DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arched eaves-supported frame provided in an assembly structure such as a shelter, an approach, and a canopy.

[0002]

2. Description of the Related Art For example, some shelters for underground passages are provided with arched eaves. As a frame of the arched eaves, an arched front and rear frame portion arranged at intervals, and a left and right side frame portion connecting the left end portion and the right end portion of the front and rear frame portion are provided. Some are provided with struts extending downward from both left and right ends (FIG. 2).
reference).

Conventionally, such a frame with a pillar of an arched eave has been manufactured by welding a front frame member, left and right frame members, and a rear frame and a pillar member, all of which are made of stainless steel pipe, at a factory. Was formed.

[0004]

However, since the above-mentioned conventional frame with a support of an arched eave is very large and bulky, it is difficult to transport it to a construction site, and it is possible to transport it once by a transport vehicle or the like. The number of hits was small and the transportation efficiency was poor. In addition, since the weight becomes considerably large, a crane and a UNIC are required for transportation and construction, and the construction cost is accordingly high.

SUMMARY OF THE INVENTION An object of the present invention is to provide an arched eaves-supported frame which can be easily and efficiently transported to a construction site and does not require a crane or a unic at the time of construction. It is in.

[0006]

According to the present invention, an arched eaves-supported frame according to the present invention connects arched front and rear frames arranged at an interval with left and right ends of the front and rear frames. In a left-right frame portion and a post-supported frame having an arch-shaped eave comprising a post extending downward from the left and right ends of the rear frame portion, the frame is divided into right and left halves, and the divided front and rear frame portions have ends joined together. The left and right frames are joined to form a left and right frame half, and the left and right frame half bars are connected to each other.

As described above, the frame with the column of the arch-shaped eaves is divided into left and right halves, and the crosspiece is transferred between the ends of the divided front and rear frame portions to form the left and right frame halves. If the left and right frame halves are connected to each other, they may be transported to the construction site in a state before the left and right frame halves are connected, that is, in a compact state in which the left and right frame halves are separated. Then, at the construction site, the crosspieces of both frame halves may be connected.

As means for connecting the crosspieces of the left and right frame halves, bolt connection is preferable in terms of workability.
Riveting or field welding may be used.

[0009]

Next, an embodiment of the present invention will be described with reference to the drawings.

In this specification, the front means the front side of the drawing sheet of FIG. 3, the rear means the same back side, and the right and left mean the left and right of FIG.

FIG. 2 shows an underpass entrance shelter to which an arched eaves-supported frame according to the present invention is applied. The shelter (1) is a concrete base provided on the left and right side edges and the rear edge of the underpass entrance.
(2) Dome shelter body
(3) and an arched eave (4) provided at the front end of the shelter body (3).

The arched eaves (4) are arched front and rear frame portions (11) arranged at intervals, and left and right frame portions (4) connecting left and right ends of the front and rear frame portions (11). 12) and a frame (10) with a support, which comprises a support (13) extending downward from the left and right ends of the rear frame (11), and an eaves panel (14) fitted to the frame (10).
(See FIG. 2).

The supporting frame (10) is divided into left and right halves,
The crosspiece (15) is handed over between the ends of the divided front and rear frame portions (11) to form a left and right frame half (10A), and the left and right frame half (10A)
Are connected to each other (see FIGS. 1 and 2).

Each of the frame halves (10A) comprises a front frame / side frame member (16), a rear frame / post member (17) made of stainless steel pipe, and a steel bar (15). (See FIG. 1). The parts to be joined of these members (16, 17) and the bars (15) are welded in the factory. Note that the front frame / side frame members (1
6) is made of a stainless steel pipe smaller in diameter than the divided frame / post member (17), thereby reducing the weight. Prop
The lower end of (13) is factory-welded to the upper surface of the front end of the base plate (5) attached to the upper surface of the left and right sides of the base (2) (see FIG. 2).

As shown in FIGS. 3 and 4, the left and right frame halves
In the front end portion of the divided front and rear frame portions (11) in (10A), a cut-out annular seal receiving member (18) having a cut off upper portion is provided. Further, a positioning member (19) having a T-shaped cross section is inserted in the front end portion of the divided front and rear frame portions (11) of the left and right frame half bodies (10A). Then, the left and right frame half (1
0A) between the front end portions of the divided front and rear frame portions (11),
Sealed by the seal material (20) received by the seal receiving member (18).

The bar (15) is, as shown in FIGS.
It has an inverted L-shaped cross section, and has bolt holes (not shown) at a plurality of predetermined front and rear portions of the vertical wall portion (151). The bars (15) of the left and right frame halves (10A) are connected to each other by a plurality of sets of bolts (22) and nuts (23) through an annular spacer (21) having bolt holes. It is connected on site by tightening.

On the inner surfaces of the divided front and rear frame portions (11) and the left and right frame portions (12) of the left and right frame half bodies (10A), a stainless steel eaves panel mounting member (24) having a cross-sectional groove shape is provided. It is pre-welded at the factory (see FIGS. 3 and 4). As shown in FIG. 3, a stainless steel panel mounting member (25) having a lip-groove cross-section at the factory is located between the front ends of the divided front and rear frames (11) in the left and right frame halves (10A). Has been passed and welded. In FIG. 4, the illustration of the panel mounting member (25) is omitted for convenience.

The upper and lower eaves panels (14) are fitted on the left and right sides of the frame (10), two by two (see FIG. 3). Upper eaves panel (14)
Is made of an aluminum plate whose periphery is bent downward. The upper eaves panel (14) is screwed to mounting members (24, 25) via a connection fitting (not shown) at the site. The lower eaves panel (14) is made of an aluminum plate whose peripheral edge is bent upward. The lower eaves panel (14)
It is directly screwed to the mounting members (24, 25) at the site (see FIGS. 3 and 4). The eaves panel (14) is preferably formed of the above-described aluminum plate or other opaque material. This is because the use of the opaque eaves panel (14) hides the connecting portion between the crosspieces (15) of the left and right frame half (10A) and is good in appearance. The upper and lower two eaves panels (14) on the left side have seal receiving portions (26) extending rightward from the ends of these right edge bent portions.
(See FIG. 3). Right and left eaves panels (1
5) The space between the members is sealed by the seal material (27) received by the seal receiving portion (26) (see FIG. 3). As shown in FIG. 4, the sealing material (2) is also provided between the eaves panel (14) and the frame (10).
8) Sealed.

[0019]

According to the present invention, the arched eaves-supported frame is
As described above, the state before connecting the left and right frame halves to each other, that is, the left and right frame halves are transported to the construction site in a compact state separately, and the two frame halves are joined at the construction site. Can be linked. Therefore, according to the present invention, it is possible to easily and efficiently transport the frame with the pillars of the arched eaves to the construction site, and no crane or unic is required for the construction.
