Description

An elevating scaffold pole connection structure

technical field

The utility model relates to the field of building construction, in particular to a connection structure for connecting upright poles of building lifting scaffolding.

Background technique

Scaffold refers to various supports set up on the construction site for workers to operate and solve vertical and horizontal transportation. In some large construction sites, steel scaffolding is generally used, which has stronger stability and higher safety.

The height of scaffolding is determined by the poles. In large construction sites, the height is generally higher, and the commonly used poles cannot reach the required height. Usually, multiple poles are connected to achieve the required height. In the prior art, the connection of the upper and lower vertical rods generally adopts a joint connection. For example, a connecting rod is arranged in the middle of the upper and lower vertical rods. The diameter is larger than the outer diameter of the upper and lower vertical rods. When in use, insert the connecting rod into the lower vertical rod, and then insert the upper vertical rod on the connecting rod. Since the middle part of the connecting rod protrudes, the upper vertical rod can stand on the connecting rod to achieve The purpose of connecting the upper and lower poles. Although this receiving type connection method has a simple structure and is convenient for disassembly and assembly, it also has the disadvantages of poor stability and low strength.

Contents of the invention

The purpose of the utility model is to provide a structure-stable and easy-to-operate elevating scaffold pole connecting structure.

In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a connection structure of a lifting scaffold pole, including an upper pole, a lower pole and a connecting piece connecting the upper pole and the lower pole. The upper vertical rod is a hollow square tube, the lower vertical rod is a hollow square tube, the connecting piece includes a connecting rod, and the upper vertical rod and the lower vertical rod are respectively sleeved on both ends of the connecting rod. Two first bolts are pierced on the pole, and two second bolts are pierced on the lower pole. The first bolts pass through the upper pole and the connecting rod, and the second bolts pass through the lower pole. The rod and the connecting rod, the first bolt and the second bolt are vertically arranged.

In the above technical solution, first through holes corresponding to the first bolts are provided on the two opposite surfaces of the upper vertical rod, and first through holes corresponding to the first through holes are provided on the connecting rod. Inner through hole, the first bolt passes through the first through hole, and the first inner through hole locks the upper vertical rod and the connecting rod; The second through hole, the connecting rod is provided with a second inner through hole corresponding to the second through hole, the second bolt passes through the second through hole, and the second inner through hole connects the lower vertical rod Locked with connecting rod.

In a preferred technical solution, the outer diameter of the connecting rod matches the inner diameter of the upper vertical rod and the lower vertical rod. The outer diameter of the connecting rod fits the inner diameter of the upper and lower vertical rods, making the overall structure more stable.

In a preferred technical solution, the connecting rod is a hollow square tube.

Due to the application of the above-mentioned technical solutions, the utility model has the following advantages compared with the prior art:

1. The utility model has the advantages of simple structure, strong stability, convenient disassembly and assembly, and is convenient for installation, maintenance and replacement during construction;

2. The first bolt and the second bolt of the utility model are vertically arranged, so that the force of the connecting rod is more uniform, and the whole connection structure is firmer;

3. The utility model has few accessories, is easy to produce, and reduces production cost and installation time.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Embodiment one:

As shown in Figure 1-3, a lifting scaffold pole connection structure, including the upper pole 1, the lower pole 2 and the connecting piece connecting the upper pole 1 and the lower pole 2, the upper pole 1 is a hollow square tube , the lower vertical rod 2 is a hollow square tube, the connector includes a connecting rod 3, the upper vertical rod 1 and the lower vertical rod 2 are respectively sleeved on both ends of the connecting rod 3, and the upper vertical rod 1 is pierced with two first bolts 4. There are two second bolts 5 on the lower pole 2, the first bolt 4 passes through the upper pole 1 and the connecting rod 3, the second bolt 5 passes through the lower pole 2 and the connecting rod 3, the first bolt 4 and the second bolt 5 are vertically arranged.

The first through hole corresponding to the first bolt 4 is provided on the opposite two faces on the upper vertical rod 1, and the first inner through hole corresponding to the first through hole is provided on the connecting rod 3. The first bolt 4 Through the first through hole and the first inner through hole, the upper vertical rod 1 and the connecting rod 3 are locked; the two opposite surfaces of the lower vertical rod 2 are provided with second through holes corresponding to the second bolts 5, and the connection The rod 3 is provided with a second inner through hole corresponding to the second through hole, and the second bolt 5 passes through the second through hole and the second inner through hole to lock the lower vertical rod 2 and the connecting rod 3 .

The inner diameter of connecting rod 3 outer diameters matches with upper vertical rod 1, lower vertical rod 2. The outer diameter of the connecting rod 3 fits with the inner diameter of the upper and lower vertical rods 2, so that the overall structure is more stable.

Connection method of upper and lower poles 2:

Place the lower end of the connecting rod 3 on the upper end of the lower vertical rod 2, match the second through hole and the second inner through hole one by one, pass the two second bolts 5 through the second through hole and the second inner through hole respectively, and place the Lock the lower vertical rod 2 with the connecting rod 3; put the lower end of the upper vertical rod 1 on the upper end of the connecting rod 3, match the first through hole and the first inner through hole one by one, and pass the two first bolts 4 respectively The first through hole and the first inner through hole lock the upper vertical rod 1 and the connecting rod 3; finally adjust the first bolt 4 and the second bolt 5 and lock them.

The first bolt 4 and the second bolt 5 of the present invention are arranged perpendicular to each other, so that the force on the connecting rod 3 is more uniform, and the entire connection structure is firmer and more stable.
