Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an ALC composite wall panel. Background Technology

[0002] In railway buildings, signal relay stations, communication base stations, communication repeaters, and signal and communication equipment rooms are dedicated to housing signal and communication low-voltage electrical equipment related to railway transportation. The operation of such equipment directly affects train operation safety. In order to prevent the equipment from being affected by external electromagnetic interference and to ensure stable operation, Faraday cage hexahedral steel mesh is usually installed in the corresponding equipment room to isolate external electromagnetic interference.

[0003] Traditional Faraday cage structures for signal and communication equipment buildings consist of a bottom, a top, and four facades. The bottom and top facades typically have shielding steel mesh placed within the finishing layer, or the structural floor slab reinforcement can be used as shielding steel mesh. The shielding steel mesh on the four facades involves the most work, and must consider its connection to door and window openings, making the process more complex. Whether using traditional masonry walls or prefabricated ALC walls, the shielding steel mesh is installed after the wall structure is completed, and finally, the interior wall surface is sealed with cement mortar. This process is lengthy, labor-intensive, and economically unsustainable.

[0004] In view of this, it is necessary to design an ALC composite wall panel to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an ALC composite wall panel that can effectively improve the bending and shear resistance of the panel itself, and at the same time facilitate quick installation to form a wall with electromagnetic shielding function.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An ALC composite wall panel, comprising:

[0008] plate body;

[0009] A reinforcing steel layer is provided in the slab. The reinforcing steel layer includes a plurality of transverse reinforcing bars spaced apart along the length of the slab and longitudinal reinforcing bars spaced apart along the width of the slab. The transverse and longitudinal reinforcing bars are connected so that the reinforcing steel inside the reinforcing steel layer forms a connected mesh structure.

[0010] The pre-reserved grooves are set at the ends of the transverse and longitudinal reinforcing bars respectively, so that the ends of the reinforcing bars are exposed.

[0011] As a further improvement of this utility model, the length of the transverse reinforcing bar is equal to the width of the plate, and the length of the longitudinal reinforcing bar is equal to the length of the plate.

[0012] As a further improvement of this utility model, multiple transverse steel bars are distributed at equal intervals, and the spacing between adjacent transverse steel bars is less than or equal to 600mm.

[0013] As a further improvement of this utility model, multiple longitudinal steel bars are distributed at equal intervals, and the spacing between adjacent longitudinal steel bars is less than or equal to 600mm.

[0014] As a further improvement of this utility model, the spacing between adjacent longitudinal steel bars is 0.15-0.6mm.

[0015] As a further improvement of this utility model, the longitudinal steel bars and the transverse steel bars are arranged symmetrically along the center of the plate.

[0016] As a further improvement of this utility model, the spacing between the longitudinal reinforcement near the side of the plate and the corresponding side of the plate, as well as the spacing between the transverse reinforcement near the side of the plate and the corresponding side of the plate, are both less than or equal to 0.3 mm.

[0017] As a further improvement of this utility model, the steel reinforcement layer is located at 1 / 3-2 / 3 of the plate thickness.

[0018] As a further improvement of this utility model, the reserved slot is rectangular.

[0019] As a further improvement of this utility model, the diameter of the reinforcing bar is 10-12mm.

[0020] The beneficial effects of this utility model are:

[0021] 1. This utility model facilitates the rapid installation of the ALC composite wall panel by setting multiple horizontally and vertically connected reinforcing bars within the panel body and providing pre-reserved grooves to expose the ends of the reinforcing bars on each side of the panel. The pre-reserved grooves facilitate the welding of reinforcing bars in adjacent panels and also serve as observation ports for observing the assembly of adjacent panels, ensuring the continuity of reinforcing bars in the subsequently assembled wall from the ALC composite wall panel. This allows the ALC composite wall panel to be assembled into a wall with good electrical continuity, meaning that the construction of a wall with electromagnetic shielding function can be quickly completed using the ALC composite wall panel.

[0022] 2. The design of this utility model, which sets multiple horizontally and vertically connected steel bars in the panel, enables the wall assembled from the ALC composite wall panel to have electromagnetic shielding function. On the other hand, it also enhances the panel's shear and bending resistance. Compared with conventional ALC wall panels, the ALC composite wall panel has a higher safety redundancy in all stages of transportation, installation, and use, and can better cope with extreme disasters such as strong winds and earthquakes.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0033] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] Please see Figures 1-4 As shown, this utility model provides an ALC composite wall panel, comprising:

[0035] plate body 10;

[0036] A reinforcing steel layer is provided inside the plate 10. The reinforcing steel layer includes a plurality of transverse reinforcing steel bars 21 spaced apart along the length direction of the plate 10 and longitudinal reinforcing steel bars 22 spaced apart along the width direction of the plate 10. The transverse reinforcing steel bars 21 and the longitudinal reinforcing steel bars 22 are connected so that the reinforcing steel bars inside the reinforcing steel layer form a connected mesh structure.

[0037] The reserved groove 30, and multiple reserved grooves 30 are respectively set at the ends of the transverse steel bar 21 and the longitudinal steel bar 22, so that the ends of the steel bars are exposed.

[0038] Specifically, the length of the transverse reinforcement 21 is equal to the width of the slab 10, and the length of the longitudinal reinforcement 22 is equal to the length of the slab 10, so that when the slab 10 is spliced ​​along the width direction, the transverse reinforcement 21 of adjacent slab 10 can abut against each other, and when the slab 10 is spliced ​​along the length direction, the longitudinal reinforcement 22 of adjacent slab 10 can abut against each other, which facilitates the subsequent welding process between adjacent slab 10.

[0039] Specifically, multiple transverse reinforcing bars 21 are distributed at equal intervals, and the spacing between adjacent transverse reinforcing bars 21 is less than or equal to 600mm.

[0040] Multiple longitudinal reinforcing bars 22 are distributed at equal intervals, and the spacing between adjacent longitudinal reinforcing bars 22 is less than or equal to 600mm; preferably, the spacing between adjacent longitudinal reinforcing bars 22 is 0.15-0.6mm. The vertical reinforcing bars in the ALC composite wall panel are the main load-bearing reinforcing bars. By limiting the spacing between adjacent longitudinal reinforcing bars 22, it is possible to avoid the excessive number of longitudinal reinforcing bars 22 due to the small spacing between adjacent longitudinal reinforcing bars 22, which would occupy too much internal space of the panel 10, affect the distribution of concrete in the ALC composite wall panel and thus affect the relevant performance of the ALC composite wall panel. It is also possible to avoid the electromagnetic shielding effect of the wall assembled by the ALC composite wall panel due to the large spacing.

[0041] Specifically, the longitudinal reinforcing bars 22 are arranged symmetrically along the center of the slab 10. By symmetrically arranging the longitudinal reinforcing bars 22 along the center of the slab 10, when there are two or more longitudinal reinforcing bars 22 in the slab 10, the distance from the longitudinal reinforcing bar 22 near the left side of the slab 10 to the left side of the slab 10 is equal to the distance from the longitudinal reinforcing bar 22 near the right side of the slab 10 to the right side of the slab 10. This facilitates the assembly and use of the ALC composite wall panel and avoids the situation where the distance from the longitudinal reinforcing bar 22 near the side of the slab 10 to that side of the slab 10 is too large, which could lead to an excessively large gap between the two longitudinal reinforcing bars 22 located at the connection point of adjacent slab 10s during subsequent assembly due to mirror symmetrical assembly of the slab 10, thus affecting the subsequent electromagnetic shielding effect.

[0042] For example, the spacing between the longitudinal steel bars 22 near the side of the plate 10 and the corresponding side of the plate 10 is less than or equal to 0.3 mm, so that the spacing between the two longitudinal steel bars 22 at the connection of adjacent plates 10 is less than or equal to 0.6 mm.

[0043] Specifically, the transverse reinforcement 21 is also symmetrically arranged along the center of the slab 10, and the distance between the transverse reinforcement 21 near the side of the slab 10 and the corresponding side of the slab 10 is less than or equal to 0.3mm, so that the distance between the two transverse reinforcements 21 at the connection of adjacent slabs 10 is less than or equal to 0.6mm.

[0044] For example, the reserved slot 30 is rectangular.

[0045] For example, such as Figure 5 As shown, the width of the slab 10 is 900mm, and three longitudinal steel bars 22 are provided inside the slab 10. The spacing between adjacent longitudinal steel bars 22 is 300mm, and the spacing between the longitudinal steel bars 22 near the side of the slab 10 and the corresponding side of the slab 10 is 150mm. The length of the slab 10 is 3000mm, and five transverse steel bars 21 are provided inside the slab 10. The spacing between adjacent transverse steel bars 21 is 600mm, and the spacing between the transverse steel bars 21 near the side of the slab 10 and the corresponding side of the slab 10 is 300mm.

[0046] Specifically, along the thickness direction of the slab 10, the reinforcing steel layer is located at 1 / 3 to 2 / 3 of the slab 10. For example, the reinforcing steel layer is located at 1 / 2 of the slab 10's thickness. The specific thickness of the slab 10 can be set as needed.

[0047] For example, the length × width × height of the reserved groove 30 is 120mm × 30mm × 50mm, so that both ends of the transverse reinforcing bars 21 and the longitudinal reinforcing bars 22 are exposed outside the plate 10. The reserved groove 30 facilitates the welding of the reinforcing bars of adjacent plates 10, and also serves as an observation port for observing the assembly of adjacent plates 10, ensuring the continuity of the reinforcing bars in the wall subsequently assembled from the ALC composite wall panels. This allows the ALC composite wall panels to be assembled into a wall with good electrical continuity, such as... Figure 6 As shown, Figure 6 The image shows a hexahedral steel mesh structure within a wall assembled using ALC composite wall panels. The amount of steel reinforcement in the mesh structure is for illustrative purposes only. This demonstrates that the ALC composite wall panels can be used to quickly construct walls with electromagnetic shielding capabilities.

[0048] Specifically, the diameter of the reinforcing bars is 10-12mm to avoid the reinforcing layer having a limited effect on enhancing the shear and bending resistance of the slab 10 due to excessively small diameter bars, and to avoid affecting the prefabrication of the ALC composite wall panel and causing waste of reinforcing bars due to excessively large diameter bars. For example, the reinforcing bars are HPB300 round steel with a diameter of 12mm.

[0049] The ALC composite wall panel of this utility model is prefabricated in the factory, and only installation and painting are required on the construction site. Because the steel bars are built in and the panel surface is smooth, the plastering process can be saved, which greatly saves construction time, significantly improves work efficiency, and has obvious economic benefits.

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
