Description

[Detailed description of the invention] "Industrial application field" This invention relates to handrails that are attached to buildings.

"Prior Art and its Problems" Traditionally, handrails installed on balconies and the like are assembled from materials such as iron or stainless steel by welding and then attached to buildings.

For this reason, materials are cut in advance to predetermined dimensions according to installation conditions, subjected to processing such as welding, and then transported to the site for installation work.

Therefore, there are drawbacks that a design is required for each property, which is time-consuming and increases costs.

Furthermore, since the welded portion must be finished, there is also the disadvantage of increased costs.

``Means for Solving the Problems'' This invention provides a handrail structure that can be assembled without the need for welding. The configuration is, for example, made of extruded aluminum and has a U-shaped cross section, and is attached to the building body with the U-shaped convex surface facing upward. 1 a protruding piece and a Kasagi stand having an engaging protrusion on the convex side of the U-shaped cross section; A cap wood having an engaging piece that engages with the mating protrusion and a second protruding piece that protrudes inward at both ends of the U-shaped cross section and makes surface contact with the first protruding piece, and the first protruding piece and the second protruding piece. The connecting screw and
It consists of

According to this configuration, the installation work is completed in the assembly process of covering the Kasagi stand attached to the frame with the Kasa wood from above, and connecting the Kasagi stand and the protrusions formed on the Kasa wood with screws. .

Therefore, assembly can be carried out by simply cutting the cap board stand and the cap lumber to predetermined dimensions at the installation site. Further, since the cap board stand and the cap wood are connected using screws, work such as welding is not required. Furthermore, the screw is screwed into the lower surface of the inside of the cap wood toward the concave surface of the cap wood. As a result, the heads of the screws are not directly visible and a good-looking handrail can be obtained.

``Example'' Figure 1 shows an example of this invention. In the figure, 1 indicates a frame such as a wall surrounding the outer periphery of a balcony, for example. Attach the Kasagi stand 2 to the upper surface of the frame 1 with screws 3. As shown in Fig. 2, the Kasagi stand 2 is a long material such as an extruded aluminum section, and its cross section has an approximately U-shaped cross section as shown in Fig. 1. First protruding pieces 2A, 2 protruding outward
It has B. The concave portion 2C having a U-shaped cross section is placed over the body 1, and screws 3 are inserted from the convex surface 2D side to fix it to the body 1. Engagement protrusions 2E and 2F are provided on the convex side, that is, the upper surface, of the Kasagi stand 2 so as to protrude upward.

4 indicates Kasa wood. The cap wood 4 has a substantially U-shaped cross section like the cap board 2, and is made of a long material such as extruded aluminum, as shown in FIG. The inner width W of the cap wood 4 is selected to be slightly larger than the dimension connecting the outside of the first protruding pieces 2A and 2B of the Kasagi stand 2, and the entire Kasagi stand 2 including the first protruding pieces 2A and 2B is It is put on to cover.

On the inner wall surfaces on both sides of the cap wood 4, there are second walls facing inward.
Projecting pieces 4A and 4B are provided. By placing the concave surface 4C of the cap wood 4 over the convex surface 2D of the cap board stand 2, the second protrusions 4A, 4B are brought into surface contact with the first protrusions 2A, 2B. In the state where the surfaces are joined, the first protruding pieces 2A, 2B and the second protruding pieces 4A, 4B are screwed from below by screws 5.
are connected and the cap wood 4 is fixed to the upper surface of the cap board stand 2.

Engagement pieces 4E, 4F are provided on the concave surface 4C of the cap wood 4, and these engagement pieces 4E, 4F are engaged with the inner sides of the engagement protrusions 2E, 2F provided on the cap board stand 2. Further, the protruding lengths of the engaging protrusions 2E and 2F are selected so that their upper ends come into contact with the concave surface 4C of the cap wood 4.

(Operation and Effect of Example) According to the above-mentioned implementation structure, the Kasagi stand 2 and the Kasagi wood 4 are cut to desired dimensions, the Kasagi stand 2 is fixed to the frame 1 with the screws 3, and the Kasagi stand 2 is fixed to the frame 1 with the screws 3, and the Kasagi stand 2 and the Kasagi wood 4 are cut into the desired dimensions. The Kasagi stand 2 and the Kasa wood 4 are placed on the stand 2 by screws 5.
If you connect them, the installation work will be completed.

Therefore, the installation work can be completed in a short time. Furthermore, installation work can be easily carried out since large-scale construction work such as welding is not required.

Furthermore, by constructing the cap pedestal 2 and the cap 4 by extruded aluminum, the installation work can be carried out even more easily without the need for anti-rust coating. Further, since the engaging protrusions 2E, 2F and the engaging pieces 4E, 4F engage with each other, the cap pedestal 2 and the cap wood 4 increase their resistance against lateral forces, and can provide a strong handrail. Furthermore, the upper ends of the engaging protrusions 2E and 2F are the concave surfaces 4 of the cap wood 4.
Since it contacts C, it has a structure that is strong against forces from above.

"Modified Embodiment" FIG. 3 shows a modified embodiment of this invention. In this example, a case is shown in which a bar material 6 is provided on the upper surface 4D of the cap wood 4. The bar member 6 has a substantially rectangular cross section and can be constructed from an extruded aluminum member having a groove 6B on the lower surface 6A. The groove 6B has flanges 6C and 6D protruding inward on its open surface,
The head 7A of the bolt 7 is engaged with the flanges 6C and 6D, and the bolt 7 is attached to the cap wood 4.

Aggregate 8 is inserted between the bar material 6 and the cap wood 4. As shown in FIG. 4, the aggregate 8 can be an extruded rectangular cylindrical member. The bolts 7 pass through the aggregate 8 and engage with the cap wood 4, and the cap wood 4 and the bar material 6 are joined by tightening the nuts 7B.

With the bar material 6 attached to the cap wood 4,
is placed on the Kasagi stand 2, and the Kasagi stand 2 and the Kasagi wood 4 are connected with the screws 5 in the same manner as described above to complete the assembly.

Even when the bar material 6 is attached in this manner, the installation work can be easily performed. However, since the bolt 7 has a structure that penetrates the hollow part of the aggregate 8, the bolt is not visible from the outside. Furthermore, the head 7 of the bolt 7
Since the nuts A and 7B are not exposed to the outside, a good-looking handrail can be provided.

Figure 5 shows the parts used for the corners of the handrail according to this invention. This corner part 9 is formed of aluminum, and has insertion parts 9A and 9B at the ends that are shaped so that they can be inserted into the hollow parts of the cap wood 4 or the bar material 6. By inserting the handle into the cap wood 4 or the bar material 6, the corner part of the handrail can be made.

``Effects of the invention'' As described above, according to this invention, it is possible to provide a handrail that is easy to install and has a good appearance. It also has excellent strength and can provide a highly safe handrail.
Furthermore, since the construction is simple, it can be provided at low cost, and its effects are extremely large in practical use.
