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 handrails, enclosure walls, drainage walls, etc., which are exposed to rain, and the wall end surface similar to roof surfaces, such as overhanging passages to the outside. In the general building structure shown, as indicated by hatching, there are handrails A on the roof, handrails B on the rooftop parking lot, handrails C on the balcony,
There are extremely many end surfaces 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 reduce the slope of the top surface of the cover plate when constructing rain cover work at many locations where the width of the open end surface is variable. To provide a rain cover device for an open end face of a building, which can be easily and effortlessly assembled in a predetermined public distribution.

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 that are externally fitted and a required number of joint plates 5 that connect the cover plates 4 to each other.

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 stands 6A and 6B,
It is formed by a pair of support plates 7A and 7B.

Therefore, the table 6A consisting of a block with an L-shaped cross section,
6B is two rows of long mounting holes 6 drilled in the bottom plate.
A is inserted into the anchor bolt 8 of the handrail wall 1 and tightened with a nut, and the vertical plate part 6b along the longitudinal direction of the end surface 1a has a through groove 6c that runs through it horizontally.
is cut off, and a tooth profile row for preventing removal is formed on the inner wall surface of the groove 6c.

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 an inverted dish bottom shape with both ends downward. It is divided into two halves 9 and 10, an inner half plate and an outer half plate, which overlap each other at an intermediate flat location.

Thus, the inner half plate 9 has a cross-sectional shape that is fitted into the lower surface of the inner end of the flat portion so as to be rotatable in the transverse width direction of the end surface 1a in close contact with the support head 7a. A circular engaging groove 9a passes through the flat part, and a plurality of rows (four rows in the figure) of insertion recesses 9b having a reverse trapezoidal cross section are arranged at regular pitches in parallel with the engaging groove 9a. Perforated at intervals.

On the other hand, the outer half plate 10 has an engagement groove 10a on its bottom surface that has the same shape as the engagement groove 9a of the split plate 9.
, but on the upper surface of the flat part,
A plurality of rows (usually two rows) of protrusions 10b are formed to be selectively inserted into the grooves 9b.

(c) Cover plate 4 (see Figures 2, 3, and 6 to 8) This cover plate 4 has two parts, an inner plate 11 and an outer plate 12.
The inner plate 11 is divided into two parts, and the overall cross section has an inverted hat shape. A plurality of rows (usually two rows) of convex ridges 12 are formed on the upper surface of the distal end of the outer plate 12 with a plurality of rows (four rows in the illustration) of grooves 11a having a circular cross section.
By selectively extrapolating to a, it is joined into a single plate.

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 Using the elasticity of the cover plate 4, the hem of the cover plate 4 is expanded, 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 is used to connect the cover plates 4 to each other.
is made of a plate material whose cross-sectional shape is an inverted dish bottom shape inscribed in the cover plate 4 and has an appropriate width,
It is divided into a pair of half plates 14 and 15 that overlap each other at a flat intermediate portion.

Both split plates 14 and 15 are made of equal flat members, and specifically, after cutting the same plate material according to its respective extension length, key points in the middle are cut into L. Therefore, the horizontally 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. And on the bottom surface of the stepped portion 14b,
The female cutout 14c facing the male cutout is recessed, and the split plate 15 also has the same shape.

In the illustrated state in which both the split plates 14 and 15 overlap, the raised ridges of the outer split plate 15 are inserted into the cut strips 14c of the inner split plate 14, and the raised ridges 14a of the inner split plate 14 and the cut strips of the outer split plate 15 are playing together.

In addition, in the illustrated state in which both split plates 14 and 15 are overlapped to a position corresponding to the width of cover plate 4, both split plates 1
4 and 15 are fixed at the center of the joint plate 5 with a screw 16.

In order to connect the cover plate 4 using the joint plate 5, first attach a pair of cushion belts for buffering and water stoppage between the step portions 14a on both sides of the screws 16 on the upper surface of the inner split plate 14. After gluing 17, the joint plate 5
One half of the cover plate 4 is inserted into the inside of one cover plate 4, and then the other adjacent cover plate 4 is inserted into the other half of the joint plate 5. In that state, the cover plate 4 is , are connected through friction with the joint plate 5, and the screw 1
The space on the upper surface of the inner split plate 14 to which the cover plate 6 is attached becomes a water conduit, and water leaking from the gap between the cover plates 4 at the connection part 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.

When installing this rain cover device, the inclination angle between the exposed end face 1a and the mounting bracket 3 can be easily adjusted by changing the insertion height of the support plates 7A, 7B into the bases 6A, 6B, and during this adjustment, no undue stress is generated in any part due to the smooth engagement between the heads 7a of the support plates 7A, 7B and the engaging grooves 9a, 10a of the mounting bracket 3.

In addition, the above-mentioned shaped stands 6A, 6B and support plate 7A,
In addition to 7B, multiple stands and base plates with different heights are available, so by selecting the type of stand and base plate to be used, it can be adapted to construction work in various locations where the open end surface has a wide range of public distribution. This allows for easy on-site work.

As described above, according to the raincovering device for an open end face of a building according to the present invention, the mounting bracket is supported by a pair of height-variable base plates, and the engagement portion between the mounting bracket and the base plate is Because it is configured to be tiltable, it can also be used in waterproofing work on various types of open-air end surfaces with miscellaneous specifications.
This has the effect of simplifying on-site work.
