Abstract
The utility model discloses a high-strength reinforcing steel bar cushion block used for reinforced concrete, which comprises an approximately cuboid cushion block body (1); the upper surface of the cushion block body (1) is recessed to form a clamping groove (2); two ends of the clamping groove (2) are aligned to one group of parallel side surfaces of the cushion block body (1); the width of the clamping groove (2) is equal to a distance between the other group of parallel side surfaces of the cushion block body (1); the bottom surface of the cushion block body (1) is provided with three approximately cuboid support strips (3); the bottoms of the support strips (3) are arranged into zigzag shapes; the support strips (3) are parallel to one another and are distributed on the bottom surface of the cushion block body (1) equidistantly. Through the adoption of the structure, the high-strength reinforcing steel bar cushion block can ensure that a reinforcing steel bar is difficult to displace, guarantee a constant distance between the reinforcing steel bar and an external template, improve the strength of the cushion block at the same time and ensure the attractive appearance and the reliability of the cushion block.
Description
Technical field
The utility model relates to a kind of cushion block, specifically is a kind of high strength cast iron cushion block that is used for steel concrete.
Background technology
In present construction work, the situation that needs concreting is often arranged, such as reinforced concrete protective layer.And the thickness relationship of reinforced concrete protective layer is to performances such as the bearing capacity of structure, durability, fire prevention; Too thin easy infiltration wet gas of topping and water; The blocked up crack that then is easy to generate; These all possibly make corrosion of steel bar and expand, thereby concrete is wrecked, and influence is used and structural safety.Therefore, when concreting,, often need lay a cushion block at a certain distance at reinforcing bar and outer template in order to make the certain distance of maintenance between reinforcing bar and the outer template.At present, though generally adopt cushion block simple in structure, needed material is many when pinioning, even and tied at that time, also be easy to be shifted, cause between reinforcing bar and the outer template to keep constant distance.Simultaneously, in order not influence the concrete aesthetic after the moulding, cushion block all is designed and reduces as much as possible and the contacting of outer template, but does not so often reach certain intensity again, influences the support reliability of cushion block.
The utility model content
The utility model provides a kind of high strength cast iron cushion block that is used for steel concrete; Solved cushion block binding trouble in the past, be easy to be shifted; Cause between reinforcing bar and the outer template to keep constant distance, simultaneously, can not accomplish the aesthetic property of cushion block and the problem that reliability is taken into account.
The utility model is that the technical solution problem mainly realizes through following technical scheme: a kind of high strength cast iron cushion block that is used for steel concrete; Comprise that global shape is the cushion block body of cuboid; The upper surface indent of said cushion block body forms draw-in groove, and the two ends of said draw-in groove flush with wherein one group of parallel side of cushion block body, and the width of draw-in groove is equal with distance between the other one group of parallel side of cushion block body; The support bar that it is cuboid that the bottom surface of said cushion block body is provided with 3 global shapes; Zigzag is arranged in the bottom of said support bar, be parallel to each other between the support bar, and 3 support bars equidistantly is distributed on the bottom surface of cushion block body.
The two ends of said draw-in groove are positioned at same level height.
The degree of depth of said draw-in groove be the cushion block body height 1/6 ~ 1/3.
The length of said support bar and the equal in length of draw-in groove.
Said support bar is parallel to each other with wherein one group of parallel side of cushion block body.
The utility model compared with prior art has the following advantages and beneficial effect:
(1) the utility model is stuck in reinforcing bar on the cushion block through the mode that draw-in groove is set on the cushion block body, need not colligation, and make reinforcing bar be not easy to be shifted, be not easy to come off supporting & stablizing.
(2) the utility model is provided with 3 support bars in the bottom of cushion block body, and 3 support bars equidistantly are distributed on the bottom surface of cushion block body, have shared the load-bearing of whole cushion block effectively, have improved the intensity of cushion block, make support more reliable.
(3) zigzag is arranged in the bottom of the support bar of the utility model, has reduced contacting of cushion block and outer template, make take off outer template after, reduced cushion block effectively and exposed the part outside concrete, and then reduced the cushion block influence attractive in appearance concrete.

The specific embodiment
Below in conjunction with embodiment the utility model is done further to specify, but the embodiment of the utility model is not limited thereto.
Embodiment:
Like Fig. 1-shown in Figure 4; The utility model comprises that global shape is the cushion block body 1 of cuboid; The upper surface indent of cushion block body 1 forms draw-in groove 2; The two ends of draw-in groove 2 flush with wherein one group of parallel side of cushion block body 1, and the distance between the width of draw-in groove 2 and the cushion block body 1 other one group of parallel side equates.
The support bar 3 that it is cuboid that the bottom surface of the cushion block body 1 of present embodiment is provided with 3 global shapes, zigzag is arranged in the bottom of support bar 3, be parallel to each other between the support bar 3, and 3 support bars 3 equidistantly is distributed on the bottom surface of cushion block body 1.
The two ends of the draw-in groove 2 of present embodiment are positioned at same level height, the degree of depth of draw-in groove 2 be cushion block body 1 height 1/6 ~ 1/3.
The length of the support bar 3 of present embodiment and the equal in length of draw-in groove 2, and support bar 3 is parallel to each other with wherein one group of parallel side of cushion block body 1.
The operating principle of the utility model is: the utility model at first lies in cushion block body 1 on the outer template in use, and support bar 3 contacts with outer template, then reinforcing bar is stuck in the draw-in groove 2, can make the certain distance of maintenance between reinforcing bar and the outer template.
As stated, then can realize the utility model well.
