Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a protective structure for the end of a waterproof layer on the roof of a building, and more specifically, for the end of a waterproof layer on an outer peripheral wall or an outside wall of a tower.

[Prior Art] When there is a rising part on the roof of a building, such as an outer peripheral wall or a tower, it is necessary to extend the end of the rooftop waterproof layer to the rising part to ensure the full waterproof effect.

On the other hand, the waterproof layer depends on the usage situation of the rooftop.
It is necessary to form a protective layer on top of it to maintain its waterproof function. In other words, depending on whether the rooftop is used for normal walking and other activities like a normal floor surface, or whether it is only for light walking, etc., the waterproof layer on the rooftop floor may be The protective layer must be formed on the surface.

The necessity of this protective layer is exactly the same in the waterproof layer at the rising parts of the outer peripheral wall, tower building, etc., and the protective structure shown in FIG. 4 is conventionally known as a protective structure for this part.

In the figure, 1 is a shielding plate usually called a Kasagi, which is connected to the support 2 and has an outer peripheral wall 6 on the frame side.
By shielding the top portion all around, a protective layer is formed for the waterproof layer end portion 3 on the outer peripheral wall.

The supports 2 are fixed to the top of the outer peripheral wall 6 at predetermined intervals with screws through the waterproof layer 3 to support the shielding plate 1.

Reference numeral 3 denotes a waterproof layer that extends from the floor surface to the top of the outer circumferential wall 6 through the inner surface thereof, and its ends are sealed by sealing members 3a. Bricks 4 serve as a protective layer for the waterproof layer 3 on the inner surface of the outer circumferential wall 6, and are laminated with mortar 4a. 5 is a protective layer formed on the waterproof layer 3 on the floor surface.

In this way, the prior art shown in FIG. 4 shields and protects the waterproof layer 3 at the top of the outer peripheral wall 6 by the shield plate 1, and by masonry of bricks 4 at the inner surface of the outer peripheral wall 6. .

[Problems to be Solved by the Invention] However, in the above-mentioned prior art, the protection of the waterproof layer in the rising portion is achieved by laying bricks on the surface of the waterproof layer using mortar. The following problems have arisen.

(b) Because it uses the so-called wet construction method, in which bricks are laid with mortar, the construction period is long and costs are high because the construction requires professionals.

(b) Since the protective layer is configured to directly interfere with the waterproof layer, it will cause peeling and other negative effects on the waterproof layer during the construction process and thereafter.

(c) If it becomes necessary to repair the waterproof layer, the protective layer made of bricks covered with mortar is not easy to remove, resulting in a long construction period and an associated high cost.

In order to eliminate the inconveniences caused by the so-called wet construction method: (A) Protect the inner surface of the outer peripheral wall by suspending a protection board from the cape to protect it from water.

(B) Protect the waterproof layer on the inner surface of the outer peripheral wall by hanging a protective plate on the support.

Techniques related to protective structures using so-called dry construction methods have been proposed in the past.

However, in the case of (A), these conventional techniques: (i) Due to the difference in thermal contraction rate between the shielding plate and the protection plate,
The protective plate has significantly changed over time.

(ii) Since screws are used to attach the protective plate, the screw heads are exposed outside the shielding plate, spoiling its appearance.

(iii) Since the shielding plate and the protective plate are flush with each other, rainwater, etc. can easily reach the protective plate and cause it to become dirty.

In the case of (B): (i) The support is fixed to the top of the outer peripheral wall as the frame, and the upper end of the protection plate is fixed to this support and the lower end to the floor, so the protection plate is It is easily affected by the behavior of the building frame, and this is noticeable in buildings where the outer wall and floor are not integrally formed.

(ii) Since the supports are usually arranged at intervals of approximately 1M, the fixed position of the protection plate is fixed, making it difficult to allocate the protection plate and select the shape and material.

(iii) To remove the protective plate when inspecting and repairing the waterproof layer, it is necessary to also remove the shielding plate that is fitted to the support, which is time-consuming.

[Means for Solving the Problems] The present invention provides a method for forming a protective layer of a waterproof layer on the outer peripheral wall of a building rooftop, a tower building, etc.
This is made up of a support that is fixed to the shielding plate and the building frame and engages and supports the shielding plate, a hanger that is removably suspended from the support and suspends the protective plate, and a lower end of the protective plate. This is an attempt to solve the above-mentioned conventional problems by constructing a protective plate holder that fits together.

[Function] The protective layer according to the present invention has a structure in which the upper end of the protective plate is removably supported inside the support via a hanger, and the lower end is loosely attached to the protective plate holder, so that the attached state of the protective plate can be changed. It has a flexible structure and has no adverse effect on the waterproof layer, is easy to remove, does not require skilled work, and can shorten the construction period.

[Example] An example according to the present invention will be described based on the drawings. Note that the same parts as in the conventional example are given the same reference numerals, and repeated explanation will be omitted.

In the figure, 1 is a long shielding plate formed by extrusion molding of aluminum material, and the length is
Several types of dimensions such as width can be prepared to meet expected demands.

2 is fixed to the top of the outer peripheral wall 6 as a frame,
A force plate serving as a support for supporting the Kasagi 1, formed by extrusion molding of aluminum material,
It has a front edge 2b and a rear edge 2c which are inclined outwardly and downwardly, respectively, and the shielding plate 1 is fitted and supported at the front edge and rear edge portions. In this embodiment, the width of this support 2 in the direction of arrow B in FIG. 2b is approximately
It is 50mm long. And this support body 2 is 1
They are arranged at predetermined intervals of m or 2 m and support shielding plates (kasagi).
