Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, specifically to a composite mortar moisture retention curing device and method. Background Technology

[0002] Composite mortar is widely used in building reinforcement projects, with applications including reinforcing interior and exterior walls, strengthening internal and external corners of beams and columns, reinforcing curved surfaces in tunnels, and reinforcing various irregularly shaped components. After the mortar has set, it must be continuously and evenly kept moist for curing. If the moisturizing is uneven or there are blind spots in the spraying, the reinforced layer is prone to defects such as shrinkage cracks, sandblasting, insufficient strength, and color differences in the finish. M30 high-strength reinforcing composite mortar has demanding hydration conditions and requires even higher levels of long-term, uniform moisturizing. Traditional curing methods cannot simultaneously meet the curing needs of various wall shapes and areas requiring reinforcement.

[0003] The main curing methods used at reinforcement construction sites are manual watering and spraying. M30 reinforcing mortar has high strength, and its application is often done in thin layers. Early hydration shrinkage and drying shrinkage stress concentration, combined with the constraint of the internal steel reinforcement layer, makes the reinforced surface highly susceptible to cracking. Manual watering has a short moisturizing effect, and the thin-layer reinforcing mortar loses water quickly, resulting in uneven strength development and overall durability degradation. Therefore, most reinforcement projects use spraying for curing.

[0004] Existing traditional spray curing equipment is only suitable for reinforcing flat walls, and the entire machine lacks an adjustable structure. When reinforcing corners or curved tunnel surfaces, the entire machine needs to be disassembled and reassembled to fit the working conditions, limiting the applicability of a single unit to a single scenario. Multiple sets of curing supports of different specifications need to be purchased on-site, resulting in high equipment procurement and storage costs, and complicated disassembly, assembly, and transportation procedures, severely reducing the construction efficiency of wall reinforcement and related curing. Summary of the Invention

[0005] The purpose of this invention is to provide a composite mortar moisture retention and curing device and method to solve the problem that traditional spraying equipment in the prior art is only suitable for flat walls and has no overall structure adjustment function.

[0006] The technical problem to be solved by the present invention can be achieved by the following technical solution: a composite mortar moisture retention and curing device, comprising an upper adjusting bracket, a lower adjusting bracket, a first support rod, a second support rod, a first pipe, a water distribution pipe and a micro nozzle; The upper adjusting bracket is fixedly equipped with a first support rod and a second support rod at both ends, and the lower adjusting bracket is engaged with the two support rods at both ends. The support rod includes a first connector and a second connector that are rotatably connected, and is respectively equipped with a first adjustment mechanism, a second adjustment mechanism, and corresponding third connectors and fourth connectors; The first pipe is spirally wound between the two support rods, and the lower connector is connected to the water inlet valve. The first pipe is connected to the water distribution pipe with a micro nozzle through the connector. The upper and lower supports are connected by a connecting crossbar at the top. The upper and lower supports can be switched to straight, triangular, or right-angle shapes to suit spray curing of flat, curved, and inside-out corner walls.

[0007] Preferably, the first connector and the second connector are rotatably coupled via a first rotating shaft, and the first rotating shaft is fixedly connected to the third support rod.

[0008] Preferably, the first adjustment mechanism and the second adjustment mechanism are telescopic rods, and the lower adjustment bracket is slidably engaged with the support rod; The third connector and the fourth connector are provided with limiting elements and limiting grooves, and the connecting head is slidably disposed in the limiting groove.

[0009] Preferably, it also includes an adaptive telescopic component, comprising a slide rod, a winding component, and a folding component. The upper and lower ends of the slide rod are respectively connected to a first mounting plate and a second mounting plate, and a plurality of winding components are slidably mounted on the slide rod.

[0010] Preferably, the folding assembly is a scissor-type linkage structure, including a linkage link and an end link, with each link hinged together and the two ends rotatably connected to a first mounting plate and a second mounting plate, respectively.

[0011] Preferably, the winding assembly includes a first winding drum and a second winding drum that rotate and cooperate with each other. The drum body has a slot and a through hole for the slide rod to pass through and the water distribution pipe to exit.

[0012] Preferably, the second winding drum is provided with a first arc-shaped partition and a second arc-shaped partition arranged concentrically, and the water distribution pipe is folded and spirally wound between the two sets of arc-shaped partitions.

[0013] Preferably, the second winding drum is further provided with a third arc-shaped partition, and the coil spring is housed inside the interlayer formed by the second arc-shaped partition and the third arc-shaped partition.

[0014] Preferably, it also includes a clamping mechanism with adjustable spacing, wherein the clamping mechanism uses a long clamping plate to clamp the nozzleless section of the water distribution pipe that passes through the winding assembly, thereby blocking the flow of internal accumulated water.

[0015] Preferably, the first support rod and the second support rod can be connected to an extension rod to expand the spray coverage area of ​​the equipment.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: This device is connected to an external water pipe and an inlet valve. Water flows through the third and fourth connectors on the lower regulating bracket to the two sets of first pipes, and then through several connectors to be distributed to each branch pipe. Multi-channel synchronous spraying achieves uniform moisture retention throughout the wall, effectively eliminating maintenance dead spots, ensuring stable hydration of composite mortar, and reducing quality defects such as wall cracking and sanding. The upper and lower adjustable brackets can be switched between three forms: straight, triangular, and right-angle, to adapt to flat, curved, and right-angled walls respectively. When adjusted to a triangular shape, the water pipe can be bent into an arc shape to fit the curved wall by pulling it with the support rod. When the bracket is adjusted to a right angle, the water pipe simultaneously forms a right angle to fit the corner. A single unit can cover multiple construction conditions, eliminating the need for multiple sets of curing frames, saving the steps of disassembling and reassembling the whole machine, reducing equipment procurement and storage costs. Moreover, the pipeline can adapt to the shape of the bracket, and the nozzle is close to the mortar surface, resulting in better fit and uniformity of curing irregularly shaped walls. The operation of switching between working conditions is simple, which greatly improves the efficiency of on-site spraying curing of composite mortar. Attached Figure Description

[0019] 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.

[0020] Example 1 Traditional sprinkler systems are only suitable for flat walls and lack overall structural adjustment. When dealing with corners or curved walls, the entire machine must be disassembled and reassembled to adapt to the working conditions, limiting the applicability of a single unit. Multiple sets of maintenance supports of different specifications need to be purchased on-site, resulting in high equipment procurement and storage costs, cumbersome disassembly and transportation processes, and significantly reducing maintenance efficiency.

[0021] like Figure 1 As shown, a composite mortar moisture retention and curing device is provided, including an upper adjusting bracket 1 and a lower adjusting bracket 2. A first support rod 3 and a second support rod 5 are fixedly mounted at both ends of the upper adjusting bracket 1, respectively. Both ends of the lower adjusting bracket 2 are fixedly engaged with the first support rod 3 and the second support rod 5, respectively. The first support rod 3 and the second support rod 5 have the same structure. Specifically, taking the first support rod 3 as an example... Figure 2 As shown, the device includes a first connector 101, a second connector 104 rotatably connected to the first connector 101, a first adjusting mechanism 102 fixedly connected to the first connector 101, a third connector 103 fixedly connected to the output end of the first adjusting mechanism 102, a second adjusting mechanism 105 fixedly mounted on the second connector 104, and a fourth connector 106 fixedly mounted to the output end of the second adjusting mechanism 105. The maintenance equipment also includes a third support rod 4, as shown. Figure 3 and Figure 4 As shown, the first connector 101 and the second connector 104 are rotatably connected by the first rotating shaft 107, and the first rotating shaft 107 is fixedly connected to the third support rod 4.

[0022] like Figure 1 As shown, the first support rod 3 and the second support rod 5 are located between the upper adjusting bracket 1 and the lower adjusting bracket 2, and a first pipe 7 is spirally wound around them. The first and second ends of the first pipe 7 are connected to the third connector 103 and the fourth connector 106 on the upper adjusting bracket 1 and the lower adjusting bracket 2, respectively. The third connector 103 and the fourth connector 106 on the upper adjusting bracket 1 are fixedly connected to the end of the first pipe 7, and the third connector 103 and the fourth connector 106 on the lower adjusting bracket 2 are connected to the end of the first pipe 7. A water inlet valve 13 is connected to the third connector 103 and the fourth connector 106 on the lower adjusting bracket 2. The water inlet valve 13 is connected to the corresponding first pipe 7 through the third connector 103 and the fourth connector 106 to continuously supply water to the first pipe 7.

[0023] like Figure 3 and Figure 5 As shown, the first pipe 7 is provided with several connecting heads 8, and each of the several connecting heads 8 is connected to a water distribution pipe 9. The other end of the water distribution pipe 9 is connected to the corresponding connecting head 8 on the other side of the first pipe 7. Several micro nozzles 10 are installed on the several water distribution pipes 9.

[0024] like Figure 1 The diagram also includes two sets of support rods 14, both of which are located between the corresponding water distribution pipe 9 and the upper adjusting bracket 1. The top ends of the two sets of support rods 14 are fixedly connected by a connecting crossbar 6.

[0025] The working principle of moisturizing and maintenance equipment: such as Figure 1 and 3As shown, in use, the external water pipe is connected to the inlet valve 13. The external water pipe supplies water to two sets of first pipes 7 through the third connector 103 and the fourth connector 106 on the lower adjusting bracket 2. The first pipes 7 then supply water to several branch pipes 9 through several connecting heads 8, thereby achieving spray curing of the reinforced wall surface. The curing device in this embodiment can also be adapted to flat walls, curved walls, and right-angled walls. When curing a flat wall is required, the upper adjusting bracket 1 is adjusted to a straight line shape for spraying. When it is necessary to maintain the curved wall, adjust the upper adjustment bracket 1 into a triangular shape, and then pull the support rod 14 outward to pull the corresponding water pipe 9 outward, adjust the tension of the water pipe 9 to better match the curved surface of the curved wall, and roughly match the shape of the curved wall, and then spray. When it is necessary to reinforce the right-angled inside and outside corners, adjust the upper adjustment bracket 1 and the lower adjustment bracket 2 into a right-angle shape. At this time, the water pipe 9 also becomes a right-angle shape, matching the shape of the corner and meeting the spraying requirements of the corner.

[0026] When in use, the first support rod 3, the second support rod 5, and the third support rod 4 need to be fixed to an external bracket or the ground. The first support rod 3, the second support rod 5, and the third support rod 4 can all be connected to extension rods to further increase the coverage area of ​​the device.

[0027] It should be emphasized that the core improvement of this embodiment lies in the following: the external water pipe of this device is connected to the inlet valve 13, and the water flows through the third connector 103 and the fourth connector 106 on the lower adjusting bracket 2 to the two sets of first pipes 7, and then through several connecting heads 8 to the various branch pipes 9. The multi-channel synchronous spraying achieves uniform moisturization of the entire wall, effectively eliminating maintenance dead corners, ensuring stable hydration of M30 composite mortar, and reducing quality defects such as wall cracking and sanding. The upper adjusting bracket 1 and the lower adjusting bracket 2 can be switched to three forms: straight, triangular, and right-angle, respectively adapted to the plane. For curved, right-angled, and internal / external corner walls, when adjusted to a triangular shape, the water distribution pipe 9 can be bent and stretched into an arc shape to fit the curved wall surface by using a support rod. When the support is adjusted to a right angle, the water distribution pipe 9 simultaneously forms a right angle to fit the corner. A single unit can cover multiple construction conditions, eliminating the need for multiple sets of curing frames, saving the steps of disassembling and reassembling the entire machine, reducing equipment procurement and storage costs. Moreover, the pipeline can adapt to the shape of the support and deform accordingly, and the nozzle is close to the mortar surface, resulting in better fit and uniformity of curing irregularly shaped walls. The operation of switching between working conditions is simple, greatly improving the efficiency of on-site spraying curing of composite mortar.

[0028] Example 2 Understandably, in Example 1, the on-site conditions for wall reinforcement construction are complex, with significant differences in the size of the mortar reinforcement area for different components and construction sections. Fixed-size curing devices can only match a single-specification reinforcement surface, resulting in poor versatility. Frequent equipment changes are required when changing curing areas, significantly increasing the workload. This addresses this practical pain point.

[0029] This embodiment proposes a composite mortar moisture retention and curing device with flexibly adjustable overall dimensions, which can adapt to various sizes of reinforced walls, simplifying on-site curing operations, such as... Figure 2 As shown, in this embodiment, the first adjustment mechanism 102 and the second adjustment mechanism 105 in the upper adjustment bracket 1 and the lower adjustment bracket 2 are actually telescopic rods. The two ends of the lower adjustment bracket 2 are respectively in sliding engagement with the first support rod 3 and the second support rod 5. Figure 3 and Figure 5 As shown, limiting members 11 are fixedly provided on the third connector 103 and the fourth connector 106 on the first support rod 3. Limiting grooves 12 are formed on the limiting members 11, and the connecting heads 8 on the two sets of first pipes 7 are slidably located on the limiting grooves 12. In this embodiment, the water distribution pipe 9 is an elastic and stretchable pipe body.

[0030] The working principle of adjustable moisturizing and maintenance equipment: such as Figure 1 As shown, depending on the reinforcement area, the first adjustment mechanism 102 and the second adjustment mechanism 105 can be adjusted first. The length of the first adjustment mechanism 102 and the second adjustment mechanism 105 can be adjusted by controlling the extension and retraction of the telescopic rod until the area enclosed by the first adjustment mechanism 102 and the second adjustment mechanism 105 can cover the width of the reinforcement area. Then, by pulling down the lower adjustment bracket 2, the longitudinal length of the maintenance equipment can be adjusted, making the overall working area of ​​the maintenance equipment larger than the reinforcement area. During the downward pulling of the lower adjustment bracket 2, the first pipe 7 spirally wound on the second support rod 5 will be stretched, changing the spiral radius. The spacing of the several water distribution pipes 9 connected to the first pipe 7 will also change, i.e., the distribution area of ​​the water distribution pipes 9 will change. As the overall working area of ​​the maintenance equipment adapts, the spraying area changes accordingly. During the deformation of the first pipe 7, which is spirally wound on the second support rod 5, the positions of several connecting heads 8 distributed on the first pipe 7 also change accordingly, which may cause pulling or even damage to the water distribution pipe 9. When the first pipe 7 deforms, the connecting heads 8 will change position with the deformation of the first pipe 7, causing the position of the connecting heads 8 to shift. Therefore, this embodiment uses a limiting groove 12 to limit the position of several connecting heads 8. Under the action of the limiting groove 12, the several connecting heads 8 can only move up and down, thereby adapting to the change in the distance between the upper adjusting bracket 1 and the lower adjusting bracket 2. After the adjustment is completed, the first pipe 7 is connected to the external water pipe to achieve water supply and spraying.

[0031] It should be emphasized that the core improvement of this embodiment is as follows: This device can adjust the lateral length of the first adjustment mechanism 102 and the second adjustment mechanism 105 according to the size of the wall reinforcement area to match the width of the reinforcement area by using the telescopic rod, and then pull down the adjustment bracket 2 to adjust the longitudinal length of the equipment. The overall spraying range can be flexibly adapted to reinforcement surfaces of different sizes without the need to replace multiple sets of maintenance equipment. The first pipe 7, spirally wound on the second support rod 5, deforms synchronously with the stretching of the bracket, automatically changing the spacing of the water distribution pipes 9 to match the spraying area, eliminating the need for manual disassembly and assembly of the pipeline. At the same time, a limiting groove 12 is set to limit the connecting head 8. When the pipeline deforms, the connecting head 8 only slides vertically along the limiting groove 12, only stretching the first pipe 7 between adjacent connecting heads 8, preventing the connecting head 8 from shifting and pulling at will, damaging the water distribution pipes 9, ensuring the stability of the spraying pipeline structure, improving the operational reliability of the equipment during adjustment, and the external water pipe can spray and maintain normally after the adjustment is completed.

[0032] Example 3 It is understandable that in Embodiment 2, after the upper adjusting bracket 1 and the lower adjusting bracket 2 are extended and retracted to adjust their lengths, the spray coverage area corresponding to each water distribution pipe 9 will change synchronously. If a fixed-length elastic stretchable water distribution pipe 9 is used, the water flow velocity will decrease, affecting the change in spray rate and potentially damaging the pipes. Furthermore, the stretching range is limited; when the spray area is much larger than the stretching length, individual pipes must be replaced according to the maintenance dimensions. This not only makes on-site operation time-consuming and labor-intensive but also requires stockpiling various specifications of water distribution pipes 9, increasing material consumption and construction costs. To address this deficiency, this embodiment is equipped with a water distribution pipe 9 whose length can be adaptively adjusted, allowing it to adapt synchronously to changes in the dimensions of the upper adjusting bracket 1 and the lower adjusting bracket 2.

[0033] like Figure 3 and Figure 4 As shown, the moisturizing and maintenance equipment includes a slide rod 115. The top end of the slide rod 115 is fixedly connected to the first rotating shaft 107 via a mounting bracket 108. A connecting rod 109 is rotatably provided at the bottom of the mounting bracket 108. A first mounting plate 110 is fixedly provided at the bottom of the connecting rod 109. The connecting rod 109 passes through the first mounting plate 110 and is fixedly connected to the slide rod 115. A plurality of winding assemblies 111 are slidably provided on the slide rod 115. A water distribution pipe 9 is wound on the winding assembly 111. Both ends of the water distribution pipe 9 extend out from the winding assembly 111, such as... Figure 6 As shown, a second mounting plate 116 is provided below the lowest winding assembly 111. The second mounting plate 116 is fixedly connected to the second rotating shaft on the lower adjusting bracket 2. The second mounting plate 116 is slidably engaged with the slide rod 115. Several sets of winding assemblies 111 are connected by folding assemblies.

[0034] like Figure 7 and Figure 8As shown, the folding assembly includes multiple sets of cross-hinged folding links, including end links 114 and multiple linkage links 113. The ends of each link are hinged to each other via pins to form a scissor-type telescopic linkage assembly. The multiple sets of links are arranged and hinged vertically in sequence, and each link can rotate relative to the hinge point. When the upper and lower supports undergo longitudinal displacement, the linkage links 113 and end links 114 simultaneously fold or unfold, thereby changing the vertical spacing between the winding assemblies 111. One set of hinge points of the linkage links 113 is located on the connecting platform 112 fixedly mounted on the winding assembly 111, and the other set of hinge points of the linkage links 113 is located outside the winding assembly 111, as shown below. Figure 4 and Figure 6 As shown, the uppermost end link 114 is rotatably connected to the first mounting plate 110, and the lowermost end link 114 is rotatably connected to the second mounting plate 116.

[0035] like Figure 9 The winding assembly 111 shown includes a first winding drum 11101, inside which a second winding drum 11102 is rotatably mounted. Both the first and second winding drums 11101 and 11102 have two sets of slots 11107 at corresponding positions. A through hole 11105 is provided at the middle position of both the first and second winding drums 11101 and 11102. A sliding rod 115 passes through the through hole 11105, allowing the first winding drum 11101 to slide up and down on the sliding rod 115. The second winding drum 11102 is not connected to the sliding rod 115 and can rotate relative to the first winding drum 11101. The second winding drum 11102 has a first arc-shaped partition 11103, a second arc-shaped partition 11104, and a third arc-shaped partition 11106. The first arc-shaped partition 11103... The second arc-shaped partition 11104 and the second arc-shaped partition 11104 are concentric arc-shaped structures, with the centers of their arc contours coinciding. The water distribution pipe 9 is wound in a spiral manner after being folded in half, coiled between the concentrically arranged first arc-shaped partition 11103 and second arc-shaped partition 11104. The folded portion is fixed to the first arc-shaped partition 11103, and the coiled spring accommodates it within the interlayer space formed by the third arc-shaped partition 11106 and the second arc-shaped partition 11104. The water distribution pipe 9 is continuously wound in multiple layers along the concentric arc paths of the two sets of arc-shaped partitions. Both ends of the water distribution pipe 9 exit from two slots 11107, as shown below. Figure 7 As shown, the water distribution pipe 9 at the outlet end is connected to the corresponding connector 8.

[0036] When the upper adjusting bracket 1 and the lower adjusting bracket 2 undergo longitudinal displacement, the linkage rod 113 and the end connecting rod 114 rotate synchronously around the hinge point, and the folding angle between each set of connecting rods changes synchronously. Relying on the folding and unfolding action of the scissor linkage, the corresponding water distribution pipe 9 is driven to move up, down and translate synchronously, thereby adaptively adjusting the spacing between adjacent water distribution pipes 9, so as to realize the synchronous expansion and contraction adjustment of the width of the spray pipeline according to the size of the maintenance area. The entire scissor linkage linkage structure has synchronous transmission and good action synchronization. There is no need to disassemble the pipeline separately. The overall width can be expanded and contracted by simply pushing and pulling the bracket, which can adapt to the spray range requirements of different reinforced walls.

[0037] like Figure 4 After the water distribution pipes 9 on the winding assembly 111 are pulled out from both ends, in order to prevent the water pipes inside the winding assembly 111 from connecting and storing water, thus increasing the overall weight of the equipment, this embodiment also provides two sets of clamping mechanisms to clamp the water pipes 9 at both ends, preventing the water pipes at both ends from connecting. The clamping mechanism includes two long clamping plates with adjustable spacing. The long clamping plates simultaneously clamp the water distribution pipes 9 of the micro nozzles 10 at the winding assembly 111. After the water distribution pipes 9 on the winding assembly 111 are stretched, the clamping mechanism is used to clamp the water distribution pipes 9 at both release ends of the winding assembly 111, preventing water from flowing in the water distribution pipes 9 at the winding point inside the winding assembly 111, reducing the overall load-bearing weight of the equipment. The two long clamping plates can be adjusted manually or by other means.

[0038] The working principle of the adaptively adjustable water distribution pipe 9: Figure 1 and 7 As shown, when the telescopic rods of the upper adjusting bracket 1 and the lower adjusting bracket 2 extend outward, the distance between the first support rod 3 and the second support rod 5 increases synchronously, and both ends of the water distribution pipe 9 are pulled outward and drawn out from the winding assembly 111, thus adapting to the overall width after the adjustment of the upper adjusting bracket 1 and the lower adjusting bracket 2; when the lower adjusting bracket 2 is pulled down, the folding assembly unfolds accordingly, synchronously adjusting the interval between each group of winding assemblies 111, causing multiple water distribution pipes 9 to unfold synchronously and equidistantly, so that each micro-sprayer 10 is evenly distributed within the wall curing area. It should be emphasized that the core improvement of this embodiment is as follows: the telescopic rod adjusts the distance between the first support rod 3 and the second support rod 5, and the water distribution pipe 9 can be pulled out from the winding assembly 111 to adapt to the horizontal width after the adjustment of the upper adjustment bracket 1 and the lower adjustment bracket 2. The length of the water distribution pipe 9 can be adaptively adjusted without the need to replace different specifications of pipes. When the lower adjustment bracket 2 is pulled down to unfold the folding assembly, the distance between each group of winding assemblies 111 is adjusted synchronously, driving multiple water distribution pipes 9 to extend synchronously and equidistantly. Relying on the synchronous telescopic adjustment of the water distribution pipes 9, the micro nozzles 10 are evenly distributed in the curing area. One set of devices can adapt to various sizes of reinforced walls, with uniform spraying and no curing dead corners, greatly simplifying the on-site pipe adjustment operation.

[0039] Example 4 A method for moisturizing and curing composite mortar involves using the aforementioned composite mortar moisturizing and curing equipment to spray moisturize and cure the reinforced wall layer. The shape and extension length of the upper adjustment bracket 1 and the lower adjustment bracket 2 are adjusted according to the size and shape of the reinforced wall surface to match various types of walls, including flat, curved, and right-angled walls. When the area to be cured is large, extension rods are connected to the ends of the first support rod 3 and the second support rod 5 to expand the overall spray coverage area of ​​the equipment. Then, an external water pipe is connected to the water inlet valve 13 to supply water. The water flows through the first pipe 7 and the connector 8 to the water distribution pipe 9, and is sprayed evenly throughout the entire area through the micro nozzles 10, continuously providing a stable moisturizing environment for the M30 composite mortar and avoiding cracking and sanding defects caused by uneven drying and wetting during curing.

[0040] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
