Description

Technical Field

[0001] This utility model relates to the field of ALC wall panel construction technology, specifically to an ALC wall panel grouting anti-crack structure. Background Technology

[0002] With social development, the construction industry is moving towards industrialization and greening, and the application of ALC panels is rapidly entering the construction industry. Currently, the main processes for installing ALC panels include: laying out lines and marking lines, installing U-shaped clips, positioning the panels, adjusting verticality, filling the joints with grout, applying mesh, and repair and maintenance. However, ALC wall panels may crack with the top concrete structure due to settlement, shrinkage, etc., reducing the connection strength between the ALC wall panels and the concrete structure. This can easily lead to cracking of the putty or latex paint on the surface of the ALC wall panels when exposed to vibration or impact.

[0003] The existing solution involves installing single-pipe clamps between the ALC wall panel and the top concrete structure, with each clamp connecting to both. However, this method results in relatively low connection strength for the single-pipe clamps, and cracks that develop between the ALC wall panel and the top concrete structure cannot be effectively filled. Utility Model Content

[0004] In view of this, the present invention provides an ALC wall panel grouting anti-crack structure to solve the problems of low connection strength between ALC wall panel and top concrete and inability to effectively fill cracks in the prior art.

[0005] This utility model provides an ALC wall panel grouting crack-resistant structure, which is installed between the ALC wall panel and the concrete structure located at the top of the ALC wall panel. The ALC wall panel includes multiple ALC strips arranged in sequence, including: Grouting grooves are located at the top of the ALC strip and are arranged along the extension direction of the ALC wall panel. Grouting pipes are laid in the grouting trench. The grouting pipes have several overflow holes in their body and are adapted to grout the grouting trench through the overflow holes. A loop-shaped double-pipe clamp is installed across the grouting groove and connected to the ALC strip and the concrete structure respectively. The ALC strips are installed and grouting is performed through the grouting pipe after a preset time, so that the ALC strips settle before grouting.

[0006] In this application, by laying grouting pipes within a grouting trench and providing overflow holes, grout can fill the cracks between the ALC panel and the concrete structure during grouting. A double-pipe clamp spans the grouting trench and is anchored to both the ALC panel and the top concrete structure, forming a rigid connection that enhances the bond strength between the ALC panel and the concrete structure, thus providing vertical stability to the ALC panel. Grouting is performed after the ALC panel installation is completed and a preset time has elapsed, ensuring that the ALC panel's own settlement is largely complete and preventing the filling layer formed by grouting before the structure is stable from failing due to subsequent settlement. This application can effectively fill cracks that arise after settlement, even from the inside of the cracks. In one alternative embodiment, the end of the grouting pipe extends to the outside of the ALC strip between two adjacent ALC strips.

[0007] In this application, a single grouting pipe can span one or more ALC panels, serving a continuous grouting section. When the grouting pipe extends from the grouting groove of one panel to the grouting groove of an adjacent panel and protrudes from the panel end, grouting can be performed from the end of the grouting pipe. Cement grout flows through the interior of the grouting pipe and then flows into the grouting groove through the overflow hole, thereby grouting the grouting groove and cracks, completing the grouting and filling of cracks between the ALC panel and the top concrete structure.

[0008] In one alternative embodiment, the grouting pipe is a flexible hose.

[0009] In this application, the flexible hose exhibits excellent flexibility, easily adapting to the grouting groove during installation. During the settlement stabilization process after ALC wall panel installation, minor relative displacement or deformation may occur between the ALC panel and the top concrete structure. If a rigid pipe is used, such deformation could cause the grouting pipe to rupture under pressure or detach from the grouting groove, thus rendering it unusable. The flexible hose, however, can absorb this energy through its own deformation, maintaining the integrity of the structure and ensuring unobstructed grouting channels. Furthermore, after grouting is completed, the portion of the hose extending beyond the ALC panel can be trimmed, and the surface of the ALC panel can be treated.

[0010] In one alternative embodiment, the top end of the grouting pipe is not higher than the top surface of the grouting groove.

[0011] In this application, the top of the grouting pipe is limited to not exceeding the top surface of the grouting trench, ensuring that the grouting pipe is completely contained within the boundary of the grouting trench and does not form additional hard protrusions between the ALC strip and the concrete top slab. If the grouting pipe protrudes above the top of the trench and directly presses against the U-shaped double-pipe clamp, it may affect the tight fit between the U-shaped double-pipe clamp and the ALC strip, weakening the connection function of the U-shaped double-pipe clamp; on the other hand, this protruding hard point may locally hinder the uniform flow and distribution of grout in the gap, potentially leading to incomplete filling in that area. Conversely, when the grouting pipe is completely embedded in the trench, space is provided for grout flow, allowing the cement grout to smoothly wrap around the grouting pipe and fill the entire grouting trench and the upper slab top gap.

[0012] In one optional implementation, the loop-shaped double-tube clamp includes: A U-shaped body is straddling the grouting groove; At least two connecting pipes are provided on the U-shaped body, with the pipe body embedded in the ALC strip; Connecting nails, at least two in number, penetrate the loop and are embedded in the concrete structure.

[0013] In this application, the U-shaped body serves as the primary load-bearing frame, spanning the grouting groove and avoiding interference with the grouting channel. At least two connecting pipes are embedded within the ALC strip, and the U-shaped body has anchoring points within the ALC strip. The connecting pipes secure the ALC strip to the U-shaped body, providing pull-out resistance. Simultaneously, at least two connecting nails penetrate the U-shaped body and embed into the concrete structure, anchoring the U-shaped body to the concrete structure. This connects the ALC strip and the concrete structure together.

[0014] In one alternative embodiment, the spiral shape spans between two adjacent ALC strips.

[0015] In this application, the U-shaped body spans between two adjacent ALC strips along the extension direction of the ALC wall and spans over the grouting groove in the extension direction perpendicular to the ALC wall. The ALC strips on both sides of the grouting groove have solid portions of the U-shaped body, and the two adjacent ALC strips have solid portions of the U-shaped body, which makes it convenient to install connecting pipes and connecting nails in the solid portions of the U-shaped body.

[0016] In one alternative embodiment, in the installation direction, the connecting pipe is disposed on the former of the two ALC strips spanned by the U-shaped body, and the connecting nail is disposed on the concrete structure above the latter of the two ALC strips spanned by the U-shaped body.

[0017] In this application, during installation, a loop-shaped double-pipe clamp is placed across the joint between the Nth and N+1th ALC panels. A connecting pipe is positioned on the Nth ALC panel, and connecting nails are placed on the concrete structure above the N+1th ALC panel. This conforms to the construction logic of installing panels one by one and makes the stress path more reasonable. The first ALC panel is connected to the loop-shaped clamp via the connecting pipe, and then the first ALC panel is installed. Before installing subsequent ALC panels, the other end of the loop-shaped clamp is fixed to the concrete structure above it using connecting nails, thus securing the previously installed ALC panels. This operation can be repeated subsequently, allowing space for the installation of connecting nails, ensuring that the entire ALC wall panel is mounted on the concrete structure.

[0018] In one alternative embodiment, the end of the grouting pipe has a grouting port, which is inclined upward.

[0019] In this application, the grouting port is located at the end of the grouting pipe extending out of the ALC strip. The grouting port is tilted upward to ensure that the cement grout does not flow out after the grouting is completed.

[0020] In one alternative implementation, after the ALC strips are installed, the grouting grooves on adjacent ALC strips are connected.

[0021] In this application, the grouting grooves on adjacent ALC panels are interconnected, enabling long-distance, seamless continuous grouting. After installation and connection, the grouting grooves on the top of each individual ALC panel combine to form a continuous channel system running the entire length of the wall. This continuous channel, along with the grouting pipes laid within it, works together to ensure that the expanding cement grout, propelled by pressure, flows freely without obstruction by the panel joint boundaries, filling all voids at the top of the entire ALC wall.

[0022] In one alternative embodiment, the grouting pipe is used to perform grouting with expansive cement grout.

[0023] In this application, expansive cement grout can completely and densely fill cracks. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] The following is combined with Figures 1 to 4 The following describes embodiments of the present invention.

[0029] According to an embodiment of this utility model, a grouting crack-resistant structure for ALC wall panels is provided, which is disposed between the ALC wall panel and the concrete structure 1 located at the top of the ALC wall panel. The ALC wall panel includes a plurality of ALC strips 2 arranged sequentially, such as... Figure 1 and Figure 2 As shown, it includes: Grouting groove 3 is located at the top of the ALC strip 2 and is arranged along the extension direction of the ALC wall panel. Grouting pipe 4 is laid inside the grouting trench 3. The grouting pipe 4 has several overflow holes 5 at its body. The grouting pipe 4 is adapted to grout the grouting trench 3 through the overflow holes 5. The grouting pipe 4 can have three overflow holes 5 at approximately 300mm intervals. The overflow holes 5 are made by the factory and are evenly distributed along the cross-section of the pipe.

[0030] The spiral double-pipe clamp 6 is straddling the grouting groove 3 and is connected to the ALC strip 2 and the concrete structure 1 respectively; the position of the overflow hole 5 should avoid the solid part of the spiral double-pipe clamp 6 to prevent the overflow hole 5 from being blocked.

[0031] After the ALC strip 2 is installed, grouting is carried out through the grouting pipe 4 after a preset time to ensure that the ALC strip 2 has settled before grouting. Specifically, two days after the ALC strip 2 is installed, when the ALC strip 2 has basically settled, grouting can begin through the grouting pipe 4.

[0032] The total length of the grouting pipe 4 can be determined by the installation length of the ALC wall panel, which is generally the length of 6 ALC strips 2, and can be cut to fit special parts.

[0033] In the factory, the ALC strip 2 with grouting groove 3, the grouting pipe 4, and the loop double pipe clamp 6 are processed and manufactured.

[0034] In this application, by laying the grouting pipe 4 within the grouting trench 3 and providing an overflow hole 5, the grout can fill the cracks between the ALC panel 2 and the concrete structure 1 during grouting. A loop-shaped double-pipe clamp 6 spans the grouting trench 3 and is anchored to both the ALC panel 2 and the top concrete structure 1, forming a rigid connection and enhancing the connection strength between the ALC wall panel and the concrete structure 1, thus providing vertical stability to the ALC wall panel. Grouting is performed after the ALC panel 2 has been installed and a preset time has elapsed, ensuring that the ALC panel 2 has settled sufficiently, preventing the filling layer formed by grouting before the structure is stable from failing due to subsequent settlement. This application can effectively fill cracks that occur after settlement, even from the inside of the cracks. In one alternative embodiment, the end of the grouting pipe 4 extends to the outside of the ALC strip 2 between two adjacent ALC strips 2. The ALC strip 2 has a slot at the end of the grouting pipe 4 to allow the grouting pipe 4 to pass through.

[0035] In this application, there can be multiple grouting pipes 4, each spanning one or a group of ALC strips 2 and extending to the outside of the ALC strips 2 between adjacent blocks or groups of ALC strips 2. A group of ALC strips 2 may include multiple ALC strips 2, and the grouting pipe 4 can serve a continuous grouting section. Alternatively, there can be a single grouting pipe 4, extending from the end of the ALC wall panel across all ALC strips 2. When the grouting pipe 4 extends from the grouting groove 3 of one panel to the grouting groove 3 of an adjacent panel and protrudes from the panel end, grouting can be performed from the end of the grouting pipe 4. Cement grout flows through the interior of the grouting pipe 4 and then flows into the grouting groove 3 through the overflow hole 5, thereby grouting the grouting groove 3 and the cracks, completing the grouting and filling of the cracks between the ALC strips 2 and the top concrete structure 1.

[0036] In one alternative embodiment, the grouting pipe 4 is a flexible hose.

[0037] In this application, the flexible hose exhibits excellent flexibility, easily adapting to the grouting groove 3 during installation. During the settlement stabilization process after the ALC wall panel installation, minor relative displacement or deformation may occur between the ALC strip 2 and the top concrete structure 1. If a rigid pipe is used, such deformation may cause the grouting pipe 4 to rupture under pressure or detach from the grouting groove 3, thus rendering it unusable. The flexible hose, however, can absorb this energy through its own deformation, maintaining the integrity of the structure and the unobstructed grouting channel. Furthermore, after grouting is completed, the portion of the hose extending beyond the ALC strip 2 can be trimmed, and the surface of the ALC strip 2 can be treated.

[0038] In one alternative embodiment, the top end of the grouting pipe 4 is not higher than the top surface of the grouting groove 3.

[0039] In this application, the top of the grouting pipe 4 is limited to not exceeding the top surface of the grouting groove 3, ensuring that the grouting pipe 4 is completely contained within the boundary of the grouting groove 3 and does not form an additional hard protrusion between the ALC strip 2 and the concrete top slab. If the grouting pipe 4 protrudes above the top of the groove and directly presses against the U-shaped double pipe clamp 6, it may affect the tight fit between the U-shaped double pipe clamp 6 and the ALC strip 2, weakening the connection function of the U-shaped double pipe clamp 6; on the other hand, this protruding hard point may locally hinder the uniform flow and distribution of grout in the gap, potentially leading to incomplete filling in that area. Conversely, when the grouting pipe 4 is completely embedded in the groove, space is provided for grout flow, allowing the cement grout to smoothly wrap around the grouting pipe 4 and fill the entire grouting groove 3 and the upper slab top gap.

[0040] In one alternative implementation, such as Figure 3 and Figure 4 As shown, the loop-shaped dual-tube clamp 6 includes: The U-shaped body 7 is straddling the grouting groove 3; At least two connecting pipes 8 are provided on the U-shaped body 7, with the pipe body embedded in the ALC strip 2; the connecting pipes 8 can be steel pipes. There can be two of them, connected to the solid part of the U-shaped body 7 and located on both sides of the grouting groove 3.

[0041] At least two connecting nails 9 penetrate the spiral-shaped body 7 and are embedded within the concrete structure 1. The connecting nails 9 may be matching nails.

[0042] In this application, the U-shaped body 7 serves as the main load-bearing frame, spanning the grouting groove 3 to avoid interference with the grouting channel. At least two connecting pipes 8 are embedded inside the ALC panel 2, and the U-shaped body 7 has anchor points inside the ALC panel 2. The ALC panel 2 is fixed to the U-shaped body 7 through the connecting pipes 8, providing pull-out resistance. Simultaneously, at least two connecting nails 9 penetrate the U-shaped body 7 and are embedded in the concrete structure 1, anchoring the U-shaped body 7 to the concrete structure 1. This connects the ALC panel 2 and the concrete structure 1 together. This application optimizes the top pipe clamps of the ALC panel 2, changing the original single pipe clamp connection to a U-shaped double pipe clamp 6 connection, making the top and bottom of the ALC panel 2 more stable and reducing the probability of ALC wall panel swaying.

[0043] It should be noted that the double-pipe clamp 6 can also be set at the bottom of the ALC strip 2, the body of the connecting pipe 8 is embedded in the ALC strip 2, and the connecting nail 9 is embedded in the concrete structure 1, so as to realize the connection and fixation between the ALC strip 2 and the concrete structure 1 below.

[0044] In addition, at the end of the ALC wall panel, the last ALC strip 2 can be used as a finishing plate. After the grouting pipe is laid in the grouting groove, it can be installed without installing the double pipe clamp.

[0045] In one alternative embodiment, the spiral body 7 spans between two adjacent ALC strips 2.

[0046] In this application, the U-shaped body 7 spans between two adjacent ALC strips 2 along the extension direction of the ALC wall and spans on the grouting groove 3 in the extension direction perpendicular to the ALC wall. The ALC strips 2 on both sides of the grouting groove 3 have solid portions of the U-shaped body 7, and the solid portions of the U-shaped body 7 are located at two adjacent ALC strips 2, which facilitates the installation of connecting pipes 8 and connecting nails 9 at the solid portions of the U-shaped body 7.

[0047] In one alternative embodiment, in the installation direction, the connecting pipe 8 is disposed on the front of the two ALC strips 2 spanned by the U-shaped body 7, and the connecting nail 9 is disposed on the concrete structure 1 above the rear of the two ALC strips 2 spanned by the U-shaped body 7.

[0048] In this application, during installation, a loop-shaped double-pipe clamp 6 is placed across the joint between the Nth and N+1th ALC panel 2. A connecting pipe 8 is installed on the Nth ALC panel 2, and a connecting nail 9 is installed on the concrete structure 1 above the N+1th ALC panel 2. This conforms to the construction logic of installing each panel one by one and makes the force path more reasonable. The first ALC panel 2 is connected to the loop-shaped clamp 7 via the connecting pipe 8, and then the first ALC panel 2 is installed. Before the subsequent ALC panel 2 is installed, the other end of the loop-shaped clamp 7 is fixed to the concrete structure 1 above it via the connecting nail 9, thus completing the fastening of the first installed ALC panel 2. This operation is repeated subsequently, leaving room for the installation of the connecting nail 9, so that the entire ALC wall panel is set on the concrete structure 1.

[0049] In one alternative embodiment, the end of the grouting pipe 4 has a grouting port 10, which is inclined upward.

[0050] In this application, the grouting port 10 is located at the port of the grouting pipe 4 extending out of the ALC strip 2. The grouting port 10 is tilted upward to ensure that the cement grout does not flow out after the grouting is completed.

[0051] Specifically, after the grouting of ALC strip 2 is completed, the grouting port 10 is cut off, and the joints of ALC strip 2 are treated. Finally, ALC strip 2 is installed and the surface is smooth and without cracks.

[0052] In one optional embodiment, after the ALC strip 2 is installed, the grouting grooves 3 on adjacent ALC strips 2 are connected.

[0053] In this application, the grouting grooves 3 on adjacent ALC panels 2 are interconnected, enabling long-distance, seamless continuous grouting. After installation and docking, the grouting grooves 3 on the top of each independent ALC panel 2 combine to form a continuous channel system running the entire length of the wall. The continuous channel, together with the grouting pipes 4 laid within it, ensures that the expanding cement grout, under pressure, flows freely without being hindered by the panel joint boundaries and fills all the voids at the top of the entire ALC wall.

[0054] In one alternative embodiment, the grouting pipe 4 uses expanding cement grout for grouting.

[0055] In this application, the expansive cement grout can completely and densely fill the cracks. Specifically, the expansive cement grout can be a micro-expansive cement grout. By injecting the micro-expansive cement grout, the gap between the ALC strip 2 and the concrete structure 1 is filled, thus preventing surface cracking of the ALC strip 2.

[0056] Beneficial effects: 1. This application is basically applicable to all ALC strip 2 installations.

[0057] 2. The top pipe clamps of ALC panel 2 have been optimized, changing the original single pipe clamp connection to a loop-shaped double pipe clamp 6 connection, making the top and bottom of ALC panel 2 more stable and reducing the probability of wall panel shaking.

[0058] 3. A grouting groove 3 is opened above the ALC strip 2 for laying the grouting pipe 4. By adding micro-expansion cement grout, the gap between the ALC strip 2 and the concrete structure 1 is filled to prevent surface cracking. It can effectively resist the stress generated by settlement and shrinkage, avoid cracks, extend the service life of the building, reduce the consumption of later maintenance resources, and its good sealing performance can also improve the building's thermal insulation and sound insulation effects, reduce building energy consumption, and demonstrate green value from the whole life cycle, providing an innovative practice path for the industrialization and green development of the building industry.

[0059] 4. The ALC strip 2 is all processed in the factory, and the grouting groove 3 is also integrally processed and formed in the factory. Factory prefabrication and on-site installation contribute to building industrialization and energy conservation and environmental protection.

[0060] 5. The length of the grouting pipe is fixed and is manufactured by the factory.

[0061] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
