Description

The present invention relates to a connecting fixing bracket, a connecting fixing device, a connecting fixing method, a wall base structure, and a method of constructing a wall base structure. More specifically, the present invention relates to a connecting fixing bracket for connecting and fixing the H-shaped steel and the lip channel steel, a connecting and fixing device, a connecting and fixing method, a wall base structure, and a construction method of the wall base structure.

Conventionally, as the above-mentioned connecting fixing bracket, for example, the one described in Patent Document 1 is known. This fixture is held by sandwiching the object between the tip of the bolt and the end of the fixture body by tightening the bolt in the same way as a vise. In this structure, since the holding force is generated only in the vertical direction, there is a risk of slippage when a load is applied in the horizontal direction. Further, the holding force is generated only by the tightening torque of the bolt, and since the tip of the bolt and the threaded portion of the fixture are separated from each other, there is a possibility that moss of the bolt may occur due to the moment, which is unstable. In such an unstable connected state, it was difficult to quantify the holding force for strength calculation and the like.

Japanese Unexamined Patent Publication No. 2005-325633

In view of such conventional circumstances, the present invention provides a connecting fixing bracket, a connecting fixing device, a connecting fixing method, a wall base structure, and a method for constructing a wall base structure, which can improve the strength against a horizontal load and examine the strength. The purpose is.

In order to achieve the above object, the features of the connecting fixing bracket according to the present invention are the first member engaged with the flange of the H-shaped steel in the configuration of connecting and fixing the H-shaped steel and the lip channel steel, and the said. It has a second member that engages with the lip of the lip channel steel and a tightening means for tightening the first member and the second member, and the first member is penetrated by a long member of the tightening means. A pair of second surfaces having a notch portion orthogonal to the first surface and engaging with the upper corner portion of the flange, an extension piece extending from one second surface along the elongated member, and the above. It has a bent piece that protrudes from the side of the extension piece and is bent at a right angle to the long member side, and the second member is orthogonal to the first surface through which the long member penetrates and engages with the lip. The extension piece of the second member has a second surface having an engaging groove and a third surface having an extension piece facing the second surface and extending along the long member. A first bent piece whose end is bent at a right angle to the long member side, a second bent piece that protrudes from one side of the extension piece and is bent at a right angle to the long member side, and an extension thereof. A third bent piece that protrudes from the other side of the piece and is bent at a right angle to the side opposite to the long member side, and an fitting groove formed by the first bent piece and the second bent piece. The extension piece of the first member is fitted into the fitting groove, the bent piece of the first member faces the extension piece of the second member, and the third bent piece is said. It is to face the lip so that it can be screwed to the lip.

According to the above configuration, the extension piece of the first member extends along the elongated member from one second surface having a notch that engages with the upper corner of the flange of the H-section steel. On the other hand, the extension piece of the second member faces the second surface having the engaging groove with which the lip of the lip channel steel is engaged and extends along the elongated member. The extension piece of the second member has three bent pieces bent at right angles to each of the three directions, and an fitting groove formed by the first bent piece and the second bent piece. Due to this geometric shape and the fitting (arrangement) of the members, the extension piece of the first member is fitted into the fitting groove, and the bent piece of the first member faces the extension piece of the second member. Even if a load of X or Y is applied, the fitting of the members is maintained without separating the members, and a strong connected state can be stably maintained. Moreover, since the third bent piece faces the lip so that it can be screwed to the lip, the metal fittings are fixed to the lip channel steel by screwing, and the strength in the horizontal directions X and Y is further improved and the strength is improved. It is also possible to quantify the holding power for calculations and the like.

The fourth bent piece may face the flange of the H-section steel, and the fifth bent piece may face the flange of the lip channel steel. As a result, the fourth bent piece presses the flange of the H-section steel on its surface, and the fifth bent piece presses the flange of the lip channel steel on its surface. In this way, since it is pressed by the surface, even if it is tightened firmly to increase the holding force, it is possible to prevent each member from being deformed because it cannot withstand the load in the vertical direction due to the tightening, and the holding force due to the deformation. (Strength) can be prevented from decreasing.

In such a case, it is desirable that the fifth bent piece is located immediately below the end of the other second surface of the first member in the vertical direction. As a result, the flange of the H-section steel can be held more firmly, and the strength in the horizontal direction is further improved.

Further, it is preferable that the first surface of the first member and the pair of second surfaces are provided with ribs extending in a direction orthogonal to the notch. As a result, the first member is reinforced against the pressing force on the flange due to the tightening (tightening) of the tightening means, so that each surface of the first member is deformed without being able to withstand the vertical load due to the tightening. Can be prevented, the holding force can be prevented from being lowered due to deformation, and the strength in the horizontal direction is further improved.

Next, the present invention will be described in more detail with reference to the accompanying drawings as appropriate.
As shown in FIG. 1, for example, the connecting fixing bracket 1 according to the present invention has a runner 101 fixed to the lower flange 124 of the lip channel steel 120 with a fixture 104 such as a screw, and a runner 101 at an appropriate distance. It constitutes a connecting and fixing device 10 mainly used in a wall base structure 100 including a stud 102 whose end is fitted along the longitudinal direction Y and a pair of wall materials 103 and 103 fixed to the stud 102. In this example, for example, a channel material having a substantially U-shaped cross section is used for the stud 102, but the present invention is not limited to this. Further, the wall material 103 does not need to be provided on both sides of the stud 102 as in this example, and may be provided on only one side.

As shown in FIGS. 1 and 2, the connecting / fixing device 10 connects and fixes a steel beam 110 made of H-shaped steel arranged on the ceiling slab S and a lip channel steel 120 orthogonal to the steel beam 110. It is provided with a pair of connecting fixing brackets 1. The pair of connecting fixing brackets 1A and 1B have a symmetrical shape that is line-symmetrical with respect to the web 111 of the steel frame beam 110. In the present embodiment, one connecting fixing bracket 1B uses an upper nut 42B having a color different from that of the upper nut 42A of the other connecting fixing bracket 1A as a distinguishing means 11 for distinguishing from the other connecting fixing bracket 1A.

As shown in FIGS. 1 and 2, the connecting fixing bracket 1 is roughly a first member 2 that engages with the lower flange 113 of the steel frame beam 110 and a second member 2 that engages with the upper lip 123 of the lip channel steel 120. 3 and a tightening means 4 for tightening the first member 2 and the second member 3.

As shown in FIGS. 3A and 3B, the first member 2 has a first surface 21 having a through hole 21a through which a bolt 41 as a long member of the tightening means 4 is penetrated, and a steel beam that is orthogonal to the first surface 21 and has a steel beam. A pair of second surfaces 22a and 22b having a notch 23 that engages with the upper angle portion 113a of the lower flange 113 of the 110, and a plate extending from one second surface 22a along the bolt 41 (vertical direction Z). It has a shaped extension piece 24 and a flat plate-shaped bent piece 25 that protrudes from the side portion 24a of the extension piece 24 and is bent at a right angle to the bolt 41 side (inside the metal fitting). In the present embodiment, ribs 29 extending in a direction orthogonal to the notch 23 are continuously (integrally) formed on the first surface 21 and the pair of second surfaces 22a and 22b. As a result, the strength of the ends 26a and 26b of the first surface 21 and the pair of second surfaces 22a and 22b is improved to prevent deformation (opening) due to the tightening torque of the tightening means 4 described later, and hold due to deformation. The force (strength) decreases.

As shown in FIGS. 4A and 4B, the second member 3 has a first surface 31 having a through hole 31a through which the bolt 41 of the tightening means 4 is penetrated, and is orthogonal to the first surface 31 and engages with the upper lip 123. It has a second surface 32 having an engaging groove 33 and a third surface 34 having a plate-shaped extension piece 35 facing the second surface 32 and extending along a bolt 41.

The extension piece 35 of the second member 3 has a first flat plate-shaped first bent piece 35a whose end is bent at a right angle to the bolt 41 side, and a bolt 41 side protruding from one side portion 35d of the extension piece 35. A flat plate-shaped second bent piece 35b bent at a right angle to the above, and a flat plate-shaped third bent piece 35b protruding from the side portion 35e on the fourth surface 36 side (the other side) of the extension piece 35 and bent at a right angle to the bolt 41 side. It has a piece 35c and a fitting groove 37 into which an extension piece of the first member is fitted between the first bent piece 35a and the second bent piece 35b. The third bent piece 35c has a screw fastening hole 38 for attaching the screw 39 to the upper lip 123.

In the present embodiment, the second member 3 further includes a fourth surface 36 that is orthogonal to the first surface 31, the second surface 32, and the third surface 34. Further, the second surface 32 of the second member 3 further has a flat plate-shaped fourth bent piece 32a whose end portion is bent at a right angle toward the outside. The fourth surface 36 of the second member 3 further has a flat plate-shaped fifth bent piece 36a whose end is bent at a right angle to the bolt 41 side.

As shown in FIGS. 1 and 2, the tightening means 4 is roughly a bolt 41 as a long member attached to the first surface 31 of the second member 3 and penetrating the first surface 21 of the first member 2, and a first member. It is composed of an upper nut 42 and an upper washer 44 in contact with the first surface 21 of one member 2, and a lower nut 43 and a lower washer 45 in contact with the first surface 31 of the second member 3.

Here, the mounting method of the connecting fixing bracket 1 will be described by taking the construction method of the wall base structure 100 as an example with reference to FIGS. 1, 2, 5-9. In FIGS. 6 and 7, the lower flange 113 of the steel beam 110 is omitted for convenience of explanation.
As described above, in the connecting / fixing device 10 of the wall base structure 100 according to the present embodiment, the colors of the upper nuts 42A and 42B are different as the means 11 for distinguishing the pair of symmetrical connecting / fixing metal fittings 1A and 1B. .. Here, for example, by attaching (screwing) the upper nut 42 to the bolt 41 before the construction, the operator always visually checks the upper nut 42 at the time of construction. Therefore, it is possible to confirm which side of the H-shaped steel (steel beam) 110 is attached to the web 111 by changing the color of the upper nut 42 without deteriorating workability, and it is possible to prevent construction mistakes.

Next, the upper lip 123 is engaged with the engaging groove 33 of the second member 3 to which the bolt 41 is fixed to the first surface 31 via the lower nut 43 and the lower washer 45, and the second member 3 and the lip groove are engaged. Engage with the shaped steel 120. Then, the first member 2 is engaged with the upper corner portion 113a of the lower flange 113 of the steel frame beam 110 via the bolt 41 with the pair of cutout portions 23, 23. Then, by tightening the upper nut 42 to the bolt 41, the first and second members 2 and 3 are tightened. The connecting fixing bracket 1 in this example can correspond to, for example, a steel beam 110 having a wall thickness t of 8 to 50 mm for the lower flange 113 shown in FIG.

Here, as shown in FIGS. 2 and 9, since the extension piece 24 of the first member 2 is fitted into the fitting groove 37 of the second member 3, the bottom of the fitting groove 37 causes the lip channel steel 120 to be in the longitudinal direction Y The movement in the (outside the wall surface) direction is restricted, and the movement in the horizontal direction X (inside the wall surface) is also restricted by the first bent piece 35a and the second bent piece 35b. Further, as shown in FIGS. 2, 8 and 9, the bent piece 25 of the extension piece 24 of the first member 2 faces the extension piece 35 of the second member 3, and the extension piece 35 of the second member 3 is the first. The bi-bent piece 35b faces the extension piece 24 of the first member 2. In this way, since the first and second members 2 and 3 are fitted and abutted against each other, the strength can be improved with respect to the wall surface inner direction X and the wall surface outer direction Y.

Further, as shown in FIGS. 1, 2, 5 and 8, the fourth bent piece 32a of the second member 3 comes into surface contact with the back surface 113b of the lower flange 113 of the steel frame beam 110 and presses by tightening the tightening means 4. In addition, the fifth bent piece 36a comes into surface contact with the inner surface 122a of the upper flange 122 of the lip channel steel 120 and presses it. In this way, since the surfaces are contacted and pressed, the holding force can be improved, and even if the tightening force is excessively tightened, the second surface 32 and the fourth surface 36 of the second member 3 due to the tightening torque are used. Can be suppressed from being deformed (opened), and a decrease in holding force (strength) due to deformation can be prevented. Moreover, since the fifth bent piece 36a is positioned (opposed) directly below the vertical direction Z of the end portion 26b of the other second surface 22b of the first member 2 with the lower flange 113 interposed therebetween, the tightening torque is efficiently applied. It can be used to hold the lower flange 113.

Further, as shown in FIG. 5, the third bent piece 35c is opposed to the upper lip 123, and as shown in FIGS. 1 and 2, the third bent piece 35c is screwed and fixed to the upper lip 123 with a screw 39 through the screw fastening hole 38. As a result, the connecting fixing bracket 1 is fixed to the lip channel steel 120, so that the strength is further improved in the wall surface inner direction X and the wall surface outer direction Y. Further, it is possible to quantify the allowable proof stress of the connecting fixing bracket 1 by carrying out a strength test or the like, and for example, it is possible to examine the strength of the partition wall. Then, the connecting fixing bracket 1 on the other side is also attached in the same manner to construct the wall base structure 100.

Finally, the possibility of other embodiments of the present invention is mentioned. The same members as those in the above-described embodiment are designated by the same reference numerals.
In the wall base structure 100 of the above embodiment, the runner 101 is orthogonal to the lip channel steel 120, but it is also possible to make the runner 101 parallel to the lip channel steel 120. Further, in the above embodiment, the tightening means 4 is composed of bolts 41 as long members and upper and lower nuts 42, 43, but the first member 2 and the second member 3 can be tightened (tightened). If so, there is no particular limitation. For example, a split pin, a snap pin, a pin, etc., which can be fixed by sandwiching the H-shaped steel 110 and the lip channel steel 120 and tightening the first member 2 and the second member 3. Further, for example, it is also possible to form a female screw (screw hole processing) in the through hole 21a of the first member 2 with a tap and fasten it with a bolt 41. It is also possible to fasten and fix the first and second members 2 and 3 with drill screws.

Further, in the above embodiment, as the distinguishing means 11 of the pair of connecting fixing brackets 1A and 1B of the connecting fixing device 10, the color of the upper nut 42 screwed into the bolt 41 of the tightening means 4 is changed. However, the distinguishing means 11 is not limited to this, and may be, for example, a difference in the color of the bolt 41, a mark such as a mark on the first member 2 or the second member 3, and the like. Anything is fine.

In the above embodiment, the second member 3 is provided with the fourth surface 36, the second surface 32 of the second member 3 is provided with the fourth bent piece 32a, and the fourth surface 36 of the second member 3 is provided with the fifth bent. Although the piece 36a is provided, it is also possible to omit such a flat plate-shaped bent piece so that, for example, the protruding end portion is brought into contact with the piece 36a. However, as in the above embodiment, by bringing the fourth bent piece 32a and the fifth bent piece 36a into surface contact with the steel frame beam 110 and the lip channel steel 120, it is possible to improve the holding force and prevent deformation (opening). In this respect, the above embodiment is excellent.
