Description
Technical field
The auxiliary work-piece that a kind of precast concrete block for building is constructed as cover to reinforcement is the utility model is related to, specifically
Say, be a kind of multi-functional precast concrete block.
Background technology
At present, it is necessary to ensure that the distance between bar-mat reinforcement and template are fixed value, i.e., during cover to reinforcement construction
The thickness of guarantee cover to reinforcement is needed, what is be usually taken is the mode of the placed longitudinally cement support on reinforcing bar.
Chinese patent CN102852285A disclosed a kind of Multifunctional reinforcement protective cover cushion block, Fig. 1 on January 2nd, 2013
For the structural representation of the cushion block of concrete bar protective layer in the known Chinese patent CN102852285A.Wherein multi-functional bar
Protective layer cushion block includes rectangular matrix 1, and the thickness of matrix 1 and the thickness of cover to reinforcement match, the inner end of matrix 1
Groove 2 is provided with, the depth of groove 2 and the diameter of reinforcing bar match, and the inner end top of matrix 1 is provided with fixture block 3, fixture block 3
Bottom extends to the front of groove 2.Although the rectangular matrix 1 is applicable to the job site of different wall thicknesses,
The groove structure of this oblique slot type there is unstability, causes cushion block of concrete bar protective layer to fix insecure, easy generation position in itself
Shifting, frangibility, place the problem of inconvenient, it is impossible to which control slab thickness meets design requirement well.
Therefore known cushion block of concrete bar protective layer there are problems that above-mentioned a variety of inconvenience and.
The content of the invention
The purpose of this utility model, it is to propose that a kind of multi-functional concrete for being used for the original cushion block of concrete bar protective layer of replacement is pre-
Clamp dog.
To achieve the above object, technical solution of the present utility model is：
A kind of multi-functional precast concrete block, including section are in the precast concrete block of inverted isosceles trapezoid, it is characterised in that：
The section is recessed in the precast concrete block of inverted isosceles trapezoid, being respectively provided with one in the middle part of bottom and in the middle part of bottom thereon
Groove, the depth of groove and the diameter of reinforcing bar match, and can house reinforcing bar, the height of the precast concrete block of isosceles trapezoid in groove respectively
Match with the thickness of cast-in-place concrete floor, be caught in a groove the groove after reinforcing bar Nei and fill the cast-in-place coagulation of reinforcing bar protection
Soil.
Multi-functional precast concrete block of the present utility model can also be further achieved by the following technical measures.
Foregoing multi-functional precast concrete block, wherein the reinforcing bar is the plate face reinforcing bar or plate bottom steel of cast-in-place concrete floor
Muscle.
Foregoing multi-functional precast concrete block, wherein upper bottom length >=120mm of the precast concrete block of the isosceles trapezoid.
Foregoing multi-functional precast concrete block, wherein bottom length >=60mm of the precast concrete block of the isosceles trapezoid.
Foregoing multi-functional precast concrete block, wherein the thickness of the precast concrete block of the isosceles trapezoid is the design of cast-in-situ floor
Thickness.
Foregoing multi-functional precast concrete block, wherein the concrete material and cast-in-situ floor of the precast concrete block of the isosceles trapezoid
The same label of concrete.
After adopting the above technical scheme, multi-functional precast concrete block of the present utility model has advantages below：
1st, precast concrete block moulding is stable, simple in construction, easy to make, is adapted to largely be given birth to according to architectural engineering requirement
Production；
2nd, precast concrete block installation simple and fast, fixation, instead of original cushion block of concrete bar protective layer, can not only play steel
The effect of muscle stirrup, moreover it is possible to preferably control cover to reinforcement, floor elevation and slab thickness to meet design and code requirement.

Embodiment
With reference to embodiments and its accompanying drawing illustrates further to the utility model.
Embodiment 1
Multi-functional precast concrete block of the present utility model, including section are in the precast concrete block of inverted isosceles trapezoid.
Referring now to Fig. 2, Fig. 2 is the multi-functional precast concrete block structural representation of the utility model embodiment.As illustrated,
In in the precast concrete block 1 of inverted isosceles trapezoid, in the middle part of bottom and bottom middle part is respectively provided with a groove 2 thereon, recessed in the section
The depth of groove and the diameter of reinforcing bar 3 match, and can house reinforcing bar in groove respectively, the height of the precast concrete block of isosceles trapezoid is with showing
The thickness of pouring concrete floor matches, and is caught in a groove the groove after reinforcing bar 3 Nei and fills reinforcing bar protection cast-in-place concrete.Institute
State the plate face reinforcing bar or reinforcement that reinforcing bar 3 is cast-in-place concrete floor.The upper bottom length of the precast concrete block 1 of the isosceles trapezoid
For 120mm.The bottom length of the precast concrete block 1 of the isosceles trapezoid is 60mm.The precast concrete block of the isosceles trapezoid（1）Thickness
