Abstract
The strut lower node of a kind of Levy type cable dome structure, belongs to technical field of buildings.The base supported by the termination of upper bands otic placode and lower bands is formed by connecting by connecting elements bolt.It is connected with the outer oblique cord of Levy type cable dome structure by two otic placodes of periphery of termination, top, is connected with montant lower node by the top otic placode of termination, top, carry out the fixing of bottom strop the most again.When fixing bottom strop, first pass through bolt and pull down the lower base of node, then bottom strop is put into node precalculated position by reserving hole channel, the most again lower base is installed and put in place and utilize bolt to fix, bottom strop i.e. installation.The present invention gives the strut lower node of a kind of Levy type cable dome structure, it is adaptable to the construction of Levy type cable dome structure, it is to avoid the trouble of the installation difficulty that Levy type cable dome structure causes more greatly due to continuous and rope head at work progress middle and lower part strop.
Description
Technical field:
The present invention relates to the strut lower node of the Levy type cable dome structure of a kind of building field application, belong to Building technology
Field.
Background technology:
The appearance of cable dome structure serves good facilitation for the development of space structure technology in modern times, it
Proposition is stretch-draw total concept based on famous American architect Mr. fowler.This structure maximally utilised material and
The characteristic in cross section, has therefore obtained good application in large-span space structure field.Such as Korea S gymnasium, U.S.'s thunder vault
Top, American Red bird gymnasium, Japan's city, sky dome, China science and technology interchange centre, Wuxi, China's Erdos Yi Qi civic movements
The building such as center all adopts the structure form, and therefore, the installation of Cable dome also obtains people and increasingly comes the most passes
Note.For installation, node is the big factor affecting Cable dome construction speed.Levy type cable dome structure is different from
The structures such as suspen-shell structure, its feature be hoop rope be continuous print, and be flexible structure, brace should be protected in installation process simultaneously
Card can turn an angle in mounting plane.The node of existing large-span space structure has the disadvantage that
The conventional node such as bolted spherical node, welded hollow spherical joints, the angle between rod member and rod member can not change.Install
During easily produce mount stress, bring initial strain to rod member.And cable dome structure can not be met continuously and for flexible
The installation requirement of strop.
Summary of the invention
It is an object of the invention to combine the feature of Levy type cable dome structure, propose the support of a kind of Levy type cable dome structure
Bar lower node, this strut lower node is after installation process, it is ensured that single continuous hoop rope is pacified at each node simultaneously
Install to position, make the brace of Levy type cable dome structure can rotate in mounting plane around node simultaneously, it is possible to meet
Levy type cable dome structure is the change requirement of angle between rod member during construction and installation, overcomes in work progress in rod member
Portion produces the phenomenon of moment of flexure.
The purpose of this invention is achieved through the following technical solutions:
The strut lower node of a kind of Levy type cable dome structure, it is characterised in that this node is by the termination of upper bands otic placode
The base supported with lower bands is formed by connecting by connecting elements bolt；
Termination (2) the main body lower end of upper bands otic placode is internal is circle hollow structure, on the wall that circle hollow structure is corresponding certainly
Lower surface upwards has two U-shaped through-hole grooves (6) stood upside down；It is provided with screw thread in termination (2) the main body lower surface of upper bands otic placode
Hole (7)；Termination (2) main body lateral surface at upper bands otic placode is provided with two periphery otic placodes, and periphery otic placode band is porose；In upper bands
The upper surface of termination (2) main body of otic placode is provided with a top otic placode (4) with holes；
The base (3) that lower bands supports is chassis below, and the upper surface on chassis is provided with two column type support (8), and column type is propped up
The upper surface of support (8) has semi-circular recesses；The base (3) that the termination (2) of upper bands otic placode supports with lower bands is by being connected
When component bolt connects, the lower surface of the termination (2) of upper bands otic placode is positioned at the upper surface on base (3) chassis that lower bands supports
On, the size of two column type support (8) matches with two U-shaped through-hole grooves (6) stood upside down, and two column type support (8) are the most right
Should insert in two U-shaped through-hole grooves (6) stood upside down, and the U-shaped through hole of the semi-circular recesses of column type support (8) upper surface and handstand
The circular arc top combination of groove (6) constitutes a circular hole；Chassis is provided with bolt hole, the base (3) lower bands supported by bolt
The fixing connection with the termination (2) of upper bands otic placode.
Two U-shaped through-hole grooves (6) stood upside down can be offered in different positions as required, in the most corresponding circle
The angle of hollow structure can become as required.
Be connected with montant lower node by the top otic placode (4) of termination, top of the present invention, by two otic placodes of periphery with
The outer brace of Levy type cable dome structure is connected, and turns bolt and it is fixed temporarily, now termination (2) position of upper bands otic placode
Substantially stationary, montant and outer brace the most all can carry out a range of relatively rotating around this node, under carrying out the most again
The fixed installation of portion's strop, when fixing bottom strop, first passes through demounting bolt and pulls down the base (3) that lower bands supports, so
After using bottom strop by stand upside down U-shaped through-hole groove as reserving hole channel to U-shaped through-hole groove top, the most again by lower bands support
Base (3) install put in place and utilize bolt to fix, bottom strop i.e. installation.
Otic placode on the termination (2) of upper bands otic placode includes top otic placode and side otic placode.Top otic placode is used for connecting
The lower node of the vertical strut of Levy type cable dome structure, side otic placode is used for connecting the lower joint of Levy type cable dome structure brace
Point.Otic placode direction, side on the termination (2) of upper bands otic placode is consistent with the direction, termination of Levy type cable dome structure brace,
Ensure that it connects smoothly.After all components being connected with this node connect and put in place and be fixing, this node still can carry out one
Determine the rotation of angle, meet Levy type cable dome structure in work progress for the requirement of joint rotation, the most convenient
The installation of Levy type cable dome structure.
The present invention takes full advantage of the technique of design and construction of existing space structure node, has simultaneously taken account of Levy type
The feature of cable dome structure, has simple structure, easy construction, reduces the difficulty of construction of Levy type cable dome structure, it is ensured that
The synchronization that can carry out multiple node under strop continuous print state is installed, ensure simultaneously brace and montant can around joint rotation,
Avoid Levy type cable dome structure to produce in brace owing to node can not rotate with overall lifting in stretching process in construction
The phenomenon of raw moment of flexure.
