Problems solved by technology

However, for larger underpinning loads, four-sided wrapping underpinning nodes cannot be used due to the limitation of clearance requirements
At the same time, the four-sided wrapped underpinning joint still has the following problems: (1) It needs to pour concrete on site, which is easy to generate noise pollution; (2) It needs to be cut after use, resulting in construction waste; (3) The weight of the concrete component is large, increasing the lower part The cost of shifting track

Embodiment

[0052] Such as Figure 1~2 As shown in , a self-balancing steel underpinning device includes two sets of underpinning members arranged symmetrically on both sides of the underpinning column, and a jack arranged under the underpinning members, such as Figure 3-5 As shown, each group of underpinning members includes unequal flange I-shaped steel 1, the first connecting steel plate 2 arranged inside the unequal flange I-shaped steel 1, and the first connecting steel plate 2 arranged outside the unequal flange I-shaped steel 1 The second connecting steel plate 3, the pressure steel plate 4 welded to the upper flange 12 of the unequal flange I-shaped steel, and the stiffener 5 welded to the above-mentioned components. A connecting screw 7 is arranged on one side of the first connecting steel plate 2 , and a pull screw 6 is arranged between the second connecting steel plates 3 .

[0053] The principle of the present invention is: under the action of the underpinning load on the to...

Abstract

The invention relates to a self-balancing steel underpinning device. The self-balancing steel underpinning device comprises inequilateral flange I-shaped steel (1), first connecting steel plates (2) which are arranged on the inner side of the inequilateral flange I-shaped steel (1), second connecting steel plates (3) which are arranged on the outer side of the inequilateral flange I-shaped steel (1), compression steel plates (4) which are welded on upper flanges (12) of the inequilateral flange I-shaped steel, and stiffening ribs (5) which are welded among the components described above; connecting screws (7) are arranged on one sides of the first connecting steel plate (2); and a split screw (6) is arranged between the second connecting steel plates (3). Compared with the prior art, the self-balancing steel underpinning device is suitable for column underpinning with different loads, is convenient to construct, and is detachable and reusable.

Description

technical field [0001] The invention relates to an underpinning device, in particular to a self-balancing steel underpinning device. Background technique [0002] With the continuous development of modern society, people's requirements for the use and function of existing buildings are constantly changing, thus giving rise to practical engineering problems such as building jacking and displacement. Structural underpinning is an important link in building jacking and shifting engineering, which directly affects the success of building jacking and shifting. At present, the most widely used underpinning joint in our country is the four-sided wrapped column underpinning. The underpinning joint is to pour the underpinning beam around the underpinning column, and rely on the friction between the contact interface between the underpinning beam and the underpinning column to realize the force. The advantages of this underpinning method are small construction difficulty, simple comp...
