Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a vault roof having a truncated cylindrical shape (cylindrical shape), an arch shape, a dome shape, etc., and a supporting device thereof.

[Conventional technology]

When constructing this type of voord roof, it is possible to construct it by using curved plates that match the shape, but the processing cost is high, and it is usually impossible to do so with glass plates or the like. This problem is even more serious in the case of large structures.

Therefore, it is necessary to use a flat plate, but the support frame of the flat surface plate also needs to be bent into a polygonal shape. In other words, in the past, a large number of unit support frames matching the length of the surface plate were prepared, and these unit support frames were attached to the strength members of the structure so as to connect in a polygonal shape, and the area surrounded by each unit support frame was It was fitted into the surface plate and supported.

[Problem that the invention seeks to solve]

Generally, it is difficult to create a completely watertight structure between the support frame and the surface plate. Therefore, even in the conventional example, water leakage from the seal portion can be prevented by, for example, a gutter formed in the support frame.
Needs to be drained. However, in the conventional example, since the gutter is interrupted along the curved surface direction together with the support frame, a large number of man-hours are required to seal the connecting portion. Furthermore, it takes a considerable amount of effort to attach and position the separate support frames to the strength member.

SUMMARY OF THE INVENTION Accordingly, the main object of the present invention is to provide a vault roof and its support device that significantly reduces the number of construction steps and has excellent watertightness.

[Effect]

In the present invention, a planar surface plate is supported by continuous vertical and horizontal support frames 1 and 2. Since the surface plate 3 is flat, at least the vertical support frame 1 is provided with a receiving member 10 bent into a downward polygonal shape.

On the other hand, water leakage between the surface plate 3 and its support frames 1 and 2 is unavoidable. Therefore, drain grooves 15 and 65 are formed in the receiving members 10 and 60 of the support frames 1 and 2. However, since the vertical support frame 1 is formed from an extruded aluminum alloy material due to its complicated shape, it cannot be bent as is. Therefore, by making cuts Cu and Cd in the receiving material 10 in advance as shown in FIG. 4 and bending it as shown in FIG. 5, the substrate portion 11 can be bent while maintaining continuity. Further, by filling the cut Cu portion with a sealing material, the watertightness of the drain groove 15 or the auxiliary gutter portion 16 formed on the water side of the receiving member of the horizontal support frame can be easily maintained. The holding member 20 can also be bent by making a cut C in the same manner as shown in FIG.

In this way, it is possible to construct a support device using an inexpensive planar surface plate while maintaining watertightness and being freed from the complicated continuous work of unit support frames.

[Specific examples of the invention]

The present invention will be explained below using specific examples shown in the drawings.

This example is an example of a cut-off cylindrical vault roof as shown in Figure 2, and the first vault X moves and the second vault
It can be coated on Vault Y. In both vaults X and Y, there is a vertical support frame 1 which is approximately arc-shaped (actually a polygon as described later), a horizontal support frame 2 which is arranged horizontally, and which are surrounded by support frames 1 and 2. The main components include a surface plate 3 made of a glass plate or the like held by the frame, an arc-shaped main steel frame 4 holding each of the support frames 1 and 2, and a horizontally arranged rim steel frame 5.

The vertical support frame 1 supports the lower surface of the surface plate 3, and includes a support member 10 that is bent downward into a polygonal shape (the manner of this bending will be described later), and a support member 10 that is located above the support member 10 and extends along its longitudinal direction. Pressing material 2 that presses down the top surface of face plate 3
Consists of 0.

The receiving member 10 is provided with a substrate portion 11 and a lip groove portion 12a on the upper portion thereof, and is provided in a protruding manner at the center portion in the width direction thereof.
The mounting portion 12 of the presser member 20 and the substrate portion 11
Support parts 13, 13 protrude from both sides in the width direction, have seal holding parts 13a, 13a on the upper part, and support the surface plates 3, 3 disposed on both sides of the receiving member 10, respectively, and the base plate part 11. It is provided with rising portions 14, 14 formed on both sides in the width direction, that is, on the outer side of the supporting portions 13, 13. As a result, the drain groove 1 is separated between the mounting portion 12 and the support portion 13.
5. Between the support part 13 and the rising part 14 is an auxiliary gutter part 16. Furthermore, a fixed portion 17 having a lip groove portion 17a is formed below the center of the substrate portion 11 in the width direction.

On the other hand, the presser member 20 extends parallel to the connecting portion 21 downward from both sides of the connecting portion 21 and connects to the mounting portion 12.
A pair of leg parts 22, 22 connected to the connecting part 2
It is provided with outward L-shaped outer plate parts 23, 23 which are arranged above both sides of 1. Reference numeral 24 denotes a main body portion, which refers to the surface side portion of the outer plate portions 23, 23.

The foot parts 22, 22 of this presser member 20 are brought into contact with the lip groove-shaped part 12a of the attachment part 12, and the lower part inserted in advance between the foot parts 22, 22 is locked to the lip part. Fixed body 3 having an outward locking part
0 is connected to the receiving member 10 by pulling the fixing screw 31 into which the connecting portion 21 is inserted toward the presser member 20 side.

Further, the glass surface plate 3 is supported by the support portion 13 via a packing 32 on its lower surface, and is pressed down by the outer plate portion 23 via a sealing material 33 on its upper surface. 34 is a caulking receiving material for backing up the sealing material 33. Further, 35 is a sealing material that prevents water from leaking from the fixing screw 31 portion.

On the other hand, the main steel frame 4, which serves as a strength material for the structure, is bent into an arc shape, and brackets 36 are provided protruding from the upper surface at key points in the longitudinal direction. 37a into the rip groove 1
A fixing bolt 37 housed in the inner frame 7a is disposed and tightened with a nut 38, thereby fixing the receiving member 10, in other words, the entire vertical support frame 1 to the main steel frame 4. The head 37a has a substantially rectangular shape, and is engaged in the lip groove 17a by aligning its long axis with the opening of the lip groove 17a and then rotating it 90 degrees. Said long hole 36
Since the main steel frame 4 has a circular arc shape and the support member 10 has a polygonal shape, a is formed for position adjustment in the height direction. Numeral 39 is a lock pin which is fixed to prevent the receiving member 10 from moving in the longitudinal direction and in the vertical direction. The bracket 36' is used at the bent portion of the receiving member 10 and has a shape as shown.

A frame steel frame 5 serving as a reinforcing member is disposed horizontally orthogonally to the main steel frame 4 and straddles the main steel frame 4. In this straddling installation, connect the connecting brackets 5 from both sides of the main steel frame 4.
', 5' are welded together, and the furring steel frame 5 is fitted from the outside to these, and fixed with bolts 40.

A lateral support frame 2 is supported by a furring steel frame 5. The horizontal support frame 2 has basically the same structure as the vertical support frame 1, except that it is not polygonal like the vertical support frame 1, and the dimensions are slightly different, so only an outline will be given here.

That is, the horizontal support frame 2 has a receiving member 60 and a pressing member 70. The receiving member 60 has a base plate portion 61, a lip groove-shaped attachment portion 62, a support portion 63 for supporting the gas 3 via a seal, a rising portion 64, and a drainage groove 65 and an auxiliary gutter portion 66 are formed. . Further, a fixed portion 67 having a lip groove portion 67a is also formed.

The presser member 70 includes a connecting portion 71, foot portions 72, 72,
The outer plate parts 73, 73 and the surface part thereof are the main body part 74.
Configure. This presser body 70 is connected to the receiving member 60 by a fixed body 30 and a fixing screw 31. 82 is a packing, 83 and 85 are sealing materials, 84 is a caulking receiving material, and 84' is a setting block for the end surface of the surface plate 3. Further, as shown in FIG. 1A, the surface of the outer plate portion 73 is inclined at an inclination angle θ, usually 3 to 5 degrees, particularly 4 degrees, with respect to the tangential plane.

Similar to the vertical support frame 1, the horizontal support frame 2 has a bracket 86 having a long hole 86a in the frame steel frame 5.
is fixed by a bolt 87 and a nut 88 having a head 87a.

By the way, in the present invention, considering that the surface plate 3 is planar, the receiving member 10 has a polygonal shape along the arc of the roof. However, receiving material 10
is made of extruded aluminum alloy, for example.
Moreover, since it has a complicated shape, such as forming a gutter, it cannot be bent along the arc. Therefore, as shown slightly on the right side of FIG. 4 or FIG. 1A, the upper edges of the portions of the receiving member 10 that protrude upward from the base plate 11, that is, the mounting portion 12, the supporting portion 13, and the rising portion 14, A cut Cu is made from above to the top of the substrate portion 11, and an inverted V-shaped cut Cd is made in advance in the fixed portion 17 below the substrate portion 11. After that, as shown in Figure 5, the cuts Cu, Cd
By bending at a certain point, it is possible to easily bend the substrate portion 11 and to obtain a substrate portion 11 that is at least continuous.
As it bends, the upper cut Cu opens into a V-shape, but
By filling there with a sealing material (not shown), it is easy to maintain continuous watertightness of the gutter.

On the other hand, the presser member 20 is also bent in the same manner and has a polygonal shape. That is, as shown in FIG. 6, an inverted V-shaped cut C is made from the lower edge of the leg part 22 through the connecting part 21 to the main body part 24, and the leg part 24 is bent. In addition, when bending, make a slit-like cut from the lower edge of the foot part 22 to the bottom surface of the joint part 21 in an inverted V shape, and from the outer plate part 23 to the top surface of the joint part 21. It's okay. In short, the present invention is configured as long as the cut is formed from the foot portion 22 to the main body portion 24 consisting of the connecting portion 21 and the outer plate portion 23.

Further, the horizontal support frame 2 is installed to straddle between the polygonal bent corners of the vertical support frame 1. In the vertical support frame 1, rainwater that enters from the sealing material 33 is drained into the drainage groove 15.
However, even in the horizontal support frame 2,
There is rainwater that enters from the sealing material 83 portion and drips into the drain 65. In order to drain this rainwater, as clearly shown in FIG. It extends to near the support part 13. As a result, rainwater transmitted through the drainage ditch 65 flows from its end to the auxiliary gutter section 16.
The water falls to the ground and is drained to the ground. Note that the dew condensation water generated on the surface material 3 is received by the auxiliary gutter 66 and then drained by the auxiliary gutter 16 in the same manner as described above.

It should be noted that the present invention is applicable not only to the vault roof of the above example but also to a crossed vault or a dome roof D as shown in FIG. 8.

〔Effect of the invention〕

As described above, according to the present invention, it is economical because a flat plate-like surface plate is used, and in forming the vertical support frame, at least the base plate is connected by bending through the notches. Therefore, watertightness of the gutter can be ensured by simply placing a sealant in the notch.Compared to connecting unit support frames, the watertightness is higher and the number of construction steps is significantly reduced. Benefits such as:
