Description
본 발명은 콘크리트 시료 양생몰드에 관한 것으로, 더욱 상세하게는 하절기의 고온이나 동절기의 저온이 몰드의 내부로 전도되지 않게 하여 양호한 상태의 공시체를 얻을 수 있도록 한 것이다.The present invention relates to a concrete sample curing mold, and more particularly, to prevent the high temperature of the summer season or the low temperature of the winter season from being conducted to the inside of the mold to obtain a specimen in a good state.
주지하다시피, 건축물을 구축함에 있어 철구조물을 설치하고 그 외부에 콘크리트를 양생시킴이 보통이며, 건축물의 골격을 이루는 기둥은 건축물의 하중 등을 충분히 이겨낼 수 있는 압축강도 등을 지니고 있어야만 건축물의 안전도를 향상시킬 수 있다.As is well known, when constructing a building, it is common to install steel structures and to cure concrete on the outside, and the pillars that form the skeleton of the building must have compressive strength to withstand the load of the building. Can improve.
따라서, 건축물의 골격을 형성하기 위한 콘크리트는 KS F 2403, 2404 등에 규격이 정해져 있는 양생몰드를 이용하여 일정한 규격(10×20㎝, 15×30㎝ 등)의 원주형 공시체를 제조하여 그 압축강도를 시험하고 있는데, 일반적인 콘크리트 압축강도 시험용 양생몰드는 서로 대응되는 2개의 반원통체와, 이 반원통체의 하단에 조립되는 받침대로 이루어지며, 반원통체와 받침대를 유동되지 않게 조립할 수 있도록 각 반원통체의 외측으로 조임돌기를 각각 돌출 형성하고, 이 조임돌기를 채워줄 수 있도록 일측 조임돌기에는 힌지볼트를 회전가능하게 장착하며, 힌지볼트에는 각 조임돌기를 채워주는 나비너트를 구비하게 된다.Therefore, concrete for forming the skeleton of a building is manufactured using cylindrical curing molds whose standards are defined in KS F 2403, 2404, etc., and manufactured cylindrical specimens of a certain standard (10 × 20 cm, 15 × 30 cm, etc.) and their compressive strength. The general concrete compressive strength test curing mold consists of two semi-cylindrical bodies corresponding to each other, and a pedestal assembled at the bottom of the semi-cylindrical body, so that the semi-cylindrical body and the pedestal can be assembled without flow. Each of the fastening protrusions are formed to protrude outwardly, and the hinge bolts are rotatably mounted on one side of the fastening protrusions to fill the fastening protrusions, and the hinge bolts are provided with butterfly nuts for filling the respective fastening protrusions.
또한, 하절기에는 기온이 너무 높게 되므로 몰드내측으로 고온이 전도되어 공시체 제조용 콘크리트가 너무 빨리 경화됨으로써 크랙이 발생될 수 있으며, 동절기에는 기온이 너무 낮게 되므로 콘크리트가 결빙되어 양호한 상태의 공시체를 형성할 수 없으므로 열전도율을 낮추기 위해 뚜껑을 구비하는 것도 있다.In addition, since the temperature is too high in the summer season, the high temperature is conducted inside the mold, so that the concrete for the specimen manufacturing hardens too quickly, and cracks may occur. In the winter, the temperature is too low, so the concrete freezes to form a specimen in good condition. There is also a lid provided to lower the thermal conductivity.
그러나, 이러한 종래 기술에 따른 콘크리트 시료 양생몰드는 하절기 또는 동절기의 너무 높거나 낮은 외기가 몰드의 내측으로 전도되는 것을 막기 위해 뚜껑을 구비한다 하더라도 열의 전도는 뚜껑부위로 전도되는 것이 아니고 몰드의 본체를 통해 전도되는 것이므로 열전도율을 원하는 수준으로 낮출 수는 없었으며, 이러한이유로 하절기 또는 동절기에는 양호한 상태의 공시체를 형성하기 어려워 콘크리트의 압축강도 시험을 거의 하지 못하는 실정이다.However, although the concrete sample curing mold according to the prior art has a lid to prevent the excessively high or low outside air in the summer or winter season from being conducted to the inside of the mold, the conduction of heat is not conducted to the lid portion and the body of the mold is transferred. Since it was conducted through, it was not possible to lower the thermal conductivity to the desired level. For this reason, it is difficult to form a specimen in good condition in summer or winter, and thus the compressive strength test of the concrete is rarely performed.
또한, 각각의 반원통체를 체결하기 위한 조임돌기, 힌지볼트, 나비너트 등의 부재가 너무 많이 소요되어 제조원가가 증가되며, 이러한 점을 감안하여 각 반원통체의 일측은 힌지축으로 결합 고정되고 나머지 일측만 힌지볼트와 나비너트를 이용하여 체결할 수 있도록 한 발명이 등장하였으나, 이 역시 각 반원통체 일측의 힌지축으로 결합 고정된 부위가 몰드의 상하로 다수개 구비되는 것이므로 구조가 복잡하고 제조원가가 수반되었으며, 반원통체를 체결하고 콘크리트를 주입한 후 다지기를 할 때 그 압력에 의해 반원통체간 위치가 상하로 어긋나게 되어 공시체가 압축강도에 영향을 줄 정도로 변형되는 문제도 있었다.In addition, the manufacturing cost is increased because too many fastening protrusions, hinge bolts, and butterfly nuts for fastening each semi-cylindrical body, in consideration of this point, one side of each semi-cylindrical body is coupled to the hinge shaft and the other side Invention has been made so that only the hinge bolt and the butterfly nut can be fastened, but this is also provided with a plurality of fixed parts coupled to the hinge shaft of one side of each semi-cylindrical structure by the upper and lower parts of the mold. In addition, there was a problem that the specimen is deformed to affect the compressive strength because the pressure between the semicylinders is shifted up and down by the pressure when the semicylindrical body is fastened and the concrete is injected after compaction.
아울러, 공시체를 성형하기 위한 지지역할을 하는 밑판도 별도의 힌지볼트와 나비너트를 이용하여야 하였으므로 체결작업이 어려움은 물론 제조원가를 증가시키는 원인이 되었으며, 뚜껑 역시 체결을 보다 용이하게 하면서 그 위치를 안정적으로 고정시킬 수 있는 구조가 요구되었다.In addition, since the base plate to be used for forming the specimens had to use a separate hinge bolt and a butterfly nut, it was difficult to tighten the work and increased the manufacturing cost. There was a need for a structure that can be secured with
본 발명은 이러한 점을 감안하여 제안된 것으로, 각 반원통체, 뚜껑, 밑판의 내부에 단열재를 삽입하여 하절기 또는 동절기에 고온 또는 저온이 몰드의 내부로 전도되지 않도록 함으로써 양생이 원활하게 이루어지게 하여 양호한 공시체를 제조하는 콘크리트 시료 양생몰드를 제공하는 데 그 목적이 있다.The present invention has been proposed in view of such a point, and inserting an insulating material inside each semi-cylindrical body, a lid, and a bottom plate so that high temperature or low temperature is not conducted to the interior of the mold during the summer or winter, so that curing is smoothly performed. The purpose is to provide a concrete sample curing mold for producing a specimen.
다른 견지로는, 각 반원통체의 일측을 그 중간부에서 힌지결합하여 회동하게 함과 동시에 각 반원통체의 접촉부에 라운드진 돌기와 이와 대응되는 홈을 형성하여 콘크리트 다지기 작업을 할 때 각 반원통체간 위치가 상하로 어긋나지 않게 하여 공시체의 변형을 방지하는 데 그 목적이 있다.In another aspect, one semi-cylindrical body is hinged at its intermediate part to be rotated, and at the same time, the semi-cylindrical position is formed when compacting concrete by forming rounded protrusions and corresponding grooves at the contact portions of each semi-cylindrical body. The purpose is to prevent the deformation of specimens by preventing them from shifting up and down.
또 다른 견지로는, 뚜껑과 밑판이 삽입하여 돌려 끼우는 방식으로 체결되게 하여 체결작업을 용이하게 함과 동시에 그 삽입위치가 안정적으로 고정되게 하는 데 그 목적이 있다.In another aspect, the purpose of the cap and the bottom plate is to be fastened by inserting and screwing in order to facilitate the fastening operation and to ensure that the insertion position is stably fixed.

이하, 본 발명을 제시되는 실시예에 따라 구체화한다.Hereinafter, the present invention will be embodied according to the examples presented.
본 발명에 따른 콘크리트 시료 양생몰드는 도 1 및 도 2에 도시한 바와 같이, 서로 대응되는 2개의 반원통체(1)(2)와 이 반원통체(1)(2)의 상하부에 체결되는 뚜껑(3) 및 밑판(4)의 내부에는 단열재(5)가 각각 삽입되며, 각 반원통체(1)(2)의 접촉부 일측 중간부에서는 길이방향으로 길게 축받이(6)(7)가 각각 돌출되고 그 축받이(6)(7)에 힌지핀(8)이 삽입되어 회동하게 되고, 각 반원통체(1)(2)의 접촉부에는 상면이 라운드진 다수의 돌기(9)와 이와 대응되는 다수의 홈(10)이 선택적으로 형성된다.As shown in FIGS. 1 and 2, the concrete sample curing mold according to the present invention includes two semicylindrical bodies 1 and 2 corresponding to each other and a lid fastened to upper and lower portions of the semicylindrical bodies 1 and 2. 3) and the heat insulating material 5 is respectively inserted in the inside of the base plate 4, and in the middle part of one side of the contact part of each semi-cylindrical body 1 and 2, the bearings 6 and 7 protrude in the longitudinal direction, respectively, The hinge pins 8 are inserted into the bearings 6 and 7 to rotate, and the contact portions of the semi-cylindrical bodies 1 and 2 have a plurality of protrusions 9 rounded on the upper surface and a plurality of grooves corresponding thereto. 10) is optionally formed.
이때, 뚜껑(3)과 밑판(4)은 도 3에 도시한 바와 같이 각 반원통체(1)(2)의 외측에 삽입하여 돌려 한번에 체결할 수 있도록 단면상 "??"형으로 구성하고 그 내경을 반원통체(1)(2)의 조립체 외경과 동일하게 구성하여 반원통체(1)(2)의 조립체외측으로 끼움되게 하되 뚜껑(3)과 밑판(4)의 내부에는 "ㄴ"형의 홈(11)을 대칭으로 형성하고, 각 반원통체(1)(2)의 외측으로는 "ㄴ"형 홈(11)에 대응되는 돌기(12)를 대칭으로 형성하게된다.At this time, the lid (3) and the bottom plate (4) is formed in a cross-section "??" type so that it can be tightened at once by inserting the outer side of each semi-cylindrical body (1) (2), as shown in Figure 3 and its inner diameter To the outside of the assembly of the semi-cylindrical body (1) (2) to be fitted to the outside of the assembly of the semi-cylindrical body (1) (2), but inside the lid (3) and the base plate 4 of the "b" type groove (11) are formed symmetrically, and the projections 12 corresponding to the "b" shaped grooves 11 are formed symmetrically on the outside of each semi-cylindrical body 1 and 2.
아울러, 도 4와 같이 단열효과를 높이기 위하여 각 반원통체(1)(2)는 그 접촉되는 부위에서 일측 반원통체를 연장하여 타측 반원통체의 외측을 감싸도록 구성하며, 그 연장부위까지 단열재(5)를 삽입하여 구성할 수도 있다.In addition, each semicylindrical body (1) (2) is configured to cover the outer side of the other semicylindrical body by extending one semicylindrical body at the contacted portion to enhance the thermal insulation effect as shown in FIG. You can also insert).
도면상의 미설명 부호 13, 14는 각 반원통체의 힌지 결합부 타측으로 돌출되는 브라켓이고, 15는 각 브라켓을 체결하기 위한 힌지볼트이다.Reference numerals 13 and 14 in the drawings are brackets protruding to the other side of the hinge coupling portion of each semi-cylindrical body, and 15 is a hinge bolt for fastening each bracket.
여기서, 각 반원통체(1)(2), 뚜껑(3), 밑판(4)의 내부에 단열재(5)를 삽입하는 것은 그 부재가 주철과 같은 철재일 경우에는 매우 어려우나, 최근에는 콘크리트 시료 양생몰드가 BMC(벌크 몰딩 컴파운드)나 ABS(안티몬 부타디엔 스틸렌)과 같은 합성수지재로 사출성형되고 있으므로 양생몰드의 사출시 각 반원통체(1)(2), 뚜껑(3), 밑판(4) 등의 부재를 중공상태로 성형하고 그 내부에 단열재(5)를 충진한 후 봉합하면 간단하게 형성할 수 있는 것이며, 이외에도 각 반원통체(1)(2), 뚜껑(3), 밑판(4)의 내부에 단열재(5)를 삽입할 수 있는 방법이면 무엇이든 가능하다.Here, it is very difficult to insert the heat insulating material 5 into each of the semi-cylindrical bodies 1, 2, the lid 3, and the bottom plate 4 when the member is made of iron such as cast iron. Since the mold is injection molded with synthetic resin materials such as BMC (bulk molding compound) or ABS (antimony butadiene styrene), each semi-cylindrical body (1) (2), lid (3), base plate (4), etc. It can be easily formed by molding the member in a hollow state and filling the heat insulating material 5 therein and then sewing it. In addition, the interior of each semicylindrical body 1, 2, lid 3, and base 4 Any method can be used as long as the heat insulator 5 can be inserted into it.
이와 같이 구성된 본 발명에 따른 콘크리트 시료 양생몰드는 각 반원통체(1)(2)를 힌지 결합부를 중심으로 회전시켜 닫게 되면 각 반원통체(1)(2)의 접촉부에 구비된 다수의 돌기(9)와 홈(10)이 서로 맞물려 체결되고, 힌지결합부 타측에서 각 브라켓(13)(14)을 힌지볼트(15)로써 체결하여 각 반원통체(1)(2)를 결합하게 되며, 이러한 상태에서 밑판(4)을 각 반원통체(1)(2)의 조립체 하부로부터 삽입하게 되는데, 조립체의 하부 양측에는 외측으로 돌기(12)가 돌출 형성되어 있고 밑판(4)의 내면에는 이 돌기(12)와 대응되는 "ㄴ"형의 홈(11)이 형성되어 있으므로 밑판(4)을 그 돌기(12)와 홈(11) 위치에 맞추어 끼운 후 돌리게 되면 밑판(4)과 반원통체(1)(2)의 조립체를 용이하게 체결할 수 있으며, 밑판(4)을 반대반향으로 돌리지 않는 한 그 체결위치가 고정될 수 있는 것이다.When the concrete sample curing mold according to the present invention configured as described above is closed by rotating each semicylindrical body (1) (2) around the hinge coupling portion, a plurality of protrusions (9) provided at the contact portion of each semicylindrical body (1) (2). ) And the groove 10 is engaged with each other, and each bracket (13) and 14 on the other side of the hinge coupling portion by fastening the hinge bolts 15 to engage each semi-cylindrical body (1) (2), this state In the bottom plate 4 is inserted from the bottom of the assembly of each semi-cylindrical body (1) (2), the projections 12 are formed on both sides of the lower side of the assembly to the outside and the projections 12 on the inner surface of the base plate (12) (B) is formed to correspond to the bottom plate (4) and the semi-cylindrical body (1) ( The assembly of 2) can be easily fastened, and the fastening position can be fixed unless the bottom plate 4 is turned in the opposite direction.
이때, 각 반원통체(1)(2)간 접촉부, 밑판(4)과 반원통체(1)(2) 조립체의 접촉부는 콘크리트가 누설되지 않도록 기밀하게 구성되어야 하며, 밑판(4)의 내부 상면은 원주형의 공시체 밑면이 평평하게 형성될 수 있도록 평평하게 구성되어야 함은 자명하다.At this time, the contact portion between each semi-cylindrical body (1) (2), the contact portion of the base plate (4) and the semi-cylindrical body (1) (2) assembly should be configured to be airtight so that concrete does not leak, the inner upper surface of the base plate (4) Obviously, the columnar specimen should be flat so that it can be formed flat.
이후, 각 반원통체(1)(2)와 밑판(4)이 이루는 원주형의 공간부에 콘크리트를 타설하고 양생하게 되며, 이러한 단계에서 외부 기온이 각 반원통체(1)(2)와 밑판(4) 내부에 삽입되어 있는 단열재(5)에 의해 몰드 내측으로 전도되지 않으므로 콘크리트가 변형없이 양호하게 양생될 수 있어 콘크리트 압축강도 시험에 적합한 원주형의 공시체가 완성될 수 있는 것이다.Thereafter, concrete is poured and cured in the cylindrical space formed by each semicylindrical body (1) (2) and the base plate (4). 4) Since it is not conducted to the inside of the mold by the heat insulator 5 inserted therein, the concrete can be cured well without deformation, and thus a cylindrical specimen suitable for the test of concrete compressive strength can be completed.
그런데, 하절기 또는 동절기에는 외부 기온이 너무 높거나 낮게 되므로 몰드에 별도의 뚜껑을 체결하여 외부기온을 차단하게 되는데, 본 발명에 따른 콘크리트 시료 양생몰드에도 뚜껑(3)이 구비되어 있으며, 이 뚜껑(3) 역시 밑판(4)과 마판가지로 각 반원통체(1)(2)에 대칭으로 형성되어 있는 돌기(12)에 그 "ㄴ"자 홈(11)의 입구를 맞추어 삽입하고 돌리는 방식으로 용이하게 체결할 수 있음은 물론 그 체결위치를 고정할 수 있으며, 이러한 상태에서는 뚜껑(3), 각 반원통체(1)(2), 밑판(4) 내부에 삽입되어 있는 단열재(5)에 의해 외부기온이 완전 차단되어 하절기 또는 동절기의 외부기온에 상관없이 콘크리트 압축강도 시험에 적합한 공시체를 제조할 수 있는 것이다.By the way, in the summer or winter season, the external temperature is too high or too low, so the external temperature is blocked by fastening a separate lid to the mold, the concrete sample curing mold according to the present invention is provided with a lid (3), this lid ( 3) It is also easy to insert and turn in accordance with the inlet of the "b" shaped groove 11 to the projection 12 formed symmetrically on each semi-cylindrical body (1) (2) with the base plate (4) and marlin branches. In addition, the fastening position can be fixed, and in this state, the lid 3, each semi-cylindrical body 1, 2, and the bottom plate 4 are externally insulated by the heat insulating material 5 inserted therein. It is possible to produce specimens suitable for testing the compressive strength of concrete regardless of the temperature outside in summer or winter due to the complete block of temperature.
한편, 콘크리트를 일정정도 채우고 다지기 작업을 할 때 각 반원통체(1)(2)가 그 접촉부에서 돌기-홈 방식으로 체결되어 있으므로 각 반원통체(1)(2)가 상하방향으로 어긋남이 없어 원주형 공시체의 변형을 미연에 방지할 수 있으며, 도 4와 같이 각 반원통체(1)(2)의 접촉부위에서 일측 반원통체를 연장하여 타측 반원통체의 외측을 감싸도록 구성하고 그 연장부위까지 단열재(5)를 삽입하게 되면 이 부위에서 단열재(5)가 겹쳐지게 되므로 단열재가 없는 빈 공간이 거의 없어 단열효과를 더욱 크게 할 수 있는 것이다.On the other hand, when semi-cylindrical bodies (1) and (2) are fastened in a protrusion-groove manner at their contact portions when filling and compacting concrete to a certain extent, the semi-cylindrical bodies (1) and (2) do not deviate in the vertical direction, and thus the circumference Deformation of the mold specimen can be prevented in advance, and as shown in FIG. 4, one semicylindrical body is extended from the contact portion of each semicylindrical body 1 and 2 to surround the outer side of the other semicylindrical body, and the insulation material is extended to the extended portion thereof. 5) If you insert the heat insulating material (5) is overlapped in this area, there is almost no empty space without the heat insulating material will be able to increase the heat insulation effect more.
이상에서 설명한 바와 같이, 본 발명은 뚜껑, 각 반원통체, 밑판의 내부에 단열재가 삽입되어 있는 것이므로 외부기온이 차단되어 양호한 양생효과를 도모할 수 있으며, 각 반원통체의 일측이 중간부에서 힌지결합되어 있으므로 체결작업이 편리하고 부품수 감소로 제조원가를 절감할 수 있으며, 각 반원통체의 접촉부가 돌기-홈 결합방식으로 체결되므로 콘크리트를 채우고 다지기 작업을 할 때 각 반원통체가 상하방향으로 어긋나지 않게 되어 공시체의 변형을 예방할 수 있고, 뚜껑 및 밑판을 각 반원통체에 밀어 끼워 돌리는 방식으로 체결하게 되므로 체결의 용이성을 도모할 수 있음은 물론 그 체결위치를 고정할 수 있어 콘크리트 압축강도 시험에 최적인 원주형의 공시체를 제작할 수 있는 이점이 있는 것이다.As described above, the present invention is a heat insulating material is inserted into the inside of the lid, each semi-cylindrical, the bottom plate can block the external air temperature can achieve a good curing effect, one side of each semi-cylindrical hinged at the middle Since the fastening work is convenient and the manufacturing cost can be reduced by reducing the number of parts, the contact part of each semi-cylindr is fastened by the protrusion-groove coupling method, so that each semi-cylindr does not shift in the vertical direction when filling and compacting concrete. It is possible to prevent deformation of specimens and to fasten the lid and bottom plate by pushing them into each semi-cylindrical body, thus facilitating fastening and fixing the fastening positions. There is an advantage that can produce a specimen of the mold.
