Description

Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to a template supporting structure. Background Art

[0002] Formwork is usually used in construction to support and contain plastic concrete, and to keep the plastic concrete in place until it solidifies to form a self-supporting concrete structure. Usually, the formwork needs to be supported by a socket-type disc-type steel pipe bracket before subsequent concrete pouring and curing work. The socket-type disc-type steel pipe bracket refers to a steel pipe bracket with a structural geometry unchanged system in which the vertical rods are connected by sockets and the horizontal rods are matched with the discs on the vertical rods by buckles, and the buckles are fixedly connected to the discs by pins to form a single-layer sheet structure. The socket-type discs currently on the market are single-layer sheet structures with weak deformation resistance. As the use time increases, the single-layer sheet-like discs are prone to deformation and affect the connection function, which has an adverse effect on the stability of the bracket.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0019] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:

[0020] like Figures 1 to 4As shown, a formwork support structure includes a crossbar 2, a vertical bar 1 and a buckle 3, wherein the crossbar 2 is fixedly connected to the vertical bar 1 through the buckle 3. The buckle 3 is provided with a tapered surface 32 that is symmetrical up and down, which increases the thickness of the buckle 3 and improves the strength of the buckle 3. The buckle 21 at one end of the crossbar 2 is provided with a slot 212 that matches the tapered surface 32. By using the cooperation between the tapered surface 32 and the slot 212, the external force on the buckle 3 is decomposed and offset in the vertical and horizontal directions, thereby improving the stability of the support structure and the anti-deformation ability of the buckle 3.

[0021] The buckle 3 is movably connected to the vertical rod 1. The vertical rod 1 is provided with a movably connected disc holder 13, and the buckle 3 is provided with a through hole 31 that matches the disc holder 13, and the bottom surface of the buckle 3 is in contact with the disc holder 13. The buckle 3 can rotate around the disc holder 13, which is convenient for assembling the buckle 21 and the buckle 3. The side of the buckle 3 is provided with an anti-skid pattern 33, which is used to facilitate the rotation of the buckle 3. A plurality of evenly spaced positioning openings 322 are provided on the circumference of the conical surface 32, and the buckle 21 is provided with a latch 22, which penetrates the buckle 21 and passes through the positioning openings 322. The side of the buckle 21 away from the latch 22 is fixedly connected to the cross bar 2 by welding, so as to ensure the connection strength between the buckle 21 and the cross bar 2. A plurality of evenly spaced positioning strips 321 are provided on the conical surface 32, and the side 211 of the buckle 21 is in contact with the positioning strips 321. The positioning strip 321 can be used to quickly confirm the relative position of the buckle 21 and the plate opening, thereby improving the assembly efficiency of the horizontal bar 2 and the vertical bar 1.

[0022] The vertical rod 1 passes through the plate support 13. A chassis 11 is provided at the bottom end of the vertical rod 1. The chassis 11 is integrated with the vertical rod 1, and the bottom surface of the chassis 11 contacts the working surface. The chassis 11 helps to disperse the pressure of the vertical rod 1 on the working surface, while increasing the bottom area of ​​the vertical rod 1 and maintaining the stability of the vertical rod 1.

[0023] The tray 13 includes a connecting tube 132 and a hand wheel 131. The inner wall of the connecting tube 132 is provided with threads. The vertical rod 1 is provided with a threaded section 12 that matches the connecting tube 132. The bottom of the connecting tube 132 is provided with a hand wheel 131. The hand wheel 131 is integrated with the connecting tube 132. The position of the tray 13 on the threaded section 12 of the vertical rod 1 is adjusted by rotating the tray 13, thereby fine-tuning the vertical position of the tray 13 to ensure that the horizontal degree of the cross bar 2 and the vertical rod 1 is maintained during assembly. The tray 13 can be fixed on the threaded section 12 by adding anti-loosening glue to the inner wall of the connecting tube 132.

[0024] The working principle of the specific implementation of the utility model is as follows: screw the disc holder 13 into the appropriate position of the threaded section 12 on the vertical rod 1, sleeve the disc buckle 3 on the disc holder 13, rotate the disc holder 13 so that the buckle 21 at one end of the cross bar 2 quickly cooperates with the disc holder 13, and fix the buckle 21 with the disc buckle 3 through the latch 22. The disc buckle 3 is provided with a conical surface 32, which increases the thickness and improves the strength of the disc buckle 3. The conical surface 32 increases the contact area between the disc buckle 3 and the buckle 21, and reduces the pressure on the disc buckle 3. The disc buckle 3 uses the conical surface 32 to decompose and offset the external force received, thereby improving the anti-deformation ability of the disc buckle 3.
