  In various buildings, siding boards are sometimes used as outer wall materials for the purpose of improving the efficiency of construction work and improving the appearance. When a balcony or a fence is installed in such a building, its arms are inevitably arranged so as to penetrate the inside and outside of the siding board. Therefore, cutouts are formed on the siding board according to the arrangement of the arms, but there is a limit to the accuracy of the siding board installation, and there is a margin in the size of the cutout so that it does not increase labor during construction. Many.

  If there is a margin in the siding board cutout, the gap between the arms will be filled with sealing material to prevent rainwater from entering. However, the sealing material may deteriorate over time, and the installation of a balcony or the like will cover the sealing material and make maintenance and inspection difficult. As a result, rainwater infiltrates into the building, and the skeletal material may deteriorate without being recognized by residents. In addition, since a plurality of parts are arranged around the cutout, drainage tends to be poor, and water droplets remain moistened, which may have an adverse effect on arms and the like.

  The present invention was developed on the basis of such a situation, and in a building using a siding board as an outer wall material, it prevents the intrusion of rainwater into the interior, and also has a support structure such as a balcony or a fence that is excellent in drainage. The purpose is to provide.

  The invention according to claim 1 for solving the above-mentioned problem is a support structure for installing a balcony, a fence or the like on the outside of a siding board, and a skeletal material such as a beam is arranged inside the siding board. And a balcony, a basket and the like are held in aerial with arms extending substantially horizontally, a connector for fixing the arms to the skeleton, a contact plate capable of contacting the inner surface of the siding board, and the contact An elastic body that presses the plate, and the connector is disposed on the tip of the penetrating body, a contact plate that contacts the surface of the skeleton, a penetrating body that penetrates the inside and outside of the siding board, and An upright plate inserted into a slit formed at the end of the arm, and the abutment plate and the frame material are integrated with a long bolt or the like, and the upright plate and the arm are integrated with a pin or the like, and the siding Board before A cutout is provided through which a penetrating body can be inserted with a margin, the contact plate is provided with a window hole through which the penetrating body can be inserted without a gap, and the contact plate is disposed so as to be displaceable along the penetrating body. The elastic body is a support structure that is arranged between the contact plate and the contact plate, and closes the cutout by pressing the contact plate against the siding board.

  The present invention provides a support structure for installing an external structure such as a balcony or a fence in a building that uses a siding board as an outer wall material, and attaches a brace that holds the external structure in an imaginary manner to the skeleton of the building Is for. The siding board is a plate-like outer wall material made of cement, metal, wood, etc., and it is commercialized at the factory, and the outer wall is completed by laying down the side of the building without any gaps. Therefore, the construction work can be rationalized, and the appearance and water resistance are excellent.

  The skeletal material refers to a beam, a pillar, or the like that constitutes the skeleton of a building, and is disposed inside the siding board. The arm is a rod-like timber that holds a balcony or the like in an aerial manner, and extends almost horizontally. One end of the arm is supported by a skeletal material, and the other end is inserted into the floor of the balcony or the inside of a fence. However, in the present invention, the arms are not arranged so as to penetrate the inside and outside of the siding board, but the whole is arranged outside the siding board. The arms are not used alone, but a plurality of arms are arranged along the horizontal direction to receive the load acting on the external structure.

  The connector is a group of parts for fixing the braces to the skeleton material, and is assumed to have a contact plate, a penetrating body, and an upright plate, but these specific shapes are free. The abutting plate is a portion that contacts the surface of the skeleton material in order to stably place the connector, and the abutting plate is fixed to the skeleton material using bolts, nails or the like. The penetrating body is a portion that extends perpendicularly from the abutment plate, penetrates the inside and outside of the siding board, and projects to the outside of the building. The form of the penetrating body can be freely selected such as a rod shape or a plate shape.

  The upright plate has the role of integrating the connector and arm, and is a plate that is placed at the end of the penetrating body and outside the siding board, and is inserted into a slit machined at the end of the arm and withstands vertical loads. Literally arranged vertically. Moreover, the slit which accommodates an upright board is processed so that the upper and lower surfaces of an arm end part may be tied. In addition, if the penetration body of a connector is made into plate shape, a penetration body and an upright board can also be integrated into one component. In addition, upright plates and slits should be arranged in two rows in parallel for strength, but they can also be arranged in one row.

  The contact plate is a plate that is disposed so as to be displaceable with the penetrating body as a guide and that can contact the inner surface of the siding board. Therefore, a window hole for inserting the penetrating body is formed in the contact plate. The window hole prevents the intrusion of rainwater by making the gap with the penetrating body as small as possible within a range that does not hinder the displacement of the contact plate.

  The elastic body, such as a coil spring, generates a reaction force by being compressed in the axial direction, and is disposed between the contact plate and the contact plate and has a role of forcibly pressing the contact plate against the siding board. In order to prevent the dropout, the elastic body is held by a penetrating body or a bolt. The elastic body is an important part for securing the sealing property, and it is preferable to use a plurality of elastic members for one connecting tool.

  A cutout is formed in the siding board to allow the penetrating body to pass therethrough. The size of the cutout shall be large enough for the penetrating body in consideration of the installation error of the siding board. Therefore, a gap is generated between the cutout and the penetrating body, but the intrusion of rainwater into the inside is prevented by closing the gap with a contact plate behind it. Therefore, the contact plate is sized so as to completely close the cutout of the siding board.

  The specific shape of the connector is flexible as described above, and it is possible to bend a single steel plate and integrate from the contact plate to the upright plate, but separately manufacture the penetrator and the upright plate. They can be integrated with bolts. In addition, the cutouts formed on the siding board and the window holes formed on the adhesion plate are determined according to the shape of the penetrating body. If the penetrating body is a round bar, these are also circular, and the penetrating body is plate-shaped. If present, these are elongated rectangles.

  In this way, by placing the contact plate and elastic body inside the siding board and pressing the contact plate against the inner surface of the siding board, it is possible to prevent rainwater from entering the interior without performing work such as sealing. it can. Further, even when the distance between the skeleton material and the siding board is different by using the contact plate and the elastic body, the function can be exhibited without any problem, and the same-shaped connector can be used in various situations. Furthermore, since the arm is integrated with the connector via the upright plate, the entire arm is disposed outside the siding board, and it is easy to provide a gap between the siding board and the arm, and it is possible to prevent water droplets from remaining.

  As in the invention described in claim 1, as a support structure of an arm tree for holding an external structure such as a balcony in an imaginary manner, a connecting tool having a penetrating body, an adhesive plate displaceable along the penetrating body, and an adhesive plate By using an elastic body that presses against the siding board, the entire arm can be placed outside the siding board, and the cutout formed on the siding board can be completely covered with a close-up board, such as rainwater inside the building. Intrusion can be prevented. This eliminates the need for water measures such as the application of a sealing material at the time of construction, simplifies the work, eliminates the need for considering deterioration of the sealing material, and facilitates maintenance management after construction.

  In addition, since the contact plate is pressed by an elastic body, even if the distance between the skeleton material and the siding board is different, the original function is exerted without difficulty, and the connector having the same shape can be used universally in various situations. Furthermore, by fixing the arm using an upright plate protruding outside the siding board, a certain gap can be secured between the siding board and the arm. Therefore, the drainage is good, and even when water droplets adhere to the arm and the like, it does not remain for a long time and can prevent corrosion of the arm and the like.

  FIG. 1 is a specific example of a support structure according to the present invention, in which a skeleton material 51 and a brace 61 that are opposed to each other with a siding board 41 interposed therebetween are integrated by a connector 11. The siding board 41 covers the entire side surface of the building, but only a small part is drawn in this figure. The skeleton material 51 is a beam extending in the horizontal direction and constitutes the skeleton of the building. The arm 61 is a bar material that supports a balcony, a basket, or the like, and is arranged so as to protrude from the siding board 41. The arm 61 is fixed by the connector 11, and the whole is arranged outside the siding board 41.

  The connector 11 includes a contact plate 12 disposed inside the siding board 41, a penetrating body 14 extending from the contact plate 12, and a metal fitting 21 inserted into the arm 61, of which the contact plate 12 is The metal plate cut into a rectangular shape is in contact with the side surface of the skeleton material 51. Moreover, two penetration bodies 14 are arrange | positioned up and down with a column-shaped metal rod. A protrusion 15 having a narrowed cross section is formed at one end of the penetrating body 14, and the protrusion 15 penetrates the contact plate 12. On the other hand, the other end of the penetrating body 14 is hollowed out to form a hollow hole 19 having a circular cross section.

  In order to insert the protrusion 15 that protrudes from the contact plate 12, a round groove 54 is processed on the side surface of the skeleton material 51. The round groove 54 has a size that allows the protrusion 15 to be fitted without a gap, and restricts the displacement of the connector 11. Further, the connector 11 is integrated with the skeleton material 51 via the long bolt 59. Therefore, an inner hole 53 into which the shaft portion of the long bolt 59 is inserted is processed at the back of the round groove 54, and a counterbore 52 that accommodates the head of the long bolt 59 is processed at the tip. In order to prevent deformation of the counterbore 52, a washer 58 is incorporated in the head of the long bolt 59.

  The penetrating body 14 protrudes outside through the cutout 43 of the siding board 41. And the metal fitting 21 is inserted in the front-end | tip of the penetration body 14 protruded outside. The metal fitting 21 bears the connection between the coupling tool 11 and the arm 61, and is formed by forming a metal plate into a U shape. The front plate 22 located at the center and the two upright plates 23 projecting from the side ends thereof. The front plate 22 is formed with two round ridges 24 arranged vertically. The round tenon 24 is formed by extruding the front plate 22 and is adjusted in position and size so that it fits into the tenon hole 19 of the penetrating body 14 without a gap. The metal fitting 21 is integrated with the penetrating body 14 via a short bolt 29.

  Two rows of slits 63 are processed at the end of the brace 61 in order to insert the upright plate 23 of the metal fitting 21. Further, on the end face of the arm 61, a step 62 is processed between the two rows of slits 63 in order to accommodate the front plate 22 of the metal fitting 21. And after inserting the upright board 23 in the slit 63, the pin 69 is driven in from the side surface of the arm 61, and both are integrated. In order to allow the pins 69 to pass, the upright plate 23 is provided with two sets of upper and lower pin holes 26 and a pin groove 25 thereon, and further, on the side of the arm 61, the pin hole 26 and the pin groove 25 are concentric. The horizontal hole 65 is processed at the position. The lateral hole 65 crosses the two rows of slits 63 and reaches the opposite surface.

  The contact plate 46 is disposed between the contact plate 12 and the siding board 41, and is disposed so as to be displaceable using the penetrating body 14 as a guide. Therefore, the contact plate 46 is provided with a window hole 47 having the same diameter as that of the penetrating body 14, and prevents the intrusion of rainwater from the window hole 47 while allowing the contact plate 46 to be displaced. Further, an elastic body 17 using a coil spring is disposed between the contact plate 12 and the contact plate 46. The elastic body 17 is incorporated in the penetrating body 14 in order to prevent dropping, and the natural length is adjusted so as to press the contact plate 46 against the siding board 41.

  A cutout 43 is formed in the siding board 41 in order to insert the penetrating body 14. The cutout 43 is formed before being spread on the side surface of the building in order to simplify the construction work, but the penetrating body 14 is given a margin in size in consideration of installation errors and the like. Therefore, the contact plate 46 is sized so as to cover the entire region of the cutout 43 without difficulty. The cutout 43 in this figure is circular in two places at the top and bottom, but can be replaced with an oval shape with the top and bottom connected.

  FIG. 2 shows a state in which the support structure of FIG. 1 is viewed from the inside of the building. The frame material 51 and the penetrating body 14 are attracted by a long bolt 59, and a female screw 18 is formed at the center of the penetrating body 14 so that the long bolt 59 can be screwed together. Further, in order to insert the long bolt 59, a counterbore 52 and an inner hole 53 are processed in the frame material 51, and a washer 58 is incorporated in order to prevent the long bolt 59 from being depressed.

  A protrusion 15 with a reduced diameter is provided on one end side of the penetrating body 14, which passes through the receiving hole 16 of the contact plate 12 and fits into the circular groove 54 of the skeleton material 51. The contact plate 12 and the penetrating body 14 may be integrated by welding or adhesion. When the long bolt 59 is screwed into the female screw 18 and tightened, the two are attracted and the contact plate 12 is in close contact with the frame material 51.

  The metal fitting 21 arranged on the outside of the siding board 41 has a U-shape composed of a front plate 22 and an upright plate 23, and a round boss 24 is formed on the front plate 22. By fitting the round tenon 24 into the tenon hole 19 of the penetrating body 14, the displacement of the metal fitting 21 is restricted, and a short bolt 29 is inserted between the two upright plates 23, and the tip of the short bolt 29 is inserted into the female screw 18 of the penetrating body 14. The metal fitting 21 is fixed to the penetrating body 14 when screwed into the through body 14. In addition, in order to insert the shaft portion of the short bolt 29, a round hole 28 is provided at the center of the round boss 24, and the head of the short bolt 29 is accommodated inside the round boss 24.

  FIG. 3 shows a step in the middle of assembling the elements shown in FIG. After the contact plate 12 and the penetrating body 14 are integrated, when the contact plate 12 is brought into contact with the side surface of the skeleton material 51 and the long bolt 59 is inserted from the back surface of the skeleton material 51, the long bolt 59 and the penetrating body 14 attract each other. The contact plate 12 is in close contact with the skeleton material 51. Next, the elastic body 17 is disposed around the penetrating body 14, and the contact plate 46 is further incorporated into the penetrating body 14. The window hole 47 of the contact plate 46 is formed so as to be slidable with respect to the penetrating body 14 and does not restrict the displacement of the contact plate 46 while ensuring sealing. When the elastic body 17 is in a natural state, the contact plate 46 is pushed near the tip of the penetrating body 14.

  FIG. 4 shows a state in which siding boards 41 are spread after FIG. When the siding board 41 is laid down, due to the arrangement of the skeleton material 51 and the siding board 41, the contact plate 46 is pushed into the skeleton material 51 side, and the elastic body 17 is compressed. As a result, the contact plate 46 is in close contact with the inner surface of the siding board 41. Since the contact plate 46 is larger than the cutout 43 of the siding board 41, the gap between the outer edges of the penetrating body 14 is completely closed to ensure sealing.

  The penetrating body 14 protrudes outside the siding board 41 through the cutout 43, and the metal fitting 21 is attached to the tip thereof. As a result, the metal fitting 21 does not come into contact with the siding board 41, and rainwater quickly falls without being affected by surface tension or the like. Further, the siding board 41 is not pressed by a load of a balcony or the like, and deformation or cracking of the siding board 41 can be prevented.

  FIG. 5 shows the final stage in which the elements of FIG. 1 are assembled. The upright plate 23 of the bracket 21 is inserted into the slit 63 of the arm 61, and a pin 69 is driven from the side surface of the arm 61, so that the bracket 21 and the arm 61 are integrated. As a result, the arm 61 is supported by the skeleton material 51 via the connector 11, and the entire arm 61 is disposed outside the siding board 41, and a gap is secured between the side surface of the siding board 41 and the end surface of the arm 61. . The elastic body 17 is compressed, and the contact plate 46 is in close contact with the siding board 41 by the reaction force. The protrusion 15 of the penetrating body 14 fits into the circular groove 54 of the skeleton material 51, and the round tenon 24 of the metal fitting 21 fits into the tenon hole 19 of the penetrating body 14. Can be prevented.

  As shown in the cross section of FIG. 5, there is a gap between the siding board 41 and the arm 61, and most of the rainwater poured around the arm 61 falls from here. The rainwater adhering to the penetrating body 14 is also dammed by the contact plate 46 and does not enter the inside. As described above, in the present invention, the cutout 43 formed on the siding board 41 is closed with the contact plate 46, so that a sealing material is unnecessary, labor and time during construction can be reduced, and maintenance of the sealing material is also unnecessary. In addition, the elastic body 17 and the contact | adherence board 46 can ensure long-term reliability by using the material excellent in weather resistance.

  FIG. 6 shows a specific example of a support structure different from FIG. Also in this figure, the skeleton material 51 and the arm 61 face each other across the siding board 41, and both are integrated by the connecting tool 31, but the connecting tool 31 is a U-shape formed by bending a steel plate at two locations. Thus, the contact plate 32 that contacts the frame material 51 and the upright plate 33 that is inserted into the slit 63 processed into the arm 61 are integrated.

  The contact plate 32 is in contact with the side surface of the skeleton material 51 and is provided with round holes 38 at two upper and lower positions in order to insert the shaft portion of the long bolt 59. In addition, the frame material 51 has a machined hole 53 for inserting the long bolt 59, and a counterbore 52 is machined at the end of the medium hole 53 to accommodate the head of the long bolt 59 and the washer 58. It is. When a long bolt 59 is inserted from the back surface of the skeleton material 51, its tip protrudes from the round hole 38, and a nut 39 is screwed and tightened thereto, the contact plate 32 comes into close contact with the skeleton material 51, and the coupling tool 31. Is fixed.

  The penetrating body 34 and the upright plate 33 of the connector 31 are integrated without any breaks, but for convenience, the range inserted into the slit 63 of the arm 61 is referred to as the upright plate 33 and the base side is referred to as the penetrating body 34. The penetrating body 34 extends from the contact plate 32, passes through the siding board 41, and protrudes to the outside. It is the same as FIG. 1 that the upright plate 33 is inserted into the slit 63 of the arm 61 and both are integrated by the pin 69. Therefore, the upright plate 33 is provided with a pin hole 36 and a pin groove 35, and a lateral hole 65 is processed on the side surface of the arm 61.

  The contact plate 48 has a simple rectangular shape, and is provided with a rectangular window hole 49 that extends thinly and vertically in order to insert the penetrating body 34. When the penetrating body 34 is inserted into the window hole 49, the contact plate 48 can be displaced using the penetrating body 34 as a guide, but there is no gap in the window hole 49 to prevent intrusion of rainwater. Further, the siding board 41 is provided with two rows of cutouts 44 corresponding to the penetrating body 34, but this size has a margin with respect to the penetrating body 34. In this figure, the cutouts 44 are arranged in two rows, but if the distance between the two penetrating bodies 34 is narrower, the left and right cutouts 44 can be integrated.

  The elastic body 37 is disposed between the contact plate 32 and the contact plate 48, but is inserted into the shaft portion of the long bolt 59 to prevent the drop off. Therefore, the extension of the long bolt 59 is increased so as to penetrate between the two through bodies 34. Due to the reaction force of the elastic body 37, the contact plate 48 is in close contact with the siding board 41 and completely blocks the cutout 44. The cutout 44 of the siding board 41 is not limited to a closed shape as shown in this figure, and may be an open shape that reaches the end surface of the siding board 41.

  FIG. 7 shows a step in the middle of assembling each element of FIG. The coupling tool 31 is fixed to the skeleton material 51 using the long bolt 59 and the nut 39, and the elastic body 37 is assembled near the tip of the long bolt 59 protruding from the nut 39, and then into the window hole 49 of the contact plate 48. The penetrating body 34 is inserted. When the siding board 41 is continuously spread, the elastic body 37 is compressed, and the adhesion plate 48 is brought into close contact with the siding board 41 by the reaction force, thereby ensuring the sealing property.

  FIG. 8 shows a final stage in which the elements shown in FIG. 6 are assembled. The upright plate 33 is inserted into the slit 63 of the arm 61, and a pin 69 is driven from the side surface of the arm 61, so that the connector 31 and the arm 61 are integrated. As a result, the arm 61 is supported by the skeleton material 51 via the connector 31 and the elastic body 37 is compressed, and the contact plate 48 contacts the siding board 41 by the reaction force. In addition, the driving position of the pin 69 is adjusted so that a gap is generated between the siding board 41 and the arm 61, and the entire arm 61 is disposed outside the siding board 41.

  FIG. 9 shows the case where a balcony is installed on the side of a building using the present invention. The arm 61 is held imaginarily by the support structure shown in FIGS. 1 and 6, and protrudes outward without contacting the siding board 41. A balcony is completed by installing floor boards, handrails, and the like using the arms 61. As shown in FIGS. 5 and 8, the support structure blocks the cutouts 43 and 44 of the siding board 41 with the contact plates 46 and 48, thereby preventing rainwater from entering.
