Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe column assembly, and more specifically, to an assembled steel horizontal connection device between steel pipe columns. Background Art

[0002] A steel pipe column is a column structure made of steel pipes, usually used in engineering such as buildings, bridges, roads, etc. as part of a support or load-bearing structure. The manufacturing of steel pipe columns usually adopts methods such as welding or bolt connection to connect the steel pipes into the required length and shape. During installation, it is necessary to ensure the verticality and stability of the columns to ensure that they can safely bear the load. Generally speaking, steel pipe columns are important structural components and play an important supporting and load-bearing role in engineering.

[0003] In the related art, to ensure the stability of steel pipe columns, diagonal braces are usually installed vertically and at equal intervals between the steel pipe columns to connect them into a whole, and channel steel or angle steel is welded to the steel columns in the form of diagonal braces. However, most of this construction method is high-altitude operation, and the welding quality is difficult to guarantee, and the safety risk is also high. At the same time, welding may also burn the columns, thereby affecting the overall mechanical properties of the steel pipe columns. Summary of the Utility Model

[0028] Embodiment

[0029] The following is further described in conjunction with specific embodiments. Refer to Figures 1-5 As shown, the utility model is an assembled steel horizontal connection device between steel pipe columns, which includes a horizontal connection frame body 2. The horizontal connection frame body 2 is installed between two steel pipe columns 1. The horizontal connection frame body 2 includes two square steel pipes 21 arranged at intervals. A plurality of scissors braces 22 are installed between the two square steel pipes 21, and the plurality of scissors braces 22 are welded to the two square steel pipes 21.

[0030] Refer to Figure 1 and Figure 2 As shown in and, two groups of first hoop fasteners 3 are installed corresponding to both sides of the horizontal connection frame body 2. The two groups of first hoop fasteners 3 are respectively hooped on the two steel pipe columns 1. The number of each group of first hoop fasteners 3 is two and they are correspondingly located at the four corners of the horizontal connection frame body 2. A pair of clamping plates 31 are fixedly welded on both hoop plates of the first hoop fastener 3. The pair of clamping plates 31 are parallel and arranged at intervals. The pair of clamping plates 31 are used to simultaneously clamp the end of the square steel pipe 21.

[0031] In order to lock the horizontal connection frame body 2 on the first hoop fastener 3, by installing two screw rods 32, the two screw rods 32 are simultaneously passed through a pair of clamping plates 31 and the end of the square steel pipe 21, thereby realizing the fixation of the horizontal connection frame body 2.

[0032] Refer to Figure 2 and Figure 3 As shown in and, a receiving plate 33 is welded at the bottom position of a pair of clamping plates 31. The receiving plate 33 and the pair of clamping plates 31 form a 'U'-shaped cross-section. Rib plates 34 are installed on both sides of the pair of clamping plates 31 facing away from each other. The cross-section of the rib plate 34 is triangular. Both sides of the rib plate 34 are respectively welded on the clamping plate 31 and the hoop plate of the first hoop fastener 3. The rib plate 34 can improve the strength of the first hoop fastener 3.

[0033] Refer to Figure 2 and Figure 4 As shown in and, a protective plate 4 is installed between the two first hoop fasteners 3 on the steel pipe column 1. The protective plate 4 is arched. The arched side of the protective plate 4 faces the horizontal connection frame body 2. Notch grooves 41 are opened at both ends of the protective plate 4. The notch grooves 41 are used to be clamped on the outer wall surface of a pair of clamping plates 31. A clamping groove 42 is opened on the arched side of the protective plate 4. The clamping groove 42 is clamped on the scissors brace 22 on the side close to the steel pipe column 1. The clamping groove 42 can play a limiting role. A reinforcing bolt 43 that penetrates through the scissors brace 22 on the side close to the steel pipe column 1 is threadedly passed through the position of the clamping groove 42 of the protective plate 4.

[0034] In some preferred embodiments, a plurality of locking blocks 44 are welded in the card slots 42 of the guard plate 4. The locking blocks 44 are trapezoidally arranged, and the cross-section of the locking blocks 44 facing the insertion direction is smaller. A plurality of locking openings 221 are correspondingly formed on the cross bracing rod 22 close to the side of the steel pipe column 1. The locking blocks 44 and the locking openings 221 are inserted and matched with each other to facilitate the insertion of the locking blocks 44 into the locking openings 221.

[0035] Referring to Figure 1 and Figure 4 In order to further fix the two steel columns and improve the overall connection strength, a second hoop 5 is also installed between the two first hoops 3 on the steel pipe column 1. The second hoop 5 is hooped on the steel pipe column 1. A reinforcing plate 51 is welded on the hoop plate of the second hoop 5. The reinforcing plate 51 is arched, and the arched side of the reinforcing plate 51 faces away from the horizontal bracing frame body 2. The two ends of the reinforcing plate 51 are respectively welded at positions close to its two ends of the guard plate 4. An elastic sheet 6 is installed between the guard plate 4 and the reinforcing plate 51. The elastic sheet 6 is in a 'V' shape. One end of the elastic sheet 6 is welded to the guard plate 4, and the other end is welded to the reinforcing plate 51. Two elastic sheets 6 are installed and are symmetrically arranged up and down.

[0036] Referring to Figure 2 and Figure 4 Hard rubber plates 7 are installed at both ends of the guard plate 4. One side of the hard rubber plate 7 abuts against the hoop plate of the first hoop 3, and the other side abuts against the guard plate 4. A notch groove 41 for allowing a pair of clamping plates 31 to pass through is also formed on the hard rubber plate 7.

[0037] The working process of this embodiment is as follows: directly hoop the four first hoops 3 in pairs corresponding to the two steel pipe columns 1. The heights of the four first hoops 3 in pairs need to correspond. Then, use the two clamping plates 31 of the first hoop 3 to limit the four corners of the horizontal bracing frame body 2 and fix them with screws 32. Then, install the second hoop 5 at the exact middle position between the two first hoops 3 on the same steel pipe column 1. Fix the guard plate 4 on the horizontal bracing frame body 2 through the reinforcing bolts 43. The notch grooves 41 at both ends of the guard plate 4 are correspondingly clamped to the outer wall surfaces of a pair of clamping plates 31. Install the hard rubber plate 7 between the guard plate 4 and the first hoop 3. The locking blocks 44 of the guard plate 4 need to be correspondingly clamped on the locking openings 221 of the horizontal bracing frame body 2. In this way, the steel pipe column 1 can be reinforced and connected conveniently and safely. The overall installation and disassembly are relatively convenient and can be adjusted appropriately according to the spacing of the columns.
