Abstract
The utility model relates to a distance sleeve for shuttering, which is characterized in that the sleeve 1 is the rigid body, and the diameter of the inner hole 6 of the sleeve is equal to or slightly greater than the outer diameter of the draw rod of the shuttering; the both ends 8 of the sleeve are cone-shaped, and the cone bottom 9 is the end face of the sleeve; stiffening ribs 10 are arranged in the sleeve. When the stiffening ribs are sheathed on the draw rod of the shutting and used as the distance sleeves of the shuttering on both sides, the installation quality of the shuttering and the pouring quality of concrete components can be improved.
Description
The utility model relates to a kind of Distance sleeve for shuttering.
At present, at fluid concrete member (as wall, post, beam etc.) before during mounting template, in order to ensure the working size between two side templates, normally adopt good mao bamboon pipe of on-the-spot saw or plastic pipe sleeve at pull bar on the position between two side templates.The subject matter of being brought of constructing like this is: 1) be difficult to guarantee installation dimension, thereby influence the casting quality of concrete component.This is because bamboo trunk is a natural plants, and dimensioned moulding that can not be in accordance with regulations also is difficult to bear desired working strength; Plastic pipe has flexibility usually, and is flexible.Therefore, when bamboo trunk or plastic pipe during, often can't guarantee being parallel to each other of working size between two side templates and two side templates as the thimble between two side templates.2) rate of recovery of formwork tie is low.This be since saw down bamboo trunk or the end face of plastic pipe be difficult to closely contact with the template face, therefore, cement paste easily in this slit inflow pipe, thereby formwork tie can't be deviate from when dismantling.
The purpose of this utility model is that a kind of Distance sleeve for shuttering will be provided, and when it is enclosed within formwork tie as the thimble of two side templates, will help improving the installation quality of template.
Distance sleeve for shuttering of the present utility model is to constitute like this, and this sleeve pipe is a rigid body, and the diameter of bore of sleeve pipe equals or be slightly larger than the external diameter of formwork tie.
Below in conjunction with drawings and Examples the utility model is specifically described.
Fig. 1 is the embodiment organigram, and Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is an embodiment user mode schematic diagram (vertical view).1 is Distance sleeve for shuttering among the figure, and 2 is template, and 3 is purlin in the template, and 4 is the outer purlin of template, and 5 is formwork tie, and 7 is lock nut.
With reference to accompanying drawing, embodiment of the present utility model comprises sleeve pipe 1, and this sleeve pipe is a rigid body, and endoporus 6 diameters of sleeve pipe equal or be slightly larger than the external diameter of formwork tie; The both ends 8 of sleeve pipe are tapered, and taper bottom surface 9 is a box face; Be provided with reinforcing rib 10 in the union body.
The utlity model has following remarkable advantage: 1) this product is processed into by job requirement Type has accurately dimensional accuracy and enough strength and stiffness, thereby can make the template after the installation Be in best duty. 2) both ends of the surface are smooth, contact closely energy during work with the template face Prevent that the cement mortar of pouring into a mould from entering cannula cavity, thereby guarantee the recovery of form tie. 3) this cover Pipe can steel bar be reinforcement, adopts cement and sand to be prefabricated into. Not only sufficient raw becomes This is low, and is convenient to mechanization production, improves work efficiency. Applying of this sleeve pipe can be saved Approximately a large amount of mao bamboons and plastic tube are effective measures that economize on resources.
