Description

[Detailed Description of the Invention] The present invention relates to a lower front girder in a building, such as a sunroom.

The lower front girder in buildings such as sunrooms is attached to the front pillar with fastening members such as connecting fittings, so the fastening members protrude from the upper surface of the lower front girder, making it difficult to connect glass window units or sliding window units or other fitting units. When installing, the protruding fixing member gets in the way,
Not only does the installation work of the fittings unit become troublesome, but
Even if a sealing material is interposed between the lower front girder and the lower frame of the fitting unit in a building, it is not possible to completely prevent rainwater from infiltrating towards the indoor side; It was unavoidable that rainwater, etc. would seep into the room due to capillary action.

The present invention was devised in view of the above-mentioned circumstances, and it is an object of the present invention to provide a lower front girder for a building that is extremely easy to install a fittings unit and that can prevent rainwater etc. from entering the room. The purpose is to

It is attached by contacting and resting on the fitting unit abutting surfaces and fitting unit mounting surfaces located on both sides of the grooves 2c, 6c, and 7c, and each frame 70, 71 in the sliding window unit F. ,72,7
As shown in Figs. 3 and 4, the outer periphery of 3 is marked with
Seal material mounting grooves 70b, 71b, 72b, 73b
are formed continuously around four times, and each sealing material mounting groove 70
Seal materials 77 are successively attached to b, 71b, 72b, and 73b, and each seal material 77 is attached to the second
It is press-fitted to the peripheral wall of the opening formed by the front frame portion 8 ₂ to maintain airtightness and watertightness.

Note that 78 (see FIG. 4) is a presser piece fitted from the outside to the bent piece 10b of the intermediate column 10;
Seal material 7 attached to both end sides of the presser piece 78
9 and 79 are crimped to the outer wall 43c of the vertical frame 43 in the glass window unit D and the outer wall 72c of the vertical frame 72 in the sliding window unit F, respectively.

As is clear from the above, the glass window unit D
The lower frame 40 in the sliding window unit F and the lower frame ₇₁ in the sliding window unit F are formed on the upper wall 7a of the lower front spar 7 in the front frame part 8 constituting the first front frame part ₈₁ and the second front frame part 82. When the fitting unit is placed on the fitting unit placement surface 7g located on both sides of the groove 7c, rainwater, etc. that enters from between the fitting unit placement surface 7g on the outdoor side and the lower frame 40, 71 is removed. , it flows down into the groove 7c and does not reach the fitting unit mounting surface 7g on the indoor side, so rainwater etc. does not flow into the room due to capillary phenomenon, and the lower front of the front frame 8 Since a groove 7c is formed in the upper wall 7a of the girder 7, the fixing member that connects the front frame portion 8 to the front column 2 and the intermediate column 10 is housed in the groove 7c. As a result, it does not protrude above the lower front girder 7, and it can be easily installed without getting in the way when installing fittings units such as the glass window unit D or the sliding window unit F to the front frame part 8. be.

Incidentally, rainwater etc. that have flowed down into the groove 7c are drained through a drainage hole 7h formed in the groove 7c (see Fig. 3).
The water falls into the lower front spar 7 and is drained through a drainage hole 7i (see FIG. 3) formed in the outer wall 7'b.

As mentioned above, the lower front girder in the building according to the present invention is made of a long material having a predetermined cross-sectional shape,
A concave groove 7c is formed along the longitudinal direction of the upper surface and has a size capable of accommodating the fixing member, and
Since fitting unit mounting surfaces 7g, 7g are formed along the longitudinal direction on both sides of the groove 7c, the fixing member for attaching the lower front spar 7 to the front pillar 2, etc. is accommodated in the groove 7c. Therefore, it does not get in the way when the fitting unit is installed, and the lower end of the fitting unit is placed on the fitting unit mounting surfaces 7g, 7g formed on both sides of the groove 7c in the longitudinal direction. The fittings are placed stably, and rainwater, etc. that has entered between the fitting unit placement surface 7g on the outdoor side and the lower end of the fitting unit flows down into the groove 7c and does not reach the fitting unit placement surface 7g on the indoor side. This means that rainwater and the like will not flow into the room due to capillary action.
