Abstract
The invention belongs to the technical field of structural engineering, and particularly relates to a self-resetting support. The self-resetting support is composed of a reinforced concrete core column, a steel tube sleeve, a pre-stressing tendon and an anchorage device. The reinforced concrete core column is provided with a reserved pre-stressing hole channel which runs through the whole length of the reinforced concrete core column. A pre-embedded connection steel plate joint is arranged at one end of the reinforced concrete core column. One end of the steel tube sleeve is opened, and the other end of the steel tube sleeve is closed, wherein the closed end of the steel tube sleeve is provided with a reserved circular hole for the pre-stressing tendon to pass through, and simultaneously the closed end of the steel tube sleeve is further provided with a connection steel plate joint. The reinforced concrete core column is placed in the steel tube sleeve, and then manufacture of the self-resetting support is completed through the pre-stressing tendon with two ends supporting the reinforced concrete core column in stretch-draw mode. The self-resetting support is simple and convenient to manufacture and install, can return to an initial position after wind, earthquakes and the like horizontally function, and reduces structural residual deformation.
Description
Technical field
The invention belongs to technical field of structural engineering, be specifically related to a kind of Self-resetting and support.
Background technology
Can restore funcitons structure be a kind of novel Aseismic Structure System, be produce under the overall background of color-based image retrieval.Self-resetting structural system is can one in restore funcitons structural system, and this structural system still can get back to initial position after earthquake, and the permanent set of structure or component is very little, then ensure that structure is not collapsed in earthquake, and continues to use.
Being supported in structure Lateral Resistant System is one very important defence line.It is that one makes full use of concrete material pressurized and does very well that Self-resetting supports, the composite support that presstressed reinforcing steel tension should be able to be good.In earthquake, Self-resetting is supported for structure and provides lateral resisting.After geological process, the initial tensile stress of presstressed reinforcing steel enough allows support be returned to initial position, the permanent set of support is dropped to minimum, reduces the residual displacement of structure.
Summary of the invention
The object of the invention is to the deficiency for overcoming existing support and provide a kind of support with self-resetting capability, this support can provide lateral resisting in earthquake, can be returned to initial position again after shake.
To achieve these goals, the technical solution used in the present invention is:
A kind of Self-resetting supports, and comprises steel concrete stem stem, steel pipe sleeve, presstressed reinforcing steel, ground tackle; Wherein:
Described steel concrete stem stem, has the prestressed pore passage of reserved through total length, and there is the second pre-buried plate joint one end of steel concrete stem stem, and the cross section of this second plate joint is T-shaped; The base steel plate of this T-shaped second plate joint is fit together by anchor bar and reinforced concrete core column end, this base steel plate has circular hole, passes for presstressed reinforcing steel; Junction steel plate vertical with base steel plate in this T-shaped second plate joint has some bolts hole, and this bolt hole is used for being connected with external component or main structure body;
Described steel pipe sleeve, is nested in outside steel concrete stem stem; The one end open of this steel pipe sleeve, the other end is remained silent, and one end end face of remaining silent has circular hole, passes through for presstressed reinforcing steel; There is the first plate joint one end of remaining silent of steel pipe sleeve, and this first plate joint is vertical with the end face of remaining silent of steel pipe sleeve, has some bolts hole above, and this bolt hole is used for being connected with external component or main structure body;
The circular hole aligned in position of remaining silent on the base steel plate of circular hole, the reserving hole channel of concrete-core column and T-shaped second plate joint of steel concrete stem stem one end on the end face of one end of steel pipe sleeve, described presstressed reinforcing steel passes duct and the circular hole of these correspondence positions, by ground tackle anchoring after tensioned prestressing bar.
In the present invention, described presstressed reinforcing steel is soap-free emulsion polymeization low relaxed prestress muscle.
In the present invention, the prestressed pore passage of through total length reserved in described steel concrete stem stem, is generally 4, is distributed in the four corners position of steel concrete stem stem.
Self-resetting support manufacturing of the present invention, install simple and convenient, can initial position be returned to after the horizontal force such as strong wind, earthquake, reduce the permanent set of structure.This Self-resetting supports and can be widely used in engineering structures, when geological process, can provide lateral resisting effect, at post earthquake recovery to original state, can change simple and fast again simultaneously.Simple structure of the present invention, easy construction, is conducive to carrying out and applies on a large scale.

Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the present invention will be further described.
For Fig. 1, Self-resetting of the present invention supports, and it comprises steel concrete stem stem, steel pipe sleeve, soap-free emulsion polymeization low relaxed prestress muscle, ground tackle.Steel concrete stem stem 4 with pre-buried second steel plate knot joint 6 is prefabricated to be completed, and steel pipe sleeve 3 factory process with the first plate joint 1 completes.Concrete-core column 4 is placed in the steel pipe sleeve 3 just can laying it.Then soap-free emulsion polymeization low relaxed prestress muscle 2 is passed the duct of steel concrete stem stem 4 inside and the circular hole of steel pipe sleeve 3 closed end, tensioned prestressing bar 2.After stretch-draw completes, good with ground tackle 5 anchoring.Support two ends jointing was finally used to support the position being arranged on needs.
Above-mentioned is can understand and apply the invention for ease of those skilled in the art to the description of embodiment.Person skilled in the art obviously easily can make various amendment to these embodiments, and General Principle described herein is applied in other embodiments and need not through performing creative labour.Therefore, the invention is not restricted to embodiment here, those skilled in the art are according to announcement of the present invention, and the improvement made for the present invention and amendment all should within protection scope of the present invention.
