Description

Technical Field

[0001] The present invention relates to a connection structure, and more particularly to an ALC board seamless connection structure. Background Art

[0002] ALC panels are porous concrete panels made from fly ash or silica sand, cement, lime, and other raw materials, and cured with high-pressure steam. During construction design, multiple ALC panels can be spliced ​​together to serve as the primary support material for exterior walls, interior partition walls, and other structures. For safety reasons, ALC panels are often used as auxiliary panels for subsequent pouring. During the ALC panel forming process, auxiliary panels are cast as the main body, and auxiliary panels and other structures are spliced ​​together as needed. In the prior art, ALC panels are typically directly inserted into the steel structure during the laying of the steel structure to form a concrete pouring base. However, in actual use, it has been found that the construction time required for the concrete pouring operation is long. Gaps between ALC panels can cause internal foaming and damage on rainy days. Using conventional caulking agents can cause the ALC panels to expand and squeeze at high temperatures. Therefore, a seamless connection structure for ALC panels is needed that can automatically fill the gaps on rainy days to achieve a seamless connection.

[0003] In view of the above reasons, how to automatically fill the gaps on rainy days is exactly the problem considered in this application. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, an ALC board seamless connection structure is provided, which can automatically fill the fine gaps on rainy days to achieve seamless connection.

[0005] To achieve the above-mentioned object, the following technical solution is provided: an ALC board seamless connection structure, comprising a board body, a plug-in assembly, a positioning assembly, a restraining member, and a filling assembly, wherein the positioning assembly comprises a first water-absorbing resin, two symmetrical filling slots are provided on the top of the board body, a first receiving slot and a second receiving slot are provided on both sides of the board body, the first receiving slot and the second receiving slot are arranged in the same horizontal direction, the plug-in assembly is connected to the first receiving slot, the positioning assembly is connected to the second receiving slot, the filling assembly is received in the filling slot, and both ends of the restraining member are received in adjacent filling slots of the two board bodies; When installing the board, the plug-in assembly is connected to the positioning assembly on another board; After the first water-absorbing resin expands due to moisture, the first water-absorbing resin presses the plug-in assembly, and the plug-in assembly moves toward the positioning assembly on the other plate body, and the gap between the adjacent plates is reduced.

[0006] In summary, the above technical solution has the following beneficial effects: during installation, the present invention requires inserting the plug-in assembly on one plate into the positioning assembly on the adjacent plate to form a preliminary connection at one end of the plate, and then inserting the two ends of the restraining member into the filling grooves of the two adjacent plates respectively, and fixing the other ends of the two plates again, thereby forming a more secure connection. Usually, the restraining member is arranged above the plate, so a filling assembly is also provided to fill the filling groove, which can play a protective role. The first water-absorbing resin contained in the positioning component is a special material that expands significantly when exposed to water or humid air, and returns to its original shape after high-temperature drying. When the ambient humidity increases or the board becomes damp, the first water-absorbing resin absorbs moisture and begins to expand. The expanded resin generates strong lateral pressure, squeezing the positioning component in which it is located outward. Since the positioning component is fixed in the second receiving groove of the board body, and the plug-in component is fixed in the first receiving groove on the board body of the other board, the two are connected to each other through plug-in connection. Therefore, the expansion pressure pushes the board body where the plug-in component is located toward the board body where the positioning component is located. Under this driving force, the two adjacent boards move closer to each other, thereby automatically reducing the installation gap between them, thereby automatically filling the narrow gap on rainy days and achieving the purpose of seamless connection. After high-temperature drying, the gap between the two boards will be exposed due to the recovery of the first water-absorbing resin, thereby providing space for the boards themselves to expand and preventing damage caused by mutual squeezing between the boards. The automatic reduction of the gap is achieved by the plug-in assembly and the positioning assembly themselves. The force required to actually reduce the gap is not very large, so only the first water-absorbing resin is required. The plug-in assembly and the positioning assembly themselves are relatively complex, and as a pure connection structure, the strength is slightly low. Therefore, they are also used in conjunction with a restraining member and a filling assembly. The restraining member is the main load-bearing component of the connection structure and is used to fine-tune the filling of the gap. The continuous pressure generated by the expansion of the first water-absorbing resin maintains a tighter connection between the plug-in assembly and the positioning assembly. The core principle of the present invention is to utilize the property of the first water-absorbing resin in the positioning component to expand when it encounters moisture, thereby generating a thrust to push adjacent plates closer together, thereby automatically reducing and maintaining the gap between the plates. It can play a "self-adjusting" role in the gap, automatically filling the fine gap on rainy days to achieve a seamless connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments. Identical components are denoted by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom," "top," "inner," and "outer" refer to directions toward or away from the geometric center of a particular component, respectively.

[0010] Reference Figure 1-4 As shown, the ALC board seamless connection structure includes a board body 1, a plug-in component 2, a positioning component 3, a restraining member 4 and a filling component 5. The positioning component 3 includes a first water-absorbing resin 31. Two symmetrical filling grooves 11 are provided on the top of the board body 1. A first accommodating groove 12 and a second accommodating groove 13 are respectively provided on both sides of the board body 1. The first accommodating groove 12 and the second accommodating groove 13 are arranged in the same horizontal direction. The plug-in component 2 is connected to the first accommodating groove 12, the positioning component 3 is connected to the second accommodating groove 13, the filling component 5 is accommodated in the filling groove 11, and the two ends of the restraining member 4 are respectively accommodated in the adjacent filling grooves 11 of the two board bodies 1; When installing the board body 1, the plug-in component 2 is connected to the positioning component 3 on another board body 1; After the first water-absorbing resin 31 expands due to moisture, the first water-absorbing resin 31 presses the plug-in component 2 , and the plug-in component 2 moves toward the positioning component 3 on the other plate body 1 , and the gap between adjacent plates 1 is reduced.

[0011] During installation, the present invention requires inserting the plug assembly 2 on one plate 1 into the positioning assembly 3 on the adjacent plate 1 to form a preliminary connection at one end of the plate 1. Thereafter, the two ends of the restraining member 4 are respectively inserted into the filling grooves 11 of the two adjacent plate bodies 1, and the other ends of the two plate bodies 1 are fixed again, thereby forming a more secure connection. Typically, the restraining member 4 is located above the plate body 1, so a filling assembly 5 is also provided to fill the filling groove 11 for protection. The first water-absorbing resin 31 contained in the positioning assembly 3 is a special material that expands significantly when exposed to water or humid air, and returns to its original shape after high-temperature drying. When the ambient humidity increases or the board becomes damp, the first water-absorbing resin 31 absorbs moisture and begins to expand. The expanded resin generates strong lateral pressure, squeezing the positioning assembly 3 inward. Since the positioning assembly 3 is fixed in the second receiving groove 13 of the board body 1, and the plug-in assembly 2 is fixed in the first receiving groove 12 of the board body 1 of the other board, the two are connected by plugging. Therefore, the expansion pressure pushes the board body 1 where the plug-in assembly 2 is located toward the board body 1 where the positioning assembly 3 is located. The two adjacent boards 1 are driven together by this force, automatically reducing the existing installation gap between them, thereby automatically filling the gap on rainy days and achieving the purpose of seamless connection. After high-temperature drying, the gap between the two boards 1 will be exposed due to the recovery of the first water-absorbing resin 31, providing space for the boards 1 to expand themselves and preventing damage caused by mutual compression between the boards 1. The automatic reduction of the gap is achieved by the plug-in assembly 2 and the positioning assembly 3 themselves. The force required to actually reduce the gap is not very large, so only the first water-absorbing resin 31 is required. The plug-in assembly 2 and the positioning assembly 3 are inherently complex, and as a purely connecting structure, their strength is slightly low. Therefore, they are also used in conjunction with the restraining member 4 and the filling assembly 5. The restraining member 4 serves as the main load-bearing component of the connecting structure and is used to fine-tune the filling of the gap. The continuous pressure generated by the expansion of the first water-absorbing resin 31 maintains a tighter connection between the plug-in assembly 2 and the positioning assembly 3. The core principle of the present invention is to utilize the property of the first water-absorbing resin 31 in the positioning component 3 to expand when it encounters moisture, thereby generating a thrust to push the adjacent plates 1 closer together, thereby automatically reducing and maintaining the gap between the plates, and can play a "self-adjusting" role in the gap, automatically filling the fine gap on rainy days to achieve seamless connection.

[0012] Furthermore, the plug-in assembly 2 also includes a mounting plate 21, a connecting member 22 and a resistance ring 23. The mounting plate 21 is fixedly connected to the plate body 1. The mounting plate 21 is provided with an opening 211 connected to the first accommodating groove 12. The two ends of the connecting member 22 are respectively fixedly connected to the resistance ring 23 and the mounting plate 21. The resistance ring 23 is used to resist the inner wall of the second accommodating groove 13.

[0013] Furthermore, the connecting member 22 is made of a tough material and is provided with a fold 24 for guiding the connecting member 22 to bend outwards; When the mounting plate 21 moves toward the positioning assembly 3, the connecting member 22 and the abutting ring 23 are both accommodated in the second accommodating groove 13, the abutting ring 23 abuts against the inner wall of the second accommodating groove 13, and the connecting member 22 bends along the fold 24; After the first water absorbing resin 31 is affected by moisture and expands, the first water absorbing resin 31 presses the bent connecting piece 22 .

[0014] When the plug-in component 2 and the positioning component 3 need to be plugged in, the mounting plate 21 starts to move toward the positioning component 3. During the movement, the connector 22 and the resistance ring 23 at its end enter the second receiving groove 13 together. When the resistance ring 23 contacts the inner wall of the second receiving groove 13, a resistance force is generated. Since the connector 22 is made of a tough material and is provided with a preset fold 24, this resistance force will guide the connector 22 to bend outward along the fold 24. The bent connector 22 will prevent the two plate bodies 1 from separating, and the first water-absorbing resin 31 will squeeze the bent connector 22 after swelling due to moisture, so that the two bodies are close to each other.

[0015] Furthermore, the positioning assembly 3 further includes a screw rod 32 and a slider 33. The screw rod 32 is fixedly connected to the inner wall of the second receiving groove 13. The slider 33 is slidably connected to the screw rod 32. The two ends of the first water-absorbing resin 31 are respectively fixedly connected to the slider 33 and the inner wall of the second receiving groove 13. After the first water-absorbing resin 31 is affected by moisture and expands, the first water-absorbing resin 31 drives the slider 33 to move, and the slider 33 drives the bent connecting member 22 to move through the friction.

[0016] Furthermore, the filling assembly 5 includes a vertical filling piece 51 and a horizontal filling piece 52. The restraining piece 4 is "U"-shaped, and a through groove 41 is provided at both ends of the restraining piece 4. The two ends of the restraining piece 4 are detachably connected to different vertical filling pieces 51, and the middle of the restraining piece 4 is detachably connected to the horizontal filling piece 52. The vertical filling piece 51 is provided at the end of the restraining piece 4 away from the through groove 41, and the two ends of the restraining piece 4 are respectively accommodated in different filling grooves 11.

[0017] Furthermore, the filling assembly 5 further includes a second water-absorbing resin 53, which is fixedly connected to the through groove 41 and abuts against the inner wall of the filling groove 11; After the second water-absorbing resin 53 expands due to moisture, the second water-absorbing resin 53 presses the restraining member 4 , and the adjacent plates 1 move closer to each other, and the gap between the adjacent plates 1 decreases.

[0018] The second water-absorbing resin 53 operates on the same principle as the first water-absorbing resin 31. When exposed to moisture, the second water-absorbing resin 53 significantly expands in volume, exerting strong extrusion forces in two directions: one on the inner side walls of the restraining member 4 and the other on the inner wall of the filling slot 11. The restraining member 4 itself is difficult to deform, so under the pressure of the second water-absorbing resin 53, the two plates 1 tend to slightly shift inward at their ends toward the inside of the U-shape, that is, move closer to each other. The adjacent plates 1 are pulled closer together, and the gap between them is reduced. The vertical filling piece 51 and the horizontal filling piece 52 are used to fill the space of the filling groove 11, which can make the connection between the imprisonment piece 4 and the plate body 1 tighter and also protect the imprisonment piece 4.

[0019] Furthermore, a receiving channel 14 and a third water-absorbing resin 141 are further provided in the plate body 1 . The filling groove 11 , the first receiving groove 12 and the second receiving groove 13 are all connected to the receiving channel 14 . The third water-absorbing resin 141 is provided in the receiving channel 14 .

[0020] The third water-absorbing resin 141 is different from the first water-absorbing resin 31 and the second water-absorbing resin 53. It mainly plays the role of maintaining internal humidity. In actual construction, deformation of the plate body 1 caused by high temperature is relatively rare, so it is actually necessary to maintain a seamless state for a long time. However, the moisture in the first water-absorbing resin 31 and the second water-absorbing resin 53 will still evaporate naturally. Therefore, the third water-absorbing resin 141 is provided to absorb a large amount of moisture, thereby maintaining the water-absorbing state of the first water-absorbing resin 31 and the second water-absorbing resin 53. Only under long-term or extremely high-temperature drying conditions will the first water-absorbing resin 31 and the second water-absorbing resin 53 lose a large amount of water and recover, in order to cope with the possible deformation of the plate body 1.

[0021] Furthermore, the plug-in assembly 2 further includes a fourth water-absorbing resin 25 , which is disposed in the first receiving groove 12 .

[0022] The function of the fourth water-absorbing resin 25 is different from that of the first water-absorbing resin 31, the second water-absorbing resin 53 and the third water-absorbing resin 141. It is only used to fill the bent portion of the connector 22. Since a certain amount of redundancy needs to be left during installation of the plug-in component 2 and the positioning component 3, and this redundancy will cause internal voids after installation, which greatly affects the stability of the connection in rainy days, the fourth water-absorbing resin 25 is provided to fill the internal voids.

[0023] Furthermore, the plate body 1 also includes a first connecting channel 15, a first blocking member 151 and a first spring 152. The first connecting channel 15 connects the filling groove 11 and the second accommodating groove 13. The first blocking member 151 is used to block the connection between the second accommodating groove 13 and the accommodating channel 14.

[0024] Furthermore, the plate body 1 also includes a second connecting channel 16, a second blocking member 161 and a second spring 162. The second connecting channel 16 connects the filling groove 11 and the first receiving groove 12. The second blocking member 161 is used to block the connection between the first receiving groove 12 and the receiving channel 14.

[0025] In order to prevent the first water-absorbing resin 31 and the fourth water-absorbing resin 25 from expanding due to liquid inflow during installation, which would make it impossible to install the plug-in assembly 2 and the positioning assembly 3 normally, the first blocking member 151 and the second blocking member 161 are provided to cut off the main flow path of the liquid.

[0026] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, various improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
