Abstract

The utility model provides a universal chock test which is used for protecting construction steel reinforcement concrete protection layers) The function is to guarantee steel reinforcement in concrete not exposed. The technical characteristics are that the distance between steel reinforcement and a mould is controlled, which coincides with the thickness of a protection layer stated in the norm of the national compulsory construction. The outer appearance of the chock test is similar to a steering wheel of a steam boat wheelman (wheel rudder in abbreviation), an outer ring along the wheel rudder is provided with a clip opening, an inner ring is provided with a clamping flexible perpendicular radial stabilizing block which is held on a main reinforcement or a hoop reinforcement stably, and a same chock test can hold steel reinforcement with different diameters, and is not affected by casting vibration when in construction, the chock test can be used in different surfaces like beam, post, shear wall structure or bridge and can replace concrete or other chock tests. The employment is convenient, the working efficiency is improved, and the construction quality is guaranteed.

Description

The universal cushion block of reinforced concrete protective layer

In building iron concreting; no matter be beam, post, shear wall or the bridge engineering of basis and floor; for satisfying the requirement of topping; normally at the construction field (site) with cement mortar preformed pad piece or with steel scrap muscle and wooden unit; need with pricking the silk colligation on reinforcing bar; often because of pouring with when vibrating; cushion block is subjected to displacement, comes off; do not have the topping effect; serious the muscle phenomenon also can occur revealing, neither compliant requirement influences engineering structures bearing capacity and durability quality; time-consuming again, production efficiency is low.Regulation beam, post, shear wall or bridge engineering all should have the certain protection layer thickness in existing " reinforced concrete structural design specification ", " structure of reinforced concrete and the standards of acceptance ".How in construction, to guarantee the formation of topping; for addressing this problem; the utility model provides a kind of reinforced concrete protective layer plastics universal cushion block to the current techniques deficiency, and the reinforcing bar that it can satisfy basis and beam, post, shear wall or the bridge engineering different parts of floor is located and the formation of concrete cover.

The utlity model has following characteristic: 1, make full use of intensity, the elasticity of plastics, can be stuck on main muscle or the stirrup very easily; 2, may be stuck on any position and the direction, anyway rotate the equal protective layer thickness that can play a part to control; 3, be equipped with the reducing elastic card in the cushion block, be suitable for the reinforcing bar of card different-diameter; 4, ring was gone up and elastic card is provided with the stable piece of widening (5) (6) in pad was picked out, one snap into the position after, good stability; 5, inside and outside by eight symmetrical radiation tendons connections (2), per two muscle form bipod (3), play the supporting ﹠ stablizing effect jointly with outer toroid; But the cushion block letter of 6, selecting different-diameter for use covers the topping requirement of all different-thickness.7, production and use are all free from environmental pollution.

Figure one is the SD-X plan view, and X-is the topping numbering of different-diameter reinforcing bar and thickness.

Figure two is SD-Y plan views, and T-is the topping numbering of plane concrete different-diameter reinforcing bar and thickness.

Claims

1, a kind of universal cushion block of controlling Minimum Concrete Protective Coating Thickness; it is characterized in that: radially open a bayonet socket (1); inner and outer ring is connected by muscle (2); outer shroud circular arc (3); in be equipped with reducing elastic card (4); the reinforcing bar that can block different-diameter, on the interior ring and elastic card be provided with stable piece (5) (6), guarantee to be stuck in and not made firm by ramming by concrete casting to influence.The protective layer thickness of stipulating in distance between control reinforcing bar and the template and the building operations standard is identical.

2, a kind of cushion block of controlling Minimum Concrete Protective Coating Thickness; it is characterized in that: cushion block is cylindric (1); cushion block is established mutually vertical arc groove (2) (3) along cylinder both ends of the surface (4); groove footpath is identical with bar diameter, and the distance of notch arc surface and another side equals the protective layer thickness stipulated in the building operations standard.
