Angle steel guide rail device for controlling flatness of floor and method

Abstract

The invention belongs to the technical field of floor construction and particularly relates to an angle steel guide rail device for controlling the flatness of a floor. The angle steel guide rail device is characterized in that the angle steel guide rail device comprises a pair of guide rails which are arranged parallelly and symmetrically and a level ruler placed on the guide rails; each guide rail comprises angle steel arranged in an inverted-V shape, and a plurality of supporting frames are evenly welded to the lower portions of the angle steel, are each of a n-shaped structure and comprisesupporting steel bars, supporting steel plates and screw rods; and the screw rods are welded to the two ends of the lower surfaces of the supporting steel plates correspondingly, nuts are screwed onall the screw rods correspondingly, and the supporting steel bars are welded to all the nuts correspondingly. The angle steel guide rail device is easy to manufacture, materials are easy to find, using is also convenient, and the guide rails are simply dismantled.

Description

technical field [0001] The invention belongs to the technical field of floor construction, and in particular relates to an angle steel guide rail device and method for controlling the flatness of the floor. Background technique [0002] At present, large-scale building structures such as large shopping malls, airports, underground garages, industrial plants and warehouses are constantly emerging in China. These buildings have high requirements on the flatness of the floor, and often require the flatness of the floor to be controlled within ± 2mm per two meters. At present, the commonly used method is to use laser leveling machines, but the cost of laser leveling machines is too high at this stage. However, the effect of conventional process flatness is often in the hands of workers, and the technical requirements for workers are very high. [0003] Although there are many flatness control devices and methods in the prior art, there are some defects, such as the difficulty i...

Problems solved by technology

These buildings have high requirements on the flatness of the floor, and often require the flatness of the floor to be controlled within ± 2mm per two meters. At present, the commonly used method is to use laser leveling machines, but the cost of laser leveling machines is too high at this stage. However, the effect of conventional process flatness is often in the hands of workers, which requires high technical skills for workers.

[0003] Although there are many flatness control devices and methods in the prior art, there are some defects, such as the difficulty in processing and installing guide rails, and the fact that guide rail devices for floor construction are easy to accumulate and take away a large amount of concrete when taking out the concrete.

For example, a large-area wear-resistant floor flatness and elevation control method (application number 200810180005.1) has the following problems: 1. It takes time and effort to stake out and drill holes on the cushion; 2. It is easy to place the angle steel in an "L" shape. It is easy to take away the concrete when the accumulated concrete is taken out; 3. The bolts are fixed by drilling, and the width of the angle steel is limited. After the angle steel is drilled, the integrity of the angle steel cannot be guaranteed.

For example, an efficient leveling method for large-area concrete floor construction (application number 201210371667.3) has the following problems: 1. It takes time and effort to implant the support reinforcement into the ground; 2. When welding the horizontal bridge reinforcement on the support reinforcement, it is required to control the elevation. Difficult to perform, time-consuming and labor-intensive

Another example is a channel steel guide rail and its method for controlling the elevation of the floor (application number 201310018276.8). Using this method to make a channel steel guide rail, concrete will accumulate in the channel steel, and a large amount of concrete will be taken away when the guide rail is taken out, which will increase the difficulty of taking it out.
