Description
Technical field
The present invention relates to the mounting method of member in a kind of steel work, but the mounting method of the individual layer rigid joint of a kind of free forming of more specifically saying so.
Background technology
For satisfying the sand dune moulding in 2010 Shanghai World's Fair United Arab Emirates shops, adopted the single-layer lattice shell structure in United Arab Emirates shop, finish the detachability that venue strange land, back rebuilds utilization for satisfying World Expo simultaneously, the single-layer lattice shell node must adopt bolt to connect, at present, adopting bolted single-layer lattice shell structure to there is no the similar engineering experience can use for reference.
External existing a kind of NOVUM node, but the NOVUM node is a kind of individual layer rigid joint of free forming, as Fig. 1, in the existing abroad case history of NOVUM node only based on the small area applications on roof lighting top and so on, adopt moulding bed to support location and installation, promptly at location moulding bed of each NOVUM node lower support, and measure the coordinate of moulding bed and member contact point, guarantee that with the location of moulding bed the installation of node is accurate.Though this method location is more accurate, the moulding bed location is loaded down with trivial details, and moulding bed also needs the node secondary repetition measurement that carries out in place behind the location, and installation rate is slower.
The single-layer lattice shell Structural Engineering net shell area in United Arab Emirates shop reaches 2678 square metres, if according to the existing mounting method of NOVUM node, and then can oversize can not meeting the demands of duration.
Summary of the invention
The present invention is for avoiding above-mentioned existing in prior technology weak point, but the mounting method that a kind of accurate positioning, installation rate are fast, be applied in the individual layer rigid joint of the free forming in the large tracts of land engineering is provided.
Technical solution problem of the present invention adopts following technical scheme:
But the characteristics of the mounting method of the individual layer rigid joint of the present invention's free forming are:
But the mounting method of the individual layer rigid joint of the present invention's free forming is characterized in operating as follows:
A, mounting platform is set by setting up full hall scaffold;
B, be support with described mounting platform, set up steel pipe support above the NOVUM node, the support vertical rod in the described steel pipe support is the vertical rod extension bar in the full hall scaffold; The central point Chain block is set on steel pipe support, utilizes the central point Chain block NOVUM node to be hung the below that is located at steel pipe support;
C, measure, utilize the central point Chain block to regulate the position of NOVUM node, make that the node center point three-dimensional coordinate of described NOVUM node is consistent with design load promptly adjusts to the right place for the three-dimensional coordinate of described NOVUM node center;
D, when described NOVUM node is adjusted to the right place, rod member is hung to mounting platform, one end of rod member adopts bolt tentatively to be connected with the NOVUM node, keep rod member for can participate in hinged active state, the far-end Chain block that utilization is arranged on the steel pipe support is hung up the other end of rod member, adjust the angle of rod member by the far-end Chain block, meet the design point requirement until the angle of rod member;
E, rod member and NOVUM node are tentatively tightened with bolt, on the same NOVUM node with face node mutually and have the rod member of connection and the assembly unit of NOVUM node in place after, carry out bolt and twist eventually and promptly finish installation.
But the characteristics of the mounting method of the individual layer rigid joint of the present invention's free forming also are the measurement of described central point three-dimensional coordinate for the NOVUM node, it is the upper surface central point three-dimensional coordinate that the central point three-dimensional coordinate of NOVUM node is converted into node, the upper surface central point three-dimensional coordinate of each NOVUM node is corresponding to the central point three-dimensional coordinate of a node, identifies with the center of " ten " word upper surface central point to described NOVUM node at the upper surface of described NOVUM node.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the central point three-dimensional coordinate of the present invention by measuring N OVUM node, and be located with the consistent location of realizing of design coordinate figure for the NOVUM node, it is easy for installation, rapid;
2, the present invention adopts steel pipe support lower than moulding bed expense, and dismounting is faster, accurate positioning.
Description of drawings
Fig. 1 is NOVUM node structure schematic diagram among the present invention;
Fig. 2, Fig. 3 are the different erection stage schematic diagram of the present invention;
Number in the figure: 1 mounting platform, 2 is NOVUM node, 3 central point Chain blocks, 4 steel pipe supports, 5 support vertical rods, 6 far-end Chain blocks, 7 rod members, 8 holes, 9 jack devices.
The specific embodiment
The present embodiment mounting method is operated as follows:
1, by setting up full hall scaffold mounting platform 1 is set;
2, be support with mounting platform 1, set up steel pipe support 4 above NOVUM node 2, the support vertical rod 5 in the steel pipe support 4 is the vertical rod extension bar in the full hall scaffold; Central point Chain block 3 is set on steel pipe support 4, utilizes central point Chain block 3 NOVUM node 2 to be hung the below that is located at steel pipe support 4;
3, measure for the three-dimensional coordinate of NOVUM node center, utilize central point Chain block 3 to regulate the position of NOVUM nodes 2, make that the node center point three-dimensional coordinate of NOVUM node 2 is consistent with design load promptly adjusts to the right place;
In concrete the enforcement, measurement for the central point three-dimensional coordinate of NOVUM node 2, it is the upper surface central point three-dimensional coordinate that the central point three-dimensional coordinate of NOVUM node is converted into node, the upper surface central point three-dimensional coordinate of each NOVUM node is corresponding to the central point three-dimensional coordinate of a node, identify with the center of " ten " word upper surface central point at the upper surface of NOVUM node 2, determine the accuracy of node location during in-site measurement by the centre of surface point three-dimensional coordinate of measured node the NOVUM node.
4, when NOVUM node 2 is adjusted to the right place, rod member 7 is hung to mounting platform 1, adopt bolt tentatively to be connected between one end of rod member 7 and the NOVUM node 2, it not is fixedly connected for tight condition that the bolt of this moment connects, the preliminary connection needs to keep rod member 7 for can participate in hinged active state, the far-end Chain block 6 that utilization is arranged on the steel pipe support 4 is hung up the other end of rod member 7, adjust the angle of rod members 7 by far-end Chain block 6, meet the design point requirement until the angle of rod member 7;
