[0002] In recent years, with the increasing demand for efficiency, quality and sustainability in the construction industry, more and more construction sectors are adopting precast concrete components for construction. Generally, precast concrete components are prefabricated in specialized precast component processing plants and then transported to the construction site for installation. Among these processes, leveling, temporary fixing, and connection between the cast-in-place concrete foundation and the precast concrete component are key steps in the installation of precast concrete components.

[0003] The leveling of precast concrete components is usually achieved by using steel plates and wedges to raise them. Precast components are usually welded to the cast-in-place concrete foundation or by secondary pouring of reserved construction joints. In actual construction, the operation is complicated and the installation accuracy of precast concrete components cannot be guaranteed. Therefore, this utility model provides a precast concrete frame installation structure. Utility Model Content

[0046] Please refer to the attached document. Figures 1-5 This document illustrates a precast concrete frame installation structure provided in an embodiment of this application, used for the installation of precast concrete components (specifically, precast concrete frame columns 3). The structure includes: a cast-in-place concrete foundation 1, a precast concrete frame column 3, a first embedded steel bar 2, a threaded leveling assembly 8, a grouting sleeve 4, and a diagonal bracing assembly.

[0047] A first embedded steel bar 2 and a threaded leveling component 8 are pre-embedded in the cast-in-place concrete foundation 1. The top of the first embedded steel bar 2 extends out of the cast-in-place concrete foundation 1, and the extended part of the top of the first embedded steel bar 2 is used to connect the precast concrete frame column 3. The threaded leveling component 8 is located at the top of the cast-in-place concrete foundation 1. The threaded leveling component 8 is used to support the precast concrete frame column 3 and adjust the verticality of the precast concrete frame column 3. A grouting sleeve 4 is set at the bottom of the precast concrete frame column 3. The bottom end of the grouting sleeve 4 corresponds to the top end of the first embedded steel bar 2. The diagonal bracing component is used to stabilize the precast concrete frame column 3 in a vertical state. A grouting port 5 is opened on the side of the grouting sleeve 4 near the bottom end. An exhaust port 6 is opened on the side of the grouting sleeve 4 near the top end. Generally, there are also reserved notches on the precast concrete frame column 3 corresponding to the grouting port 5 and the exhaust port 6 to prevent concrete from blocking the grouting port 5 and the exhaust port 6.

[0048] In actual construction, the precast concrete frame columns 3 and grouting sleeves 4 are prefabricated in the factory, and the cast-in-place concrete foundation 1 is poured on site. The first embedded steel bars 2 and threaded leveling components 8 are pre-embedded. The first embedded steel bars 2 and threaded leveling components 8 can be installed according to the following... Figure 2The design and distribution are as shown in the diagram. During installation, the precast concrete frame column 3 is hoisted into place using hoisting equipment. After the grouting sleeve 4 is aligned with the top of the first embedded steel bar 2, the precast concrete frame column 3 is lowered. The grouting sleeve 4 is fitted onto the outside of the first embedded steel bar 2, and the threaded leveling component 8 is supported at the bottom of the precast concrete frame column 3. After the precast concrete frame column 3 is lowered into place, the verticality of the precast concrete frame column 3 is measured. The verticality of the precast concrete frame column 3 is adjusted by the threaded leveling component 8. Then, the diagonal bracing component is installed for assistance to prevent the precast concrete frame column 3 from tilting and collapsing before it is fixed.

[0049] High-strength concrete grout is injected into the grouting sleeve 4 through the grouting port 5. The concrete grout solidifies inside the grouting port 5, thus connecting the first embedded steel bar 2 with the precast concrete frame column 3. Subsequently, concrete is filled to seal the gap. After complete solidification, the diagonal bracing assembly is disassembled. The diagonal bracing assembly can be reused.

[0050] In one implementation, in order to prevent the top of the threaded leveling component 8 from damaging the bottom of the precast concrete frame column 3 during the leveling process, a steel plate embedded part 7 corresponding to the threaded leveling component 8 is fixedly installed at the bottom of the precast concrete frame column 3. In actual use, the top of the threaded leveling component 8 rests against the steel plate embedded part 7 to prevent the concrete from being squeezed and damaged.

[0051] In one implementation, the steel plate embedded part 7 specifically includes a steel frame 701 embedded inside the precast concrete frame column 3, and a thickened steel plate 702 is fixedly connected to the bottom end of the steel frame 701.

[0052] The thickened steel plate 702 is welded and fixed together with the steel frame 701. The steel frame 701 is designed in advance during the manufacturing process of the precast concrete frame column 3. When the concrete solidifies, the steel frame 701 is fixed to the precast concrete frame column 3.

[0053] In one implementation, the threaded leveling assembly 8 includes: a first internal threaded embedded part 801 pre-embedded inside the cast-in-place concrete foundation 1, and a leveling screw 802 threadedly connected to the top of the first internal threaded embedded part 801.

[0054] By rotating the leveling screw 802, the leveling screw 802 engages with the first internal threaded embedded part 801, thereby enabling the leveling screw 802 to move up and down. The top of the leveling screw 802 supports the bottom of the precast concrete frame column 3, thereby leveling the bottom surface of the precast concrete frame column 3 (which can also be understood as adjusting the side of the precast concrete frame column 3 to a vertical state).

[0055] In one implementation, a second embedded steel bar is installed inside the precast concrete frame column 3. The bottom end of the second embedded steel bar is inserted into the grouting sleeve 4, and the second embedded steel bar is fixedly connected to the top end of the grouting sleeve 4.

[0056] This allows the second embedded steel bar to be connected to the first embedded steel bar 2 via concrete, ensuring the structural stability of the precast concrete frame column 3 after installation.

[0057] In one implementation, the inner side of the grouting sleeve 4 is provided with an inner protrusion, which can be plate-shaped, ring-shaped, etc., to increase the tightness of the bond between the inner wall of the grouting sleeve 4 and the concrete.

[0058] In an implementation, such as Figure 1 As shown, the diagonal bracing assembly includes: a first connector 9, a second connector 10, and a third connector 11, which are fixedly installed on the side of the precast concrete frame column 3. A second strut 13 is connected between the first connector 9 and the third connector 11, and a first strut 12 is connected between the second connector 10 and the third connector 11. The first connector 9 is located above the center of gravity of the precast concrete frame column 3, and the second connector 10 is located below the center of gravity of the precast concrete frame column 3.

[0059] In practical use, multiple sets of diagonal bracing components can be designed on the side of the precast concrete frame column 3, such as three sets, four sets, eight sets, etc., to ensure that the precast concrete frame column 3 is in a vertical state.

[0060] The design of the first connector 9, the second connector 10, and the third connector 11 is the same. The third connector 11 is described in detail below. It includes a second internal thread embedded part 1101 and a connecting ear 1103, which are fixedly connected by a pre-embedded method. The connecting ear 1103 is fixedly connected to the second internal thread embedded part 1101 by a mounting screw 1102.

[0061] In one implementation, the lengths of the first support rod 12 and the second support rod 13 are adjustable, making them suitable for various practical application scenarios and making the installation of the first support rod 12 and the second support rod 13 more convenient.

[0062] The first support rod 12 and the second support rod 13 have similar structures. The structure of the first support rod 12 is described in detail below. It includes: a rod frame 1201, a connecting hole 1204 at the first end of the rod frame 1201, and a vertical plate 1202 fixedly connected to the second end of the rod frame 1201. There are two sets of rod frames 1201, and threaded rods 1203 are fixedly connected between the vertical plates 1202 corresponding to the two sets of rod frames 1201.

[0063] The overall length of the first support rod 12 is adjusted by adjusting the length of the threaded rod 1203 located between the upright plates 1202 corresponding to the two sets of rods 1201.
