Description

[Detailed Description of the Invention] The present invention relates to a girder profile used as a girder for constructing metal balconies, verandas, etc.

For metal balconies, balconies, etc., where girders are connected in a rectangular shape via pillars and decking material is installed inside each girder, joists are installed between opposing girders, and decking material is installed on top of the joists. is normal.

However, when the floor surface (decking surface) of a balcony or veranda becomes wide, the decking material cannot be supported by the joists alone, and it is necessary to install large pullers.

In other words, it is necessary to adopt a structure in which a joist is installed between one of the opposing girders, a joist is installed between the other opposing girder, and the decking material is attached on top of the joist.

However, with this configuration, the shapes of one of the opposing girders and the other opposing girder will be different. In other words, one girder receives the bulking and the other girder receives the joist, resulting in both girders having different shapes. For this reason, two girder shapes with different shapes were used.
Different types of processing must be performed, and processing and management of mold materials become troublesome.

In order to deal with these drawbacks, conventional girder shapes have been used for balconies, verandas, etc. in which the girder and the joist are attached, and the girder that receives the girder and the girder that receives the joist are integrally formed. (See drawing 6). However, this integrally molded girder shape material is produced by extrusion molding, but because it is a large shape material, the yield of the product is low and the shape becomes very unstable.

Thus, the present invention was devised to address these conventional problems, and its purpose is to:
To provide a girder mold material that improves product yield by extrusion molding the girder mold material into two types: a girder body and a girder attachment, and which can provide the same effect as a type 1 girder mold material when used. It is in.

The present invention will be explained below based on embodiments shown in the drawings.

Fig. 1 and Fig. 2 are a plan view and a front view showing a balcony using a girder profile according to the present invention, in which a plurality of one side supports 1 and a plurality of other side supports 2 are arranged in parallel and adjacent to each other. One side support 1...One side girder 3 between
... is horizontally fixed, and the other side girder 4 is fixed horizontally between the adjacent other side supports 2..., and both side girders 5 and 5 are horizontally installed between the supports 1 and 2 on both sides of the end. Then, a large joist 6 is installed across the one side girder 3 and the other side girder 4, and a joist 7 is installed so as to be in contact with the large joist 6 between the girders 5 and 5 on both sides, and on top of the joist 7. Deck material 8 is attached. In addition, in Figure 1, Kasagi 10
It is explained with the .

Further, the reference numeral 9 in FIG. 1 indicates a staircase, the reference numeral 10 in FIG. 2 indicates a cap, and the reference numeral 11 indicates a lattice.

Figures 3 and 4 are cross-sectional views taken along line A-A in Figure 1, and B
-B sectional view, one side girder 3 receiving the large pull 6
As shown in FIG. 3, the girder main body 25 has a U-shaped cross section with an inward opening 24 from the outer vertical wall 20, the upper horizontal wall 22, and the lower horizontal wall 23, and the lower horizontal wall of the girder main body 25. Fixed part 4 provided in 23
It is formed of two types of shapes, each consisting of a girder attachment 41 that is attached to 0.

At the tip of the lower horizontal wall 23 of the girder body 25, an upwardly opened concave groove 29 is formed by a lip groove piece 30 having a lip that serves as a support surface for the large support 26, and is adjacent to the large support 26 and faces each other. Hook-shaped locking pieces 42, 42 are arranged to form the fixing portion 40.

Furthermore, the girder attachment 41 is connected to the inner vertical wall 2.
A concave groove 32 is formed from the lip groove piece 33 and the tip of the base on which the lip of the joist receiver 27, which serves as the support surface for the joist 7, is formed at the tip of the base body constituting the joist 7. The attachment part 44 is bifurcated, and hook-shaped engagement pieces 43, 43 are arranged opposite to the lower end of the base and the lower end of the hanging piece of the attachment part 44, and the engagement pieces 43, 43 are used as locking pieces. 42,42
It's locked. In addition, in the girder profile according to the present invention, the upper horizontal wall 22, the outer vertical wall 20, the lower horizontal wall 23 of the girder body 25, and the inner vertical wall 21 of the girder attachment 41 form a groove portion 34 that opens upward.

Further, the head 35a of the bolt 35 is provided in the concave groove 29.
are fitted from the longitudinal direction, and the large pull 6 is brought into contact with the upper surface 30a of the lip groove piece 30 so that the bolt 35 penetrates, and the nut 36 is tightened on the bolt 35 to tighten the large pull 6 to the large support 26. It is attached and fixed.

On the other hand, as shown in FIG. 4, the both side girders 5 that receive the joists 7 have the same shape as the one side girder 3 that receives the overhang 6, and the heads 37a of the bolts 37 are inserted into the concave grooves 32 of the joist receivers 27. The bolts 37 are fitted from the longitudinal direction, and the joists 7 come into contact with the upper surface 33a of the lip groove piece 33 so that the bolts 37 pass through the flange 7a of the joists 7, and the nuts 38 are tightened on the bolts 37 to remove the joists 7.
is fastened and fixed to the joist support 27.

Further, a groove 39 is formed in the upper wall 6a of the large drawer 6 in the longitudinal direction, and a bolt 50 fitted in the groove 39 is tightened with a nut 51 to the flange 7a of the joist 7 to tighten the joist 7. In addition to being tightened and fixed to the girder 6, a decking material 8 is attached on top of the joist 7, and the end of the decking material 8 is exposed to the inside of the girder shape through the inward opening 24 of the girder shape.

Note that FIG. 5 is a schematic diagram showing the girder shape material according to the present invention, and the assembly of this girder shape material is performed by the girder body 25.
The hooking piece 4 of the attachment part 44 of the girder attachment 41 is attached to the hook-shaped locking pieces 42, 42 of the fixing part 40 of
Fit and install 3 and 43. This attachment can be done in a so-called ridge type, making it extremely easy to attach.

Further, the upper surface 44a of the mounting portion 44 of the girder attachment 41 is flush with the upper surface of the large support 26,
When the large puller 6 is placed on the large support 26, it will also be placed on the upper surface 44a of the mounting portion 44 of the girder attachment 41, and as the bolt 35 is tightened,
The mounting portion 44 of the girder attachment 41 is held between the lower surface 6b of the large drawer 6 and the lower wall 23 of the girder body 25, and the girder attachment 41 is firmly fixed to the girder body 25. Therefore, girder attachment 4
1 and the girder main body 25 have integrity, and the girder attachment 41 does not wobble even though it is a split member.

Thus, the present invention has the above-mentioned configuration, and since the girder mold material according to the present invention is formed of two types, the girder body and the girder attachment, the product yield is good when manufactured by extrusion molding, and the girder body and girder attachment Attachments can be installed easily and firmly.

Therefore, it is possible to provide the market with a girder shape material having the same effect as the integrated girder shape material, which can be used both as a girder for receiving bulk pulling and as a girder for receiving joists, as in the past, with a high yield.

Furthermore, since the upper surface of the mounting part of the girder attachment and the upper surface of the girder attachment are made flush, the lower surface of the girder bolt fixed to the girder body with bolts comes into contact with the upper surface of the mounting part, and the mounting part is placed between the girder attachment and the girder attachment. By clamping, the spar attachment is securely and firmly fixed to the spar body.
