Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically to a construction scaffolding that is easy to assemble quickly. Background Technology

[0002] Scaffolding refers to various supports erected on construction sites to facilitate worker operations and vertical and horizontal transportation. It is a common term in the construction industry, referring to the various supports erected on construction sites for exterior walls, interior decoration, or high-ceilinged areas where direct construction is not possible. It is mainly used for construction workers to move up and down, for external safety netting, and for the installation of components at height. Simply put, it is setting up a frame. Scaffolding materials usually include bamboo, wood, steel pipes, or composite materials. In some projects, scaffolding is also used as formwork. In addition, it is widely used in advertising, municipal, transportation, road and bridge, and mining industries.

[0003] The current announcement number: CN 217400306 U describes a type of scaffolding for easy construction, in which the installation pipe is fixedly installed inside the connector; the fixing plate is fixedly installed in the middle of the inner side of the installation pipe, and vertical rods are respectively installed on the upper and lower sides of the fixing plate, with the inner ends of the vertical rods passing through the connector; fixing sleeves are respectively fixedly installed on the vertical rods, and the left and right sides of the fixing sleeves are respectively screwed to the connector using fixing bolts; working blocks are respectively fixedly installed on the left and right sides of the installation pipe; horizontal rods are respectively inserted on the left and right sides of the connector; installation blocks are respectively fixedly installed on the inner ends of the horizontal rods, and each installation block has an installation groove; compression springs are respectively fixedly installed inside the installation grooves; and movable plates are respectively... The device is fixedly installed at the outer end of the compression spring; the limiting blocks are respectively fixedly installed on the outer side of the moving plate, and the limiting blocks are respectively movably installed in the limiting groove; it is convenient to install and disassemble each bracket, convenient to store and transport, and more practical. However, during the use of this device, it was found that the connecting parts of the device are too complicated and there are electrical equipment such as motors, which makes it inconvenient to quickly assemble and disassemble, reducing the efficiency of scaffolding. At the same time, the horizontal bar contains components such as mounting blocks and springs, which leads to a lot of material consumption for replacing the horizontal bar, increasing the cost of replacing the horizontal bar and making it unfavorable for subsequent replacement and use. Therefore, we propose a construction scaffolding that is easy to assemble quickly. Utility Model Content

The bottom front left side and the bottom rear left side of the mounting housing on the left side are fixedly connected to the bottom front right side and the bottom rear right side of the mounting housing on the right side. The first positioning rod is inserted into the inner cavity of the first positioning groove. The left side of the front and rear side walls of the mounting housing on the right side is fixedly connected to a retaining sleeve. The bottom center of the inner side wall of the groove has a threaded groove. The top right center of the outer side wall of the crossbar on the left side and the top left center of the outer side wall of the crossbar on the right side have a second through hole. The right side of the outer side wall of the crossbar on the left side and the left side of the outer side wall of the crossbar on the right side are fitted with a sleeve plate.

[0006] As a further description of the above technical solution:

[0007] The second positioning sleeve has a mounting groove in the middle of the right side of its bottom, and a movable rod is slidably connected to the inner cavity of the mounting groove.

[0008] As a further description of the above technical solution:

[0009] The bottom end of the movable rod is fixedly connected to a pressure plate, and the pressure plate is slidably connected to the outer wall of the upright.

[0010] As a further description of the above technical solution:

[0011] The second positioning sleeve has a threaded hole in the middle of the top left side, and a threaded rod is threadedly connected to the inner cavity of the threaded hole, and the threaded rod is rotatably connected to the middle of the top left side of the pressure plate.

[0012] As a further description of the above technical solution:

[0013] A first positioning bolt passes through the inner cavity of the first through hole and the inner cavity of the second through hole, and the first positioning bolt is threadedly connected to the inner cavity of the threaded groove.

[0014] As a further description of the above technical solution:

[0015] A retaining plate is fixedly connected to the right side of the front and rear side walls of the mounting sleeve on the left side, and the retaining plate is located in the inner cavity of the sleeve. A second positioning bolt is threaded between the upper and lower sides of the left side wall of the retaining plate and the upper and lower sides of the right side wall of the inner cavity of the sleeve.

[0016] As a further description of the above technical solution:

[0017] The inner sidewall of the sleeve is fixedly connected to the middle of the upper and lower sides, and the second positioning rod is inserted into the inner cavity of the second positioning groove.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This scaffolding, which facilitates rapid assembly, uses a method where horizontal bars are inserted into second positioning slots via second positioning rods. First positioning bolts, passing through first and second through holes, are threaded into threaded slots, causing the horizontal bars to be fixed to the mounting sleeves as a single unit. Then, by inserting the first positioning rods sequentially into the first positioning slots, a clamping plate is driven into the clamping sleeve and secured by the second positioning bolts. Next, rotating the knob on the threaded rod pushes the pressure plate against the top of the two mounting sleeves, completing the assembly. Rotating the knob on the threaded rod moves the pressure plate upwards. Disassembly is completed by directly removing the second positioning bolts, first lifting the right horizontal bar upwards, then lifting the left horizontal bar upwards, causing the first positioning rods to disengage from the first positioning slots. This method facilitates rapid assembly and disassembly of the scaffolding, improving its efficiency.

[0020] 2. This construction scaffold, which is easy to assemble quickly, can be replaced by removing the first positioning bolt, which drives the first positioning bolt out of the first through hole and the second through hole and the threaded groove. Then, the horizontal bar can be pulled out from the groove in the mounting sleeve for replacement. This process only requires replacing a single horizontal bar and the positioning assembly consisting of its sleeve plate and the second positioning rod, which reduces the material consumption for replacing the horizontal bar, thereby reducing the cost of replacing the horizontal bar and facilitating subsequent replacement and use.
