Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to an H-shaped steel splicing piece. Background Art

[0002] Steel structures are structures made of steel and are one of the main types of building structures. They primarily consist of components such as beams, columns, and trusses made from sections and plates. They utilize rust removal and prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing. Steel is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation, making it particularly suitable for the construction of large-span, ultra-high, and ultra-heavy buildings. The material exhibits excellent homogeneity and isotropy, making it an ideal elastic body that best conforms to the basic assumptions of general engineering mechanics. The material also exhibits excellent plasticity and toughness, allowing for significant deformation and excellent resistance to dynamic loads. Construction periods are short, and its high degree of industrialization allows for highly mechanized, specialized production.

[0003] H-shaped steel is an economical and efficient profile. Since all parts of the H-shaped steel are arranged at right angles, it has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structural weight, and has been widely used.

[0004] During the construction process, it is often necessary to splice H-shaped steel according to actual conditions. Using flat steel plates to connect the two H-shaped steel webs and flanges is a common splicing method. However, the flat steel plates connecting the webs and the flat steel plates connecting the flanges are separate, that is, there is a connecting plate on each side of the web and a connecting plate on the upper and lower flanges. The connection strength is not strong and stable enough. Utility Model Content

[0017] Optionally, the second connecting plate is mainly composed of a waist plate and leg plates symmetrically arranged at the upper and lower ends of the waist plate, and its cross section is a "[" structure;

[0018] An H-shaped spacer is formed between two second connecting plates symmetrically arranged on one side of the partition and two first connecting plates arranged at the upper and lower ends of the partition, for accommodating the H-shaped steel to be spliced;

[0019] The second connecting hole is formed on the waist plate.

[0020] Optionally, a third connection hole is further provided on the second connection plate, and the third connection hole is provided on the leg plate and corresponds to the first connection hole.

Of course, they are only examples and are not intended to limit the present invention.

[0043] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0044] See also Figures 1 to 5 As shown, the utility model provides an H-shaped steel splicing piece, comprising:

[0045] Partition 10;

[0046] A first connecting plate 20 is used to connect the flange plates of two H-shaped steels to be spliced; and

[0047] The second connecting plate 30 is used to connect the webs of the H-shaped steel to be spliced;

[0048] Among them, the first connecting plates 20 are symmetrically arranged at the upper and lower ends of the partition 10; the second connecting plates 30 are symmetrically arranged on the left and right sides of the partition 10 and located between the first connecting plates 20; two second connecting plates 30 are symmetrically arranged on each side of the partition 10.

[0049] Specifically, the first connecting plate 20 is provided with a plurality of first connecting holes 21, and the second connecting plate 30 is provided with a plurality of second connecting holes 31. During splicing, the ends of the two H-beams (not shown) to be spliced ​​are respectively placed against the left and right sides of the partition 10. The first connecting plate 20 is bolted through the first connecting holes 21 to connect to the flanges of the two H-beams. The second connecting plate 30, which is symmetrical in front and back, is bolted through the second connecting holes 31 to connect to the web of the one H-beam, thereby clamping the web of the H-beam and completing the splicing. That is, after the first connecting plate 20 and the second connecting plate 30 are respectively connected to the flanges and webs of the H-beam, they are then connected to each other through the intermediate partition to form a single unit, resulting in a high-strength, secure, and stable connection.

[0050] The multiple first connection holes 21 are divided into two groups, each group contains two rows and each row has three first connection holes 21 distributed at equal intervals, which are used to connect the flange plates of the H-shaped steel to be spliced, that is, each group of first connection holes 21 is connected to the flange plate of an H-shaped steel through bolts; there are four second connection holes 31 evenly distributed at equal intervals.

[0051] See also Figures 1 to 3 As shown, the first connection hole 21 and the second connection hole 31 are both waist-shaped holes, so that the splicing piece can be adjusted during splicing to reduce splicing errors, thereby ensuring the reliability of the connection between the splicing piece and the H-shaped steel to be spliced.

[0052] In this embodiment, the first connecting hole 21 and the second connecting hole 31 are both waist-shaped holes, and their length directions are perpendicular to each other, that is, the splicing piece can be adjusted from two directions respectively, further reducing the H-beam splicing error.

[0053] See also Figure 1 and Figure 5 As shown, the second connecting plate 30 is mainly composed of a waist plate and leg plates symmetrically arranged at the upper and lower ends of the waist plate, and its cross-section is a "[" structure (i.e., a groove structure); an H-shaped gap is formed between the two second connecting plates 30 symmetrically arranged on one side of the partition 10 and the two first connecting plates 20 arranged at the upper and lower ends of the partition 10 to accommodate the H-shaped steel to be spliced; a second connecting hole 31 is opened on the waist plate.

[0054] See also Figure 3 As shown, the second connecting plate 30 also has a third connecting hole 32, which is located on the leg plate and corresponds to the first connecting hole 21. This means that bolts passing through the first and third connecting holes 21 and 32 on the leg plates of the first and second connecting plates 20 and 30 can secure the flange of the H-beam, further enhancing the connection's strength. In this embodiment, the third connecting hole 32 is a waist-shaped hole, and its length is the same as that of the waist-shaped first connecting hole 21.

[0055] See also Figure 3 As shown, a guide plate 33 is connected to the outer end of the waist plate (i.e., the end away from the partition 10). The guide plates 33, symmetrically arranged on two second connecting plates 30 on one side of the partition 10, are arranged relative to each other to form a trumpet-shaped structure. Guided by the guide plates 33, the H-beams to be spliced ​​are more easily inserted into the H-shaped gap, reducing deviation and adjustment during splicing, thereby improving splicing efficiency.

[0056] See also Figure 4 As shown, the connection between the guide plate 33 and the waist plate is smoothly transitioned, which can reduce the friction between the H-shaped steel to be spliced, ensure that the H-shaped steel to be spliced ​​can smoothly enter the H-shaped interval, and further improve the splicing efficiency.

[0057] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.
