Description

A kind of stair step formwork with middle reinforcing device installed

technical field

The utility model belongs to the field of electric power construction, in particular to a stair step formwork with an intermediate reinforcement device installed.

Background technique

The traditional construction method of wooden formwork stairs is to fix the stair treads with iron nails and iron wires. The installation and removal procedures are cumbersome and the number of turnovers is small; the size of the concrete section is not easy to guarantee; the loss of wood and formwork is large; the shaped steel formwork stair formwork, The stair formwork is welded and processed by section steel and steel plate, which can effectively ensure the cross-sectional size of the staircase; the tower crane is required for hoisting during construction, and the use position is limited; the amount of section steel and steel plate invested at one time is large, and the cost is high.

Contents of the invention

The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a stair step formwork with simple structure, reasonable design, convenient use, reliability and durability, which is installed with an intermediate reinforcing device.

The utility model solves its technical problem and realizes by taking the following technical solutions:

A stair step formwork installed with an intermediate reinforcement device, the stair step formwork includes a riser formwork and side brackets, a plurality of riser formworks are evenly distributed and fixed between the side supports on both sides, and the feature is that: the riser formwork is horizontal The intervals are evenly distributed; two angle steel keels are installed at intervals in the middle of the multiple riser formworks between the side supports on both sides, and a reinforcement device is installed on the two angle steel keels corresponding to the outside of the multiple riser formworks ;

The specific structure of the reinforcement device includes support angle irons, brackets, upper adjustment rods, nuts and lower adjustment rods. The support angle irons contact the lower part of the riser formwork. An upper adjustment rod is welded and fixed. The upper adjustment rod is made with external threads. The upper adjustment rod passes through the gap between the angle steel keels upwards, and a nut is engaged and installed on the upper adjustment rod; There is an adjustment lever.

Moreover, embedded grooves are formed on the side brackets corresponding to the installation positions of the kick surface templates.

Moreover, two nuts are installed in series on the upper adjusting rod.

Moreover, the side supports are wooden keel and shear wall keel supports.

Advantage and positive effect of the present utility model are:

1. The angle steel keel in the utility model is the main stress-bearing part of the intermediate fixing device. It is transmitted through the adjustment rod and bears the horizontal force from the expansion of the kick surface formwork during pouring, thereby improving the rigidity of the formwork.

2. The utility model adopts the combination of steel and wood, which effectively saves material costs; the installation and disassembly is convenient, and the construction period is shortened; the template can be used repeatedly; the template has good rigidity and high installation accuracy, which can effectively ensure the effect of the staircase after forming.

detailed description

The utility model will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the utility model.

A stair step formwork with an intermediate reinforcement device. The stair step formwork includes a riser formwork 3 and side supports 4. The side supports are wooden keels and shear wall keel supports. The two side supports are obliquely fixed at the construction position. A plurality of riser formworks are evenly distributed and fixed at intervals between the side supports of the side brackets, and the plurality of riser formworks are used for positioning the step side risers of the stairs during construction.

In order to fix the riser formwork, embedded grooves are formed on the side brackets corresponding to the installation positions of the riser formwork.

The innovation of the utility model is:

In order to strengthen and control the verticality and rigidity of the stair formwork, it is explained in the direction shown in Figure 2, the long plate structure of the riser formwork in the longitudinal direction, and the transverse intervals of the riser formwork are uniform; Two angle steel keels 1 arranged at intervals are installed longitudinally in the middle of the face formwork, and a plurality of reinforcement devices 2 are evenly distributed on the two angle steel keels, and the plurality of reinforcement devices are respectively attached to the outside of a kick surface formwork;

The specific structure of the reinforcing device is shown in Figure 3, which includes a support angle iron 24, a bracket 23, an upper adjustment rod 21, a nut 22 and a lower adjustment rod 25. A bracket is fixed, and an upper adjustment rod is welded and fixed vertically on the upper end of the bracket. The upper adjustment rod is made with external threads. The upper adjustment rod passes through the gap between the angle steel keels upwards, and is engaged and installed on the upper adjustment rod. There are nuts; in order to enhance the fastening force, two nuts are installed in series on the adjusting rod, and the nuts and the bracket clamp the angle steel keel so that the reinforcement device and the angle steel keel are fixed;

In order to enhance the supporting force of the lower part of the kick surface formwork and prevent deformation, a lower adjustment rod 25 is installed horizontally on the lower part of the support angle iron. The lower adjustment rod is a Φ14 through-thread screw. Turning the lower adjustment rod can enhance the firm compression of the kick surface formwork. force.

The installation precision of the face plate of this embodiment is ±2mm.

Although the embodiments and accompanying drawings of the utility model are disclosed for the purpose of illustration, those skilled in the art can understand that various replacements, changes and modifications can be made without departing from the spirit and scope of the utility model and the appended claims. It is possible, therefore, the scope of the present invention is not limited to the contents disclosed in the embodiments and drawings.
