Description

Technical Field

[0001] This utility model relates to the field of wall connection technology, specifically to a connection device for connecting roofs of different materials. Background Technology

[0002] Existing joint structures between concrete and metal roofs have several drawbacks in preventing leaks, primarily including insufficient sealing performance, poor material compatibility, complex construction, and difficult maintenance. Firstly, due to the different coefficients of thermal expansion of concrete and metal, their expansion and contraction differ with temperature changes, easily leading to gaps or cracks at the joint. Sealing materials cannot fully fill and adapt to these changes, resulting in leaks. Secondly, the different surface properties of concrete and metal cause traditional sealing materials to exhibit varying adhesion and durability on both materials, resulting in uneven sealing and further increasing the risk of leaks.

[0003] Conventional solutions include using highly elastic and durable sealing materials, such as polyurethane and silicone sealants, to improve sealing performance; installing expansion joints or sliding supports at joints to allow for some displacement and reduce stress concentration; and employing multi-layered sealing structures to enhance waterproofing through multiple lines of defense. However, these methods also have significant drawbacks: high-performance sealing materials are expensive, increasing operating costs; expansion joints and sliding supports have complex structures requiring precise calculations and professional construction, extending the construction period; and multi-layered sealing structures increase structural complexity and maintenance difficulty. Even with these improvements, it is still difficult to completely avoid leakage problems caused by material aging, environmental changes, and construction errors in actual use. Utility Model Content

[0004] This utility model addresses the problem of water leakage that easily occurs after long-term use when connecting concrete and metal roofs. It provides a connecting device applicable to the connection of roofs made of different materials. The specific technical solution is as follows: A connecting device for joining roofs of different materials, wherein there is a gap between the roofs to be joined, the connecting device includes: a sealing component disposed on the roof, the sealing component's vertical projection on the roof surface being able to cover the gap, the sealing component having elastic waterproof parts on both sides of the gap along its length, the total length between the elastic waterproof parts at both ends being not less than the length of the gap; and an installation component disposed between the gap, the installation component being able to apply pressure perpendicular to the roof surface to the sealing component, thereby compressing the elastic waterproof parts by the pressure.

[0005] Furthermore, the sealing assembly also includes: a connecting portion disposed on the side of the elastic waterproof part away from the gap, the connecting portion forming a cavity for housing the elastic waterproof part on the side near the gap; and locking bolts connected at both ends to the connecting portion and the mounting assembly respectively, the locking bolts gradually pressing the connecting portion toward the mounting assembly through a threaded connection, the elastic waterproof part being compressed and filling the cavity of the connecting portion.

[0006] Furthermore, the connecting part includes: an arc-shaped plate connected to the locking bolt, the cross-section of which is an upwardly convex curve; and straight plates respectively disposed on both sides of the arc-shaped plate, the straight plates being disposed on both sides of the gap, the straight plates being able to press down the elastic waterproof part when the arc-shaped plate presses down on the straight plates.

[0007] Furthermore, the connecting part also includes folded plates respectively disposed on both sides of the straight plate away from the curved plate.

[0008] Preferably, the sealing components cover the top and bottom surfaces of the roof respectively, and the mounting components are respectively set on the upper and lower sides of the gap, with each mounting component corresponding to one of the sealing components.

[0009] Preferably, the mounting assembly includes: a corner plate with one side connected to the opposite side of the gap, the other side of the corner plate connected to the roof, the corner plate having an L-shaped cross-section, and the length direction of the corner plate being the same as the length direction of the gap; slide rails respectively disposed on the opposite sides of the corner plate, the length direction of the slide rails being the same as the length direction of the corner plate; connecting rods respectively slidably connected to the slide rails, the connecting ends of the connecting rods and the slide rails forming ball heads, the ball heads being slidably connected to the slide rails; and a mounting plate hinged to the non-ball head ends of all the connecting rods, the mounting plate being perpendicular to the opposite side of the gap, the mounting plate being connected to the sealing assembly, and the center line of the mounting plate coinciding with the center line of the sealing assembly.

[0013] As can be seen from the above technical solution, this utility model has the following beneficial effects: This invention improves the sealing and waterproofing effect at the roof joints by setting a folded plate to contact the roof to form the first waterproofing structure, setting a connecting part to press the elastic waterproofing part down to the roof to form the second waterproofing structure, and setting a filling layer to always contact the opposite surface of the gap to form the third waterproofing structure.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figure 1As shown, the roof 4 connected in this embodiment of the utility model is a concrete roof 4 and a metal roof 4. Considering the phenomenon of thermal expansion and contraction of the roof 4, a gap 43 is usually left between the roof 4 that need to be connected to allow for deformation. The length of the gap 43 is the length of the roof 4 that needs to be connected.

[0019] In this embodiment, the connecting device includes: a sealing component 1 disposed on the roof 4, the vertical projection of the sealing component 1 on the roof 4 being able to cover the gap 43, the sealing component 1 having elastic waterproof parts 12 on both sides of the gap 43 along the length direction, the total length between the elastic waterproof parts 12 at both ends being not less than the length of the gap 43; and an installation component 2 disposed between the gaps 43, the installation component 2 being able to apply pressure to the sealing component 1 in the direction perpendicular to the roof 4, thereby compressing the elastic waterproof parts 12 by the pressure.

[0020] Specifically, the length of the sealing component 1 is the same as the length of the gap 43 and the same direction. The two sides of the sealing component 1 along its length are connected to the two roof surfaces 4 that need to be connected, so that the sealing component 1 can completely cover the gap 43 and thus completely connect the roof surfaces 4 of different materials, improving the waterproof effect. Secondly, the sealing component 1 contacts the roof surface 4 through the elastic waterproof part 12. The material of the elastic waterproof part 12 is preferably nitrile rubber, but other materials can be selected according to the requirements. The purpose is that it can make close contact with the roof surface 4 when compressed, thereby achieving the waterproof effect. The compression direction of the elastic waterproof part 12 is vertical. Next, the mounting component 2 is fixedly connected to the roof surface 4 and also fixedly connected to the sealing component 1. When the distance between the mounting component 2 and the sealing component 1 decreases, the sealing component 1 moves closer to the mounting component 2, thereby causing the elastic waterproof part 12 to be compressed by pressure perpendicular to the roof surface 4. This makes the elastic waterproof part 12 make close contact with the roof surface 4, forming a second waterproof structure to achieve the waterproof effect. The sealing component 1 isolates the gap 43 from the outside through the compressed elastic waterproof part 12, thereby achieving the waterproof effect.

[0021] Furthermore, the sealing assembly 1 also includes: a connecting portion 11 disposed on the side of the elastic waterproof portion 12 away from the gap 43, the connecting portion 11 forming a cavity near the gap 43 for placing the elastic waterproof portion 12; and a locking bolt 13 connected at both ends to the connecting portion 11 and the mounting assembly 2 respectively, the locking bolt 13 gradually pressing the connecting portion 11 toward the mounting assembly 2 through a threaded connection, the elastic waterproof portion 12 being compressed and filling the cavity of the connecting portion 11.

[0022] Specifically, there is a gap between the connecting part 11 and the roof 4, forming a cavity. The elastic waterproof part 12 is placed in this cavity to seal the gap between the connecting part 11 and the roof 4, thus forming a second waterproof structure and preventing rainwater from entering the gap 43 of the roof 4. Secondly, the connecting part 11 is connected to the mounting component 2 by a locking bolt 13. When the locking bolt 13 rotates and shortens the distance between them, the mounting component 2 and the roof 4 remain relatively stable. Under the tension of the locking bolt 13, the connecting part 11 gradually moves closer to the mounting component 2, thereby gripping and compressing the elastic waterproof part 12. This causes the elastic waterproof part 12 to gradually fill the cavity, thus sealing the gap between the connecting part 11 and the roof 4 and achieving a waterproof effect.

[0023] like Figure 2 As shown, the connecting part 11 includes: an arc-shaped plate 111 connected to the locking bolt 13, the cross-section of the connecting part 11 being an upward convex curve; and straight plates 112 respectively disposed on both sides of the arc-shaped plate 111, the straight plates 112 being disposed on both sides of the gap 43, when the arc-shaped plate 111 presses down on the straight plates 112, the straight plates 112 can press down on the elastic waterproof part 12.

[0024] Specifically, the middle part of the connecting part 11 is an arc-shaped plate 111, and the two sides are straight plates 112. The cross-section of the arc-shaped plate 111 is perpendicular to its length direction. The arc-shaped plate 111 connected to the top surface of the roof 4 protrudes upward, and the arc-shaped plate 111 connected to the bottom surface of the roof 4 protrudes downward. The connection position of the locking bolt 13 and the arc-shaped plate 111 is the apex of the arc-shaped plate 111, so that the connecting part 11 can move to the maximum distance of the mounting component 2, thereby allowing the elastic waterproof part 12 to be compressed to the maximum extent, thus improving the sealing and waterproofing effect of the elastic waterproof part 12; secondly The straight plates 112 on both sides of the arc plate 111 are in direct contact with the elastic waterproof part 12, so that the arc plate 111, which is tensioned by the locking nut, can apply downward pressure to the straight plate 112 through the connection point between the two, thereby causing the straight plate 112 to press down on the elastic waterproof part 12. In this embodiment, the straight plate 112 is a plane, which is in complete contact with the top surface of the elastic waterproof part 12, so that the straight plate 112 can apply downward pressure to each point of the elastic waterproof part 12 under the action of downward pressure, thereby compressing each point of the elastic waterproof part 12, thereby improving the sealing and waterproofing effect of the elastic waterproof part 12.

[0025] Furthermore, the connecting part 11 also includes folded plates 113 respectively disposed at both ends of the straight plate 112 away from the curved plate 111. The folded plates 113 are respectively connected to the straight plate 112 and the roof 4, and the straight plate 112, the folded plates 113 and the roof 4 together form a cavity.

[0026] Specifically, the curved plate 111 is symmetrically arranged on both sides of the straight plate 112 with the curved plate 111 as the center, so that the middle part of the connecting part 11 is the curved plate 111, and the straight plate 112 is connected to the two sides of the curved plate 111. The outermost part is the folded plate 113, which forms a certain angle with the straight plate 112. When the elastic waterproof part 12 is placed below the connecting part 11, the folded plate 113 can also contact the roof 4, thereby forming a cavity. When the connecting part 11 moves closer to the mounting component 2, the folded plate 113 will also apply pressure to the roof 4, thereby making the contact surface between the folded plate 113 and the roof 4 in close contact with the roof 4, forming the first waterproof structure. This allows the outer side of the connecting part 11 to first achieve a sealing and waterproofing effect, intercepting some rainwater, and then the second waterproof structure can further intercept some rainwater, thereby improving the overall sealing and waterproofing effect of the embodiment.

[0027] Furthermore, the sealing components 1 cover the top and bottom surfaces of the roof 4 respectively, and the mounting components 2 are respectively set on the upper and lower sides of the gap 43, with the mounting components 2 corresponding one-to-one with the sealing components 1.

[0028] Specifically, the two sealing components 1 completely cover the top and bottom surfaces of the roof 4, thereby enabling them to seal and waterproof both the top and bottom surfaces of the roof 4, thus preventing water vapor from entering the gaps 43 between the roof 4 in all directions and improving its waterproof effect; secondly, the installation components 2 apply tension to the sealing components 1, so that the sealing components 1 on the top and bottom surfaces of the roof 4 can achieve a good sealing and waterproof effect.

[0029] like Figure 1 and Figure 3 As shown, the mounting assembly 2 includes: a corner plate 24 with one side connected to the opposite side of the gap 43, the other side of the corner plate 24 connected to the roof 4, the corner plate 24 having an L-shaped cross-section, and the length direction of the corner plate 24 being the same as the length direction of the gap 43; slide rails 25 respectively disposed on the opposite side of the corner plate 24, the length direction of the slide rails 25 being the same as the length direction of the corner plate 24; connecting rods 22 respectively slidably connected to the slide rails 25, the connecting ends of the connecting rods 22 and the slide rails 25 forming ball heads 23, the ball heads 23 being slidably connected to the slide rails 25; and mounting plates 21 hinged to the non-ball head ends of all the connecting rods 22, the mounting plates 21 being perpendicular to the opposite side of the gap 43, the mounting plates 21 being connected to the sealing assembly 1, and the center line of the mounting plates 21 coinciding with the center line of the sealing assembly 1.

[0030] Specifically, corner plates 24 are fixedly connected at the right angles of the top and bottom surfaces of the roof 4. There are four corner plates 24. One side of the corner plate 24 contacts the roof 4, and its other vertical side contacts the opposite side of the gap 43, so that the corner plate 24 can be limited by the roof 4 in the vertical direction. The opposite surfaces of the two opposite corner plates 24 are fixedly connected to the slide rails 25. The length direction of the slide rail 25 is its sliding direction, which is parallel to the length direction of the gap 43. The trajectory formed by sliding along the sliding surfaces of the two opposite slide rails 25 is perpendicular to the opposite surface of the gap 43 and also parallel to the top and bottom surfaces of the roof 4.

[0031] Secondly, the mounting plate 21 is set between the gaps 43 and is parallel to the top surface of the roof 4. One end of the locking bolt 13 is perpendicular to and fixedly connected to the mounting plate 21, so that the connecting part 11 grips and moves closer to the mounting plate 21 under the rotation of the locking bolt 13, and its approach direction is perpendicular to the top surface of the roof 4, so that the descent distance of each point of the connecting part 11 is the same, thereby making the pressure applied by the straight plate 112 to each point of the elastic waterproof part 12 the same, and thus making the compression degree of each point of the elastic waterproof part 12 the same, ensuring its sealing and waterproofing effect. Secondly, there are four hinge interfaces evenly distributed at the four corners of the mounting plate 21. Each hinge interface is hinged to one end of the connecting rod 22, and the rotation axis of the connecting rod 22 and the mounting plate 21 is parallel to the opposite surface of the gap 43, so that the rotation trajectory of the connecting rod 22 is perpendicular to the opposite surface of the gap 43. The other end of the connecting rod 22 forms a ball head 23, and the maximum diameter of the ball head 23 is greater than the diameter of the connection between the connecting rod 22 and the ball head 23.

[0032] The ball head 23 is slidably connected to the slide rail 25, so that the movement trajectory of the connecting rod 22 connected to it is perpendicular to the opposite surface of the gap 43. That is, the plane of the movement trajectory is a horizontal plane, and the opposite surface of the gap 43 is a vertical plane. When the spacing of the roof 4, i.e. the width of the gap 43, changes, the ball head 23 of the connecting rod 22 can move along the slide rail 25, and the connecting rod 22 rotates relative to the mounting plate 21. This allows the connecting rod 22 to move closer to or away from the opposite surface of the gap 43, and the mounting plate 21 to move closer to or away from the opposite surface of the gap 43. The center line of the mounting surface always coincides with the center line of the sealing component 1. This ensures that even if the roof 4 expands and contracts due to temperature changes, causing the length of the gap 43 to change, the sealing component 1 can always cover the gap 43, and the mounting component 2 can always apply tension to the sealing component 1, thus ensuring the sealing and waterproofing effect at the joint of roofs 4 made of different materials.

[0033] Furthermore, sealing components 1 are respectively installed on the top and bottom surfaces of the roof 4, and mounting components 2 are respectively installed on the upper and lower sides of the gap 43, with each mounting component 2 corresponding to a sealing component 1.

[0034] Specifically, sealing components 1 and installation components 2 are installed on both the top and bottom surfaces of the roof 4 for sealing and waterproofing, so that both the top and bottom surfaces can be sealed and waterproofed, thereby ensuring that the joints of the roof 4 are isolated from the outside world, and thus improving the sealing and waterproofing effect of the joints of the roof 4.

[0035] Furthermore, this embodiment of the present invention also includes a filling layer 3 disposed between the mounting components 2. The filling layer 3 is connected to the opposite surface of the gap 43 and the mounting components 2 respectively. The filling layer 3 is made of a flexible material that can absorb water and keep warm.

[0036] Specifically, the opposite surfaces of the gap 43 and the mounting plates 21 on the upper and lower sides enclose a space filled with the filling layer 3. This space changes as the roof 4 expands and contracts due to heat. The filling layer 3 uses a flexible material so that it can always contact the opposite surfaces of the gap 43 when the gap 43 changes, thereby allowing the two roof surfaces 4 to deform. The filling layer 3 uses a water-absorbing material so that it can absorb the water vapor flowing into the gap 43 without affecting the deformation of the roof surface 4, thereby improving the waterproof effect of the embodiment. Secondly, it uses a thermal insulation material so that it can improve the thermal insulation effect at the joint of the roof surface 4, thereby improving the overall thermal insulation effect of the space using the roof surface 4.

[0037] Specifically, the filling layer 3 is made of thermal insulation cotton, which can ensure that it is always in contact with the gap 43 when the roof 4 deforms, absorb water, and improve the thermal insulation effect at the joint.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.

[0039] The technologies, shapes, and structures not described in detail in this utility model are all known technologies.
