The utility model has the advantages of simple structure, convenient operation, low cost, easy manufacture, etc., and can not only increase the work efficiency and the engineering quality, but also avoid the safety hidden trouble caused by the differences of the swell factor.

Description

Reinforced concrete protective layer concrete goods locator card

(1), affiliated technical field

The utility model relates to a kind of with the member in the building, and is particularly a kind of in the reinforced concrete construction process, protects the cushion block of the spacing between special steel muscle and the template.

(2), technical background

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 is that the square or square spacer of a block length is banded on the stirrup with iron wire, make to keep corresponding gap between reinforcing bar and the template, placing of concrete is shaped then.This mode of tying up with cushion block exists following deficiency: artificial once to tie up not fastening spacer loosening, or easily rotate at the lower cushion block that influences 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, and the work efficiency of tying up spacer with iron wire by hand is very low.Disclose the utility model patent that a kind of name is called " plastic clip in a kind of construction work " in CN2348044Y, its feature is the clamp that the two ends of a unsealed garden ring-type respectively have a pin to link to each other, and its appearance has coarse horizontal stripe and decorative pattern.Though it is low that this patent has a cost, fabrication and installation are simple, fast, reliable advantage, improved operating efficiency, controlled the gap between reinforcing bar and the template, overcome above-mentioned deficiency, but it exists maximum problem to be: the clamp of its garden ring-type is made with plastic products, as everyone knows, plastic products are the cost height not only, 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, exist 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 simple in structure, easy to use and with low cost with concrete goods locator card, and it not only can improve workmanship, and can also avoid the potential safety hazard that causes because of expansion coefficient difference.

The purpose of this utility model is to realize by such technical scheme, and it is that concrete goods card body is provided with a therefrom outer gradually open form notch of mind-set, and gradually the open form notch is provided with elasticity from card device.

The utility model is to use like this: the gradually open form notch on the concrete goods card body directly is enclosed within on the reinforcing bar, and elasticity is blocked reinforcing bar automatically from card device, and reinforcing bar can not be deviate from from open form notch gradually.Because concrete goods card body kayser is on reinforcing bar, no matter how concrete goods card body rotates, and it all can keep the spacing between reinforcing bar and the template all the time, behind the placing of concrete, has prevented exposing of reinforcing bar.Because the coefficient of expansion and the concrete of concrete goods card body are identical, therefore, have avoided the potential safety hazard that causes because of expansion coefficient difference.And the utility model installation is very convenient, has not only improved workmanship, has also improved operating efficiency.Gradually open form notch of the present utility model is meant the therefrom outer notch that increases gradually of mind-set, and it can be a V-arrangement, also can be the shaped form of arcuation, can also be zigzag.

Owing to adopted technique scheme, the utlity model has simple in structure, 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.

Among the figure: 1. concrete goods card body; 2. open form notch gradually; 3. elastic wire or steel disc; 4. blind hole or hole; 5. coarse male and fomale(M﹠F); 6. reinforcing rib.

(5), the specific embodiment

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

As shown in Figure 1, it is that concrete goods card body 1 is provided with a therefrom outer gradually open form notch 2 of mind-set for the utility model, and gradually open form notch 2 is provided with elasticity from card device.

Shown in Fig. 1,5, the utility model is to use like this: the gradually open form notch 2 on the concrete goods card body 1 directly is enclosed within on the reinforcing bar, and elasticity is blocked reinforcing bar automatically from card device, and reinforcing bar can not be deviate from from open form notch 2 gradually.Because concrete goods card body 1 kayser is on reinforcing bar, no matter how concrete goods card body 1 rotates, and it all can keep the spacing between reinforcing bar and the template all the time, behind the placing of concrete, has prevented exposing of reinforcing bar.Because the coefficient of expansion and the concrete of concrete goods card body 1 are identical, therefore, have avoided the potential safety hazard that causes because of expansion coefficient difference.And the utility model installation is very convenient, has not only improved workmanship, has also improved operating efficiency.

Shown in Fig. 1,2 or 3, elasticity is to be made by elastic wire or steel disc 3 from card device, and the termination that is arranged on the both sides of open form notch 2 gradually and elastic wire that corresponds to each other or steel disc 3 toward each other.This elasticity is to lock reinforcing bar like this from card device, in the process that open form notch 2 is gradually put toward reinforcing bar, allow reinforcing bar overcome the elastic force of elastic wire or steel disc 3, make reinforcing bar be positioned at the gradually bottom of open form notch 2, because elastic wire or steel disc 3 are bent song, and after the resilience, the distance between the termination of corresponding two elastic wires or steel disc 3 is less than the diameter of reinforcing bar, make reinforcing bar can not deviate from gradually open form notch 2, thereby reinforcing bar is automatically locked.

Shown in Fig. 1,2 or 3, under the condition that size allows, gradually the elastic wire on open form notch 2 every limits or the number of steel disc 3 can be more than 2 or 2.

As shown in Figure 1, the shape of concrete goods card body 1 can be the disk shape.As shown in Figure 2, the shape of concrete goods card body 1 also can the side's of being sheet.As shown in Figure 3, Figure 4, the shape of concrete goods card body 1 can also be spherical.

Shown in Fig. 1,2 or 3, be combined into firm one for the ease of concrete and the concrete goods that water, concrete goods card body 1 is provided with and makes the blind hole or the hole 4 of combining closely in concrete.

As shown in Figure 1, be combined into firm one for the ease of concrete and the concrete goods that water, concrete goods card body 1 surface is arranged for ease of the coarse male and fomale(M﹠F) 5 that concrete is combined closely.

As shown in Figure 1, in order to strengthen intensity of the present utility model, be provided with reinforcing rib 6 in the concrete goods card body 1.
