Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a single-side formwork structure for an outer wall of a basement. Background Art

[0002] During the construction of the basement exterior wall structure, if the distance between the slope outside the wall and the wall is insufficient or narrow, it will be extremely difficult to support the formwork on both sides during formwork construction. In this case, it is necessary to pour the backfill area between the proposed basement exterior wall and the slope at the same time, and only need to support the formwork on the indoor side of the shear wall.

[0003] Supporting a single-sided formwork is more difficult than supporting a double-sided formwork. In the prior art, a triangular support frame is often used to support the single-sided formwork. However, this support method often requires the manufacture of a triangular support frame with a complex structure, which requires the arrangement of a complex support structure, resulting in a cumbersome installation process and high cost. Therefore, a single-sided formwork structure for the exterior wall of a basement is required. Summary of the invention

[0004] In view of the above-mentioned deficiencies existing in the prior art, the utility model provides a single-sided formwork structure for the basement exterior wall, which is used to solve the problem that the existing support method requires the manufacture of a complex triangular support frame, the installation process is relatively cumbersome, and the cost is high.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A single-sided formwork structure for a basement exterior wall comprises a wooden formwork, wherein the wooden formwork is closely attached to the original groove of the exterior wall for casting a concrete body; a secondary keel, wherein the secondary keel is installed on the surface of the wooden formwork; a main keel, wherein the main keel is installed on the surface of the secondary keel, wherein the surface of the main keel is connected with a supporting diagonal rod; an internally threaded climbing cone, wherein the end of the internally threaded climbing cone is pre-embedded in the bottom plate concrete, wherein the internally threaded climbing cone is connected to the main keel via a supporting diagonal rod; and an anchoring screw is installed on the surface of the main keel, thereby having a simple structure and being easy to use, thereby ensuring the construction quality of the exterior wall of the basement under narrow slope conditions, saving the construction period of backfilling the exterior wall, and improving work efficiency.

[0007] Furthermore, the end of the anchoring screw penetrates the wooden formwork and extends into the interior of the exterior wall slope, thereby ensuring the stability of the formwork structure.

[0008] Furthermore, the internal thread climbing cone can adjust the connection length with the supporting diagonal rod, thereby freely adjusting the length and angle of the supporting diagonal rod to be suitable for different environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Among them, the drawings are only used for illustrative explanations, and they only represent schematic diagrams rather than actual pictures, and should not be understood as limitations on this patent; in order to better illustrate the embodiments of the utility model, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the size of the actual product; for those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0014] Example:

[0015] like Figure 1 As shown, the utility model is a single-sided formwork structure for the outer wall of a basement, comprising a wooden formwork 1, the wooden formwork 1 is close to the original groove of the outer wall for pouring a concrete body 2; a secondary keel 3, the secondary keel 3 is installed on the surface of the wooden formwork 1; a main keel 4, the main keel 4 is installed on the surface of the secondary keel 3, and the surface of the main keel 4 is connected with a supporting diagonal rod 5; an internal thread climbing cone 6, the end of the internal thread climbing cone 6 is pre-buried in the bottom plate concrete 7, and the internal thread climbing cone 6 is connected to the main keel 4 through the supporting diagonal rod 5; the surface of the main keel 4 is installed with an anchoring screw 8, thereby having a simple structure and being easy to use, thereby ensuring the construction quality of the outer wall of the basement under narrow slope conditions, saving the construction period of backfilling the outer wall, and improving work efficiency.

[0016] The end of the anchoring screw 8 passes through the wooden formwork 1 and extends into the interior of the external wall slope, thereby ensuring the stability of the formwork structure.

[0017] The internal thread climbing cone 6 can adjust the connection length with the supporting diagonal rod 5, thereby freely adjusting the length and angle of the supporting diagonal rod 5 to be suitable for different environments.
