technical field

The utility model relates to the technical field of construction engineering, in particular to a scaffold used in the construction process.

Background technique

Scaffolding is mainly used in the external walls of construction sites or places where direct construction is not possible due to high storey heights. It is convenient for workers to work up and down, maintain peripheral safety nets, install components at high altitudes, and solve vertical and horizontal transportation. For the working position with a low floor height, the vertical horizontal rod, the horizontal short rod and the vertical rod can be assembled into a scaffold for operation through the simple installation of the connecting piece; for the high-rise operation, especially in the high-rise building During the construction of the building, it is necessary to build scaffolding on the periphery of the building. The scaffolding is usually erected from the ground and has been erected to the position where the operation is required. Because scaffolding is directly related to the safety of workers, traditional scaffolding is not only cumbersome to install, but also has poor safety. Therefore, developing a high-altitude scaffolding that is easy to install and has high safety performance has become one of the problems to be solved in the field of construction engineering.

The vertical horizontal rods, horizontal short rods and vertical rods are connected by connectors. One end of the shaped steel cantilever beam is installed on the concrete floor of a high-rise building through an anchor, and the other end of the shaped steel cantilever beam extends out of the high-rise building and is fixedly connected to the vertical pole of the main body of the scaffold.

The improvement of the utility model is that: the anchor includes a base plate, a pressing plate and at least two support rods vertically arranged on the base plate; the base plate is located below the concrete floor; The top end protrudes above the concrete floor; the pressure plate is sleeved on the upper part of the support rod; the steel cantilever beam penetrates into the space formed by the pressure plate, the concrete floor and the support rod, and is threaded on the fastening nut on the top of the support rod to press tight.

The further improvement of the utility model is that: the middle and lower parts of the support rods are sleeved with sleeves.

The improvement of the utility model also lies in that the cantilever beam of the shaped steel is an I-shaped steel, and the outer end of the I-shaped steel is provided with a through hole for fixing the main pole of the scaffold.

Due to the adoption of the above technical solutions, the technical progress achieved by the utility model is as follows.

The utility model securely installs the main body of the scaffold on the outside of the high-rise building through the section steel cantilever beam, which facilitates the installation on the basis of fully ensuring the safety of the operation; Scaffolding is enough, no need to build from the ground, which greatly reduces the construction difficulty and assembly cost. The anchor piece of the utility model can not only fix the steel cantilever beam conveniently, but also can be easily dismantled after the construction is finished, so as to be reused, which is beneficial to improve the construction efficiency and reduce the construction cost, and has good economy and practicality. sex.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The structure of the present utility model is shown in Figure 1 and Figure 2, comprises scaffold main body and section steel cantilever beam 1. The steel cantilever beam is used to support the main body of the scaffold on the outside of the high-rise building. One end of the steel cantilever beam 1 is installed on the concrete floor 2 of the high-rise building through the anchor 3, and the other end of the steel cantilever beam extends out of the high-rise building. And fixedly connect the main body of the scaffold.

The main body of the scaffold is composed of several longitudinal horizontal rods 4, horizontal short rods 6 and vertical rods 5, and the longitudinal horizontal rods, horizontal short rods and vertical rods are connected by connectors. The vertical rod of the main body of the scaffold is fixed in the through hole at the outer end of the section steel cantilever beam.

The structure of the anchor 3 is shown in FIG. 3 , including a bottom plate 32 , a pressing plate 34 and at least two support rods 31 vertically arranged on the bottom plate. Wherein the bottom plate 32 is located below the concrete floor 2; the bottom end of the support rod 31 is plug-welded on the bottom plate 32, and the top of the support rod 31 stretches out above the concrete floor, and is provided with an external thread, and is equipped with a fastening nut 33; a pressing plate 34 Sleeved on the upper part of the support rod 31. The height of the support bar is the thickness of the concrete floor and the height of the steel cantilever beam plus 150mm.

The shaped steel cantilever beam 1 penetrates into the space formed by the pressure plate, the concrete floor and the support rods, and the fastening nut 33 is screwed to compress the shaped steel cantilever beam under the action of the pressure plate. In this embodiment, there are two support rods, of course, it can also be set to 4, 6, 8..., all the support rods are arranged side by side in two rows, and the steel cantilever beams are located between the two rows of support rods, so as to Improve firm performance.

In the utility model, the anchor piece does not use the conventional U-shaped steel bar pull ring, which overcomes the occurrence of the position deviation of the U-shaped steel bar pull ring caused by the workers stepping on the roof steel bar when pouring concrete, and ensures the pre-embedded height of the anchor piece and The pre-embedded position makes the gap size between the steel cantilever beam and the anchor piece uniform, which is convenient for fixed installation.

In this embodiment, the steel cantilever beam is made of I-shaped steel, and the outer end of the I-shaped steel is provided with a through hole for fixing the main body of the scaffold. The bottom plate of the anchor is made of 220mm×100mm×8mm steel plate, the pressure plate is made of 10mm thick backing plate, the supporting rod is made of round steel with a diameter of Φ20mm, and the two round steel with a diameter of Φ20mm are connected with the steel plate of 220mm×100mm×8mm by plug welding. Flat, no protruding steel plate phenomenon. In the utility model, for the convenience of dismantling of the anchor piece, the middle and lower part of the support rod is covered with a sleeve 35, and the sleeve adopts a PVC sleeve with a diameter of Φ25mm.

The installation process of this embodiment is as follows:

First, pre-embed and fix the bottom plate on the concrete formwork, and the bottom surface of the bottom plate is tightly attached to the formwork, then put a Φ25mm diameter PVC casing on the Φ20mm round steel, and stick it tightly with adhesive tape to prevent mortar from entering the casing.

Then pour the concrete, and install the steel cantilever beam after the concrete is finally set.

When installing the shaped steel cantilever beam, place the shaped steel cantilever beam between two diameter Φ20mm round steels, after adjusting the position, put a 10mm thick backing plate on the diameter Φ20mm round steel, and place two on each diameter Φ20mm round steel Tighten the nut, tighten the nut to fasten, and the inner end of the section steel cantilever beam can be fixed.

Finally, the vertical rod 5 is installed on the outer end of the section steel cantilever beam, and then the vertical horizontal rod 4 and the transverse short rod 6 are installed on the vertical rod to complete the installation of the high-altitude scaffold.

After the scaffold is used, the main body of the scaffold can be dismantled first, and then the section steel cantilever beam; the process of dismantling the section steel cantilever beam is the process of dismantling the anchor. After the floor formwork is removed, gently tap the support rod of the anchor with a small hammer At the top, the bottom plate of the anchor and the support rod are ready to drop. Before tapping, screw the fastening nut on the external thread on the top of the support rod to avoid the deformation of the screw thread caused by direct tapping on the support rod, which will affect the later use.

In this embodiment, the length of the external thread provided on the top of the support rod of the anchor is 150mm, which is convenient for adjustment according to the thickness of different concrete floors.
