Abstract

The utility model discloses a rotary staircase sampler in the field of assisted apparatus for building construction, which comprises a central steel pipe erectly arranged, a fixed sleeve arranged outside the central steel pipe and matched with the central steel pipe, a dial horizontally and coaxially arranged outside the fixed sleeve, a level fixed on the dial, a scale base sheathed outside the central steel pipe on the upper side of the dial, and a horizontal scale radially fixed outside the scale base. During mold construction, the central steel pipe is erectly arranged at the center point of the rotary staircase needing constructing the mold and is adjusted by the level to make the dial in the horizontal position, and the scale base can rotate around the central steel pipe by a certain angle, so that the circumference or an arc with a certain length can be conveniently divided into a plurality of equal parts, the horizontal scale can mark a line once after rotating by a certain angle, and the mold is constructed after setting out the line. By constructing the mold in the manner, the rotary staircase sampler has the advantages of convenient and rapid construction and high construction accuracy, and can improve the engineering quality and shorten the construction time.

Description

The spiral stairs applicator

Technical field

The utility model relates to a kind of auxiliary implement of housing construction, particularly a kind of setting-out utensil in the construction of spiral stairs formwork erection.

Background technology

In the prior art, the formwork erection construction of the spiral stairs of general industrial and covil construction, adopt taped measurement, the method that messenger wire weighs down, carry out the unwrapping wire of stair, find central point during unwrapping wire earlier accurately, a center steel pipe uprightly is set on central point, on the steel pipe of center, install and fix some supporting steel pipes, the certain angle that rotates in a circumferential direction between adjacent two supporting steel pipes differs the distance of one-level stair step simultaneously on short transverse, template can be bearing on the supporting steel pipe, when formwork erection, need in conjunction with spirit-leveling instrument, transit comes the division of adjustment level and angle, often will be through repeatedly adjusting, data are inaccurate, time-consuming, error is bigger, and many is to meet the requirements of by repair afterwards, bring bigger trouble to construction, influenced duration and quality.

The utility model content

The purpose of this utility model provides a kind of spiral stairs applicator, makes spiral stairs formwork erection quick construction convenient, the construction precision height.

In order to achieve the above object, the utility model has adopted following technical scheme: a kind of spiral stairs applicator, comprise a upright center steel pipe that is provided with, center steel pipe peripheral hardware has and the suitable fixed cover of center steel pipe, fixed cover is horizontally disposed with the index dial coaxial with fixed cover outward, be fixed with level on the index dial, the center steel pipe overcoat of index dial upside is equipped with rear sight base, and the rear sight base outer radial is fixed with horizontal ruler.

When formwork erection, the center steel pipe uprightly is installed on the central point of the spiral stairs that needs formwork erection,, makes its bubble placed in the middle by adjusting level, index dial is horizontal, rear sight base can turn an angle around the center steel pipe, like this can be easily the circular arc of circumference or certain-length be divided into some equal portions, and the horizontal ruler revolution can draw one time line after crossing certain angle, carry out formwork erection behind the unwrapping wire again, formwork erection in this way, quick construction is convenient, the construction precision height.Compared with prior art, the utility model can improve construction quality, simultaneously the reduction of erection time.

For making things convenient for the installation and removal of index dial, scale, described fixed cover, rear sight base all each free two half block are formed by connecting through coupling bolt, and index dial is also corresponding with fixed cover to be divided into two, and is connected as a single entity with corresponding half block respectively.By coupling bolt, index dial, scale can be installed on the steel pipe of center, also can unload easily.

Carry out unwrapping wire on the short transverse for making things convenient for, described horizontal ruler end is provided with the Vertical surveyors' staff perpendicular with horizontal ruler.Described horizontal ruler and Vertical surveyors' staff can be socketed to form by the multistage expansion link that has scale; The unwrapping wire that can adapt to multiple size like this.

Description of drawings

Fig. 1 is the utility model structural representation.

Fig. 2 is the vertical view of Fig. 1.

Fig. 3 is that the A-A of Fig. 1 is to view.

Wherein, 1 Vertical surveyors' staff, 2 horizontal rulers, 3 center steel pipes, 4 rear sight bases, 5 levels, 6 index dials, 7 fixed covers.

Embodiment

As figure, be the spiral stairs applicator, comprise a upright center steel pipe 3 that is provided with, center steel pipe 3 is outer to be provided with the fixed cover 7 suitable with center steel pipe 3, fixed cover 7 is outer to be horizontally disposed with the index dial 6 coaxial with fixed cover 7, be fixed with level 5 on the index dial 6, be set with rear sight base 4 outside the center steel pipe 3 of index dial 6 upsides, rear sight base 4 outer radials are fixed with horizontal ruler 2; Fixed cover 7, rear sight base 4 all each free two half block are formed by connecting through coupling bolt, and index dial 6 is also corresponding with fixed cover 7 to be divided into two, and is connected as a single entity with corresponding half block respectively; Horizontal ruler 2 ends are provided with the Vertical surveyors' staff 1 perpendicular with horizontal ruler 2; Horizontal ruler 2 and Vertical surveyors' staff 1 are socketed to form by the multistage expansion link that has scale.

During use, advanced line data calculates, and calculates according to the step number of stair step and the arc angle that revolved, and obtains arc angle φ, height h, the inner arc radius r of each grade step, outer arc radius R that each grade step of spiral stairs occupies.

During formwork erection, at first lay center steel pipe 3, can proofread and correct by level 5, guarantee that the center steel pipe is strict vertically, index dial, horizontal ruler are horizontal simultaneously, proofread and correct with line bob or transit, center steel pipe 3 is placed in the circle centre position of spiral stairs.Behind the leveling instrument, horizontal ruler 2 is placed the position of initially marking time, read initial circle reading, rotate horizontal ruler 2, the angle value that turns over is φ, and horizontal ruler 2 outer ends are pulled out and made its outer end is R to centre distance, obtains the position of radius r simultaneously; Vertical surveyors' staff 1 is pulled out height h, and Vertical surveyors' staff 1 upper end is the upper level position of marking time, and connects template supporting steel pipe with fastener according to this position on center steel pipe 3.And the like, the rotary scale seat 4 once more, and the angle value is φ, and the outer end length of horizontal ruler 2 is constant, and slider position also immobilizes, and by drawing Vertical surveyors' staff 1 on 2h, 3h, the 4h......, determines the 3rd, the 4th supporting steel pipe position of marking time.

After unwrapping wire finishes, can index dial 6, horizontal ruler 2 and Vertical surveyors' staff 1 be removed, remove with template when 3 of center steel pipes remain to form removal by coupling bolt.
