Description

Elevation-adjustable super-flat floor partition seam protection formwork system

technical field

The invention relates to a device in the technical field of construction engineering, in particular to an elevation-adjustable super-flat floor compartment seam protection formwork system.

Background technique

Because the load on the floor in actual use is very complicated, and the quality of the foundation is not easy to guarantee during construction, the floor becomes the most problematic building part in actual use. As the owners pay more attention to the quality of the floor, more and more attention is paid to the design and construction technology of the floor, especially the construction technology directly determines the quality of the floor. The construction method of separate jump pouring is commonly used in floor construction, that is, the floor to be constructed is divided into larger rectangular blocks with formwork, and the concrete is poured in jumper grids; after the concrete poured in jumper grids shrinks and solidifies, the formwork is removed; Concrete in the grid; after all the concrete is poured and solidified, use a cutting blade to cut the sub-storey joints to a depth of one-third of the thickness of the floor slab. Wooden formwork is commonly used for floor formwork, holes are dug in the formwork, and pins and bolts are inserted on site to transmit shear force. This traditional construction method brings the following construction defects:

1. Because the foundation on the site is generally not carefully leveled, the height control of the wooden formwork becomes a problem, and it is difficult to guarantee the high precision of the floor construction standard, and it is difficult to reach the millimeter level;

2. On-site manual installation of wooden formwork is time-consuming and laborious, and the construction speed is slow;

3. There is no seam protection for the sub-compartment seams after completion. Due to the rolling of the wheels of the vehicle during use, the sub-compartment seams are easily damaged and have poor durability. Moreover, it is generally inaccurate to cut the seams of the bins with a cutting blade, and it is easy to have double seams (commonly known as double eyelids), resulting in parallel shrinkage cracks on the seams of the bins;

4. Since there is no separate warehouse joint steel formwork to protect the floor and strengthen the bond between the floor and concrete, the deformation of the floor slab is uneven during the later shrinkage process, and the slab is easy to crack.

After searching the existing technical literature, it is found that the Chinese patent application number is 200620162315.7, and the patent name is: Elevation Adjustable Super Flat Floor Formwork. This device is suitable for floor formwork construction, and the formwork height can be adjusted. But this device cannot be industrialized production, and the quality of installation and use varies with the technical level of workers. There are too many components installed on site, and the installation speed is full, so it is difficult to achieve better construction quality. And the steel formwork of this device is dismantled after construction, can not provide the steel formwork protection of sub-store seam edge, can not improve the durability of sub-store joint, can not avoid double seam phenomenon, can not avoid the uneven deformation of floor and crack in the plate. In short, items 2, 3, and 4 in the above-mentioned problems cannot be solved well.
