Description

Saddle-shaped double-curved concrete slab pouring support tooling

technical field

The utility model relates to a pouring support tool, in particular to a saddle-shaped hyperboloid concrete slab pouring support tool, which belongs to the technical field of building construction.

Background technique

It can be seen from space geometry that a hyperbola can be formed by rotating around an ellipse. For example, the ellipse equation at the zero point of the z-axis is:

$\frac{{\mathrm{<span\; class="notranslate">\; x</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}{{\mathrm{<span\; class="notranslate">\; a</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}<span\; class="notranslate">\; +</span>\frac{{\mathrm{<span\; class="notranslate">\; the\; y</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}{{\mathrm{<span\; class="notranslate">\; <figure-callout\; id="2"\; label="b"\; filenames="HDA00003071113800012.png,HDA00003071113800014.png"\; state="\{\{state\}\}">b</figure-callout></span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 1</span>}$

The hyperbolic equation at the zero point of the y-axis is:

$\frac{{\mathrm{<span\; class="notranslate">\; x</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}{{\mathrm{<span\; class="notranslate">\; a</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}<span\; class="notranslate">\; -</span>\frac{{\mathrm{<span\; class="notranslate">\; z</span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}{{\mathrm{<span\; class="notranslate">\; <figure-callout\; id="2"\; label="c"\; filenames="HDA00003071113800012.png,HDA00003071113800014.png"\; state="\{\{state\}\}">c</figure-callout></span>}}^{\mathrm{<span\; class="notranslate">\; 2</span>}}}<span\; class="notranslate">\; =</span>\mathrm{<span\; class="notranslate">\; 1</span>}$

When the above hyperbola is rotated along the ellipse, a hyperboloid can be formed. However, if the quadrilateral is projected upward directly below the hyperboloid, the curved surface cut out on the hyperboloid is a saddle-shaped hyperboloid.

With the increasingly rich and colorful architectural shapes, the saddle-shaped hyperboloid structure architectural design has been applied. The structure breaks through the previous architectural pattern and has a unique style of a pair of upturned corners and a pair of sunken corners. However, due to the complex shape of the saddle-shaped hyperboloid, the use of traditional formwork brackets to realize the construction of concrete slabs requires the production of curved skeletons, which not only requires high technical requirements for operators, it is difficult to ensure construction quality, and the work efficiency is extremely low, which cannot meet modern building construction progress requirements.

Utility model content

The purpose of the utility model is to propose a saddle-shaped hyperboloid concrete slab pouring support tooling with simple construction under the premise of ensuring the required curved surface shape, so as to lay the foundation for subsequent concrete pouring.

In order to achieve the above purpose, the basic structure of the saddle-shaped hyperboloid concrete slab pouring support tooling of the present invention is: a three-dimensional support system composed of a sweeping pole with a planar grid structure, a vertical pole and auxiliary supports, the vertical pole Set up on the intersection of the plane grid, the height of each vertical pole is determined according to the corresponding projection distance of the saddle-shaped hyperboloid to be built; The hyperboloid support beams distributed at intervals; the linear main flute bears and fixes the linear secondary flutes arranged in sequence at a predetermined density to form a hyperboloid space grid; the linear secondary flutes are covered with fixed panels to form a hyperboloid formwork.

On this basis, operations such as binding steel bars, forming hyperboloid pouring cavities, and concrete pouring can be carried out smoothly, and a saddle-shaped hyperboloid concrete slab with beautiful appearance can be obtained.

The panel of the utility model can be spliced by plywood strips, so that the profiling effect is better. The tops of the vertical poles are respectively fixedly connected to the linear main corrugations distributed at intervals through adjustable brackets, so the deflection can be eliminated through adjustment, so that the connection between the vertical poles and the main corrugations is more precise and stable.

The utility model cleverly utilizes the geometric characteristics that any point on the hyperboloid can extend out of two intersecting straight lines on the hyperboloid, and only conventional straight line building materials can be used to form a bracket tooling with a saddle-shaped hyperboloid on the top surface, without complicated drawing There is no need to manufacture curved components at all, the construction is very simple, the operator's skill requirements are not high, and it is easy to ensure that the concrete structure has a good appearance.

Detailed ways

Embodiment one

The saddle-shaped hyperboloid concrete slab pouring support tooling of this embodiment is made according to the following specific steps:

The first step is to measure and set out the line - since any point on the hyperboloid can extend out of two intersecting straight lines on the hyperboloid, it is possible to form the saddle-shaped hyperboloid concrete slab to be constructed with the help of solidworks and other computer drawing tools A three-dimensional geometric model, on which a spatial grid composed of intersecting spatial straight lines is established according to a predetermined accuracy, and then the spatial grid is vertically projected into a plane grid composed of intersecting plane straight lines. There is a one-to-one correspondence between projection intersection points in the lattice.

The second step is to set up the erection frame - set out the actual scale plane grid corresponding to the saddle-shaped hyperboloid space grid to be constructed on the construction ground, and build the sweeping pole 2 and the vertical grid corresponding to the real plane grid. The vertical pole 1 and the vertical pole 1 are erected on the intersection of the above-mentioned actual scale plane grid, and the height of each vertical pole is set according to the actual distance from the intersection point of the three-dimensional geometric model space to the corresponding intersection point of the projection (see Figure 1).

The third step is to build a support system—by overlapping the horizontal bar 3 and the oblique scissors brace (not shown in the figure) and other auxiliary supports, it forms a stable three-dimensional support system interrelated with the vertical bar 1 (see Figure 2).

The fourth step is to install the corrugated strips—connect the straight steel pipe building materials as the main flute 4 to the tops of the corresponding vertical poles 1 in sequence at the corresponding positions of the three-dimensional geometric model space grid lines to form a projection parallel interval Distribute hyperboloid braced beams. Then, the 50mm×50mm wooden square linear building materials as the secondary flute 5 are fixed on the main flute 4 in sequence at a predetermined density to form a hyperboloid space grid (see Figure 3).

The fifth step is to build the formwork——lay the plywood panel 6 with a fixed width of 50-200 mm on it in the direction obliquely intersecting with the second flute until a hyperboloid formwork is formed on the hyperboloid space grid (see Figure 4) .

In this way, the saddle-shaped hyperboloid concrete slab pouring support tooling with the structure shown in Figure 4 can be made: a three-dimensional support system composed of a sweeping pole 2 with a planar grid structure, a vertical vertical pole 1 and an auxiliary support crossbar 3 . The vertical poles 1 are erected at the intersections of the plane grids, and the heights of the vertical poles 1 are respectively determined according to the corresponding projection distances of the saddle-shaped hyperboloid to be built. The tops of the vertical poles 1 are fixedly connected to the spaced linear main corrugations 4 (see FIG. 2 ) through adjustable braces to form spaced spaced hyperboloid support beams. The straight line main flute 4 is responsible for fixing the straight line secondary flute 5 arranged in sequence with a predetermined density (see Figure 3), forming a hyperboloid space grid. The straight-line secondary flute 5 is covered with a panel 6 spliced by fixed plywood strips to form a hyperboloid formwork.

Afterwards, the formwork ribs are fixed on the edge of the hyperboloid formwork, the steel bars are bound, and the cover plate is built, and the concrete can be poured to obtain the required saddle-shaped hyperboloid concrete slab.

Practice has proved that the pouring support tooling of this embodiment is easy to manufacture, has good profiling effect, only needs conventional building materials, does not require high technical requirements for operators, helps to improve work efficiency, and meets the requirements of modern construction progress.
