Description

Technical Field

[0001] The present application relates to the field of construction, and in particular to a foldable, quickly installed and disassembled support frame under a beam. Background Art

[0002] In the field of construction, the erection of under-beam supports is a complex and critical process. First, structural design and material preparation are required based on the type of beam and load. Second, the components must be assembled on site, including the installation of support columns, beams, horizontal supports, screws, support bases, etc. The multitude of structural components makes the erection process complicated. Third, inspection and testing are required. Because many traditional steel pipe fasteners are used in the erection of under-beam supports, these fasteners all have traditional drawbacks: such as fasteners not locking, lack of safety fasteners, rusted steel pipe materials, and steel pipe overlap lengths that do not meet regulatory requirements. Finally, after the project is completed, the supports need to be disassembled one by one according to the reverse steps of the erection. These tedious processes require a lot of manual labor, and the on-site assembly of components is time-consuming and labor-intensive, affecting construction efficiency and progress.

A second single vertical rod sleeve 24 is provided at each end of the second cross bar 21. The angle between the inclined bar 22 and the horizontal plane ranges from 15° to 25°. 17° is a preferred angle in this embodiment. It is not ruled out that the inclined bar 22 can also be set to other angles in actual application of this application.

[0043] like Figure 6 As shown, the single upright pole 3 is a telescopic pole composed of two or more sections of a rod body 31 , with a disc 32 provided at the upper end and the lower end of the rod body 31 .

[0044] like Figures 7 and 8 As shown, two groups of cross bar assemblies 4 are designed, one group is installed in the middle section of the single pole 3, and the other group is set at the bottom section of the single pole 3, which is used to provide strength for the entire support frame. At the same time, the cross bar assembly 4 cooperates with the single pole 3 to fold or unfold in conjunction with the first folding frame 1 and the second folding frame 2.

[0045] The cross bar assembly 4 includes a first rotating rod 41 and a second rotating rod 42 arranged below the first rotating rod 41. A third sleeve 43 is provided at the center of the first rotating rod 41, and a sleeve extension section 431 is provided on the lower surface of the third sleeve 43; a third sleeve 43 is also provided at the center of the second rotating rod 42, and the sleeve extension section 431 of the first rotating rod 41 is sleeved into the third sleeve 43 at the center of the second rotating rod 42, thereby realizing the rotational connection between the first rotating rod 41 and the second rotating rod 42.

[0046] Both ends of the first rotating rod 41 and the second rotating rod 42 are provided with a semicircular first arc cover plate 44, and the first arc cover plate 44 includes a second arc cover plate 45. After the first arc cover plate 44 and the second arc cover plate 45 are assembled, they form a sleeve shape and can be mounted on the outer diameter of the single vertical rod 3.

[0048] The foldable quick-install and dismantle support frame under the beam of the present application is assembled in the following manner before construction:

[0049] The shaft sleeve 23 of the second folding frame 2 is sleeved onto the shaft 14 of the first folding frame 1. The diagonal rod 22 of the second folding frame 2 is then positioned within the groove 13 of the first folding frame 1 and can rotate within the groove 13. The screw rod 51 of the sleeve jackscrew 5 is inserted into the jackscrew sleeve 17 and locked in place using the latch member 171. Two single-pole rods 3 are inserted into the first single-pole sleeves 15 at both ends of the first folding frame 1. Two single-pole rods 3 are inserted into the second single-pole sleeves 24 at both ends of the second folding frame 2. Take two groups of cross bar assemblies 4, one group is arranged in the middle section of the single upright pole 3, and the other group is arranged in the bottom section of the single upright pole 3. Each group of cross bar assemblies 4 includes a first rotating rod 41 and a second rotating rod 42. The semicircular first arc cover plates 44 at both ends of the first rotating rod 41 are fitted with the two single upright poles 3 under the first folding frame 1, and the single upright pole 3 is wrapped and fixed by the sleeve shape formed by the second arc cover plate 45 connected to the first arc cover plate 44; similarly, the sleeve extension section 431 of the first rotating rod 41 is sleeved into the third sleeve 43 at the center of the second rotating rod 42, and the semicircular first arc cover plates 44 at both ends of the second rotating rod 42 are fitted with the two single upright poles 3 under the second folding frame 2, and the single upright pole 3 is wrapped and fixed by the sleeve shape formed by the second arc cover plate 45 connected to the first arc cover plate 44; at this time, the first rotating rod 41 and the second rotating rod 42 rotate to intersect, and can rotate at the same angle as the first folding frame 1 and the second folding frame 2, to achieve the linked folding or unfolding of the entire frame structure.

[0050] The disc 32 on the upper section of the single pole 3 can prevent the first folding frame 1 and the second folding frame 2 and the structure thereon from accidentally sliding down. The disc 32 on the bottom section of the single pole 3 can prevent the cross bar assembly 4 from accidentally sliding down, providing support and protection for the entire support frame both during the erection process and during use.

[0051] According to the on-site construction size requirements, multiple bracket units are assembled in the same way as above. In the process of continuous construction, except for the outermost ends of the second folding frame 2 at the ends of the support frame (see Figure 1 In the figure 2a and 2b, the second pole sleeve 23 is directly connected to the single pole 3. The second pole sleeves 23 at both ends of the other second folding frames 2 are sequentially mounted on the upper ends of the first single pole sleeves 15 at both ends of the adjacent first folding frames 1 (see Figure 1), the first rotating rod 41 and the second rotating rod 42 are correspondingly set up between the front and rear bracket units, thereby realizing the rotation connection between all the first folding frames 1 and the second folding frames 2.

[0052] Through the above method, you can set up this application Figure 1 The foldable under-beam quick-install support frame shown can be folded or extended in the horizontal direction.

[0053] like Figure 11 As shown, when in use, four sets of the foldable quick-install support frames A under the beam (marked as A) described in this application are manufactured in advance according to the size of the beam template B (marked as B) at the construction site and transported to the site. The staff sequentially pulls apart the entire frame from one end of each set of foldable quick-install support frames A under the beam, and fits the extended top support 53 on the sleeve top screw 5 with the side under the beam template B, so that the installation of the entire support frame can be realized, while also taking into account the support of the support frame to the beam template B.

[0054] On the contrary, after the construction is completed, the extended top support 53 is removed, and the staff quickly installs one end of the support frame A from under each set of foldable beams to reversely compress and fold the entire frame to achieve the contraction of the frame and wait for the next turnover use.

[0055] The above are preferred embodiments of the present application. Other simple replacement implementation plans made on the basis of the above technical solutions of the present application are all protected contents of the present application.
