(1) Hollow slab plug: Some construction management units have studied so far that no one has solved this decoration problem well, and the prefabricated hollow slab plug cannot meet the requirements of the standard drawing. A common problem in the construction of steel structure warehouses is that when bricks are used to plug holes, the distance between the outer surface of the plug and the end surface of the board is too small, and then the cement mortar is used to dry it. After such fine aggregate concrete is poured, no key pin is formed at the end of the board, which affects the overall stability of the floor and roof. The correct approach should be to use a mortar block or brick block above M5.0 (MU5.0). The outer surface of the plug should be at a distance of 20-30mm from the end surface of the slab. The fine stone concrete technology can be directly used when pouring the end joints. Pour into this part of the hole to form a pin at the end of the board to ensure the overall structural stability of the building and roof.
(2) Hollow-core slab set-up: When the hollow-core slab is hoisted, it is often damaged (or even not set-up), which fails to meet the design requirements of the steel structure warehouse, resulting in instability of the prefabricated board, which seriously affects the floor, roof and wall Completeness. The quality control point is to determine the focus of construction management quality cost control, which is the sub-item project that has some problems in the general development of the brick-concrete structure.
In the construction stage of steel structure warehouse construction supervision, supervisors supervise the construction quality of key parts and key procedures throughout the process. This is what we call the behavior of side-by-side supervision. The quality of on-site supervision of reinforced concrete construction is particularly important in the whole process of supervision. In our on-site construction quality on-site supervision of reinforced concrete, in addition to the wealth of professional technical management skills that must be mastered, you should also make full use of the current laws and regulations to regulate and Improve our management behavior, improve the level of construction project management, and ensure construction quality. This article will analyze the construction management quality of cast-in-situ reinforced concrete by station supervision enterprises in three parts.
All prefabricated reinforced concrete construction must be controlled in advance to prevent the inherent quality of the project from appearing, so that quality problems, project quality, and resolution at an early stage reflect the quality of the project management plan. This is a side stop to ensure effective The premise of supervision.
The quality of the production and installation of the formwork will play an important role in ensuring the smooth appearance of the internal structure and components of the building concrete and steel reinforcement, the accuracy of the geometric model size, and the strength and rigidity of the social structure. The project quality and safety problems caused by template size error and poor support should be taken seriously.
The formwork and support should be designed according to the engineering structure form, load size, supporting surface structure category, construction equipment and material supply and other conditions. They must have sufficient bearing capacity, rigidity and stability to reliably bear the weight of the poured concrete, and the lateral pressure construction load .
