DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a framework for a metal fitting such as steel or stainless steel.

[0002]

2. Description of the Related Art Conventionally, in a metal fitting having a framed structure in which members such as an upper frame, a blind frame, and a lower frame are assembled as a horizontal frame with respect to an upright vertical frame, a fastening member such as a screw or the like is used. Each part is assembled using welding. As a novel idea for such an assembling, Japanese Patent Application Laid-Open No. Hei 10-205235 discloses that a vertical frame and a horizontal frame are formed by using tapered screws (immo screws) in connection holes provided in both connection members as shown in FIG. There is disclosed a technique in which a frame is called into a vertical frame side and fastened.

[0003]

However, in the present invention, the vertical frame has a blind or lower frame intrusion member protruding outside the expected surface of the vertical frame. The calling member is easily damaged. In addition, since there is nothing to receive water droplets and the like formed by dew condensation flowing down the glass channel from above the vertical frame, water droplets etc. flow directly down to the floor surface and prevent stains on the floor around the vertical frame Can not do it. In addition, regarding the fastening structure of the horizontal frame such as the blind frame to the vertical frame, the screw hole for screwing the tapered screw on the blind side and the taper screw insertion hole projecting from the expected surface of the vertical frame are fixed in advance. Had to be kept eccentric within the range. in this case,
There is no problem as long as the tapered portion at the tip of the tapered screw has the above eccentric positional relationship within a range that can be inserted into the tapered screw insertion hole due to the processing accuracy of the frame and the component parts, but the eccentric position outside the above range is not a problem. In the case of the relationship, the horizontal frame such as the blind can no longer be brought into the vertical frame side. Therefore, in order to ensure the production and mounting position of a member having such an appropriate eccentric positional relationship, the accuracy of the member processing and the hole position is required, and before assembly, it is determined whether or not the eccentric positional relationship is satisfied. It had to be confirmed and it took time. Further, since a large rotational moment acts on the member having the tapered screw insertion hole due to the attraction by the tapered screw, it is necessary to make the member itself strong and have a structure that can withstand this moment. Had a complicated structure.

In view of the above, the present invention has been made in view of the above circumstances, and further facilitates the positioning of the assembling during assembling, and simplifies the structure of the connecting member to reduce the assembling work between the members. It is an object of the present invention to provide a vertical frame and a vertical frame / horizontal frame assembling structure in a metal fitting which can be more easily performed.

[0005]

[0006]

[0007]

[0008] This eliminates the need to decenter the screw hole into which the tapered screw is screwed and the tapered screw insertion hole so as to partially overlap each other in advance. Even in the assembling work at the construction site, it is possible to extremely easily create a partially overlapped state of the screw hole and the tapered screw insertion hole afterward by adjusting the position of the block. Further, the block itself has a very simple structure, but can sufficiently withstand the rotational moment force caused by the action of the tapered screw.

For this reason, the block 130 is formed on the prospective surface 10 b of the vertical frame 10.
From the bottom wall 100c to the front and rear.

The procedure for assembling the vertical frame 10 having the above members will be described in detail. Since the conventional technology can be used as it is for the processing of the main body of the vertical frame 10 and the glass groove 100, fitting of the slit 120, the block 130 into the slit 120, and attachment of the blind positioning means 110 will be described.

First, the first to third slits 120
a, 120b, and 120c are formed by notching in the glass groove 100. In this case, each slit 120a, 120b, 1
The position and the size of the vertical frame 20c on the vertical frame 10 are determined in advance by an assembly drawing (normally,
It shall be slightly higher than the middle of the blind height when assembled to zero. ). Also, each slit 120a, 120b, 1
The width dimension of 20c is not particularly limited, but the height dimension is such that the block 130 fits loosely.

Next, the block 130 is moved from the opening of the glass groove 100 to the first to third protruding sides 130a, 130a.
b and 130c are respectively connected to the first to third slits 12
0a, 120b, and 120c.
As shown in FIG. 3A, the block 130 includes the first
The protrusion side 130a30b of the second part is the first and second slit 12

Next, the vertical frame-side mounting portion 110a of the blind positioning means 110 is screwed into the vertical frame 10 at the predetermined position.
Is fixed to the prospect surface 10b. Vertical frame mounting surface 110a
Thus, escape of the block 130 from the glass groove 100 to the outside is restricted. The screw 140 is connected to the block 130
This is used for adjusting the positioning of the slit 120 in the front-rear direction.

In such a vertical frame 10, the block 1
If the position of 30 is, for example, as shown in FIG. 3A, a spacer (not shown) is inserted into the gap between the glass groove 100 and the expected frame surface 10b, or if it is filled with putty or the like, a vertical frame is formed. It is possible to prevent the intrusion into the glass groove 100 from above, or the infiltration of rainwater that travels through the blind 30 and descends in the glass groove 100. Further, since the block 130 does not protrude outward from the expected surface 10b of the vertical frame 10 in relation to the horizontal frame described later, the block 130 that plays the most important role when assembling the horizontal frame may be damaged. There is no.

Next, the structure for attaching the horizontal frame to the vertical frame will be described in detail. It should be noted that since the upper frame, the blind frame, and the lower frame can be assembled substantially in the same manner, a structure for assembling the vertical frame is described as a representative example.

The blind 30 assembled to the vertical frame 10 is as follows:
When assembled to the blind positioning means 110, it has a hollow shape in a cross-sectional view in which a glass groove 300 is provided on at least the upper or lower surface such that the groove position matches the glass groove 100 of the vertical frame 10.

Reference numeral 35 denotes a blind joint member,
a, a metal bent material having a U-shaped lower side 350c with a rib side 350d hanging down from the tip of a U-shaped lower side 350c including a vertical side 350b and a lower side 350c. The lower side 350c has an extension 350e that extends outward in the longitudinal direction of the blind 30. An insertion hole 351 is formed in the extension 350e in the center of the width in advance. Width of extension 350e and seamless 3
It is assumed that the extension from zero substantially matches the found and expected dimensions of the glass groove 100. The extension 350e is
When the blind 30 is assembled to the blind positioning means 110, it is set so as to be able to face the block 130 in the vicinity of one of the upper and lower portions of the block 130 (within 10 mm) in parallel with the block 130 (this embodiment). Then block 130
The extension 350e is located below. The upper side 350a of the seamless joining member 40 is screwed to the inner wall of the seamless upper side and fixed.

As a result of this configuration, the screw hole 131 and the insertion hole 351 are both located in the glass groove 100 and are close to and parallel to each other.

The seamless joining member 35 is attached to the vertical frame 10 as described above.
The following procedure is used to assemble the eyelet 30 via the.

First, one section in the longitudinal direction of the blind 30 is fitted to the blind positioning means 110 for temporary assembly. The extending portion 350e is fitted into the glass groove 100 through an opening 111 that has been previously drilled at a predetermined position of the blind positioning means. Thereby, the mounting position of the blind 30 is determined.

Next, the position of the block 130 is adjusted before and after the slit 120 to move the screw hole 131 to an eccentric position so that the screw hole 131 has a partly overlapping portion in the insertion hole 351, and in this state, the screw hole 131 is screwed into the screw hole 131. The tapered screw 50 having a tapered portion at the leading end is screwed and advanced, and it is confirmed whether or not the leading end of the tapered portion can slidably contact any one of the peripheral portions of the insertion hole 351. If the sliding contact is not performed, the sliding contact is performed while shifting the position of the block 130. As a result, when a gap is formed between the front surface of the block 130 and the expected vertical frame surface, a spacer (not shown) is inserted into the gap. In addition, this spacer shall be composed of a plurality of thin plates,
The number is appropriately increased or decreased according to the size of the gap.

Further, the tapered screw 50 is further propelled, so that the projected surface 10b of the vertical
After confirming that any part of the circumference is in the pressed state, the propulsion of the tapered screw 50 is stopped. The determination of the pressed state or the abutted state depends on whether or not the propulsion of the tapered screw 50 is more difficult.

[0028]

[0029]

In the framework of the metal fittings of the present invention, the positioning of the block 130 can be slid forward and backward in the slit, so that the screw hole 131 does not need to be in an eccentric relationship with the insertion hole 351 in advance. Therefore, it is not necessary to increase the positioning accuracy of the insertion hole 351 of the extension 350e. As a result, the screw hole 131 and the insertion hole 351 do not need to be holes having the same diameter, and the insertion hole 351 may have, for example, an elliptical shape. Further, the block 130 is slid and adjusted in the glass groove 100, and the tapered portion of the tapered screw 50 is slidably contacted with any peripheral portion of the insertion hole 351 so that the blind 30 is brought into contact with the prospective surface 10b of the vertical frame 10. Pressing can also be performed. Also, the third of block 130
Since the protruding side 130c is fitted into the third slit 120c, most of the rotational moment force on the block 130 generated when the tapered screw 50 is propelled into the insertion hole 351 is used to form the third protruding side 130c having a very simple structure. ,
It can also be received between the third slits 120c. Also,
The height of the vertical side 400b of the seamless joining member 40 is adjusted (not shown) so that the extending portion 350e is positioned closer to the block 130, and near the screw-side base of the tapered portion of the tapered screw 50. Sliding contact with the periphery of the insertion hole 351
Is pressed against the prospective surface 10b of the vertical frame 10, the rotational moment force can be reduced, and the thickness of the block 130 can be reduced.
