Abstract
The utility model relates to a stair step formwork frame. The stair step formwork frame comprises a pair of main keels, multiple pairs of riser formwork fixed assemblies and a plurality of secondary keels. The main keels are arranged above a stair bottom formwork in a paralleled mode along the extension direction of the stair bottom formwork. The riser formwork fixed assemblies are respectively arranged on the two main keels and distributed at intervals along the extension direction of the main keels. The secondary keels are transversely arranged above the main keels and distributed at intervals along the extension direction of the main keels. The stair step formwork frame achieves the purpose of guaranteeing forming quality of stair steps.
Description
Technical field
The utility model relates to a kind of stair step support for shuttering.
Background technology
Traditional stair riser template is only reinforced at two ends end to end, and being easy in work progress like this affects the Forming Quality of stair step because of the trampling or produce distortion when concrete is built of constructor.
Summary of the invention
The purpose of this utility model is to overcome the existing defects of prior art, and a kind of stair step support for shuttering that can guarantee the stair step Forming Quality is provided.
The purpose of this utility model is achieved through the following technical solutions: a kind of stair step support for shuttering is characterized in that: it comprise along the parallel a pair of main joist of being located at stair soffit formwork top of stair soffit formwork bearing of trend, be divided on two main joists and lay along main joist bearing of trend interval many to riser template fixation kit and many secondary joists crossing at the main joist top and lay along main joist bearing of trend interval; Each riser template fixation kit comprises vertical fixed bar and the top and the angled connecting rod that is fixedly connected with of fixed bar that arranges, bottom, be provided with a pair of fixture that is fixed with riser template upper and lower surface on described fixed bar, connecting rod is connected and fixed by connector and main joist.
Compared to prior art, the utility model has the advantage of: by the reinforcing of the utility model to stair riser template, can strictly control the accuracy rate of stair step size, effectively improve the pouring quality of stair step structure, simple in structure, be convenient to dismounting and can reuse.

Label declaration: 1 stair soffit formwork, 2 main joists, 3 riser templates, 4 riser template fixation kits, 4-1 fixed bar, 4-2 connecting rod, 5 secondary joists, 6 fixtures, 7 connectors, 8 vertical rods, 9 half space support for shuttering.
The specific embodiment
Below in conjunction with Figure of description and embodiment, the utility model content is elaborated:
The embodiment schematic diagram of a kind of stair step support for shuttering that provides for the utility model as shown in Figure 1 to Figure 3.
It comprises along the parallel a pair of main joist 2 of being located at stair soffit formwork 1 top of stair soffit formwork 1 bearing of trend, be divided on two main joists 2 and lay along main joist 2 bearing of trend intervals many to riser template fixation kit 4 and the many secondary joists 5 that cross at main joist 2 tops and lay along main joist 2 bearing of trend intervals; Each riser template fixation kit 4 comprises vertical fixed bar 4-1 and the top and the angled connecting rod 4-2 that is fixedly connected with of fixed bar 4-1 that arranges, bottom, be provided with a pair of fixture 6 that is fixed with riser template 3 upper and lower surfaces on described fixed bar 4-1, connecting rod 4-2 is connected and fixed by connector 7 and main joist 2.Described riser template 3 uniformly-spaced is laid between main joist 2 and stair soffit formwork 1, and riser template fixation kit 4 is welded and fixed by angle and the riser template 3 of formwork.
The both sides that are positioned at stair soffit formwork 1 are provided with the vertical rod 8 that is fixedly connected with secondary joist 5.Secondary joist 5 is supported be fixed in vertical rod 8, prevent that the absolute altitude error from appearring in riser template 3 under constructor's trampling.Described secondary joist 5 also can directly support on the shear wall that is fixed in two ends.
The two ends up and down of described main joist 2 are fixedly connected with the half space support for shuttering 9 of corresponding layer respectively.
Described clamping element 6 is angle bar, and described connector 7 is pipe thread.
