JPH094165A - Horizontal muntin fixing member for handrail column and handrail using the fixing member - Google Patents

Abstract

PURPOSE: To facilitate mounting works by forming a pinching piece for fixation of a horizontal muntin in a single piece with a fixing member which secures the horizontal muntin to a handrail pillar, fitting the fixing member fast on the pillar, and then securing the horizontal mutin using screw, etc., while the pinching piece is interposed. CONSTITUTION: A horizontal muntin fixing member 1 is fitted on a square pillar, located, and fastened by inserting screw, etc., into a hole 4, and the horizontal muntin of the handrail is inserted to a horizontal muntin fixation part 3 consisting of pinching pieces and secured by driving screw, etc., into a hole 5. The shapes of the fixing member 1 and pinching pieces 3 should depend upon the contours of the pillar and the horizontal muntin inserted (for example, circular or in an arc of circle in the case of columnar form), and the surrounding part 2 is split into two segments so that they pinch the pillar. It is made practicable for mounting works to be all performed from outside the pillar. The pillar on which the fixing member 1 is mounted, may be of slide type consisting of double tubes so that the height of the handrail is adjustable. Thereby the handrail mounting works can be simplified.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a member for fixing a support of a handrail provided on a rooftop of a condominium of a building and a handrail using the member.

[0002]

2. Description of the Related Art As a conventional handrail, as shown in FIG. 12, a head tree 20, a plurality of pillars 21 attached to the lower surface of the head tree, a horizontal rail 22 connecting the lower parts of the pillars, and a head rail and a horizontal rail. A handrail including a lattice 23 formed by a vertical element provided between them is known. Generally, such handrails have a length of 6
It is a form in which the columns are provided at intervals of 1.2 m in m units, and if these units are connected according to the situation of the construction site, the handrail can be attached quickly and accurately.

As a construction method for that purpose, first, the position where the support is to be set is marked out on the handrail mounting surface of the floor to which the handrail is attached, a hole is opened at that position, and the lower end of the support is inserted into the hole to obtain an epoxy resin system. There is a method of fixing with a bond or the like. Other fixing methods include a method of welding the lower end of the pillar to an anchor member previously embedded in a hole of concrete and filling the hole with mortar, and a method of fixing the lower end of the pillar to concrete with bolts.

On the other hand, for a veranda or a passage formed on the roof of a building, a waterproof layer is first formed on the roof, and then concrete for protecting the waterproof layer is cast on the portion used as a veranda or the passage. It is common to provide handrails on the concrete part.

The handrail mounting method in this case is as follows: (a) A precast concrete member (PC member) having a hole at the center of about 15 cm in height after marking out the position where the handrail is to be placed before placing concrete. The method is to install the handrails at intervals between the handrails, insert the lower ends of the handrails into the holes of the PC member, and bury the mortar to provide the handrails. (B) A method in which after placing concrete, the handrails are marked out, holes are made in the concrete, and the columns of the handrails are inserted into the holes, and the columns are fixed with an epoxy resin bond or the like. (C) Before placing concrete, after marking out at the position where the handrail is to be installed, set the formwork and anchor for forming the insertion hole for the handrail post, and after placing the concrete, insert the handrail post into the hole, Welding to anchor and backfilling with mortar. Etc.

[0006]

However, since the rooftop portion requires rainwater drainage to have a water gradient up to the drainage drain, if a railing of a handrail is to be installed horizontally, it will hang from above the water to below the water gradient. The length of the handrail support must be changed. Since the water gradient needs to be at least about 1/100, the length of the handrail support column needs to change by about 10 cm at 10 m.

In such a case, in the conventional method (a), since the PC member has a height of about 15 cm as described above, the insertion length of the handrail support post into the hole can be adjusted to make the water gradient. On the other hand, since there is a considerable gap between the concrete floor surface and the horizontal rail of the handrail, it is necessary to provide an extra member at the bottom of the horizontal rail to prevent objects from rolling through and children from slipping through. In addition, there is a problem that a complicated work of installing the PC member and filling the mortar is involved. By the way, in order to prevent slipping through, it is necessary to make the gap between the concrete floor surface and the horizontal rail about 10 cm.

Further, in the above conventional methods (b) and (c), since the handrail support is directly inserted into the concrete floor surface, it is easy to suppress the gap between the concrete floor surface and the horizontal rail to about 10 cm, but the waterproof layer. Since the thickness of the concrete cast on the top is generally about 6 cm, it cannot be adjusted by the insertion length of the handrail support. for that reason,
(1) Measure the level of the post to be installed in advance and prepare by changing the length of the post one by one at the stage of handrail production, or (2) Produce a long post and attach it when installing. It was necessary to adjust while cutting on the spot. In the case of the above (1), there is a problem that the labor of the preliminary inspection and the manufacturing work are required, and in the case of the above (2), the cutting and the adjustment are troublesome and time-consuming.

As a means for solving such a problem, it is conceivable to provide a slide pillar which can be slidably inserted into the lower end inner surface of the handrail pillar, but in the conventional handrail, as shown in FIG. Since the head 26 of the rivet 25 for fixing the L-shaped angle member 24 for fixing the column to the supporting column 21 projects to the inner surface of the supporting column, a situation in which the sliding supporting column cannot be inserted occurs. It is also conceivable to insert the slide post without fixing the cross rail to the post and fix the cross rail to the post when positioning is completed. Since there is no member to resist distortion during installation work, the entire handrail is distorted, or the lattice part consisting of the vertical bar and the horizontal rail becomes swingable, causing collision with other parts and damage. There was an inconvenience.

The present invention has been made in order to solve the above-mentioned conventional problems, and it is an object of the present invention to provide a horizontal rail fixing member for a handrail support and a handrail using the horizontal rail fixing member, which enables quick and accurate construction. is there.

[0011]

Means for Solving the Problems The solution according to the present invention is a novel cross rail fixing member for a handrail support and a handrail using the same, which encloses the support of the handrail in a shape adapted to its outer shape. The gist of the present invention is a horizontal rail fixing member of a handrail pole, which is composed of a pillar surrounding portion fixed to a pillar and a horizontal rail fixing portion connected to and protruding from the pillar surrounding portion. A slide pillar having a pillar, which can be slidably inserted into each pillar inner surface, a pillar surrounding portion fixed to the pillar surrounded by a shape adapted to the outer shape of each pillar, and connected to the pillar surrounding portion and The gist is also a handrail including a horizontal rail fixing member of a handrail post having a protruding horizontal rail fixing portion.

A cross rail fixing member for a handrail support and a handrail using the same will be described below with reference to the accompanying drawings. FIG. 1 shows an example of a cross rail fixing member of a handrail strut of the present invention. The cross rail fixing member 1 is connected to the square pillar surrounding portion 2 and the surrounding portion 2 and is provided on both sides. It is composed of a horizontal rail fixing portion 3 formed of a protruding sandwiching piece. In this case, the inner diameter of the box-shaped portion 2 is the same as the outer diameter of the square column, so that the box-shaped portion 2 can freely slide on the column surface, and the hole 4 for mounting rivets, screws, etc. can be used to provide an appropriate position. It can be fixed to the column with.

The surrounding portion 2 is integrally provided with a horizontal rail fixing portion 3 consisting of a pair of sandwiching pieces. The spacing between the sandwiching pieces is the same as the outer diameter of the horizontal rail, and the horizontal rail ends are the same. Since the portion can be clamped from both sides, the horizontal rail can be fixed to the enclosing portion by using the hole 5. The cross rail fixing portions 3 are usually provided on both sides of the enclosing portion, but when the cross rail fixing portions 3 are attached to the columns of the handrail end, the cross rail fixing portion 3 on one side is unnecessary.

Needless to say, the shape of the enclosing portion 2 is the same as that of the pillar, and is determined depending on whether it is a prism or a cylinder. Further, the shape of the horizontal rail fixing portion is also determined according to the shape of the horizontal rail. For example, if the horizontal rail has a quadrangular cross section, it has a flat plate shape, and if it has a circular cross section, it has a curved surface shape corresponding thereto.

The enclosure 2 may be made of a metal such as aluminum, as long as it is strong enough to fix rivets or screws to the column and the cross rail.

Next, the handrail according to the present invention will be described. FIG. 2 is an explanatory view showing a horizontal rail fixing member of the present invention and a mounting state of a handrail using the horizontal rail fixing member, and FIG. 3 is a partial perspective view showing a state where the horizontal rail fixing member of the present invention is mounted on a column. Figure 2
As shown in FIG. 3, the handrail of the present invention includes a handrail support column 8, a slide support column 7 that can be slidably inserted into the inner surface of the support column 8.
A horizontal rail fixing member 1 having a pillar surrounding portion 2 fixed to the pillar 8 and surrounded by a shape adapted to the outer shape of the pillar 8 and a horizontal rail fixing portion 3 continuous with and protruding from the pillar surrounding portion 2. It is mainly composed of and. On top of the handrail support 8,
Is attached, and a lattice 13 constituted by a vertical element is provided between the headstock 10 and the horizontal rail 9. On the inner surface of the handrail support 8,
It has a slide pillar 7 which can be slid and inserted, and a rib 11 for holding a core material is provided on an inner wall of the pillar 7 and is fixed by a screw 12. In FIG. 2, only one of the handrail support columns 8 is shown, but normally, a plurality of units are constructed as a handrail.

A fixing member of the present invention and a method of constructing a handrail using the fixing member will be described. (1) Assemble a headstock, columns, cross rails, and a grid in advance at the factory. At this time, the surrounding portion 2 of the fixing member 1 is inserted into the column 8 on the column, and the horizontal beam fixing portion 3 is fixed to the horizontal beam 9 with rivets or the like. At this stage, the enclosure 2 and the column 8 are not fixed. (2) The handrail having the above-mentioned configuration is attached together with the core material 6 and the slide column 7 and carried to the site. (3) On the site, the mounting position of the support pillar is marked out, a hole is vertically formed at a predetermined position with a hammer drill or the like, an epoxy resin bond is injected into the hole, and then the core material 6 is inserted. (4) After fitting the slide column 7 into the core and fixing it with the screw 12, finely adjust to the correct position. (5) The handrail is suspended while the slide column 7 having been set is inserted into the column 8. (6) After adjusting the handrail headstock 10 to be horizontal, the slide column 7 and the encircling portion 2 of the fixing member 1 are fixed to the column 8 with rivets or the like in a temporarily held state, and the work is completed.

In the above-mentioned construction method, the core member 6 and the slide column 7 may be integrally manufactured in advance in a factory. This further simplifies the mounting work. In the case of the handrail attachment method for cutting and processing the support pillars on site, as described in the prior art, the core material 6 cannot be mounted on the support pillars in advance, and it is possible only when standardized as in the present invention.

Further, in the above-mentioned construction method, the reason why the enclosure 2 and the pillar 8 are not fixed during the factory manufacturing of the handrail is that when the slide pillar 7 is inserted into the pillar 8 on the spot if they are fixed with rivets or the like. This is because the rivet head protruding on the inner surface of the column 8 is an obstacle and the slide column 7 cannot be inserted. Then, even if the enclosure 2 is not fixed, the enclosure 2 is sandwiched by the enclosure 2 simply by inserting the enclosure 2 into the pillar 8. Therefore, the horizontal rail is substantially fixed to the pillar 8. The handrails will not be bent at the time of loading and mounting on the site, and the lattice part of the handrails will not swing to collide with other members and be damaged. It is also conceivable that the enclosing portion 2 is fixed to the handrail support column 8 by welding at the factory manufacturing stage. In this case, it is not necessary to fix the enclosing portion 2 to the support column 8 in the field, and the work is simplified.

As shown in FIG. 4, the slide column 7 is provided with ribs 11 for fixing the stainless core material 6.
The ribs 11 not only improve the bending rigidity of the slide column 7, but also the core member 6 is held on the inner wall of the slide column 7, preventing the core member 6 from wobbling. The effect is that it can be securely fixed. Thereby, when a horizontal load is applied to the entire handrail, it is possible to reliably resist the bending moment generated at the lower end of the handrail support column 8.

The size of the handrail support column 8 is usually 50 mm.
Although a square one is used, it may be appropriately selected depending on the scale and purpose of the building. The size of the slide column is usually such that it can slide within the inner diameter of the column, and a 45 mm square is usually used. Further, the width of the cross rail may be a width that can be received by the sandwiching piece, and is usually about 30 to 60 mm. For the lower end of the core material, one having a diameter of about 16 mm is usually used.

Next, another example of the fixing member according to the present invention will be described. As another example of the fixing member 1, first, FIG.
As shown in FIG. 1, unlike the configuration shown in FIG. 1 in which the horizontal rail is sandwiched, a corresponding one configured to insert the horizontal rail fixing portion 3 into the horizontal rail 9 may be used. In this case, the outer shape of the horizontal rail fixing portion may be a shape that matches the inner shape of the horizontal rail, and is fixed by the rivet 25 or the like. Also, as shown in FIG.
It is also possible to provide the horizontal rail fixing portion 3 projecting upward from both ends of the side portion of the enclosing portion 2, and to fix the horizontal rail inside the fixing portion 3 as the fixing member 1.

As shown in FIG. 7, a tongue portion 14 for receiving the horizontal rail may be provided as a horizontal rail fixing portion on the side of the enclosing portion 2, so that the tongue piece is located on the lower surface of the horizontal rail. Should be provided in. Although this tongue piece cannot be torn or extruded by a mold material, it is manufactured by welding the tongue piece or processing and bending the tongue piece.

Further, as shown in FIGS. 8 and 9, the pillar and the horizontal bar are formed by at least two members in which the horizontal bar fixing portion 3 is formed on the enclosing portion 2 having a U shape or a U shape according to the outer shape of the pillar. It may be sandwiched. In this case as well, the surrounding portion 2
The struts are riveted, and the horizontal rail fixing portion 3 and the horizontal rail are also riveted. Although FIG. 9 shows a fixing member to a circular strut, if the cross rail abutment portion 15 is formed flat, when the cross rail is joined to the circular strut, the end of the cross rail is processed into an arc shape. This is preferable because it does not need to be performed.

An example of mounting the horizontal rail fixing member of the present invention will be described. FIG. 3 shows an example of mounting the cross rail fixing member of the present invention as described above, and FIGS. 10 to 13 show one solution to the problem described in the prior art.
As described above, when the L-shaped angle member 24 or the U-shaped angle member 27 is riveted to the lower surface or the side surface of the horizontal crosspiece (see FIGS. 14 and 15) and also to the side surface of the column, the inner surface of the column is formed. Although the head part 26 of the rivet cannot be inserted because the head part 26 of the rivet protrudes, as shown in FIG. 10, if a groove 28 for avoiding the head part 26 of the rivet is formed in the slide column 7 in the sliding direction, it can slide freely. The pillar 7 can be inserted into the pillar, and the problem can be solved by the same method as the construction method of the present invention. In addition, if the pillars are also provided with a groove-shaped pattern, they can be formed into a shape that looks good in terms of design.

Further, as shown in FIG. 11, the cross-sectional shape of the slide strut 7 is formed in a concave shape at a portion where the strut and the rivet 25 are fixed, and a groove for avoiding the head 26 of the rivet is formed. Good. In this case, the design becomes even better. However, if an L-shaped angle member or a U-shaped angle member is welded or adhered to the column as a temporary fixing, the difference in diameter between the column and the slide column is a concern, and it is sufficiently practical. Therefore, the formation of the groove is unnecessary.

Next, FIG. 3 described above is an example in which the horizontal rail fixing member 1 of the present invention is provided at the lowermost end of the column 8. According to this, the horizontal rail fixing member 1 serves as one accent. , Despite the different diameters of the strut 8 and the slide strut 7,
The step between the strut 7 and the slide strut 8 is apparently not noticeable. That is, the fixing member of the present invention and the handrail using the fixing member thus improve the aesthetic feeling.

[0028]

【The invention's effect】

(1) According to the cross rail fixing member of the present invention, the cross rail can be fixed to the handrail support pillar without forming a protruding portion such as a rivet head inside the handrail support pillar. (2) Further, according to the handrail using the horizontal rail fixing member,
The slide column can be moved into the handrail column at any position, and even if the handrail mounting surface has an inclination, the level can be adjusted by adjusting the slide column to move in and out of the handrail column, so that the head frame is horizontal and the handrail can be quickly moved. It can be installed easily and easily. (3) Further, since the cross rail fixing member of the present invention is attached to the lower end portion of the column, the column has a side effect and an additional effect that a strong aesthetic feeling is obtained.
