[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-4 As shown: A disc-lock type internal frame long top support includes a first square steel 1 and a second square steel 2 that are symmetrically arranged in the center, specifically long strips of galvanized steel. Both have a U-shaped cross-section and consist of upper and lower horizontal plates and vertical plates connecting the horizontal plates; the corresponding vertical plates of the first square steel 1 and the second square steel 2 are parallel to each other and fixed by fasteners.

[0022] The second square steel 2 is hinged at both ends to a third third steel 3. The third third steel 3 is also composed of horizontal plates on the upper and lower sides and vertical plates connecting the horizontal plates. The third third steel can be regarded as an extension of the end of the second square steel and is a separate structure. It is hinged and installed through a hinge, so that the third third steel can be flipped along the hinge side.

[0023] One end of the third square steel 3 is hinged to the second square steel 2, and the other end is detachably fixed to the end of the first square steel 1 by a fastener.

[0024] The long top support frame created by this invention is installed on a disc-type upright. The upright has a disc-shaped buckle fixed on its circumference. The bottom of the upright is an adjustable screw base with a sleeve. The upright has a hollow tube structure. The lower end is sleeved on the sleeve, and the upper end is sleeved on a screw-type top support. The top support has a U-shaped structure and is used to support a long strip of wooden support, which further supports the formwork for pouring.

[0025] The long top bracket has a disc buckle at the end that supports the upright, which is used to support the horizontally installed wooden brackets. The brackets can be evenly arranged to form a horizontal support surface.

[0026] This long top bracket has a first square steel and a second square steel, which form a groove between them. The corresponding end side groove is composed of a third third steel. The third third steel is hinged and has an openable structure. In the open state, it is easy to clamp to both sides of the upright. The bottom is supported by the disc buckle. After installation, the third third steel can also be fixed to the end of the first square steel by fasteners to lock the end side of the groove and prevent the long top bracket from coming off at the end.

[0027] After the pole system is installed, install the long top bracket. It can be installed from the side of the pole, which is convenient and quick, has good stability, and is easy to disassemble and reuse.

[0028] like Figure 2 As shown: A hinge sleeve 31 is provided at the end of the third square steel 3, and a hinge shaft 21 is provided at the corresponding end of the second square steel 2. A limit plate 32 is also fixed to the hinge side of the third square steel 3 for flipping and limiting its position relative to the end side of the second square steel 2. The hinge sleeve is fixed to the vertical plate of the third square steel through a connecting part, and the upper and lower ends of the hinge shaft are fixed to the upper and lower horizontal plates of the second square steel. The limit plate is an extension of the vertical plate at the end side of the third square steel and is used to limit the third square steel after it is flipped to be parallel with the first square steel, forming a clamping groove structure.

[0029] The vertical plates corresponding to the first square steel 1, the second square steel 2, and the third square steel 3 are all provided with through holes 11 for installing fasteners. The through holes are arranged in rows along the length of the vertical plates, with each through hole on the first square steel corresponding one-to-one with those on the second and third square steels. The fastener includes a sleeve 4 located between the first square steel 1 and the second square steel 2. The sleeve 4 has support rings on both sides for supporting the vertical plates of the corresponding square steels. Bolts 41 are installed inside the sleeve 4. The bolts pass through the through holes and are fitted onto the sleeve. The sleeve limits the distance between the two square steels, forming uniformly spaced grooves. The vertical plates corresponding to the square steels have multiple through holes, allowing adjustment of the fastener's installation position according to actual needs. Simultaneously, the installation position of the third square steel fastener can be adjusted according to the spacing between the disc-lock uprights to achieve the best fixing effect.

[0030] like Figure 3 As shown: An adjustable support block 5 is installed between the first square steel 1 and the second square steel 2. The support block 5 is square, with a round tube 51 fixed inside for installing a screw-type U-shaped top support 6. The support block is limited and installed in the groove between the two square steels, and can be moved and adjusted along the length of the square steel to adjust the installation position of the U-shaped top support. The bottom of the U-shaped top support has a screw rod for passing through the round tube. The screw rod is sleeved with a screw rod sleeve for rotating and adjusting the position, and is supported by the round tube, thereby adjusting the support height of the screw rod for installing a wooden support that is higher than the long top support frame. Height compensation can be achieved by installing the U-shaped top support. The support block 5 has a support plate 52 on the opening side for supporting the horizontal plates of the first square steel 1 and the second square steel 2 on both sides. The support block can be moved horizontally to adjust its orientation, and can also be disassembled for selective installation according to actual needs.
