Description

Technical Field

[0001] The utility model relates to the technical field of scaffolds, in particular to a scaffold steel pipe crossbeam structure imitating a T-shaped material. Background Art

[0002] During the construction or repair of ships, it is often necessary to set up scaffolding as a temporary platform for auxiliary construction work in consideration of construction safety, convenience and cost. Generally, scaffolding is set up from the flat and solid ground or steel plate below, or scaffolding can be set up in a suspended or inverted form after taking special measures. When it is necessary to set up scaffolding in a small range or local construction, such as in the side tanks on the side of the ship, the cabins in this area are characterized by being high and long, and also belong to limited space. The accessible passages are often a few 60x80 cm manholes, and the required material handling can often only be done manually. Due to the particularity of the cabin, when carrying out local construction on the top of the side tank, a small range of scaffolding is required. Setting up scaffolding from bottom to top requires too much scaffolding materials, resulting in high production costs. If the scaffolding is suspended, a sufficiently rigid beam is required as support. For example, angle steel, channel steel, H-shaped steel and other steel beams can meet the construction requirements. However, angle steel, channel steel, H-shaped steel and other steel beams are relatively heavy. For example, a 6-meter-long H-shaped steel 300*100*10 / 12 weighs more than 200 kilograms, which is difficult to carry manually. At this time, the help of other mechanical equipment is needed. Because the environment is in a relatively closed space, the use of mechanical tools is limited, such as only a hand hoist can be used; or by opening holes to change the spatial structure and then using a crane to hoist the steel, it is inevitable that the production and construction will be cumbersome and the cost will increase; even in the subsequent scaffolding disassembly process, the steel is often destructively cut short for easy handling, wasting materials, resulting in excessively high production costs. Summary of the invention

[0003] The utility model provides a scaffolding steel pipe crossbeam structure imitating a T-shaped material in order to overcome the deficiencies of the prior art.

[0004] In order to achieve the above purpose, a scaffolding steel pipe beam structure imitating a T-profile is designed, which is characterized by comprising relatively arranged pressure plates and clamping plates, one side of the lower end of the clamping plate is rotatably connected to the pressure plate, and the upper end of the clamping plate is connected to the upper end of the pressure plate by bolts, and a accommodating cavity is formed between the connected clamping plates and the pressure plates.

[0005] The pressing plate comprises a panel 1, a panel 2 and a web arranged in a U shape. The panel 1 and the panel 2 are arranged in parallel, and one end of the clamping plate extends between the panel 1 and the panel 2.

[0006] A groove 1 is arranged on the side of the panel 1 and the panel 2 away from the web, and a groove 2 is arranged on the side of the clamping plate close to the panel 1 and the panel 2.

[0025] The utility model is further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 8 As shown, the pressure plate and the clamping plate are arranged relative to each other, one side of the lower end of the clamping plate 2 is rotatably connected to the pressure plate 1, and the upper end of the clamping plate 2 is connected to the upper end of the pressure plate 1 by bolts 4, and a receiving cavity 3 is formed between the connected clamping plate 2 and the pressure plate 1.

[0027] The pressure plate 1 includes a panel 1-1, a panel 2 1-2, and a web 1-3 arranged in a U shape. The panel 1-1 and the panel 2 1-2 are arranged in parallel, and one end of the clamping plate 2 extends between the panel 1-1 and the panel 2 1-2.

[0028] A groove 1-4 is provided on the side of the panel 1-1 and the panel 2 1-2 away from the web 1-3, and a groove 2-1 is provided on the side of the clamping plate close to the panel 1-1 and the panel 2 1-2.

[0029] The number of grooves 1-4 is one or more, and the number of grooves 2-1 matches the number of grooves 1-4. In this embodiment, the number of grooves 1-4 is two, which are respectively arranged on the upper and lower sides of the pressing plate 1, and the number of grooves 2-1 is two, which are respectively arranged on the upper and lower sides of the card plate 2. The accommodating cavity 3 formed after splicing is as shown in FIG. Figure 1 shown.

[0030] A through hole 1-5 is provided at one side of the lower end of the pressing plate 1, and a through hole 2-2 is provided at one side of the lower end of the clamping plate 2. The movable shaft 5 passes through the through hole 1-5 and the through hole 2-2 to rotatably connect the pressing plate 1 and the clamping plate 2.

[0031] The upper end of the clamping plate 2 is connected to the hinge fixing seat 2 - 3 , the hinge fixing seat 2 - 3 is connected to one end of the bolt 4 , and the other end of the bolt 4 is connected to the pressing plate 1 and is fastened by a nut 6 .

[0032] The web 1-3 upper end is provided with a groove 3 1-6 for the bolt 4 to pass through. The width of the groove 3 1-6 is less than the nut 6.

[0033] The accommodating chamber 3 is provided with steel pipes 7. Adjacent steel pipes 7 are connected by scaffold fasteners 8.

[0034] In this embodiment, the bolt 3 is a movable bolt. The card plate is a steel plate with a thickness of 20-30 mm. A through hole 2-2 is provided on the lower end of the card plate 2 for connecting and rotating the movable shaft 5 and the pressing plate 1. A hinge fixing seat 2-3 is welded on the upper end of the card plate 2 for connecting the fixing bolt 3. A through hole 1-5 is provided on the lower end of the web 1-3 of the pressing plate 1. The pressing plate 1 and the card plate are connected through the movable shaft 5 to form a hinge structure, so that the card plate and the pressing plate can be rotated, and a reaction force is provided for the self-locking steel pipe at the upper end of the card plate.

[0035] When the utility model is used, Figures 9 and 10 As shown, a plurality of straight steel pipes 7 are passed through the accommodating cavity 3 formed by two or more groups of pressing plates 1 and clamping plates 2, and the bolts and nuts are pre-tightened so that the pressing plates 1 and clamping plates 2 press the steel pipes and assemble them into a whole, which effectively increases the rigidity of the beam structure. When the length of the steel pipe 7 is insufficient, the scaffolding fasteners 8 are used to partially lengthen the steel pipe so that the length of the steel pipe beam meets the needs of on-site production.

[0036] When in use, select the appropriate length of the scaffolding steel pipe according to the distance between the two supporting points on site, fix the pressing plate and the card plate on the supporting point, adjust the distance between the nut 6 and the bolt 4, so that the pressing plate and the card plate rotate through the movable shaft, thereby pressing the top two steel pipes 7, and then pressing all the steel pipes 7 below. The number of card plates and pressing plates is added to the steel pipe between the two supporting points according to the actual situation to form a rigid beam, and finally the scaffold to be erected is placed across the beam to achieve the purpose of erecting the scaffold in the air.

[0037] For the convenience and safety of construction, the maximum length of a single scaffolding steel pipe is 6 meters, and the weight is about 23 kilograms. It is thin and long, and the bending resistance of the scaffolding steel pipe is weak when supported by the two end fulcrums. The utility model bundles multiple steel pipes 7 together through the cooperation of several groups of card plates and pressure plates, and makes them thicker and longer, so that each scaffolding steel pipe 7 is evenly stressed, greatly improving its bending rigidity, and forming a component with basically the same rigidity and strength as the profile, so as to meet the requirements of scaffolding suspended erection. In addition, the structure of the utility model can be disassembled, from heavy to light, which is convenient for construction and also conducive to repeated use.
