Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to an adjustable-size shear-resistant groove mould for a steel structure. Background Art
[0002] The shear groove is a notch reserved in advance on the concrete foundation before the steel structure is installed. A shear key is welded on the bottom plate of the steel column using an I-beam or channel steel, and then the shear key is inserted into the shear groove. The primary function of the shear key is to resist the shear force at the bottom of the column and prevent slippage between the bottom plate of the column and the top surface of the foundation concrete. The anchor bolt is not allowed to resist shear because the gap between the anchor bolt and the bottom plate hole is large and cannot limit the displacement. Shear grooves appear in large numbers in steel structure buildings because the horizontal reaction force at the bottom of the column foot is not suitable for the column foot anchor bolt to bear. This horizontal reaction force is borne by the shear key. When pouring the concrete foundation, leave space for the shear key to be inserted in advance. The size of the shear groove should be moderate. It should not be too deep or too shallow. If it is too deep, it will collide with the steel bars of the short column, exposing the steel bars and affecting the structural safety of the building; if it is too shallow, the shear key of the bottom plate of the steel column cannot be fully inserted. At the same time, the plane position of the shear groove should not be too large, otherwise the thickness of the anchor bolt protective layer will be insufficient, which will have an adverse effect on the force of the bolt.
[0003] When placing shear grooves on site, workers usually use cut foam blocks to press into concrete. This method will cause a lot of material waste (the foam blocks are often damaged when taken out and cannot be used multiple times) and labor waste. Utility Model Content
