Abstract
The utility model discloses a flexible core-pulling internal mold, and solves the technical problems of an unreasonable structure and serious waste of the conventional internal mold. The internal mold comprises a first right-angle bow-shaped internal mold plate (1), a second right-angle bow-shaped internal mold plate (6), a telescopic supporting rod (3) and hinges, wherein one end of the first right-angle bow-shaped internal mold plate (1) is connected with one end of the second right-angle bow-shaped internal mold plate (6) through a first hinge (4); the other end of the first right-angle bow-shaped internal mold plate (1) is connected with one end of the telescopic supporting rod (3) through a second hinge (7); the other end of the second right-angle bow-shaped internal mold plate (6) is connected with the other end of the telescopic supporting rod (3) through a third hinge (8); and a pushing, supporting, pulling and closing mechanism (5) is arranged on the telescopic supporting rod (3). The internal mold ensures the precast quality of a beam body, can be reused, and improves production efficiency and economic benefits.
Description
Technical field
The utility model relates to a kind of civil engineering mould, particularly a kind of case beam (cored slab) employed internal mold when prefabricated that is used for.
Background technology
Internal mold generally adopted wooden model or inflated rubber capsule when case was beam prefabricated, and the use of wooden model often is disposable, causes significant wastage, and aerated capsule is because the wayward beam body top plate thickness inequality that causes of come-up, quality that can't the guard box beam.
Summary of the invention
The utility model provides a kind of movable internal mold of loosing core to solve existing inner membrance unreasonable structure and the serious technical problem of waste.
The utility model overcomes the above problems by following scheme:
A kind of movable internal mold of loosing core, comprise the arc inner formword in first right angle, the arc inner formword in second right angle, telescopic supporting rod and hinge, one end of the arc inner formword of one end of the arc inner formword in first right angle and second right angle links together by first hinge, the other end of the arc inner formword in first right angle links together by an end of second hinge and telescopic supporting rod, the other end of the arc inner formword in second right angle links together by the other end of the 3rd hinge and telescopic supporting rod, and telescopic supporting rod is provided with and pushes away support drawing mechanism.
The arc inner formword of the arc inner formword in described first right angle and second right angle is provided with respectively touches the plate internal overarm support.
The utility model provides a kind of movable internal mold of loosing core, and has not only guaranteed the prefabricated quality of beam body but also can reuse, improved production efficiency, has created good economic benefits.
Description of drawings
Fig. 1 is the structural representation of the utility model under softened state
Fig. 2 is that the utility model is at the structural representation of taking out under the state of closing.
The specific embodiment
A kind of movable internal mold of loosing core, comprise the arc inner formword 1 in first right angle, the arc inner formword 6 in second right angle, telescopic supporting rod 3 and hinge, one end of the arc inner formword 6 of one end of the arc inner formword 1 in first right angle and second right angle links together by first hinge 4, the other end of the arc inner formword 1 in first right angle links together by the end of second hinge 7 with telescopic supporting rod 3, the other end of the arc inner formword 6 in second right angle links together by the other end of the 3rd hinge 8 with telescopic supporting rod 3, and telescopic supporting rod 3 is provided with and pushes away support drawing mechanism 5.
The arc inner formword 6 of the arc inner formword 1 in described first right angle and second right angle is provided with respectively touches plate internal overarm support 2.
This internal mold has used the umbrella principle, and telescopic supporting rod 3 is equivalent to umbrella frame, push away support drawing mechanism 5 is equivalent to handle of umbrella, by pushing away the Zhi Li and the contraction that inner formword is played in support and drawing that push away of support drawing mechanism 5.During installation the pull bar channel-section steel boosted and with fixing on the fixing iron, telescopic supporting rod 3 is propped up, and can realize formwork support arrangement thereupon, and make internal mold prop up internal geometric size into beam.Be combined into an integral body with 2 internal molds in each case beam, and firm with the steel band colligation, and template adopts adhesive tape closely connected at moveable hinge and seam crossing, prevents spillage.After concrete cast finishes and reaches the form removal condition, unclamp the fixedly bolt of ferropexy end, take off fixedly iron of pull bar, adopt electrical hoist to drag the middle support drawing mechanism 5 that pushes away of template, the reach of core pull bar drives template and shrinks, and the realization template is separated with concrete, thereby core is taken out in beam.
Claims (2)
1. movable internal mold of loosing core, comprise the arc inner formword in first right angle (1), the arc inner formword in second right angle (6), telescopic supporting rod (3) and hinge, it is characterized in that, one end of the arc inner formword of one end of the arc inner formword in first right angle (1) and second right angle (6) links together by first hinge (4), the other end of the arc inner formword in first right angle (1) links together by the end of second hinge (7) with telescopic supporting rod (3), the other end of the arc inner formword in second right angle (6) links together by the other end of the 3rd hinge (8) with telescopic supporting rod (3), and telescopic supporting rod (3) is provided with and pushes away support drawing mechanism (5).
2. a kind of movable according to claim 1 internal mold of loosing core is characterized in that the arc inner formword of the arc inner formword in described first right angle (1) and second right angle (6) is provided with respectively touches plate internal overarm support (2).
