Description

Technical Field

[0001] The utility model relates to the technical field of concrete material curing, in particular to an aerogel curing template. Background Art

[0002] Due to the extremely harsh climatic and environmental conditions in the plateau area, which are characterized by high altitude, large temperature differences, frequent negative temperatures, strong radiation, severe cold and drought, and high wind speeds, and due to the complex geological terrain and frequent mountain disasters in the plateau area, transportation infrastructure such as railways and highways often have dense mountain tunnels and bridges. Compared with tunnels, bridge structures in an open-air state are more easily affected by the climate environment, especially reinforced concrete bridges. The harsh service environment will have an adverse effect on the concrete pouring, maintenance, service and other stages.

[0003] During the construction, pouring, and curing phases, the heat released by cement hydration causes a high hydration temperature rise in large structures such as piers and abutments. Large temperature differences between the interior and exterior of the concrete can also create additional tensile stresses due to large temperature differences. When these additional tensile stresses exceed the concrete's tensile strength, they can lead to cracking. Furthermore, factors such as high plateau winds and low humidity can cause early drying shrinkage in the concrete, further exacerbating the risk of early cracking.

[0004] During the subsequent operation and maintenance phase of the bridge, concrete will experience durability issues such as freeze-thaw damage when it is exposed to alternating dry and wet conditions and positive and negative temperatures. This is especially true when coupled with early shrinkage cracks in the concrete and physical wind erosion from strong winds. The durability issues faced by bridge pier concrete are even more serious. Therefore, this proposal proposes an aerogel curing formwork to address the above issues. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] The utility model provides Figure 1-3 An aerogel curing formwork shown includes cement concrete 1 and further includes:

[0028] An aerogel functional layer is provided on the outer wall of the cement concrete 1. The aerogel functional layer is used to insulate the outer wall of the cement concrete 1. An embedded part 6 is provided between the connection between the aerogel functional layer and the cement concrete 1. The embedded part 6 is used to fix the aerogel functional layer and the cement concrete 1.

[0029] Specifically, the aerogel functional layer includes an aerogel felt 2, which is arranged on the outer wall of the cement concrete 1, and one end of the embedded part 6 is inserted and connected to the middle of the aerogel felt 2;

[0030] The aerogel functional layer further includes a first curing membrane 4 and a second curing membrane 5 . The first curing membrane 4 is arranged between the aerogel felt 2 and the cement concrete 1 . The other end of the embedded part 6 is inserted and connected to the middle of the cement concrete 1 .

[0031] It should be noted that aerosol felt 2 is a new type of thermal insulation material, mainly composed of gas and solid components, with good thermal insulation performance. It is usually composed of tiny bubbles or gaps, making it difficult for heat to conduct, thereby effectively reducing heat loss.

[0032] Some embedded parts 6 are first made on the surface and inside of the aerogel felt 2 for later reinforcement and adhesion to the cement concrete 1 matrix. The first curing film 4 and the second curing film 5 are respectively attached to the two sides of the aerogel felt 2. The first curing film 4 and the second curing film 5, the embedded parts 6 and the aerogel felt 2 form an integral material, which is called an aerogel functional layer.

[0033] Furthermore, the embedded part 6 includes:

[0034] Embedded plate 601, embedded plate 601 is connected to the middle part of the aerosol felt 2;

[0035] Embedded hooks 602, multiple embedded hooks 602 are respectively fixedly connected to the corners of the embedded plate 601, and the ends of the multiple embedded hooks 602 away from the embedded plate 601 all penetrate the first curing film 4 and are inserted and connected to the middle part of the cement concrete 1. The end of the embedded hook 602 inserted into the cement concrete 1 is set to a curved hook shape, and the curved hook shape is used to increase the insertion area of ​​the embedded hook 602 and the cement concrete 1.

[0036] It should be noted that, through the combined design of the hook-shaped embedded hook 602 and the embedded plate 601, the embedded part 6 can be more firmly connected and installed between the aerosol felt 2 and the cement concrete 1, making the connection and anchoring between the two more stable.

[0037] The formwork body 3 is arranged on the side of the aerogel functional layer away from the cement concrete 1. The formwork body 3 is used to attach the aerogel functional layer to the outer wall of the cement concrete 1. The second curing membrane 5 is arranged between the aerogel felt 2 and the formwork body 3.

[0038] Specifically, a fixing piece is provided between the aerosol felt 2 and the template body 3 , and the fixing piece is used for detachable connection between the aerosol felt 2 and the template body 3 .

[0039] It should be noted that the entire aerogel functional layer is fixed to the formwork body 3. The use of fixings can facilitate the fixing of the aerogel felt 2 to the formwork body 3. At the same time, it also ensures that when the concrete is demolded, the aerogel functional layer is separated from the formwork body 3, but the aerogel functional layer and the cement concrete 1 matrix cannot be separated. In this way, the formwork material formed by the combination of the formwork body 3 and the aerogel functional layer is an aerogel curing formwork. In the aerogel curing formwork, the aerogel functional layer is fixed to the side of the formwork body 3 that contacts the cement concrete 1. The side of the aerogel functional layer with the embedded parts 6 faces the cement surface, and the other side is fixed to the formwork body 3 by fixings. The size of the aerogel functional layer is the same as that of the formwork body 3, and the size of the aerogel functional layer adopts a positive tolerance.

[0040] Fixing parts include:

[0041] The inserting cone 7 is inserted and connected to the side of the aerosol felt 2 close to the second curing film 5, and the inserting cone 7 passes through the second curing film 5. A threaded groove is opened in the middle of the inserting cone 7;

[0042] The connecting bolt 8 has a threaded end which is inserted and connected with the middle portion of the template body 3 , and a threaded end which is inserted and connected with the inner wall of the thread groove.

[0043] It should be noted that the connecting bolt 8 can be disassembled by interpenetrating the threads between the connecting bolt 8 and the interpenetrating cone 7, thereby enabling the template body 3 to be disassembled.

[0044] Example 1, as Figure 4 As shown, when in use, the aerogel curing template is assembled to form the shape of the bridge pier, the aerogel functional layer contacts the cement concrete 1 castable inwardly, and one end of the embedded part 6 on the surface of the aerogel functional layer is embedded in the cement concrete 1 and solidified together with the cement concrete 1 to fix the aerogel functional layer, as shown in FIG. Figure 1 As shown, after the cement formwork body 3 needs to be demolded, the formwork body 3 is separated from the aerogel functional layer, and the aerogel functional layer is fixed on the cement bridge pier. Finally, glass aluminum foil cloth is used for sealing and covering to form the final exterior finish, and connecting bolts 8 are used to be threadedly connected with the interpenetrating cone 7 to ensure that the glass aluminum foil cloth is connected to the surface of the aerogel functional layer, thereby meeting the requirements of integrated early maintenance and back-end operation and maintenance.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
