Abstract
The utility model discloses a hairbrush type shear key below a steel column base. A plurality of reinforcing steel bars or anchor bolts are uniformly distributed on the bottom plate of the steel column base; the reinforcing steel bars or the anchor bolts are hairbrush-shaped, and are anchored in concrete; the diameters of the reinforcing steel bars or anchor bolts are different. According to the utility model, short and thick reinforcing steel bars are arranged to be hairbrush-shaped, so that the reinforcing steel bars are conveniently inserted into the reinforcing cage of a concrete member, therefore, the shear key is reasonably arranged to avoid the construction difficulty of the shear key.
Description
Technical field
The utility model relates to building structure, steel work.
Background technology
In steel work suspension column design now, when surpassing between suspension column and concrete frictional force, establishes shearing shear key.Regulation and stipulation need arrange pedestal shear key when suspension column shearing is greater than the suspension column axle power of 0.4 times, according to the actual conditions of suspension column shearing, arranges.It uses thicker channel-section steel vertical welding conventionally on the horizontal steel plate of suspension column bottom surface, and is embedded in formation in concrete basis.
The primary effect of shear key is opposing shearing, and restriction suspension column is subjected to displacement in certain direction, and method to set up can be spent shape steel plates, channel-section steel, I steel etc. with ten sons.When reinforcement ratio in the concrete component under post is closeer, adopt traditional shear key can not reliably construct, sometimes even cannot construct, under post, shear key is difficult to be inserted in the steel mesh reinforcement of concrete component.
Utility model content
The utility model main purpose is to provide the Brush type shear key of a kind of steel column underfooting, by adopting short and thick reinforcement placement to become hairbrush shape, inserts easily in the reinforcing cage of concrete component, thereby reasonably arranges shear key, avoids the constructional difficulties of shear key.The stressed friction shear resisting theory that can adopt of this kind of Brush type shear key is carried out force analysis, carries out Design of Bearing Capacity.
To achieve these goals, the utility model adopts following technical scheme.
A Brush type shear key for steel column underfooting carries out matrix ranks according to a determining deviation by some bar dowels or crab-bolt and is evenly arranged on suspension column base plate, and its length is carried out effective anchoring in concrete according to certain anchorage length.
The reinforcing bar or the crab-bolt that are hairbrush shape are called as hairbrush shear key, are effectively welded to connect with base plate.The shearing of hairbrush shear key and resistance to plucking are all effectively reliable.The bar diameter of Brush type shear key can be different, can arrange according to the size of the reinforced hole of concrete beam, but should try one's best evenly.
The beneficial effects of the utility model: by adopting short and thick reinforcement placement to become hairbrush shape, insert easily in the reinforcing cage of concrete component, thereby reasonably arrange shear key, avoid the constructional difficulties of shear key.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1, bar dowel; 2, suspension column base plate.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.
In the utility model, the suspension column base plate 2 of bar dowel 1 and steel column is effectively connected, and as shown above, hairbrush shear key is evenly arranged in the middle of base plate.
Brush type shear key suspension column in the utility model can also can on-the-spotly carry out scene processing according to concrete spacing in factory process moulding, and easy construction is safe and reliable.Then lifting, positions.
Although above-mentioned, by reference to the accompanying drawings the specific embodiment of the present utility model is described; but the not restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
Claims (1)
1. a Brush type shear key for steel column underfooting, is characterized in that, some reinforcing bars or crab-bolt are evenly arranged on suspension column base plate, and described reinforcing bar or crab-bolt are hairbrush shape, the anchoring in concrete of described reinforcing bar or crab-bolt; The diameter of described reinforcing bar or crab-bolt is different.
