Abstract
A large-span beam connecting structure made of composite materials or composite lumber comprises a left beam (1) and a right beam (2) made of composite materials or composite lumber to be connected. The structure is characterized in that slots (3) are processed at the middle parts of the end surfaces where the left beam (1) and the right beam (2) are butted, both ends of a connecting piece (4) are respectively inserted in the slots (3) at the ends where the left beam (1) and the right beam (2) are butted, a through-hole (6) penetrating through a corrosion-proof metal screw rod or a screw rod (5) made of composite materials is formed on the connecting piece (4), and the connecting piece (4) is positioned at the end parts of the left beam (1) or the right beam (2) through the corrosion-proof metal screw rod or the screw rod (5) made of composite materials. The structure has the advantages of simple structure and reliable connection.
Description
Technical field
The utility model relates to a kind of building structure, especially a kind of syndeton of long-span beams, specifically a kind of composite material or composite wood long-span beams syndeton.
Background technology
As everyone knows, in heavy construction such as sports palace, large-scale exterior decoration engineering, industrial chemicals warehouse, club etc. are owing to need long-span beams to support, and this type of beam at present the most frequently used be metal steel structure, just adopted typical steel structure girder as the Bird's Nest of one of Beijing Olympic venue.But steel structure girder weight is big, difficulty of construction is big, especially need to carry out corrosion-resistance treatment, therefore cost is very high, especially coastal area, because salt content is big in the air, the easier Corrosion of Metallic Materials that causes, as adopt stainless steel, then increase difficulty and cost more, for this reason, people have expected utilizing composite material to replace steel to build large-scale building, and series of advantages such as composite material or composite wood are wide, in light weight owing to the raw material source, good corrosion resistance are as the alternative material of using of the first-selection of steel.Its not only alternative steel, and can substitute solid wood and be used for all kinds of buildings and use as beam column.
Because the characteristics of the timber of composite material manufacturing have determined it to be weldingly connected as steel, can not as solid wood, connect to satisfy the needs of long-span beams by tenon, therefore must be according to the syndeton of the characteristics design specialized of composite material or composite wood, both satisfied the requirement of bonding strength, life requirement, requirement attractive in appearance guarantees the requirement that easy construction and cost are low again.
Summary of the invention
The purpose of this utility model is the characteristics at composite material or composite wood, designs a kind of composite material or composite wood long-span beams syndeton to satisfy the needs of construction work.
The technical solution of the utility model is:
A kind of composite material or composite wood long-span beams syndeton, comprise the composite material or composite wood left side beam 1 and composite material or the right beam 2 of composite wood that need connection, it is characterized in that the end face middle part that described left beam 1 and right beam 2 connect all is processed with slot 3, the two ends of connector 4 are inserted left beam 1 and right beam 2 respectively and are connected in the slot 3 of an end, described connector 4 is provided with the through hole 6 that installs corrosion resistant metal screw rod or composite material screw rod 5, and connector 4 is positioned at the end of left beam 1 or right beam 2 by described corrosion resistant metal screw rod or composite material screw rod 5.
Described connector 4 is corrosion resistant metal connector or composite material connector, is convex structure around the described connector 4.
Two rows, the above or ring through hole 6 of two rows are established in the center line both sides of described connector 4 upper edge short transverses.
Described through hole 6 is a mounting hole.
One side of described connector 4 is connected with collet 7, and the length of collet is the distance of connector 4 left and right sides arc breakpoints.
Described left beam 1 and right beam 2 are all straight beam or are all curved beam.
The beneficial effects of the utility model:
The utility model has solved the connection difficult problem of large span composite material or composite wood, for replacing steel and solid wood to pave road with composite material or composite wood, and makes it to become possibility.
Syndeton of the present utility model can be widely used in all kinds of large-scale stadiums such as indoor swimming pool and various venue that large span connects, club, the Corrosive Materia warehouse etc. of needing, and is particularly suitable for the construction of coastal seriously corroded area large stadium.
Of the present utility model simple in structure, load-bearing and shock resistance are good, and especially the design of this connector circular arc chamfering has improved the antidetonation bearing capacity of connected node greatly.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 1-8.
A kind of composite material or composite wood long-span beams syndeton, comprise that the composite material or the composite wood left side beam 1 that need to connect (can be square beam or circular beam, can adopt the prior art manufacturing, customization or directly from market purchasing) and composite material or composite wood right side beam 2 (can be square beam or circular beam equally, can adopt the prior art manufacturing, the customization or directly from market purchasing), left side beam 1 and right beam 2 can be curved beam shown in Figure 1, also straight beam, the end face middle part that described left beam 1 and right beam 2 connect all is processed with slot 3, as Fig. 2, the two ends of connector 4 are inserted left beam 1 and right beam 2 respectively and are connected in the slot 3 of an end, described connector 4 is provided with the through hole 6 that installs corrosion resistant metal screw rod or composite material screw rod 5, and connector 4 is positioned at the end of left beam 1 or right beam 2 by described corrosion resistant metal screw rod or composite material screw rod 5.
During concrete enforcement, also can be connected with collet 7 on the base of connector 4, and the length of collet is the distance of connector 4 left and right sides arc breakpoints.Shown in Fig. 5,6,7,8.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
