Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a bearing frame for building construction. Background Art

[0002] Construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into physical objects at designated locations. In the process of construction, load-bearing frames are needed. Traditional load-bearing frames include load-bearing frame bodies, bases, casters, top frames, uprights, baffles and standing boards, etc., which are used to carry workers to higher locations for construction work.

[0003] However, the current support frame structure still has certain problems during use: First, the top of the support frame is high, and when workers are working on it, the bottom support is easily unstable, so some support frames will be equipped with a structure to stabilize the support. However, the construction site is sometimes bumpy, and the current support structure cannot adapt to this terrain, and the support components cannot be folded, which takes up a lot of space. Secondly, the platform space on the top of the support frame is limited. Sometimes there are parts on both sides of the support frame that need to be constructed, and workers have to readjust the position of the device or lean out of the fence to operate, which has certain shortcomings.

[0004] Therefore, it is necessary to provide a new bearing frame for building construction to solve the above technical problems. Summary of the invention

[0005] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the utility model is to provide a construction load-bearing frame having a stable support assembly that can adapt to various terrains and a foldable and extendable top load-bearing platform.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A load-bearing frame for construction, wherein vertical poles are vertically arranged at the four corners of the upper end of the base, a limiting sleeve is provided on the sliding sleeve of the vertical pole, a first cantilever is rotatably connected to the outer surface of the limiting sleeve, a fixing plate is provided between the limiting sleeve and the first cantilever, a plurality of limiting holes evenly distributed around the axis are opened on the surface of the fixing plate, limiting nails are inserted into the limiting holes, and the bottom ends of the limiting nails protrude into the first cantilever;

[0008] One end of the first cantilever away from the limiting sleeve is slidably connected to the second cantilever, one end of the second cantilever away from the first cantilever is fixed with a supporting outer rod arranged parallel to the vertical rod, and the bottom end of the supporting outer rod is slidably connected to the supporting inner rod.

[0009] Furthermore, a support platform is provided between the tops of the four uprights, and a double-headed screw is rotatably connected inside the support platform via a connecting block.

[0010] Furthermore, both side ends of the double-headed screw are threadedly connected to side platforms, both side platforms are slidably connected to the supporting platform, and one end of the side platform is located outside the supporting platform.

[0011] Furthermore, a first bevel gear is fixedly provided on the double-headed screw between the two side platforms, and a second bevel gear is meshed at the bottom of the first bevel gear.

[0012] Furthermore, the second bevel gear is arranged outside the supporting platform, a driving motor is installed at the bottom of the second bevel gear, the driving motor is fixedly connected to the bottom of the supporting platform through a connecting plate, and an output end of the driving motor is connected to the second bevel gear.

[0013] Furthermore, an oblique support frame is arranged between two groups of vertical poles located at the same side end of the base.

[0014] Furthermore, both the front and rear sides of the support platform are fixedly connected with protective outer rods through connecting pieces, and both ends of the protective outer rods are slidably connected with protective inner rods.

[0015] Furthermore, protective plates are provided at both left and right ends of the support platform, and one end of the protective inner rod away from the protective outer rod is connected to the protective plate adjacent to it.

[0016] Furthermore, a mounting plate is provided on the outer side of the protective outer rod, a ladder is provided on the outer side of the mounting plate, and both ends of the mounting plate and the ladder are respectively connected to the protective outer rod and the base.

[0017] Furthermore, the bottom of the supporting inner rod is threadedly connected with a supporting foot, and universal wheels are arranged at the four corners of the bottom of the base.

[0018] Furthermore, a threaded sleeve is fixedly connected between the four limit sleeves via a connecting plate, a side wall of the mounting plate close to the base is fixedly connected to a side plate, the side plate is rotatably connected to a threaded rod, the threaded rod and the threaded sleeve are threadedly connected, and a turntable is arranged on the top of the threaded rod.

[0019] Furthermore, a plug is inserted into the surface of the supporting outer rod, and a plurality of evenly arranged plug holes are longitudinally distributed on the surface of the supporting inner rod, and one end of the plug protrudes into the inside of the plug hole.

[0020] The beneficial effects of the utility model are:

[0021] (1) The support assembly of the load-bearing frame can be stored on the upper side of the base by rotating when not in use, and does not take up much space. When it is needed, the angles of the four first cantilevers are adjusted and fixed at the angles by using limit pins and fixing plates. Because there are some potholes on the ground when working on a construction site, in order to enable the four supporting feet to be inserted into the ground to provide stable support for the structure, the user can adjust the position of the supporting inner rod according to the actual situation and fix it with a latch. After that, the turntable can be rotated to allow the threaded sleeve threadedly connected to the threaded rod to bring the four groups of support assemblies down until the supporting feet at the bottom are fully in contact with the ground. This structural design can adapt to various types of ground, ensuring that the load-bearing frame has stable bottom support during use;

[0022] (2) The space at the top of the traditional support frame is fixed and cannot be extended. When the operator needs to construct the building surface on both sides of the support platform, he can only readjust the position of the structure or lean out of the guardrail. This is inconvenient and poses a great safety hazard to operation. In the support frame described in the utility model, corresponding side platforms are added to the two sides of the support platform, which increases the working space at the top. When the operator needs to use it, he can turn on the drive motor. The drive motor drives the second bevel gear to rotate at its output end. The second bevel gear will transfer kinetic energy to the first bevel gear meshing with it. The first bevel gear drives the double-headed screw to rotate, thereby allowing the side platform to extend out of the support platform. When the operation is completed, the two side platforms can be retracted into the support platform, which is convenient for storage and does not take up much storage space.

[0028] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments and drawings. The contents mentioned in the implementation modes are not intended to limit the present invention.

[0029] Example 1

[0030] like Figure 1-4 As shown, this embodiment provides a bearing frame for construction, including a base 1, wherein four corners of the upper end of the base 1 are vertically provided with upright poles 3, a limiting sleeve 12 is slidably sleeved on the upright pole 3, a first cantilever 19 is rotatably connected to the outer surface of the limiting sleeve 12, a fixing plate 17 is provided between the limiting sleeve 12 and the first cantilever 19, a plurality of limiting holes evenly distributed around the axis are opened on the surface of the fixing plate 17, limiting nails are inserted into the limiting holes, and the bottom ends of the limiting nails protrude into the first cantilever 19;

[0031] The end of the first cantilever 19 away from the limiting sleeve 12 is slidably connected to the second cantilever 20 , and the end of the second cantilever 20 away from the first cantilever 19 is fixed with a supporting outer rod 15 arranged parallel to the vertical rod 3 , and the bottom end of the supporting outer rod 15 is slidably connected to the supporting inner rod 16 .

[0032] Furthermore, a support platform 2 is provided between the tops of the four uprights 3, and a double-headed screw 24 is rotatably connected to the interior of the support platform 2 via a connecting block.

[0033] Furthermore, both side ends of the double-headed screw 24 are threadedly connected to side platforms 8 , both side platforms 8 are slidably connected to the support platform 2 , and one end of the side platform 8 is located outside the support platform 2 .

[0034] Furthermore, a first bevel gear 25 is fixedly disposed on the double-headed screw 24 between the two side platforms 8 , and a second bevel gear 26 is meshed at the bottom of the first bevel gear 25 .

[0035] Furthermore, the second bevel gear 26 is arranged outside the supporting platform 2 , and a driving motor is installed at the bottom of the second bevel gear 26 . The driving motor is fixedly connected to the bottom of the supporting platform 2 via a connecting plate, and the output end of the driving motor is connected to the second bevel gear 26 .

[0036] Through the above technical solution, the space at the top of the traditional load-bearing frame is fixed and cannot be extended. When workers need to construct the building surface at the two sides of the support platform 2, they can only readjust the position of the structure or lean out of the guardrail, which is inconvenient and has a greater operational safety hazard. In the utility model, by adding corresponding side platforms 8 at the two sides of the inside of the support platform 2, the top working space is increased. When workers need to use it, they can turn on the drive motor. The drive motor drives the second bevel gear 26 to rotate from its output end. The second bevel gear 26 will transfer kinetic energy to the first bevel gear 25 meshing with it. The first bevel gear 25 drives the double-headed screw 24 to rotate, thereby allowing the two side platforms 8 to extend out of the inside of the support platform 2. When the operation is completed, the two side platforms 8 can be retracted into the inside of the support platform 2, which is convenient for storage and does not take up much storage space.

[0037] Furthermore, an oblique support frame 4 is provided between the two groups of upright poles 3 located at the same side end of the base 1 .

[0038] Furthermore, both the front and rear sides of the support platform 2 are fixedly connected with protective outer rods 27 through connecting pieces, and both ends of the protective outer rods 27 are slidably connected with protective inner rods 9.

[0039] Furthermore, protective plates 10 are provided at both left and right ends of the support platform 2 , and one end of the protective inner rod 9 away from the protective outer rod 27 is connected to the protective plate 10 adjacent thereto.

[0040] Through the above technical solution, when the side platform 8 is extended from the inside of the supporting platform 2, the protective inner rod 9 will also extend from the inside of the protective outer rod 27, thereby providing safety protection for the workers working thereon.

[0041] Furthermore, a mounting plate 5 is provided on the outer side of the protective outer rod 27 , and a ladder 6 is provided on the outer side of the mounting plate 5 . Both ends of the mounting plate 5 and the ladder 6 are connected to the protective outer rod 27 and the base 1 , respectively.

[0042] Through the above technical solution, when the operator needs to work on the top support platform 2, he can first install the stable support components on the four vertical poles 3, and then reach the support platform 2 through the ladder 6 to work. This can ensure that when the workers go up and down the support platform 2, the structure of the carrier is stable enough and will not shake, thereby ensuring the operator's work safety.

[0043] Furthermore, the bottom of the supporting inner rod 16 is threadedly connected with a supporting foot 18, and the four corners of the bottom of the base 1 are provided with universal wheels 23. The universal wheels 23 can facilitate the operator to push the carrier to move, and the supporting feet 18 on the supporting inner rod 16 can allow the carrier to achieve stable support at a certain place.

[0044] Furthermore, a threaded sleeve 11 is fixedly connected between the four limit sleeves 12 via a connecting plate, a side wall of the mounting plate 5 close to the base 1 is fixedly connected to a side plate 7, the side plate 7 is rotatably connected to a threaded rod 13, the threaded rod 13 is threadedly connected to the threaded sleeve 11, and a turntable 14 is provided on the top of the threaded rod 13.

[0045] In the utility model, the support assembly (i.e., the limit sleeve 12, the first cantilever 19, the second cantilever 20, the support outer rod 15 and the support inner rod 16 and other structures) can be stored above the base 1 by rotation when not in use, and does not take up much space. When it is needed, the angles of the four first cantilevers 19 are adjusted and fixed at the angle using the limit nails and the fixing plate 17. When working on a construction site, there are some potholes on the ground. In order to enable the four support legs 18 to be inserted into the ground to provide stable support for the structure, the operator can adjust the position of the support inner rod 16 according to actual conditions and fix it using the latch 21. After that, the turntable 14 can be rotated to allow the threaded sleeve 11 threadedly connected to the threaded rod 13 to descend with the four groups of support assemblies until the support legs 18 at the bottom are in full contact with the ground. This structural design can adapt to various types of ground to ensure that the load-bearing frame has stable bottom support during use.

[0046] Furthermore, a pin 21 is inserted on the surface of the outer support rod 15, and a plurality of evenly arranged insertion holes 22 are longitudinally distributed on the surface of the inner support rod 16, and one end of the pin 21 protrudes into the insertion hole 22. Since the ground of some construction sites is bumpy, in order to allow all four support legs 18 to be supported on the ground, through the cooperation of the pin 21 and the insertion hole 22, the operator can flexibly adjust the extension length of each inner support rod 16 to adapt to the actual situation.

[0047] The working principle of a construction support frame provided by the utility model is as follows:

[0048] First, the support assembly of the carrier frame can be stored on the upper side of the base 1 by rotating when not in use, so as not to occupy much space. When it is needed, the angles of the four first cantilevers 19 are adjusted and fixed at the angles by means of limit nails and fixing plates 17. Because there are some potholes on the ground when working on a construction site, in order to enable the four supporting feet 18 to be inserted into the ground to provide stable support for the structure, the user can adjust the position of the supporting inner rod 16 according to the actual situation and fix it with the latch 21, and then the turntable 14 can be rotated to allow the threaded sleeve 11 threadedly connected to the threaded rod 13 to descend with the four groups of support assemblies until the supporting feet 18 at the bottom thereof are in full contact with the ground. This structural design can adapt to various types of ground, ensuring that the carrier frame has stable bottom support during use;

[0049] Second, the space at the top of the traditional support frame is fixed and cannot be extended. When the operator needs to construct the building surface at the two sides of the support platform 2, he can only readjust the position of the structure or lean out of the guardrail. This is inconvenient and has a great hidden danger of operation safety. In the support frame described in the utility model, the corresponding side platforms 8 are added to the two sides of the support platform 2, which increases the working space at the top. When the operator needs to use it, he can turn on the drive motor. The drive motor drives the second bevel gear 26 to rotate from its output end. The second bevel gear 26 will transfer kinetic energy to the first bevel gear 25 meshing with it. The first bevel gear 25 drives the double-headed screw 24 to rotate, thereby allowing the side platforms 8 to extend out of the inside of the support platform 2. When the operation is completed, the two side platforms 8 can be retracted into the inside of the support platform 2, which is convenient for storage and does not take up much storage space.

[0050] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present invention is within the protection scope of the present invention.
