Abstract
The utility model belongs to a kind of for steel lattice column and the inverse shearing resistance construction made concrete structural beams and connect of pattern foundation pit supporting structure field, and technical solution is：In contrary sequence method foundation pit supporting project, the inverse vertical support structure for making concrete structural beams that the steel lattice column constructed in advance is constructed after being welds shearing resistance steel on the outside of surrounding of the steel lattice column with the inverse intersection for making concrete structural beams.The utility model is simple and reliable, is enhanced with the inverse connection for making concrete structural beams to improve shear-carrying capacity by welding shearing resistance steel in steel lattice column side.
Description
Technical field
The utility model belongs to pattern foundation pit supporting structure field, more particularly to one kind is connect for steel lattice column with inverse concrete structural beams of making
Connecting structure, can be widely used in the contrary sequence method foundation pit supporting project using steel lattice column and concrete structural beams.
Background technology
With the acceleration of Urbanization in China and underground space development, hypogee area is also increasing, excavates deep
Degree is constantly deepened, and pattern foundation pit supporting structure mode is constantly brought forth new ideas, and contrary sequence method utilizes master in base pit engineering supporting by more use, contrary sequence method
Body horizontal structure is as support, and rigidity is big, exempts to tear support open, and being particularly suitable for surrounding enviroment has the foundation pit work of strict protection requirement
Journey.Steel lattice column is generally arranged as vertical support structure in concrete structural beams position in contrary sequence method, therefore makees concrete structural beams inverse
The shear resistance for taking measures to improve reinforced concrete beam column node is generally required between steel lattice column, reinforcement is inverse to make main body steel
The anchoring of reinforced concrete bean column node can improve the constraint factor of node beam, it is ensured that beam-to-column joint stress is safe and reliable.
Utility model content
Connect for steel lattice column and inverse concrete structural beams of making the technical problem to be solved by the utility model is to provide a kind of
The shearing resistance construction connect, it is simple and reliable, enhanced and the inverse company for making concrete structural beams by welding shearing resistance steel in steel lattice column side
It connects to improve shear-carrying capacity.
In order to solve the above technical problems, the basic technical scheme of the utility model is：In contrary sequence method foundation pit supporting project,
Construction steel lattice column in advance, the inverse vertical support structure for making concrete structural beams of constructing after steel lattice column is used as, steel lattice column with
Welding shearing resistance steel enhance and the inverse connection for making concrete structural beams on the outside of the inverse surrounding for making concrete structural beams intersection, improve shearing resistance
Ability.Shearing resistance steel can be angle steel or channel steel, and specification, spacing and quantity can be determined according to practical engineering calculation result.
The utility model by steel lattice column side weld shearing resistance steel come enhance with the inverse connection for making concrete structural beams from
And shear-carrying capacity is improved, which has good shear behavior, easy for construction, highly practical.
Description of the drawings
The utility model will be further described with example and application construction method below in conjunction with the accompanying drawings.
Fig. 1 is the elevational schematic view of the utility model.
Fig. 2 is the vertical view of the utility model.
Specific implementation mode
The utility model by steel lattice column side weld shearing resistance steel come enhance with the inverse connection for making concrete structural beams, carry
High shear resistance.In conjunction with attached drawing, it is described in detail below：As shown in Figure 1, it makees concrete structural beams 1, steel lattice column 2, shearing resistance comprising inverse
Steel 3；In contrary sequence method foundation pit supporting project, steel lattice column 2 of constructing in advance, construction is inverse after steel lattice column 2 is used as makees concrete knot
The vertical support structure of structure beam 1, the welding shearing resistance steel 3 on the outside of steel lattice column 2 and the inverse surrounding for making 1 intersection of concrete structural beams
To enhance and the inverse connection for making concrete structural beams 1, raising shear resistance.Shearing resistance steel can be angle steel or channel steel, specification, spacing and
Quantity can be determined according to practical engineering calculation result.
The scheme provided practical to the utility model is discussed in detail above, for those of ordinary skill in the art, according to
According to the thought of the utility model embodiment, there will be changes in the specific implementation manner and application range.In conclusion this
Description should not be construed as a limitation of the present invention, and any changes made according to the design concept of the utility model are all
It is within the protection scope of the utility model.
