Description
Technical field
The present invention relates to the Structural Engineering field in civil engineering, specifically a kind of rely on frictional connection after add making and the implementation method thereof of non-principal girder steel and original combined steel and concrete column.
Background technology
Steel reinforced concrete structure refers to a kind of new structure burying shaped steel in steel concrete inside underground.Include shaped steel and can be divided into the large class of steel flanged beam and open web type two, steel flanged beam shaped steel, except employing rolled section steel, can also adopt the steel cross section of Plate Welding, and open web type shaped steel is generally formed by batten plate or lacing connecting angle or channel-section steel.To this structure, differ at country variant call, Japan is referred to as steel-reinforced concrete structure, and the former Soviet Union is referred to as steel composite construction, and China's custom is referred to as steel reinforced concrete structure.This structural advantages is more, and main manifestations is as follows.
1. steel reinforced concrete structure bearing capacity is high, and section area is little.Because steel reinforced concrete structure does not limit by steel ratio, the same shape reinforced concrete structure of its bearing capacity ratio exceeds more than one times.
2. save labour and material.Shaped steel formed steel work before concreting, and it has sizable bearing capacity, can bear live load when member dead weight and construction, and template can be suspended on shaped steel, and need not be template-setup pillar, because this reducing labour and material.
3. shorten the construction period, the multilayer of steel reinforced concrete structure and high level need not wait until that concrete reaches some strength and just can to construct upper strata, therefore shorten the construction period.
4. rigidity and ductility good, steel reinforced concrete structure inside is provided with shaped steel, and the strength and ductility of shaped steel self is better, and shaped steel and surrounding concrete retrain mutually, the two co-operation, therefore than the ductility of reinforced concrete structure and large many of rigidity.
In addition, steel reinforced concrete external wrapping concrete, and concrete densification is hard, impermeability, apyrous and corrosion resistance are all better than steel work.
Owing to having above-mentioned advantage, the application of steel reinforced concrete in China's engineering structures obtains large quantity research and common concern.But prior art is comparatively extensive to combined steel and concrete column and girder steel performance study, studies less to combined steel and concrete column and steel beam joint.Further, along with the raising of building level and the improvement of living standard, the instructions for use of people to building improves constantly.Especially industrial premises and business building, along with the change of purposes, also different to its structural requirement.Industrial premises and the business change of building application target, can cause the change of its spatial framework.At present, researcher participates in combined steel and concrete column and girder steel the effect that building space forms and is mostly positioned building early stage or period, to building completion or after coming into operation, combined steel and concrete column and girder steel participating space are formed does not have intensive research, Gu current engineering circles needs to find a kind of participating space general layout formation after having built and the combined steel and concrete column-girder steel method of attachment not destroying original structure.
Summary of the invention
The object of the invention is for the deficiencies in the prior art, provide a kind of after add the assembling steel reinforced concrete-steel beam joint linkage of non-principal component, this programme construction is comparatively quick, and structure is more reasonable, and does not destroy inhering architecture.The technical scheme of invention is as follows:
A kind of assembling reinforcing bar concrete column-steel beam friction-type node and implementation method thereof, comprise two blocks of stirrup plates, two pieces of U-shaped reinforcing bar arm-ties, prestressed high-strength bolt, frictional high-strength bolts, steel plate strength rib and the end plates with bolt penetration hole.4 block plates are enclosed in outside combined steel and concrete column by prestressed high-strength bolt passing through bolt hole, the prestressing force that high-strength bolt applies is converted into the pressure between stirrup plate and the contact surface of combined steel and concrete column, and combined steel and concrete column is converted into frictional force to the holding power of girder steel by the pressure of contact surface and provides.End plate is fixed on U-shaped steel arm-tie by frictional high-strength bolts, welds afterwards with the shaped steel of girder steel inside.
The width of described stirrup plate is greater than the length of surrounded concrete column, and arranges bolt hole having more in length.
The stiffening rib of described steel plate hoop is rectangle, and length is greater than the size that stirrup plate has more concrete length.
The stiffening rib of described U-shaped steel arm-tie is triangle, is welded on U-shaped steel plate knuckle place, and added triangle strength rib is lucky and knuckle shape is coincide.
The strength of materials of described stirrup plate and U-shaped steel arm-tie and institute's stiffening rib is Q235, Q345 or Q390, and the strength grade of high-strength bolt is 8.8 grades or 10.9 grades.
Described prestressed high-strength bolt and frictional high-strength bolts are furnished with Weir disc spring packing ring.
Preservative treatment will be carried out in described stirrup plate, U-shaped steel arm-tie, rectangle strength rib and triangle strength rib surface, and processing mode is one that is zinc-plated or that spray paint.
Compared with the existing technology, the present invention has the following advantages:
(1) intensity is high, the holding power of girder steel of the present invention is born by the frictional force of stirrup plate and profile steel concrete column contact surface, and when stirrup plate is subject to the pressure that girder steel transmits, constructing apparatus has minor rotation, the effect of contraction of profile steel concrete column to constructing apparatus stops it to rotate, and therefore the pressure of girder steel is frictional force and restraint forces shared.
(2) prestress application process is convenient, because hoop plate containment surfaces is comparatively large, thus decreases the quantity of device, and only on two blocks of stirrup plates and two pieces of U-shaped steel arm-ties, just can complete prestress application process through prestressed high-strength bolt.
(3) with low cost, package unit all adopts steel plate to be formed by connecting, and in addition to screws, do not need other fixtures, processing cost is lower.
(4) safety is high, and this device utilizes the frictional force of combined steel and concrete column and stirrup plate contact surface to bear the pressure of girder steel beam, does not need to destroy building original structure.
