Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for constructing a frame of a relatively long arch-shaped structure used for outdoor walkways, pedestrian bridges, sunrooms, light fixtures, greenhouses, carports, etc., and a method for constructing arch-shaped structures. Regarding.

Traditionally, this type of structure consists of an arched vertical frame made of extruded aluminum or steel, connected at the construction site by two frames made of the same material as the vertical frame, and then constructed as a frame. It was assembled by pasting a face material on it and then sealing it to protect it from wind and rain.

However, most of the above work is carried out on-site, and since the level of workmanship of the arch-shaped vertical frame is relatively poor, it requires a great deal of skill to assemble each member on-site using this method. Ta.

In addition, a completed structural unit is made in a factory using vertical frames, horizontal frames, and facing materials, and a long structure is constructed by connecting the oppositely abutting ends of the vertical frames of the units on site. There is another method, but it has the disadvantage that the vertical frame is doubled at the connection part, making it uneconomical in terms of materials.

The present invention has been made in consideration of the drawbacks of the conventional methods described above, and is a set assembly of an arch-shaped structure in which all vertical frames processed into an arch-shape, which had problems in on-site construction, are assembled in a factory. The present invention relates to a method of constructing a (skeleton) and a method of constructing an arch-like structure using the same.

In other words, the first invention is a vertical frame that has problems in on-site construction.
or more in parallel and connect each vertical frame with a plurality of horizontal frames to create a set in the factory, and at the site, the sets are placed at predetermined intervals equal to the length of the horizontal frames. The object of the present invention is to provide an advanced method of constructing a frame in which the sets are arranged in a straight line and the sets are connected by horizontal frames to constitute the frame of a long arch-like structure.

Further, although arch-shaped structures usually have a panel attached to the frame, the panel may be attached when the frame formed by the present invention is completed at the construction site, but this is provided as a second invention. If the following method is used, the on-site construction will be simple and effective when installing the facing material.

In other words, in the second invention, the facing material is also attached in the factory to the set assembly created in the factory in the first invention, and the set assembly with the facing material attached is delivered at a predetermined interval equal to the length of the horizontal frame at the construction site. This is a method of constructing an arch-like structure in which the sets are arranged in a straight line, and the sets are connected with face members and a plurality of horizontal frames.

Hereinafter, the second invention will be described in detail with reference to drawings showing embodiments.

Figure 1 shows arch structure set group 1 arranged in a straight line.
. (uses three vertical frames) are arranged in parallel, each of the vertical frames is connected by a plurality of horizontal frames 3, and a facing material 4 is attached to this in an arch shape to form a set. do.

The interval W between the mutually opposing vertical frames 2 and 2 of sets 1 and 1' is set equal to the length of the horizontal frame 2, and this spatial interval W
are connected using a horizontal frame 3 and a panel 4 to form a long arch-shaped structure.

The second invention has been described in detail above, but since the material, color, etc. of the face material differs depending on the design specifications, in order to mass produce a single model of a set, only the set is manufactured at the factory, and it is changed at the site. A desired surface material may be attached.

The first invention is adapted to such a case.

To explain each constituent member of the structure in FIG. 1 in more detail with reference to FIGS. 2 and 3, 2 is a vertical frame made of extruded material such as aluminum and curved into an arch shape, and a hollow thin wall portion 2a
A panel mounting portion 2b is formed on the inside and on the outside.

Reference numeral 5 denotes an arch-shaped batten to be attached to the outside of the vertical frame 2, and a groove 5a for a heat insulating backing is provided on the inside, and a screw for fixing the batten 8 to the vertical frame 2 through a heat insulating backing material 11 is provided in the groove. Drill a screw hole 5b.

Reference numeral 6 denotes an arch-shaped condensation tray, a part of which is formed in a ■-shaped cross section, and is attached to the face material attaching portion 2b of the vertical frame 2 via a sheet 12 made of synthetic rubber or the like.

Reference numeral 4 designates a flexible synthetic phase trapping surface material which is attached onto the condensation catcher 6 via a setting material 13 such as synthetic rubber.

The face material 4 is attached to the face material attachment portion 2b of the vertical frame 2 using screws and pins.

Note that 14 is a heat insulating material provided inside the batten 2.

In particular, the frame-related members shown in FIG. 3 are also made of members having the same cross-section as the vertical frame-related members shown in FIG. 2 to improve compatibility.

In the figure, 3 is a horizontal frame, 2'a is a hollow thin wall part, 2'b is a face material attachment part, 5' is a batten, 5'a is a heat insulating backing groove,
5'b is the screw hole for attaching the batten to the horizontal frame, 11'
is a heat insulating backing material, 6' is a condensation catcher, 12' is a setting material for seams 1-113', 14' is a heat insulating backing material, 4 is a face plate and is attached to the face plate mounting part 2'b with screws or pins. .

The above-mentioned vertical frame, horizontal frame, battens, and condensation pan are each integrally formed of extruded materials such as aluminum.

A foundation fixing bracket 7 made of a thick plate of aluminum or the like is welded to the lower end of the vertical frame 2 and is fixed to the concrete foundation 9 via anchors 8.

Next, the assembly of this structure will be explained with reference to FIGS. 4 to 8.

When assembling the set sets 1 and 1' in the factory, two or more vertical frames 2 and a plurality of horizontal frames are roughly assembled using welding or screws, etc., and the face material 4 is attached to the set set. Attach via screws and pins.

In this case, it is convenient to attach the face material to the vertical frame using pins and to the horizontal frame using screws.

A heat insulating backing material 11.1 in which the heads of the above pins and screws are fitted into the backing grooves 5a and 5'a of each batten 5 and 5'.
1' is pressed through a batten to insulate it.

In this case, the battens and pins to be attached to the vertical frame at the end of the set are left unattached, or the battens are temporarily fixed by inserting pins.

A back-up material is applied to the gap between each of the battens and the face material used for the parts other than the vertical frame at the end configured as described above, and then a sealing material is filled.

The length of the set 1 or 1' to which the face material is attached is designed to be suitable for truck transportation, etc.

Furthermore, the end faces 15, 15 of the vertical frames 2, 2, which correspond to both ends of the center assemblies 1, 1', are cut out [Figs. 4 and 5] and the fittings 10 made of aluminum casting or the like are inserted into the vertical frames. Metal fittings 1
Part 0a is fixed with screw 16.

The cellars I and set 1 or 1' transported to the installation site are arranged in a straight line at intervals equal to the length of the horizontal frame.

Notches 17 (Fig. 6) are provided in advance at the bottom of both ends of the horizontal frame 3 to connect the sets, and the horizontal frame 2 is fitted from above into the portions 10b and 10b of the joint fittings 10, 10 that protrude oppositely, Fix with screw 18.

Next, the face material 4 is attached with screws, pins, etc. in the same manner as in the set assembly process, and after the battens 5' are attached, the gap is filled with a sealing material.

Incidentally, when filling the space between the vertical frame 2 and the horizontal frame 3 with the sealing material 19, the recess 10C of the joint fitting 10 serves as a backup.

. The vertical and horizontal frames of the set assembly were roughly assembled by welding or screws without using fittings, but the set assembly was assembled using fittings in the factory as well as on-site assembly. Good too.

The present invention is constructed as described above, and most of the work is carried out in a well-equipped and well-managed factory, resulting in good accuracy, and the on-site work is simple and requires no skill.

Since the vertical frames facing the joint are not overlapped, there is no waste of material.

Furthermore, as shown in the example, the batten is insulated by a backing material, which has a great heat insulation and dew-proofing effect, and the vertical and horizontal battens, frames, and condensation ribs are compatible because they are made of the same cross-sectional material. It has many characteristics such as excellent sex.
