Description

Technical Field

[0001] The utility model belongs to the technical field of bridge construction, and in particular relates to a notch type steel pipe column pile head structure. Background Art

[0002] With the rapid development of construction in my country, trestles are becoming increasingly important in bridge construction. Traditional trestles consist of five components: steel tubular columns, load-bearing beams, Bailey beams, distribution beams, and steel decking. The construction process involves driving the steel tubular columns into the ground, placing the load-bearing beams on the column head pads, laying the Bailey beams on top of the load-bearing beams, and finally placing the distribution beams and steel decking on top of the Bailey beams. During on-site installation, the load-bearing beams can shift, or vibrations from the loads above can cause the underlying structure to shift. This can lead to localized stress concentration in the steel tubular columns, compromising their load-bearing capacity and, in turn, the overall structural safety and stability.

[0003] In the prior art, there are disclosed steel pipe column head structures. For example, CN220789722U discloses a steel pipe column head structure capable of bearing eccentric loads, comprising a steel pipe pile head, an annular top plate, vertical ear plates, side ear plates, annular plates, and a limit plate. The outer edge of the steel pipe pile head is sleeved with an annular top plate, two vertical ear plates are provided on both sides of the steel pipe pile head, two side ear plates are provided on both sides of the vertical ear plates, a limit plate is provided between the vertical ear plates and the side ear plates, and several layers of annular plates are provided below the annular top plate. The steel pipe column head structure disclosed in this patent places an annular plate above the column cap and leaves a hole for the steel pipe pile, avoiding the upper end of the steel pipe pile. Load-bearing beams can be set on both sides, changing the original single-support load to a double-support load. When the load-bearing beam or pile head undergoes horizontal displacement due to eccentric load, the eccentric bending moment is smaller than that of a single-support load when multiple supports are applied, and the overall structure is safer when subjected to eccentric loads.

[0004] It is undeniable that the steel pipe column pile head structure disclosed in this patent can indeed achieve the above-mentioned effects, but it still has certain shortcomings: it has many additional parts such as annular top plates, vertical ear plates, side ear plates, annular plates and limit plates, and there are many connection points, which to a certain extent increases the difficulty of manufacturing and installation; and more connection points require more time to maintain to ensure the long-term stability of the structure.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0006] The purpose of the utility model is to provide a notch type steel pipe column pile head structure to solve the problem of eccentrically bearing steel pipe column pile head structure in the background technology.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A slotted steel pipe column pile head structure, comprising:

[0009] A steel pipe column pile head, wherein limit slots are symmetrically provided on both sides of the top of the steel pipe column pile head;

[0010] A load-bearing beam, the load-bearing beam passes through the steel pipe column pile head from the limiting notch; the bottom of the load-bearing beam is welded to the bottom wall of the limiting notch, and both sides of the load-bearing beam are fixedly connected to the outer wall of the steel pipe column pile head through a connecting plate;

[0011] A support member is welded inside the pile head of the steel pipe column and abuts against the bottom of the load-bearing beam.

[0012] Preferably, the load-bearing beam is fixed with a plurality of reinforcing plates distributed along its length direction; the connecting plate is composed of an integrally formed arc plate and a straight plate; the arc plate is welded to the outer wall of the steel pipe column pile head; the straight plate is welded to the reinforcing plate of the load-bearing beam.

[0013] Preferably, the support member is composed of two support plates welded in a cross shape, and the outer ends of the support plates are welded to the inner walls of the steel pipe column pile heads.

[0014] Preferably, the height of the load-bearing beam is greater than the depth of the limiting notch.

[0015] Preferably, one connecting plate is provided on each side of the limiting notch.

[0016] Preferably, an arc-shaped reinforcement plate is welded on the outer wall of the steel pipe column pile head located just below the limiting notch, and the top of the arc-shaped reinforcement plate is flush with the bottom wall of the limiting notch.

[0017] Preferably, the width of the arc-shaped reinforcement plate is greater than the width of the limiting notch.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The steel pipe column pile head and the load-bearing beam of the utility model are directly connected through the limiting notch, which reduces the stress concentration of the steel pipe column pile head in structure and improves the bearing performance of the steel pipe column. At the same time, the limiting notch has a limiting effect on the load-bearing beam, thereby enhancing the overall stability of the structure. In addition, the support member abuts against the bottom of the load-bearing beam and thus produces a supporting effect on the load-bearing beam, so that the steel pipe column pile head evenly bears the load transmitted by the load-bearing beam. Secondly, the arc-shaped reinforcement plate can strengthen the local bearing capacity of the limiting notch of the steel pipe column pile head and prevent the limiting notch from being locally compressed and causing large deformation. In addition, the connecting plate can play a limiting role on the load-bearing beam, which can enhance the stability of the overall structure. The structure is simple and stable, with few parts and connection points, which is convenient for manufacturing, installation and maintenance. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The steel pipe column pile head 100 has limit slots 101 symmetrically formed on both sides of the top of the steel pipe column pile head 100. In addition, an arc-shaped reinforcement plate 102 is welded to the outer wall of the steel pipe column pile head 100 directly below the limit slot 101. The top of the arc-shaped reinforcement plate 102 is flush with the bottom wall of the limit slot 101, and the width of the arc-shaped reinforcement plate 102 is greater than the width of the limit slot 101.
