Description

本発明は、PCトラス壁体構造物及びその施工方法に関するものであり、より詳細には、お互いに見合わせながら起立されて中央部には現場コンクリートが打設されるように、空間部が形成されるように組立される引張用PCパネルと圧縮用PCパネルをトラス連結材で相互連結することで、一体に挙動されて一式で運搬及び移動されて設置されるようにすることで、施工過程中には安全事故の憂慮がないように安全性が大きく強化されて一式で設置されるため施工が簡単でありながらも施工品質を大きく向上させることができるようにする安全性が強化されたPCトラス壁体構造物及びこれを利用した地下構造物施工方法に関するものである。すなわち、本発明はお互いに見合わせながら起立されて中央部には現場コンクリートが打設されるように空間部が形成されるように組立される引張用PCパネルと圧縮用PCパネルをトラス連結材で相互連結することで、一体で挙動されて運搬時、起立時、上部部材据え置き時、壁体とスラブ同時打設時の外力、そして風荷重と衝撃荷重に充分に耐えることができるし、延いては、本発明によるPC壁体と基礎間は下部鉄物で連結されるため設置時に別途の仮設材が必要ではないという長所を有した安全性が強化されたPCトラス壁体構造物及びこれを利用した地下構造物施工方法に関するものである。   The present invention relates to a PC truss wall structure and a construction method thereof, and more specifically, a space portion is formed so that on-site concrete is placed in the center portion while standing up together with each other. During the construction process, the tensile PC panel and the compression PC panel that are assembled in such a way are interconnected with a truss connection material so that they are moved together and transported and moved as a set. The PC truss with enhanced safety so that the construction quality is greatly improved while it is easy to install because the safety is greatly enhanced so that there is no concern about safety accidents. The present invention relates to a wall structure and an underground structure construction method using the same. That is, according to the present invention, a tensile PC panel and a compression PC panel, which are erected while matching each other and are assembled so that a space portion is formed so that on-site concrete is placed in the center portion, are made of truss connecting materials. By interconnecting, it can be fully integrated and can withstand external forces when transporting, standing up, placing the upper member, wall and slab at the same time, wind load and impact load, and extending The PC trough wall structure according to the present invention, which has the advantage that a separate temporary material is not required at the time of installation because the PC wall body and the foundation are connected by a lower iron object, and a PC truss wall structure having enhanced safety and the same. It relates to the construction method of underground structures used.

一般に廃水処理場、地下駐車場、雨水貯留槽のように地階に埋立てされる大容量及び大空間でなされる各種地下構造物は通常的に堀型基礎を形成し、その上に型枠を利用してRC工法によって現場コンクリートで外壁を施工した後、その外壁上端部に再びPCスラブまたは現場打設コンクリートスラブを安着させて施工する。
しかし、このようなRC工法による壁体構造物の施工方法は、壁体を形成するために必須に型枠を設置し、その型枠の中にコンクリートを現場で打設して硬化させた以後だけに後続工程を進行することができるため、工事期間の引き延びになる問題点があったし、ひいては型枠をいちいち設置してからとり除かなければならない煩わしさがあるだけではなく、コンクリートを現場で打設する過程で型枠が裂けるようになって安全事故が頻繁に発生する問題点があった。
Generally, various underground structures made up of large capacity and large spaces such as wastewater treatment plants, underground parking lots, and rainwater storage tanks that are buried in the basement usually form a moat-shaped foundation, and formwork is placed on top of it. After constructing the outer wall with concrete on site using the RC method, the PC slab or the concrete cast on the site is again attached to the upper end of the outer wall.
However, the construction method of the wall structure by such RC method is to install the formwork indispensable to form the wall, and after placing the concrete in the formwork and hardening it in the field Since the subsequent process can only proceed, there was a problem that the construction period was prolonged, and as a result, there was not only the troublesomeness that had to be removed after installing the formwork one by one, but also concrete There was a problem that safety accidents frequently occurred because the formwork was torn in the process of placing the machine on site.

このような従来のRC工法による壁体構造物の問題点を解決するために、図1に示されたように、サンドイッチPC-ウォールを利用した壁体構造物を施工する方法が特許文献1に開示されている。
前記従来の工法は、基礎上部面に外壁起立用溝を形成した後、前記溝の上に複数のパネルである第1PCパネルと第2PCパネルをそれぞれ所定の間隔を置いて見合わせながら起立されるように組立てた後、前記見合わせる両パネルの間の空間部に現場コンクリートを打設してパネルと共に一体でPC壁体を形成するように施工されるようにする。
しかし、このような従来の工法は、第1PCパネルと第2PCパネルをそれぞれ別個のパネルらをそれぞれ別に工場で生産した後それぞれ現場に運搬されて設置された後中央空間部に現場コンクリートが打設されるため、各PCパネルらが個別的だけで挙動して一体の壁体として作用することができる合成効果を示すことができないという短所があり、ひいては狭くて長い起立用溝に長さ方向に長く形成された各PCパネルが臨時に立てられるため、施工過程で転倒(overturning)されて致命的な人命事故が発生する深刻な問題点を内包している。
In order to solve such a problem of the wall structure by the conventional RC method, Patent Document 1 discloses a method of constructing a wall structure using a sandwich PC-wall as shown in FIG. It is disclosed.
In the conventional construction method, after forming a groove for standing the outer wall on the upper surface of the foundation, the first PC panel and the second PC panel, which are a plurality of panels, are erected while keeping a predetermined interval on the groove. After assembling, on-site concrete is placed in the space between the panels to be matched so that the PC wall is integrally formed with the panels.
However, in this conventional method, the first PC panel and the second PC panel are produced separately in the factory and then transported and installed on the site. Therefore, there is a disadvantage in that each PC panel can not act as a single wall by acting individually, and cannot exhibit a combined effect, and in the longitudinal direction, the narrow and long standing groove in the longitudinal direction. Since each long-formed PC panel is temporarily set up, it has a serious problem that it causes a fatal human accident due to overturning during the construction process.

また、従来の工法は個別的に立てられる第1PCパネルと第2PCパネルが外方へお互いに離れることを防止するように必ず貫通ホールを形成した後フォームタイ(登録商標)を設置して連結するため、中央部に現場コンクリートを打設する過程でフォームタイ(登録商標)が破損される問題点があり、内側パネルに形成された貫通ホールから漏水が発生するという問題点が相変らず発生している。   In addition, in the conventional method, the first PC panel and the second PC panel, which are individually set up, are always formed with through-holes so as to prevent the first PC panel and the second PC panel from moving away from each other. For this reason, there is a problem that Foam Tie (registered trademark) is damaged in the process of placing concrete in the center, and the problem that water leaks from the through hole formed in the inner panel continues to occur. ing.

したがって、前記のような地下構造物の壁体を施工するにおいて、従来の技術が有している問題点を解決することができながらも、人命事故や財産被害の憂慮がないように施工時には安全性が強化されて、構造的に安定されながらも工事期間を著しく縮めさせることができるし、ひいては施工品質を大きく向上させることができる新しいPC壁体構造物に対する必要性が相変らず頭をもたげている。   Therefore, when constructing the wall of an underground structure as described above, it is possible to solve the problems of the conventional technology, but it is safe at the time of construction so that there is no concern about human life accidents or property damage. The need for a new PC wall structure that can remarkably shorten the construction period while being structurally stable and can greatly improve the construction quality, while keeping the structure stable. ing.

As a result, it can be transported and moved as a set, so that there is an advantage that safety is greatly enhanced without worrying about human accidents and property damage in the construction process.

また、本発明は引張用PCパネルと圧縮用PCパネルがトラス連結材として一体で挙動されて一式で移動及び設置されるため、組立及び設置過程が非常に簡単でありながらも施工品質を大きく向上させることができるという長所がある。
また、本発明は圧縮用PCパネルの上側自由端部に脱落防止用ハンチが追加的に形成されていてスラブ安着を安定的にできて、施工が簡便で工事期間も縮めさせることができるという長所がある。
In addition, the present invention greatly improves the construction quality while the assembly and installation process is very simple because the PC panel for tension and the PC panel for compression are moved together as a truss connecting material and moved and installed as a set. There is an advantage that can be made.
Further, according to the present invention, an anti-dropping haunch is additionally formed on the upper free end of the compression PC panel, so that the slab can be stably seated, the construction is simple, and the construction period can be shortened. There are advantages.

延いては、本発明はお互いに見合わせながら起立されて中央部には現場コンクリートが打設されるように空間部が形成されるように組立される引張用PCパネルと圧縮用PCパネルをトラス連結材として相互連結することで一体に挙動されるため、運搬時、起立時、上部部材据え置き時、壁体とスラブの同時打設時に発生する外力、風荷重、衝撃荷重に充分に耐えることができるという長所があり、PC壁体と基礎間には下部鉄物が連結されるため設置過程で別途の仮設材が必要ではなくても安全性が確保されるという長所がある。
また、本発明は引張用PCパネルと圧縮用PCパネルとの間にトラス連結材を使用することでPC耐力を増進させてスラブから壁体まで一度に打設が可能であるという長所がある。
In other words, in the present invention, a truss connection is made between a tension PC panel and a compression PC panel that are erected while matching each other and are assembled so that a space portion is formed in the center portion so that on-site concrete is placed. Because they are connected together as a material, they can be fully integrated and can withstand external forces, wind loads, and impact loads that are generated during transportation, standing up, upper member standing, and simultaneous placement of wall and slab. Since the lower iron is connected between the PC wall and the foundation, safety is ensured even if a separate temporary material is not required during the installation process.
In addition, the present invention has an advantage in that a truss connecting material is used between the pulling PC panel and the compressing PC panel, so that the PC yield strength can be increased and the slab to the wall can be driven at a time.

以下、添付された図面を参照して本発明の選好的な実施例による安全性が強化されたPCトラス壁体構造物及びこれを利用した地下構造物施工方法に対して詳しく見ることにする。
先ず、本発明による安全性が強化されたPCトラス壁体構造物はPC TRUSS WALL構造体として、略称してPTWと言う。一方、本発明の選好的な実施例では前記トラス構造をトラス連結材で説明しているが、その用語の辞書的意味で限定されるものではなく、等しい機能と目的を達成することができる範囲内で他の用語の使用を排除するものではない。
Hereinafter, a PC truss wall structure with enhanced safety according to a preferred embodiment of the present invention and an underground structure construction method using the same will be described in detail with reference to the accompanying drawings.
First, the PC truss wall structure with enhanced safety according to the present invention is abbreviated as PTW as a PC TRUSS WALL structure. On the other hand, in the preferred embodiment of the present invention, the truss structure is described by a truss connecting material, but the terminology is not limited in terms of the terminology, and can achieve the same function and purpose. Does not exclude the use of other terms.

先ず図2に示されたように、本発明による基礎コンクリート上で垂直方向に立てられて等しい長さで形成されて所定の厚さを有した直四角形板形状のプレキャストコンクリートパネルでなされて複数のパネルで形成されて長さ方向に並んで設置された引張用PCパネル10と圧縮用PCパネル20が所定の間隔を形成し、お互いに見合わせながら起立されて、中央部には空間部が形成されるように組立された後、前記空間部の中に現場コンクリート40を打設して一体で形成されるPC壁体構造物において、前記PC壁体構造物は前記複数の引張用PCパネル10と複数の圧縮用PCパネル20の空間部には一体で挙動されるように相互連結される中央連結材30が含まれるが、前記中央連結材30は前記引張用PCパネル10の内部に埋立てされる第1垂直レール31aと、前記圧縮用PCパネル20の内部に埋立てされる第2垂直レール31bと、前記第1垂直レール31aと前記第2垂直レール31bを水平方向に連結するように所定の上下間隔で設置される複数個の水平材32と、前記複数個の水平材32の間で傾いた方向に連結される複数個の傾斜材33を基本的構成要素とする。   First, as shown in FIG. 2, a plurality of precast concrete panels having a predetermined thickness, which are vertically formed on a foundation concrete according to the present invention and have a predetermined thickness, are formed. The PC panel for tension 10 and the PC panel for compression 20 which are formed of panels and are arranged side by side in the longitudinal direction form a predetermined interval and are erected while matching each other, and a space is formed in the center. In the PC wall structure that is formed integrally by placing the on-site concrete 40 in the space after being assembled, the PC wall structure includes the plurality of tensile PC panels 10. The space portions of the plurality of compression PC panels 20 include a central connecting member 30 that is interconnected so as to behave integrally. The central connecting member 30 is buried in the tensile PC panel 10.

A plurality of horizontal members 32 installed at predetermined vertical intervals and a plurality of inclined members 33 connected in a tilted direction between the plurality of horizontal members 32 are used as basic components.

一方、本発明の選好的な実施例では主要構成要素として引張用PCパネル10と圧縮用PCパネル20を圧縮部材と引張部材で説明しているが、本発明によるPC壁体の設置時に圧縮部材は完工後には引張部材に変わられて、設置時引張部材は完工後圧縮部材に変わるようになる。したがって、本発明の主要構成要素である圧縮部材と引張部材はその用語の辞書的意味で限定されるものではなく、等しい機能と目的を達成することができる範囲内で他の用語の使用を排除するものではない。   On the other hand, in the preferred embodiment of the present invention, the tensile PC panel 10 and the compression PC panel 20 are described as the main components by the compression member and the tension member, but the compression member is installed when the PC wall body according to the present invention is installed. Is changed to a tension member after completion, and the tension member at the time of installation is changed to a compression member after completion. Accordingly, the compression member and the tension member, which are the main components of the present invention, are not limited by the dictionary meaning of the terms, and the use of other terms is excluded as long as the same function and purpose can be achieved. Not what you want.

以下、本発明による前記構成要素に対して具体的に説明する。先ず、廃水処理場のような地下構造物の壁体構造物の中で外壁体を形成するように前記引張用PCパネル10は圧縮用PCパネル20より長さ方向にさらに高く形成されることが選好される。しかし、使用者の目的によって廃水処理場のような地下構造物の壁体構造物の中で内壁体を形成するように前記引張用PCパネル10と圧縮用PCパネル20が等しい高さで形成されることもできる。
前記引張用PCパネル10と圧縮用PCパネル20は、お互いに見合わせる形状で形成され、その内部面には壁体のせん断補強のためのトラスガードが追加的に設置され、PCトラス壁体構造物とPCパネルとの一体性をさらに堅固に形成するようになる。
Hereinafter, the components according to the present invention will be described in detail. First, the tensile PC panel 10 may be formed higher in the length direction than the compression PC panel 20 so as to form an outer wall body in a wall structure of an underground structure such as a wastewater treatment plant. To be preferred. However, the tensile PC panel 10 and the compression PC panel 20 are formed at the same height so as to form an inner wall body in a wall structure of an underground structure such as a wastewater treatment plant according to the purpose of the user. You can also.
The PC panel for tension 10 and the PC panel for compression 20 are formed so as to match each other, and a truss guard for shear reinforcement of the wall is additionally installed on the inner surface thereof. And the PC panel are more firmly formed.

本発明のトラス連結材30の構成要素の中で第1垂直レール31aは前記引張用PCパネル10の内部に埋立てされて設置され、第2垂直レール31bは前記第1垂直レール31aの対向された位置に設置されて圧縮用PCパネル20の内部に埋立てされて設置される。
一方、トラス連結材30の水平材32は前記引張用PCパネルと圧縮用PCパネルがお互いに一体で挙動されることができるように前記第1、2垂直レール31a、31bを水平方向に連結するが、所定の間隔で上下方向に複数個が設置される。また、トラス連結材30の傾斜材33は引張用PCパネル10と圧縮用PCパネル20に加えられる荷重を効果的に分散されるように複数個の水平材32の間で傾いた方向に複数個が連結される。一方、本発明によるトラス連結材は四角形状の鋼管またはL字形鋼管が使われることが選好されるが、等しい目的と機能を達成することができる範囲内で円形鋼管、Hビーム、鉄筋などの他の形状の部材を使用することを排除するものではない。
Among the components of the truss connecting member 30 of the present invention, the first vertical rail 31a is buried in the inside of the pulling PC panel 10, and the second vertical rail 31b is opposed to the first vertical rail 31a. It is installed in the position where it was buried in the PC panel 20 for compression.
Meanwhile, the horizontal member 32 of the truss connecting member 30 connects the first and second vertical rails 31a and 31b in the horizontal direction so that the pulling PC panel and the compressing PC panel can behave integrally with each other. However, a plurality are installed in the vertical direction at a predetermined interval. In addition, there are a plurality of inclined members 33 of the truss connecting member 30 in a direction inclined between the plurality of horizontal members 32 so that the load applied to the pulling PC panel 10 and the compressing PC panel 20 is effectively dispersed. Are concatenated. On the other hand, the truss connecting material according to the present invention is preferably a rectangular steel pipe or an L-shaped steel pipe. It is not excluded to use a member of the shape.

一方、図3及び図4に示されたように、前記引張用PCパネルと圧縮用PCパネルがお互いに一体に挙動され、一式に移動されて設置されることができるように前記第1垂直レール31aと第2垂直レール31bを水平方向に連結する複数個の水平材32が設置される。この時、前記複数個の水平材の上下間隔は前記引張用PCパネルと圧縮用PCパネルの全体長さにかけて等間隔で形成されることが選好される。
一方、前記水平材32は一般的に等間隔形成されるが、前記引張用PCパネル10と圧縮用PCパネル20の間の耐力を計算して設置され、等間隔で形成されることで限定するものではない。
一方、前記引張用PCパネル10と前記圧縮用PCパネル20の下部部分に設置される水平材32は上下間隔が異なる部分に比べてさらに狭い間隔で形成されて、また上部部分に設置される水平材32は上下間隔が異なる部分に比べてさらに狭い間隔で形成される。
すなわち、前記水平材32は前記引張用PCパネル10と前記圧縮用PCパネル20は高さ方向の中間部分を基準で上下対称になるように、上下部分に設置される水平材32は中央部分に設置される水平材32よりさらに狭い間隔にして設置される。
Meanwhile, as shown in FIGS. 3 and 4, the first vertical rail may be installed so that the pulling PC panel and the compressing PC panel can be moved together and installed. A plurality of horizontal members 32 that connect 31a and the second vertical rail 31b in the horizontal direction are installed. At this time, it is preferable that the vertical intervals of the plurality of horizontal members are formed at equal intervals over the entire length of the tensile PC panel and the compression PC panel.
On the other hand, the horizontal members 32 are generally formed at equal intervals. However, the horizontal members 32 are installed by calculating the proof stress between the tensile PC panel 10 and the compression PC panel 20, and are limited by being formed at equal intervals. It is not a thing.
On the other hand, the horizontal members 32 installed in the lower part of the pulling PC panel 10 and the compression PC panel 20 are formed at a narrower distance than the parts having different vertical intervals, and are also installed in the upper part. The material 32 is formed at a further narrower interval than the portions having different vertical intervals.
That is, the horizontal member 32 is installed in the upper and lower parts so that the tensile PC panel 10 and the compression PC panel 20 are vertically symmetrical with respect to the intermediate part in the height direction. It is installed at a narrower interval than the horizontal member 32 to be installed.

次に図5乃至図8は、PCトラス壁体構造物の部分断面を示した図面である。前記PCトラス壁体構造物を連続されて設置される時、各壁体構造物間の触れ合われる隙間、すなわち、お互いに並んでいるように配列される複数個のPCパネルの間の隙間が外部環境に露出されることを防止するために、9防水材のようなバックアップ材をコーキングして内部が腐食されることを防止するようになる。   Next, FIGS. 5 to 8 are partial cross-sectional views of the PC truss wall structure. When the PC truss wall structures are installed in series, gaps between the wall structures, that is, gaps between a plurality of PC panels arranged side by side are external. In order to prevent exposure to the environment, a backup material such as 9 waterproofing material is caulked to prevent the interior from being corroded.

次に図9は、前記PCトラス壁体構造物の上側部分及びトラス連結材30が結合された部分を拡大した図面である。前記壁体構造物を水平方向にお互いに連結される時継ぎ部位、すなわち、お互いに並んでいるように配列される複数個のPCパネルらをお互いに連結する区間及び補強が必要な区間に板-板補強筋Pが追加に形成されて、継ぎ長さの最小化のために小さな直径で形成されるワイヤメッシュで形成される。
また、トラス連結材30を拡大した図面に対して、前記水平材32と水平材32との間には運搬、揚重、起立時水平変位を最小化するために断面連結材34が追加で形成される。すなわち、前記各PCパネル10、20には複数個のトラス連結材が設置されて、前記一トラス連結材の水平材の一側端部と隣り合うトラス連結材の水平材の他側端部はPC壁体構造物の運搬、揚重及び起立時長さ方向の外力に対する水平変位を最小化することができるように断面連結材が追加で含まれる。この時、壁体下端に形成される鉄筋干渉部は起立後除去されるようになる。
Next, FIG. 9 is an enlarged view of the upper portion of the PC truss wall structure and the portion to which the truss connecting member 30 is coupled. The wall structure is connected to each other in a horizontal direction, that is, a section connecting a plurality of PC panels arranged side by side to each other and a section requiring reinforcement. A plate reinforcement bar P is additionally formed and formed of a wire mesh formed with a small diameter for minimizing the joint length.
Further, with respect to the drawing in which the truss connecting member 30 is enlarged, a cross-section connecting member 34 is additionally formed between the horizontal member 32 and the horizontal member 32 in order to minimize horizontal displacement during transportation, lifting and standing. Is done. That is, each of the PC panels 10 and 20 is provided with a plurality of truss connecting members, and the other side end of the horizontal member of the truss connecting member adjacent to the one side end of the horizontal member of the one truss connecting member is A cross-section connecting material is additionally included so that horizontal displacement with respect to external force in the longitudinal direction during transportation, lifting and standing of the PC wall structure can be minimized. At this time, the reinforcing bar interference portion formed at the lower end of the wall body is removed after standing.

一方、前記断面連結材34が連結される前記水平材32は使用目的によって傾斜材33に連結されることを排除するものではない。
また、前記水平材32と第1、2垂直レール31a、31bの間には板形状の第1、2連結材35a、35bが追加に形成されて、前記第1、2連結材35a、35bは水平材と垂直レールが連結される時に接合される面積を最大化するようになる。すなわち、前記水平材32または傾斜材33と前記第1、2垂直レール31a、31bが相互連結される時に接合される面積が最大化されるように、前記水平材32または傾斜材33と第1、2垂直レール31a、31bとの間には第1、2連結材35a、35bが追加的に設置されることもできる。
On the other hand, the horizontal member 32 to which the cross-section connecting member 34 is connected does not exclude being connected to the inclined member 33 depending on the purpose of use.
Further, plate-shaped first and second connecting members 35a and 35b are additionally formed between the horizontal member 32 and the first and second vertical rails 31a and 31b, and the first and second connecting members 35a and 35b are When the horizontal member and the vertical rail are connected, the area to be joined is maximized. That is, when the horizontal member 32 or the inclined member 33 and the first and second vertical rails 31 a and 31 b are interconnected, the horizontal member 32 or the inclined member 33 and the first member are maximized. First and second connecting members 35a and 35b may be additionally installed between the two vertical rails 31a and 31b.
