Abstract
The utility model provides a CP-type node of an assembly type spatial structure, belongs to the field of building structure connecting components, and particularly relates to a connecting node for a space steel structure. The CP-type node aims to solve the problems that the rigidity of an assembly type connecting node of the space steel structure is low, and the adaptability of the assembly type connecting node to changes of connecting rod sections is not high. The CP-type node is composed of node cylinders, high-strength bolts and rod end connectors. The positions of screw holes in middle rib plates used for being welded to the node cylinders can achieve construction positioning of structural rods, and construction difficulty is lowered. By means of the rod end connectors, the angles of the rods in the structure can be adjusted, and the requirement for angles of the rods in different space grid structures is met. The CP-type node of the assembly type spatial structure is simple in structure, convenient to construct, large in flexural rigidity, high in standardization degree and suitable for single-layer reticulated shell structures.

Background technology
Single-layer lattice shell is with its reasonable stress, and materials economy is handsome in appearance various, can cover compared with advantages such as large spaces and become the space structures form having a extensive future.Node is the key components of spatial mesh structure.On the one hand, in space structures, the steel using amount of node accounts for the 20%-50% of total steel using amount conventionally; On the other hand, node rigidity is the principal element that affects spatial mesh structure supporting capacity.Although the welded spherical node coupling stiffness in existing space structure is large, stress performance is good, and site operation difficulty is large and cost is high, fireballing requirement in the time of can not meeting assembling type steel structure construction; And though existing bolted spherical node site operation is convenient, meet the requirement of fabricated construction, but its rotational stiffness is very low, is taken as hinged joint application, and is prohibited to be applied in individual layer spatial mesh structure in design.In addition can only be round steel pipe with the welded spherical node of current employing and the supporting rod member of bolted spherical node.For single-layer lattice shell, adopting rectangular steel pipe or i iron rod member is a kind of better selection, and can be very limited with the matching used node type of this class rod member in Practical Project, cause the efficient single-layer lattice shell structure of this class to be seldom applied in Practical Project.
Utility model content
The purpose of this utility model is in order to solve the lower and node of spatial steel structure assembling connected node rigidity to the not strong problem of institute's link member changes of section compliance, a kind of assembling space structures CP type node to be provided.
Assembling space structures CP type node described in the utility model comprises node cylinder 1, a N middle floor 2, a 2N both sides floor 3 and N rod member end plate 4, and N is more than or equal to 1 integer;
On each rod member end plate 4, be welded with two both sides floors 3, form rod end connector, described two both sides floors 3 are positioned at the homonymy of described rod member end plate 4, and described two both sides floors 3 are all vertical with described rod member end plate 4, the thickness of floor 2 in the middle of the spacing of described two both sides floors 3 equals; On middle floor 2 and both sides floor 3, be provided with at least two bolts hole, in the middle of each, floor 2 is inserted in the space of two both sides floors 3 on a rod end connector, and together with in the middle of described, floor 2 is bolted to by least two with described two both sides floors 3.
Assembling space structures CP type node described in the utility model is applicable to different rod member forms and the sectional dimensions such as rectangular steel pipe or i iron rod member, this realizes construction location by the bolt hole on middle floor 2 and both sides floor 3, and realize the angular adjustment of rod member in space by rod end connector, to meet the requirement of different spaces network to rod member angle.By the adjusting of rod member position in the screwhole position implementation space structure of middle floor 2, and by the adjusting of rod member angle in rod end connector implementation structure, reduced the requirement of member processing and site operation precision.Do not need Site Welding, speed of application is fast, has reduced difficulty of construction and cost.Same node can meet different rod member forms with sectional dimension to the requirement being connected.Compare with existing assembling bolted spherical node, node described in the utility model has good rotational stiffness, compare with common node, rotational stiffness has improved at least tens times, can be applied to make in single-layer lattice shell structure the stress performance of single-layer lattice shell structure to obtain very large improvement.
