Description

Technical Field

[0001] The present invention relates to the technical field of wall panel connection structures, in particular to a wall panel connection structure. Background Art

[0002] In building construction, building walls are an important part. In order to improve the connection between wall panels and the main body of the building, wall panel connectors are used to reinforce the connection between them, thereby ensuring the quality and safety of the building. Traditional wall panel connectors used in construction are composed of connecting plates, fixing rods and tightening nuts. When in use, the fixing rods are pre-embedded in the wall panels and the walls of the main building. After the concrete or other building materials are fully formed, the connecting plates are matched with the fixing rods, and then the connecting plates are completely fixed by tightening the nuts and fully fit with the main building and the wall panels, thereby completing the entire reinforcement structure. The wall panel connector of this structure has the advantages of simple structure, easy use and low cost. It is currently the most widely applicable wall panel connector.

[0003] Although the existing wall panel connectors have many of the above-mentioned advantages, there are still certain limitations during use. In traditional construction methods, separate fixing rods are often embedded in concrete, or the connection between the wall panel connectors and concrete or other building materials is mainly connected through expansion screws. This causes the axial force acting on the fixing rods or expansion screws to be completely borne by the joints between the fixing rods or expansion screws and the concrete, which can easily cause the fixing rods or expansion screws to loosen and result in a loose wall connection. At the same time, drilling holes during the installation of the expansion screws may cause damage to the entire wall panel. Summary of the Invention

[0006] Furthermore, the connecting member includes a main connecting plate for connecting the first wall panel and a side connecting plate for connecting the second wall panel, and the main connecting plate and the side connecting plate are both provided with fixing holes, and the outer ends of the embedded rods are both passed through the fixing holes to the outside of the main connecting plate and the side connecting plate.

[0007] Furthermore, the circumference and thickness of the plurality of resistance plates gradually increase from inside to outside along the axial direction of the embedded rod.

[0009] Furthermore, a through hole is opened in the embedded rod along the axis and passes through the rod in a front-to-back manner. The embedded device also includes a connecting pipe, and the multiple embedded rods in the same embedded device are all connected to the connecting pipe.

[0010] Furthermore, the connecting pipe is provided with a plurality of side connecting pipes connected with the embedded rods, the inner parts of the side connecting pipes are movably sleeved with shaft sleeves, and the ends of the embedded rods are sleeved on the inner sides of the shaft sleeves.

[0011] Furthermore, the material of the shaft sleeve is wear-resistant and high-temperature resistant material.

[0012] Furthermore, the clamping member includes a fixing plate, which can completely cover the fixing hole. The fixing plate is provided with a plurality of matching holes corresponding to the embedded rods. The fixing plate is provided with an annular extrusion plate integrally formed with the connecting member on one side thereof close to the connecting member.

When the embedded rod is subjected to axial force, most of the force will act on the surface of the resistance plate in the form of shear force, thereby improving the firmness of the wall panel connection. At the same time, multiple resistance plates are arranged along the axial direction of the embedded rod, which can resist the problem of axial deformation of the embedded rod caused by large temperature difference, and avoid the phenomenon of the embedded rod being separated from the surrounding concrete due to axial deformation.

[0031] Example 1

[0032] like Figures 1-10As shown, the present invention provides a wall panel connection structure, including a first wall panel 1 and a second wall panel 2, wherein embedded devices 6 are embedded inside the first wall panel 1 and the second wall panel 2, and the embedded devices 6 include a plurality of embedded rods 61 parallel to each other. In this embodiment, the number of embedded rods 61 is set to three, and a plurality of resistance plates 62 are arranged along an axial linear array on the outside of the embedded rods 61, each resistance plate 62 is welded to three embedded rods 61, and the spacing between every two embedded rods 61 is the same. Each resistance plate 62 is perpendicular to the embedded rod 61, and a plurality of resistance plates 62 are welded to the three embedded rods 61 to form a whole; after the device is embedded, the resistance plate 62 will fit into the contacted concrete, and form a whole with the surrounding concrete after the concrete solidifies. When the embedded rod 61 is subjected to axial force, most of the force will act on the surface of the resistance plate 62 in the form of shear force. In traditional equipment, a separate fixing rod is often embedded in the concrete, which causes the fixing rod to be subjected to axial The force is completely applied at the junction between the fixing rod and the concrete, which is more likely to cause the fixing rod to loosen and the wall connection to be loose. The device involved in this application document avoids this problem very well and improves the firmness of the wall panel connection; a weak voltage is applied to one end of two adjacent embedded rods 61. At this time, the embedded rod 61 and the resistance plate 62 form a closed loop, and the array-arranged resistance plate 62 is equivalent to being connected to the closed loop in parallel. If the connection between the embedded rod 61 and the resistance plate 62 is normal and there is no break or separation, the total resistance value is small and the detected current value is large. If there is a break between the embedded rod 61 and the resistance plate 62, the total resistance value is large and the detected current value is small, thereby judging the overall working status of the embedded device 6, ensuring that the first wall panel 1 and the second wall panel 2 are in a firmly connected state, avoiding the problem that the connection between the embedded rod 61 and the wall panel is loose and cannot be observed from the outside, and reducing the detection difficulty of the device.

[0033] The circumference and thickness of the multiple resistance plates 62 gradually increase from the inside to the outside along the axial direction of the embedded rod 61. In areas with large temperature differences between day and night, the embedded rod 61 itself may undergo axial deformation due to temperature changes, and the degree of deformation increases with increasing length. In this case, the circumference and thickness of the resistance plates 62 can be continuously increased along the array direction, so that the resistance plates 62 farther away from the end face of the embedded rod 61 have stronger shear resistance, thereby counteracting the deformation of the embedded rod 61 itself, avoiding the problem of the embedded rod 61 detaching from the surrounding concrete due to frequent deformation, and improving the reliability of the device during use.

[0034] A through hole 63 is provided in the embedded rod 61 along the axis, and the embedded device 6 also includes a connecting pipe 7. Multiple embedded rods 61 in the same embedded device 6 are connected to the connecting pipe 7. In this embodiment, the number of embedded rods 61 is set to three, and the corresponding connecting pipe 7 is a three-way pipe. The connecting pipe 7 is provided with multiple side connecting pipes 71 connected to the embedded rod 61. The openings of the side connecting pipes 71 are in the same direction. The internal movably sleeve of the side connecting pipe 71 is connected with a shaft sleeve 73. The material of the shaft sleeve 73 is a wear-resistant and high-temperature resistant material such as stainless steel or molybdenum alloy. The end of the embedded rod 61 is sleeved on the inner side of the shaft sleeve 73. When a large number of fractures occur between the embedded rod 61 and the resistance plate 62, resulting in a loose connection, an alternating current with a higher voltage can be applied to one end of the embedded rod 61 in a relaxed state, and under this action, the temperature of the embedded rod 61 increases and becomes red hot, and under this action, the resistance plate 62 is re-fused with the embedded rod 61 under the action of high temperature, thereby realizing the reconnection of the embedded rod 61 and the resistance plate 62, thereby extending the service life of the device. In addition, after the fusion is completed, cooling water can be passed into the interior of the resistance plate 62 through the connecting hole 63, and the cooling water entering from the embedded rod 61 on one side is discharged from the other embedded rods 61 through the connecting pipe, thereby cooling the high-temperature embedded rod 61 and resistance plate 62, thereby avoiding excessive impact of high temperature on the strength of concrete.

[0035] A connecting piece 3 is installed at the inner corner formed by the connection of the first wall panel 1 and the second wall panel 2. The connecting piece 3 includes a main connecting plate 31 for connecting the first wall panel 1 and a side connecting plate 32 for connecting the second wall panel 2. The main connecting plate 31 and the side connecting plate 32 are formed as one piece. Reinforcing ribs are welded at the upper and lower ends of the connection between the main connecting plate 31 and the side connecting plate 32 to improve the deformation resistance of the connecting piece 3; fixing holes are opened on the main connecting plate 31 and the side connecting plate 32, and the outer ends of the embedded rods 61 pass through the fixing holes to the outside of the main connecting plate 31 and the side connecting plate 32.

[0036] The outer ends of several embedded rods 61 in the same embedded device 6 are sleeved with a compression member 5 for abutting the connector 3. The outer end of each embedded rod 61 is threadedly mounted with a fastening nut 8. After the fastening nut 8 is tightened, it fits against the outer side of the compression member 5. The compression member 5 includes a fixing plate 51, which can completely cover the fixing hole. The fixing plate 51 can then apply a pre-tightening force to the fixing plate 51 by the fastening nut 8, so that the fixing plate 51 can apply pressure to the connector 3. The fixing plate 51 is provided with a plurality of matching holes 52 corresponding to the embedded rods 61. The matching holes 52 are sleeved with the embedded rods 61 by means of axial holes. The fixing plate 51 is provided with an annular extrusion plate 53 integrally formed with the fixing plate 51 on the side near the connector 3. A plurality of filling plates 54 are axially installed on the embedded rods 61 on the outside of the first wall panel 1 and the second wall panel 2. The function of the filling plates 54 is similar to that of the butterfly springs. However, in this embodiment, the shape of the filling plates 54 is designed to be compatible with the cross-sectional shape of the inner cavity of the annular extrusion plate 53. A plurality of disc springs can also be directly sleeved on the outer end of each embedded rod 61. The disc springs are capable of bearing loads and storing a certain potential energy after being deformed under the load. When the fastening nuts become loose, the disc springs can release part of the potential energy to maintain the stability of the connection between the two wall panels. In addition, the disc springs are provided to enable the two wall panels to have the ability to buffer and absorb vibrations when connected.

[0037] During the installation of the clamping member 5, the distance between the clamping member 5 and the wall panel is reduced, and the filling plate 54 is squeezed. Under the action of squeezing, the filling plate 54 enters the interior of the annular extrusion plate 53 and fits tightly with the inner wall of the annular extrusion plate 53. At this time, by tightening the fastening nut 8, most of the reverse force on the embedded rod 61 generated by the screw-in effect will act on the filling plate 54, and only a small part will act on the embedded rod 61. When the traditional equipment tightens the fixing rod with a nut, the reverse force formed directly acts on the fixing rod and points to the outside, thereby affecting the connection structure between the fixing rod and the concrete, which is more likely to loosen during long-term use. The device involved in the present application document avoids this problem very well, and further improves the firmness of the connection of the device.

[0038] The method of use of the present invention is as follows:

[0039] During use, after the device is embedded, the resistance plate 62 will fit into the contacting concrete, and form a whole with the surrounding concrete after the concrete solidifies. When the embedded rod 61 is subjected to axial force, most of the force will act on the surface of the resistance plate 62 in the form of shear force; during installation, the fastening nut is screwed to cause the clamping member 5 to extrude and deform the filling plate 54. Under the extrusion action during the installation of the annular extrusion plate 53, the four sides of the filling plate 54 are tightly fitted with the inner wall of the annular extrusion plate 53. At this time, the fastening nut 8 is installed by screwing in the thread. Most of the reverse force on the embedded rod 61 generated by the screwing-in effect will act on the filling plate 54, and only a small part will act on the embedded rod 61.

[0040] During long-term use, the embedded rod 61 itself will undergo axial deformation due to temperature changes, and the degree of deformation increases with the increase of length. At this time, the circumference and thickness of the resistance plate 62 can be designed to continuously increase along the array direction, so that the farther the resistance plate 62 is from the inner end face of the embedded rod 61, the stronger the shear resistance effect is, thereby resisting the deformation of the embedded rod 61 itself. When detecting between the embedded rod 61 and the resistance plate 62, a weak voltage can be applied to one end of two adjacent embedded rods 61. At this time, the embedded rod 61 and the resistance plate 62 form a closed loop, and the resistance plates 62 arranged in the array are equivalent to being connected to the closed loop in parallel. If the connection between the embedded rod 61 and the resistance plate 62 is normal and no break or separation occurs, the total resistance value is small and the detected current value is large. If the embedded rod 61 and the resistance plate 62 are connected, a weak voltage can be applied to one end of the two adjacent embedded rods 61. At this time, the embedded rod 61 and the resistance plate 62 form a closed loop, and the resistance plates 62 arranged in the array are equivalent to being connected to the closed loop in parallel. If the connection between the embedded rod 61 and the resistance plate 62 is normal and no break or separation occurs, the total resistance value is small and the detected current value is large. When a break occurs between the force plates 62, the total resistance value is large and the detected current value is small, thereby judging the overall working state of the embedded device 6 and ensuring that the first wall panel 1 and the second wall panel 2 are in a firmly connected state. When a large number of breakages occur between the embedded rod 61 and the resistance plate 62 and the connection becomes loose, a high-voltage alternating current can be applied to one end of the embedded rod 61 in a relaxed state, and under this action, the temperature of the embedded rod 61 rises and becomes red-hot, and under this action, the resistance plate 62 is re-fused with the embedded rod 61 under the action of high temperature, thereby realizing the reconnection of the embedded rod 61 and the resistance plate 62, thereby extending the service life of the device. In addition, after the fusion is completed, cooling water can be passed into the interior of the embedded rod 61 through the connecting hole 63, thereby cooling the high-temperature embedded rod 61 and the resistance plate 62.
