Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a construction joint covering device. Background Technology

[0002] During the construction of a building project, a construction joint is usually required between two independent and adjacent buildings. After the main structure of the building is completed, the construction joint needs to be filled and smoothed. Usually, rock wool boards are filled into the construction joint and then covered with a cover plate. However, the filling and sealing effects are poor. As the relative displacement between the buildings occurs, cracks are likely to appear on the exposed surface, affecting the appearance of the building. Summary of the Invention

[0003] The present invention is made to solve the above-mentioned technical problems. Its purpose is to provide a construction joint covering device, which has a good sealing effect after being installed at the construction joint and is not easily damaged during use.

[0004] To achieve the above objectives, the present invention provides a construction joint covering device, comprising: a mounting base fixed to the main structure on both sides of the construction joint; a mounting pad fixed to the outer end of the mounting base, having a first groove parallel to the length direction of the construction joint, the opening of the first groove facing outward and the width of the opening being smaller than the width inside the first groove; a sealing plate having a first sealing strip slidably fitted into the first groove on its inner side, and a mounting hole at its end; and a mounting bolt passing through the mounting hole, one end connected to the mounting base, and the other end forming an abutment portion with a diameter larger than the diameter of the mounting hole, wherein the main body diameter of the mounting bolt is smaller than the diameter of the mounting hole.

[0005] Preferably, after the sealing plate is connected to the mounting base, the side of the first seal away from the first groove abuts against the inner side of the sealing plate.

[0006] Preferably, the side of the first seal away from the first groove is fixed to the inner side of the sealing plate.

[0007] Preferably, it further includes: a slide rail, which is fixed laterally to the inner side of the sealing plate; wherein a second slide groove is formed on the first sealing strip that is slidably connected to the slide rail.

[0008] Preferably, the sealing plate has side plates extending toward the mounting base on both sides, and an adjusting bolt is rotatably provided in the side plate, the front end of the adjusting bolt being threadedly connected to the first sealing strip.

[0009] Preferably, it further includes: a second seal, disposed between the two first seals, with a third groove slidably fitted into the slide rail on one side along its length.

[0010] Preferably, the outer end width of the slide rail is greater than the root width, and the opening width of the second and third slide grooves is smaller than the inner width.

[0011] Preferably, the first seal, the second seal, and the mounting pad are made of flexible material.

[0012] Preferably, one side of the second seal has a protrusion extending into the construction joint.

[0013] Preferably, the cross-section of the first groove is a four-pointed star shape.

[0014] Based on the above description and practical experience, the sealing plate in the construction joint covering device of the present invention is connected to the mounting seats fixed on both sides of the construction joint via mounting bolts, a first sealing strip, and mounting pads, thus achieving a good sealing effect on the construction joint. Furthermore, since the mounting bolts and the sealing plate can move relative to each other, and the first sealing strip and the mounting pad can also move relative to each other, the construction joint covering device can still maintain a good sealing effect even when relative displacement occurs between the main structures on both sides of the construction joint, and will not easily tear, thus avoiding damage and improving its service life.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0032] This disclosure provides a construction joint covering device, which is installed on the construction joint 2 between two main building structures 1 to cover the construction joint 2 and achieve a sealing effect. Figure 1The structure of the construction joint covering device in use is shown, with only a portion of the main structure 1 and a shorter section of the covering device displayed. In practical applications, the length of the construction joint covering device can be appropriately increased according to the length of the construction joint 2, or multiple covering devices can be assembled together to completely cover the construction joint 2.

[0033] Specifically, the construction joint covering device includes parts fixed to the main structure 1 on both sides of the construction joint 2, such as mounting base 3 and mounting pad 4; and removable parts, such as sealing plate 5 and its sealing strip. Please refer to [reference needed]. Figures 1 to 6 In this embodiment, the construction joint covering device includes two mounting seats 3 and two mounting pads 4. The two mounting seats 3 are respectively fixed to the main structure 1 on both sides of the construction joint 2, for example, by bolting or riveting. The mounting pads 4 are fixed to the outer ends of the mounting seats 3 for connection with the sealing strip. A first groove 6 parallel to the length direction of the construction joint 2 is provided on the mounting pad 4, and the opening of the first groove 6 faces outward and the width of the opening is smaller than its inner width. See details. Figure 5 The width of the lower port of the first chute 6 is smaller than the width of its middle part. When the seal is inserted into it, it can only move along the length and will not move in other directions.

[0034] The end of the sealing plate 5 is provided with a mounting hole 7. A mounting bolt passes through this mounting hole 7 and is connected at one end to the mounting base 3, thus connecting the sealing plate 5 and the mounting base 3. It should be noted that the other end of the mounting bolt forms an abutment portion with a diameter larger than that of the mounting hole 7, and the main body diameter of the mounting bolt is smaller than that of the mounting hole 7. In other words, the mounting bolt can limit the sealing plate 5 along its own length, preventing it from moving away from the mounting base 3, but it does not restrict the movement of the sealing plate 5 in a direction perpendicular to the mounting bolt. Therefore, when relative movement occurs between the two main structures 1 due to external factors such as temperature or settlement, relative movement can occur between the sealing plate 5 and the mounting bolt along the surface direction of the main structure 1, reducing the probability of deformation or tearing of the sealing plate 5, i.e., making it less prone to cracking.

[0035] The inner side of the sealing plate 5 is provided with a first sealing strip 8, one side of which is slidably fitted into the first groove 6. Please refer to... Figure 4 The first seal 8 has a connecting portion 9 on its side that matches the shape of the first groove 6. The first seal 8 is inserted into the first groove 6 through this connecting portion 9 to achieve a sliding assembly with the mounting pad 4. The first seal 8 and the sealing plate 5 can be either slidably connected or fixedly connected. When they are slidably connected, after the sealing plate 5 is connected to the mounting base 3, the side of the first seal 8 away from the first groove 6 abuts tightly against the inner side of the sealing plate 5, providing a good sealing effect. When they are fixedly connected, the sealing effect of this construction joint covering device is even better.

[0036] In addition, when the two main structures 1 move relative to each other due to external factors such as temperature and settlement, the relative movement is usually mainly vertical. Since the first seal 8 and the mounting pad 4 are slidably connected, they can produce vertical relative displacement, which can reduce the probability of damage to the two and the sealing plate 5, thereby improving the service life of the construction joint shielding device and making it less prone to damage during use.

[0037] It should be noted that the above-mentioned first seal 8 and mounting pad 4 mainly improve the sealing effect of the left and right sides of the construction joint covering device, while the upper and lower ends of the construction joint covering device can be directly abutted against the building or sealed by other existing sealing materials.

[0038] In this embodiment, the first seal 8 and the sealing plate 5 are slidably connected. Specifically, a slide rail 10 is fixedly provided laterally on the inner side of the sealing plate 5, and a second groove 11 is formed on the first seal 8 to slidably connect with the slide rail 10. In actual use, before installing the sealing plate 5, the distance between the two first seals 8 on the sealing plate 5 can be adjusted according to the spacing between the two mounting pads 4, so that the first seal 8 fits the mounting pad 4. When the slide rail 10 is not provided, before installing the sealing plate 5, the first seal 8 can be inserted into the mounting pad 4 first, and then the sealing plate 5 can be tightened against the first seal 8 with mounting bolts, which can also achieve the above-mentioned blocking and sealing effect.

[0039] Furthermore, in this embodiment, the sealing plate 5 is U-shaped, with side plates 12 extending towards the mounting base 3 on both the left and right sides. An adjusting bolt 13 is rotatably mounted in each side plate 12, and the front end of the adjusting bolt 13 is threadedly connected to the first sealing strip 8. In actual use, by rotating the adjusting bolt 13, the first sealing strip 8 can move along the length of the adjusting bolt 13, i.e., move left and right along the slide rail 10, facilitating user adjustment of the position of the first sealing strip 8. Alternatively, the adjusting bolt 13 can also be configured to slide within the side plate 12; by sliding the adjusting bolt 13, the horizontal position of the first sealing strip 8 can also be adjusted. In addition, the side plate 12 provides some protection for the internal first sealing strip 8 and mounting pad 4, preventing them from being exposed to wind, sun, and rain, thereby improving their service life.

[0040] In addition, in this embodiment, a second seal 14 is provided between the two first seals 8, and the second seal 14 has a third groove that is slidably fitted into the slide rail 10 along its length. Please refer to Figure 3 and Figure 4 The second seal 14 is located at the upper and lower ends of the sealing plate 5. When the sealing plate 5 is installed on the mounting base 3, the two second seals 14 abut against the mounting base 3 and the main structure 1, which can achieve the effect of sealing the upper and lower ends.

[0041] Furthermore, in this embodiment, the outer width of the slide rail 10 is greater than the root width, and the opening width of the second slide groove 11 and the third slide groove is less than the inner width. Therefore, when the first seal 8 and the second seal 14 are slidably assembled at both ends of the slide rail 10, they will not easily fall off, which can improve the stability of the construction joint covering device during use to a certain extent.

[0042] In addition, in this embodiment, the first seal 8 and the second seal 14 are both made of flexible materials, such as rubber and silicone, which can withstand a certain degree of deformation during use, further improving the tear resistance of the construction joint covering device.

[0043] In addition, in this embodiment, a protrusion extending into the construction joint 2 is provided on the side of the second seal 14, which can further improve the sealing performance of the construction joint shielding device.

[0044] Furthermore, in this embodiment, the cross-section of the first groove 6 is a four-pointed star, and correspondingly, the connecting part 9 on the first seal 8 is also a four-pointed star. This shape of the first groove 6 and the connecting part 9 can improve the stability and sealing of the connection between the first seal 8 and the mounting pad 4.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
