以下では、本考案の実施例における添付図面と組み合わせ、本考案の実施例における技術案を明確且つ完全に説明する。説明される実施例は本考案の全ての実施例ではなく、本考案の一部の実施例に過ぎないことは、明らかである。本考案における実施例に基づいて、当業者が創造的な労働を行わないことを前提に得られた全ての他の実施例は、本考案の保護する範囲に属す。 The following, combined with the accompanying drawings in the embodiments of the present invention, will clearly and completely explain the technical solutions in the embodiments of the present invention. It is clear that the described embodiments are not all embodiments of the present invention, but only some embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without any creative efforts fall within the protection scope of the present invention.
本考案は、図１～３に示すような、支持管１と、支持管１の外壁の両端に嵌接された接続管２とを含む簡易取り外し可能なケーシング管埋込固定装置を提供する。そのうちの一方の接続管２の底端に底部板４が固定的に接続され、底部板４の上端両側にケーシング管の位置を固定する内部支持構造が設けられ、内部支持構造は内部支持リング５を含み、内部支持リング５の一方側には内部支持リング５の水平方向位置を調節する調節部材が設けられ、接続管２の外壁には接続管２内における支持管１の位置を固定する固定構造が設けられている。 The present invention provides a simple and removable casing tube embedding and fixing device that includes a support tube 1 and connecting tubes 2 fitted to both ends of the outer wall of the support tube 1, as shown in FIGS. 1 to 3. A bottom plate 4 is fixedly connected to the bottom end of one of the connecting pipes 2, and an internal support structure is provided on both sides of the top end of the bottom plate 4 to fix the position of the casing pipe, and the internal support structure is connected to an internal support ring 5. An adjusting member is provided on one side of the internal support ring 5 to adjust the horizontal position of the internal support ring 5, and a fixing member is provided on the outer wall of the connecting pipe 2 to fix the position of the supporting pipe 1 within the connecting pipe 2. A structure is provided.
調節部材はねじ棒６を含み、ねじ棒６の外壁の一方側にはねじ棒６を回転させる回転レバー８が貫通して接続されている。 The adjustment member includes a threaded rod 6, and a rotating lever 8 for rotating the threaded rod 6 is connected to one side of the outer wall of the threaded rod 6 through the screw rod.
なお、内部支持構造内の回転レバー８を回すことでねじ棒６を同期して回転させて、内部支持リング５を押して水平方向の変位を実現し、ケーシング管が支持管１と接続管２の外壁に嵌設されたとき、ケーシング管の位置を効果的に固定して、コンクリートの打設時にケーシング管が固定装置上で揺れて、型枠内でのケーシング管の位置がずれて、その後の工事に支障を来すことを回避することができる。 In addition, by turning the rotary lever 8 in the internal support structure, the threaded rod 6 is rotated synchronously, pushing the internal support ring 5 and realizing horizontal displacement, so that the casing pipe is connected to the support pipe 1 and the connecting pipe 2. When fitted into the external wall, it effectively fixes the position of the casing pipe, preventing the casing pipe from swinging on the fixing device during concrete pouring, causing the position of the casing pipe within the formwork to shift, and subsequent It is possible to avoid any hindrance to the construction work.
底部板４の上端に固定ブロック７が固定的に接続され、固定ブロック７の一方側の中央部にねじ孔７０１が開けられ、ねじ孔７０１の内壁とねじ棒６の外壁とが回転可能に貫通して接続されている。 A fixed block 7 is fixedly connected to the upper end of the bottom plate 4, and a screw hole 701 is opened in the center of one side of the fixed block 7, and the inner wall of the screw hole 701 and the outer wall of the threaded rod 6 are rotatably penetrated. and is connected.
固定ブロック７に開けられたねじ孔７０１により、ねじ棒６が回動する際に水平方向の変位を実現することができる。なお、固定ブロック７の高さと内部支持リング５の高さとが等しい。 The screw hole 701 drilled in the fixed block 7 makes it possible to achieve horizontal displacement when the screw rod 6 rotates. Note that the height of the fixed block 7 and the height of the internal support ring 5 are equal.
内部支持リング５の一方側の中央部に位置決め溝５０１が開けられ、ねじ棒６の他方側には接続ブロック６０１が固定的に接続され、接続ブロック６０１の外壁の一方側に位置決めリング６０２が嵌設され、位置決め溝５０１の内壁が接続ブロック６０１の外壁と位置決めリング６０２の外壁にそれぞれ回転可能に貫通して接続されている。 A positioning groove 501 is formed in the center of one side of the internal support ring 5, a connecting block 601 is fixedly connected to the other side of the threaded rod 6, and a positioning ring 602 is fitted on one side of the outer wall of the connecting block 601. The inner wall of the positioning groove 501 is rotatably penetrated and connected to the outer wall of the connecting block 601 and the outer wall of the positioning ring 602, respectively.
実際の使用時に、接続ブロック６０１と位置決めリング６０２との内部支持リング５に開けられた位置決め溝５０１内での回転により、内部支持リング５がねじ棒６の回転に同期して回転することがなく、また、固定ブロック７の高さと内部支持リング５の高さとが等しいため、ねじ棒６の回動時に内部支持リング５が底部板４に拘束されて同期して回転することがなく、内部支持リング５の安定した支持が実現される。 During actual use, the rotation of the connection block 601 and positioning ring 602 within the positioning groove 501 formed in the internal support ring 5 prevents the internal support ring 5 from rotating in synchronization with the rotation of the threaded rod 6. In addition, since the height of the fixed block 7 and the height of the internal support ring 5 are equal, the internal support ring 5 is restrained by the bottom plate 4 and does not rotate synchronously when the threaded rod 6 rotates, and the internal support ring 5 is not rotated synchronously. Stable support of the ring 5 is realized.
接続管２の外壁の一方側にナット９が貫通して接続され、ねじ１０が貫通してナット９の内壁のねじ山に接続されている。 A nut 9 is passed through and connected to one side of the outer wall of the connecting pipe 2, and a screw 10 is passed through and connected to a thread on the inner wall of the nut 9.
ねじ１０を回してナット９内におけるねじ１０の位置を調節し、接続管２内にある支持管１に圧力を加えて、接続管２内における支持管１の位置を固定することにより、固定装置は、長さの異なるケーシング管の埋込のニーズに対応することができるようになり、使用範囲が拡大される。 By turning the screw 10 to adjust the position of the screw 10 in the nut 9 and applying pressure to the support tube 1 in the connection tube 2 to fix the position of the support tube 1 in the connection tube 2, the fixing device is installed. can now meet the needs of embedding casing tubes of different lengths, expanding the range of use.
他方の接続管２の上端に頂部板３が固定的に接続され１１、頂部板３の上端の中央部と底部板４の底端の中央部とのいずれにも孔１１が開けられ、孔１１の底端と接続管２の上端とが互いに貫通している。 A top plate 3 is fixedly connected to the upper end of the other connecting pipe 2 , and a hole 11 is formed in both the center of the upper end of the top plate 3 and the center of the bottom end of the bottom plate 4 . The bottom end of the connecting pipe 2 and the top end of the connecting pipe 2 penetrate through each other.
実際の使用では、支持管１は外径２６ｍｍの溶融亜鉛メッキＳＣ管又はＪＤＧ管を採用して、工事中の余剰材料を利用して加工してもよく、工事材料の利用率を高めると同時に、使用する必要になったら作ることで、実際の工事の操作を容易にする。また、頂部板３と底部板４とに使用される円形シートの直径は埋設ケーシング管の１．１倍で、頂部板３と底部板４とのいずれの中央部でも２６ｍｍの中空円環を切り取って、内径２６ｍｍｍの接続管と固定的に接続して、頂部板３と底部板４の厚さを８～１２ｍｍとすることで、実際の打設時に、コンクリートが埋設ケーシング管の内部に入るのを効果的に防止することができ、後のケーシング管内部のコンクリートの掃除を回避して、作業者の工事ステップを省く。 In actual use, the support pipe 1 may be a hot-dip galvanized SC pipe or JDG pipe with an outer diameter of 26 mm, which can be processed using surplus materials during construction, and at the same time improve the utilization rate of construction materials. By making it when it is necessary to use it, it facilitates the operation of the actual construction. In addition, the diameter of the circular sheet used for the top plate 3 and the bottom plate 4 is 1.1 times that of the buried casing pipe, and a 26 mm hollow ring is cut out in the center of both the top plate 3 and the bottom plate 4. By fixedly connecting the connecting pipe with an inner diameter of 26 mm and making the thickness of the top plate 3 and bottom plate 4 8 to 12 mm, it is possible to prevent concrete from entering the inside of the buried casing pipe during actual pouring. This can effectively prevent the cleaning of the concrete inside the casing pipe afterward, and save the worker's construction steps.
また、接続管２と頂部板３及び底部板４との接続方式としては、溶接による接続を採用することで、構造全体の安定性を保証する。また、壁体コンクリートの打設完了後、ケーシング管とコンクリートとが効果的に結合し、アルミ合金型枠の解体時、固定装置はケーシング管の内部から取り外し、上の階の構造の工事に回すことができるため、固定装置の利用率を高め、これにより型枠による打設時にアルミ合金型枠に埋込ケーシング管を配置するための空洞を開ける必要がなく、型枠全体の完全性を保証し、アルミ合金型枠の循環利用を容易にすると同時に、大きな空洞がアルミ合金型枠の構造安定性に影響を及ぼすことを回避する。 Further, as a method of connecting the connecting pipe 2 to the top plate 3 and the bottom plate 4, welding is used to ensure the stability of the entire structure. In addition, after the wall concrete is poured, the casing pipe and concrete are effectively bonded, and when the aluminum alloy formwork is dismantled, the fixing device can be removed from the inside of the casing pipe and used for construction of the structure on the upper floor. This increases the utilization of the fixing device, which eliminates the need to open a cavity for placing the embedded casing tube in the aluminum alloy formwork during formwork casting, ensuring the integrity of the entire formwork. This facilitates the recycling of aluminum alloy formwork, and at the same time avoids large cavities from affecting the structural stability of aluminum alloy formwork.
