Description
Technical field
The utility model belongs to box girder inner formwork servicing unit technical field in prefabricated box-beam construction, is specifically related to a kind of device preventing the swollen mould of box girder inner formwork.
Background technology
Along with developing rapidly of highway, prefabricated case beam is widely used in bridge construction, first builds end web concrete, the phenomenon that box girder inner formwork can be caused to float, have a strong impact on prefabricated box-beam quality in existing prefabricated box-beam process.With regard to current prefabricated box-beam, in prefabricated case beam casting process, internal mold floating extensively exists, and existing do not have method head it off well, and how solving internal mold floating in prefabricated case beam casting process is urgent need to solve the problem in prefabricated box-beam construction.
Summary of the invention
The utility model is solve the technical problem that in prefabricated case beam casting process, internal mold floats, and provides a kind of device preventing the swollen mould of box girder inner formwork.
The technical solution adopted in the utility model is as follows:
A kind of device preventing the swollen mould of box girder inner formwork, comprise four leg bases, pressure thick stick, steel wire rope I, turnbuckle, steel wire rope II and annular bolt, described four leg bases are placed on box girder inner formwork upper surface middle part, described pressure thick stick is symmetrical to be placed on four leg bases, the two ends of pressure thick stick are provided with the circular hole be convenient to steel wire rope I and passed, one end of steel wire rope I is each passed through presses the circular hole at thick stick two ends to adopt steel wire clamp to be fixed on pressure thick stick, the other end of steel wire rope I is connected with the upper end of turnbuckle respectively, annular bolt is embedded in the both sides of precast beam pedestal respectively, one end of steel wire rope II is connected with the annular bolt of the left and right sides respectively, the other end is connected with the lower end of the turnbuckle of the left and right sides respectively.
Described annular bolt embedment is at 1.5m place, precast beam pedestal both sides.
Described pressure thick stick adopts 12cm channel-section steel make-up to be welded.
Described four leg bases employing diameters are that the spiral of 28mm is welded.
Using method of the present utility model: after case beam steel and model sheetinstallat complete, four leg bases of the present utility model are placed on correspondence position, four leg bases are placed the pressure thick stick that 12cm channel-section steel make-up is welded, connect steel wire rope and turnbuckle, both sides correspondence tightens turnbuckle, fix box girder inner formwork position, build web concrete at the bottom of case beam, by this device to internal mold precompressed, reach the object preventing box girder inner formwork from floating, until concrete roof built carry out secondary receive face time, anti-swollen die device is removed.
The beneficial effects of the utility model:
1. the utility model structure is simple, easy to operate, efficiently solves the problem that in prefabricated case beam casting process, internal mold floats.
2. steel wire rope I of the present utility model is fixed on pressure thick stick by steel wire clamp, and one is safety when ensureing applying power, and two is avoid each use to install it, saves the time, improves work efficiency.
