Abstract
A kind of cast-in-place concrete stair is marked time set shaped steel formwork, comprises elevating screw, step plate, mark time beam and reinforced bar support, and described elevating screw is placed in set shaped steel formwork two ends platform, and it is vertically arranged; Described step plate is equidistant setting vertically, and it is fixedly connected with the beam of marking time be obliquely installed; Described reinforced bar support is fixedly connected on marks time beam between angle bar.The beneficial effects of the utility model are, cast-in-place concrete stair of the present utility model is marked time set shaped steel formwork, and speed of application is fast, good control gangboard thickness, solve the problem of formwork difficulty of parameter tuning, ensure that construction quality, alleviate the labour intensity of workman.Can be used for single flight and two race stair.
Description
Technical field
The utility model relates to a kind of cast-in-place concrete stair and to mark time set shaped steel formwork, belongs to the realm of building construction.
Background technology
In high building project work progress, the traditional method of stair template adopts wooden template, and each is marked time and installs one piece of template, and supports, and forms stepped empty mould, then in empty mould concreting step by step, stripping after concrete setting.And in demolishing process, be difficult to ensure the integrality of template, can only single use, wooden form need be repaired step surface toward contact after removing, and has certain influence, and add the labour intensity of construction worker to construction speed and quality.
Utility model content
For the deficiency that prior art exists, technical problem to be solved in the utility model is, a kind of cast-in-place concrete stair is provided to mark time set shaped steel formwork, speed of application is fast, good control gangboard thickness, solve the problem of formwork difficulty of parameter tuning, ensure that construction quality, alleviate the labour intensity of workman.Can be used for single flight and two race stair.
For solving the problems of the technologies described above, technical solution adopted in the utility model is: a kind of cast-in-place concrete stair is marked time set shaped steel formwork, comprise elevating screw, step plate, mark time beam and reinforced bar support, described elevating screw is placed in set shaped steel formwork two ends platform, and it is vertically arranged; Described step plate is equidistant setting vertically, and it is fixedly connected with the beam of marking time be obliquely installed; Described reinforced bar support is fixedly connected on marks time beam between angle bar.
Further, mark time described in beam and vertical direction angle is 56 °-58 °.
Further, described step plate perpendicular separation is set to 160-170mm.
Further, beam of marking time described in is placed in 300mm place inside shaped steel template for stair mark time respectively.
The beneficial effects of the utility model are, cast-in-place concrete stair of the present utility model is marked time set shaped steel formwork, and speed of application is fast, good control gangboard thickness, solve the problem of formwork difficulty of parameter tuning, ensure that construction quality, alleviate the labour intensity of workman.Can be used for single flight and two race stair.

Below in conjunction with drawings and Examples, the utility model is described in more detail;
Fig. 1 be the utility model cast-in-place concrete stair mark time set shaped steel formwork plan view;
Fig. 2 is the sectional view of Fig. 1 along 1-1 face;
Fig. 3 is the 2 cage structure enlarged drawings of Fig. 2.
Detailed description of the invention
As shown in Figure 1, 2, 3, a kind of cast-in-place concrete stair is marked time set shaped steel formwork, comprises elevating screw 1, step plate 2, mark time beam 3 and reinforced bar support 4, and described elevating screw 1 is placed in set shaped steel formwork two ends platform, and it is vertically arranged; The vertically equidistant setting of described step plate 2, it is fixedly connected with the beam 3 of marking time be obliquely installed; Described reinforced bar support 4 is fixedly connected on marks time beam 3 between angle bar 5.
Further, beam 3 of marking time described in is 56 °-58 ° with vertical direction angle.Optimized angle of the present utility model is 57.34 °
Further, described step plate 2 perpendicular separation is set to 160-170mm.Preferred distance of the present utility model is 166.6mm.
Further, beam 3 of marking time described in is placed in 300mm place inside shaped steel template for stair mark time respectively.
Elevating screw 1 of the present utility model, mainly through the thickness regulating the length of screw mandrel to control step plate 2, makes it reach designing requirement..Step plate 2 and beam 3 of marking time are fixedly connected by welding, the same stairway width of step plate 2 size, and height is consistent with riser height. and reinforced bar support 4 can be good at playing a supporting role, and can be good at fixing step plate 2 and beam 3 of marking time simultaneously.
