Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a quick connector for inclined channel steel. Background Technology

[0002] In building construction, angle steel and channel steel are commonly used to connect and form steel structures. These steel structures can be used for the installation of various pipelines. In the assembly of existing steel structures, angle steel and channel steel are usually prefabricated to their lengths during production, transported to the installation location, and then assembled using bolts to form a complete structure. In actual assembly, depending on the specific installation requirements, in addition to horizontal and vertical connections to form the main steel structure, there is also a need to arrange diagonally connected frames on horizontal beams and vertical columns.

[0003] In existing arrangements of inclined connecting frames, there are typically two installation structures: 1. In production, the channel steel is cut at both ends at an angle according to installation requirements to prefabricate the angled connecting frame. During installation, bolts are used to directly tighten the connection. While this structure is convenient to install, it requires prefabrication at the factory, resulting in excessive material preparation and high storage costs. Furthermore, the assembly of the main steel structure requires high precision; excessive installation errors can lead to misalignment of the angled connecting frame.

[0004] 2. During assembly, the channel steel is cut on-site. This eliminates the need for additional stocking and storage of various pre-cut channel steels. When assembly is required, the ends of the channel steel are cut at an angle according to the assembly requirements on-site, and then the channel steel is obliquely fixed to the main steel structure using connectors. Although this structure has low usage and storage costs, it requires high precision in on-site cutting. If the cutting error is too large, the oblique channel steel will not align with the mounting holes on the connectors, resulting in defects.

[0005] Therefore, how to quickly, accurately, and reliably install inclined channel steel on the main steel structure has become an urgent problem to be solved. Utility Model Content

[0006] The technical problem to be solved by this utility model is: in order to overcome the shortcomings of the prior art, this utility model provides a quick connector for inclined channel steel. The positioning hole can be used to complete the initial positioning of the connector body and the inclined channel steel. The arc hole and the bearing bolt assembly can be used to abut against the inclined channel steel to accurately position the inclined channel steel and the connector body. This facilitates the quick, accurate and reliable installation of the inclined channel steel, and does not require too much material preparation, effectively reducing storage and usage costs.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: a quick-connecting component for oblique channel steel, used for obliquely installing channel steel on a frame structure, including a connecting component body, the connecting component body including a web and symmetrically arranged wing plates on both sides of the web; the frame structure has a plurality of frame fixing holes, the web has a plurality of body fixing holes, and the connecting component body and the frame structure are locked and fixed by bolts through the frame fixing holes and body fixing holes; the two ends of the channel steel are respectively obliquely cut to form oblique connecting ends, and the front and rear sides of the channel steel are respectively provided with a plurality of connecting holes, and the connecting holes on the front and rear sides of the channel steel are arranged one-to-one; the wing plates are provided with at least one abutment bearing elongated hole and a plurality of mounting holes, at least one pair of connecting holes on the front and rear sides of the channel steel correspond to the mounting holes on the two wing plates and are locked by bolts, and positioning bolts are also provided through the abutment bearing elongated holes on the two wing plates, the positioning bolts are threaded with positioning nuts, the positioning bolts are positioned and fixed by the positioning nuts and the abutment bearing elongated holes, and the outer peripheral surface is in static friction fit with the channel steel.

[0008] In the above scheme, the oblique connecting ends of the channel steel are machined and cut on-site according to the assembly position requirements. During machining, it is only necessary to ensure that at least one pair of connecting holes on the front and rear sides of this end can correspond to the connecting holes on the connecting body's wing plate to complete the positioning connection between this end and the connecting body. At this time, the positioning bolts are fixed by passing through the positioning nuts through the bearing holes. The positioning bolts are used to press against the contact channel steel to further position the channel steel and effectively load it. This allows for accurate, reliable, and fast installation of the oblique channel steel, and effectively reduces storage and usage costs.

[0009] Furthermore, the abutting bearing elongated hole is an arc-shaped elongated hole. The radial cross section of the arc-shaped elongated hole is formed by a set of long sides and a set of short sides. The set of short sides consists of two arcs arranged symmetrically at the center, and the set of long sides consists of two arcs connecting the two ends of the two arcs respectively, and the two arcs are arranged concentrically.

[0010] Preferably, the mounting holes on the same wing plate are arranged in a group, and the mounting holes in the same group are located on the same radius of the circle containing the long side of the bearing long hole of the wing plate. When selecting the mounting holes, it is necessary to ensure that when positioning and installing the channel steel, the end of the channel steel is located between the selected mounting hole and the bearing long hole. In this way, after the through-connecting positioning bolt, it can effectively form a pressing contact with the end of the channel steel. The positioning and load-bearing functions are further realized through the static friction between the channel steel and the positioning bolt.

[0011] Furthermore, to facilitate the positioning and connection of the mounting hole and the connecting hole, the mounting hole and the connecting hole have the same diameter.

[0012] Furthermore, the frame structure has three sets of frame fixing holes along its length, namely, elongated frame holes and frame fixing round holes symmetrically arranged on both sides of the elongated frame holes; the web also has three sets of body fixing holes along its length, namely, elongated body holes and body fixing round holes symmetrically arranged on both sides of the elongated body holes; when the frame structure is fixed to the web, at least one pair of frame fixing round holes and body fixing round holes are bolted through and locked, and at least one elongated body hole and frame elongated hole are bolted through and locked.

[0013] Furthermore, along the length of the frame structure, the web length is greater than the wing length, and the two ends of the web extend from both sides of the wing. When the frame structure is fixed to the web, the body fixing hole selected for positioning connection is closer to one end of the web, and the body elongated hole selected for positioning connection is closer to the other end of the web.

[0014] The beneficial effects of this utility model are that the quick connector for inclined channel steel provided by this utility model has a reasonable design of the connector body. In the positioning combination of the connector body and the inclined channel steel, the positioning hole is aligned with the mounting hole on the inclined channel steel as a first positioning of the connection. After the first positioning at both ends of the inclined channel steel, the bolt assembly is installed at the arc-shaped hole position. The through bolts are used to abut and lock with the outer circumference of the inclined channel steel, completing the second positioning of the inclined channel steel. At the same time as positioning, it also provides a certain load-bearing capacity for the inclined channel steel. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention. Therefore, they only show the components relevant to the present invention. Orientations and references (e.g., up, down, left, right, etc.) are only used to aid in the description of the features in the drawings. Therefore, the following specific embodiments are not intended to be restrictive, and the scope of the claimed subject matter is defined solely by the appended claims and their equivalents.

[0021] like Figures 1 to 3 The quick-connector for inclined channel steel shown is the preferred embodiment of this utility model. This quick-connector is used for obliquely installing channel steel 3 on a frame structure 1, and includes a connector body 2. The connector body 2 includes a web 24 and wing plates 23 symmetrically arranged on both sides of the web 24.

[0022] In this embodiment, to facilitate the positioning and fixing of the connector body 2 and the frame structure 1, three sets of frame fixing holes are provided along the length direction of the frame structure 1: a frame elongated oval hole 11 and frame fixing round holes 12 symmetrically arranged on both sides of the frame elongated oval hole 11. Three sets of body fixing holes are also provided along the length direction of the web plate 24: a body elongated oval hole 26 and body fixing round holes 25 symmetrically arranged on both sides of the body elongated oval hole 26. When the frame structure 1 is fixed to the web plate 24, a pair of frame fixing round holes 12 and body fixing round holes 25 are bolted through and locked, and a body elongated oval hole 26 is bolted through and locked to the frame elongated oval hole 11.

[0023] Along the length of frame structure 1, the web 24 is longer than the flange 23, and both ends of the web 24 extend from the sides of the flange 23. In selecting the body fixing circular hole 25 and the body elongated hole 26 for positioning and connection, to ensure force balance, when frame structure 1 is fixed to web 24, the body fixing hole for positioning and connection is selected closer to one end of web 24, and the body elongated hole 26 for positioning and connection is selected closer to the other end of web 24. Thus, the positions of the pair of body fixing circular holes 25 and body elongated holes 26 form three bolt locking points. These three bolt locking points constitute a locking plane, achieving rapid positioning of the connector body 2 and frame structure 1.

[0024] In the oblique channel steel 3 connection, both ends of the channel steel 3 are obliquely cut to form oblique connection ends 32. Several connection holes 31 are opened on the front and rear sides of the channel steel 3, and the connection holes 31 on the front and rear sides of the channel steel 3 are set one-to-one. The wing plate 23 has a bearing-bearing elongated hole 21 and several mounting holes 22. Among the several pairs of mounting holes 22 on the front and rear sides of the channel steel 3, one pair of connection holes 31 corresponds to the mounting holes 22 on the two side wing plates 23 and is locked with bolts. In the selection of mounting holes 22 and connection holes 31, round holes can be used, and the diameter of the mounting holes 22 and the connection holes 31 are the same. The bearing-bearing elongated holes 21 on the two side wing plates 23 are also provided with positioning bolts 4. Positioning nuts are threaded on the positioning bolts 4. The positioning bolts 4 are positioned and fixed with the bearing-bearing elongated holes 21 through the positioning nuts, and the outer peripheral surface of the positioning bolts 4 is in static friction fit with the channel steel 3.

[0025] Specifically, the bearing-supporting elongated hole 21 is designed as an arc-shaped elongated oval hole based on the ordinary elongated oval hole. The radial cross-section of this arc-shaped elongated oval hole is formed by a set of long sides and a set of short sides. The set of short sides consists of two arcs arranged symmetrically at the center, and the set of long sides consists of two arcs connecting the two ends of the two arcs respectively, and the two arcs are concentrically arranged. In the distribution design of the mounting holes 22, the mounting holes 22 on the same flange 23 are arranged in groups. The mounting holes 22 in the same group are located on the same radius of the circle containing the long side of the bearing-supporting elongated hole 21 of the flange 23. When selecting the mounting holes 22, it is necessary to ensure that when positioning and installing the channel steel 3, the end of the channel steel 3 is located between the selected mounting hole 22 and the bearing-supporting elongated hole 21. In this way, after the through-connecting positioning bolt 4, an effective pressing contact can be formed with the end of the channel steel 3. The positioning and load-bearing functions are further realized through the static friction cooperation between the channel steel 3 and the positioning bolt 4.

[0026] Assembly process: Based on actual assembly requirements, a suitable installation location is selected, and the installation position is determined on the main steel structure. Two connecting parts are then fixed to the main steel structure using bolts. Next, a channel steel 3 of suitable length is selected, and both ends of the channel steel 3 are cut at an angle to create oblique connecting ends 32. One oblique connecting end 32 of the channel steel 3 is brought into contact with the web plate 24 of one connecting part body 2, and moved along the plane of the web plate 24 to ensure that there is a pair of mounting holes 22 between the front and rear sides of the channel steel 3 and the flange plate 23 for alignment. Bolts are then used to tighten the connection. The other oblique connecting end 32 of the channel steel 3 is similarly tightened. At this point, the position of the oblique channel steel 3 can be observed through the abutment bearing elongated hole 21 on the flange plate 23. Positioning bolts 4 are inserted into the abutment bearing elongated holes 21 on both flange plates 23 and moved along the holes until they abut against the channel steel 3. Positioning nuts are then used to fix the positioning bolts 4 to the flange plate 23. The same operation is performed on the other oblique connection end 32 of the channel steel 3, thus completing the installation of the oblique channel steel 3 on the main steel structure using quick connectors.

[0027] This design of a quick-connect fitting for inclined channel steel features a rationally designed fitting body 2. During assembly, the inclined connecting end 32 of the channel steel 3 is machined and cut on-site according to the assembly position requirements. During machining, it is only necessary to ensure that at least one pair of connecting holes 31 on the front and rear sides of this end corresponds to the connecting holes 31 on the connecting body wing plate 23 to complete the positioning connection between this end and the fitting body 2. The positioning holes are aligned with the mounting holes 22 on the inclined channel steel 3, serving as the first positioning for the connection. Then, positioning bolts 4 are fixed through the bearing long hole 21 by positioning nuts. The positioning bolts 4 are used to press against the channel steel 3. Bolt assemblies are installed at the arc-shaped hole position, and the through bolts are used to abut and lock against the outer circumference of the inclined channel steel 3, completing the second positioning of the inclined channel steel 3. While positioning, the channel steel 3 can also be further positioned and effectively loaded. The positioning connection is accurate, reliable, and fast, and effectively reduces storage and usage costs.

[0028] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
