Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structures, and in particular to a steel structure truss connection node. Background Technology
[0002] A steel truss is a structural component made of steel, consisting of a top chord, a bottom chord, and web members. These members are connected at nodes to form a frame structure of triangular or other geometric shapes. The design of trusses utilizes the strength of the material to effectively distribute forces when subjected to loads, thus supporting large spans without the need for intermediate supports.
[0003] Traditional steel truss construction typically involves hoisting the horizontally and vertically arranged steel trusses onto the steel pipe piles, then adjusting their positions before welding them in place. This process is inconvenient and inefficient, and needs improvement. Utility Model Content
[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a steel structure truss connection node that can improve construction efficiency.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a steel structure truss connection node, comprising:
[0006] Steel pipe piles are vertically installed on the ground.
[0007] The mounting base is horizontally positioned above the steel pipe pile;
[0008] The support tube has a square cross-section and is vertically fixed at the center of the mounting base;
[0009] A steel truss is arranged horizontally and vertically around the support tube;
[0010] The steel truss is provided with an I-beam at the end position, and two sets of angle steel are provided around the support tube. A sliding groove is formed between each set of angle steel for the I-beam to slide into. Bolts are horizontally arranged between each set of angle steel to press the upper end face of the I-beam.
[0011] In a preferred embodiment, the present invention can be further configured such that: a hook is provided at the end of the steel truss, and a hole is provided on the mounting base for the hook to pass through.
[0012] In a preferred embodiment, the present invention can be further configured such that: the inner side of the support tube is provided with an installation hole at an inclination, the I-beam is provided with a threaded hole that connects to the installation hole, and a screw is provided in the installation hole that is screwed into the threaded hole.
[0013] In a preferred embodiment, the present invention can be further configured such that: the mounting base is provided with a support for supporting the steel truss, and the support is provided with a groove for the steel truss to be embedded in.
[0014] In a preferred embodiment, the present invention can be further configured such that a reinforcing plate is provided between two adjacent angle steels.
[0015] In a preferred embodiment, the present invention can be further configured such that a pressure cap for fastening the upper end of the angle steel is horizontally disposed above the support tube.
[0016] In a preferred embodiment, the present invention can be further configured such that: a locking hook is provided on the lower end face of the pressure cap, and a locking groove is provided on the inner wall of the support tube for the locking hook to be inserted.
[0017] In summary, this utility model has the following beneficial effects:
[0018] 1. By setting a sliding snap-fit connection structure, the steel truss and the mounting base can be quickly positioned and connected, and bolts can be used to fix them, thereby locking the two together and completing the quick connection and welding-free fixing, which improves the convenience and efficiency of construction.
[0019] 2. By installing oblique screws between the support pipe and the steel truss, and by installing hooks between the steel truss and the mounting base, the structural strength and connection stability between the steel truss and the mounting base are increased. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.
[0025] like Figure 1 , Figure 2 As shown, a steel structure truss connection node includes a steel pipe pile 1, a mounting base 2, a support pipe 3, and a steel truss 4.
[0026] like Figure 1 , Figure 2 As shown, the steel pipe pile 1 is vertically set on the ground, and the mounting base 2 is horizontally set above the steel pipe pile 1. The support pipe 3 has a square cross-section and is vertically fixed at the center of the mounting base 2. The steel truss 4 is arranged horizontally and vertically around the support pipe 3.
[0027] like Figure 2 , Figure 3 As shown, the mounting base 2 is provided with a support 5 for supporting the steel truss 4. The support 5 is provided with a groove 51 for the steel truss 4 to be embedded in, so as to achieve stable support of the steel truss 4.
[0028] like Figure 2 , Figure 3 As shown, I-beams 6 are installed at the ends of the steel truss 4, and two sets of angle steels 7 are installed around the perimeter of the support pipe 3. A groove 71 is formed between each set of angle steels 7 to allow the I-beams 6 to slide and embed. Bolts 72 are horizontally installed between each set of angle steels 7 to press the upper end face of the I-beams 6. A reinforcing plate 73 is installed between two adjacent angle steels 7 to increase the structural strength between the angle steels 7.
[0029] like Figure 2 , Figure 3 As shown, the inner side of the support tube 3 is inclined with an installation hole 31, and the I-beam 6 is provided with a threaded hole 61 for connecting the installation hole 31. A screw 32 is screwed into the threaded hole 61 in the installation hole 31.
[0030] like Figure 2 , Figure 3 As shown, a hook 41 is provided at the end of the steel truss 4, and a hole 21 for the hook 41 to pass through is provided on the mounting base 2.
[0031] like Figure 2 , Figure 3 As shown, a pressure cap 8 is horizontally installed above the support tube 3 to fasten the upper end of the angle steel 7, so as to seal the upper end of the support tube 3 and the angle steel 7. A locking hook 81 is provided on the lower end face of the pressure cap 8, and a locking groove 33 is provided on the inner wall of the support tube 3 for the locking hook 81 to be inserted.
[0032] When it is necessary to fix the horizontally and vertically arranged steel trusses 4 to the steel pipe piles 1, each steel truss 4 is hoisted so that the I-beams 6 at the ends of the steel trusses 4 slide into the grooves 71 formed by the angle steels 7 around the support pipe 3, thereby achieving rapid positioning of the steel trusses 4.
[0033] Meanwhile, the steel truss 4 is embedded into the groove 51 on the support 5, and the hook 41 on the steel truss 4 passes through the locking hole 21 on the mounting base 2, thereby locking the steel truss 4 to the support base. Finally, the screw 32 is screwed obliquely into the mounting hole 31 and the threaded hole 61 to fix the steel truss 4 to the support tube 3, thus completing the construction and fixation of the horizontal and vertical steel trusses 4.
[0034] Therefore, by setting a sliding snap-fit connection structure, the steel truss 4 and the mounting base 2 can be quickly positioned and connected, and the bolts 72 can be used for fixing to lock the two together, thus completing the quick connection and welding-free fixing between the two, improving the convenience and efficiency of construction.
[0035] Finally, the pressure cap 8 is fastened onto the support tube 3, so that the locking hook 81 on the pressure cap 8 hooks into the locking groove 33 inside the support tube 3, thus completing the fixation of the pressure cap 8 and achieving the sealing of the support tube 3 and the upper end of the angle steel 7.
[0036] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
