Description

[Detailed Description of the Invention] This invention relates to a roof support device for supporting the tip of the roof on the opposite side of the pillar in a simple garage in which the roof is supported in a cantilevered manner on the upper part of the pillar.

Conventional support devices of this type simply fix the upper end of one reinforcing rod to the rafters of the roof, either directly or via a fixing metal fitting, and the lower end is planted directly into concrete on the ground or via an anchor. It was fixed. By the way, it is very difficult to maintain a constant height of the tip of the roof from the ground. If the upper end of the reinforcing rod is fixed to the roof in advance and the lower end of the reinforcing rod is inserted into the concrete and fixed, the lower end of the reinforcing rod may not be fixed to the concrete due to shaking or vibration of the roof. Since it is easy to completely fix the reinforcing rod, the upper end of the reinforcing rod is fixed to the rafter after only the lower end of the reinforcing rod or the anchor is buried and solidified in ground concrete. However, as mentioned above, since the height of the tip of the roof from the ground is not constant, it is not easy to fix the upper end of the reinforcing rod to the rafter.

In view of the above points, the purpose of this invention is to provide a roof support device that is easy to install, does not interfere with installation even if the distance between the roof and the ground is not constant, and has sufficient strength. .

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

FIG. 1 is a front view showing a simple garage according to this invention, and the simple garage is constructed by supporting the lower end of a sloped roof 3 in a cantilevered manner on the upper part of a support 2 erected on a ground 1. Reference numeral 4 represents a cane, and reference numeral 5 represents a rafter constituting the roof 3, the lower end of which is connected to the pillar 2. A is a reinforcing rod that is a component of the roof support device according to this invention, and its upper and lower ends are connected to the upper and lower locking rods that are other components of the support device, respectively, as will be described later. It is fixed to the rafter 5 and the ground 1 by tools B and C.

Fig. 2 is a partially omitted enlarged side view seen from the direction of the arrow in Fig. 1. The roof support device comprises a long rod-shaped reinforcing rod A extending from the vicinity of the upper end of the rafter 5 to a position on the ground corresponding to the rafter 5, an upper fastening device B fixed to the underside of the rafter 5 in the vicinity of the upper end,
and a lower fastening device C which is buried in the ground 1 at a position corresponding to the upper end of the rafter 5.

The reinforcing rod A is formed by connecting at least two elongated members 6 and 7, which are divided into upper and lower parts, so that they can slide freely in the longitudinal direction and can be fixed at appropriate positions. More specifically, the upper and lower elongated members 6 and 7 are made of circular tubes, and the lower elongated member 7 is slid from the lower end of the upper elongated member 6 into its hollow part in a nested manner. It can be inserted freely. and,
The lower end of a bolt 9 constituting a length adjuster 8 is fixed to the upper end of the lower elongated member 7 by a fixing member 10. The bolt 9 has a thread along its entire length or at least on its upper part, and its lower end is screwed into the central hole 11 of the cylindrical fixing member 10, and the lower end of the bolt protruding downward from the fixing member is welded to the fixing member 10. The fixing member 10 is pushed into the hollow part at the upper end of the lower elongated member 7, and the screw 12 is passed through the member from the outside of the lower elongated member 7 and inserted into the screw hole provided in the fixing member 10. Screw in bolt 9
is fixed to the lower elongated member while extending from the upper end of the lower elongated member in the axial direction of the lower elongated member.

The nut 13, which is another component of the length adjuster 8, has almost the same shape as the fixing member 10, and is inserted into the hollow part of the middle part of the upper elongated member 6. A screw 14 penetrating the member from the outside is screwed into the screw hole provided in the nut 13, and the nut 13 is attached to the upper elongated member with the central screw hole 15 parallel to the axial direction of the upper elongated member. It is fixed to the member.

Then, insert the upper part of the lower elongated member 7 from below into the hollow part of the upper elongated member 6, and insert the upper end of the bolt 9 protruding from the upper end of the lower elongated member into the screw hole 15 of the nut 13. By screwing into the upper and lower elongated members 6 and 7, the upper and lower elongated members 6 and 7 are connected to each other so that they can be slid in the axial direction by rotation of both members in opposite directions, and can be fixed at any position.

Further, a hook-shaped hook 19 is attached to the upper end of the upper elongated member 6 by a fixture 16. The fixing tool 16 consists of a fixing member 17 having almost the same shape as the fixing member 10 and a screw 20, and a straight portion of a hook-shaped hook 19 passes through a central hole 18 of the fixing member, and a portion protrudes downward from the fixing member. is welded to the fixing member, and the fixing member 17 is inserted into the hollow part at the upper end of the upper elongated member 6, and a screw 20 is passed through the member from the outside of the upper elongated member, and the fixing member 17 is welded to the fixing member 17. The hook 19 is fixed to the upper elongated member 6 by screwing into a provided screw hole, with the locking portion of the hook 19 protruding upward from the upper end of the upper elongated member 6. The locking portion of the hook 19 is bent at an angle smaller than a right angle.

A hook-shaped hook 19e is also attached to the lower end of the lower elongated member 7 by a lower fixture 21 that is substantially similar to the upper fixture 16. Regarding the members corresponding to the constituent members of the upper fixture, e will be added to the former reference numeral, and the explanation will be omitted. The lower hook 19e projects downward from the lower end of the lower long member 7, and the locking portion is bent at a substantially right angle in the opposite direction to the hook 19. Further, a hole 22 for mounting a stopper pin 23 is provided at the tip of the locking portion.

As shown in Figs. 2 and 3, the upper fastening device B is provided on both side walls 25 of a fixing member 24 having a substantially inverted U-shaped cross section, and has pins 27 and stoppers 28 which are perpendicular to the side walls at the lower and upper parts of the side walls.
The bottom wall 26 of the fixing member 24 is fixed to the
is fixed with a screw 29 to the underside near the upper end of the rafter 5. The pin 27 and the stopper member 28 can insert the upper hook 19 of the reinforcing rod A between them with the lower part of the reinforcing rod inclined toward the support 2, but when the hook 19 is engaged with the pin 27, it is spaced upward on the opposite side to the pin 27 with respect to the hook so that it cannot be pulled out in the direction in which the reinforcing rod is being stretched as shown in Fig. 3.

As shown in FIG. 4, the lower anchor C is an anchor member 30 formed by bending a round bar into an approximately Ω shape.
and the anchor member 30 at a position spaced downward from the upper end of the anchor member by a distance slightly larger than the diameter of the locking portion of the lower hook 19e.
A flat bottom plate 31 is horizontally welded to the bottom plate. The lower anchor C is embedded in the ground at a position slightly away from directly below the upper anchor B on the opposite side of the support column, and contacts the bottom plate 31 with the ground surface, and is an anchor member. 30 is fixed with a portion above the bottom plate protruding in an inverted U shape.

In this case, the bottom plate 31 acts as a positioner when determining the amount of embedding of the anchor member, or in other words, the amount of protrusion of the lower anchor member from the ground surface, and the lower anchor member C whose upper part is fixed to the ground and the ground surface. An insertion hole through which the lower hook 19e can be inserted and hooked is provided between the lower hook 19e and the lower hook 19e. The bottom plate 31 therefore facilitates the installation of the lower anchor. Further, since the anchor member 30 is formed into an Ω-shape, the lower anchor is firmly fixed to the ground.

When using a roof support device having the above-mentioned configuration, the upper end of the reinforcing rod A in a free state should be brought closer to the upper stopper B, and the lower side of the reinforcing rod should be closer to the support column 2 than directly below the upper hook. When it is moved to the side and tilted, the tip of the upper hook 19 of the reinforcing rod can be inserted between the pin 27 of the locking tool B and the retaining member 28, and the hook can be hooked to the pin 27. . Therefore, after the upper hook 19 is hooked to the upper hook B in this manner, the lower end of the reinforcing rod A is brought closer to the lower hook C side, and the tip of the lower hook is hooked to the lower hook C. Stop.

In this case, since the length of the reinforcing rod A is not equal to the distance between the upper hook B and the lower hook C, if the lower hook cannot be hooked to the lower hook C, the lower elongated member 7 is If it is rotated to the left or right, the length of the reinforcing rod A will be lengthened or shortened by the action of the length adjustment tool 8, so that the length of the reinforcing rod A will be just enough to hook the lower hook to the lower locking tool C. It can be done.

When inserting the lower hook into the insertion hole of the lower locking tool C, the lower end of the hook may come into contact with the upper surface of the bottom plate 31, but if the bottom plate 31 is made of metal, the bottom hook of the bottom plate Since the amount of loss can be reduced, it is possible to apply force to the hook to reliably and easily attach it to the lower locking device C, thereby preventing the lower hook from gradually becoming larger and more damaged in the ground when there is no bottom plate. be done. Therefore, the bottom plate 31 also functions to guide the lower hook and prevent damage to the ground.

Then, the tip of the lower hook hooked on the lower hook C is projected to the opposite side of the lower hook, so that
A stopper pin 23 is inserted into a hole provided at the tip of the hook to prevent the hook from coming off the lower stopper. It is preferable to screw in a set screw instead of the stopper pin.

In this way, the reinforcing rod A is stretched between the upper stopper B and the lower stopper C, and prevents the roof 3 from being blown up by strong winds. With the reinforcing rod positioned in the direction in which it is hooked to the lower anchor C as described above, even if the tip of the roof falls somewhat due to wind or snow loads, the pin 27 of the upper anchor B will not move. Since the retaining members 28 are spaced apart in an oblique direction that is substantially parallel to the bending direction of the upper hook, the hooks do not directly receive the downward movement force of the roof, protect the reinforcing rods, and prevent the pins 27 and retaining members 28 from perpendicular to each other. The distance is slightly less than the height of the downward bend of the top hook, so that the top hook does not become disengaged from the top catch during lowering of the roof tip.

In the above embodiment, the fixing member 10 and bolt 9 of the length adjuster were attached to the lower elongated member 7, and the nut 13 was attached to the upper elongated member 6, but the attachment positions may be reversed. Not even.

As described above, according to this invention, with a relatively simple structure, it can be easily installed in a simple garage where the distance between the roof and the ground is not constant, and the tip of the roof can be supported on the ground with sufficient strength. It can be easily installed and used in an existing simple garage, or can be removed.
