[0054] The accommodating space, that is, the accommodating cavity formed by the base 10, the telescopic part 20 and the force receiving part 30, is used to fill a medium to support the telescopic part 20 and the force receiving part 30, and the medium is usually a flowable filling material, which can be a liquid such as water, or a solid such as concrete, sand and the like, and the medium is preferably fine sand, which is lighter in weight than concrete.

[0055] The telescopic beam falling device according to the present application has the following beam falling process:

[0056] As shown in Figure 14 , Figure 15 The telescopic beam falling device 100 of the present application is placed on the bearing platform 400, the permanent support 300 is installed, and then the prefabricated beam body 200 is hoisted and placed on the top of the force receiving part 30 of the telescopic beam falling device 100.

[0057] After the beam body 200 is placed on the telescopic beam lowering device 100, the discharge part 4 is opened. Under the action of gravity and the pressure of the beam body 200 on the force receiving part 30, the fine sand filled in the accommodating space flows out through the discharge part, the force receiving part 30 and the telescopic part 20 slowly descend and shrink in turn, and the beam body 200 also slowly descends. The permanent support 300 is placed on the bearing platform, and the height of the permanent support 300 is higher than the height of the base 10. With the slow descent of the beam body 200, the beam body 200 is lowered to the support 300. The force receiving part 30 and the telescopic part 20 are telescoped into the base 10 in turn, and the beam lowering is completed. At this time, the height of the telescopic beam lowering device 100 after telescoping is lower than the support 300, so that the telescopic beam lowering device 100 can be taken out conveniently and can be recycled for multiple times.

[0058] Therefore, the telescopic beam lowering device 100 has the advantages that the telescopic structure is formed by the force receiving part 30, the telescopic part 20 and the base 10, the force receiving part 30 can be telescoped into the telescopic part 20, and the telescopic part 20 can be telescoped into the base 10, so that the telescopic beam lowering device 100 of different heights and widths can be designed, the beam lowering height is increased, the occupied space is reduced, the structure is simple, the installation and transportation are convenient, the accommodating space formed by the force receiving part 30, the telescopic part 20 and the base 10 is filled with the filling medium to complete the beam lowering, the stability is high, the supporting force is stable, and the construction cost is low.

[0059] According to an embodiment of the utility model, the base 10 is formed as a cavity structure with an open top, and the first limiting part 11 extends inward along the radial direction of the top edge.

[0060] In other words, referring to Figures 4 to 6 , the base bottom plate 14 and the surrounding part are formed as a cylindrical cavity structure with an open top, a plurality of reinforcing cloth 15 are arranged on the base bottom plate 14 to increase the structural strength of the base 10 and improve the stability of the telescopic beam lowering device 100. The first limiting part 11 extends inward along the radial direction of the top edge to limit the movement of the telescopic part 20 in the axial direction.

[0061] According to an embodiment of the utility model, the telescopic part 20 is formed as a cavity structure with an open top and bottom, the second limiting part 22 extends inward along the radial direction of the top edge of the telescopic part 20, and the second matching part 21 extends outward along the radial direction of the bottom edge of the telescopic part 20.

[0062] In other words, referring to Figures 7 to 9 , the telescopic part 20 is formed as a cavity structure with an open top and bottom, and the outer diameter size of the telescopic part 20 is slightly smaller than the inner diameter size of the first limiting part 11 of the top of the base 10. The second limiting part 22 extends inward along the radial direction of the top edge of the telescopic part 20, and the second matching part 21 extends outward along the radial direction of the bottom edge of the telescopic part 20. The outer diameter size of the second matching part 21 is slightly smaller than the inner diameter size of the base 10.

[0063] According to one embodiment of the utility model, the force receiving part 30 is formed as a cavity structure with an open bottom, and the third matching part 31 extends outward along the radial direction of the bottom edge.

[0064] In other words, with reference to Figures 10 to 12 , the force receiving part 30 is formed as a cavity structure with an open bottom, and the third matching part 31 extends outward along the radial direction of the bottom edge. The outer diameter of the third matching part 31 is slightly smaller than the inner diameter of the telescopic part 20.

[0065] Therefore, by arranging the first limiting part 11 extending inward along the radial direction of the top edge on the top of the base 10, the second matching part 21 extending outward along the radial direction of the bottom edge on the bottom of the telescopic part 20, the second limiting part 22 extending inward along the radial direction of the top edge on the top of the telescopic part 20, and the third matching part 31 extending outward along the radial direction of the bottom edge on the bottom of the force receiving part 10, the telescopic beam dropping device 100 is formed as a whole through the telescopic limitation of the limiting parts and the matching parts, which can ensure that the telescopic beam dropping device 100 does not disengage during use and can bear stress more evenly during beam dropping.

[0066] In some specific embodiments of the utility model, the discharge part 4 at the bottom of the side wall of the base 10 is at least two, and the two discharge parts 4 are arranged oppositely.

[0067] In other words, the number of the discharge part 4 at the bottom of the side wall of the base 10 is at least two, such as two, three, four, etc., and each discharge part is arranged oppositely in the circumferential direction of the base 10. Compared with only one discharge part, two or more discharge parts can solve the problem of low work efficiency caused by slow discharge of the filling medium and can avoid the problem that the telescopic part 20 or the force receiving part 30 is easy to lose balance during telescoping due to unbalanced discharge of the filling medium in the cavity structure. Meanwhile, the arrangement of multiple discharge parts 4 can also control the beam dropping speed by selectively opening or fully opening the discharge parts 4, which meets the possibility of various choices in the construction site.

[0068] In some specific embodiments of the utility model, the bottom position of the side wall of the telescopic part 20 is provided with at least two discharge parts 4, and the two discharge parts 4 are arranged oppositely.

[0069] In other words, in order to improve the beam dropping speed and accelerate the discharge of the filling material, the discharge part 4 can be arranged at the bottom position of the side wall of the telescopic part 20, and the number of the discharge part 4 is at least two, which can also be three, four, etc., and the multiple discharge parts 4 are arranged oppositely in the circumferential direction of the side wall of the telescopic part 20.

[0070] Therefore, the telescopic beam falling device can better control the beam falling speed and provide various discharge schemes for on-site construction.

[0071] In some specific embodiments of the present application, the discharge part 4 can open or prohibit the discharge of the filling medium.

[0072] In other words, the discharge of the filling medium can be controlled by opening or closing the discharge part 4. The preferred solution of the discharge part is to weld a nut on the inner side wall of the base 10 or the telescopic part 20 to facilitate the installation of the bolt rod. When the filling medium needs to be discharged, the bolt rod is opened to start the discharge. After the discharge is completed, the bolt rod is reinstalled to the nut, and the overall structure scheme has low cost and can be used multiple times.

[0073] In some specific embodiments of the present application, the position corresponding to the discharge part 4 on the second matching part 21 and the third matching part 31 is provided with a position avoiding part 5.

[0074] In other words, in order to facilitate the telescopic operation of the telescopic beam falling device 100 during the beam falling process, the position corresponding to the discharge part 4 on the bottom second matching part 21 of the telescopic part 20 and the bottom third matching part 31 of the stress receiving part 30 is provided with a position avoiding part 5, so that the telescopic part 20 and the stress receiving part 30 will not be interfered with during telescopic operation.

[0075] In some specific embodiments of the present application, the base 10 further comprises an injection hole 12 and a discharge groove 13.

[0076] Specifically, the injection hole 12 is arranged on the bottom surface of the base 10; the discharge groove 13 extends along the bottom surface of the base 10 from the middle to the outer periphery of the discharge part 4 in a downward trend.

[0077] In other words, as shown in Figures 4 to 6 The base 10 further comprises an injection hole 12 and a discharge groove 13. The injection hole 12 is arranged on the bottom surface of the base 10, and the injection hole 12 facilitates the injection of the filling medium such as fine sand. Before each use of the telescopic beam falling device 100, fine sand needs to be poured into the cavity structure through the injection hole 12 and filled densely, and the telescopic operation between the first limiting part 11 on the base 10, the second limiting part 22 on the telescopic part 20, the second matching part 21 and the third matching part 31 on the stress receiving part can ensure that the telescopic beam falling device does not come off during the sand pouring process. The extended shape of the telescopic beam falling device after filling is shown in Figures 1 to 3 .

[0078] In order to improve the beam falling speed in the beam falling process, improve the sand discharge efficiency, the discharge groove 13 is arranged at the bottom of the base 10, the discharge groove 13 extends along the bottom surface of the base 10 from the middle to the outer periphery of the discharge part 4 in a downhill trend, thereby forming a riverbed-like guiding effect extending from the middle to the periphery of the discharge part, facilitating the rapid discharge of fine sand in the telescopic beam falling device chamber.

[0079] In some specific embodiments of the utility model, the telescopic members 20 are multiple, and the multiple telescopic members 20 are connected in turn.

[0080] In other words, in order to adapt to beams of different heights, especially high beams, the telescopic members 20 can be provided in multiple numbers, and the multiple telescopic members 20 are connected in turn.

[0081] As shown in Figure 1 , Figure 2 When the number of telescopic members is 2, the upper group of telescopic members 20 is arranged in the lower group of telescopic members 20' (i.e. the second telescopic member) in the axial direction of the accommodating space, the second limiting part 22' of the lower group of telescopic members 20' (i.e. the second telescopic member) is matched with the second matching part 21 of the upper group of telescopic members 20 to limit the upper group of telescopic members 20 from separating from the lower group of telescopic members 20', and the first limiting part 11 of the base 10 is matched with the second matching part 21' of the lower group of telescopic members 20' (i.e. the second telescopic member) to limit the lower group of telescopic members 20' from separating from the base 10. The telescoping process can be referred to Figure 13 As shown in

[0082] In summary, the telescopic beam falling device 100 of the utility model forms a telescopic structure by arranging the force receiving member 30, the telescopic member 20 and the base 10, wherein the force receiving member 30 can be telescoped into the telescopic member 20, and the telescopic member 20 can be telescoped into the base 10, thereby not being limited by the height and width of the beam falling, and the telescopic beam falling device 100 of different heights and widths can be designed to increase the beam falling height; at the same time, the occupied space is reduced; the structure is simple, convenient to install and transport; the accommodating space formed by the force receiving member 30, the telescopic member 20 and the base 10 is filled with the discharge medium to complete the beam falling, which is stable, has stable supporting force and low construction cost.
