Description
Technical field
The present invention relates to steel concrete horizontal member operation platform and the construction method thereof of a kind of building operations auxiliary part and construction method thereof, particularly a kind of superelevation.
Background technology
In public building design, usual employing courtyard forms the space of autonomous closure in building or architectural complex inside, both the function of daylighting can have been realized, building content can also be enriched, realize the function of public building exhibition, sightseeing and amusement and recreation, but in structure construction, herein beam-slab template conveniently way be set up Super High Form Formwork, need long-term to drop into a large amount of scaffolds, and in construction, there is the difficult points such as the narrow and difficulty of construction of haul inconvenience, the steel pipe spacing little workman scope of operation is large.
Summary of the invention
The object of this invention is to provide a kind of construction method of hollow ultrahigh template section steel platform, in the horizontal member constructions such as the courtyard place beam slab of the hollow that solve, template sets up the technical problem of difficulty.
For achieving the above object, the present invention adopts following technical scheme:
A kind of hollow ultrahigh template section steel platform, template scaffold building thereon, comprise lateral type girder steel, longitudinal type girder steel, scaffold floor, support scaffolding and at least two contour lower template platforms, the two ends of described lateral type girder steel are set up respectively on two lower template platforms, and fixed by end winding support part, described longitudinal type girder steel vertical rack is located on lateral type girder steel, and be fixedly connected with lateral type girder steel, the plane that described longitudinal type girder steel and lateral type girder steel intertexture are formed lays scaffold floor, plane lower support has support scaffolding, described support scaffolding and lower template platform are by pull bar drawknot.
Described lateral type girder steel and longitudinal type girder steel are steel I-beam, H profile steel beam, steel beam with box shape or above-mentioned any combination.
Described lateral type girder steel end face is arranged at intervals with bar dowel, and the bottom of upright rod of described template scaffold inserts bar dowel.
The length of described bar dowel is not less than 15cm, and the vertical rod internal diameter of its diameter and template scaffold matches.
Described end winding support part is anchor ring or U-shaped reinforcing bar.
The construction sequence of above-mentioned hollow ultrahigh template section steel platform is as follows:
Step one, is placed lateral type girder steel at lower one deck hollow place of the steel concrete horizontal member intending construction, and is fixed at lateral type girder steel two ends by end winding support part; Often end fixes 2 points, respectively apart from end face 200mm and 1000mm intending the steel concrete horizontal member of constructing;
Step 2, divides into support scaffolding at lateral type girder steel; Support scaffolding is positioned at lateral type girder steel middle part, and support scaffolding sets up width depending on lateral type girder steel span, should be calculated determine by girder steel amount of deflection; The vertical pole ' s span 600mm-1200mm of support scaffolding, horizon bar spacing 900mm-1800mm, if 60 degree of bridgings, determined by support body stable calculation; Meanwhile, if support body height is more than 8 meters, transverse direction and pillar or beam slab drawknot should be considered, prevent support body from tilting;
Step 3, with longitudinal type girder steel along being linked to be entirety perpendicular to lateral type girder steel length to welding, ensures section steel beam platform and integrally; Then completely scaffold floor is spread;
Step 4, under section steel platform, control point is set, carry out deflection observation to lateral type girder steel end and middle part, four-stage carries out after observation point shaped steel putting up platform, after the reinforcement installation of steel concrete horizontal member, in concreting and after concrete initial set;
Step 5, the vertical rod intending the template scaffold of the steel concrete horizontal member of construction accurately drops on the bar dowel on lateral type girder steel; The stencil design of the steel concrete horizontal member of constructing according to the plan at top sets up template scaffold, lays steel concrete horizontal member template, lays reinforcing bar, concreting;
Step 6, waits that the concrete strength of the steel concrete horizontal member intending construction reaches 100% of design strength, carries out the dismounting of steel concrete horizontal member template; After dismounting, courtyard constructional appearance is carried out an acceptance inspection, insert steel concrete horizontal member decoration construction in advance, reduce section steel platform life cycle;
Step 7, section steel platform is removed, and is first disconnected by longitudinal type girder steel, is removed by lateral type girder steel, finally remove support scaffolding from top to bottom by root.
Compared with prior art the present invention has following characteristics and beneficial effect:
The present invention can be placed in the template of one deck under construction layer and set up platform, falsework set up by this platform, to reduce the scaffolding height of formwork-support, for workman provide broad, working space easily, also can reduce the input of steel pipe scaffold simultaneously, difficulty of construction is reduced greatly.
The present invention makes formwork-support set up and is kept to individual layer height by superelevation height, and provides enough job platforms easily for workman, and platform can conveniently way be set up, simple operation, construction is simple.Support system below i-shape steel beam is compared with the support body of traditional construction mode, and scaffolding height is little, and it is little that support body sets up width, and the arrangement pitch of cross bar, vertical rod, bridging is slightly aobvious loose, and workman's easy construction, the steel pipe quantity of input is few.Scaffold floor above section steel platform be completely taped against position and fixing can rearward, the upper and lower support work of setting up of platform can be constructed simultaneously.The support system of this platform upper and lower dismountable after structure construction, retains this platform and continues to use in the decoration construction stage.Improve efficiency, accelerate speed of application, save the duration, save construction cost.Can similar across the construction of hollow structure in take the method.
The construction scaffolding that the present invention can be widely used in the horizontal members such as hollow position place beam slab is set up.
