Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for attaching fire-resistant panels inside plate glass in a mullion in a curtain wall.

(Prior Art) In a curtain wall, plate glass is fitted into a lattice-like framework made up of mullions and horizontal bars, and fireproof panels are attached to the inside of the grid at locations other than the windows for daylighting.

Conventionally, this type of fireproof panel mounting device has a U-shaped cross section that clamps the ends of the fireproof panel, and has a mounting piece protruding from one end, as shown in Japanese Utility Model Application Publication No. 59-102814, for example. A frame member made of extruded material was used, and the mounting pieces were screwed into mullions to support the fireproof panel.

(Problem that the invention aims to solve) However, according to the building standards, the thickness of the fireproof panels does not necessarily have to be the same, and the minimum thickness depends on the area of the room that the fireproof panel faces, the equipment, the date and time of use, etc. Several types of fire-resistant panels are commonly used, varying in thickness. Therefore, with conventional fireproof panel installation equipment, it is necessary to prepare extruded frame members with different cross-sectional shapes or sizes for different thicknesses, and due to extrusion molding of the members, The drawback was that it was inevitably expensive in terms of mass production.

In view of the above-mentioned actual situation regarding curtain walls, the present invention is not only inexpensive but also easy to install fireproof panels because the frame member for attaching fireproof panels is suitable for mass production of types according to the thickness of the fireproof panels. It is an object of the present invention to provide a fireproof panel mounting device that is easy and can stably support the fireproof panel.

(Means for solving the problem) In order to achieve the above object, the present invention includes an anchor that is screwed to the side of the mullion, an incomplete frame member that is hung on the anchor and fixed to the mullion, and It consists of a complementary ridge member that is screwed to the frame member and clamps the end of the fireproof panel together with the incomplete frame member, and the anchor has an outwardly directed hooking piece at one end and an outwardly engaging piece at the other end. The incomplete frame member has leg pieces protruding from both ends to hold the anchor,
The tip of one leg piece is provided with an inward locking piece that hangs on the outward locking piece of the anchor, and the tip of the other leg piece is provided with an inward engaging part that can be hung on the outward engaging part of the anchor by pressing, The supplementary rim member has a side plate shape whose base end in the width direction can be screwed to the outer surface of the other side of the incomplete frame member, and has a side plate shape whose tip end can be screwed to press the fireproof panel against the rim opposing piece. A ridge protrusion for clamping is provided, and depending on the length of the ridge protrusion, both thin and thick fireproof panels can be supported.

(Example) The drawing shows one example, and the curtain wall is constructed by fitting plate glass G into the framework of mullions H and horizontal beams S (Fig. is fitted with fire-resistant panels Pa and Pb, but the fire-resistant panel Pa on one side of the first mullion H is 25 mm thick for 30 minutes fire resistance, and the fire-resistant panel Pb on the other side is for 1 hour fire resistance. 40mm thick ones are used (Figure 2). Both panels Pa and Pb are supported by the mullions H and the horizontal beams S by mounting devices A and A, and the mounting device A consists of an anchor 1, an incomplete frame member 2, and a complementary rim member 3. There is (3rd
figure).

Incidentally, since the attachment of the fireproof panels Pa and Pb to the horizontal beam S is the same as the attachment to the mullion H, detailed explanation thereof will be omitted.

The mullion H is formed hollow by combining a pair of left and right half members 5a and 5b having a roughly U-shaped cross section (Fig. 2), and a connecting member J of the upper and lower mullions H, H.
A pair of left and right connecting pieces 6 also have a substantially U-shaped cross section.
It consists of a and 6b. Further, the mullion H is fixed to the building projectile B by a connecting member J, and the horizontal beam S is assembled to the mullion H.

Regarding how to attach the mullion H to the building projectile B, fix the angle-shaped support fitting 7 to the building projectile B in a horizontally long manner, and place one piece of it protruding downward (Fig. 5). In this case, a pair of left and right brackets 8, 8, which are also angular in shape, are fixed vertically with bolts 9 (Fig. 2), a mullion H is sandwiched between both brackets 8, 8, and screws 10, 10 are inserted from the brackets 8, 8, respectively. It is passed through the half members 5a, 5b of the vertical H, and screwed into the half members 6a, 6b of the connecting member J and tightened.

Regarding the fireproof panel installation device A, attach the anchors 1 to the mullions H with a plurality of screws 1 at predetermined locations.
1, the incomplete frame member 2 is hung on a series of anchors 1 and 1, and the complementary rib member 3 is attached to the incomplete frame member 2 with screws 12, thereby fixing the ends of the fireproof panels Pa and Pb. Both members 2,
3 (Fig. 2, Fig. 4).

The anchor 1 has a substantially rectangular plate shape (the third
(Fig.), a through hole 1a for the screw 11 is made in the center, but a very low pedestal 1b is formed along the edge of the back surface facing the side surface of the mullion H at the outdoor end. be. In addition, at the outdoor end, the outward latch 1c is formed so as to be higher than the seat 1b by forming that part in a step-like manner, and at the indoor end, that part is formed thickly and the outer surface is shaped like a dogleg. A protruding outward engaging piece 1d is provided.

The incomplete frame member 2 has leg pieces 2b and 2c that hold the anchor 1 hanging at both ends of the base plate 20 facing the end faces of the fireproof panels Pa and Pb, and the fireproof panel along with the complementary rib member 3 is attached to the outdoor side end. A protruding edge opposing piece 2d that sandwiches Pa and Pb is provided in a protruding manner, and opposing protrusions 2k are formed at the tips of the protruding pieces 2d. Further, at the tip of the outdoor side leg piece 2b, an inward hooking piece 2e that hangs on the outward hooking piece 1c of the anchor 1 is formed, and at the tip of the indoor side leg piece 2c,
An inward engaging portion 2b having a melon-shaped cross section is formed to engage with the outward engaging portion 1d of the anchor 1. In addition, a mounting screw 1 for the complementary rib member 3 is attached to the indoor leg piece 2c.
2 screw holes of 2 m are drilled.

Both of the complementary rib members 3, 3 have slightly different cross sections, but this is a side plate shape whose base end is screwed to the indoor leg piece 2c of the incomplete frame member 2, and the incomplete frame member 2 at the tip. Along with the opposing protrusion 2k at the tip of the rim opposing piece 2d of the frame member 2, rim protrusions 3a and 3b that sandwich the fireproof panels Pa and Pb are provided in a protruding manner. In both complementary rib members 3, 3, these rib protrusions 3a, 3
Both fireproof panels with different protrusion lengths of b
Pa, Pb are also the opposing protrusions 2k and the ridge protrusions 3a, 3b.
It is designed so that it can be pressed and held between the two. In addition, a through hole 3c for a screw 12 is provided at the base end (Fig. 3).

Next, an example of the procedure for installing the fireproof panels Pa and Pb will be described. First, the anchor 1 is fixed to the mullion H using the screws 11, and the incomplete frame member 2 is attached to it. When attaching this, first attach the inward hooking piece 2 to the outward hooking piece 1c of the anchor 1.
Press the inward engaging portion 2b side while applying e. Then, the incomplete frame member 2 is elastically deformed, and the inwardly engaging portion 2b at the tip of the leg piece 2c is caught on the outwardly engaging portion 1d of the anchor 1. Note that the outward engaging portion 1
The outer side of d is a dogleg-shaped inverted slope 1e (6th
Since the upper surface of the inward locking piece 2e is a slope 2h, both leg pieces 2 are guided by the slopes 1e and 2h.
b, 2c are pressed against mullion H.

When the incomplete frame members 2 are attached in this way, a frame of the incomplete frame members 2 will be created within each frame of the mullions H, and the fireproof panels Pa, Pb will be attached to the frames.
and insert it into the rim facing piece 2d of the incomplete frame member 2.
While pressing the complementary rib member 3 against the screw 12
This fixes it to the indoor leg piece 2c.

According to the above procedure, the incomplete frame member 2 and its complementary rib member 3 sandwich the fireproof panels Pa and Pb,
Since the fireproof panels Pa and Pb are supported by the mullions H and horizontal beams S via the anchors 1, the installed state of the fireproof panels Pa and Pb is maintained.

Regarding the coupling relationship between the anchor 1 and the incomplete frame member 2, since the outward hooking piece 1c of the anchor 1 and the incomplete frame member 2 are deeply engaged, they will never come off. On the other hand, although the outward engaging part 1d and the inward engaging part 2f have a shallow engagement due to the installation procedure, the base end of the complementary ridge member 3 is integrally fixed to the outdoor leg piece 2c with the screw 12. , not only the strength of the leg piece 2c is strengthened, but also the fireproof panel Pa,
Hold down Pb, and by the reaction of the holding down, the indoor leg piece 2c
is pressed against the anchor 1, so both engaging portions 1d,
The 2f bond is also very strong and maintains a stable bonding relationship. Therefore, the incomplete frame member 2 will not be removed from the anchor 1 unless the complementary rim member 3 is removed.

The complementary rib member 3 having the long rib protruding piece 3a and the complementary rib member 3 having the short rib protruding piece 3b both have a small cross section, so they can be molded at the same time by machining multiple pieces with the same die. Since it is possible to produce a large number of pieces even if there are more types than the number of types, it is advantageous for mass production. In addition, the incomplete frame member 2 is used for both fireproof panels Pa and Pb regardless of their type. Therefore, as described above, even if a complete frame member is completed by combining the incomplete frame member 2 and the complementary rim member 3, it is advantageous in terms of cost compared to the case where the complete frame member is integrally molded. becomes.

(Effects of the invention) As explained above, the present invention consists of an anchor that is screwed to the side of the mullion, an incomplete frame member that is hooked onto the anchor and fixed to the mullion, and an incomplete frame member that is screwed to the incomplete frame member. It consists of a complementary ridge member that clamps the end of the fireproof panel together with the incomplete frame member, and the anchor is provided with an outward latching piece at one end and an outward engaging part at the other end, The incomplete frame member has legs protruding from both ends that hold the anchor, an inward hooking piece that hangs on the outward hooking piece of the anchor at the tip of one leg, and an anchor at the tip of the other leg. An inward engaging portion that can be engaged by pressing is provided on each of the outward engaging portions of the complementary rib member, and the complementary rib member has a side plate shape whose base end in the width direction can be screwed to the outer surface of the other side of the incomplete frame member. The tip is provided with a clamping ridge protrusion that presses the fireproof panel against the ridge opposing piece by screwing the tip, and therefore, according to the present invention, the anchor, the incomplete frame member, and the complementary A fireproof panel is attached to a mullion by combining it with a supplementary rim member, but by preparing several types of complementary rim members with different protruding lengths. Since it is possible to install fireproof panels of different thicknesses, it is possible to avoid the high cost of preparing complete frame members with different cross sections. In addition, the incomplete frame members can be easily attached to the mullions using anchors, and the fireproof panel is housed after the installation, making the installation process easy. As a result, the incomplete frame member is prevented from coming loose from the anchor, resulting in excellent effects such as maintaining a stable attached state of the fireproof panel.
