Abstract
The invention relates to a combination structure of a tension structure and a cantilever structure and a combining method thereof. The combination structure comprises a tension structure, rigid cantilever structures, a rigid constraint component and a support structure, wherein the tension structure is connected with the rigid cantilever components to form a combination through the rigid constraint component, and the combination is connected to the support structure. The combining method of the combination structure includes: arranging a ring truss or a ring beam inside the rigid cantilever structure to serve as the rigid constraint component, connecting the outer ends of outer-ring ridge cables or outer-ring stay cables of a cable dome structure to the ring truss or the ring beam, providing temporary supports for the rigid cantilever structures during construction, removing the temporary supports after completion of prestress tension of the cable dome structure, and finally forming the stress-balanced combination structure of the cable dome structure and the cantilever structures. The combination structure has the advantages that internal stress balance of the structure system is realized, stress to the ring truss is lowered, and a large space without columns is reserved.
Description
Technical field
The present invention relates to a kind of architectural structure system, particularly relate to combined structure system and the combined method thereof of stretching-drawing structure and rigid structures.
Background technology
Cable dome structure has built up many abroad at present.Cable dome structure is as a kind of large span spatial structure of flexibility, and is different with the general spatial structure, and it mainly provides rigidity by prestressing force.Cable dome structure must be formed a closed-loop path with the pressurized ring beam of periphery, is a kind of self equilibrium systems, and structure has adaptive ability.Therefore existing cable dome structure must arrange special confining part all for the balance internal tension, and such as compression ring truss or ring beam, and confining part such as outside ring beam is often bigger, ability tail rope dome pulling force.
The stretching-drawing structure that the present invention proposes and the combined structure system of rigid structures can combine the inside tensions of stretching-drawing structure such as rope dome, the inner outwards tension of cantilevered structure, are subjected to force self-balancedly inside and outside the realization, reduce the stressed of compression ring truss and ring beam greatly.
Summary of the invention
Technical problem
The bigger structure of span in the middle of encorbelmenting all around is because the part of encorbelmenting makes the inside configuration upper edge produce radially outer pulling force, so internal construction often will be made tension ring beam or ring truss for bearing this pulling force.
Cable dome structure is as a kind of stretching-drawing structure, peripheral notochord and oblique cord outer end need be connected fixed end, generally be the radially inside pulling force that employing pressurized ring beam or the mode of encircling truss are born the inner cable dome, often cause ring truss and ring beam huge, just to bearing rope dome external pull.
Technical scheme
The present invention proposes the combining structure of a kind of stretching-drawing structure and rigid structures, it is characterized in that described combining structure comprises stretching-drawing structure, rigidity cantilevered structure, rigid constraint member and braced structures, described stretching-drawing structure is connected to form assembly by described rigid constraint member and described rigidity overhanging component, and this assembly is connected on the described braced structures.
The present invention proposes the combined structure system of a kind of stretching-drawing structure and rigid structures, it is characterized in that comprising stretching-drawing structure and rigidity cantilevered structure, and both connect by encircling truss or ring beam or other rigid constraint member, and above assembly is connected on the braced structures.
Stretching-drawing structure is preferentially selected cable dome structure for use, also can be the double-deck rope web frame of rung formula, suspended-cable structure, monolayer cable net structure etc.,
Rigid structures can be overhanging steel structure, also can be concrete structure or the combining structure of encorbelmenting.Rigid structures can for one deck or two-layer and more than.Simultaneously, rigid structures also can be the suspended structure system.
The member that connects stretching-drawing structure and rigid structures is ring truss or ring beam or other rigid constraint members.
Cantilevered structure and cable dome structure link to each other by hoop truss or ring beam or other confining parts.
Beneficial effect
By the new combining structure that the present invention proposes, the cantilevered structure part is because radially outer pulling force produces the hoop tension effect to ring truss or ring beam; After cable dome structure prestressed stretch-draw and the carrying, radially notochord and oblique cord tension radially produces the circumferential pressure effect to ring truss or ring beam.Therefore encorbelment part and rope dome at ring truss or ring beam place internal force balance, implementation structure system inside is subjected to force self-balanced, significantly reduces that to encircle truss stressed.Inside can realize not having the post large space simultaneously.
