Abstract
A concrete product cross trough-shaped split head used by the reinforced concrete protective layer comprises a split head body (2) which has a flat top or has a side shifting proof trough (1) on the top, characterized in that the bottom of the split head body (2) made by the concrete is equipped with a cross trough (3) which is sleeved with a cross reinforcing steel bar to form the mutual restriction, in order to limit the movement of the split head body and can make the two adjacent reinforcing steel bars able to always keep the original space no matter what shock is forced, and the operation is quite easy and convenient. The utility model has the advantages of simple structure, high strength, convenient utilizing, low cost, easy manufacturing and the like, and not only can advance the operating efficiency and the engineering quality but also can remarkably reduce the insecurity hidden trouble induced by the difference of the expansion coefficient.
Description
(1), technical field
The utility model relates to a kind of usefulness member under construction, and is particularly a kind of in cast-in-site roof cross reinforced concrete construction process, keeps the split heads of the spacing between cross reinforcing bar and the reinforcing bar.
(2), background technology
Split heads is in the work progress of steel concrete, for the even branch up and down between the cross reinforcing bar that guarantees cast-in-site roof and the reinforcing bar, to improve reinforcing bar and concrete pre-stress, the existing practice: be up and down between two reinforcing bars with cuboid or square bodily form cement mortar cushion block pad, make and keep corresponding spacing, placing of concrete solidification forming then between cross reinforcing bar and the reinforcing bar.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 and reinforcing bar contact position are smooth, usually easily under reinforcing bar vibration and concrete expansion, relatively move between cushion block and the reinforcing bar, even cushion block comes off, and it is not excessive making the spacing between reinforcing bar and the reinforcing bar, is exactly too small, can not satisfy construction requirement, have a strong impact on workmanship.The existing split heads that also has a kind of plastics to make, its top is provided with the anti-notch that moves of cross, though it has overcome above-mentioned deficiency, but it exists maximum problem to be: because it is made of plastic, its coefficient of expansion is concrete 3-4 times, therefore, it is the cost height not only, intensity is low, easily aging, and it is buried in the cast-in-site roof of load-bearing, because of the coefficient of expansion than big-difference, reinforcing bar in plastics split heads and the concrete is broken away from each other, produce the crack, malaria enters, the corrosion reinforcing bar, will damage the structure in house for many years, cause serious hidden danger.
(3), summary of the invention
The purpose of this utility model just provides a kind of reinforced concrete protective layer simple in structure, that intensity is high, easy to use and with low cost concrete goods cross flute profile split heads; it not only can improve workmanship and efficiency of construction, and can also reduce the hidden danger that causes because of expansion coefficient difference significantly.
The purpose of this utility model is to realize by such technical scheme, and it includes the top is the plane or has an anti-stool body that moves groove, and it is characterized in that: the stool body bottom made from concrete is provided with cross recess.Because stool body lower curtate of the present utility model is provided with cross recess, with cross reinforcing bar fit, form constraint mutually, no matter be subjected to what vibration, can not produce the stool body moves, all can make adjacent two reinforcing bars can remain the spacing that should have, and operation is very easy, thereby improves workmanship and efficiency of construction.Because the stool body is that concrete is made, its coefficient of expansion is consistent substantially with concrete, thereby reduces the hidden danger that causes because of expansion coefficient difference significantly.
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, improve workmanship, but also can reduce the hidden danger that causes because of expansion coefficient difference significantly.
(4), description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is the structural representation of first kind of embodiment of the utility model;
Fig. 2 is the structural representation of second kind of embodiment of the utility model;
Fig. 3 is the structural representation of the third embodiment of the utility model;
Fig. 4 is the structural representation of the 4th kind of embodiment of the utility model;
Fig. 5 is the user mode reference diagram of Fig. 1.
Among the figure: 1. anti-sidesway groove; 2. stool body; 3. cross recess; 4. metallic fiber; 5. fibrous material.
(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, it is plane or the stool body 2 that has an anti-sidesway groove 1 that the utility model includes the top, it is characterized in that: stool body 2 bottoms made from concrete are provided with cross recess 3.Because stool body of the present utility model bottom is provided with cross recess, with cross reinforcing bar fit, form constraint mutually, limited moving of stool body, no matter be subjected to what vibration, all can make adjacent two reinforcing bars can remain the spacing that should have, and operation is very easy, thereby improves workmanship and efficiency of construction.Because the stool body is that concrete is made, its coefficient of expansion is consistent substantially with concrete, thereby reduces the hidden danger that causes because of expansion coefficient difference significantly.
As shown in Figure 1, in order to strengthen the intensity of stool body, stool body 2 inside can be provided with metallic fiber 4.As shown in Figure 2, stool body 2 inside also can be provided with fibrous material 5.
As shown in Figure 1, stool body 2 outer shape can the side's of being platform shape.As shown in Figure 2, stool body 2 outer shape can be cylindrical.As shown in Figure 3, stool body 2 outer shape also can be cube, and as shown in Figure 4, stool body 2 outer shape can also be cuboid.
