Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a linear pouring construction equipment and method for building joint mortar. Background Technology

[0002] During construction, some building foundations have long joints. When mortar is applied to these joints, workers manually pour large amounts of mortar along the joints. This results in a large amount of mortar being spread on the outer edge of the joint area, causing not only a significant waste of mortar but also requiring considerable manpower to clean up the "protruding" mortar during subsequent construction.

[0003] To reduce excess mortar during joint grouting, workers need to be meticulous and slow in injecting mortar into the joints to ensure that the amount of mortar at the joints is reasonable. However, this "slow and steady wins the race" approach also affects the overall construction efficiency of the workers.

[0004] In summary, during the mortar injection process in the joint area, rapid mortar pouring can easily lead to excessive mortar volume, while meticulous pouring of the joint area can significantly impact construction efficiency. Effectively resolving the contradiction between mortar pouring volume and construction efficiency during joint pouring has become a challenging problem. Summary of the Invention

[0005] This invention provides a linear pouring equipment and method for building joint mortar, thereby ensuring that the mortar can be injected into the joint area more efficiently, and significantly reducing the amount of mortar remaining outside the joint, reducing or even eliminating the need for additional cleaning procedures.

An air pump that supplies air to the first air inlet pipe and the second air inlet pipe, as well as an air pressure regulating device for adjusting the air pressure in the upper air chamber, are fixedly installed on the bottom side of the mortar supply tank.

[0010] As a preferred technical solution of the construction equipment of the present invention: the guide pipe is provided with a connecting component that is fixedly connected to the cover, the cover is fixedly installed with an upper air nozzle, the upper air nozzle is connected to the air pressure regulating device through an air pipe, and the upper air nozzle is connected to the upper air chamber.

[0012] As a preferred technical solution of the construction equipment of the present invention: the bottom of the inverted cone of the bottom box is provided with a bottom opening, the side wall of the bottom opening ring is provided with a threaded structure, the outer side of the seam ring is provided with a threaded part, and the threaded part of the seam ring is installed in conjunction with the threaded structure of the side wall of the bottom opening ring.

[0013] As a preferred technical solution of the construction equipment of the present invention: the joint ring is provided with an inner opening that runs through the top and bottom, the upper part of the inner opening is a lower conical wide opening that communicates with the bottom of the mortar cavity, and the upper part of the outer ring surface of the joint ring is provided with a mating conical ring surface that cooperates with the inverted cone.

[0014] As a preferred technical solution of the construction equipment of the present invention: the guide pipe is provided with a vertical main channel communicating with the mortar supply tank. The guide pipe is provided with an outlet side channel communicating with the mortar chamber, and the outlet side channel is connected to the bottom of the vertical main channel. The horizontal position of the opening of the outlet side channel facing the mortar chamber is lower than the horizontal position of the lowest point of the vertical stroke range of the piston ring plate.

[0015] As a preferred technical solution of the construction equipment of the present invention: the horizontal position of the lowest point of the air guide curved surface is lower than the horizontal position of the bottom side of the inverted cone and the seam ring.

[0016] As a preferred technical solution of the construction equipment of the present invention: a first air inlet pipe and a second air inlet pipe are fixedly installed on the outer ring side of the bottom box, one set of lower air outlets is connected to the first air inlet pipe, and the other set of lower air outlets is connected to the second air inlet pipe.

[0017] As a preferred technical solution of the construction equipment of the present invention: the bottom side of the outer ring body is also equipped with a ring of multiple roller structures, and the horizontal position of the roller structure is lower than the horizontal position of the bottom side of the inverted cone and the joint ring.

[0018] This invention provides a linearized pouring method for building joint mortar, comprising the following steps:

[0019] S1. Move the mortar supply tank above the joint area, turn on the laser, and the laser will shine downwards in a fan shape. Adjust the position of the mortar supply tank to ensure that the laser beam is aimed at the joint area.

[0020] S2. Open the valve of the mortar supply tank guide pipe to inject mortar. The mortar in the mortar supply tank flows downward through the guide pipe into the mortar chamber of the bottom box component. The mortar in the mortar chamber flows downward from the joint ring component into the joint area.

[0021] S3. When either the first distance sensor or the second distance sensor detects that the distance caused by the mortar overflow has decreased, the mortar supply tank begins to move, ensuring that the laser beam shone downwards from the laser device is aligned with the joint during the movement.

[0022] S4. At the same time, the air pump and air pressure regulating device are started. The air pump independently supplies air to the first air inlet pipe and the second air inlet pipe through the built-in multi-way valve. The airflow from the lower air outlet of the first air inlet pipe and the second air inlet pipe moves along the air guide surface and blows air onto the mortar in the horizontal gap. The mortar overflowing from the horizontal gap moves towards the joint.

[0023] S5. During the movement of the mortar supply tank:

[0024] S5.1. When the first distance sensor detects a decrease in distance due to mortar overflow, the air pump increases the airflow rate to the first air intake pipe until the distance information detected by the first distance sensor returns to normal, at which point the air pump reduces the airflow rate to the first air intake pipe to the normal rate.

[0025] S5.2. When the second distance sensor detects a decrease in distance due to mortar overflow, the air pump increases the airflow rate to the second air intake pipe until the distance information detected by the second distance sensor returns to normal, at which point the air pump reduces the airflow rate to the second air intake pipe to the normal rate.

[0026] S5.3. When the first or second distance sensor detects a decrease in distance due to mortar overflow, the air pressure regulating device reduces the air pressure in the upper air chamber to P. c -ΔP m .

[0027] Among them, P c ΔP is the reference air pressure value when the mortar on both sides of the horizontal gap has not overflowed.m This is a reference unit for reducing air pressure in the upper air chamber.

[0028] S5.4. When the first distance sensor and the second distance sensor simultaneously detect a decrease in distance due to mortar overflow, the air pressure regulating device reduces the air pressure in the upper air chamber to P. c -2ΔP m .

[0029] S6. When the mortar supply tank moves 20-30cm before the end of the joint, close the valve of the mortar supply tank guide pipe to inject mortar. The mortar supply tank continues to move towards the end of the joint at a constant speed. The air pump continues to supply air to the first air inlet pipe and the second air inlet pipe. At the same time, the air pressure regulating device gradually increases the air pressure in the upper air chamber to gradually discharge the remaining mortar in the mortar chamber and inject it into the remaining section of the joint area. Then, turn off the air pump and the air pressure regulating device.

[0030] Compared with existing technologies, the beneficial effects of this invention are:

[0031] This invention utilizes a laser device in the mortar supply tank to provide precise "navigation" for pouring mortar into the joint. When injecting mortar into the joint area, an inverted cone and a joint ring are used to create a non-contact horizontal gap between the mortar and the building substrate, preventing friction. First and second distance sensors monitor whether mortar overflows from either side of the horizontal gap. An air pump controls the airflow rate of the first and second air inlets in real time, applying "inward" air pressure to the mortar in the horizontal gap. Simultaneously, an air pressure regulating device adjusts the downward pressure of the piston ring plate on the mortar in the mortar chamber, ensuring efficient mortar injection into the joint area and significantly reducing the amount of mortar remaining outside the joint, thus reducing or eliminating the need for subsequent cleaning procedures.

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0041] The linearized pouring equipment and method for building joint mortar of this invention are mainly used to solve the problems of mortar waste and low construction efficiency during joint mortar pouring in building construction. The following details its technical content, the role and significance of its main technical points from the aspects of equipment structure and construction method.

[0042] Example 1: This invention designs a linearized pouring construction device for building joint mortar, the specific structure of which is as follows:

[0043] Mortar supply tank 2: combined Figure 1 , Figure 7 The bottom side is equipped with two sets of walking frames 201, and the bottom of the walking frames 201 is equipped with walking wheels 202 for easy movement of the equipment. A hand lever 203 can also be installed (if an automatic walking mechanism is used, the hand lever assists in controlling the direction).

[0044] Guide tube 3: Combined Figure 1 , Figure 2 , Figure 3The device includes a connecting component 301 fixedly connected to the cover 401. It has an internal vertical main channel 302 communicating with the mortar supply tank 2, and multiple outlet side channels 303 at the bottom communicating with the mortar cavity 4031b. The outlet side channels 303 are connected to the bottom of the vertical main channel 302, and are inclined, with their openings facing the mortar cavity 4031b lower than the lowest point of the piston ring plate 402's vertical stroke range. The vertical main channel 302 guides the mortar from the mortar supply tank 2 to the outlet side channels 303. The outlet side channels 303 ensure that the mortar can smoothly enter the mortar cavity 4031b, and their opening positions are designed to prevent the piston ring plate 402 from blocking the mortar from entering.

[0045] The pressurized casting assembly 4 includes a cover 401, a piston ring plate 402, a bottom box 403, and a joint ring 404, etc., with the specific structure as follows:

[0046] 401 Cap: Combination Figure 2 , Figure 3 , Figure 6 It is fixedly installed on the upper side of the base box 403 and has an upper air nozzle 4011. The upper air nozzle 4011 is connected to the air pressure regulating device 7 and communicates with the upper air chamber 4031a through an air pipe. Its function is to seal the upper side of the base box 403 and, in conjunction with the air pressure regulating device 7, regulate the air pressure of the upper air chamber 4031a. The significance is to provide a channel for air pressure regulation, ensuring that the air pressure regulating device 7 can effectively act on the upper air chamber 4031a, thereby controlling the downward pressure intensity of the piston ring plate 402 on the mortar.

[0047] Piston ring plate 402: Combination Figure 2 , Figure 3 , Figure 4 , Figure 6 An inner piston ring 4021, which slides within the outer ring of the guide pipe 3, and an outer piston ring 4022, which slides within the inner cavity 4031 of the base box 403, are movably mounted around the guide pipe 3. The inner cavity 4031 of the base box 403 is divided into an upper air chamber 4031a and a mortar chamber 4031b by the piston ring plate 402. The piston ring plate 402 can move up and down under the air pressure of the upper air chamber 4031a, thereby applying pressure to the mortar in the mortar chamber 4031b and controlling the pouring speed and pressure of the mortar. The inner and outer piston rings ensure the sealing between the piston ring plate 402 and the guide pipe 3 and the base box 403, preventing mortar leakage and air leakage between the air chambers.

[0048] Bottom box component 403: such as Figure 2 , Figure 3 , Figure 4 , Figure 6The structure comprises an inner cavity 4031, an inverted cone 4032, and an outer ring 4034. The inverted cone 4032 is located below the mortar cavity 4031b, with a bottom opening 4033. The bottom opening 4033 has a threaded structure on its sidewall. The outer ring 4034 is located around the inverted cone 4032, with a ring of multiple roller structures 4038 on its bottom side. Its inner side has two sets of lower air outlets 4036 with a phase angle difference of π, and a guide surface 4039 with its lower end bent towards the seam ring 404. A first air inlet pipe 4035a and a second air inlet pipe 4035b are fixedly installed on the outer ring side. A first distance sensor 4037a and a second distance sensor 4037b with a phase angle difference of π are embedded in the bottom outer side of the inverted cone 4032. A horizontal gap 8 is formed between the bottom sides of the inverted cone 4032 and the seam ring 404 and the building base 1. The roller structure 4038 supports the equipment, ensuring that the inverted cone 4032 and the joint ring 404 do not contact the building base 1, thus avoiding friction. The lower air outlet 4036, the air guide curved surface 4039, the first air inlet pipe 4035a, and the second air inlet pipe 4035b, in conjunction with the air pump 6, can apply "inward" air pressure to the mortar in the transverse horizontal gap 8, preventing mortar overflow. The first distance sensor 4037a and the second distance sensor 4037b monitor whether mortar overflows from both sides of the transverse horizontal gap 8, providing feedback for the operation of the air pump 6 and the air pressure regulating device 7. This achieves precise control of the mortar pouring process, reducing mortar waste and subsequent cleaning work.

[0049] 404 threaded ring: such as Figure 2 , Figure 3 , Figure 4 , Figure 5 The outer ring has a threaded portion 4043 on its side, which is threaded to fit the bottom opening 4033 of the inverted cone 4032 of the base box 403. It also has an inner opening 4041 that extends vertically through the base. The upper part of the inner opening 4041 is a lower conical wide opening 4042 that communicates with the bottom of the mortar cavity 4031b. A mating conical ring surface 4044 that mates with the inverted cone 4032 is provided on the upper part of the outer ring surface. The joint ring 404 guides the mortar into the joint 101 area. Its special structural design ensures that the mortar can flow smoothly and concentrate at the joint, improving the mortar pouring effect and allowing the mortar to be accurately injected into the joint, thus improving the quality of the joint filling.

[0050] Laser device 5: such as Figure 1 , Figure 7 It is positioned on the side of the mortar supply tank 2 in the direction of travel, emitting a visible laser vertically downwards, combined with... Figure 2The laser 5 shines vertically downwards in a direction coplanar with the vertical axis of the joint ring 404. This provides precise "navigation" for the equipment to move towards the joint for pouring, ensuring that the joint ring 404 remains aligned with the joint 101 area during the equipment's movement, thus improving construction accuracy. This ensures the precision of the mortar pouring position and avoids waste and construction quality problems caused by mortar pouring deviations.

[0051] Air pump 6: such as Figure 1 , Figure 6 It is fixedly configured on the bottom side of the mortar supply tank 2, supplying air to the first air inlet pipe 4035a and the second air inlet pipe 4035b. By adjusting the airflow rate, in conjunction with the lower air outlet 4036 and the air guide surface 4039, the mortar in the transverse horizontal gap 8 is subjected to "inward" air pressure compression, reducing mortar overflow. The significance lies in real-time control of the mortar flow range and improving the utilization rate of mortar.

[0052] Air pressure regulating device 7: such as Figure 1 , Figure 2 , Figure 6 Fixedly mounted on the bottom side of the mortar supply tank 2, it is used to adjust the air pressure in the upper air chamber 4031a. Based on the monitoring results of the first distance sensor 4037a and the second distance sensor 4037b, the downward pressure of the piston ring plate 402 on the mortar in the mortar chamber 4031b is adjusted in real time to ensure that the mortar can be efficiently injected into the joint area. The significance lies in achieving dynamic adjustment of the mortar pouring pressure, adapting to different construction conditions, and improving construction efficiency and quality.

[0053] Example 2: This invention designs a linearized pouring method for building joint mortar, the specific construction method is as follows:

[0054] First, move the mortar supply tank 2 above the joint 101 area, turn on the laser device 5, and the laser device 5 will irradiate downwards in a fan shape. Adjust the position of the mortar supply tank 2 to ensure that the laser irradiated by the laser device 5 is aimed at the joint 101 area.

[0055] Then, open the valve of the mortar supply tank 2 to inject mortar into the guide pipe 3. The mortar in the mortar supply tank 2 flows downward through the guide pipe 3 into the mortar chamber 4031b of the bottom box 403. The mortar in the mortar chamber 4031b flows downward from the joint ring 404 into the joint 101 area.

[0056] When either the first distance sensor 4037a or the second distance sensor 4037b detects that the distance caused by the mortar overflow has decreased, the joint 101 area at the initial position has been filled. The mortar supply tank 2 begins to move, ensuring that the laser beam shone downwards from the laser instrument 5 is aligned with the joint 101 during the movement.

[0057] Then, the air pump 6 and the air pressure regulating device 7 are started simultaneously. The air pump 6 independently supplies air to the first air inlet pipe 4035a and the second air inlet pipe 4035b through the built-in multi-way valve. The air outlet 4036 of the first air inlet pipe 4035a and the second air inlet pipe 4035b blows air along the air guide surface 4039 to blow air onto the mortar in the horizontal gap 8. The mortar overflowing from the horizontal gap 8 moves towards the joint, thus reducing the overflow of mortar and ensuring that the mortar can fully fill the joint 101 area.

[0058] In addition, combined Figure 1 , Figure 6 During the movement of mortar supply tank 2:

[0059] Scenario 1: When the first distance sensor 4037a detects a decrease in distance due to mortar overflow, the air pump 6 increases the airflow rate to the first air intake pipe 4035a until the distance information detected by the first distance sensor 4037a returns to normal, then the air pump 6 reduces the airflow rate to the first air intake pipe 4035a to the normal rate.

[0060] Scenario 2: When the second distance sensor 4037b detects a decrease in distance due to mortar overflow, the air pump 6 increases the airflow rate to the second air intake pipe 4035b until the distance information detected by the second distance sensor 4037b returns to normal, at which point the air pump 6 reduces the airflow rate to the second air intake pipe 4035b to the normal rate.

[0061] Scenario 3: When the first distance sensor 4037a or the second distance sensor 4037b detects a decrease in distance due to mortar overflow, the air pressure regulating device 7 reduces the air pressure in the upper air chamber 4031a to P. c -ΔP m Pc is the air pressure reference value when the mortar on both sides of the horizontal gap 8 has not overflowed, ΔP m A reference unit value for reducing the air pressure in the upper air chamber 4031a.

[0062] Scenario 4: When the first distance sensor 4037a and the second distance sensor 4037b simultaneously detect a decrease in distance due to mortar overflow, the air pressure regulating device 7 reduces the air pressure in the upper air chamber 4031a to P. c -2ΔP m .

[0063] Finally, when the mortar supply tank 2 moves 20-30cm before the end of the joint, close the valve of the mortar supply tank 2 to inject mortar into the guide pipe 3. The mortar supply tank 2 continues to move at a constant speed toward the end of the joint 101. The air pump 6 continues to supply air to the first air inlet pipe 4035a and the second air inlet pipe 4035b. At the same time, the air pressure regulating device 7 gradually increases the air pressure of the upper air chamber 4031a, gradually discharging the remaining mortar in the mortar chamber 4031b and injecting it into the remaining section of the joint 101 area. Then, the air pump 6 and the air pressure regulating device 7 are turned off.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
