Abstract

A concrete-made split head with reinforced concrete protective layer comprises a split head body, and a notch disposed on the split head body and used for preventing reinforcing steel bar transversely shifting. The utility model is characterized in that a lateral deviation preventing mechanism is disposed on the concrete-made split head body. The utility model has the advantages of simple structure, high strength, convenient usage, low cost, and simple manufacturing method. The utility model can not only improve working efficiency and construction quality, but also can prevent potential safety hazard caused by expansion coefficient difference.

Description

Reinforced concrete protective layer concrete goods split heads

(1), technical field

The utility model relates to a kind of usefulness member under construction, and is particularly a kind of in the reinforced concrete construction process, keeps the split heads of the spacing between reinforcing bar and the template.

(2), background technology

Split heads claims Ma Dun again.In the work progress of steel concrete, in order to guarantee the spacing between reinforcing bar and the template, to prevent that reinforcing bar is exposed to outside the concrete, the existing practice be with the square or square spacer pad of a block length under reinforcing bar, make to keep corresponding gap between reinforcing bar and the template, placing of concrete is shaped then.This mode with the cushion block bearing bar exists following deficiency: the cushion block volume is bigger, heavy, installation is wasted time and energy, because cushion block upper support reinforcing bar place is smooth, supported reinforcing bar takes place mobile relatively easily under the influence of vibration force, to the gap between reinforcing bar and the template is disappeared, produce the exposure of reinforcing bar, have a strong impact on workmanship.Existing split heads is the plastic body that is the stool shape, plastic body is provided with the anti-traversing notch of reinforcing bar, though it has overcome above-mentioned deficiency, but it exists maximum problem to be: because this split heads is to make with plastic products, as everyone knows, plastic products are the cost height not only, intensity is low, and the coefficient of expansion is concrete about 3 times, therefore, and in the bigger post and beam that are imbedded in load-bearing of this clamp quantity, because of the coefficient of expansion than big-difference, reinforcing bar in clamp and the concrete is broken away from each other, produce the crack, malaria enters, the corrosion reinforcing bar exists serious potential safety hazard after for many years.

(3), summary of the invention

The purpose of this utility model just provides a kind of reinforced concrete protective layer concrete goods split heads simple in structure, that intensity is high, easy to use and with low cost; it not only can improve workmanship and efficiency of construction, and can also avoid the potential safety hazard that causes because of expansion coefficient difference.

The purpose of this utility model is to realize that by such technical scheme it includes the stool body, and the stool body is provided with the anti-traversing notch of reinforcing bar, it is characterized in that: the stool body made from concrete is provided with anti-lateral deviation mechanism.Because anti-lateral deviation mechanism has been arranged, avoided the stool side to overturning, improved the stability of bearing bar.Because of the stool body is to be become by the concrete system, its coefficient of expansion is consistent substantially with concrete, has also avoided being exposed to outside the concrete because of expanded by heating makes reinforcing bar, prevents that reinforcing bar from by the corrosion of moisture laden air, having eliminated the potential safety hazard that causes because of expansion coefficient difference.

Owing to adopted technique scheme, the utlity model has simple in structure, intensity is high, easy to use, with low cost and make advantages such as easy, it not only can be increased work efficiency, and improves workmanship, but also can avoid the potential safety hazard that causes because of expansion coefficient difference.

(5), the specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Shown in Fig. 1,2,3 or 4, the utility model includes stool body 1, and stool body 1 is provided with the anti-traversing notch 2 of reinforcing bar, it is characterized in that: the stool body made from concrete 1 is provided with anti-lateral deviation mechanism.Because anti-lateral deviation mechanism has been arranged, avoided the stool side to overturning, improved the stability of bearing bar.Because of the stool body is to be become by the concrete system, its coefficient of expansion is consistent substantially with concrete, has also avoided being exposed to outside the concrete because of expanded by heating makes reinforcing bar, prevents that reinforcing bar from by the corrosion of moisture laden air, having eliminated the potential safety hazard that causes because of expansion coefficient difference.

Shown in Fig. 1,2,3,4 or 5, anti-lateral deviation mechanism is provided with breach 7 below stool body 1, it is 75 degree～115 degree that these breach 7 places are provided with the folded angular range in plane that 3, two supporters 3 of two open each other supporters open the plane at place and stool body 1 place.Best angle is 90 degree.

As shown in Figure 1, supporter 3 can be reinforcing bar or steel wire.As shown in Figure 3, supporter 3 also can be a steel disc in the form of sheets, to strengthen the Area of bearing that supports, improves stability.As shown in Figure 2, supporter 3 can also be reinforcing bar or the steel wire that takes the shape of the letter U, and to strengthen Area of bearing, improves stability.

Shown in Fig. 4,5,, be provided with the fixture 8 of fixing two supporters 3 between two supporters 3 in order to strengthen the intensity between two supporters.

Shown in Fig. 4,6, stool body 1 surface is provided with is convenient to the coarse male and fomale(M﹠F) 6 that concrete is combined closely.

As shown in Figure 4, can be provided with reinforcing rib 4 in the stool body 1.Can also be provided with fibrous material 5 in the stool body 1.

As shown in Figure 1, for weight reduction, reduce cost, strengthen the binding ability of stool body and cement, stool body 1 side is provided with breach 9.
