Detailed description of the invention
With reference now to accompanying drawing, describe embodiment of the present utility model, element numbers similar in accompanying drawing represents similar element.As mentioned above, as illustrated in fig. 1 and 2, steel-concrete-steel that the utility model embodiment provides is combined crashproof, blast resistant construction component, comprise: steel plate layer 1, concrete 2, shearing-resistant member 3, backing plate 4 and high-strength epoxy resin binder 5, described shearing-resistant member 3 is fixed by described weld seam 6 with described backing plate 4, described backing plate 4 binds fixing by described high-strength epoxy resin binder 5 and described steel plate layer 1, described concrete 2 is built between described steel plate layer 1 in upside and the described steel plate layer 1 in downside, described concrete 2 is by described shearing-resistant member 3, backing plate 4 and high-strength epoxy resin binder 5 seal coated.
In an embodiment, the rectangular array of described shearing-resistant member 3 is located between the described steel plate layer 1 in upside and the described steel plate layer 1 in downside.
In an embodiment, the shape of described backing plate 4 is circular or rectangle.
In an embodiment, described shearing-resistant member 3 is peg or reinforcing bar or shaped steel.
In an embodiment, when using high-strength epoxy resin binder, described steel plate layer 1 and described backing plate 4 all need polishing.
Below the utility model steel is described, forming step that tensile connecting structure is held concurrently in the shearing resistance of concrete mixed type and operating principle:
As illustrated in fig. 1 and 2, the utility model comprises six parts, and after shearing-resistant member 3 and backing plate 4 are shaping in advance by welding, recycling high-strength epoxy resin binder 5 and steel plate layer 1 are binded, and finally build shaping by concrete 2.
Shearing-resistant member 3 and backing plate 4 welding fabrication in advance, then directly realize steel-steel by high-strength epoxy resin binder 5 and steel plate layer 1 and bind, last placing of concrete 2.Component is when pressurized, and steel plate layer 1 and concrete 2 will to horizontal direction dilatancies, and tension is stoped steel plate layer 1 lateral deformation by shearing-resistant member 3, fills concrete 2 owing to being subject to the effect of contraction of steel plate layer 1 by three dimension stress in steel plate layer 1, and concrete 2 compressive strength improves; Due to the existence of backing plate 4, be equivalent to the thickness adding outer steel plate layer 2, the flakiness ratio thus can slow down reducing plate even avoids the generation of cripling after steel plate layer 1 pressurized, improves steel plate layer 1 compression bearing simultaneously; Thus improve the compression bearing of Integral combined structure.Component as beam, board member by curved time, shear stress on interface between steel plate layer 1 and concrete 2 is born by cohering between backing plate 4 and steel plate layer 1, as long as guarantee that binding strength exceedes the shear-carrying capacity of shearing-resistant member 3, then can control and reduce the Relative sliding between steel plate layer 1 and concrete 2, delay beams and slabs crack to occur, the failure mode of component changes lower floor's steel plate layer 1 into be surrendered or concrete compression destruction, thus plays material property.
As shown in Figure 3, combined crashproof, the blast resistant construction component of the utility model steel-concrete-steel can be set as domes, and form steel-concrete-steel built-up arch, and two ends are all sealed by liner plate 7, described liner plate 7 is welded on described steel plate layer 1 two ends.Steel-concrete-steel built-up arch has arching, and compressive property is strong, has the feature of bearing capacity, can be used for the structures such as anti-icing wall, anti-collision wall, blast wall.
In an embodiment, described steel plate layer 1 is double-decker.Steel-concrete-steel built-up arch uses double-layer plate, can cancel template during concrete perfusion, improves efficiency of construction, and can be prefabricated in batches.
Steel-concrete-steel built-up arch can prevent seepage when being used for oil storage tank, and surface stops water body infiltration.
Steel-concrete-steel built-up arch anti-water-stop body, ice raft can wash away the destruction of inner concrete.
Steel-concrete-steel built-up arch can prevent excessive shock local distortion, inside fills concrete and can absorb the energy impacting and cause.
Steel-concrete-steel built-up arch is poured into light high strength concrete, and weight comparatively conventional steel bar concrete structure alleviates greatly, convenient transportation.
Steel-concrete-steel built-up arch can change ice body structural deterioration pattern, is destroyed become bending failure from conquassation, thus greatly reduces the overall ice loading acting on structure.
Steel-concrete-steel built-up arch can with the quantity of less steel plate ribbed stiffener and welding, and the use of compound section will reduce steel using amount.
Composition graphs 1-3, because the utility model adds backing plate 4, the flakiness ratio thus can slow down reducing plate even avoids cripling problem after steel plate layer 1 pressurized, bearing power increase; Bind with high-strength epoxy resin binder 5 between backing plate 4 and steel plate layer 1, will welding capacity be reduced, improve integrally-built anti-fatigue performance; Precast construction plate is without height restriction; Error after assembling between plate is little; The concrete 2 filled in can giving when pressurized provides effect of restraint, thus improves integrally-built Compressive Performance.
Above disclosedly be only preferred embodiment of the present utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
