Description

[Detailed description of the invention] This invention relates to a support device for a balcony support leg that can support a balcony support leg that is installed overhanging a sloped roof with high stability on any slope of the roof. be.

As shown in FIG. 1, this type of conventional support device is constructed by fixing a pair of one-shaped brackets 3, 3 to the upper surface of a rectangular tube 2 having a square cross section, and removes foot odor F from the vertical portion 3a of the bracket. ,3
Insert the lower end of the balcony support leg 4 between the vertical parts 3 and 3.
A, 3A and the supporting leg 4 are attached to the supporting leg 4 by tightening them with bolts 5a, 5b. After tilting the foot odor, Pol) 5b is completely tightened and fixed.

With such a configuration, as the roof slope increases, the line of action G of the balcony load acting through the poles 5a and 5b tends to appear outside the lower side of the contact surface of the square tube 2 with the roof. (Symbol G,) Therefore, since a couple acts on the foot odor F, 5 a' and 5 b tend to loosen, and the stability of the square tube 2 is low. When the bolt loosens, the square tube 2 becomes the arrow There is a risk of falling in direction A and causing a fatal accident.

In particular, when the roof is tiled and the square tube 2 has to straddle the tiles above and below, the angle of inclination of the square tube becomes even larger, further aggravating the above-mentioned tendency. Therefore, it is no longer possible to stably install the balcony support legs.

If the length and width of the square tube 2 in the direction of the roof slope are increased so that the line of load action G on the balcony falls within the area of the bottom of the square tube, the stability of foot odor may be improved. ,
In this case, the supporting leg support device becomes large in size, resulting in large consumption of materials and high cost.

Also, the appearance of a large square tube with its midsection inclined towards the step of the tile is not pleasing in terms of appearance.

This idea was made to eliminate the above-mentioned defects, and the support angle can be easily adjusted for a wide range of roof slopes, and the balcony legs can be supported with very high stability regardless of the slope. The purpose of the present invention is to provide a balcony leg support device that is capable of easily adjusting the level of a balcony.

Next, an embodiment of this invention will be described based on the drawings.

The support device according to this invention generally consists of legs 9 and 1 that are spaced apart in the direction of the slope of the roof and that come into contact with the top surface of the roof.
0, and integrally has an arc-shaped back part 6 with an upwardly convex cross section, and a balcony support leg which is placed astride the back part 6 so as to be slidable in the circumferential direction thereof. 4, and a saddle B which is swingably connected to the lower end of the 4.

The back part 6 of the bridge part A has an arc shape with a cross section that is almost semicircular,
By connecting the lower end portions 6a and 6b of the back portion with a web 7 to form a semicircular hollow portion 8, the bending strength of the back portion 6 against a load applied in the vertical direction is reinforced.

A first leg portion 9 and a second leg portion 10 are integrally formed below the lower end portions 6a and 6b of the back.

The legs 9, 10 are separated in the direction of the roof slope.

Also, dovetail grooves 11. which open downward at the lower ends of both legs.
12 are formed, and an anti-slip member 13 made of rubber or other material with a large friction coefficient is fitted into these dovetail grooves so as to protrude downward.

In this embodiment, the leg part 10 on the lower side of the roof is longer than the leg part 9 on the higher side by the thickness of one roof tile in length from the lower back ends 6 a , 6 b . There are steps between the parts.

Furthermore, a mounting hole (not shown) is bored in the back part 6 at a symmetrical position with respect to the center in the longitudinal direction and in the center in the circumferential direction.

On the other hand, the saddle part B includes a pair of connecting plates 1 that stand vertically upward on the upper surface of the shoe body 14 whose cross section forms an arc with a downward concave surface.
The shoe body 14 has the same radius of curvature as the back part 6 of the bridge part, and the back part 6
It can be placed across the upper surface and slid on the upper surface of the back in the circumferential direction.

Further, the shoe body 14 is provided with elongated holes 16, 16 which are elongated in the circumferential direction on the outer sides of the coupling plates 15, 15, respectively.

The distance between the same elongated holes is equal to the distance between the mounting holes bored in the back of the bridge part.

In this way, a bolt 17 is inserted from inside the hollow part 8 of the bridge part into each attachment hole and the long hole 16 of the shoe body, and the shaft part of the bolt projects upwardly and outwardly from the long hole.
By screwing the nut 19 through the bolt 8, the saddle part B straddles the back of the bridge part A.

The connecting plate 15 has a vertically long elongated hole 20 and a round hole 2.
1 is provided.

Then, insert the lower end of the balcony support leg 4 between both connecting plates, pass the bolt 22 from the elongated hole 20 of one of the connecting plates through a round hole (not shown) provided in the support leg, and insert the bolt 22 through the long hole 20 of one of the connecting plates. The saddle B is coupled to the supporting leg 4 by screwing a nut (not shown) onto the tip of a bolt protruding from the hole.

Based on this configuration, in order to fix the balcony support leg 4 on the roof, first loosen the pole 17.22 a little so that the bridge part A, the saddle part B, and the support leg 4 can rotate freely relative to each other, and then Both legs 9 and 10 of part A are firmly seated on tile 1.

In this case, the back part 6 of the bridge part is slidable in the circumferential direction with respect to the saddle part B, and the lower surface of the shoe body acts to guide the back part of the bridge part, so that the back part 6 of the bridge part can slide smoothly and quickly according to the roof slope. It can be rotated to bring both legs into contact with the tiles.

In addition, since there is a step between both legs, even if there is a step in the tile roof just below the supporting leg 4, the legs 9 and 10 can be brought into contact with the upper and lower tiles, respectively, as shown in Fig. 2. Thus, the piece can be seated on the roof in a stable state regardless of the step 1a between the upper and lower tiles.

In this case, since the bridge and the saddle are slidable in the circumferential direction and the saddle is rotatable with respect to the supporting legs, the legs 9 and 10 of the bridge are moved along the slope of the roof. By slightly moving in the vertical direction, the legs 9 and 10 can be easily seated securely and with high stability on the upper and lower surfaces of the tiles, respectively.

Next, in this state, tighten the nut 19 finally and tighten the piece A.
and fix saddle B.

Next, since the long holes 20 are formed in the connecting plate, move the supporting legs 4 up or down so that the deck of the balcony is level, and when the deck is level, remove the bolts 2.
2 is finally tightened, round holes are drilled in the supporting leg 4 corresponding to the round holes 21 of the connecting plate 15, and nuts 24 are screwed onto the bolts 23 that pass through these round holes, thereby securing the saddle part B.
is prevented from rotating around the bolt 22.

In this way, when the balcony support leg 4 is supported on the roof, the load of the balcony applied to the support leg 4 is transferred to the saddle body 14 having an arcuate cross section via the connecting plate 15.15 of the saddle B.
The load is then dispersed and transmitted to the back section 6 of the bridge section A, which also has an arcuate cross section, and the bridge section A attempts to evenly distribute the load onto the roof from the upper and lower legs 9 and 10.

Therefore, the saddle and bridge support the load in the most structurally stable state.

Further, since the back portion 6 has a semicircular shape and is reinforced by the web 7, it has sufficient bending strength against vertical loads.

Another embodiment of the present invention is shown in FIG.
As in the first embodiment, a dovetail groove 25 with an upward opening is provided on the inner side near the top of the back portion 6 so as to avoid the troublesome work of inserting a hand or a tool into the hollow portion 8 to prevent rotation. It was formed.

That is, since the width of the dovetail groove 25 is set to be slightly wider than the distance between the heads of the bolts 17, the bolts 17 cannot rotate and can only move in parallel.

Therefore, in this embodiment, in addition to the effects of the previous embodiments, the work of fastening the saddle B and the bridge A can be performed extremely efficiently, and the saddle can be moved in the longitudinal direction with the bolt 17 inserted. Therefore, the bridge section can be arbitrarily moved in relation to the balcony construction position to prevent it from hitting the wall or protruding from the roof, and the saddle section B can be installed at the longitudinal center of the bridge section A. The appearance of the lower end of the lower leg can be easily improved.

In the above example, an example was shown in which a step was provided between the legs 9 and 10 so that high stability could be obtained even when the bridge part was supported by straddling the stepped part of the tile. However, the legs are not limited to those mentioned above, and if they can be supported by the flat upper surface of the roofing material, the lower end 6a of the back 6 can be used as shown in FIG.
, 6b with legs 9 and 10 at the same height.
It goes without saying that ' may also be used.

As described above, the balcony leg support device according to this invention has the following effects.

First, the upper surface of the bridge and the lower surface of the saddle have circular arc cross-sectional shapes complementary to each other, and the saddle sits on the upper surface of the bridge so that it can freely slide in the circumferential direction, so it can be applied to a wide range of roof slopes. On the other hand, the lower surface of the bridge can be brought into close contact with the roof of any slope, providing distributed support and highly stable support for the balcony load.

Second, since the upper surface of the bridge and the lower surface of the saddle are in contact with each other on curved surfaces with the same radius of curvature, the balcony load is evenly distributed, strong bending strength is obtained, and the supporting angle of the bridge can be adjusted. Since a mutual guiding effect is obtained during this process, adjustment work according to the slope can be easily performed.

Thirdly, since the semicircular bridge is rotatable relative to the saddle, the line of action of the balcony load always falls within the bottom surface of the bridge, and therefore the bridge may fall over due to the balcony load. It has very high support stability.

Fourth, the bridge and the saddle are connected by inserting a bolt into a long hole circumferentially in the saddle body and screwing a nut into the bolt, so the bridge can be attached to any slope of the roof. The bridge part and the saddle part can be fixed by simply rotating the parts and tightening the bolts and nuts, and there is no need for processing to fix them depending on the roof slope.

Fifth, since the saddle part is connected to the support leg so that it can rotate freely and move up and down with a bolt that passes through a vertical hole provided in the connecting plate, when the bridge part is straddled over a stepped part of a tiled roof. In addition, it can be installed so that it is seated on the upper and lower tiles in a reliable and stable state, and the level of the balcony can be easily adjusted.

Sixth, since the saddle is rotatable with respect to both the support legs and the bridge, if there is a step in the tile roof just below the support, it is possible to provide a leg that protrudes with a step on the lower surface of the bridge. In this case, it is possible to move the bridge along the slope of the roof and adjust the seating position of the legs on the tiles to ensure that the bridge is seated in a stable position on the tiles above and below the roof step. can.
