[0045] The following specific implementation manner will further illustrate the present invention in conjunction with the above-mentioned accompanying drawings. DETAILED DESCRIPTION

[0046] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments. Obviously, the described implementation is only a part of the implementation of the present invention, rather than all the implementations. Based on the implementation in the present invention, all other implementations obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention. Unless otherwise defined, all technical and scientific terms used in this article have the same meaning as those commonly understood by technicians in the technical field of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0047] See also Figure 1 , Figure 2 and Figure 3 The present invention provides a support device 100, which includes a first support tube 10, a second support tube 20 and a support pad 30. The second support tube 20 includes an inner hole 21, and the first support tube 10 can be telescopically accommodated in the inner hole 21. The support pad 30 includes a support pad body 31 and a baffle 32, the support pad body 31 includes two oppositely arranged surfaces 311 and a side surface 312 connected between the two surfaces 311, the support pad body 31 is provided with a slot 313 and a through hole 314, the through hole 314 passes through the two surfaces 311, the side surface 312 is recessed inward to form the slot 313, the slot 313 is connected to the through hole 314 and the slot 313 surrounds the through hole 314, and the baffle 32 can be movably accommodated in the slot 313. The support pad 30 is disposed at one end of the second support tube 20 away from the first support tube 10, and the inner wall of the through hole 314 is flush with the inner wall of the inner hole 21, the through hole 314 is connected to the inner hole 21, and the inner diameter D1 of the through hole 314 is the same as the inner diameter D2 of the second support tube 20. When the baffle 32 is received in the slot 313, the baffle 32 is used to close the through hole 314, and when the baffle 32 withdraws from the slot 313, the through hole 314 is connected to the outside.

[0048] During specific construction, one end of the support pad 30 is directly against a support surface (such as the ground or floor, not shown), and the other end is directly supported on a fixed top (not shown). During the concrete pouring stage, there will be some unsolidified concrete on the support surface or the fixed top. At this time, the baffle 32 is inserted into the groove 313, so that the slightly solidified concrete on the support surface cannot enter the inner hole 21 through the through hole 314. Even if the unsolidified concrete on the fixed top falls into the inner hole 21, the construction personnel can remove the baffle 32 from the groove 313 at this time, and because the inner wall of the through hole 314 is flush with the inner wall of the inner hole 21, the unsolidified concrete remaining in the inner hole 21 can be easily cleaned out (for example, the construction personnel can clean out the unsolidified concrete in the inner hole 21 with the help of a brush or by shaking). Furthermore, even if solidified concrete remains on the inner wall of the inner hole 21 , the concrete can be completely removed by slightly grinding, so the support device 100 designed as above is not easy to rust and corrode, which is beneficial to improving the safety of the support device 100 .

[0049] During specific recycling, it is necessary to reshape the deformed position of the second support tube 20 (for example, construction workers usually like to knock on the bottom of the second support tube 20 to adjust the verticality of the support device 100, which causes the bottom of the second support tube 20 to be easily deformed). By setting the support pad 30 to be sleeved on the second support tube 20, the recycling personnel can use a simple tool (for example, a round rod) to reach into the inner hole 21, and then use external force (for example, knocking) to complete the reshaping of the deformed second support tube 20.

[0050] In this embodiment, the support device 100 also includes a cushioning member 40, which includes a first support plate 41, a second support plate 42 opposite to the first support plate 41, and a cushioning tube 43 connected between the first support plate 41 and the second support plate 42. The first support plate 41 is connected to the support pad 30, and the second support plate 42 is used to support the first support plate 41 on the ground or connected to another cushioning member 40.

[0051] In this embodiment, the padding member 40 also includes a positioning column 44, which is arranged on the side of the first support plate 41 away from the padding tube 43, and the positioning column 44 is used to extend into the through hole 314 and the inner hole 21, so as to improve the stability of the connection between the padding member 40 and the second support tube 20.

[0052] In this embodiment, the support pad 30, the first support plate 41 and the second support plate 42 are all provided with fixing holes 34, and the fixing holes 34 of the support pad 30 are opposite to the fixing holes 34 of the first support plate 41, and the fixing holes 34 of the first support plate 41 are opposite to the fixing holes 34 of the second support plate 42, and the fixing holes 34 are used to pass through a screw rod, which cooperates with a nut to connect the support pad 30 and the first support plate 41 or the first support plate 41 of one of the raising components 40 and the second support plate 42 of another of the raising components 40.

[0053] During specific construction, for buildings with higher storeys, when the supporting height of the supporting device 100 is not enough, it is usually necessary to raise it below the supporting pad 30. At this time, the construction personnel can take out the baffle 32 from the groove 313, and then insert the positioning column 44 of the raising member 40 into the inner hole 21, and the first supporting plate 41 rests on the supporting pad 30, thereby increasing the supporting height of the supporting device 100.

[0054] In this embodiment, the inner wall and outer wall of the second support tube 20 and the outer surface of the support pad 30 are provided with an anti-rust paint layer (not shown), which can isolate external water vapor or concrete, further reducing the risk of rusting of the support device 100.

[0055] In this embodiment, the central axis O1 of the first support tube 10 coincides with the central axis O2 of the second support tube 20 .

[0056] In this embodiment, the support pad 30 is substantially rectangular, the through hole 314 is disposed in the central area of ​​the support pad 30 , and the second support tube 20 is fixedly connected to one of the surfaces 311 , for example, the second support tube 20 is welded to one of the surfaces 311 .

[0057] In other embodiments of the present invention, the shape of the support pad 30 may be other geometric shapes other than a rectangle, such as a circle, a prism, etc., and the through hole 314 is not limited to being set in the central area of ​​the support pad 30. For example, the through hole 314 may be set in the edge area of ​​the support pad 30, or in any other position except the edge area and the central area.

[0058] In this embodiment, the support pad 30 is recessed inwardly from a surface 311 of the second support tube 20 to form a plurality of grooves (not shown), and the grooves are symmetrically distributed on the surface 311. The support pad 30 also includes a plurality of rubber pads (not shown), each of which is partially accommodated in the groove and the other portion is exposed from the groove. By providing the rubber pads, the support pad 30 can be prevented from directly contacting the ground, thereby further reducing the risk of rust and corrosion of the support pad 30.

[0059] In this embodiment, the outer diameter R of the first support tube 10 is smaller than the inner diameter D2 of the inner hole 21 , so that the second support tube 20 can be sleeved outside the first support tube 10 .

[0060] In this embodiment, the first support tube 10 includes a plurality of positioning holes 11 spaced apart along the direction of the central axis O1, the positioning holes 11 penetrate the first support tube 10, and the second support tube 20 is provided with a positioning groove 22 at one end close to the first support tube 10, the positioning groove 22 penetrates the second support tube 20 and extends along the direction of the central axis O2, and the positioning groove 22 is arranged opposite to the positioning hole 11, the support device 100 also includes a limiting latch 50, the limiting latch 50 passes through the positioning groove 22 and the positioning hole 11, so that the first support tube 10 and the second support tube 20 are fixed, and the limiting latch 50 withdraws from the positioning groove 22 and the positioning hole 11, so that the first support tube 10 can be extended and retracted relative to the second support tube 20.

[0061] In this embodiment, a plurality of limit members (not shown) are protruding from the inner wall of the second support tube 20. The limit members are arranged at one end of the second support tube 20 close to the support pad 30. The limit members are used to prevent the first support tube 10 from sliding out of the inner hole 21, thereby increasing the practicality and safety of the support device 100.

[0062] In this embodiment, the second support tube 20 further includes a height adjustment seat 23, which is slidably sleeved outside the second support tube 20 along the central axis O2 direction, and the limit latch 50 abuts against the side of the height adjustment seat 23 away from the support pad 30. By adjusting the position of the height adjustment seat 23 on the second support tube 20, the distance that the first support tube 10 extends out of the second support tube 20 can be adjusted.

[0063] An embodiment of the present invention also provides a template combination (not shown), which includes a plurality of template components (not shown) and a plurality of supporting devices 100, wherein the first supporting tube 10 of the supporting device 100 is supported on the template component, and the supporting pad 30 of the supporting device 100 is supported on the ground.
