Description

Technical Field

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

[0002] In the construction industry, a brick curtain wall refers to a building's non-load-bearing exterior enclosure, typically composed of bricks and a supporting structure. Curtain walls not only serve a decorative purpose but also provide a degree of thermal insulation, heat isolation, and soundproofing. However, traditional brick curtain wall construction methods present numerous inconveniences.

[0003] Existing brick curtain walls are typically installed in an orderly stacked manner, fixed from bottom to top. This installation method is not only cumbersome but also inefficient. Construction workers need to spend a lot of time and energy to ensure that each brick is accurately aligned and fixed, 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:

[0007] A connecting device for building sand bricks includes a sand brick and a base. 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, and each of the clamping blocks 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, the clamping block slides into the through grooves and engages with the sand brick.

[0008] The above scheme has the following beneficial effects:

[0009] 1. This solution uses a row of sand bricks as a stacking unit. The sand bricks of a stacking unit are placed on the base respectively, and each sand brick is locked with a clamping block. The base and a row of sand bricks are used as a separate module. The modules are stacked layer by layer from bottom to top. During the stacking process, the base of the upper layer is pushed and pulled horizontally until the clamping block on the base of the upper layer is aligned with the through groove on the sand brick of the lower layer. The clamping block of the base of the upper layer will simultaneously slide along the slot into the through groove on the sand brick of the lower layer, and the clamping block will be restricted between the sand brick of the lower layer and the base of the upper layer by a limiting mechanism, so that each module can be installed layer by layer.

[0010] Compared with traditional installation methods, the present invention simplifies the installation process of curtain walls into stacking multiple modules through modular design, greatly reducing construction time and labor costs.

[0011] 2. This solution utilizes the sliding fit between the clamping blocks and the through slots, allowing construction workers to quickly and accurately connect the modules without the need for tedious fixing operations, significantly improving construction efficiency.

[0012] 3. In this solution, the locking 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.

[0013] Furthermore, several cleaning mechanisms are also provided on the base; the cleaning mechanisms include at least one group of first slide grooves; a nozzle head and a telescopic tube are slidably fitted in the first slide groove, the air inlet end of the nozzle head 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.

[0014] Benefits: During the use of curtain walls, dust, dirt, and other impurities inevitably accumulate. The cleaning mechanism effectively removes dust, debris, and other impurities from the surfaces and joints of sand-soil bricks. The air capture system captures natural airflow, powering the cleaning mechanism without requiring additional energy. This not only reduces construction costs but also conforms to the energy-saving and environmentally friendly principles of modern architecture.

[0015] Furthermore, the limiting mechanism includes a limiting groove, a second slide groove and a limiting block; the limiting groove is arranged on the side wall of the blocking block, the second slide groove is arranged on the side wall of the slot, the limiting block slides in cooperation with the second slide groove, and a spring is arranged between the limiting block and the inner wall of the second slide groove. When the limiting groove is aligned with the second slide groove, the limiting block engages with the limiting groove.

[0016] Beneficial Effects: The positioning mechanism securely locks the block into place after it has slid to its intended position, preventing it from loosening or falling out due to external forces or vibration. This significantly enhances the stability and safety of the curtain wall structure. The engagement between the positioning slot and the positioning block ensures the block is accurately aligned and secured in its intended position, improving the installation precision and overall quality of the curtain wall.

[0017] Furthermore, a magnetic adsorption component is also provided in the first slide; 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 head, and the magnetic force generating component is located on the side of the first slide away from the permanent magnet.

[0018] Beneficial Effect: When the air pressure within the telescopic tube rises high enough to overcome the suction between the magnetic components, the nozzle automatically extends from the first chute to clean the surface of the sand and soil bricks. This design allows the cleaning mechanism to intelligently adjust the nozzle's operating state based on air pressure changes, eliminating the need for manual intervention and improving cleaning efficiency and automation. When the nozzle is temporarily suspended, the magnetic component retracts it into the first chute, preventing it from being exposed to the outside world and potentially damaging it, while also preserving the overall aesthetics of the curtain wall.

[0019] Furthermore, the wind-catching system includes a wind-catching carrier; a plurality of wind-catching slots are provided on the wind-catching carrier, each of which is connected to the air flow channel respectively; a boosting mechanism for increasing the air pressure in the air flow channel is provided between the wind-catching slots and the air flow channel.

[0020] Beneficial effect: The air-catching slot enables the cleaning mechanism to efficiently capture and utilize external airflow, thereby improving cleaning efficiency.

[0021] The setting of the boost 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 dust, debris and other impurities on the surface and connection parts of the sand bricks.

[0022] 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 in areas with weak winds, the cleaning mechanism can obtain sufficient air supply and maintain a stable cleaning effect.

[0023] Furthermore, the boosting mechanism includes a functional cavity; a rotating shaft is provided 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 provided 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 provided on the side of the disc close to the rotating shaft; a plurality of air inlet pipes are provided in the tangential direction of the functional cavity, and the air inlet pipes are respectively connected to the wind catching slots; 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.

[0024] Benefits: The discs and shaft form a turbine-like structure. When air flows through the air-catching slots and into the air inlet duct, it strikes the discs, driving the shaft to rotate. Due to the predetermined distance between the discs and the spacing between them and the inner wall of the functional cavity, the rotating discs effectively accelerate and compress the airflow, increasing the pressure of the air entering the airflow channel. This design enables the nozzle to deliver a more powerful airflow, enhancing cleaning effectiveness.

[0025] The supercharging mechanism utilizes the natural airflow captured by the air chute as its power source, achieving supercharging without the need for additional energy consumption. This self-driven feature not only reduces operating costs but also conforms to the concept of energy conservation and environmental protection.

[0026] The air boundary layer is a thin layer of air formed when airflow contacts a solid surface. When the preset distance is no greater than twice the thickness of the air boundary layer, the airflow between the disc and the inner wall of the functional cavity is smoother, reducing the formation of vortices and turbulence. This optimized airflow helps improve the efficiency of the supercharging mechanism, allowing more energy to be used to compress the airflow rather than consumed in vortices and turbulence. Because the airflow is smoother, the disc is able to accelerate and compress the airflow more effectively. This increases the pressure of the airflow entering the airflow channel, allowing the nozzle to spray a more powerful airflow, thereby improving the cleaning effect.

[0027] Furthermore, it also includes a backup power system, a collection unit and a control unit; the backup power system is used to drive the rotation of the shaft; the collection unit is used to collect environmental parameters; and 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.

[0028] Beneficial effect: The backup power system ensures that the booster mechanism can still operate normally when there is insufficient or no natural wind. This improves the reliability and stability of the entire cleaning mechanism and ensures that the curtain wall cleaning work will not be interrupted by changes in external conditions.

[0029] The data collection unit collects real-time environmental parameters, such as wind speed and direction. Based on these parameters, the control unit intelligently determines whether to activate the backup power system. This intelligent control mechanism enables the cleaning mechanism to automatically adjust its operating mode based on changes in the external environment, improving the system's flexibility and adaptability.

[0030] Furthermore, the magnetic force generating element is a first electromagnet, and the first electromagnet is electrically connected to the control unit.

[0031] Beneficial Effect: The electrical connection between the first electromagnet and the control unit enables intelligent control of the magnetic attraction. The control unit can flexibly adjust the power supply state of the first electromagnet based on environmental parameters, thereby changing the attraction or release state of the air jet head (corresponding to non-air jet and air jet modes). This intelligent control mechanism enhances the automation and flexibility of the cleaning mechanism.

[0032] 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 one-to-one to the discs, and the discs close to one end of the rotating shaft are slidably engaged 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 engaged in the sliding sealing groove, and the magnetic block has the same magnetism as the adjacent disc. A second electromagnet is provided on one side of the magnetic block, and the second electromagnet is electrically connected to the control unit.

[0033] Beneficial Effect: By controlling the power supply state and current level of the second electromagnet, the magnetic interaction between the magnet and the disc can be altered, thereby adjusting the position of the disc within the third chute and, in turn, dynamically changing the spacing between adjacent discs. This design allows the boost mechanism to flexibly adjust the boost effect according to actual needs, meeting different cleaning requirements.

[0034] A building brick curtain wall is composed of a connecting device for building sand-soil bricks and sand-soil bricks.

[0035] Beneficial Effects: The connection device makes the installation of sand-soil bricks more convenient, without the need for 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] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0051] 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 communication 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.

[0052] The following is further described in detail through specific implementation methods:

[0053] Example 1 is basically as shown in the attached Figures 1-12 As shown: A connection 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 card block 201 is slidably fitted in each of the slots 213. Preferably, the card block 201 is a rectangular block. In some other embodiments, the card block 201 is in the shape of a cylinder, and a limiting structure for limiting the moving distance of the card block 201 is provided on the card block 201.

[0054] 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 limiting groove 204 is provided on the left and right side walls of the card block 201. Preferably, the cross-sectional shape of the limiting 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 limiting block 212 slides with the second slide groove 210. A spring 211 is provided between the limiting block 212 and the inner wall of the second slide groove 210. The two ends of the spring 211 are respectively welded to the limiting block 212 and the inner wall of the second slide groove 210. When the limiting block 212 is in the state of being pressed, the limiting block 212 and the inner wall of the second slide groove 210 are respectively welded to the limiting block 212 and the inner wall of the second slide groove 210. 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 dismantled, the block 201 only needs to be lifted upward, and the block 201 can be free from the restriction of the limit block 212.

[0055] Preferably, two groups of through slots 101 are provided on the sand brick 1 (the number of through slots 101 depends on the specific situation). When the clamping blocks 201 are aligned with the through slots 101 , the clamping blocks 201 slide into the through slots 101 and engage with the sand brick 1 .

[0056] 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 6As shown), then 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 a 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 in an interlaced manner (as shown in the attached 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 limiting groove 204 on the block 201 moves down to engage with the limiting block 212. Repeat this process until all modules are assembled and the batch installation of sand bricks 1 is completed.

[0057] 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.

[0058] The only difference between Example 2 and Example 1 is that a plurality of cleaning mechanisms 203 are further provided on the base 2 .

[0059] Specifically, the cleaning mechanism 203 includes at least one set of first chutes 207. The cross section of the first chutes 207 is in the shape of "﹄". In this embodiment, there are two sets of first chutes 207, which are mirror-symmetrically opened 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 fitted with a nozzle 209 and a telescopic tube 205. Preferably, a plurality of "L"-shaped channels are provided side by side in the nozzle head 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 air flow channel 202; the air flow channel 202 is used to transport gas to each telescopic tube 205 respectively, and the air flow channel 202 is connected to a wind capture system, which is used to capture external airflow.

[0060] Specifically, the wind-catching system includes a wind-catching carrier 3. In this embodiment, the wind-catching carrier 3 is a rectangular structure as a whole. The wind-catching carrier 3 is connected to the base 2 by mortise and tenon, that is, the side of the wind-catching carrier 3 is provided with a mortise, and one end of the base 2 is inserted into the mortise and tenoned with the wind-catching carrier 3; a plurality of wind-catching slots 301 are provided on the wind-catching carrier 3. Preferably, the wind-catching slots 301 are conical structures, and the wind-catching slots 301 are respectively connected to the airflow channel 202, and a boosting mechanism is provided between the wind-catching slots 301 and the airflow channel 202.

[0061] Specifically, the pressurizing mechanism includes a functional chamber 304. In this embodiment, the functional chamber 304 is cylindrical. Figure 9 and attached Figure 10As shown, the functional cavity 304 is opened inside the wind-catching carrier 3, and a rotating shaft 309 is provided in the functional cavity 304. The two ends of the rotating shaft 309 are respectively connected to the inner wall of the functional cavity 304 for rotation. A plurality of disks 305 are provided on the rotating shaft 309 (the number of 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. The preset distance is not greater than 2 times the boundary layer thickness of the air; an exhaust port 305 is provided on each side of the disk 305 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 to the functional cavity 304 in the tangential direction (i.e., the tangential direction of the disk 305), each air inlet pipe 307 corresponds to an air catching slot 301, and 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 the air outlet pipe 308 along the axial direction of the rotating shaft 309, and the air outlet pipe 308 is connected to the air flow channel 202. Specifically, the air outlet pipe 308 and the functional cavity 304 are connected via a connecting pipe 311.

[0062] Preferably, a magnetic adsorption component is further provided in the first chute 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 attractive force. Figure 7 As shown, the permanent magnet 208 is welded and fixed to the right side of the nozzle 209, and the magnetic generating element is embedded in the first slide groove 207 on the side away from the permanent magnet 208. In this embodiment, the magnetic generating element is not limited to components made of magnetic materials such as iron sheets.

[0063] Specific implementation process: When wind blows, airflow is introduced into the functional cavity 304 through the air-catching slots 301 arranged in all directions of the air-catching carrier 3. Once the airflow enters the functional cavity 304, because air is a fluid (exhibiting a boundary layer effect, i.e., when a fluid (gas or liquid) is affected by viscosity, a very thin boundary layer forms at the edge of the pipe wall or other objects. Within this boundary layer, the flow velocity near the fixed surface is almost zero, while the velocity increases the further away from the surface). During the flow, the air drives the disc 305 to rotate. At this time, the air flow trajectory within the functional cavity 304 is spiral, and it continuously approaches the exhaust port 310. Finally, it passes through the exhaust port 310 and enters the connecting pipe 311, the air outlet pipe 308, the air flow channel 202, the telescopic pipe 205, and the nozzle 209 in sequence. When the air pressure in the telescopic pipe 205 rises to a level greater than the suction force generated by the magnetic adsorption component, the nozzle 209 will pop out of the first chute 207 and clean the surface of the curtain wall, thereby reducing the adhesion of dust and other impurities.

[0064] The only difference between Example 3 and Example 2 is that it also includes a backup power system, a data acquisition unit, and a control unit. The backup power system is used to drive the rotation of the rotating shaft 309. Preferably, in this embodiment, the backup power system is composed of a servo motor 303, a coupling, and other components. The data acquisition unit is used to collect environmental parameters. Preferably, in this embodiment, the data acquisition unit includes a wind speed sensor and a wind direction sensor. The environmental parameters include wind speed, wind direction, and other data. The control unit is used to determine whether to control the operation of the backup power system based on the environmental parameters.

[0065] Preferably, an adjustment mechanism is also provided in the functional cavity 304; Figure 12 As shown, the adjustment mechanism includes a plurality of third chutes 312, which are opened on the outside of the rotating shaft 309. The third chutes 312 correspond to the discs 305 one by one. The discs 305 close to the rotating shaft 309 are all slidably matched with the third chutes 312. The discs 305 are made of magnetic material, and the magnetism of adjacent discs 305 is the same. Figure 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.

[0066] 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.

[0067] 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 (that is, 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, using the servo motor 303 to take over the work of natural wind power. The operation of the servo motor 303 will drive the rotation shaft 309, and then drive the disc 305 to rotate and 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 weak.

[0068] 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, pushing the nozzle 209 and the permanent magnet 208 out of the first slide 207, thereby preventing the air pressure in the telescopic tube 205 from being too low, which may cause the nozzle 209 to malfunction.

[0069] 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.

[0070] The only difference between Example 4 and Example 3 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 primarily used to connect sand bricks 1 to form curtain walls. In this embodiment, sand brick 1 is a building material primarily made from raw materials such as sand and soil. The present invention does not limit the material of sand brick 1. In this embodiment, the surface of sand brick 1 is also provided with a guide groove 102 to facilitate the air flow channel 202 output by the nozzle 209, thereby improving the cleaning effect.

[0071] The above is only an embodiment of the present invention, and common knowledge such as the specific structure and / or characteristics of the scheme is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the structure of the present invention, several variations and improvements can be made, which should also be regarded as the scope of protection 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.
