Abstract
It is a kind of for isolating the parts of main reinforcement and template that the utility model provides, and being cube shaped concrete block is cushion block, and stretch out a front end with the straight shape support rod of crotch from the centre of concrete block.The utility model structure is very simple, and can guarantee isolation effect and exposed without rod head, corrosion of steel bar is little.
Description
Technical field
The utility model relates to a kind of widget of using when reinforced concrete lining layer is constructed, and particularly when construction is for isolating the parts of main reinforcement and template.
Background technology
Current; during reinforced concrete lining layer, the general steel form that adopts is as building moulding form; in order to ensure the thickness of concrete cover composite demand between main reinforcement and template; need between reinforcing bar and template, there is isolated part; as handstone of pad or concrete block, or reinforcing rod is supported, an inner reinforcing bar of support in interval; prevent from being close to after reinforcing bar from being pushed by concrete the effect of template, the Minimal Protective layer thickness of reinforcing bar after concreting is met the requirements.But adopt the deficiency of single handstone or concrete block pad to be, reinforcing bar slightly shakes and will make handstone or concrete come off, and when concreting is made firm by ramming, can push reinforcing bar, makes it press close to template, is difficult to arrive isolation effect.The deficiency that adopts reinforcing rod to support is that the termination of reinforcing rod withstands template, concrete cannot encase reinforcing rod completely, demoulding follower head can be exposed in air, malaria can cause corrosion to reinforcing rod, and As time goes on, corrosion penetration is by increasing, finally on body of wall, form aperture, and further cause the corrosion of inner reinforcing bar, and finally affect the stress performance of whole reinforced concrete structure, when serious, also can cause quality accident.
Utility model content
The utility model aim to provide a kind of guarantee isolation effect and exposed without rod head, corrosion of steel bar is little for isolating the parts of main reinforcement and template.The utility model is realized by following scheme:
For isolating parts for reinforcing bar and template, being cube shaped concrete block is cushion block, and stretches out a front end with the straight shape support rod of crotch from the centre of concrete block.
For being suitable for more at large each execution conditions, described every edge lengths of concrete pad is more than 4 centimetres.
Compare with existing partition method and the parts that adopt, the utility model structure is very simple, and this parts, the concrete pad of front end is used for isolating reinforcing bar and template, the rib stretching out is both for shoring concrete pad, make in construction cushion block be difficult for loosening and distortion and come off, thereby play good isolation effect; This root rib also can doublely be done tension rib or the bearing rod of main body reinforcing bar simultaneously.Adopt in addition the utility model, during demoulding, there is no directly exposed steel bar end, will greatly reduce the construction quality risk of bringing because of corrosion.
Accompanying drawing explanation
The structural representation of Fig. 1: embodiment 1
The schematic diagram when isolated part of Fig. 2: embodiment 1 is used for constructing.
The specific embodiment
embodiment 1
As shown in Figure 1 a kind of for isolating the parts of main reinforcement and template, being cube shaped concrete block 1 is cushion block, from the centre of concrete block 1, stretches out a front end with the straight shape support rod 3 of crotch 2, the length of concrete block 1 is 4 centimetres.
During construction, as shown in Figure 2, the stud 4 of main reinforcement and horizontal bar 5 intersect lace by tied silk, after ectonexine reinforcing bar lace, above-mentioned parts are installed again.When above-mentioned parts are installed, by concrete pad 1 pad between the main reinforcement and template 6 of internal layer, support rod 3 and crotch 2 colligations are fixed on the main reinforcement of inside and outside layer, concrete pad 1 just can not drop on the one hand, make two-layer main reinforcement connect into integral body by support rod 3, overcome the deficiency in traditional construction.
Claims (2)
