Description

Technical Field

[0001] This invention relates to the field of prefabricated wall technology, and more particularly to a prefabricated laboratory functional wall for laboratory renovation. Background Technology

[0002] Laboratory functional walls refer to simple walls in laboratories that have specific functions and can meet the needs of experimental teaching, scientific research and other aspects. They include display functional walls, storage functional walls, safety functional walls, interactive functional walls, sound insulation and noise reduction walls, etc.

[0003] Display walls, storage walls, security walls, interactive walls, and soundproofing walls are all simple walls assembled from prefabricated special panels, with different accessories added according to their respective functional requirements.

[0004] Patent publication number CN117266420A discloses a building curtain wall with ventilation and heat dissipation functions, relating to the field of building curtain wall technology. The invention includes an inner curtain wall panel; a recessed structure surrounding the front of the inner curtain wall panel; an outer curtain wall panel with the same main body shape as the inner curtain wall panel and symmetrically arranged, forming a recessed space between the outer and inner curtain wall panels; a top strip fixedly installed on the top of the inner curtain wall panel; a scissor mechanism disposed within the recessed space between the inner and outer curtain wall panels; and a fan assembly providing efficient heat dissipation. The scissor mechanism can expand the outer curtain wall panel outwards, while simultaneously pushing and expanding a rotating shielding plate outwards to provide a shielding function. The rotating side plate automatically rotates and unfolds to both sides as the outer curtain wall panel moves, allowing the fan assembly to input outside air into the gap between the inner and outer curtain wall panels, achieving continuous heat dissipation and solving the problem of poor heat exchange efficiency in existing curtain walls.

[0005] The existing technology has the following drawbacks:

[0006] During wall installation, ground stakes need to be planted first, and then the panels are erected on the ground using the ground stakes. Multiple erected panels are spliced ​​together to form a wall. In actual work, due to the relatively rough measuring and drilling tools, and the influence of the environment and the skills of the workers, the holes drilled, i.e. the planting positions, will inevitably have some deviation. Workers need to push, pull, and bend the ground stakes or panels to match the assembly holes of the panels with the ground stakes. This makes the installation of the panels troublesome and time-consuming. At the same time, this installation method causes a large amount of initial stress to accumulate between the panels and the ground stakes. After a period of time, this may cause the panels or ground stakes to deform or loosen. This situation will be more obvious when the materials expand and contract due to temperature changes. Summary of the Invention

[0007] Given the inconvenience of installation in existing technologies, a prefabricated laboratory functional wall for laboratory renovation is proposed.

[0008] This application provides a prefabricated laboratory functional wall for laboratory renovation, the purpose of which is to facilitate installation.

[0009] The technical solution of the present invention is as follows: a prefabricated laboratory functional wall for laboratory renovation, comprising wall panels arranged and assembled according to a set path, two pairs of symmetrical bottom holes opened at the bottom of the wall panels, and a bottom fixing unit, wherein the bottom fixing unit specifically includes a fixing component disposed at the bottom of the wall panel, two ground bolts disposed inside the fixing component, and an offset component disposed between the fixing component and the ground bolts to control the offset of the ground bolts.

[0010] The fixing component is fixed to the ground and confines the ground bolt and offset component inside it. The ground bolt extends out of the fixing component and is inserted into the bottom socket. The wall panel is divided into a metal layer, a blocking layer and a filling layer from the outside to the inside.

[0011] Furthermore, the fixing component specifically includes a ground box attached to the ground, a cover plate disposed on the top of the ground box, a through hole opened on the surface of the cover plate, a fixing block disposed inside the ground box, a fixing hole opened on the top of the fixing block, and a grounding bolt disposed inside the fixing hole.

[0012] The grounding bolt extends through the through hole, the diameter of which is larger than the diameter of the grounding bolt. The fixing hole extends to the bottom of the grounding box, and the grounding bolt extends through the fixing hole and is inserted into the ground.

[0013] Furthermore, the offset component specifically includes a mounting block disposed inside the ground box, a mounting groove formed on the top of the mounting block, and a limiting member disposed inside the mounting groove;

[0014] The mounting blocks are distributed on both sides of the fixing block, the ground bolt is inserted into the mounting groove, and the limiting member is wrapped around the head of the ground bolt.

[0015] Furthermore, the limiting component specifically includes a floor layer and an elastic bladder disposed inside the mounting groove, a partition disposed inside the elastic bladder, a connecting channel and a converging cavity disposed on the top of the floor layer, and the partition divides the elastic bladder into more than sixteen independent chambers.

[0016] The elastic bladder is located at the top of the floor layer. The elastic bladder is annular and distributed around the outer contour of the floor layer. The converging cavity is located at the center of the floor layer. The connecting channel connects the converging cavity and the independent chamber. The elastic bladder, connecting channel and converging cavity are made of flexible material. The floor layer and the partition are both made of rigid material.

[0017] Furthermore, the surface of the wall panel is provided with a limiting component, which specifically includes a through hole opened on the surface of the wall panel, a pressure rod disposed in the through hole, a sliding groove opened at the opening of the through hole, a limiting plate and a filling block disposed in the sliding groove;

[0018] The through-hole is connected to the bottom hole. One end of the pressure rod presses against the surface of the ground bolt, and the other end presses against the surface of the limiting plate. The limiting plate is slidably installed in the sliding groove.

[0019] Furthermore, the bottom of the wall panel is provided with a receiving groove, which covers the opening of the bottom insertion hole, and the fixing component is completely housed in the receiving groove.

[0020] Furthermore, the top of the ground bolt is provided with an offset groove, and an elastic gasket is provided inside the offset groove;

[0021] The offset groove and the through hole are concentrically arranged. The elastic gasket is sleeved on the outside of the ground plug. The diameter of the elastic gasket is smaller than the diameter of the offset groove. The elastic gasket is divided into upper and lower parts. The upper part is made of rubber and the lower part is made of metal.

[0022] Furthermore, the receiving groove is filled with an elastic washer, which is located at the top of the ground bolt.

[0023] Furthermore, the top of the wall panel has two symmetrical top insertion holes, and the top of the wall panel is also provided with a connecting component. The connecting component specifically includes a connecting strip set at the junction of the tops of adjacent wall panels, two sliding holes opened at the top of the connecting strip, and a fixing bolt inserted into the sliding holes.

[0024] The fixing bolt is inserted into the top socket.

[0025] Furthermore, the length of the connecting strip is greater than the distance between the two top holes on the top of the adjacent wall panel, and the sliding hole is elongated and covers the top holes.

[0026] Furthermore, the top of the wall panel is fixedly connected with a fixing buckle, and a pressure band is set above the two connecting strips, with locking holes at both ends of the pressure band;

[0027] The pressure band is pressed against the top of the fixing bolt, and the pressure band is hooked to the outside of the fixing buckle through the buckle hole.

[0028] The beneficial effects of this invention are:

[0029] 1. By setting a bottom fixing unit, the wall panel can be stably erected on the ground using a ground bolt. At the same time, an offset component is set between the ground bolt and the mounting block. If it is found that the ground bolt cannot perfectly match the bottom socket during the installation of the wall panel, the position of the ground bolt can be adjusted manually or by chamfering the bottom socket opening. This allows the ground bolt to move and compress the elastic bladder, achieving a perfect match with the bottom socket. This eliminates the need for laborious correction through the deformation of the ground bolt or the wall panel, reducing the difficulty of installation and disassembly, reducing the initial stress between the wall panel and the bottom fixing unit, and helping to extend the service life of the materials and withstand multiple disassemblies and reassemblies. After the wall panel is placed on the ground, the elastic bladder is fixed in shape after the ground bolt is pressed down, restricting the movement of the ground bolt, thus ensuring the stability of the wall panel installation.

[0030] 2. By setting elastic shims, after the wall panel is dropped, the elastic shims are pressed into the offset groove. Under the influence of gravity and friction texture, the elastic shims and the cover plate structure are more stable, and the ground bolts are more restricted, further improving the stability of the wall panel installation.

[0031] 3. By setting up connecting components, two fixing bolts and connecting strips are used to fix the spliced ​​wall panels together. When multiple wall panels are fixed together, the force can be diffused outwards when one part is under stress, making the overall installation more stable. At the same time, since the sliding hole is set as a long strip, no matter whether two adjacent wall panels are installed in parallel, perpendicular or at a special angle, the connecting strip can span across the top of the two wall panels, and the sliding hole covers the top of the two top insertion holes to achieve the connection and fixation of the two wall panels. This allows the wall panel installation to be designed arbitrarily according to the installation site, with greater freedom and adaptability to more complex places. Attached Figure Description

[0050] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0051] Example 1

[0052] Reference Figures 1-7 , Figures 10-14 The first embodiment of the present invention provides a prefabricated laboratory functional wall for laboratory renovation, including wall panels 1 assembled according to a set path, two pairs of symmetrical bottom holes 12 opened at the bottom of the wall panels 1, and a bottom fixing unit 2. The bottom fixing unit 2 specifically includes a fixing component 21 disposed at the bottom of the wall panels 1, two ground bolts 22 disposed inside the fixing component 21, and an offset component 23 disposed between the fixing component 21 and the ground bolts 22 to control the offset of the ground bolts 22.

[0053] Specifically, the wall panel 1 is made of aluminum alloy frame and covered with wood board, aluminum alloy plate or polymer plastic plate. The opening of the bottom insertion hole 12 is chamfered and the chamfer length is five millimeters. The fixing component 21 is fixed to the ground and the ground bolt 22 and the offset component 23 are confined inside it. The ground bolt 22 extends out of the fixing component 21 and is inserted into the bottom insertion hole 12. When the fixing component 21 is implanted in the ground, a laser measuring instrument is needed to measure and fix the point. The wall panel (1) is divided into metal layer, blocking layer and filling layer from the outside to the inside.

[0054] The fixing component 21 specifically includes a ground box 211 attached to the ground, a cover plate 212 set on the top of the ground box 211, a through hole 213 opened on the surface of the cover plate 212, a fixing block 214 set inside the ground box 211, a fixing hole 215 opened on the top of the fixing block 214, and a grounding bolt 216 set inside the fixing hole 215.

[0055] Cover plate 212 covers the opening above ground box 211, and the bottom of cover plate 212 is provided with a protrusion so that it is locked above ground box 211. Ground bolt 22 passes through through hole 213 and the head of ground bolt 22 fits with cover plate 212. The diameter of through hole 213 is larger than the diameter of ground bolt 22. The side wall of fixing block 214 fits with ground box 211 and the top wall of fixing block 214 fits with cover plate 212. Fixing hole 215 passes through to the bottom of ground box 211. Grounding bolt 216 passes through fixing hole 215 and is inserted into the ground. Grounding bolt 216 is specifically an expansion bolt.

[0056] The offset component 23 specifically includes a mounting block 231 disposed inside the ground box 211, a mounting groove 232 opened on the top of the mounting block 231, and a limiting member 233 disposed inside the mounting groove 232.

[0057] Mounting blocks 231 are distributed on both sides of fixing blocks 214. The top surface of limiting member 233 is flush with mounting blocks 231 and is in contact with cover plate 212. Ground bolt 22 is inserted into mounting groove 232. Limiting member 233 is wrapped around the head of ground bolt 22. The inner diameter of limiting member 233 is larger than the diameter of through hole 213.

[0058] The limiting component 233 specifically includes a floor layer 2331 and an elastic bladder 2332 disposed inside the mounting groove 232, a partition 2333 disposed inside the elastic bladder 2332, a connecting channel 2335 and a converging cavity 2336 disposed on the top of the floor layer 2331, and the partition 2333 divides the elastic bladder 2332 into more than sixteen independent chambers 2334.

[0059] The elastic bladder 2332 is located on top of the floor layer 2331 and the two are fixed by adhesive welding. The elastic bladder 2332 is annular and distributed around the outer contour of the floor layer 2331. The elastic bladder 2332 is filled with pressurized oil. The converging cavity 2336 is located at the center of the floor layer 2331. The connecting channel 2335 connects the converging cavity 2336 and the independent chamber 2334. The inner ring side of the elastic bladder 2332 is provided with continuous protrusions, and each protrusion corresponds to the independent chamber 2334. In this way, the expansion or contraction of the protrusions can be controlled according to the change of the internal pressure oil of the independent chamber 2334. The connecting channel 2335, the converging cavity 2336 and the elastic bladder 2332 are integrally formed. The elastic bladder 2332, the connecting channel 2335 and the converging cavity 2336 are made of flexible materials, such as natural rubber and nitrile rubber. The floor layer 2331 and the partition 2333 are both made of rigid materials, such as polyethylene plastic.

[0060] By setting the bottom fixing unit 2, the wall panel 1 can be stably erected on the ground using the ground bolt 22. At the same time, the offset component 23 is set between the ground bolt 22 and the mounting block 231. If it is found that the ground bolt 22 cannot perfectly match the bottom socket 12 when installing the wall panel 1, it can be manually adjusted or the position of the ground bolt 22 can be adjusted by chamfering the opening of the bottom socket 12. This allows the ground bolt 22 to move and compress the elastic bladder 2332, achieving a perfect match with the bottom socket 12. This eliminates the need for laborious correction through the deformation of the ground bolt 22 or the wall panel 1, reducing the difficulty of installation and disassembly, reducing the initial stress between the wall panel 1 and the bottom fixing unit 2, and helping to extend the service life of the material and withstand multiple disassemblies and reassemblies. After the wall panel 1 is placed on the ground, the elastic bladder 2332 is fixed in shape after the ground bolt 22 is pressed down, restricting the movement of the ground bolt 22. This ensures the stable installation of the wall panel 1.

[0061] Since functional walls are mostly used temporarily or for short periods, they need to be quick to install and inexpensive. The requirements for precision, stability and usage time are relatively low. The design of the extended bottom fixing unit 2 is simple and rough, with low processing and usage precision. It is also not easy to be damaged when disassembled and assembled in multiple places. The core component offset assembly 23 is made of rubber and plastic material, which can be integrally formed by hot die casting, resulting in low cost and easy replacement.

[0062] Specifically, the bottom of the wall panel 1 is provided with a receiving groove 11, which covers the opening of the bottom insertion hole 12. The cover plate 212 fits against the inner wall of the receiving groove 11, and the fixing component 21 is completely stored in the receiving groove 11. This allows the wall panel 1 to be in complete contact with the ground, which can improve the stability of the wall panel 1.

[0063] Specifically, the top of the ground bolt 22 is provided with an offset groove 24, and an elastic gasket 25 is provided inside the offset groove 24.

[0064] The offset groove 24 and the through hole 213 are concentrically arranged. The elastic pad 25 is sleeved on the outside of the ground bolt 22. The diameter of the elastic pad 25 is smaller than the diameter of the offset groove 24. The elastic pad 25 is divided into upper and lower parts. The upper part is made of rubber and the lower part is made of metal. The contact surfaces of the elastic pad 25 and the offset groove 24 are provided with friction texture to increase the friction between them.

[0065] By setting the elastic shim 25, after the wall panel 1 is dropped, the elastic shim 25 is pressed into the offset groove 24. Under the influence of gravity and friction texture, the elastic shim 25 and the cover plate 212 structure are more stable, and the ground bolt 22 is more restricted, further improving the stability of the wall panel 1 installation.

[0066] Specifically, the receiving groove 11 is filled with an elastic washer 26, which is located on top of the ground bolt 22. The elastic deformation of the elastic washer 26 can solve the error that occurs during equipment installation.

[0067] The surface of the wall panel 1 is provided with a limiting component 4. The limiting component 4 specifically includes a through hole 41 opened on the surface of the wall panel 1, a pressure rod 42 disposed in the through hole 41, a sliding groove 43 opened at the opening of the through hole 41, a limiting plate 44 disposed in the sliding groove 43, and a filling block 45 disposed in the sliding groove 43.

[0068] The through-hole 41 is connected to the bottom hole 12. One end of the pressure rod 42 presses against the surface of the ground bolt 22, and the other end presses against the surface of the limiting plate 44. The limiting plate 44 is slidably installed in the sliding groove 43. The upper half of the sliding groove 43 is provided with an open opening, from which the limiting plate 44 and the filling block 45 are both installed and removed.

[0069] By setting the limiting component 4, the pressure rod 42 fixes the wall panel 1 to the ground bolt 22, making the installation of the wall panel 1 more stable. At the same time, the limiting plate 44 blocks the backward movement of the pressure rod 42, thus preventing the fixation from becoming loose.

[0070] Example 2

[0071] Reference Figure 1 , Figures 8-12This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: two top insertion holes 13 are symmetrically opened on the top of the wall panel 1, and a connecting component 3 is also provided on the top of the wall panel 1. The connecting component 3 specifically includes a connecting strip 31 provided at the junction of the tops of adjacent wall panels 1, two sliding holes 32 opened on the top of the connecting strip 31, and a fixing bolt 33 inserted into the sliding hole 32.

[0072] Specifically, the length of the connecting strip 31 is greater than the distance between the two top insertion holes 13 on the top of the adjacent wall panel 1. The fixing bolt 33 passes through the sliding hole 32 and is inserted into the top insertion hole 13. The connecting assembly 3 also includes a fixing sleeve 35 inserted into the top insertion hole 13. The fixing sleeve 35 is fixed in the top insertion hole 13 by using cement, plaster or by its own deformation. The fixing bolt 33 is threadedly connected to the fixing sleeve 35.

[0073] By setting up the connecting component 3, the wall panels 1 that are spliced ​​together are fixed together using two fixing bolts 33 and connecting strips 31. When multiple wall panels 1 are fixed together, they can spread outward when one part is under stress, making the overall installation more stable.

[0074] Specifically, the connecting assembly 3 also includes a reinforcing washer 34 sleeved on the outside of the fixing bolt 33. The reinforcing washer 34 is pressed against the surface of the connecting strip 31 by the head of the fixing bolt 33. The contact surfaces of the reinforcing washer 34 and the connecting strip 31 are both provided with friction texture.

[0075] The remaining structure is the same as that in Example 1.

[0076] Example 3

[0077] Reference Figure 1 , Figures 8-12 This is the third embodiment of the present invention. The difference between this embodiment and the first embodiment is that the sliding hole 32 is elongated and covers the top insertion hole 13. The width of the sliding hole 32 is the same as the diameter of the top insertion hole 13, and the length of the sliding hole 32 is not less than three times the diameter of the top insertion hole 13.

[0078] By setting the sliding hole 32 to be elongated, the connecting strip 31 can span across the top of the two wall panels 1 regardless of whether the two adjacent wall panels 1 are installed in parallel, vertical, or at a special angle. The sliding hole 32 covers the top of the two top insertion holes 13, thereby connecting and fixing the two wall panels 1. This allows the installation of the wall panels 1 to be designed freely according to the installation site, with greater freedom and adaptability to more complex locations.

[0079] The remaining structure is the same as that in Example 2.

[0080] Example 4

[0081] Reference Figures 15-16This is the fourth embodiment of the present invention. The difference between this embodiment and the first embodiment is that: a fixing buckle 36 is fixedly connected to the top of the wall panel 1, a pressure band 37 is set above the two connecting strips 31, and a locking hole 38 is opened at both ends of the pressure band 37.

[0082] The pressure band 37 presses against the top of the fixing bolt 33, and the pressure band 37 is hooked to the outside of the fixing buckle 36 through the buckle hole 38. The pressure band 37 spans across the top of the connecting strip 31.

[0083] By setting up a pressure band 37, the path of the fixing bolt 33 can be blocked, thus preventing the fixing from becoming loose.

[0084] The remaining structure is the same as that in Example 2.

[0085] Based on embodiments 1-3, the working principle of the prefabricated laboratory functional wall for laboratory renovation of the present invention is as follows:

[0086] During installation, first place one fixing block 214 and two mounting blocks 231 into the ground box 211, so that the two mounting blocks 231 are distributed on both sides of the fixing block 214. Then, use a laser measuring instrument to measure and position on the ground and drill corresponding holes. Then, place the ground box 211 above the holes, so that the fixing hole 215 corresponds to the hole. Finally, insert the grounding bolt 216 into the fixing hole 215 and the hole, and use the grounding bolt 216 to fix the ground box 211 to the ground. Place the limiting member 233 into the mounting groove 232, and then insert the head of the ground plug 22 into the limiting member 233. Then, cover the ground box 211 with the cover plate 212 so that the ground plug 22 passes through the through hole 213. Sleeve the elastic washer 25 on the outside of the ground plug 22 and slide it down into the offset groove 24. Finally, insert the elastic washer 26 into the bottom insertion hole 12. Move the wall panel 1 and lift it above the bottom fixing unit 2. After aligning the bottom insertion hole 12 with the ground plug 22, put it down.

[0087] During the lowering of wall panel 1, the ground bolt 22 is guided by hand or the chamfer at the opening of the bottom insertion hole 12. As the ground bolt 22 moves, its head compresses the elastic bladder 2332 on the side closest to the direction of movement. The protrusion corresponding to the independent chamber 2334 is compressed, and the pressure oil inside flows into the converging chamber 2336 through the connecting channel 2335. Due to the offset of the ground bolt 22, the elastic bladder 2332 on the other side of the ground bolt 22 separates, and the protrusion corresponding to the independent chamber 2334 no longer contacts the ground bolt 22. Thus, various pressure oils in the converging chamber 2336 flow into these independent chambers 2334, causing the corresponding protrusions to swell and re-adhere to the head of the ground bolt 22. When one side is compressed, the other side swells, causing the elastic bladder 2332 to always wrap around the head of the ground bolt 22. After the ground bolt 22 is aligned with the bottom insertion hole 12, the wall panel 1 is slowly lowered, and the bottom fixing unit 2 is completely retracted into the receiving groove 11. The inner wall of the bottom insertion hole 12 is pressed down on the ground bolt 22 by the elastic washer 26. The ground bolt 22 is pressed above the connecting channel 2335 and the converging cavity 2336, blocking the flow of the connecting channel 2335 and the converging cavity 2336. The independent chambers 2334 are all independent. When the elastic bladder 2332 is compressed, the internal pressure oil has nowhere to flow and cannot deform. The bottom of the wall panel 1 is pressed above the elastic washer 25 and the cover plate 212.

[0088] After erecting the wall panels 1 one by one on the ground according to the path, first insert the fixing screw sleeve 35 into the top insertion hole 13, then place the connecting strip 31 at the junction of the top of the two wall panels 1, so that the sliding hole 32 covers the top insertion hole 13, then put the reinforcing washer 34 on the outside of the fixing bolt 33, and insert the fixing bolt 33 through the sliding hole 32 into the top insertion hole 13.

[0089] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
