Description

[Detailed description of the invention] The present invention relates to a mounting device for a building guardrail that is attached to the wall of a hallway in a building, and includes the connecting portion between the guardrail body and a movable support rod, and the connecting portion between the movable support rod and the mounting base. This prevents rattling in the connecting parts, and prevents the connecting parts between the guardrail body and the movable support rod from loosening caused by careless rotation of the movable support rod, so that they can be maintained in the best condition for a long time. The present invention provides a building guardrail mounting device that can be used.

The structure of the present invention will be explained based on the embodiments shown in the attached drawings. Reference numeral 1 denotes a mounting device, and the mounting base has an opening on the negative side, a threaded part 2 carved inside, and a long hole 4 bored in the bottom part 3. 5, a movable support rod 7 having a threaded portion 6 carved on its outer circumferential surface, a lock nut 8 screwed into the movable support rod 7 from the root side, and a screw hole 9 inserted through the tip side of the movable support rod 7. It consists of a locking piece 11 that is bored approximately in the center and has hook-shaped protrusions 10 and 10 facing each other at the upper and lower ends of the threaded part 6 carved on the outer circumferential surface of the movable support rod 7. A notch 12 for rotating the movable support rod 7 is formed approximately in the center.

Reference numeral 13 denotes a guardrail fixed to the wall surface 14 by the mounting device 1, and includes a guardrail main body 16 having a pair of projecting pieces 15, 15 protruding from the back surface near the center facing in vertically opposite directions, and a guardrail main body 16 that is fitted and locked to the guardrail main body 16. The filling body 17 is made of

To explain the installation procedure of the guardrail 13 in this installation device 1, the installation base 5 is fixed to the wall surface 14 with bolts 18 through the long holes 4 drilled in the bottom 3 of the installation base 5.

Next, the base side of the movable support rod 7, into which the lock nut 8 has been screwed in advance, is screwed into the threaded portion 2 of the mounting base 5 to connect the movable support rod 7 to the mounting base 5.

When this work is completed, the movable support rods 7 are adjusted by moving them back and forth so that the tips of the movable support rods 7 are located on the same line using the water system stretched over the wall surface 14.

Next, the hook-shaped protruding edge 10 of the hooking piece 11 is fitted into the protruding piece 15 of the guardrail body 16 from the longitudinal end of the guardrail body 16 .

After that, screw the tip side of the movable support rod 7 into the screw 7L9 of the locking piece 11, press the back side of the guardrail body 16 with the tip of the movable support rod 7, and connect the tip of the movable support rod 7 with the locking piece. The guardrail body 16 is formed by the hooked edges 10 of 11.
The protruding pieces 15 are pressed together in a pinch-like manner and connected.

Finally, the lock nut 8 is pressed against the tip of the mounting base 5 to lock the movable support rod 7 to the mounting base 5 to prevent the movable support rod 7 from rotating inadvertently, thereby completing the installation work.

In addition to forming a notch 12 on the outer periphery of the threaded portion 6 in order to rotate the movable support rod 7, a through hole 19 is bored at an appropriate position in the threaded portion 6 as shown in FIG. The tip of a screwdriver or the like may be inserted into the through hole 19 and rotated.

5 and 6 show other embodiments of the mounting position of the building guardrail according to the present invention, and this mounting device 1
has a mounting base 5 with one side open and a threaded part 2 carved inside, a long hole 4 bored in the bottom part 3, a movable support rod 7 with a threaded part 6 carved on the outer peripheral surface, and this movable It consists of a lock nut 8 that is screwed into the support rod 7 from the root side, and a flat plate-shaped locking piece 11 that has a screw hole 9 inserted through the tip end of the movable support rod 7 approximately in the center.

Moreover, the guardrail main body 16 using this mounting device is
A hook-shaped portion is formed on the protruding pieces 15, 15 that protrude from the back surface thereof.

The procedure for installing the guardrail 13 using this installation device 1 is as follows:
The steps shown in FIGS. 1 and 2 are similar to those shown in FIGS. 1 and 2, except that the flat plate-shaped hooking piece 11 is inserted and hooked from the length direction into protrusions 15 and 15 having opposing hook-shaped portions protruding from the back surface of the guardrail body 16. The installation procedure is similar to that shown in .

As described above, the present invention involves screwing a movable support rod into the screw hole of a locking piece that is engaged with a protrusion provided on the back side of the guardrail body, and attaching the back side of the guardrail body with the tip of the movable support rod. Since the movable support rod and the latch piece are pressed together by pressing the protruding piece of the guardrail body in a pinched manner, the latch piece is able to withstand external forces such as collisions with the guardrail body. The reaction force acts and absorbs the clearance of the threaded joint to prevent rattling at the joint between the guardrail body and the movable support rod, and on the mounting base side, the lock nut at the base of the movable support rod A pulling force is applied in the direction toward the tip of the movable support rod, and the clearance of the screw connection is similarly absorbed, preventing rattling and ensuring a strong overall installation.
It can be used in the best condition for a long period of time.

Furthermore, by press-contacting the tip of the movable support rod to the back surface of the guardrail body, strong frictional resistance is generated on the press-contact surface and the screw connection, and by press-contacting the lock nut and the tip of the mounting base, the screw connection is prevented. The movable support rod is firmly fixed due to the frictional resistance generated in the parts, and the movable support rod will not be inadvertently rotated due to external force or vibration during use.
