分割ボツクスカルバートの型枠装置に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a formwork device for a two-part box culvert that can adjust the width of the formwork by a predetermined width.

あらたな別の専用型枠を組み立てるものであり、
極めて能率の悪いものである。また、僅かな型枠
の高さ変更においても同様である。 Traditionally, each piece of a two-part box culvert has been formed using its own mold. For example, this dedicated formwork is constructed by assembling each dedicated weir board into the shape of the culvert to be formed. Therefore, it is used exclusively for divided pieces of one predetermined size, and cannot be used for other pieces having different sizes. This method involves assembling a new dedicated formwork even if the width of the waterway is slightly changed.
This is extremely inefficient. The same applies to slight changes in the height of the formwork.
また、従来のものは分割ピースの型枠からの脱
型が煩雑であつた。これは、各堰板の解体手間な
どに起因するものである。 Furthermore, in the conventional method, it was complicated to remove the divided pieces from the mold. This is due to the labor involved in dismantling each weir board.

数の位置へ挿通し得るようになつている。 In Figures 1 and 2, the formwork device that forms the divided pieces A of the two-part box culvert is movable in the width direction by a pair of guide members 1 arranged in parallel in the short side direction of the formwork. It consists of an outer formwork 2 that stands upright, and an inner formwork 3 that is disposed within the outer formwork 2 and spans between the pair of guide members 1, the width of which can be adjusted. Further, a top lid 4 is disposed on the top surface, and an opening/closing lid 7 is provided at the opening in the front direction, which is pivotally supported by a hinge so as to be openable and closable, and is fixed in the closed state by a lock flank 6. There is.
The guide member 1 is made by arranging angle irons back to back and providing a guide gap between the two back surfaces. A sliding elongated hole 8 passing through the guide member 1 is bored in the direction in which the outer end extends from the center of the guide member 1, and a tightening bolt 9 is inserted therethrough. The outer formwork 2 includes a pair of outer weir plate support ribs 10 that are slidably provided in the gap of the guide member 1, an intermediate rib 10' disposed between each of the ribs 10, and a lateral end. It is formed by disposing an outer dam plate 12 on a framework consisting of a thick 11. Said rib 10
Each of the guide members 1 is provided with a retaining pile 13 that is slidably arranged in the gap between the guide members 1 and stands upright (see FIG. 3). Insertion holes for the bolts 9 are formed at the lower ends of the ribs 10 and the retaining piles 13, respectively, and the bolts 9 are inserted into both insertion holes to lock the ribs 10 and the retaining piles 13 in the gaps. I'm starting to do that. The outer formwork 2 supported by such ribs 10 is movable within the range of the elongated hole 8. Furthermore, by tightening the bolt 9 at the desired location, the rib 10 and the retaining stake 13 can be clamped and fixed to the guide member 1. That is, the width of the water channel of the divided pieces to be formed can be adjusted as appropriate.
The inner formwork 3 that can follow the width adjustment of the outer formwork 2 has a main framework consisting of a pair of L-shaped inner weir plate supports 14 and exchangeable frames 15 prepared in a plurality of lengths. have. The framework is formed by connecting both L-shaped supporting members 14 with an exchange frame 15 in a substantially shape. This exchange frame 15 is prepared in advance in a plurality of lengths, and the exchange frame 15 is selectively used so as to match the set width of the inner frame 3 at the fixed position of the outer frame 2. For example, when the outer frame 2 is expanded and fixed in order to increase the width of the divided pieces to be formed, a long l-long exchange frame 15 is used. Also, when making the width smaller, short length
An exchange frame 15 of l' is used (see Figures 4a and b). Further, the lengths of the exchangeable frames 15 such as l and l' are determined according to the movable distance of the outer formwork 2 and the designed thickness of the divided pieces. Such a framework is placed over each guide member 1 within the outer formwork 2, and is fixed to the guide member 1 at its lower end with bolts or the like. Further, at this time, the guide member 1 is connected and fixed by the support member 16 to integrally connect the outer form frame 2 and the inner form frame 3. This support member 16 is made by sandwiching a T-shaped steel in the gap of the guide member 1, and is fixed by a bolt passing through the member. This bolt can be inserted into a plurality of positions in the extending direction of the guide member 1 in preparation for adjusting the width of the inner formwork 3.
このような枠組外周には、多数の補強用構造材
が配されているとともに、内堰板１７が配設され
ている。 On the outer periphery of such a framework, a large number of reinforcing structural members and an inner dam plate 17 are arranged.
以上のように、形成された外型枠２と内型枠３
との内部底面には、Ｈ形鋼の底板１８がそれぞれ
配され、この底板１８面には、適宜間隔をおいて
空気抜き用の追い出し孔１９が設けられている
（第６図ａ，ｂ参照）。この追い出し孔１９によつ
てコンクリート打込時の下方空気は速やかに排気
される。 As described above, the formed outer formwork 2 and inner formwork 3
A bottom plate 18 made of H-shaped steel is disposed on the inner bottom surface of each of the two, and air vents 19 are provided at appropriate intervals on the surface of the bottom plate 18 (see FIGS. 6a and 6b). . The air from below during concrete pouring is quickly exhausted through this expulsion hole 19.
このようにして形成された型枠Ａは、一単位の
型枠Ａとした際、所用単位の型枠Ａを縦方向に接
続して連続打設することができる。 When the formwork A thus formed is made into one unit of formwork A, the required units of formwork A can be connected in the vertical direction and cast continuously.
また、この接続は、あらかじめ各型枠Ａの端部
に装着されたロツククランク６′によつて行なわ
れる（第７図ａ，ｂ参照）。 This connection is also made by means of a locking crank 6' which is mounted in advance on the end of each formwork A (see FIGS. 7a and 7b).
第８図において、この発明による型枠Ａから形
成された分割ピースは、図中Ｐを指標とする点に

バートＢを構成する。 In FIG. 8, the divided pieces formed from the formwork A according to the present invention constitute box culverts B, each of which is arranged symmetrically with respect to a point indicated by P in the figure.
また、分割ピースの高さを変更したい場合に
は、前記底板１８の高さを調節すればよい。 Furthermore, if it is desired to change the height of the divided pieces, the height of the bottom plate 18 may be adjusted.
