Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a filling layer of a waterproof layer.

Conventionally, cement or concrete mortar has been applied directly to the upper surface of a waterproof layer applied to a concrete subsurface such as the roof of a concrete building, or through a heat insulating layer applied to the upper surface. Generally, a protective oil with a thickness of 5 to 1 ocrn is formed to allow people to walk around and use rooftops (r-measured).

However, the protective layer expands and expands during the season, and there is a risk that the waterproof layer on the roof will be pressed down and damaged, especially when it is on the rooftop.

There is. Cement or concrete mortar is also susceptible to cracking due to expansion and contraction due to temperature differences, which may damage the waterproof layer attached thereto. ,mosquito\
In order to eliminate this problem, joints are usually set at 3 to 4 m intervals, and elastic joint material such as foamed plastic is used in the joints. Power!
iN. A method of forming a protective barrier layer of a waterproof layer is being carried out which prevents the above-mentioned disadvantages due to this buffering effect. To describe this conventional forming method in detail, Fig. 1, Fig. 2 and Fig. 3: VC
As shown in Figure '1-, the upper surface of the waterproof layer such as asphalt roofing applied to the upper surface of the concrete base a is in contact with 1r in the case shown in the second figure, and on top of it in the case shown in the third figure.
When forming the reef-preserving layer d through the VC polymeric adhesive (7 minutes), apply a longitudinal elastic joint material of Ijt Ya Nao on each upper surface before forming the layer d. The upper surface of the thermal material C and the base of the joint material e
S v A stiff joint A3' e is fixed in an upright state through mortar fr for fixing the joint material applied in the length direction f1'i. 1) Fixing of base material e] A large number of joint materials e are arranged in a horizontal and vertical grid pattern as shown in Figure 1, and the vertical and horizontal grid-like joint materials are A large number of rectangular cement joints are carved into eve... 1 concrete mortar-filling recessed space, and each recessed space is filled with four frames of cement or concrete mortar. It is injected and filled in a trench at a height of e, and dried and solidified to form a large number of protective oils through the joint holes, and as shown in Figure 2, asphalt etc. The waterproof coating material was applied and the construction was completed.

In Fig. 3, instead of using the seal as a waterproof material, a professional waterproof joint cap g' with a U-shaped pr surface is fitted on the two sides of the long joint material e as a sealing material. Something,
In this case, it is necessary to install a pair of supports from both sides 11111 to support this state (I-maintain), and install them with mortar f for fixing hf.The length of each joint material e It is necessary to carry out the training at a predetermined interval in the direction.

In this way, in order to form the protective valve layer of the above-mentioned waterproof layer, it is extremely difficult to form a recessed space for mortar injection with a joint material before filling the mortar, and it takes a very long time for fraying. +- Not only is it cheap and inefficient, but if the waterproofing layer is to be repaired or destroyed, the mortar retaining layer must be destroyed and removed, and that work is troublesome and inefficient. , the removal trace Kli' is filled with concrete or cement mortar 112, and the entire retaining layer cannot be reused and is uneconomical. Destruction and removal of layers is extremely difficult, especially when working on the roof of a subdivision area.

The present invention solves the disadvantages of the conventional method.
, you can easily and quickly form the protective valve layer of the waterproof layer, and
When repairing and replacing the waterproof layer, the protective layer can be quickly removed without destroying it (tI-IrL).

Also, it proposes a method for forming a pus-retaining layer of a waterproof layer that can be used.
- A large number of thermal adhesives are attached to the upper surface of the waterproof layer applied to the subsurface surface or through the insulation layer applied to the upper surface (7
A flexible joint filler is loaded into the joints, and cement or concrete mortar is filled into each open sludge and dried and solidified to form each protective valve layer.

In addition, in the conventional method, gaps are likely to be formed between the joint material e1, the waterproof coating material g, the waterproof joint cap g', and the protective valve layer d, and water infiltrates through these gaps, causing damage to the concrete mortar. Accompanied by strong alkalinity, this alkaline water causes inconveniences such as deterioration of the waterproof layer (B1 insulation material such as asphalt on the underside of the work) and damage to its durability.

In addition to achieving the above objectives, the present invention further prevents alkaline water from reaching the insulation material and waterproof layer surface and deteriorating them, and maintains the good properties of the insulation material and waterproof layer over a long period of time. A complete method for forming a protective barrier layer for a waterproof layer to obtain a waterproof layer is provided, in which a waterproof layer is formed on the concrete subsurface, and a heat insulating layer is applied to or above the upper surface of the waterproof layer. A large number of open box body joints are lined up through the joints, and a synthetic resin foam joint material is loaded into the joints, and a cross-section is made across the MiiA border on the top surface of the joint material and on the side walls of the box body on both sides. The following embodiments of the present invention are characterized in that after the waterproof caps are fitted together, cement or concrete mortar is filled into each of the boxes, dried and assimilated to form all the retaining layers. 'f Let's explain the attached drawings below in Figure 4.

Figure 4 shows 1 of the open box body Ill used in the tree 9h light method.
All examples are shown, and the box body il+ consists of a bottom plate (1a) and four surrounding side plates (
It consists of a rectangular frame body with an open top surface consisting of 1b). In general, its size and shape are free, but as described later, it can be filled and molded;/1f? :.

Relatively small size that can be transported by a small number of workers with concrete or mortar cement protective valve layer interposed! (It is preferable to make it light and nimble, for example, by molding it to about 1 m in length and width x 1 m% in depth, that is, about 5 to 10 cm in height. Corrosion resistance Q kA of purchased yarn, synthetic resin yarn, foamed synthetic resin, stainless steel, etc.
The boxes are made from materials such as thread, bird-proofed wood, asbestos, glass, and inorganic materials such as cement, making them highly waterproof and durable. The box is manufactured by gluing and welding plate members.
Also, press working, mold molding, etc. are optional.

Of course, the joint material (5) is not limited to this foam, and any suitable fixed or irregularly shaped joint material such as elastic rubber, liquid rubber, or asphalt may be used as long as it serves as a cushioning material. For this work, the joints (4
), so that it is convenient to fill and use an irregularly shaped joint material between them.In addition, it is convenient to use conventionally used shaped plastic foam on both opposing walls (lbl()) of the adjacent box bodies 111111. Can be clamped and fixed with lbl,
The fixing work is much simpler than the conventional method.

Next, fill each /11 ~ body il+... with fresh concrete or cement mortar mixed in advance, and make it flat at the same level as the top of the 5111 wall (1b) of the box 1). In this state, the VC is left to dry and solidify to form a retaining layer +6 of the waterproof layer (3) inside each box (1). In addition, plastic foam joint material; 51

In this way, according to the present invention, on the upper surface of the waterproof layer, a large number of open boxes are lined up with a certain number of joints fully present, and an elastic joint layer is loaded in the ground, and concrete is placed inside each box. Or, since the cement mortar is allowed to dry and solidify in the presence of light, the protective layer of the waterproof layer can be quickly formed at each location.
Since the elastic joint material and the caps are fitted to both side walls of the box body to be fully clamped, there is no possibility of water intrusion into the joints on the bottom surface, and each box body It prevents the waterproof layer or the heat insulating layer applied on its upper surface from the harmful effects of alkaline water, and maintains good 14/+ water resistance and heat insulating properties for a long time. When repairing or replacing the layers, do you need to repair the joints around the outer periphery of the box? It is sufficient to simply cut it and transport and remove it together with the box without destroying the holding layer at all.
