Description

Technical Field

[0001] The utility model relates to the technical field of secondary erection support, and particularly relates to a novel secondary erection support system. Background Art

[0002] At present, the sizes of existing disk buckle beam brackets are relatively fixed. They are all sent to the site for erection after being installed. When erecting dense continuous beams, due to the fixed size and too short length of the beam brackets, it is very difficult to use them for supporting special positions. The secondary erection method requires the top support to be buckled in reverse. Due to size reasons, it cannot be used for low beams. When using keels for secondary erection, it can only be lapped on the top support, which greatly limits the use of secondary erection. That is, it is inconvenient to quickly connect and fix square steel pipes. Therefore, a secondary erection support system is needed to quickly connect and fix them. Summary of the Utility Model

[0003] In order to make up for the above deficiencies, the utility model provides a novel secondary erection support system, aiming to improve the problem that the keel cannot quickly assemble beam brackets of various sizes and the secondary erection platform, and it is inconvenient to quickly connect and fix square steel pipes.

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 , the present utility model provides a technical solution: a novel second erection support system, including a support frame 110. The support frame 110 is L-shaped and one end is hinged to a buckle plate 111. An embedded steel pipe 120 is installed inside the support frame 110. Square steel pipes to be connected are slidably sleeved on the outer sides of both ends of the embedded steel pipe 120. Hinge seats 112 are symmetrically and fixedly installed at the other end of the support frame 110. A fish-eye bolt 113 is hinged on the hinge seat 112. Positioning grooves cooperating with the fish-eye bolt 113 are symmetrically arranged on one side of the buckle plate 111. A flange nut 114 cooperating with the positioning groove is threadedly installed on the fish-eye bolt 113. The fish-eye bolt 113 is movably arranged in the positioning groove. A gap is arranged between the fish-eye bolt 113 and the inner wall of the positioning groove. The diameter of the flange nut 114 is larger than the width of the positioning groove.

[0022] In some specific implementation schemes, anti-slip pads 115 are symmetrically and fixedly installed between both sides of the inner wall of the buckle plate 111 and the support frame 110. The anti-slip pads 115 are elastic, and the thickness of the anti-slip pads 115 is between 2 - 4 mm, which improves the stability after the square steel pipe is extruded.

[0023] In some specific implementation schemes, one end of the buckle plate 111 is provided with a warped foot. The warped foot is L-shaped and the bottom end of the warped foot is arc-shaped, which effectively limits the flange nut 114 and prevents the flange nut 114 from slipping out of the limit groove during use, thus causing danger.

[0024] Please refer to Figure 4 and Figure 5, a support frame 110 is fixedly installed at the center of one side of the inner wall, a support frame 130 is fixedly connected to the inner wall of the embedded steel pipe 120, the support frame 130 is arranged at the center of the embedded steel pipe 120, and the support frame 130 is arranged on the same side as the anti-slip pad 115.

[0025] In some specific embodiments, a groove matching the support frame 130 is provided on the inner side wall of the support frame 110, the support frame 130 is slidably connected to the inner wall of the groove, and a plurality of springs 131 are fixedly installed between the bottom end of the inner wall of the groove and the support frame 130. The plurality of springs 131 are arranged at equal intervals between the bottom end of the inner wall of the groove and the support frame 130, which is convenient for the square steel pipe to rub against the inner wall of the support frame 110 when sleeving the embedded steel pipe 120, and also improves the stability during extrusion fixation, enabling the two sides of the square steel pipe to be simultaneously squeezed, thereby improving safety.

[0026] In some specific embodiments, limiting plates 132 are fixedly installed on both sides of the support frame 130, sliding grooves matching the limiting plates 132 are provided on both sides of the inner wall of the groove, guide rods 133 are symmetrically and fixedly installed between both sides of the inner wall of the sliding groove, the limiting plates 132 are slidably installed on the guide rods 133, and the limiting plates 132 are slidably connected to the inner wall of the sliding groove. The cooperation between the guide rods 133 and the limiting plates 132 improves the stability of the support frame 130 during movement.

[0027] Working principle: The two square steel pipes to be connected are respectively sleeved at both ends of the embedded steel pipe 120 and are attached to one side of the support frame 130. Rotate the buckle plate 111 until it is attached to one side of the square steel pipe, rotate the fish-eye bolt 113 until one end slides into the positioning groove, and then thread the flange nut 114 onto the fish-eye bolt 113 until one side is squeezed against the buckle plate 111. The buckle plate 111 rotates and squeezes the square steel pipe until it is fixed and then stops.

[0028] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
