Background technique

Building industrialization and building industrialization are important approaches to the innovation of building construction models. The traditional structure is divided according to the materials used, mainly including mixed structure (such as brick-concrete structure), concrete structure (such as concrete frame structure, shear wall structure, frame-shear wall structure, cylinder structure, etc.), steel structure and wooden structures etc. Among them, concrete structures account for a large proportion of the entire building system, and the use of prefabricated concrete structures is an important way to realize the industrial production of concrete structures. the

Prefabricated concrete structure (building) is a reinforced concrete structure (building) in which part or all of the main structure is assembled with prefabricated concrete components. For example, the prefabricated fully prefabricated shear wall structure adopts a shear wall structure in which the inner and outer walls are prefabricated or the joint parts are cast-in-place; while some prefabricated shear wall structures adopt the inner wall cast-in-place, and all or part of the outer walls are prefabricated and the joint parts are cast in place. Cast-in-place shear wall structure. For prefabricated concrete structures, factory-produced prefabricated components such as beams, columns, walls, floors, etc., are hoisted and installed on site, and installation quality inspection and acceptance are very important. For example, for vertical structural components such as columns and walls, the installation process needs to check its elevation, center displacement, verticality, etc. Prefabricated concrete structures, especially fully prefabricated concrete structures, have a large number of vertical component walls and columns. During the installation process, how to accurately position them in place to ensure that the center displacement and vertical verticality of the vertical component installation meet the requirements, It is necessary to adopt auxiliary positioning measures for rapid positioning, and to ensure that its position is accurate and vertical verticality meets the requirements, which is a technical problem that needs to be solved during the installation of prefabricated concrete structural components. Regarding the construction technology, hoisting technology, installation technology and quality inspection and acceptance of prefabricated concrete structures, it is urgent to study and solve related technical measures in construction practice. the

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and embodiments. the

As shown in Figure 1, a prefabricated concrete vertical component fast installation and positioning device includes a fixed base 3, and a vertical ruler 5 whose lower end is perpendicular to the fixed base 3 and one end of the fixed base 3 is fixed together. The base 3 is welded together with the vertical support ruler 5, in order to ensure that they intersect vertically and not be deformed for a long time during use, an oblique reinforcement 7 is used for reinforcement therebetween. The oblique reinforcement 7 is welded and reinforced with a 6 mm thick right-angled triangle steel plate in the embodiment. A base level tube 4 is installed on the fixed base 3, a vertical level tube 6 is installed on the vertical ruler 5, and at least two base position adjustment devices for adjusting the position of the fixed base are installed at the lower end of the fixed base 3. the
