Description

Technical Field

[0001] The invention belongs to the field of construction, in particular to a connecting device for building sand-soil bricks and a building brick curtain wall. Background Art

[0002] In the construction industry, brick curtain wall refers to the non-load-bearing exterior wall structure of a building, usually composed of bricks and a supporting structure behind it. The curtain wall not only has a decorative effect, but also can provide a certain degree of thermal insulation, heat insulation and sound insulation. However, the traditional brick curtain wall construction method has many inconveniences.

[0003] Existing brick curtain walls are usually installed in an orderly stacking manner, fixed from bottom to top, which is not only cumbersome but also inefficient. Construction workers need to spend a lot of time and energy to ensure the accurate alignment and fixation of each brick, which greatly increases the construction period and cost.

[0004] In view of the shortcomings of the existing technology, there is an urgent need for a modular sand-soil brick connection structure that can effectively simplify the installation process, reduce construction difficulty, and improve work efficiency. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a connection device for building sand bricks and a building brick curtain wall, which can overcome the shortcomings of traditional installation methods and improve the efficiency of curtain wall construction.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows: A connecting device for building sand bricks comprises a sand brick and a base, wherein the sand brick is provided with a plurality of through grooves; the base is provided with a plurality of slots, each of which is slidably fitted with a clamping block, each of which is provided with a limiting structure for limiting the moving distance of the clamping block; the sand brick is provided with a plurality of through grooves, and when the clamping block is aligned with the through grooves respectively, the clamping block slides into the through grooves and is clamped with the sand brick.

[0007] The above scheme has the following beneficial effects: 1. In this scheme, a row of sand bricks is used as a stacking unit. The sand bricks of a stacking unit are placed on the base respectively, and each sand brick is clamped with a clamping block. The base and a row of sand bricks are used as a separate module, and each module is stacked layer by layer from bottom to top. During the stacking process, the base of the previous layer is pushed and pulled in the horizontal direction until the clamping block on the base of the previous layer is aligned with the through groove on the sand brick of the next layer. The clamping block of the base of the previous layer will slide along the slot into the through groove on the sand brick of the next layer at the same time, and the clamping block will be limited between the sand brick of the next layer and the base of the previous layer by the limiting mechanism, so that each module can be installed layer by layer.

[0008] Compared with the traditional installation method, the present invention simplifies the installation process of the curtain wall into the stacking of multiple modules through modular design, which greatly reduces the construction time and labor costs.

[0009] 2. This solution uses the sliding fit between the card block and the through slot, so construction workers can quickly and accurately connect the modules without the need for tedious fixing operations, which significantly improves construction efficiency.

[0010] 3. In this solution, the engagement structure between the block and the through slot and the setting of the limiting structure ensure the stability and safety of the curtain wall structure and reduce the risks during the construction process.

[0011] Furthermore, a plurality of cleaning mechanisms are provided on the base; the cleaning mechanisms include at least one group of first slide grooves; a nozzle and a telescopic tube are slidably fitted in the first slide grooves, the air inlet end of the nozzle is connected to the telescopic tube, and the other end of the telescopic tube is connected to an air flow channel; the air flow channel is used to transport gas to each telescopic tube respectively, and the air flow channel is connected to a wind capture system, which is used to capture external airflow.

[0012] Beneficial effects: During the use of curtain walls, dust, dirt and other impurities will inevitably accumulate. The cleaning mechanism can effectively remove dust, debris and other impurities on the surface and joints of sand bricks. The wind capture system can capture the natural airflow from the outside and provide power for the cleaning mechanism without additional energy consumption. This not only reduces construction costs, but also conforms to the energy-saving and environmental protection concept of modern buildings.

[0013] Furthermore, the limiting mechanism includes a limiting groove, a second sliding groove and a limiting block; the limiting groove is arranged on the side wall of the locking block, the second sliding groove is arranged on the side wall of the slot, the limiting block and the second sliding groove are slidably matched, and a spring is arranged between the limiting block and the inner wall of the second sliding groove. When the limiting groove is aligned with the second sliding groove, the limiting block is engaged with the limiting groove.

[0014] Beneficial effects: The setting of the limit mechanism enables the block to be firmly locked in the slot after sliding to the predetermined position, avoiding the block from loosening or falling off due to external force or vibration. This greatly enhances the stability and safety of the curtain wall structure. The engagement of the limit slot and the limit block ensures that the block can be accurately aligned and fixed in the predetermined position, thereby improving the installation accuracy and overall quality of the curtain wall.

[0015] Furthermore, a magnetic adsorption component is also arranged in the first slide groove; the magnetic adsorption component includes a permanent magnet and a magnetic force generating component for cooperating with the permanent magnet to generate suction force, the permanent magnet is located on the nozzle, and the magnetic force generating component is located on the side of the first slide groove away from the permanent magnet.

[0016] Beneficial effect: When the air pressure in the telescopic tube rises to a level sufficient to overcome the suction between the magnetic adsorption components, the nozzle will automatically extend out of the first chute to clean the surface of the sand brick. This design enables the cleaning mechanism to intelligently adjust the working state of the nozzle according to the change in air pressure without manual intervention, thereby improving cleaning efficiency and automation. When the nozzle stops working, the magnetic adsorption component can store the nozzle in the first chute, avoiding exposure and damage to the nozzle in the external environment, while not destroying the overall aesthetics of the curtain wall.

[0017] Furthermore, the wind-catching system includes a wind-catching carrier; a plurality of wind-catching slots are arranged on the wind-catching carrier, each of which is connected to the airflow channel respectively, and a boosting mechanism for increasing the air pressure in the airflow channel is arranged between the wind-catching slots and the airflow channel.

[0018] Beneficial effect: The air catching slot enables the cleaning mechanism to efficiently capture and utilize external airflow, thereby improving cleaning efficiency.

[0019] The setting of the booster mechanism increases the pressure of the airflow entering the airflow channel, so that the nozzle can spray the airflow more strongly, thereby more effectively removing impurities such as dust and debris on the surface and connection parts of the sand brick.

[0020] The design of the wind catching slot and the pressurizing mechanism enables the cleaning mechanism to adapt to different environments and climatic conditions. Whether in areas with strong winds or areas with weak winds, the cleaning mechanism can obtain sufficient airflow supply and maintain a stable cleaning effect.

[0021] Furthermore, the boost mechanism includes a functional cavity; a rotating shaft is arranged in the functional cavity, and both ends of the rotating shaft are rotatably connected to the inner wall of the functional cavity respectively; a plurality of discs are arranged on the rotating shaft, and adjacent discs and the discs and the inner wall of the functional cavity are separated by a preset distance, and the preset distance is not greater than 2 times the boundary layer thickness of the air; exhaust ports are arranged on the side of the disc close to the rotating shaft; a plurality of air inlet pipes are arranged in the tangential direction of the functional cavity, and the air inlet pipes are respectively connected to the wind catching grooves; the functional cavity is connected to an air outlet pipe along the axial direction of the rotating shaft, and the air outlet pipe is connected to the air flow channel.

[0022] Beneficial effects: The disc and the shaft design form a turbine-like structure. When the external airflow enters the air inlet pipe through the wind-catching slot, the airflow hits the disc and drives the shaft to rotate. Due to the preset distance between the discs and the interval between the discs and the inner wall of the functional cavity, the rotating disc can effectively accelerate and compress the airflow, thereby increasing the pressure of the airflow entering the airflow channel. This design enables the jet head to spray a stronger airflow, enhancing the cleaning effect.

[0023] The supercharging mechanism uses the natural airflow captured by the wind catching slot as a power source, and can achieve the supercharging function without additional energy consumption. This self-driving feature not only reduces operating costs, but also conforms to the concept of energy conservation and environmental protection.

[0024] The boundary layer of air is a thin layer of airflow formed when the airflow contacts a solid surface. When the preset distance is no more than 2 times the thickness of the boundary layer of air, the airflow between the disc and the inner wall of the functional cavity flows more smoothly, reducing the formation of eddies and turbulence. This optimized airflow helps to improve the efficiency of the supercharging mechanism, so that more energy is used to compress the airflow instead of being consumed in eddies and turbulence. Because the airflow flows more smoothly, the disc can accelerate and compress the airflow more effectively. This increases the pressure of the airflow entering the airflow channel, allowing the jet head to spray a stronger airflow, thereby improving the cleaning effect.

[0025] Furthermore, it also includes a backup power system, a collection unit and a control unit; the backup power system is used to drive the rotating shaft to rotate; the collection unit is used to collect environmental parameters; the control unit is used to determine whether it is necessary to control the operation of the backup power system based on the environmental parameters.

[0026] Beneficial effect: The setting of the backup power system ensures that the booster mechanism can still work normally when there is insufficient natural wind or no wind. This improves the reliability and stability of the entire cleaning mechanism and ensures that the cleaning work of the curtain wall will not be interrupted due to changes in external conditions.

[0027] The collection unit is used to collect environmental parameters in real time, such as wind speed and wind direction. The control unit intelligently determines whether to start the backup power system based on these environmental parameters. This intelligent control mechanism enables the cleaning mechanism to automatically adjust the working mode according to changes in the external environment, improving the flexibility and adaptability of the system.

[0028] Furthermore, the magnetic force generating element is a first electromagnet, and the first electromagnet is electrically connected to the control unit.

[0029] Beneficial effect: The electrical connection between the first electromagnet and the control unit enables the magnetic adsorption to be intelligently controlled. The control unit can flexibly adjust the power-on state of the first electromagnet according to environmental parameters, thereby changing the adsorption or release state of the jet head (corresponding to the non-jet and jet modes). This intelligent control mechanism improves the automation and flexibility of the cleaning mechanism.

[0030] Furthermore, an adjustment mechanism is also provided in the functional cavity; the adjustment mechanism includes a plurality of third slide grooves, the third slide grooves are located on the outside of the rotating shaft, the third slide grooves correspond to the discs one by one, and the discs close to one end of the rotating shaft are slidably matched with the third slide grooves, and the discs are made of magnetic material, and the magnetism of adjacent discs is the same; a sliding sealing groove is also connected on the inner wall of the functional cavity, and a magnetic block is slidably matched in the sliding sealing groove, and the magnetic block has the same magnetism as the adjacent disc, and a second electromagnet is provided on one side of the magnetic block, and the second electromagnet is electrically connected to the control unit.

[0031] Beneficial effect: By controlling the power-on state and current size of the second electromagnet, the magnetic interaction between the magnetic block and the disc can be changed, thereby adjusting the position of the disc in the third chute, and then dynamically changing the spacing between adjacent discs. This design enables the boosting mechanism to flexibly adjust the boosting effect according to actual needs to meet different cleaning needs.

[0032] A building brick curtain wall is composed of a connecting device for building sand-soil bricks and sand-soil bricks.

[0033] Beneficial effect: The connection device makes the installation of sand bricks more convenient, without complicated on-site processing or adjustment. This greatly simplifies the construction process, shortens the construction period, and reduces construction costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installed", "connected" and "connected" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the internal connection between two components. It can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances.

[0050] The following is further described in detail through specific implementation methods: Embodiment 1 is basically as attached Figure 1-Figure 12 As shown: a connecting device for building sand bricks, including a sand brick 1 and a base 2. In this embodiment, the base 2 is in the shape of a long plate; a plurality of slots 213 are opened on the base 2 along the length direction, and a block 201 is slidably fitted in each of the slots 213. Preferably, the block 201 is a rectangular block. In some other embodiments, the block 201 is in the shape of a cylinder, and a limiting structure for limiting the moving distance of the block 201 is provided on the block 201.

[0051] Specifically, the limiting mechanism includes a limiting groove 204, a second sliding groove 210 and a limiting block 212; Figure 6 and attached Figure 8 As shown, the limit groove 204 is provided on the left and right side walls of the block 201. Preferably, the cross-sectional shape of the limit groove 204 is an inverted right triangle. The second slide groove 210 is provided on the left and right side walls of the slot 213. The limit block 212 is slidably matched with the second slide groove 210. A spring 211 is provided between the limit block 212 and the inner wall of the second slide groove 210. The two ends of the spring 211 are respectively welded and fixed to the limit block 212 and the inner wall of the second slide groove 210. When the limit When the groove 204 is aligned with the second slide groove 210, the limit block 212 is engaged with the limit groove 204. Preferably, the head of the limit block 212 is a shape that matches the limit groove 204. In this embodiment, the synergistic effect of the limit block 212 and the limit groove 204 only supports the block 201 to move a certain distance from top to bottom (the specific distance depends on the actual situation). When the curtain wall needs to be disassembled, the block 201 only needs to be lifted up, and the block 201 can be free from the restriction of the limit block 212.

[0052] Preferably, two groups of through grooves 101 are provided on the sand brick 1 (the number of the through grooves 101 depends on the specific situation). When the clamping blocks 201 are aligned with the through grooves 101 , the clamping blocks 201 slide into the through grooves 101 and engage with the sand brick 1 .

[0053] The specific implementation process is as follows: first, fix the base 2 in a suitable position, insert the card blocks 201 into the slots 213 respectively (the posture after assembly is as shown in the attached figure). Figure 6Then align the slots 101 of the sand brick 1 with the blocks 201 on the base 2 and insert them to complete the assembly of one module. Repeat the above process to complete the modular assembly of all the sand bricks 1 and the base 2, and then stack the modules alternately (as shown in the figure). Figure 1 As shown in the figure, align the block 201 of the upper layer (upper module) with the through groove 101 of the sand brick 1 on the lower layer base 2. At this time, the block 201 of the upper layer slides into the through groove 101 of the sand brick 1 of the lower layer under the action of its own gravity until the limit groove 204 on the block 201 moves down to engage with the limit block 212. Repeat this process until all modules are assembled and the batch installation of sand bricks 1 is completed.

[0054] When disassembly is required, the base 2 of each module is lifted upward and removed from top to bottom, and the batch disassembly of each sand brick 1 can be completed.

[0055] The only difference between the second embodiment and the first embodiment is that a plurality of cleaning mechanisms 203 are further provided on the base 2 .

[0056] Specifically, the cleaning mechanism 203 includes at least one group of first slide grooves 207, the cross section of the first slide grooves 207 is "﹄" shaped, and in this embodiment, two groups of first slide grooves 207 are provided, which are mirror-symmetrically provided on the left side of the base 2; preferably, in combination with the attached Figure 6 and attached Figure 7 As shown, the first slide groove 207 is slidably matched with the nozzle 209 and the telescopic tube 205. Preferably, a plurality of "L"-shaped channels are arranged side by side in the nozzle 209, and the right end (i.e., the air inlet end) of the "L"-shaped channel is connected to the telescopic tube 205. In this embodiment, the telescopic tube 205 adopts a bellows structure, and the right end of the telescopic tube 205 is connected to the airflow channel 202; the airflow channel 202 is used to transport gas to each telescopic tube 205 respectively, and the airflow channel 202 is connected to a wind capture system, which is used to capture external airflow.

[0057] Specifically, the wind capture system includes a wind capture carrier 3. In the present embodiment, the wind capture carrier 3 is a rectangular structure as a whole. The wind capture carrier 3 is connected to the base 2 by mortise and tenon, that is, the side of the wind capture carrier 3 is provided with a mortise, and one end of the base 2 is inserted into the mortise and tenoned with the wind capture carrier 3; a plurality of wind capture grooves 301 are provided on the wind capture carrier 3, preferably, the wind capture grooves 301 are conical structures, and the wind capture grooves 301 are respectively connected to the airflow channel 202, and a boosting mechanism is provided between the wind capture grooves 301 and the airflow channel 202.

[0058] Specifically, the booster mechanism includes a functional chamber 304. In this example, the functional chamber 304 is cylindrical. Fig. 9 and attached Fig.10As shown, the functional cavity 304 is opened inside the wind-catching carrier 3, and a rotating shaft 309 is arranged in the functional cavity 304. The two ends of the rotating shaft 309 are respectively rotatably connected to the inner wall of the functional cavity 304. A plurality of disks 305 are arranged on the rotating shaft 309 (the number of the disks 305 is determined according to the actual pressure increase requirement). There is a preset distance between adjacent disks 305 and between the disks 305 and the inner wall of the functional cavity 304, and the preset distance is not greater than 2 times the boundary layer thickness of the air; the disks 305 are each provided with an exhaust port 305 on one side close to the rotating shaft 309. 10. The exhaust port 310 is arranged along the length direction of the rotating shaft 309. A plurality of air inlet pipes 307 are connected in the tangential direction of the functional cavity 304 (i.e., the tangential direction of the disk 305). Each air inlet pipe 307 corresponds to an air catching slot 301. The other ends of the air inlet pipes 307 are respectively connected to the air catching slots 301. The functional cavity 304 is connected to an air outlet pipe 308 in the axial direction of the rotating shaft 309. The air outlet pipe 308 is connected to the air flow channel 202. Specifically, the air outlet pipe 308 is connected to the functional cavity 304 via a connecting pipe 311.

[0059] Preferably, a magnetic adsorption component is further provided in the first slide groove 207; the magnetic adsorption component includes a permanent magnet 208 and a magnetic force generating member for cooperating with the permanent magnet 208 to generate an adsorption force. Figure 7 As shown, the permanent magnet 208 is welded and fixed to the right side of the nozzle 209, and the magnetic force generating element is embedded in the first slide groove 207 on the side away from the permanent magnet 208. In this embodiment, the magnetic force generating element is not limited to components made of magnetic materials such as iron sheets.

[0060] Specific implementation process: When the wind blows, the airflow is introduced into the functional cavity 304 through the wind-catching slots 301 arranged in all directions of the wind-catching carrier 3. After the airflow enters the functional cavity 304, since the air is a fluid (having a boundary layer effect, that is, when the fluid (gas or liquid) is affected by the viscosity, a very thin boundary layer will be formed on the edge of the pipe wall or other objects. In this boundary layer, the flow velocity close to the fixed surface is almost zero, and the farther away from the surface, the greater the velocity), the air will drive the disc 305 to rotate during the flow process. At this time, the flow trajectory of the air in the functional cavity 304 is spiral, and it continues to approach the exhaust port 310, and finally passes through the exhaust port 310 and enters the connecting pipe 311-air outlet pipe 308-air flow channel 202-telescopic pipe 205-injection head 209 in sequence, until the air pressure in the telescopic pipe 205 increases to be greater than the suction force generated by the magnetic adsorption component, the injection head 209 will pop out of the first slide groove 207 and clean the surface of the curtain wall, thereby reducing the adhesion of impurities such as dust.

[0061] The only difference between Example 3 and Example 2 is that it also includes a backup power system, a collection unit and a control unit; the backup power system is used to drive the rotating shaft 309 to rotate. Preferably, the backup power system in this embodiment is composed of a servo motor 303, a coupling and other components. The collection unit is used to collect environmental parameters. Preferably, the collection unit in this embodiment includes a wind speed sensor and a wind direction sensor, and the environmental parameters are data such as wind speed and wind direction. The control unit is used to determine whether it is necessary to control the operation of the backup power system based on the environmental parameters.

[0062] Preferably, the functional cavity 304 is also provided with an adjustment mechanism; Fig.12 As shown, the adjustment mechanism includes a plurality of third slide grooves 312, the third slide grooves 312 are arranged outside the rotating shaft 309, the third slide grooves 312 correspond to the discs 305 one by one, and the discs 305 close to the rotating shaft 309 are slidably matched with the third slide grooves 312, the discs 305 are made of magnetic material, and the magnetism of adjacent discs 305 is the same; Fig.10 As shown, the inner wall of the functional cavity 304 is also connected to a sliding sealing groove, in which a magnetic block 306 is slidably fitted. The magnetic block 306 has the same magnetic properties as the adjacent disk 305. A second electromagnet 302 is embedded on the left side of the magnetic block 306, and the second electromagnet 302 is electrically connected to the control unit.

[0063] Preferably, in this embodiment, the magnetic force generating element is a first electromagnet 206, and the first electromagnet 206 is electrically connected to the control unit.

[0064] Specific implementation process: When the wind speed collected by the collection unit is lower than the threshold, or the wind direction does not match the position of the wind catching slot 301 (i.e., the wind catching slot 301 captures less airflow), the control unit will control the servo motor 303 to operate or adjust the spacing of the disc 305, and use the servo motor 303 to take over the work of natural wind. The operation of the servo motor 303 will drive the rotating shaft 309 to rotate, and then drive the disc 305 to rotate to suck the outside air into the wind catching slot 301, thereby ensuring the clean and normal operation of the curtain wall when there is no wind or the wind is small.

[0065] At the same time, the control unit also controls the first electromagnet 206 to operate, so that the first electromagnet 206 generates a repulsive force to push the nozzle 209 and the permanent magnet 208 out of the first slide groove 207, so as to avoid the low air pressure in the telescopic tube 205, which causes the nozzle 209 to fail to work normally.

[0066] When the external natural wind force is relatively small, the control unit controls the operation of the second electromagnet 302, and the repulsive force generated by the second electromagnet 302 pushes the magnetic block 306 away from the sliding sealing groove, thereby reducing the distance between each disk 305 within a certain range, reducing the leakage of air between the disks 305, and improving the interaction between the air and the disk 305, thereby improving the boosting effect of the boosting mechanism.

[0067] The only difference between the fourth embodiment and the third embodiment is that a building brick curtain wall is provided, which is composed of the connecting device of the building sand brick and the sand brick 1. Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, the connecting device for building sand bricks is mainly used to connect sand bricks 1 to form curtain walls. In this embodiment, the sand brick 1 is a building material, which is mainly made of raw materials such as sand and soil through processing. The present invention does not limit the material of the sand brick 1. In this embodiment, a guide groove 102 is also opened on the surface of the sand brick 1 to facilitate the air flow channel 202 output by the nozzle 209 to improve the cleaning effect.

[0068] The above is only an embodiment of the present invention, and the common knowledge such as the known specific structure and / or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the present invention, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
