Description

Technical Field

[0001] This utility model belongs to the field of concrete wall panel technology, specifically relating to the installation structure of ALC exterior wall panels. Background Technology

[0002] In existing technologies, ALC is short for autoclaved lightweight concrete. ALC wall panels are widely used in modern construction. Due to their advantages of light weight, high joint strength, bending resistance, and crack resistance, ALC wall panels are frequently used in various scenarios. Furthermore, in response to the requirements of modern green construction, ALC wall panels have become a green and environmentally friendly building material due to their industrialized and standardized production advantages, and their material characteristics of being non-radioactive and emitting no harmful gases. However, the connection between existing precast components and ALC wall panels requires methods such as grouting sleeve connection technology, which presents problems such as inconvenient construction, low efficiency, and long construction periods.

[0003] Chinese patent with publication number "CN218148850U" discloses a bolt-connected prefabricated concrete wall panel, which includes a floor slab and a precast concrete wall panel. A precast column is provided on the left side above the floor slab, and a precast concrete wall panel is provided on the right side of the precast column. A beam-slab-column structure is provided above the precast column and the precast concrete wall panel.

[0004] In the aforementioned patent, the concrete wall panels are connected by multiple connecting steel plates and high-strength bolts. However, in actual processing, workers need to drill holes in each concrete wall panel. Furthermore, to ensure the strength of the connection between the concrete wall panels, multiple connection points need to be set. This results in workers needing to drill a large number of bolt holes, leading to a large workload, low construction efficiency, and slow construction progress. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, this utility model provides an installation structure for ALC exterior wall panels, which solves the technical problems of large workload and low construction efficiency caused by the need for bolted steel plate connections when connecting ALC wall panels.

[0006] To achieve the above objectives, the specific technical solution of this utility model is as follows: The installation structure of the ALC exterior wall panel includes a bottom floor slab, concrete flanges, ALC wall panels, beams, slabs, columns, an upper floor slab, and positioning and connecting components. The concrete flanges and beams, slabs, and columns are respectively installed on the bottom floor slab and the upper floor slab. The bottom and top of the ALC wall panel abut against the concrete flanges and beams, slabs, and columns, respectively, and are connected and fixed together by positioning and connecting components. The positioning and connecting components include wall connection components and beam connection components.

[0007] The wall connection assembly includes multiple fixing units. Each fixing unit is arranged sequentially at the bottom of the ALC wall panel and includes pre-embedded connectors, hook bolts, and limit clips.

[0008] The embedded connector is fixed to the concrete flange, and its outer end is threaded with a first nut. The hook bolt is fixed to the ALC wall panel. Both ends of the limiting snap-fit ​​component are respectively engaged with the hook bolt of the embedded connector box.

[0009] The beam connection assembly includes a fastener, a nail, and expansion bolts. The fastener is divided into a positioning part and a connecting part from top to bottom. The connecting part is fitted over the top of the ALC wall panel. The nail is driven in through the side of the connecting part, and its inner end is connected to the ALC wall panel. The positioning part is located on the top edge of the connecting part. The expansion bolt is located on the positioning part, and its outer end is fixedly connected to the beam / slab / column.

[0010] Furthermore, the pre-embedded connector is divided into a main body section and a threaded section. The main body section is pre-embedded within the concrete flange; the threaded section is exposed on one side of the concrete flange. The first nut is threadedly connected to the threaded section.

[0011] Furthermore, the hook bolt has an L-shaped structure, consisting of an inner fixing part and an outer hook head. The fixing part passes through the ALC wall panel, and the outer end is threaded with a second nut. The hook head is exposed on the same side as the threaded end of the pre-embedded connector, and its inner surface is spaced apart from the ALC wall panel. The distance between the inner surface of the hook head and the ALC wall panel is the same as the thickness of the limiting clip.

[0012] Furthermore, the limiting snap-fit ​​component is divided into a central limiting part and two snap-fit ​​parts on both sides. The two snap-fit ​​parts on both sides are respectively provided with a first snap groove that mates with the fixing part of the hook bolt; and a second snap groove that mates with the threaded end of the connector.

[0013] Furthermore, a groove is provided on the bottom edge of the ALC wall panel. The depth of the groove is equal to the sum of the thickness of the hook head of the hook bolt and the thickness of the limiting snap-fit ​​component.

[0014] Furthermore, the depth of the groove is 5mm.

[0015] Furthermore, the socket has an inverted U-shaped structure, divided into a middle connecting section and two downward-extending frame sections. The two frame sections are fitted to the outer facade of the ALC wall panel on both sides. Nail holes are formed on the frame sections.

[0016] Furthermore, the connecting section extends outward to form a reinforcing section. Multiple expansion bolts are respectively installed on the positioning part and the reinforcing section.

[0017] Compared with the prior art, the present invention has the following advantages: This invention involves pre-embedding hook bolts and pre-embedded connectors in the ALC wall panel and the concrete flange, respectively.

[0020] In the description of this utility model, it should be understood that the terms "one end", "the other end", "outer side", "upper side", "inner side", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1As shown, the installation structure of the ALC exterior wall panel includes a ground floor slab 1, a concrete flange 2, an ALC wall panel 3, beams, slabs, and columns 4, an upper floor slab, and positioning and connecting components. The concrete flange 2 is cast on the top surface of the ground floor slab 1; the beams, slabs, and columns 4 are cast on the upper floor slab. The top and bottom of the ALC wall panel 3 are respectively attached to the beams, slabs, and columns 4 and the concrete flange 2, and are connected and fixed together by the positioning and connecting components.

[0023] The positioning and connection components include a wall connection component 5 and a beam connection component 6. The ALC wall panel 3 and the concrete flange 2 are fixedly connected via the wall connection component 5. The beam connection component 6 is fitted over the top of the ALC wall panel 3 to achieve a fixed connection between the ALC wall panel 3 and the beam / column 4.

[0024] Specifically, such as Figure 2 As shown, the wall connection assembly 5 includes multiple fixing units, each equally spaced at the bottom of the ALC wall panel 3, including embedded connectors 7, hook bolts 8, and limiting snap-fit ​​components 9. The embedded connectors 7 and hook bolts 8 are fixed to the concrete flange 2 and the ALC wall panel 3, respectively. The two ends of the limiting snap-fit ​​components 9 engage with the hook bolts 8 and the embedded connectors 7, respectively.

[0025] The pre-embedded connector 7 is divided into a main body section and a threaded section. The main body section is pre-embedded in the concrete flange 2; the threaded section is exposed on one side of the concrete flange 2, and the outer end is threaded with a first nut. The first nut can further limit and fix the limiting connector 9 when it is engaged with the threaded section.

[0026] The hook bolt 8 has an L-shaped structure, consisting of an inner fixing part 8-1 and an outer hook head 8-2. The fixing part 8-1 passes through the ALC wall plate 3. A second nut is threaded onto the fixing part 8-1 to achieve limiting and fixing between the hook bolt 8 and the ALC wall plate 3. The hook head 8-2 is exposed on the same side as the threaded end of the pre-embedded connector 7, and its inner surface is spaced apart from the ALC wall plate 3. The distance between the inner surface of the hook head 8-2 and the ALC wall plate 3 is the same as the thickness of the limiting snap-fit ​​9, allowing the limiting snap-fit ​​9 to be easily engaged during installation.

[0027] like Figure 3 As shown, the limiting snap-fit ​​component 9 is divided into a middle limiting part 9-1 and two snap-fit ​​parts on both sides. The two snap-fit ​​parts on both sides are respectively provided with a first snap groove 9-2 that mates with the fixing part 8-1 of the hook bolt 8, and a second snap groove 9-3 that mates with the threaded end of the connector.

[0028] During actual construction, workers prioritize engaging the threaded section of the limiting connector 9 with the pre-embedded connector 7. The limiting connector 9 is positioned horizontally to facilitate the subsequent installation of the ALC wall panel. The threaded section of the pre-embedded connector 7 passes through the second slot 9-3 on the limiting connector 9, and the relative position of the limiting connector 9 and the pre-embedded connector 7 is locked by tightening the first nut.

[0029] Furthermore, a groove 10 is provided on the bottom edge of the ALC wall panel 3. The depth of the groove 10 is equal to the sum of the thickness of the hook head 8-2 of the hook bolt 8 and the thickness of the limiting snap fastener 9.

[0030] In this embodiment, the depth of the groove 10 is 5mm.

[0031] In some embodiments, the distance between the top of the limiting snap-fit ​​9 and the top of the second slot 9-3 is less than the distance between the threaded end of the connector and the hook head 8-2 of the hook bolt 8. When limiting and fixing the ALC wall panel 3 and the concrete flange 2, the worker can first move the ALC wall panel 3 onto the concrete flange 2. Then, the limiting snap-fit ​​9 is horizontally snapped into the embedded connector 7, and after the snap-fit ​​is completed, it is rotated to a vertical position. The vertically positioned embedded connector 7 moves upward, so that the fixing part 8-1 of the hook bolt 8 can smoothly snap into the embedded connector 7.

[0032] like Figure 4 and 5 As shown, the beam connection assembly 6 includes a clip 11, multiple nails 12, and multiple expansion bolts 13. The clip 11 is divided into a positioning part 11-1 and a connecting part 11-2 from top to bottom. The connecting part 11-2 is fitted over the top of the ALC wall panel 3. Each nail 12 is driven into the connecting part 11-2 through nail holes on its side, with its inner end connected to the ALC wall panel 3, thus securing the clip 11 to the ALC wall panel 3. The positioning part 11-1 is located on the top edge of the connecting part 11-2 and serves a positioning function during the installation of the beam, slab, and column 4. Each expansion bolt 13 is located on the positioning part 11-1, with its outer end fixedly connected to the beam, slab, and column 4.

[0033] In this embodiment, the socket 11-2 has an inverted U-shaped structure, consisting of a middle connecting section and two downward-extending frame sections. When the socket 11-2 is fitted onto the ALC wall panel 3, the two frame sections fit snugly against the outer surfaces of both sides of the ALC wall panel 3. The nail holes 12 are located on the frame sections.

[0034] Furthermore, the connecting section extends outward to form the reinforcing section 11-3. Each expansion bolt 13 is respectively installed on the positioning part 11-1 and the reinforcing section 11-3 to form multi-point fixation for the beam, slab and column 4.

[0035] The assembly and connection process of this utility model is as follows: Workers first secure the pre-embedded connector 7 and hook bolt 8 to the concrete flange 2 and ALC wall panel 3 using pre-embedding methods. Next, the limiting snap-fit ​​9 engages with the threaded section of the pre-embedded connector 7. The limiting snap-fit ​​9 is horizontally positioned to facilitate subsequent ALC wall panel installation. The threaded section of the pre-embedded connector 7 passes through the second slot 9-3 on the limiting snap-fit ​​9, and the relative position of the limiting snap-fit ​​9 and the pre-embedded connector 7 is locked by tightening the first nut. Simultaneously, the decorative snap-fit ​​11 is fitted onto the top of the ALC wall panel 3. The sleeve portion 11-2 of the decorative snap-fit ​​11 fits against the top outer ring of the ALC wall panel 3. Workers then drive the nail 12 through the nail 12 hole on the side of the sleeve portion 11-2, with the inner end connected to the ALC wall panel 3, thus securing the decorative snap-fit ​​11 to the ALC wall panel 3.

[0036] Subsequently, the workers hoisted the ALC wall panel 3 to a position flush with the concrete flange 2, and assembled it by pushing it horizontally, ensuring its top and bottom abutted against the beam, slab, column, and concrete flange, respectively. Next, the workers loosened the first nut on the embedded connector and flipped the limiting clip upwards, aligning its end with the hook bolt. The limiting clip was then pushed upwards. The fixing part 8-1 of the hook bolt 8 installed on the ALC wall panel 3 gradually engaged into the first slot 9-2 of the limiting clip 9. The hook head 8-2 of the hook bolt 8 descended until it was flush with the limiting part 9-1 of the limiting clip 9. Through the cooperation between the hook bolt 8 and the limiting clip 9, the horizontal position of the ALC wall panel 3 was limited.

[0037] Subsequently, the beam, slab, and column 4 were hoisted onto the bracket 11, and their edge positions were defined by the positioning part 11-1. The workers then drove multiple expansion bolts 13 into the positioning part 11-1 and the reinforcing section 11-3 of the bracket 11 to form a multi-point fixation for the beam, slab, and column 4.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
