Abstract
Description
Technical Field
[0001] The utility model relates to the field of prefabricated buildings, and more specifically, to a prefabricated building sealing and waterproofing device. Background Technique
[0002] A prefabricated building refers to a building in which a large amount of on-site operation work in the traditional construction method is transferred to a factory. Building components and fittings are processed and manufactured in the factory and transported to the building construction site, and are assembled and installed on-site through reliable connection methods. Prefabricated buildings mainly include precast prefabricated concrete structures, steel structures, modern timber structures, etc.
[0003] During the process of prefabricated building, when pouring the wall, it is necessary to use a pouring formwork for erection. The mutual pouring formworks are fixed by binding steel bars at the joint positions, and then concrete is poured. At the same time, after pouring the concrete, it is necessary to use the formwork to shield and protect the concrete. However, the mutual lap sealing performance of the traditional pouring formwork is poor during the erection process, and the sealing effect with the concrete is also poor. As a result, during the pouring process, not only is it easy to cause slurry leakage, but also external water sources are easy to enter the concrete through the gaps, thereby affecting the strength of the concrete.
[0004] Therefore, the utility model proposes a prefabricated building sealing and waterproofing device. Content of the Utility Model

[0022] Next, the attached drawings in the embodiments of the present utility model will be combinedFigures 1-4 , clearly and completely describe the technical solutions in the embodiments of the present utility model.
[0023] Please refer to Figures 1-4 , in the embodiments of the present utility model, an assembled building sealing and waterproofing device includes a main body 1. One end of the main body 1 is fixedly connected with a connecting side plate 3, and the other end is movably provided with a sealing plate 4. A sealing layer 2 is fixedly connected between the main body 1 and the connecting side plate 3. An inner support plate 8 is fixedly connected inside the main body 1. An adjusting component 5 is movably embedded inside the main body 1. The adjusting component 5 is simultaneously connected to the sealing plate 4. The adjusting component 5 includes an adjusting screw rod 6, a connecting rod 7 and a connecting head 9 which are fixedly connected. An elastic strip 10 and an auxiliary spring 11 which are provided in a matching manner are fixedly connected to the inner surface of the sealing plate 4. The elastic strip 10 and the auxiliary spring 11 are both located inside the main body 1.
[0024] In the embodiments of the present utility model, the main body 1 is arranged in a rectangular hollow shape. The connecting side plate 3 and the main body 1 are fixedly connected in a "T" shape. The sealing layer 2 is longitudinally arranged along the docking positions at both ends of the main body 1 and the connecting side plate 3, and is set as a foamed plastic layer. Through the main body 1, the effect of supporting between two external casting templates is achieved. Through the connecting side plate 3, the effect of connecting and fixing with the external template is achieved. Through the sealing layer 2, the effect of ensuring the sealing and buffering between the external template and this device is achieved.
[0025] When installing multiple groups of external casting templates, place the whole device between two templates. The main body 1 supports the casting templates, and the connecting side plate 3 fits the outer surface of the external template. The user can connect and fix it to the template with external screws.
[0026] The adjusting screw rod 6 is in threaded connection with the main body 1. The connecting rod 7 is fixedly connected to the middle position inside the sealing plate 4 through the connecting head 9. The sealing plate 4 is arranged as a trapezoidal bent plate and is set as an elastic rubber plate. The adjusting screw rod 6 and the connecting rod 7 simultaneously penetrate through the inner support plate 8. Through the adjusting screw rod 6 and the connecting rod 7, the effect of adjusting the distance between the sealing plate 4 and the main body 1 is achieved. Through the sealing plate 4, the effect of fitting the surface of the external casting template to achieve sealing is achieved. Through the inner support plate 8, the effect of supporting the main body 1 from the inside and ensuring the adjustment stability of the adjusting screw rod 6 and the connecting rod 7 is achieved.
[0027] There are two sets of the elastic strip 10 and the auxiliary spring 11 which are set in a supporting manner. They are located on both inner sides of the sealing plate 4 and are distributed on both sides inside the main body 1 at the same time. The elastic strip 10 is set as an "L"-shaped bent elastic metal strip. The auxiliary spring 11 is fixedly connected to the inner bent position of the elastic strip 10 and is arranged in a triangular shape as a whole with the elastic strip 10. One end of the elastic strip 10 is fixedly connected to the inside of the main body 1 at the same time. The elastic strip 10 and the auxiliary spring 11 provide elasticity for the sealing plate 4 to achieve the effect of assisting the sealing plate 4 to fit the external template to realize sealing.
[0028] When using this device, place this device between two sets of pouring templates. First, fix the connecting side plate 3 to the surface of one side of the external template through external screws. Then, according to the distance between the surface of the other side of the external template and the sealing plate 4, the user rotates the adjusting assembly 5 to drive the sealing plate 4 to adjust the distance between it and the surface of the external template until the sealing plate 4 fits the surface of the external template. At this time, the sealing plate 4 realizes the sealing treatment between the external templates from the inner side position. During the adjustment of the sealing plate 4, the elastic strip 10 and the auxiliary spring 11 are compressed and stretched adaptively along with the adjustment of the sealing plate 4 to provide elasticity for the sealing plate 4, which is beneficial to the contact sealing between the sealing plate 4 and the surface of the external template.
