Embodiment 1

[0030] Such as Figure 1~4 Shown: a high-performance pre-embedded steel anchor plate, including a toothed T-shaped plate 1 and anchor bars 2, the web of the toothed T-shaped plate 1 is tooth-shaped with equal width, and the gap between the two teeth can penetrate The width of the single tooth is smaller than the net spacing of the stirrups, and the anchor bar 2 is welded to the flanges on both sides of the web of the toothed T-shaped plate 1; the toothed T-shaped plate 1 adopts a rectangular cut 3 The web of the I-shaped steel is cut in dislocation to ensure that the tooth web 1-1 of the toothed T-shaped plate 1 and the flange 1-2 are integrated to avoid welding, and the toothed web 1-1 of the toothed T-shaped plate 1- The end of 1 is welded vertically to the lower anchor plate 1-1-1.

Embodiment 2

[0032] Such as Figure 5 As shown: this embodiment is the same as the rest of embodiment 1, except that the end of the tooth web 1-1 is bent to form an L-shaped anchor head 1-1-2.

Embodiment 3

[0034] Such as Image 6 As shown: this embodiment is the same as the rest of embodiment 1, the difference is that the tooth webs 1-1 of the toothed T-shaped plate 1 are not equal in width, and the cutting seam 3 is a trapezoidal line, which is wide at the top and narrow at the bottom. cross-sectional form.

Abstract

The invention discloses a high performance pre-embedded steel anchor plate. The high performance pre-embedded steel anchor plate comprises toothed T-shaped plates and anchor bars. Webs of the toothed T-shaped plates are toothed. A hooping is passed through the gap between every two teeth. The width of one single tooth is smaller than the net spacing of the hooping. The anchor bars are welded to two side flanges of the webs of the toothed T-shaped plates. each toothed T-shaped plate is formed by cutting a web of I-shaped steel in a staggered mode, and the toothed webs of the toothed T-shaped plates and the flanges are formed in a whole. Lower anchor plates are welded to the ends of the T-shaped plates or the protruding plates are bent to form L-shaped anchor plates, so that the anchoring capacity in concrete is enhanced. The protruding plates of the T-shaped plates correspond to joint plates in position and force can be more effectively transmitted; the "integral molding" mode of staggered cutting is mature in process, materials are saved, the cost is reduced, welding can be avoided and the performance is improved; the space of cutting can be flexibly adjusted according to the location of the concrete component hooping to reduce the difficulty of construction.

Description

technical field [0001] The invention belongs to the field of civil engineering and relates to a high-performance pre-embedded steel anchor plate for connecting a reinforced concrete frame and a steel support. Background technique [0002] Reinforced concrete frame structure is a load-bearing system composed of frame beams and frame columns rigidly connected. It has the advantages of flexible space layout and light weight. It is suitable for multi-storey and some high-rise buildings in areas with low seismic fortification intensity. However, it is a flexible structure with low lateral stiffness. With the increase of the seismic fortification intensity of the area and the increase of building height, the horizontal action represented by wind load and earthquake action increases significantly, and the lateral deformation of reinforced concrete frame increases. Large, which in turn leads to structural damage or even collapse, seriously threatening people's lives. [0003] Setti...
