The present invention relates to a structure for reducing heavy floor impact sound in buildings, and more particularly, to a structure for reducing heavy floor impact sound generated in a slab (floor plate) in a wall-slab building.

In general, when constructing buildings such as buildings, apartments, houses, etc., the interior space is secured on each floor by forming slabs (floors) and walls of a certain thickness using mainly concrete.

In this construction, the shock generated from the upper floor of the building, that is, the slab, is inevitably transmitted to the lower floor by vibration, and the noise generated by the vibration (heavy floor impact sound) greatly inconveniences the residents of the lower floor. It is true.

Therefore, in an effort to prevent this, a soundproofing panel and a sound absorbing plate are laid on the upper surface of the slab, or FRP is padded on the bottom of the slab to prevent the vibration of the slab from being transferred to the lower floor through the wall. However, until now, almost all studies to prevent heavy floor impact sound have been concentrated on the slab.

However, the present inventors have tried various experiments for minimizing the vibration of the slab such as increasing the thickness of the slab in order to reduce the heavy floor impact sound for many years or closely contacting the steel beam, steel plate, carbon plate, etc. on the bottom of the slab, In the case of the ramen-supported building that supports the slab, when the above methods are taken, the pillar absorbs vibration and has a significant effect of reducing the impact on the heavy floor. However, the wall structures, that is, the wall slab-type buildings, have the following methods. Could not get any effect.

In the case of wall structure, it is judged that the vibration of the slab is transmitted to the wall as it is because of the structural feature that the slab and the wall structure are integrally connected.

Eventually, in the case of wall-structured building, it was found that even though various methods for preventing vibrations were applied to the slab, it was impossible to block the vibration of the heavy floor impact sound of the wall, and the heavy floor impact sound could not be weakened. It was concluded that no mitigation effect could be obtained.

In addition, adding a reinforcement plate to the bottom of a conventional slab requires that bracket members for preventing the fall of the reinforcement plate should be formed on both sides of the reinforcement plate, such as an increase in installation and cost, and a narrow space due to the protrusion of the bracket and the reinforcement plate. Since there are various problems, the necessity of a new structure to solve this problem is more necessary than ever.

Therefore, the present inventors consider that in the case of a wall structure building, it is inefficient to devise anti-vibration means and methods on the slab itself, so that at least one reinforcing plate capable of reinforcing the tensile force is adhered or attached to the wall surface. Increasing the cross-sectional area of the wall and at the same time strengthening the stiffness of the wall significantly reduces the vibration transmitted from the slab to the wall, thereby reducing the weight floor impact sound.

In addition, the present invention is to minimize the shaking of the wall by contacting the upper end of the reinforcing plate to the upper slab, the lower end of the lower slab.

When described in more detail by the accompanying drawings, the configuration of the present invention for achieving the above object as follows.

1 to 5, in the structure for reducing the weight floor impact sound of the wall structure building, as shown in Figures 1 to 5 to be able to reinforce the tensile force of the wall on the surface (11) surface 11 of the wall structure building Reinforcing plate 100 is configured to be bonded or attached to at least one or more.

In addition, the present invention may be configured such that the whole or part of the reinforcing plate 100 is buried in the wall 10 of the wall structure building as shown in FIG.

At this time, the upper end of the reinforcing plate 100 is in contact with the upper slab 20, the lower end is in contact with the lower slab (30).

The material of the reinforcing plate 100 should be a material having a stronger tensile force than the concrete material, which is a configuration necessary to give a strong tensile force on the wall, and increase the cross-sectional strength.

Various materials may be used as the material of the reinforcing plate 100, but as a result of the experiment, the carbon plate, the steel sheet, the FRP plate, etc., in which the carbon fiber sheet and the sheet of carbon fiber sheet are overlapped with each other, have a price-performance ratio. Excellent and most preferred.

In this case, the reinforcement plate 100 may be bonded or attached to cover the entire area of the surface 11 of the wall 10, or may be attached or attached to cover only a partial area.

In this case, in the case of the reinforcement plate 100 which can cover only a part of the wall area, it is preferable that the reinforcing plate 100 is formed at the center of the wall surface when only one is bonded or attached, and in two cases, as shown in FIG. 1 or 2. It is preferable to form at regular intervals on both sides of the wall so as to be slightly spaced apart from.

Of course, the reinforcement plate 100 which can cover only a part of the wall area may have a better effect as the number is larger, but it may be desirable to adjust the most suitable number in consideration of economics.

In addition, the reinforcement plate 100 is formed on both sides of the wall has a much better vibration reduction effect than that formed only on the wall of one side.

In addition, the reinforcing plate 100 is the upper end to the upper slab 20, the lower end is in contact with the lower slab 30 is the reason why the reinforcement plate 100 is between the upper slab 20 and the lower slab 30 It is because the vibration of the wall 10 can be reduced more effectively by making it fit.

Thus, the role of the reinforcing plate 100 in the present invention is to be in close contact with the surface of the wall 10 to increase the cross-sectional area, thereby increasing the cross-sectional strength and tensile force on the wall will have the effect of holding the wall shaking in the end. .

In the present invention, the method of adhering or attaching is changed by the material of the reinforcing plate 100, and the area of adhering or attaching is also different.

That is, since the carbon fiber sheet is only about 0.165 mm thick, the carbon fiber sheet should be directly adhered to the wall surface, and preferably bonded to the entire area of the wall surface.

However, the carbon plate, steel plate, FRP plate, etc. have a considerable thickness of about 10 to 20 mm, and the rigidity is also a very good material, so it is economical to adhere to a partial area of the wall surface.

At this time, the carbon plate, steel plate, FRP may be attached or adhered to the wall surface through a rubber or synthetic resin, or the like, or may be installed to be buried in whole or in part inside the wall.

In order to adhere the reinforcing plate 100 to the wall surface, a building adhesive generally used is used, and for attachment, a bolt for concrete may be used. Even when buried, it is fixed to the wall by the adhesion means or the attachment means.

In addition, considering the economical aspect, the present invention reinforcement plate 100 is preferably installed only in the concrete bearing wall, and when installed in a conventionally built building will be installed in a protruding type on the wall, the new building in advance of the wall It may be configured to be installed by forming a reinforcing plate insertion groove on the surface.

As described above, the present invention provides a cross section strength and tensile force to the wall by installing a reinforcement plate on the surface of the wall, unlike the conventional floor slab reduction means installed in the slab, thereby reducing the vibration of the wall, thereby minimizing the weight floor impact sound. It has the effect of creating a living environment.

In addition, the present invention is a simple structure for adhering or attaching the reinforcing plate to the wall surface, so that it is easy to install, can utilize a wider indoor space, and economical construction is a very useful invention.
