Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention mainly relates to a mounting device for a horizontal member in a handrail.

[Technical background of the invention and its problems]

As is well known, in the case of handrails in which horizontal members such as caps and crosspieces are attached between metal supports, the arms of the connector are inserted into the end surface of the horizontal member, and after fixing this with screws, the connection is made. The base of the tool was either inserted into the support and locked, or fixed with screws. In addition, when the support is made of concrete, a metal fitting is buried in the concrete support or the metal fitting is driven into the concrete support later, and the connecting tool is attached using this metal fitting. Regardless of the mounting method, there is a gap between the support and the horizontal member due to installation error, and the connecting tool is exposed through the gap, and rainwater can enter the mounting part through the gap. It also had the disadvantage of corroding the mounting part.

[Purpose of invention]

The purpose of this invention is therefore to conceal the mounting portions of the struts and the horizontal members by means of a cover that is threaded onto the connector, thereby alleviating the drawbacks of the prior art.

[Summary of the idea]

The horizontal member mounting device according to the present invention consists of a connector that has a cylindrical part with a male thread on the front part of the pedestal that is fixed to the support, and a male thread of the connector on the rear part of the cylindrical body that can be inserted into the horizontal member. The horizontal member is held between the column and the support by a cover provided with a female thread that is screwed together, and the cover that is screwed onto the male thread is fixed to the horizontal member using a locking screw.

[Example of idea]

Hereinafter, the horizontal member mounting device according to the present invention will be explained based on the drawings of the embodiments. Reference numeral 1 indicates a support that constitutes a handrail, shelf, etc., and the support 1 is formed of a hollow metal member or made of concrete. ing. 2 is a horizontal member installed between pillars 1 and 1'; horizontal member 2
is cylindrical or approximately cylindrical. Reference numeral 3 denotes a connector to be attached to the support column 1, and the connector 3 has a cylindrical portion 5 approximately equal to the outside diameter R of the horizontal member 2 on the front part of the pedestal 4 that comes into contact with the support column 1.
The cylindrical portion 5 has a male thread 15 on its outer periphery, and the pedestal 4 has a through hole 14.
4' to the support 1 with bolts or screws. Specifically, the bolt B is attached to the anchor A buried in the support 1 through the through hole 14 of the pedestal 4.
or by driving a concrete pin P into the support column 1 through the through hole 14 to fix it. metal support 1
In the case of
Screw in and secure. 6 is the male screw 15 of the connector 3
The cover 6 is longer than the protruding dimension l of the cylindrical part of the connector 3 and has an outer diameter R of the horizontal member 2 so that it can be fitted into the horizontal member 2.
A connecting tool 3 is attached to the rear inner circumference of the cylindrical body 7, which is one size larger than the
A female screw 17 is provided to be screwed into the male screw 15 of the cylindrical body 7, and a locking screw 8 is screwably provided at the front of the cylinder body 7.

Since the horizontal member mounting device in this case has the above structure, the horizontal member 2 is attached between the concrete columns 1 and 1'.
When installing, anchors A should be buried in advance at the horizontal member attachment positions of columns 1 and 1', or anchors A should be driven into concrete columns 1 and 1' later, and this anchor A should be used to attach connector 3 first. Install.

That is, the pedestal 4 of the connector 3 is brought into contact with the support 1, and the bolt B is inserted from the pedestal through hole 14 toward the anchor A.
are screwed in to firmly fix the connector 3 to the supports 1 and 1'. Next, insert the cover 6 into the horizontal member 2 from one end, turn the cover 6 toward the cylindrical part 5 of the connector 3, rotate the cover 6, and insert the female screw 17 provided at the rear of the connector 3 into the cylindrical part 5 of the connector. After screwing the cover 6 into the male screw 15 and completely screwing it into contact with the pedestal 4 or support 1, the cover 6' is fitted onto the horizontal member 2 from the other end, and this cover 6' is also screwed in the same manner as described above. It is screwed into the male screw 15 of the connector 3 by means of the above-mentioned means. Since the covers 6 and 6' screwed onto the cylindrical portion 5 of the connector 3 are longer than the protruding dimension l of the cylindrical portion, the front portion of the cover cylindrical body 7 screwed onto the connector 3 is forward of the cylindrical portion 5. The cross member 2 protrudes from the cover 6 and supports the end of the cross member 2 inserted into the cover 6. The covers 6, 6' to be fitted onto the horizontal member 2 are connected to the cylindrical portion 5 of the connector 3.
After deeply screwing into the covers 6, 6' and supporting the horizontal member 2 in a horizontal state, screw the locking screws 8 provided on the covers 6, 6' until they come into pressure contact with the horizontal member 2, Fix the covers 6, 6' and the horizontal member 2,
Rotation of the covers 6, 6' and the horizontal member 2 is made impossible.
When installing the connector 3 using a concrete pin P, after the pedestal 4 of the connector 3 is brought into contact with the support 1, the concrete pin P is driven into the support 1 through the through hole 14 of the pedestal 4, and the connection is completed. Fix tool 3.
When attaching the connector 3 to the metal support 1, the pedestal 4 of the connector 3 is brought into contact with the support 1, and screws S are screwed into the support 1 through the through hole 14 of the pedestal 4 to fix it.

It should be noted that the horizontal member mounting device according to the present invention is not limited to the above embodiment, and for example, the horizontal member mounting device is not limited to the above embodiment.
After attaching the connector 3 to the horizontal member 2, insert the two covers 6 and 6' facing each other into the horizontal member 2, align the horizontal member 2 with the mounting position of the connector 3, and then insert the two covers 6 and 6' into the horizontal member 2. Not only can the covers 6 and 6' be screwed one by one onto the cylindrical part 5 of the connector 3 and fixed unrotatably with the locking screw 8, but also After omitting the male screw 15 provided and the female screw 17 provided on the cover 6, and fitting the cylindrical body 7 of the cover 6 to the outer periphery of the connector cylindrical portion 5, the covers 6, 6' are rotated with the locking screw 8. Almost the same purpose can be achieved by fixing the device immovably. Also, a means for attaching the connector 3 to the support column 1, a means for fitting and preventing rotation of the cover 6,
The shapes and structures thereof can be changed as appropriate as long as they do not go against the gist of the present invention.

[Effect of idea]

Therefore, the horizontal member attachment device according to the present invention can directly fix the connector to the column, so the connector can be stably and accurately attached to the column in no time, and the cover can be fixed to the column directly. The female screw provided at the rear of the connector is screwed into the male screw of the cylindrical part that protrudes from the base of the connector, and is fixed with a locking screw, so there is no space between the horizontal member and the connector. Even if there is a gap, it is hidden by the cover and cannot be seen from the outside. As a result, the horizontal member can be installed between the pillars in an attractive manner, and rainwater will not enter between the horizontal member mounting portions and cause corrosion. In addition, the connector can be easily and strongly fixed, and it is extremely easy to insert the cover and fix it with a locking screw.This design is suitable not only for installing horizontal members on handrails, but also for horizontal installation on shelves, fences, hedges, etc. It has features that can be applied to the installation of members, and has a significant practical effect in improving the efficiency of installing horizontal members.
