Description

[Technical Field]

[0001] The present invention relates to a lattice screen that covers the exterior wall of the upper floor chianti section to the lower end of the exterior wall of the lower floor chianti section in a building that has chianti sections formed in a cantilever structure at the same top and bottom positions on the upper and lower floors and protruding to the outdoors. [Background technology]

[0002] In buildings that have cantilevered sections on the ceilings of the upper and lower floors that move up and down, such as the verandas of an apartment building, that protrude outdoors, a lattice screen in the form of a lattice plate is sometimes attached to cover the outdoor wall of the cantilevered section on the upper floor, covering the outdoor wall of the cantilevered section on the lower floor, in order to achieve various effects such as improving the exterior design, reducing sunlight, and providing privacy.

[0004] [Patent Document 1] JP 2016-65445 A Summary of the Invention [Problem to be solved by the invention]

[0005] In order to improve the appearance design of the lattice screen, the plurality of long vertical lattice members that form the lattice screen may be wrapped with a wood grain finish, for example, to create a wood-like appearance.

[0006] In addition, in some buildings, the height between the lower and upper floors can be increased to enhance the sense of openness within the interior space. In this case, the lattice screen must be made longer in the vertical direction in accordance with the increase in the floor height between the upper and lower floors.

[0007] However, the wrapping process applied to lattice screens has limitations on the length that can be wrapped due to limitations in the technique, and in lattice screens that are formed to have a longer vertical length as the floor height between the upper and lower floors increases, it may be impossible to apply wrapping to the vertical lattice material.

[0008] Furthermore, as the floor height between the upper and lower floors increases, the lattice screen is formed to have a longer vertical length, and the longer the vertical length, the heavier it becomes, which can make it difficult to install in the cantilever section.

[0009] The present invention has been made in consideration of the above circumstances, and aims to provide a lattice screen that can be subjected to wrapping processing to improve the appearance design even when the lattice screen has a long vertical length, and that allows the lattice screen to be easily attached to the cantilever section. [Means for solving the problem]

[0010] In order to solve the above problems, the grid screen according to the present invention Installation structureIn a building having cantilevered ceiling sections at the same top and bottom positions on the ceiling sections of an upper floor and a lower floor, each having a cantilevered structure that protrudes outdoors, the lattice screen covers from the outdoor wall of the cantilevered ceiling section of the upper floor to the lower end of the outdoor wall of the cantilevered ceiling section of the lower floor, the lattice screen comprising a first lattice unit in the form of a lattice plate and a second lattice unit in the form of a lattice plate, the first lattice unit and the second lattice unit comprising a plurality of vertical lattice members that have been wrapped, the upper part of the first lattice unit being fixed to the cantilevered ceiling section of the upper floor and the lower part being fixed to the cantilevered ceiling section of the lower floor, and the upper and lower parts of the second lattice units being fixed to the cantilevered ceiling section of the lower floor so as to be aligned below the first lattice unit and cover the lower end of the outdoor wall of the cantilevered ceiling section of the lower floor. The cantilever section of the lower floor is formed by dividing the outdoor wall into two parts, an upper part and a lower part, and the boundary between the first lattice unit and the second lattice unit is fixed so that it overlaps with the boundary between the upper and lower parts of the outdoor wall of the cantilever section of the lower floor. It is characterized by the following.

[0011] Furthermore, the first lattice unit and the second lattice unit are provided with a plurality of horizontal lattice members long in the horizontal direction for fixing the plurality of vertical lattice members, and the plurality of horizontal lattice members fix the upper portions of the plurality of vertical lattice members of the first lattice unit together in the longitudinal direction, and a horizontally long frame is formed inside the cantilever section of the upper floor along the outdoor wall of the cantilever section. (10U) a first fixing metal fitting fixed to the wall of the cantilever portion and protruding from the outdoor wall of the cantilever portion to the outdoor side; (30a) Horizontal lattice material fixed to (25a) and a horizontally long frame formed inside the cantilever section of the lower floor along the outdoor wall of the cantilever section by fixing the lower portions of the longitudinal direction of the plurality of vertical lattice members of the first lattice unit to each other. (10L) The first fixing bracket is fixed to (39c) a first fixing metal fitting placed on the top surface of the cantilever portion and projecting from the outdoor-side wall of the cantilever portion to the outdoors; (30b) Horizontal lattice material fixed to (25b)and a horizontal lattice member (25c) that fastens the upper portions of the plurality of vertical lattice members of the second lattice unit together in the longitudinal direction and is fixed to a horizontally long frame (10L) inside the canty part of the lower floor along the outdoor wall of the canty part and is fixed to a first fixing metal fitting (30c) that protrudes from the outdoor wall of the canty part toward the outdoors, and a horizontal lattice member that fastens the lower portions of the plurality of vertical lattice members of the second lattice unit together in the longitudinal direction and is fixed to a second fixing metal fitting that is fixed to the outdoor wall of the lower canty part and protrudes from the outdoor wall toward the outdoors. (25d) and

[0012] Furthermore, the second lattice unit The lower part of the Chianti section of the lower floor The second lattice unit is fixed to the second fixing bracket, which has two members: a base portion that abuts against and is fixed to the outdoor wall, and a second lattice unit fixing portion that is fixed to the base portion and fixes the second lattice unit.The tilt can be adjusted by adjusting the position of the second lattice unit fixing portion that is fixed to the base portion along the outdoor direction.

[0013] Furthermore, the second lattice unit The lower part of the Chianti section of the lower floor The fixing device is fixed to the outdoor wall by driving a fixing device into the outdoor wall from the outdoor side, and is fixed to the second fixing bracket having the base portion equipped with an unevenness adjustment sheet that is flexible in the thickness direction at the point where it abuts the outdoor wall. [Effects of the Invention]

[0014] According to the lattice screen of the present invention, the lattice screen is divided vertically into a first lattice unit and a second lattice unit. Therefore, even if the vertical length of the lattice screen is longer than the limit of the length that can be wrapped, the entire lattice screen can be wrapped by wrapping each of the first lattice unit and the second lattice unit. Furthermore, because the lattice screen is divided into a first lattice unit and a second lattice unit, the installation of the first lattice unit and the installation of the second lattice unit can be performed separately, making the installation of the lattice screen easier. Furthermore, because the boundary between the first lattice unit and the second lattice unit overlaps with the outdoor wall of the cantilever section of the lower floor, the boundary is not noticeable, preventing a deterioration in the exterior design.

[0015] Furthermore, the first lattice unit is stably attached to the chianti section by having its upper and lower parts fixed to the building frame, while the second lattice unit, which is shorter in the vertical direction and lighter than the first lattice unit, is stably attached to the chianti section by having its upper part fixed to the building frame and its lower part fixed to the outdoor wall of the chianti section of the lower floor. Also, because the lower part of the second lattice unit is fixed to the outdoor wall of the chianti section of the lower floor, there is no need to consider the internal structure of the chianti section of the lower floor when installing the second lattice unit.

[0016] Furthermore, the position of the fixing part of the second fixing bracket fixed to the base can be adjusted toward the outdoors, allowing the tilt of the second lattice unit to be adjusted. Therefore, if the first lattice unit and the second lattice unit lined up at the bottom of the first lattice unit are not parallel, the second lattice unit can be adjusted so that it is parallel to the first lattice unit, preventing the first and second lattice units from becoming non-parallel and reducing the appearance design.

[0017] Furthermore, by providing an unevenness adjustment sheet that is flexible in the thickness direction on the surface of the base that abuts the outdoor wall of the cananti part, even if the outdoor wall of the cananti part to which the base is fixed is not flat, such as when an exterior wall material with an uneven pattern is provided on the outdoor wall of the cananti part, the unevenness adjustment sheet is pressed against the outdoor wall of the cananti part and deforms to follow the unevenness of the outdoor wall of the cananti part, so the base can be stably fixed to the outdoor wall of the cananti part.

[0023] Next, we will explain the lattice screen 20 according to the present invention.

As shown in FIG. 9, the horizontal lattice members 25b are provided with fixing holes 27b for securing to first fixing brackets 30b (described later), and the fixing holes 27b are positioned in the gaps between two adjacent vertical lattice members 23a when the vertical lattice members 23a are secured to the horizontal lattice members 25b.

[0027] 2 and 3(b), the second lattice unit 22 is formed into a lattice plate shape by a plurality of vertical lattice members 23b that are vertically elongated members arranged at equal intervals with gaps between them and that have been wrapped with a wood grain pattern, and a plurality of horizontal lattice members 24b that are horizontally elongated and that secure the vertical lattice members 23b.

The multiple vertical lattice members 23b are secured to each other by fastening each vertical lattice member 23b to the vertical lattice member fixing portions 26c with fasteners such as screws 84. As shown in FIG. 9, the horizontal lattice members 25c are provided with fixing holes 27c for securing the horizontal lattice members 25c to the first fixing brackets 30c (described later), and the fixing holes 27c are positioned in the gaps between two adjacent vertical lattice members 23b when the vertical lattice members 23b are secured to the horizontal lattice members 25c.

[0029] Furthermore, the horizontal lattice member 25d, which fixes the lower portions of the longitudinal direction of the multiple vertical lattice members 23b among the multiple horizontal lattice members 24b of the second lattice unit 22 and to which the second lattice unit fixing portion 57 of the second fixing bracket 50 described later is attached, is a long, rod-shaped member with an external thread that penetrates each vertical lattice member 23b horizontally and fixes them, as shown in Figures 2 and 3(b).

[0030] Next, we will explain the structures of the first fixing brackets 30 and second fixing brackets 50 for fixing the lattice screen 20 to the canty section 2 of the building 1.

[0031] As shown in FIG. 4, the first fixing metal fitting 30a for fixing the upper part of the first lattice unit 21 to the cantilever part 2U of the upper floor UF comprises a plate-like fixing part 31a extending horizontally and having fixing holes 32a, a rising part 36 which is an elongated square pipe and has drainage holes 37 on the side and is fixed to the upper surface of the fixing part 31a by welding, a plate-like protrusion 33a extending vertically and having one side fixed to the side surface of the lower part of the rising part 36 by welding, and a plate-like protrusion 33a extending vertically and having fixing holes 35a with female threads and one side of which is fixed to the tip of the protrusion 33a. the first reinforcing part 38, which is a plate-like part that extends horizontally and has a fixing hole 39 with a female thread cut therein and whose underside is fixed to the upper end of the rising part 36 by welding; and two second reinforcing parts 40, which are plate-like parts that are bent at a right angle to form an L-shape with one flat plate part and the other flat plate part, and have a groove 41 in one of the flat plate parts, and are fixed by welding to two opposing side surfaces in the vertical middle of the rising part 36 so that one flat plate part is parallel to the fixing part 34a.

An EPT (ethylene propylene rubber) unevenness adjustment sheet 54 is attached to the surface of one flat plate portion 52 that abuts against the outdoor wall 3L of the cantilever portion 2L of the lower floor LF.

[0036] As shown in Figure 7, the second lattice unit fixing portion 57 comprises a position adjustment portion 58 which is plate-shaped and fixed to the base portion 51, and which has a position adjustment hole 59 which is a long hole; a fixing portion 60 which is plate-shaped and has a fixing hole 61 which bends downward from the tip of the position adjustment portion 58 in the outdoor direction 98 and is fixed to the vertical lattice member 23b of the second lattice unit 22; and a mounting portion 62 which is plate-shaped and has a mounting hole 63 which bends further from the fixing portion 60 in the outdoor direction 98 and is attached to the horizontal lattice member 25d of the second lattice unit 22.

[0037] Next, we will explain how the first fixing bracket 30 is fixed to the canty section 2, and the lattice screen 20 fixed to the first fixing bracket 30. As shown in Figure 8, the first fixing bracket 30a, which is used to fix the upper part of the first lattice unit 21 to the canty section 2U of the upper floor UF, is fixed to the beam 10U by placing the fixed portion 31a on the upper surface of the upper flange 11 of the beam 10U inside the canty section 2U of the upper floor UF, inserting a bolt 82, which serves as a fixing device, into the fixed hole 32a of the fixed portion 31a and the fixing hole 12 provided in the upper flange 11 of the beam 10U, and tightening a nut 83, which serves as a fixing device, from the tip of the bolt 82.

[0038] Furthermore, when the first fixing bracket 30a is fixed to the beam 10U, the protrusion 33a protrudes from the inside of the cantilever portion 2U of the upper floor UF toward the outdoors 98 and out to the outdoors 99, the upper surface of the first reinforcing portion 38 abuts against the cantilever fixing bracket 17 for fixing the cantilever 16 to the upper end of the parapet portion 15, and one plate portion of the second reinforcing portion 40 is formed to abut against the structural plywood 6 of the cantilever portion 2U of the upper floor UF, and the cantilever 16 is reinforced by the first fixing bracket 30a by threading a bolt 82, which is a fixing device, into the fixing hole 39 of the first reinforcing portion 38 and the fixed hole 18 provided in the cantilever fixing bracket 17. Furthermore, the structural plywood 6 is reinforced by the first fixing bracket 30a by threading a bolt 82, which is a fixing device, from the second reinforcing part 40 side into a female-threaded fixing hole 9 provided in the plate material 8 that is arranged to sandwich the structural plywood 6 between the second reinforcing part 40, a groove portion 41 in the second reinforcing part 40, and a fixing hole 7 provided in the structural plywood 6.

[0039] As shown in Figure 8, the upper part of the first lattice unit 21 is fixed to the beam 10U of the canty portion 2U of the upper floor UF via the first fixing bracket 30a by overlapping the horizontal lattice member 25a provided on the upper part of the first lattice unit 21 with the fixing portion 34a of the first fixing bracket 30a that protrudes outside 99, and by inserting a bolt 82, which serves as a fixing device, through the gap between the two adjacent vertical lattice members 23a into the fixing hole 27a of the horizontal lattice member 25a and the fixing hole 35a of the fixing portion 34a towards the canty portion 2U and fixing the horizontal lattice member 25a at the upper part of the first lattice unit 21 to the fixing portion 34a of the first fixing bracket 30a.

[0040] As shown in Figure 9, the first fixing bracket 30c for fixing the upper part of the second lattice unit 22 to the cantilever portion 2L of the lower floor LF is fixed to the beam 10L by overlapping the fixed portion 31c with the stiffener 13 provided on the beam 10L of the cantilever portion 2L of the lower floor LF, inserting a bolt 82 as a fixing device into the fixed hole 32c of the fixed portion 31c and the fixing hole 14 provided in the stiffener 13 of the beam 10L, and tightening a nut 83 as a fixing device from the tip of the bolt 82.

[0041] Furthermore, as shown in Figure 9, the first fixing bracket 30b for fixing the lower part of the first lattice unit 21 to the cantilever portion 2L of the lower floor LF is fixed to the beam 10L via the first fixing bracket 30c by placing the fixed portion 31b on the upper surface of the second fixing portion 43 of the first fixing bracket 30c, and inserting and twisting the fixing bolt 82 from above into the fixed hole 32b of the fixed portion 31b of the first fixing bracket 30b and the fixing hole 44 of the second fixing portion 43 of the first fixing bracket 30c.

[0042] Furthermore, when the first fixing bracket 30c is fixed to the beam 10L, the protrusion 33c is formed so that it protrudes from the inside of the cantilever portion 2L of the lower floor LF in the outdoor direction 98 to the outdoors 99, and when the first fixing bracket 30b is fixed to the beam 10L via the first fixing bracket 30c, the protrusion 33b is formed so that it protrudes from the inside of the cantilever portion 2L of the lower floor LF in the outdoor direction 98 to the outdoors 98.

[0043] As shown in Figure 9, the lower part of the first lattice unit 21 is fixed to the beam 10L of the canty section 2L of the lower floor LF via the first fixing device 30b by overlapping the horizontal lattice member 25b provided at the lower part of the first lattice unit 21 with the fixing portion 34b of the first fixing bracket 30b that protrudes outside 99, and by inserting a bolt 82, which serves as a fixing device, through the gap between two adjacent vertical lattice members 23a into the fixing hole 27b provided in the horizontal lattice member 25b and the fixing hole 35b of the fixing portion 34b towards the canty section 2L, and fixing the horizontal lattice member 25b at the bottom of the first lattice unit 21 to the fixing portion 34b of the first fixing bracket 30b.

[0044] Furthermore, as shown in Figure 9, the upper part of the second lattice unit 22 is fixed to the beams 10L of the canty section 2L of the lower floor LF via the first fixing bracket 30c by overlapping the horizontal lattice member 25c provided at the upper part of the second lattice unit 22 with the fixing portion 34c of the first fixing bracket 30c that protrudes outside 99, and by inserting a bolt 82, which serves as a fixing device, through the gap between two adjacent vertical lattice members 23b into the fixing hole 27c provided in the horizontal lattice member 25c and the fixing hole 35c of the fixing portion 34c, and fixing the horizontal lattice member 25c at the upper part of the second lattice unit 22 to the fixing portion 34c of the first fixing bracket 30c.

[0045] As shown in Figures 8 and 9, the position of the outdoor wall 3 of the cantilever section 2 where the protruding portions (33a, 33b, 33c) of each first fixing bracket 30 protrude to the outdoors 99 is waterproofed using caulking material 80, and further, as shown in Figures 8 and 9, a plate-shaped water-repellent material 70 that bends toward the cantilever section 2 and then bends vertically is fixed so as to be sandwiched between the fixing portions (34a, 34b, 34c) of each first fixing bracket 30 and each horizontal lattice member (25a, 25b, 25c) fixed to the fixing portions (34a, 34b, 34c), and waterproofing is performed between each water-repellent material 70 and the outdoor wall 3 of the cantilever section 2 using gap tape 81 and caulking material 80.

[0046] Next, we will explain how the lower part of the second lattice unit 22 is fixed to the cantilever portion 2L by the second fixing bracket 50. As shown in Figure 10, the second lattice unit fixing portion 57 of the second fixing bracket 50 is attached to the lower part of the second lattice unit 22 so that its mounting portion 62 abuts against the opposing side surfaces of the two vertical lattice members 23b of the second lattice unit 22, and the horizontal lattice members 25d that fix the lower parts of the vertical lattice members 23b to each other in the longitudinal direction pass through mounting holes 63, and is fixed to the lower part of the second lattice unit 22 by driving screws 84, which serve as fixing devices, into the vertical lattice members 23b and into fixing holes 61 of the fixing portion 60, as shown in Figure 9.

[0047] As shown in Figure 9, the base portion 51 of the second fixing bracket 50 is fixed to the lower portion 5 of the outdoor wall 3L of the cantilever portion 2L of the lower floor LF by abutting one flat plate portion 52 against the lower portion 5 of the outdoor wall 3L of the cantilever portion 2L of the lower floor LF and driving a fixing screw 84 into the fixing hole 53 and the outdoor wall 3L of the cantilever portion 2L of the lower floor LF. The base part 51 is fixed to the outdoor wall 3L of the cantilever part 2L so that the other flat plate part 55 overlaps the position adjustment part 58 of the second lattice unit fixing part 57 fixed to the second lattice unit 22, and by inserting a bolt 82 as a fixing device into the fixing hole 56 of the other flat plate part 55 of the base part 51 and the position adjustment hole 59 of the position adjustment part 58 of the second lattice unit fixing part 57 and tightening a nut 83 as a fixing device from the tip of the bolt 82 to fix the second lattice unit fixing part 57 to the base part 51, the lower part of the second lattice unit 22 is fixed to the lower part 5 of the outdoor wall 3L of the cantilever part 2L of the lower floor LF via the second fixing bracket 50.

[0048] As shown in Figures 7(a) and 7(b), the second fixing bracket 50 is capable of moving the position at which the second lattice unit fixing portion 57 is fixed to the base portion 51 along the position adjustment hole 59, which is a long hole in the position adjustment portion 58, and the position adjustment hole 59 is formed so as to be a long hole facing toward the outdoors 98 when the second lattice unit 22 is fixed to the cantilever portion 2 of the lower floor LF by the second fixing bracket 50. Therefore, when the first lattice unit 21 and the second lattice unit 22 are fixed to the cantilever sections 2 of the upper floor UF and the lower floor LF, it is checked whether the first lattice unit 21 and the second lattice unit 22 are parallel, and if the first lattice unit 21 and the second lattice unit 22 are not parallel, the position at which the second lattice unit fixing section 57 of the second fixing bracket 50 is fixed to the base section 51 can be adjusted along the position adjustment hole 59, which is a long hole in the position adjustment section 58, to adjust the inclination of the second lattice unit 22, and make the first lattice unit 21 and the second lattice unit 22 parallel.

[0049] Furthermore, as shown in Figure 8, the height of the upper end of the first lattice unit 21 is the same as the upper end of the parapet portion 15 of the chianti portion 2U of the upper floor UF, and as shown in Figure 9, the boundary between the lower end of the first lattice unit 21 and the upper end of the second lattice unit 22 is the same height as the outdoor wall 3L of the chianti portion 2L of the lower floor LF, and the height of the lower end of the second lattice unit 22 is located slightly below the lower end of the chianti portion 2L of the lower floor LF, so that the entire lattice screen 20 covers from the upper end of the outdoor wall 3U of the chianti portion 2U of the upper floor UF of the building 1 to the lower end of the outdoor wall 3L of the chianti portion 2L of the lower floor LF.

[0050] 4 to 6, the shape of the first fixing metal fitting 30 in this embodiment is as shown, but the present invention is not limited to this. The shape of the first fixing metal fitting 30 is limited by the internal structure of the cantilever section 2, so it may have a shape like the first fixing metal fitting 30 shown in Fig. 11, as long as it has a fixed portion 31 that is fixed directly or indirectly to the beam 10, a protruding portion 33 that protrudes from the inside of the cantilever section 2 to the outdoors 99, and a fixing portion 34 that fixes the lattice screen outdoors 99.
