Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a steel bar protection layer stirrup. Background Art

[0002] Existing steel bar protection layer limiting devices usually adopt forms such as plastic stirrups, stirrup bars, and cushion blocks. These methods only limit the protection layer for the top reinforcement or only for the bottom reinforcement, so as to avoid the problem that the steel bar is easily corroded due to too small a protection layer, or the effective height of the section is too small due to too large a protection layer. These methods have the following problems: Different limiting forms are used for the top and bottom reinforcements, which will increase the workload to a certain extent during construction; The bottom reinforcement often adopts the form of cushion blocks, and the steel bars are easy to slide off the cushion blocks, resulting in the problem of missing steel bar protection layers. Content of the Utility Model

[0003] The technical solution specifically adopted by the utility model for the above problems is: A steel bar protection layer stirrup, comprising: two cross-connected cross bars, and legs extending in the same direction are provided at both ends of each cross bar. An inclined bar extending inward is provided at the bottom end of each leg, and the inclined bar has elasticity.

[0004] Further improved, the length of the inclined bar is not less than half of the distance between the two legs arranged oppositely.

[0005] Further improved, the length of the inclined bar is greater than half of the distance between the two legs arranged oppositely.

[0006] Further improved, a connecting rod is provided between the two legs arranged oppositely.

[0007] Further improved, the two connecting rods are connected at the intersection point.

[0008] Further improved, the intersection point of the two cross bars is the lowest, and the cross bars gradually slope upward from the intersection point outward.

[0009] The beneficial effects of the utility model are:

[0010] The steel bar protection layer stirrup provided by the utility model can support and limit both the top reinforcement and the bottom reinforcement through one stirrup, which can avoid reducing the workload of installing the steel bar limiting device when laying the floor steel bars; At the same time, due to the inclined bar, it avoids the problem that the steel bars slide off the limiting device and cause the limitation to fail. Description of the Drawings

[0011] The following further illustrates the utility model in conjunction with the drawings and embodiments:

[0012] Figure 1 is the structural schematic diagram of the steel bar protection layer stirrup of the utility model;

[0013] Figure 2 This is a three-dimensional structural schematic diagram of the steel bar protection layer horse stool of the present utility model. Specific embodiments

[0014] Now, the present utility model will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0015] In the description of the utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the utility model.

[0016] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the utility model, "a plurality" means two or more, unless otherwise specifically defined.

[0017] In the utility model, unless otherwise clearly defined and limited, the terms "installation", "connection", "connection", "fixation", etc. should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the utility model can be understood according to specific situations.

[0018] Such as Figure 1 and Figure 2As shown in the figure, the utility model provides a steel bar protection layer stirrup, including: two cross-connected cross bars 1, which can be specifically connected by welding, or each cross bar 1 is composed of two short bars, and one end of the four short bars is fixedly connected in a cross shape. At both ends of each said cross bar 1, there are provided legs 2 extending in the same direction. Specifically, the legs 2 and the cross bar 1 can be bent from a metal pipe or metal rod. At the bottom end of each said leg 2, there is fixed an inclined bar 3 extending inwards, and the inclined bar 3 has elasticity. Specifically, one end of the inclined bar 3 is fixed at the bottom end of the leg or a position slightly above the bottom end by bolts or other fixing means, and the other end of the inclined bar 3 extends towards the opposite leg 2. And after the inclined bar 3 is deformed by an external force, it can restore its original shape when the external force is removed, so it can be made of a material with a certain elasticity, such as plastic or rubber, etc.

[0019] The bottom of this stirrup is open, and the opening is blocked by the elastic inclined bar 3. When in use, the steel bar can be pressed into this space (the space between the inclined bar 3 and the cross bar 1). When laying the surface reinforcement, the intersection of the horizontal and vertical steel bars of the surface reinforcement can be placed on the top of this stirrup (i.e., on the cross bar 1).

[0020] The steel bar protection layer stirrup provided by the utility model can support and limit both the surface reinforcement and the bottom reinforcement simultaneously through one stirrup, which can avoid reducing the workload of installing the steel bar limiting device when laying the floor steel bars; at the same time, due to the inclined bar, it avoids the steel bar slipping from the limiting device and causing the limit to fail.

[0021] In order to prevent the bottom reinforcement from slipping out between the inclined bars 3, a further improvement of this technical solution is that the length of the inclined bar 3 is not less than half of the distance between the two oppositely arranged legs 2. When in use, after the steel bar is pressed into the space between the inclined bar 3 and the cross bar 1, a self-closed structure is formed, and it is difficult for the bottom reinforcement to slip out.

[0022] In order to further improve the self-closed effect at the bottom of this stirrup, a further improvement of this technical solution is that the length of the inclined bar 3 is greater than half of the distance between the two oppositely arranged legs 2.

[0023] In order to prevent the legs 2 from deforming and causing the distance between the legs to change, resulting in the loss of the self-closed effect at the bottom of the stirrup, a further improvement of this technical solution is that a connecting rod 4 is provided between the two oppositely arranged legs 2. The connection method is preferably welding and fixed connection, so that the distance between the connected legs 2 will not change due to external forces.

[0024] A further improvement is that the two connecting rods 4 are connected at the intersection point. Specifically preferably, the connecting rod 4 can adopt four short bars, and the inner ends of the four short bars are welded and fixed together.

[0025] In order to prevent the surface reinforcement supported by the top of the stirrup from slipping off, a further improvement of this technical solution is that the intersection of the two cross bars 1 is the lowest, and the cross bars gradually slope upward outward from the intersection. That is to say, the center point at the top of this stirrup is the lowest. Therefore, the surface reinforcement supported by the top is not easy to slip off either.

[0026] Inspired by the above ideal embodiments based on the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
