Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a steel template positioning device. Background Art

[0002] Steel formwork is a steel formwork used for concrete pouring and molding. Steel formwork is widely used in construction projects due to its multiple uses and beautiful concrete pouring and molding.

[0003] In the existing technology, steel formwork positioning tools are mostly a large number of steel bar screws that cooperate to clamp and position the steel formwork. The positioning measures do not have protective performance, and are troublesome to install and disassemble. The function is single, which reduces its practicality. When the length of the steel formwork splicing is long, additional positioning devices are required at the splicing point or in the middle of the steel formwork to fix it and resist the pressure of cement. The existing positioning devices have a single structure and poor versatility. For steel formwork structures of different widths, different formwork structures, etc., positioning devices of specific sizes are required, or additional gaskets are added to fix them, which is time-consuming, labor-intensive, and increases costs. Utility Model Content

[0004] The utility model provides a steel template positioning device to solve the problem of poor universality of the existing steel template positioning device.

[0005] To achieve the above purpose, the utility model provides the following solutions:

[0006] A steel formwork positioning device includes a crossbeam and limit members installed at both ends of the crossbeam and arranged in parallel, the limit members include a limit plate and a plurality of first telescopic members installed on the limit plates, the crossbeam is provided with a second telescopic member for adjusting the length of the crossbeam, the first telescopic member includes a screw hole opened on the limit plate and a screw installed in the screw hole.

[0007] The utility model changes the overall length of the positioning device through the second telescopic part, and then clamps and positions the steel template through the first telescopic part. The device can adapt to steel template structures of more widths. At the same time, multiple first telescopic parts can better contact the steel template and can adapt to more types of steel templates.

[0008] Furthermore, a rotating member is provided on a side of the screw rod away from the cross beam.

[0009] The length of the first telescopic member is adjusted by rotating the screw rod through the rotating member, with high adjustment accuracy and strong anti-extrusion ability.

[0010] Furthermore, the first telescopic member also includes a push plate, and the push plate is installed on a side of the screw rod away from the rotating member.

[0011] The diameter of the push plate is larger than the diameter of the screw, which increases the contact area between the push plate and the steel template and prevents the screw from directly contacting the steel template. Since the screw retracts and retracts by rotating, the place where it contacts the steel template is prone to wear, causing damage to the screw or the steel template.

[0012] Furthermore, the push plate is rotatably connected to the screw rod. When the screw rod rotates and retracts, the push plate can stop rotating with the screw rod, thereby reducing friction with the steel template. At the same time, when the screw rod and the steel template are not perpendicular, the push plate can better fit the steel template, increase the force-bearing area, and prevent damage to the steel template and the positioning device.

[0013] Furthermore, an anti-skid layer is provided on the push plate to increase the friction between the push plate and the steel template.

[0014] Furthermore, the second telescopic member includes a hollow sleeve and a connecting column that are arranged on the crossbeam and match each other. The side wall of the hollow sleeve is provided with a plurality of first through holes that penetrate the hollow sleeve, and the side wall of the connecting column is provided with a plurality of second through holes that penetrate the connecting column. The first through holes and the second through holes match each other and are connected by embedded pins.

[0015] The overall length of the crossbeam is changed by the expansion and contraction between the hollow sleeve and the connecting column, and the crossbeam is positioned by inserting a plurality of pins into the first through hole and the second through hole, so that the connection is firm.

[0016] Furthermore, the limiting member also includes a fixing column fixedly connected to the cross beam, the limiting member is provided with a groove for embedding the fixing column, the side wall of the fixing column is provided with a plurality of third through holes, the side wall of the groove is provided with a plurality of fourth through holes passing through the groove, the third through holes and the fourth through holes match each other and are connected by an embedded pin.

[0017] The overall length of the limiter is changed by the expansion and contraction between the fixing column and the groove, and is positioned by inserting a plurality of pins into the third through hole and the fourth through hole. The connection is firm and can adapt to the positioning and fixing work of steel formworks with longer lengths.

[0018] Furthermore, the plurality of the first telescopic members are arranged in at least two rows, and a spacing is provided between two adjacent rows of the first telescopic members.

[0019] For the first telescopic parts on the limit plate, they are distributed in a rectangular array, with the first telescopic parts in the same horizontal direction forming a row, and the first telescopic parts in the same vertical direction forming a column. At least two columns of first telescopic parts are provided to increase the lateral positioning and fixing width and area, and to adapt to the positioning and fixing work at the joint of the two steel formworks.

[0020] Furthermore, the limiting members at both ends of the beam are distributed in a mirror image.

[0021] One or more technical solutions provided by the utility model have at least the following technical effects or advantages:

[0022] (1) The utility model changes the overall length of the positioning device through the second telescopic member, and clamps and positions the steel template through the first telescopic member, thereby adapting to steel template structures of greater widths. At the same time, multiple first telescopic members can better contact the steel template, thereby adapting to more types of steel template structures;

[0023] (2) The push plate is in contact with the steel template, which increases the contact area between the push plate and the steel template, reduces wear, and the rotatably connected push plate can better fit the steel template;

[0024] (3) The length of the crossbeam is adjusted through the hollow sleeve and the connecting column, and the length of the limiter is adjusted through the fixing column and the groove, so that the positioning device has stronger adaptability. BRIEF DESCRIPTION OF THE DRAWINGS
