Description

A kind of steel bar girder plate end connects steel structure girder node structure
Technical field
The utility model relates to concrete structure architecture construction fields, specifically, being related to a kind of steel bar girder plate end Connect steel structure girder node structure.
Background technique
Horizontal structure form work engineering in China's building trade generallys use at present sets up bent-frame bracing, additionally arranges flitch and glue Plywood or template.Its technological principle provides support by setting bent-frame bracing system for floor support plate, meets construction stage bearing capacity And deformation requirements.Since that process is tedious is complicated for bent-frame bracing system, basement process need to be carried out, scaffold is set up, installation template, ties up Wire-tie, concrete casting, maintenance, demoulding will occupy a large amount of time, occupy the duration, and the management of leasing of scaffold takes With height, there is also the danger of high-altitude construction.
In recent years, the application with steel construction in building field is goed deep into, and applies the floor support plate between steel structure girder It is laid with and production efficiency is still seriously affected using traditional approach.Chinese Patent Application No.: 2010106235093, patent name: Steelframe truss floor support plate construction method, disclose by by the galvanized sheet of zinc-plated bed die floor support plate and steel bar truss welding in steel knot The mode of structure beam solves the problems, such as bent-frame bracing system, reduces template, scaffolding work, reduces steel bar girder binding Amount.But zinc-plated bed die steel bar girder is at high cost, it is secondary to whitewash relatively difficult, and the segmentum intercalaris of zinc-plated template and steel structure girder Point structure processing is more difficult.
Chinese Patent Application No.: 2013102995081, patent name: self-bearing type bar frame gang form and its construction Method discloses the bar frame of a kind of multiple rows of longitudinal reinforcement truss and multiple rows of transversely distributed steelbar composition, bar frame and can Disassembly template is implemented in combination with few Construction of Supporting scheme of the template in concreting, scaffold when reducing horizontal structure construction It uses.Allow template that utilization is repeated, reduce cost, facilitate secondary powdering, but is applicable only on frame beam structure, Rarely has the application on steel structure girder, and bar frame gang form handling is relatively difficult, and the bar frame of large area Gang form installs node complexity, and bonding strength is low, and load-bearing capacity is weaker.
Summary of the invention
The content of the utility model is to provide a kind of steel bar girder plate end connection steel structure girder node structure, can be real Existing steel bar girder and reinforcing steel bar frame are set a roof beam in place the construction efficiency of higher bonding strength and more efficient, while reducing supporting element significantly Use.
A kind of steel bar girder plate end according to the present utility model connects steel structure girder node structure, including steel structure girder and It is respectively arranged on the steel bar girder plate of steel structure girder two sides, which is characterized in that the floor support plate side detachably connects with steel bar girder It connects, the other side is arranged at intervals with supporting element, the supporting element stretching floor support plate;
For the steel bar girder lapping ends on steel structure girder, the steel bar girder end is welded with supporting rib, the building Board upper surface is suitable with the faying surface height of steel structure girder.The detachable steel bar girder plate of the utility model is using small area scene Assembled method, so that the handling and assembly of steel bar girder plate are all more convenient simple, and single steel bar girder plate assembly is complete Achievement is solderable to fix, therefore node structure is fairly simple and is connected firmly, and is not necessarily to or reduces the supporting frameworks such as scaffold Support, can be constructed with layer stereo, greatly improve construction efficiency, reduce the duration;Pass through supporting element between adjacent steel bar girder plate Mutually the appearance in support reduction spillage or steel bar girder plate dislocation gap, the floor support plate upper surface are suitable with faying surface height So that steel structure girder and floor plates good integrity, anti-knock shock resistance are good, good waterproof performance, floor face is relatively more flat can directly to carry out powder Decorations handling.
Further, the supporting rib and the steel structure girder faying surface are welded to connect.The utility model is in steel bar girder The distance between the adjustable steel bar girder of supporting rib and steel structure girder is arranged in end, to further adjust on the floor support plate Surface and faying surface are high, and supporting rib plays a supporting role to steel bar girder end, greatly increases the knot of steel bar girder end Structure intensity.
Further, which is characterized in that each steel bar girder includes wind up reinforcing bar, lower edge reinforcing bar and web member steel Muscle, the supporting rib wind up with the one of branch triangular in shape reinforcing bar and the end reinforced connection of two lower edges respectively.The utility model branch Supportting muscle has stronger structural stability, reduces the waste of material to the greatest extent.
It further, further include additional muscle, the additional muscle both ends steel bar girder with steel structure girder two sides respectively End connection.The steel bar girder of additional muscle connection described in the utility model steel structure girder two sides, so that steel bar girder end connects More stable, the bonding strength of the end of steel structure girder is high after casting concrete and makes the floor plates after casting concrete solidification Ability and bearing capacity are cut in bending resistance with higher.
Further, the additional muscle includes upper additional muscle and lower attachment muscle, is bound on the reinforcing bar that winds up, lower edge reinforcing bar Be distributed muscle, the upper additional muscle and lower attachment muscle respectively with distributing reinforcement or the reinforcing bar that winds up, lower edge bar splicing.This is practical new Additional muscle is connect with upper lower edge reinforcing bar type respectively up and down or distributing reinforcement connects, so that being vertically connected with muscle with certain space layer It is secondary, make full use of the structural strength of additional muscle.
Further, including end additional muscle, the end additional muscle are located at described between two supporting ribs being oppositely arranged It is overlapped with upper additional muscle and lower attachment muscle.The utility model setting end distributing reinforcement forms two layers of reticular structure with muscle is vertically connected with, So that ability and bearing capacity are cut in the floor plates bending resistance with higher after casting concrete solidification.
Further, the distance that the upper additional muscle is located at one end to the steel structure girder axis of floor support plate side is greater than 300mm, the distance that the lower attachment muscle is located at one end to the steel structure girder axis of floor support plate side are greater than 200mm.The utility model The lap of splice of upper additional muscle is greater than the lap of splice of lower additional muscle, makes full use of the tensile strength of additional muscle, reduces material Waste.
Further, the gap of the floor support plate and the steel structure girder stitching portion is equipped with sealing plate, and the sealing plate prevents The concrete leakage poured.Described in the utility model sealing plate can be quickly laid with, effectively prevent floor plates and steel structure girder it Between gap generate spillage phenomenon.
Further, peg is welded on the upside of the steel structure girder.The utility model is arranged in steel bar girder end to be supported The bonding strength of muscle and weld stud increase and decrease floor plates and steel structure girder.
