Description
Technical field
The present invention relates to a kind of building product, especially a kind of spigot-type circle protective layer cushion block.
Background technology
In architectural engineering, the situation of frequent casting concrete in need, such as reinforced concrete protective layer, and reinforcing bar mixes
For the thickness relationship of solidifying protective soil layer to performances such as the bearing capacities, durability, fire prevention of structure, protective layer is too thin to easily infiltrate into moist gas
Body and water, blocked up then easy generation crack, these may all make steel bar corrosion and expand, so that concrete wrecks, shadow
Ring using safe with structure.Being wire-tie due to casting should maintain a certain distance between exterior sheathing, so generally requiring in reinforcing bar
With exterior sheathing every a distance, a cushion block is tied up therebetween, can be separated by a distance with exterior sheathing by reinforcing bar.
It is not any with reinforcing bar and the cushion block in concrete cover is typically directly padded on reinforcing bar lower part in the prior art
Fixed, when concrete cast is shaken, reinforcing bar and cushion block fixation are insecure, and reinforcing bar is easily separated from cushion block, is subjected to displacement, shadow
Ring construction quality.
Also some will be connected between cushion block and reinforcing bar by connecting rope, but trivial operations, increase labor strength.
The content of the invention
The technical assignment of the present invention is to provide a kind of spigot-type circle protective layer pad for above-mentioned deficiency of the prior art
Block, a kind of spigot-type circle protective layer cushion block have with bar connecting it is firm, prevent reinforcing bar depart from cushion block be subjected to displacement, avoid
Influence construction quality, it is easy to operate, reduce labor strength the characteristics of.
The technical solution adopted by the present invention to solve the technical problems is：It includes upper cushion block body and underlay block body,
The upper cushion block body and the setting symmetrical above and below of underlay block body, and be respectively semicircle, under the upper cushion block body
The upper middle position of portion centre position and underlay block body is respectively arranged with reinforcing bar accommodating cavity, and two reinforcing bar accommodating cavities surround one
Circular cavity, circular cavity are engaged with bar diameter, are respectively arranged with left and right sides of the lower part of the upper padding plate body
Slot and upper inserted block, the top left and right sides of the lower bolster body is respectively arranged with lower inserted block and lower slot, under described
Inserted block is engaged with upper slot, and lower slot is engaged with upper inserted block, and the upper slot and lower slot are respectively wedge groove.
Circular through hole is respectively arranged with the upper cushion block body and underlay block body.
Circular through hole and the intrinsic circular through hole of lower cushion block in the upper cushion block body include three, and edge respectively
Circumferencial direction is uniformly arranged.
The upper cushion block body and the thickness of underlay block body are 10mm.
The upper slot and the width of lower slot are respectively 5-10mm.
Distance at the top of the top of the upper cushion block body and the reinforcing bar accommodating cavity of its underpart is 15-50mm.
The distance of the bottom of the underlay block body and the reinforcing bar accommodating cavity bottom of its upper part is 15-50mm.
The upper padding plate body and lower bolster body is respectively that plastics are made.
Compared to the prior art a kind of spigot-type circle protective layer cushion block of the present invention, has beneficial effect following prominent
Fruit：Reinforcing bar between upper cushion block body and underlay block body, upper cushion block body and underlay block body by the slot of wedge shape and
Inserted block is engaged grafting, prevent cushion block body along above and below underlay block body, left and right directions is moved out, and then avoids inserting in
Reinforcing bar between cushion block body and underlay block body moves up and down, firm with bar connecting, prevents reinforcing bar from departing from cushion block hair
The features such as raw displacement, avoids influencing construction quality, easy to operate, reduction labor strength.

Embodiment
A kind of spigot-type circle protective layer cushion block of the present invention is made in detail below with reference to Figure of description 1 to attached drawing 5
Explanation.
A kind of spigot-type circle protective layer cushion block of the present invention, its structure include upper cushion block body 1 and underlay block body 2,
2 setting symmetrical above and below of upper cushion block body 1 and underlay block body, and be respectively semicircle, the upper cushion block body 1
Lower middle position and the upper middle position of underlay block body 2 are respectively arranged with reinforcing bar accommodating cavity 3, two reinforcing bar accommodating cavities 3
A circular cavity is surrounded, circular cavity is engaged with bar diameter, is set respectively at left and right sides of the lower part of the upper padding plate body 1
Slot 4 and upper inserted block 5 are equipped with, lower inserted block 6 and lower slot are respectively arranged with left and right sides of the top of the lower bolster body 2
7, the lower inserted block 6 is engaged with upper slot 4, and lower slot 7 is engaged with upper inserted block 5, the upper slot 4 and lower slot 7
Respectively wedge groove.Prevent cushion block body 1 along underlay block body about 2, left and right directions is moved out, and then avoids inserting in
Reinforcing bar between cushion block body 1 and underlay block body 2 moves up and down.
Circular through hole 8 is respectively arranged with the upper cushion block body 1 and underlay block body 2.Make cast in circular through hole 8
Concrete, the connection area of cushion block body, underlay block body and concrete in increase, strengthens cushion block in concrete cover
Use intensity.
