TECHNICAL FIELD The present invention relates to a mounting pin with a washer for repairing outer wall tiles.

[0002]

2. Description of the Related Art Many buildings such as recent buildings and houses have a tiled outer wall. With the passage of time after the completion of the construction of these buildings, as shown in FIG. 8, a gap 26, a so-called interlayer float, is formed between the outer wall tile 23 and the mortar layer 24 and between the mortar layer 24 and the concrete layer 25. As a result, the outer wall tile 23 may come off. Therefore, repair work is performed for the purpose of preventing the outer wall tiles 23 from coming off. In the conventional method, as shown in FIGS. 9 and 10, the outer wall tiles 23, the mortar layer 24, and the concrete layer 25 are drilled in this order. The drill hole 27 is cut, a metal anchor 28 is inserted into the drill hole 27, and a flange 29 provided on the outer periphery of the inlet 28 'of the anchor 28 is expanded on the surface of the outer wall tile 23 from the drill hole 27 and cut. The epoxy resin 32 is injected from the inlet 28 ′ of the anchor 28 by the resin injector 31 while being pressed against the hole 30 with or without the washer made of a soft material, and both ends of the anchor 28 are inserted. After filling the gap 26 with the epoxy resin 32 through the opening 33 that opens to the surface, a waste cloth or the like is pushed into the inlet 28 'of the anchor 28, and finally, the surface is covered with the outer wall tile. There is a method to fill in the combined putty and mortar to the third color.

[0003]

[Problems to be Solved by the Invention] However, in this method, since the putty and the mortar start to harden immediately when they are kneaded, the color matching with the outer wall tile 23 cannot be performed unless the outer wall tile 23 is in the actual condition. If there are multiple colors, the task is extremely difficult. In order to solve this problem, instead of using putty or mortar, as shown in FIGS. 11 and 12, a bifurcated pin 34, 34, and a washer 35 fitted to the outer diameter of the inlet portion of the anchor 28 are made of brass or the like. It is integrally molded with a metal that does not rust, and the surface of the washer 35 is colored in advance at the factory with a color that matches the color of the outer wall tile 23. During repair work, the tips of the pins 34, 34 are fingertips 36, 36. The construction method was adopted by simply inserting one after another into the inlet 28 'of the anchor 28 while purging. However, the outer wall tile 23, the mortar layer 24, and the concrete layer 25 are sequentially drilled by a drill hole 27, which is not necessarily perpendicular to the surface of the outer wall tile 23. For example, a worker is higher than his eye level. When the drill hole 27 is cut from the outer wall tile 23 located at the position, the obliquely upward drill hole 27 is easily cut as shown in FIG. Therefore, in the above-mentioned construction method, the washer 35 integrated with the pins 34, 34 is inserted with the washers 35 tilted with respect to the surface of the outer wall tile 23, which is not only unsightly to look at but also tilts. As a result, dirt 38 accumulates on the concave portion 37, which causes a new problem such as dirt on the outer wall surface. The present invention is to provide an outer wall tile-equipped washer mounting pin for rehabilitating outer wall tiles, which can solve the problems in the above-mentioned conventional methods by connecting the washer part to the rear end of the pin body so as to swing. It is intended.

[0004]

Means for Solving the Problems To achieve the above object, the present invention provides an outer wall tile, a mortar layer, and a concrete layer in this order, or a joint portion between the outer wall tile and the outer wall tile, and the mortar layer. In a mounting pin with a washer that can be inserted into the drill holes drilled in the order of the concrete layer and then inserted into the entrance of the metal anchor that can be injected with epoxy resin, the pin body is chemically resistant. The pin body is formed of a resin that is also excellent in weather resistance and has a spherical shape with a concave part that is conically inclined from the end face and a narrow inlet at the deepest part of this concave part. The washer is made of metal that does not rust, and the tip of the connecting shaft that stands upright from the center of the washer is provided with a spherical shaft that rotates while being in pressure contact with the bearing. ， This shaft is narrowed above The washer is connected to the rear end of the pin body so that it can be swung by forcefully fitting it into the bearing hole from the inlet. In the surface mounted pin with washer for outer wall tile repair described in the above item, the pin body is divided into two parts from the front end to the rear end of the cylindrical main body. The main body is characterized by having ribs projecting in the axial direction of the main body on both side surfaces of a portion of the main body divided by the slit portion.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The pin body to be inserted into the entrance of the anchor is molded with a resin having excellent chemical resistance such as solvent of epoxy resin injected into the anchor and also having weather resistance, for example, nylon or polypropylene. . This pin body has a slit part that bisects the body from the front end to the rear end of the cylindrical body, and on both side surfaces of the part of the body divided by the slit part, It has a rib protruding in the axial direction of the main body, and at the rear end of the main body, there is a recess that is conically inclined from the end face, and a spherical bearing hole that has a narrow inlet at the deepest part of this recess. Molded to have. The washer is made of metal that does not rust, for example, brass. At the tip of the connecting shaft that stands upright from the center of the washer, there is formed a spherical shaft that rotates while pressing against the bearing hole. The washer is swingably connected to the rear end of the pin body by forcibly fitting the shaft into the bearing hole through the narrow inlet. The surface of the washer is colored in the same color as the color of the outer wall tile or the joint.

[0006]

[Embodiment] An embodiment of the present invention will be described below with reference to FIGS. 1 to 7. In FIG. 1, 1 is a pin body to be inserted into the entrance of an anchor. Has a slit portion 4 that divides the main body 2 into two parts from its tip toward the rear end of the main body 2, and on both sides of the portion of the main body 2 divided by the slit portion 4, A spherical bearing having axially projecting ribs 5 and 5, a rear end portion of the main body 2 having a concave portion 6 conically inclined from the end surface and a narrow inlet 7 at the deepest portion of the concave portion 6. It is made of nylon or polypropylene so as to have holes 8.

This coloring is performed, for example, by painting a paint.

As shown in FIG. 2, the shaft body 12 of the washer portion 9 is forcibly fitted into the bearing hole 8 from the narrow inlet 7 provided at the rear end portion of the pin main body 1, so that the washer portion 9 As shown in FIGS. 3 and 4, the pin body 1 is connected to the rear end of the pin body 1 so that the pin body 1 can be swung. The inclination angle of the recess 6 is designed so that the washer 9 can be swung while the washer 9 is inclined up to 45 degrees.

Next, a description will be given of a usage example of the outer wall tile-equipped washer-equipped pin having the above-described structure. As shown in FIG. 5, the outer wall tile 13 is drilled in the order of the mortar layer 14 and the concrete layer 15 by a drill. When the hole 16 is, for example, obliquely upward, the anchor 17 is inserted into the drill hole 16, and the flange 19 provided on the outer periphery of the inlet 18 of the anchor 17 is attached to the surface of the outer wall tile 13 from the drill hole 16. After the epoxy resin (not shown in FIG. 5) is injected from the inlet 18 of the anchor 17 while being pressed against the hole 20 that has been expanded and cut with or without a washer made of a flexible material, the inlet 18 of the anchor 17 is inserted. Insert the pin body 1 of the washer-equipped surface mounting pin according to the present invention into the device. At the time of this insertion, the ribs 5 and 5 come into contact with the inner wall of the anchor 17 to press the slit portion 4, and at the same time, a repulsive force against the pressing of the slit portion 4 acts on the ribs 5 and 5 to push the ribs 5 and 5. Since the pin body 1 is pressed against the inner wall of the anchor 17, the pin body 1 is supported so as not to easily come off the anchor 17.
