Description

Fixing structure of newly-increased steel beam on concrete column

Technical Field

The utility model relates to a building structure, in particular to fixed knot who increases the girder steel on concrete column constructs.

Background

The building industry in China has been developed rapidly for decades, various buildings such as bamboo shoots are pulled out of the ground after being rainy, and the number of the built buildings is very large. Along with the development of economy in China and the improvement of living standard of people, the requirements of people on the functions and the quality of buildings are higher and higher, some old buildings cannot meet the use requirements of people, but the buildings do not reach the service life or the standards of dismantling, so that the existing buildings need to be modified in building structures to meet the new requirements of people on buildings at new times.

When a new beam is added to the concrete column, the new concrete beam is usually adopted, however, the new concrete beam needs to be subjected to the step of longitudinal bar planting, and structural damage is caused to the concrete column.

Therefore, aiming at the defects in the prior art, a fixing structure which is relatively convenient and quick to construct, can realize rigid connection at a node, transmit large bending moment, and is safe and reliable is needed to be designed.

SUMMERY OF THE UTILITY MODEL

For overcoming the not enough among the above-mentioned prior art, the utility model aims to provide a fixed knot who increases the girder steel on the concrete column constructs.

In order to achieve the above objects and other related objects, the present invention provides a technical solution: the utility model provides a fixed knot of steel beam newly increases on concrete column constructs, includes concrete column, set firmly on the concrete column and embrace the post roof beam, the surface of embracing the post roof beam adopts pre-buried steel sheet parcel, be equipped with on two relative faces of embracing the post roof beam with the newly-increased steel beam of pre-buried steel sheet rigid connection.

The preferable technical scheme is as follows: and chiseling out an existing protective layer on the concrete column, implanting shear-resistant short reinforcing steel bars and coating a concrete interface agent in sequence at the position, corresponding to the column embracing beam, on the concrete column before pouring the column embracing beam.

The preferable technical scheme is as follows: when the column embracing beam is poured, anchor bars with end parts exposed on the surface of the column embracing beam are pre-embedded, holes corresponding to the anchor bars are formed in the steel plate, and the steel plate is fixedly connected with the column embracing beam in a plug hole penetrating welding mode.

The preferable technical scheme is as follows: an inner ring stirrup group and an outer ring stirrup group are arranged in the column holding beam, and the outer ring stirrup group is limited through four vertical steel bars.

Because of the application of the technical scheme, the utility model discloses the beneficial effect who has does:

the utility model discloses a mode of wearing the keyhole to weld sets up the steel sheet on the surface of embracing the post roof beam, and the steel sheet is connected with the girder steel rigid coupling again, has avoided traditional newly-increased roof beam (concrete beam) to indulge the muscle and need pass the problem that the concrete column caused the damage to the post structure, its simple structure, and construction convenience is fit for promoting.

Detailed Description

The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to fig. 1-2. It should be understood that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the position or positional relationship based on the position or positional relationship shown in the drawings, or the position or positional relationship that the product of the present invention is usually placed when in use, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element to which the term refers must have a specific position, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance. The terms "horizontal", "vertical", "overhang" and the like do not imply that the components are required to be absolutely horizontal or overhang, but may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

In the description of the present invention, it should be further noted that, unless otherwise explicitly stated or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may include, for example, a fixed connection, a detachable connection, an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, and a connection between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Example (b):

as shown in fig. 1-2, the fixing structure for the new steel beam on the concrete column provided by the present invention comprises a concrete column 1.

The innovation points are as follows:

a column beam 2 is fixedly arranged on a concrete column 1, a steel plate 4 is fixedly arranged on the surface of the column beam 2, and two opposite surfaces of the column beam 2 are rigidly connected with a newly-added steel beam 3 through the steel plate 4.

Firstly, chiseling an existing protective layer at a selected position on a concrete column 1, then implanting short shear-resistant steel bars 6, then coating a concrete interface agent (so as to ensure the shear-resistant bearing capacity of a joint surface of a column holding beam 2 and the concrete column 1), and finally pouring a column holding beam 2 (an inner ring stirrup group 21 and an outer ring stirrup group 22 are arranged in the column holding beam 2, and the outer ring stirrup group 22 is limited through four vertical steel bars 23).

It needs to be supplemented that when the column holding beam 2 is poured, the anchor bars 5 with the end parts exposed on the surface of the column holding beam 2 are pre-buried.

Then, a steel plate 4 is prepared, holes 41 corresponding to the anchor bars 5 are reserved in the steel plate 4, and the steel plate 4 and the post embracing beam 2 are fixedly connected in a plug-through hole welding mode.

And finally, selecting two opposite surfaces of the column-holding beam 2, and rigidly connecting the newly-added steel beam 3 with the corresponding steel plate 4.

Therefore, the utility model has the advantages of it is following:

The above embodiments are merely illustrative of the principles and effects of the present invention, and are not to be construed as limiting the invention. Modifications and variations can be made to the above-described embodiments by those skilled in the art without departing from the spirit and scope of the present invention.
