Description
The technical field is as follows:
the utility model relates to a cast-in-place seam fixed knot of prefabricated wall panel constructs belongs to building prefabricated component installation built-in fitting.
Background art:
the prefabricated building refers to a building assembled on a construction site by using prefabricated components. The building has the advantages of high building speed, less restriction by climatic conditions, labor saving and building quality improvement.
Fabricated buildings have become of interest since the beginning of the 20 th century and have been realized through the sixties. The first attempts made in English, French, Soviet Union, etc. The assembly type building has high construction speed and low production cost, and is rapidly popularized and developed all over the world.
The characteristics of the fabricated building: 1. a large amount of building components, for example side fascia, interior wallboard, superimposed sheet, balcony, air conditioner board, stair, precast beam, prefabricated post etc. are all accomplished by workshop production and processing, and centralized production greatly reduced engineering cost also more does benefit to quality control simultaneously. 2. The building parts produced by the factory are transported to the site for assembly, so that the template engineering and the manual workload are reduced, the construction speed is accelerated, and the method has great significance for reducing the construction cost. 3. The assembly construction changes the whole building from one project to one product. The more standard the component, the higher the production efficiency and the lower the cost, and the performance price of the whole assembly type building is far comparable to that of the traditional construction mode by matching with the digital management of a factory. 4. Unlike traditional building, which has to finish the main body before decoration, the assembled building can complete the decoration of the prefabricated parts before assembling, so as to realize the synchronization between decoration project and main body project, reduce construction process and lower construction cost. 5. The building materials of the fabricated building are selected more flexibly, and various energy-saving and environment-friendly materials such as light steel and wood boards are applied, so that the fabricated building is more consistent with the concept of green buildings.
When a prefabricated component is installed on site, prefabricated parts need to be connected through extended steel bars, then a template is erected on a cast-in-place seam, concrete is poured into the erected template, the template and the template need to be pulled together in a pair manner through a pair of pull bolts in order to prevent the template from expanding, the existing cast-in-place seam fixing structure for the external wall panel is shown in figure 1 and comprises two aligned external wall panels, an inner template and an outer template are respectively attached to the inner side and the outer side of a gap between the external wall panels, a pair of pull screw rods penetrate through the two templates, nuts are sleeved at the two ends of the pair of pull screw rods, and the two templates are fixed; a closed gap is formed between the two templates and the two external wall panels, so that the cast-in-place gap of the prefabricated external wall panels is fixed, and the subsequent cast-in-place operation is facilitated; although the cast-in-situ seam template can be fixed by the design, an operator needs to build a scaffold outside the building main body for operation, so that the operation risk is increased, the measure cost is increased, the construction site environment is influenced, and the occupied area of a construction site is increased. The assembly type building has high cost, and the development of the market of the assembly type building is restricted to a certain extent.
