Abstract

A steel corbel shear key structure for jacking and storey-adding is characterized in that embedded parts (2) are installed on the periphery of an original structural column (1), an upper corbel (3) is correspondingly arranged on the embedded part (2) on any side peripheral surface, three raised shear keys (4) are arranged on the back of the upper corbel (3), three jacks are arranged on the embedded part (2) connected with the upper corbel (3) corresponding to the shear keys (4), and the shear keys (4) are inserted into the corresponding jacks; the embedded part (2) connected with the upper bracket (3) is provided with a thickening layer. The bracket is convenient to install.

Description

Steel corbel shear key structure for jacking and storey adding

Technical Field

The utility model relates to a steel corbel, more specifically the steel corbel shear key structure that is used for jacking to add layer that says so.

Background

With the development of building industry, the concept of building storey-adding design in modern society has become a topic that is more generally concerned by industrial people. The house floor-adding has the advantages of no land occupation, less investment, quick effect, capability of quickly solving the problem of lacking houses and the like, and is particularly suitable for the national conditions of China, so that a great amount of old house floor-adding transformation is carried out in China in recent years, and good economic benefit and success are achieved.

At present, a building storey-adding reconstruction technology is gradually developed, and frame columns are jacked in the building storey-adding reconstruction technology. In the jacking and storey-adding process, a bracket structure and a jack are mostly adopted to realize the jacking process together. However, the corbel structure is usually fixed around each frame column by means of steel-bar-embedded steel; the bracket structure is fixed with the frame column and can not be lifted along with jacking and storey addition; and because the stroke of jack is limited, along with the increase of jacking height, the jack on fixed bracket must be constantly heightened, not only bring inconvenience to jacking construction operation, but also produce adverse effect to the stability of overall structure, be difficult to satisfy actual engineering demand.

Disclosure of Invention

An object of the utility model is to the above-mentioned problem that exists among the prior art, a steel corbel shear key structure for jacking increases layer is provided.

In order to achieve the above object, the technical solution of the present invention is: the utility model provides a steel bracket shear key structure for jacking increases layer, installs the built-in fitting around on original structure post, and arbitrary offside is global to correspond on the built-in fitting be provided with the bracket, last bracket back be provided with three bellied shear key, correspond the shear key on the built-in fitting of being connected with last bracket and be provided with three jack, the shear key is planted in corresponding jack.

And a thickening layer is arranged on the embedded part connected with the upper bracket.

The upper brackets on the peripheral surfaces of the opposite sides are connected through bolts.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses the shear key of well upper bracket back portion is planted in corresponding built-in fitting jack, and the shear key will undertake the effect of the shear force that resists the jacking and produce, simple to operate.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

Fig. 2 is a schematic view of the structure of the upper bracket of the utility model.

In the figure, an original structural column 1, an embedded part 2, an upper bracket 3 and a shear key 4.

Detailed Description

The invention is described in further detail below with reference to the following description of the drawings and the detailed description.

Referring to fig. 1 to 2, in the steel corbel shear key structure for jacking and layer-adding, embedded parts 2 are installed on the periphery of an original structural column 1, and an upper corbel 3 is correspondingly arranged on the embedded part 2 on any side of the peripheral surface of the original structural column; the back of the upper bracket 3 is provided with three raised shear keys 4, three jacks are arranged on the embedded part 2 connected with the upper bracket 3 corresponding to the shear keys 4, and the shear keys 4 are inserted in the corresponding jacks.

Referring to fig. 1 to 2, further, a thickening layer is arranged on the embedded part 2 connected with the upper bracket 3.

Referring to fig. 1 to 2, further, the upper brackets 3 on the opposite side surfaces are connected by bolts.

Referring to fig. 1 to 2, the steel corbel shear key structure is used for connecting an upper corbel 3 and an original structural column 1 in a jacking and storey-adding construction process. When the anti-shear key is used, before the upper bracket 3 is installed, the embedded parts 2 are installed on the periphery of the original structural column 1, and the embedded parts 2 on the two sides connected with the upper bracket 3 need to be thickened and three jacks of the anti-shear key are reserved. The back of the upper bracket 3 is provided with three raised shear keys 4, when the upper bracket 3 is installed, the shear keys 4 are inserted into the reserved jacks on the corresponding embedded parts 2, and in the jacking and storey-adding process, the shear keys 4 can bear the effect of resisting the shear force generated by jacking.

The foregoing is a more detailed description of the present invention, taken in conjunction with the specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific embodiments shown and described. To the utility model belongs to the technical field of ordinary technical personnel, do not deviate from the utility model discloses under the prerequisite of design, can also make a plurality of simple deductions or replacement, above-mentioned structure should all be regarded as belonging to the utility model discloses a protection scope.
