Description

  The present invention relates to an inspection method after construction when a waterproof sheet is laid through a mechanical fixture such as a disk in an insulating waterproofing method for a flat roof or a veranda floor of a building such as a house or a building.

  On the verandas and rooftops of buildings such as houses and buildings, waterproofing measures are taken to prevent the penetration of rainwater into the living space existing in the lower layer. As a typical waterproof structure, a waterproof sheet on the waterproof base An insulation method is known in which a waterproof base and a waterproof sheet are partially welded. In such an insulation method, when the waterproof sheet is not bonded to the waterproof base at a predetermined location, problems such as the waterproof sheet being peeled off from the waterproof base due to the blowing by the wind are likely to occur. Therefore, it is necessary to inspect whether or not the waterproof sheet is well bonded to the waterproof base at a predetermined location after the waterproof sheet is applied, and repair the defective bonding location after the inspection. As such an inspection method, for example, in Patent Document 1, a sucker is adsorbed to a waterproof sheet in the vicinity of an adhesion point, and a waterproof sheet that is not adhered to a waterproof substrate is pulled up by pulling the sucker vertically, and bonded to the waterproof substrate. An inspection method for confirming a boundary between a portion that is attached and a non-adhered portion is disclosed.

JP 2004-132167 A

  However, in the inspection method disclosed in Patent Document 1, it is necessary to inspect the adhesion state by attaching a suction cup to each adhesion location. Since the waterproof sheet is bonded to the waterproof base at the entire periphery of the laying area and at many locations in the laying area surrounded by the rim, the work of inspecting all the bonded parts is complicated and takes a long time. There was a problem. In addition, when checking against design books (work drawings for waterproof groundwork), it is necessary to mark the inspected portions of the waterproof sheet for all the bonded portions in order to prevent leakage of inspection, but this work is also complicated.

  The subject of this invention is providing the inspection method which can confirm the adhesion | attachment state of the waterproof sheet laid on the waterproof base | substrate and a waterproof base | substrate on a waterproof floor surface by the said insulation method by a simple process.

The present invention relates to a building in which a waterproof sheet is continuously laid on a waterproof base, and the waterproof base and the waterproof sheet are partially bonded in a predetermined pattern including the peripheral portion of the waterproof sheet laying region. A method for inspecting an adhesive state between the waterproof sheet and a waterproof base on a waterproof floor surface,
An opening is provided in the waterproof sheet,
Sending gas between the waterproof base and the waterproof sheet from the opening above to lift the waterproof sheet part that is not bonded to the waterproof base,
The adhesion state between the waterproof base and the waterproof sheet is determined based on the consistency between the portion of the waterproof sheet that does not float and the predetermined pattern.

  In this invention, it is included as a preferable aspect respectively that the said gas is colored and the said waterproofing base | substrate is equipped with the fixing tool, and the waterproof sheet is adhere | attached on this fixing tool. In addition, it is preferable that a fixing tool is flat form.

  According to the present invention, since the entire laid waterproof sheet is lifted by gas, it is possible to determine at a glance whether or not the waterproof sheet is adhered to the entire waterproof floor surface, and the operation is simple and performed in a short time. Can do. Further, since the floating state of the waterproof sheet can be visually recognized in a predetermined pattern, only the detected adhesion failure portion needs to be marked on the waterproof sheet, and verification with the design book is unnecessary. Further, by coloring the gas sent between the waterproof sheet and the waterproof base, it is possible to easily detect a damaged portion of the waterproof sheet such as a pinhole or a poorly bonded portion between the waterproof sheets. Further, when the waterproof base is provided with a fixing tool, and the waterproof sheet is bonded to the fixing tool, it is possible to detect the fixing failure of the fixing tool to the waterproof base.

  The waterproof floor on which the inspection method of the present invention is implemented is formed by continuously laying a waterproof sheet on a waterproof base and partially bonding the waterproof sheet and the waterproof base. In the present invention, “laying the waterproof sheets continuously” means that the waterproof sheets are continuous without being interrupted in the area where the waterproof sheets are laid. Usually, the waterproof sheet is provided as a long sheet having a predetermined width at the construction site of the building under construction, a plurality of sheets are arranged in parallel according to the width of the laying area, and adjacent to each other as shown in FIG. The end portions in the width direction of the sheets 1a and 1b to be performed are partially laid on each other, and the overlapping portion 41 is bonded. In the present invention, “continuous” means that the polymerized portion 41 is not non-adhered.

  In the waterproof floor according to the present invention, the waterproof sheet and the waterproof base are bonded in a predetermined pattern including the peripheral edge of the area where the waterproof sheet is laid. In a general insulating method, a waterproof sheet and a waterproof base are bonded via a fixing tool attached to the waterproof base. Although the present invention is not limited to the form using such a fixing tool, a preferred embodiment of the present invention will be described below by taking the form using the fixing tool as an example.

  1 (a) and 1 (c) are schematic cross-sectional views of a preferred construction example of a waterproof floor surface on which the inspection method of the present invention is implemented, (a) is a waist wall type veranda, and (c) is a waist An open veranda with no walls. In such a veranda structure, as a waterproof base, a heat insulating material 7 is laminated on a lightweight cellular concrete board (ALC board) 4 which is a floor board forming a slab of a building frame, and in the laying area of the waterproof sheet 1, A disk 2 as a fixing tool is attached to the heat insulating material 7 with screws 3. In other words, the disk 2 has both the function of adhering to the waterproof sheet 1 and the function of passing through the heat insulating material 7 with the screw 3 and fixing it to the ALC plate 4. FIG. 5 shows a configuration example of the disk 2 and the screw 3. As shown in FIG. 5 (a), the disc 2 of this example is provided with a resin layer or a waterproof sheet piece 52 on a base material 51 formed by cutting a flat steel material into a disc shape, and at the center thereof. Is provided with a hole 53 through which the leg of the screw 3 penetrates and the head does not penetrate. Therefore, as shown in FIG. 5B, the disc 2 is attached to the ALC plate 4 and fixed to the hole through the leg portion of the screw 3.

  Further, in the waterproof base corresponding to the peripheral portion of the laying region of the waterproof sheet 1, the heat insulating material 7 is laminated on the beam member 6 having a steel structure, and the prefabricated steel plate 8 as a fixing tool is further attached to the screw 3 on the heat insulating material 7. It is fixed to the ALC plate 4 by.

  The prefabricated steel plate 8 has a waterproof sheet piece attached to a base plate whose cross section is bent in an approximately L shape so that a flat steel plate is attached along the shape of a wall floor parting portion, a roof eaves tip portion, or the like. As shown in FIG. 1 (a), a waist wall type veranda is used that is attached to the rising side surface of the waist wall 5 with the L-shaped vertical side facing upward, and FIG. 1 (c). On the rooftop or open veranda without the waist wall 5 as shown in Fig. 1, the type with the L-shaped vertical side facing downward is used. FIG. 6A shows an example of the configuration of the prefabricated steel plate 8 used in the waist wall type veranda. In the figure, 61 is a base plate, 62 is a resin layer or waterproof sheet piece, and 63 and 64 are fixing holes for mounting. FIG. 6B is a perspective view showing a state in which the prefabricated steel plate 8 and the waterproof sheet 1 of FIG.

  The contact surface of the disk 2 and the prefabricated steel plate 8 with the waterproof sheet 1 is flat and is provided with a resin layer or a waterproof sheet piece that is dissolved by a predetermined solvent. The waterproof sheet 1 is also formed of a material that is dissolved by the solvent. Accordingly, by interposing the solvent between the resin layer or waterproof sheet piece and the waterproof sheet 1, the resin layer or waterproof sheet piece and the waterproof sheet 1 can be dissolved and integrated to be bonded. As a material of the waterproof sheet 1 and the resin layer or the waterproof sheet piece, for example, vinyl chloride is preferably used. However, in the present invention, it is not limited to this, and is preferably a sheet-like material generally used for an insulation method. Used.

  In the waterproof floor surface of this example, a heat insulating material 7 is laid on the ALC plate 4 and the beam material 6, then the prefabricated steel plate 8 is attached to the beam material 6 with screws (not shown), and the disk 2 is attached with the screws 3 to the ALC plate 4. After being attached, the waterproof sheet 1 is laid on the entire laying area. As shown in FIG. 4, the adjacent waterproof sheets are partially overlapped with each other and bonded to each other. At the periphery of the laying region, a solvent is applied to the prefabricated steel plate 8 to end the waterproof sheet 1. The parts are placed and pressed to adhere to each other. For the disk 2, a solvent is applied to the disk 2 in advance before the waterproof sheet 1 is laid, or a solvent is applied between the waterproof sheet 1 and the disk 2 using a syringe from above the waterproof sheet 1. Inject, press and weld together.

  In the present invention, the adhesive form between the waterproof base and the waterproof sheet and the adhesive form between the waterproof sheet 1 and the fixing tool (the resin layer of the prefabricated steel plate 8 or the waterproof sheet pieces 52 and 62) are welded with the above-mentioned solvent. The present invention is preferably applied to a form using an adhesive, a form that is fused and integrated (heat fusion) by applying heat, and a form of adhesion using electromagnetic ultrasonic waves.

  In addition, the building form of the building to be waterproofed is not limited to the steel structure, but may be RC or wooden, and the material and layer structure of the floor board and waterproof base are not particularly limited.

  Next, the inspection method of the present invention is performed.

  In the present invention, an opening is provided in the waterproof sheet 1, and gas is sent between the waterproof sheet 1 and the waterproof base through the opening. Air may be used as the gas. As described above, the waterproof floor for carrying out the inspection method of the present invention has the waterproof sheet 1 bonded to the waterproof base at the peripheral portion of the laying region, and dots in continuous non-adhesive portions surrounded by the peripheral portion. There is an adhesive part in the shape. For example, FIG. 7 is a construction diagram of waterproof base construction, in which a waterproof base, which is a heat insulating material 7 of a standardized size, is allocated and arranged, and fixing tools (disks 2) are arranged at regular intervals. Therefore, as shown in FIG. 1 (b), when a gas such as air is sent between the waterproof sheet 1 and the waterproof base, the waterproof base and the waterproof sheet 1 of the non-adhesive portion in the laying region of the waterproof sheet 1 A continuous space 11 is formed between the two. Since the space 11 is completely sealed except for the opening through which the gas is fed, there is no gas escape path, and the formation of the space 11 forms a clear boundary between the bonded portion and the non-bonded portion. Can be easily detected visually. FIG. 3A is a plan view of the waterproof floor surface in FIG. 1A when the bonding state is good, and broken lines 31 and 32 are boundaries between the bonded portion formed by the space 11 and the non-bonded portion. . In addition, as an opening part which sends in gas, although it does not specifically limit, as shown in FIG.4 (b), in the superposition | polymerization part 41 which overlaps and adhere | attaches the edge parts of adjacent waterproof sheet 1a, 1b partially, It can be set as the opening part 42 without adhering.

  FIG. 2 shows an example of poor adhesion between the waterproof sheet 1 and the waterproof base on the waterproof floor shown in FIG. FIG. 2A shows a case where the adhesion portion is insufficient, and reference numerals 21 and 22 denote adhesion failure portions. In this case, when the inspection method of the present invention is carried out, as shown in FIG. 3B, the broken lines 31 and 32 do not show the original shape [FIG. The portions 21 and 22 can be detected.

  In addition, when the disk 2a on the left side of FIG. 2B is not adhered to the waterproof sheet 1 due to the application of the solvent, the disk 2b on the right side of the sheet has screws 3 for attaching the disk 2b to the ALC plate 4. In any case, as shown in FIG. 3C, the boundary between the bonded portion and the non-bonded region that should be detected at the time of inspection is not detected. In addition, even when the disk 2 is attached, the boundary that should be detected is not detected.

  Since the adhesion part in the insulation method is provided in a predetermined pattern designed so that the fixing strength between the waterproof sheet 1 and the waterproof base is uniform as a whole, the pattern and the adhesion part indicated by the broken lines 31 and 32 Therefore, adhesion failure can be easily detected. Since such patterns are standardized and have regularity, in particular, it is possible to detect at a glance when looking at the entire waterproof floor surface, such as missing of a bonded portion where no boundary is detected as shown in FIG. Is done. That is, unlike the conventional inspection method, it is not necessary to inspect every bonded portion. Further, when an adhesion failure as shown in FIGS. 3B and 3C is detected, the waterproof sheet 1 may be marked and repaired individually.

  Incidentally, the repair work when the adhesive part as shown in FIG. 3B is insufficient or when the adhesive leakage occurs as in the disk 2a of FIG. 3C is not particularly limited, but is waterproof. A solvent may be injected between the waterproof sheet 1 and the disk 2 with a syringe from above the sheet 1 and reattached. Further, when the screw 3 is removed from the ALC plate 4 or the disc 2 is not attached like the disc 2b in FIG. 3C, the waterproof sheet 1 around the disc 2b is removed. What is necessary is just to restore | repair by the method of cut | disconnecting, attaching the disk 2b newly, adhere | attaching the waterproof sheet 1, and closing the cut location of the waterproof sheet 1. FIG.

  Moreover, this invention can also detect that the waterproof sheet 1 has a damaged part, such as a pinhole, or that a defect has occurred in an adhesive part between the waterproof sheets 1. That is, in such a case, the gas sent between the waterproof sheet 1 and the waterproof base is spilled outside from the damaged part or the poorly adhered part, and the waterproof sheet 1 is swollen without the space 11 being sealed. The state is not well formed.

  Furthermore, by coloring the gas sent between the waterproof sheet 1 and the waterproof base, it is possible to visually detect the gas leaking to the outside, and easily detect such a damaged portion or a poorly bonded portion. be able to. Specifically, the method of coloring the gas can be carried out, for example, by putting water in a bucket, and submerging the smoke cylinder in the water to send the generated smoke to the air intake of the blower.
