Description

A detachable keel fixing device Technical Field

[0001] This invention belongs to the field of building construction technology, and more specifically, relates to a detachable keel fixing device. Background Technology

[0002] In the field of building construction, in the detailed design of fine-decorated wall drawings, steel keel is usually used as the connecting support structure of the base plate. The wall keel is generally installed and fixed perpendicular to the structural ground and structural top plate. It forms an overall load-bearing system by welding with the pre-embedded steel plate. The pre-embedded steel plate is then reliably connected to the structural floor slab and top plate by expansion bolts. This fixed node method is a relatively common wall detailing construction process in the industry.

[0003] However, this process has obvious limitations in practical applications: once the drawings are changed during the construction process, and the wall positioning or the wall position needs to be adjusted or rearranged, the wall keel that has been welded and fixed can only be removed by gas cutting or mechanical cutting. This method will not only cause irreversible damage and pollution to the keel itself, making it impossible to recycle and reuse, resulting in a lot of material waste, but will also directly affect the overall construction period of the fine decoration. The cutting operation will also bring structural damage and other safety hazards.

[0004] Therefore, the present invention provides a detachable keel fixing device. When the drawing changes and the position needs to be changed, the wall keel can be removed without cutting. The removal is convenient and saves construction time. The removed keel can also be reused, which is in line with the concept of green environmental protection. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a detachable keel fixing device.

[0006] A detachable keel fixing device includes a structural floor slab and a keel body. The upper end of the structural floor slab is provided with a fixing base plate, and the four corners of the fixing base plate are provided with first bolts to connect with the structural floor slab.

[0007] Preferably, the fixed base plate is provided with a modular fixing structure;

[0008] The modular fixing structure includes a storage slot and clamps. The keel body is located between the clamps. The storage slot is opened inside the fixed base plate. A connecting seat is provided inside the storage slot. Screws are provided at the four corners of the connecting seat to connect with the fixed base plate. The clamps are symmetrically located at the upper end of the connecting seat. A gap is left between the clamps to form a slot. The keel body is located in the slot between the clamps.

[0009] Preferably, the modular fixing structure is provided with an adaptive limiting structure, which can assist in limiting the installation of the keel body on the modular fixing structure;

[0010] The adaptive limiting structure includes limiting plates, two of which are fixedly installed on opposite ends of two clamping plates. The keel body and the clamping plates are symmetrically connected by second bolts. A limiting inner groove is formed inside the limiting plate, and a spring assembly is provided on the side wall of the limiting inner groove. An abutment plate is slidably installed inside the limiting inner groove, and the abutment plate is fixedly connected to the spring assembly. An upper wedge block is fixedly installed at the upper end of the abutment plate. A top sliding groove is symmetrically formed on the top of the limiting plate, and a slider is symmetrically fixedly installed on the side wall of the upper wedge block. The slider is slidably installed with the top sliding groove, and a wedge surface is provided on the surface of the upper wedge block.

[0011] Preferably, the modular fixing structure and the adaptive limiting structure are provided with an adjustment structure, which can adjust the adaptive limiting structure to adapt to keel bodies of different sizes;

[0012] The adjustment structure includes a side sliding groove and a transmission groove. The side sliding grooves are symmetrically opened through the fixed base plate, and the transmission groove is opened through the fixed base plate and located between the two side sliding grooves. A slide bar is fixedly installed at the lower end of the clamping plate. The slide bar is slidably installed with the side sliding groove. A transmission block is fixedly installed at the lower end of the limiting plate. A bidirectional lead screw is rotatably installed on the inner side of the fixed base plate. The bidirectional lead screw is located below the transmission groove. The transmission block is threadedly installed with the bidirectional lead screw. A slotted rotating head is provided at both ends of the bidirectional lead screw.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, a modular fixing structure is set up. The modular fixing structure can be detachably installed on the fixing base plate. The workers only need to open the corresponding storage slot on the fixing base plate, and then install the connecting seat inside the storage slot with screws to complete the assembly and fixing of the modular fixing structure. There is no need to make overall modifications to the fixing base plate, which reduces the construction difficulty in the early stage of installation. At the same time, the detachable design facilitates the later maintenance and replacement of the modular fixing structure, avoiding the trouble of having to completely disassemble the fixing base plate after the component is damaged, and improving maintenance efficiency.

[0015] In this invention, by setting an adaptive limiting structure, the keel body can be limited during installation, which assists in completing the installation. During installation, the worker only needs to align the grooves on both sides of the keel body with the position of the limiting plate and insert it. During the keel body's downward movement, the limiting plate can achieve initial positioning, avoiding offset or misalignment when the keel body is inserted. This helps the worker quickly find the installation position, makes it easier to align the screw holes, reduces the difficulty of the installation operation, and improves the accuracy and efficiency of the installation.

[0016] In this invention, by setting an adaptive limiting structure, the groove of the keel body can be tightly fitted with the limiting related components, increasing the overall installation stability. The spring group in the limiting inner groove forms an elastic connection with the abutment plate. After the keel body is inserted, the elastic force of the spring group can push the abutment plate to always fit against the inner wall of the groove of the keel body. Combined with the limiting effect of the limiting plate, it effectively alleviates the problem of shaking and displacement of the keel body after installation, ensuring the stability of the overall structure.

[0017] In this invention, by setting an adaptive limiting structure and an upper wedge, the elastic structure can be adaptively controlled to contract. When the keel body is inserted, its lower surface will actively contact the wedge surface of the upper wedge. After the wedge surface is subjected to pressure, it generates radial force. Under the limiting action of the limiting inner groove on the contact plate, the contact plate can be driven to contract into the limiting inner groove, thereby driving the spring assembly to compress and realize the adaptive contraction of the elastic structure. This ensures that the keel body can be inserted smoothly and can achieve a tight fit through elastic reset after insertion, thus improving the convenience of installation.

[0018] In this invention, by setting an adjustment structure, the size of the adaptive limiting structure can be adjusted, increasing the applicability of the device. The operator can rotate the bidirectional lead screw through the single-slot rotating head, which can drive the transmission block to slide. Then, through the linkage of the limiting plate and the clamping plate, the clamping plate moves closer or further away from each other under the cooperation of the slide bar and the side slide groove, thereby adjusting the distance between the two limiting plates. This adapts to different sizes of keel bodies, avoiding the disadvantage of traditional fixing devices that can only adapt to a single size of keel, expanding the applicability of the device, and reducing construction costs.

[0019] In this invention, by setting an adjustment structure, when it is necessary to disassemble the keel body, the worker only needs to rotate the flathead rotating head in the opposite direction, which drives the bidirectional screw to rotate in the opposite direction, thereby causing the clamps to move away from each other, so that the clamps are separated from the surface of the keel body. The worker can directly take out the keel body without disassembling other fixed parts, which simplifies the disassembly process, improves the disassembly efficiency, and the threaded transmission saves effort and reduces the operating intensity of the worker.

[0026] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0027] Please refer to Figures 1-5. The present invention provides a detachable keel fixing device, including a structural floor slab 11 and a keel body 34. A fixing base plate 12 is provided at the upper end of the structural floor slab 11, and first bolts 13 are provided at the four corners of the fixing base plate 12 to connect with the structural floor slab 11.

[0028] The fixed base plate 12 is provided with a modular fixing structure, which includes a storage slot 14 and a clamping plate 17. The keel body 34 is located between the clamping plates 17. The storage slot 14 is opened inside the fixed base plate 12. The storage slot 14 is provided with a connecting seat 15. The four corners of the connecting seat 15 are provided with screws 16 to connect with the fixed base plate 12. The clamping plates 17 are symmetrically arranged on the upper end of the connecting seat 15. There is a gap between the clamping plates 17 to form a slot. The keel body 34 is located in the slot between the clamping plates 17.

[0029] By setting up a modular fixing structure, the modular fixing structure can be detachably installed on the fixing base plate 12. The staff only needs to open the corresponding storage slot 14 on the fixing base plate 12, and then install the connecting seat 15 inside the storage slot 14 with screws 16, thereby completing the assembly and fixing of the modular fixing structure. There is no need to make overall modifications to the fixing base plate 12, which reduces the construction difficulty in the early stage of installation. At the same time, the detachable design facilitates the later maintenance and replacement of the modular fixing structure, avoiding the trouble of having to completely disassemble the fixing base plate 12 after the components are damaged, thus improving maintenance efficiency.

[0030] The modular fixed structure is equipped with an adaptive limiting structure. The limiting structure can assist in limiting the installation of the keel body 34 on the modular fixed structure. The adaptive limiting structure includes a limiting plate 18. Two limiting plates 18 are fixedly installed on the opposite ends of two clamping plates 17. The keel body 34 and the clamping plates 17 are symmetrically connected by second bolts 35. A limiting inner groove 19 is opened inside the limiting plate 18. A spring assembly 21 is provided on the side wall of the limiting inner groove 19. An abutment plate 22 is slidably installed inside the limiting inner groove 19. The abutment plate 22 is fixedly connected to the spring assembly 21. An upper wedge block 23 is fixedly installed at the upper end of the abutment plate 22. A top sliding groove 24 is symmetrically opened on the top of the limiting plate 18. A slider 25 is symmetrically fixedly installed on the side wall of the upper wedge block 23. The slider 25 is slidably installed with the top sliding groove 24. A wedge surface 26 is provided on the surface of the upper wedge block 23.

[0031] By setting an adaptive limit structure, the keel body 34 can be limited during installation, which helps to complete the installation. During installation, the staff only needs to align the grooves on both sides of the keel body 34 with the position of the limit plate 18 and insert it. The keel body 34 can be initially positioned by the limit plate 18 during the downward movement, avoiding the offset or misalignment of the keel body 34 when it is inserted. This helps the staff to quickly find the installation position, makes it easy to align the screw holes, reduces the difficulty of the installation operation, and improves the accuracy and efficiency of the installation.

[0032] By setting an adaptive limiting structure, the groove of the keel body 34 can be tightly fitted with the limiting related components, increasing the overall installation stability. The spring group 21 in the limiting inner groove 19 forms an elastic connection with the contact plate 22. After the keel body 34 is inserted, the elastic force of the spring group 21 can push the contact plate 22 to always fit against the inner wall of the groove of the keel body 34. Combined with the limiting effect of the limiting plate 18, it effectively alleviates the problem of shaking and displacement of the keel body 34 after installation, ensuring the stability of the overall structure.

[0033] By setting an adaptive limiting structure and the upper wedge 23, the elastic structure can be adaptively controlled to shrink. When the keel body 34 is inserted, its lower surface will actively contact the wedge surface 26 of the upper wedge 23. After the wedge surface 26 is subjected to pressure, it generates radial force. Under the limiting action of the limiting inner groove 19 on the contact plate 22, it can drive the contact plate 22 to shrink into the limiting inner groove 19, thereby driving the spring assembly 21 to compress, realizing the adaptive shrinkage of the elastic structure. This can not only ensure that the keel body 34 is inserted smoothly, but also achieve a tight fit through elastic reset after insertion, improving the convenience of installation.

[0034] The modular fixed structure and the adaptive limiting structure are equipped with an adjustment structure. The adjustment structure can adjust the adaptive limiting structure to adapt to the keel body 34 of different sizes. The adjustment structure includes a side sliding groove 27 and a transmission groove 28. The side sliding groove 27 is symmetrically opened through the fixed base plate 12. The transmission groove 28 is opened through the inside of the fixed base plate 12 and is located between the two side sliding grooves 27. A slide bar 29 is fixedly installed at the lower end of the clamping plate 17. The slide bar 29 is slidably installed with the side sliding groove 27. A transmission block 31 is fixedly installed at the lower end of the limiting plate 18. A bidirectional screw rod 32 is rotatably installed on the inner side of the fixed base plate 12. The bidirectional screw rod 32 is located below the transmission groove 28. The transmission block 31 is threadedly installed with the bidirectional screw rod 32. A slotted rotating head 33 is provided at both ends of the bidirectional screw rod 32.

[0035] By setting an adjustment structure, the size of the adaptive limiting structure can be adjusted, increasing the applicability of the device. The operator can rotate the bidirectional lead screw 32 through the one-slot rotating head 33, which can drive the transmission block 31 to slide. Then, through the linkage of the limiting plate 18 and the clamping plate 17, the clamping plate 17 moves closer or further apart with the cooperation of the slide bar 29 and the side slide groove 27, thereby adjusting the distance between the two limiting plates 18 to adapt to different sizes of keel bodies 34. This avoids the disadvantage of traditional fixing devices that can only adapt to a single size of keel, expands the applicability of the device, and reduces construction costs.

[0036] By setting an adjustment structure, when it is necessary to disassemble the keel body 34, the operator only needs to rotate the flathead rotating head 33 in the opposite direction, which will drive the bidirectional lead screw 32 to rotate in the opposite direction, thereby causing the clamping plates 17 to move away from each other, so that the clamping plates 17 are separated from the surface of the keel body 34. The operator can directly remove the keel body 34 without disassembling other fixed parts, which simplifies the disassembly process, improves the disassembly efficiency, and the threaded transmission saves effort and reduces the operator's operating intensity.

[0037] Working principle:

[0038] When using it, first adjust the device according to the dimensions of the keel body 34 in the drawing, and ensure that the bolts have reserved screw holes. The fixing part of the base plate 12 and the structural floor slab 11 is made of steel plate, with each side being 100mm wider than the keel body 34, the steel plate being 5mm thick, and the clear height of the slot being 100mm higher than the base plate 12.

[0039] After preparation, the staff first installs the connecting seat 15 inside the storage slot 14 of the fixed base plate 12 with screws 16, ensuring that the connecting seat 15 fits snugly against the inner wall of the storage slot 14 and is installed firmly. Then, the staff rotates the double-acting screw 32 through the slotted head 33. During the rotation of the double-acting screw 32, it engages with the transmission block 31 through the threaded transmission, causing the transmission block 31 to slide in the transmission slot 28. Since the transmission block 31 is fixedly connected to the limiting plate 18, it drives the transmission block 31 to move in conjunction with the clamping plate 17 through the limiting plate 18. At the same time, the slide bar 29 below the clamping plate 17 is embedded in the side sliding groove 27. Under the limiting and guiding action of the side sliding groove 27, the slide bar 29 drives the two symmetrically arranged clamping plates 17 to move closer to each other synchronously until the contact distance between the clamping plate 17 and the surface of the keel body 34 is less than 5mm. If it is too small, the keel body 34 cannot be inserted into the slot; if it is too large, the keel body 34 is prone to shaking and not being firmly fixed, which poses a safety hazard. At this point, the staff stops rotating the slotted head 33.

[0040] Subsequently, the workers installed the fixed base plate 12 onto the structural floor slab 11 using the first bolt 13. The single nut and matching washer of the first bolt 13 were tightened, and the bolt threads were exposed at least 10mm to ensure a stable connection.

[0041] Then, using a special tool, the keel body 34 is picked up and the grooves on both sides of the keel body 34 are precisely aligned with the position of the limiting plate 18. It is then slowly inserted into the slot formed by the limiting plate 18 and the clamping plate 17. When the lower surface of the keel body 34 slowly slides down between the two limiting plates 18, it will actively contact the wedge surface 26 of the wedge block 23. With the elastic connection between the spring group 21 inside the limiting inner groove 19 and the abutment plate 22, and under the upper and lower sliding limiting action of the limiting inner groove 19 on the abutment plate 22, the wedge surface 26 generates radial force after being pressured by the keel body 34. This radial force drives the abutment plate 22 to contract into the limiting inner groove 19. At the same time, the wedge surface 26 will actively drive the sliders 25 on both sides to slide synchronously inside the top sliding groove 24. Thus, the two side walls of the limiting plate 18 and the surface of the abutment plate 22 are always in contact with the three surfaces of the groove of the keel body 34 through the elastic force of the spring group 21.

[0042] Due to the above-mentioned elastic connection, when the clamping plate 17 is not fully attached to the surface of the keel body 34, the contact plate 22 can rely on the elastic force of the spring assembly 21 to fit tightly against the groove of the keel body 34. Then, by adjusting the structure, the clamping plate 17 is driven to move closer to the keel body 34 until the clamping plate 17 clamps the keel body 34, thus completing the initial installation operation of the keel body 34.

[0043] Finally, the workers fixed the keel body 34 to the clamp plate 17 with the second bolt 35. The front side is the bolt head of the second bolt 35, and the back side is the nut and matching washer. The bolt threads are exposed at least 10mm to achieve the complete installation of the keel body 34 and ensure the stability of the overall structure.

[0044] When disassembly is required, the second bolt 35 can be removed, and then the adjustment structure can be rotated in the opposite direction to separate the contact surface between the clamping plate 17 and the keel body 34.

Many modifications and variations will be apparent to those skilled in the art.
