Background technology
Along with the development of society, the progress of science and technology, people have higher requirement for the traffic environment of life, live in peace house, office conditions etc.And as the builing industry of the above-mentioned environment of building, then assume responsibility for sizable a part of responsibility, especially at rapidly and efficiently safe construction, and ensure the high-quality a large amount aspect of building.
Steel reinforced concrete combining structure a kind ofly shaped steel is imbedded the combining structure formed in steel concrete, and it is large that this structure has rigidity, and supporting capacity is high, the feature that fire resistance is good.But be furnished with the i iron of steel plate processing and fabricating in steel reinforced concrete combining structure, channel-section steel, H profile steel and cross-shaped steel, complex manufacturing technology, technical requirement is high, simultaneously, because the price of steel is relatively high, smelt shaping energy consumption higher, cause steel reinforced concrete combining structure cost higher and unsustainable development, more because inner steel work and external wrapping concrete are dissimilar materialss, the bonding surface place of the two, there is folder gap, the defects such as hole, in particular surroundings, corrosion can be there is and form the swollen effect of rust in inner shaped steel, this effect can sell the cementation of weak external wrapping concrete and inner shaped steel further, " sharing lood " of steel reinforced concrete combining structure is acted on and is difficult to abundant realization, also structure is made not reach supporting capacity needed for design point and rigidity.
Summary of the invention
In order to overcome above-mentioned deficiency of the prior art, the utility model provides this one to utilize RPC (RPC:Reactive Powder Concrete) material to make real abdomen skeleton to carry out alternative steel frame, avoid the above-mentioned shortcoming of reinforced concrete composite structure, the design of innovative combination structure, promotes the greenization of structure and the steel flanged beam RPC skeleton-concrete combined structure of sustainability.
The purpose of this utility model is achieved in that
Steel flanged beam RPC skeleton-concrete combined structure, comprises RPC skeleton 1, and it is outer by longitudinal reinforcement 3 and the steel mesh reinforcement that formed fixing with circumferential reinforcement 4 that bag is attached to RPC skeleton 1; And to be filled between RPC skeleton 1 and to wrap the concrete 2 of attached steel mesh reinforcement between RPC skeleton 1 and steel mesh reinforcement;
Described RPC skeleton 1 is cross-shaped configuration;
The construction technology of described steel flanged beam RPC skeleton-concrete combined structure, its concrete steps are as follows:
The first step: by the preparation principle of RPC, makes RPC skeleton 1, and founds RPC skeleton 1 forming panel at factory's frame, lays anchor bar, build RPC, prefabricated RPC skeleton 1, and press Maintenance Mechanism, maintenance to 28 day at RPC skeleton 1 two ends;
Second step: by RPC skeleton 1 hoisting transportation that is prefabricated in the factory in the first step to building site, frame founds skeleton, and make anchor bar anchor reserved in skeleton in basis or existing bean column node, after location and installation, make RPC skeleton 1 bear integrally-built first phase dead load and working load;
3rd step: after completing second step work, outside RPC skeleton 1, by designing requirement, frame shuttering 5, builds ordinary concrete 2, and maintenance is to the intensity of regulation;
4th step: folding mould, makes RPC skeleton 1 and outsourcing ordinary concrete sharing lood, bear first and second phase dead load and the service load of building structure.
positive beneficial effect:the utility model adopts RPC to replace conventional metal material as the main material of skeleton, and overcome the inevitable etching problem of metal material, substantially increase the durability of skeleton concrete structure, cost have also been obtained control simultaneously; The homogeney of RPC and ordinary concrete, decreases the reality beginning defect at the bonding surface place of skeleton and external wrapping concrete, increases the density of structure, improves RPC skeleton-concrete combined structure holistic resistant behavior; When equal bearing capacity, RPC has lower energy consumption and lower price than steel, and RPC skeleton-concrete combined structure is more green than steel reinforced concrete combining structure, more economical, more sustainable development; RPC skeleton can according to engineering practice, and be made as I shape, grooved, H type and cross easily in advance, manufacturing technology index is low, and technique is simple; Steel flanged beam RPC skeleton-concrete combined structure applied range, cost is lower, easily applies.

Detailed description of the invention
Below in conjunction with accompanying drawing, contrast the utility model is described further:
As Figure 1 and Figure 4, steel flanged beam RPC skeleton-concrete combined structure, comprises RPC skeleton 1, and it is outer by longitudinal reinforcement 3 and the steel mesh reinforcement that formed fixing with circumferential reinforcement 4 that bag is attached to RPC skeleton 1; And to be filled between RPC skeleton 1 and to wrap the concrete 2 of attached steel mesh reinforcement between RPC skeleton 1 and steel mesh reinforcement;
Described RPC skeleton 1 is cross-shaped configuration;
The construction technology of described steel flanged beam RPC skeleton-concrete combined structure, its concrete steps are as follows:
As shown in Figure 2, the first step: by the preparation principle of RPC, makes RPC skeleton 1, and found RPC skeleton 1 forming panel at factory's frame, lay anchor bar at RPC skeleton 1 two ends, build RPC, prefabricated RPC skeleton 1, and press Maintenance Mechanism, maintenance to 28 day;
