Description

Technical Field

[0001] This utility model belongs to the field of bridge construction technology, and in particular relates to a casting and molding device for building construction in cold regions. Background Technology

[0002] Bridge piers are substructures that support the bridge span and transfer dead loads and vehicle live loads to the foundation; abutments are located on both sides of the bridge. Cylindrical piers are widely used, and the formwork casting method is standardized and repetitive, making the construction of cylindrical piers simpler.

[0003] When bridge piers are built in cold regions, the large temperature difference between the inside and outside of the concrete mortar after hot concrete mortar is injected into the formwork can affect the quality of the pier's formation. Therefore, cold-proofing treatment is required for the bridge piers. Utility Model Content

[0004] This utility model addresses the problem in the prior art where the casting quality of bridge piers is affected by significant internal and external temperature variations during casting in cold regions, and proposes the following technical solution:

[0005] A casting and molding device for building construction in cold regions includes: a pier formwork, wherein the pier formwork is composed of multiple independent splicing plates, and multiple insulation boards are provided on the inner side of the pier formwork, wherein the number of insulation boards is the same as the number of splicing plates, and the insulation boards are composed of a waterproof metal outer layer and an insulation inner layer;

[0006] The bottom and one side of the insulation board protrude from the bottom of the splicing board, and the top and the other side of the insulation board have a certain gap with the top of the splicing board.

[0007] As a preferred embodiment of the above technical solution, a limiting piece is movably inserted into the outer side of the insulation board, and the limiting piece is fixedly connected to the splicing plate.

[0008] As a preferred embodiment of the above technical solution, a plurality of fixing components are provided between the insulation board and the corresponding splicing board. The fixing components include fixing plates, which are movably inserted into the limiting plates. One end of the fixing plate is rotatably inserted with a bolt, and one end of the bolt is rotatably inserted into the splicing board. The bolt and the splicing board are threaded together.

[0009] As a preferred embodiment of the above technical solution, the surface of the fixing plate is provided with an anti-slip layer, and the surface of the anti-slip layer is roughened.

[0010] As a preferred embodiment of the above technical solution, the two sides of the limiting piece are flush with the two sides of the splicing plate, and the limiting piece and the splicing plate are integrally formed.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. The insulation boards form an insulation "box" that can insulate the concrete mortar to prevent the temperature from dissipating too quickly, thereby reducing the temperature difference between the inside and outside of the concrete mortar and ensuring the molding quality of the concrete pier. In addition, the splicing joints of the insulation boards are not in the same position as the splicing joints of the pier formwork, which can reduce the heat loss from the gaps and further increase the insulation effect on the pier.

[0013] 2. Push the insulation board to move it on the limiting plate. The two sides of the insulation board can then be flush with the splicing plate. The splicing plate can provide a certain degree of protection for the insulation board, preventing the sides of the insulation board from being squeezed out of position and damaged when the pier formwork is removed for handling or storage.

[0019] To make the objectives, technical solutions, and advantages of the present utility model embodiments clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings. Example

[0020] Figures 1-2 In the middle, a casting and molding device for building construction in cold regions includes: a pier formwork 10, which is composed of multiple independent splicing plates 11 spliced ​​together, and multiple insulation boards 20 are provided on the inner side of the pier formwork 10. The number of insulation boards 20 is the same as the number of splicing plates 11. The insulation board 20 is composed of a waterproof metal outer layer 21 and an insulation inner layer 22.

[0021] The bottom and one side of the insulation board 20 protrude from the bottom of the splicing plate 11, and the top and the other side of the insulation board 20 have a certain gap with the top of the splicing plate 11.

[0022] When pouring concrete for the bridge piers, multiple independent splicing plates 11 are first spliced ​​together to form a complete circular bridge pier template 10. Then, multiple bridge pier templates 10 are stacked in sequence. Because the bottom and one side of the insulation board 20 protrude from the bottom of the splicing plate 11, and there is a certain gap between the top of the insulation board 20 and the top of the splicing plate 11, the splicing point of the insulation board 20 and the splicing point of the bridge pier template 10 are not in the same position. The inner insulation layer 22 of the insulation board 20 insulates the concrete inside.

[0023] The insulation board 20 forms an insulation "box" that can insulate the concrete mortar to prevent excessive heat loss, thereby reducing the temperature difference between the inside and outside of the concrete mortar and ensuring the molding quality of the concrete pier. Furthermore, the splicing joints of the insulation board 20 and the pier formwork 10 are not in the same position, which can reduce heat loss from the gaps and further increase the insulation effect on the pier.

[0024] Figures 2-4 In the middle, the insulation board 20 is movably inserted into the outer side of the limiting piece 30, and the limiting piece 30 is fixedly connected to the splicing plate 11.

[0025] Before removing the pier formwork 10 for transport or storage, push the insulation board 20 to move it on the limiting plate 30. The two sides of the insulation board 20 can then be flush with the splicing plate 11. The splicing plate 11 can provide some protection for the insulation board 20, preventing the sides of the insulation board 20 from being squeezed out of position and damaged by external force.

[0026] Figures 2-3 In this process, multiple fixing components 40 are provided between the insulation board 20 and the corresponding splicing board 11. Each fixing component 40 includes a fixing piece 41, which is movably inserted into the limiting piece 30. One end of the fixing piece 41 is rotatably inserted with a bolt 42, and one end of the bolt 42 is rotatably inserted into the splicing board 11. The bolt 42 and the splicing board 11 are threaded together.

[0027] Rotating the bolt 42 causes the fixing plate 41 to move, and the fixing plate 41 contacts or leaves the surface of the insulation board 20, thereby completing the fixing or release of the insulation board 20, which facilitates the adjustment and fixing of the position of the insulation board 20.

[0028] Figures 2-3 In this process, the surface of the fixing piece 41 is provided with an anti-slip layer, and the surface of the anti-slip layer is roughened.

[0029] The anti-slip layer on the surface of the fixing plate 41 can increase the friction between it and the insulation board 20, making the static friction fixing of the insulation board 20 more secure.

[0030] Figure 4In the middle, the two sides of the limiting piece 30 are flush with the two sides of the splicing plate 11, and the limiting piece 30 and the splicing plate 11 are integrally formed.

[0031] The limiting piece 30 is flush with the two sides of the splicing plate 11, which can prevent the limiting piece 30 from protruding from the splicing plate 11 and not affect the assembly of the pier formwork 10.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
