Perhaps preferably, described circular opening is perpendicular to the upper surface of body, and described circular opening coincides with the central point of upper surface in the center of circle of upper surface.
More preferably, the center line of arc groove passes the central point of body soffit, and the subpoint of the center of circle of upper surface circular opening on soffit coincides with arc groove at the central point of soffit projection.
Perhaps more preferably, be provided with manhole between described arc groove and circular opening.
Further preferably, the diameter of described manhole is less than the diameter of circular opening.
Perhaps more preferably, the side of described body is provided with a pair of tied silk groove symmetrically.
Further preferably, described tied silk groove the projection on soffit with arc groove the projection on soffit vertical.
Perhaps more preferably, described body is the round platform body.
Further preferably, the height of described round platform body is 23mm, and the upper surface diameter is 18mm, and the soffit diameter is 30mm.
Reinforcement cover pad described in the utility model; the reinforcing bar two ends that are used for shuttering supporting can be inserted respectively the circular opening of body upper surface; the support shuttering that again bearing bar is connected with wall, beam steel can be realized firm connection the between body and wall, beam forms.Directly body is faced up greatly, the slab muscle is stuck in arc groove props up pad as plate lower rebar topping, body and ∏ type are supported to combine can be used as plate upper reinforcement topping and prop up pad.Because the construction size of body is consistent with the related specifications requirement, therefore can effectively guarantee the distance between reinforcing bar and wall, plate, beam forms, the utility model is simple in structure, is common to concrete wall, plate, each class A of geometric unitA of beam, and practicality is stronger.

[specific embodiment]
Cushion block of concrete bar protective layer described in the utility model; comprise highly and to be the round platform body 1 of 23mm; the upper surface of round platform body 1 is provided with a circular opening 2; this circular opening 2 extends to round platform body 1 inside; be highly 8mm; and perpendicular to round platform body 1 upper surface, and circular opening 2 coincides with the central point of body 1 upper surface in the center of circle of upper surface.
when this cushion block is applied to control wall, during beam side reinforcement cover, first 7 colligations of structural skeleton reinforcing bar are fixed, a round platform body 1 (during circular opening 2 is inserted respectively at bearing bar 6 two ends) then is installed respectively at the two ends of shuttering supporting reinforcing bar 6, again with bearing bar 6 perpendicular to the structure reinforcing bars colligation, be fixed on the protection reinforcing bar, at last with wall, beam forms 8 assembly units, allowing template 8 fit tightly on the soffit of round platform body 1 is fixed, can realize fixing distance between reinforcing bar and template 8 inner surfaces, can realize again fixing two template 8 spacings.
The present embodiment is substantially the same manner as Example 1, and difference is that the present embodiment is provided with the arc groove 3 of perforation soffit to round platform body 1 inside on round platform body 1 soffit relative with upper surface.Arc groove 3 intersects with round platform body 1 and forms arc, and the height of this arc is 8mm, and the two ends of this arc respectively have one section straight line and extend the limit, and it is 3mm that this straight line extends the limit.
When this cushion block is applied to vertical or horizontal force reinforcing bar 9 array pitch of knee wall concrete component, the bearing bar 6 that the cushion block body is installed is placed between two placing of reinforcements and will be vertical or level embed arc grooves 3 to steel bar stress 9.
The present embodiment is substantially the same manner as Example 2, and difference is to be provided with manhole 4 between the described arc groove 3 of the present embodiment and circular opening 2, and the diameter of this manhole 4 is less than the diameter of circular opening 2, and the height of this manhole 4 is 7mm.
Realize that when the present embodiment embodiment 2 is described fixedly the time, available colligation tied silk and steel bar stress colligation of passing manhole 4 fixed.
When this cushion block is applied to Bars In Poured Concrete Slab bottom steel bar stress and supports, the upper surface of round platform body 1 is contacted with template surface, steel bar stress is embedded in the set arc groove 3 of body soffit, pass from circular opening 2 and tie a knot with tied silk again, the tied silk after knotting is passed the firm colligation of manhole 4 and plate bottom steel bar stress together.The present embodiment can realize that between steel bar stress and template, spacing is stable, and cushion block supports firm, to guarantee the thickness of building of cover concrete.
When this cushion block is applied to the support of plate upper reinforcement 11, the two ends of preprepared ∏ shape bearing bar 10 are inserted respectively in the circular opening 2 on round platform body 1 top, and utilize tied silk with plate upper reinforcement 11 and the 10 horizontal edge colligations of ∏ shape bearing bar, cushion block body soffit and template 8 be because having increased contact area, can realize the stability of ∏ shape bearing bar 10 on 8 of templates.
The present embodiment and embodiment 1 or 2 or 3 basic identical, difference is that the present embodiment is provided with a pair of tied silk groove 5 symmetrically at the side of round platform body 1, the projection of this tied silk groove 5 on the bottom surface of the projection on bottom surface and arc groove 3 is vertical.
When reinforcing bar 12 passes round platform body 1 radially during circular opening 2, available binding directly from tied silk groove 5 tying fix, also binding can be passed from manhole 4, then tying is fixed from tied silk groove 5.
