Abstract

The utility model relates to a cushion member for controlling reinforced concrete protective layer thickness, relating to the accessory member of the reinforced concrete reinforcing rib. The utility model is composed of an inner circular arc rib, a circular arc rib, radial ribs and a steel bar clip. The radial ribs are uniformly distributed on the inner circular arc rib and the circular arc rib, one end of each radial rib and the inner circular arc rib are connected into the integration, and the other end of each radial rib and the circular arc rib are connected into the integration in a crossing way. The steel bar clip is arranged in the inner circular arc rib, two handles of the steel bar clip and the steel bar clip are connected into the integration, and the two handles of the steel bar clip, two end parts of the inner circular arc rib and the circular arc rib are connected into the integration. The two handles of the steel bar clip form a horn-shaped opening. The cushion member has convenient operation, time saving, labour saving and convenient manufacture, and the utility model is favorable to the control of steel bar protective layer thickness, mould processing and precision assurance.

Description

The pad spare of control Minimum Concrete Protective Coating Thickness

The pad spare of control Minimum Concrete Protective Coating Thickness relates to a kind of steel concrete reinforcing rib accessory.

Minimum Concrete Protective Coating Thickness directly influences the building life-span, adopts at present mostly the concrete pad of band steel wire, is lashed to before formwork erection on the stirrup, and is time-consuming, take a lot of work, and influence the duration, is difficult to guarantee the accurate of protective layer thickness because of the concrete pad quality sometimes.

The purpose of this utility model is: a kind of pad spare design scheme of controlling Minimum Concrete Protective Coating Thickness is provided, and this pad part is easy to use, and the time and labour saving helps controlling the thickness of topping, and processing and fabricating is convenient.

The technical solution of the utility model is: the pad spare of control Minimum Concrete Protective Coating Thickness; interior circular arc muscle, circular arc muscle are arranged; radial rib and bar clamp constitute; radial rib is distributed in interior circular arc muscle, circular arc muscle; radial rib one end and interior circular arc muscle are connected as a single entity; the radial rib other end and circular arc muscle interconnection one; bar clamp places in the interior circular arc muscle; two handles of the bar clamp that is connected as a single entity with bar clamp are connected as a single entity with the both ends of interior circular arc muscle and circular arc muscle respectively; two handles of bar clamp constitute horn-like opening, are convenient to reinforcing bar and snap in from horn mouth.There is axial pad spare to stablize convex body on the interior circular arc muscle, is used to keep filling up part and is clipped in stablizing on the reinforcing bar.

It is one that the circular arc muscle also has external arc muscle and radial rib interconnection outward, and the two ends of external arc muscle are connected as a single entity with two handles of bar clamp respectively.

The pad spare of control Minimum Concrete Protective Coating Thickness is molded out of plastic shape.

Major advantage of the present utility model: easy to use, series of products can be made as required in the time and labour saving, and mould molding is easy to make, pad part dimensional standardization, the thickness of favourable control topping.

Below in conjunction with drawings and Examples the utility model is further specified:

Embodiment 1:

The pad spare (seeing Fig. 1, Fig. 2) of control Minimum Concrete Protective Coating Thickness; there are interior circular arc muscle 4a, circular arc muscle 4, radial rib 3 and bar clamp 1 to constitute; radial rib 3 is distributed on circular arc muscle 4a and the circular arc muscle 4; one end of radial rib 3 and interior circular arc muscle 4a are connected as a single entity; radial rib 3 other ends and circular arc muscle 4 intersect to link and are one; bar clamp 1 places in the interior circular arc muscle 4a; two handle 1a of the bar clamp that is connected as a single entity with bar clamp 1 are connected as a single entity with the both ends of interior circular arc muscle 4a and circular arc muscle 4 respectively, and two handle 1a of bar clamp constitute horn-like opening.The pad part is made with the mould of plastics moulding.

Embodiment 2:

With the difference of embodiment 1 be: on interior circular arc muscle 4a, also have axial pad spare to stablize convex body 2 (seeing Fig. 1, Fig. 2).

Embodiment 3:

With the difference of embodiment 1 or embodiment 2 be: also having external arc muscle 5 and radial rib 3 to intersect binding outside the circular arc muscle is one, the two ends of external arc muscle 5 respectively with two handle 1a of bar clamp be connected as a single entity (seeing Fig. 3, Fig. 4).
