Description

Technical Field

[0001] This application relates to the technical field of building construction, and in particular to a construction structure with diagonal bracing at the rear of a column. Background Technology

[0002] In conventional concrete building projects, due to reasons such as increasing floor load, adding cantilever slabs, adding steel staircases, and strengthening, it is often necessary to add diagonal bracing to the columns (concrete columns) to achieve the function of strengthening the structural force transmission.

[0003] Reference Figure 1 The construction process of constructing the diagonal bracing 13 behind the existing column 1 (concrete column) includes the following steps: First, holes need to be drilled in the column 1 (concrete column), then the dust in the holes is cleaned and a chemical agent is put in. Next, the anchoring base plate 11 is connected to the column 1 (concrete column) with chemical anchors 12. Then, the diagonal bracing 13 is welded to the anchoring base plate 11 on site, thereby completing the construction of the diagonal bracing 13 behind the column 1 (concrete column).

[0004] However, the aforementioned technologies have the following problems: drilling, cleaning, and post-installation of chemical anchors increase the number of construction steps and make the process more difficult. The construction process requires high precision, and incomplete cleaning or insufficient chemical treatment can lead to difficulties in ensuring construction quality. Utility Model Content

[0005] To overcome the aforementioned problems, this application provides a construction structure in which diagonal bracing is added after the column is erected.

[0006] The construction structure for adding diagonal bracing after column erection provided in this application adopts the following technical solution:

[0007] A construction structure for supporting a column with diagonal bracing includes a column body, a first sleeve and a second sleeve sleeved around the periphery of the column body, and a diagonal bracing body fixedly connected to the outside of the second sleeve. The first sleeve and the second sleeve are connected by a connector, and the first sleeve and the second sleeve are detachably connected to the column body by fasteners.

[0008] By adopting the above technical solution, the rapid installation and reliable fixation of the construction structure with diagonal bracing after column erection were achieved. Specifically: the first and second sleeves are fitted around the perimeter of the column, and the diagonal bracing is fixedly connected to the outside of the second sleeve. This design avoids the complex steps of drilling, cleaning, and installing chemical anchors required in traditional construction, simplifying the construction process and reducing construction difficulty. The connectors link the first and second sleeves together, ensuring the stability and reliability between them and improving the rigidity of the overall structure. The fasteners, by penetrating through the first and second sleeves, the column, and the second sleeve, further enhance the connection strength between the first and second sleeves and the column, ensuring the overall stability and safety of the structure.

[0009] Preferably, the opening of the first sleeve is provided with a first flange, and the opening of the second sleeve is provided with a second flange. When the first sleeve and the second sleeve are fitted around the periphery of the column, the first flange and the second flange are in contact, and the connector is provided on the in contact first flange and the second flange.

[0010] By adopting the above technical solution, when the first sleeve and the second sleeve are fitted around the periphery of the column, the first flange and the second flange fit together, and the connector is set on the first flange and the second flange that fit together, which ensures a tight connection between the first sleeve and the second sleeve, improves the overall stability and reliability of the structure, simplifies the installation steps, and reduces the construction difficulty.

[0011] Preferably, the connector includes a connecting bolt that passes through the first flange and the second flange in sequence, and a connecting nut that is threadedly connected to the connecting bolt, wherein the first flange and the second flange are positioned between the head of the connecting bolt and the connecting nut.

[0012] By adopting the above technical solution, the connecting bolt passes through the first flange and the second flange, and the head of the connecting bolt and the connecting nut limit the first flange and the second flange, thereby ensuring a firm connection between the first sleeve and the second sleeve, improving the stability and reliability of the structure; at the same time, this connection method is easy to install and disassemble, simplifies the construction process, and reduces the construction difficulty.

[0013] Preferably, the fastener includes a tie rod that passes through the first sleeve, the column and the second sleeve in sequence, and two fastening nuts that are threaded to both ends of the tie rod, with the first sleeve and the second sleeve positioned between the two fastening nuts.

[0014] By adopting the above technical solution, the tie rod passes through the first sleeve, the column and the second sleeve in sequence, and two fastening nuts are threaded to the two ends of the tie rod respectively. The first sleeve and the second sleeve are limited between the two fastening nuts. This design not only improves the connection strength between the first sleeve and the second sleeve and the column, but also ensures the stability and reliability of the entire structure. At the same time, this fastening method simplifies the installation steps, reduces the construction difficulty and improves the construction efficiency.

[0015] Preferably, the inner sides of the first sleeve and the inner sides of the second sleeve are roughened to form a first rough texture, and the periphery of the column is roughened to form a second rough texture.

[0016] By adopting the above technical solution, the setting of the first rough texture and the second rough texture significantly increases the friction between the first sleeve, the second sleeve and the column, and improves the adhesion between them, so that the first sleeve and the second sleeve can be more firmly fixed to the column, thereby enhancing the integrity and stability of the entire structure.

[0017] Preferably, there are two first flanges on the same first sleeve, and the two first flanges are symmetrically arranged on both sides of the first sleeve. Similarly, there are two second flanges on the same second sleeve, and the two second flanges are symmetrically arranged on both sides of the second sleeve.

[0018] By adopting the above technical solution, the setting of two first flanges and second flanges not only improves the connection strength between the first sleeve and the second sleeve, but also ensures the uniform distribution of the connectors, enhancing the overall stability and reliability of the structure; at the same time, the symmetrical setting of the first flanges and second flanges also facilitates on-site installation, simplifies the construction process, and improves construction efficiency.

[0019] Preferably, the connecting parts on the first and second flanges that fit together are provided in two sets, and the two sets of connecting parts are arranged symmetrically from top to bottom.

[0020] By adopting the above technical solution, the connectors on the first and second flanges are arranged in two sets and are symmetrically arranged, which ensures that the connection between the first and second sleeves is more firm and stable, avoids structural loosening or falling off due to single-point stress, and improves the safety and reliability of the overall structure. At the same time, this design also enhances the shear resistance between the first and second sleeves, further improving the load-bearing capacity and service life of the structure.

[0021] Preferably, the fasteners are provided in six groups, and the six groups of fasteners are distributed in a matrix on the second sleeve.

[0022] By adopting the above technical solution, the use of multiple fasteners effectively improves the connection strength between the first and second sleeves and the column, ensuring the overall stability and safety of the structure. Specifically, the six sets of fasteners are distributed in a matrix, which not only evenly distributes the force at each point but also enhances the structure's shear and pull-out resistance, further improving construction quality and structural reliability.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This design enables rapid installation and reliable fixation of the construction structure with diagonal bracing after column erection. Specifically: the first and second sleeves are fitted around the perimeter of the column, and the diagonal bracing is fixedly connected to the outside of the second sleeve. This design avoids the complex steps of drilling, cleaning, and installing chemical anchors required in traditional construction, simplifying the construction process and reducing construction difficulty. Connectors link the first and second sleeves together, ensuring the stability and reliability between them and improving the rigidity of the overall structure. Fasteners, by penetrating through the first and second sleeves, the column, and the second sleeve, further enhance the connection strength between the first and second sleeves and the column, ensuring the overall stability and safety of the structure.

[0025] 2. The connecting bolt passes through the first flange and the second flange, and the head of the connecting bolt and the connecting nut limit the first flange and the second flange, thereby ensuring a firm connection between the first sleeve and the second sleeve, improving the stability and reliability of the structure; at the same time, this connection method is easy to install and disassemble, simplifies the construction process, and reduces the difficulty of construction.

[0026] 3. The tie rod passes through the first sleeve, the column, and the second sleeve in sequence, and two fastening nuts are threaded to both ends of the tie rod. The first and second sleeves are confined between the two fastening nuts. This design not only improves the connection strength between the first and second sleeves and the column, but also ensures the stability and reliability of the entire structure. At the same time, this fastening method simplifies the installation steps, reduces the construction difficulty, and improves construction efficiency. Attached Figure Description

[0032] The following is in conjunction with the appendix Figure 2-4 This application will be described in further detail.

[0033] This application discloses a construction structure for adding diagonal bracing to the rear of a column. (Refer to...) Figure 2 and Figure 3 The construction structure for the diagonal bracing behind the column includes a column 1, a first sleeve 2, a second sleeve 3, and a diagonal bracing body 13. The first sleeve 2 and the second sleeve 3 are both fitted around the periphery of the column 1 and are connected by connectors. The diagonal bracing body 13 is fixedly connected to the outside of the second sleeve 3. In order to make the first sleeve 2 and the second sleeve 3 more securely fixed to the column 1, the first sleeve 2 and the second sleeve 3 are detachably connected to the column 1 by fasteners.

[0034] In this embodiment, column 1 is a concrete column, and the first sleeve 2 and the second sleeve 3 are both steel components with a U-shaped cross section. The diagonal brace 13 is an I-beam. The diagonal brace 13 is welded and fixed to the outside of the second sleeve 3. The steel of the diagonal brace 13 and the second sleeve 3 can be manufactured and welded in the factory to ensure the welding quality at the connection between the steel of the diagonal brace 13 and the second sleeve 3. After the first sleeve 2 and the second sleeve 3 with the welded diagonal brace 13 are transported to the site, the first sleeve 2 and the second sleeve 3 are fitted onto the periphery of column 1. Under the connecting action of the connector, the first sleeve 2 and the second sleeve 3 are spliced ​​together to realize the design concept of assembly and splicing, thereby achieving the purpose of rapid construction.

[0035] The first sleeve 2 has an integrally formed first flange 21 at its opening and on both sides, and the first flange 21 is fixed perpendicularly to the first sleeve 2. The second sleeve 3 has an integrally formed second flange 31 at its opening and on both sides, and the second flange 31 is fixed perpendicularly to the second sleeve 3. When the first sleeve 2 and the second sleeve 3 are fitted onto the periphery of the column 1, the first flange 21 and the corresponding second flange 31 fit together. Connectors are provided on the mating first flange 21 and the mating second flange 31, and there are two sets of connectors on the mating first flange 21 and the mating second flange 31, with the two sets of connectors arranged symmetrically from top to bottom.

[0036] In this embodiment, the connector includes a connecting bolt 4 and a connecting nut 41. The connecting bolt 4 passes through the first flange 21 and the second flange that fit together, and the connecting bolt 4 is threadedly connected to the connecting nut 41. The first flange 21 and the second flange 31 are limited between the head of the connecting bolt 4 and the connecting nut 41.

[0037] To increase the friction between the first sleeve 2 and the second sleeve 3 and the column 1, so that the first sleeve 2 and the second sleeve 3 can be securely fitted onto the periphery of the column 1, improve the adhesion between the first sleeve 2 and the second sleeve 3 and the column 1, and enhance the integrity and stability of the structure; the inner sides of the first sleeve 2 and the second sleeve 3 are roughened to form a first rough texture (not shown in the figure), and the periphery of the column 1 is roughened to form a second rough texture (not shown in the figure).

[0038] Reference Figure 3 and Figure 4 To ensure a more secure fixation of the first sleeve 2 and the second sleeve 3 to the column 1, six sets of fasteners are provided, arranged in a matrix on the second sleeve 3. Each set of fasteners includes a tie rod 5 and two fastening nuts 51 threadedly connected to both ends of the tie rod 5. The ends of the tie rod 5 pass through the first sleeve 2, the column 1, and the second sleeve 3 in sequence, with the first sleeve 2 and the second sleeve 3 confined between the two fastening nuts 51.

[0039] The implementation principle of the construction structure of the column with diagonal bracing in this application embodiment is as follows: Through the modular design of the first sleeve 2 and the second sleeve 3, the diagonal bracing body 13 and the second sleeve 3 are prefabricated and welded in the factory, reducing the amount of on-site welding and improving the welding quality; during on-site construction, it is only necessary to put the first sleeve 2 and the second sleeve 3 on the column 1, and fix the first sleeve 2 and the second sleeve 3 to the periphery of the column 1 by connecting parts and fasteners, which greatly simplifies the construction process, shortens the construction time, and reduces the construction difficulty; at the same time, through the design of the first rough texture, the second rough texture and the fasteners, the connection strength between the first sleeve 2 and the second sleeve 3 and the column 1 is enhanced, and the overall stability and reliability of the structure are improved.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
