Abstract
The invention discloses a method for designing a steel reinforced concrete beam template bracket based on a synergetic stress theory. According to the method, the steel reinforced concrete load is supported by a lower beam template bracket and an inner beam steel framework by adopting a template bracket stress method based on the synergetic stress theory of a steel reinforced concrete beam and a template bracket system of the steel reinforced concrete beam. The load of the template bracket is reduced and distributed, the material performance is made full use of, the material consumption and the construction difficulty are reduced, and the economic benefits are increased.
Description
Technical field
The present invention relates to technical field of building construction, be specifically related to a kind of girder with rolled steel section en cased in concrete falsework method for designing based on the cooperative bearing theory.
Background technology
Method for designing for the girder with rolled steel section en cased in concrete falsework, normally with reference to the method for designing of conventional steel Concrete Beam Reinforced falsework, whole steel concrete loads is all born by falsework, the problem that the method exists is: the steel concrete load is larger in the girder with rolled steel section en cased in concrete, it is too much overstocked to calculate the vertical rod of beam lower carriage by conventional method, increase difficulty of construction, improved engineering cost.
Girder with rolled steel section en cased in concrete is generally used for high-rise Super High labyrinth or conversion layer structure, beam section is relatively large, if the method for designing according to the conventional steel tendon concrete structure, load is larger, the vertical rod number needs will roll up under the corresponding beam, cost of materials and labour cost be corresponding increase all, and traditional design method is ignored the supporting capacity of girder with rolled steel section en cased in concrete inner steel frame in practice of construction simultaneously, has caused the waste of material property.
Summary of the invention
Technical problem to be solved by this invention is: a kind of girder with rolled steel section en cased in concrete falsework method for designing based on the cooperative bearing theory is provided, solve the falsework system of girder with rolled steel section en cased in concrete in the excessive situation of Load value, the falsework large usage quantity, the waste material, difficulty of construction is large, the problem that construction cost is high.
The technical scheme of technical solution problem of the present invention is: adopt the stressed method of falsework of girder with rolled steel section en cased in concrete and falsework system cooperative bearing theory thereof, with the steel concrete load by type steel skeleton shared in beam lower bolster support and the beam.
The invention has the beneficial effects as follows: falsework is born reduction of live load distribute, take full advantage of material property, reduce material usage and difficulty of construction, improved economic benefit.
The specific embodiment
The present invention is described in more detail below in conjunction with embodiment.
Embodiment 1
(1) theoretical according to girder with rolled steel section en cased in concrete and falsework system cooperative bearing thereof, try to achieve type steel skeleton and in work progress, bear steel concrete load combination ratio coefficient μ;
(2) theoretical according to cooperative bearing, factor of proportionality μ is incorporated in the Load Combination of falsework calculation on Construction project computational item Load Combination and calculate conventionalloading and see Table 1 and table 2;
(3) load after the optimal design is assigned to each computational item, according to the related specifications of falsework design, carries out the falsework Optimal design and calculation.
The conventional floor-type support method of table 1 calculation on Construction project and relevant Load Combination
| Computational item | Relevant Load Combination load |
| The type steel skeleton Force Calculation | G 1k+μ(G 2k+G 3k) |
| Beam bottom mother plate calculates | (1-μ)(G 2k +G 3k)+ G 4k +Q 1k |
| Side template calculates | Q 2k+Q 3k |
| Falsework calculates | (1-μ)(G 2k +G 3k)+ G 4k + G 5k+Q 1k |
Table 2 calculates conventionalloading
The above is not to be limitation of the present invention, and every technical solution of the present invention content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment does, still belongs to the protection domain of technical solution of the present invention according to technical spirit of the present invention.
