Description

Technical Field

[0001] This invention relates to the field of construction technology for building exterior wall insulation and decorative panels, specifically to an integrated stone panel anchoring device and its construction method that integrates grouting and grout filling detection. Background Technology

[0002] Existing integrated stone insulation panels generally have a large self-weight. Conventional construction uses a composite process of dry anchoring + grouting at the back of the panel and frame. However, the existing patented rotating anchors (CN107060254B) and external grouting equipment (CN114908972B) both have significant technical defects.

[0003] 1. Anchoring and grouting functions are disconnected: Traditional rotary anchors only have mechanical connection function and no built-in grouting channel; external grouting equipment requires separate pipeline layout, the anchoring components and grouting system are two independent structures, the high-altitude operation process is scattered, the amount of manual operation is large, and the construction efficiency is low.

[0004] 2. Uncontrollable bonding quality: The stone has a large self-weight load, and the bonding area of ​​manual grouting is insufficient, resulting in large-area cavities on the back of the slabs and the formation of hollow areas; under the long-term action of temperature changes and wind loads, the decorative stone is prone to cracking, and in severe cases, the entire slab may fall off, posing a major safety hazard; the existing grouting process cannot directionally reinforce the bonding layer at the stress anchoring points, and the stress concentration problem cannot be solved.

[0005] 3. Lack of intuitive testing methods for grout fullness: Current construction relies solely on the experience of construction personnel to judge the cavity filling status. Hidden parts cannot be visually verified, and corners and tops are prone to grout shortages and hollow areas. It is difficult to detect potential water seepage and detachment in advance.

[0006] 4. Poor cavity sealing: Traditional boards lack a perimeter sealing structure, resulting in a large amount of mortar overflowing during the grouting process, high material loss, a large workload for cleaning wall pollution, and the inability to maintain stable grouting pressure, leading to insufficient density of the adhesive layer.

[0007] Existing technologies lack a device that integrates the three major functions of mechanical anchoring, fixed-point grouting, and visual detection of grout filling. This makes it impossible to achieve simultaneous grouting upon anchoring and automatic grout saturation alerts, and it is difficult to fundamentally solve common industry pain points such as hollowing, detachment, and difficulty in construction management of integrated stone panels. Summary of the Invention

[0008] The purpose of this invention is to provide an integrated stone panel anchoring device and its construction method that integrates grouting and grout filling detection, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: an integrated stone panel anchoring device integrating grouting and grout filling detection, comprising a base layer, an angle steel bracket, an integrated stone panel, a grouting anchoring component, and a grout filling detection device; the angle steel bracket is fixedly installed at the lower part of the base layer to support the vertical load of the integrated stone panel; the integrated stone panel is integrally formed by a stone layer, an insulation layer, an isolation plate, and an annular sealing ring; the stone layer has a tongue-and-groove structure on all four sides, the isolation plate has uniformly opened through-diffusion hollow holes, and the annular sealing ring covers the outer edge of the isolation plate; after the panel is attached to the wall, it forms a closed grouting cavity with the base layer; the grouting anchoring component includes two sets of symmetrically arranged L-shaped wall fixing parts, an integrated hollow grouting pipe, a stone tongue-and-groove fixing part, a grouting pipe limiting slider, and a locking nut; the L-shaped wall fixing parts are fixedly installed at the lower part of the base layer to support the vertical load of the integrated stone panel; the integrated stone panel is fixedly installed by an angle steel bracket, ... The grouting pipe is attached to the base layer, and a vertical adjustment groove is opened on the surface of the slab. The hollow grouting pipe and the stone tongue and groove fastener are integrally formed. The grouting pipe passes through the annular sealing ring laterally and the end extends into the sealed grouting cavity. The grouting pipe limiting slider is sleeved on the outer wall of the hollow grouting pipe and is locked into the vertical adjustment groove. The grouting pipe is positioned and locked up and down by tightening the nut. The grout filling detection device is detachably assembled on the exposed top of the hollow grouting pipe and includes a grout outlet connecting pipe, a grout storage chamber, a first limiting sleeve, a spring assembly, a telescopic rod, a second limiting sleeve, a limiting block, and a limiting lever. The grout outlet connecting pipe connects the hollow grouting pipe and the grout storage chamber. The spring assembly is vertically arranged inside the grout storage chamber and its bottom end is fixed to the telescopic rod. The second limiting sleeve has an arc-shaped guide groove. The limiting block is fixed to the side wall of the telescopic rod and embedded in the arc-shaped guide groove. The limiting lever is fixed at the top of the telescopic rod.

[0010] Preferably, the stone tongue and groove fastener matches the four-sided tongue and groove structure of the stone layer to achieve lateral positioning of the integrated stone panel; the diffusion hollow holes on the isolation plate are used for all-round diffusion of grouting mortar to form an annular bonding and reinforcement zone around each anchoring point.

[0011] Preferably, the annular sealing ring is made of flexible rubber, and the hollow grouting pipe is tightly fitted and sealed at the insertion position to prevent grouting mortar from leaking from the side and bottom of the plate, and to maintain the airtightness of the grouting cavity and the stability of the grouting pressure.

[0012] Preferably, the arc-shaped guide groove of the second limiting sleeve matches the 90° rotation of the telescopic rod; when the grout in the sealed grouting cavity is saturated and excess grout flows into the grout storage chamber and the spring assembly is compressed downward, the limiting block slides along the arc-shaped guide groove, simultaneously driving the telescopic rod and the top limiting lever to rotate 90°.

[0013] Preferably, the hollow grouting pipe has a through-hole forming a grouting channel, which serves as both a mechanical tensioning component for the plate and a mortar conveying channel.

[0014] Preferably, the length of the adjustable limit lever can be cut and adjusted to change the rotation trigger stroke of the telescopic lever, thus completing the grout filling prompt in advance and saving the amount of bonding mortar.

[0015] The present invention also provides a construction method for the above-mentioned device, specifically including the following steps:

[0016] S1 Base Layer Positioning Construction: Measure and lay out the base layer, mark the installation points of the grouting anchor components, and install 6-8 sets of grouting anchor components per square meter; fix angle steel brackets along the entire length of the bottom of the base layer;

[0017] S2 Anchoring Component Pre-installation: Fix the two sets of L-shaped wall fasteners to the marked points with expansion bolts, insert the limiting slider of the integrated hollow grouting pipe and stone tongue and groove fastener assembly into the vertical long groove, temporarily loosen the locking nut, and retain vertical adjustment margin;

[0018] S3 Stone Integrated Panel Installation and Positioning: Hoist the stone integrated panel, fit the stone layer tongue and groove into the stone tongue and groove fixing piece, let the hollow grouting pipe pass horizontally through the annular sealing ring, and let the bottom of the panel fall on the angle steel bracket; make slight adjustments to the height of the hollow grouting pipe, tighten the locking nut to complete the panel positioning, and the stone integrated panel and the base layer form a sealed grouting cavity. S4 testing device assembly: A grout filling testing device is sealed and installed at the exposed end of the hollow grouting pipe at the top of each integrated stone panel, and the grout outlet connection pipe is connected to the flow channel of the hollow grouting pipe.

[0019] S5 Low-Pressure Grouting: The grouting equipment is connected from the side hollow grouting pipe, and the grouting pressure is controlled at 0.1-0.4MPa to inject polymer-bonded mortar into the sealed cavity; the mortar flows into the cavity along the hollow grouting pipe and is evenly filled through the diffuser holes of the isolation plate; the excess grout after the cavity is saturated flows into the grout storage chamber through the grout outlet connection pipe.

[0020] S6 Filling Judgment Stopping: The grout's own weight continuously compresses the spring assembly, driving the telescopic rod downwards. The limit block slides along the arc-shaped groove of the second limit sleeve, and the limit lever rotates 90° synchronously and fits against the outer surface of the stone layer. This determines that the cavity mortar is completely full, and grouting is immediately stopped.

[0021] S7 Finishing Seal: Remove all grout filling detection devices and seal the exposed ports of the hollow grouting pipes; fill the gaps between the panels with weather-resistant sealant to complete the overall installation of the integrated stone panel.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0023] This integrated component combines anchoring, grouting, and grout self-inspection. The hollow grouting pipe serves both as a tie and grout delivery pipe. The slab, equipped with a sealing ring, forms a closed grouting cavity, with mortar filling the entire area through isolation holes. A purely mechanical detection device uses a grout-driven lever to rotate 90° for intuitive judgment of fullness. Dual-stress design adapts to both new construction and renovation projects, significantly reducing the risks of hollow areas and high-altitude operations. The streamlined process saves materials, facilitates maintenance, and solves the industry-wide problem of cracking and detachment in integrated stone slabs. Attached Figure Description

Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention discloses an integrated stone slab anchoring device that combines grouting and grout filling detection, such as... Figures 1 to 8 As shown, it mainly includes a base layer 1, an angle steel bracket 2, an integrated stone panel 3, a grouting anchoring component 4, and a grout filling detection device 5. The angle steel bracket 2 is fixedly installed at the lower part of the base layer 1 along its entire length. As a supporting component, it bears all the vertical load of the integrated stone panel 3, avoiding the entire weight of the panel being borne by the anchoring component and improving the system's safety reserve.

[0035] like Figure 2 , Figure 3 As shown, the integrated stone panel 3 is integrally formed from a stone layer 301, an insulation layer 302, an isolation plate 303, and an annular sealing ring 304. The stone layer 301 has tongue-and-groove structures processed around its edges to cooperate with the stone tongue-and-groove fastener 403 for lateral positioning of the panel. The isolation plate 303 has several through-holes evenly distributed diffuser holes. The annular sealing ring 304 is made of flexible rubber and is wrapped around the outer periphery of the isolation plate 303. After the integrated stone panel 3 is installed against the base layer 1, the annular sealing ring 304 seals the gaps on the side of the panel, forming a sealed grouting cavity between the integrated stone panel 3 and the base layer 1. The annular sealing ring 304 and the hollow grouting pipe 402 are tightly fitted and sealed, preventing grout from leaking out from the gaps on the side and bottom of the panel, ensuring the airtightness of the grouting cavity and stabilizing the grouting pressure.

[0036] like Figure 4 , Figure 7As shown, the grouting anchoring assembly 4 includes two symmetrically arranged L-shaped wall fasteners 401, an integrated hollow grouting pipe 402, a stone tongue-and-groove fastener 403, a grouting pipe limiting slider 404, and a locking nut 405. The L-shaped wall fastener 401 is fixed to the base wall 1 with expansion bolts, and a vertical adjustment groove is opened on the surface of the L-shaped wall fastener 401. The hollow grouting pipe 402 and the stone tongue-and-groove fastener 403 are integral components formed by injection molding or casting; the hollow grouting pipe 402 passes horizontally through the annular sealing ring 304, and the end of the pipe extends into the sealed grouting cavity; the grouting pipe limiting slider 404 is sleeved and fixed to the outer wall of the hollow grouting pipe 402, and the limiting slider 404 is inserted into the vertical adjustment groove of the L-shaped wall fastener 401 and locked by the locking nut 405, thereby realizing the vertical height adjustment and positioning of the hollow grouting pipe 402. The hollow grouting pipe 402 forms a continuous grouting channel inside, and the component simultaneously serves the dual functions of mechanically binding and fixing the slab and conveying mortar. The stone tongue and groove fastener 403 matches the tongue and groove of the four sides of the stone layer 301, and after being inserted into the tongue and groove, it restrains the horizontal displacement of the integrated stone slab 3. After the grouting mortar enters the cavity through the hollow grouting pipe 402, it diffuses to the surrounding area through the diffusion hollow holes on the isolation plate 303, forming a ring-shaped bonding reinforcement zone around each anchoring point, thereby improving the problem of local stress concentration at the anchoring point.

[0037] like Figure 5 , Figure 6 As shown, the grout filling detection device 5 is detachably assembled on the exposed top of the hollow grouting pipe 402. The grout filling detection device 5 includes a grout outlet connecting pipe 501, a grout storage chamber 502, a first limiting sleeve 503, a spring assembly 504, a telescopic rod 505, a second limiting sleeve 506, a limiting block 507, and a limiting lever 508. The grout outlet connecting pipe 501 connects the grouting channel of the hollow grouting pipe 402 to the internal cavity of the grout storage chamber 502. The spring assembly 504 is vertically arranged and installed inside the grout storage chamber 502, and its lower end is fixedly connected to the telescopic rod 505. An arc-shaped guide groove is opened on the inner wall of the second limiting sleeve 506. The limiting block 507 is fixed to the side wall of the telescopic rod 505 and is embedded in the arc-shaped guide groove. The limiting lever 508 is horizontally fixed to the top of the telescopic rod 505. The stroke of the arc-shaped guide groove matches the 90° rotation of the telescopic rod 505.

[0038] Once the mortar inside the sealed grouting cavity is completely saturated, excess grout flows into the grout storage chamber 502 through the grout outlet connection pipe 501. The grout's own weight pushes the telescopic rod 505 downward and compresses the spring assembly 504. During the downward movement of the telescopic rod 505, the side wall limiting block 507 slides along the arc-shaped guide groove of the second limiting sleeve 506, driving the telescopic rod 505 and the top limiting lever 508 to complete a 90° rotation simultaneously. When the limiting lever 508 rotates to the outer surface of the stone layer 301, the on-site construction personnel can visually identify that the grout inside the cavity is completely filled, and then stop the grouting operation.

[0039] Furthermore, the limit lever 508 can be cut and adjusted in length according to the on-site working conditions, thereby changing the trigger stroke of the telescopic lever 505 rotation. This allows for earlier triggering of the grout filling indicator signal, reducing the amount of bonding mortar injected and saving materials. After grouting is completed, the entire grout filling detection device 5 can be disassembled and reused.

[0040] like Figure 1 , Figure 8 As shown, this embodiment also provides a construction method for the above-mentioned anchoring device. The specific construction steps are as follows:

[0041] Step 1, Base positioning construction: Measure and lay out the base layer 1, mark the installation points of the grouting anchor components 4, and control the layout density by laying 6 to 8 sets of grouting anchor components 4 per square meter; install angle steel brackets 2 along the bottom of the base layer 1.

[0042] Step 2, Anchoring component pre-installation: Use expansion bolts to fix two sets of L-shaped wall fasteners 401 to the marked points on the base layer 1; insert the grouting pipe limiting slider 404 on the combination of integrated hollow grouting pipe 402 and stone tongue and groove fastener 403 into the vertical adjustment slot of the L-shaped wall fastener 401, and temporarily loosen the locking nut 405 to retain the vertical height adjustment margin.

[0043] Step 3, Stone Integrated Panel Installation and Positioning: Hoist the stone integrated panel 3, assemble the tongue and groove joint of the stone layer 301 onto the stone tongue and groove fixing component 403, so that the hollow grouting pipe 402 passes horizontally through the annular sealing ring 304, and the bottom of the stone integrated panel 3 rests on the angle steel bracket 2; make slight adjustments to the installation height of the hollow grouting pipe 402, level the panel, and tighten the locking nut 405 to complete the locking and positioning; at this time, a sealed grouting cavity is formed between the stone integrated panel 3 and the base layer 1.

[0044] Step 4: Assembly of the testing device: Seal and install the grout filling testing device 5 on the exposed top of the hollow grouting pipe 402 at the top of each integrated stone panel 3 to ensure reliable communication between the grout outlet connection pipe 501 and the internal flow channel of the hollow grouting pipe 402.

[0045] Step 5, Low-pressure grouting: Select the hollow grouting pipe 402 on the side as the grouting port, connect the external grouting equipment, control the grouting pressure to maintain at 0.1-0.4MPa, and inject polymer bonding mortar into the sealed grouting cavity; the grouting mortar enters the sealed grouting cavity through the hollow grouting pipe 402, and then evenly fills the entire cavity area through the diffusion hollow hole on the isolation plate 303; after the cavity is filled, the excess grout flows into the grout storage chamber 502 through the grout outlet connection pipe 501.

[0046] Step Six: Filling Determination and Grouting Stoppage: The grout flowing into the grout storage chamber 502 pushes the telescopic rod 505 downward by its own weight, compressing the spring assembly 504; the limiting block 507 slides along the arc-shaped guide groove of the second limiting sleeve 506, causing the telescopic rod 505 and the limiting lever 508 to rotate 90°. The limiting lever 508 is attached to the outer surface of the stone layer 301. When the personnel on site can visually observe that the lever has rotated into place, it can be determined that the cavity mortar is completely full, and the grouting operation should be stopped immediately.

[0047] Step 7, Finishing and Sealing: After the grouting is completed and the mortar has initially set, remove all grout filling detection devices 5. The detection devices can be reused for the construction of the next slab. Seal the exposed ends of the hollow grouting pipe 402. Fill the gaps between the slabs with weather-resistant sealant to complete the overall installation of the stone integrated panel exterior wall.

[0048] This device integrates mechanical anchoring, fixed-point grouting, and visual detection of grout filling into one unit; the hollow grouting pipe simultaneously achieves bonding and grout delivery; a sealed grouting cavity is constructed by relying on an annular sealing ring, and the mortar diffuses through the hollow holes of the isolation plate to achieve full filling of the back panel; adopting a purely mechanical structure, the grouting slurry drives the limit lever to rotate 90°, providing a visual indication of the grouting fullness; the entire system is subjected to dual forces, making it suitable for both new building exterior walls and existing building exterior wall renovation projects; effectively reducing the safety risks of panel hollowing and detachment, simplifying high-altitude operation procedures, reducing mortar consumption, and facilitating later inspection and maintenance, thus solving the industry pain points of hollowing, cracking, and detachment of integrated stone insulation panels.

[0049] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
