Detailed description of the invention
A kind of firm web suspension type construction hanging basket of waveform, as illustrated in fig. 1 and 2, is mainly made up of load bearing system, hanging lifting system, running gear, template system, and wherein load bearing system includes the firm web 3 of entablature 1, lower longeron 8 and waveform;Hanging lifting system includes rear fulcrum suspension rod 5, central bearing point suspension rod 6, front fulcrum suspension rod 2.Running gear includes hydraulic stem 12, the groove 13 on firm web 3 top that is arranged on waveform, tetrafluoro slide plate 14, sliding beam 4 and walking dolly 15;Template system includes top template, end template, end-blocking mould and work platforms.
Supporting beam and embed in the firm web groove 13 of waveform, spiral crosses through hole and supports beam hole, bolt anchoring.Make to support beam 16 to be fixed in groove 13.Thus, the strong point of Hanging Basket is anchored in the firm web chute of waveform, is connected with the firm web supramarginal plate perforate of waveform and Hanging Basket fulcrum.Tetrafluoro slide plate 14, coating butter in groove 13 is set supporting pad between beam 16 and groove 13.In the firm web chute 13 of waveform, tetrafluoro slide plate is more than fulcrum width 10cm, and slide plate edge upper uplifting angle degree is 45 °.
Support the upper longeron 17,25 of beam 16 top welding.Supporting, beam 16 sets up entablature 1, with bolt anchoring central bearing point suspension rod 6 upper limb on entablature 1.Central bearing point suspension rod 6 lower edge bolt anchoring sill 18.
Rear entablature adopts 2I45b I-steel composition steel case, and front entablature adopts 2I40b I-steel composition steel case, connects with 2 road 2I25b I-shaped steel longitudinal beams and form Hanging Basket bearing platform between two entablatures.Each suspension rod adopts 40Cr suspension rod and two kinds of φ 32 fining twisted steel suspension rod, and in order to increase the general character of Hanging Basket, 40Cr suspension rod is two kinds of specifications of 3.5m, 1.75m, all adopts adapter to connect.Vary in size according to stress at each suspension centre place and prepare different size jack respectively as promoting power, in order to can quickly adjust formwork elevation measuring in time, improve production efficiency, shorten construction period.
Sliding beam 4 parallel shelf is located at the both sides of the firm web 3 of waveform, rear fulcrum suspension rod 5 and central bearing point suspension rod 6 fix described sliding beam 4.Sliding beam is fixed by rear fulcrum and central bearing point, and the sliding beam gradient should keep consistent with box beam top longitudinal gradient.Sliding beam equidistantly sets up horizontal I-steel, I-steel is set up firm model.
It is yi word pattern steel that adjacent continuous three construction block section arranges horizontal temporary support, upper limb and lower edge temporary support, and centre is I shape shaped steel.
Base plate side template 22 is used for controlling underplate concrete and builds thickness, and operation platform 24 is for the construction in each stage.
The method that box beam is constructed by waveform firm web construction hanging basket is utilized to comprise the following steps: 1) the assembled order of Hanging Basket is: the falsework → laying tetrafluoro skateboard track → forward and backward fulcrum of installation Hanging Basket (temporarily consolidating) → longitudinal beam connected → forward and backward entablature → suspension rod → forward and backward sill → bottom girder → template between Wavelike steel webplate is installed.
2) pine hanging basket formwork: after box beam concrete roof reaches intensity in the last period, first unclamp top board mould, mounting slip dolly, suspension bracket stress is reached on sliding trolley by the rear suspension bar synchronizing the sliding beam of slow removal with jack, reduce anchor point before sliding beam simultaneously, template is slowly peeled off concrete roof, namely complete external mold dismounting in top board.Jack synchronizes slowly to reduce successively forward and backward sill, and template is peeled off bottom board concrete, and the dismounting and the Hanging Basket walking that namely complete end platform prepare.
3) hanging basket advancing: be anchored on Wavelike steel webplate open pore steel plate by the hydraulic stem being arranged on rear fulcrum place by steel pin, utilizes 2 hydraulic stems to synchronize slowly to draw hanging basket advancing.
During construction, m+1 block section falsework is installed the firm web 3 of waveform, A class support the installation accuracies of 9 and B class support 10 control Wavelike steel webplates.One end of described hydraulic stem 12 is tightened with bolt with the through hole 19 on groove 13 sidewall of the firm web 3 of waveform, and the other end of hydraulic stem 12 inserts in the notch supporting beam 16.During construction, electric oil pump oil return, hydraulic stem 12 draws rear fulcrum suspension rod 5 slip and drives whole Hanging Basket to advance, after reaching a stroke, the steel pin that will pass through in hole 19 takes off, Hydraulic Station fuel feeding, steel pin is utilized again to be anchored on through hole 19 by support beam 16 after reaching stroke, restart hydraulic stem 12, start next stroke action, and so forth several times until promoting hanging basket advancing to m+1 block section place.
In work progress, top board end template 20 is transported to and treats casting position by travelling bogie 15.The sliding beam 4 of length to be built arranges the horizontal I-beam of welding, and on I-beam, sets up top board end template 20.The inclination angle of sliding beam 4 is regulated so that top board end template 20 front-end control point reaches formwork erection elevation by rear fulcrum suspension rod 5 and central bearing point suspension rod 6.When building the concrete roof of m block section, regulate rear fulcrum suspension rod 5 and front fulcrum suspension rod 2 simultaneously, make bottom die plate 21 adjust to controlling elevation.Build m+1 block section underplate concrete, then set up falsework in m+2 block section, support is installed the firm web 3 of waveform.
M block section concrete roof is built, m+1 block section is built underplate concrete and built and set up the firm web installation section of waveform with m+2 block section and stagger and be synchronously performed.After completing, enter back into next circulation construction procedure.
In a word, cradle structure of the present utility model is directly set up on the firm web chute of waveform, the firm web of waveform undertake Hanging Basket, template system and construction temporary load(ing), it is not necessary to arrange cantilever I-steel and walking channel-section steel, alleviate the deadweight of cradle structure, increase the safety coefficient of antidumping.Tetrafluoro slide plate is set in the firm web chute of waveform, reduces Hanging Basket and slide friction, accelerate wheel efficiency.This cradle structure achieves the function of extension work surface, and cantilever construction work surface has been divided into m block section work surface (building top board), m+1 block section work surface (building base plate), m+2 block section work surface (cantilever Hanging Basket).Construction speed is made to improve more than 35%.
The content that above-described embodiment illustrates should be understood to these embodiments only for being illustrated more clearly that this utility model, rather than limit scope of the present utility model, after having read this utility model, the amendment of the various equivalent form of values of the present utility model is each fallen within the application claims limited range by those skilled in the art.
