Description

Technical Field

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

[0002] H-shaped steel is an economical and efficient profile with a more optimized cross-sectional area distribution and a more reasonable strength-to-weight ratio. It is named because its cross-section is the same as the English letter "H". Since all parts of the H-shaped steel are arranged at right angles, the H-shaped steel has the advantages of strong bending resistance in all directions, simple construction, cost savings and light structure weight. For these H-shaped steels, they often do not have the conditions for connection and require additional transition structures to connect the H-shaped steels. Therefore, H-shaped steel connectors have been widely used.

[0003] After searching, it is found that the existing H-beam connector has a structure of a connecting plate and multiple connecting bolts, and the connecting plate and the H-beam can be stably connected by bolts. However, the above H-beam connector still has shortcomings. First, it can only connect H-beams in a fixed direction, and requires multiple bolts, which is cumbersome to operate. Second, it is only suitable for connecting two H-beams, which is not practical enough.

[0015] Furthermore, drainage holes are provided on both sides of the middle of the upper surface of the support steel plate;

[0016] Through the above technical solution, if it rains, rainwater can be discharged through the drain outlet, and the H-shaped steel and connecting parts will not be corroded due to the accumulation of rainwater.

[0017] Furthermore, saw teeth are fixedly provided at the lower ends of the four circular steel plate clamps;

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] A stable H-shaped steel connecting piece comprises four brackets 13 and a supporting connecting piece. A supporting steel plate 6 is fixedly provided on the upper ends of the four brackets 13. The H-shaped steel needs to be placed close to the supporting steel plate 6. Four first bolts 1 are threadedly sleeved on the inner sides of the supporting steel plate 6. A circular steel plate clamp 2 is fixedly connected to the lower ends of the four first bolts 1 for fixing the H-shaped steel. First nuts 4 are threadedly sleeved on the lower ends of the four first bolts 1. The H-shaped steel is stably fixed by adjusting the first bolts 1 and the first nuts 4. A third bolt 18 is threadedly sleeved on the middle inner sides of the supporting steel plate 6. A third nut 17 is threadedly sleeved on the lower end of the third bolt 18. A cable chain ring 16 is fixedly provided on the upper end of the third bolt 18. The cable chain ring 16 is fixed by the third bolt 17 and the third nut 18, thereby increasing the practicality of the connecting piece.

[0032] The front sides of the four brackets 13 are threadedly sleeved with two second bolts 7, and the rear ends of the eight second bolts 7 are threadedly sleeved with second nuts 8. The H-shaped steel inserted is fixed by the second bolts 7 and the second nuts 8, so that the H-shaped steel can be stably connected. Two longitudinal fixing holes 14 are penetrated on the upper front sides of the four brackets 13, and two adjustment ports 12 are penetrated on the lower front sides of the four brackets 13. The adjustment ports 12 enable the connector to adjust the position of the fixed steel plate 10 according to the type of H-shaped steel inserted. The lower ends of the four brackets 13 are buckled with grab hooks 9, and the position of the fixed steel plate 10 is adjusted by using the grab hooks 9. The fixed steel plate 10 is fixedly provided at the rear end of the grab hooks 9. Two transverse fixing holes 11 are provided inside the steel plate 10. If the H-shaped steel is inserted transversely in H shape, the H-shaped steel can be fixed through the two transverse fixing holes 11. Drain holes 5 are provided on both sides of the middle of the upper surface of the supporting steel plate 6. Rainwater can be discharged through the drain holes 5. Saw teeth 3 are fixed on the lower ends of the four circular steel plate clamps 2. The saw teeth 3 can enable the circular steel plate clamps 2 to clamp the H-shaped steel stably. Four steel plate clamp fixing holes 15 are provided inside the four corners of the supporting steel plate 6. A cable chain hole 19 is provided inside the middle of the upper surface of the supporting steel plate 6. The connection between H-shaped steels or the connection between H-shaped steels and cable chains can be constructed according to needs, which increases practicality.

[0033] Working principle: During the operation of the utility model, one side of the H-shaped steel is horizontally or vertically drawn under the four circular steel plate clamps 2, and the H-shaped steel is fixed by adjusting the first bolt 1 and the first nut 4. The four circular steel plate clamps 2 have serrations 3, which can firmly clamp the H-shaped steel. The installation is simple when in use, and no on-site welding is required. At the same time, another H-shaped steel to be connected is placed in the bracket 13 through. If the H-shaped steel is placed forward, it is screwed and fixed by the second bolt 7 and the second nut 8. If the H-shaped steel is placed horizontally, it is fixed by bolts and nuts through the horizontal fixing hole 11. According to the size of the H-shaped steel, the grab hook 9 can be placed in different adjustment ports 12 to adjust the fixed position of the grab hook 9. The above operation enables the connector to stably connect the H-shaped steel, and it can be adjusted at any time. The fixing angle of the H-shaped steel can be adjusted by disassembling it at the same time, which solves the problem that the connecting piece can only fix the H-shaped steel in one direction. At the same time, the drain port 5 on the supporting steel plate 6 allows rainwater to be discharged from the H-shaped steel and the connecting piece, which has the effect of resisting rainwater corrosion. When in use, the four circular steel plate clamps 2 can be removed from the four steel plate clamp fixing holes 15 of the supporting steel plate 6 by rotating the first bolt 1 and the first nut 4, and then the third bolt 18 and the third nut 17 are installed through the cable chain hole 19 reserved on the supporting steel plate 6, so as to achieve the purpose of installing the cable chain ring 16 on the supporting steel plate 6. According to the use requirements, the H-shaped steel can be connected to structures such as cable chains through the cable chain ring 16, so that the connecting piece has two connection functions, which greatly increases the practicality of the connecting piece.
