Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building board that can be affixed to walls and floors to absorb and mitigate external impacts.
[0002]
[Prior art]
Many of the conventional outer walls and partition walls of a building have a structure in which a wall plate is attached to one side or both sides of the frame. The outer wall and the partition wall having such a structure have an advantage that the construction is easy, but there are problems as described below, such as a plywood, an inorganic panel, and a synthetic resin panel as a wall board.
[0003]
[Problems to be solved by the invention]
That is, the plywood, the inorganic panel, the synthetic resin panel and the like used as the wall plate have a problem that they hardly absorb external impacts, and are easily damaged when subjected to external impacts. Moreover, there is a problem that the impact sound is loud, and particularly in the case of a wall having a hollow structure in which wall plates are attached to both sides of the shaft assembly, the impact sound is further increased by resonance.
[0004]
In order to deal with such problems, a shock absorbing sheet or the like is sandwiched between the shaft assembly and the wall plate to alleviate the impact, but the work of sandwiching the shock absorbing sheet or the like at the construction site is cumbersome and causes a decrease in workability. In addition, the buffer sheet may be displaced, peeled off, or dropped out.
[0005]
Similarly, when pasting a floorboard, a buffer sheet or the like may be interposed to reduce the impact, but the workability is reduced because the work of laying the buffer sheet or the like is added before the floorboard is pasted. In addition, the buffer sheet may be misaligned.
[0006]
The present invention has been made to cope with the above-mentioned problems, and the object of the present invention is to absorb and mitigate external impacts simply by attaching them as wall plates or floor plates, thereby preventing damage and reducing impact sound. The object is to provide a building board that can be designed.
[0007]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the building board according to the present invention comprises a synthetic resin warp, weft and a thinner intermediate yarn fused at their intersections, and the intermediate yarn within a square mesh formed by the warp and weft. A synthetic resin net provided with a superposition of the warp, weft and intermediate yarn on the back of the substrate so that the warp, weft and intermediate yarn are all close to the back of the substrate, and adhesive is applied in the square mesh so as to cover the intermediate yarn. to fill in, warp, the adhesive between the back surface of the weft and the intermediate thread and the substrate by interposing a thin layer, is characterized in that the synthetic resin net and the substrate was bonded and integrated.
[0008]
When a building board with such a structure is attached as a wall board or floor board, when an impact force is applied from the outside, a relatively flexible synthetic resin net on the back of the board exerts a buffering action to absorb and mitigate the impact force. can do. Therefore, damage to the substrate can be prevented, and impact noise can be suppressed. Moreover, since the synthetic resin net is bonded and integrated with the substrate, the troublesome work of sandwiching the synthetic resin net at the construction site is unnecessary, and good workability can be maintained. In particular, the building board of the present invention is a net having a thin intermediate thread in a square mesh in which a synthetic resin net is formed of warp and weft, and an adhesive is filled in the square mesh so as to cover the intermediate thread. Since the synthetic resin net and the substrate are bonded and integrated, the adhesive strength of the synthetic resin net to the substrate is extremely high. Therefore, there is no possibility that the synthetic resin net peels off from the substrate, and a good buffering action can be continuously exhibited over a long period of time.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
[0010]
1 is a partial rear view of a building board according to an embodiment of the present invention, FIG. 2 is an enlarged partial sectional view taken along line AA of FIG. 1, and FIG. 3A is a synthetic resin net used for the building board. 3B is a partial cross-sectional view taken along the line BB of FIG. 3A, FIG. 4 is a partial cross-sectional view showing an example of use of the building board, and FIG. It is a fragmentary sectional view showing an example of use.
As shown in FIGS. 1 and 2, the building board P is obtained by superposing a synthetic resin net 2 on the back surface of a building substrate 1 and bonding and integrating them with an adhesive 3.
[0011]
The board | substrate 1 can use all if it is the board | plate material for construction conventionally used widely as a wall board or a floor board, for example, a plywood for construction, an inorganic board, a resin board etc. are used suitably.
[0012]
As shown in FIGS. 3A and 3B, the synthetic resin net 2 is obtained by fusing a thick warp 2a, a weft 2b, and a thinner intermediate yarn 2d of the synthetic resin at respective intersections to thereby obtain a thick warp 2a. And a net having a thin intermediate thread inside a square mesh 2c formed by the weft 2b. In the net 2 shown in FIG. 3 (a), the intermediate yarn 2d is provided in the vertical direction inside the rectangular mesh 2c, but may be provided in the horizontal direction, or two in the vertical and horizontal directions. It may be done.
[0013]
As shown in FIGS. 1 and 2, the synthetic resin net 2 is superposed on the back surface of the substrate 1 so that the warp yarn 2a, the weft yarn 2b, and the intermediate yarn 2d are all close to the back surface of the substrate 1, and the thin intermediate yarn 2d The substrate 1 is bonded and integrated with an adhesive 3 filled in the rectangular mesh 2c so as to cover the substrate. Therefore, the adhesive strength of the synthetic resin net 2 to the substrate 1 is extremely high, and there is no possibility that the synthetic resin net 2 is peeled off from the substrate 1 and dropped off. Although not shown in FIG. 2, the adhesive is interposed in a thin layer between the yarns 2 a, 2 b, 2 d of the synthetic resin net 2 and the back surface of the substrate 1. Thus, the yarns 2a, 2b, and 2d are directly bonded to the back surface of the substrate 1.
[0014]
For example, as shown in FIG. 4, the building board P as described above has a synthetic resin net of the building board P on one side (for example, the outdoor side) of the shaft assembly 4 constituted by the pillars 4 a and the trunks 4 b. Attached and fixed with a fastener or the like (not shown) so that 2 is inside. And the wall plate 5 for normal interior is stuck and fixed to the opposite surface side (for example, indoor side) of the shaft assembly 4, and the wall of a hollow structure is formed. In addition, in the wall of FIG. 4, although H steel is used as the pillar 4a, of course, you may use a prism other than this, and it replaces with the wall board 5, and is the board P for construction of this invention. Of course, it may be fixed to the opposite surface side of the shaft assembly 4.
[0015]
Thus, when the building board P of the present invention is stuck and fixed to one side of the shaft assembly 4, when an impact force is applied to the board 1 of the building board P from the outside, a relatively flexible synthetic resin net 2 on the back surface of the board. Can absorb and relieve the impact force. Therefore, it becomes difficult for the board | substrate 1 to be damaged, and an impact sound can also be reduced significantly. Moreover, since the synthetic resin net 2 is firmly bonded and integrated on the back surface of the substrate 1 as described above, there is no possibility of peeling or dropping from the substrate 1, and a good buffering effect is maintained over a long period of time. Can be demonstrated. In addition, when the building board P of the present invention is used, since there is no need for the troublesome work of sandwiching a buffer sheet or the like between the frame assembly 4 and the wall board at the construction site as in the past, the workability is also good. is there.
[0016]
If the hollow portion of the shaft assembly 4 is filled with a sound-absorbing filler (for example, a waste material fragmented from a construction site is solidified with a binder), the impact sound can be further reduced. Moreover, if a heat insulating material such as a resin foam is filled, the heat insulating property of the wall can be improved.
[0017]
FIG. 6 is a partial cross-sectional view showing another example of use of the building board P of the present invention. The building board P of the present invention is synthesized as a floor board on the surface of a concrete floor 6 in an apartment house or the like. The resin net 2 is laid on the lower side.
[0018]
As described above, when the building board P of the present invention is laid as a floor board, even if children jump, the impact is absorbed and alleviated by the synthetic resin net 2 on the back surface of the board of the building board P. It becomes difficult to convey. Moreover, since no work for laying a buffer sheet or the like is required at the time of construction, the workability is also good.
[0019]
【The invention's effect】
As is clear from the above description, the building board of the present invention can absorb and mitigate external impacts with the synthetic resin net on the back side of the substrate, thereby preventing damage to the substrate and reducing impact sound. There is an effect that can be done. In addition, since the synthetic resin net does not peel or drop off, it can continue to exhibit a good buffering action over a long period of time, and there is no need to sandwich or lay buffer sheets at the construction site. Therefore, there is a remarkable effect that the workability is also good.
