Problems solved by technology

[0004] In the construction process of the cast-in-place reinforced concrete floor slab of the residence, in order to control the thickness of the floor slab, various preventive measures have been taken on the construction site, including the cable control method, the pre-embedded reinforcement method, the standard card method and the standard horse stool method. In addition, A control method for the thickness of the cast-in-place floor slab was also proposed from the construction technology and management, but under the current construction technology and unscrupulous management methods, the above preventive measures often cannot effectively control the thickness of the floor slab, cannot guarantee the quality of the project, and waste materials and manpower

Embodiment 1

[0053] Example 1, see Figure 1-Figure 10 , Figure 17 to Figure 19 , the floor formwork or floor slab construction control method provided by the present embodiment, it comprises the following steps:

[0054] (1) Prepare a special calibration ruler 1 and a reference line rope 2; on the special calibration ruler 1, the construction reference correction point 12 of the floor template 7 or the floor slab 8 is preset, and the correction point 12 is vertical to the bottom of the special calibration ruler 1 The distance is equal to the vertical distance from the construction datum point 32 of the column steel bar to the upper surface of the floor template 7 or the floor slab 8; two nails 13 are horizontally set on the special calibration ruler 1, and the nail points of the two nails 13 are respectively the floor template 7 or the floor slab 8. Correction point 12 for floor 8 construction;

[0055] (2) Determine the elevation of the floor template 7, or the pouring thickness of th...

Embodiment 2

[0066] Example 2, see Figure 11 to Figure 19 The floor formwork or floor slab construction control method and the special calibration ruler 1 provided in this embodiment are basically the same as the steps, method and structure of embodiment 1. The difference is that the floor formwork or floor slab construction control method is also used for rectangular beams. 5 or formwork installation or pouring construction of ground beam 6.

[0067] see Figure 11 to Figure 13 , is a schematic diagram of the structure used for the rectangular beam 5 formwork construction and the elevation and flatness control of the inversion.

[0068] see Figure 14 to Figure 16 , is a schematic diagram of the structure used for the construction of the ground beam 6 formwork and the inverted elevation and flatness control. A ground beam 6 concrete cushion 61 is provided under the ground beam 6 .

[0069] In the above embodiments, the floor formwork correction point is set below the floor slab corre...

Abstract

The invention discloses a building formwork or floor slab construction control method. The method is characterized by comprising the following steps: (1) preparing special straightedges and datum cords; (2) determining elevation of a building formwork or pouring thickness of a floor slab, and marking construction datum points on column steel bars; (3) marking construction datum points on other column steel bars; (4) connecting the construction datum points via the datum cords to mesh structures positioned on the same plane so as to form a datum plane for construction, wherein the mesh datum cords are construction data of the building formwork or floor slab; (5) after the building formwork is mounted or the floor slab is poured, correcting mounting and construction accuracy of the building formwork or floor slab with the special straightedges to realize elevation control and flatness control of building formwork mounting or floor slab pouring. The invention further discloses the special straightedge for implementing the control method. By the method, efficient and accurate building formwork mounting construction or floor slab pouring construction is realized, and elevation and flatness control of construction is realized.

Description

technical field [0001] The invention relates to the technical field of building engineering construction benchmarks and construction control, in particular to a construction control method of a building template or a floor slab and a special calibration ruler. Background technique [0002] At present, when building a building in China, the formwork is generally made first, and cement is poured on the formwork to form the first floor slab. After the cement is solidified and cured, support columns are built on the first floor slab, and the second floor formwork is built on the support columns. Continue to pour the cement of the second floor slab on the second floor formwork. Repeat the above operations until the height of the high-rise building reaches the set height. Therefore, the quality of the installation and construction of the floor formwork and the pouring construction of the floor slab will directly affect the construction quality of the entire building. [0003] Ho...
