[0031] The conventional practice for existing concrete exterior wall formwork leaves a 2cm gap (to eliminate errors in the formwork production and leveling process). This gap is often sealed with mortar cementitious material, but the sealing strength is insufficient to resist the pressure during concrete pouring, often leading to grout leakage or even aggregate segregation during pouring, resulting in loose concrete and internal voids.
[0032] This invention provides a sealing structure and a mold shell assembly, aiming to provide a high-strength structure that can fill the gaps in the mold shell splicing, thereby reducing the problem of slurry leakage in the later stage.
[0033] Please see Figs. 1 to 3 In one embodiment of this utility model, the sealing structure 100 is used to be installed on a mold shell to fill the gaps in the joints of the mold shells. The sealing structure 100 includes an elastic body 1 and a fixing part 2. The elastic body 1 has a first side 11 and a second side 12 facing each other. The first side 11 is used for contact with the mold shell, and the second side 12 is used for contact with another mold shell or a mounting wall. The fixing part 2 has a first end 21 and a second end 22 facing each other. The first end 21 of the fixing part 2 is disposed on the elastic body 1 and is located between the first side 11 and the second side 12 of the elastic body 1. The second end 22 is used to connect to the mold shell so that the elastic body 1 is fixed on the mold shell.
[0034] The technical solution of this utility model adopts the setting method of the elastic body 1, which is installed at the gap of the mold shell splicing. Utilizing the flexibility and compressibility of the elastic body 1, it can adapt to the changes in the gap of the mold shell splicing, which has strong adaptability, resulting in good gap filling effect, improving sealing performance, and reducing the problems of grout leakage and material leakage. The setting of the fixing part 2 not only ensures the firm connection between the fixing part 2 and the elastic body 1, but also allows the sealing structure 100 to be stably installed on the mold shell, thereby improving reliability.
[0035] It should be noted that the elastomer 1 may be made of EPDM (ethylene propylene diene monomer) rubber, which has good adhesion to putty and reduces problems such as peeling and cracking of the decorative layer.
[0036] In this embodiment, the form of the elastomer 1 is not specifically limited; for example, it can be strip-shaped or cylindrical. Preferably, in this embodiment, it is set to a square strip shape, which is beneficial for adapting to the joints of the mold shell and reducing material leakage.
[0037] It is understood that the fixing part 2 can be provided by means of steel wire rope, iron wire, or strip plate, etc.
[0038] It is understood that the connection between the fixing part 2 and the mold shell can be achieved by bolting, snap-fitting, or bonding, etc., to connect the second end 22 of the fixing part 2 to the mold shell.
[0039] It should be noted that the mold shell contains wire mesh. Before pouring, the fixing part 2 can be fixed to the wire mesh, and then the fixing part 2 can be connected to the mold shell. Specifically, in this embodiment, preferably, the fixing part 2 is a steel wire rope, which is tied and fixed to the steel wire mesh inside the mold shell to achieve the purpose of connecting the fixing part 2 to the mold shell.
[0040] To enhance the strength of the elastomer 1, in one embodiment, the sealing structure 100 further includes a support portion 3 disposed within the elastomer 1.
[0041] This configuration, by placing the support part 3 inside the elastic body 1, provides a certain support for the elastic body 1, thereby improving the strength of the elastic body 1. This results in good flexibility during use, as well as high connection strength, thus improving the reliability of the mold shell splicing.
[0042] It is understood that the support part 3 can be provided as a rod, such as a steel wire or a steel column; or as a plate, such as a strip.
[0043] In one embodiment, the first end 21 of the fixing part 2 extends into the elastic body 1 and connects with the support part 3.
[0044] With this configuration, when the fixing part 2 is tightly connected to the elastic body 1 and the supporting part 3, they can jointly withstand external forces and distribute stress, thereby extending the service life of the sealing structure 100. At the same time, it helps to reduce unnecessary deformation or displacement of the sealing structure 100 under stress.
[0045] In one embodiment, the support portion 3 is arranged corresponding to the length direction of the elastic body 1.
[0046] This configuration provides stable support for the elastomer 1, which helps to reduce the twisting or lateral displacement of the elastomer 1 when subjected to force, thereby maintaining its original shape and function and improving the stability of the mold shell splicing.
[0047] In one embodiment, a plurality of fixing parts 2 are provided, and the plurality of fixing parts 2 are spaced apart along the length direction of the elastic body 1.
[0048] This configuration allows for more effective distribution and absorption of stress from external loads through the multiple fixing parts 2. This helps to ensure more uniform stress distribution on the elastomer 1, reducing excessive deformation or damage, and thus improving the structural strength and stability of the sealing structure 100.
[0049] In one embodiment, the first end 21 of the fixing part 2 is wound around the second end 22 to form an annular connecting part 23 with a through hole, and the supporting part 3 is connected to the fixing part 2 corresponding to the through hole of the annular connecting part 23.
[0050] This configuration simplifies the connection process by connecting the support part 3 through the through hole of the annular connecting part 23. At the same time, it increases the contact area at the connection between the support part 3 and the fixing part 2, thereby improving the connection strength and the reliability of the connection.
[0051] It should be explained that, in this embodiment, preferably, the fixing part 2 is a steel rope, which has a certain strength and is also relatively flexible in its installation method, and can be used by knotting.
[0052] This utility model also proposes a mold shell assembly 200, which includes a sealing structure 100. The specific structure of the sealing structure 100 is as described in the above embodiments. Since this mold shell assembly 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0053] In one embodiment, the mold assembly 200 includes a first mold 1a, which includes a steel reinforcement frame 11a and two mold plates 12a, which are respectively disposed on both sides of the steel reinforcement frame 11a; wherein, at least one of the mold plates 12a is provided with the sealing structure 100.
[0054] Thus, by providing a sealing structure 100 on at least one of the mold plates 12a, the joints between the molds or the places where the molds are connected to other components are effectively sealed, which helps to reduce the leakage of internal materials (such as concrete) and also prevents external impurities from entering, thus ensuring the quality of the pouring.
[0055] It should be explained that, in order to ensure the quality of the casting, preferably, in this embodiment, the sealing structure 100 is provided on both of the mold plates 12a to improve the sealing effect.
[0056] In one embodiment, multiple first mold shells 1a are provided, and a gap is formed between the mold shell plates 12a of two adjacent first mold shells 1a, and the sealing structure 100 fills the gap.
[0057] This configuration, by filling the gaps between the mold plates 12a with the sealing structure 100, effectively prevents internal materials (such as concrete) from leaking out of the gaps, while preventing external moisture or impurities from intruding, thus improving the airtightness during the pouring process and the quality of the final product.
[0058] In one embodiment, the elastic body 1 is disposed in the gap between the mold plate 12a of two adjacent first mold shells 1a, the first side 11 of the elastic body 1 contacts the mold plate 12a of one first mold shell 1a, the second side 12 of the elastic body 1 contacts the mold plate 12a of the other first mold shell 1a, and the second end 22 is connected to one of the steel reinforcement skeletons 11a of the two first mold shells 1a.
[0059] With this configuration, the elastic body 1, through its flexibility and compressibility, can adapt to the gap between the mold plate 12a of two adjacent first mold shells 1a and perform sealing treatment. Through the connection between the elastic body 1 and the steel reinforcement skeleton 11a, the installation firmness of the elastic body 1 is improved, thereby increasing the assembly strength.
[0060] Preferably, in this embodiment, the connection between the second end 22 and the steel reinforcement skeleton 11a of the two first mold shells 1a improves the connection strength.
[0061] In addition, this utility model also proposes a method of using the sealing structure 100 and the mold shell assembly 200, providing the following elastomer 1, the fixing part 2, the supporting part 3 and the first mold shell 1a;
[0062] By inserting the support part 3 into the interior of the elastic body 1, connecting the fixing part 2 to the mold plate 12a of the first mold shell 1a, pre-embedding the sealing structure 100 on one of the mold plates 12a of the first mold shell 1a, pouring concrete, and curing; referring to the above steps, pre-embedding the sealing structure 100 on the other mold plate 12a of the first mold shell 1a, forming a prefabricated mold shell product with a sealing structure.
[0063] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
