Description
Technical field
The utility model relates to a kind of bridge construction system, is a kind of bridge construction sliding mode system specifically.
Background technology
Sliding shuttering in the bridge construction construction works is a kind of remarkable shortening formwork time, reduces the sliding consumption of template, the advanced technology that the bridge pier that the cast on-site shape and structure is single, dam body or the like reinforced concrete member generally is fit to.Sliding formwork not only comprises tool-typed formworks such as common template or dedicated templates, also comprise the sliding comprehensive technologys such as equipment and matching operation technology that rise of power, mainly be the sliding power that rises at present with the hydraulic jack, under the synchronous effect of jack in groups, drive concrete surface or the template surface slip of tool-typed formwork high more than 1 meter or sliding sash along firm moulding, water in the suitable for reading minute course grooving of concrete by template, every layer generally to be no more than 30cm thick, after undermost concrete reaches certain intensity in the template, the template grooving relies on the effect that promotes facility, slide or sliding sash slides along the template external surface along the concrete surface that watered, upwards slide about about 30cm again, continuous cycle operation like this like this up to reaching design height, is finished whole construction.The shortcoming of two existence of systems face is:
1. the pier tilt problem of system.The reason that causes pier to tilt is a lot, and main cause is that inclination has taken place operating platform, the easiest cause that operating platform tilts be exactly the inclination of hoisting frame or collapse.
2. the synchronous lifting problem of the hoisting frame of system.Guarantee the accuracy of module position, necessarily require each module to want relative horizontal equilibrium in the process sliding the liter, this has just had higher requirement to the balance of Hoisting System, and prior art is to this not more processing and protection.
The utility model content
The utility model provides a kind of can carry out anti-fall anti-dumping processing to scaffold, and can make each module better synchronous bridge construction sliding mode system in lifting process.
A kind of bridge construction sliding mode system comprises a gin pole, hoisting scaffold, Hoisting System, template, control module, it is characterized in that: described scaffold and gin pole have the anti-dumping anti-drop device, and described Hoisting System has synchro system.
Because the anti-dumping anti-drop device that the utility model adopts is protected scaffold, makes operating platform more firm, thereby the situation of having avoided pier to tilt takes place; Since to having added synchro system in the Hoisting System, feasible more stable to the lifting of module, avoided potential safety hazard, further the balance of pier is stablized.
Further, consider the stable and economic dispatch aspect of anti-dumping anti-drop device, described anti-dumping anti-drop device comprises two guide rails of hoisting scaffold, the long limit of guide rail is welded back-to-back by two channel-section steels, is welded with equal reinforcing rib of spacing and steel plate outside one of them guide rail along its length as anti-fall; The anti-dumping anti-drop device also comprises screw rod, swivel nut seat, L shaped guiding crotch, and the length of the push rod of being made up of screw rod, swivel nut seat can need be regulated by this screw pair by using.Wherein push rod and L shaped guiding crotch load, the length of push rod can be by using the screw pair adjusting that need be made up of screw rod and swivel nut seat.Because it is cheap easily that related original paper is drawn materials, and simple in structure, stressed clear, reached the purpose of forming a stable and economic anti-dumping anti-drop device.
Further, consider the synchronism problem that module promotes, synchro system comprises on the seat in the plane of module correspondence of each face and is respectively equipped with measurable montant, also be respectively equipped with the photoelectric sensor of each montant of monitoring on the gin pole, be parallel to each other between each montant, the level height of each photoelectric sensor survey mark is identical, and photoelectric sensor is transferred to control module to the situation of the montant that obtains, control module to information handle the back to lifting appliance control reach to module promote synchronously; This synchronous system architecture is simple, convenient and practical, by true monitoring to module lifting appliance operation conditions, avoided understanding and having an accident because only lack to the monitoring of power-equipment and to the actual conditions of module lifting appliance, realize synchronous operation, and the concrete structure with power-equipment is irrelevant, no matter be that electric block or hydraulic test can be realized.
Further, consider the driving arrangement problem of Hoisting System, described Hoisting System comprises electric block, and the electric block simple structure is economical and practical, and is strong to adaptive capacity to environment.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the schematic diagram of embodiment of the present utility model
Fig. 2 is the schematic diagram of the anti-drop system of embodiment of the present utility model
Fig. 3 is the schematic diagram of the anti-dumping system of embodiment of the present utility model
The specific embodiment
As shown in Figure 1, a kind of bridge construction sliding mode system, comprise a gin pole 1, hoisting scaffold 4, electric block 7, template 3, control module, hoisting scaffold 4 has anti-tilt device 11 and anti-drop device 2, be connected with crossbeam 6 on the gin pole 1, crossbeam 6 is used for connecting electric block 7 and transports concrete, electric block 7 is connected with template 3 with crossbeam 6, electric block 7 is used for climbing shuttering 3, steel pipe 8 is fixed on the template 3, have every 5mm on the steel pipe 8 and be provided with a mark, photoelectricity correlation switch 9 is fixed on the crossbeam 6, the motion conditions that is used for measuring steel pipe 8 obtains the real motion situation of template 3 with this, is erected with working platform 10 and is used for carrying out construction sequences such as concrete cast stirring between each hoisting scaffold 4.During work, the photoelectricity correlation switch 9 of each face monitors the lifting situation of template 3 and is transferred to control module, by the lifting situation of the template 3 of each face relatively, the power drive of adjusting electric block 7 makes the motion conditions of template 3 of each face unified as far as possible, and the relative position relation by template 3 and hoisting scaffold 4 reaches and allows the purpose of pier balance.In addition, also hoisting scaffold 4 be provided with reinforcing rib that spacing equates and steel plate as anti-fall 5 by the two-sided channel-section steel 41 that is welded back-to-back of gin pole one side, be used for and anti-drop device 2 cooperates to reach anti-fall effect.
