The utility model aims at the above problem, a cast-in-place diaphragm plate operation platform of precast beam that can guarantee construction safety is provided.
The technical scheme of the utility model as follows:
the utility model provides a cast-in-place diaphragm operation platform of precast beam with adjustable which characterized in that: the device comprises two horizontal beams with a certain distance, a plurality of connecting rods are welded between the two beams, and a platform panel is laid on the connecting rods; a supporting beam is arranged right above each cross beam, a hanging rod is connected between the middle of each supporting beam and the middle of the cross beam below the supporting beam, and the length of the hanging rod is greater than the height of the bridge precast beam; the top of the two ends of each cross beam is provided with a height-adjustable supporting column, and the distance between the two supporting columns on each supporting beam is larger than the bottom distance between two adjacent precast beams of the bridge; the length of the supporting beam is larger than the top distance between two adjacent precast beams of the bridge.
The utility model discloses simple structure, low cost hangs in the precast beam below through a supporting beam and jib, through the tight precast beam bottom in support column top with adjustable, can guarantee after the installation that the platform is stable, avoids rocking, ensures personnel safety of being under construction on the platform. The guardrail adopts the assembled structure, and installation, dismantlement are convenient.

Detailed Description
As shown in fig. 1, 2 and 3, the utility model comprises two horizontal beams 1 with a certain distance, a plurality of connecting rods 2 are welded between the two beams 1, and a platform panel 3 is laid on the connecting rods; a supporting beam 4 is arranged right above each cross beam 1, a suspender 5 is connected between the middle of each supporting beam 4 and the middle of the cross beam 1 below the supporting beam 4, and the length of the suspender 5 is greater than the height of the bridge precast beam 11; the top of each two ends of each cross beam 1 is provided with a height-adjustable supporting column 6, and the distance between the two supporting columns 6 on each supporting beam is larger than the bottom distance between two adjacent precast beams 11 of the bridge; the length of the support beam 4 is larger than the top distance between two adjacent precast beams 11 of the bridge.
As shown in fig. 4, in the implementation of the present invention, the supporting column 6 can adopt the following structure to realize height adjustment: the support column 6 includes the screw rod 61 of a vertical setting, a bottom plate 62 of the lower extreme welding of screw rod 61, bottom plate 62 and crossbeam top surface welding, a nut 63 of the upper end spiro union of screw rod 61, nut 63 lower extreme and screw rod 61 upper end spiro union certain length, the backup pad 64 of a nut 63 upper end welding level setting.
The height of the support column is adjusted by rotating the nut 63 and changing the threaded length of the nut 63 and the screw 61. To facilitate turning the nut, two turning wrenches 65 may be provided on the side walls of the nut 63.
The utility model discloses during the concrete implementation, for guaranteeing constructor construction safety on the platform, install the guardrail on every crossbeam 1. The guardrail includes two guardrail pole settings 7, and the welding has guardrail horizontal pole 8 between two guardrail pole settings 7.
The guardrail adopts assembled mounting structure on the crossbeam. As shown in fig. 5, the lower end of each guardrail upright rod 7 is in threaded connection with the upper end of a threaded sleeve 9, the lower end of the threaded sleeve 9 is in threaded connection with the upper end of a guardrail positioning rod 10, and the lower end of the guardrail positioning rod 10 is welded on the top surface of the cross beam 1; two guardrail positioning rods 10 welded on each cross beam are positioned between the two support columns, and the distance between every two guardrail positioning rods is equal to or smaller than the bottom distance between two adjacent precast beams of the bridge.
As shown in fig. 1 and 2, the utility model is used for during cast-in-place construction of precast beam diaphragm, 11 back of targetting in place are installed at each precast beam, hang the platform to two adjacent precast beam below with the loop wheel machine on the bridge, two crossbeam crossbeams of platform are 1 to setting up, two spinal branch vaulting pole 4 crossbeams are to supporting at 11 tops of double-phase adjacent precast beam, through jib 5 with bracing piece and crossbeam firm in connection, rotate the nut of each support column 6, make 6 tops of support column top prefabricated beam 11 bottoms tightly, thereby guarantee that the platform is stable, avoid rocking. The constructor carries out the installation and construction of the steel bars and the templates of the transverse partition plate 12 on the platform panel.
