Description

[Detailed Description of the Invention] This invention relates to a rain covering device for an open end face of a building to prevent rainwater from seeping into the inside of a building wall material such as concrete from the open end face of a wall.

Here, the term "open-air end surface" refers to the upper end surface of a handrail, enclosure wall, drainage wall, etc. that is exposed to the rain, and the wall end surface similar to a roof surface such as a passage leading to the outside.For example, as shown in Figure 1, In the structure of a general building, as indicated by hatching, handrail A on the roof, handrail B on the rooftop parking lot, handrail C on the balcony,
There are many edges where rainwater may seep, such as the tower enclosure D, the flower podium enclosure E, the top surface F of the concrete pillar, and various other water cut walls G.

However, if the waterproofing of these end faces is inadequate, it is clear that the wall materials will deteriorate due to rainwater infiltration, and the weather resistance of the building will be significantly reduced.

By the way, as a concrete waterproofing measure for the edge of an open roof, in the past roofers used to install tiles or copper plates on the edge, but such measures require specialized skills and a lot of work. Due to the time-consuming process, it is difficult to adapt it to industrial production.Therefore, recent efforts have been made to cover the end face completely in the longitudinal direction with a prefabricated metal cover plate to some extent. It is being

However, the problem with industrial production of raincovering devices is that the locations and structural dimensions of the open end surfaces of buildings vary widely, and this makes it difficult to standardize and unify waterproofing construction. It is quite difficult, and furthermore, it is difficult to check the quality of the construction work from the outside, so it is difficult to manage the construction.In light of this current situation, it is difficult to control the construction of the end rain covering device. There is a strong demand for construction materials to be as versatile as possible, thereby simplifying the rework and adjustment work that must be carried out by craftsmen on site.

Although the present invention was developed in view of the current situation, the purpose of the present invention is to improve the installation of cover plates and their To provide a rain covering device for an open end face of a building, which eliminates the need to adjust the length of a mounting fitting forming a skeleton on-site each time.

Hereinafter, the present invention will be explained based on an illustrated embodiment.

FIG. 2 shows a plan view of the rain cover device of the embodiment applied to the handrail portion of FIG. 1, and as shown in FIGS. A support bracket 2 that is fixed to and stands up, a mounting bracket 3 whose lower surface is attached to the support bracket 2 and is suspended horizontally in the width line direction of the end surface 1a, and a plurality of mounting brackets 3 (three locations in the illustration). It is formed by a large number of fixed-length cover plates 4 which are externally fitted on the cover plates 4, and a required number of joint plates 5 connected between each cover plate 4.

Hereinafter, the formation mode of each of the above members will be described.

(a) Support metal fitting 2 (see Figures 3 and 4) This support metal fitting 2 is erected on both sides of the outside of the end surface 1a, that is, the right side in the drawing, and the inside of the end surface 1a, that is, the left side of the drawing. It consists of a pair of assembly parts of similar shapes, that is, a pair of bases 6A,
6B, and a pair of support plates 7A and 7B.

Therefore, the stand 6 is made of a block with an L-shaped cross section.
A and 6B are longitudinal plates that are tightened with nuts by inserting two rows of long mounting holes 6a drilled in the bottom plate into the anchor bolts 8 of the handrail wall 1, and that extend along the longitudinal direction of the end surface 1a. In the portion 6b, a horizontally extending through groove 6c is cut out, and the same groove 6c is cut out.
A row of teeth is formed on the inner wall surface to prevent it from coming off.

On the other hand, the upper ends of the support plates 7A and 7B, which are inserted into the through grooves 6c by meshing tooth rows, form a cylindrical head 7a.

(b) Mounting bracket 3 (see Figures 2 to 5) This mounting bracket 3 is a thick long plate member with the same width as the support bracket 2, and has both ends downward in the shape of an inverted dish bottom. It is divided into two halves 9 and 10, an inner half plate and an outer half plate, which overlap each other at a flat part in the middle.

Therefore, the inner half plate 9 has an engagement groove 9a that loosely fits into the above-mentioned support fitting head 7a passing through the lower surface of the inner end of the flat part, and the flat part has an engagement groove 9a that loosely fits into the support metal head 7a. Multiple rows (four rows in the illustration) parallel to the matching groove 9a.
Fitting grooves 9b having an inverted trapezoidal cross-section, that is, a dovetail groove shape, are bored at regular pitch intervals.

On the other hand, in the outer half plate 10, an engagement groove 10a passes horizontally in a manner symmetrical to the split plate 9, and on the upper surface of the flat part, a groove 10a is selectively inserted into the above-mentioned engagement groove 9b. A plurality of rows (usually two rows) of dovetail-shaped fitting protrusions 10b are formed.

(c) Cover plate (see Figures 2, 3, and 6 to 8) This cover plate 4 is divided into two parts, an inner plate 11 and an outer plate 12, and the overall shape is has an inverted hat-shaped cross section, so both plates 11,
12 is a plurality of rows (in the illustration, 4
The concave grooves 11a having a circular cross section (row) are selectively extrapolated to the plurality of rows (usually two rows) of convex ridges 12a protrudingly formed on the upper surface of the tip of the outer plate 12, thereby creating a single plate shape. is joined to. Above groove 1
1a and the convex ridge 12a are formed into a dovetail groove shape and a dovetail pattern shape that fit into each other as shown in the figure,
Moreover, the intervals between the grooves 11a and the protrusions 12a are the same as the intervals between the fitting grooves 9b and the fitting protrusions 10b.

In addition, at the lower ends of the hanging side plates of each of the plates 11 and 12, flanges 11b and 12b, which correspond to the inner and outer hem edges of the mounting bracket 3, protrude inward.

Therefore, in order to attach this cover plate 4 to the mounting bracket 3, first, the cushion belt 13 is adhered to the top surface of the mounting bracket 3, and then the cover plate 4 is inserted from the side of the bracket 3, or The elasticity of the cover plate 4 is used to widen the hem of the cover plate 4, and the plate 4 is pushed in from above the mounting fitting 3 to hook the collars 11b and 12b.

(d) Joint plate 5 (see Figures 2, 7, and 8) This joint plate 5, which is used to connect the cover plates 4 to each other, has an inverted dish bottom cross-sectional shape that is inscribed in the cover plate 4. 1 made of plates with appropriate width and overlapping each other at the flat part in the middle.
It is divided into a pair of half plates 14 and 15.

Both split plates 14 and 15 are made from equal flat members, and specifically, after cutting the same plate material according to its respective extension length, key points in the middle are cut. It is formed by bending into an L shape, and therefore, the horizontal flat portions of each of the split plates 14 and 15 have exactly the same shape.

For example, in the cross-sectional shape of the horizontal portion of the inner split plate 14, a large number of bulging step portions 14a are formed on the upper surface of the plate, and an inverted trapezoid-shaped male protuberance 14b protrudes from the upper surface of the step portion 14a. Further, a female cutout 14c opposite to the male cutout is recessed in the bottom surface of the stepped portion 14b, and the shape of the split plate 15 is also the same shape.

In the illustrated state in which the two split plates 14 and 15 overlap, the raised ridges of the outer split plate 15 are the same as those of the inner split plate 15.
It is inserted into the cut strip 14c of the inner split plate 1.
The raised peak 14a of No. 4 and the cut line of the outer split plate 15 are as follows.
playing together.

In addition, in the illustrated state in which both the split plates 14 and 15 are overlapped to a position corresponding to the width of the cover plate 4, the space between the split plates 14 and 15 is fixed by a screw 16 at the center of the joint plate 5.

In order to connect the cover plate 4 using this joint plate 5, first install a buffer and water stopper between each step 14a on both sides of the screw 16 on the upper surface of the inner split plate 14.
After adhering the pair of cushion belts 17, one half of the joint plate 5 is inserted into one cover plate 4, and then the other cover plate 4 adjacent to the other half of the joint plate 5 is removed. In that state, the cover plate 4 is connected through friction with the joint plate 5, and the upper surface space of the inner split plate 14 to which the screws 16 are attached is connected to the water conduit. In this way, water leaking from the gap between the cover plates 4 of the connecting portion is drained to the outside of the handrail wall 1.

In the handrail wall 1 equipped with the rain cover device of the embodiment configured as described above, after rainwater falling on the handrail hits the cover plate 4, it is directed outward of the handrail wall 1 due to the slope of the upper surface of the cover plate 4. Since the water is drained away, rainwater is prevented from seeping into the inside of the handrail wall 1.

Therefore, when carrying out the construction of this rain cover device, by selecting the fitting groove 9b of the inner half plate 9 into which the fitting protrusion 10b of the outer half plate 10 is inserted, the mounting bracket can be installed. It is possible to change the length of 3, and the pitch interval that can be selected at that time is sufficiently smaller than the gap size width between the handrail wall 1 and the hem edge of the rain cover 4 that is permissible for waterproofing. Since this setting is made, it is possible to handle construction work at various locations where the width of the open end surface 1a is different, without having to adjust the length of the mounting bracket 3 one by one on site.

In addition to the illustrated half plates 9 and 10, the inner half plate has 5 rows of fitting grooves 9b.
~ 6 rows, and the engaging groove 9a and the fitting groove 9
Various shapes of split plates are prepared, such as those in which the distance between the engagement groove and the fitting protrusion 10b is extended in several steps, and for the outer half board, the distance between the engagement groove and the fitting protrusion 10b is extended in several steps. Since the stretched split boards are prepared, by selecting the type of split boards to be used, from narrow end faces such as cut walls,
It can be applied to a wide end surface such as a passageway roof, and can be applied to a wide range of construction work, so it is extremely easy to work on site.

As described above, according to the rain covering device for an open roof end face of a building according to the present invention, both the cover plate 4 that covers the open roof end face 1a and the mounting bracket 3 that attaches this cover plate 4 to the open roof end face 1a can be attached to the open roof end face. 1a is divided along the longitudinal cover plate 1a so as to be expandable and contractible according to the width of the exposed end surface 1a, and the dividing lines of both sides are overlapped vertically, and dovetails are fitted to each other on the overlapping surfaces of both sides. A plurality of rows of fitting grooves 9b and fitting protrusions 10b and similar grooves 11a and convex ridges 12a are molded to match, and forming gaps between the plurality of rows of fitting grooves 9b and fitting protrusions 10b on the mounting bracket 3 side are formed. Since the grooves 11a and the protrusions 12a on the cover plate 4 side are formed at the same intervals, the widths of both the cover plate 4 and its mounting bracket 3 can be set at an accurate pitch according to the width of the exposed end surface 1a. It has the effect of being able to be adjusted in unison.

Further, as described above, the fitting groove 9b and the fitting protrusion 10b, which are fitted into each other, and the concave line 11a and the protrusion 1
2a has a dovetail fitting structure with a dovetail groove shape and a dovetail pattern shape, both of which make the inner part wider than the entrance part, so it can be attached to the cover plate 4 which is divided into front and back parts along the longitudinal cover plate of the open end surface 1a. The metal fitting 3 has a split joint surface that does not shift vertically or front to back even without using auxiliary joints such as rivets or screws, and that rainwater etc. do not infiltrate from the joint surface. This also has the effect of improving the workability of installing the cover plate 4 and the mounting bracket 3.
