Description

本発明は補修する現場での生コンクリートの製造方法および補修する現場への生コンクリート原料の輸送袋に関する。   The present invention relates to a method for producing ready-mixed concrete at the site to be repaired and a transport bag for raw concrete raw material to the site to be repaired.

従来、補修する現場で生コンクリートを使用する場合、生コンクリートを生コン工場でコンクリートミキサー車に砂や砂利等のコンクリート骨材、セメント、水をそれぞれ計量して投入し、混練しながら補修現場へ輸送しているため、輸送時間によって生コンクリートの品質の劣化が生じるという欠点があるとともに、水を加えた生コンクリートの輸送であるため、重量が重く、輸送効率が悪いという欠点があった。   Conventionally, when using ready-mixed concrete at the repair site, the ready-mixed concrete is weighed into concrete mixer trucks such as sand and gravel, cement, and water at the ready-mix factory, and transported to the repair site while mixing. Therefore, there is a drawback that the quality of the ready-mixed concrete is deteriorated depending on the transport time, and the transport of ready-mixed concrete to which water is added, so that the weight is heavy and the transport efficiency is poor.

この欠点を解消するために、生コンクリートを使用する補修現場へコンクリート骨材やセメントを輸送して、その場で生コンクリートを製造することも考えられているが、現場でコンクリート骨材やセメントの計量をしなければならず、その作業が大変で、生コンクリートの専門家がいないと最適な生コンクリートの製造が難しいという欠点があった。   In order to eliminate this drawback, it is also considered to transport concrete aggregate and cement to the repair site that uses ready-mixed concrete and manufacture ready-mixed concrete on the spot. It has to be weighed and the work is difficult, and there is a disadvantage that it is difficult to produce optimum ready-mixed concrete without a ready-mixed concrete specialist.

また、セメント硬化剤を用いる生コンクリートの製造は、現場に熟練者がいないと、使用することができなかった。   Moreover, the production of ready-mixed concrete using a cement hardener could not be used unless there was a skilled person on site.

以下、図面に示す本発明を実施するための形態により、本発明を詳細に説明する。   Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings.

図１ないし図１４に示す本発明を実施するための第１の形態において、１は補修現場へトラック等で輸送されるコンクリート原料を輸送する輸送袋で、このコンクリート原料輸送袋１はクレーン２等で吊り上げられる吊り紐３、３が設けられた上部が開口４し、底面中央部に開閉手段５で開閉できる排出口６が形成された、あらかじめ設定された量の砂や砂利等のコンクリート骨材７が収納されたコンクリート原料収納袋８と、このコンクリート原料収納袋８内に収納されたコンクリート骨材７に最適な量のセメント９が収納され、後端部が折りたたまれて閉じることができるセメント収納袋１０と、このセメント収納袋１０に収納された前記セメント９と前記コンクリート原料収納袋８に収納されたコンクリート骨材７で作られる生コンクリートを最適に硬化できる量のセメント硬化剤１１とで構成されている。なお、第１の形態では、セメント硬化剤１１は、図１で示すようにセメント９と共にセメント収納袋１０に収納されている。   In the first embodiment for carrying out the present invention shown in FIGS. 1 to 14, reference numeral 1 denotes a transport bag for transporting a concrete raw material transported by truck or the like to a repair site. The concrete raw material transport bag 1 is a crane 2 or the like. A concrete aggregate of a predetermined amount of sand, gravel, etc., in which the upper part provided with the hanging straps 3 and 3 that are lifted by the opening 4 has an opening 4 and a discharge port 6 that can be opened and closed by the opening and closing means 5 is formed in the center of the bottom. 7 is stored in the concrete raw material storage bag 8 and the concrete aggregate 7 stored in the concrete raw material storage bag 8, and an optimal amount of cement 9 is stored, and the rear end portion is folded and closed. Raw concrete made of a storage bag 10, the cement 9 stored in the cement storage bag 10 and the concrete aggregate 7 stored in the concrete raw material storage bag 8 It is composed of a quantity of cement curing agent 11 that can be optimally cured over bets. In the first embodiment, the cement hardener 11 is stored in the cement storage bag 10 together with the cement 9 as shown in FIG.

このようなコンクリート原料輸送袋１は、工場でコンクリート原料収納袋８の排出口６を開閉手段５で閉じ、上部の開口４よりあらかじめ設定された量の砂や砂利等のコンクリート骨材７を収納し、このコンクリート骨材７に最適な量のセメント９およびセメント硬化剤１１が収納され、開口部１２を紐１３でフック１４に係止できるように取付けられたセメント収納袋１０を、前記コンクリート原料収納袋８内に収納して、該コンクリート原料収納袋８の上部の開口４をロープ１５で縛り、閉じることによりコンクリート原料を詰める作業工程１６が完了する。   In such a concrete raw material transport bag 1, the outlet 6 of the concrete raw material storage bag 8 is closed by the opening / closing means 5 in the factory, and a predetermined amount of concrete aggregate 7 such as sand or gravel is stored from the upper opening 4. A cement storage bag 10 in which an optimal amount of cement 9 and cement hardener 11 are stored in the concrete aggregate 7 and attached so that the opening 12 can be locked to the hook 14 by a string 13 is used as the concrete raw material. The operation process 16 of filling the concrete raw material is completed by storing in the storage bag 8, tying the opening 4 at the top of the concrete raw material storage bag 8 with the rope 15 and closing it.

このコンクリート原料を詰める作業工程１６後に、図１１に示すようにコンクリート原料収納袋８の吊り紐３、３にクレーン２等のフック１４を係合させ、トラック１７の荷台へ積み込み、コンクリートで補修する現場へ輸送し、同様に吊り紐３、３にクレーン２等のフック１４を係合させ、荷台より下ろす輸送工程１８を行なう。   After the work process 16 for filling the concrete raw material, as shown in FIG. 11, hooks 14 such as the crane 2 are engaged with the hanging straps 3 and 3 of the concrete raw material storage bag 8, loaded on the loading platform of the truck 17, and repaired with concrete. Transporting to the site, similarly, the hook 14 such as the crane 2 is engaged with the hanging straps 3, 3, and the transporting process 18 of lowering from the loading platform is performed.

この輸送工程１８の荷下ろし時に、コンクリートミキサー車等の混練機１９に直接コンクリート原料収納袋８内のコンクリート原料を投入したり、現場に荷下ろしされたコンクリート原料収納袋８を同様にクレーン２等で吊り上げ、コンクリートミキサー車等の混練機１９に投入し、しかる後、あらかじめ設定された前記コンクリート原料収納袋８内に収納されたコンクリート原料に最適な量の水２０を加えて混練する混練工程２１を行なうことにより、補修現場で必要とされる最適な生コンクリート２２が製造される補修現場での生コンクリートの製造方法２６を行うことができる。   At the time of unloading in the transporting process 18, the concrete raw material in the concrete raw material storage bag 8 is directly fed into a kneader 19 such as a concrete mixer truck, or the concrete raw material storage bag 8 unloaded at the work site is similarly applied to the crane 2 or the like. The kneading step 21 is carried out by adding the optimal amount of water 20 to the concrete raw material stored in the concrete raw material storage bag 8 set in advance. By performing the above, it is possible to perform the ready-mixed concrete manufacturing method 26 at the repair site where the optimum ready-mixed concrete 22 required at the repair site is manufactured.

なお、コンクリートミキサー車等の混練機１９へコンクリート原料を投入する場合、コンクリート原料収納袋８の上部の開口４を開放し、セメント収納袋１０の紐１３も、図１２に示すように同時にクレーン２等のフック１４に係止させることにより、コンクリート原料収納袋８内に収納されているコンクリート骨材７が排出されると、セメント収納袋１０の下端部が自動的に開口して、コンクリートミキサー車等の混練機１９内へ投入される。   When the concrete raw material is charged into the kneader 19 such as a concrete mixer truck, the opening 4 at the top of the concrete raw material storage bag 8 is opened, and the string 13 of the cement storage bag 10 is also simultaneously connected to the crane 2 as shown in FIG. When the concrete aggregate 7 stored in the concrete raw material storage bag 8 is discharged by being engaged with a hook 14 such as a concrete mixer truck, the lower end of the cement storage bag 10 is automatically opened, and the concrete mixer truck Or the like into the kneading machine 19.
