Description

Technical Field

[0001] The utility model relates to the technical field of steel structure equipment, in particular to a steel structure connection structure for construction. Background Art

[0002] Steel structure is a building structural system constructed with steel, which has the advantages of high strength, durability and plasticity. The main components of steel structure include steel columns, steel beams, steel frames and steel plates, which are usually manufactured in prefabricated factories and then assembled on site.

[0003] Steel beams are usually installed between two steel columns. When the two steel columns are buried in the ground, there is usually a certain error in the distance between the two steel columns, which may make it impossible for the prefabricated length of the steel beam to be fully installed between the two steel columns. Sometimes it is necessary to cut or weld a part of the steel beam, which greatly increases the construction workload. For this reason, we propose a steel structure connection structure for construction. Utility Model Content

DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0029] See attached Figure 1-6 A steel structure connection structure for construction includes a vertical beam 1 and a horizontal beam 3. A connecting beam 2 is inserted into the vertical beam 1. One end of the connecting beam 2 away from the vertical beam 1 is sleeved on the outer wall of the horizontal beam 3. The three are connected firmly and reliably. By changing the distance between the connecting beam 2 and the vertical beam 1 and the horizontal beam 3, the horizontal beam 3 has a larger fault tolerance when installed between the two vertical beams 1, so that the horizontal beam 3 has more room for adjustment during installation;

[0030] An extension portion 11 extends outward from the side of the vertical beam 1, and a first through hole 12 is vertically opened on the extension portion 11 to pass through the upper and lower surfaces. One end of the connecting beam 2 is inserted into the inner cavity of the extension portion 11, and the inserted end is vertically opened with a first strip groove 21 that passes through the upper and lower surfaces. The first strip groove 21 is arranged in conjunction with the first through hole 12. The connecting beam 2 is horizontally opened with a fourth through hole 22 that passes through the front and rear surfaces thereof. One end of the cross beam 3 inserted into the connecting beam 2 is horizontally opened with a fifth through hole 31 that passes through the front and rear surfaces thereof. During installation, the connecting beam 2 is first sleeved on one end of the vertical beam 1, and the fourth through hole 22 and the fifth through hole 31 are positioned correspondingly, and then bolts are inserted and fixed with nuts. At this time, After the cross beam 3 and the connecting beam 2 are fixed, the connecting beam 2 is inserted into the extension portion 11, and the first strip groove 21 corresponds to the first through hole 12. The first strip groove 21 is in a long strip shape, so that when the connecting beam 2 is inserted into the extension portion 11 at different distances, the first strip groove 21 can pass through the first through hole 12. After the position is adjusted appropriately, a bolt is used to pass through the first through hole 12 and the first strip groove 21, and then fixed by a nut. At this time, the vertical beam 1, the connecting beam 2 and the cross beam 3 are connected and fixed, so that the cross beam 3 has a larger fault tolerance when installed between the two vertical beams 1, and the adjustment room of the cross beam 3 during installation is further improved;

[0031] Among them, at least one of the fourth through hole 22 and the fifth through hole 31 is a strip hole, so that when the connecting beam 2 and the cross beam 3 are connected, the distance that the connecting beam 2 extends out of the cross beam 3 can be changed, and the fault tolerance rate when the cross beam 3 is installed between the two vertical beams 1 can be further improved during installation.

[0032] In this embodiment, the vertical beam 1 and the horizontal beam 3 are symmetrically installed with reinforcing plates 4, and one side of the reinforcing plate 4 fits the surface of the extension part 11, the connecting beam 2 and the horizontal beam 3 in the connected state, so that the connection between the vertical beam 1, the connecting beam 2 and the horizontal beam 3 is more stable, thereby improving the overall supporting capacity.

[0033] In this embodiment, the reinforcing plate 4 is stepped, and one of the stepped surfaces is completely in contact with the end surface of the extension portion 11. The end surface of the extension portion 11 supports the one stepped surface of the reinforcing plate 4, so that the reinforcing plate 4 can provide stronger supporting capacity and improve the supporting effect. There is a gap between the other stepped surface and the end surface of the connecting beam 2, which is convenient for adjusting the position of the connecting beam 2 when it is connected to the vertical beam 1 and the horizontal beam 3.

[0034] In this embodiment, a sixth through hole 41 and a seventh through hole 42 are vertically completely penetrated at both ends of the reinforcing plate 4, a second through hole 14 matching the sixth through hole 41 is formed on the vertical beam 1, and a second strip groove 32 matching the seventh through hole 42 is formed on the horizontal beam 3, so as to facilitate the installation of the reinforcing plate 4 on the vertical beam 1 and the horizontal beam 3.

[0035] In this embodiment, a plurality of triangular support plates 13 are provided on the inner wall of the vertical beam 1 , and one surface of the plurality of triangular support plates 13 is respectively attached to the outer contour surface of the connecting beam 2 , so as to improve the supporting force of the vertical beam 1 on the connecting beam 2 .

[0036] In this embodiment, a plate edge 15 extends outward from the top of the vertical beam 1 , and a plurality of third through holes 16 are formed in the plate edge 15 , so as to facilitate the installation of another vertical beam 1 on the top of the vertical beam 1 .

[0037] In this embodiment, one end of the reinforcing plate 4 extends upward, and the height of the upwardly extended end is the same as the vertical distance from the bottom of the plate edge 15 to the top of the extension portion 11. When the reinforcing plate 4 is installed on the vertical beam 1 and the horizontal beam 3, the upwardly extended end of the reinforcing plate 4 just rests under the plate edge 15, further improving the supporting capacity of the reinforcing plate 4.
