Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a heat-insulating integral non-removable formwork anchoring structure. Background Art

[0002] In conventional concrete pouring construction, formwork is set up to form a pouring boundary surface. After pouring and forming, the formwork is removed, and then the pouring structure is obtained, and the construction treatment of the surface heat-insulating layer is continued. This traditional structure has complex construction procedures, consumes energy in removing the formwork, and is prone to damage the surface of the pouring structure during the removal process, which has an adverse impact on the subsequent construction of the heat-insulating layer. Therefore, an integrated heat-insulating non-removable formwork has been proposed. After construction pouring, the non-removable formwork is the heat-insulating layer on the surface of the pouring structure, and there is no need to remove the formwork and re-construct the heat-insulating layer. Currently, the traditional construction process adopted for the non-removable formwork heat-insulating integrated board is that after the non-removable formwork heat-insulating integrated board is processed, mortise and tenon holes are drilled with a drill bit. The aperture of the holes is generally 45 to 50 mm, and the depth is 50 mm. During the concrete pouring process, the concrete enters the mortise and tenon holes and solidifies, so as to realize the combined forming of the formwork and the pouring structure. This traditional method has the problem of a relatively small contact area with the concrete, and it is difficult to ensure the firm bonding between the formwork heat-insulating integrated board and the concrete, and the formwork is prone to falling off after forming.

[0003] It can be seen that there is still room for urgent improvement in the current anchoring scheme of the non-removable formwork heat-insulating integrated board, and it should be optimized to improve its stability and reliability after pouring. Therefore, a more reasonable technical solution needs to be proposed to solve the technical problems existing in the prior art. Summary of the Utility Model

[0004] To at least overcome one of the above-mentioned defects, the utility model proposes a heat-insulating integral non-removable formwork anchoring structure. By improving the structure of the heat-insulating integral non-removable formwork, a structure for preventing detachment and reverse is formed during the process of concrete pouring, thereby ensuring the stable and reliable connection and cooperation between the heat-insulating integral non-removable formwork and the pouring structure after the concrete pouring is completed.

[0005] To achieve the above purpose, the anchoring structure disclosed by the utility model can adopt the following technical solutions:

[0006] A heat-insulating integral non-removable formwork anchoring structure includes a pouring formwork body. A plurality of anti-retreat port structures are formed inside the pouring formwork body. The anti-retreat port structure includes a forming cavity. The inlet of the forming cavity is located on the concrete pouring side, and the inner cavity diameter of the forming cavity is larger than the diameter of the inlet. A heat-insulating structure is formed outside the pouring formwork body.

[0007] The above-mentioned disclosed anchoring structure uses the casting formwork body as the forming limiting surface of the concrete. When the concrete flows into the anti-retreat port structure and solidifies, the concrete fills the forming cavity and solidifies to form the anti-retreat structure. Therefore, it can keep the casting formwork body and the casting structure in close fit.

[0008] Furthermore, the structure of the forming cavity can be constructed in various forms and is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: the forming cavity includes tapered holes that extend from the inner side to the outer side of the casting formwork body, and the tapered holes are arranged at intervals on the casting formwork. When the above scheme is adopted, the tapered holes can be circular holes or polygonal holes, and can be through holes or blind holes.

[0009] Furthermore, in order to improve the integrity of the casting formwork body and the casting structure, the structure of the forming cavity is optimized to improve the tightness of the combination. There are various schemes that can be adopted and it is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: when the tapered hole penetrates the casting formwork body, several attachment recessed structures are formed on the hole wall of the tapered hole. When the above scheme is adopted, after forming a smooth tapered hole wall, the attachment recessed structures can be processed on the hole wall of the tapered hole from the outer side of the casting formwork body.

[0010] Furthermore, the attachment recessed structures can be in various forms and are not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: the attachment recessed structures include grooves or concave holes. When the above scheme is adopted, the grooves can be constructed as strip grooves or annular grooves, and the concave holes can be distributed at intervals along the hole wall.

[0011] Still further, in some other schemes, the forming cavity can be constructed in other schemes. Here, an optimization is carried out and one feasible option is proposed: the forming cavity includes a tapered groove, the notch of the tapered groove is located on the inner side of the casting formwork body, and the bottom of the tapered groove extends to the outer side of the casting formwork body. When the above scheme is adopted, the tapered groove does not penetrate the casting formwork body.

[0012] Still further, the trend of the tapered groove can adopt various schemes. For example, in some schemes, it can be set as an arc, and in some schemes, it can be set as a circle. It is not uniquely limited. Here, an optimization is carried out and one feasible option is proposed: the tapered groove is in a long strip shape and is arranged at intervals on the casting formwork body. When the above scheme is adopted, the tapered groove is horizontally arranged, which can achieve the purpose of anti-disengagement and anti-falling after the casting structure solidifies.

[0013] Further, in order to improve the integrity between the casting formwork body and the casting structure, the structure of the conical groove wall can be optimized. The specific optimization method is not uniquely limited. Here, one feasible option for optimization is proposed: several attachment depressions are formed on the wall of the conical groove. When the above solution is adopted, the wall of the conical groove can better maintain an integral connection with the cast structure, thereby maintaining the stability of the casting formwork.

[0014] Furthermore, the attachment depression structures provided on the groove wall can be configured in various forms, which is not uniquely limited. Here, one feasible option for optimization is proposed: the attachment depression structure includes grooves or concave holes. When the above solution is adopted, the grooves can be arranged along the extension direction of the groove, and the concave holes can be arranged at uniform intervals.

[0015] Further, the joint between the casting formworks will affect the casting effect. In order to improve the flatness of the casting surface, the joint of the casting formworks is optimized. Here, one feasible option is proposed: a splicing structure is formed between adjacent casting formwork bodies. When such a solution is adopted, the splicing structure includes a clamping structure.

[0016] The above content discloses the anchoring structure formed by the thermal insulation integral non-removable formwork. The present invention also discloses an anchoring method, which will be described below.

[0017] A thermal insulation integral non-removable formwork anchoring method includes:

[0018] Erect a formwork scaffold, connect the formwork to the formwork scaffold correspondingly and fix it, connect the outer side of the formwork to the formwork scaffold, and leave the inner side of the formwork for subsequent concrete casting and forming;

[0019] Splice adjacent formworks, keep the transition surface between adjacent formworks flat and form a casting limit surface, and at the same time set two casting limit surfaces to form a casting space relatively;

[0020] Inject concrete into the casting space and wait for the concrete to solidify and form;

[0021] Remove the formwork scaffold to make the formwork become the thermal insulation outer layer of the casting structure.

[0022] Compared with the prior art, some beneficial effects of the disclosed technical solution of the present invention include:

[0023] In the thermal insulation integral non-removable formwork of the present invention, the formed casting structure can fit the formwork and maintain an integral body. After casting, it forms the outer thermal insulation layer of the casting structure, eliminating the process of removing the formwork, simplifying the construction process, and at the same time being able to maintain stable and reliable connection.

[0035] As Figure 1 shown, this embodiment provides a heat-insulating integral non-removable formwork anchoring structure, which includes a casting formwork body 1. A plurality of anti-retreat structures 2 are formed on the inner side of the casting formwork body 1. The anti-retreat structure 2 includes a forming cavity. The inlet of the forming cavity is located on the concrete casting side, and the internal cavity diameter of the forming cavity is larger than the diameter of the inlet; a heat-insulating structure 4 is formed on the outer side of the casting formwork body 1.

[0037] For the above-mentioned disclosed anchoring structure, the casting formwork body 1 is used as the forming limiting surface of the concrete. When the concrete flows into the anti-retreat port structure 2 and solidifies, the concrete fills the forming cavity and solidifies to form the anti-retreat structure. Therefore, the casting formwork body 1 can be kept in close contact with the casting structure 5.

[0043] The splicing seam between the casting formworks will affect the casting forming effect. In order to improve the flatness of the casting surface, the splicing part of the casting formworks is optimized. In this embodiment, one feasible option is adopted: a splicing structure is formed between adjacent casting formwork bodies 1. When such a solution is adopted, the splicing structure includes a clamping structure.

[0044] Embodiment 2

[0048] As Figure 3 shown, the trend of the tapered groove 202 can adopt various schemes. For example, in some schemes, it can be set as an arc, and in some schemes, it can be set as a circle. It is not uniquely limited. In this embodiment, optimization is carried out and one of the feasible options is adopted: the tapered groove 202 is strip-shaped and is arranged at intervals on the casting formwork body 1. When the above scheme is adopted, the tapered groove 202 is horizontally arranged, which can achieve the purpose of anti-disengagement and anti-falling after the casting structure 5 solidifies and forms.

[0049] In order to improve the integrity between the casting formwork body 1 and the casting structure 5, the structure of the wall of the tapered groove 202 can be optimized.
