Description

Technical Field

[0001] The present application relates to the technical field of construction engineering, and specifically discloses a support device for construction engineering. Background Art

[0002] The support device plays a very important role in construction projects. It occupies a place in both technical activities and engineering construction. However, the existing support devices of construction projects still have certain structural defects;

[0003] The most common one is the scaffolding device, which is formed by installing several steel pipes through the base. First of all, it needs to be determined that this scaffolding device is very stable, because there are buckles between the steel pipes to connect the various components;

[0004] The current problems are: there are problems with the steel pipes and the supporting bases under the steel pipes. There are two common types of scaffolding devices: 1. A scaffolding device without a supporting base. This scaffolding device lacks rigidity and is prone to overall tilt, posing certain safety hazards; 2. A scaffolding device with a supporting base. It is more troublesome to adapt this scaffolding device with a supporting base to the steel pipe. That is, since it is a temporary scaffolding, the size of the steel pipe is uncertain, and it is not certain that a steel pipe that can be adapted to this scaffolding device with a supporting base can be found. Therefore, it is more troublesome to use. In view of this, the inventor proposes a supporting device for construction projects. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that the steel pipe and the support base cannot be matched when the traditional scaffolding support device is temporarily installed using the support base.

[0006] In order to achieve the above object, the present invention provides the following basic scheme:

[0007] A supporting device for construction engineering, comprising a base, a lower cavity connected to the base, an upper cavity detachably connected to the lower cavity, a steel pipe passing hole arranged on the upper cavity, a connecting hole arranged on the lower cavity, an elastic expansion member arranged inside the lower cavity for receiving the steel pipe, and a fixing assembly for fixing the elastic expansion member and the steel pipe;

[0008] The inner top of the upper cavity is provided with a plurality of connection fulcrums, and elastic ropes are installed on the connection fulcrums. A receiving ring is provided above the connecting hole, and the free ends of the elastic ropes are connected to the receiving ring, and the receiving ring can contact the elastic telescopic member.

[0009] The principles and effects of this basic solution are:

[0010] 1. Compared with the prior art, the present device has a simple structure and an ingenious design. The present device is a bottom supporting structure in a supporting device, has a wide range of practicality and value, can be applied to the insertion of most steel pipes, realizes the connection between the steel pipes and the present device, and then realizes a scaffolding device with a supporting base, which has a certain rigidity, safety and stability.

[0011] 2. Compared with the prior art, the present device overcomes the problem of slight shaking caused by the insertion structure of steel pipes of any size. This slight shaking problem is due to the fact that the traditional insertion structure of steel pipes of any size can only ensure that the steel pipes will not shake within a rough range, but due to size mismatch, the steel pipes still have the problem of slight shaking. The present device avoids the above problem and solves the problem that the steel pipes and the support base cannot be adapted to each other when the traditional scaffolding support device is temporarily installed using the support base.

[0012] 4. Compared with the prior art, this device utilizes the form of rotating and inserting the steel pipe to realize the winding of the elastic rope on the surface of the steel pipe. Therefore, for the steel pipe, it not only has an insertion action, but also has a taut elastic rope around the steel pipe, and the taut elastic rope is used to overcome the problem of slight shaking of the steel pipe.

[0013] 5. Compared with the prior art, the device utilizes the form of rotating and inserting the steel pipe, which gives priority to expanding the diameter of the steel pipe, and then continues to insert the expanded steel pipe. The action of continuing to insert the steel pipe is utilized to realize axial fixation of the elastic rope. Based on the fact that the elastic rope has achieved azimuthal fixation, coupled with the axial fixation of the elastic rope, the elastic rope is prevented from sliding up and down on the steel pipe, thereby achieving connection stability of the elastic rope.

[0014] Furthermore, the upper cavity is slidably connected to the lower cavity, and the outer walls of the upper cavity and the lower cavity are fixedly connected with mounting columns, and the mounting columns are provided with double buckles, one of which is buckled on the mounting column on the upper cavity, and the other of which is buckled on the mounting column on the lower cavity.

[0015] Furthermore, the steel pipe passing holes include circular holes, square holes and special-shaped holes, and the inner walls of the steel pipe passing holes are all smooth walls.

[0016] Furthermore, the elastic telescopic part includes a receiving plate arranged inside the lower cavity below the connecting hole, an elastic telescopic rod arranged inside the base and connected to the receiving plate at its free end, a circular groove having a shape matching that of the receiving ring is opened on the upper surface of the receiving plate, and the receiving ring is connected to the circular groove.

[0017] Furthermore, the fixing assembly includes elastic plates arranged on both sides of the receiving plate, mounting holes opened on both sides of the lower cavity, and a connecting rod installed based on the mounting holes, one end of the connecting rod is connected to the elastic plate, and the other end of the connecting rod is placed outside the mounting hole.

[0018] Furthermore, when the receiving plate moves downward due to the force of the steel pipe, the elastic plate is compressed and reset to move toward the center of the lower cavity, and the end of the connecting rod placed outside the mounting hole moves toward the center of the lower cavity. When the end of the connecting rod placed outside the mounting hole stops, a connecting nut is connected to the end of the connecting rod.

[0019] Furthermore, after the elastic plate is compressed and reset and moves toward the center of the lower cavity, the elastic plate contacts the outer surface of the steel pipe, and a connecting component is provided at the contact position where the elastic plate contacts the outer surface of the steel pipe.

[0020] Furthermore, the connection assembly includes a connection block and a plurality of latches arranged at the end of the connection block, and the latches are in contact with the elastic rope wound around the steel pipe.

[0021] Furthermore, the latching teeth are triangular latching teeth. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0029] The figure marks in the drawings of the specification include: upper cavity 1, smooth wall 2, steel pipe through hole 3, steel pipe 4, lower cavity 5, base 6, mounting column 7, mounting hole 8, connecting hole 9, receiving plate 10, circular groove 11, elastic rope 12, connecting fulcrum 13, connecting block 17, connecting nut 18, connecting rod 19, latching tooth 20, elastic plate 21.

[0030] Implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown:

[0031] A supporting device for construction engineering, comprising a base 6, a lower cavity 5 connected to the base 6, an upper cavity 1 detachably connected to the lower cavity 5, a steel pipe passing hole 3 arranged on the upper cavity 1, a connecting hole 9 arranged on the lower cavity 5, an elastic expansion member arranged inside the lower cavity 5 for receiving the steel pipe 4, and a fixing assembly for fixing the elastic expansion member and the steel pipe 4;

[0032] The inner top of the upper cavity 1 is provided with a plurality of connection fulcrums 13, and elastic ropes 12 are installed on the connection fulcrums 13. A receiving ring is provided above the connecting hole 9, and the free ends of the elastic ropes 12 are connected to the receiving ring, and the receiving ring can contact the elastic telescopic member.

[0033] Specifically: the upper cavity 1 is slidably connected to the lower cavity 5, and the outer walls of the upper cavity 1 and the lower cavity 5 are fixedly connected with mounting columns 7, and the mounting columns 7 are provided with double buckles, one of the double buckles is buckled on the mounting column 7 on the upper cavity 1, and the other double buckle is buckled on the mounting column 7 on the lower cavity 5.

[0034] It is convenient for assembling and disassembling the upper cavity 1 and the lower cavity 5. The base 6 and the lower cavity 5 are also detachably connected, which facilitates the replacement of the elastic telescopic parts and the fixing components inside the lower cavity 5.

[0035] Regarding the steel pipe through hole 3: the steel pipe through hole 3 includes a circular hole, a square hole and a special-shaped hole, and the inner wall of the steel pipe through hole 3 is a smooth wall 2.

[0036] In order to improve the application scope of the device, the steel pipe through hole 3 can be any common steel pipe through hole 3, so that the temporarily obtained steel pipe 4 can enter the steel pipe through hole 3;

[0037] When the steel pipe 4 is inserted, the first thing the steel pipe 4 contacts is the receiving ring. Since the steel pipe 4 in the device is inserted by manual rotation, and the receiving ring is immovable, when the steel pipe 4 is rotated and inserted, the elastic rope 12 starts to rotate and wrap around the outer periphery of the steel pipe 4, thereby wrapping around the outer periphery of the steel pipe 4.

[0038] As the steel pipe 4 is wound, the steel pipe 4 continues to be pushed downward, so that the steel pipe 4 begins to contact the elastic expansion member;

[0039] Regarding the elastic telescopic part: the elastic telescopic part includes a receiving plate 10 arranged inside the lower cavity 5 and below the connecting hole 9, and an elastic telescopic rod arranged inside the base 6 and connected to the receiving plate 10 at its free end, and a circular groove 11 having a shape matching that of a receiving ring is formed on the upper surface of the receiving plate 10, and the receiving ring is connected to the circular groove 11.

[0040] When the steel pipe 4 continues to be pushed downward, the receiving plate 10 moves downward, causing the elastic telescopic rod to be compressed. The fixing assembly includes elastic plates 21 arranged on both sides of the receiving plate 10, mounting holes 8 opened on both sides of the lower cavity 5, and connecting rods 19 installed based on the mounting holes 8, one end of the connecting rod 19 is connected to the elastic plate 21, and the other end of the connecting rod 19 is placed outside the mounting hole 8.

[0041] As the receiving plate 10 moves downward, the resistance of the elastic plates 21 on both sides of the receiving plate 10 disappears and begins to reset. Specifically: when the receiving plate 10 is moved downward by the force of the steel pipe 4, the elastic plates 21 are compressed and reset and move toward the center of the lower cavity 5. The end of the connecting rod 19 placed outside the mounting hole 8 moves toward the center of the lower cavity 5. When the end of the connecting rod 19 placed outside the mounting hole 8 stops, a connecting nut 18 is connected to the end of the connecting rod 19.

[0042] The connecting nut 18 fixes the position of the connecting rod 19. After the position of the connecting rod 19 is fixed, the elastic plate 21 is fixed and always contacts the surface of the steel pipe 4.

[0043] After the elastic plate 21 is compressed and reset and moves toward the center of the lower cavity 5, the elastic plate 21 contacts the outer surface of the steel pipe 4. A connecting component is provided at the contact position where the elastic plate 21 contacts the outer surface of the steel pipe 4. The connecting component includes a connecting block 17 and a plurality of latch teeth 20 arranged at the end of the connecting block 17. The latch teeth 20 are triangular latch teeth 20, and the latch teeth 20 contact the elastic rope 12 wrapped around the steel pipe 4.

[0044] Specific implementation process:

[0045] In the first step, the steel pipe 4 is inserted through the steel pipe hole 3 and contacts the receiving ring, and then the steel pipe 4 is manually driven to rotate and continue to be inserted downward, so that the elastic rope 12 is wound around the steel pipe 4;

[0046] In the second step, when the thickness of the elastic rope 12 wound around the steel pipe 4 gradually increases, the rotation is stopped, and the steel pipe 4 is manually driven to continue to be inserted downward. The thickness of the elastic rope 12 wound around the steel pipe 4 is manually sensed. Specifically, the steel pipe 4 is tried to continue to be inserted downward to see whether the obstruction caused by the connecting hole 9 can be felt. When the obstruction caused by the connecting hole 9 can be felt, the rotation is stopped;

[0047] In the third step, after the steel pipe 4 is further inserted downward, the receiving plate 10 moves downward, the elastic telescopic rod is compressed, the resistance of the elastic plates 21 on both sides of the receiving plate 10 disappears, and the receiving plate 10 begins to reset. The latch teeth 20 contact the elastic ropes 12 wrapped around the steel pipe 4, and the latch teeth 20 are stuck in the gaps between the elastic ropes 12 to prevent the elastic ropes 12 from sliding up and down.

[0048] Step 4: Use the connecting nut 18 to fix the connecting rod 19, clamp it to the connecting block 17, and use the clamping force to fix the steel pipe 4;

[0049] For the steel pipe 4, under the action of the connecting block 17, the position of the steel pipe 4 is fixed, and under the action of the elastic rope 12 and the latch 20, the movement of the steel pipe 4 in a small range is locked, and the steel pipe 4 cannot achieve a small range of movement. Based on the design of the latch 20, the steel pipe 4 cannot achieve a small range of movement up and down. From then on, the installation of the steel pipe 4 is completed. Finally, based on several steel pipes 4, the installation of the scaffolding can be completed.

[0050] The device solves the problem that the steel pipe 4 and the support base 6 cannot be matched when the support base 6 is used for temporary installation in the traditional scaffolding support device.

[0051] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
