Description

Technical Field

[0001] This utility model belongs to the field of building formwork technology, and in particular relates to a variable cross-section steel rib building formwork. Background Technology

[0002] Variable cross-section formwork refers to building formwork used for casting or molding components whose cross-sectional dimensions and shapes change with length or position. It can adapt to the gradual or abrupt changes in the cross-section of the component and is commonly used in building engineering, such as variable cross-section beams and tapered columns in buildings.

[0003] When setting up a formwork with a variable cross-section, it is necessary to set up scaffolding top support. The arrangement of the support system is relatively complicated, and the operation is difficult when the position of the variable formwork needs to be adjusted. Therefore, we designed a variable cross-section steel rib building formwork, which uses three long screw rods in conjunction with the bracket for fixing the formwork installation. The position of the variable formwork can be flexibly adjusted, and the construction is simple, quick and easy with high adaptability. Utility Model Content

[0004] The purpose of this utility model is to provide a variable cross-section steel rib building formwork, which has the advantages of using a bracket with three long screw rods to fix the formwork installation, allowing for flexible adjustment of the position of the variable formwork, simple and quick construction, and high adaptability, so as to solve the above-mentioned technical problems.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A variable cross-section steel rib building formwork includes two fixed formworks and two adjustable formworks. The two adjustable formworks are located between the two fixed formworks. Two mountain-shaped brackets installed on the fixed formworks are provided on the opposite side of the two adjustable formworks. Two symmetrical connecting ribs are welded on the opposite side of the two adjustable formworks. The mountain-shaped brackets have elongated holes. Three long screw rods pass through the inner cavity of the elongated holes. A U-shaped hoop is welded to one end of the long screw rod and fixedly installed with the connecting ribs. Two washer nuts are threaded to the surface of the long screw rods. The washer nuts located on the inner side abut against the mountain-shaped brackets.

[0006] Preferably, three screws are welded to one side of the mountain-shaped bracket, and the mountain-shaped bracket is installed on the fixed template by the screws.

[0007] Preferably, a tie screw is provided through the U-shaped hoop, and three through holes for the tie screw to pass through are equally spaced on the connecting rib.

[0008] Preferably, the mountain-shaped bracket has two arc-shaped groove strips fixedly connected to the side away from the adjustable template, located on both sides of the elongated hole. The surface of the long screw rod is fitted with a retaining plate that engages with the arc-shaped groove strips, and one side of the retaining plate is in contact with the outer washer nut.

[0009] Preferably, the number of steel templates for fixing the template is two, and the two steel templates are connected by tie bolts.

[0010] The beneficial effects of this utility model are: 1. This utility model involves installing two mountain-shaped brackets on fixed templates on both sides, then passing three long screw rods connected to the connecting ribs through the inner cavity of the long holes on the mountain-shaped brackets and operating the washer nuts on the surface of the long screw rods to adjust the position of the washer nuts. This allows the three long screw rods to support and adjust the position of the adjustable template, thus achieving the purpose of using three long screw rods in conjunction with the fixed template to flexibly adjust the position of the variable template, making the construction simple and quick. 2. This utility model utilizes the combined use of the arc-shaped groove strip and the clamping plate. After the adjustable template is properly adjusted, the outer gasket nut causes the clamping plate to engage against the arc-shaped groove strip, increasing the support and limiting capacity of the long screw rod. This prevents the long screw rod from sagging due to inadequate tightening of the gasket nut, ensuring the stability of the locked state of the long screw rod and improving the support stability of the adjustable template.

[0013] In the following description, embodiments of the variable cross-section steel rib building formwork of this utility model will be described with reference to the accompanying drawings.

[0014] Figure 1-4This invention illustrates a variable cross-section steel rib building formwork according to an embodiment of the present invention. It includes two fixed formworks 1 and two adjustable formworks 2, with the two adjustable formworks 2 located between the two fixed formworks 1. The fixed formworks 1 consist of two steel templates connected by tie bolts. On opposite sides of each of the two adjustable formworks 2, two mountain-shaped supports 3 are mounted on the fixed formworks 1. Three screws 9 are welded to one side of each mountain-shaped support 3, which is then mounted on the fixed formworks 1 by the screws 9. On opposite sides of each of the two adjustable formworks 2, two symmetrical connecting ribs 4 are welded. The mountain-shaped supports 3 have elongated holes 5, through which three long screw rods 6 pass. One end of each long screw rod 6 is welded with a U-shaped clamp 7, which is fixedly installed to the connecting ribs 4. Tie bolts 10 are threaded through the U-shaped clamp 7. The connecting ribs 4 have evenly spaced... Three through holes 11 for the pull screws 10 to pass through. Two washer nuts 8 are threadedly connected to the surface of the long screw rod 6. The inner washer nut 8 abuts against the mountain-shaped bracket 3. Two arc-shaped groove strips 12 located on both sides of the long hole 5 are fixedly connected to the side of the mountain-shaped bracket 3 away from the adjustable template 2. A retaining plate 13 is fitted on the surface of the long screw rod 6 and engages with the arc-shaped groove strips 12. One side of the retaining plate 13 is in contact with the outer washer nut 8. Through the cooperation of the arc-shaped groove strips 12 and the retaining plate 13, after the adjustable template 2 is properly adjusted, the outer washer nut 8 causes the retaining plate 13 to abut against the arc-shaped groove strip 12 and engage, which increases the support and limiting capacity of the long screw rod 6, avoids the long screw rod 6 from falling due to the washer nuts 8 not being tightened properly, ensures the stability of the locked state of the long screw rod 6, and improves the support and stability effect of the adjustable template 2.

[0015] Working principle: When using this utility model, the U-shaped hoop 7 is installed on the connecting rib 4 through the inner cavity of the through hole 11 by the tie screw 10. The adjustable template 2 is placed between the two fixed templates 1. First, the inner washer nut 8 is screwed on the long screw rod 6. Then, the mountain-shaped bracket 3 is installed on the fixed template 1 by the screw 9. The long screw rod 6 on the U-shaped hoop 7 passes through the long hole 5 on the mountain-shaped bracket 3. Then, the outer clamping plate 13 and the washer nut 8 are installed on the long screw rod 6. By operating the washer nut 8 on the U-shaped hoop 7, the tilt and position of the adjustable template 2 can be adjusted. After the position is determined, the inner washer nut 8 is operated to abut against the mountain-shaped bracket 3. The outer washer nut 8 makes the clamping plate 13 engage with the arc-shaped groove strip 12, thereby locking the position of the adjustable template 2 and realizing the variable cross-section.

[0016] In summary, this variable cross-section steel rib building formwork, by installing two mountain-shaped supports 3 on the fixed formwork 1 on both sides, and then passing three long screw rods 6 connected to the connecting ribs 4 through the inner cavity of the long holes 5 on the mountain-shaped supports 3 and operating the washer nuts 8 on the surface of the long screw rods 6 to adjust the position of the washer nuts 8, thereby enabling the three long screw rods 6 to support and adjust the position of the adjustable formwork 2. This achieves the purpose of using three long screw rods in conjunction with the support for the fixed formwork installation, which allows for flexible adjustment of the position of the variable formwork, making the construction simple and quick.
