JP 2002-54279 A

The present invention is manufactured by assembling a pair of anchor members and a reinforcing member for reinforcing the anchor members, and can be applied to various handrail struts having different sizes. Prop fixtures are provided. The present post support fixture is mainly used to fix a handrail support installed on a veranda or the like.

The present post support fixture includes two rod-shaped anchor members and reinforcing members for reinforcing these anchor members. These anchor members are each formed with a groove having a T-shape in plan view from one end to the other end. Reinforcing members that reinforce these anchor members are each formed in a T shape in plan view, and as a whole H shape in plan view, and in each of the T-shaped grooves facing the anchor bolt, The T-shaped both ends of the reinforcing member are inserted and assembled.

The dimensions of the T-shaped groove of the anchor member and the T-shaped end of the reinforcing member are the same. Therefore, it is possible to assemble a post fixing bracket that fits any size handrail post (hereinafter also referred to as a “post”) by appropriately adopting the widthwise dimension of the main body of the reinforcing member. Moreover, the length dimension of an anchor member can also employ | adopt an appropriate thing according to the size of the support | pillar used for a handrail. Furthermore, the handrail support strength can be increased by increasing the diameter of the anchor member and / or increasing the number of reinforcing members.

The side in contact with the inner surface of the handrail strut of each of the above-mentioned pair of anchor members constituting the handrail strut fixing bracket is formed as a rectangular flat surface from one end to the other end. Accordingly, the above-described surface of the post fixing bracket and the inner surface of the handrail post are in close contact with each other without any gap, and stable installation is possible. Further, a groove having a triangular cross-sectional shape is formed at the center in the longitudinal direction of this surface. The post fixing bracket and the handrail post are fixed using screws. For this reason, this post fixing bracket is provided with a screw tap screw, and the handrail post is provided with a screw through hole. When the pilot hole is installed by the drill for providing the tap screw, the tip of the drill usually comes to the apex of the triangular groove, so that it can be accurately and easily provided at the center in the longitudinal direction of the surface. Therefore, even if it is not an expert in the installation construction site of the handrail support | pillar, a tap screw can be easily set correctly and the screw installation external appearance is also excellent.

A concave groove is formed at the center in the longitudinal direction from one end of the outer surface of both ends of the reinforcing member to the other end. For this reason, when inserting the T-shaped end portion of the reinforcing member into the T-shaped groove provided in the anchor member, the biting can be smoothly inserted. Further, an adhesive can be press-fitted into the gap formed by the concave groove and the anchor member, and when the anchor member and the reinforcing member are fixed with the adhesive, the adhesive can be easily and reliably fixed.

Both the anchor member and the reinforcing member constituting the support fixture are made of the same material, and are made of aluminum or an aluminum alloy (hereinafter collectively referred to as “aluminum”). Aluminum is light and easy to handle, and has a lower unit price than stainless steel. Aluminum can be produced with good dimensional accuracy both in casting and in cutting. Accordingly, since the dimensional accuracy of the anchor member and the reinforcing member is large, the post fixing bracket can be easily assembled. Furthermore, the main column fixing bracket can be smoothly inserted into the handrail column. Furthermore, since there is no distortion due to thermal expansion between the assembled members, even when the anchor member and the reinforcing member are assembled and fixed using an adhesive, there is little deterioration over time.

The present post support fixture has a small number of parts, and is simple in structure and easy to manufacture. For this reason, the manufacturing cost can be kept low. By appropriately combining the anchor member and the reinforcing member constituting the fixing bracket, it is possible to easily adapt to various sizes of support columns. The fixing strength is ensured by increasing the diameter of the anchor member and increasing the number of reinforcing members.

Further, the side of the pair of anchor members that make up the support bracket is in contact with the inner surface of the handrail support post is formed as a rectangular flat surface from one end to the other end. The surface formed on the inner surface of the handrail post and the inner surface of the handrail support come into contact with each other.

Furthermore, since a groove having a triangular cross-sectional shape is provided in the center of the surface formed on the anchor member, this groove is provided when a screw tap screw used for fixing the handrail support post to the support post fixing bracket is provided. Since the cross-sectional shape of this is a triangle, it can be easily set accurately at the center of the groove.

In addition, the material of the anchor member and the reinforcing member constituting the post fixing bracket are both the same material, and when made of aluminum, it is lightweight, easy to handle, low in production cost, and has high dimensional accuracy. Even when the adhesive is fixed with an adhesive, there is almost no distortion due to thermal expansion between the assembled members, so that the mounting strength of the column fixing bracket is less likely to deteriorate over time.

The present application post fixing bracket includes a pair of rod-shaped anchor members and a reinforcing member for reinforcing the anchor members. This anchor member can change a length dimension suitably. In addition, reinforcing members having different width dimensions are prepared in advance and selected from these, or are manufactured from a rectangular plate metal by grinding or the like. When installing the handrail installation work, determine the length of the anchor member so that it matches the size of the handrail strut, and select the handrail strut size from among the reinforcing members with different width dimensions. A suitable one is selected or manufactured, and the anchor member and the reinforcing member are assembled and used.

In this pair of rod-shaped anchor members, a groove 21 having a T shape in plan view is formed from one end to the other end (see FIGS. 1 and 2). Further, in the reinforcing member for reinforcing the anchor member, both end portions 32 in the width direction of the reinforcing member main body are formed in a T shape, and the entire plan view has an H shape (see FIG. 2). . The fixing bracket is assembled by inserting both ends of the T-shape of the reinforcing member into the opposing T-shaped grooves of the pair of anchor members.

In the following, the present strut fixing bracket will be described in detail with reference to the drawings. These drawings are schematically drawn for explaining the present invention, and the present invention is not limited to these drawings. In addition, common reference numerals (numbers) of members and the like are used in common. Further, the reference numerals of members and the like that are apparent from the drawings are omitted.

FIG. 1 is a perspective view of the post fixing bracket 1 of the present application. In FIG. 1, it consists of two rod-shaped anchor members 2 and two reinforcing members 3. Depending on the size of the handrail column to be fixed, the length of the anchor member 2 can be reduced to make the reinforcing member 3 one. Further, depending on the size of the handrail support column to be fixed, the length of the anchor member 2 can be increased so that the number of reinforcing members 3 is three or more.

The length of the anchor member 2 is usually 300 mm to 600 mm. This is because if it is less than 300 mm, the handrail support strength may be insufficient with respect to the lateral moment of the handrail support, and the anchor member 2 exceeding 600 mm is not normally required. The cross section of the anchor member 2 is usually inscribed in a circle having a diameter of 15 mm to 18 mm. This is because if the ring is inscribed in a circle having a diameter of less than 15 mm, the mounting strength may be insufficient, and if it is inscribed in a circle exceeding 18 mm, the anchor member 2 may not be inserted into the gap between the reinforcing bars of the frame.

The dimension L (refer FIG. 6) of the width direction of the reinforcement member 3 is 35 mm-75 mm. This is because the size of the handrail support for a veranda that is normally used is in the above range. The thickness is 3 mm to 5 mm. If the thickness is less than 3 mm, the strength may be insufficient. If the thickness exceeds 5 mm, the strength is excessive and the production cost increases. The reinforcing member 3 is prepared and prepared in advance within the above range. The size of the handrail support column that is normally used is almost fixed, and it is not necessary to prepare many kinds of reinforcing members. Since the structure of the reinforcing member is simple, the manufacturing cost can be kept low. In addition, when installing a handrail support column of a size not normally used, it can be easily obtained by grinding the aluminum plate so as to conform to this size.

FIG. 2 is an explanatory view of assembly of the post fixing bracket 1 of the present application. Fig.2 (a) is explanatory drawing before an assembly. The reinforcing member 3 includes a reinforcing member main body 31 and T-shaped reinforcing member end portions 32 in plan view at both ends in the width direction of the reinforcing member main body 31. The reinforcing member end portion 32 is inserted into the groove 21 having a T-shaped planar shape formed on the rod-shaped anchor member 2. The T-shaped groove 21 is formed from one end of the anchor member 2 to the other end as shown in the figure. The end portion 32 of the T-shaped reinforcing member main body 3 and the groove 21 of the T-shaped anchor member 2 are shapes into which both are inserted, and do not necessarily mean an accurate T-shape.

FIG. 2 (b) shows the present post fixing bracket 1 completed by fitting the end portions of the reinforcing members 3 into the grooves 21 of the pair of anchor members 2. As described above, the number and size of the reinforcing members to be inserted vary depending on the size of the handrail strut to be constructed. The inserted reinforcing member 3 and anchor member 2 are fixed with an adhesive, caulking, pins, screws and the like. Of these, fixing with an adhesive is particularly preferable. This is because the fixing method using an adhesive is simpler than other fixing methods, and the fixing strength is not inferior to other methods. The material of this adhesive is not particularly limited. Conventionally used epoxy resins and urethane resins are preferably used. This support fixture 1 has a simple structure and is assembled by fitting the anchor member 2 and the reinforcing member 3, so that the dimensions are always constant and welding is not required, so that even a non-expert can easily manufacture the result. As an inexpensive one.

FIG. 3 is a front view of the post fixing bracket 1 of the present application. The embedded portion 22 of the anchor member 2 in the figure is a portion embedded in a hole drilled for embedding in the casing. This portion is embedded in the hole and fixed with a fixing filler. The shape of the housing embedded portion 22 is not particularly limited, but it is preferable to increase the fixing strength by providing irregularities or the like to increase the contact area with the above-described fixing filler. In the figure, a male screw-shaped groove is provided to increase the fixing strength, but the present invention is not limited to this male screw-shaped groove.

FIG. 4 is a plan view of the post support fixture 1 of the present application. FIG. 5 is a side view of the present post fixing bracket 1. As long as the anchor member 2 has a rod-like shape and a groove into which the T-shaped end of the reinforcing member 3 can be inserted, the shape of the other part is not particularly limited, but preferably a pair of anchors. The side of the member 2 that contacts the inner surface 41 (see FIG. 7) of the handrail strut is flat from one end to the other end so that the inner surface 41 of the handrail strut and the anchor member 3 are in contact with each other. A smooth surface 23 is preferably formed. When the surface 23 is provided, the handrail support 4 can be fixed more firmly and stably because the support fixture 1 and the inner surface 41 of the handrail support are in close contact with each other.

It is preferable to provide a groove 24 having a triangular cross section (planar shape) from one end to the other end of the surface 23 at the center in the longitudinal direction of the surface 23 of the anchor member 2 described above. This is because it is easy to set up the tap screw of the screw 5 for fixing the column to the column fixing bracket 1 (see FIGS. 7 and 8). When drilling a pilot hole for raising a tap screw, the tip of the drill usually comes at the apex of the groove triangle. Therefore, this pilot hole can be provided in the central part of the surface 23 with which the anchor member 2 is provided. For this reason, even if it is not an expert, a tap screw can be stood up correctly and easily in the center part of the surface 23. FIG. As a result, the screw when the support is fixedly fixed fits in the support and has an excellent aesthetic appearance.

FIG. 5 is a side view of the post fixing bracket 1 of the present application. According to this figure, the surface 23 provided on the anchor member 2 constituting the post fixing bracket 1 of the present application and the groove 24 having a triangular cross section are also provided in the portion of the embedded portion 22. 23 and the groove 24 may not be provided.
FIG. 6 is a plan view of the reinforcing member. The reinforcing member 3 is not particularly limited to other portions of the both end portions as long as both ends can be fitted into the grooves 21 provided in the pair of anchor members 2. The groove 34 is preferably formed. FIG. 6A shows a case where the surface 33 of the end portion 32 of the reinforcing member 3 is a flat surface. FIG. 6B is a view when a concave groove 34 is provided on the surface 33 of the end 32 of the reinforcing member 3. When the concave groove 34 is provided, the reinforcing member 3 can be smoothly inserted into the anchor member 2. Further, after inserting the reinforcing member 3 into the anchor member 2, an adhesive is press-fitted from the gap 34 (see FIG. 4) between the groove 34 and the anchor member 2, so that the anchor member 2 and the reinforcing member 3 can be easily and reliably attached. It can be fixed.

FIG. 7 is a partial cross-sectional explanatory diagram for fixing the support column. FIG. 7A is an explanatory diagram in the case of fixing a relatively small support column. FIG. 7 is an explanatory diagram for fixing a standard support column of (b) size. FIG. 7 is an explanatory diagram in the case of fixing a support column having a large size (c). It can be seen that, regardless of the size of the support column, it can be applied to any size only by changing the width dimension of the reinforcing member main body 31 of the reinforcing member 3 (the anchor member 2 can always be used in common). A pilot hole (not shown) for erecting a screw screw 51 for fixing a screw with a drill is usually provided with a pilot hole at an accurate position because the tip is guided to the apex of the groove 24 having a triangular cross section provided in the anchor member 2. For this reason, the tap screw can also be provided in a precise position. The handrail support column can be easily and accurately attached with a screw even at a handrail construction site.

The material of the present post fixing metal fitting 1 is not particularly limited, but a metal that does not corrode is preferable. Of these, stainless steel has been mainly used. Stainless steel is not easy to process such as cutting and grinding, is difficult to cast, and is more expensive than aluminum. In the present invention post fixing metal fitting which is another invention, both the anchor member 2 and the reinforcing member 3 are made of the same material, and the material thereof is aluminum or an alloy of aluminum. Aluminum (alloy) is easy to cast and process and has excellent dimensional accuracy in casting and processing. This anchor fixing bracket of the present application using an anchor member using aluminum and a reinforcing agent is excellent in dimensional accuracy (handrail) and can be inserted in close contact with the supporting pillar 4 smoothly. Aluminum is lighter and easier to handle than stainless steel. Aluminum has a high strength per unit weight and a specific strength more than twice that of stainless steel. Further, when both the anchor member 2 and the reinforcing member 3 are made of the same aluminum material, both have the same coefficient of thermal expansion, and even when fixed with an adhesive or the like, aging deterioration based on the difference in coefficient of thermal expansion is caused. Few.
