Description
Technical field
When the utility model relates to the construction of a kind of overlength cantilevered structure, type steel support structure, below especially a kind of thing, floor height is higher or choose the self-balancing steel builder's jack that overlength causes diagonal brace longer outward.
Background technology
When running into the construction of overlength cantilevered structure, the general steel builder's jack that adopts is set up, and namely adopts type steel support form below girder steel in the past.The stressed power transmission of original technical system is obvious, and form is simple.But when diagonal brace is below long, the easy unstability of diagonal brace, needs to form steel truss form and just can guarantee resistance to overturning.Meanwhile, below one deck floor height must not be too high, otherwise also can cause type steel support unstability, or need the shaped steel diagonal brace taking relatively large number, therefore cause diagonal brace longer when cutting optimal height is higher or choose overlength outward, steel bracket adopt below diagonal brace time, diagonal brace length is very long.Therefore adopt pull-up diagonal brace to solve the stressed and amount of deflection problem of steel bracket.But smash because superstructure concrete now not yet waters, pull-up diagonal brace cannot be fixed, and original Technical Economy and safety all not ideal enough.
Summary of the invention
The utility model to provide a kind of self-balancing steel builder's jack for the construction of overlength cantilevered structure framed bent, steel builder's jack is externally chosen framed bent by self-balancing and is carried, without the need to relying on next Rotating fields, monolithic stability is reached by rear anchor and longitudinal restraint, guarantee that bent frame system is stablized, the danger of framed bent of encorbelmenting is reduced to minimum, installs and set up quality and also easily ensure.
For achieving the above object, the technical solution used in the present invention is: a kind of self-balancing steel builder's jack for the construction of overlength cantilevered structure framed bent, comprise the steel outrigger that overlength is encorbelmented, a shaped steel column for fixing pull-up diagonal brace is installed at steel outrigger fulcrum place, at least one pull-up diagonal brace upper end is fixedly connected on the shaped steel column of the end side of encorbelmenting being in steel outrigger, lower end is fixedly connected with the end of encorbelmenting of steel outrigger, simultaneously at shaped steel column opposite side rear anchor steel diagonal brace for steel outrigger self-balancing together with arranging at least between anchor end after steel outrigger.
When the cantilever span of steel outrigger is not more than 2m, arrange one pull-up diagonal brace, corresponding shaped steel column is rear anchor steel diagonal brace together with arranging between anchor end after steel outrigger.
During the cantilever span 2m-4m of steel outrigger, two road pull-up diagonal braces are set, after corresponding shaped steel column and steel outrigger, between anchor end, anchor steel diagonal brace behind two roads are set.
Shaped steel column is provided with the cannelure steel cross strut for self-balancing steel builder's jack population equilibrium.
After steel outrigger, anchor end is fixedly connected with structure floor, wherein, i iron two side in steel outrigger in anchor end and upper end installing timber wedge, timber wedge is around with pressure ring reinforcing bar, pressure ring reinforcing bar two end anchored end respectively with soffit bar connecting after, in floor, extend one section of anchored end reinforcing bar meeting anchorage length.
The beneficial effects of the utility model are:
Floor height is higher below, steel bracket adopt below diagonal brace time, diagonal brace length is very long.Therefore adopt pull-up diagonal brace to solve the stressed and amount of deflection problem of steel bracket.But smash because superstructure concrete now not yet waters, pull-up diagonal brace cannot be fixed, so corresponding framework is set self by steel builder's jack carry out system stress balance.At steel outrigger fulcrum place, a shaped steel column is installed, fixes pull-up diagonal brace by shaped steel column, carry out shaped steel diagonal brace balance at shaped steel column opposite side simultaneously, longitudinally by channel-section steel bridging, population equilibrium is carried out to shaped steel column.Steel outrigger is externally chosen framed bent by self-balancing and is carried, and without the need to relying on next Rotating fields, reaching monolithic stability by rear anchor and longitudinal restraint, guaranteeing that bent frame system is stablized, be reduced to minimum by the danger of framed bent of encorbelmenting, and installs and sets up quality and also easily ensure.

Detailed description of the invention
As shown in Figures 1 to 4, a kind of self-balancing steel builder's jack for the construction of overlength cantilevered structure framed bent, comprises steel outrigger 1 that overlength encorbelments, shaped steel column 2, pull-up diagonal brace 3, rear anchor steel diagonal brace 4 etc. for fixing pull-up diagonal brace.
A shaped steel column 2 is installed at steel outrigger 1 fulcrum place, at least one pull-up diagonal brace 3 upper end is fixedly connected on the shaped steel column 2 of the end side of encorbelmenting being in steel outrigger 1, lower end is fixedly connected with the end of encorbelmenting of steel outrigger 1, for the rear anchor steel diagonal brace 4 of steel outrigger self-balancing simultaneously together with arranging at least between shaped steel column 2 opposite side with anchor end after steel outrigger 1.Shaped steel column 2 is provided with the cannelure steel cross strut for self-balancing steel builder's jack population equilibrium.
As shown in Figure 4, after steel outrigger 1, anchor end is fixedly connected with structure floor 5, wherein, i iron two side in steel outrigger 1 in anchor end and upper end installing timber wedge 6, timber wedge 6 is around with pressure ring reinforcing bar 7, after pressure ring reinforcing bar 7 two end anchored end is connected with soffit reinforcing bar 8 respectively, in structure floor 5, extend the anchored end reinforcing bar that a section meets anchorage length.In steel outrigger 1, anchor end and structure floor 5 are effectively fixed, and need if desired to carry out partial structurtes reinforcing.
As shown in Figure 3, when the cantilever span of steel outrigger 1 is not more than 2m, one pull-up diagonal brace 3 is set, anchor steel diagonal brace 4 after together with arranging between corresponding shaped steel column 2 with anchor end after steel outrigger 1.
As shown in Figure 1, during the cantilever span 2m-4m of steel outrigger 1, two road pull-up diagonal braces 3 are set, after corresponding shaped steel column 2 and steel outrigger 1, between anchor end, anchor steel diagonal brace 4 behind two roads are set.
The utility model scope of application: consider general floor height situation, according to the design principle of self-balancing steel builder's jack, choosing length outside cantilevered structure, to be not more than 4m more applicable.When wherein cantilever span is not more than 2m, arrange one pull-up diagonal brace 3, after corresponding column, anchor also arranges anchor steel diagonal brace 4 together; During cantilever span 2m-4m, arrange two road pull-up diagonal braces 3, after corresponding column, anchor also arranges anchor steel diagonal brace 4 behind two roads.
