The base 10 is made of a metal material made of an extruded shape material such as a hard synthetic resin or aluminum, and a base cover 11 that is crowned and locked to the base 10. The locking portion 13 is locked to the locking step portion 12 formed at the upper and lower edges of the base 10 so that the base 10
It is worn with a crown. An attachment step 14 is formed in the center of the back surface of the base 10. By forming the upper end edge of the attachment step 14 in a hook shape, an adjusting member 3 on the guardrail 1 side described later is formed.
It can be locked to the flange 15 of the. Reference numeral 16 denotes an anchor buried in the wall surface 2. A female screw is formed in a projecting portion from the wall surface 2 to form a screw receiving portion 6 for receiving a fixing screw 5 described later. The adjusting member 4 on the side of the wall surface 2 according to this embodiment is formed in a cylindrical shape with a bottom having a contact surface 17 with the wall surface 2. An insertion hole 18 is formed, and a female screw portion 19 is formed on substantially the entire inner periphery of the cylindrical portion. The adjusting member 3 on the guardrail 1 side combined with the adjusting member 4 is a bottomed cylindrical member having a cylindrical portion formed with a male screw portion 20 to be screwed to the female screw portion 19 on the distal end side of the outer peripheral wall, An insertion hole 22 for the fixing screw 5 is formed in the center of the contact surface 21 with the base 10 in which the flange portion 15 is bulged around the root side of the cylindrical portion. The female screw 19 formed on the adjusting member 4 installed on the wall surface 2 is formed on substantially the entire inner peripheral surface of the cylindrical portion, and is formed on the adjusting member 3 installed on the guard rail 1 side. The male screw part 20 is biased toward the tip half of the cylindrical part,
Since the thread is formed so as to protrude from the outer peripheral wall, the pair of adjusting members 3 and 4 are screwed into each other to advance and retreat, and then the adjustment is performed. There is no danger that the appearance after installation is impaired without any part of the 20 being exposed, and that dust and the like accumulate on the male screw portion 20. Therefore, according to this embodiment, first, a pair of adjusting members
After the screws 3 and 4 are combined by screwing the female screw portion 19 and the male screw portion 20, an insertion hole 18 formed in the adjusting member 4 on the wall surface 2 side is formed.
The anchor 16 buried and fixed to the wall 2 is inserted through the wall. At this time, the screwing depth of the pair of adjusting members 3 and 4 is
The adjustment is performed such that the contact surfaces 21 of the adjustment members 3 on the guardrail 1 side are arranged on substantially the same plane. Thereafter, the fixing screw 5 is inserted from the front side of the base 10 and the screw receiving portion of the anchor 16 is inserted while using the flange 15 of the adjusting member 3 on the guardrail 1 side and the hook 23 of the base 10 as positioning means. 6 and fix the base 10
The base cover 11 is elastically mounted on the base 10 and the installation of the guardrail 1 is completed. In the embodiment described above, the case where the screw receiving portion 6 is formed at the tip of the anchor 16 has been described.
As shown in FIG. 3, a screw receiving portion 6 can be formed on a fixing member 24 provided separately from the anchor 16, and the fixing screw 5 can be screwed into the screw receiving portion 6. In this case, the fixing member 24 is attached to the tip of the anchor 16 by the wall surface 2.
The female screw part 26 formed at the end opposite to the screw receiving part 6 is screwed into the male screw part 25 formed more protrudingly and fixed.
Also, a flange is formed on the edge of the fixing member 24 on the side where the female screw portion 26 is formed.
If the adjusting member 4 on the side of the wall surface 2 can be fixed in a state where the fixing member 24 is fixed and the fixing member 24 is fixed, the adjusting member 3 on the side of the base 10 on the hook portion 23 of the base 10 can be fixed.
It can be adjusted in a state in which it is temporarily fixed by being locked to the flange portion 15, and workability is improved. FIG. 4 (a) shows another embodiment of the screw receiving portion 6 of the present invention, in which the screw receiving portion 6 is formed integrally with the adjusting member 4 on the wall surface 2 side. That is, the adjusting member 4 on the side of the wall surface 2 in this embodiment.
A fixed projection having a screw receiving portion 6 on the tip end side
28 is formed, and a female screw portion 29 provided on the contact surface 17 side of the fixed protrusion 28 with the wall surface 2 is screwed into a male screw portion 25 formed at the tip of the anchor 16 to thereby form a wall surface. Fixed to 2. Therefore, in this embodiment, after the female screw portion 29 is screwed into the anchor 16 to fix the adjustment member 4, the adherend 1
The base 10 is temporarily fixed by locking the hook 23 of the base 10 to the flange 15 of the adjustment member 3 on the side, and then the fixing screw 5 is screwed into the screw receiving portion 6 to install the base 10. You. As described above, the fixing member 24 forming the screw receiving portion 6 is fixed simultaneously with the adjusting member 4 (see FIG. 3), or as shown in FIG. When formed integrally with the adjustment member 4, the screw receiving portion 6
As shown in FIG. 4 (b), by forming a hexagonal portion 6a on the outer peripheral surface at the leading edge thereof, the wall surface 2 of the adjusting member 4 is formed.
It is possible to tighten with a tool such as a pipe wrench at the time of mounting on the adjusting member 4, to prevent the occurrence of play and a decrease in crimping force due to insufficient tightening of the adjusting member 4, and to prevent the adjusting member 4 from being damaged or soiled. When the screw 5 is screwed in from the front side of the guardrail 1 by screwing the fixing screw 5 from the front side of the guardrail 1, the screw receiving part 6 can be easily traversed. . In addition, although the case where it applied to the wall surface 2 in which the mortar surface layer 31 was formed on the surface of the concrete base 30 was shown above, as shown in FIG. A male screw part 25 having a threaded part 32 at one end and an adjusting member 3 installed on the wall surface 2 side at a protruding part at the other end.
5 (b), the adjusting member 4 may be fixed by a wood screw 33. In this case, the insertion hole 34 of the wood screw 33 is
A hole for preventing rotation during processing of the female screw portion 19 of the adjusting member 4 can be used. Further, as shown in FIGS. 6 and 7, a board anchor 16 that holds the board material 35 between the bulging portion 36 and the nut 37 is used for the wall surface 2 made of the board material 35 such as a plaster board. Alternatively, an anchor 16 having a locking piece 38 to the back surface of the board material 35 may be used.

Since it is installed by being screwed into the screw receiving portion to be fixed, it is not necessary to separately fix each adjusting member to a wall surface or an adherend, thereby reducing the number of work steps and improving workability. In addition, height adjustment can be simplified. In addition, since the installation work on the wall surface of the adherend is unified in the direction with respect to the wall surface, the installation workability can be improved. Further, since the fixing screw is inserted into the pair of adjusting members and is not exposed to the outside, it is possible to prevent play or looseness due to an external factor.
