Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a mounting bracket for a handrail support provided on a building balcony or the like.

[Conventional technology]

Handrails, which are generally attached to the periphery of buildings such as balconies and roof tops, are constructed by installing anchor plates with relatively short pillars erected on a concrete foundation for water return, with the tops of the pillars protruding from the concrete foundation at predetermined intervals. The handrails are installed on balconies, etc. by fixing the lower ends of the pillars that make up the handrail on the protruding parts of the pillars, but recently the concrete foundations to which the pillars are attached are called "ALC". There are quite a lot of cases made of lightweight foamed concrete, which has relatively low strength.

As mentioned above, when handrail columns are attached to a concrete foundation made of lightweight foamed concrete, the strength of the foundation is relatively weak, and if a large load is applied to one column for some reason, that part will be destroyed and a large amount of damage will be caused. There is a risk that it may lead to an accident, and as a result various reinforcement works are required, which increases construction costs.Also, there is a risk that the base of the support will rust and its strength will deteriorate due to rainwater entering through the support. be.

In addition, when fixing the anchor plate to the concrete foundation, its position is determined in advance and the position is fixed after fixing, so if there is an error in the size of the handrail itself, it cannot be corrected. There are many practical problems, such as the need for re-construction in some cases.

Therefore, the applicant has developed a handrail support mounting device that can easily and easily attach a handrail support without requiring any special work on the concrete foundation.

Its structure consists of an anchor rail made of a long member with a groove-shaped cross section mounted on a waist wall installed at the periphery of a concrete foundation that makes up a balcony, etc., and a predetermined interval is placed on the anchor rail. A plurality of support members are fitted and abutted, each having side plates on both sides with elongated holes in the longitudinal direction, and on the upper surface of which a support member to be inserted into the support of the handrail is attached so as to be movable in the front and rear direction, Insert a bolt from one side plate of each support member to the other side plate through the anchor rail and waist wall, adjust the longitudinal mounting position using the elongated hole, and then tighten with a nut. While integrally fixing the support member, a cap board having a through hole into which the support member is inserted is superimposed and fixed on the top surface of the support member, and a handrail post is externally fitted and fixed to the support material protruding from the top surface of the cap board, The purpose is to erect a handrail on the waist wall.

[Problem that the invention attempts to solve]

However, the support member in the above-mentioned handrail post mounting device is simply a support member that is inserted into the handrail post and is movably attached to the top surface in the front and back direction, so the strength of the support member itself is still insufficient. I can't say it's sufficient.

[Means for solving problems]

Therefore, this invention aims to provide a safe mounting bracket that further improves the overall strength of the handrail support mounting device. An anchor rail consisting of a long member with a groove-shaped cross section is covered with a mounting bracket for supporting the handrail column at a predetermined interval on the anchor rail, and is integrally attached to the waist wall and the anchor rail with bolts. In the handrail support mounting device for tightening and fixing, the mounting bracket is constituted by a cross-sectional groove-shaped member in which side plates are integrally connected to the front and rear side edges of a horizontal board that comes into contact with the top surface of the anchor rail, and each of the side plates is Each mounting bracket is provided with a long hole that allows it to be moved in the left and right direction, and on the horizontal board, a plate member with a support member that engages and holds the handrail support column erected and fixed is superimposed on the horizontal board so that it can be moved freely only in the front and back direction. It is characterized in that it is configured to hold.

[Effect]

5b are provided with elongated holes 6 that allow the mounting fittings 2 to be moved in the left-right direction, and on the horizontal substrate 5a is a plate member 8 having a supporting member 10 that engages and holds a handrail post 14 erected and fixed in the center thereof. Since it is constructed by overlapping and holding together so that it can move freely only in the front and back direction, the anchor rail 3 made of a long member is first attached to the waist wall 2 that is erected at the peripheral edge of the concrete foundation 1 that makes up the balcony etc. Then, the mounting brackets 5 of this invention were sequentially fitted and placed on the anchor rail 3 in accordance with the installation interval of the handrail supports 14, and the mounting brackets 5 were installed on one side plate 5b of the mounting brackets 5. An anchor bolt 17 is inserted from the long hole 6 toward the long hole 6 formed in the other side plate 5b corresponding to the long hole 6.
is inserted through the anchor rail 3 and the waist wall 2, and is tightened with a nut 18 to integrally fix the anchor rail 3 and the mounting bracket 5 to the waist wall 2. However, for example, depending on the finished dimensions of the foundation itself, etc. If there is some error in the mounting position of the mounting bracket 5, the mounting position is adjusted by moving the mounting bracket 5 in the longitudinal direction of the anchor rail 3, that is, in the left-right direction using the elongated hole 6.

Then, attach the mounting bracket 5 via the anchor rail 3.
After fixing the cap on the waist wall 2, the cap 15 is brought into contact with the mounting bracket 5 as shown in FIG.
5. A support member 10 that is engaged and held by the mounting bracket 5 is made to protrude from the upper surface.

This support member 10 has approximately the same internal shape as the handrail post 14, and is integrally erected and fixed to a plate member 8 on the horizontal base plate 5a of the mounting bracket 5, and this plate member 8 has an elongated hole 9 engages with the shaft rod 7 erected on the horizontal base plate 5a, making the plate member 8 movable only in the front-back direction, so when an error occurs between the mounting position of the handrail support and the handrail support due to the finished dimensions of the frame, etc. Loosen each nut 13,
After moving the plate member 8 in the front-rear direction along the long hole 9 and adjusting it to the optimal position for installation,
The nut 13 is tightened again to fix the plate member 8 on the horizontal substrate 5a.

After that, the handrail post 14 is fitted onto the supporting member 10 that protrudes from the surface of the cap 15, and both are secured with bolts 1.
9, and after constructing upper and lower horizontal bars between each handrail support 14, connect a plurality of vertical bars between the horizontal bars, and cover the upper horizontal bars with an upper cap to complete the handrail. It is something to be assembled.
