Description

[Detailed description of the invention] The present invention is a joint structure provided between a steel column and an external wall panel, in which a joint material or a joint filler is used in the joint gap without any special processing on the steel column side. Reliable and easy installation is required.

There are various types of joint structures, but when installing the joint material or joint material, it is necessary to construct a fixing structure for the joint material or joint material on the steel column side, or Many require the use of various fixing auxiliary members or special processing means, which tends to cause troublesome problems in terms of productivity and workability.

This invention does not require any special installation work on steel columns, and the joint material or joint material itself has a fixed structure, making joint construction extremely easy and quick. It is designed to ensure secure fixation and improve the sealing effect, and its unique feature is that each end of a pair of exterior wall panels is placed facing each other with a joint gap in front of the steel column. In the case where the support is installed, a stopper having an opening/closing leg that can be locked to the steel column joint is inserted from the bottom surface into the joint gap, and a stopper having an opening and closing leg that can be locked to the steel column joint is inserted into the joint gap, and a stopper is attached to the stopper and the stopper on the front surface thereof. Hollow joint material or joint material with a gap for inserting screws that can be opened and closed freely.
The front surface is pushed in in a recessed manner, and a caulking material is filled and sealed on the recessed front surface.

The present invention will be described in detail with reference to the embodiments shown below. Figure 1 is a cross-sectional plan view of an embodiment of the joint structure according to the present invention, and Figure 2 is an exploded slope view of the joint material (or joint material). In Fig. 1, 1 is a steel column, and as an example, the steel column 1 in the figure is made of a pair of C-shaped steels 1a and la, erected in parallel with their open sides facing each other. Both C
The shaped steels 1a, 1a are connected together on their inner surfaces by connecting fittings 2 as is known, and the lower end of the steel column 1 is fastened and fixed to the foundation, which is different from conventional steel columns of this type. The same is true.

Also 1b. Reference numeral 1b denotes a bent edge on each side of the C-shaped opening, and the bent edges 1b, 1b portions facing the outer wall panels 3, 3 are joint portions 4 of the joint filler (or joint filler).

The outer wall panels 3, 3 each have one end supported on the front surface of the steel column 1 with a joint gap 3a in a facing manner, and the inner frames 5, 5 are made of wood, which is different from the conventional outer wall panel structure. is the same as

Reference numeral 6 denotes a hollow joint filler (or joint filler, hereinafter the same applies, so this will be omitted) according to the present invention, and the joint filler 6 has a structure as shown in FIG.

That is, the hollow joint material 6 has a hollow shape surrounded by the front surface 7, both side surfaces 8, 8, and the bottom surface 9, and the fastener 10 is inserted through the insertion hole 9a provided in the bottom surface 9.

As shown in the figure, the fastener 10 has a head 10a that is locked on the bottom surface 9, and opening/closing legs 10b, 10b that project in parallel from the bottom surface of the head 10a.
b.

At the lower end of 10b, there are chevron-shaped locking portions 10C and I that are locked to the bent edges 1b and lb of the joint portion 4 of the steel column 1.
OC is formed, and an insertion hole 10d for the screw 11 is formed in the head 10a.
The screw 11 is locked in the insertion hole 10d by having the screw 11, and the screw 11 has a length such that the lower end of the screw 11 is inserted between the chevron-shaped locking portions 10c, 10c of the opening/closing legs 10b, 10b. Therefore, the front surface 7 of the joint material 6 has an opening/closing gap 7a for inserting the stopper 10 and the insertion screw 11.
The outer surfaces of both side surfaces 8, 8 are provided with uneven surfaces 8a, 8a for close contact.

In the present invention, the joint material 6 having the above structure is used,
As shown in the exploded view of FIG. 2, the front surface 7 of the joint material 6 is opened through the opening/closing gap 7a, the stopper 10 is inserted through the hollow interior, and the opening/closing legs 10b, 10b are opened. This joint material 6 is inserted outside the bottom surface 9 through the insertion hole 9a.
is pushed into the joint gap 3a from the front side, and by this pushing, the opening/closing legs 10b, 10b are once retracted and closed, and are inserted into the joint part 4 of the steel column 1, and the opening/closing legs 10b.

The chevron-shaped locking portions 10C910C at each lower end of 10b are bent edges 1
b, lb protrudes outside the lower end and expands into a mountain shape due to its own elastic restoration, and is locked with the bent edges 1b, lb.

After that, the opening/closing leg 1 is inserted through the insertion hole 10d provided in the head 10a of the stopper 10 from the opening/closing gap 7a of the screw 11.
If inserted between 0b and 10b, opening/closing legs 10b and 10b
This prevents the joint material 6 from shrinking and closing, and the joint material 6 is embedded and fixed in the joint gap 3a in a filling manner as shown in the first figure.

After that, caulking material 12 is filled and coated on the front surface 7 of the joint material 6 recessed into the joint gap 3a, and the outer wall panel 3
This is because the joint construction is completed on the same surface as the surface of , 3.

According to the joint structure of the present invention, there is no need to combine a joint material fixing structure or a fixing member to the steel column 1, and the steel column 1
The bent edges 1b, 1b at the joint portion 4 and the opening/closing leg 10b of the stopper 10.

Through engagement with the chevron-shaped locking portions 10C and IOC in 10b, the joint material 6 can be fixedly buried very reliably and easily.
Due to the presence of the screw 11 inserted between the opening/closing legs 10b, 10b, the chevron-shaped locking portion 10C91 engages with the bent edges 1b, lb.
0C does not contract or close, but maintains its open/expanded posture, and the joint material 6 does not move or pull out at all, and
The bottom surface 9 of the joint material 6 is tightly fixed to the joint part 4 of the steel column 1 using the fasteners 10 and screws 11, and the caulking material 12 is further filled and coated on the front surface 7 of the joint material 6. , double sealing effect is obtained, airtightness,
Water-like properties are reliably obtained, and the sealing properties are excellent.

In addition, the joint material 6 can be easily installed by pushing the pre-assembled joint material 6 into the joint gap 3a and pushing the screw 11, and the workability is extremely good, eliminating the need for a complicated structure. It is excellent as a simple and effective joint structure.
