Abstract
The utility model relates to a positioning ring for a protruding bar of a prefabricated component, which belongs to the technical field of production of prefabricated components of construction engineering and comprises a cone frustum and a cylinder. The cone frustum and the cylinder are coaxially and integrally connected, a central through hole is axially disposed on the positioning ring, the inner diameter of the through hole matches with the diameter of the protruding bar, and the outer diameter of the bottom end of the cone frustum matches with the size of an open pore on a formwork. The positioning ring for the protruding bar of the prefabricated component has the various advantages of easiness in form stripping, zero mud leakage and capability of guaranteeing positioning of the protruding bar. During usage, the pore with the size matching with the diameter of the cone frustum is tapped on the formwork at the center of the protruding bar, the cone frustum of the positioning ring is plugged into the pore of the formwork, the cylinder of the positioning ring is attached to the formwork, and the protruding bar extends out from the central through hole of the positioning ring.
Description
Technical field
The utility model belongs to the prefabricated components production technical field of architectural engineering, particularly prefabricated components protruding bar centring ring structural design.
Background technology
Concrete prefabricated element have many reinforcing bars to stretch out template on the side form during some parts production, and status requirement is accurate in producing.If perforate is less on the side form (bigger slightly than bar diameter), because many reinforcing bars will withdraw from side form together, form removal is difficulty quite, even does not tear open not come out; The conventional practice is: wide-bore on the side form, and side form comes out with regard to removable, but the reinforcing bar position of going out is difficult to guarantee, and the hole is big, and spillage is serious during concreting.
The utility model content
The purpose of the utility model is in order to solve the member exposed steel bar location problem difficult with form removal, a kind of prefabricated components protruding bar centring ring to be provided, have form removal easily, spillage not, and can guarantee the plurality of advantages of protruding bar location.
A kind of prefabricated components protruding bar centring ring that the utility model provides; It is characterized in that; This centring ring is made up of a coaxial frustum of a cone and cylinder that is linked to be integral body; This centring ring has central through hole vertically, and the internal diameter of this through hole matches with stretching out reinforcing bar external diameter, and perforate matches on the bottom external diameter of this frustum of a cone and the template.
The diameter of above-mentioned central through hole is confirmed according to the diameter of stretching out reinforcing bar, generally than the big 0.2-1.5mm of reinforcing bar actual outside diameter; The big end external diameter of the frustum of a cone is than the big 6～11mm of centre bore, and the frustum of a cone is high by 15～20, and the tapering of the frustum of a cone is 1/10; The external diameter of cylinder is than the big 10～12mm of the big end external diameter of the frustum of a cone, the high 4～6mm of cylinder.
When this centring ring used: on the template of protruding bar center, open a hole onesize with the round platform diameter, the round platform of centring ring is partly filled in the pattern hole, the cylinder of centring ring was close to template, and overhanging reinforcing bar stretches out from centre bore.
Use the benefit of this centring ring to be: reinforcing bar closely contacts with template through centring ring, does not have the slit between reinforcing bar and the template basically, so can never spillage during concreting; Centring ring is thrown off with template earlier during form removal, forms macropore, and many reinforcing bars are just easily deviate from template.Centring ring is made truncated cone in addition, helps on template, boring circular hole with matching, and can guarantee the location of protruding bar.
Description of drawings
Fig. 1 is the utility model centring ring sketch map.
Fig. 2 uses scheme of installation for the utility model centring ring.
Fig. 3 is for using the member form removal sketch map of centring ring.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this setting circle and method for using thereof are further specified:
The structure of the prefabricated components protruding bar centring ring of the utility model is as shown in Figure 1: this centring ring is made up of a coaxial frustum of a cone 1 and cylinder 2 that is linked to be integral body; This centring ring has central through hole 3 vertically; The internal diameter of this central through hole matches with stretching out bar diameter, and perforate matches on the bottom external diameter of this frustum of a cone and the template.
The internal diameter of above-mentioned central through hole 3 is confirmed according to the diameter of stretching out reinforcing bar, generally than the big 0.2-1.5mm of reinforcing bar actual outside diameter; The big end external diameter of the frustum of a cone 1 is than the big 6～11mm of centre bore, and the high 15～20mm of the frustum of a cone, the tapering of the frustum of a cone are 1/10.
The external diameter of above-mentioned cylinder 2 is than the big 10～12mm of round platform, the high 4～6mm of cylinder.
The centring ring of the utility model can be with rubber or with there being certain flexible other material moulding to form.
Embodiment
Table 1 is 8 kinds of embodiment, has enumerated out the construction size of the corresponding centring ring of all size extending screw reinforcing bar, and the diameter of perforate on the template.
Table 1
The centring ring of above-mentioned each embodiment adopts vulcanized rubber or tartan moulding to make.
The utility model centring ring method for using is as shown in Figure 2: what a and the onesize hole of the frustum of a cone diameter component template (side form 5) open in the protruding bar center; The frustum of a cone 1 of centring ring is filled in the pattern hole; The cylinder 2 of centring ring is close to template, and overhanging reinforcing bar 4 stretches out from the centring ring centre bore.
Claims (3)
1. prefabricated components protruding bar centring ring; It is characterized in that; This centring ring is made up of a coaxial frustum of a cone and cylinder that is linked to be integral body; This centring ring has central through hole vertically, and the internal diameter of this through hole matches with stretching out bar diameter, and perforate matches on the big end external diameter of this frustum of a cone and the template.
2. prefabricated components protruding bar centring ring as claimed in claim 1 is characterized in that the internal diameter of said central through hole is than the big 0.2-1.5mm of reinforcing bar actual outside diameter; The big end external diameter of the frustum of a cone is than the big 6～11mm of centre bore, and the high 15～20mm of the frustum of a cone, the tapering of the frustum of a cone are 1/10.
