Abstract

A lifting steel bracket for jacking and storey-adding comprises an upper bracket (1) and a lower bracket (2), wherein a jack (8) is arranged between the upper bracket (1) and the lower bracket (2), the upper bracket (1) is fixedly connected with a concrete filled steel tubular column (3), and the lower bracket (2) is movably connected with a steel slide way (4) on the frame column (3); t-shaped steel frames (5) are arranged at four corners of a steel slide way (4) on the frame column (3), clamping grooves (6) are formed in the back of the lower bracket (2) corresponding to the T-shaped steel frames (5), and the corresponding clamping grooves (6) are connected with the T-shaped steel frames (5) in a clamping mode. The lower bracket (2) can be lifted synchronously with the building along with the jacking of the building, so that the stroke of the jack (8) needing to be lifted is greatly shortened; and this lower bracket (2) can be dismantled, can guarantee bracket simple to operate when also can practice thrift the cost that the bar planting is connected.

Description

Lifting steel bracket for jacking and storey-adding

Technical Field

The utility model relates to a steel corbel, more specifically the lifting steel corbel 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

The utility model aims to provide a liftable steel bracket that is used for jacking to increase layer to defects such as current bracket structure is fixed with the frame post, can not go up and down.

In order to achieve the above object, the technical solution of the present invention is: the utility model provides a liftable steel bracket for jacking increases layer, includes bracket and lower bracket, goes up the bracket and is provided with the jack down between the bracket, last bracket and steel core concrete column fixed connection, lower bracket and the steel slide swing joint on the frame post.

T-shaped steel frames are arranged at four corners of the steel slide ways on the frame columns, clamping grooves are formed in the back of the lower bracket corresponding to the T-shaped steel frames, and the corresponding clamping grooves are connected with the T-shaped steel frames in a clamped mode.

The upper bracket is connected with the frame column through a through screw.

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

the upper bracket of the liftable steel bracket of the utility model is fixedly connected with the frame column and can be integrally jacked as a part of the upper structure; the lower bracket is movably connected with the steel slideway through the clamping groove and the bolt, so that the lower bracket can be synchronously lifted along with the lifting of the building, and the stroke of the jack needing to be lifted is greatly shortened; and this lower bracket can be dismantled, can guarantee bracket simple to operate when also can practice thrift the cost of planting the muscle connection.

Fig. 3 is a schematic view of the structure of the middle and lower corbels of the present invention.

Fig. 4 is a sectional view B-B of fig. 3.

In the figure, an upper bracket 1, a lower bracket 2, a frame column 3, a steel slideway 4, a T-shaped steel frame 5, a clamping groove 6, a butt-penetrating screw 7 and a jack 8.

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 4, a lifting steel corbel for jacking and storey-adding comprises an upper corbel 1 and a lower corbel 2, wherein a jack 8 is arranged between the upper corbel 1 and the lower corbel 2; go up bracket 1 and frame post 3 fixed connection, lower bracket 2 and the steel slide 4 swing joint on the frame post 3.

Referring to fig. 3 to 4, specifically, T-shaped steel frames 5 are arranged at four corners of a steel slide 4 on a frame column 3, a clamping groove 6 is arranged at the back of the lower bracket 2 corresponding to the T-shaped steel frame 5, the corresponding clamping groove 6 is clamped with the T-shaped steel frame 5 in a matching manner, and after the clamping groove 6 is clamped into the T-shaped steel frame 5, the T-shaped steel frame 5 and the lower bracket 2 are fixed by bolts.

Referring to fig. 3 to 4, specifically, the upper bracket 1 and the frame column 3 are fixedly connected through a through screw 7.

Referring to fig. 1 to 4, the lifting steel corbel is used in a jacking storey-increasing layer of a building, when the lifting steel corbel is used, two upper corbels 1 are arranged on two opposite sides of the upper part of a frame column 3, and the upper corbels 1 and the frame column 3 are fixed through opposite-penetrating screw rods 7. And then, two lower brackets 2 are correspondingly arranged on two opposite sides of the lower section of the frame column 3, a steel slide way 4 is arranged on the outer wall of the frame column 3, and a clamping groove 6 corresponding to the back of the lower bracket 2 is clamped with a T-shaped steel frame 5 on the steel slide way 4 in a matching way and is fixed by a bolt. Subsequently, the jack 8 is installed on the top surface of the lower bracket 2. Jacking through the jack 8 and carrying out building jacking and storey-adding, lower bracket 2 is along with the going on of jacking process, constantly dismantles the installation and upwards removes along the steel slide, until reaching design height.

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.
