Abstract

The invention relates to the technical field of civil engineering, in particular to a form board fastening device for facilitating control on a large-thickness concrete protecting layer. The form board fastening device for facilitating control on the large-thickness concrete protecting layer comprises an inner opposite-pull rod, an outer opposite-pull rod, a circular-truncated-cone-shaped nut and a disc-shaped nut, wherein the outer opposite-pull rod penetrates in a form board and is detachably connected with the inner opposite-pull rod through the circular-truncated-cone-shaped nut; and the length of the circular-truncated-cone-shaped nut is matched with the thickness of the concrete protecting layer so that thicknesses of different concrete protecting layers can be controlled effectively. When the form board is detached, the circular-truncated-cone-shaped nut is detached, a hole in the location of the circular-truncated-cone-shaped is chiseled and is filled with epoxy mortar, the inner opposite-pull rod does not need to be taken out, defects on the quality of concrete due to drawbacks of the traditional technology are greatly avoided, according to the structure with the inner opposite-pull rod, the outer opposite-pull rod and the circular-truncated-cone-shaped nut, the opposite-pull rods can be customized according to the thickness of thickness of a wall body, the mounting position of the form board can be limited well by the combination of the opposite-pull rods, and the structural size can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a formwork fastening device which facilitates the control of a large-thickness concrete protective layer. Background technique [0002] At present, when the concrete pouring formwork is installed, for the support of tall and large formwork, the formwork is generally fixed by means of pull screws to avoid overturning or mold explosion on the concrete side pressure formwork. For ordinary concrete structures, PVC pipes are generally placed on the pull screws. After the formwork is removed, the pull screws are pulled out from the PVC pipes, and the reserved pipe holes are sealed. For concrete structures with high requirements for durability and anti-seepage, the above method has a high risk of leakage, and the reliability of the repair method is not high, which will have an adverse effect on the durability of the concrete structure. Especially for marine concrete where the...
