Compared with the existing special-shaped building formed by splicing precast gypsum, the special-shaped building manufactured by the foamed water bendable forming gypsum base plate can greatly reduce the stress inside the special-shaped building, ensure that the special-shaped building is stably fixed on a wall body of a house, ensure that the special-shaped building with good effect is displayed, and have no potential safety hazard in the construction process of the special-shaped building.
Preferably, when the gypsum substrate is nailed, the gypsum substrate is nailed every 15-30 cm apart in the longitudinal and lateral directions so that the distance between two adjacent fastening nails does not exceed 30cm, thereby ensuring that the gypsum substrate is stably fixed to the frame.
In the actual construction process, the special-shaped building needs to be installed on the built house wall, the actually built house wall is different from the originally designed house wall, and the building of the special-shaped building according to the originally designed three-dimensional model of the special-shaped building can cause the interference between the special-shaped building and the actually built house wall, so that the three-dimensional model of the special-shaped building needs to be reasonably modified based on the actual house wall.
Preferably, before the steel structure and the framework are constructed in the step a200, a 3D mapping machine is used to scan and model a construction site, so as to form a three-dimensional model of a house wall according to a house wall which is actually constructed, combine the three-dimensional model of the special-shaped building with the three-dimensional model of the house wall, check whether an unreasonable part exists in the combined three-dimensional model, and form a checked three-dimensional model of the special-shaped building, so that the steel structure and the framework can be constructed according to the checked three-dimensional model of the special-shaped building, thereby ensuring that the three-dimensional model of the special-shaped building can exhibit a good effect on the house wall.
For example, when the three-dimensional model of the special-shaped building is combined with the three-dimensional model of the house wall, an interference situation occurs in the three-dimensional models, that is, the two three-dimensional models are overlapped and crossed, and at this time, the three-dimensional model of the special-shaped building or the three-dimensional model of the house wall needs to be modified (in the modification process, the three-dimensional model of the special-shaped building or the three-dimensional model of the house wall can be modified, and considering that the house wall has been built, the three-dimensional model of the special-shaped building is modified mainly aiming at the unreasonable position of the house wall, and the three-dimensional model of the special-shaped building is modified according to the situation), so that the special-shaped building can be normally built on the house wall, and the special-shaped building is guaranteed to present a good effect.
Specifically, when the special-shaped building is built, the framework and the steel structure of the special-shaped building can be divided, the special-shaped building framework and the steel structure are divided into a plurality of smaller units, and all the units are assembled by splicing after all the units are manufactured, so that the integral framework and the steel structure of the special-shaped building are formed.
The steel structure is used for being installed to a house wall body and is a main part for connecting a special-shaped building and the wall body. The skeleton is arranged in a steel structure and forms an integral framework of the profiled building. The water-soaking bendable shaping gypsum substrate is fixed on the framework and is directly observed by people as the appearance of a special-shaped building. Separate the skeleton and the steel construction of whole dysmorphism building for a plurality of units to arrange the serial number to the position that a plurality of units correspond special-shaped building, treat all units and all accomplish the back, assemble all units according to the serial number, thereby form the skeleton and the steel construction of special-shaped building, again with bubble water flexible design gypsum base plate cladding outside the skeleton of special-shaped building, finally form special-shaped building. The special-shaped building is divided and manufactured independently, the originally designed three-dimensional model can be manufactured with high precision, and the manufactured special-shaped building can show the originally designed effect. In addition, the special-shaped building is divided into a plurality of units and then assembled for construction, so that the management efficiency can be greatly improved, the construction period can be shortened, the three-dimensional model of the special-shaped building is formed by combining the three-dimensional models based on the actual construction site, the three-dimensional model can be restored one by one, production data can be provided for site installation, the production and installation accuracy can be greatly improved, the installation is simple, and site assembly line operation can be performed. Because the special-shaped building is formed by coating the water-soaking bendable shaping gypsum substrate, the special-shaped building can not generate secondary stress release after being formed, and can not deform, crack or distort in the later period.
