Description

Technical Field

[0001] This utility model belongs to the field of prefabricated modular wall panel technology, and in particular relates to a pre-embedded system for large composite wall panels. Background Technology

[0002] Traditional embedded systems for monolithic exterior wall panels, when the panels are large, heavy, or installed in complex environments, require special attention. According to the national standard atlas "Precast Concrete Exterior Wall Panels" (08SJ110-208SG333), the exterior wall panels should be designed with specific pre-embedded systems in mind. Figure 1 As shown, the independently stressed embedded systems can lead to uneven stress distribution, and the point support system becomes unstable under stress, making it difficult to provide sufficient support and stability, thus affecting the safety of the integrated exterior wall panel. During processing, threaded sleeves are pre-embedded in the upper part of the inner panel of the integrated composite wall panel, and three load-bearing steel components (left, center, and right) are pre-embedded in the lower part. These are fixed to the wall structure layer through connecting steel components, fixing bolts, and fixing steel components, providing the necessary stress and support for the installation nodes.

[0003] The traditional embedded system of integrated exterior wall panels consists of two parts: an anchoring system and a point support system. They are independently stressed and lack stability, so a more stable embedded system is urgently needed. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a pre-embedded system for large composite wall panels, which has a more balanced overall stress, better stability, and more convenient installation and operation.

[0005] To solve the above problems, this utility model adopts the following technical solution:

[0006] An embedded system for large composite wall panels, pre-embedded within the overall composite wall panel, includes an upper embedded component and a lower embedded component. The upper embedded component includes multiple upward-pulling system force-bearing components, and the lower embedded component includes side embedded steel parts and a middle embedded steel part. Both the side embedded steel parts and the middle embedded steel parts include a construction and installation structure. Multiple threaded steel bar assemblies are welded to the top of the construction and installation structure, and multiple bent threaded steel bars are welded to the bottom of the construction and installation structure. The bottom of the construction and installation structure of the side embedded steel parts has a reserved area for adjusting bolts, and the middle embedded part has a wind-resistant installation sleeve welded to the middle of the construction and installation structure.

[0007] Furthermore, the side embedded steel parts include left embedded steel parts and right embedded steel parts, which are symmetrically arranged on both sides of the middle embedded steel parts. The reserved areas for adjusting bolts are respectively located on the side of the left embedded steel parts and the right embedded steel parts near the middle embedded steel parts.

[0008] Furthermore, the threaded rebar assembly includes a first threaded rebar welded to the top of the construction and installation structure, a second threaded rebar welded to the top of the first threaded rebar, and the second threaded rebar being shorter than the first threaded rebar.

[0009] Furthermore, the construction and installation structure includes mutually perpendicular steel plates, two of which are welded and fixed together, and supporting ribs are welded to the sides of the two steel plates.

[0010] Furthermore, the force-bearing component of the pull-up system includes six built-in threaded sleeves, with each set consisting of two built-in threaded sleeves.

[0011] Furthermore, the integral composite wall panel includes an outer layer, a middle layer, and an inner layer, wherein the inner layer is thicker than the outer layer.

[0012] Furthermore, the upper and lower embedded components are built into the inner page plate, and the middle layer and outer page plate structures remain intact.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model combines the side embedded steel parts of the pre-embedded system at the bottom of the composite wall panel into one, which provides gravity steel parts to resist gravity loads and can realize three-dimensional displacement adjustment. For ultra-large-format exterior wall panels, the overall force is balanced, the stability is better, and the installation operation is more convenient.

[0015] 2. The pre-embedded system on the upper part of the composite wall panel is a wind-resistant steel component that resists wind loads and horizontal seismic loads, and can achieve displacement adjustment in three dimensions.

[0016] 3. The embedded steel parts on both sides of the composite wall panel are equipped with reserved positions for installation adjustment bolts. During the construction and installation of the composite wall panel, adjustment bolts can be installed to adjust the position of the composite wall panel in three dimensions to ensure installation accuracy.

[0017] 4. The construction and installation structure of the embedded steel parts consists of two steel plates and multiple supporting ribs welded together to form a steel plate component. The supporting ribs can enhance the strength of the steel plates, making the installation structure more stable.

[0018] 5. The construction and installation structure of the intermediate embedded steel parts is welded with two wind-resistant installation sleeves to ensure the firmness of the construction and installation, while leaving a certain space for the release of internal stress generated by the installation of the overall composite wall panel.

[0031] In this embodiment, the area of ​​the overall composite wall panel 1 is 12㎡ (standard panel width 2 meters, floor height 6 meters), the distance between the upper pull system force-bearing component 2 and the side is 0.2 meters, the distance between the two pre-embedded sleeves in each group is 0.1 meters, and the distance between the side pre-embedded steel component 3 and the side is 0.29 meters. According to the different dimensions of the overall composite wall panel 1, after calculating the force, the positions of the upper pull system force-bearing component 2 and the side pre-embedded steel component 3 will be adjusted accordingly.

[0032] The upper pull system load-bearing component 2 includes 6 built-in threaded sleeves. Each set consists of 2 built-in threaded sleeves. That is, 6 M20*80 hot-dip galvanized threaded sleeves are pre-embedded on the upper part of the overall composite wall panel 1, with a spacing of 100mm between each set of two, to provide the basic load-bearing component for the installation of the upper pull system.

[0033] like Figure 3As shown, the integral composite wall panel 1 includes an outer panel 101, a middle layer 102, and an inner panel 103. The inner panel is thicker than the outer panel. The upper and lower embedded components are built into the inner panel 103. The middle layer 102 and the outer panel 101 maintain their structural integrity.

[0034] like Figure 4 , Figure 6 As shown, in this embodiment, the side embedded steel part 3 includes a left embedded steel part and a right embedded steel part. The left embedded steel part and the right embedded steel part are symmetrically arranged on both sides of the middle embedded steel part 4.

[0035] The construction and installation structure 5 includes two perpendicular steel plates 501, which are welded together and fixed together. Supporting ribs 502 are welded to the sides of the two steel plates 501. The threaded steel bar assembly 6 includes a first threaded steel bar 601 welded to the top of the construction and installation structure 5, and a second threaded steel bar 602 welded to the top of the first threaded steel bar 601. The second threaded steel bar 602 is shorter than the first threaded steel bar 601. 。

[0036] In this embodiment, the first threaded steel bar 601 is a threaded steel bar with a diameter of Φ10mm and a length of 250mm; the second threaded steel bar 602 is a threaded steel bar with a diameter of Φ10mm lapped and welded, with a length of 50mm; the steel plate 501 is a hot-dip galvanized steel plate with a thickness of 12mm; the supporting rib plate 502 is a hot-dip galvanized rib plate with a thickness of 10mm; and the bent threaded steel bar 7 is a bent threaded steel bar with a diameter of Φ10mm.

[0037] The first threaded steel bar 601 and the second threaded steel bar 602 are lap-welded together. Both the first threaded steel bar 601 and the second threaded steel bar 602 are anchored Φ10 grade III threaded steel bars and are welded and fixed to the construction and installation structure 5 to form an integrated pre-embedded steel component system. This system ensures the overall pre-embedded steel component's firmness while providing load-bearing components for construction and installation. The first threaded steel bar 601 is welded to the top of the horizontal steel plate 501. The first threaded steel bar 601 is divided into four groups, with two first threaded steel bars 601 in each group arranged parallel to each other on both sides of the horizontal steel plate 501. The bent threaded steel bar 7 is welded to the surface of the vertical steel plate 501. Three supporting ribs 502 are spaced between the two steel plates 501 to enhance the strength of the steel plates 501, forming a steel plate component and dividing it into two areas. One area is welded with two bent threaded steel bars 7, and the other area serves as a reserved area 8 for adjusting bolts. During installation, in order to ensure installation accuracy, the overall composite wall panel needs to be adjusted in three dimensions after it is in place to ensure installation accuracy.

[0038] like Figure 5As shown, the intermediate embedded steel component 4 consists of a first threaded steel bar 601 and a second threaded steel bar 602 lapped and welded together. Both the lapped and welded steel bar 601 and the bent threaded steel bar 7 are anchored Φ10 grade III threaded steel bars and are welded and fixed to the construction and installation structure 5, forming an integrated embedded steel component system. This system ensures the overall embedded steel component is secure and provides a load-bearing component for the construction and installation. The first threaded steel bar 601 is welded to the top of the horizontal steel plate 501. The first threaded steel bar 601 is divided into three groups, with two first threaded steel bars 601 in each group arranged parallel to each other on both sides of the horizontal steel plate 501. The bent threaded steel bar 7 is welded to the surface of the vertical steel plate 501. Two supporting ribs 502 are welded to the ends of the two steel plates 501 to enhance the strength of the steel plates 501, forming a steel plate component. Two wind-resistant installation sleeves 9 are welded to both sides of the bent threaded steel bar 7 to ensure the overall embedded structure is secure.

[0039] The main function of this system is to release the stress generated during construction and installation, as well as the stress caused by external temperature differences and wet / dry deformation, providing a small amount of space. During construction and installation, the composite wall panel 1 is hoisted to the designated position, and the middle embedded steel part 4 is temporarily fixed by the connector. The adjustment bolt reserved area 8 of the side embedded steel part 3 is used to install adjustment bolts. The upper pull system load-bearing component 2 is fixed to the surface of the main structure by bolts and connectors. After the composite wall panel is in place, the position of the composite wall panel 1 needs to be adjusted in three dimensions by adjusting the bolts. Multiple sets of threaded sleeves provide the basic load-bearing components for the upper pull system. The lower left, middle and right embedded steel parts form the lower support and fixing system of the composite wall panel. The structure of the side embedded steel part 3 ensures the overall steel part pre-embedded firmness while providing load-bearing components for fixing during construction and installation. The left and right embedded steel parts are reserved positions for installing adjustment bolts. During installation, in order to ensure installation accuracy.
