And after constructing each vertical fixing part 7, the upper fixing part 9, and the lower fixing part 11, the tacks 10 of each temporary fixing are removed, and as shown in FIGS. 5 and 6, between the frame 6 and the frame 3 Fill the mortar.

Next, the operation and effects of the opening building material 1 according to the present embodiment will be described.
As shown in FIG. 1, in the opening building material 1, in the vertical fixing portion 7, the vertical connecting member (connecting member) 17 is fixed to the vertical frame side fixing tool (the housing side fixing tool) 13 and the vertical frame side fixing tool (frame fixing The housing vertical surface 6a and the vertical frame (frame) 3a can be adhered and fixed only by placing the adhesive 15 between the fixtures 15 via the adhesive 23. That is, release the hand without continuing to hold the vertical connecting member against the vertical frame side fixing tool (the housing side fixing tool) 13 and the vertical frame side fixing tool (the frame side fixing tool) 15 until the adhesive 23 is cured. Can.
The longitudinal connection member 17 is, by its own weight, between the upper surface 25 of the vertical surface side fixture 13 of the casing and one lower surface 19 of the longitudinal connection member 17 and the upper surface 33 of the longitudinal frame side fixture 15 and the other of the vertical connection member 17 The adhesive strength between the lower surface 21 and the lower surface 21 is increased by the adhesive 23.
The longitudinal connecting member 17 changes the width L1 of the lower surface 19 of one and the width L2 of the lower surface 21 of another, the width of the upper surface 25 of the fixture 13 on the vertical surface of the casing, and the width of the upper surface 33 of the fixture 15 on the vertical frame The size of the frame and the distance between the vertical frame 3a and the vertical surface 6a can be easily coped with.
As shown in FIG. 1 (b), a gap d is formed between the tip of the sloped portion 13b of the vertical frame side fixture 13 of the housing and the sloped portion 15c of the vertical frame side fixture 15, Is disposed at the corner portion 17a of the vertical connection member 17, the lower surface 19 of the vertical connection material 17 and the upper surface 25 of the vertical surface side fixing tool 13 of the housing, the other lower surface 21 and the upper surface 33 of the vertical frame side fixing material 15. Can be firmly attached.
The casing vertical surface side fixture 13 is fixed to the casing vertical surface 6 a by the anchor screw 27 and is adhesively fixed to the vertical frame side fixture 15 via the vertical connection member 17, so the casing vertical surface 6 a Even if it gets wet, etc., construction is possible.

Similarly, as shown in FIG. 2, in the upper fixing portion 9 as well, the upper connecting member (connecting member) 39 is used as the upper surface side fixing tool (rod side fixing tool) 35 and the upper frame side fixing tool (frame side fixing tool) The housing upper surface 6b and the upper frame (frame) 3b can be adhesively fixed only by mounting the adhesive 37 between the members 37 and 37.
Further, the upper connecting member 39 is, by its own weight, between the upper surface 41 of the housing upper surface side fixing tool 35 and one lower surface 19 of the upper connecting material 39 and between the upper surface 43 of the upper frame fixing tool 37 and the upper connecting material 39. Since the space between the lower surface 21 and the other lower surface 21 is pressed through the adhesive 23, the adhesive strength can be enhanced.
The upper connecting member 39 is also changed by changing the width L1 of the lower surface 19 of one and the width L2 of the lower surface 21 of another, the width of the upper surface 41 of the fixing device 35 on the upper surface, and the width of the upper surface 43 of the fixing device 37 on the upper frame. The size of the frame, the distance between the upper frame 3b and the upper surface 6b of the frame, and the like can be easily coped with.
The casing upper surface side fixing tool 35 is fixed to the casing upper surface 6 b by the anchor screw 27 and is adhesively fixed to the upper frame side fixing fixture 37 via the upper connecting member 39, so the casing upper surface 6 b gets wet by rain or the like. It can be constructed even if

As shown in FIG. 3, in the lower fixing portion 11, the connecting plate 59 of the lower frame side fixing member (frame side fixing member) 47 is rotatable and vertically movable about the vertical axis, as shown in FIG. 5. The lower frame side is fixed by adjusting the fixing member 63 to an optimal position such as fixing the fixing member 63 at a position orthogonal to the inclination direction according to the construction conditions such as the housing lower surface 6c is inclined (inclination angle T) The fixture 47 can be adhesively fixed to the housing lower surface side fixing tool (the housing side fixing tool) 49. In this case, as shown in FIG. 5, the main body 61 of the lower housing fixture 49 is provided along the inclination of the lower housing 6c and the other surface 65b of the lower connecting member 65 is also bonded and fixed along the inclination of the lower housing 6c. Do.

Since the lower surface fixing member 49 of the casing has a separate lower connecting member 65, the lower connecting member 65 is arbitrarily changed or shifted depending on the construction conditions, and the connecting plate is at the optimum position. It can be adhesively fixed to the vertical wall 59 b of 59.
The lower frame side fixing tool 47 is provided with a shaft member 57, and the lower frame side fixing tool 47 and the housing lower surface side fixing tool 49 are firmly adhered while receiving the weight of the frame 3 and the shoji 5 (sash) by the shaft member 57 It can be fixed.
As shown in FIG. 3 (b), since the lower surface side fixing tool 49 has the load receiving surface 70 in the expected direction, the wind pressure is applied to the frame 3 in the state of being filled with mortar as shown in FIG. When applied, it is possible to prevent the frame 3 from being displaced or detached from the housing 6 by receiving the force in the expected direction.
Similarly, the frame lower surface side fixing tool 49 has a load receiving surface 68 in the in-plane direction, and therefore, in a state in which the mortar is filled as shown in FIG. Can be prevented from being displaced or detached from the housing 6 by receiving an in-plane force.
The lower surface side fixing tool 49 is fixed to the lower surface 6c by the anchor screw 27 and adhesively fixed to the lower frame fixing member 47 via the connection plate 59, so that the lower surface 6c of the housing is wet by rain or the like It can also be constructed.
