Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to a screw rod hanging type beam template support beam structure. Background Art

[0002] At present, there are two conventional support methods for the beam template under the support beam, the beam under the vertical pole and the double-groove support beam placed on the beam side vertical pole connection plate. Both methods require additional adjustable support and main ribs, which are labor-intensive and material-intensive and have low construction efficiency. The beam under the vertical pole is widely used. Generally, two vertical poles are independently set under the beam to ensure the stability of the two ends of the supported main ribs. If one vertical pole is set, the beam and the plate should share the vertical pole, that is, the main rib can only be fixed with fastener steel pipes (limited load) and fastened to the beam side (under the plate) vertical pole or horizontal rod by fastener connection. Because the main rib of a single independent rod cannot be stable, ineffective work is increased. The adjustable support on the double-groove support beam cannot be reliably fixed, and the standard requirement that the adjustable support inserted into the steel pipe must not be less than 150mm is not met (the height of the steel bar is only 80-100), and the pin holes that should be installed on the horizontal and diagonal rods at the bottom of the beam are occupied, which directly affects the safety of the frame. At present, there are many patents for plate buckle racks that mainly propose solutions for this aspect, but reliability, convenience and construction efficiency cannot be coordinated. Utility Model Content

[0003] In view of the above problems, the purpose of the utility model is to provide a screw-hook hanging beam formwork support beam structure. The support beam is integrated with the main rib, breaking through the limitation of using steel pipe as the main rib fastener as the connection means, and is a light, efficient and simple support beam fixing method that does not occupy the position of the pin hole of the connecting plate at the bottom of the beam. The materials and components of the screw-hook frame of this application meet the JGT 503-2016 specification.

[0004] The specific technical solutions are as follows:

[0005] A screw-hook hanging type beam formwork support beam structure comprises a vertical pole, a connecting plate, a positioning pad, a screw, a curved cross arm and a double-slot support beam, a plurality of connecting plates are evenly arranged on the vertical pole, the vertical pole and the plurality of connecting plates are integrally formed, the positioning pad is arranged on the inner side above the connecting plate, the upper end of the screw passes through the connecting plate and the positioning pad in sequence, and a nut is used for limiting the position to realize the hanging of the screw, the lower end of the screw passes vertically through the curved cross arm, and a nut is used for limiting the position, the double-slot support beam is arranged between the two vertical poles, and the two ends are respectively fixed on the corresponding curved cross arms, and the height of the double-slot support beam can be adjusted by adjusting the position of the curved cross arm on the screw.

[0006] Furthermore, the positioning plate is arc-shaped, and is provided with an elliptical opening and a first pin hole. The first pin hole coincides with the second pin hole on the connecting plate. The upper end of the screw passes through the arc-shaped opening and the elliptical opening on the connecting plate in sequence, and a nut is used to limit the position to achieve the hanging of the screw. The opening of the positioning plate is elliptical in order to adjust the installation and ensure the verticality of the screw.

[0007] Furthermore, the upper parts of both ends of the double-groove joist are transversely beveled, and the lower wings of both ends are provided with cut angles.

[0008] The present invention provides an arc-shaped cross arm, which is integrally formed and has a first screw hole and a welding hole. The welding hole is located between the first screw holes. The lower end of the screw rod passes through the first screw hole and is limited by a nut to achieve the setting of the arc-shaped cross arm. The cut corners of the double-slot support beam are welded to the welding hole.

[0009] The present invention also provides another arc-shaped crossarm, which includes a steel sheet A and a steel sheet B. A steel sheet and B steel sheet are both provided with a second screw hole, one side of the steel sheet A is provided with a splicing block, and the steel sheet B is also provided with a third screw hole. One side of the steel sheet B is welded to the splicing block to achieve overall splicing of the arc-shaped crossarm. The lower end of the screw rod passes through the second screw hole and is limited by a nut to achieve the setting of the arc-shaped crossarm. The bolt passes through the third screw hole and the end of the double-slot joist, thereby achieving the fixation of the double-slot joist on the arc-shaped crossarm.

[0010] The screw holes of the curved crossarms are punched by mechanical stamping, which is conducive to standardized production.

[0011] Furthermore, a snap-on type clamping device for reducing the shaking of the double-slot joist is provided at the transverse bevels at both ends of the double-slot joist.

[0012] Furthermore, the snap-on clamping device includes a connecting section and a clamping section. The clamping section is a bent groove structure. The clamping section is clamped into the transverse bevel. The connecting section is inserted into the opening of the transverse bevel to achieve the connection between the snap-on clamping device and the double-slot support beam. The clamping between the double-slot support beam and the vertical pole is achieved by rotating the snap-on clamping device.

[0013] The technical effects of the utility model are:

[0014] Compared with the method of using uprights under the beam, the shear resistance of the connecting plate is utilized to eliminate the supporting uprights and diagonal bars at the bottom of the beam, reducing the material consumption and installation labor. Compared with the double-shaped steel joists directly placed on the connecting plate, the joists in this case are integrated with the main ribs of the formwork, and the joists are directly located at the bottom of the beam using screws, without the need for two adjustable supports. The connecting plate on the inner side of the beam in this solution has vacant pin holes, which do not occupy the eight pin holes of the connecting plate at the bottom of the beam, ensuring the longitudinal and transverse connection of the horizontal bars and vertical diagonal bars at the bottom of the beam, and does not occupy the horizontal scissor brace at the connecting plate at the bottom of the beam, thus maintaining the integrity of the highest position bracket at the bottom of the beam and ensuring the integrity and safety of the bracket.
