Description
【０００１】
【発明の属する技術分野】
本発明は橋脚、煙突等塔状構造物に適用される充填被覆形鋼管コンクリート塔状構造物に係るものである。
【０００２】
【従来の技術】
従来の橋脚の構造は直径３２ｍｍ、あるいは５１ｍｍの主筋を１５０ｍｍ間隔で、ダブル配筋した鉄筋コンクリート構造で主体を構成し、また直径１６〜２５ｍｍの帯鉄筋が１５０ｍｍ間隔で配筋されている。
一部、Ｈ鋼を鉄筋の断面に換算して鉄筋と組合せたＳＲＣ構造の橋脚がみられるが、この場合も帯筋が必要となる。
【０００３】
【発明が解決しようとする課題】
前記従来構造においては、太径の主筋が１５０ｍｍ間隔でダブルに配筋されるため、継手の施工に多くの時間を要し、また主筋の間隔が狭いとコンクリートの施工に多大の手間を要する。また帯筋が必要であり、この帯筋の組立に多くの時間を要する。
【０００４】
更に橋脚の施工において工程的に時間がかかり、特に鉄筋組立作業に工程的に多大の時間と手間を要す。
本発明は前記従来技術の有する問題点に鑑みて提案されたもので、その目的とするところは、鉄筋組立の省力化が図られ、工程が短縮化され、構造的には耐震性に優れた充填被覆形鋼管コンクリート塔状構造物を提供する点にある。
【０００５】
【課題を解決するための手段】
前記の目的を達成するため、本発明に係る充填被覆形鋼管コンクリート塔状構造物は、一周する側壁部により画成される中空の水平断面形状を有する充填被覆形鋼管コンクリート塔状構造物において、前記側壁部の壁内に列設するようにして基礎部に建込まれ、且つ高強度、高流動コンクリートが充填された鉛直方向に延在する複数の鋼管と、横方向に相隣る前記鋼管に亘って挿入され、それら鋼管内の高強度、高流動コンクリートで強固に拘束されることによってそれら鋼管どうしを接続する異形鉄筋とで構成された、前記側壁部の壁内を一周する補強骨組構造体を備え、該補強骨組構造体が鉄筋コンクリート構造で被覆されることで、前記側壁部が構成されていることを特徴とする。
【０００６】
【発明の実施の形態】
図面は本発明の好ましい実施の形態を示すもので、この実施の形態に係る充填被覆形鋼管コンクリート塔状構造物は、図１に示すように、一周する側壁部により画成される中空の水平断面形状を有する塔状構造物である。基礎部より所要位置毎に鋼管１を建て込んであり、それら複数の鋼管１は、図１に示すように側壁部の壁内に列設するようにして建込 まれており、また、図２に示すように鉛直方向に延在している。各鋼管１には、高強度、高流動コンクリート２を充填する。横方向に相隣る鋼管１どうしの横方向の繋ぎは、異形鉄筋３を前記コンクリートが充填されるそれら鋼管１に挿入することにより、その異形鉄筋３がそれら鋼管１内の高強度、高流動コンクリート２により拘束されることによって、それら鋼管１が横方向に継接される。これによって、図１に示すように、充填被覆形コンクリート塔状構造物の側壁部の壁内を一周する補強骨組構造体が構成される。尚、図３は鋼管１の異形鉄筋３による隅角部分の接合部を示し、図４は鋼管１の異形鉄筋３による一般部分の接合部を示す。
【０００７】
次いで前記鋼管１群の周囲に鉄筋４を配筋したのち、前記異形鉄筋３で継接された鋼管１群及び鉄筋４を囲繞する型枠６を組み立て被覆コンクリート５を打設する。これによって、鋼管１と異形鉄筋３とで構成された補強骨組構造体が鉄筋コンクリート構造で被覆されて、充填被覆形鋼管コンクリート塔状構造物の側壁部が構成される。
【０００８】
【発明の効果】
本発明に係る充填被覆形鋼管コンクリート塔状構造物は前記したように、基礎部に建て込まれた鋼管に高強度、高流動コンクリートが充填され、同各鋼管の横繋ぎは異形鉄筋を横方向に相隣る鋼管内に挿入して、同鋼管内の高強度、高流動コンクリートで強固に拘束することによって行われるので、溶接が全く不要となり、施工性が著しく向上される。
【０００９】
また前記鋼管は高強度、高流動コンクリートが充填されているので、終局耐力と靱性が確保され、鉄筋に代わる機能を発揮し、工程的に手間のかかる鉄筋の配筋作業が省力化される。更に前記したように異形鉄筋を介して接合された、高強度、高流動コンクリート充填型鋼管が鉄筋コンクリート構造で被覆されていることによって水平剛性が確保され、振動特性が改善され、地震時の安全性が確保される。また前記コンクリート充填鋼管群によって鉄筋量が低減され、配筋、作業等の省力化が図られる。

BACKGROUND OF THE INVENTION
The present invention relates to a packed-clad steel pipe concrete tower-like structure applied to tower-like structures such as piers and chimneys.
[0002]
[Prior art]
The structure of a conventional pier is mainly composed of a reinforced concrete structure in which main bars having a diameter of 32 mm or 51 mm are doubled at intervals of 150 mm, and reinforcing bars having a diameter of 16 to 25 mm are arranged at intervals of 150 mm.
In some cases, bridge piers with an SRC structure in which H steel is converted into a cross section of a reinforcing bar and combined with the reinforcing bar are seen, but in this case also a band is required.
[0003]
[Problems to be solved by the invention]
In the conventional structure, since the main reinforcing bar with a large diameter is doubled at intervals of 150 mm, it takes a lot of time to install the joint, and if the interval between the main bars is narrow, it takes a lot of work to install the concrete. In addition, a strap is required, and it takes a lot of time to assemble the strap.
[0004]
Furthermore, it takes time in the process of construction of the pier, and in particular, a great deal of time and labor is required in the process of assembling the reinforcing bars.
The present invention has been proposed in view of the above-mentioned problems of the prior art. The purpose of the present invention is to save labor in rebar assembly, shorten the process, and have excellent earthquake resistance structurally. The object is to provide a packed-coated steel tube concrete tower structure.
[0005]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the filled-coated steel pipe concrete tower structure according to the present invention is a filled-coated steel pipe concrete tower structure having a hollow horizontal cross-sectional shape defined by a side wall portion that goes around. is written denominated in foundation so as to arrayed in a wall of said side wall portions, and high strength, and a plurality of steel pipe high flow concrete extends vertically filled, the steel pipe in the transverse direction phase Tonariru are inserted over the high strength in those steel pipes were constructed by the deformed bar which connects to what they steel pipe by being firmly bound with high fluidity concrete, reinforced scaffold to go around the inside wall of the side wall portions A side wall portion is formed by providing a structure and covering the reinforcing frame structure with a reinforced concrete structure.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The drawings show a preferred embodiment of the present invention . As shown in FIG. 1, the filled-clad steel pipe concrete tower-like structure according to this embodiment is a hollow horizontal defined by a side wall portion. It is a tower-like structure having a cross-sectional shape. There Nde write built steel pipe 1 for each predetermined position from the base portion, the plurality of steel tube 1 is directed Kenkomi Marete so as to arrayed in the wall of the sidewall portion as shown in FIG. 1, FIG. 2 As shown in FIG. Each steel pipe 1 is filled with high strength,
[0007]
Next, after reinforcing
[0008]
【The invention's effect】
As described above, the filled coated steel pipe concrete tower structure according to the present invention is filled with high-strength, high-fluidity concrete in the steel pipe built in the foundation part, and the horizontal joint of each steel pipe is in the transverse direction of the deformed reinforcing bar. Since it is inserted into the steel pipes adjacent to each other and firmly restrained by the high-strength, high-fluidity concrete in the steel pipes, welding is not required at all and the workability is remarkably improved.
[0009]
Further, since the steel pipe is filled with high strength and high fluidity concrete, the ultimate strength and toughness are ensured, the function to replace the reinforcing bar is exhibited, and the reinforcing work of the reinforcing bar which is troublesome in the process is saved. Furthermore, as mentioned above, the high-strength, high-fluidity concrete-filled steel pipes joined via deformed reinforcing bars are covered with a reinforced concrete structure, ensuring horizontal rigidity, improving vibration characteristics, and safety during earthquakes. Is secured. Further, the amount of reinforcing bars is reduced by the concrete-filled steel pipe group, and labor saving such as reinforcement and work is achieved.
