Description

Technical Field

[0001] The utility model relates to the technical field of high-rise building construction, in particular to a high-rise steel structure corridor. Background Art

[0002] High-rise steel structure corridor is an important building structure. It not only provides a convenient passage between floors of high-rise buildings, but also realizes the effective use of space and functional division. The corridor in the relevant technology is a rigid connection structure, that is, the corridor and the main structure are directly welded or cast into a whole. However, there is no movable space at the connection between the main body and the corridor. Once an earthquake occurs, the displacement of the main body and the corridor will generate a large shear force, causing the connection to rupture or even be pulled off, causing the corridor to collapse.

[0003] Therefore, it is necessary to provide a new high-rise steel structure corridor to solve the above technical problems. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a high-rise steel structure corridor.

[0006] The high-rise steel structure corridor also includes a carrying steel frame, the carrying steel frame is used to set up the steel frame beam connection end is provided with an opening, and the carrying steel frame is installed with a telescopic component and a side pressure component;

[0007] The telescopic assembly includes a plug-in plate, on which an accordion-shaped steel plate is fixedly mounted, and an abutment plate is fixedly mounted on the other end of the accordion-shaped steel plate;

[0008] The side pressure assembly includes a sliding bar, which is inserted into an installation cavity opened on the inner wall of the mounting steel frame. The insertion end of the sliding bar is elastically connected to the inner wall of the installation cavity, and the other end of the sliding bar is embedded with a rolling steel ball.

[0009] Preferably, the insertion plate is inserted into an insertion groove provided in the carrying steel frame, and the abutment plate abuts against the end of the steel frame beam inserted into the carrying steel frame.

[0010] Preferably, sound-absorbing cotton is fixedly embedded on the folded plate surface of the accordion-shaped steel plate.

[0011] Preferably, a spring is fixedly mounted on the insertion end of the sliding bar, and the other end of the spring is fixedly connected to the inner cavity wall of the mounting cavity.

[0012] Preferably, the inner walls on both sides of the mounting steel frame are provided with a plurality of evenly distributed installation cavities, and a side pressure assembly is provided in each of the installation cavities.

[0013] Preferably, a waist-shaped hole B is provided on the bottom wall of the carrying steel frame near the opening, and a fixing bolt for passing through the waist-shaped hole A is installed on the waist-shaped hole B.

[0014] Preferably, an embedded base is fixedly welded to the bottom of the carrying steel frame, a through cavity is provided on the embedded base which passes through the embedded base transversely, and a plurality of evenly distributed grooves are provided at the bottom of the embedded base.

[0015] Compared with the related art, the high-rise steel structure corridor provided by the utility model has the following beneficial effects:

[0016] When the thermal expansion and contraction factors cause the steel frame beam to slide inward or outward along the carrying steel frame, the compressed accordion-shaped steel plate provides elastic buffering to weaken the longitudinal shear force, thereby effectively preventing the connection between the corridor body and the carrying steel frame from being broken or even pulled apart due to excessive shear force, which is beneficial to improving the stability of the connection between the building body and the corridor body. When the carrying steel frame deviates laterally, the steel balls of the carrying steel frame abut against the lateral deviation direction so that the sliding bar compresses the spring, thereby weakening the lateral shear force of the carrying steel frame. Moreover, since the steel balls on the sliding bar are in a rolling arrangement, it is convenient to insert the steel frame beam into the carrying steel frame. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0025] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0026] See also Figures 1 to 6 An embodiment of the utility model provides a high-rise steel structure corridor, which includes a corridor body 1, a carrying steel frame 2, a telescopic component 3 and a side pressure component 4, and four steel frame beams 11 are arranged on the corridor body 1, and the four steel frame beams 11 are fixedly connected by connecting steel frames, and waist-shaped holes A11a are opened at both ends of each steel frame beam 11.

[0027] In the embodiments of the present invention, please refer to Figure 1 The bottom of the carrying steel frame 2 is fixedly welded with an embedded base 5, the embedded base 5 is provided with a through cavity 5a which passes through the embedded base 5 transversely, and the bottom of the embedded base 5 is provided with a plurality of evenly distributed grooves 5b.

[0028] It should be noted that: before erecting the corridor body 1, when the two buildings are used to carry the steel frame beams 11 in the carrying steel frame 2, the carrying steel frame 2 is pre-embedded in the building carrying area. Specifically, the embedded base 5 at the bottom of the carrying steel frame 2 is placed in the installation area, and then concrete is poured in the area. The groove 5b set at the bottom of the embedded base 5 improves the stability of the embedded base 5 when it is placed, and the concrete can pass through the through cavity 5a opened in the embedded base 5, so that the embedded base 5 is installed more firmly.

[0029] In the embodiments of the present invention, please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5The carrying steel frame 2 is provided with an opening at the connection end for erecting the steel frame beam 11, and a telescopic assembly 3 is installed in the carrying steel frame 2, and the telescopic assembly 3 includes an insertion plate 31, on which an accordion-shaped steel plate 32 is fixedly installed, and an abutment plate 33 is fixedly installed at the other end of the accordion-shaped steel plate 32, and the insertion plate 31 is inserted into the insertion groove 2a provided in the carrying steel frame 2, and the abutment plate 33 abuts against the end of the steel frame beam 11 inserted into the carrying steel frame 2;

[0030] A waist-shaped hole B2c is formed on the bottom wall of the carrying steel frame 2 near the opening, and a fixing bolt 6 for passing through the waist-shaped hole A11a is installed on the waist-shaped hole B2c.

[0031] It should be noted that: after the pre-embedded mounting steel frame 2 is installed, the insertion plate 31 is inserted into the insertion slot 2a provided in the mounting steel frame 2, and then the steel frame beam 11 is inserted into the mounting steel frame 2 and the insertion depth of the steel frame beam 11 is adjusted so that the accordion-shaped steel plate 32 is compressed and fixed with the fixing bolts 6;

[0032] When the steel frame beam 11 slides inward or outward along the carrying steel frame 2 due to thermal expansion and contraction, the compressed accordion-shaped steel plate 32 provides elastic buffering to weaken the longitudinal shear force, thereby effectively preventing the connection between the corridor body 1 and the carrying steel frame 2 from being broken or even pulled apart due to excessive shear force, which is beneficial to improving the stability of the connection between the building body and the corridor body 1;

[0033] Among them, sound-absorbing cotton 34 is fixedly embedded on the folded plate surface of the accordion-shaped steel plate 32, which can absorb the noise generated by the steel frame 2 when the end of the steel frame beam 11 moves sideways.

[0034] In the embodiments of the present invention, please refer to Figure 3 and Figure 6 The inner walls on both sides of the carrying steel frame 2 are provided with a plurality of evenly distributed installation cavities 2b, and each of the installation cavities 2b is provided with a side pressure assembly 4;

[0035] The side pressure assembly 4 includes a sliding bar 41, which is inserted into an installation cavity 2b opened on the inner wall of the mounting steel frame 2, and the insertion end of the sliding bar 41 is elastically connected to the inner cavity wall of the installation cavity 2b. Specifically, a spring 42 is fixedly installed at the insertion end of the sliding bar 41, and the other end of the spring 42 is fixedly connected to the inner cavity wall of the installation cavity 2b, and the other end of the sliding bar 41 is embedded with a rolling steel ball 43.

[0036] It should be noted that: when the carrying steel frame 2 deviates to the side, the steel balls 43 of the carrying steel frame 2 abut against the deviating direction so that the sliding bar 41 compresses the spring 42, thereby weakening the lateral shear force of the carrying steel frame 2. In addition, since the steel balls 43 on the sliding bar 41 are arranged to roll, it is convenient to insert the steel frame beam 11 into the carrying steel frame 2.

[0037] The working principle of the high-rise steel structure corridor provided by the utility model is as follows:

[0038] Before erecting the corridor body 1, when two buildings are used to carry the steel frame beams 11 in the carrying steel frame 2, the carrying steel frame 2 is pre-embedded in the building carrying area. Specifically, the embedded base 5 at the bottom of the carrying steel frame 2 is placed in the installation area, and then concrete is poured in the area. The groove 5b provided at the bottom of the embedded base 5 improves the stability of the embedded base 5 when it is placed, and the concrete can pass through the through cavity 5a opened in the embedded base 5, so that the embedded base 5 is installed more firmly;

[0039] After the mounting steel frame 2 is pre-buried and installed, the insertion plate 31 is inserted into the insertion groove 2a opened in the mounting steel frame 2, and then the steel frame beam 11 is inserted into the mounting steel frame 2 and the insertion depth of the steel frame beam 11 is adjusted to compress the accordion-shaped steel plate 32, and fixed with the fixing bolts 6;

[0040] When the steel frame beam 11 slides inward or outward along the carrying steel frame 2 due to thermal expansion and contraction, the compressed accordion-shaped steel plate 32 provides elastic buffering to weaken the longitudinal shear force, thereby effectively preventing the connection between the corridor body 1 and the carrying steel frame 2 from being broken or even pulled apart due to excessive shear force, which is beneficial to improving the stability of the connection between the building body and the corridor body 1;

[0041] When the carrying steel frame 2 deviates to the side, the steel balls 43 of the carrying steel frame 2 abut against the deviated direction, causing the sliding bar 41 to compress the spring 42, thereby weakening the lateral shear force of the carrying steel frame 2. In addition, since the steel balls 43 on the sliding bar 41 are arranged to roll, it is convenient to insert the steel frame beam 11 into the carrying steel frame 2.

[0042] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
