Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a structure of a grate constituting a handrail, a surface grate, and the like used for stairs, balconies, balconies, windows, and the like.

<Prior Art> For example, a handrail used for a balcony of a building is required to have various functions and performances such as design consistency with a building, a blindfold function, ventilation (ventilation), and daylighting, in addition to safety.

As the structural member and the type of the handrail, a lattice type and a panel type are generally used depending on the use site, conditions and the like. The panel type is constructed by straddling the panel material formed of plastic plate, glass plate, rough wire, etc. between the upper and lower horizontal rails of the handrail.Although the blindfold function is superior to the lattice type, depending on the ventilation function and the material. Since the daylighting function is inferior, its use site is relatively limited.

Therefore, there is a tendency that the grid format, which is relatively versatile in its usage range including economic efficiency, is more commonly used. In the lattice type, so-called standing members are hung and attached between upper and lower horizontal rails at appropriate intervals. As the shape configuration of the standing member, a columnar shape, a prismatic shape, a thin plate shape and the like are well known.

<Problems to be solved by the invention> The problem of the grid type is that the blinding function and strength occupy a large proportion. As a means for improving the blinding function and strength, it is conceivable to simply reduce the interval between the standing particles.

However, in the case where the stand has the above-mentioned cylindrical shape or prismatic shape, it is not economical in terms of material if the spacing between the stand is small, and the overall shape of the lattice tends to be relatively monotonous.

In addition, when the standing plate is a thin plate type, even if the spacing between the standing plates is made small, the function of blinding from the front is inferior, it is possible to hardly expect improvement in strength, and in addition, vibration noise may be generated by wind. Except for economy, it is inferior to the above two and becomes a problem.

The present invention is intended to solve the above-mentioned problem of the grid type.

An object of the present invention is to obtain a lattice having the above-mentioned blindfold function, high degree of excellence, and excellent assemblability.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention provides a plurality of standing beams between a pair of upper and lower horizontal bars at appropriate intervals, and the standing members are attached to the upper and lower horizontal bars. In the attached grid, the standing member is formed in a T-shaped cross section composed of a horizontal plate and a vertical plate projecting from one side of the horizontal plate in a direction orthogonal to each other. Has a lattice structure in which the end faces of the upper and lower horizontal rails are brought into contact with and attached to the upper and lower opposite faces.

Further, the vertical plate has a lattice structure in which end pieces integrally extending forward from the front end surface thereof and provided in the vertical direction from upper and lower end surfaces are respectively provided.

<Operation> In the lattice having the above structure, it is possible to secure a sufficient size to be shielded by the horizontal plate when viewed from the front, and to secure a sufficient size to be shielded by the horizontal plate and the vertical plate when viewed from an oblique direction. it can. Furthermore, since the upper and lower end faces of the horizontal plate and the vertical plate of the standing plate are in contact with the upper and lower side faces of the upper and lower horizontal rails, the horizontal plate prevents lateral deformation due to the upper and lower horizontal rails, and the upper and lower horizontal rails are prevented. The vertical plate prevents vertical deformation due to.

Further, the end pieces can be positioned with respect to the upper and lower horizontal rails when the standing piece is engaged.

<Embodiment> A preferred embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment in which the lattice according to the present invention is used for a balcony. FIG. 1 is a perspective view showing the shape and structure of the standing piece, FIG. 2 is a front view of the balcony, and FIG. 3 is FIG. X
-X line sectional main part configuration diagram, FIG. 4 is a YY line sectional main part configuration diagram of FIG.

In FIG. 2, the balcony B includes a lattice 1 on which a large number of standing pieces, which will be described later, are arranged, and a plurality of support columns 2 for supporting the lattice 1.
The main element is composed of a headstock 3 laid over the upper ends of the columns 2 and a floor member 4 protruding from a building (not shown). A so-called handrail is formed by assembling the above-mentioned lattice 1, support columns 2 and headstock 3.

As shown in FIGS. 3 and 4, the lattice 1 includes hollow rectangular upper and lower horizontal rails 10 and 11, which are vertically arranged at appropriate intervals, and between the upper and lower horizontal rails 10 and 11. It is composed of a plurality of standing particles 12 which are hung and laid across.

As shown in FIG. 1, the stand 12 has, for example, a thickness of 1
~ 2 mm flat plate-shaped horizontal plate 12a and this horizontal plate
It has a vertical plate 12b protruding from the center of one surface of 12a in a direction orthogonal to the horizontal plate 12a, and is formed in a T-shaped cross section. The vertical plate 12b is also a thin flat plate like the horizontal plate 12a, and both can be integrally formed by, for example, an aluminum drawing material. 12c and 12d
Is an engaging piece obtained by cutting and bending a part of the upper and lower ends of the vertical plate 12b.Usually, with the means to be described later, the engaging pieces 12c, 12d are bent as shown in the figure by bending the upper lateral bar 10 and the lower horizontal bar. Attach to pier 11.

The upper horizontal rails 10 and the lower horizontal rails 11 are hollow prisms having openings in one surface in the longitudinal direction, and these opening surfaces face downward when assembled as the grid 1 to form the upper horizontal rail plate 10a and the lower horizontal rail plate. 11a is fitted and closed.

The upper horizontal rail 10, the lower horizontal rail 11, and the standing member 12 are assembled in the following manner.

First, in the upper horizontal rail 10, on the upper horizontal rail plate 10a, and in the lower horizontal rail 11 on the upper surface side thereof, the engaging pieces 12c, 12 of the standing ribs 12 are placed at positions corresponding to the intervals of the standing ribs 12, respectively.
Drill the insertion slit (not shown) of d. Then, the engaging piece of the standing child 12 is inserted into each of these insertion slits.
12c and 12d are inserted, the upper horizontal rail plate 10a side is attached from the plate upper surface, and the lower horizontal rail 11 is attached from the opening surface side.
Bending of 12c and 12d is performed as shown in FIG. At this time, each standing member 12 has a lower surface of the upper horizontal rail plate 10a and an upper surface of the lower horizontal rail 11 in which the upper end surface 12e and the lower end surface 12f of the horizontal plate 12a and the vertical plate 12b correspond to the upper and lower surfaces of the upper and lower horizontal rails. Is abutted against and fastened. And in sequence, the required number of 12
About the above work.

In this assembling of the stand 12, as shown in FIG. 3, the lateral plates 12a of the stand 12 are arranged in a line in the same plane, so-called flush.

After the assembly of the standing beam 12 and the upper horizontal rail plate 10a and the lower horizontal rail 11 is completed, the upper horizontal rail 10 and the lower horizontal rail plate 11a are
Are fitted to the upper horizontal rail plate 10a and the lower horizontal rail 11, respectively.
This completes the assembly of the grid 1 with the required dimensions.

The lattice 1 is supported by the columns 2, but in the case of the illustrated example, the lattices 1 are not mounted flush with each other between the columns 2, but by the upper horizontal beam receiving arm 5 and the lower horizontal beam receiving arm 6 from the surface of the column 2. It sticks out and is attached.

In this case, the lattice 1 is mounted in the direction in which the lateral plate 12a of the standing member 12 faces the indoor side.

Both arms 5 and 6 have the same shape, and the mounting pieces 5a and 6a to the column 2 and the receiving pieces 5b and 6b of the upper horizontal rail 10 and the lower horizontal rail 11, respectively.
Is formed. The receiving pieces 5b and 6b fix the upper horizontal rail 10 and the lower horizontal rail 11, respectively, and actually the upper horizontal rail plate 10a and the lower horizontal rail plate 11a, with screws 7a and 7b, respectively. Also, the mounting pieces 5a, 6b
Are fixed to the side surfaces of the column 2 with rivets 8a and 8b, respectively. Reference numeral 9 is a reinforcing material, which is used for fastening portions of the arms 5 and 6 with the rivets 8a and 8b when the support column 2 has a relatively low strength such as an aluminum material. 4a is prop 2
Is a foundation for pillars formed on the floor member 4 of the balcony B to stand upright.

According to balcony B as above, each standing child 12
By appropriately setting the arrangement interval P (see FIG. 3), it is possible to obtain a blinding effect which has not been found in the past.

For example, when the width W ₁ of the horizontal plate 12a of the standing member 12 is 30 mm and the protruding width W ₂ of the vertical plate 12b is about 60 mm, the arrangement interval P is 8
A practical blindfold effect can be obtained at about 0 to 90 mm. In this case, the other functions of the grating 1, that is, the ventilation, the daylighting property, the strength, and the like, are practically sufficient. Also, in terms of economy in terms of material, since the standing member 12 is a thin plate material, it is possible to reduce the weight and manufacture at low cost. Further, the lattice 1 can be made to have a characteristic appearance in which a large number of vertical plates 12b are projected as an appearance from the outside. In this case, as shown in FIG. 4, end plates 12b ₁ and 12b ₂ projecting vertically on the front end face 12g side of the vertical plate 12b are extended to the side surfaces of the upper horizontal rail 10 and the lower horizontal rail 11. If provided, the end pieces 12b ₁ and 12b can be used as a positioning jig when attaching the standing member 12 to the upper and lower horizontal rails 10 and 11, and can be brought into contact with the side surfaces of the upper horizontal rail 10 and the lower horizontal rail 11. The strength of the grid 1 can be improved. In addition, the upper horizontal rail 10 and the lower horizontal rail 11 can be made less visible and the vertical line of the standing beam 12 can be emphasized.

In the above embodiment, the case where the balcony 1 is used as a handrail has been described, but the lattice 1 of the present invention can also be used for other parts as a construction material. For example, on a surface lattice such as a window, or on a handrail such as an apartment house,
It is also used as a fence.

<Effect of Device> As described in detail above, according to the structure of the lattice of the present invention, the horizontal plate and the vertical plate provide a sufficient shielding area even when viewed from the front and the oblique direction. You can secure and improve the blindfold function.

This blindfold function can be a function of hiding the pillar as well, if the lattice is projected from the pillar to the outside through the arm, and the design effect can be enhanced.

In addition, the upper and lower end faces of the horizontal plate and the vertical plate contact the vertically opposed faces of the upper and lower horizontal rails to prevent lateral and vertical deformation of the lattice, thereby improving the strength of the lattice. You can

Further, by providing the vertical plate with the end pieces, the vertical plate can be positioned with respect to the upper and lower horizontal rails when the standing plate is engaged, and the assembling property of the lattice can be improved.
