Description
Technical field
The utility model belongs to the building operations technical field of structures, is specifically related to a kind of floor steel truss structure.
Background technology
At present, in building structure floor technical applications, it is several that the type of floor mainly contains cast in place concrete plate, concrete prefabricated board, superimposed sheet, composite deck slabs etc.Along with highrise building, the particularly development of high-rise building steel structure, composite floor more and more is subject to people's attention, also more and more higher to the requirement of floor steel truss.Truss is generally the supporting traverse structure be formed by connecting by welding, riveted joint or bolt by rod member, and sufficient intensity need to be arranged, not fracture or plastic strain; Enough rigidity are arranged, excessive elastic deformation does not occur; Enough stability is arranged, do not occur to cause caving in because of the sudden transition of equilibrium form; Good dynamics, antidetonation, wind resistance.
People are a lot of to the research of floor steel truss structure, such as: the Chinese patent that application number is 200620102302.0 discloses a kind of large span combined truss, there is the structural member that two Pin consist of upper chord, web member and lower chord combination, the upper chord of described two structural members is parallel to each other and an alternate distance, between described two upper chords that are parallel to each other across being associated with precast plate.And for example: the Chinese patent that application number is 200620106053.2 discloses a kind of steel truss, be provided with lower chord, be associated with " V " shape web member on lower chord, " V " shape web member upper end is associated with shearing-resistant member, and the shearing-resistant member side opening is provided with for connecting the perforation of tool-type upper chord.But the direction of people's Improvement is improved mainly for intensity, rigidity and the construction facility of steel truss, but seldom its antidetonation, wind resistance is considered.
In recent years, the various places earthquake occurs frequent, and house caves in, and people's security of the lives and property is on the hazard, and is badly in need of this is found to corresponding measure.The floor steel truss structure of developing higher antidetonation, wind resistance has been extremely urgent task.
Summary of the invention
The purpose of this utility model is for the problems referred to above, and a kind of floor steel truss structure is provided, and has excellent anti-seismic performance and wind resistance, and simple in structure, easy for installation, and saving steel reduces cost, and speed of application is fast, saves template.
For achieving the above object, the technical solution adopted in the utility model is: the floor steel truss structure, comprise upper chord, web member and lower chord, described web member comprises diagonal web member and straight web member, described diagonal web member comprises span centre diagonal web member and two ends diagonal web member, described straight web member comprises the straight web member of the straight web member of span centre and two ends, the straight web member of the straight web member of described span centre and described two ends is located between described upper chord and described lower chord, described two ends diagonal web member mitered is between described upper chord and described lower chord, described span centre diagonal web member surrounds diamond structure, be provided with at least two described diamond structures between described upper chord and described lower chord.When earthquake occurs, the maximum moving internal force of span centre surpasses the truss at two ends, particularly large span, and the web member structure of span centre need to meet higher shockproof requirement, therefore need to carry out special design to the web member of span centre.Whole vertical loads, wind that diamond structure can be born superstructure carry and seismic load, and intensity and space stiffness superior, when earthquake occurs, can play good cushioning effect, shake-proof ability is greatly enhanced.A plurality of diamond structures are a plurality of positions damping vibration and moving internal force spatially, further strengthens shake-proof ability.

As preferably, described a plurality of diamond structures are along laterally or vertical array.Can directly be connected with top on top between a plurality of diamond structures, or be connected by horizontal or vertical straight-bar.
As preferably, described a plurality of diamond structures are all mutually vertical at same plane or plane, place.A plurality of diamond structures are at same plane damping vibration repeatedly, the plane, place mutually vertically can be on multiple directions damping vibration.
As preferably, described two ends diagonal web member forms " W " shape structure, or described two ends diagonal web member and described two ends straight web member formation " K " shape structure.The two ends diagonal web member coordinates the span centre diagonal web member to play better shockproof, protection effect.
As preferably, described two ends diagonal web member forms serpentine configuration.Serpentine configuration is similar to the loop configuration of spring, spatially has flexible very strong characteristics, has good shockproof effect, coordinates the straight web member in two ends, and the upper strata floor is had to good supporting role.
As preferably, described lower chord two ends are provided with shelves bar.For being shelved on load bearing wall or girder.
As preferably, between described upper chord and straight web member, be provided with shearing-resistant member.Make the shear resistance of truss more excellent.
As preferably, be provided with prefab form above described upper chord.Top arranges the prefab form of various functions, is applicable to the composite floors such as various cast-in-place, die moulds, installation, and construction is convenient.
The utility model discloses a kind of floor steel truss structure, there is excellent anti-seismic performance and wind resistance, and simple in structure, easy for installation, saving steel, reduce cost, speed of application is fast, saves template, is fundamentally solving a lot of drawbacks of floor steel truss structure of the prior art, there is revolutionary meaning, will have a good application prospect in the building operations technical field of structures.
