Description

  The present invention relates to a house reinforcing kit and a method of using the same for the purpose of improving the workability of the reinforcement work of a house when the house is renovated.

  In general, in addition to prefabricated houses produced by factories, the length and width of each member, for example, columns, horizontal members, beams, foundations, etc. are standardized in ordinary houses and apartment houses made of wooden buildings. Processing is also performed at the factory, and processing of joint portions of each member is also performed at the factory, and the number of processes at the site is reduced and assembly work is often simplified.

  Moreover, as a seismic policy of a house, a reinforcing member such as a bearing wall or a brace is attached between adjacent columns so that the house has sufficient seismic strength (for example, see Patent Document 1).

  However, in order to reinforce the earthquake resistance of the house, it was necessary to peel off the ceiling and floor at the site and install braces. Therefore, there is a problem that the construction is troublesome and the construction period and cost of the construction work increase. In addition, a skilled construction engineer is required to install a brace that supports the beam in the ceiling for reinforcing the column.

  Therefore, in the frame structure of a house, an outdoor column is provided outdoors along the outer wall relative to the position of the indoor column already installed indoors, and the outdoor column and the indoor column are fastened with a fastener and reinforced. It has been proposed to reinforce the joint of the indoor pillar and the beam overlaid on the indoor pillar with a reinforcing material (see, for example, Patent Document 2).

However, in the case of such a framework, since it is supported by a single long plate, for example, when a crack or the like occurs in one place in the plate due to an earthquake or the like, the breakage proceeds from the crack, and the effect is There was a problem that the seismic strength was lowered.

  Therefore, the present invention has been made in view of the above-described circumstances, and its purpose is to make it easier to reinforce a house at the time of home renovation, to improve workability and to make it more earthquake resistant. An object of the present invention is to provide a house reinforcing kit excellent in strength and a method of using the kit.

  The above object of the present invention is to provide a plurality of horizontal rails connecting between a pair of columns extending from a base under the floor to a beam in the ceiling, a stopper for fixing the horizontal rails to the pair of columns, and the horizontal rails. And a reinforcing plate attached to an opening formed by the pair of pillars, and the reinforcing plate is used to reinforce the earthquake-resistant structure of the house. The

  Moreover, the said objective of this invention is effectively achieved by providing the kit for a house reinforcement characterized by providing the said crosspiece 3 or more between a pair of adjacent pillars.

  Moreover, the said objective of this invention is achieved more effectively by providing the kit for house reinforcement characterized by the said reinforcement board being a MDF board.

Furthermore, the above-mentioned object of the present invention is a method for strengthening the earthquake-resistant structure of a house with a reinforcing member between a pair of columns extending from a base under the floor to a beam in the ceiling,
A step of fixing a plurality of horizontal beams extending in the horizontal direction between the pair of columns; a step of fixing the horizontal beam to the columns by a stopper at an intersection of the horizontal beam and the columns; And a step of arranging a reinforcing plate side by side in an opening formed by the pair of columns and fixing the reinforcing plate to the pair of columns and the horizontal rail around the reinforcing plate. This is accomplished more effectively by providing a method of using the kit.

  As described in detail above, according to the house reinforcing kit and the method of using the same according to the present invention, when renovating the house, it is not necessary to carry out a large-scale construction, and it can be constructed indoors with a simple method and in a short construction period. Can be done at low cost. In addition, since a horizontal beam is attached between adjacent columns and a reinforcing plate is fixed to the column and the horizontal beam, the seismic strength is further increased.

  Further, by dividing the reinforcing plate into a plurality of sheets, the force applied to the plate during an earthquake or the like is dispersed, so that the earthquake resistance performance is improved. Furthermore, since the MDF board can be attached by a simple method, there is no variation in the finish by the construction engineer, and the finish as designed can be easily obtained.

  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a schematic front view of a house showing a state where the house reinforcing kit according to the first embodiment of the present invention is used, and FIG. 2 is a schematic side view of the house of FIG. A general wooden house has a basic unit of 3 scales, that is, 910 mm. Therefore, in this embodiment, the three scales will be described as a basic unit, but the present invention is not limited to this.

  As shown in FIG. 1, a pair of adjacent pillars 1 and 1 extend in a vertical direction (up and down direction in FIG. 1) from a base 2 under the floor of a wooden house to a beam 3 in the ceiling, and in a horizontal direction (FIG. 1). They are connected by four horizontal bars 4 extending in parallel in the left-right direction). Moreover, the crosspiece 4 is fixed to the pillar 1 by a stopper 5 as shown in FIG. 3 at the intersection with the pillar 1, and this stopper 5 includes an L-shaped flange portion 5a and this flange portion. And a support bar 5b of 5a.

  In addition, three reinforcing plates 6a, 6b, 6c are arranged in the vertical direction in three openings formed by a pair of adjacent pillars 1, 1 and four horizontal rails 4, respectively. Around 6a, 6b, 6c, it is fixed to the pillar 1 and the crosspiece 4 with nails or wood screws.

  In addition, the pillar 1 extending from the base 2 under the floor is fixed at the lower end to the base 2 by a hole-down hardware 7, and usually, the upper end is fixed to the beam 3 in the ceiling by a battledore bolt 8 or the like.

  In addition, the code | symbol 9 in FIG. 1 is the foundation concrete located under the said base 2. As shown in FIG.

  As described above, the pair of adjacent pillars 1 and 1 are connected by the four horizontal rails 4 and firmly fixed by the stopper 5, so that the pillar 1 can be vertically and horizontally oriented. The acting force can be supported by a frame structure formed by a plurality of horizontal rails 4. Further, the three openings formed by the pair of columns 1 and 1 and the horizontal beam 4 are closed by the reinforcing plates 6a, 6b, and 6c, and the column 1 and the horizontal beam are formed around the reinforcing plates 6a, 6b, and 6c. 4 is fixed with a nail or a wood screw or the like, the force acting on the column 1 from the vertical direction or the horizontal direction can be supported by the wall structure of the reinforcing plates 6a, 6b, 6c. Therefore, the effect of further increasing the earthquake resistance of the house can be obtained.

  In this embodiment, an MDF board (Medium Density Fiberboard) is used for each of the reinforcing plates 6a, 6b, 6c. Regarding the dimensions of the reinforcing plates 6a, 6b, and 6c, the reinforcing plates 6a and 6c have a thickness of about 9 mm, a horizontal length of 910 mm, and a vertical length of 1000 mm. The reinforcing plate 6b Although the vertical length of 330 mm is used, the reinforcing plates 6a, 6b, 6c are not limited to this. Thus, by dividing the reinforcing plate into three pieces 6a, 6b and 6c, the force acting on the reinforcing plates 6a, 6b and 6c is dispersed. That is, for example, when a crack occurs only in the reinforcing plate 6a where the force is most applied at the time of an earthquake and no cracks occur in the remaining reinforcing plates 6b and 6c, Because it can withstand loads such as aftershocks, seismic performance is improved.

  Further, by dividing the reinforcing plate into three pieces 6a, 6b, and 6c, for example, when installing the reinforcing plates 6a, 6b, and 6c in the construction work, a nail or a wooden screw or the like is mistakenly applied to the MDF. When a crack occurs in the board 6b, it is sufficient to replace only the MDF board 6b in which the crack has occurred, so that the workability and maintainability are also improved.

  Further, the use of the MDF board for the reinforcing plates 6a, 6b, 6c also has an effect of being excellent in sound absorption and heat insulation.

  Further, according to the present embodiment, the reinforcing plates 6a, 6b, 6c are fixed to the opening formed by connecting the cross rail 4 between a pair of adjacent columns 1 and 1, and each reinforcing plate 6a. , 6b, and 6c, a nail or a wood screw or the like is driven and fixed to the pillar 1 and the crosspiece 4. Therefore, it is possible to perform the reinforcement work by a simple method, and it is possible to obtain the effect that even if it is not a skilled construction engineer, it can be finished as designed without failing.

  In addition, although the present Example demonstrated the case where the reinforcement boards 6a, 6b, and 6c were MDF boards, this invention is not restricted to such an MDF board, For example, a particle board, a normal plywood, a flame-resistant plywood, a hard fiber board ( The present invention can also be applied using a known reinforcing plate such as a hard board) or a soft fiber board (insulation board), and the same actions and effects as those in the above embodiment can be achieved.

  The stopper 5 is generally made of a metal such as iron, but may be a stopper made of other materials as long as it has the same strength. Further, it is needless to say that a stopper that exhibits the same effect as in the present embodiment can be applied even if the shape is different.

  Furthermore, if the cross rail 4 is provided between the adjacent pillars 1 and 1, it is only necessary to peel off the interior decorative board between the floor and the ceiling during construction work. Is also possible. Therefore, the conventional large-scale construction is not required, the construction period is shortened, and the reinforcement construction can be performed at a low cost.

  In addition, for example, the number of the cross rails 4 and the reinforcing plates, or the thickness of the reinforcing plates may be slightly increased or decreased, such as five horizontal rails 4 and four reinforcing plates. An effect can be obtained. Further, as in this embodiment, a combination of reinforcing plates having different areas may be used, or reinforcing plates having the same area may be used.

  FIG. 4 is a schematic front view of a wooden house showing a method of attaching the reinforcing plates 6a, 6b and 6c in the case of the second embodiment of the present invention, that is, in the case of 1820 mm. In addition, when attaching the reinforcing plates 6a, 6b, and 6c, other configurations are substantially the same except that the pillar 1 is shared. For this reason, in FIG. 4, the same reference numerals are given to the components corresponding to the first embodiment.

  The second embodiment has a wall area twice as large as that of the first embodiment and is supported by a frame structure including three columns including the common column 1. Therefore, the earthquake resistance strength of the house is further improved.

  FIG. 5 is a schematic side view of a wooden house showing a mounting state of the reinforcing plates 6a, 6b, 6c in the case of a Japanese-style room that allows the real wall, that is, the pillar 1 to be seen, as a third embodiment of the present invention. In the present embodiment, the horizontal rail 4 is made thinner by the thickness of the reinforcing plates 6a, 6b, 6c, and other configurations are provided except that the reinforcing plates 6a, 6b, 6c are fixed inside the pillars. Are substantially identical. For this reason, in FIG. 5, the same reference numerals are given to the components corresponding to the first embodiment.

  That is, in the third embodiment, the house reinforcing kit can be used for any house structure by changing the design as appropriate regardless of the kind of house.

  Incidentally, in each of the above embodiments, a house, that is, a Japanese house that is a wooden house has been described as an example. However, the present invention is not limited to a Japanese house, and the length of the horizontal beam, the area of the reinforcing plate, and the horizontal beam or the reinforcing plate It can also be applied to imported houses by changing the materials and the like as appropriate.
