Description
Technical field
The utility model relates to the operation platform that between a kind of precast stair, periphery shear wall obtains, and belongs to architectural engineering construction technique field.
Background technology
The develop rapidly of modern architecture industry; and Green Architecture Conception is universal; construction party has proposed very high requirement to green construction; implementing to concrete aspect, is exactly the requirement of saving land of proposing in < < green building assessment standard > >, energy-conservation, material-saving, water saving and environmental protection and comfortable space.In building construction process, the normal precast stair that adopts improves construction speed, but because precast stair lifting must lift after bridging piece beam concrete reaches bearing capacity intensity, about about 7 days of time, but after being arranged on 1 day, can install the shear force wall reinforcing steel bar of staircase periphery, reinforcement installation is checked and accepted well rear horse back and is carried out template installation, it is also to complete in 3 days that template is installed consolidation time, therefore, it between the situation that there is no hoisting prefabricated stair is gone downstairs, is exactly a cavity, there is no the operating platform that can allow workman stand, therefore cannot complete the shear force wall reinforcing steel bar of staircase periphery, template is installed, have a strong impact on the construction speed of engineering.In order to address this problem, the construction method of traditional staircase periphery shear wall is: adopt fastener type steel pipe scaffold to set up an operating platform at staircase, reinforcing bar and the template of utilizing this platform to carry out staircase periphery shear wall are installed, complete after shear wall concreting form removal, also need this operating platform to remove, when carrying out between last layer stair periphery shear wall construction, need organize workman again to set up new operating platform, set up the required steel tube fastener of platform and also have the materials such as plank to adopt tower crane to hang operation layer.Therefore, not only operation is more loaded down with trivial details for existing staircase periphery shear wall construction method, waste of manpower and financial resources, and also the process of setting up platform can waste the precious time, and affects construction speed.
Utility model content
The purpose of this utility model is, provide a kind of working procedure simple, convenient to operation, and be not subject to bridging piece beam concrete strength to affect the construction speed of shear wall, can effectively improve the operation platform of periphery shear wall between the precast stair of efficiency of construction, to overcome prior art deficiency.
The technical solution of the utility model: the operation platform of periphery shear wall between a kind of precast stair, comprise and adopt the rectangular frame of channel bar welding and be welded on the steel plate on rectangular frame, at the two ends of rectangular frame, adopt respectively group leader's supporting leg and one group of short supporting leg to be supported, and between rectangular frame and long leg and between rectangular frame and short supporting leg, be welded with respectively the first diagonal brace and the second diagonal brace;
Described rectangular frame both sides are connected with one group of turnover panel symmetrically by hinge;
Described rectangular frame both sides of the edge are welded with two groups of suspension ring symmetrically;
Described turnover panel is provided with shape of a hoof breach in the position of welding hanging ring;
Between described long leg, be welded with a cross bar.
Compared with prior art, the utility model has the advantage of: the utility model is not when the bridging piece beam concrete of newly building floor reaches the bearing capacity intensity that precast stair is installed, reinforcing bar and template that constructor cannot utilize precast stair to carry out staircase periphery shear wall are installed, in order to speed up the work, the utility model lifts an operation platform with newly building in the staircase of floor building floor in advance, this operation platform is monolithic operation platform, utilize this operation platform by the complete capping of the staircase in original cavity, therefore, constructor may stand in reinforcing bar and the template installation of carrying out staircase periphery shear wall on this platform, after this operation platform is finished using, by tower crane, hung away, continue on for the construction of the staircase periphery shear wall of upper strata floor.Therefore, adopt the utility model to carry out periphery shear wall construction between precast stair, working procedure is simple, and does not repeat to set up scaffolding platform, convenient to operation, effectively improves construction speed., after disposable the completing of operation platform in the utility model, can reuse meanwhile, save material.

The specific embodiment
In order to make the utility model object, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only for explaining the utility model, and be not used in restriction the utility model.
While adopting the utility model to carry out between precast stair periphery shear wall construction, first the size between the precast stair of job site is measured, comprising the vertical height of length, width and the precast stair of staircase, and then determine the size of needed operation platform.The step of making operation platform of the present utility model comprises a rectangular frame 5 of employing channel bar welding, then on rectangular frame 5, weld a steel plate 13 that 3mm is thick, by the complete capping of rectangular frame 5, at the two ends of rectangular frame 5, adopt respectively group leader's supporting leg 6 and one group short supporting leg 7 by its support simultaneously, and between rectangular frame 5 and long leg 6 and between rectangular frame 5 and short supporting leg 7, be welded with respectively the first diagonal brace 8 and the second diagonal brace 9, and between long leg 6, weld a cross bar 15, in order to strengthen the rigidity of whole operation platform; Then in rectangular frame 5 both sides, by hinge 14, connect symmetrically one group of turnover panel 11, and be welded with symmetrically two groups of suspension ring 10 in rectangular frame 5 both sides of the edge; For turnover panel 11 can freely be overturn on rectangular frame 5, described turnover panel 11 is provided with shape of a hoof breach in the position of welding hanging ring 10, thereby avoids suspension ring 10.
After operation platform of the present utility model completes, for accelerating construction progress, can be when the bridging piece beam concrete of newly building floor 3 reach the bearing capacity intensity that precast stair 1 is installed, building floor 2 and newly building this operation platform of the interior lifting of staircase 12 of floor 3 in advance, after operation platform lifts, the height of operation platform is now higher than newly building floor 3 upper surface 10cm, the lifting of constructability platform later stage, then open the turnover panel 11 on operation platform, make operation platform by the complete capping of the staircase in original cavity 12, therefore, constructor can stand on this operation platform staircase 12 periphery shear walls 4 are carried out to reinforced-bar binding and template installation, easy construction safety.After the reinforced-bar binding and template installation of shear wall 4 on newly building floor 3, just can build the concrete of this story shear wall 4, after treating the concrete curing of shear wall 4, constructor may stand on this operation platform equally by staircase 12 periphery shear wall 4 form removables, then adopt tower crane that operation platform is hung away, continue on for the construction of the staircase periphery shear wall of upper strata floor; Finally, precast stair is lifted on and builds floor 2 and newly build in the staircase 12 of floor 3, complete whole staircase periphery shear wall construction process.
