Embodiment 1

[0038] Embodiment 1: This embodiment aims to provide a well-shaped modular splicing truss for prefabricated steel structures, which is mainly used for prefabricated steel truss structures. It is a new type of steel that can be modularized and quickly assembled. Structural truss beams can speed up the assembly efficiency of prefabricated steel structure buildings, reduce transportation and construction costs, and facilitate on-site construction and installation, providing new design ideas and construction solutions for prefabricated steel structure building systems.

[0039] In a specific structure, such as Figure 1-4 As shown in , a well-shaped modular splicing truss for prefabricated steel structures, including a splicing unit 1 and a connecting unit 2; where the side of the splicing unit 1 can be connected with the splicing unit 1 at the same level, and both ends pass through The connecting unit 2 is connected with another longitudinal splicing unit 1 to form a splicing tru...

Embodiment 2

[0046] Embodiment 2: This embodiment is basically the same as Embodiment 1, the difference is that this embodiment further explains the specific structure of the connection hole.

[0047] In this example, if Figure 5 As shown in , the connection holes include inner holes, outer holes and mounting holes; the inner holes are located in the middle and correspond to the middle of the upper main chord and the lower main chord, and the outer holes are located in the outer for connecting splicing units from the outside , the mounting hole is used to install the connecting rod.

[0048] During the installation process, the internal hole is located inside, and it is difficult for construction personnel to operate on site. For this purpose, in this embodiment, a conjoined reinforcing plate 6 is provided on the outside of the internal hole, the external hole and the installation hole.

[0049] Such as Figure 15 As shown in , the middle part of the reinforcing plate 6 is provided with...

Embodiment 3

[0051] Embodiment 3: This embodiment is basically the same as Embodiment 1, and the difference is that this embodiment is provided with a reinforced isolation component.

[0052] In this example, if Figure 8 As shown in , the openings of the upper node chord 11 and the lower node chord 14 are matched with a reinforced isolation assembly 4, and the reinforced isolation assembly 4 includes a top plate 41, a partition 42 and a sleeve 43, and the partitions 42 are arranged vertically at intervals At the bottom of the top plate 41, a plurality of splicing bolt partitions are formed, and a sleeve 43 is fixed in each splicing bolt partition. The sleeve 43 corresponds to the connecting hole, and horizontal lines 64 are arranged between the round holes to increase the contact friction. force.

[0053] This embodiment aims to strengthen the connection structure, further increase the maximum applied strength of the splicing bolts, increase the bearing range of the upper node chord and ...

Abstract

The invention belongs to the technical field of civil engineering, and particularly relates to a #-shaped modular splicing truss for a fabricated steel structure. The #-shaped modular splicing truss comprises splicing units and connecting units. U-shaped steel is used as a basic raw material, firstly, an upper node chord member and a lower node chord member are used as fixing foundations, connecting holes are formed in the upper parts of the upper node chord member and the lower node chord member, node web members and side rods are vertically arranged in the middle between the upper node chord member and the lower node chord member so as to form splicing bodies of trapezoid structures, the two same splicing bodies are connected together through an upper main chord member and a lower main chord member so as to form a main body structure with a certain span, then main web members are additionally arranged for stabilization so as to form splicing units with the two ends of I-shaped structures, the splicing body with the two ends of the I-shaped structures is used as a foundation connected with another splicing unit so as to form a structure with a certain length in the horizontal direction, additionally, the four ends which extend out of the two sides can be connected through the connecting rod splicing units in the longitudinal direction so as to form a truss body which can cover a certain area, and more choices are brought to development of a new fabricated steel structure building system.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a well-shaped modular spliced ​​truss for an assembled steel structure. Background technique [0002] Prefabricated steel structure is a natural prefabricated structure, which has been used in bridge structures very early. As the country vigorously promotes prefabricated buildings and green buildings, the application of prefabricated steel structures in the construction field is becoming more and more vigorous, because it is more energy-saving and environmentally friendly than traditional steel-concrete structures. However, at present, there are still many deficiencies in the development of new systems and new nodes of prefabricated steel structures, which also restricts the development of prefabricated steel structures to a certain extent. [0003] In particular, high-rise fabricated steel structure systems and large-span fabricated steel structure systems...
