Description

Technical Field

[0001] This invention belongs to the field of mobile precast mortar tank technology, and more specifically, relates to a construction method for mobile precast mortar tanks. Background Technology

[0002] In the construction industry, mortar tanks are widely used as key equipment around individual buildings to improve the efficiency and convenience of plastering operations. To ensure the stable operation of mortar tanks and effectively distribute their loads, a dedicated foundation structure is usually constructed beneath them, mainly including two types: brick masonry mortar tank foundations and cast-in-place concrete mortar tank foundations.

[0003] Brick-built mortar tank foundations have been widely used in previous projects due to their readily available materials and simple construction. However, once built, these foundations remain stationary and cannot adapt to the dynamic changes in construction site conditions. As the project progresses, the distance workers need to travel to pick up materials using wheelbarrows may gradually increase, causing the originally selected mortar tank foundations to no longer meet the actual needs and affecting construction efficiency.

[0004] On the other hand, while cast-in-place concrete mortar tank foundations offer higher load-bearing capacity and stability, they also face the problem of being immovable. More importantly, whether brick or cast-in-place concrete foundations, it is difficult to reuse materials after the project is completed. These foundation structures often require manual demolition, during which materials are often damaged and cannot be effectively recycled, increasing construction costs and wasting resources. Summary of the Invention

[0005] In view of this, the present invention provides a construction method for a mobile precast mortar tank, which can solve the problems of existing mortar tanks being unable to be moved or reused.

[0006] This invention is implemented as follows:

[0007] This invention provides a construction method for a mobile precast mortar tank, comprising the following specific steps:

[0008] S10: Clean the construction site, compact the ground, calibrate the level, and then lay out the lines using a line-laying device. The range of the lines should match the size of the mortar tank.

[0009] S20: Fix the embedded parts on the horizontal plane after the line is laid out, and lay a waterproof tarpaulin to fix the waterproof tarpaulin to the embedded parts.

[0010] S30: According to the drawings of the precast mortar tank, each part of its structure is cast using templates, and an anti-sticking layer is fixed on the surface;

[0011] S40: Move the first assembly, the second assembly, and the third assembly that make up the precast mortar tank to the construction site, and fix the first assembly and the second assembly to the embedded part.

[0012] S50: Install positioning components on the top of the first and second combined components so that the third combined component can be quickly connected and fixed to the top of the first and second combined components.

[0013] S60: After filling with water, check the sealing of the assembled mortar tank. Once it is confirmed to be completely sealed, complete the construction of the mortar tank.

[0014] S70: After the mortar tank is used up, it shall be disassembled and moved.

[0015] Based on the above technical solution, the construction method of a mobile precast mortar tank of the present invention can be further improved as follows:

[0016] The line-laying device includes a central shaft, a support assembly, a level assembly, and a marking assembly. The central shaft is positioned at the center, the support assembly is fixed to the side wall of the central shaft, and the marking assembly is fitted onto the central shaft and limited and supported by the support assembly. The support assembly is used to determine the horizontal plane on which the marking assembly rotates on the side wall of the central shaft. The level assembly is connected to the top of the central shaft, and the level assembly is used to ensure the verticality of the central shaft and to keep the central shaft fixed by gravity.

[0017] The central shaft includes a fixed rod, a slide rail, and an insertion drill. The insertion drill is fixed to the top of the fixed rod and is used to fix the wire laying device on the ground. The fixed rod is a vertical rod structure, and the slide rail is set on the side wall of the fixed rod. The insertion drill is a hexagonal structure with a channel running from the bottom to the top, which is used to remove the soil at the bottom when rotating and drilling downwards into the ground.

[0018] The support assembly is fixed to the upper and lower sides of the slide rail, including a fixed part and a movable part. The fixed part is fixed to the bottom of the slide rail and is flush with the bottom edge of the slide rail. The movable part is fixed to the top of the slide rail by threads and is flush with the top edge of the slide rail. The diameter of the fixed part is larger than the diameter of the movable part. The top of the slide rail is provided with threads, and the threads match the threads on the inner wall of the movable part.

[0019] The marking assembly is sleeved on the slide rail and fixed within the slide rail by the fixing member and the movable member; the fixing member is used to support the weight of the marking assembly; the marking assembly includes an inner rotating ring, a gear, an outer rotating ring, and a support rod, the gear includes a fixed gear and a rotating gear, the fixed gear is fixed to the outer wall of the slide rail, the rotating gear is fixed to the inner wall of the inner rotating ring, and the fixed gear and the rotating gear are meshed; the height of the fixed gear and the rotating gear is the same as the height between the fixing member and the movable member; the outer rotating ring is a double-ring structure, with four triangular irons symmetrically fixed inside, all of which are equilateral triangles, and the corresponding positions of adjacent triangular irons are spaced 90° apart; two corners of each triangular iron are fixed to the double ring of the outer rotating ring, and the other corner is located at the center of the double ring of the outer rotating ring; nozzles are fixed to the bottom of the three corners of each triangular iron, the nozzles contain marking powder, and the bottom of the nozzles points vertically downwards, for marking lines on the horizontal plane by spraying marking powder;

[0020] The level assembly includes a support rod, a plumb line, and weights. A plug is fixed to the top of the central shaft, and a through hole is provided at the center of the support rod. The support rod is fixed to the top of the central shaft by inserting the plug through the through hole. The weights are fixed to the left and right sides of the support rod symmetrically through the plumb line. The gravity of the weights at the symmetrical positions keeps the central shaft in a vertically downward state.

[0021] The outer diameter and inner diameter of the outer rotating ring are the same as the outer diameter and inner diameter of the precast mortar tank, respectively.

[0022] Furthermore, the specific steps for cleaning the construction site, compacting the ground, calibrating the level, and then using a layout device to lay out the lines, with the layout range matching the size of the mortar tank, are as follows:

[0023] The first step is to remove debris and trash from the site, and check the ground for any obvious potholes or cracks and repair them accordingly.

[0024] The second step is to use a vibratory tamper to evenly compact the entire ground surface to improve its density and load-bearing capacity.

[0025] The third step is to calibrate the levelness of the ground using an optical level.

[0026] The fourth step is to move the wire-laying device to the construction site for assembly;

[0027] The fifth step is to quickly lay out lines on the ground to determine the fixed positions of the embedded parts;

[0028] The specific steps for moving the wire-laying device to the construction site for assembly include:

[0029] The first step is to select the center of the mortar tank installation and insert the fixing rod vertically into the ground corresponding to the center;

[0030] The second step is to fix the scribing assembly to the fixing member and to screw the movable member to the top of the scribing assembly.

[0031] The third step is to fix the level assembly to the top of the fixed rod, and adjust the position of the plumb line and the weight so that the fixed rod is always perpendicular to the ground.

[0032] The fourth step is to place marking powder inside the nozzle;

[0033] The specific steps for quickly laying out lines on the ground to determine the fixed positions of the embedded parts include:

[0034] Rotate the scribing assembly to mark the starting point of the four triangular irons at the angles away from the outer rotating ring. Thereafter, mark the positions of the four triangular irons at the angles away from the outer rotating ring every 1 / 12 of the gear circumference, and perform multiple rotations for calibration.

[0035] The central shaft, the support assembly, and the scribing assembly are all made of lightweight materials.

[0036] Furthermore, the embedded parts include 12 units, each fixed at the marked position of the marking assembly; each embedded part includes a fixing part and a clamping part, the fixing part is a four-sided pyramid structure, embedded at the marked position; the clamping part is disposed on the top of the fixing part, the clamping part includes a compression plate and a connecting spring, one end of the connecting spring is fixed to both sides of the top of the fixing part, and the other end is connected to the compression plate; there are at least two compression plates and connecting springs, the two compression plates are inclined, and the included angle between their contacting top inner walls is 30-60°.

[0037] Furthermore, the specific steps for fixing the embedded parts on the horizontal plane after the layout include:

[0038] The first step is to dig a hole with a diameter larger than the bottom diameter of the fixing part at each of the 12 positions marked when the marking component is used to lay out the lines. After the fixing part is pre-buried in the corresponding hole, the area around the hole is compacted.

[0039] The second step is to adjust the embedded parts to be vertically upward during the compaction process;

[0040] The specific steps for laying the waterproof tarpaulin and fixing it to the embedded part include:

[0041] The first step is to draw a circle on the top of the waterproof tarpaulin that is identical to the inner and outer walls of the bottom of the mortar tank using a compass;

[0042] The second step is to draw points in the middle of the two circles according to the positions of the 12 marks;

[0043] The third step is to draw cross lines at 12 points, with the cross lines confined between two circles;

[0044] Fourth step, fix the waterproof tarpaulin on the horizontal surface, with each corresponding cross line passing through the embedded part;

[0045] Fifth step: tidy up the edges of the cross lines.

[0046] Furthermore, the first and second assembled components are symmetrical structures, each being a semi-circular structure cast in concrete, with an inward recess on one side and an outward protrusion on the other side. The inward recess and the outward protrusion are correspondingly arranged to splice and fix the first and second assembled components together. The diameter of the recess and the protrusion is smaller than the outer wall diameter of the first and second assembled components, but larger than the inner wall diameter of the first and second assembled components.

[0047] The top of the first assembly and the second assembly are provided with downward-facing insertion slots;

[0048] The bottom center of the first assembly and the second assembly each have six grooves evenly distributed, and the size of the grooves is the same as the size of the pressing part;

[0049] The third assembly is a ring-shaped structure with a plug-in protrusion at its bottom. The plug-in protrusion has the same size as the plug-in slots at the top of the first and second assemblies. The top of the third assembly is provided with a lifting ring, which is used to facilitate lifting the third assembly for installation.

[0050] The bottom of the concave surface of the first and second combined components is provided with an inwardly recessed double-layered annular groove, and a rubber ring of the same shape is fixed thereon during installation to seal the bottom of the mortar tank composed of the first and second combined components.

[0051] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the symmetrical structure facilitates the installation and disassembly of the mortar tank, and the protrusions and recesses facilitate the docking of the first and second combined components, the docking of the first and third combined components, and the docking of the second and third combined components.

[0052] The annular third assembly is designed to prevent the first and second assemblies from separating from the top during use, thus extending their service life after installation.

[0053] Furthermore, the specific steps of casting each part of the structure according to the drawings of the precast mortar tank using templates and fixing an anti-adhesion layer on the surface include:

[0054] The first step is to clean the mold, ensuring that the inner surface of the mold is clean, free of oil and dust;

[0055] The second step is to install each part of the template according to the dimensions in the drawings, ensuring that the template is firmly fixed and accurately assembled according to the design dimensions.

[0056] The third step is to use a level and measuring tools to check the alignment of the template to ensure that it meets the design requirements in all directions;

[0057] The fourth step is to support the formwork to ensure its stability during the pouring process;

[0058] Fifth step, evenly apply an anti-stick coating material to the inner surface of the template;

[0059] The sixth step is to mix cement, sand, gravel, and water according to the mixing ratio requirements, and stir them into a uniform concrete.

[0060] Step 7: Pour the concrete into the formwork, ensuring that each part is filled evenly. Use a vibrator to vibrate the concrete to remove air bubbles and ensure that the concrete is dense.

[0061] Step 8: Use a scraper or trowel to smooth the concrete surface, ensuring it is smooth and flat.

[0062] The ninth step is to cure the poured concrete and keep it moist.

[0063] Step 10: After the concrete reaches its design strength, remove the formwork according to the specified time.

[0064] Step 11: Check whether the surface of the precast mortar tank after demolding meets the requirements and ensures that there are no defects;

[0065] Step 12: Fix the anti-stick layer on the surface of each part of the precast mortar tank.

[0066] The beneficial effects of adopting the above-mentioned improved solution are as follows: Furthermore, the material of the anti-stick layer is polytetrafluoroethylene, polyurethane, epoxy resin, silicone rubber, or a special anti-stick coating.

[0067] Furthermore, the specific steps for fixing the first assembled component and the second assembled component to the embedded part include:

[0068] The first step is to lift the first assembly and then adjust its position on top of the embedded part accordingly.

[0069] The second step is to slowly lower the assembly by swaying it left and right until it aligns with the six pre-embedded parts before placing it down.

[0070] Third, repeat the above process to fix the second assembly to the corresponding 6 embedded parts;

[0071] Fourth, the construction workers enter the structure composed of the first and second combined components and fix the rubber ring in the double-layer ring groove.

[0072] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting the first and second combined components to be fixedly connected with the embedded parts, the shaking of the first and second combined components during use is avoided, and the risk of collapse of the first and second combined components is reduced.

[0073] The rubber ring prevents cement from overflowing from the bottom of the first and second assembly components.

[0074] Furthermore, the rubber ring is made of chloroprene rubber, butyl rubber, or ethylene propylene rubber.

[0075] Furthermore, the positioning component includes docking ears and guide ropes. The docking ears include at least one set, with each set including two, which are respectively fixed at corresponding positions on the first assembly, the second assembly, and the third assembly. One end of the guide rope is fixed in the docking ears on the first assembly and the second assembly, and the other end passes through the docking ear on the corresponding third assembly.

[0076] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting up a positioning component, it is convenient to dock the third assembly above the first and second assemblies, reducing the time spent repeatedly during hoisting and improving efficiency.

[0077] Furthermore, the specific steps for installing positioning components on the top of the first and second assembled components, so that the third assembled component can be quickly connected and fixed to the top of the first and second assembled components, include:

[0078] The third assembly is lifted so that the guide rope passes through the docking lug on the third assembly. The guide rope is then retracted inward to guide the third assembly to the corresponding position for insertion and fixation.

[0079] Compared with existing technologies, the beneficial effects of the mobile precast mortar tank construction method provided by this invention are:

[0080] Freedom of site selection: The first, second and third assembly components can be hoisted and assembled at any time for installation and disassembly, and the installation site can be freely selected according to the user's wishes.

[0081] High efficiency and low labor costs: This invention allows for fast installation and dismantling, saving labor costs. Compared to traditional manual layout and masonry, or formwork and concrete pouring, it only requires prefabricated concrete components that are transported by truck for immediate hoisting and assembly, saving time.

[0082] Material saving: This invention saves materials, allowing for one-time installation and repeated use. After the project is completed, the detachable components can be hoisted away, reducing the footprint, and stored in a warehouse for reuse at the next construction site.

[0083] High precision and convenient construction: The present invention uses a positioning component to facilitate the docking of the third assembly with the first and second assemblies during hoisting, thereby improving docking accuracy and reducing docking time. Attached Figure Description

The support assembly 12 is used to determine the horizontal plane on which the line-marking assembly 14 rotates on the side wall of the central shaft 11. The top of the central shaft 11 is connected to the level assembly 13, which is used to ensure the verticality of the central shaft 11 and to keep the central shaft 11 fixed by gravity.

[0103] The central shaft 11 includes a fixed rod 111, a slide rail 112, and an insertion drill 113. The insertion drill 113 is fixed to the top of the fixed rod 111 and is used to fix the wire laying device 10 to the ground. The fixed rod 111 is a vertical rod structure, and the slide rail 112 is set on the side wall of the fixed rod 111. The insertion drill 113 is a hexagonal structure with a channel running from the bottom to the top, which is used to remove the soil at the bottom when rotating and drilling downwards into the ground.

One side of each component has an inward recess, and the other side has an outward protrusion. The inward recess and the outward protrusion are correspondingly arranged to splice and fix the first assembly component 30 and the second assembly component 40. The diameter of the recess and the protrusion is smaller than the outer wall diameter of the first assembly component 30 and the second assembly component 40, but larger than the inner wall diameter of the first assembly component 30 and the second assembly component 40.
