Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to mortar laying devices for brick wall construction and their construction methods. Background Technology

[0002] In brick wall construction, the application of mortar in the joints is a crucial step affecting wall quality and construction efficiency. Traditional methods typically involve manual application of mortar using trowels or spatulas for spreading, leveling, and thickness control. This purely manual approach has several drawbacks: firstly, it is inefficient, increasing labor costs and time; secondly, it is difficult to control the mortar thickness evenly, leading to insufficient joint coverage or mortar waste, thus affecting construction quality; and thirdly, it is physically demanding for workers, hindering refined construction management. Therefore, there is an urgent need for a tool that is simple in structure, easy to operate, and can guarantee mortar application quality to solve these problems. Summary of the Invention

[0003] The purpose of this invention is to provide a brick wall masonry mortar spreader and its construction method to solve the technical problems of low efficiency, uneven thickness, and high cost of manual mortar spreading in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A brick wall masonry mortar laying device, comprising:

[0006] A hopper for holding mortar;

[0007] A guide channel connected to the outlet of the hopper is used to guide the flow of mortar;

[0008] A discharge port located at the discharge end of the guide channel is used to lay mortar on the brick surface; and

[0009] The wheels installed on both sides of the mortar spreader are used to enable the mortar spreader to move on the brick wall.

[0010] In some embodiments, the hopper has a V-shaped structure with its two side walls inclined inward to facilitate the mortar to converge towards the discharge port under gravity.

[0011] In some embodiments, the guide channel is a U-shaped channel structure with an arc-shaped or flat bottom and side walls on both sides, which are used to constrain the mortar flow path and prevent mortar from overflowing.

[0012] In some embodiments, the discharge port has a serrated structure with alternating concave and convex surfaces, used to scrape and spread the mortar when the mortar spreader moves.

[0013] In some embodiments, the serration height of the serrated discharge port is adjustable to accommodate construction requirements with different mortar joint thicknesses.

[0014] In some embodiments, the traveling wheels are connected to the ash spreader body via a connecting rod, which is a detachable structure to facilitate the replacement of traveling wheels of different sizes.

[0015] In some embodiments, the diameter of the traveling wheel is matched with the designed thickness of the mortar joint to be constructed. By changing the diameter of the traveling wheel, the gap between the bottom of the hopper and the brick surface is adjusted, thereby controlling the mortar thickness.

[0016] In some embodiments, the hopper and the guide channel are integrally formed or welded together, and the whole is made of lightweight metal material.

[0017] In some embodiments, a troweling tool is also included to assist in pressing down the mortar in the hopper so that the mortar flows smoothly into the guide channel.

[0018] This embodiment also provides a construction method for mortar laying in brick wall construction, including the following steps:

[0019] Step 1: Select the appropriate size of mortar applicator according to the width of the brick wall, and select the appropriate size of running wheels according to the required mortar joint thickness;

[0020] Step 2: Place the mortar spreader on the already constructed brick wall base, aligning the outlet with the end of the brick wall;

[0021] Step 3: Fill the hopper with mortar;

[0022] Step 4: Push the mortar spreader along the brick wall direction, while simultaneously spreading the mortar evenly on the brick surface from the discharge port;

[0023] Step 5: Stop moving when the mortar length reaches the preset value, and then proceed with bricklaying.

[0024] This invention provides a brick wall masonry mortar laying device and its construction method, which has the following beneficial effects:

[0025] 1. Significantly improves construction efficiency and reduces labor costs.

[0026] This invention integrates the traditional manual process of "taking mortar, spreading mortar, and leveling" into a continuous, mechanized operation by setting up a mortar hopper, a guide trough for guiding the mortar, and wheels. During operation, only one loading and uniform pushing are needed to complete the mortar laying, significantly shortening the time for each mortar laying, reducing labor input, and effectively lowering project labor costs. This is the core benefit of this invention, directly solving the technical problems of low efficiency and high cost mentioned in the background art.

[0027] 2. Ensure uniform mortar joints to improve masonry quality.

[0028] This invention constrains the mortar flow path through guide channels and spreads the mortar through the discharge port, enabling the mortar to be laid evenly and continuously on the brick surface. This avoids problems such as inconsistent thickness and discontinuity common in manual operations. The resulting mortar joints exhibit significantly improved fullness and smoothness, ensuring the quality of wall construction and meeting the requirements of refined construction management.

[0029] 3. Simple structure and low processing cost

[0030] The main body of the ash spreader consists of basic components such as hoppers and guide channels. It can be manufactured by welding or integral molding using lightweight steel. It does not require complex machining equipment and precision parts. The manufacturing process is simple and the materials are readily available, so the production cost is low and it is easy to promote and apply.

[0031] 4. Easy to operate and widely adaptable

[0032] By setting the hopper to a V-shaped structure, the material is automatically collected by gravity, which reduces the frequency of manual assistance in feeding and makes the operation more labor-saving.

[0033] The guide channel is designed as a U-shaped channel structure, which effectively constrains the flow direction of mortar, prevents mortar from overflowing and scattering, ensures the neatness of the mortar laying, and also reduces material waste.

[0034] By setting the discharge port to a serrated structure, the scraping and pressing are integrated, and the mortar is automatically spread out when it flows out, eliminating the need for subsequent manual trimming and completing the mortar laying in one step.

[0035] 5. The mortar joint thickness is adjustable and the precision is controllable.

[0036] By making the serrated discharge port height adjustable, the same mortar spreader can meet the diverse requirements of different projects for mortar joint thickness (such as 8mm, 10mm, 12mm, etc.). Construction personnel can quickly adjust the serration height according to design specifications, thereby precisely controlling the mortar thickness, avoiding rework due to inconsistent thickness, and improving construction accuracy and equipment versatility.

[0037] 6. Quick-change wheels for flexible adaptation to different working conditions.

[0038] By setting the walking wheels and connecting rods as a detachable quick-change structure, operators can change the walking wheels in seconds according to site requirements (such as different brick wall widths and different mortar joint thicknesses), without having to carry multiple pieces of equipment, thus improving the flexibility of on-site construction.

[0039] By matching the diameter of the walking wheels with the thickness of the mortar joint, the physical precision control of the mortar thickness is achieved. The operation is simple and intuitive, requiring no complex measurements or adjustments, thus ensuring consistent thickness.

[0040] 7. Lightweight and durable, easy to store and transport

[0041] The hopper and guide trough are designed as a single molded or welded structure, made of lightweight metal materials. This ensures the stability and service life of the overall structure while reducing the weight of the equipment, making it easy for workers to operate with one hand. Meanwhile, the detachable wheels allow the ash spreader to be disassembled and stored, reducing the space required for storage and transportation.

[0042] 8. Highly operable and adaptable to different mortar consistency.

[0043] By configuring a troweling tool, when the mortar has a high consistency or poor fluidity, it can assist in pressing down the mortar to ensure that the mortar flows smoothly into the guide channel, avoiding clogging problems and improving the equipment's adaptability to different mortar mix ratios.

[0044] 9. The construction methods are scientific and standardized, and easy to promote.

[0045] This invention also provides a standardized construction method for use with the mortar spreader, which clarifies the key points of the entire process from equipment selection, installation, filling, pushing to masonry, enabling construction personnel to quickly master the usage method, reducing technical training costs, and facilitating large-scale promotion in the industry.

[0046] 10. Significant overall cost advantages and outstanding economic and social benefits.

[0047] In summary, this invention offers significant advantages in improving efficiency, ensuring quality, reducing material waste, and minimizing labor input. Long-term use can substantially reduce the overall cost of masonry projects. Furthermore, its simple structure and ease of maintenance extend the equipment's lifespan and reduce replacement frequency, demonstrating excellent economic value and promising prospects for widespread application.

[0052] 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.

[0053] Example 1:

[0054] A brick wall masonry mortar spreader includes: a hopper 1 for holding mortar 6; a guide channel 2 connected to the outlet of the hopper 1 for guiding the flow of mortar 6; a discharge port 4 provided at the discharge end of the guide channel 2 for spreading mortar 6 on the brick surface; and traveling wheels 3 installed on both sides of the mortar spreader for enabling the mortar spreader to move on the brick wall.

[0055] To store sufficient mortar 6 and achieve continuous feeding, the hopper 1 is configured as a container structure with a certain volume. The hopper 1 has a discharge port 4 at its bottom, which is connected to the inlet end of a guide trough 2. To ensure that the mortar 6 flows smoothly from the hopper 1 to the mortar-laying position, the guide trough 2 is configured as a hollow channel structure, with its inlet end fixedly connected to or integrally formed with the discharge port 4 of the hopper 1, thus forming a continuous mortar 6 conveying path. A discharge port 4 is provided at the discharge end of the guide trough 2, which is used to finally lay the mortar 6 on the brick surface. To enable the mortar spreader to move smoothly on the brick wall, traveling wheels 3 are installed on both sides of the mortar spreader. The traveling wheels 3 are rotatably connected to the main body of the mortar spreader via axles, allowing the mortar spreader to be pushed along the wall direction.

[0056] The operator loads mortar 6 into hopper 1, then pushes the mortar spreader. Under gravity, mortar 6 flows from hopper 1 through guide channel 2 to outlet 4 and is evenly spread on the brick wall surface. By setting up hopper 1, guide channel 2, outlet 4, and traveling wheels 3, continuous mortar 6 is achieved, greatly improving mortar spreading efficiency and avoiding the unevenness of manual spreading.

[0057] To facilitate the natural flow of mortar 6 towards the discharge port 4 under gravity and reduce mortar 6 residue in the hopper 1, the hopper 1 is designed with a V-shaped structure. Specifically, the two side walls of the hopper 1 are inclined inward, forming a V-shaped cross-section that is wider at the top and narrower at the bottom. In this way, the mortar 6 will automatically slide towards the discharge port 4 at the bottom under gravity, eliminating the need for frequent manual scraping and ensuring continuous material supply.

[0058] To ensure that the mortar 6 does not overflow when flowing in the guide channel 2 and forms a regular strip of mortar, the guide channel 2 is designed as a U-shaped channel structure. The U-shaped guide channel 2 has a bottom and two side walls, which can constrain the flow path of the mortar 6, allowing it to be laid on the brick surface in a straight line, avoiding the mortar 6 from scattering and being wasted, and improving the regularity of the mortar laying.

[0059] To automatically level the mortar 6 and control the thickness and fullness of the mortar joints during the mortar spreading process, the discharge port 4 is designed with an alternating serrated structure. Specifically, the discharge end of the guide channel 2 is machined into a serrated shape. When the mortar spreader moves, the mortar 6 flows out from the grooves between the serrations, while the raised parts of the serrations scrape and press the mortar 6, ensuring that the mortar 6 is evenly spread on the brick surface, forming a mortar joint of uniform thickness. The serrated discharge port 4 design solves the problem of uneven thickness caused by manual leveling.

[0060] To accommodate the specific requirements of different engineering projects regarding mortar joint thickness, the serrated outlet 4 is designed with adjustable serrations. By adjusting the length of the serrations extending beyond the guide groove 2, the flow rate and final thickness of the mortar 6 can be precisely controlled. For example, the serrated outlet 4 consists of two parts: a fixed base and movable serrations.

[0061] The fixed base is located at the bottom of the discharge end of the guide channel 2, and is integrally formed or welded to the guide channel 2. Several guide rails perpendicular to the discharge direction are provided on the fixed base. The guide rails have a T-shaped cross-section and are used to install and guide the movable saw blades to slide up and down. The movable saw blade consists of a row of independent saw blades corresponding to the number of guide rails, or it can be a single piece of multi-toothed comb plate structure. Each saw blade has a T-shaped slider on its back that matches the guide rail, allowing the saw blade to slide up and down along the guide rail.

[0062] The front end of the saw blade is the working tooth surface, which is triangular in shape, and a groove is formed between adjacent saw blades to allow mortar 6 to flow out.

[0063] Each saw blade has an elongated adjustment hole for use with a locking screw to fix its height. The guide rail has a threaded hole for installing the locking screw. The screw passes through the threaded hole and the elongated adjustment hole in sequence. When the screw is tightened, it secures the saw blade to the guide rail.

[0064] When adjusting the mortar thickness, loosen the screws to allow the movable saw blade to slide up and down along the guide rail. Push the saw blade up or down as needed to change the relative distance between the lower edge of the saw tooth protrusion and the brick surface. The lower the lower edge of the saw tooth protrusion, the larger the gap at the discharge port 4, and the thicker the mortar; conversely, the higher the protrusion, the thinner the mortar. After adjustment, tighten the locking mechanism to fix the position of the saw blade.

[0065] When the mortar spreader is working, mortar 6 flows out from the groove between adjacent saw teeth, and the protruding part of the saw teeth scrapes and presses the mortar 6. Since the height of the saw teeth has been adjusted according to the preset thickness, the thickness of the mortar 6 after scraping and pressing is the required mortar joint thickness.

[0066] By setting up a sliding movable sawtooth blade and a locking mechanism, the height of the discharge port 4 can be continuously or progressively adjusted, allowing the same mortar spreader to adapt to various mortar joint thickness requirements without replacing the entire discharge port 4, greatly improving the equipment's versatility and ease of adjustment.

[0067] To facilitate quick replacement of the appropriate size of the traveling wheels 3 according to different brick wall widths and mortar joint thickness requirements, the traveling wheels 3 are connected to the mortar spreader body via connecting rods 5, and the connecting rods 5 are detachable. Specifically, both ends of the connecting rods 5 are connected to the traveling wheels 3, and the connecting rods 5 themselves are fixed to the mortar spreader body by bolts or clips. When it is necessary to replace the traveling wheels 3 with different diameters, only the connecting rods 5 need to be removed for complete replacement, making the operation extremely convenient.

[0068] To achieve precise control of the mortar thickness, the diameter of the traveling wheel 3 is matched to the designed thickness of the mortar joint to be constructed. Its working principle is as follows: as the traveling wheel 3 rolls on the brick wall surface, it supports the entire mortar applicator; the gap between the bottom of the hopper 1 and the brick surface is the mortar thickness. By selecting traveling wheels 3 of different diameters, this gap can be adjusted, thereby controlling the mortar joint thickness. This design solves the problem of inaccurate thickness control based on traditional manual experience.

[0069] The thickness of the mortar joint can be adjusted and controlled by changing the position of the saw blade and replacing the traveling wheel 3. However, the working principle and adjustment dimension of the two are fundamentally different: adjusting the height of the saw-shaped discharge port 4 directly controls the flow rate and scraping thickness of the mortar 6, which is a "fine adjustment" and "forming" of the mortar thickness. It solves the problem of uniformity and fullness of the mortar 6 at the moment of laying. On the other hand, replacing the traveling wheel 3 with one of different diameters changes the relative height between the entire mortar spreader and the brick surface. It is a "coarse adjustment" and "benchmark establishment" of the mortar thickness. It solves the problem of the equipment quickly adapting to different mortar joint thickness standards and wall specifications. The two work together. The traveling wheel 3 is responsible for setting the basic thickness, and the saw-shaped discharge port 4 is responsible for precise scraping on this benchmark. Thus, they jointly achieve precise thickness control from macro to micro.

[0070] To ensure the overall structure of the mortar spreader is stable, easy to manufacture, and cost-effective, the hopper 1 and guide channel 2 are designed as an integral molding structure or are fixedly connected by welding, and are made of lightweight metal materials (such as aluminum alloy, thin steel plate, etc.). The integral molding or welding connection ensures the sealing and strength of the mortar channel 6, while the lightweight material reduces the overall weight and facilitates worker operation.

[0071] To facilitate the smooth flow of mortar 6 into the guide channel 2 and prevent mortar 6 from clogging the hopper 1, a troweling tool is also provided. This troweling tool can be a trowel or a scraper, used to gently press down on the mortar 6 in the hopper 1 during the mortar spreading process, accelerating its flow into the guide channel 2. As an optional accessory, the troweling tool further ensures the smoothness of mortar spreading, especially when the mortar 6 has a high consistency.

[0072] Example 2

[0073] This embodiment also provides a construction method for mortar laying in brick wall construction, including the following steps:

[0074] Step 1: Select the appropriate size of mortar applicator according to the width of the brick wall, and select the appropriate size of walking wheels 3 according to the mortar joint thickness requirements;

[0075] Step 2: Place the mortar spreader on the already constructed brick wall base, aligning the discharge port 4 with the end of the brick wall;

[0076] Step 3: Fill hopper 1 with mortar 6;

[0077] Step 4: Push the mortar spreader along the brick wall direction, while simultaneously spreading the mortar 6 evenly on the brick surface from the discharge port 4;

[0078] Step 5: Stop moving when the mortar length reaches the preset value, and then proceed with bricklaying.

[0079] The following example, using brick wall construction in a shantytown renovation project, illustrates the application of this method in detail.

[0080] The above example, using the brick wall construction in the Heishitou shantytown renovation project in Baiyun District, Guiyang City as an example, provides a detailed description of the construction method provided by this invention.

[0081] The construction of the infill wall on the standard floor of Building 6 in this project required the use of 200mm thick aerated concrete blocks, with the mortar joint thickness controlled at 10mm, and M5 mixed mortar used for the masonry. According to the traditional manual mortar laying process, only about 15 square meters of masonry can be completed per workday, and the mortar joint thickness often fluctuates between 8-13mm, making it difficult to guarantee fullness.

[0082] Construction preparation stage:

[0083] Before construction, technicians selected the appropriate size mortar applicator based on the width of the brick wall (200mm). Simultaneously, based on the requirement of a 10mm mortar joint thickness, a pair of 60mm diameter wheels 3 were selected from the spare parts. These wheels 3 are quickly connected to the mortar applicator body via a detachable connecting rod 5, with the installation process taking approximately 30 seconds. Furthermore, based on the consistency of the mortar 6 on that day, the height of the serrated discharge port 4 was pre-adjusted to 10.5mm (accommodating slight settlement) and secured with locking screws.

[0084] On-site in place:

[0085] The operator places the assembled mortar spreader at the starting end of the brick wall after the base has been cleaned and leveled, and adjusts the position so that the edge of the discharge port 4 is flush with the end of the brick that has been laid, to ensure that the subsequent mortar spreading is seamlessly connected with the wall.

[0086] Mortar 6 filling:

[0087] Two workers work together: one uses a wheelbarrow to transport the mixed M5 mortar 6 to the work surface, while the other uses a shovel to fill the mortar 6 into the V-shaped hopper 1 of the mortar spreader. The amount of mortar filled at one time is about 0.03 cubic meters, which can meet the needs of a single mortar spreading length of about 3-4 meters.

[0088] Laying mortar:

[0089] After loading, the operator holds the mortar spreader handle with their right hand and uses a trowel in their left hand to gently press the mortar 6 in hopper 1 into the U-shaped guide channel 2. The spreader is then pushed forward along the wall at a constant speed of approximately 0.3 m / s. During this process, mortar 6 is observed to flow evenly from the serrated outlet 4, with the raised serrations naturally scraping and pressing the mortar 6 to form a uniformly thick and smooth mortar strip on the brick surface. On-site measurements show that the mortar width is consistently 200 mm, and the thickness fluctuates between 9.8 and 10.2 mm.

[0090] Masonry construction:

[0091] When the mortar layer reaches 3 meters in length, the workers stop pushing it. At this point, the subsequent masons immediately follow and begin laying blocks on the already laid mortar surface. The interval between laying the mortar and starting the masonry work is controlled before the mortar initially sets, ensuring the quality of bonding.

[0092] Comparison of effects:

[0093] According to on-site statistics, using the construction method of this invention, a single mortar-laying operation can complete a 3-meter length in just 30 seconds, improving efficiency by approximately 200% compared to traditional manual mortar laying (which requires laying mortar first and then leveling, taking about 90 seconds). In the 120-square-meter masonry project completed that day, only 3 workers (2 for material preparation and 1 for mortar laying) were needed to meet the material supply needs of 4 masons, saving 2 mortar-laying workers compared to traditional methods. Actual measurements by the supervision unit showed that the mortar joint thickness met the requirements at 98%, and the fullness exceeded 90%, both surpassing national standards.

[0094] User experience feedback:

[0095] Workers on site reported that the mortar spreader is lightweight and easy to push. The serrated discharge port 4 design prevents mortar 6 from accumulating or breaking. The detachable wheels 3 are easy to replace. After finishing work, the wheels can be removed to clean the hopper 1, making maintenance simple.

[0096] In summary, this embodiment fully verifies the feasibility and superiority of the construction method of the present invention. Through the five-step standardized operation of "selection-positioning-filling-pushing-masonry", the mortar laying process is truly simplified and its quality and efficiency are improved.

[0097] This is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
