Description

Scaffolding for construction Technical Field

[0001] The present invention relates to the technical field of construction equipment, and more particularly to a scaffold for building construction. Background Art

[0002] When working at height, construction workers need to use scaffolding to provide an operating platform, a place to store construction materials, and personnel safety protection during the operation. Scaffolding is widely used in construction in the advertising industry, municipal administration, transportation roads and bridges, mining, etc.

[0003] When building a house in the countryside, the scaffolding needs to be clamped on the soil foundation when constructing the upper part of the wall. The ground of the soil foundation is usually uneven. The existing scaffolding is not easy to install on the uneven foundation. The operating platform is inclined, which brings safety hazards to the construction workers. The scaffolding is prone to shaking after installation. Conventional practice is to lay stones or bricks at the bottom of the scaffolding. The stones or bricks have been shifted, causing the scaffolding to shake. When the construction workers climb or stand on the side of the operating platform, the scaffolding may overturn, posing a major safety hazard.

[0046] As shown in Figures 1 to 6, the present invention provides a scaffold for construction, which includes:

[0047] The base 2 is a square frame structure. The four corners of the base 2 are each provided with a first through hole 21 extending vertically therethrough. A sleeve 22 is provided in each first through hole 21 for coaxial rotation. The rotation of each sleeve 22 is driven by a rotation mechanism.

[0048] The mounting tube 3 is coaxially disposed within the sleeve 22, with the inner wall of the sleeve 22 being spirally connected to the outer wall of the mounting tube 3. Each mounting tube 3 is vertically slidably connected to the inner wall of the first through hole 21. The mounting tube 3 is provided with a plurality of second through holes 31 spaced apart along the circumferential direction, and a first movable block 311 is provided in each second through hole 31 for radial sliding movement along the mounting tube 3.

[0049] The scaffolding body includes a working platform 11 and four legs 12 arranged at the bottom of the working platform 11; the four legs 12 correspond one-to-one to the four mounting tubes 3, and the lower end of each leg 12 is inserted into the corresponding mounting tube 3; each leg 12 is provided with a plurality of third through holes 122 corresponding one-to-one to a plurality of first movable blocks 311, and one end of each first movable block 311 can slide along the radial direction of the mounting tube 3 through the corresponding third through hole 122 and extend into the leg 12.

[0050] In the above technical solution, the present invention provides a scaffold for building construction, which includes a base 2 of a square frame structure, which is formed by four strip-shaped horizontal rods integrally formed and surrounded. The four corners of the base 2 are provided with first through holes 21 that pass through in the vertical direction. A hollow sleeve 22 is coaxially rotatably sleeved in each first through hole 21. The rotation of the sleeve 22 relative to the base 2 around its own axis is driven by a rotating mechanism. A mounting tube 3 is coaxially provided in each sleeve 22. Each mounting tube 3 is spirally connected to the sleeve 22 (by screwing it in the mounting hole). The outer wall of the cylinder 3 and the inner wall of the sleeve 22 are provided with matching spiral patterns), and at the same time, the installation cylinder 3 is slidably connected with the inner wall of the first through hole 21 in the vertical direction, so that the rotation of the sleeve 22 around its own axis can drive the installation cylinder 3 to move in the vertical direction, thereby realizing the automation of the downward movement of the installation cylinder 3 and improving the installation efficiency of the base 2; the scaffolding body is of conventional structural design, including a working platform 11 and four legs 12 provided at the four corners of the bottom of the working platform 11. The size of the base 2 is adapted to the size of the scaffolding body, and the peripheral design of the working platform 11 is A guardrail is installed, and each leg 12 can be inserted into the corresponding mounting tube 3. When the leg 12 is inserted into place, the first movable block 311 on the mounting tube 3 corresponds to the third through hole 122 on the leg 12 in the radial direction. The first movable block 311 moves inward along the radial direction of the mounting tube 3 and can pass through the third through hole 122 to be inserted into the leg 12, thereby connecting the leg 12 to the mounting tube 3. The four legs 12 and the four mounting tubes 3 are temporarily fixedly connected through the cooperation of the first movable block 311 and the third through hole 122, thereby connecting the scaffolding body to the base. 2 connection, by inserting the lower end of the installation tube 3 into the soil layer of the foundation, adjusting the insertion depth of the four installation tubes 3, the base 2 is firmly and nearly horizontally installed on the foundation, and then the scaffolding body is inserted into the installation tube 3 through the support legs 12, so that the scaffolding body can be quickly installed. There is no need to adjust the level of the bulky and large scaffolding body, which greatly improves the installation efficiency of the scaffolding. When the base 2 is firmly installed, the scaffolding as a whole is also stable, and there will be no problems of scaffolding shaking or tipping, thereby improving the safety of construction operations;

[0051] The present invention provides a scaffold for building construction, which includes a scaffold body and a base 2 for fixing the scaffold body to the ground. The base 2 and the scaffold body are a detachable assembly structure. When installing the scaffold on an uneven foundation soil surface, the lightweight and compact base 2 can be first installed in place to ensure the stability of the installation of the base 2. Then, the four legs 12 of the scaffold body are respectively inserted into the installation tubes 3 at the four top corners of the base 2. The legs 12 are connected to the installation tubes 3 through the cooperation of the first movable block 311 and the third through hole 122, thereby realizing the rapid and stable installation of the scaffold body. When installing the base 2, the upper surface of the base 2 is adjusted to a near horizontal level, thereby ensuring the horizontality of the scaffold body after it is installed in place.

[0052] The scaffolding for building construction provided by the present invention can be applied to construction sites with uneven ground, and solves the technical defects of the existing scaffolding body that is difficult to install stably on uneven foundation soil surface and the scaffolding body has tilted during operation, thereby realizing fast and stable installation of the scaffolding and improving the safety during construction operations.

[0053] In another technical solution, the scaffold for construction is such that the bottom of the mounting tube 3 is a conical structure, and the bottom of the leg 12 is a conical structure adapted to the bottom of the mounting tube 3;

[0054] Each mounting tube 3 is provided with a plurality of through-hole groups spaced apart in the vertical direction, and each through-hole group corresponds to a fixing mechanism, and each through-hole group includes a plurality of fourth through-holes 32 spaced apart along the circumference of the mounting tube 3; each fixing mechanism includes a plurality of elastic pins corresponding one-to-one to the plurality of fourth through-holes 32, one end of each elastic pin is a wedge-shaped structure and is located inside the mounting tube 3, and the other end passes through the corresponding fourth through-hole 32 and can pass out of the mounting tube 3; the other end of each elastic pin is a conical structure.

[0055] In the above technical solution, the present invention further discloses the specific structure of the installation tube 3, and the bottom of the installation tube 3 is set to a conical structure, which can be inserted into the soil layer of the foundation more quickly and stably. The interior of the installation tube 3 is hollow, and the bottom of the support leg 12 is set to a conical structure adapted to the interior of the installation tube 3, so that the lower part of the support leg 12 and the installation fit better. A plurality of fixing mechanisms are further provided on the installation tube 3. The installation tube 3 is inserted into the soil layer and can be firmly inserted into the soil layer through a plurality of fixing structures, thereby improving the stability of the installation of the base 2 and thus improving the stability of the scaffolding installation. Each specific fixing mechanism includes a plurality of elastic pins. When the support leg 12 is not inserted into the installation tube 3, the elastic pins are retracted to the installation tube 3. The support legs 12 are inserted into the mounting tube 3 to reduce the resistance of the mounting tube 3 to downward movement during the installation of the base 2. When the base 2 is installed in place, the support legs 12 are inserted into the mounting tube 3. The top angle of the lower end of the support legs 12 pushes the elastic pin of each fixing mechanism toward the periphery. The other end of the conical structure of the elastic pin passes through the corresponding fourth through hole 32 to pass through the mounting tube 3 and is inserted into the soil layer. The downward movement force of the support legs 12 is used to push the elastic pin into the soil layer. The support legs 12 are inserted into the third through hole 122 through the first movable block 311 and are temporarily fixed to the mounting tube 3. Through clever design, the horizontal self-locking connection between the mounting tube 3 and the soil layer is achieved, which avoids unnecessary displacement of the mounting tube 3 during construction, and can further improve the stability of the scaffolding and the safety of construction operations. After the construction work is completed, when the scaffolding is dismantled, the first movable block 311 is moved radially outward along the mounting tube 3, the first movable block 311 is withdrawn from the support leg 12, the scaffolding body is lifted vertically upward, the support leg 12 is withdrawn from the mounting tube 3, and the elastic pin moves horizontally inward along the radial direction of the mounting tube 3 into the mounting tube 3 under the action of its own elastic force, and the base 2 is lifted vertically upward, thus completing the dismantling of the scaffolding.

[0056] In another technical solution, in the scaffolding for construction, each first movable block 311 is provided with a first spring 312, one end of the first spring 312 is connected to the inner wall of the second through hole 31, and the other end is connected to the other end of the first movable block 311; each first movable block 311 is made of metal iron; an electromagnet is provided inside each support leg 12, and a plurality of third through holes 122 are arranged around the outer periphery of the electromagnet.

[0057] In the above technical solution, a first spring 312 is sleeved on the first movable block 311. As shown in Figures 1 and 3, before the leg 12 is inserted into the mounting tube 3, the first spring 312 naturally extends, and the distance between one end of the first movable block 311 and the axis of the mounting tube 3 is greater than the radius of the lower portion of the leg 12. That is, the first movable block 311 does not interfere with the vertical downward insertion of the leg 12 into the mounting tube 3. As shown in Figures 2 and 4, after the lower portion of the leg 12 is inserted into the mounting tube 3, the second through hole 31 and the third through hole 122 are radially aligned. When the electromagnet is energized, the electromagnet generates a magnetic attraction on the metallic first movable block 311, causing the first movable block 311 to move radially inward, pass through the third through hole 122, and be magnetically attracted to the outside of the electromagnet, connecting the leg 12 to the mounting tube 3. The power supply for the electromagnet can be provided on the base 2 using existing technical means, and a power switch button is provided to control the power supply of the electromagnet by operating the switch button.

[0058] In another technical solution, in the scaffolding for construction, the sleeve 22 is rotatably arranged at the lower part of the first through hole 21; a pair of fixed blocks are symmetrically provided on both sides of the upper inner wall of the first through hole 21; and a slide groove is provided on the two side walls of the mounting tube 3 in the vertical direction, and each fixed block is slidably arranged in the slide groove. The present technical solution specifically discloses a specific installation method of the sleeve 22 and the mounting tube 3. Specifically, as shown in Figures 3 and 4, the sleeve 22 is rotated and sleeved on the lower part of the first through hole 21. Multiple fixing mechanisms on the mounting tube 3 are arranged below the first through hole 21. Slide grooves are provided on both side walls of the mounting tube 3 (the front and rear sides parallel to the screen in Figures 3 and 4, not shown) in the vertical direction. A pair of fixed blocks on both sides of the first through hole 21 are respectively arranged in one-to-one correspondence with the two slide grooves on the two mounting tubes 3. Under the cooperation of the fixed blocks and the slide grooves, the movement of the mounting tube 3 is limited to the vertical direction. The first movable block 311 is located on the left and right sides of the mounting tube 3. The multiple first movable blocks 311 on the mounting tube 3 are staggered circumferentially with the pair of fixed blocks to ensure that the pair of fixed blocks do not interfere with the first movable block 311 moving downward with the mounting tube 3.

[0059] In another technical solution, each rotating mechanism of the building construction scaffold comprises:

[0060] A first gear plate 51 is fixedly mounted on the outside of the corresponding sleeve 22;

[0061] A rotating shaft 52 is vertically rotatably mounted on the base 2; an end of the rotating shaft 52 is connected to an output shaft of a motor 54;

[0062] The second gear plate 53 is fixedly mounted on the rotating shaft 52 and meshes with the first gear plate 51 .

The driving motor 54 drives the rotating shaft 52 to rotate, thereby driving the second gear plate 53 to rotate, driving the first gear plate 51 to rotate, thereby driving the sleeve 22 to rotate around its own axis, thereby driving the mounting tube 3 to move in the vertical direction; preferably, a switch button of the motor 54 can be set on the base 2, and the switch button of the motor 54 is used to control the opening and closing of the motor 54.

[0064] In another technical solution, each elastic pin of the building construction scaffold comprises:

[0065] The second movable block 41 has a wedge-shaped structure at one end and is located inside the mounting tube 3. The other end passes through the fourth through hole 32 and can pass out of the mounting tube 3. One end of each of the second movable blocks 41 is formed into a conical structure that adapts to the bottom corner of the support leg 12. The other end of each second movable block 41 is also a conical structure.

After the support leg 12 is inserted into the mounting tube 3, the support leg 12 stretches the multiple second movable blocks 41 outward, pushing the second movable block 41 to move radially outward, and the other end of the second movable block 41 passes through the fourth through hole 32 to pass through the outside of the mounting tube 3 and insert into the soil layer. The second spring 42 is compressed. After the support leg 12 is removed from the mounting tube 3, the elastic force of the second spring 42 can automatically reset the second movable block 41 to the state shown in Figures 1 and 3.

[0068] In another technical solution, the second movable block 41 of the construction scaffold is a hollow cylindrical structure; the other end of the second movable block 41 is composed of a plurality of spring pieces along the circumferential direction, and one end of each spring piece is elastically hinged to the other end of the second movable block 41 via a torsion spring;

[0069] Each second movable block 41 is provided with a corresponding reinforcement component, and each reinforcement component includes:

[0070] The reinforcing cone 43 is coaxially slidably disposed within the second movable block 41. One end of the reinforcing cone 43 is connected to the inner wall of the second movable block 41 via a horizontally disposed third spring 44, and the other end extends toward the other end of the second movable block 41.

[0072] Two stoppers 46 are provided, one for each clamping block 45. One end of each stopper 46 is located inside the second movable block 41, and the other end passes through the second movable block 41 along the radial direction of the second movable block 41 and is slidably connected to the inner wall of the fourth through hole 32 along the axial direction of the second movable block 41;

[0076] In the above technical solution, the present invention sets the other end of the second movable block 41 as a conical structure that can be elastically opened and closed. Specifically, it is composed of a plurality of spring plates hinged to the circumference of the first part of the cylindrical structure of the second movable block 41 through a torsion spring. In the absence of external force, the other ends of the plurality of spring plates are closed to form the pointed end of the conical structure. When an external force is applied (the reinforcement cone 43 pushes radially outward), the other ends of the plurality of spring plates are stretched open. As shown in FIG6 , the other end of the second movable block 41 is opened to form an opening for the reinforcement cone 43 to pass through, and the torsion spring is stretched.

[0078] Initial state (before the support leg 12 is inserted into the mounting tube 3): as shown in Figures 3 and 5, the other end of the second movable block 41 is located in the fourth through hole 32, the stop block 46 is located in the middle of the fourth through hole 32, the reinforcing cone 43 is located inside the second movable block 41, and the multiple springs at the other end of the second movable block 41 are in a retracted state. At this time, the block 45 is inserted into the slot 431, and the third spring 44 is in a compressed energy storage state; as shown in Figures 4 and 6, the installation state (after the support leg 12 is inserted into the mounting tube 3): the support leg 12 pushes the second movable block 41 outward, and the second movable block 41 moves along Moving radially outward, the stop block 46 abuts against the side wall of the fourth through hole 32 and is displaced relative to the second movable block 41, driving the rope body 48 to move, thereby pulling the blocking block 45 out of the blocking groove 431, and the fourth spring 49 is compressed. Under the elastic force of the third spring 44, the reinforcement cone 43 is pushed radially outward. The reinforcement cone 43 opens the multiple spring pieces and passes through the opening formed by the other ends of the multiple spring pieces, extending to the outside of the second movable block 41, which can increase the depth of the elastic pin inserted into the soil layer in the horizontal direction, thereby improving the stability of the connection between the mounting cylinder 3, the base 2 and the soil layer.

[0079] In another technical solution, the scaffold for construction is provided with a level on the upper surface of one side of the base 2. The level of the base 2 can be adjusted by observing the level.
