본 발명은 건축물의 외벽 등으로 설치되는 안전 접합유리내에 볼트를 인서트 조립 구성하여 외부에서 볼트 조립작업이나 조립구멍 형성이 배제되어 조립작업성 향상은 물론 외관의 미려함, 누수방지 등을 제공하는 건물 외벽용 안전 접합유리의 제조방법과 그에 의해 제조된 안전 접합유리에 관한 것이다.The present invention eliminates the bolt assembly work or the formation of assembly holes from the outside by inserting the bolt assembly in the safety laminated glass installed on the exterior wall of the building, thereby improving the assembly workability, as well as the beauty of the exterior, leakage prevention, etc. It relates to a method for producing safety laminated glass for safety and to a safety laminated glass produced thereby.

최근에 이르러 건물 외벽 등에 건물의 하중을 지지하지 않고 칸막이 형태로 설치되는 유리 벽면은 미관과 함께 채광이 우수하여 많이 적용하고 있는 추세이다.In recent years, glass walls, which are installed in the form of partitions without supporting the load of the building on the outer wall of the building, have been applied to many because of their excellent light and beautiful lighting.

이러한 유리 벽면은 건물 외벽에 세워진 지지보(2)상에 고정용 금구(3)를 "X"자 형으로 설치하고, 상기 고정용 금구(2)에 전후좌우로 유리판(5)을 연속 고정시켜 설치하도록 구성된다.The glass wall surface is provided with a fixing bracket (3) in the form of an "X" on the support beam (2) standing on the outer wall of the building, and the glass plate (5) continuously fixed to the fixing bracket (2) in front, rear, left and right. It is configured to install.

이때, 상기 유리판(5)과 고정용 금구(3)는 볼트(6)로 상호 체결고정하게 되는데, 볼트의 돌출을 방지하기 위해서 상기 볼트는 접시머리 볼트를 적용하고 유리판에는 접시머리 볼트에 대응되는 조립홈을 가공하여 조립 체결하게 된다.In this case, the glass plate 5 and the fixing bracket 3 are fastened to each other by bolts 6. In order to prevent protrusion of the bolts, the bolts are provided with countersunk head bolts, and the glass plates correspond to countersunk head bolts. The assembly groove is processed and assembled.

그러나, 상기한 유리 벽면의 구조는 외측으로 볼트가 노출되어 미관을 해침은 물론 상기 볼트의 조립용 구멍을 통해 빗물이나 이물질이 유입되어 오염되면서 갖가지 문제점을 유발하였다.However, the structure of the glass wall surface is exposed to the outside of the bolt to harm the aesthetics as well as the rainwater or foreign matter is introduced through the assembling holes of the bolt, causing various problems.

또한, 상기한 종래의 유리 벽면은 유리판(5)의 외측에서 볼트를 삽입하고 그 내측에서 너트로 고정용 금구(3)에 체결고정하면서 작업하기 때문에 유리판의 내,외측에서 작업을 병행해야하므로 작업이 매우 불편한 문제점이 있었다.In addition, since the conventional glass wall surface works while inserting a bolt from the outside of the glass plate 5 and fastening and fastening to the fixing bracket 3 with a nut from the inside thereof, work must be performed at the inside and outside of the glass plate in parallel. There was a very uncomfortable problem.

한편, 종래의 안전 접합유리는 상,하 유리판 사이로 가소화된 폴리비닐 부티랄(PVB)쉬트를 삽입시켜 가열 및 압압로울러에 압압 이송하면서 폴리비닐 부티랄(PVB)층에 의해 상,하 유리판을 접합한 안전 접합유리를 제조하였다.Meanwhile, the conventional safety laminated glass inserts a plasticized polyvinyl butyral (PVB) sheet between the upper and lower glass plates, and presses and transports the upper and lower glass plates by a polyvinyl butyral (PVB) layer while pressing and transporting them to a heating and pressing roller. The laminated safety laminated glass was produced.

그러나 상기한 종래의 안전 접합유리는 유리판 외부로 돌출되는 부재가 존재할 때 종래와 같이 압압로울러에 의해 이송하는 것이 곤란하여 그 제조한 곤란한 문제점이 있었다.However, the above-mentioned conventional safety laminated glass is difficult to transport by a pressure roller as in the prior art when there is a member that protrudes out of the glass plate, there was a difficult problem of manufacturing.

본 발명은 상기한 종래 기술이 갖는 제반 문제점을 해결하고자 창출된 것으로서, 건축물의 외벽 등으로 설치되는 유리 벽면내에 볼트를 인서트 조립하여 외관에서 볼트나 볼트의 조립 구멍이 형성되지 않아 미려함은 물론 누수 방지를 우수하게 제공하는데 그 목적이 있다.The present invention was created to solve all the problems of the prior art described above, by inserting the bolt into the glass wall that is installed in the outer wall of the building, etc., the assembly hole of the bolt or bolt is not formed in the exterior, as well as preventing leakage The purpose is to provide excellent.

본 발명은 유리 벽면내에 볼트가 인서트 조립되어 있기 때문에 건물의 외벽에 고정 설치하는 작업시 외측에서 볼트의 삽입을 위한 작업이 배제되어 조립 작업성이 매우 편리하게 제공되는데 그 목적이 있다.According to the present invention, since the bolt is inserted into the glass wall, the work for the insertion of the bolt from the outside during the fixed installation on the outer wall of the building is excluded, and thus the assembly workability is provided very conveniently.

이러한 본 발명의 목적은, The purpose of this invention,

볼트가 조립된 하부 유리판과 상부 유리판 사이로 폴리비닐 부틸알(PVB)쉬트및 기타 필름(EVA필름 등)을 예열 열처리한 후 삽입하여 고무패킹으로 밀폐한 후, 종래와 같은 압압로울러 대신에 가열로 내에서 공압열처리하므로 상,하 유리판을 접합하는 것에 의해 볼트가 인서트 조립된 안전 복합유리를 제공함에 의해 달성된다.Pre-heat-treated polyvinyl butylal (PVB) sheets and other films (such as EVA films) between the lower glass plate and the upper glass plate assembled with bolts, insert them, seal them with rubber packing, and replace them with a conventional pressure roller. Pneumatic heat treatment at is achieved by providing a safety composite glass, the bolt is insert-assembled by bonding the upper and lower glass plates.

먼저, 본 발명의 제조방법을 첨부도면 도 2를 참조하여 살펴보기로 한다.First, the manufacturing method of the present invention will be described with reference to the accompanying drawings.

본 발명의 건물 외벽용 안전 접합유리를 제조함에 있어,In manufacturing safety laminated glass for building exterior wall of the present invention,

기 가공된 볼트 조립홀(15)로 볼트(50)를 삽입하여 조립한 하부 유리판(10)과, 상부 유리판(20) 사이로 폴리비닐 부티랄(PVB)쉬트(30)를 삽입하여 예압오븐에서 60~80℃로 예열처리를 하여 적층하는 유리 적층공정과;Insert the polyvinyl butyral (PVB) sheet 30 between the lower glass plate 10 assembled by inserting the bolt 50 into the prefabricated bolt assembly hole 15 and the upper glass plate 20, A glass lamination step of laminating by preheating at ˜80 ° C .;

상기 적층된 상,하 유리판(10)(20)의 외곽과, 하부 유리판 저면의 볼트(50) 돌출부분을 내열 고무패킹(40)(40')으로 조립하여 밀폐되게 마감하는 패킹 마감공정과;A packing finishing process of assembling the outer periphery of the stacked upper and lower glass plates 10 and 20 and the bolt 50 protruding portion of the lower glass plate with heat-resistant rubber packings 40 and 40 'to seal and seal them;

상기 적층된 상,하 유리판(10)(20)을 가열로 내부에서 120~150℃로 공압열처리하여 상기 폴리비닐 부티랄(PVB)쉬트(30)가 용융되면서 상하 유리판을 접합하는 가열 접합공정 및 상온에서 냉각하는 냉각공정에 의해 볼트가 인서트된 안전 접합 유리를 제조하도록 이룬다.Pneumatic heat treatment of the laminated upper and lower glass plates 10 and 20 at 120 to 150 ° C. in a heating furnace to heat and bond the upper and lower glass plates while melting the polyvinyl butyral (PVB) sheet 30. It is made to manufacture a safety laminated glass with bolts inserted by a cooling process of cooling at room temperature.

이때, 상기 유리 적층공정에서 볼트를 접시머리 볼트로 사용함이 바람직하고, 조립홀에 조립시 볼트가 하부 유리판의 전면으로 돌출되지 않도록 조립함이 바람직하다.In this case, it is preferable to use the bolt as a countersunk head bolt in the glass lamination process, and it is preferable to assemble the bolt so that the bolt does not protrude toward the front of the lower glass plate when assembled in the assembling hole.

상기 패킹 마감공정에서 상하 유리판의 외곽과 하부 유리판의 볼트 돌출부분으로 내열 고무 패킹을 조립 마감하는 것은 가열로에서 가열시 상,하 유리판 사이가 고온 고압으로 가열되면서 내부 공기가 외부로 이동하여 내부 진공상태를 유지하면서 폴리비닐 부티랄(PVB)쉬트가 상,하 유리판에 효과적으로 밀착되어 접합 효율을 극대화함은 물론 가열과정에서 각종 이물질의 유입을 차단하기 위함이다.In the packing finishing process, assembling and finishing the heat-resistant rubber packing to the outer edge of the upper and lower glass plates and the bolt protrusions of the lower glass plates is performed by heating the upper and lower glass plates to a high temperature and high pressure during heating in a heating furnace, so that the internal air moves to the outside and the internal vacuum While maintaining the state, the polyvinyl butyral (PVB) sheet is effectively adhered to the upper and lower glass plates to maximize the bonding efficiency and to block the inflow of various foreign substances in the heating process.

상기 가열 접합공정에서 상,하 유리판을 120~150℃로 4~5시간을 가열함이 바람직한데, 상기 가열온도가 120℃ 미만일 경우에 폴리비닐 부티랄(PVB)쉬트의 용융 접합이 효과적으로 이루어지지 않게 되고, 상기 가열온도가 150℃ 초과일 경우에 쉬트 및 유리판의 물성이 변색되는 등의 문제점이 발생될 우려가 있기 때문이다.In the heat bonding process, it is preferable to heat the upper and lower glass plates at 120 to 150 ° C. for 4 to 5 hours. When the heating temperature is less than 120 ° C., the melt bonding of the polyvinyl butyral (PVB) sheet is not effectively performed. This is because there is a possibility that problems such as discoloration of the physical properties of the sheet and the glass plate occur when the heating temperature is higher than 150 ° C.

특히 상기 폴리비닐 부티랄(PVB)쉬트의 용융 접합 조건은 일반적인 안전 접합유리의 공정 조건을 준용하는 것으로 동일하게 제조하게 된다.In particular, the melt-bonding conditions of the polyvinyl butyral (PVB) sheet are produced in the same manner by applying the process conditions of general safety laminated glass mutatis mutandis.

상기 하부 유리판(10)과, 상부 유리판(20) 사이에는 폴리비닐 부티랄(PVB)쉬트(30)이 아닌 EVA필름 등의 기타 필름도 적용가능하다.Other films such as EVA films other than the polyvinyl butyral (PVB) sheet 30 may be applied between the lower glass plate 10 and the upper glass plate 20.

이러한 본 발명은 볼트를 삽입 조립한 하부 유리판과, 상부 유리판 사이로 폴리비닐 부티랄(PVB)쉬트를 삽입 적층하여 종래의 압압로울러에 의한 방식이 아닌 가열로 내부에서 가열하여 상,하 유리판을 접합하기 때문에 볼트가 돌출된 상태로서 안전 접합유리의 제조가 가능하게 되는 것이다.The present invention is laminated by inserting a polyvinyl butyral (PVB) sheet between the lower glass plate and the upper glass plate inserted into the assembly by heating in the heating furnace rather than the conventional pressure roller to join the upper and lower glass plates. Therefore, it is possible to manufacture the safety laminated glass as the bolt protrudes.

따라서, 건축물의 외벽 등으로 설치시 볼트 및 볼트 조립 구멍이 노출되지 않아 미려함은 물론 누수 방지를 우수하게 제공하고, 또한 별도의 볼트 조립작업이 배제되어 조립 작업성이 매우 편리하게 제공되는 잇점을 갖는 것이다.Therefore, the bolt and bolt assembly holes are not exposed when installed on the outer wall of the building, which provides beauty as well as excellent leakage prevention, and also eliminates additional bolt assembly work, thereby providing very convenient assembly workability. will be.
