Description

  The present invention relates to a watertight test apparatus and a watertight test method for a glazing channel for evaluating the watertightness of the glazing channel in a shoji configured by attaching a heel to the peripheral portion of the plate-like body via the glazing channel. About.

  When evaluating the watertight performance of a sash, the sash is actually designed and prototyped, and a shoji is inserted into the prototype sash, and this is based on the watertight performance test method for fittings in accordance with JIS A1517 (1996). Test. If the target performance cannot be obtained due to the water leakage status of the test result, the design and trial production are repeated. A technique for predicting the watertight performance of a sash is disclosed in Patent Document 1 in order to reduce the repetition of such design, prototyping, and testing.

On the other hand, JIS A4706 (2000) and JIS A4702 (2000) stipulate the watertightness grade (W-1 to W-5) and performance (determination criteria) of the sash. In the watertight performance test of JIS A1517 (1996), a pressure (pulsation pressure) corresponding to the above grade is applied to the specimen for 10 minutes, and 4 l / m ³ of water per minute is sprayed on the specimen, Evaluate the watertight performance of the sash based on the water leakage from the sash. For example, in a sash of grade W-4 using an urban building as a guide, a pressure (median value 350 Pa) having an upper limit value of 525 Pa and a lower limit value 175 Pa is applied to the specimen at a cycle of 2 seconds.
JP 2002-350274 A

  However, the watertight performance test method specified by JIS is an evaluation test method for the entire sash comprising a shoji and a window frame, and is not a watertight test method for a shoji alone, but a test method that can evaluate a glazing channel alone. Absent. The shoji is configured by attaching a heel to a peripheral portion of a glass plate through a glazing channel made of an elastic material such as resin or rubber. For this reason, a gap is generated between the glass plate and the glazing channel and between the glazing channel and the ridge due to the pressure during the watertight performance test, and water leaked from the gap other than between the shoji and the window frame. It may affect the overall evaluation of the sash. Therefore, it is necessary to provide a glazing channel presumed to satisfy the grade specified by JIS by evaluating the watertight performance of the shoji, that is, the watertight performance of the glazing channel in close contact with the glass plate and the scissors alone. It was.

  The present invention has been made in view of such circumstances, and it is an object of the present invention to provide a watertight test apparatus and a watertight test method for evaluating a glazing channel among glass, glazing, and glazing channels constituting a shoji. And

  In order to achieve the above object, the present invention provides a watertight test apparatus for evaluating the watertightness of a glazing channel of a shoji configured by attaching a heel to a peripheral portion of a plate-like body via a glazing channel. A container provided with a heel support member that accommodates the shoji and that is in close contact with the fold of the accommodated shoji and supports the heel in a watertight state, and the sash supported by the heel support member. A pressure member that abuts on the plate-like body and pressurizes the plate-like body in a direction orthogonal to the surface of the plate-like body, and a water supply that supplies water to a space between the container and the pressure member A glazing channel water-tightness test apparatus comprising: a section; and a water level measuring section that is provided in the container and measures the water level of the water supplied to the container.

  In order to achieve the above object, the present invention uses the watertight test device for a glazing channel of the present invention, houses a shoji in a container of the watertight test device, and supports the shoji of the shoji in a watertight state by a heel support member. A pressure member is placed on the plate-like body of the shoji, a predetermined amount of water is supplied from a water supply unit to the space between the container and the pressure member, and the water supplied to the container The water level is measured by a water level measuring unit, the plate-like body of the shoji is further pressurized by the pressure member in a direction perpendicular to the surface, and after the plate-like body is pressed by the pressure member, the predetermined time elapses. Provided is a watertight test method for a glazing channel, characterized in that the watertightness of the glazing channel is evaluated based on a change in the water level measured by a water level measuring unit.

  According to the present invention, when the plate-like body of the shoji is pressed by the pressurizing member, if the plate-like body is bent and a gap is generated between the plate-like body and the glazing channel, water is discharged from the gap. As it leaks, the water level in the container drops. The water level is measured by a water level measuring unit such as a scale attached to the side surface of the container or the side surface of the pressure member. And the watertightness of a glazing channel is evaluated based on the change of the water level after progress for a predetermined time after pressurization, that is, based on the amount of water leakage. In order to set the evaluation standard, for example, in a watertight performance test method specified in JIS A1517 (1996), a test was performed using a glazing channel determined to be acceptable in a predetermined grade, and this glazing channel was used. The change in water level is set as an evaluation standard. This evaluation standard serves as an index for evaluating the water tightness of a newly prototyped glazing channel. Such evaluation criteria are preferably obtained for each grade.

Further, according to the present invention, the load applied from the pressure member to the plate-like body is determined from the maximum load applied to a window of a predetermined size, the pressure receiving area of the window, and the length of the glazing channel of the window. It is preferable that the load be calculated by multiplying the line load by the length of the glazing channel of the plate-like body .
According to the present invention, even if the shoji as a test body is downsized, the test can be performed under the same load condition as a full-size window. By reducing the size of the shoji, the watertight test device becomes compact, so that the test device can be handled easily and the test can be carried out smoothly.

  Further, according to the present invention, the container is a cylindrical container provided with a container lower part on which the lower surface of the shoji fold is placed, and a flange portion that is in close contact with the upper surface of the jar in a watertight state via a seal portion. Preferably, the heel support member is configured by the seal portion and the flange portion, and the water is supplied to a space between the container upper portion and the pressure member. That is, the container is constituted by a container lower portion on which the lower surface of the shoji ridge is placed and a cylindrical container upper portion having a flange portion that is in close contact with the upper surface of the heel in a watertight state via a seal portion. The shoji support member configured by the seal portion and the flange portion supports the shoji of the shoji in a watertight state, and supplies the water to the space between the container upper portion and the pressurizing member.

  In the present invention for evaluating the watertight performance of the glazing channel, it is necessary to cause the water supplied to the container to leak only from the gap formed by the three members of the plate-like body, the glazing channel, and the ridge. It is necessary to support the bag in a watertight state in the container. For this reason, the container is provided with a ridge support member that supports the ridge in a watertight state. In this scissor support member, as in the present invention, the container is divided into a container lower part and a container upper part, and by adopting a configuration in which the scissors are sandwiched by the seal part of the flange part formed on the container upper part and the container lower part, A heel support member having a simple structure can be provided. Moreover, in order to increase the clamping force with respect to the bag, it is desirable to clamp the lower part of the container and the flange part of the upper part of the container with a clamp member to hold the bag with pressure. When the container is divided into two in this way, water is supplied to the space between the upper part of the container and the pressurizing member, so that it is not necessary to supply water to the entire container, and the amount of water used can be reduced. The watertight test device can be reduced in weight.

  Further, according to the present invention, the pressing member includes a cylindrical pressing body placed in a watertight state on the upper surface of the plate-like body of the shoji through a seal portion, and a weight mounted on the pressing body. It is preferable that the water is supplied to a space between the pressing body and the upper part of the container. That is, the pressing member is constituted by a cylindrical pressing body placed in a watertight state on a top surface of the plate-like body of the shoji through a seal portion, and a weight mounted on the pressing body, and the pressing member After placing the body on the upper surface of the plate-like body, the water is supplied to the space between the pressing body and the upper part of the container, and the weight is mounted on the pressing body.

  According to this invention, a pressurizing member is comprised from a cylindrical press body and a weight, and water is supplied to the space between this press body and a container upper part. When the pressing body is placed on the upper surface of the plate-shaped body, the seal portion attached to the lower peripheral portion of the pressing body is in close contact with the upper surface of the plate-shaped body in a water-tight state. Do not penetrate inside. Thereby, the usage-amount of water is reduced and the weight reduction of a water-tightness testing apparatus can be achieved as mentioned above. In addition, in order to improve the water-tightness with respect to the plate-shaped body of a seal part, it is preferable to supply water, after putting a reserve weight on a press body. Thereafter, a weight for further pressurizing the plate-like body is placed. This improves the reliability of the experimental results.

  As described above, according to the present invention, it is possible to provide a water tightness test apparatus and a water tightness test method for evaluating glazing channels constituting a shoji.

  Hereinafter, preferred embodiments of a watertight test apparatus and a watertight test method for a glazing channel according to the present invention will be described with reference to the accompanying drawings.

  First, before describing the watertight test apparatus according to the embodiment based on the drawings, an outline of the apparatus will be described. This water-tightness test apparatus applies a load corresponding to the upper limit value of the pulsation pressure specified in JIS A1517 (1996) to the glass plate of the shoji, and uses the water pressure corresponding to the upper limit value as the hydraulic head pressure to the peripheral portion of the glass plate ( This is a device for loading the glass plate and the glazing channel). The pressurization test time by this water-tightness test apparatus is 10 minutes at maximum. Further, when 10 minutes elapse, the glazing channel of the water level change up to the specified displacement is evaluated as acceptable. The pressurization test in this apparatus is set to a stricter condition than the watertight test (pulsation test) condition defined in JIS A1517 (1996). That is, the water tightness test conditions specified in JIS A1517 (1996) pressurize the upper limit value and lower limit value of pulsation pressure with a sine wave with a cycle of 2 seconds for 10 minutes, and the pressurization time of the upper limit value is 5 minutes. Because it is only. Specifically, in the case of the W-4 grade defined in JIS A4706 (2000) and JIS A4702 (2000), the upper limit value of the pulsation pressure is 525 Pa and the lower limit value is 175 Pa. A load corresponding to the upper limit value of 525 Pa is applied to the glass plate for 10 minutes. In addition, this load is a load obtained by converting a total load applied to a window of a predetermined size into a linear load applied to the glazing channel, and does not use a full-size window but uses a shredded test piece. This contributes to downsizing and handling of the apparatus.

  FIG. 1 is a perspective view showing an appearance of a watertight test apparatus 10 according to an embodiment, FIG. 2 is a longitudinal sectional view of the watertight test apparatus 10, and FIG. 3 is a test body to be tested by the watertight test apparatus 10. It is the perspective view which showed the shoji 12 of. As shown in FIG. 4, the shoji 12 shown in FIG. 4 is provided on the four side edges of a rectangular glass plate 14 that is a plate-like body via linear, resin or rubber glazing channels 16, 16. , And is constructed by mounting metal cages 18, 18... Shown in FIG.

  FIG. 6 is a cross-sectional view of the main part of the shoji 12 in which the scissors 18 are attached to the glass plate 14 via the glazing channel 16, and the soft lip portions 16A and 16A of the glazing channel 16 are elastically placed on the surface side of the glass plate 14. It is shown that they are in close contact. In the figure, as the glass plate 14, a double-layer glass formed by mounting two glass plates 14A and 14A via spacers 15 is illustrated, but is not limited to a double-layer glass. It may be a sheet of glass. Moreover, although the glass plate 14 was illustrated as a plate-shaped body, it is not limited to this, A plate-shaped body like resin-made panel materials may be sufficient.

  On the other hand, as shown in FIGS. 1 and 2, the water-tightness test apparatus 10 includes a container 20, a pressurizing member 22, a water supply unit 24, a scale (water level measuring unit) 26, and the like.

  The container 20 includes a container lower part 28 and a container upper part 30. The container lower part 28 and the container upper part 30 are both molded articles made of a transparent resin material, and the level of water supplied to the container 20 can be seen through from the outside of the container 20. In addition, since the water level should just be visible from the outer side of the container upper part 30 so that it may mention later, the container lower part 28 is not limited to the molded article by a transparent resin material.

  The container lower part 28 is configured in a rectangular shape so that the rectangular shoji 12 can be placed, and a drain pipe 32 is provided in the container lower part 28. By opening a valve (not shown) of the drain pipe 32, the water leaked from the shoji 12 and accumulated on the upper surface of the container lower part 28 is drained to the outside of the container lower part 28. In order to facilitate the discharge, the drain pipe 32 is provided at the corner of the container lower part 28, and the gradient of the container lower part 28 with respect to the horizontal plane is preferably 0.1 to 0.5%, more preferably 0.14 to 0.2%. It is preferable to raise the angle facing the corner of the container lower part 28 where the drain pipe 32 is located so as to be higher. In addition, although the flat container lower part 28 is shown in FIG. 2, the shape of the container lower part 28 is not limited to this. For example, it is good also as a structure which comprises the container lower part 28 in the box shape with which the upper surface was open | released, and formed the square frame-shaped support surface which supports only the collars 18, 18, ... of the shoji 12 inside this. Further, the inside of the support surface may be a concave portion of a water pool, and a drain pipe communicating with the concave portion may be projected outside from the lower surface of the lower portion of the container.

  The container upper part 30 is formed in a rectangular tube shape, and a flange part 34 protruding in the horizontal direction is formed around the lower part thereof. The outer peripheral shape of the flange portion 34 is substantially the same size and the same shape as the outer peripheral shape of the container lower portion 28. A seal portion 36 is stuck around the lower surface of the flange portion 34, and this seal portion 36 is brought into contact with the flanges 18, 18... Of the shoji 12 placed on the container lower portion 28. The seal portion 36 and the flange portion 34 of the container upper portion 30 constitute a heel support member, and the container upper portion 30 is in close contact with the upper surfaces of the ridges 18, 18. Further, in order to improve the water tightness between the seal portion 36 and the flange 18, the container lower portion 28 and the flange portion 34 of the container upper portion 30 are clamped by the clamp members 38, 38, and the flanges 18, 18. It is desirable to hold the pressure between the upper part 30 of the container. Since this clamp member 38 has a well-known structure, its description is omitted here.

  Further, a scale 26 with a scale in mm is attached to the side surface of the container upper portion 30. The scale 26 measures the water level L from the surface of the glass plate 14 of the shoji 12 supported by the container 20, and is attached to the side surface of the container upper part 30. As a method for measuring the water level, water 40 having a predetermined water head pressure is supplied from the water supply unit 24 to the container 20, and the water level measured at this time is confirmed on the scale 26 as a reference water level. There is a method of viewing the displacement after the test time has passed on the scale 26. Moreover, you may make it measure on the scale 26 so that it may become a predetermined | prescribed water head pressure. Note that the scale 26 may be attached to the side surface of the pressurizing member 22 that supplies water instead of the side surface of the container upper portion 30.

  In the watertight test apparatus 10 according to the embodiment for evaluating the watertight performance of the glazing channel 16, the water 40 supplied from the water supply unit 24 to the container 20 is placed between the glass plate 14 and the glazing channel 16, and the ridge 18 and the glazing channel 16. It is necessary to leak water only from the gap between the two. For this purpose, it is necessary to support the collar 18 of the shoji 12 in the container 20 in a watertight state. For this reason, the container 20 supports the collar 18 in the watertight state as described above. 36). In this eaves support member, the container 20 is divided into a container lower part 28 and a container upper part 30 as in the watertight test apparatus 10 of the embodiment, and the seal part 36 of the flange part 34 formed in the container upper part 30 and the container lower part By adopting a configuration in which the heel is clamped by the heel 28, a heel support member having a simple structure can be provided. Thus, when the container 20 is divided into two, the water 40 is supplied to the space between the container upper part 30 and the pressurizing member 22 described later. Accordingly, it is not necessary to supply water to the entire container 20 and the amount of water used can be reduced, so that the water tightness test apparatus 10 can be reduced in weight. Also, from the viewpoint of measuring the amount of water leakage, if the amount of water is large, it becomes insensitive to changes in the water level, so it is better to supply water to the space.

  The pressurizing member 22 pressurizes the glass plate 14 in a direction perpendicular to the surface of the glass plate 14 of the shoji 12 supported by the container 20, and is a cylindrical pressing body 42 and a predetermined mounted on the pressing body 42. It consists of a plurality of weights 44, 44. Note that water 40 is supplied to the space between the pressing body 42 and the container upper portion 30.

  The pressing body 42 is formed in a rectangular tube shape, and a seal portion 46 is attached to the lower edge portion thereof as shown in FIG. 7, and the pressing body 42 is in a watertight state to the glass plate 14 via the seal portion 46. Placed. Further, a weight placing plate 48 is attached to the inside of the pressing body 42, and weights 44, 44... Are stacked on the weight placing plate 48 in the vertical direction.

  As described above, the pressing member 42 is constituted by the pressing body 42 and the weights 44, 44..., And water 40 is supplied from the water supply unit 24 to the space between the pressing body 42 and the container upper portion 30. When the pressing body is placed on the upper surface of the plate-shaped body, the seal portion 46 of the pressing body is brought into close contact with the upper surface of the glass plate 14 in a watertight state, so that the supplied water 40 does not enter the pressing body 42. Thereby, the usage-amount of the water 40 is reduced and the weight reduction of the watertight test apparatus 10 is achieved. In order to improve the water tightness of the seal portion 46 to the glass plate 14, it is preferable to supply the water 40 after placing a spare weight (a mass of about 5.7 kg) on the pressing body 42. Thereafter, by placing weights 44, 44... For pressing the glass plate 14 on the weight mounting plate 48 of the pressurizing body 42, the reliability of the experimental results is improved.

  Next, a watertight test method using the watertight test apparatus 10 configured as described above will be described.

  First, the container 20 is divided into a container lower part 28 and a container upper part 30, and the shoji 12 is placed on the divided container lower part 28, and the flange part 34 of the container upper part 30 is attached to the upper surface side of the collar 18 of the shoji 12. The contact is made through the seal portion 36. If necessary, the container lower portion 28 and the flange portion 34 of the container upper portion 30 are clamped by the clamp members 38, 38..., And the flanges 18, 18. As described above, the shoji 12 is accommodated in the container 20 of the watertight test apparatus 10.

  Next, the pressing body 42 of the pressing member 22 is placed on the glass plate 14 of the shoji 12 without pressing the glass plate 14.

  Next, a predetermined amount of water 40 is supplied from the water supply unit 24 to the space between the container upper part 30 and the pressing body 42, and the water level is measured by the scale 26.

  Next, weights 44, 44... Are placed on the weight placing plate 48 of the pressing body 42, and the glass plate 14 of the shoji 12 is pressed in a direction perpendicular to the surface.

  Then, after pressurizing the glass plate 14 with the weights 44, 44..., The change in the water level measured by the scale 26 after a predetermined time has elapsed is read, and the water tightness of the glazing channel 16 is evaluated based on the changed water level.

  According to the water-tightness test method using the water-tightness test apparatus 10, when the glass plate 14 of the shoji 12 is pressurized by the weights 44, 44,..., The glass plate 14 (the upper surface side glass plate 14A) is shown in FIG. By bending downward as described above, gaps are formed between the glass plate 14 and the glazing channel 16 and between the ridge 18 and the glazing channel 16. Then, the water 40 leaks from the gap, the water level of the water 40 in the container upper part 30 is lowered, and the water level is measured by the scale 26.

  In the water-tightness test method, the watertightness of the glazing channel 16 is evaluated based on the change in the water level after a predetermined time has elapsed after pressing (maximum 10 minutes), that is, based on the amount of water leakage. In order to set the evaluation standard, for example, in a watertight performance test method specified in JIS A1517 (1996), a test was performed using a glazing channel determined to be acceptable in a predetermined grade, and this glazing channel was used. The change in water level is set as an evaluation standard. This evaluation standard serves as an index for evaluating the water tightness of the newly prototyped glazing channel 16. Such evaluation criteria are acquired for each grade.

  In the watertight test method, the load applied from the pressure member 22 to the glass plate 14 is set to a load obtained by converting the total load applied to the window of a predetermined size into the linear load applied to the glazing channel 16. Thereby, even if the shoji 12 which is a test body is reduced in size, the test can be performed under a load condition equivalent to a full-size window. If the shoji 12 is downsized, the watertight test apparatus 10 is also compact, so that the test apparatus can be handled easily and the test can be carried out smoothly.

  The above-described watertight test method by the watertight test apparatus 10 will be further clarified by the embodiments described below.

  In carrying out the test method of the present invention, the following full size sash sizes and loads were assumed.

Sash type: Sliding window
Sash maximum size (mm): 1280 x 2200
Pressure receiving area B (m ² ): 2.816
Grazing channel length C (mm): 6960
Line load D (Pa · mm) applied to the glazing channel: 0.212
However, D is calculated | required by (525Pa which is the maximum load of W-4 grade) xB / C.

  As a test for the sash, the following test bodies (shoji) were prepared, and the test load was determined.

Glass plate size (mm): 350 x 350
Grazing channel length E (mm): 1400 (350 × 4)
Grazing channel material: PVC / Rubber load W applied to the shoji for testing W: 296.8 Pa (30.3 kgf / m ² )
However, W is a load obtained by converting a total load applied to a window of a predetermined size into a linear load applied to the glazing channel, and is obtained by D × E.

  Using the test apparatus of the present invention, the test was performed as follows on the above test body.

Next, the load W was applied to the test body by actually using the test apparatus of the present invention. that time,
The initial water level was poured from the glass plate to the water head pressure level (52.5 mm), and the change in the water level was measured in units of 1 minute. The test time was the same as the watertight performance test for 10 minutes, and the determination was made based on the water level when 10 minutes passed. The water level of 1 mm is 9.81 N (1 kgf: head height = water pressure).

  Evaluation of the hermetic performance of the test specimen was performed as follows.

  First, when the soft glazing channel of a general sash maker (passing the airtight test in the wind tunnel test) was confirmed with this test apparatus, the water level was approximately 0.5 mm to 45.5 mm. In this case, the performance of the sash can be ensured even if the amount of water entering between the glass and the glazing channel is large because the sash has the ability to quickly drain the incoming water.

  On the other hand, a watertight performance test (wind tunnel test) was conducted, and in particular, a glazing channel manufactured by Asahi Glass Co., Ltd. attached to a sash that passed the test with little water leakage from the sash was confirmed with this testing machine. As a result, the change in the water level was about 0 to 2 mm. Based on this, this 2 mm was used as a criterion, and a case where the water level changed below this value was determined to be acceptable.

  As described above, by using this water tightness test apparatus, it is possible to contribute to standardization of glazing channel design for satisfying the grade performance defined by JIS.
