Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a detachable assembled construction elevator supporting device. Background Art

[0002] During the construction of high-rise buildings, construction elevators are essential construction equipment as vertical transportation tools. The layout of construction elevators must not only follow the principles of safety and economy, but also meet the requirements of convenience and strong operability during the construction process. The foundation of the construction elevator provides a stable support for the installation and operation of the elevator. It is mainly used in the hoistway construction elevator, using the foundation pit floor of the elevator shaft as the foundation of the construction elevator.

[0003] During the actual construction process, according to the construction plan, in order to ensure orderly construction on site, construction elevators are often set up in high backfill areas. The compaction degree of backfill in high backfill areas is difficult to control accurately. If the foundation of the construction elevator is placed directly on the backfill, after the construction elevator has been used for a long time, the backfill will easily settle at the installation site of the elevator foundation, which may easily lead to major safety hazards for the construction elevator. At the same time, after the construction elevator is used, the elevator foundation must also be dismantled after the construction elevator is dismantled. The dismantling of the elevator foundation is completely destructive, and it is difficult to reuse the elevator foundation. This part of the elevator foundation will be wasted, resulting in high construction costs. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a detachable assembled construction elevator support device to solve the problem that the construction elevator foundation is directly placed on backfill soil. After the construction elevator has been used for a long time, the backfill soil is very likely to settle at the installation site of the elevator foundation, and the construction elevator is prone to major safety hazards.

[0005] In order to achieve the above-mentioned object, the basic scheme of the present invention is as follows: a detachable assembled construction elevator support device comprises:

[0006] If the embedded unit is installed in the side wall;

[0007] A plurality of horizontal support columns, one end of which is detachably connected to the embedded unit;

[0008] A plurality of diagonal bracing rods are provided, wherein the diagonal bracing rods are located at the lower side of the horizontal supporting column, one end of the diagonal bracing rods is detachably connected to the embedded unit, and the other end of the diagonal bracing rods is connected to an end of the horizontal supporting column away from the embedded unit.

[0009] The technical principle of the present invention is: the side walls of the building cooperate with the embedded units, and after the horizontal support columns and the diagonal support rods are connected to the embedded units, they can provide stable support for the construction elevator, so that the support of the construction elevator is not affected by the settlement of backfill soil, thereby reducing the safety hazards of the construction elevator when in use.

[0010] When installing the detachable assembled construction elevator support device, an appropriate number of horizontal support columns and diagonal support rods can be selected according to the width occupied by the construction elevator, or the distance between two adjacent horizontal support columns can be adjusted. In this process, several embedded units are embedded in the side wall according to the installation position of the construction elevator, so that the installed horizontal support columns and diagonal support rods can fully and stably provide basic support for the construction elevator.

[0011] Further, the embedded unit includes:

[0012] Positioning installation plate, the positioning installation plate is pre-buried and installed on the side wall;

[0013] If there is an embedded column, the embedded column horizontally passes through the positioning installation plate, and the middle part of the embedded column is fixedly installed on the positioning installation plate, one end of the embedded column is located outside the side wall, and the embedded column and the positioning installation plate are both detachably connected to the horizontal support column or the diagonal support rod.

[0014] Through the above-mentioned arrangement, after the installation of the detachable assembled construction elevator support device is completed, a number of embedded columns and positioning installation plates can transfer the pressure they are subjected to to the side walls more evenly, so that the embedded columns and positioning installation plates can provide stable support for the horizontal support columns and the diagonal support rods. At the same time, the embedded columns are also easy to match and connect with the horizontal support columns or the diagonal support rods, and it is also convenient to disassemble the horizontal support columns or the diagonal support rods and the embedded columns, so that the detachable assembled construction elevator support device is easier to disassemble and use on other construction sites, thereby reducing construction costs.

[0015] Furthermore, the embedded column is hollow, and an anti-blocking end cap is provided on one end of the embedded column close to the side wall; an external thread is provided on the outer wall of the embedded column, and the embedded column is threadedly connected to the positioning installation plate.

[0016] Through the above-mentioned arrangement, the anti-blocking end cover can seal the end of the embedded column to prevent concrete from entering the embedded column during side wall construction, and it is also convenient for the end of the embedded column to be matched and connected with the horizontal support column or the diagonal support rod; at the same time, since the embedded column is threadedly connected to the positioning installation plate, it is convenient to locate the length of the two ends of the embedded column at both sides of the positioning installation plate, and then the length of the embedded column embedded in the side wall can be finely controlled, so that the depth of the embedded column and the positioning installation plate installed in the side wall can be adjusted, and the installation strength can also be adjusted; when the detachable assembled construction elevator support device is disassembled after use, the embedded column is screwed, and a single embedded column is separated from the side wall and the positioning installation plate in turn. The removal of the embedded column is labor-saving and convenient, and it is also convenient to pry off the positioning installation plate on the side wall for reuse.

[0017] Furthermore, it also includes a connecting unit located at the end of the horizontal support column or the diagonal support rod, and the connecting unit includes:

[0018] A connecting plate, the surface of which can be parallel to and opposite to the surface of the positioning and mounting plate, the connecting plate is provided with a through hole for the embedded column to pass through, and the connecting plate is fixedly connected to the end of the horizontal support column or the diagonal brace;

[0019] The locking nut can be threadedly connected with the external thread of the embedded column, and the locking nut can be abutted against the connecting plate.

[0020] Through the above-mentioned arrangement, the connecting plate can cooperate with the positioning mounting plate, and the locking nut can cooperate with the embedded column, so that the connecting plate and the positioning mounting plate can cooperate tightly, so that the ends of the horizontal support column or the diagonal support rod can be stably installed on the positioning mounting plate and the embedded column, and the disassembly and assembly between the horizontal support column or the diagonal support rod and the positioning mounting plate and the embedded column are convenient.

[0021] Furthermore, the connecting unit also includes a cover plate, which is provided with an opening for the horizontal support column or the diagonal support rod to pass through. The end face of the cover plate can be abutted against the side of the connecting plate away from the positioning mounting plate, and a plurality of positioning rods are provided on the side of the cover plate close to the positioning mounting plate. The positioning rods can be embedded and installed in the embedded columns.

[0022] Through the above-mentioned arrangement, when installing the cover plate, the cover plate moves to the end close to the embedded column, and the positioning rod is stably inserted into the embedded column to support and reinforce the embedded column. At the same time, the cover plate is stably guided and buckled onto the connecting plate, and the cover plate can cover all the embedded columns, positioning rods and locking nuts, so that the embedded columns, positioning rods and locking nuts are protected and not easily covered by dust or affected by mud and sand, which facilitates the subsequent disassembly of the detachable assembled construction elevator support device.

[0023] Furthermore, it also includes an adjustment and reinforcement unit, which includes:

[0024] A threaded rod, one end of the threaded rod horizontally passing through one of the horizontal support columns, and the other end of the threaded rod horizontally passing through an adjacent horizontal support column;

[0025] An adjusting nut is threadably connected to the threaded rod, and the adjusting nut can abut against a side wall of the horizontal supporting column.

[0026] Through the above arrangement, when installing the adjustment reinforcement unit, the threaded rod passes through the middle part of the two flat support columns, and the adjusting nut is screwed onto the end of the threaded rod and abuts against the middle part of the flat support column, so that the threaded rod is fixed between the two flat support columns, and the two flat support columns are reinforced to improve the supporting force between the two flat support columns; the two adjacent horizontal support columns can be connected by controlling the position of the adjusting nut on the threaded rod to adapt to horizontal support columns with different spacings, and also to adapt to the foundation supports of construction elevators with different widths; when disassembling, the disassembly between the adjusting nut and the threaded rod is also convenient.

[0027] Furthermore, a groove is horizontally arranged at the top of the horizontal support column, and the groove is open on the side away from the side wall. An extension plate is horizontally installed in the groove of the horizontal support column. The extension plate is horizontally adjustable and installed in the groove of the horizontal support column. The extension plate can be fixedly connected to the horizontal support column, and the upper surface of the extension plate is coplanar with the upper surface of the horizontal support column.

[0028] Through the above-mentioned arrangement, the groove can limit the installation of the extension plate, so that the extension plate can extend beyond the horizontal support column, and the support range of the construction elevator can be expanded, so that the support range of the detachable and assembled construction elevator support device is more matched with the support range required by the construction elevator, and the support of the construction elevator is also more stable.

[0029] Furthermore, a number of overlapping connecting holes are vertically arranged on the extension plate and the horizontal support column, and bolts are provided through the connecting holes. The bolts are fixedly connected to the extension plate, and the lower side of the bolts is threadedly connected with a fixing nut that can be abutted against the lower side of the horizontal support column, and the upper end surface of the bolts is coplanar with the upper surface of the extension plate.

[0030] Through the above-mentioned arrangement, when adjusting the position of the extension plate, loosen the fixing nut on the lower side of the bolt, remove the extension plate on the horizontal support column, and move the extension plate to the right so that some of the connecting holes on the extension plate coincide with the connecting holes on the horizontal support column again, and the lower end of the bolt is again embedded in the connecting holes of the horizontal support column. At this time, screw the fixing nut onto the bolt to fix the extension plate on the horizontal support column. The position of the extension plate can be easily adjusted and the installation is reliable.

[0031] Furthermore, the longitudinal section profile of the groove is in a "convex" shape, and the longitudinal section profile of the extension plate is also in a "convex" shape that is embedded in and abuts against the groove of the horizontal support column.

[0032] Through the above arrangement, when the extension plate supports the construction elevator, the side edges of the extension plate stably abut against the side walls of the groove of the horizontal support column, so that the extension plate is stably supported, and the groove can guide the horizontal movement of the extension plate.

[0033] Furthermore, a rack is integrally formed on the side of the extension plate; an installation cavity is provided in the end of the horizontal support column away from the side wall, and a gear meshing with the rack is rotatably installed in the installation cavity of the horizontal support column, and a dial wheel is rotatably installed on the lower surface of the horizontal support column, and the dial wheel passes through the horizontal support column and is coaxially fixedly connected to the gear.

[0034] Through the above arrangement, when the dial wheel rotates forward, the dial wheel drives the gear to rotate forward synchronously, the gear engages with the rack, and then drives the extension plate to extend horizontally along the groove to the outside of the groove; when the dial wheel rotates reversely, the dial wheel drives the gear to rotate reversely synchronously, and then drives the extension plate to fold horizontally along the groove to the inside of the groove, so that the folding control of the extension plate is convenient and the operation is more labor-saving.

[0043] like Figure 1and 2 As shown, the connecting unit includes a connecting plate 30, a plurality of locking nuts 301 and a cover plate 302. The surface of the connecting plate 30 can be parallel to and opposite to the surface of the positioning and mounting plate 10. The connecting plate 30 is provided with through holes for a plurality of embedded columns 20 to pass through. The connecting plate 30 is integrally formed with the end of the horizontal support column 40 or the diagonal support rod 50; the locking nut 301 can be threadedly connected to the external thread of the embedded column 20, and the locking nut 301 can be abutted against the connecting plate 30; at the same time, the cover plate 302 is provided with an opening 312 for the horizontal support column 40 or the diagonal support rod 50 to pass through, the end face of the cover plate 302 can be abutted against the side of the connecting plate 30 away from the positioning and mounting plate 10, and a plurality of positioning rods 303 are provided on the side of the cover plate 302 close to the positioning and mounting plate 10, and the positioning rods 303 can be embedded and installed in the embedded column 20.

[0044] like Figure 1 and 2 As shown, the adjustment reinforcement unit includes a threaded rod 601 and an adjustment nut 601. The left end of the threaded rod 601 horizontally passes through the horizontal support column 40 on the left, and the right end of the threaded rod 601 horizontally passes through the horizontal support column 40 on the right; the adjustment nut 601 is threadedly connected to the threaded rod 601, and the adjustment nut 601 can be abutted against the side wall of the horizontal support column 40.

[0045] At the same time, if Figure 1 , 2 As shown in FIG. 3 , a groove 401 is horizontally arranged at the top of the horizontal support column 40, and the side of the groove 401 away from the side wall is in the shape of an opening 312. An extension plate 403 is horizontally installed in the groove 401 of the horizontal support column 40. The extension plate 403 is horizontally adjustable and installed at the groove 401 of the horizontal support column 40. The extension plate 403 can be fixedly connected to the horizontal support column 40, and the upper surface of the extension plate 403 is coplanar with the upper surface of the horizontal support column 40; as shown in FIG. Figure 3 As shown, a plurality of overlapping connecting holes 404 are vertically arranged on the extension plate 403 and the horizontal support column 40, and bolts 402 are penetrated through the connecting holes 404. The bolts 402 are welded to the extension plate 403, and the lower side of the bolts 402 is threadedly connected with a fixing nut 406 that can be abutted against the lower side of the horizontal support column 40, and the upper end surface of the bolt 402 is coplanar with the upper surface of the extension plate 403.

[0046] When the detachable assembled construction elevator support device in this embodiment is in use, a suitable number of horizontal support columns 40 and diagonal support rods 50 can be selected according to the width occupied by the construction elevator, or the distance between two adjacent horizontal support columns 40 can be adjusted, so that the installed horizontal support columns 40 and diagonal support rods 50 can fully and stably provide basic support for the construction elevator.

[0047] When the width occupied by the construction elevator is wider, when 2 or more horizontal support columns 40 are selected, the threaded rod 601 and the adjusting nut 601 can be used to stagger and connect two adjacent horizontal support columns 40, so that several horizontal support columns 40 are connected to each other to form a supporting structure of the overall structure, so that the support of the construction elevator is stable; when it is necessary to adjust according to the support width required by the construction elevator, first control the pre-installation installation position of the positioning mounting plate 10 in the two adjacent embedded units and the pre-installation gap between the two adjacent positioning mounting plates 10 to achieve the preset gap between the two adjacent horizontal support columns 40. When the threaded rod 601 and the adjusting nut 601 are used to reinforce the horizontal support column 40, the two adjacent horizontal support columns 40 can be connected by controlling the position of the adjusting nut 601 on the threaded rod 601 to adapt to horizontal support columns 40 with different spacings, and also to adapt to the foundation support of construction elevators with different widths.

[0048] When installing the detachable assembled construction elevator support device, when constructing the side wall, according to the installation position of the construction elevator, the positioning installation plate 10 and several embedded columns 20 are installed on the side wall, and the left side of the positioning installation plate 10 and the left end of the embedded column 20 are both embedded in the side wall. At this time, the installation position and number of the embedded column 20 can be selected according to the installation position of the horizontal support column 40 or the diagonal brace rod 50. The installation position of the embedded column 20 can avoid the position at the left end of the horizontal support column 40 or the diagonal brace rod 50, so that the embedded column 20 can effectively cooperate with the subsequent connecting plate 30 and the locking nut 301; in the above process, the horizontal position and vertical position between the remaining positioning installation plates 10 and the adjacent positioning installation plates 10 must also be accurately controlled, so that the adjacent horizontal support columns 40 are located on the same horizontal plane, and the diagonal brace rod 50 and the corresponding horizontal support column 40 are located on the same vertical plane, which can provide balanced and stable support for the subsequent construction elevator.

[0049] When installing the horizontal support column 40 and the diagonal support rod 50, the connecting plate 30 on the left end of the horizontal support column 40 or the diagonal support rod 50 overlaps with the right side of the positioning and mounting plate 10, and the right end of the embedded column 20 passes through the through hole on the connecting plate 30 in turn to achieve preliminary limiting of the installation of the horizontal support column 40 and the diagonal support rod 50, and then the locking nut 301 is screwed to the outer wall of the embedded column 20, and the locking nut 301 is tightly pressed against the right side of the connecting plate 30 to achieve stable installation of the ends of the flat support column and the diagonal support rod 50 to the embedded column 20 and the positioning and mounting plate 10; then the threaded rod 601 is passed through the middle part of the two flat support columns, and the adjusting nut 601 is screwed to the end of the threaded rod 601 and pressed against the middle part of the flat support column, so that the threaded rod 601 is fixed between the two flat support columns, the space between the two flat support columns is reinforced, and the supporting force between the two flat support columns is increased.

[0050] The cover plate 302 on the end of the horizontal support column 40 is moved horizontally, and the cover plate 302 simultaneously drives the positioning rod 303 to horizontally approach the right end of the embedded column 20, and the positioning rod 303 is stably inserted into the embedded column 20 to support and reinforce the embedded column 20. At the same time, the cover plate 302 is stably guided and buckled onto the connecting plate 30, and the cover plate 302 can cover all the embedded columns 20, the positioning rod 303 and the locking nut 301, so that the embedded columns 20, the positioning rod 303 and the locking nut 301 are protected and not easily covered by dust or affected by mud and sand, which is convenient for the subsequent disassembly of the detachable assembled construction elevator support device.

[0051] The extension plate 403 can then be adjusted to extend the length of the end of the horizontal support column 40 according to the support range required for the construction elevator in the length direction. At this time, the fixing nut 406 on the lower side of the bolt 402 is loosened, and the extension plate 403 on the horizontal support column 40 is removed. The extension plate 403 moves to the right, so that part of the connecting hole 404 on the extension plate 403 coincides with the connecting hole 404 on the horizontal support column 40 again, and the lower end of the bolt 402 is again embedded in the connecting hole 404 of the horizontal support column 40. At this time, the fixing nut 406 is screwed and fixed to the bolt 402 to fix the extension plate 403 on the horizontal support column 40. The extension plate 403 also extends outside the horizontal support column 40, so that the extension plate 403 can fully support the lower edge of the construction elevator, so that the support range of the detachable assembled construction elevator support device is more matched with the support range required for the construction elevator, and the support of the construction elevator is also more stable.

[0052] In the above process, the side walls of the building cooperate with the detachable assembled construction elevator support device to provide stable support for the construction elevator, so that the support of the construction elevator is not affected by the settlement of backfill soil, thereby reducing the safety hazards of the construction elevator when in use.

[0053] When the construction elevator is used up, when the detachable assembled construction elevator support device is disassembled, the fixing nut 406 is removed so that the extension plate 403 moves back and overlaps in the groove 401, so as to realize the folding of the extension plate 403; then the adjusting nut 601 and the threaded rod 601 are removed to separate the horizontal support columns 40; the positioning plug rod 303 at the embedded column 20 is pulled out by controlling the cover plate 302, and then the locking nut 301 can be screwed and removed to separate the embedded column 20 from the connecting plate 30, and the horizontal support column 40 and the diagonal support rod 50 are separated from the positioning mounting plate 10 as a whole; then the embedded column 20 is screwed, and a single embedded column 20 is separated from the side wall and the positioning mounting plate 10 in turn; at this time, the positioning mounting plate 10 on the side wall can be pried off, and the installation position of the embedded column 20 and the positioning mounting plate 10 on the side wall can be repaired.

[0054] The disassembled detachable assembled construction elevator support device is then transferred and installed and used at a new construction site, so that the detachable assembled construction elevator support device can be reused as a whole, thereby reducing construction costs.

[0055] Example 2

[0056] The difference between Example 2 and Example 1 is basically as shown in the attached Figure 4 As shown, the longitudinal section profile of the groove 401 is in a “convex” shape, and the longitudinal section profile of the extension plate 403 is also in a “convex” shape that is embedded and abutted against the groove 401 of the horizontal support column 40 .

[0057] like Figure 4 As shown, a rack 405 is integrally formed on the side of the extension plate 403; a mounting cavity 701 is provided in the end of the horizontal support column 40 away from the side wall, and a gear 702 meshing with the rack 405 is rotatably installed in the mounting cavity 701 of the horizontal support column 40, and a dial wheel 703 is rotatably installed on the lower surface of the horizontal support column 40, and the dial wheel 703 passes through the horizontal support column 40 and is coaxially welded to the gear 702.

[0058] When adjusting the extension plate 403 in the detachable assembled construction elevator support device in this embodiment, the holding dial 703 is rotated forward or reversely. When the dial 703 is rotated forward, the dial 703 drives the gear 702 to rotate forward synchronously, and the gear 702 engages with the rack 405, thereby driving the extension plate 403 to extend horizontally along the groove 401 to the outside of the groove 401, thereby expanding the support range of the detachable assembled construction elevator support device for the construction elevator and improving the comprehensiveness of the support for the construction elevator; when the extension plate 403 is supporting the construction elevator, the side edge of the extension plate 403 is stably abutted against the side wall of the groove 401 of the horizontal support column 40, so that the support of the extension plate 403 is stable, and at the same time, the groove 401 can guide the horizontal movement of the extension plate 403.

[0059] When the thumbwheel 703 rotates in the reverse direction, the thumbwheel 703 drives the gear 702 to rotate in the reverse direction synchronously, thereby driving the extension plate 403 to be folded horizontally along the groove 401 into the groove 401 , so that the folding control of the extension plate 403 is convenient.

[0060] On the whole, the extension and retraction of the extension plate 403 and the guidance during the extension and retraction are more convenient and stable, and the operation is more labor-saving.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
