Description

Technical Field

[0001] This invention belongs to the field of floor pouring technology, specifically a device for pouring cracks in sound-insulating and heat-preserving mortar flooring. Background Technology

[0002] Floor cracks may be caused by a combination of factors, including ground settlement, improper installation of floor expansion joints, long-term overloading, and external environmental factors. These cracks need to be addressed as soon as possible. Otherwise, over time, the floor at the crack will become increasingly fragile until the entire floor collapses.

[0003] The common method for treating floor cracks is grouting, where pre-prepared epoxy resin or thermal insulation mortar is poured into the cracks until it is flush with the floor surface. After it solidifies, curing is performed. However, because cracks are exposed to the external environment for extended periods, aggregate impurities may enter, creating dead zones that the initial grouting cannot reach, as well as other voids within the cracks. Therefore, it is necessary to wait for the mortar to settle and penetrate, requiring continuous replenishment of mortar into the cracks during this process. Currently used settlement methods are generally natural settlement and manual grouting, which are slow and have low accuracy and efficiency. This application proposes a sound-insulating and thermal insulation mortar floor crack pouring device to overcome these shortcomings. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides a device for pouring cracks in sound-insulating and heat-insulating mortar flooring.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sound-insulating and heat-insulating mortar floor crack pouring device, comprising a pouring base, wherein the interior of the pouring base is configured with a feeding system by rotating rollers and a conveyor belt, and the exterior of the pouring base is also provided with a drive motor for driving the feeding system; the crack pouring device further includes a cover plate disposed at the bottom, the cover plate comprising several straight plates spliced ​​end to end, and the ends of the straight plates are provided with fixing members for bolting and fixing; the cover plate sits on the floor crack and completely covers the crack; a feeding mechanism is also provided on one side of the pouring base, the feeding mechanism being used to inject heat-insulating mortar between the conveyor belt below and the floor crack.

[0006] Preferably, the feeding mechanism includes a mortar hopper located at the top of the device, a discharge pipe connected below the mortar hopper, and a discharge box fixed inside the casting base. The discharge box is used to inject thermal insulation mortar between the conveyor belt and the ground cracks, and the discharge pipe connects the mortar hopper and the discharge box.

[0007] Preferably, the casting base is also equipped with a vibrator, which is inserted downward into the feeding box to vibrate and defoam the thermal insulation mortar therein, and there is a gap between the feeding box and the conveyor belt.

[0008] Preferably, the rollers are arranged in a trapezoidal shape, and the bottom section of the conveyor belt is horizontal and above the ground, suspended at a height of 1-2 cm.

[0009] Preferably, the casting base is provided with a settling system, which is used to support the bottom section of the conveyor belt downward to keep it horizontal or concave downward;

[0010] The settling system includes a foldable L-plate pressed on a conveyor belt. The foldable L-plate is composed of a vertical plate and a horizontal plate connected by hinges. The horizontal plate is pressed on the conveyor belt. The foldable L-plate is slidably installed on the inner wall of the casting base and can move vertically up and down.

[0011] Preferably, the vertical plate and the horizontal plate are elastically supported by an elastic strut, and the initial included angle between the vertical plate and the elastic strut is greater than 90°. The two horizontal plates and the conveyor belt together form a cavity.

[0012] Preferably, the settling system further includes a telescopic rod, the output end of which is hinged to a connecting rod, and the bottom end of the connecting rod is hinged to the middle of the vertical plate.

[0013] Preferably, the roller located near the bottom side of the casting base near the feeding mechanism can be replaced by an adjustable roller. The surface of the casting base is provided with a groove, and the main shaft fixing insert of the adjustable roller can slide in the groove. The insert is supported downward by an elastic support rod 2, and a crossbeam is connected between the two elastic support rods 2. The output end of the telescopic rod is also hinged to a connecting rod 2, and the other end of the connecting rod 2 is hinged to the middle of the crossbeam.

[0014] Preferably, the casting base further includes a scraper disposed on one side of the casting base, the scraper abutting against the rotating roller to scrape off the thermal insulation mortar adhering thereon.

[0015] Preferably, the cover plate further includes corner bends, which are connected between straight plates or spliced ​​with other corner bends to accommodate the angle of the crack; the lengths of the straight plates need not be the same.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] This invention completely covers the cracks with a cover plate, preventing the cracks on both sides from seeping outwards during the central grouting process. Insulating mortar is poured inwards from the casting base, and through natural flow and the assistance of a conveyor belt, it reaches the ground surface. There, it is continuously pumped downwards into the cracks by the constant transport and gravity, settling into the air pockets within the cracks. The conveying system consists of rotating rollers and a conveyor belt, powered by a drive motor to assist the mortar flow, ensuring it is evenly spread across the cracks and in the air pockets below the conveyor belt, thus ensuring the accuracy and efficiency of the mortar filling. This invention sets the initial angle between the vertical plate and the first elastic support rod to greater than 90°, causing the two horizontal plates and the conveyor belt to enclose a cavity, which is maintained by the first elastic support rod. The cavity remains in place during the initial descent of the vertical and horizontal plates, allowing the top of the cavity (the bottom of the horizontal plate) to adhere to the conveyor belt. The cavity then shifts below the conveyor belt, forming an upward-facing depression capable of holding a certain amount of mortar. As the foldable L-plate descends further, the horizontal plate is supported, overcoming the upward tilt of the elastic struts and leveling itself. The mortar contained in the cavity is then pressed into the crack. This promotes mortar injection into the crack and accelerates the infiltration pressure into the crack's pores, preventing incomplete infiltration due to insufficient pressure and increasing the mortar infiltration rate, thus accelerating the settling speed.

Detailed Implementation

[0024] 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.

[0025] First embodiment, such as Figures 1 to 3 As shown, the present invention provides a sound-insulating and heat-insulating mortar floor crack pouring device, including a pouring base 100. The interior of the pouring base 100 is formed by a feeding system through a rotating roller 101 and a conveyor belt 102. The exterior of the pouring base 100 is also provided with a drive motor 105 for driving the feeding system. The crack pouring device also includes a cover plate 600 at the bottom. The cover plate 600 includes several straight plates 601 spliced ​​end to end. Both ends of the straight plates 601 are provided with fixing members 602 for bolting. The cover plate 600 sits on the floor crack and covers the crack completely. A feeding mechanism 200 is also provided on one side of the pouring base 100. The feeding mechanism 200 is used to pour heat-insulating mortar between the conveyor belt 102 below and the floor crack.

[0026] Before grouting the cracks in the floor, impurities must be cleaned from the cracks. High-pressure air ducts should be used to blow out as much debris as possible. Then, preliminary grouting should be performed on the cracks, focusing on wider sections. Alternatively, a vertical well can be drilled in the middle of the crack, and the insulating mortar can be slowly poured down through the well until it reaches level with the floor. Finally, the pouring device should be placed on the floor to allow the insulating mortar to settle.

[0027] The pouring device is positioned in the center of the floor crack. The cracks on both sides are completely covered by cover plates 600. Straight plates 601 are bolted to the bottom of the device, and adjacent straight plates 601 are joined together to cover the cracks and prevent outward seepage during the central pouring process. Insulating mortar is poured inward from the pouring base 100. Through natural flow and the auxiliary conveying of the conveyor belt 102, the mortar reaches the floor above, where it is continuously poured into the cracks by the constant transport and gravity, and settles downwards. The conveying system consists of rollers 101 and a conveyor belt 102, powered by a drive motor 105 to assist the mortar flow, ensuring it is evenly spread across the cracks and the cavities below the conveyor belt 102. The conveyor belt 102 is a nylon conveyor belt.

[0028] The mortar in the cavity will settle into the crack due to the pressure of the mortar above and its own weight, and eventually be compacted. After the settlement is complete, the cover plate 600 removal device is removed, and the mortar overflowing onto the ground is scraped off and leveled.

[0029] like Figures 3 to 5 As shown, the feeding mechanism 200 includes a mortar hopper 201 located at the top of the device, a discharge pipe 202 connected below the mortar hopper 201, and a discharge box 203 fixed inside the casting base 100. The discharge box 203 is used to inject thermal insulation mortar between the conveyor belt 102 and the ground crack. The discharge pipe 202 connects the mortar hopper 201 and the discharge box 203.

[0030] The feeding mechanism 200 is used to inject mortar into the cracks below. A certain amount of mortar is stored in the mortar hopper 201 and conveyed downwards to the discharge box 203 through the discharge pipe 202. The discharge box 203 is connected to the space below the casting base 100, and flows downwards into the cavity through the guide of its inner inclined wall and the conveyor belt 102. A pull-out valve plate is installed at the bottom of the mortar hopper 201. This valve plate controls the size of the mortar injection opening and can be adjusted according to the size of the crack and the injection speed. When the crack is small, the valve plate is slightly opened to maintain a uniform, small flow rate for gradual injection. When the crack is large, the opening is widened. However, the injection speed should also be judged based on whether mortar overflows from the edge of the cover plate 600. When mortar overflows from between the cover plate 600 and the ground, the opening needs to be closed to allow it to adjust naturally.

[0031] like Figure 3 and Figure 5 As shown, a vibrator 500 is also provided on the casting base 100. The vibrator 500 is inserted downward into the material box 203 to vibrate and defoam the thermal insulation mortar therein. There is a gap between the material box 203 and the conveyor belt 102.

[0032] To avoid poor structural stability due to numerous voids in the mortar and cracks after grouting, a pretreatment step to remove impurities from the cracks is necessary before grouting. Furthermore, the mortar needs to be vibrated and defoamed during grouting. The mortar flowing into the feed hopper 203 is vibrated and defoamed by a vibrator 500 installed on the device, which extends into the feed hopper 203 and promotes mortar flow. A gap is maintained between the feed hopper 203 and the conveyor belt 102 to prevent contact and interference from operation and vibration.

[0033] like Figure 3 As shown, the rollers 101 are arranged in a trapezoidal shape, and the bottom section of the conveyor belt 102 is horizontal and above the ground, suspended 1-2 cm above the ground.

[0034] The bottom portion of the conveyor belt 102 is horizontal, suspended above the ground, forming a cavity area between it and the ground. This area is used to refill the mortar into the crack as it settles naturally. The conveyor belt 102 covers the mortar and can apply downward pressure to promote mortar settlement, continuously permeating and injecting it into the pores inside the crack.

[0035] Second embodiment, such as Figure 3 As shown, the casting base 100 is equipped with a settling system inside. The settling system is used to support the bottom section of the conveyor belt 102 downwards to keep it horizontal or concave downwards. The settling system includes a foldable L-plate that presses on the conveyor belt 102. The foldable L-plate is composed of a vertical plate 302 and a horizontal plate 303 connected by hinges. The horizontal plate 303 presses on the conveyor belt 102. The foldable L-plate is slidably installed on the inner side wall of the casting base 100 and can move vertically up and down.

[0036] like Figure 4 As shown, the vertical plate 302 and the horizontal plate 303 are elastically supported by an elastic strut 305. The initial angle between the vertical plate 302 and the elastic strut 305 is greater than 90°. The two horizontal plates 303 and the conveyor belt 102 together form a cavity.

[0037] The foldable L-plate is used to maintain the rigidity of the conveyor belt 102, preventing it from being lifted up during mortar pouring. The vertical plate 302 and the horizontal plate 303 are hinged together, allowing them to open and close. The initial angle between the vertical plate 302 and the elastic support rod 305 is greater than 90°, creating a cavity between the two horizontal plates 303 and the conveyor belt 102, held in place by the elastic support rod 305. This cavity is maintained during the initial descent of the vertical plate 302 and the horizontal plate 303, causing the top of the conveyor belt 102 and the bottom of the cavity (i.e., the bottom of the horizontal plate 303) to adhere. The cavity then shifts below the conveyor belt 102, forming an upward-facing depression capable of holding a certain amount of mortar. As the foldable L-plate descends further, the horizontal plate 303 is supported, overcoming the upward rotation of the elastic support rod 305 and flattening it. The mortar contained in the cavity is then pressed down into the crack. This promotes the injection of mortar into the cracks and accelerates the seepage pressure into the crack pores, avoiding incomplete seepage due to insufficient pressure. Figure 2 As shown, a rubber sheet 107 is provided at the bottom edge of the casting base 100. The rubber sheet 107 replaces part of the rigid structure as an edge seal. When the internal grouting pressure is large and it can no longer be released downwards, it will be pushed up by the internal pressure and then mortar will be expelled outwards. This indicates that the mortar settlement has basically reached the target, or that the pressure of the foldable L plate is too large and the pressing speed is too fast, and adjustment is required.

[0038] like Figures 3 to 5As shown, the settlement system also includes a telescopic rod 301, the output end of which is hinged to a connecting rod 304, and the bottom end of the connecting rod 304 is hinged to the middle of the vertical plate 302.

[0039] The lifting and lowering of the foldable L-plate is achieved by driving the telescopic rod 301 and the connecting rod 304, forming a linkage mechanism that presses the foldable L-plate down, while the vertical plate 302 and the connecting rod 304 slide vertically on the inner wall of the casting base 100.

[0040] like Figure 5 As shown, the roller 101 located on the bottom side of the casting base 100 near the feeding mechanism 200 can be replaced by an adjustable roller 103. The surface of the casting base 100 is provided with a groove 106. The main shaft fixing insert of the adjustable roller 103 can slide in the groove 106. The insert is supported downward by the elastic support rod 400. A crossbeam 401 is connected between the two elastic support rods 400. The output end of the telescopic rod 301 is also hinged to a connecting rod 306. The other end of the connecting rod 306 is hinged to the middle of the crossbeam 401.

[0041] When the horizontal plate 303 is pressed down, a portion of the conveyor belt 102 will be buried downwards. Therefore, a second connecting rod 306 is provided to compensate for this portion of the length. When the telescopic rod 301 retracts, it will drive the second connecting rod 306 to retract synchronously. The second elastic support rod 400 is set in the chute 106 and is driven to move obliquely upwards by the connected second connecting rod 306, thus compensating for the middle of the conveyor belt 102.

[0042] When the adjustable roller 103 moves upward at an angle, the grouting port below the conveyor belt 102 is enlarged. The telescopic rod 301 pushes the connecting rod 306 back to its original position. When the adjustable roller 103 is lowered, it will bite off a portion of the mortar and supply it downward to the conveyor belt 102. Therefore, the elastic support rod 400 and the connecting rod 306 pushing the adjustable roller 103 downward can promote the flow of mortar to the cavitation area and prevent blockage at that location.

[0043] like Figure 3 As shown, the casting base 100 also includes a scraper 104 disposed on one side of the casting base 100. The scraper 104 abuts against the rotating roller 101 to scrape off the thermal insulation mortar adhering thereon.

[0044] The scraper 104 is used to scrape off the mortar adhering to the surface of the conveyor belt 102 to prevent it from accumulating on the surface and causing misfit failure, and also plays a certain role in blocking.

[0045] like Figure 1 and Figure 2As shown, the cover plate 600 also includes a corner bend 604, which is connected between the straight plates 601 or spliced ​​with other corner bends 604 to accommodate the angle of the crack; the lengths of the straight plates 601 do not need to be the same.

[0046] The cover plate 600 can accommodate floor cracks of various widths and completely cover them. For relatively straight cracks, straight plates 601 of different lengths can be combined to cover the cracks. For meandering cracks, a combination of corner pieces 604 and straight plates 601 can be used to cover the cracks. At the same time, for bifurcated cracks, this type of straight plate 601 and corner piece 604 can also be used to cover them, that is, sealing strips 603 (not shown in the figure) are added to the edges of the straight plate 601 or corner piece 604 to form a more complex configuration for covering bifurcated cracks.

[0047] Working principle and usage process of this invention:

[0048] The pouring device is positioned in the center of the ground crack, with the cracks on both sides completely covered by cover plates 600. Straight plates 601 are bolted to the bottom of the device, and adjacent straight plates 601 are joined together to cover the cracks and prevent outward seepage from the cracks on both sides during the central pouring process. Insulating mortar is poured inward from the pouring base 100. Through natural flow and auxiliary conveying by the conveyor belt 102, the mortar reaches the ground surface. Under the continuous transport and pressure of gravity, it is continuously poured into the cracks and settles downwards. The conveying system consists of rotating rollers 101 and a conveyor belt 102, powered by a drive motor 105 to assist the mortar flow, ensuring it is evenly spread across the cracks and in the cavities below the conveyor belt 102. Inside the device, the foldable L-plate is driven to press down by the telescopic rod 301. After the foldable L-plate descends further, the horizontal plate 303 will be supported, thus overcoming the upward flipping of the elastic support rod 305 and making it flat. As a result, the mortar contained in the cavity will be pressed down into the crack, promoting the downward penetration of the mortar in the crack.
