Description

  The present invention relates to an inner wall panel fixing bracket for fixing an inner wall panel to a building frame in an inner wall portion of a building such as a house, and in particular, a heat insulating material provided to cover the outdoor side surface of the inner wall frame is connected to the inner wall frame and the frame assembly. It is related with the inner wall panel fixing metal fitting which can be filled easily and reliably in the space between.

  Conventionally, an inner wall portion in a building such as a house is configured by sequentially attaching inner wall panels between a plurality of shaft sets provided at predetermined intervals. Generally, the inner wall panel is attached to the shaft assembly by fixing both end portions of the inner wall panel to the shaft assembly using fixing brackets. FIG. 13 is a schematic perspective view showing the structure of the inner wall 80 according to a conventional example (see Patent Document 1). As shown in the figure, the inner wall portion 80 includes an inner wall panel 83 including an inner wall frame 81 framed with wood or the like and a heat insulating material 82 provided so as to cover the back surface of the inner wall frame 81. It is configured by being fixed to the shaft set 85 by a fixing bracket 84.

  The inner wall panel fixing bracket 84 includes a base 86 for mounting on the shaft assembly 85, a bolt 87 screwed to the base 86, a spacer 88 formed by bending both ends of the metal plate approximately 90 ° to form a bent portion 88a. Are provided. On the other hand, the heat insulating material 82 constituting the inner wall panel 83 has a thickness larger than the length of the spacer 88, and the back surface of the inner wall frame 81 is placed so that both ends thereof are at the same positions as both ends of the inner wall frame 81. It is attached in a covered state.

  When fixing the inner wall panel 83 to the shaft set 85, the base wall 86 of the inner wall panel fixing bracket 84 is locked to the shaft set 85, and one bent portion 88a of the spacer 88 is brought into contact with the shaft set 85. And attached to the shaft set 85. Thereafter, the inner wall panels 83 are respectively attached to the left and right sides of the inner wall panel fixing bracket 84. At that time, the outer side surface of the inner wall frame 81 is brought into contact with the other bent portion 88a of the spacer 88, and the heat insulating material 82 is pushed into the space 89 between the inner wall frame 81 and the shaft assembly 85 to thereby change the inner wall panel 83. Install. Thereafter, the bolt 87 is screwed in until its head abuts against the indoor side surface 83 a of the inner wall panel 83. Thereby, the inner wall panel 83 is pressed against the shaft set 85 by being pressed to the outdoor side by the head of the bolt 87, and is fixed.

  In this way, the inner wall panel 83 is fixed to the shaft set 85 such that the inner wall frame 81 is spaced apart from the shaft set 85 by a predetermined distance, and the heat insulating material 82 is interposed between the inner wall frame 81 and the shaft set 85. Thus, heat conduction from the inner wall frame 81 to the shaft set 85 is suppressed. Thereby, compared with the case where the inner wall panel 83 is fixed by directly contacting the inner wall frame 81 with the shaft set 85, heat loss from the indoor to the outdoor is reduced, and the heat insulating performance of the inner wall 80 is improved. It is possible.

As shown in FIGS. 7 and 8, the inner wall panel fixing bracket 4 includes a base plate 13 disposed so as to be along the indoor side surface of the shaft set 2, and a shaft set provided so as to protrude from the back side of the base plate 13. 2, a locking member 14 that is locked to the outdoor side surface, a spacer 17 in which the pipe member 16 is fitted and fixed to the inner wall frame backing plate 15, and determines the fixing position of the heat insulating inner wall panel 3. A coil spring 18 that is externally fitted to a portion protruding from the back surface of the inner wall frame backing plate 15, one end fixed to the surface of the substrate 13 and the other end fixed to the inner wall frame backing plate 15, and a pipe member of the spacer 17 A fixing bolt 19 that is inserted into 16 and screwed from the surface side of the substrate 13 and an inner wall frame pressing plate 20 that is mounted near the head of the fixing bolt 19 are provided. In the present invention, the front and back surfaces of the substrate 13 and the inner wall frame backing plate 15 mean the indoor side surface and the outdoor side surface when the inner wall panel fixing bracket 4 is attached to the shaft assembly 2.

  As shown in FIGS. 7 and 8, the substrate 13 is formed by bending the upper and lower ends of a substantially rectangular steel plate approximately 90 ° on the back surface side to form a bent portion 13 a. At the center in the width direction of each of the upper and lower bent portions 13a, a fitting protrusion 13b is provided so as to protrude into the gap 21 between the adjacent shaft sets 2 as shown in FIG. It has a shape to fit. Thus, when the inner wall panel fixing bracket 4 is attached to the shaft assembly 2, the board 13 is arranged so that the fitting protrusion 13 b is fitted in the gap 21 of the shaft assembly 2. It is possible to prevent displacement in the horizontal direction. Further, as shown in FIG. 8, an insertion hole 13 c for inserting the locking member 14 is provided in the central portion in the width direction of the substrate 13, and the fixing bolt 19 is screwed in the vertical lower part thereof. Screw holes 13d are respectively formed.

  As shown in FIG. 8, the locking member 14 is formed by providing a threaded portion 14 a at one end of a steel round bar and a widened portion 14 b at the other end. The locking member 14 has an outer diameter of the round bar portion and the screw portion 14a smaller than the width of the gap 21 of the shaft assembly 2, and the widened portion 14b is wider than the width of the gap 21 in plan view. Thus, it is formed so as to be narrower than the width of the gap 21 in a side view. Accordingly, the locking member 14 can pass through the gap 21 when the widened portion 14b is in the vertical direction, and cannot pass through the gap 21 when the widened portion 14b is in the horizontal direction. Yes. Further, the length of the locking member 14 is slightly longer than the depth of the gap 21. As shown in FIGS. 7 and 8, the locking member 14 configured as described above is inserted into the insertion hole 13 c from the back surface side of the substrate 13, and the nut 22 is provided on the screw portion 14 a protruding to the front surface side of the substrate 13. By being screwed together, it is fixed to the substrate 13.

  The spacer 17 is for separating the heat insulating inner wall panel 3 from the shaft assembly 2 by a predetermined distance. As shown in FIG. 8, the spacer 17 supports the inner wall frame backing plate 15 that supports the heat insulating inner wall panel 3 from the outdoor side, and heat insulation. A pipe member 16 for securing a predetermined distance between the inner wall panel 3 and the shaft assembly 2 is provided. The inner wall frame backing plate 15 is formed by bending both left and right end portions of a rectangular steel plate by approximately 90 °, and forming a fitting insertion hole 15a for fitting the pipe member 16 into the center portion in the width direction. As shown in FIG. 3, the left and right ends of the inner wall frame backing plate 15 constitute an inner wall frame 8 for each heat insulating inner wall panel 3 built on both the left and right sides of the inner wall panel fixing bracket 4. The vertical pillar 6 is supported from the outdoor side by abutting on the outdoor side surface. Accordingly, the width of the inner wall frame backing plate 15 is determined in consideration of the width of the vertical column 6 and the width of the joint 23 provided between the left and right heat insulating inner wall panels 3 so that the left and right vertical columns 6 can be reliably supported. ing.

  As shown in FIG. 8, the pipe member 16 is a square steel pipe having a substantially rectangular cross-sectional shape, and the thickness thereof is such that the fixing bolt 19 can be inserted. The pipe member 16 is inserted into the insertion hole 15a of the inner wall frame backing plate 15 so as to be orthogonal to the inner wall frame backing plate 15, and is fixed by welding or the like. As shown in FIG. 5, the heat insulating inner wall panel 3 supported from the outdoor side by the inner wall frame backing plate 15 by the outdoor side end portion 16 a of the pipe member 16 being in contact with the surface of the substrate 13 is further increased. It cannot move to the outdoor side, and a predetermined distance is secured between the heat insulating inner wall panel 3 and the shaft assembly 2. At this time, the separation distance from the shaft assembly 2 of the heat insulating inner wall panel 3 depends on the length of a portion (hereinafter referred to as “back surface side protruding portion”) 16 b of the pipe member 16 protruding from the back surface of the inner wall frame backing plate 15. It is determined. On the other hand, the length of the portion 16c of the pipe member 16 that protrudes from the surface of the inner wall frame backing plate 15 (hereinafter referred to as the “surface-side protruding portion”) is such that the inner wall frame backing plate 15 is as shown in FIG. In a state in which the vertical column 6 is in contact with the outdoor side surface, the indoor side end portion 16 d of the pipe member 16 does not protrude from the stepped portion 6 b of the vertical column 6 to the indoor side. Accordingly, when the inner wall frame pressing plate 20 is disposed in the stepped portion 6b, the indoor side end portion 16d of the pipe member 16 does not interfere with the inner wall frame pressing plate 20. In this embodiment, a square steel pipe is used as the pipe member 16, but the present invention is not limited to this. For example, a round steel pipe having a circular cross section or the like can also be used.

  The coil spring 18 is for urging the inner wall frame backing plate 15 in the direction opposite to the substrate 13. As shown in FIGS. 7 and 8, the coil spring 18 is provided by being fitted on the rear surface side protruding portion 16 b of the pipe member 16, one end on the surface of the substrate 13 and the other end on the inner wall frame backing plate 15. Each of them is in contact with the back surface. As shown in FIG. 2, the length of the coil spring 18 is such that the initial length L1 in the state where no external force is applied is approximately twice the length of the rear surface side protruding portion 16b of the pipe member 16, and As shown in FIG. 5, the length L <b> 2 in the most contracted state when the compression force is applied is substantially equal to or slightly smaller than the length of the rear surface side protruding portion 16 b of the pipe member 16. As a result, the spacer 17 is in a state where the inner wall frame backing plate 15 is separated from the substrate 13 by the initial length L1 of the coil spring 18 when no external force is applied. In this case, regardless of the presence of the coil spring 18, the outdoor side end 16 a of the pipe member 16 can move until it abuts against the surface of the substrate 13. Moreover, it is preferable that the coil spring 18 has an urging force that does not hinder the movement of the spacer 17 to the outdoor side.

  The fixing bolt 19 presses the heat insulating inner wall panel 3 to the outdoor side via the inner wall frame pressing plate 20 and fixes it at a predetermined position. As shown in FIG. 8, the fixing bolt 19 has a head portion 19a and a long shaft portion 19b. A screw is formed over the entire length of the shaft portion 19b, and a plus driver PD is inserted into the head portion 19a. For this purpose, a cross-shaped groove 19c is formed. Here, as shown in FIG. 3, the head portion 19 a is slightly larger than the opening of the pipe member 16 and slightly smaller than the width of the joint 23 provided between the adjacent heat insulating inner wall panels 3. Further, as shown in FIG. 2, the shaft portion 19 b has an outer diameter smaller than the width of the gap 21 of the shaft set 2, and its length is equal to the initial length L1 of the coil spring 18 and the pipe member 16. It is sufficiently larger than the total length of the surface side protruding portion 16c. As shown in FIGS. 7 and 8, the shaft portion 19 b of the fixing bolt 19 is inserted into the pipe member 16, and the tip portion thereof is screwed into the screw hole 13 d from the surface side of the substrate 13. . At this time, the fixing bolt 19 can only be screwed in until the head 19a comes into contact with the opening of the pipe member 16 so that the inner wall frame pressing plate 20 can be attached to the base of the shaft 19b. The portion is slightly exposed. Further, as shown in FIG. 2, the tip end portion of the shaft portion 19b protruding from the back surface of the substrate 13 has the outer diameter of the shaft portion 19b smaller than the width of the gap 21 of the shaft assembly 2 as described above. It is to be inserted into the back of the.

  The inner wall frame pressing plate 20 is interposed between the head 19 a of the fixing bolt 19 and the vertical column 6, and transmits the pressing force received from the head 19 a of the fixing bolt 19 to the vertical column 6. It pushes to the outdoor side. As shown in FIGS. 7 and 8, the inner wall frame pressing plate 20 is formed by bending the upper and lower ends of a rectangular steel plate into a U-shape, and a pressing surface 20 a that presses the vertical column 6. The upper bent surface 20b and the lower bent surface 20c are substantially orthogonal to the pressing surface 20a. Here, the bending width of the upper bent surface 20b and the lower bent surface 20c is slightly smaller than the step of the stepped portion 6b formed in the vertical column 6, and the entire inner wall frame pressing plate 20 is accommodated in the stepped portion 6b. It can be done. Further, as shown in FIG. 8, a notch 20 d for mounting on the base portion of the shaft portion 19 b of the fixing bolt 19 is formed in the center portion in the width direction of the inner wall frame pressing plate 20. The notch 20d is formed from the lower bent surface 20c to the center in the height direction of the pressing surface 20a, and the uppermost portion has an arc shape in accordance with the shape of the shaft portion 19b of the fixing bolt 19. The lateral width of the notch 20d is substantially equal to the outer diameter of the shaft portion 19b of the fixing bolt 19. From the upper portion of the shaft portion 19b, the notch 20d is fitted to the root portion of the shaft portion 19b. By dropping the inner wall frame pressing plate 20, the inner wall frame pressing plate 20 can be inserted into the fixing bolt 19. Further, screw holes 20e are formed on both the left and right sides of the notch 20d in the pressing surface 20a, and the inner wall frame pressing plate 20 is fixed to the stepped portion 6b of the vertical column 6 with screws. In the present invention, as described above, the head 19a of the fixing bolt 19 is smaller than the width of the joint 23 between the heat insulating inner wall panels 3 adjacent to each other. Although the inner wall frame holding plate 20 is interposed, the fastening force of the fixing bolt 19 is increased by making the head portion 19a of the fixing bolt 19 larger than the width of the joint 23 and bringing the head portion 19a directly into contact with the vertical column 6. Can be transmitted to the heat insulating inner wall panel 3. However, the fastening force of the fixing bolt 19 can be more reliably transmitted to the heat insulating inner wall panel 3 by increasing the contact area with the vertical column 6 using the inner wall frame pressing plate 20 as in the present invention.

  Hereinafter, the construction procedure of the inner wall 1 according to the present embodiment will be described. First, the inner wall panel fixing metal fitting 4 in a state where the inner wall frame pressing plate 20 is not attached is attached to the shaft assembly 2. That is, as shown in FIG. 9, the locking member 14 of the inner wall panel fixing bracket 4 is inserted into the gap 21 of the shaft assembly 2 with the widened portion 14 b oriented vertically, and the widened portion 14 b extends to the outdoor side of the shaft assembly 2. After inserting until it protrudes, the locking member 14 is rotated 90 degrees and pulled toward the indoor side. Thereby, as shown in FIG. 1, the widened portion 14 b is locked to the outdoor side surface of the shaft assembly 2. In this state, as shown in FIG. 10, the substrate 13 is pressed against the shaft assembly 2 so that the upper and lower fitting protrusions 13 b are fitted in the gaps 21, and the nut 22 is tightened. As a result, the inner wall panel fixing bracket 4 is fixed to the shaft assembly 2. Further, although not shown in detail in the drawing, a plurality of inner wall panel fixing brackets 4 are sequentially attached at predetermined intervals along the shaft set 2 in the same manner.

  Next, the heat insulation inner wall panel 3 is built. That is, as shown in FIG. 10, the heat insulating inner wall panel 3 is placed from the left and right sides of the inner wall panel fixing bracket 4 fixed to the shaft assembly 2, and the inner wall frame backing plate 15 is placed along the outdoor side surface of the vertical column 6, and The joints 23 having a predetermined width are provided between the adjacent heat insulating inner wall panels 3. Here, as described above, since the easily deformable heat insulating material 9 is fixed to the vertical column 6 by the stud 12, as shown in FIG. 10, by grasping a place where the stud 12 is not present and pulling it away from the vertical column 6, A slight gap 24 can be formed between the easily deformable heat insulating material 9 and the vertical column 6. By inserting one end of the inner wall frame backing plate 15 into the gap 24, the inner wall frame backing plate 15 can be placed along the outdoor side surface of the vertical column 6. At this time, as shown in FIG. 3, the easily deformable heat insulating material 9 is pushed into the inner wall panel fixing bracket 4 side. Since a wide space corresponding to the initial length L1 of the coil spring 18 is secured between the inner wall frame backing plate 15 and the substrate 13, the easily deformable heat insulating material 9 is easily pushed.

  Next, the heat insulating inner wall panel 3 is fixed to the shaft assembly 2. That is, as shown in FIG. 11, the inner wall frame pressing plate 20 is attached to the root portion of the shaft portion 19b of the fixing bolt 19 so that the notch 20d is fitted to the shaft portion 19b, and the pressing surface 20a is attached. The vertical column 6 is brought into contact with the stepped portion 6b. Then, by inserting a Phillips screwdriver PD or the like into the cross groove 19c of the head 19a of the fixing bolt 19 and rotating it to the right, the fixing bolt 19 is screwed to the outdoor side. Along with this, the fastening force of the fixing bolt 19 is transmitted to the heat insulating inner wall panel 3 through the inner wall frame pressing plate 20, and the heat insulating inner wall panel 3 starts to move to the outdoor side, as shown in FIGS. Furthermore, when the outdoor side end 16a of the pipe member 16 contacts the surface of the substrate 13, the heat insulating inner wall panel 3 stops moving. In this state, the heat insulating inner wall panel 3 includes an inner wall frame pressing plate 20 that is pressed to the outdoor side by the fastening force of the fixing bolt 19, and an inner wall frame backing plate 15 that is pressed to the indoor side by the biasing force of the coil spring 18. And the position is fixed. On the other hand, the easily deformable heat insulating material 9 is elastically deformed along the shapes of the inner wall panel fixing bracket 4 and the shaft assembly 2 as the heat insulating inner wall panel 3 moves to the outdoor side, and when the fixing of the heat insulating inner wall panel 3 is completed, As shown in FIGS. 4 and 12, the space 11 between the vertical column 6 and the shaft assembly 2 is filled without a gap.

  Next, the finished state of the inner wall 1 is confirmed. That is, although details are not shown in the figure, the streets of the heat-insulated inner wall panel 3 are measured using a water thread or a cross line, and the building of the heat-insulated inner wall panel 3 is measured using a board ruler or the like. Check whether it is within the standard value.

  Finally, the position of the heat insulating inner wall panel 3 is finely adjusted according to the finished state. That is, when the measurement result of the building / street of the heat insulating inner wall panel 3 does not fall within the reference value, it is corrected to fall within the reference value. In this case, although details are not shown in the drawing, a plus driver PD or the like is inserted into the cross groove 19c of the head 19a of the fixing bolt 19 and rotated counterclockwise to slightly return to the indoor side. Along with this, the heat insulating inner wall panel 3 also moves slightly indoors, so that the position can be finely adjusted indoors. In this manner, after moving the heat insulating inner wall panel 3 to the indoor side by a desired distance, the building / street is measured again. If the measurement result does not fall within the reference value, the movement of the heat insulation inner wall panel 3 to the indoor side and the measurement on the building / street are repeated until the measurement result falls within the reference value.

  As described above, according to the inner wall panel fixing bracket 4 according to the present invention, the heat insulating inner wall panel 3 is built in a state in which the space 11 between the inner wall frame 8 and the shaft assembly 2 is widely secured, and then the house It can be moved to the outside and fixed to the shaft set 2 at a predetermined position. Therefore, when the heat insulating inner wall panel 3 is built, the easily deformable heat insulating material 9 provided so as to cover the outdoor side surface 8a of the inner wall frame 8 can be easily pushed into the space 11 between the inner wall frame 8 and the shaft assembly 2. The easily deformable heat insulating material 9 can be filled in the space 11 without a gap by a simple operation of simply screwing the fixing bolt 19 to the outdoor side. Thereby, the high heat insulation performance of the inner wall part 1 can be achieved easily and reliably. Further, after fixing the heat insulating inner wall panel 3 to the shaft assembly 2, the position of the heat insulating inner wall panel 3 can be finely adjusted to the indoor side by a simple operation from the indoor side according to the finished state. Thereby, a highly accurate finish can be achieved in the inner wall portion 1. In the present embodiment, the inner wall panel fixing bracket 4 is used to fix the heat insulating inner wall panel 3 to the shaft assembly 2 in the inner wall portion 1, but the shape of the substrate 13, the locking member 14 and the like is appropriately changed. Thus, it can be used as a fixing member for a panelized member at a place other than the inner wall portion 1.
