Description

A kind of bolt connection node being applicable to rectangular steel pipe single-layer lattice shell
Technical field
The utility model relates to large-span space structure connected node, in particular, relates to a kind of bolt connection node being applicable to rectangular steel pipe single-layer lattice shell.
Background technology
Existing " spatial mesh structure tecnical regulations " (JGJ7 ?2010) regulation, single-layer lattice shell should adopt rigid joint, as welded spherical node, tubular joint etc., rod member many employings round steel pipe, rectangular steel pipe and H profile steel, but the node being applicable to rectangular steel pipe rod member is less, there are dividing plate welding node, thick walled steel tube node, tubular joint and cast steel node etc. at present, but these joint forms all Shortcomings.Dividing plate welding node and thick walled steel tube node need Site Welding, and weld seam is more, construct loaded down with trivial details, are unfavorable for the development of industrialization of construction industry, and too much weld seam can affect joints performance; The size of tubular joint to supervisor and arm there are certain requirements, and constrains its application; But cast steel node function admirable high cost, is unsuitable for applying on a large scale.Therefore, a kind of convenient and quick construction need be developed, the rectangular steel pipe monolayer net shell nodal that stress performance is excellent.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, a kind of bolt connection node being applicable to rectangular steel pipe single-layer latticed shell is provided, this node can facilitate rectangular steel pipe single-layer lattice shell rod member to connect, ensure connection stiffness and bearing capacity, reduce fusion length, reduce welding heat affected, simplify construction technology, be beneficial to engineering and apply.
The purpose of this utility model is achieved through the following technical solutions:
A kind of bolt connection node being applicable to rectangular steel pipe single-layer lattice shell, comprise rectangular steel pipe and connected node, described connected node is hollow cylindrical structure, the inner surface hoop of described hollow cylinder is disposed with arc pad, what the external surface of hollow cylinder was corresponding is provided with arc junction plate, arc pad, to be bolted between hollow cylinder and arc junction plate, described arc junction plate is fixedly connected with rectangular steel pipe, and the axis of rectangular steel pipe and the axis of hollow cylinder intersect at a point.
Described bolt is full tooth bolt.
Circular arc radian on described arc pad and arc junction plate fits with the inner surface of hollow cylinder and external surface respectively.
Described arc junction plate is also provided with holddown groove.
The junction of described bolt and arc junction plate is provided with improved mat.
Described arc junction plate and rectangular steel pipe are fixed by welding manner.
Described arc junction plate and the vertical connection angle scope of rectangular steel pipe are 0 °-20 °.
Compared with prior art, the beneficial effect that the technical solution of the utility model is brought is:
1. the utility model connected node is hollow cylindrical structure, the surfaces externally and internally of hollow cylinder is symmetrical is respectively provided with arc pad and arc junction plate, arc pad, to be bolted between hollow cylinder and arc junction plate, arc junction plate and rectangular steel pipe are welded and fixed, and the axis of rectangular steel pipe and the axis of hollow cylinder intersect at a point; Therefore the Path of Force Transfer of the utility model node is clear and definite, and node is by the axle masterpiece used time, and axle power is passed to node by bolt tension or the extruding between arc junction plate and node body; When node is subject to Moment, moment of flexure is by the pulling force of bolt and the extruding force transmission between arc junction plate and node body;
2. arc pad in the utility model connected node, be bolted between hollow cylinder and arc junction plate, and do not use welding manner to connect at Nodes, can not impact connection stiffness and bearing capacity, overall bending rigidity is higher, carries out reinforcement during the Lack of support of node own by the inside mode such as to put more energy into.In addition, node is after prefabricated completing, and can realize on-the-spot quick-assembling and repeat dismounting, technique is simple, reliable and stable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model will be further described:
As shown in Figures 1 to 4, a kind of bolt connection node being applicable to rectangular steel pipe single-layer lattice shell, comprise rectangular steel pipe 2 and connected node, connected node is made up of hollow cylinder 1, the inner surface hoop of hollow cylinder 1 is disposed with arc pad 3, what the external surface of hollow cylinder 1 was corresponding is provided with arc junction plate 4, arc pad 3 and the circular arc radian on arc junction plate 4 fit with the inner surface of hollow cylinder 1 and external surface respectively, arc pad 3, be connected by bolt 5 between hollow cylinder 1 with arc junction plate 4, bolt 5 is full tooth high-strength bolt, and be furnished with improved mat, arc junction plate 4 is provided with holddown groove 6, to be fixedly connected with rectangular steel pipe 2 by welding manner, in the present embodiment, hollow cylinder 1, arc pad 3 be provided with connecting hole in arc junction plate 4 and be connected to facilitate, wherein the connecting hole of arc junction plate 4 is screwed hole.
As shown in Figure 5 and Figure 6, rectangular steel pipe axis 8 and hollow cylinder axis 7 intersect at a point, and the arc junction plate 4 connection angle scope vertical with rectangular steel pipe 2 is 0 °-20 °.
