Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and in particular relates to a cantilevered disc-lock scaffold. Background Technology

[0002] Scaffolding is an indispensable temporary structural facility in construction projects. It is mainly used to provide construction workers with high-altitude working platforms, material storage and short-distance transportation support, while ensuring construction safety. There are various types of scaffolding. According to materials, it can be divided into bamboo and wood scaffolding, steel pipe scaffolding and aluminum alloy scaffolding. According to the structural form, it can be divided into single-row scaffolding, double-row scaffolding, full-span scaffolding, cantilevered type, attached lifting type, etc. Modern scaffolding is mainly based on steel pipes. Among them, coupler-type steel pipe scaffolding dominates in China due to its low cost and strong adaptability, while cup-lock scaffolding and frame scaffolding are gradually being used in bridges, large public buildings and other fields due to their efficient assembly and disassembly and strong load-bearing capacity.

[0003] Currently, the scaffolding used in construction suffers from insufficient stability in vertical connections. The vertical steel pipes of the scaffolding are usually connected at only one point, posing a safety hazard of vertical separation. Furthermore, the connection between the bottom steel pipe and the base plate of the current scaffolding is usually only achieved through a few sets of bolts, and this single connection point is the point of greatest load on the entire scaffolding. Such a simple connection method is effective in bearing load but cannot support the load of multi-story scaffolding with greater height. Therefore, it is necessary to provide a cantilevered disc-lock scaffolding to solve the above problems. Utility Model Content

[0004] The technical content of this utility model is to provide a cantilevered disc-lock scaffold.

[0005] To address the aforementioned problems, this utility model provides a cantilevered disc-lock scaffold, comprising an installation pipe, an extension pipe installed at the top of the installation pipe, connecting rings installed at both ends of the installation pipe and the extension pipe, connecting pipes installed at the top and bottom of the installation pipe, a connecting pipe installed at the top of the extension pipe, a support pipe installed at the bottom of the installation pipe, a connecting ring installed at the top of the support pipe, a base plate installed at the bottom of the support pipe, an insert rod installed at the top of the base plate, four sets of threaded pipes symmetrically installed at the four corners of the base plate, threaded rods installed in the threaded pipes, a connecting sleeve installed at the top of the base plate, the connecting sleeve being configured as a symmetrical left and right part structure, six sets of reinforcing blocks symmetrically installed on the connecting sleeve, a fixing plate installed in the middle of both the installation pipe and the extension pipe, four sets of insert blocks symmetrically installed on the sides of the fixing plate, four sets of horizontal pipes symmetrically installed in the middle of the sides of the installation pipe and the extension pipe, and connecting blocks installed at both ends of the horizontal pipes.

[0006] As a further solution of this utility model, the mounting pipe and the extension pipe have the same specifications. The mounting pipe, extension pipe, connecting pipe, support pipe and horizontal pipe are all made of steel pipe. The bottom inner side of the extension pipe is provided with a connecting groove that matches the connecting pipe. The connecting pipe at the top of the mounting pipe is inserted into the bottom of the extension pipe. Two sets of bolts are symmetrically installed at the lower end of the extension pipe. The bolts pass through the fixing holes opened on the lower side of the extension pipe and the fixing holes opened on the connecting pipe, thereby fixing the connecting pipe in the bottom connecting groove of the extension pipe.

[0007] As a further solution of this utility model, the connecting ring at the bottom of the extension tube and the connecting ring at the top of the mounting tube are fixedly connected by six sets of bolts, thereby increasing the connection stability between the mounting tube and the extension tube.

[0008] As a further solution of this utility model, a connecting groove adapted to the connecting pipe at the bottom of the mounting pipe is opened on the inner side of the top of the support tube. The connection method between the support tube and the mounting pipe is the same as the connection method between the mounting pipe and the extension tube. The diameter of the insertion rod installed on the top of the base plate is the same as the inner diameter of the support tube. The insertion rod is inserted into the bottom of the support tube. The inner diameter of the upper end of the connecting sleeve is the same as the diameter of the support tube. Three sets of bolts are symmetrically installed on the bottom of the left and right parts of the connecting sleeve. The bottom of the bolts is installed in the fixing hole at the top of the base plate. The lower end of the support tube is inside the connecting sleeve. A bolt is installed on the upper side of the connecting sleeve. The bolt passes through the connecting fixing hole opened on the connecting sleeve, the support tube and the insertion rod. A bolt is installed on the lower end of the support tube. The bolt passes through the fixing hole on the support tube and the insertion rod. Then, the insertion rod is stably installed on the lower inner end of the support tube by two sets of bolts.

[0009] As a further solution of this utility model, the reinforcing block is configured as a right-angled trapezoidal structure, the bottom of the reinforcing block is fixedly connected to the top of the lower end of the connecting sleeve, and the side of the reinforcing block is fixedly connected to the outer side of the upper end of the connecting sleeve. The strength of the connecting sleeve can be effectively increased by six sets of reinforcing blocks.

[0010] As a further solution of this utility model, the threaded tube is fixedly installed in the mounting holes at the four corners of the base plate. The bottom of the threaded tube is flush with the bottom of the base plate, the top of the threaded tube is higher than the top of the base plate, the top of the threaded rod is set as a hexagonal structure, and the inner side of the threaded tube and the outer side of the threaded rod are provided with matching threaded groove structures. By rotating the threaded rod, the threaded rod can be moved along the threaded tube.

[0011] As a further solution of this utility model, the inner diameter of the fixing plate is the same as the diameter of the mounting tube and the extension tube. The fixing plate is fixedly installed on the middle of the outer side of the mounting tube and the extension tube. The side of the connecting blocks installed at both ends of the horizontal tube is provided with slots that are compatible with the inserts on the side of the fixing plate. The inserts are fixedly installed in the slots by bolts, thereby realizing the fixed installation of the horizontal tube on the side of the fixing plate.

[0012] Compared with related technologies, the cantilevered disc-lock scaffolding provided by this utility model has the following beneficial effects:

[0013] 1. This utility model installs connecting rings at both ends of the installation pipe and the extension pipe. After the installation pipe and the extension pipe are vertically connected through the connecting pipe, the connecting rings on the two are fitted together. The two sets of connecting rings are fixedly connected by six sets of bolts, thereby increasing the connection stability of the installation pipe and the extension pipe. By increasing the number of extension pipes installed at the top of the extension pipe, vertical splicing of scaffolding can be achieved. Compared with the traditional vertical connection method of scaffolding, this device has two connections, namely connecting pipe and connecting ring, making the vertical connection point of the scaffolding more solid and safer.

[0014] 2. This utility model installs a plug rod on the top of the base plate. The diameter of the plug rod is the same as the inner diameter of the support pipe. The plug rod is fixed to the lower inner end of the support pipe by a fixing bolt. A connecting sleeve is installed on the top of the base plate by a fixing bolt. The lower end of the support pipe is fixed to the connecting sleeve by a fixing bolt. This makes the connection between the support pipe and the base plate very firm and stable. Compared with the connection between the bottom steel pipe and the base plate of traditional scaffolding, the connection point between the support pipe and the base plate of this device can withstand stronger forces, and thus can adapt to the installation needs of scaffolding of larger heights and scales.

[0015] 3. This utility model installs a fixing plate on the outer middle of the mounting pipe and extension pipe. Four sets of inserts are symmetrically installed on the outer side of the fixing plate. Connecting blocks are installed at both ends of the horizontal pipe. The side of the connecting block has a slot that matches the inserts on the side of the fixing plate. The inserts are fixedly installed in the slots by bolts, thereby realizing the fixed installation of the horizontal pipe on the side of the fixing plate. Compared with the traditional method of connecting the horizontal and vertical steel pipes of scaffolding with pins, the inserts of this device are completely inside the connecting blocks, making the connection more firm and stable and having greater load-bearing capacity.
