Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and in particular to a prefabricated interior wall panel structure. Background Technology

[0002] The apartment buildings in this project adopt a prefabricated concrete shear wall structure. Prefabricated components are used from the second floor roof slab onwards. The prefabricated components include: prefabricated exterior wall panels, prefabricated interior wall panels, and composite floor slabs.

[0003] Traditional interior partition walls are mostly constructed using masonry blocks or cast-in-place concrete, which have drawbacks such as long construction periods, extensive wet work, and significant environmental pollution. Although existing prefabricated panel walls are prefabricated in factories, there are still many technical challenges during on-site installation.

[0004] First, the reliability of the connection between the panel and the top and bottom panels, especially the fixing of the last panel, has long been a challenge. Conventional methods often fail to effectively constrain the end panel, leading to loosening and affecting the overall stability of the wall. Second, panel installation and leveling mainly rely on workers inserting or hammering wooden wedges under the panels, a process that is inefficient, has poor leveling accuracy, and may cause wall settlement after the wedges are removed. Third, the deformation differences between the panel and the main structure can easily create stress concentrations at joints and corners, leading to a high risk of cracking. Furthermore, existing installation methods lack an effective preliminary positioning system, allowing panels to shift before leveling and fixing, increasing installation difficulty and adjustment time.

[0005] Therefore, there is an urgent need in this field for a prefabricated interior wall panel structure that is easy to install, reliably connected, easy to level, and effectively prevents cracking. Utility Model Content

[0006] The purpose of this utility model is to provide a prefabricated interior wall panel structure to solve the technical problems of weak fixation of end strips, difficulty in overall leveling, and easy cracking during the installation of traditional prefabricated interior wall panels.

[0007] To achieve the above objectives, the present invention adopts the following technical solution.

[0008] A prefabricated interior wall panel structure, set between a top panel and a bottom panel, includes strip panels, a decorative layer, a top fastening system, a bottom positioning system, a bottom filling layer, and a crack-resistant structure;

[0009] The strip has at least two pieces, which are spliced ​​together along the length direction;

[0010] The top fastening system includes a first fastener, a second fastener, and an elastic layer; a set of the first fasteners is disposed above the top joint of adjacent strips except for the last strip; the second fasteners are disposed above the top of the last strip and located on the front and rear sides of the last strip; both the first and second fasteners are fixedly connected to the top plate; the elastic layer is padded in the joint at the top of the strip.

[0011] The bottom positioning system includes a slider fixed to the base plate and a groove formed on the bottom of the strip plate that matches the shape of the slider;

[0012] The bottom filling layer is a fine stone concrete layer that fills the gap between the bottom of the strip and the base plate;

[0013] The crack-resistant structure includes an alkaline mesh fabric laid on the front and back sides of the strip and at the corners of the top plate;

[0014] The decorative layer is disposed on the front and back sides of a set of strips and extends to the bottom surface of the top plate.

[0015] Preferably, the system further includes a leveling system, which includes a leveling bolt and a nut; the leveling bolt is vertically mounted on the base plate, with its upper end close to the bottom of the strip; the nut is screwed onto the leveling bolt and located below the bottom of the strip.

[0016] Preferably, the decorative layer has a multi-layer structure, comprising, from the inside out, a sound insulation layer and a finishing layer bonded to the strip.

[0017] Preferably, the longitudinal section of the first fastener is an inverted U-shape and is connected to the top plate by a first bolt.

[0018] Preferably, there are two second fasteners, which are made of angle steel and are respectively connected to the top plate by second bolts.

[0019] Preferably, the distance between the top of the strip and the top plate, and the distance between the bottom of the strip and the bottom plate are both 10~20mm.

[0020] Preferably, at least one side of a set of strips is provided with a structural wall or structural column, and the outermost strip is bonded to the structural wall or structural column by an adhesive.

[0021] Preferably, the strip is an ALC plate or a hollow strip.

[0022] Compared with the prior art, the present invention has the following features and beneficial effects.

[0023] The connection is firm and the stability is high: By setting a first fastener for the first to the penultimate strip and a second fastener specifically for clamping and fixing the last strip, a differentiated top fixing system is formed, which realizes reliable and loose fixation of all strips, especially the end strip, and greatly improves the overall stability of the wall.

[0024] Quick installation and precise leveling: The bottom positioning system, consisting of sliders and grooves, enables rapid initial positioning and horizontal limiting of the panels. Combined with the bottom leveling system, which consists of leveling bolts and nuts, precise and quantitative fine-tuning of the panel height and verticality is achieved. This process is simple to operate, and the leveling results are stable and reliable, completely avoiding wall settlement problems caused by the use of wooden wedges, and significantly improving installation efficiency and quality.

[0025] Multiple crack-resistant features and superior performance: A multi-layered crack-resistant system is formed. The elastic layer at the top joint effectively buffers vertical deformation stress; the fine aggregate concrete layer at the bottom provides rigid support and seals gaps; and the alkaline mesh fabric laid at the corners of the slabs and the top slab effectively resists surface cracking. The combination of these three features fundamentally inhibits the formation of cracks.

[0026] Functional integration and strong applicability: The decorative layer can adopt a multi-layer structure including a sound insulation layer, which improves the sound insulation performance of the wall while realizing the decorative function. The entire structure is suitable for various materials such as ALC board and hollow strip board, and can be reliably connected to existing structural walls or structural columns, making it widely applicable and highly practical.

[0041] The decorative layer 4 is disposed on the front and rear sides of a set of strips 3 and extends to the bottom surface of the top plate 1.

[0042] In this embodiment, a leveling system is also included, which includes a leveling bolt 10 and a nut 11. The leveling bolt 10 is vertically arranged on the base plate 2, and the upper end of the leveling bolt 10 is close to the bottom of the strip plate 3. The nut 11 is screwed onto the leveling bolt 10 and is located below the bottom of the strip plate 3.

[0043] In this embodiment, the decorative layer 4 has a multi-layer structure, which includes, from the inside out, a sound insulation layer 4a and a decorative layer 4b that are bonded to the strip 3.

[0044] In this embodiment, the longitudinal section of the first fastener 5 is an inverted U-shape, and it is connected to the top plate 1 by the first bolt 13.

[0045] In this embodiment, there are two second fasteners 6. The two second fasteners 6 are made of angle steel and are respectively connected to the top plate 1 by second bolts 14.

[0046] In this embodiment, the distance between the top of the strip 3 and the top plate 1, and the distance between the bottom of the strip 3 and the bottom plate 2 are both 10~20mm.

[0047] In this embodiment, at least one side of a set of strips 3 is provided with a structural wall 12 or a structural column 15, and the outermost strip 3 is bonded to the structural wall 12 or structural column 15 by an adhesive.

[0051] In this embodiment, the leveling component further includes a shim placed between the lower end of the leveling bolt 10 and the base plate 2.

[0052] The middle strip plate of this utility model is operated according to the following steps:

[0053] Measurement and layout: Use a laser level to mark the center line, edge line and installation positioning line of the wall on the top plate 1 and bottom plate 2, and mark the elevation control line of the wall on the adjacent structural wall 12 or structural column 15.

[0054] Installation of the bottom positioning system and leveling system: According to the layout position, firmly fix the slider 16 on the base plate 2, ensuring that the top surface of all sliders 16 is at the same elevation and in an accurate position, so as to ensure that the groove 17 of the strip plate 3 can be smoothly fitted in; at the same time, set the leveling bolt 10 vertically on the base plate 2.

[0055] Installation of the top fastening system: For the first to the second to last strip 3, the first fastener 5 is installed above the top joint of the adjacent strips.

[0056] Apply adhesive: Apply professional adhesive to the joint surface of the structural wall 12 or structural column 15, the side of the installed strip 3, and the top of the strip 3 to be installed to form a loach back-shaped cross section.

[0057] Strip installation and initial positioning: Use hoisting equipment or manual labor to lift the first strip 3, align the sliding groove 17 at the bottom of the strip with the slider 16 already installed on the base plate 2, and slowly lower it so that the strip 3 naturally sits on the slider 16 by gravity. The top of the strip 3 is engaged in the first fastener 5. This bottom positioning system can effectively limit the horizontal displacement of the strip 3 and provide initial support.

[0058] Leveling and precise positioning: Tighten the upper end of the bolt to the bottom of the strip 3, rotate the nut 11 to tighten the nut 11 to the bottom of the strip 3, and use a spirit level or laser level to check the verticality and flatness of the wall.

[0059] When it is necessary to raise the bar: turn the nut 11 clockwise to use the reaction force of the bolt to lift the bar 3.

[0060] When it is necessary to lower the bar: turn the nut 11 counterclockwise to make the bar 3 lower slightly under its own weight.

[0061] Repeat the adjustment of each leveling point until the entire wall meets the specified verticality and flatness requirements. After leveling, tighten all nuts 11 completely.

[0062] Install subsequent strips 3 in sequence, ensuring that adjacent strips are tightly joined.
