layer 10 in the lower portion of the cushioning material 102; may be further installed.

As another configuration example of the buffer layer 100, the support part 102b is formed below the finishing mortar layer 30 or the light foamed concrete layer 20, and is formed on the upper part or the lower part of the support part 102b and spaced apart from each other. It is composed of a plurality of buffer protrusions (102a) to have a hollow portion inward, the lower portion of the buffer member 102 to be supported by a lightweight foam concrete layer 20 or concrete floor layer (10); .

At this time, it is also formed under the shock absorber 102, the heat insulating material 103 to reduce the heat transfer between the concrete floor layer and the shock absorbing material 102; may be further installed.

As another configuration example of the buffer layer 100, the buffer member 102 is formed under the finishing mortar layer 30 or lightweight foam concrete layer 20; A heat insulating material 103 formed of a lower portion of the buffer material 102 and composed of a plurality of buffer protrusions 102a spaced apart from each other to have a hollow portion inwardly, and a support portion 102b formed below the buffer protrusion 102a. It can also be configured as.

At this time, the support plate 101 for supporting the upper load may be additionally installed on the upper portion of the shock absorber (102).

In addition, the buffer layer 100 as described above may have a structure stacked in multiple up and down.

7 to 9 illustrate various embodiments of such a buffer layer 100.

In the case of FIG. 7A, the support plate 101 is provided in a configuration in which only the buffer material 102 is attached to the support plate 101 so as to attach the buffer material 102 having the cushioning performance. By preventing the collapse of the upper lightweight foam concrete layer or finishing mortar layer to prevent the phenomenon.

However, in the present invention, it is much more preferable to apply the configuration having the hollow portion and the buffer protrusion 102a as shown in FIGS. 7B to 8L rather than the configuration example of the buffer layer 100. .

In this configuration, the buffer protrusions 102a may be spaced apart from each other to have a hollow portion therebetween, thereby lowering the dynamic elastic modulus of the entire buffer layer 100 to improve vibration blocking performance.

By the way, the structure forming the hollow portion has a tendency to decrease the thermal elasticity coefficient of the entire buffer layer 100 while lowering the dynamic elastic modulus of the buffer layer 100 as a whole.

This phenomenon is due to the heat transfer by convection and radiation is transferred between the concrete bottom layer or the light-bubble concrete layer and the buffer layer 100 lower surface of the buffer layer 100 due to the buffer projection (102a) having a hollow portion to increase the heat permeability.

In order to solve this problem, as shown in (D) and (E) of Figure 7, (H) to (L) of Figure 8 to prevent the hollow portion from directly contacting the light-weight foam concrete layer or concrete floor layer of the lower ( 103) or a structure in which the buffer layer 100 is stacked up and down is preferably applied.

This structure, as well as the reduction of the dynamic modulus of elasticity by the hollow portion, by using the heat insulating material 103 or the upper and lower double structure lowers the heat transmission rate, it is possible to improve the thermal insulation.

The detailed description from FIG. 7A to FIG. 8L is as follows.

In FIG. 7A, a support plate 101 is formed at an upper portion thereof, and a buffer 102 is provided at a lower portion thereof.

7 (B) is a support plate 101 is formed on the upper portion, a strip bar form, a polygonal column or columnar, polygonal or upper and lower light or lower narrow light form or various types of buffer projection (102a) at the bottom ) Is installed to lower the dynamic modulus of elasticity.

Figure 7 (C) is configured as shown in Figure 7 (B) but the heat permeability compared to Figure 7 (B) with a structure in which a buffer member 102 of the flat plate form between the support plate 101 and the buffer projection (102a). This is rather low and structurally more stable.

7D is a structure in which the support plate 101 is formed in the upper part, the buffer protrusion 102a which has a hollow part is provided in the lower part, and the heat insulating material 103 was provided in the lower part.

Such a structure is to reduce the dynamic modulus of elasticity of the entire buffer layer 100, as well as to lower the heat permeability to improve the thermal insulation performance.

7 (E) is configured as shown in FIG. 7 (D), but the structural stability is increased by installing a buffer 102 between the support plate 101 and the buffer projection (102a), due to the buffer 102 The dynamic modulus of elasticity was further improved.

8 (F) is a support plate 101 is installed on the upper portion, the cushioning material 102 is installed on the lower portion of the buffer material 102 itself in the configuration to have a buffer projection (102a) and the hollow portion is simple but dynamic elasticity It is configured to lower the coefficient.

8 (G) is configured as shown in FIG. 8 (F), but the structure of the upper support plate 101 is removed, so that one side of the buffer layer 100 may be recessed with respect to the upper local load, and thus the strength of the buffer layer 100 itself. It is preferable to form with a high material.

8 (H) is configured as shown in FIG. 8 (G), but the heat insulating material 103 is installed in the lower portion has a good elastic modulus and thermal permeability, but as shown in FIG. 8 (G), one side of the upper local load It is preferable that the strength of the buffer layer 100 is high because it has the possibility of sinking.

8 (I) to 8 (L) show a form in which multiple buffer layers 100 are stacked, and the upper hollow portion is not in contact with the lower lightweight foam concrete layer or concrete floor layer by the lower buffer layer 100. It satisfies the thermal insulation performance, and lowers the dynamic elastic modulus by the hollow part, so that the vibration blocking effect is good.

At this time, as shown in Figure 8 (J) to Figure 8 (L) of the upper or lower, each support layer 101 for each buffer layer 100 is configured to prevent the local depression of the buffer layer 100 from the upper load It is preferable.

Obviously, various buffer layers 100 may be applied to the spirit of the present invention in addition to the above-described embodiments, but as described above, the buffer layers 100 satisfying both the vibration blocking performance or the vibration blocking performance and the thermal insulation performance may be applied. It is desirable to.

In the above configuration, the support plate 101 can be formed using one to 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 support plate 101 is preferably formed to a thickness between 0.5 mm to 50 mm.

If it is thinner than 0.5 mm, not only the support function is lowered, but also local deformation occurs, so that the upper lightweight foam concrete layer 20 or the finishing mortar layer 30 cannot be well supported.

In addition, when the thickness is thicker than 50 mm, not only economic efficiency is low, but also there is a problem of narrowing the space for installing a member such as the cushioning material 102.

The support plate 101 should maintain the strength while making the thickness as thin as possible, and should also consider the economics.

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

To this end, a flat plate is formed at the top and the bottom, and the wall portion is formed in the form of a multi-walled form, so that even if a high-strength member using high strength is used, the material can be used with high economical efficiency.

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.

On the other hand, the cushioning material 102 and the heat insulating material 103 is preferably foamed using natural rubber or synthetic rubber as a raw material, or foamed 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 mixed material of these two to six kinds.

In addition, it is also possible to use a mixture of one to eight kinds of foamed grinding materials selected from natural rubber, synthetic rubber, polyurethane, polyolefin, polyethylene, polypropylene, polyvinyl chloride, and ethylene vinyl acetate.

In addition, a polyester nonwoven layer can also be used as the buffer material 102.

In addition, the hollow portion and the buffer protrusion 102a may adjust the diameter, width, thickness, contact area, etc. in consideration of materials, total area, required thickness, and the like of each member.

In the present invention, the waterproof tape 200 is attached to the upper surface of the connection portion of the plurality of buffer layers 100 so as to prevent the water from moving from the top to the buffer layer 100 and the bottom thereof.

The waterproof tape 200 may be used by applying a waterproof tape 200 made of a known water-insoluble material that does not melt by water.

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

On the other hand, in forming the buffer layer connecting structure of the present invention, even in a situation that is not completely waterproof by the waterproof tape 200 of the upper surface, to maintain the waterproofness, is attached to the side of the buffer layer 100, Side waterproof portion 130 having a waterproof material; It is attached to the bottom of the buffer layer 100, the lower waterproof portion 140 having a waterproof material; may be additionally installed.

The side waterproof portion 130 and the lower waterproof portion 140 is composed of any one selected from polyethylene, polypropylene, ethylene vinyl acetate, FBC, foam rubber, foam rubber sheet, a film attached nonwoven fabric It can be simply attached or applied.

As described above, in forming the side waterproof portion 130 and the lower waterproof portion 140, the buffer layer 100 is formed in the form as shown in FIG. 9 in the state where the side waterproof portion 130 and the lower waterproof portion 140 are attached. It is preferable to have the protrusion 110 and the depression 120.

At this time, the side waterproof portion 130 has a higher hardness than the buffer material 102 so that the buffer layer 100 adjacent to each other has a stronger resistance stress when resisting the compressive load by the protrusion 110 and the depression 120 It would be desirable to have.

Referring to the construction method of the connection layer buffer layer 100 for the building floor increased the contact area 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 protrusions 110 and the recesses 120 of each of the buffer layers 100 are assembled so as to fit together, and then the waterproofing tape 200 is attached to the upper portion of the connection portion to fix the buffer layers 100 to each other in a series of connection constructions. This is the finish.

As described above, even if a compressive load is generated at the connection portion to which each buffer layer 100 is connected, the compressive deformation of the boundary portion does not occur.

Therefore, it is easy to attach the waterproof tape 200 to the connection portion, and even after the waterproof tape 200 is attached, the waterproof tape 200 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.
