Description

Technical Field

[0001] The present invention relates to the field of building construction, and particularly relates to a shotcreting device and a shotcreting method for building construction. Background Art

[0002] In the prior art, wall plastering operations are basically mainly manual plastering. Workers hold plastering knives and smooth the mortar onto the wall bit by bit. This plastering method has low efficiency and high labor costs.

[0003] In view of the above situation, some automatic shotcreting devices have emerged in the industry. For example, as shown in patents with application numbers 202310484079.9, 202210865218.8, 202222266643.3, etc. These automatic shotcreting devices use high-pressure delivery pumps to spray mortar onto the wall to replace manual plastering operations, greatly improving the efficiency of plastering operations and reducing labor costs. However, the mortar sprayed onto the wall by these automatic shotcreting devices still needs to be manually smoothed later. The wall plastering operation still cannot be completely separated from manual work, and the efficiency of manual smoothing is inherently not high. This undoubtedly limits the improvement of the overall efficiency of wall plastering operations. The wall plastering operation still requires a lot of manpower, with high costs and low plastering efficiency.

[0004] Although there are also some mortar smoothing devices in the industry specifically used to replace manual smoothing of mortar on the wall, which truly realizes complete separation from manual plastering operations and improves the overall efficiency of wall plastering operations, using an automatic shotcreting device + mortar smoothing device in combination to complete the wall plastering operation undoubtedly consumes a large amount of electric energy and is not energy-saving. The comprehensive cost is not much lower than that of the wall plastering operation plan using manual smoothing + automatic shotcreting device. Summary of the Invention

[0050] The present invention provides a shotcreting device for building construction. The shotcreting device for building construction has a large shotcreting working surface, a fast shotcreting speed, high efficiency, and the width of the shotcreting working surface is adjustable, which can meet the shotcreting requirements of different walls 25. The shotcreting device is equipped with a smoothing hose 16, which can smooth the mortar on the wall 25 while spraying mortar onto the wall 25. There is no need to use an automatic shotcreting device + a mortar smoothing device to cooperate to complete the plastering operation on the wall 25. It has low power consumption, remarkable energy-saving effect, and there is no need for manual smoothing of the mortar on the wall 25, which improves the plastering operation efficiency of the wall 25 and reduces the construction cost.

[0051] Specifically, in an embodiment of the invention, as Figures 1-3 、 Figure 5 shown, the shotcreting device for building construction includes a slide rail 1 and a sliding box 2, a fixed box 3, and a first pushing and pulling device 4 provided on the slide rail 1. The sliding box 2 and the fixed box 3 are parallel to each other and are both horizontally arranged. The sliding box 2 is horizontally slidably connected to the slide rail 1, the fixed box 3 is fixedly connected to the slide rail 1, the first pushing and pulling device 4 is fixedly connected to the slide rail 1, and the movable end of the first pushing and pulling device 4 is connected to the sliding box 2, which is used to drive the sliding box 2 to horizontally slide along its own length direction on the slide rail 1 to adjust the distance between one end of the fixed box 3 away from the sliding box 2 in the length direction and one end of the sliding box 2 away from the fixed box 3 in the length direction, thereby adjusting the width of the shotcreting working surface to meet the shotcreting requirements of different-width walls 25 and always keeping the shotcreting efficiency maximized. It has rich functions and good practicability.

[0052] Specifically, when the width of the area of the wall 25 to be shotcreted is large, the width of the shotcreting working surface can be adjusted to the maximum, as Figures 1-3As shown, during the working process of the shotcreting equipment for building construction in this embodiment, it has the largest shotcreting working surface and the highest shotcreting efficiency. When the width of the wall surface 25 area to be shotcreted is not large, the distance between the end of the fixed box 3 away from the sliding box 2 in the length direction and the end of the sliding box 2 away from the fixed box 3 in the length direction can be appropriately shortened to adapt to walls of different widths, ensuring that the shotcreting equipment for building construction in this embodiment always performs shotcreting operations on the wall surface 25 with the highest shotcreting efficiency, which is conducive to reducing construction costs.

[0053] In this embodiment, as Figures 1-3 , Figure 5 shown, a plurality of shotcreting pipes 5 arranged in a straight line are equidistantly provided on the sliding box 2 and the fixed box 3 along their own length directions. A control valve 6 is provided on each shotcreting pipe 5. An inlet slurry pipe is also provided on the sliding box 2 and the fixed box 3. Preferably, the inlet slurry pipe is located on the side of the sliding box 2 and the fixed box 3 away from the shotcreting pipes 5. As Figure 1 shown, the inlet slurry pipe on the sliding box 2 is denoted as the first inlet slurry pipe 7, and a control valve 6 is also provided on the first inlet slurry pipe 7. The inlet slurry pipe on the fixed box 3 is denoted as the second inlet slurry pipe 8. As Figure 6 shown, the first inlet slurry pipe 7 and the second inlet slurry pipe 8 are connected to the slurry conveying pipe 9, and the slurry conveying pipe 9 is connected to a slurry pump. The slurry pump injects mortar into the sliding box 2 and the fixed box 3 through the slurry conveying pipe 9. Under the action of the slurry injection pressure, the mortar in the sliding box 2 and the fixed box 3 sprays out from the shotcreting pipes 5. When the plurality of shotcreting pipes 5 arranged in a straight line are aligned with the wall surface 25, the plurality of shotcreting pipes 5 arranged in a straight line can spray mortar on the wall surface 25. Then, the shotcreting equipment for building construction in this embodiment can be moved up or down along the wall surface 25 to complete the shotcreting construction operation of the entire wall surface 25.

[0054] Furthermore, in order to ensure that the thickness of the mortar sprayed on the wall surface 25 when the shotcreting equipment for building construction in this embodiment moves up or down along the wall surface 25 is uniform everywhere, the speed at which the shotcreting equipment for building construction in this embodiment moves up or down along the wall surface 25 should always be kept constant, and the shotcreting pipes 5 in the overlapping area of the sliding box 2 and the fixed box 3 are closed and do not spray mortar. That is, the control valves 6 on the sliding box 2 that are not directly above or directly below the fixed box 3 are opened, so that this part of the shotcreting pipes 5 spray mortar on the wall surface 25, and the control valves 6 on the sliding box 2 that are directly above or directly below the fixed box 3 are closed, so that this part of the shotcreting pipes 5 do not spray mortar on the wall surface 25. In this way, only one shotcreting pipe 5 sprays mortar in each column area on the wall surface 25, and there will be no situation where the upper and lower two shotcreting pipes 5 spray mortar towards one column area, ensuring that the thickness of the mortar sprayed on the wall surface 25 when the shotcreting equipment for building construction in this embodiment moves up or down along the wall surface 25 is uniform everywhere, which is conducive to improving the quality of the plastering operation on the wall surface 25.

[0055] Further, to facilitate the control of the opening and closing of multiple control valves 6, as Figure 5 shown, a displacement sensor 13 is provided on the push-pull device 1. The displacement sensor 13 is used to detect the position of the sliding box 2 relative to the fixed box 3, so as to control the opening of the control valve 6 on the sliding box 2 that is not directly above or below the fixed box 3 in real time according to the detection result. Or rather, to control the closing of the control valve 6 on the sliding box 2 that is directly above or below the fixed box 3 in real time according to the detection result, ensuring that only one spraying pipe 5 sprays mortar in each column area on the wall surface 25, and preventing the situation where two upper and lower spraying pipes 5 spray mortar towards one column area, ensuring that the thickness of the mortar sprayed on the wall surface 25 by the spraying equipment for building construction in this embodiment when moving up or down along the wall surface 25 is uniform everywhere, which is beneficial to improving the quality of the plastering operation on the wall surface 25; specifically, the displacement sensor 13 transmits the detection data to the processor, and the processor analyzes and processes the data to obtain the position of the sliding box 2 relative to the fixed box 3, and then controls the closing of the control valve 6 on the sliding box 2 that is directly above or below the fixed box 3, and the opening of other control valves 6. When the sliding box 2 slides on the slide rail 1 subsequently, the processor can dynamically adjust the number of open control valves 6 and closed control valves 6 in real time according to the detection data of the displacement sensor 13, ensuring that only one spraying pipe 5 sprays mortar in each column area on the wall surface 25, and preventing the situation where two upper and lower spraying pipes 5 spray mortar towards one column area, saving the trouble of manually adjusting the opening and closing of the control valve 6, saving time and effort, and having good practicability.

[0056] In this embodiment, as Figures 1-3 、 Figure 5 shown, a smoothing hose 16 is suspended directly below the sliding box 2 and the fixed box 3. Two ends of the smoothing hose 16 are respectively connected to one end of the fixed box 3 far away from the sliding box 2 in the length direction and one end of the sliding box 2 far away from the fixed box 3 in the length direction. With this design, the smoothing hose 16 is parallel to the vertical plane passing through the length directions of the sliding box 2 and the fixed box 3, that is, the smoothing hose 16 can be parallel to the wall surface 25 to be sprayed with mortar. Subsequently, the mortar sprayed on the wall surface 25 by the spraying equipment for building construction in this embodiment when moving up or down along the wall surface 25 can be smoothed by the smoothing hose 16, realizing spraying mortar on the wall surface 25 while smoothing the mortar on the wall surface 25. There is no need to use an automatic spraying equipment + mortar smoothing equipment to cooperate to complete the plastering operation on the wall surface 25, with low power consumption and significant energy-saving effect. Moreover, there is no need to manually smooth the mortar on the wall surface 25, improving the efficiency of the plastering operation on the wall surface 25 and reducing the construction cost.

[0057] The shotcreting equipment for building construction in this embodiment adopts a plurality of shotcreting pipes 5 arranged in a straight line on the sliding box 2 and the fixed box 3 to obtain a higher shotcreting operation efficiency. The sliding box 2 can slide relative to the fixed box 3 to adjust the width of the shotcreting operation surface, so as to meet the shotcreting requirements of walls 25 with different widths and always keep the shotcreting efficiency maximized, which is very beneficial to reducing the construction cost. In addition, a smoothing hose 16 is connected to one end of the fixed box 3 far away from the sliding box 2 in the length direction and one end of the sliding box 2 far away from the fixed box 3 in the length direction. The smoothing hose 16 is located directly below the sliding box 2 and the fixed box 3, and the design parallel to the vertical plane passing through the length directions of the sliding box 2 and the fixed box 3 enables the shotcreting equipment for building construction in this embodiment to drive the smoothing hose 16 to move up or down along the wall 25 synchronously while moving up or down along the wall 25 to spray mortar on the wall 25, so as to smooth the mortar on the wall 25. The smoothing hose 16 is soft in texture and does not affect the sliding of the sliding box 2 relative to the fixed box 3 to adjust the width of the shotcreting operation surface. Therefore, it can realize spraying mortar on the wall 25 while smoothing the mortar on the wall 25, without the need to use an automatic shotcreting equipment + a mortar smoothing equipment to cooperate with each other to complete the plastering operation of the wall 25, with low power consumption and remarkable energy-saving effect. Moreover, there is no need for manual smoothing of the mortar on the wall 25, which improves the plastering operation efficiency of the wall 25 and reduces the construction cost.

[0058] In this embodiment, as Figures 1-3 、 Figure 5 shown, a wheel frame 10 is provided at one end of the fixed box 3 far away from the sliding box 2 in the length direction and one end of the sliding box 2 far away from the fixed box 3 in the length direction. A plurality of rollers 11 are arranged on the wheel frame 10 in the vertical direction. With such a design, by driving the shotcreting equipment for building construction in this embodiment to move up or down along the wall 25 by rolling a plurality of rollers 11 closely against the wall 25, it can ensure that the shotcreting equipment for building construction in this embodiment moves up or down along the wall 25 stably, and then ensure that the distances from the shotcreting pipes 5 and the smoothing hose 16 to the wall 25 can always remain constant, ensuring high-quality mortar smoothing and good smoothing effect.

[0059] Furthermore, as Figure 3As shown, a rotational speed sensor 12 is provided on the roller 11. The rotational speed sensor 12 is used to detect the rotational speed of the roller 11, so as to regulate the speed of the shotcreting equipment for building construction in this embodiment moving upward or downward along the wall surface 25, and make the speed of the shotcreting equipment for building construction in this embodiment moving upward or downward along the wall surface 25 always remain uniform. Specifically, the rotational speed sensor 12 transmits the detected data to the processor, and after being processed by the processor, the rotational speed information is displayed on the touch screen 24. The construction workers flexibly adjust the speed of the shotcreting equipment for building construction in this embodiment moving upward or downward along the wall surface 25 according to the display data on the touch screen 24, so that the speed of the shotcreting equipment for building construction in this embodiment moving upward or downward along the wall surface 25 always remains uniform, ensuring that the thickness of the mortar sprayed on the wall surface 25 when the shotcreting equipment for building construction in this embodiment moves upward or downward along the wall surface 25 is uniform everywhere, which is beneficial to improving the quality of the plastering operation on the wall surface 25.

[0060] Specifically, when the shotcreting equipment for building construction in this embodiment moves upward or downward along the wall surface 25 by manual driving, such as Figure 6 As shown, the shotcreting equipment for building construction in this embodiment further has a hand-held rod 23. The hand-held rod 23 is connected to the slide rail 1. The worker holds the hand-held rod 23 to drive the shotcreting equipment for building construction in this embodiment to move upward or downward along the wall surface 25. At this time, the touch screen 24 is arranged on the hand-held rod 23. The construction workers flexibly adjust the speed of the shotcreting equipment for building construction in this embodiment moving upward or downward along the wall surface 25 according to the display data on the touch screen 24, so that the speed of the shotcreting equipment for building construction in this embodiment moving upward or downward along the wall surface 25 always remains uniform, ensuring that the thickness of the mortar sprayed on the wall surface 25 when the shotcreting equipment for building construction in this embodiment moves upward or downward along the wall surface 25 is uniform everywhere, which is beneficial to improving the quality of the plastering operation on the wall surface 25.

[0061] If the shotcreting equipment for building construction in this embodiment moves upward or downward along the wall surface 25 by being driven by a crane, that is, the slide rail 1 is connected to the boom of the crane, and the shotcreting equipment for building construction in this embodiment is driven to move upward or downward along the wall surface 25 by the boom of the crane, then the touch screen 24 is arranged on the crane, such as in the cab of the crane. The construction workers flexibly adjust the speed of the shotcreting equipment for building construction in this embodiment moving upward or downward along the wall surface 25 according to the display data on the touch screen 24, so that the speed of the shotcreting equipment for building construction in this embodiment moving upward or downward along the wall surface 25 always remains uniform, ensuring that the thickness of the mortar sprayed on the wall surface 25 when the shotcreting equipment for building construction in this embodiment moves upward or downward along the wall surface 25 is uniform everywhere, which is beneficial to improving the quality of the plastering operation on the wall surface 25.

[0062] Of course, in other embodiments, the detection data of the speed sensor 12 can also be transmitted to the controller of the crane, and the controller controls the crane to automatically adjust the speed of the construction spraying equipment of this embodiment moving upward or downward along the wall 25 according to the detection data, instead of manual control, thereby realizing closed-loop feedback fully automatic control, with a high degree of intelligence and automation, which is conducive to further reducing construction costs.

[0063] Furthermore, in this embodiment, if Figure 1 and Figure 5 As shown, a pressure sensor 20 is provided on the side of the slide rail 1 away from the spraying pipe 5, and the pressure sensor 20 is connected to a rotating motor 21, which drives the slide rail 1 to rotate around a horizontal axis on a vertical plane in the length direction of the sliding box 2 and the fixed box 3, thereby driving the smoothing hose 16 from Figure 1 The position shown is rotated 180 degrees to just above the sliding box 2 and the fixed box 3, so that the smoothing hose 16 can perform smoothing operations during the upward or downward movement of the spraying equipment for construction of this embodiment along the wall 25. The rotating motor 21 is connected to the hand-held rod 23 or the lifting arm of the crane, and the spraying equipment for construction of this embodiment is driven to move upward or downward along the wall 25 by holding the hand-held rod 23 or controlling the lifting arm of the crane to drive the spraying equipment for construction of this embodiment to move upward or downward along the wall 25. The touch screen 24 is arranged on the hand-held rod 23, which is convenient for observing the data on the touch screen 24 and operating the touch screen 24 to control the rotating motor 21, the push-pull device 1 4, and the push-pull device 2 14, lifting device 15, push-pull device 18 action; when the roller 11 is pushed by the hand-held rod 23 or the crane arm to contact the wall 25, the pressure sensor 20 can detect the pressure of the hand-held rod 23 or the crane arm on the slide rail 1, and the pressure data is processed by the processor and displayed on the touch screen 24, so that the worker holding the hand-held rod 23 or the crane arm can adjust the pressure on the slide rail 1, so that the pressure of the hand-held rod 23 or the crane arm on the slide rail 1 is always constant during the process of the spraying equipment for construction of this embodiment moving upward or downward along the wall 25. This design ensures that the distance from the spraying pipe 5 and the smoothing hose 16 to the wall 25 can always remain constant, ensuring high quality and good smoothing effect of the mortar.

[0064] Preferably, the rotating motor 21 is hinged to the hand-held rod 23 through a hinge joint 22. This design facilitates the control of the vertical up and down movement of the spraying equipment for construction along the wall 25, and ensures that the distance from the spraying pipe 5 and the smoothing hose 16 to the wall 25 can always remain constant, ensuring high quality and good smoothing effect of the mortar.

[0065] Further, such as Figure 1As shown, a spirit level 19 is provided on the slide rail 1, the fixed box 3 or the sliding box 2. The spirit level 19 is used to detect whether the slide rail 1, the fixed box 3 or the sliding box 2 rotates to the horizontal state driven by the rotating motor 21. When the slide rail 1, the fixed box 3 or the sliding box 2 is in the horizontal state, the width of the spraying surface is the largest, which can fully exploit the spraying efficiency of the spraying equipment for building construction.

[0066] In this embodiment, as Figures 1-3 , Figure 5 shown, a second pushing and pulling device 14 is provided on the wheel frame 10. The second pushing and pulling device 14 is connected to the lifting device 15. The second pushing and pulling device 14 drives the lifting device 15 to move in a direction perpendicular to the vertical plane passing through the length direction of the sliding box 2 and the fixed box 3. With this design, the distances from the spraying pipe 5 and the smoothing hose 16 to the wall surface 25 can be flexibly adjusted according to specific spraying operation requirements. For example, when spraying ash mortar, the distances from the spraying pipe 5 and the smoothing hose 16 to the wall surface 25 are larger, and when spraying latex paint, the distances from the spraying pipe 5 and the smoothing hose 16 to the wall surface 25 are smaller. The setting of the second pushing and pulling device 14 enables the spraying equipment for building construction in this embodiment to flexibly adjust the distances from the spraying pipe 5 and the smoothing hose 16 to the wall surface 25 according to specific spraying operations, expanding the application range of the spraying equipment for building construction in this embodiment and having good practicability.

[0067] In this embodiment, as Figures 1-3 , Figure 5 shown, the lifting device 15 is connected to the end of the smoothing hose 16. The lifting device 15 drives the smoothing hose 16 to lift and lower. With this design, when the smoothing hose 16 is driven by the rotating motor 21 to the directly above the slide rail 1, the fixed box 3 and the sliding box 2, in order to prevent the middle part of the smoothing hose 16 from sagging and touching the slide rail 1, the fixed box 3 or the sliding box 2, which may cause the smoothing hose 16 to no longer be parallel to the wall surface 25 and affect the smoothing operation quality, the lifting device 15 can lift the smoothing hose 16 to prevent the middle part of the smoothing hose 16 from sagging and touching the slide rail 1, the fixed box 3 or the sliding box 2.

[0068] In addition, when the spraying equipment for building construction in this embodiment moves vertically upward along the wall surface 25, a small area that cannot be smoothed by the smoothing hose 16 below the smoothing hose 16, and when the spraying equipment for building construction moves vertically downward along the wall surface 25, a small area that cannot be smoothed by the smoothing hose 16 above the smoothing hose 16 can be smoothed manually.

[0069] In this embodiment, further, as Figures 1-3 , Figure 5As shown, a third pushing and pulling device 18 is further provided on the sliding rail 1. The pushing and pulling direction of the third pushing and pulling device 18 is parallel to that of the second pushing and pulling device 14. The third pushing and pulling device 18 is connected to a vertically arranged L-shaped stop rod 17. The vertical rod of the L-shaped stop rod 17 is attached to the side of the plastering hose 16 facing away from the wall surface 25, and is used to block the plastering hose 16 from swinging away from the wall surface 25, ensuring that the plastering hose 16 always remains parallel to the wall surface 25 and guaranteeing the plastering quality. The horizontal rod of the L-shaped stop rod 17 is used to block the middle part of the plastering hose 16 from sagging under its own gravity and contacting the sliding box 2, the fixed box 3, the sliding rail 1, the spraying pipe 5, and the control valve 6 when the plastering hose 16 rotates to the directly above the sliding box 2 and the fixed box 3, which may affect the plastering quality.

[0070] In this embodiment, as Figure 1 and Figure 4 shown, the plastering hose 16 includes a hose body 161 and a thin metal tube 162 coaxially sleeved outside the hose body 161. The hose body 161 can be made of rubber to ensure that the hose body 161 has a certain softness, which is convenient for freely bending according to the width of the spraying operation surface. The thin metal tube 162 is used to contact the mortar, then plaster the mortar, and obtain a good plastering effect. The thin metal tube 162 is soft in texture and can be bent at will without affecting the bending of the hose body 161. The two ends of the hose body 161 are sealed by plug caps 163. The plug caps 163 are detachable. Such a design facilitates injecting heavy fluid into the hose body 161. The plug caps 163 are connected to a mounting shaft 165. The mounting shaft 165 is installed on a shaft seat 166. The shaft seat 166 is connected to a lifting device 15. The plastering hose 16 can either be fixedly connected to the lifting device 15, so that the plastering hose 16 slides along the wall surface 25 to plaster the mortar, or the plastering hose 16 can be rotatably connected to the lifting device 15, and the plastering hose 16 rolls along the wall surface 25 to plaster the mortar. Further, heavy fluid is provided inside the hose body 161 to increase the weight of the middle part of the plastering hose 16, so as to reduce the swing, and then enhance the plastering stability of the plastering hose 16, reduce the swing of the plastering hose 16 during the process of plastering the mortar, enable the plastering hose 16 to move up and down smoothly to plaster the mortar, and improve the plastering quality. Specifically, the heavy fluid is water or small heavy balls 164, as Figure 4 shown.

The width of the spraying operation is the distance between the two wheel brackets 10. Such a design can maximize the construction efficiency of the spraying equipment for building construction, improve the spraying and plastering operation efficiency as much as possible, and reduce the construction cost. The specific adjustment operation can be achieved by controlling the operation of the first push-pull device 4;

[0073] S2. Close the control valve 6 on the sliding box 2 that is directly above or below the fixed box 3, open the remaining control valves 6 on the sliding box 2, and open all the control valves 6 on the fixed box 3 to ensure that only one spraying pipe 5 sprays on each column area of the wall surface 25, and there will be no situation where the upper and lower two spraying pipes 5 spray on one column area, ensuring that the thickness of the mortar sprayed on the wall surface 25 by the spraying equipment for building construction in this embodiment when moving up or down along the wall surface 25 is uniform everywhere, which is beneficial to improving the quality of the plastering operation on the wall surface 25;

[0074] S3. Make the roller 11 contact with the wall surface 25, and control the second push-pull device 14 and the third push-pull device 18 according to the specific spraying operation situation to adjust the distance between the smoothing hose 16 and the wall surface 25 to meet the requirements for the thickness of the slurry smoothing on the wall surface 25, expanding the application range of the spraying equipment for building construction in this embodiment and having good practicability;

[0075] S4. Connect the slurry delivery pipe 9 to the slurry inlet pipe, and use the hand-held rod 23 or the lifting arm to move the sliding box 2 and the fixed box 3 vertically upward along the wall surface 25. At the same time, the spraying pipe 5 is kept perpendicular to the wall surface 25. During the process of the sliding box 2 and the fixed box 3 moving vertically upward along the wall surface 25, the pressure of the hand-held rod 23 or the lifting arm on the slide rail 1 is constant, ensuring that the roller 11 always rolls closely against the wall surface 25;

[0076] S5. Start the slurry pump to inject mortar into the sliding box 2 and the fixed box 3, and the mortar with a certain pressure is sprayed out from the spraying pipe 5 and adheres to the wall surface 25;

[0077] S6. The smoothing hose 16 moves vertically upward along the wall surface 25 to smooth the mortar adhering to the wall surface 25.

[0078] In this embodiment, the spraying method for building construction further includes:

[0079] S7. Control the rotating motor 21 to drive the slide rail 1 to rotate and drive the smoothing hose 16 to rotate to directly above the sliding box 2 and the fixed box 3, preferably at a rotation angle of 180 degrees;

[0080] S8. Control the lifting device 15 to adjust the height of the smoothing hose 16 to prevent the smoothing hose 16 from contacting the sliding box 2, the fixed box 3, the slide rail 1, the spraying pipe 5, and the control valve 6 under the action of its own gravity;

[0081] S9. Use the handheld rod 23 or the lifting arm to move the sliding box 2 and the fixed box 3 vertically downward along the wall surface 25. At the same time, keep the spraying pipe 5 perpendicular to the wall surface 25. During the process of the sliding box 2 and the fixed box 3 moving vertically downward along the wall surface 25, the pressure of the handheld rod 23 or the lifting arm on the slide rail 1 is constant, ensuring that the rollers 11 always roll closely against the wall surface 25;

[0082] S10. Start the slurry pump to inject mortar into the sliding box 2 and the fixed box 3. The mortar with a certain pressure is ejected from the spraying pipe 5 and adheres to the wall surface 25;

[0083] S11. Move the smoothing hose 16 vertically downward along the wall surface 25 to smooth the mortar adhering to the wall surface 25.

[0084] In this embodiment, the spraying method for building construction further includes:

[0085] S12. After the spraying equipment for building construction in this embodiment moves vertically downward along the wall surface 25 to the lowest point, control the rotation motor 21 to drive the slide rail 1 to rotate, driving the smoothing hose 16 to rotate to directly below the sliding box 2 and the fixed box 3. Preferably, the rotation angle is 180 degrees, and then repeat S1 - S11.

[0086] In this embodiment, before controlling the rotation motor 21 to drive the slide rail 1 to rotate and drive the smoothing hose 16 to rotate, first separate the spraying equipment for building construction from the wall surface 25. After the smoothing hose 16 rotates to the in-place position, then restore the contact between the spraying equipment for building construction and the wall surface 25.
