Description

A kind of steel box assembly reaches and makes up U-shaped beam by its steel case-concrete of forming
Technical field
The utility model relates to the girder construction in the building field, particularly relate to a kind of steel box assembly, also relate to steel case-concrete of being formed by this steel box assembly and make up U-shaped beam, can be used as and be applied to that bearing capacity is big in bridge, industrial construction, the civilian construction structure, span is big, the restricted beam of section area.
Background technology
Steel framed concrete beam comprises shaped steel-concrete beam, steel case-concrete beam etc., wherein, shaped steel-concrete beam refers to dispose in the concrete structure of rolled section steel or welding shaped steel and reinforcing bar, as shown in Figure 1, steel case-concrete beam 30 refers to: be welded into the beam that cross section is square or rectangle with steel plate, concrete perfusion and configuration reinforcement in the confined space of beam when steel case-concrete beam 30 is used as floor beam, directly are fixed on the lower face of floor 40.Steel framed concrete beam has the characteristic of steel work and reinforced concrete structure concurrently, can bring into play the high and high advantage of concrete crushing strength of steel tensile strength simultaneously, at present, steel framed concrete beam has been widely used in the industrial construction field as the conversion beam of heavy load beam, crane girder, highrise building, big load beam.
But also there are following defective in existing shaped steel-concrete beam, steel case-concrete beam:
⑴ compare with reinforced concrete beam, and the steel using amount of existing shaped steel-concrete beam is more, and not only from great, and the amount of expending of steel is more.
⑵ existing steel case-concrete beam is when construction, need be to fluid concrete in the airtight rectangle steel case cross section, it is big to build difficulty, concrete perfusion leakiness, the phenomenon not in place of vibrating appear easily, then influence steel plate and the friction between the concrete, interlock effect and the binding ability of the two of steel case, thereby influence the bearing capacity of beam.
⑶ at the negative moment area of existing shaped steel-concrete beam, the maximum section of general hogging moment is the bearing place at beam two ends, there is the pressurized stable problem in the shaped steel that is positioned at the below, stable in order to guarantee pressurized, tend to set up side direction drawknot parts, such as angle brace or pull bar etc., this just makes structure more complicated, also can influence the building instructions for use sometimes.
⑷ have now on the lower face of the shaped steel fixing concrete floor in shaped steel-concrete combination beam, shaped steel except the upper surface of top flange with concrete contacts, outside all the other each surfaces all are exposed to, therefore exposed parts is more, anticorrosion fire area is also corresponding bigger, cause disposal cost higher, cost increases; There is such problem too in steel case-concrete beam.
⑸ the work progress of existing compound beam generally need be built construction formwork earlier, and then fluid concrete again with the construction formwork dismounting, has so not only increased construction cost, but also prolonged the construction period afterwards to form compound beam.
