Description

Technical Field

[0001] This invention relates to the field of exterior wall decoration and construction technology, and in particular to an exterior wall brick construction method and tools. Background Technology

[0002] During the construction of university campuses, the requirements for the construction quality and appearance of building facades are even higher. A high-quality, aesthetically pleasing building serves as a calling card for a high-quality campus, which can greatly promote student recruitment and thus bring positive feedback to the school's operations.

[0003] The exterior facade of this project consists entirely of small exterior wall bricks. The building's overall shape is complex, and the brick dimensions are relatively uniform, presenting challenges such as difficulty in positioning, high precision requirements, and complex construction. Using conventional methods would significantly compromise the facade's aesthetic appeal and severely impact project quality. Therefore, after repeated analysis, discussion, and evaluation, the project decided to adopt a novel construction technique to gradually resolve the numerous difficulties encountered during construction. Due to the limited availability of innovative applications of exterior wall bricks, only a few relevant documents were available for reference, and successful case studies were scarce. Summary of the Invention

[0004] The purpose of this invention is to provide a method for constructing exterior wall bricks and related tools, focusing on solving the technical problems of high positioning difficulty, high precision requirements, high operational difficulty for complex shapes, and low efficiency of technical verification.

[0005] The solution to the technical problem of this invention is: to adopt an exterior wall brick construction method, including the following steps: Step 1, modeling and layout: based on the location and shape of each building, an exterior facade model is established. The model reflects the scope, layout and effect of the exterior wall brick pasting. After the model is established, the model is further refined, and detailed drawings of the exterior wall brick pasting in complex shapes are drawn. The model and complex structural layout are combined to ensure the accuracy of the exterior wall brick construction.

[0006] Step 2, Base Treatment: Before the exterior wall tile installation, use a gantry grinding tool to treat the base in the following three aspects: 1) Grind the base to ensure its verticality and flatness, and the straightness of lines in windows and special areas; 2) Ensure the base is clean and free of dust and other debris that may affect the adhesion of the exterior wall tiles; 3) To avoid efflorescence caused by incomplete drying of the base, which could lead to the exterior wall tiles falling off, apply a water-based interface agent to the base surface using a gantry brush before adhering the exterior wall tiles.

[0007] Step 3, Measurement and Layout: After the base layer is cleaned, a comprehensive and systematic layout of the exterior walls can be carried out.

[0008] Step 4, Exterior Wall Tile Installation: After the layout is completed, use a gantry brush tool to install the exterior wall tiles. Before installation, first stir the adhesive for the exterior wall tiles. The stirring time of the electric mixer should not be less than 15 minutes. The adhesive should be used immediately after mixing. Cut the exterior wall tiles according to the exterior wall layout drawing. After cutting, use a gantry load-bearing tool to install the exterior wall tiles. When installing, ensure that the tile joint width, tile joint depth, straightness of the inside and outside corners of the exterior wall tiles, and flatness and verticality of the exterior wall tiles meet the requirements.

[0009] Step 5, Technical Verification: Using a convex ruler, tape measure, leveling instrument, and straightedge, measure the width and depth of the brick joints, the straightness of the brick joints, the flatness and verticality of the exterior wall bricks. Focus on controlling the error of the brick joint width and depth to be within 1mm, the error of the brick joint straightness to be within 1mm, and the error of the verticality and flatness of the exterior wall bricks to be within 3mm.

[0010] Step 6, Pull-out test: After the technical verification of the exterior wall bricks is completed, a pull-out test is conducted on the exterior wall bricks according to the specifications and construction drawings. Only after the pull-out test data is qualified can the next step be carried out.

[0011] Step 7: Grouting of exterior wall tiles: After the exterior wall tiles are installed and all quality standards are met, grouting of the exterior wall tiles is carried out.

[0012] Preferably, step 3 includes the following: 1) Vertical lines should be set along the entire height of the building at the windows and corners of the exterior walls, with a spacing of no more than 1m between the vertical lines, to ensure that the straightness and verticality of the building facade, especially the complex shapes, are controllable; 2) The floor ring closed elevation control line is measured to strictly control the elevation closure of individual buildings and ensure that the elevation of individual buildings is consistent; 3) In the area where the exterior wall bricks are pasted, horizontal and vertical control lines are hung at intervals of two bricks every two layers, based on the vertical line and elevation control line. The brick joints of the exterior wall bricks are finely adjusted within the allowable error range according to the actual conditions of the project.

[0013] Preferably, in step 4, during the construction of exterior wall tiles, custom molds are used to assist in the construction of complex parts. After the drawings are refined, custom molds are made and placed directly on the site. In order to prevent the exterior wall tiles from slipping during the pasting process, correction is required 30 to 60 minutes after the exterior wall tiles are pasted to avoid unevenness in the tile joints.

[0014] Preferably, in step 5, the convex ruler measuring tool includes a steel ruler body with a narrowed insertion part at one end. Both the steel ruler body and the insertion part are provided with graduations. The convex ruler measuring tool simultaneously measures the width and depth of the brick joint. This measuring tool is made of a steel ruler and, after design and processing, can be used to measure the width and depth of the brick joint. If the width and depth of the brick joint in the exterior wall meet the requirements, the insertion part of the convex ruler measuring tool can be smoothly inserted into the brick joint in the exterior wall; otherwise, the following situation occurs:

[0015] 1) If the width of the brick joints in the exterior wall is large, there will be a gap after the insertion part is placed into the brick joints in the exterior wall;

[0016] 2) If the width of the brick joints in the exterior wall is small, the insertion part cannot be placed into the brick joints in the exterior wall;

[0017] 3) If the depth of the brick joints in the exterior wall is small, the insertion part cannot be fully inserted into the brick joints in the depth direction.

[0018] 4) If the depth of the brick joints in the exterior wall is large, the insert can be moved in the direction of the brick joint after being inserted into the brick joint.

[0019] Preferably, the grouting process in step 7 is as follows: 1) Mix the grout with water using a mixing tool for at least 15 minutes; 2) Fill the mixed grout into the grouting tool and grout the joints, ensuring that the joints are fully filled without contaminating the exterior wall tiles; 3) After the grout has dried for several hours, use a tool to smooth the grout in the joints, ensuring that the joints are flat and concave after grouting. The deepest joint after grouting should be 7mm, and the joints should be smooth, straight, and full, with no grout contamination on the exterior wall tiles.

[0020] A gantry-type load-bearing tool applied to exterior wall brick construction includes a fixed base, a fixed rail, sleeves, column heads, extension columns, sliding sleeves, a crossbeam, a slider, and an adjusting seat. The fixed rail is laterally fixed to the top of the wall. A track groove is provided on the rear side of the fixed base, allowing the fixed base to move laterally along the fixed rail. A locking pin is installed on the fixed base to lock it to the fixed rail. Sleeves are fixed at both ends of the fixed base. A column head is vertically fixed below each sleeve, and a crossbeam assembly is fitted onto the column head. An extension column, with the same diameter as the column head, is connected below each column head, allowing the crossbeam assembly to move downwards along the column head to the outside of the extension column. The crossbeam assembly includes a crossbeam and sliding sleeves at both ends, each sliding sleeve fitting onto the outside of the corresponding column head or extension column. A locking mechanism is provided on the outside of the sliding sleeves. A slider is fitted onto the outside of the crossbeam, and an adjusting seat is installed on the slider.

[0021] Preferably, a grinding mechanism is fixed on the upper side of the adjustment seat of the gantry bearing tool, and a grinding head is installed on the rotating shaft end of the grinding mechanism to form a gantry grinding tool.

[0022] Preferably, a material box is installed on the adjusting seat of the gantry bearing tool. The upper end of the material box has a hopper, and the inner end of the material box has an output port. Shaft brackets are set on both sides of the output port and roller brushes are installed. The output port is connected to the side of the roller brush to form a gantry coating tool.

[0023] Preferably, the gantry crane includes a lifting drive mechanism.

[0024] Preferably, the sleeve rod is inserted into the inner cavity at both ends of the fixing seat, and the sleeve rod at both ends is fixed by the locking pin.

[0025] This invention's method for constructing exterior wall bricks overcomes technical challenges such as difficult positioning, high precision requirements, complex shape operation difficulties, and low efficiency in technical verification. It offers the following advantages: 1. The exterior facade is modeled in advance, and the complex shape is further refined based on the model, combining overall and detailed layout to visually represent the campus facade. 2. Lines are laid out across the entire vertical and horizontal direction of the building facade according to the brick joint arrangement. The brickwork layout is adjusted by modifying the control lines to ensure the quality of the exterior wall bricks meets standards. 3. Innovative measuring tools are used to verify key data such as the width and depth of the brick joints. Through robust quality process control, the positioning of each exterior wall brick and the quality standards for brick joints are properly controlled. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0034] Example 1: A method for constructing exterior wall bricks, comprising the following steps.

[0035] 1. Modeling and Layout: This project is for a school, covering functional buildings including teaching buildings, dormitories, canteens, and activity centers. The facades are complex. Based on the location and shape of each building, a facade model of the campus was created. The model can specifically show the scope, layout, and effect of the exterior wall brickwork. After the model was completed, it was further refined, and detailed drawings of the exterior wall brickwork in complex areas were drawn. The model and the complex structural layout were combined to ensure the accuracy of the exterior wall brickwork construction.

[0036] 2. Base treatment: Before the construction of exterior wall tiles, the base is treated using a gantry grinding tool. Base treatment is crucial and mainly consists of the following three points: 1) Ensure the verticality and flatness of the base, and the straightness of the lines of windows and special parts; 2) Ensure the cleanliness of the base, ensuring that the base surface is free of dust and other debris, which will affect the adhesion of the exterior wall tiles; 3) In order to avoid the plaster base from efflorescence and the exterior wall tiles from falling off naturally due to the base not being completely dry, a water-based interface agent is applied to the base surface using a gantry brush before the exterior wall tiles are adhered.

[0037] 3. Measurement and Layout: After the base layer is cleaned, a comprehensive and systematic layout of the exterior walls can be carried out. 1) For special shapes such as windows and external corners on the exterior walls, plumb lines need to be set along the entire height of the building, with a spacing of no more than 1m, to ensure that the straightness, verticality, and other quality indicators of the building facade, especially complex shapes, are controllable; 2) The floor-level circular closed elevation control lines are established. Because the single-story area of ​​buildings in the campus is large and there are multiple expansion joints, the elevation closure of individual buildings needs to be strictly controlled to ensure that the elevation of individual buildings is consistent; 3) In the area where exterior wall bricks are pasted, based on the vertical line and elevation control line, horizontal and vertical control lines are hung at intervals of 2 courses and 2 bricks (horizontal direction, two bricks constitute one grid (including mortar joints)). According to the actual conditions of the project, the brick joints of the exterior wall bricks are finely adjusted within the allowable error range to better reflect the effect of the exterior wall bricks.

[0038] 4. Exterior Wall Tile Installation: After the base layer treatment and layout are completed, exterior wall tiles are installed using a gantry brush tool. The adhesive for the exterior wall tiles is stirred; the stirring time with an electric mixer should be no less than 15 minutes. The adhesive should be used immediately after mixing and used within 4 hours. The exterior wall tiles are cut according to the exterior wall layout drawing. After cutting, the exterior wall tiles are installed using a gantry bearing tool. During installation, ensure that the tile joint width, joint depth, straightness of the internal and external corners, flatness, and verticality of the exterior wall tiles meet the requirements. For complex areas such as curved sections, custom molds are used to assist in construction. Custom molds are made after the drawings are finalized and placed directly on the site for more precise positioning. To prevent slippage during installation, corrections should be made 30-60 minutes after installation to avoid uneven tile joints.

[0039] 5. Technical verification: Innovative measuring tools, tape measure, leveling instrument, and straightedge are used to measure the width and depth of the brick joints, the straightness of the brick joints, the flatness and verticality of the exterior wall bricks. The key control is to keep the error of the brick joint width and depth within 1mm, the error of the brick joint straightness within 1mm, and the error of the verticality and flatness of the exterior wall bricks within 3mm.

[0040] This innovative measuring tool can simultaneously measure the width and depth of brick joints. Made from a steel ruler, it is designed and manufactured to measure both width and depth. Details are as follows.

[0041] The technical measures are as follows: If the width and depth of the brick joints in the exterior wall meet the requirements, the end of this measuring tool can be smoothly inserted into the brick joints in the exterior wall.

[0042] 1) If the width of the brick joints in the exterior wall is large, there will be a gap after this end is inserted into the brick joints in the exterior wall;

[0043] 2) If the width of the brick joints in the exterior wall is small, this end cannot be inserted into the brick joints in the exterior wall;

[0044] 3) If the depth of the brick joints in the exterior wall is small, then this end (depth direction) cannot be completely inserted into the brick joints in the exterior wall;

[0045] 4) If the depth of the brick joints in the exterior wall is large, this end can be moved in the direction of the brick joint after being inserted into the brick joint.

[0046] Using this innovative measurement tool can significantly improve the efficiency of technical verification and plays an important role in the construction process.

[0047] 6. Pull-out test: After the technical verification of the exterior wall tiles is completed, the adhesion of the tiles must be carefully controlled to prevent detachment due to insufficient adhesion. A specialized pull-out instrument should be used to conduct a pull-out test on the exterior wall tiles according to the specifications and construction drawings. Only after the pull-out test data is qualified can the next step be carried out.

[0048] 7. Exterior Wall Tile Grouting: After the exterior wall tiles are installed and all quality standards are met, grouting can be carried out. Black special grout is used for grouting. Calculations show that 8 kg of special grout is needed per square meter of exterior wall tile grouting. The grouting process is as follows: 1) Mix the grout with water using a special mixing tool for at least 15 minutes; 2) Fill the mixed grout into the grouting tool and grout the joints, ensuring the joints are fully filled without contaminating the exterior wall tiles; 3) After the grout has dried for 4 hours, use a tool to smooth the grout in the joints, ensuring a smooth and even finish. The deepest grout depth should be 7 mm. The joints should be smooth, straight, and full, with no grout contamination on the exterior wall tiles. 4) After the grouting is completed, since the grouting is in an arc shape, it is impossible to use conventional measuring tools to measure the depth of the grouting joints. We creatively used a car tire depth gauge to measure the depth of the brick joints on the exterior wall, which is convenient and quick.

[0049] The gantry tools used in the above methods are all completed by adding corresponding equipment to the basic gantry load-bearing tools. The gantry load-bearing tools mainly include a fixed base, fixed rail, sleeve rod, column head, extension column, sliding sleeve, crossbeam, slider, and adjusting seat, etc. Figure 1As shown, a fixed rail is horizontally fixed to the top of the wall. A track groove is provided on the rear side of the fixing seat, and the fixing seat is fitted onto the outside of the fixed rail through the track groove, allowing the fixing seat to move laterally along the fixed rail. A locking pin is installed on the fixing seat to lock it to the fixed rail. Sleeves are fixed at both ends of the fixing seat; specifically, the sleeves are inserted into the inner cavities at both ends of the fixing seat and fixed by locking pins. A column head is vertically fixed below each sleeve, and a crossbeam assembly is fitted onto the column head. An extension column is connected below each column head; for example, multiple extension columns can be connected sequentially by threaded joints. A longitudinal threaded sleeve is provided at the end of the lowest extension column, and a longitudinal threaded rod is installed inside the sleeve. A stabilizing plate is fixed to the inner end of the longitudinal threaded rod to support the wall or existing brick surface. The extension column has the same diameter as the column head, allowing the crossbeam assembly to move downwards along the column head to the outside of the extension column.

[0050] The crossbeam assembly includes a crossbeam and sliding sleeves at both ends. Each sliding sleeve is fitted onto the outside of a corresponding column head or extension column. A locking mechanism, such as a locking wheel, is provided on the outside of the sliding sleeve. A slider is fitted onto the outside of the crossbeam, and an adjustment seat is installed on the slider.

[0051] When using the gantry crane, fix the fixed rail to the top of the wall using expansion bolts, install the fixing seat on the fixed rail, with the work area below the fixing seat. Move the fixing seat to the area to be worked on, and lock the fixing seat and fixed rail together using locking pins. Then, take out each extension column from the storage box (or place a separate storage box) and connect them sequentially to the bottom of the column heads on both sides. Then slide the crossbeam assembly down to the bottom of the extension column, thus constructing layer by layer from the bottom up. During each layer of construction, as follows... Figure 3 As shown, the adjusting seat on the upper side of the slider is moved and fixed so that the inner end of the adjusting seat is located at a certain depth in the pre-constructed horizontal brick joint. The adjusting seat supports the upper rotating block. At the same time, the markings on the adjusting seat serve as a reference for the brick placement position. A side auxiliary plate can also be installed on the front side of the adjusting seat to position the front side of the corresponding brick, which facilitates rapid construction.

[0052] like Figure 2 As shown, the gantry grinding tool has a grinding mechanism fixed on the upper side of the adjustment seat of the gantry bearing tool, and a grinding head is installed on the rotating shaft end of the grinding mechanism.

[0053] In addition, the gantry painting tool has a material box installed on the adjusting seat of the gantry bearing tool. The upper end of the material box has a hopper, and the inner end of the material box has an output port. Shaft brackets are set on both sides of the output port and roller brushes are installed thereon. The output port is connected to the side of the roller brush.

[0054] like Figure 2 and Figure 4As shown, the gantry crane includes a lifting drive mechanism with a self-locking function. A steel wire rope is connected to the lower end of the sleeve rod via a traction end. Inside the sliding sleeve body are a guide sleeve, a rope wheel chamber, a gear chamber, and a transmission chamber. The guide sleeve is fitted onto the outside of the extension column. A rope wheel is installed in the rope wheel chamber, and the steel wire rope is wound around the rope wheel. A pair of meshing bevel gears, namely the first bevel gear and the second bevel gear, are installed in the gear chamber. A worm gear is installed in the transmission chamber. The crossbeam contains a cavity, within which a transmission shaft is fitted. Both ends of the transmission shaft extend into the transmission chamber and connect to one end of the worm gear's shaft. The other end of the worm gear's shaft extends into the gear chamber and houses the first bevel gear. The rope wheel's shaft extends into the gear chamber and houses the second bevel gear. The worm gear's shaft extends into the transmission chamber and houses a handwheel. When it is necessary to control the lifting of the crossbeam, rotating one side of the handwheel simultaneously controls the rotation of both rope wheels, thereby controlling the synchronous retraction or extension of the steel wire rope. Because the worm gear has a self-locking function, the pulleys at both ends will not rotate automatically when the handwheel stops rotating.

[0055] The specific embodiments described above are merely illustrative or explanatory of the principles of the present invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the present invention should be included within the protection scope of the present invention.
