Description

Technical Field

[0001] This utility model relates to the field of steel structure box columns, and in particular to a correction device for steel structure box columns. Background Technology

[0002] With the introduction of dual carbon targets, provinces and cities across the country are vigorously promoting prefabricated buildings to reduce carbon emissions from the construction industry. Steel structures are a crucial structural form in prefabricated building construction, but currently, there is a lack of technical solutions for the correction of steel structure box columns.

[0003] During the installation of steel structure columns, in conjunction with hoisting equipment, professional personnel are required to repeatedly and continuously correct the planar position, elevation, and verticality of the components. The accuracy of the steel structure fundamentally depends on the installation precision of the transfer layer steel structure. Currently, when correcting steel box-type columns at the transfer layer, due to the lack of standardized and mature correction tools, workers often make their own tools based on their experience. Because of varying skill levels among workers, the standards of the tools made are inconsistent, making it difficult to achieve uniformity in on-site operation convenience and practicality, thus reducing construction efficiency.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0020] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises", "made for", etc., shall be understood to include the stated elements or components, without excluding other elements or other components.

[0021] Example 1:

[0022] This embodiment provides a correction device for a steel structure box column, connected to the steel structure box column 1. It is characterized by comprising: a reinforcing bar 2, pre-embedded on one side of the steel structure column; a jack 3, the lifting end of which is fitted into the side of the steel structure column; a fixing member 4, composed of multiple welded plates; and a connecting member 5, overlapping the reinforcing bar 2, the connecting member 5 being a plate-like structure. One end of the fixing member 4 is fitted into the connecting end of the jack 3, and the other end is welded to the connecting member 5. Preferably, the fixing member 4 is embedded within a geological structure and / or an existing stable structure.

[0023] Specifically, in order to standardize the installation and calibration of the steel structure box column 1 and improve installation accuracy and indirectly improve installation efficiency, this embodiment provides a correction device for the steel structure box column, including a reinforcing bar 2, a jack 3, a fixing component 4, and a connecting component 5. The fixing component 4 is embedded in the geological structure and / or the existing stable structure, and corrects the steel structure box column 1 by connecting one end to the jack 3; and fixes the other end to the connecting component 5, and the connecting component 5 is connected to the reinforcing bar 2 to locate its own position.

[0024] The reason why the connecting member 5 positions the correction device for steel structure box columns by connecting the reinforcing bar 2 is that, preferably, the reinforcing bar 2 is set on the bottom extension line of the diagonal of the steel structure box column 1, for aligning and correcting the bottom angle of the cross section of the steel structure box column 1. That is, the reinforcing bar 2 is set at a fixed position relative to the steel structure box column 1, and the correction device for steel structure box columns can fix its own position by overlapping the reinforcing bar 2.

[0025] In a preferred embodiment of this invention, the connector 5 further includes a notch located at its bottom. Preferably, the shape of the notch matches the cross-sectional shape of the reinforcing bar 2, and the interior of the notch overlaps with the reinforcing bar 2.

[0026] Specifically, to more accurately locate its position, the notch is used to overlap with the reinforcing bar 2. The position of the notch is determined from the position of the fixing member 4. Therefore, based on the position of the reinforcing bar 2 and the distance between the notch and the fixing member 4, those skilled in the art can calculate the distance from the fixing member 4 to the steel structure box column 1, and select a suitable jack 3. The lifting end of the jack 3 is placed against the steel structure box column 1, and the connecting end is placed against the plate of the fixing member 4. According to the type of jack 3, the handle is operated correctly to complete the support function of the jack 3. Using the fixed support point of the pre-embedded reinforcing bar 2 and the force of the jack 3, the left and right displacement, correction, and fine adjustment of the box column are completed.

[0027] In a preferred embodiment of this invention, the reinforcing bar 2 has a diameter of 20mm, an exposed length of no more than 100mm, and an embedded length of no less than 200mm in the concrete. The reinforcing bar 2 includes a hook with a length of 5d.

[0028] In a preferred embodiment of this invention, the plate of the fastener 4 is welded as a semi-open triangular column frame structure with a cavity. Specifically, as shown... Figure 1 As shown, the multiple plates of the fastener 4 are welded to form a frame structure. The welds are required to be welded according to the first-class weld quality requirements. The steel plates need to be pre-processed into a bevel shape to ensure the welding quality.

[0029] In a preferred embodiment of this invention, the lifting end of the jack 3 is movably connected to the connecting end, and the steel structure box column 1 is corrected by the relative movement between the lifting end and the connecting end. Specifically, the jack 3 is used to realize the displacement correction and fine adjustment of the box column.

[0030] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
