Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a waterproof structure on the roof of a building, and particularly relates to a waterproof structure with an external rooftop insulation sheet that has a structure that integrates a waterproof sheet and external rooftop insulation. .

[Prior Art] Conventionally, waterproofing of the roof of a building has been carried out by applying an adhesive to the entire surface of the building's frame, and then laying and adhering a waterproof sheet thereon. Furthermore, when external insulation is required on the roof of a building, "rooftop external insulation structure" (JP-A-57-
197348). In other words, two-pronged work was being carried out: waterproofing work on the roof of the building and insulation work outside the roof.

[Problems to be Solved by the Invention] However, the so-called two-tree structure, which is a structure using a conventional waterproof sheet and a structure using external roof insulation, has the following problems.

(1) Since the waterproof sheet is completely adhered to the entire roof of the building using adhesive, adhesive and adhesive application work is required.

(2) There is a restriction that adhesive application work cannot be done in rainy weather.

(3) The N upper and outer insulation structure is assembled on top of a waterproof sheet, and in order to prevent it from being blown away by strong winds, the loop panels are made of concrete and require considerable weight. For this reason, (1) costs increase;
(2) Since there may be cases where the strength is insufficient for the capacity of the building, the buildings that can be adopted are limited.

There were problems such as.

[Purpose] The purpose of the present invention is to solve the problems of the prior art and to integrate a waterproof sheet and an external roof insulation structure, which can protect the roof of a building at low cost and reliably. The purpose of the present invention is to provide a sheet waterproof structure with external roof insulation.

[Means for achieving the object] The present invention provides fixing members arranged at regular intervals on the top surface of a product frame on the roof of a building, fixing the fixing members with anchors, and covering the top surface of the fixing members with a waterproof sheet. After temporarily fixing the waterproof sheet to the fixing member using a male-threaded holding member, screw the joiner into the male-threaded holding member and tighten and fix the waterproof sheet. A space is provided above the insulation material board, and the loop panels are arranged in the vertical and horizontal directions, and a space is provided above the insulation material board. - and by fastening with a cap,
This aims to achieve the above objectives.

[Example] The present invention will be specifically described below with reference to the drawings.

FIG. 1 is a perspective view showing one embodiment of the present invention, FIG. 2 is a cross-sectional view of essential parts showing the support structure of the present invention, FIG. 3 is a detailed perspective view of the support member, and FIG. FIG. 4 is a detailed sectional view of the support member.

Details of the support member will be explained with reference to FIGS. 13 and 4. 6 shows an anchor 0 Figure shows a screw-nail shaped anchor, but there are various types of anchors for concrete, and any of them can be used. Reference numeral 5 designates a fixing member. The fixing member 5 has an upper opening 51 formed in the center of a fixing seat 52, and an anchor attachment hole 53 provided in the center. Reference numeral 4 indicates a male-threaded holding member. The male-threaded holding member 4 has a male threaded portion 41 formed on its outer periphery, and is provided with several notches 42 to facilitate engagement with the upper opening portion 51 of the fixing member 5. There is. 3 indicates a joiner.

The joiner 3 includes a male screw part 31, a cylindrical part 32, and a leg seat part 3.
3, and on the inside of the leg seat part 33 there is a female threaded part 34 that is screwed into the male threaded part 41 of the male threaded holding member 4.
is provided. Reference numeral 2 indicates an air layer holding 7 flange. Air layer holding flange 2 consists of a flange portion 21 and a cylindrical portion 22, and the inner cylindrical portion 23 has a size that can be fitted onto the cylindrical portion 32 of the joiner 3. 1 indicates a cap, cap 1
consists of a head portion 11, a body portion 12, and a female threaded portion 13, and the female threaded portion 13 is provided so as to be able to be screwed into the male threaded portion 31 of the joiner 3.

FIG. 2 is a sectional view of a main part showing a support structure of the present invention using the support member shown in FIG. 3. FIG. Building frame on the roof of a building
A fixing member 5 is fixed to the top surface of O with an anchor 6, the top surface of the fixing member 5 is covered with a waterproof sheet 9, and a male threaded holding member 4
After temporarily fixing the waterproof sheet 9 over the fixing member 5,
After screwing the inner jacket 3 into the male-threaded holding member 4 and tightening and fixing the waterproof sheet 9, the insulation boards 8 are placed on the leg seats 33 of the joiner 3 and the insulation boards 8 are arranged vertically and horizontally. After laying the air layer, insert the air layer holding flange 2 into the cylindrical part 32 of the joiner 3, and then insert the air layer holding flange 2 into the cylindrical part 32 of the joiner
1, lay the loop panels 7 in rows and columns, and attach the corner corners of the adjacent loop panels 7 with the cap 1 to the joiner 3.
It is screwed into the male threaded portion 31 of the connector and fastened. The thing completed as described above is the perspective view shown in FIG. 1.

[Effects] As is clear from the above explanation, according to the present invention, (1) the waterproof sheet does not use adhesive, so there is no cost for adhesive, and there is no need for man-hours for applying adhesive; It is not affected by the weather when applying the agent.

(2) The fixed member is fixed to the building frame with anchors.

Moreover, the fixing member, joiner, and cap are connected by a threaded part, and the loop panel is held down by the cap, which is effective in preventing the loop panel from scattering due to strong winds and reducing the weight of the loop panel. ,
This will solve the problem of insufficient building strength.

(3) By reducing the weight of the loop panel, the cost of the loop panel becomes cheaper, and the light weight also makes the construction work easier.

(4) In the case of renovation work, there is no need for special ground preparation, so it can be done at low cost.

(5) The waterproof sheet can be fixed to the base without penetrating it, so there is no need to worry about rain getting wet.

To obtain a sheet waterproof structure with external roof insulation that is safe, reliable, and can be provided at low cost.
