[0002] The jacking bracket is mainly used to support concrete formwork during the construction of civil engineering projects, and plays a temporary supporting role. The specific requirements are that the strength, rigidity and stability can meet the force requirements. The commonly used jacking brackets on the market are of right-angle design, and the jacking screw is welded to the support plate. In order to ensure the welding quality and strengthen the corners, triangular stiffening plates are used for reinforcement at the welding points.

[0003] The Chinese utility model patent with publication number "CN213806574U" discloses a bracket support with adjustable angle. It is connected by a single set of connecting plates at the bottom of the support plate and the bolts at the top of the screw rod, so that a rotating structure is formed between the support plate and the screw rod, which can rotate with the angle of the template to increase the contact area between the support plate and the template.

[0004] At present, in the process of using the top support bracket, the waterproof board is closely attached to the primary support surface of the upper layer by relying on the support plate, but the flatness of the waterproof board is overly idealized, and the bulges and depressions of varying degrees on the waterproof board are ignored, resulting in poor laying quality of the waterproof board. Utility Model Content

[0005] The utility model provides a jacking bracket for laying waterproof boards, which solves the problem of poor laying quality of the waterproof boards caused by bulges and depressions of varying degrees on the waterproof boards.

[0014] The first threaded through hole and the second threaded through hole, which are coaxially arranged with their hole centers, are connected by an adjusting bolt.

[0015] Preferably, the two sleeves are fixedly connected via a crossbeam.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. In the utility model, multiple eccentric turn brackets are used. The rotation angles of the eccentric turn brackets are different, and the heights of the tops of the eccentric turn brackets from the threaded rods are different.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] An embodiment of a jacking bracket for laying a waterproof board 9 of the present invention is as follows: Figures 1 to 3 As shown, the device comprises: two parallel telescopic tube assemblies, a threaded rod 1 vertically passing through the two telescopic tube assemblies, and a plurality of eccentric rollers 2 sleeved on the threaded rod 1; the plurality of eccentric rollers 2 are located between the two telescopic tube assemblies;

[0027] The two telescopic tube assemblies are flush with each other; the threaded rod 1 is fixedly connected to the telescopic tube assembly; the eccentric rotating bracket 2 is movably connected to the threaded rod 1, and a fastening nut 7 is arranged on both sides of each eccentric rotating bracket 2, and the fastening nut 7 is threadedly connected to the threaded rod 1;

[0028] The eccentric support 2 abuts against the waterproof plate 9 .

[0029] In this embodiment, it should be noted that when the position of the eccentric turn support 2 needs to be moved, the fastening nuts 7 on both sides of the eccentric turn support 2 are rotated so that the fastening nuts 7 are away from the eccentric turn support 2, leaving space for the eccentric turn support 2 to move. When the eccentric turn support 2 needs to be completely fixed, the fastening nuts 7 on both sides are rotated in the opposite direction so that the fastening nuts 7 on both sides are tightly fitted to the side surfaces of the eccentric turn support 2 at the same time, and the eccentric turn support 2 is fixed by friction.

[0030] In this embodiment, it should be noted that the bottom end of the telescopic tube assembly is fixed to the working platform below the waterproof board 9 through the mounting seat 8. The eccentric turn bracket 2 mounted on the threaded rod 1 can rotate around the threaded rod 1 and can also move axially along the threaded rod 1. Since the rotation angle of the eccentric turn bracket 2 is different, the height of the top of the eccentric turn bracket 2 from the threaded rod 1 is different. Therefore, the eccentric turn bracket 2 can adapt to different degrees of bulging or depression. Manually rotate and move each eccentric turn bracket 1 until each eccentric turn bracket 2 is tightly against the waterproof board 9 above, and then tighten the fastening nuts 7 on both sides of the eccentric turn bracket 2 to fix the eccentric turn bracket 2, so as to ensure that the waterproof board 9 at the eccentric turn bracket 2 is tightly fitted to the primary support surface.

[0031] In this embodiment, it should be noted that the height of the telescopic tube assembly is adjustable. Therefore, when the positions of the two telescopic tube assemblies are fixed, the position of the eccentric support 2 can still be further adjusted in the height direction, which is more adaptable.

[0032] In this embodiment, the telescopic tube assembly includes a connecting portion 3 at the top and a telescopic tube 4 fixedly connected to the bottom end of the connecting portion 3 ; the connecting portion 3 is fixedly sleeved on the threaded rod 1 .

[0033] In this embodiment, the telescopic tube 4 includes an inserting tube 41 and a sleeve 42 sleeved outside the inserting tube 41 ; the bottom end of the connecting portion 3 is connected to the top end of the inserting tube 41 .

[0034] In this embodiment, the cross-sections of the insertion tube 41 and the sleeve 42 are both rectangular.

[0035] In this embodiment, it should be noted that the cross-sections of the cannula 41 and the sleeve 42 are both rectangular, and the rotation of the cannula 41 relative to the sleeve 42 is restricted by their own structures.

[0036] In this embodiment, the insert tube 41 is provided with a plurality of evenly spaced first threaded through holes 411, and the sleeve 42 is provided with a plurality of evenly spaced second threaded through holes 421. The spacing between the plurality of first threaded through holes 411 is the same as the spacing between the plurality of second threaded through holes 421. The first threaded through holes 411 and the second threaded through holes 421 have the same apertures, and at least one first threaded through hole 411 and one second threaded through hole 421 are coaxially arranged.

[0037] The first threaded through hole 411 and the second threaded through hole 421 are coaxially arranged and connected by an adjusting bolt 5 .

[0038] In this embodiment, it should be noted that the bottom of the sleeve 42 is fixedly connected to the mounting seat 8 , and the sleeve 42 is fixed on the working plane below the waterproof plate 9 through the mounting seat 8 .

[0039] In this embodiment, it should be noted that, without installing the adjusting bolt 5, the insert 41 can move up and down in the sleeve 42, that is, the height of the telescopic tube 4 is adjustable. When the different first threaded through holes 411 are completely aligned with the different second threaded through holes 421, the adjusting bolt 5 is simultaneously inserted into the aligned first threaded through holes 411 and the different second threaded through holes 421 to fix the height of the telescopic tube 4.

[0040] In this embodiment, it should be noted that the spacing between the multiple first threaded through holes 411 is the same as the spacing between the multiple second threaded through holes 421. There is a situation where the hole centers of the multiple first threaded through holes 411 are coaxial with the hole centers of the multiple second threaded through holes 421. Multiple adjusting bolts 5 can be installed to improve the supporting strength of the telescopic tube 4.

[0041] In this embodiment, the two sleeves 42 are fixedly connected via a crossbeam 6 .

[0042] In this embodiment, it should be noted that the two sleeves 42 are fixedly connected by a crossbeam 6 to improve the overall strength of the supporting bracket.

[0043] When this embodiment is actually used, the construction personnel observe the bulges and depressions on the waterproof board 9, select a suitable position, and fix the bottom of the top support bracket on the working plane below the waterproof board 9. The height of the telescopic tube 4 is adjusted by adjusting the bolt 5 to ensure that multiple eccentric turn supports 2 can abut against the waterproof board 9. Next, the eccentric turn support 2 on the threaded rod 1 is rotated and moved to tightly abut the eccentric turn support 2 against the bulge or depression of the upper waterproof board 9. The fastening nuts 7 on both sides of the eccentric turn support 2 are then rotated to fix the eccentric turn support 2 to ensure that the eccentric turn support 2 tightly supports the waterproof board 9, and the waterproof board 9 is tightly fitted with the initial support surface of its upper layer, thereby improving the laying quality of the waterproof board 9.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
