Description
TECHNICAL FIELD
[0001] The utility model relates to roof expansion joint treatment technical field, concretely is a waterproof roof expansion joint structure. BACKGROUND
[0002] Roof expansion joint is expansion joint, it is the proper position setting of a structural joint along the construction joint direction of building or structure for preventing the building component due to climate temperature thermal expansion and cold shrinkage changes, make structure crack or damage, expansion joint is the building component above the foundation such as wall, floor, roof etc.
[0003] In actual roof expansion joint structure, the situation of leaking and seepage easily appears, its main reason includes two situations, one is that expansion joint structure and roof panel exist connecting gap, thereby leading to connecting gap seepage, two is when rain is too big or roof drainage is not in time, rain overflows expansion joint structure, rain will enter expansion joint, and water stop band is arranged in expansion joint in time, but the entered rain cannot be discharged in time in short time, still slowly seep into roof panel. UTILITY MODEL CONTENTS
[0004] The utility model discloses a waterproof roof expansion joint structure to solve the problem in the background art.
[0005] To achieve the above object, the utility model provides the following technical scheme: a waterproof roof expansion joint structure, which comprises a roof panel, a connecting plate, a rubber water stop strip, a top plate and a hot melt coil.
[0006] Further, the top plate is inclined downward on both sides and in contact with the upper end surface of the roof panel.
[0007] Further, the connecting plate is uniformly provided with a water passage slot on the upper end surface, and the lowest part of the water passage slot is flush with the height of the two ends of the rubber water stop strip.
[0008] Compared with the prior art, the waterproof roof expansion joint structure has the advantages that the two means are used to solve the water seepage and leakage problems of the roof expansion joint, the connecting clamping plates are arranged at the side end faces of the roof panels, the connecting clamping plates comprise vertical plates and horizontal plates, the vertical plates are higher than the roof panels after installation, when low water accumulation occurs, rainwater cannot overflow, and the rainwater cannot enter the expansion joint, meanwhile, the connecting portions of the roof panels and the connecting clamping plates are covered by the hot melt coiled material, and the rainwater cannot seep into the expansion joint, rubber waterstop strips are arranged between the connecting clamping plates and protrude upward, when the rainwater overflows, the rubber waterstop strips can block the rainwater from entering the expansion joint, in addition, water through grooves are uniformly arranged on the connecting clamping plates, when the rainwater recedes, the water accumulation on the upper side of the rubber waterstop strips can be discharged from the water through grooves, and the water accumulation cannot slowly seep into the expansion joint, and the structure is simple and can effectively prevent the roof expansion joint from leaking and seeping.
[0009] The utility model has the advantages of simple structure, safety and effectiveness, and good use effect. BRIEF DESCRIPTION OF DRAWINGS

[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.
[0014] Please refer to Figure 1 , 2The utility model provides a waterproof roof expansion joint structure, include: roof panel 1, connecting clamping plate 2, rubber waterstop 3, roof 4, hot melt coil material 5, roof panel 1 be two, be provided with expansion joint between two roof panel 1, connecting clamping plate 2 is fixedly connected on roof panel 1 side end face, connecting clamping plate 2 include vertical board 6 and the horizontal board 7 of fixedly connected on one side of vertical board 6 are formed, wherein vertical board 6 lower part is fixedly connected on roof panel 1 side end face, and the horizontal board 7 is fixedly connected on roof panel 1 upper end face, and the horizontal board 7 upper surface is flush with roof panel 1 upper end face, rubber waterstop 3 both sides be fixedly connected in two connecting clamping plate 2 outside through the clamping groove, and the middle part of rubber waterstop 3 is extruded and protrudes upwards, roof 4 is set up in the top of two connecting clamping plate 2, and the top of one of connecting clamping plate 2 is fixedly connected with roof 4, and the top of another connecting clamping plate 2 is movably connected with slide 9 and slide groove 10, hot melt coil material 5 is laid on roof panel 1 upper end face after hot melting, cover the horizontal board 7 in connecting clamping plate 2 simultaneously, and the outer end of hot melt coil material 5 is fixedly connected on the upper outside of connecting clamping plate 2 vertical board 6.
[0015] The connecting clamping plate 2 is arranged on the side end face of the roof panel 1, the connecting clamping plate 2 includes the vertical board 6 and the horizontal board 7, the vertical board 6 is higher than the roof panel 2 after installation, when lower water accumulation occurs, rainwater cannot overflow, and the rainwater cannot enter the expansion joint, meanwhile, the connecting part of the roof panel 1 and the connecting clamping plate 2 is covered by the hot melt coil material 5, and the rainwater cannot penetrate into the expansion joint, and the rubber waterstop 3 is arranged between the connecting clamping plates 2 and protrudes upwards, when the rainwater overflows, the rubber waterstop 3 blocks the rainwater from entering the expansion joint.
