Description

  In the present invention, two ceramic exterior plates having end faces inclined at an angle of 45 ° with respect to the design surface are bonded to each other at the inclined end faces, and used in the corner of the building. It relates to a corner member.

A ceramic industry corner member used for a corner of a building is cut at a predetermined position of a ceramic exterior panel of a predetermined length, for example, by cutting the center into a substantially V shape at an angle of 45 ° to the design surface. It is manufactured by producing two ceramics-type exterior plates having inclined end faces and bonding the end faces of these two ceramic-type exterior plates. Such a ceramics-type projecting corner member has an exterior plate design surface on the front side and an exterior plate back surface on the inside.
In addition, when producing two ceramics-type exterior plates, columnar end materials having an isosceles right-angled triangle cross section are discharged as industrial waste.

The widths of the two ceramic-type exterior plates are usually equal. For example, the width (back surface width L) measured on the inner surface side of the ceramics-type projecting corner member is 75 to 120 mm when the thickness t of the ceramics-type exterior plate is 12 mm, 75 to 120 mm when the thickness t of the ceramics-type exterior plate is 15 mm, When the thickness t of the ceramic-type exterior plate is 18 mm, 75 to 146 mm is typical (see, for example, Non-Patent Document 1).
In recent years, ceramic-type projecting corner members having a large back surface width have also been manufactured and used.

  By the way, ceramic corners with a large back surface width are, for example, places that require ceramic corners that cover from the corners of the building to the studs, or normal ceramics attached to the corners. It is used for a part that is attached to the ceramics-type exterior plate so as to cover an end portion of the exterior plate on the corner side.

  However, such ceramic ceramic corner members with a large back surface width are damaged in storage, packing, transportation, unpacking, construction, etc. after manufacturing compared to the ceramic corner member having a typical back surface width described above. There has been a disadvantage that it is necessary to be careful in handling.

  An object of the present invention is to provide a ceramic industry-type corner member that can reduce such inconvenience.

As shown in FIG. 1, the inventors of the present invention have a ceramics-type projecting corner member 50 in which the thickness t of the ceramics-type exterior plates 15, 16 is 12 mm and the back surface widths L ₁ and L ₂ are both 165 mm, that is, already sufficient for handling. Prepare a ceramic-type projecting corner member that must be noted as sample 1, ground the tip of one ceramics-type exterior plate 15 on a flat horizontal surface at an angle of 45 °, and place it on the tip of the other ceramic-type exterior plate 16 A test was performed in which a force F directed vertically downward was applied.
The force F when the sample 1 was broken was measured, and this measurement was repeated 5 times to obtain an average value F _X of the force F.
Then, the fracture strength P = F _X / t was calculated based on the average value F _X , and P = 1.64 N / mm.

Next, a ceramic-type projecting corner member 10 (FIG. 2) in which a ceramic-type columnar member is bonded to a right-angled corner portion on the back side of the place where two ceramic-type exterior plates are bonded is prepared as Sample 2. When a test similar to that of Sample 1 was performed and the breaking strength P was calculated, P = 1.92 N / mm. Note that a code shown in FIG. 2, ceramic-based external corner member _{10, L 1 = L 2 = 165mm} , t = 12mm, H 1 = H 2 = 115mm, W 1 = W 2 = 17.0mm (= 12 × 2 ^1/2 ).
The sample 2 was less likely to break when tested for storage, packing, transportation, unpacking, construction, and the like. In other words, it was found that t = 12 mm and the back surface widths L ₁ and L ₂ can be handled in the same manner as a ceramics-type projecting corner member having 75 to 120 mm.

  Based on the results of Sample 1 and Sample 2, from the viewpoint of handleability, P = 1.92 N / mm or more, even if it is a ceramic-based columnar member in which a ceramic columnar member is not bonded to a right-angled corner. It was found that there was no need for reinforcement.

Subsequently, a breakage test similar to that of Samples 1 and 2 is performed on Samples 3 to 5 in which the ceramic columnar members are not bonded to the right-angled corners, and the breaking strength P = F _X / t is calculated based on the average value F _X of the force F. Calculated.
Note that Sample 3 two ceramic based exterior plate thickness t backside width _{L 1} and _{L 2} both are 75mm in 12mm of, the sample 4 is the back surface width _{L 1} thickness t of the two ceramic based exterior plate with 15mm And L ₂ are both 75 mm, and Sample 5 has two ceramics-type exterior plates with a thickness t of 18 mm and back surface widths L ₁ and L ₂ of 75 mm.
As a result, the breaking strength of sample 3 was P = 3.82 N / mm, the breaking strength of sample 4 was P = 4.21 N / mm, and the breaking strength of sample 5 was P = 4.61 N / mm.

And based on the test results of these samples 3 to 5, for each case of t = 12, 15, and 18 mm, the ceramics-type projecting corner member of the back surface width L ₁ (≧ L ₂ ) (the ceramics-based columnar member is not bonded) Fracture strength P was calculated. The results are shown in Table 1 together with L ₁ / t ^1/2 . The unit of L _{1 and} t is mm, and the unit of P is N / mm.

Since it has already been known that the ceramics-type projecting corner member having P = 1.92 N / mm or more does not need reinforcement, according to Table 1, for example, when the thickness t of the ceramics-type exterior plate is 12 mm, the back surface width L It can be seen that there is no need to reinforce the ceramic-type projecting corner member with ₁ being 146 mm.
And even if it is a case where the thickness t of the ceramics type exterior board which comprises a ceramics type cornering member is different, the present inventors attach the ceramics type cornering member which should adhere a ceramics type columnar member to a right-angled corner part. In order to make an evaluation, the inventors have focused on the fact that the evaluation should be made as L ₁ / t ^1/2 based on the thickness t and the back surface width L ₁ , and the present invention has been achieved.

For this reason, in the ceramics-type projecting corner member of the present invention, two ceramics-type exterior plates having a thickness tmm having end surfaces inclined at an angle of 45 ° with respect to the design surface are bonded to each other at the inclined end surfaces. The back surface widths L ₁ mm and L ₂ mm of the _two ceramics-type exterior plates are in a relationship of L ₁ ≧ L ₂ and L ₁ / t ^1/2 is 43 mm ^1/2 or more. A ceramic industry projecting corner member in which a ceramic columnar member having a right-angle portion in a cross section is bonded to a right-angle corner portion on the inner surface thereof is bonded so that the right-angle portion is in contact with the ceramic industry. The system columnar member has an isosceles right triangle in cross section, and has a tmm-thick ceramic exterior plate 2 having an end surface inclined at an angle of 45 ° with respect to the design surface from one ceramic-type exterior plate having a thickness tmm. It is characterized by being cut out when producing a sheet .

  Here, examples of the ceramic columnar member include a right-angled triangle, an isosceles right-angled triangle, a rectangle including a square, and the like, but the cross-sectional shape is arbitrary as long as it has at least a right-angled part.

  In addition, the ceramic cornering member of the present invention is a ceramic columnar member having a right-angle portion in cross section, the cross section is an isosceles right triangle, and 45 mm from the ceramic surface plate having a thickness of tmm to the design surface. It is characterized by being cut out when two ceramics-type exterior plates having a thickness of tmm having end faces inclined at an angle of ° are produced.

  In such a ceramic columnar member, since the columnar end material cut out when producing two ceramic outer plates is a ceramic columnar member, industrial waste can be effectively used.

  ADVANTAGE OF THE INVENTION According to this invention, even if a back surface width | variety is large, the ceramic industry type | system | group protrusion corner member which does not need to pay special attention to handling in storage, packing, transportation, unpacking, construction, etc. can be provided.

  Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings, but the present invention is not limited thereto. FIG. 2 is a perspective view illustrating an example of a ceramics-type corner member according to the present invention, and FIG. 3 is a diagram illustrating an example of a method for manufacturing a ceramic-type corner member according to the present invention.

The ceramic industry projecting corner member 10 of the embodiment shown in FIG. 2 is, for example, a portion that requires a ceramic industry projecting corner member that covers from a projecting pillar to a stud in a building, or a normal part attached to the projecting pillar. It is used in places where the ceramics-type exterior plate is attached to the ceramics-type exterior plate so as to cover the end corner side end of the ceramic-type exterior plate.
This ceramics projecting corner member 10 forms two ceramics exterior plates 15 and 16 having inclined end surfaces 15B and 16B that are inclined at an angle of 45 ° with respect to the design surfaces 15A and 16A. It is manufactured in a substantially L shape by bonding the inclined end faces 15B, 16B of the ceramic-type exterior plates 15, 16, with the exterior plate design surface being the front side and the exterior plate rear surface being the inside. Ceramic based exterior plate 15, 16 thicknesses each tmm, equal height _{H 1,} and the rear surface 15C, 16C of the width (rear surface _{width) L} 1 _mm, L 2 mm is the relationship _{L 1} ≧ _{L 2,} L ₁ / t ^1/2 has become a 43mm ^1/2 or more. Typically, L ₁ ≧ 150 mm at t = 12 mm, L ₁ ≧ 170 mm at t = 15 mm, and L ₁ ≧ 190 mm at t = 18 mm.

The ceramics-type projecting corner member 10 has a ceramic-based columnar member 18 bonded to a right-angled corner portion 17 on the inner surface thereof.
The ceramic columnar member 18 has a right-angled isosceles triangular cross section, and is in surface contact with the back surfaces 15C and 16C of the ceramic exterior plates 15 and 16, and the right-angled portion is in contact with the right-angled corner portion 17. Are arranged as follows.

This ceramics columnar member 18 is formed such that the longitudinal dimension H ₂ is 10% to 100% with respect to the height H ₁ of the ceramics exterior plates 15 and 16. Incidentally, ceramic-based columnar member 18 is not limited to 1 real as shown in FIG. 1, may be adhered to the right-angled corner portion 17, for example, release the two columnar members in the vertical direction, H ₂ in this embodiment It is the sum of the dimension in the height direction of two columnar members.
As a specific example, 185 mm height _{H 1} of the ceramic based exterior plates 15 and 16, the longitudinal dimension of _{H 2} ceramic-based columnar member 18 was set to 100 mm.

The reason why H ₂ is preferably 10% to 100% with respect to H ₁ is as follows.
In other words, the longitudinal dimension of H ₂ ceramic-based columnar members 18 and the height H ₁ of the ceramic based exterior plate 15 and 16 is less than 10%, ceramic-based external corner member ceramic-based columnar member 18 is too short The reinforcing effect of the ten bonded portions cannot be sufficiently obtained. Typically 30% or more.
On the other hand, the longitudinal dimension of _{H 2} ceramic-based columnar members 18 and the height _{H 1} of the ceramic based exterior plates 15 and 16 exceeds 100% ceramic-based columnar member 18 from ceramic based exterior plates 15 and 16 It protrudes, and the protruding part cannot obtain a reinforcing effect, and becomes an obstacle when the ceramic-type projecting corner member 10 is constructed.
The ceramic columnar member 18 has a center in the longitudinal direction arranged at the center 21 of the ceramics exterior plates 15 and 16.
The ceramic-based 2 length of sides _W 1 of the cross section perpendicular portion of the columnar member _{18, W 2 (W 1 ≦} W 2), is preferably _{W 1} ≧ t / 2. If W ₁ <t / 2, a sufficient reinforcing effect may not be obtained. Typically, W ₁ = W ₂ = t / 2 ^1/2 .

Next, the manufacturing method of the ceramic industry type | system | group protrusion corner member 10 is demonstrated based on FIG. 3 (A)-(C).
First, as shown in FIG. 3A, a ceramic-type exterior plate having a predetermined length is prepared as a material exterior plate 40 having a thickness t, and the material exterior plate 40 has desired L ₁ and L ₂ . It cut | disconnects by the inclined lines 41 and 42 shown with an imaginary line so that the ceramics-type exterior plates 15 and 16 may be obtained.
As a result, as shown in FIG. 3B, a columnar end material having an isosceles right triangle shape (the lengths of the two sides of the right angle portion are both t / 2 ^1/2 ) is cut out, and the design surface The ceramic-type exterior plates 15 and 16 having the inclined end faces 15B and 16B inclined at an angle of 45 ° with respect to 15A and 16A are obtained. The columnar end material generated at this time is used as a ceramic columnar member 18 whose section is an isosceles right triangle.

Subsequently, as shown in FIG. 3C, an adhesive is applied to the inclined end faces 15 </ b> B and 16 </ b> B of the ceramics-type exterior plates 15 and 16, and then abutted against each other to form an L-shaped member 20.
And the end material mentioned above is bonded and fixed along the right-angled corner part 17 of the L-shaped member 20 as the ceramics columnar member 18, and the ceramics system corner member 10 is manufactured.

According to the ceramics-type projecting corner member 10 as described above, the adhesive strength of the adhesive portion can be improved by a simple structure in which the ceramic-based columnar member 18 is bonded and fixed along the right-angled corner portion 17.
Furthermore, the end material generated when cutting the substantially center of the material exterior plate 40 so that a columnar end material having an isosceles right triangle shape is cut out to form the ceramic industry exterior plates 15, 16 is used as the ceramic industry columnar member 18. Since it uses, it is not necessary to produce the ceramic columnar member 18 separately, and industrial waste can be reduced.
It is also possible to separately manufacture the ceramic columnar member 18 without using the mill ends as the ceramic columnar member 18.

It is a figure explaining the destructive testing method of a ceramic industry system corner member. It is a perspective view which shows the ceramic industry system corner member which concerns on this invention. It is a figure explaining the manufacturing method of the ceramic industry system corner member.
