Description

Corner Fixing Fixtures for Concrete Formwork

1. Technical field:

The invention relates to construction equipment, in particular to a corner-fixing standard fixture for a concrete formwork.

2. Background technology:

Most of the cast-in-place concrete needs to build a formwork box to limit the scope and shape, and the three-dimensional structure in it has many angle-changing problems. In the prior art, the connection and fixation of the corner structure of non-metallic formwork is mostly realized by cutting materials on site, building support rods or pushing the adjacent formwork itself, which has the disadvantages of heavy materials, low utilization rate, and one-time use. The phenomenon is serious, the position of the diagonal is easy to change, and the movement and extrusion variables are large, resulting in high cost, poor effect, and difficult quality assurance.

3. Contents of the invention:

The purpose of the present invention is to address the above problems and deficiencies, to provide a corner fixing standard fixture for concrete formwork that is easy to make, easy to use, reusable, strong in rigidity, small in variable, easy to ensure the quality of the frame and improve the efficiency.

The purpose of the present invention is achieved through the following technical solutions:

The utility model relates to a concrete formwork corner fixing device, which includes formwork square tube corner corners, large holes, small holes, connecting rods and screws, and is characterized in that rectangular steel pipes are used to make square tube corner corners with equal side lengths, and the two corner sides Long sets large and small holes that are equidistant, spaced, opposite, and concentric.

The square tube corner is characterized in that it can be used for fixing the outer corner of the formwork, and can also be used for fixing the inner corner of the formwork.

The square tube corner is characterized in that when a plurality of square tube corners are used together in the same direction, they are connected by connecting rods made of angle steel or other long strip materials for combined application.

The square tube corner is characterized in that a single or combined square tube corner can also be applied to the cross-lap structure of the direction-changing formwork.

The square tube corner turn is characterized in that it can be made of angle steel or flat steel, and is individually applied to the inner or outer corner of the formwork.

The corner-fixing fixture of the concrete formwork of the present invention has the characteristics of easy manufacture, convenient use, repeated use, strong rigidity, small variable, easy universal use, etc., and also has the following significant advantages:

1. The corners are made of square steel pipes and the large holes and small holes are set. The connection and fixation with the formwork and the series fixing screws with the connecting rods are in a recessive state when they are combined. On the one hand, the same corner can be used for the inner corner formwork. Fixing, can also be used for fixing of outer corner formwork, at the same time will not affect each other when combined application.

2. The square tube corners, connecting rods and screws of the present invention are all made of reusable and recyclable metal materials, replacing common wood, more environmentally friendly and lower in cost.

3. Metal materials and the connection and combination methods in use have strong rigidity and small variables, which is conducive to quality assurance and improvement of construction.

4. The connection and combination in the application are all completed by screws, mainly based on flexible movements, avoiding violent demolition due to the combination of nails, making it easier to ensure the external quality of the concrete body, and at the same time reducing the labor intensity of construction personnel and improving Labor efficiency, safer and more convenient.

Figure 1 is a schematic cross-sectional view of the corner-fixed fixture of the concrete formwork.

Fig. 2 is a schematic side view of the corner-fixed fixture of the concrete formwork.

Fig. 3 is a schematic cross-sectional view of the corner-fixed fixture of the concrete formwork.

Fig. 4 is a schematic cross-sectional view of the combined application of the corner-fixed fixture of the concrete formwork.

In the figure: 1 template, 2 square tube corners, 3 large holes, 4 small holes, 5 connecting rods, 6 screws.

5. Specific implementation methods:

Below in conjunction with accompanying drawing, the present invention is described in further detail as follows:

As shown in Figure 1-3, the corner 2 of the square pipe is made of a rectangular steel pipe. Take two sections of equal length, one end is vertically cross-cut, and the other end is cut at a 45-degree oblique shape. Drill concentrically on one side wall in the same order as the equidistant Get the large hole 3, drill the small hole 4 on the other side wall, and weld the square tube angle 2 of 90 degree angle with 45 degree end to stubble welding.

As shown in Figure 4, the connecting rod 5 is made of angle steel, and the required length is intercepted, and the square tube angle turn 2 density is used in combination to drill holes with the same diameter as the small hole 4 on the corner surface of one side.

In application, if the inner corner or outer corner of the formwork box needs to be fixed, on the aligned formwork 1, place a line on the small hole 4 of the square pipe corner turn 2 and drill a hole, and insert a screw whose length does not exceed the thickness of the formwork 1 from the large hole 3 6 Fasten.

The height or width of the formwork box is too large, and the single formwork 1 cannot be covered. When it needs to be accumulated and applied and maintain a plane, the connecting rod 5 is used to combine the square tube corner 2 first, that is, on the other side of the square tube corner 2 of the fixed formwork 1 Attach the connecting rod 5, insert screws through the large hole 3, fix the required square tube corner 2 on the connecting rod 5, and then scribe and punch holes to complete the assembly of the template 1.

When its large formwork box has multiple direction changes, it should be dealt with in a fixed combination mode in the corner or outside the corner with the connecting rod 5 passing through the corner corner 2 of the square tube.

Except for the technical features described in the description, the present invention is the known technology of those skilled in the art.
