Description

Technical Field

[0001] The utility model relates to the technical field of building construction assistance, in particular to a scaffold that can be spliced ​​during the building construction stage. Background Art

[0002] Scaffolding is a working platform set up to ensure the smooth progress of each construction process. It refers to various supports set up at the construction site for workers to operate and solve vertical and horizontal transportation. It is often used in places on construction sites where the exterior wall height is high and direct construction is not possible. During the construction process, it is necessary to carry out bricklaying, mesh hanging and painting on the walls of the building. During the process of bricklaying, mesh hanging and painting at high places on the wall, human hands cannot directly reach the construction area, so the help of scaffolding is needed. Construction workers stand on the scaffolding to complete the construction work at high places.

[0003] Among them, the splicable scaffolding for construction disclosed in application number CN201821977702.5 is also an increasingly mature technology. The use of double pull rods can make the connecting legs directly pulled more firmly and tightly. The use of threaded rods for tightening can prevent the pull rods from automatically extending when the pulling force is too large, making the fixing effect unstable. The handle design will not hurt the hand when turning the threaded rod, making the rotation smoother. The fixed frame is firmly fixed by a fixed block, which can prevent the fixed block from failing under the action of the threaded rod and causing work accidents.

[0004] A scaffolding with easy height adjustment disclosed in CN202223365084.8 is also an increasingly mature technology. The opening angle of the legs is adjusted by the retraction mechanism between the legs so that the legs remain in an outwardly opened state. At this time, the overall structure is more stable. At the same time, the legs can also be retracted inward, which is convenient for the overall retraction and carrying of the scaffolding. When the length of the legs needs to be adjusted to adapt to uneven ground, the telescopic mechanism is adjusted to extend the foot pad from the bottom of the leg, and the length of the leg is preliminarily adjusted. Then, the threaded rod is rotated to punch the threaded rod out of the telescopic mechanism. At this time, the length of the leg is adjusted in detail to make the height adjustment of the leg more accurate. At the same time, the ball head can be rotated at an appropriate angle in the foot pad to ensure that the foot pad can remain horizontal in real time, and the scaffolding has a wider range of uses.

[0005] Based on this, we agree with the advantages of the above products, but there are still the following defects:

[0006] When the scaffold is used for construction at a relatively high position, the existing scaffold is not convenient for adjusting the height, resulting in the inability to adjust the scaffold according to the required construction height, which brings inconvenience to the construction workers;

[0007] When the scaffold is in use, it is not convenient for construction workers to climb up and it lacks safety. Utility Model Content

[0008] The utility model aims to provide a scaffold that can be spliced ​​during the construction phase of a building, so as to solve the problems in the background art that the scaffold cannot be adjusted according to the required construction height and the construction workers are inconvenient and lack safety.

[0009] The embodiment of the utility model provides a scaffold that can be spliced ​​during the construction phase of a building, including a lifting mechanism;

[0010] Wherein, the lifting mechanism includes a forward and reverse screw rod, both ends of the forward and reverse screw rod are equipped with mounting sleeves and bearing sleeves are arranged inside, the bearing sleeves are located outside the two ends of the forward and reverse screw rods, and sliding blocks are slidably threaded on the surface of the forward and reverse screw rods, and the bottoms of the two sliding blocks are equipped with upper mounting seats, the bottoms of the upper mounting seats are connected to support rods, and both ends of the support rods are connected to the upper mounting seats through pins and grooves are opened on both sides of the two ends, the two support rods are arranged in an X-shaped cross and a fixed shaft is installed at the connection, and the ends of the support rods away from the forward and reverse screw rods are connected to the lower mounting seat through pins and connected to a rectangular block at the bottom;

[0011] In this embodiment, the rotation of the forward and reverse screw rods drives the sliding blocks on the surface to move away from or towards each other. When they move closer to each other, the lifting plate is raised, and when they move away from each other, the lifting plate is lowered, thereby lifting and lowering the scaffolding. The bearing sleeve reduces the friction between the forward and reverse screw rods and the mounting sleeve. The two support rods are arranged in an X-shape and a fixed shaft is installed at the connection, which can make the support rods more firm and stable, increase the load-bearing capacity, and improve safety.

[0012] In an implementation manner of the utility model, a motor is installed at one end of the forward and reverse screw rods, and a fixed bearing is installed at one end of the forward and reverse screw rods away from the motor.

[0013] In this solution, the forward and reverse screw rods are started by the motor, and the fixed bearings can provide support for the forward and reverse screw rods to perform the functions of fixing and positioning.

[0014] In one embodiment of the utility model, a lifting plate is installed on the top of the mounting sleeve, lifting columns are installed on the four corners of the bottom of the lifting plate and a bottom plate is installed on the bottom, a rectangular groove is opened on the top of the bottom plate and a rectangular block is slidably installed inside, and fixable universal wheels are installed on the four corners of the bottom of the bottom plate.

[0015] In this solution, when the lifting mechanism is started, the lifting column is used to keep the lifting plate balanced on all sides. While the sliding block rotates on the positive and negative screw rod surfaces, the rectangular block slides synchronously along the rectangular groove. The universal wheel is used to facilitate construction workers to move the scaffolding to the required position, saving time and effort.

[0016] In an implementation manner of the utility model, a fence is installed on the top of the lifting plate, and a door body is installed on one side of the fence.

[0017] In this solution, the fence is used to protect the safety of construction workers at work and prevent people or objects from falling or sliding from the top. The door body facilitates the control of entry and exit inside the fence.

[0018] In an implementation manner of the utility model, the door body is rotatably installed through a sleeve on the side of the fence, and a latch is installed on the side of the door body away from the sleeve.

[0019] In this solution, the latch can be embedded in a fixed position when the door body is closed, ensuring that the door body will not be accidentally opened or closed during use, thereby increasing the safety of the scaffolding.

[0020] In one embodiment of the utility model, a climbing ladder is installed at the bottom of the lifting plate located at the latch, the top of the climbing ladder is fixedly connected to the bottom of the lifting plate through a convex plate, and one side of the convex plate is fixedly connected to the climbing ladder.

[0021] In this solution, when the lifting platform is raised to a high place, it is convenient for construction workers to crawl. The bottom of the lifting platform and one side of the climbing ladder are fixedly connected by a convex plate, so that the lifting platform and the climbing ladder are firmly connected, thereby increasing the structural strength of the scaffolding.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] 1. Since there is a sliding block on the surface of the positive and negative screw rods, the bottom of the sliding block is connected to one end of the support rod through the upper mounting seat, and the other end of the support rod is connected to the lower mounting seat at the top through the rectangular block. The two support rods are arranged in an X-shaped cross and a fixed shaft is installed at the connection. By starting the motor, the positive and negative screw rods are driven to rotate. The rotation of the positive and negative screw rods drives the sliding blocks on the surface to move away from or approach each other. When they move closer to each other, the lifting plate is raised, and when they move away from each other, the lifting plate is lowered. When the sliding block 112 rotates on the surface of the positive and negative screw rods, the rectangular block slides synchronously along the rectangular groove, thereby lifting and lowering the scaffolding;

[0024] 2. The construction worker crawls along the ladder. When crawling to the door body, he opens the latch on the door body with one hand, crawls to the top of the lifting plate, and embeds the latch into a fixed position when the door body is closed to ensure that the door body will not be accidentally opened during use. The fence protects the safety of construction workers at work and prevents people or objects from falling or sliding from the top. BRIEF DESCRIPTION OF THE DRAWINGS
