Description

Technical Field

[0001] The invention belongs to the technical field of prefabricated building construction, and particularly relates to an installation and fixing device and an installation method for a precast bay window. Background Technique

[0002] At present, in prefabricated buildings, precast bay windows are generally connected and fixed by embedded pull rings. Since the pull rings are extremely prone to displacement during the concrete pouring process, it is impossible to ensure reasonable pull nodes after the precast bay window is hoisted. When tying steel bars and performing other construction operations on the precast bay window, it is extremely easy to cause the precast bay window to shake, resulting in displacement and the risk of overturning of the precast bay window. Pouring the concrete of the upper floor slab will also cause disturbance to the precast bay window. At this time, the precast bay window cannot be adjusted again, and only the precast bay window can be chiseled and repaired later, which will consume huge repair costs, and the chiseling also affects the integrity of the precast bay window structure. Summary of the Invention

[0003] The purpose of the invention is to provide an installation and fixing device and an installation method for a precast bay window, which can connect and fix the precast bay window after hoisting, and the positioning is accurate without deviation; avoid the workload of secondary cutting of the embedded pull rings in the later stage, greatly reduce the risk of overturning of the precast bay window, and ensure the installation quality of the precast bay window.

[0004] To achieve the above invention purpose, the invention provides an installation and fixing device for a precast bay window, including a first embedded sleeve, a second embedded sleeve and a pull rod that can adjust its own length; the first embedded sleeve is embedded in the precast bay window, the second embedded sleeve is embedded in the precast composite slab, a first pull ring is connected to the first embedded sleeve, a second pull ring is connected to the second embedded sleeve, and both ends of the pull rod are respectively connected to the first pull ring and the second pull ring through pin shafts.

[0005] In some implementation manners, the pull rod includes a diagonal bracing member, a first internal thread sleeve and a second internal thread sleeve. External threads are provided at both ends of the diagonal bracing member, and one end of the first internal thread sleeve and one end of the second internal thread sleeve are respectively threadedly connected to both ends of the diagonal bracing member; the other end of the first internal thread sleeve and the other end of the second internal thread sleeve are respectively connected to the first pull ring and the second pull ring through pin shafts.

[0006] In some implementation manners, both the first pull ring and the second pull ring are double-ear pull rings.

[0007] In some implementation manners, the first embedded sleeve is fixedly connected to the first pull ring through a first connection assembly. The first connection assembly includes a first connection bolt, a first baffle, a first U-shaped connecting piece, and a first fixing piece. The open end of the first U-shaped connecting piece is fixed on the first baffle. The first connection bolt passes through the first baffle and is threadedly connected to the first embedded sleeve, thereby fixing the first baffle on the precast bay window. The first fixing piece is clamped between the head of the first connection bolt and the first baffle.

[0008] In some implementation manners, the second embedded sleeve is fixedly connected to the second pull ring through a second connection assembly. The second connection assembly includes a second connection bolt, a second baffle, a second U-shaped connecting piece, and a second fixing piece. The open end of the second U-shaped connecting piece is fixed on the second baffle. The second connection bolt passes through the second baffle and is threadedly connected to the second embedded sleeve, thereby fixing the second baffle on the precast bay window. The second fixing piece is clamped between the head of the second connection bolt and the second baffle.

[0009] In some implementation manners, the second embedded sleeve is fixedly connected to the additional steel bars in the precast composite slab.

[0010] To achieve the above-mentioned invention purpose, the present invention also provides a method for installing and fixing a precast bay window by using the above-mentioned installation and fixing device. The method includes the following steps:

[0011] Through the deepening of the design drawings, the embedded positions of the first embedded sleeve and the second embedded sleeve are respectively marked in the precast bay window component drawings and the precast composite slab component drawings. The precast processing factory manufactures the precast bay window and the precast composite slab according to the deepened design drawings.

[0012] Transport the precast components of the standard floor to the construction site. After the hoisting of the precast composite slab and the casting of the shear wall on the current floor are completed and the concrete curing reaches the required strength, hoist the precast bay window on the current floor.

[0013] First, adjust the elevation and check the installation position. Subsequently, install and fix the precast bay window. Connect one end of the pull rod to the first embedded sleeve buried in the precast bay window, and connect the other end of the pull rod to the second embedded sleeve buried in the precast composite slab.

[0014] Then, tighten the pull rod by adjusting the pull rod to firmly tie the precast bay window and the precast composite slab into a whole, thus completing the installation and fixing of the precast bay window.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

Moreover, both the pull rod and the pull ring can be disassembled and reused after the construction of this layer is completed, reducing the cost of fixing the precast bay window and greatly reducing the workload of manually cutting off the embedded pull ring in the later stage.
