Special construction scheme for hanging basket of curtain wall project of a multi-storey residence
The main building of the project has 31 floors, (including the podium on the fourth floor) and two basement floors. Building area: the total building area is 51664 square meters, including about 42325 square meters above the ground (for commercial office space), about 8400 square meters underground (for underground parking and civil air defense works), and the total height of the building is 137 meters. The curtain wall of the main building facade and podium building will be constructed by hanging basket; Since the facade curtain wall is not in the same vertical plane, and the access distance is different, the hanging baskets will be erected stagger with 18F, 25F, 30F as platforms, and the construction will be carried out in sections; The construction will be carried out in the order of installing the keel from bottom to top and installing the panel from top to bottom, with the large surface first and then the closing installation and the installation of sporadic components. In terms of vertical transportation of materials, our company will use the existing machinery, equipment and devices of the general contractor for transportation;

concrete Cable tower construction scheme (multi-layer double row structure)
The erection of cable tower support in this project is carried out synchronously with the concrete height of cable tower. The erection of existing support is divided into three steps. The support is in the form of bowl buckle support, and the overall support system only bears the pedestrian load, not the lateral pressure during concrete pouring. Due to the high height of the main tower, how to ensure the firmness and stability of the scaffold and pedestrian ladder used by the construction personnel is a particularly important process in the project construction to ensure the safety of the construction personnel. Through careful analysis, the diameter of the scaffold and pedestrian ladder used by the construction personnel is proposed to be 48mm The scaffold steel pipe can be set up, and the layout position can be adjusted at will, effectively ensuring the verticality of the upright and the levelness of the cross bar, facilitating the connection and fixation with the tower column. It is connected into a whole through fasteners, with good firmness and stability. The support erection height of the project is equal to the concrete erection height. The erection is carried out in five times from the erection of the support to the completion of the concrete pouring of the overall cable tower.

A high-rise residential project in Beijing concrete construction plan
The basement floor is 400mm, 600mm and 700mm thick respectively, the concrete strength grade is C30, and the impermeability grade is S6. Because the foundation floor is constructed in sections, the concrete volume of each section is large, and the construction phase of the floor is winter construction. It is necessary to ensure that the continuous pouring of concrete will not delay the progress, and that the winter construction and maintenance can meet the concrete quality acceptance standards. It must go through a strict construction organization plan and adequate material preparation. This is the key construction content of the project. See the Foundation Slab Concrete Construction Scheme for details.

Chapter IV Construction preparation 4.1. Technical preparation 4.1.1. Control of alkali content in concrete below ± 0.000 First of all, there is flexible waterproof coiled material on the outside of the structure, which can prevent the outside environment from penetrating into the alkali in the concrete. In addition, control the alkali activity of aggregates and the alkali content of constituent materials. Alkali content=the amount of alkali brought in by cement (equivalent Na2O% percentage content × the amount of cement per cubic meter)+the amount of alkali brought in by additives+the effective alkali content in the admixture, so as to ensure that the total alkali content of concrete is less than 3Kg/m3. Therefore, reducing the amount of cement on the premise of ensuring the strength grade of concrete can reduce the alkali content. The commercial concrete company must provide the calculation sheet of concrete alkali content and Cl - content to our company.

Ceramsite of a project in Wuhan concrete construction plan
As a new type of lightweight aggregate concrete, ceramsite concrete has greatly reduced the self weight of the structure and the bearing load of the foundation. However, the construction technology of ceramsite concrete is more complex than ordinary concrete, especially the clay ceramsite has strong water absorption, and the control of the water content of concrete is very important. Therefore, the water consumption must be strictly measured when mixing concrete to control the slump of the ceramsite concrete into the mold and ensure the construction quality of ceramsite concrete.
