Abstract
The utility model relates to the technical field of constructional engineering, in particular to a cushion block of a concrete cover. The cushion block is frustum-shaped or prismatic table shaped, a cross-shaped groove is arranged at the top surface of the cushion block, multiple binding wires are arranged at the top of the cushion block, and multiple pouring basins are arranged on the sidewalls of the cushion block. The cushion block of the concrete cover, provided by the utility model, has the advantages of firm structure and convenience for installation, after concrete is poured on a frame structure of a building, the cushion block and the frame structure are tightly connected and are fused together, so that the quality of the whole building is improved.
Description
Technical field
The utility model relates to construction engineering technical field, particularly a kind of concrete protective layer pad.
Background technology
In reinforced concrete member, be not subjected to the oxidation of air and the impact of other factors in order to protect reinforcing bar, simultaneously, also in order to guarantee that reinforcing bar and concrete have good bonding, must guarantee that concrete cover to reinforcement reaches the thickness of designing requirement.Traditional way is to adopt cement slurry to make at the construction field (site) cushion block and insert iron wire or galvanized wire in the centre and then tie up on reinforcing bar, but often there are a lot of problems in this technique in practical operation, because field condition is relatively poor, the cushion block size thickness of making is very irregular, the thickness of topping in can not guaranteeing to construct, Shi Youlu muscle phenomenon occurs, and has influence on construction quality; In addition, cracked easily with the cushion block low strength that the cement mortar field fabrication goes out, can not guarantee well the thickness requirement of topping equally, thereby have influence on construction quality.
At present, normal operation plastic cushion in construction, relative spacer, plastic cushion is more durable, and by large-scale production, its quality is also relatively better.But, in existing various plastic cushions, also exist variety of issue to fail to solve.Divide from shape, mainly be divided into claw type and platform shape in the cushion block, the problem of claw type cushion block is that it is lightweight, structure is unstable, and the surface of platform shape cushion block is more smooth in the prior art, and behind the fluid concrete, it can not closely link to each other with frame construction, more be difficult for combining together, thereby can affect structural quality, in addition, the perforate on the cushion block body of existing some cushion block, be used for being fixed on main reinforcement or secondary reinforcing bar, but because the problem that exists lateral displacement and circumferencial direction to rotate still needs with binding it to be banded on the reinforcing bar, could really fix, reach in addition tied silk be banded in the operation cumbersome, increased difficulty of construction.
The utility model content
The purpose of this utility model is to provide a kind of stabilized structure, concrete protective layer pad quick for installation.
The purpose of this utility model is achieved through the following channels: a kind of concrete protective layer pad, cushion block are frustum or prism-frustum-shaped, and the cushion block end face is provided with cross groove, and the cushion block top is provided with some bindings, and the cushion block sidewall is provided with some pouring basins.
As the further optimization of scheme, described pouring basin is crisscross distribution.
As the further optimization of scheme, the bottom land of described cross groove is arc.
As the further optimization of scheme, the quantity of described binding is even numbers, is symmetric at the top of cushion block.
The utility model concrete protective layer pad stabilized structure, easy for installation, behind building frame structure fluid concrete, it can closely link to each other with frame construction, combines together, thereby can improve the quality of whole building.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Among the figure, cushion block 1, cross groove 2, pouring basin 3, binding 4.
The specific embodiment
As shown in Figure 1; the utility model concrete protective layer pad; cushion block 1 is frustum or prism-frustum-shaped; cushion block 1 end face is provided with the cross groove 2 that bottom land is arc; cushion block 1 top is provided with some bindings 4; the quantity of binding 4 is even numbers, is symmetric at the top of cushion block 1, and cushion block 1 sidewall is provided with some the pouring basins 3 that are crisscross distribution.
During use, reinforced frame is placed on the cross groove 2, with binding 4 cushion block and reinforced frame are tied up again fixing, last fluid concrete, concrete is injected into the pouring basin 3 of cushion block 1 sidewall, can by the concrete in these grooves cushion block and frame construction be combined together very soon.
