Description

Technical Field

[0001] The utility model relates to the field of formwork-free steel truss floor deck construction, in particular to a cutting tool for formwork-free steel truss floor deck. Background Art

[0002] At present, when floor decking is assembled on site, the width of the slab parallel to the steel truss is produced in one go according to the detailed drawings, while the width of the slab perpendicular to the steel truss generally adopts a unified standard modular 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 using 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 dimensions of modular floor decking with the design dimensions of the floor to be built (single concrete floor slab), pre-layout the floor decking installation, and then directly determine the theoretical width 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 deck and installing it until the last floor deck is installed. The Y width dimension of the last floor deck is measured and cut according to the actual installation dimensions on site.

[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 module, which leads to 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 10mm). The large gap between the plates during assembly and buckling 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 plate 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 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) Due to the lack of a 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 results in increased costs.

[0009] Taking into account the two common methods of on-site installation and cutting of traditional floor decking, both of which are low-standardization and tool-based, and absolutely rely on the workers' experience, resulting in increased difficulty in controlling cutting dimensions, poor cutting accuracy, and slow speed. The cutting dimension deviation makes the galvanized iron plate at the bottom of the floor decking insufficient to extend into the reserved dimension of the beam form, affecting the casting quality of the concrete floor slab. 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 practice for the rapid and precise on-site cutting of floor decking.

[0011] Therefore, in order to solve the above problems, a cutting tool for steel truss floor decking that does not require formwork removal 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.

The left retainer 1 and the right retainer 2 are used to form a supporting skeleton and determine the spacing between the left retainer 1 and the right retainer 2.

[0037] More precisely, the left retainer 1 has a left horizontal wing plate 3 extending laterally to the right, and a locking bolt 5 is provided on the left horizontal wing plate. The right retainer 2 has a right horizontal wing plate 4 extending laterally to the left, and a functional hole extending laterally is opened on the right horizontal wing plate 4. The locking bolt 5 passes through the functional hole, so that the left retainer and the right retainer can be connected with each other with an adjustable transverse spacing; the locking bolts 5 connecting the left retainer 1 and the right retainer 2 are at least two groups arranged at intervals in the transverse direction, so as to form a stable connection system without the occurrence of deviation or dislocation, and the structural stability is excellent and the cutting consistency is good;

The spacing adjustment is convenient and reliable; the adoption of this solution can be based on the actual required width of the on-site truss plate, and then the standard size of the floor decking can be accurately positioned, so that full-range cutting parallel to the direction of the steel truss can be achieved through the cutting equipment 7 set on the right retaining frame.
