Abstract
The utility model provides a reserved hole formwork of feeding and discharging pipes. The utility model is characterized in that: the reserved hole formwork is of a cone frustum shape; the reserved hole formwork comprises an upper end surface and a lower end surface; and the diameter of the upper end surface is larger than the diameter of the lower end surface. The reserved hole formwork of feeding and discharging pipes has a professionally designed structure and can effectively increase the contact surface and binding force between the new concrete and old concrete, facilitates the compact structure of concrete and reinforces the self-waterproof capability of the bottom concrete; furthermore the generation of crack between the new concrete and the old concrete can be prevented and the concrete dropping-off at the part is prevented.
Description
Technical field
The utility model belongs to the form work engineering field of reserving Durchgangshohle in the construction work for the pipeline threading, is specifically related to a kind of hole to be provided template that is used for the upper and lower conduit road of building.
Background technology
In the existing building construction technology, in order between the aspect of building, to reserve the Durchgangshohle in upper and lower conduit road, the general employing in the mode of carrying out being provided with when aspect is built template reserves this upper and lower conduit road Durchgangshohle, employed template is than the cylindrical template of upper and lower conduit road diameter about greater than 10cm, this hole to be provided template is removed after aspect builds carrying out.When but this kind is formed at the flooring compensating concrete construction after carrying out pipe laying of cylindrical hole to be provided on the aspect, concrete vibrating leakiness, the inconvenient operation of vibrating simultaneously.Near and the concrete water-proof weak effect the floor face upper and lower conduit road.Caking property is relatively poor between the new-old concrete, causes after-pouring concrete obscission easily.
The utility model content
The utility model provides a kind of reasonable in design, can effectively increase the contact surface of new-old concrete and the upper and lower conduit road hole to be provided template of adhesion stress, and it is closely knit that it is convenient to concrete vibration, and underplate concrete is strengthened from waterproof ability; And can prevent the generation in crack between the new-old concrete, stopped the concrete obscission in this place.
The technical scheme that the utility model adopted is as follows:
A kind of upper and lower conduit road hole to be provided template is characterized in that described hole to be provided template is a circular cone shape, and it has a upper surface and a lower surface, and the diameter of described upper surface is greater than the diameter of lower surface.
Specifically, the frustum of a cone that is formed in one of described hole to be provided template.
The described frustum of a cone is that split is provided with structure, and it cuts apart formation two parts along the longitudinal cross-section, center.
The upper surface diameter of the described frustum of a cone is than the big 30cm of upper and lower conduit road diameter.
The lower surface diameter of the described frustum of a cone is than the big 10cm of upper and lower conduit road diameter.
This upper and lower conduit road hole to be provided template adopts the formwork structure of circular cone structure, with the upper strata aperture area expansion of hole to be provided, is convenient to the operation of vibrating, and concrete waterproof ability is strengthened.Carry out concrete when compensation behind pipe laying, it is comparatively convenient construct, can make concrete and the enhancing of the adhesion between old concrete after the compensation.
The beneficial effects of the utility model are, the reasonable in design of this upper and lower conduit road hole to be provided template can effectively increase the contact surface and the adhesion stress of new-old concrete, and it is closely knit that it is convenient to concrete vibration, and underplate concrete is strengthened from waterproof ability; And can prevent the generation in crack between the new-old concrete, stopped the concrete obscission in this place.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
The specific embodiment
As shown in Figure 1, this upper and lower conduit road hole to be provided template 11 is a circular cone shape, it has a upper surface 11 and a lower surface 12, the diameter D1 of described upper surface is greater than the diameter D2 of lower surface, the macromolecular material structure that this hole to be provided template can be formed in one more can form two-part split type macromolecular material structure for cutting apart along the longitudinal cross-section, center.The upper surface diameter of its frustum of a cone is than the big 30cm of upper and lower conduit road diameter, and the lower surface diameter of the frustum of a cone is than the big 10cm of upper and lower conduit road diameter.During construction, the upper surface of this hole to be provided template is positioned at floor top, and the lower surface is positioned at the floor bottom.
Claims (5)
