The specific embodiment
The present invention is further described below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the mounting method of steel structure heavy embedded part of square billet bale turntable wall of the present invention comprises the steps: 1) make the steel plate 3 of built-in fitting, on steel plate 3, make through hole 5 with connector 4 correspondence positions; 2) 1 colligation becomes reinforcing cage with vertical reinforcement horizontal reinforcement 6; 3) steel plate 3 is separately fixed at the reinforcing cage both sides; 4) connector 4 is passed successively the through hole 5 of both sides steel plate 3; 5) regulate the position of steel plate 3, connector 4 to design attitude; 6) steel plate 3 is fixedlyed connected with connector 4.
This installation method is after treating that the reinforcing cage colligation finishes, built-in fitting to be assembled on the reinforcing cage good stability of reinforcing cage, handling safety, installation accuracy height again; Reinforcing bar has just been finished to tie up before built-in fitting is installed and has been rolled, and need not to pass built-in fitting again and carries out colligation, and easy for installation, time saving and energy saving, work efficiency is fast, easy construction, and installation cost is low.
For convenience in above-mentioned steps 5) in adjustment, described connector 4 is that the cross section is circular rod iron.By rolling, rotate the adjustment of more convenient position.
Described connector 4, steel plate 3 can be fixed by mode arbitrarily, as screw thread etc., in order to simplify the operation, reduce cost of manufacture, improve structural rigidity, and described connector 4 and steel plate 3 welding are fixing.
Welding for convenience increases weld strength, and described through hole 5 is a bellmouth orifice, and its adjacent end section shape with reinforcing cage is consistent with connector 4 cross sectional shapes, and other end cross section is greater than connector 4 cross sections.So just making on the thickness direction of whole steel plate 3 can through welding, the constant intensity height.Concrete, adapt with the connector 4 of circular cross-section, above-mentioned bellmouth orifice is a bellmouth.
Steel plate 3 is separately fixed at the reinforcing cage both sides,, therefore can be fixed in the reinforcing cage both sides or interim hook is fixed on the reinforcing cage or other modes by hanging device because steel plate 3 is provided with through hole 5.But because steel plate 3 weight are bigger, aforesaid way causes the distortion of steel plate 3 easily, thereby influences the structure precision of built-in fitting, and the positioning accuracy of aforesaid way is not high simultaneously, increases the adjustment workload in the step 5).
Therefore, best, before step 3), be provided with the support 2 that step a) is made built-in fitting steel plate 3; B) support 2 of both sides steel plate 3 is fixedly connected and be fixed on the reinforcing cage by support reinforcing bar 7 by support reinforcing bar 7; Described step 3) steel plate 3 is fixed on the reinforcing cage both sides by support 2.
Support 2 holds up steel plate 3, thus the quick location of realization steel plate 3, fixing.The position that two side stands are 2 guarantees by support reinforcing bar 7, the location also guarantees by the position of support reinforcing bar 7 between support 2 and the reinforcing cage, support 2, support reinforcing bar 7 weight are all light than steel plate 3, when support 2 is fixed on reinforcing cage, support 2, support reinforcing bar are 7 easy to operate, the location accurately, therefore, with steel plate 3 by support 2 fixing after, the positioning accuracy height of steel plate 3, it is little to adjust workload.
Above-mentioned support 2 can prefabricatedly also can directly be made on reinforcing cage, makes on reinforcing cage, and it is lighter that each parts is compared support 2, more convenient operation, and prefabricated precision is higher.Because mainly by the accuracy guarantee of steel plate 3 and through hole 5, therefore, operation is best for convenience for the built-in fitting precision, above-mentioned support 2 is tied up to roll at reinforcing cage and is directly made on reinforcing cage after finishing.
For the quick location of further realizing steel plate 3, fixing, described support 2 is shape and steel plate 3 corresponding to border structures, in the described steel plate 3 embedding supports 2.After steel plate 3 embedded support 2, circumferentially forming by support 2 of steel plate 3 was spacing fixing.
Further, described support 2 is made by angle steel.By the support 2 that angle steel is made, the spacing purpose of axial and circumferential is played to steel plate 3 respectively in two limits of angle steel, has further made things convenient for the quick location, fixing of steel plate 3.
Because support 2 location accurately, so the adjustment in the step 5) only need adjust connector 4 and get final product, and alleviated workload greatly.Steel plate 3, support reinforcing bar 7, the fixing of support 2 mainly are in order fast steel plate 3 to be fixed on the reinforcing cage by support 2.Therefore, operation for convenience, simultaneously the subsequent operation time longer, also in order to guarantee fixing at whole subsequent operation light plate 3, it is fixing to be welding between described support 2, support reinforcing bar 7, the reinforcing cage three, to guarantee precision and handling safety.Same, described steel plate 3, support 2 welding are fixed.Owing to be temporary fixed, best, the welding between support 2, support reinforcing bar 7, reinforcing cage, the steel plate 3 is spot welding, thereby realizes operation fast, fixing.
