Abstract
The invention discloses a multifunctional prefabricated concrete cushion block. The multifunctional prefabricated concrete cushion block comprises a cushion block body, wherein the cushion block body is a cuboid, the upper end of one side of the cushion block body is provided with a rectangular notch, the inner end of the rectangular notch is provided with a first arch groove, an oblique groove is formed in a position, right below the first arc groove, of the cushion block body, the upper end surface of the oblique groove is inclined upwards, an angle formed between the upper end surface of the oblique groove and the horizontal plane is an acute angle, and the lower end surface of the oblique groove is parallel to the bottom surface of the cushion block body. By adopting the technical scheme, the first arc groove and the oblique groove are reasonable in structure, the distance from the top surface of the cushion block to the first arc groove is identical to the sum of the thickness of a reinforcing steel bar protection layer and the diameter of a reinforcing steel bar, and not only can the thickness of a concrete protection layer between the bottom and the surface of a floor board be guaranteed, but also the thickness of the concrete floor board can be effectively controlled.
Description
Technical field
The present invention relates to concrete pad technical field, be specifically related to a kind of multifunctional precast concrete pad.
Background technology
In reinforced concrete member structure pouring construction, for protection reinforcing bar is because external condition impact does not cause corrosion, guarantee the durability of structure, must there be suitable concrete cover in reinforcing bar outside, can not cross thin again can not be blocked up.Therefore at reinforced concrete member reinforcing bar, set up and need between outer reinforcement and template, put into cushion block when template is installed and control thickness of concrete cover by fixing and bearing bar layer.Its quality is directly connected to the situations such as the bearing capacity of reinforcing bar in concrete work structure, durability, acid and alkali-resistance, fire prevention, and workmanship is played an important role.Common cushion block has cement mortar bedding block, plastic cushion, sheet material etc. at present.But there is the shortcomings such as low, the easy displacement of intensity is broken more in these cushion blocks, can not effectively control the thickness of reinforced concrete protective layer, and most cushion block only can guarantee reinforcing bar hypodermis protective layer thickness, can not guarantee epithelium concrete thickness and thickness of slab.
Summary of the invention
For the deficiency of prior art existence, the object of the present invention is to provide the multifunctional precast concrete pad of a kind of reasonable in design, reliable operation.
For achieving the above object, the invention provides following technical scheme: a kind of multifunctional precast concrete pad, comprise cushion block body, described cushion block body is cuboid, cushion block body one side upper end is provided with rectangular indentation, described rectangular indentation the inner is provided with the first arc groove, described cushion block body be positioned at the first arc groove under position be provided with tipper, the setting that is inclined upwardly of described tipper upper surface, and the angle forming between the upper surface of this tipper and horizontal plane is acute angle, the lower surface of described tipper and cushion block body bottom surface be arranged in parallel.
By adopting technique scheme; the first arc groove, tipper structure arrange rationally; the distance of cushion block body end face to the first arc groove equals thickness of protection tier and adds bar diameter; at the bottom of can guaranteeing floor plate and the thickness of concrete cover of plate face, can effectively control thickness of concrete floor again.
The present invention is further set to: the inner of described tipper is provided with the second arc groove, after this second arc groove is communicated with tipper, forms a complete draw-in groove.By this setting, tipper and the second arc groove arrange rationally, and the second arc groove equals thickness of protection tier to the distance of cushion block body bottom surface, and cushion block body thickness equals slab thickness, work more reliable.
The present invention is also further set to: the upper surface of described tipper and the angle between horizontal plane are 30 °-75 °.By this setting, tipper structure arranges rationally, places reinforcing bar more convenient to operate.
The present invention is also further set to: described the first arc groove and the second arc groove center of circle line parallel.By this setting, the first arc groove and the second arc groove position arrange rationally, work more reliable.
The present invention is also further set to: difference reinforcing bar in described the first arc groove and the second arc groove, described reinforcing bar matches with corresponding groove diameter.By this setting, place reinforcing bar more convenient to operate.
Advantage of the present invention is: compared with prior art; structure setting of the present invention is more reasonable; the first arc groove, tipper structure arrange rationally; the distance of cushion block body end face to the first arc groove equals thickness of protection tier and adds bar diameter; tipper and the second arc groove arrange rationally; the second arc groove to the distance of cushion block body bottom surface equals thickness of protection tier; cushion block body thickness equals slab thickness; at the bottom of can guaranteeing floor plate and the thickness of concrete cover of plate face, can effectively control thickness of concrete floor again.
Below in conjunction with Figure of description and specific embodiment, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
The specific embodiment
Referring to Fig. 1, a kind of multifunctional precast concrete pad disclosed by the invention, comprise cushion block body 1, described cushion block body 1 is cuboid, cushion block body 1 one side upper ends are provided with rectangular indentation 11, described rectangular indentation 11 the inners are provided with the first arc groove 2, described cushion block body 1 be positioned at the first arc groove 2 under position be provided with tipper 3, the setting that is inclined upwardly of described tipper 3 upper surfaces, and the angle forming between the upper surface of this tipper 3 and horizontal plane is acute angle, the lower surface of described tipper 3 and cushion block body 1 bottom surface be arranged in parallel.
For making structure setting of the present invention more reasonable, as preferably, the inner of tipper 3 is provided with the second arc groove 4 described in the present embodiment, after this second arc groove 4 is communicated with tipper 3, forms a complete draw-in groove.
The upper surface of described tipper 3 and the angle between horizontal plane are 30 °-75 °.Described the first arc groove 2 and the second arc groove 4 center of circle line parallels.The interior reinforcing bar 5 respectively of described the first arc groove 2 and the second arc groove 4, described reinforcing bar 5 matches with corresponding groove diameter.As preferably, the diameter of reinforcing bar 5 can be selected according to actual needs, and the diameter of general reinforcing bar 5 is more smaller than corresponding arc groove diameter.
Structure setting of the present invention is more reasonable; the first arc groove, tipper structure arrange rationally; the distance of cushion block body end face to the first arc groove equals thickness of protection tier and adds bar diameter; tipper and the second arc groove arrange rationally; the second arc groove to the distance of cushion block body bottom surface equals thickness of protection tier; cushion block body thickness equals slab thickness, at the bottom of can guaranteeing floor plate and the thickness of concrete cover of plate face, can effectively control thickness of concrete floor again.
Above-described embodiment is to specific descriptions of the present invention; only be used to further illustrate the present invention; can not be interpreted as limiting the scope of the present invention, within the technician of this area makes some nonessential improvement according to the content of foregoing invention to the present invention and adjusts and all to fall into protection scope of the present invention.
