Abstract
The invention aims to solve the technical problem of designing and assembling a pin type connecting mechanism which is suitable for multi-rod piece cross nodes in a large-span wood latticed shell structure. The connecting mechanism comprises a profiled bar connecting piece, a continuous wood rod piece, a discontinuous wood rod piece, a through bolt and a pin, and is characterized in that the profiled bar connecting piece is formed by welding a reversed groove-shaped piece and four steel plates in an oblique crossing manner, and in order to facilitate accurate positioning and assembly on site, openings are respectively and upwards formed in the positions of upper rows of reserved holes of the four steel plates. The wood bar members were not continuous at the nodal connections, except that 1 wood bar member was continuous at the nodal connections. The connecting piece has the advantages of easy uniform specification, batch production, convenient construction, high field installation speed, relatively light weight of the joint part, small exposed surface of the steel connecting piece and pure wood structural appearance when viewed from bottom to top.
Description
Technical field
The present invention relates to building structure field, more rod piece crossover nodes for being mainly used in large span wood latticed shell structure.
Background technique
Timber has the advantages that green, environmental protection, reduction energy consumption etc. are a variety of, and China is greatly developing green building, mentions energetically
Timber structure is advocated, for reducing energy consumption, protection environment is of great significance and the important directions of future architecture development.
Timber structure refers to that main bearing member is wooden engineering structure, progress and people's life water with modern technologies
Flat raising, contemporary Chinese timber structure are also flourishing, and timber structure application range extends to modern architecture from traditional architecture,
It is constantly being broken through in terms of span, height, large-scale timber structure public building has had increase trend in China.
Dome structure is one of structure type more classical in large span timber structure, using it is more be monolayer net shell
System, node is the significant points in large span timber structure, and node has become by the way that metal connecting piece is attached at present
Mainstream, but majority all embeds steel plate using steel hub, steel clamp plate or T-type to be connect with the wooden component, rigidity is larger, and metal part
From great, also unsightly, in conventional coupling arrangement metal connecting piece part usually it is exposed in air, not only with wooden atmosphere
Inaccurate coordination also influences the durability of steel, therefore the position of joints greatly across timber structure material self weight, speed of application, appearance
And durability needs to be improved.
Summary of the invention
Object of the present invention is to design a kind of assembled bindiny mechanism for more rod pieces intersection in large span wood latticed shell structure
Node realizes the quick connection between rod part and metal connecting piece, and rod part is made to provide certain connection stiffness, mitigates node
Divide self weight, while reducing the exposed face of metal connecting piece.

The pin hole (31) of pin (41) diameter matches, while being preset and pin (41) diameter matches in the upside of continuous rod part (2)
Pin hole (11), pin hole (11) depth need not be very big, the supreme row of aperture to wearing on bolt, not with bump against to wearing bolt.
Preferably, the gap (35) on the steel limb plate (23) opens up upwards at corresponding pin (43), and width is gradually
Increase, gap (35) bottom arc radius is matched with pin (43) radius, and gap (35) outer edge is processed into arcuation, both just
It can avoid the influence that stress is concentrated again in installation.
Preferably, for the steel limb plate (23), half is opened up at its flange plate (22) oblique with back-off groove profile part
Circular hole (33), can for nut (45) provide installation space, translate force through weld seam be transferred to back-off groove profile part the edge of a wing (22) after,
It is transferred to the web (21) of back-off groove profile part respectively again, to wearing bolt (42) or continuous rod part (2).
Preferably, it is opened up with discontinuous rod part (1) end at flange plate (22) contact surface of back-off groove profile part
Convenience is provided for installation with space needed for providing nut (45) with the matched chamfered groove of nut (45) size (131 and 132),
Chamfered groove (131 and 132) Wei " ∟ " shape, two discontinuous rod parts (1) in continuous wooden rod piece (2) side connect, two chamfered grooves
(132) " Contraband " shape space is synthesized；Chamfered groove (131) is located at groove (14) side, constitutes with the section of groove (14) other side
" Contraband " shape space.
Preferably, the pin hole (15 and 16) opened up on the discontinuous rod part (1) need not penetrate, and make discontinuous rod
The one side of part (1) can't see pin, part timber holding continuity that is not only beautiful but also can making rod part (1).
Beneficial effects of the present invention are as follows: position of joints steel using amount is less, light weight, relatively inexpensive；Node connection type
Two kinds are connected with pin including being bolted, the edge gap (35) of steel limb plate (23) facilitates installation to position, and applies suitable for assembled
Work；Steel exposed face is small, sees that the complete wooden atmosphere of presentation, appearance neat appearance can also reduce the fire prevention of steel anti-corrosion and apply from bottom to top
The dosage of material, cost-effective and environmentally friendly；Special section connector (3) is integrated in factory process in advance, it is ensured that connector quality,
And it is convenient for assembled in situ；The present invention effectively makes rod part (1,2) and special section connector (3) fit together collaboration work
With node bending resistance and shearing resistance effect are preferable；Steel limb plate (3) and discontinuous rod part (1), the web (21) for being buckled to groove profile part with
Continuous wooden rod piece (2) connection is all made of pin connection, and timber is completely embedded with pin, can effectively play the combination of timber and steel
Effect.
