Abstract
The utility model relates to a building die support, in particular to an ultrahigh and overlong cantilever structure type steel suspension frame which solves the technical problem of installation of a template support in building high-altitude inverted-cone eave construction. The ultrahigh and overlong cantilever structure type steel suspension frame comprises a plurality of single-rack suspension-type steel frames, wherein each suspension-type steel frame structurally comprises an upper right-angle side and a bevel edge, the length of each upper right-angle side is 6m, the vertical height of the bevel edge is 7.29m, reinforcing ribs are arranged between the upper right-angle side and the bevel edge, and installation embedded parts are reserved in structural construction of a building with elevation of 36.06m and 43.35m. One cantilever beam can be used by two floors. The supporting structure of a frame body is good in intensity, stiffness, integral stability and antidumping performance.
Description
Technical field
The utility model relates to a kind of building mould support, is specially a kind of superelevation overlength cantilevered structure shaped steel hanger.
Background technology
The building design model is more and more diversified, complicated at present, and traditional job practices is this special structure construction of more and more difficult adaptation.For example the design of certain building drawing absolute altitude 48.4,51.1m place peripheral encorbelment have 3.45, back taper eaves that the beam and slab type of 5.0m is encorbelmented the concrete structure.Because this project is to carry out setting up of falsework on the high-altitude of 45m, construction is dangerous big; The length requirement of encorbelmenting is longer; And the two-layer use of beam of once encorbelmenting.So the intensity of support body braced structures, rigidity, resistance to overturning, anti-overturning are the key points that guarantees support body safety.Also there is not at present relevant technology report to use for reference.
Summary of the invention
The utility model provides a kind of superelevation overlength cantilevered structure shaped steel hanger in order to solve the technical problem that falsework is installed in the back taper eaves construction of building high-altitude.
The utility model is realized by following technical scheme, a kind of superelevation overlength cantilevered structure shaped steel hanger, comprise some single Pin suspension type steelframes, each suspension type steel frame construction comprises right-angle side, hypotenuse, last right-angle side length is 6m, the vertical height of hypotenuse is 7.29m, between right-angle side and hypotenuse, be provided with reinforcing rib, when building absolute altitude 36.06,43.35m structure construction, reserve embedded part is installed.
Steelframe height described in the utility model is 6m, and span reaches two floor distances.Solved the problem that falsework is installed in the back taper eaves construction of building high-altitude, the construction formwork support adopts fastener type steel pipe scaffold, and steel pipe framed bent at the bottom of the beam is full hall scaffold at the bottom of the plate.The two-layer use of beam of once encorbelmenting.The intensity of support body braced structures, rigidity, resistance to overturning, anti-overturning are good.
The specific embodiment
Fig. 1 is an installation site of the present utility model schematic diagram
Fig. 2 is a structural representation of the present utility model
Among the figure: 1-building, 2-encorbelment, 3-encorbelments, embedded part, 6-hypotenuse, the straight reinforcing rib of 7-, the oblique reinforcing rib of 8-, the last embedded part of 9-, the last right-angle side of 10-under the 4-steelframe installation site, 5-.
The specific embodiment
As schematically shown in Figure 1, formwork-support begins to set up from the 43.35m absolute altitude, consider the requirement of outer protective frame and tension of prestressed tendon, the frame of the encorbelmenting length of encorbelmenting reaches 6m, 39.66m locate floor height 3.69m, therefore the diagonal brace angle is undesirable, need do the encorbelment diagonal brace fulcrum of beam of shaped steel from 36.06 m frame beams.The braced structures of falsework is single Pin suspension type steelframe, and steelframe is the chamfer triangle, and length is 6m, highly is 7.29m.After 36.06m beam and slab structure concrete C30 reaches 100%, steelframe can be installed.
As schematically shown in Figure 2, a kind of superelevation overlength cantilevered structure shaped steel hanger, comprise some single Pin suspension type steelframes, each suspension type steel frame construction comprises right-angle side 10, hypotenuse 6, last right-angle side 10 length are 6m, the vertical height of hypotenuse 6 is 7.29m, between last right-angle side 10 and hypotenuse 6, be provided with reinforcing rib, when building absolute altitude 36.06,43.35m structure construction, reserve embedded part is installed.Described reinforcing rib comprises straight reinforcing rib 7, oblique reinforcing rib 8, and described embedded part is last embedded part 9, following embedded part 5.
Job practices is: 36.06, reserve during the 43.35m structure construction embedded part is installed; Field fabrication steel framework; Adopt tower crane to lift cooperation when the steel framework is installed, accomplish solid and reliable during installation; Install by Pin, big face is installed earlier, the bight is installed again; Steelframe carries out an acceptance inspection after installing; Welding short steel pipes head is used for fixing vertical rod on the steelframe; Completely spread 50 planks on the steelframe; Set up totally-enclosed outer protective frame; The requirement that carries into execution a plan of setting up of formwork-support, the spacing of column, array pitch, step pitch, the bar of sweeping the floor, bridging, wall-connecting piece strictness.
Material that steelframe is selected for use and specification, quality and performance requirement: material requirements: steel material, steel plate, steel pipe, shaped steel etc. must adhere to specification, as there is not product certificate or when with suspicion, must be undertaken by the regulation of existing national standard " code for acceptance of construction quality of steel structures " GB50205-2001, verifiedly can use after meeting standard and designing requirement.Raw material, its kind, specification, performance etc. should meet existing national product standard and designing requirement.And the certification of fitness prescribed paper of product arranged.By inspection of quality, must meet the requirement of other master control project and general data.
Connect material: welding rod, etc. connect material, answer master control project and the general data and the designing requirement of compliant regulation, and Certificate Of Conformance arranged.
