Technical Field

[0001] The utility model relates to the field of construction, in particular to a rectangular steel tube lattice shell support node. Background Art

[0002] In recent years, in order to meet the requirements of building use functions, large-span spatial structures have been increasingly used in engineering practice, such as public and industrial buildings such as terminal buildings, exhibition centers, toll booths, and large-span coal sheds. Among the many structural forms, the lattice shell structure is a curved grid structure that combines the characteristics of simple bar structure construction and reasonable stress of thin shell structure. It has the characteristics of large span capacity, good rigidity, less materials, a single bar structure, and easy manufacture and installation.

[0003] At present, the connection method of metal profile rods of metal lattice shell structures mostly adopts node plate connection. When installing the lattice shell structure, it is usually necessary to set the support point of the support system on the node plate. The traditional support method is to use the frame top support of the support system to support the node plate, and set square wood between the node plate and the frame top support for support. Since the shape of the metal lattice shell structure is a non-planar structure and the slopes at the support points are also different, the traditional node plate support method not only cannot ensure the stability of the force direction of the support point, but also causes the node plate to slide easily, posing a large construction safety hazard.

An auxiliary support member 3 extending outward is fixed to the bottom of the support seat 1, and the outer end of the auxiliary support member 3 is supported on the bottom of the cross bar 2.

[0024] This type of rectangular steel tube grid shell support node usually has the characteristics of large volume and heavy weight. The above-mentioned structure is all made of steel. Therefore, in order to make the cross bar 2 stably set on the support seat 1, the auxiliary support member 3 is tilted upward from the inside to the outside, and the outer end of the auxiliary support member 3 is in contact with the bottom of the cross bar 2 and fixed to each other. The auxiliary support member 3 includes a connecting portion 4 connected to the support seat 1, and a fixing portion 7 connected to the cross bar 2 and supporting and fixing the cross bar 2. Specifically, in this embodiment, the auxiliary support member is configured as a rectangular structure, and the size and shape of the auxiliary support member 3 can also be adjusted according to actual conditions. Since the auxiliary support member 3 is arranged obliquely and fixedly connected to the support seat 1, refer to the attached Figure 4 Therefore, after the cross bar 2 is fixed to the auxiliary support member 3 which is arranged at an angle, the gravity generated by the cross bar 2 will be borne by the auxiliary support member 3 and the support seat 1, thereby improving the stability of the structure.

[0025] In order to further improve the stability of the structure, a side wall auxiliary member 6 extending outward is fixed on the side wall of the support seat 1. The side wall auxiliary member 6 is provided with a pair and is arranged on both sides of the auxiliary support member 3. The outer ends of the side wall auxiliary members 6 are fixedly connected to the side walls of the crossbar 2. Specifically, refer to the attached Figure 4: In this embodiment, the auxiliary support member 3 is inclined from the inside to the outside, and the bottom of the side wall auxiliary member 6 is tightly fitted with the auxiliary support member 3, so the bottom of the side wall auxiliary member 6 presents an inclined surface state matching the auxiliary support member 3, and the upper surface of the base 8 of the support seat 1 is flat. In order to further improve the stability of the auxiliary support member 3 fixed on the support seat 1, a support portion 5 extending into the interior of the support seat 1 and in contact with the support seat 1 is provided at the connection between the side wall auxiliary member 6 and the auxiliary support member 3, wherein the top of the side wall auxiliary member 6 is connected to the bottom of the cross bar 2 and supports the cross bar 2, and the cross bar 2 is arranged in a cubic shape. In order to make the top of the side wall auxiliary member 6 fit tightly with the bottom of the cross bar 2 to improve the stability of the support, the side support member is arranged in a plane and extends to the inside of the support seat 1 and fits with the inner surface of the support seat 1.

[0026] The support seat 1 includes a polygonal base 8 and a top plate 9 fixedly mounted above the bottom plate and matching the bottom plate. Since the auxiliary support member 3 is in a cubic state, the edges thereof are all flat. In order to enable the auxiliary support member 3 to be stably mounted on the bottom plate, the polygonal base 8 can ensure that the connection between the auxiliary support member 3 and the bottom plate can fit tightly, thereby improving the stability of the connection.

[0027] In order to further improve the stability of the support node, in this embodiment, the cross bar 2 includes an auxiliary cross bar 11 fixedly mounted on a plurality of auxiliary support members 3 and a main support bar 12 designed inside the support seat 1 and exposed at both ends, wherein one end of the auxiliary support bar is connected to the auxiliary support member 3 and the side wall auxiliary member 6, and the other end extends outward in a horizontal state, and the main support bar 12 is arranged in a penetrating state inside the support seat 1.
