DETAILED DESCRIPTION

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0019] In the description of the present invention, the terms "horizontal", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0020] like Figure 1-5 As shown, the utility model is a tool-type connection node for connecting wall members of a vertical channel of a steel structure exterior wall, comprising a back plate 2, a grab hook 3, a conversion member 4, and a round tube 14 connecting member 5 arranged in sequence from the inside of the steel structure exterior wall. The back plate 2 is a T-shaped structure as a whole, comprising a bottom plate 6 and a vertical plate 7 connected to the middle of the bottom plate 6. Long oval mounting holes 8 are symmetrically opened on both sides of the vertical plate 7 on the bottom plate 6. The grab hook 3 is arranged in a one-to-one correspondence with the mounting hole 8. A circular hole 9 is opened at one end of the grab hook 3. The diameter of the circular hole 9 is equal to the diameter of the mounting hole 8. The circular hole 9 is on the bottom plate. 6 is provided with a first bolt 10 screwed between one side of the vertical plate 7 and the mounting hole 8 for fastening. The other end of the hook member 3 extends to the outside of the base plate 6 and is provided with a hook groove 11. The notch of the hook groove 11 is set towards the flange of the wall steel column after passing the base plate 6, and is used to hook the corresponding side of the flange of the steel column toward the inside of the steel column. The conversion member 4 is set vertically through the outer wall in the horizontal direction, and one end located on the inner side of the wall is detachably connected to the vertical plate 7, and the other end located on the outer side of the wall is detachably connected to the round tube 14 connector 5. The round tube 14 connector 5 is used to be fixedly connected to the vertical channel.

[0021] The back plate 2 is arranged vertically, and the hook member 3 is fastened to the back plate 2 by the first bolt 10, keeping the plane of the hook member 3 parallel to the extension direction of the mounting hole 8, and the bottom of the hook groove 11 is vertical, so as to fit and hook the flange end of the steel column I-beam 1. The size of the hook groove 11 is matched with the structure of the I-beam 1 to be connected. The vertical plate 7 and the conversion member 4 are generally also connected by bolts. The length, material and thickness of the conversion member 4 can be adjusted according to the thickness of the wall material, so as to facilitate the workpiece to effectively adapt to the drawing performance. The hole left by the conversion member 4 for penetrating the material is smaller, and the subsequent processing is simpler, reducing the risk of water leakage. The round tube 14 connector 5 is generally also connected to the conversion member 4 by bolts.

[0022] This component is used throughout the entire construction process, from the installation of the main structure to the completion of the profiled metal enclosure system. During the structural installation phase, suitable locations for vertical access can be selected based on the layout of the profiled metal sheets. As the primary wall penetration component, the conversion component 4 should minimize damage to the metal sheets. Vertical or horizontal panel seams are selected as the wall penetration locations, and these seams are typically sealed with sealant or trimming components, making later repairs easier and minimizing the risk of leaks.

[0023] There are no specific requirements for the installation process during the main structure installation phase. Before the construction of the corrugated metal sheet begins, you can make minor adjustments to the wall-penetrating parts of the connectors. Change the edge fittings there to butt joints, cut the sides of the edge fittings, and fit them over the connectors. Adjustment steps during the corrugated metal sheet construction phase:

[0024] S1: A hole with the same size as the cross section of the connecting piece is opened on the plate seam edge trim to facilitate the insertion of the edge trim;

[0025] S2: Divide the trim into two parts and install them in a butt-jointed manner;

[0026] S3: After use, remove the vertical channel. During the removal process, you only need to pull out the connector and seal it with sealant.

[0027] If the through-hole is sealed with sealant, a flexible rubber-plastic part can be placed on the conversion part 4 to seal it directly. This will facilitate the removal of the connector after the sealant is sealed, avoiding adhesion between the sealant and the conversion part 4. After removal, the hole can be repaired with sealant. The installation and removal of the vertical channel shall comply with the installation and removal technical requirements and safety operation requirements of the scaffolding.

[0028] The utility model discloses a tool-type connection node for connecting wall members of a vertical channel of a steel structure exterior wall, comprising a back plate 2, a hook member 3, a conversion member 4, and a circular tube 14 connecting member 5, which are arranged in sequence from the inside of the steel structure exterior wall to the outside. The conversion member 4, as a wall-penetrating component, has a small cross-sectional size, which can minimize damage to the original metal wall plate and reduce the difficulty of later repair. The adjacent components are connected by bolts, which facilitates installation and disassembly, thereby improving the material turnover rate. The back plate 2 is provided with an oblong mounting hole 8. According to the width of different steel columns and installation requirements, the circular hole 9 of the hook member 3 is adjusted to align with the mounting hole 8, thereby adjusting the expansion width of the hook member 3 on both sides of the back plate 2. The hook member 3 is then tightened with a first bolt 10 to fix the new spacing of the hook grooves 11 on both sides of the vertical plate 7. It can be adapted to different project structures and a variety of application scenarios. Compared with the existing technology, the installation efficiency is improved, the material usage is economical, and the operation convenience and safety are improved, with good economic and social benefits.

[0029] In another technical solution, Figure 1 As shown, two pairs of mounting holes 8 are symmetrically arranged on the base plate 6 relative to the vertical plate 7. The angle between the extending direction of the mounting holes 8 and the vertical plate 7 is acute, and the ends of the two mounting holes 8 located on the same side of the vertical plate 7 away from the vertical plate 7 are arranged away from each other.

[0030] There are four mounting holes 8 in total, which are arranged symmetrically in two pairs of mounting holes 8. The base plate 6 is a rectangular plate structure with a horizontal length direction. The four mounting holes 8 are respectively close to the center of the base plate 6 at one end and extend toward a top corner of the base plate 6 at the other end, thereby improving the grabbing ability of the grab hook 3 to the steel structure wall structure.

[0031] In another technical solution, Figure 1 As shown, the hook groove 11 is vertically penetrated and the two side walls are arranged parallel to each other, one side wall is the main body of the hook member 3, and the other side wall is arranged as a short plate structure 12. The short plate structure 12 is arranged outward from the extension direction of the bottom of the hook groove 11 relative to the bottom plate 6.

[0032] The side of the hook member 3 with the circular hole 9 is tilted relative to the horizontal plane. The short plate structure 12 is relatively short and does not exceed the range of the bottom plate 6. The short plate structures 12 of all the mounting holes 8 are respectively arranged toward the outside of the back plate 2, thereby expanding the contact area with the steel column flange and balancing the hooking force.

[0033] In another technical solution, Figure 1 As shown, the first bolt 10 is a countersunk bolt with a tenon. The hook member 3 is connected to the back plate 2 through the countersunk bolt with a tenon. The use of the countersunk bolt with a tenon can make the connection between the two parts tighter, and the back plate 2 is not affected when it fits the steel column flange.

[0034] In another technical solution, Figure 1 As shown, the conversion member 4 is a plate-like structure, and both ends of the conversion member 4 are threadedly connected to the vertical plate 7 or the round tube 14 connecting member 5 at the corresponding end through hexagonal bolts 13, which is convenient for tightening or removal.

[0035] In another technical solution, Figure 1 As shown, the circular tube 14 connector 5 includes a circular tube 14 and a head plate 15 covering the end of the circular tube 14. A connecting plate 16 is welded axially outwardly to the middle of the head plate 15. The connecting plate 16 is connected to the conversion member 4 through threads.

[0036] The round tube 14 connector 5 uses a conventional round tube 14 end to add a head plate 15 and a connecting plate 16, which are connected to the conversion piece 4 through bolts. The welding quality of the head plate 15 and the connecting plate 16 of the round tube 14 should be guaranteed to ensure the effective use of the workpiece.

[0037] Although the embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the description and implementation methods. They can be fully applied to various fields suitable for the present invention. For those familiar with this field, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and drawings shown and described herein.
