A construction method of a bearing device for the construction of a top bearing type inhaul cable comprises the following steps:

(1) a plurality of positioning seats 2 are arranged in the length direction of the building beams 1, truss composite slabs with the same number as the positioning seats 2 are laid between every two building beams 1, the truss composite slabs are in one-to-one correspondence with the positioning seats 2, and each truss composite slab comprises a bottom plate 3 and a plurality of trusses 4 arranged on the bottom plate 3. 3 overlap joints of bottom plate are between two building crossbeams 1, and the both ends of truss superimposed sheet all are equipped with corresponding positioning seat 2, and setting up of truss 4 can make the fastening more that concrete layer and bottom plate 3 combine when concreting in the later stage. If the building cross beam 1 is a metal beam, the positioning seat 2 is welded and fixed on the building cross beam 1, if the building cross beam 1 is a concrete precast beam, a convex embedded metal piece needs to be arranged in the building cross beam 1 during manufacturing, and the positioning seat 2 and the embedded metal piece are welded and fixed.

(2) And (3) placing a protective sleeve 5 on the periphery of each positioning seat 2 installed in the step (1), wherein the protective sleeve 5 is positioned on the building cross beam 1 and between the two truss composite slabs.

(3) And (3) a positioning column 6 is arranged on the positioning seat 2, so that the positioning column 6 is positioned in the protective sleeve 5 placed in the step (2).

(4) Every 4 last installation two inhaul cables 8 that have overspeed device tensioner 7 of truss, two inhaul cables 8 of every truss 4 are connected with the upper end of the reference column 6 at this truss 4 place truss superimposed sheet both ends respectively. Through adjusting tensioning device 7 can adjust the 8 lengths of cable between reference column 6 and truss 4 to and the position that whole truss superimposed sheet bottom plate 3 is located, take place the circumstances of bending downwards when avoiding appearing concrete placement.

(5) And adjusting a tensioning device 7 on each inhaul cable 8 to enable the heights of the middle parts of the bottom plates 3 of all the truss composite slabs and the two ends of the bottom plates 3 to be the same. The integral truss composite slab is kept at the same horizontal position before concrete pouring, and bending deformation of the middle part of the truss composite slab in the length direction is avoided when concrete is poured.

(6) And (3) laying reinforcing meshes 11 on the truss composite slab and the building cross beam 1 so as to further improve the building strength of the constructed floor slab.

(7) And (5) pouring concrete on each truss composite slab and the building crossbeam 1, so that the reinforcing mesh 11 and the truss 4 paved in the step (6) are embedded in the concrete, and the height of the poured concrete is not higher than that of the protective sleeve 5. As shown in fig. 4, the casting height of the concrete can be aligned with the height of the protective sleeve 5, and except for the space inside the protective sleeve 5, the building beams 1 and the truss composite slab are both cast with concrete, so as to facilitate the later dismantling operation of the positioning columns 6 in the protective sleeve 5.

(8) And (5) after the concrete poured in the step (7) is solidified, forming a cast-in-place layer, shearing off the stay cable 8 at the surface position of the cast-in-place layer, and dismantling the positioning column 6.

(9) And (5) pouring concrete into the protective sleeve 5 until the concrete is level with the cast-in-place layer formed in the step (8), and obtaining the laminated floor after the concrete is solidified. As shown in fig. 5, after the positioning columns 6 are removed, the building beam 1 and the truss composite slab form a level concrete pouring layer, i.e. a floor slab to be constructed. If the height of the protective sleeve 5 is higher than that of the cast-in-place layer after the pouring is finished, the position of the redundant height of the protective sleeve 5 can be manually cut off after the concrete is solidified.

Further, in order to ensure the connection strength between the positioning column 6 and the positioning seat 2, after the positioning column 6 is installed in the step (3), positioning pins are inserted into the positioning column 6 and the positioning seat 2, wherein through holes matched with the positioning pins are formed in the positioning column 6 and the positioning seat 2.

Furthermore, the positioning pin is a bolt 9, and after the positioning column 6 is mounted on the positioning seat 2, the bolt 9 penetrates through the positioning column 6 and the through hole of the positioning seat 2, and a fastening nut 10 is screwed on the bolt 9 in a matching manner, so that the positioning seat 2 is fixedly connected with the positioning column 6.
