Description

Technical Field

[0001] This invention relates to the field of building block technology, specifically to a building block that is easy to use. Background Technology

[0002] In the field of building heating, traditional wall heating systems mostly employ external exposed pipes or post-construction wall grooves for pipe installation. While external exposed pipes are simple to install, they present problems such as pipe exposure, affecting the building's aesthetics, and susceptibility to external damage. Post-construction wall grooves require secondary work after wall construction, involving cutting and chiseling to embed the pipes into the wall. This method not only requires significant manpower for repeated construction but also damages the integrity of the wall structure due to the grooving process, leading to reduced wall load-bearing capacity, increased risk of cracking, and even risks of pipe loosening and leakage due to vibration or thermal expansion and contraction. Furthermore, the construction waste and dust pollution generated from secondary grooving increase construction costs and environmental burden.

[0003] To address the aforementioned issues, existing technologies have proposed using hollow masonry blocks to embed pipes. For example, some block designs utilize the internal cavities to directly run pipes through; however, due to the lack of pipe fixing structures and the reliance on manual alignment for pipe connections, it is difficult to ensure precise alignment of adjacent pipe joints when assembling multiple blocks, resulting in low construction efficiency and a high risk of deviation. Furthermore, these blocks lack a dedicated insulation layer, leaving the pipes directly exposed within the block's internal cavity. Heat is rapidly dissipated through the outer layer of the block, failing to meet the energy-saving requirements of modern buildings. Summary of the Invention

[0004] The purpose of this invention is to provide a building block that is easy to use, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a building block that is easy to use, comprising a main layer and an inner layer; the main layer is composed of an outer layer, a reinforcing layer and an insulation layer in sequence, wherein the outer layer, the reinforcing layer and the insulation layer are positioned between layers by the cooperation of a limiting protrusion and a mating groove;

[0006] The inner layer includes an installation plate and a decorative plate. The installation plate has pre-set perforations inside, and wall heating pipe assemblies are installed in the pre-set perforations.

[0007] The wall heating pipe assembly includes a left connector, a right connector, and a connecting pipe. The left and right connectors are quickly connected by a rotating snap-fit ​​assembly. The connecting pipe is a retractable corrugated metal pipe.

[0008] The decorative panel is detachably connected to the mounting plate via a quick-release snap-fit ​​structure, and the decorative panel is equipped with push bar one and push bar two for driving the left connector to complete horizontal movement and rotation, so as to realize the automatic docking of the wall heating pipe assembly.

[0009] The mounting plate is equipped with retractable protective strips on both sides, which can be extended or retracted by pushing the component to provide shielding protection for pre-drilled holes.

[0010] Preferably, the rotating snap-fit ​​assembly includes C-shaped hooks symmetrically arranged on the outer wall of the left connector and protruding clamps on the outer wall of the right connector;

[0011] The contact end of the protruding clamp has a beveled structure. When the left connector rotates 40°, the C-shaped hook squeezes the beveled surface to drive the right connector to move horizontally, thus completing the sealing connection.

[0012] Preferably, the left connector is installed in a pre-drilled hole via a guide assembly;

[0013] The guide assembly includes a movable seat, a transverse guide rod, and a third spring. The movable seat achieves horizontal movement guidance through the transverse guide rod and the third spring.

[0014] The movable seat is provided with an upper boss, and an arc-shaped groove is opened on its inner wall to accommodate the cylindrical protrusion, and a rotational restoring force is provided by spring two.

[0015] Preferably, the pushing assembly includes an L-shaped driven rod, a cylindrical pin, and an active pressure block;

[0016] When the active pressure block is pressed, the L-shaped driven rod drives the cylindrical pin to slide along the inclined groove, driving the protective strip to extend outward to block the front side of the pre-set perforation opening.

[0017] Preferably, the bottom of the active pressing block is provided with a first magnet piece, and the bottom of the bite groove is provided with a second magnet piece with the same magnetic poles;

[0018] The active pressure block is normally positioned at the top of the bite groove by magnetic repulsion; when the protective strip is retracted, it is flush with the surface of the mounting plate, and when it is extended, it protrudes 6-9 mm to form a protective edge.

[0019] Preferably, the quick-release locking structure includes a groove, a socket, and a locking pin;

[0020] The groove is located in the middle of the mounting plate, and the locking pin is spring-loaded into the insertion hole to achieve quick fixing of the decorative panel;

[0021] The operating handle of the locking pin extends into the operating cavity of the decorative panel and is protected by a baffle.

[0022] Preferably, the mating block of the decorative panel is adapted to the groove of the mounting plate, and the upper boss is provided with a driving groove running through it from front to back.

[0023] When the mating block is inserted into the bite groove, pusher one and pusher two act on the cylindrical protrusion and the drive groove, respectively.

[0024] Preferably, the drive groove is composed of a wedge-shaped groove and a rectangular groove;

[0025] Pusher 2 enters the wedge groove first to drive horizontal movement, and pusher 1 then enters the rectangular groove to drive rotation.

[0026] Preferably, the length and height of the inner layer are both 2-4 mm greater than the main layer, so that adjacent inner layers can be seamlessly connected and gaps are reserved for the coating.

[0027] Preferably, the contact surfaces of the left and right connectors are provided with silicone sealing rings;

[0028] When adjacent blocks are spliced, the protruding clamps and C-shaped hooks are staggered; the two ends of the connecting pipe are fixed by stainless steel clamps, and the clamps are lined with high-temperature resistant rubber pads.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] 1. This invention achieves automatic and precise pipe interface docking during multi-block assembly by using pre-installed perforated embedded wall heating pipe components and a rotating snap-fit ​​assembly consisting of C-shaped hooks and protruding clamps, along with a retractable metal corrugated pipe design. Push strips one and two on the decorative panel sequentially drive the left connector to move horizontally and rotate during installation, achieving a sealed connection without manual adjustment. Simultaneously, the quick-release locking structure composed of grooves, insertion holes, and elastic pins allows for rapid assembly and disassembly of the decorative panel and mounting plate, significantly reducing pipe laying and maintenance time and effectively improving construction efficiency compared to traditional trenching and pipe embedding or manual adjustment methods.

[0031] 2. Traditional construction requires secondary trenching for pipe installation, which can easily damage the load-bearing structure of the wall and cause cracks. This invention uses pre-installed perforated integrated pipes, allowing pipe installation to be completed directly during masonry construction, completely eliminating trenching work. The main layer adopts a composite structure of an outer layer, a reinforcement layer, and an insulation layer. The layers are positioned by limiting protrusions and butt joint grooves, increasing the overall strength by more than 30%. The inner layer is 2-4 mm longer and higher than the main layer, ensuring seamless splicing of adjacent blocks and providing gaps for the coating, further preventing structural stress concentration.

[0032] 3. The wall heating pipe assembly achieves precise guidance and automatic reset through a guide component consisting of a movable seat, a horizontal guide rod, and a spring, and a rotary reset mechanism consisting of an arc-shaped sliding groove, a cylindrical protruding rod, and a spring. With the help of silicone sealing rings and stainless steel clamps for fixation, it effectively resists pipe displacement caused by construction vibration and thermal expansion and contraction. In addition, the decorative panel can be quickly removed, and after exposing the pre-drilled holes, single pipe sections can be directly inspected or replaced without damaging the wall, effectively reducing maintenance costs.

[0033] 4. The gradient composite design of the insulation layer, reinforcement layer, and outer layer in the main structure, combined with the contact isolation between the inner layer and the insulation layer, forms multiple thermal resistance barriers, significantly reducing heat loss through the blocks. Compared to traditional hollow blocks, the thermal conductivity of the wall in this invention is reduced, and the cold bridge effect is essentially eliminated. Simultaneously, the retractable protective strip extends outward during construction to form a protective edge, preventing pre-installed perforations from being blocked by paint, ensuring effective isolation between pipes and the insulation layer, further improving the overall energy efficiency of the building and meeting green energy-saving standards.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1 to 11 This invention provides a technical solution: a user-friendly building block, comprising a main layer and an inner layer 4. The main layer includes an outer layer 1, a reinforcing layer 2, and an insulation layer 3. Each of the reinforcing layer 2, insulation layer 3, and inner layer 4 has a protruding limiting ridge 7 on the side closest to the outer layer 1. Each of the outer layer 1, reinforcing layer 2, and insulation layer 3 has a mating groove 8 on the side closest to the inner layer 4 to accommodate the limiting ridge 7. The outer layer 1 is a steel fiber reinforced concrete layer, the reinforcing layer 2 is a carbon fiber mesh layer forming a transition gradient with the outer layer 1 and insulation layer 3, and the inner layer 4, on the side closest to the outside, contacts the insulation layer, thus providing a certain degree of isolation and protection for the wall heating pipe assembly. Effectively delays heat loss to the outside; the inner layer 4 includes an installation plate 5 and a decorative plate 6. The decorative plate 6 is fixed to the installation plate 5 by a quick-release assembly; the installation plate 5 has a pre-set perforation inside, and a wall heating pipe assembly is installed in the pre-set perforation. The wall heating pipe assembly includes a left connector 12, a connecting pipe 23 and a right connector 24. The right connector 24 is slidably installed at the right end of the pre-set perforation. The left connector 12 is rotated and snapped to the adjacent right connector 24 by a snap-fit ​​assembly; the connecting pipe 23 is a retractable metal corrugated pipe, and its two ends are detachably fixed to the left connector 12 and the right connector 24 by clamps in sequence.

[0048] like Figures 5-8As shown, the snap-fit ​​assembly includes a C-shaped hook 13 and a protruding clamp 25. Two sets of C-shaped hooks 13 are provided and are centrally symmetrically arranged on the outer wall of the left connector 12. Two sets of protruding clamps 25 are provided and are centrally symmetrically arranged on the outer wall of the right connector 24. The end of the protruding clamp 25 that abuts against the C-shaped hook 13 is provided as an inclined surface. When the left connector 12 and the right connector 24 are disconnected, the adjacent C-shaped hooks 13 and the raised clamps 25 are staggered. When the left connector 12 needs to be connected with the right connector 24, the left connector 12 is rotated 40°. During this process, the C-shaped hooks 13 on the left connector 12 are pressed against the inclined end of the raised clamp 25, causing the raised clamp 25 to be displaced horizontally. This causes the right connector 24 to be tightly connected with the adjacent left connector 12. A silicone sealing ring is provided on the side of the left connector 12 that contacts the right connector 24, further enhancing the tightness of the connection between the left connector 12 and the right connector 24.

[0049] like Figure 5 , Figure 7 as well as Figure 8 As shown, a movable seat 16 is movably sleeved on the outside of the left connector 12. The movable seat 16 is slidably installed in the pre-set perforation by a guide assembly. The guide assembly includes an upper boss 17, a transverse guide rod 18, a spring 19, and a vertical block 20. A movable groove for accommodating the upper boss 17 is opened on the left side of the pre-set perforation. The vertical block 20 is fixedly installed at the opening of the movable groove by a detachable assembly. Two sets of transverse guide rods 18 are provided, and springs are sleeved on them. One end of the transverse guide rod 18 is fixedly connected to the vertical block 20. 8 The other end is fixedly connected to the side wall of the movable groove. The two ends of the spring 3 19 are in series with the upright block 20 and the upper boss 17. The upper boss 17 has a circular through hole for accommodating the transverse guide rod 18. The lower end of the upper boss 17 is fixedly connected to the movable seat 16. The design of the upper boss 17 facilitates the assembly of the movable seat 16 and the left connector 12, while also serving as a guide and limiter, so that when the left connector 12 is docked with the right connector 24, it first moves horizontally and then rotates and engages.

[0050] like Figure 7 , Figures 9-11As shown, a cylindrical protrusion 14 is fixedly installed on the outer wall of the left connector 12. An arc-shaped groove for accommodating the cylindrical protrusion 14 is opened on the inner wall of the upper boss 17. A spring 2 15 is fixedly installed on the groove wall of the arc-shaped groove. The other end of the spring 2 15 is fixedly bonded to the cylindrical protrusion 14. A push bar 1 21 for pushing the cylindrical protrusion 14 and a push bar 2 22 acting on the upper boss 17 are fixedly installed on the decorative plate 6. A drive groove 1701 is opened through the upper boss 17 from front to back. The drive groove 1701 is composed of a wedge-shaped groove and a rectangular groove. The length of the push bar 1 21 is the same as the depth of the rectangular groove. When the decorative panel 6 is attached to the mounting plate 5, pusher 22 extends into the inclined groove before pusher 21. Under the pressure of the inclined surface, the upper boss 17 is forced to move the moving seat 16 and the left connector 12 horizontally toward the adjacent right connector 24. At this time, the outer protrusion of the C-shaped hook 13 is at the same horizontal plane as the inclined end of the protruding clamp 25, so that the C-shaped hook 13 can function normally with the protruding clamp 25. When pusher 22 moves from the inclined groove into the rectangular groove, the moving seat 16 remains stationary. At the same time, pusher 21 presses the cylindrical protrusion 14, so that the cylindrical protrusion 14 is forced to rotate the left connector 12 counterclockwise. This causes the outer protrusion of the C-shaped hook 13 to press the inclined end of the protruding clamp 25, so that the protruding clamp 25 is forced to move the right connector 24 to the right, thereby quickly docking with the left connector 12.

[0051] like Figures 1-6 As shown, to facilitate the assembly and maintenance of the inner layer 4, the length and height of the inner layer 4 are both set to be 2-4 mm greater than the length and height of the main layer. This ensures seamless connection between the inner layer 4 and its adjacent inner layers 4 while also providing an assembly gap for the paint on the main layer. Furthermore, to facilitate protection of pre-set perforations during the painting process on the surface of the main layer, a set of protective strips 26 are provided on both horizontal sides of the mounting plate 5. The protective strips 26 are driven by a push assembly to extend and retract. The push assembly includes a cylindrical pin 28, an L-shaped driven rod 29, and an active pressure block 30. The protective strips 26 have openings for accommodating cylindrical pins. The inclined groove 27 of pin 28, the protective strip 26, and the L-shaped driven rod 29 are all slidably mounted on the mounting plate 5. The mounting plate 5 has a bite groove 501 in the middle. One end of the L-shaped driven rod 29 is fixedly connected to the cylindrical pin 28, and the other end of the L-shaped driven rod 29 is fixedly connected to the active pressure block 30. The active pressure block 30 is slidably mounted in the bite groove 501. A first magnet is fixedly provided on the lower end face of the active pressure block 30. A second magnet with the same magnetic pole as the first magnet is fixedly provided on the bottom wall of the bite groove 501. Under the action of the same magnetic pole, and without the action of external force, the active pressure block 30 is always located at the upper end of the bite groove 501.

[0052] like Figures 2-5As shown, a docking block 31 is fixedly installed on the side of the decorative panel 6 near the mounting plate 5. The docking block 31 is fixedly engaged in the groove 501 by a locking structure. The locking structure includes two sets of mutually symmetrical locking pins 10 and a spring 11. The spring 11 is arranged between the two sets of locking pins 10. The locking pin 10 includes an operating handle and an arc-shaped insert. A set of insertion holes 502 for accommodating the arc-shaped insert is opened on both horizontal sides of the groove 501. The operating handle is limited and slidably installed on the decorative panel 6. An operating cavity 601 adapted to the operating handle is opened on the outer wall of the decorative panel 6. One end of the operating handle is exposed in the operating cavity 601, and the other end of the operating handle extends into the docking block 31 and is fixedly connected to the arc-shaped insert. A baffle 9 is engaged on the outside of the operating cavity 601.

[0053] In use, pressing the active pressure block 30 exposes the bite groove 501, which facilitates the worker's gripping of the block and allows the active pressure block 30 to push the L-shaped driven rod 29 downward. The cylindrical pin 28 on the L-shaped driven rod 29 acts on the inclined groove 27, causing the protective strip 26 to be forced to extend outward quickly and protrude 6-9 mm to form a protective edge, thereby protecting the two ends of the pre-set perforation. This allows the worker to easily apply cement-based adhesive to the surface of the main layer. After the application is completed, the force on the active pressure block 30 is released. Under the repulsive force of the like magnetic poles, the active pressure block 30 drives the L-shaped driven rod 29 to move upward quickly. Under the action of the cylindrical pin 28 and the inclined groove 27 again, the protective strip 26 quickly retracts into the mounting plate 5 and becomes flush with the surface of the mounting plate 5. Then, the block is attached and stacked with other blocks.

[0054] After the stacking is completed, the mating block 31 on the decorative panel 6 is aligned with the groove 501 and the mounting plate 5 for engagement. During this process, the mating block 31 is fixedly engaged in the groove 501 by the limiting action of the locking pin 10 and the insertion hole 502, thereby achieving the fitting and fixing of the decorative panel 6 and the mounting plate 5. The push bar 1 21 and push bar 22 on the decorative panel 6 act sequentially on the cylindrical protrusion 14 and the drive groove 1701. Push bar 22 extends into the inclined groove before push bar 1 21. Under the squeezing action of the inclined surface, the upper protrusion 17 is forced to move the seat 16 and the left mating joint 12. The C-shaped hook 13 moves horizontally towards the adjacent right connector 24. At this time, the outer protrusion of the C-shaped hook 13 is at the same horizontal plane as the inclined end of the protruding clamp 25. As the pusher 22 moves from the inclined groove into the rectangular groove, the moving seat 16 remains stationary. At the same time, the pusher 21 presses the cylindrical protrusion 14, causing the cylindrical protrusion 14 to be forced to rotate the left connector 12 counterclockwise. This causes the outer protrusion of the C-shaped hook 13 to press the inclined end of the protruding clamp 25, causing the protruding clamp 25 to be forced to move the right connector 24 to the right, thereby quickly docking with the left connector 12.

[0055] Secondly, unlike existing technologies, this building block allows for the inspection and replacement of pipes of each unit length during later maintenance.
