Example Embodiment

[0080] Embodiment 1, a prefabricated shear wall superimposed structure system that is easy to install, including vertical member connection and horizontal member connection, such as figure 1 with figure 2 As shown, both the vertical and horizontal members include a hollow prefabricated laminated concrete shear wall 1 and a prefabricated floor slab 3. The hollow prefabricated laminated concrete shear wall 1 includes two symmetrically arranged thin shear walls 1-1, The two thin shear walls 1-1 are connected by truss reinforcement 2-3. Such as Picture 9 As shown, the vertical abutting surfaces on both sides of the hollow prefabricated laminated concrete shear wall 1 are provided with a plurality of shaped anchor bars 2-2 or a plurality of bent anchor bars 2-1, the ends of the bent anchor bars 2-1 The bending angle of the part is 135°.

[0081] Such as Image 6 As shown, the lower end surface of the hollow prefabricated laminated concrete shear wall 1 is provided with several annul...

Example Embodiment

[0085] Embodiment 2, an installation method of a prefabricated shear wall superimposed structural system that is easy to install, includes vertical member installation and connection and horizontal member installation and connection, and the vertical member installation and connection process is as follows Figure 4-8 As shown, including the following steps:

[0086] Step 1: Such as Figure 4 As shown, the hollow prefabricated laminated concrete shear wall 1 is installed and fixed on the lower layer, and concrete is poured between the two thin shear walls 1-1 until the concrete is 10-20 cm from the top of the thin shear wall.

[0087] Step 2: Vertically hoist the prefabricated floor slab 3, so that the bent anchor steel bars 2-1 on the upper part of the hollow prefabricated laminated concrete shear wall 1 and the bent anchor steel bars 2-1 at the end of the prefabricated floor 3 described in step 1 Interlock with each other, such as Figure 5 Shown.

[0088] Step 3: Install the uppe...

Example Embodiment

[0101] Embodiment 3 is an installation method of a prefabricated shear wall superimposed structure system that is easy to install. The T-shaped connection includes a T-shaped outer loop rib buckle method and a T-shaped direct buckle method. The T-shaped outer loop The buckle is legal as Picture 12 As shown, including the following steps:

[0102] Step 13: The three-page hollow prefabricated laminated concrete shear wall 1 is hoisted in place, so that the three-page hollow prefabricated laminated concrete shear wall 1 forms a T-shaped position.

[0103] Step 14: Place ring steel bars 4 at the butt ends of the three-page hollow prefabricated laminated concrete shear wall 1 described in step 13. There are two ring steel bars 4, and the two ring steel bars 4 constitute T-shaped composite bars. The three ends of the T-shaped composite bars are respectively buckled on the annular anchoring bars 2-2 of the three-page hollow prefabricated laminated concrete shear wall.

[0104] Step 15: In...

Abstract

The invention discloses an easy-to-install assembled shear wall composite structure system and an installation method thereof. The technical problem that the existing assembled shear wall structure has the disadvantages of complicated connection of components, difficult construction and poor integrity and waterproof performance is solved. The assembled shear wall composite structure system comprises vertical component connection and horizontal component connection. Both vertical components and horizontal components include hollow prefabricated composite concrete shear walls and prefabricated floor slabs. The hollow prefabricated composite concrete shear walls are horizontally connected and vertically connected. The prefabricated floor slabs are horizontally connected to the top end of thehollow prefabricated composite concrete shear wall on each floor. Each hollow prefabricated composite concrete shear wall includes two symmetrical thin shear walls. Bent anchorage bars buckled to thecorresponding hollow prefabricated composite concrete shear wall are arranged around each prefabricated floor slab. The assembled shear wall composite structure system has the advantages of simple construction, high construction efficiency and good waterproof performance, and has a good popularization and application prospect.

Description

technical field [0001] The invention relates to the technical field of prefabricated building construction, in particular to a prefabricated shear wall superimposed structure system and an installation method that are easy to install. Background technique [0002] The prefabricated shear wall structure is a type of prefabricated concrete structure, which is defined as a prefabricated concrete structure in which the shear walls, beams, and slabs of the main force components are partially or entirely composed of prefabricated concrete components. When the traditional prefabricated ring bars are fastened and anchored to the concrete shear wall structure for vertical connection, after the upper and lower walls are in place, the horizontal steel bars need to be penetrated. Every time the horizontal steel bars pass through a certain distance, they will be blocked, requiring workers to carry out time-consuming work. Laborious manual adjustment makes the installation very difficult ...
