Description

Technical Field

[0001] The invention relates to the field of formwork-free steel truss floor deck construction, and in particular to cutting equipment and a construction method for formwork-free steel truss floor deck. Background Art

[0002] At present, when floor decking is assembled on site, the width of the slab along the direction parallel to the steel truss is produced by the manufacturer in one go according to the detailed drawings, and the width of the slab perpendicular to the steel truss generally adopts a unified standard module size (for example: 600mm); the size of the floor decking produced by the manufacturer in a modular manner is Xmm (width parallel to the steel truss) * Ymm (width perpendicular to the steel truss), and is installed on site with a single concrete floor slab as the assembly unit according to the detailed drawings.

[0003] In traditional construction, there are generally two ways to cut floor decking. One is to compare the standard size of modular floor decking with the design size of the floor slab to be built (single concrete floor slab), pre-layout the floor decking installation, and then directly determine the theoretical width size of the last floor deck on the floor slab, and pre-cut directly; the other is to assemble the modular floor decking first and then cut it, starting from the first floor decking and installing it until the last floor decking is installed. According to the actual installation size on site, the size of the tail floor deck in the Y width direction is measured and cut.

[0004] Both methods are currently in use, but there are many problems during on-site cutting:

[0005] (1) When the first method is used for sizing and cutting, it is difficult to control the dimensional accuracy. The width of the end floor deck is determined according to the theoretical value of the floor deck modulus, resulting in a large error. This method is greatly affected by installation factors, and the length of the galvanized iron plate at the bottom of the floor deck extending into the beam template is designed to be small (generally 10 mm). The gap between the plates during assembly and buckling is large, which will lead to a large cumulative error in the final assembly. At the same time, the deviation during cutting will also increase the error.

[0006] (2) When the second method is used for cutting, it is difficult to control the measurement accuracy of the cutting size of the end floor decking. Generally, the entire board needs to be cut with measurement points at both ends and cutting lines drawn. The overall speed is slow and the accuracy is low, resulting in insufficient length of the galvanized iron plate on the cutting surface of the end of the floor decking extending into the beam template or a large cutting deviation.

[0007] (3) The common problems of the two current cutting methods are slow speed, low precision and poor molding quality;

[0008] (4) Since there is no professional and fixed construction method, the quality control of this process requires a high level of professionalism from the workers, which increases the quality requirements of the labor force and causes increased costs.

[0009] Taking into account the two common methods of on-site installation and cutting of traditional floor decking, both of them are low-standardized and tool-based, and absolutely rely on the workers' experience. This leads to problems such as increased difficulty in controlling the cutting size, poor cutting accuracy, and slow speed. The cutting size deviation makes the galvanized iron plate at the bottom of the floor decking insufficient to extend into the beam mold, affecting the quality of the concrete floor casting. In addition, the traditional construction method is slow, which has a certain impact on the installation period.

[0010] Taking all factors into consideration, there is currently no standardized approach for fast and precise on-site cutting of floor decking.

[0011] Therefore, in order to solve the above problems, a cutting equipment and construction method for steel truss floor decking that does not require demolding is needed, which can achieve precise control of the cutting size of the floor decking on the basis of low operating difficulty, improve the casting quality of the concrete floor slab, improve construction efficiency, and speed up the construction progress.
