Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building sealing structures, in particular to a sealing structure for connecting an exterior wall panel with the ground. Background Art
[0002] Through the use of electric curing barns in the past two years and the feedback from bakers, it is found that newly built electric curing barns have water seepage on rainy days due to different construction techniques of manufacturers, which causes visible water in the tobacco loading room. The evaporation of high-temperature water increases the humidity. When tobacco farmers are baking tobacco leaves, they suffer unnecessary losses due to poor or untimely moisture discharge.
[0003] According to the existing technical standards for electric curing rooms, after the wall panels are installed, the ground trough on one side is sealed with concrete. Whether it is an electric curing room or a biomass curing room, as long as the curing room is built with polyurethane panels, there will be problems with the connection and sealing of the wall panels and the ground.
[0004] Concrete has the property of thermal expansion and contraction, which is caused by the temperature change of the water in the concrete. When the temperature rises, the water in the concrete will expand, resulting in the expansion of the concrete volume. When the temperature drops, the water in the concrete will shrink, resulting in the contraction of the concrete volume. During the use of the electric energy curing room, it was found that after the alternation of cold and warm, the gap between the concrete and the wall panel will become larger and larger with the use time. After rainy days, the rain outside and the rain dripping from the roof panel flow down through the wall panel into the gap, and enter the curing room through penetration. As time goes by, the amount of water entering the curing room will gradually increase, further increasing the humidity of the tobacco loading room. The dehumidification of flue-cured tobacco is the largest during the late yellowing period, the color fixing period and the dry reinforcement period, which is also the most critical time for baking. The continuous high temperature and high humidity conditions in the flue-curing room will not only affect the dehumidification, but also the judgment of the baker on the baking of tobacco leaves will be different, resulting in the poor quality of tobacco leaves baked in the curing room, causing unnecessary losses to tobacco farmers. At the same time, the curing room seeps water from the bottom, which makes tobacco farmers question the supplier's construction technology and the quality of the curing room.
[0005] In order to solve the above problems, a sealing structure for connecting an exterior wall panel with the ground is proposed. Utility Model Content

[0031] Embodiment 1
[0032] In order to more clearly describe the specific structural composition and formation process of the connection and sealing structure between the exterior wall panel and the ground, the following Figure 1-4 describes this embodiment:
[0033] Referring to Figure 1 , a connection and sealing structure between an exterior wall panel and the ground includes a wall panel 1 and a ground trough 2 wrapped around the lower end of the wall panel 1. Expansion bolts 3 are arranged in the bolt holes of the ground trough 2. Both ends of the expansion bolts 3 are fixedly connected to the ground layer 4 and the wall panel 1 respectively. The ground layer 4 is generally a concrete layer, which is convenient for construction. The wall panel 1, the ground trough 2, and the ground layer 4 are connected and fixed by the expansion bolts 3. A number of wall panels 1 are spliced to form a curing barn. During this construction process, it is easy for water to seep between the wall panel 1 and the ground layer 4. Therefore, a sealing buffer belt 5, a solid seal 6, and a waterproof glue layer 7 are sequentially arranged at the corner of the wall panel 1 and the ground trough 2; that is, on the basis of the existing concrete solid seal, two waterproof measures, namely the sealing buffer belt 5 and the liquid waterproof glue (i.e., the waterproof glue layer 7), are added to achieve three-layer protection and reach the sealing effect. The overall construction cost is not high, and after the curing barn is implemented, the water seepage phenomenon can be significantly reduced, and the baking loss of tobacco farmers can be reduced.
[0034] The ground trough can be formed by bending a 1.2 mm thick hot-dip galvanized sheet, and the inner diameter is the wall panel thickness + 2 mm. The specific shape can be a "U" shape.
[0035] Referring to Figure 2 , the following specifically describes the sealing buffer belt 5, the solid seal 6, and the waterproof glue layer 7:
[0036] One side of the sealing buffer strip 5 is adhered to the stratum 4, and the other side crosses the exposed surface of the trench 2 (the exposed surface is temporary and will be covered after the construction of the sealing buffer strip 5) and adheres to the wall panel 1 on the same side; the sealing buffer strip 5 is located between the solid seal 6 and the wall panel 1 / stratum 4, and the sealing buffer strip 5 itself has deformation ability and bonding ability (bonding with the solid seal, the stratum and the wall panel). When the concrete solid seal expands and contracts due to heat and cold, it can adaptively deform to keep the gap between the solid seal 6 and the wall panel 1 / stratum 4 filled, block the infiltration of water, and ensure the sealing effect.
[0037] The seal 6 is wrapped around the outside of the sealing buffer zone 5, and has a first bonding surface 601 in direct contact with the wall panel 1, and also has a second bonding surface 602 in direct contact with the stratum 4; the two bonding surfaces ensure that the seal 6 is stable and does not shake, and at the same time, the bonding surfaces are tightly bonded to the wall panel 1 and the stratum 4. There is no gap in appearance after construction, which is convenient for cleaning and is also conducive to the subsequent construction of waterproof glue.
[0038] The waterproof adhesive layer 7 is coated on the outer exposed surface of the seal 6 (the exposed surface is temporary and will be covered after the waterproof adhesive layer 7 is constructed), and the edge of the waterproof adhesive layer 7 extends to the stratum 4 and the wallboard 1 on the same side; the waterproof adhesive layer 7 is a layer formed after the liquid waterproof plugging glue is painted. After construction, it reduces the penetration of water into the interior of the seal 6, and at the same time has a certain inhibitory effect on the shrinkage and expansion deformation of the concrete seal.
[0039] In the actual construction process, the gap between the interface of the wall panel 1 and the floor groove 2, and the gap between the interface of the floor groove 2 and the stratum 4 are filled with a sealant layer 8; the sealant is used to seal the gaps between the wall panel 1, the floor groove 2 and the stratum 4 caused by assembly.
[0040] In this embodiment:
[0041] See also Figure 3 The seal 6 can be a concrete slope. The concrete used in the construction process is generally C25 concrete, and its cross section is triangular, so that it has a slope for dispersing water.
[0042] See also Figure 4 The sealing buffer tape 5 is a continuous strip, and its cross section is L-shaped after adhesion; the sealing buffer tape 5 is SBS asphalt coil, butyl tape or waterproof adhesive layer. Through the comparison of construction and experimental data, the actual sealing effect of butyl tape is the best, especially the butyl tape with a thickness of 3mm and a width of 100mm.
[0043] The butyl tape used can be a single-sided butyl tape. During the construction process, the adhesive surface of the single-sided butyl tape is bonded to the stratum 4, the trench 2 and the wall panel 1, and the construction is easier with the single-sided butyl tape.
[0044] The butyl tape implemented can also be a double-sided butyl tape. During the construction process, one bonding surface of the double-sided butyl tape is bonded to the stratum 4, the trench 2 and the wall panel 1, and the other bonding surface is bonded to the subsequently formed solid seal 6, so that the combination is more stable.
[0045] In this embodiment: In order to further increase the stability of concrete sealing and reduce the slippage of concrete sealing during expansion and contraction, connecting rivets 9 and connecting bolts 10 are added. The connecting rivets 9 and connecting bolts 10 are distributed equidistantly or unequally along the length direction of the sealing buffer zone 5 (the direction of the connecting seam of the wall corner). The connecting rivets 9 and connecting bolts 10 can be used separately or in combination.
[0046] During the specific construction process: one end of the connecting rivet 9 is passed through the connecting wall panel 1, the ground groove 2 and the sealing buffer belt 5, and the other end is extended outward and buried in the solid seal 6, connecting the wall panel 1, the ground groove 2 and the solid seal 6, so as to play a restraining and stabilizing effect; during construction, the connecting rivet 9 is first provided, and then the solid seal is cast, and the solid seal is combined with the rivet after cooling and forming.
[0047] During the specific construction process, one end of the connecting bolt 10 is fixed in the stratum 4, and the other end passes through the second joint surface 602 and is buried in the solid seal 6, thereby connecting the solid seal 6 and the stratum 4 to constrain them from another direction; during construction, the connecting bolts and the sealing buffer belt 5 are first installed on the stratum 4, and finally the solid seal is poured. After the solid seal is cooled and formed, it is tightly combined with the connecting bolts.
[0048] The parts not described in detail in this embodiment are prior art.
[0049] It should be noted that although the utility model is described through the above embodiments, the utility model can also have other multiple embodiments. Without departing from the spirit and scope of the utility model, it is obvious that those skilled in the art can make various corresponding changes and deformations to the utility model, but these changes and deformations should all fall within the scope of protection of the attached claims of the utility model and their equivalents.
