Description

Technical Field

[0001] This utility model relates to the field of building construction, specifically to the technical field of thin wall construction in confined spaces. Background Technology

[0002] The construction process of concrete walls generally uses fair-faced concrete formwork. Specifically, after the fair-faced concrete formwork is erected and fixed, concrete is poured in the middle, and the formwork is removed after it solidifies.

[0003] However, in actual construction, it is often necessary to construct thin walls to form confined spaces, such as creating narrow ventilation shafts or structural cavities. When it is necessary to form thin walls in confined spaces, if the construction is carried out in two separate steps, the close proximity of the two thin walls can cause problems such as being unable to construct them or encountering difficulties in the process. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problems in the prior art, thereby providing a technology for constructing thin walls in a confined space.

[0005] To achieve the above objectives, this utility model provides a construction device for thin-walled wall structures in confined spaces, including fair-faced formwork, keel, square steel, polystyrene board and fixing screws;

[0006] The two sets of clear water templates are arranged in parallel relative to each other;

[0007] The keel is arranged on the outside of the fair-faced concrete template;

[0008] Square steel bars are arranged on the outside of the keel, and the square steel bars are arranged perpendicular to the keel.

[0009] Polystyrene boards are arranged between the two sets of clear water formwork, and the space between the polystyrene boards and the clear water formwork is used for wall casting.

[0010] The fixing screw passes through the two sets of clear water templates and the polystyrene board, and the two ends of the fixing screw are fixed to the square steel by nuts.

[0011] Preferably, the polystyrene board is constructed based on BIM.

[0012] Preferably, the fixing screw has a polystyrene board protective pad and a conical nut, the two sides of the polystyrene board protective pad abut against the polystyrene board and the steel mesh respectively, and the outer end face of the conical nut abuts against the clear water template.

[0013] Preferably, the polystyrene board protective pad has a U-shaped steel bar slot, which cooperates with the horizontal steel bars of the steel mesh frame.

[0014] Preferably, it also includes side templates, which are fixed at both ends of the two sets of clear water templates to form a four-sided annular continuous thin wall structure.

[0015] Preferably, the steel reinforcement mesh includes a main steel reinforcement mesh and a side steel reinforcement mesh, the main steel reinforcement mesh being located between the polystyrene board and the clear water formwork, and the side steel reinforcement mesh being located between the polystyrene board and the side formwork.

[0016] Preferably, a polystyrene protective pad is provided between the polystyrene board and the side template.

[0017] Preferably, multiple sets of polystyrene boards are stacked and combined together for use.

[0018] Preferably, it further includes a reinforcing bar spacer, the reinforcing bar spacer having a main body and a clip structure, the clip structure being fixed to the reinforcing bar.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By setting polystyrene boards between two parallel fair-faced formwork panels, two thin walls can be quickly formed without the need for sets of formwork and casting.

[0039] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0040] Example 1:

[0041] like Figure 1 , 2 As shown, this utility model provides a construction device for thin-walled wall structures in confined spaces, including a fair-faced formwork 10, a keel 20, a square steel 30, a polystyrene board 40, and a fixing screw 50;

[0042] The two sets of clear water templates 10 are arranged in parallel relative to each other;

[0043] The keel 20 is arranged on the outside of the clear water formwork 10;

[0044] Square steel 30 is arranged on the outside of the keel 20, and the square steel 30 is arranged perpendicular to the keel 20;

[0045] Polystyrene board 40 is arranged between the two sets of clear water formwork 10, and the space between the polystyrene board 40 and the clear water formwork 10 is used for wall casting.

[0046] The fixing screw 50 passes through the two sets of the clear water template 10 and the polystyrene board 40, and the two ends of the fixing screw 50 are fixed to the square steel 30 by nuts 51.

[0047] By placing polystyrene board 40 between two parallel fair-faced formwork 10, two thin walls can be quickly formed without the need for set-up formwork and casting. This results in two sets of thin walls in a narrow space and avoids the problem of difficulty in forming another set of thin walls due to the narrow space after forming one set of thin walls.

[0048] Preferably, the polystyrene board 40 is constructed based on BIM. BIM, or Building Information Modeling, is a tool for architecture, engineering, and civil engineering. This modeling method is more accurate and has fewer errors; this is existing technology and will not be elaborated further here. Alternatively, other existing methods can be used to process and form the required polystyrene board 40. Furthermore, polystyrene boards 40 with irregular structures can be provided as needed, thereby forming non-linear irregular structure walls.

[0049] Preferably, such as Figure 3 , 4 As shown in Figure 5, the fixing screw 50 has a polystyrene board protective pad 52 and a conical nut 54. The two sides of the polystyrene board protective pad 52 abut against the polystyrene board 40 and the steel mesh frame 60, respectively, and the outer end face of the conical nut 54 abuts against the clear water formwork 10. The polystyrene board protective pad 52 separates the steel mesh frame 60 from the polystyrene board 40 and plays a good supporting and fixing role, preventing the steel mesh frame 60 from moving accidentally during the pouring process.

[0050] The tapered nut 54 can be accurately positioned and then abutted against the clear water template 10, thus making the clear water template 10 and the screw form a stable relationship and preventing the clear water template 10 from tilting.

[0051] Preferably, the polystyrene board protective pad 52 has a U-shaped steel bar slot 53, which cooperates with the horizontal steel bars of the steel mesh frame 60. This structure makes the fixed support more stable.

[0052] Example 2:

[0053] Preferably, such as Figure 6 As shown, it also includes side templates 80, which are fixed at both ends of the two sets of clear water templates 10 to form a four-sided annular continuous thin wall structure.

[0054] Preferably, such as Figure 6 , 8 As shown in Figure 9, the steel reinforcement mesh 60 includes a main steel reinforcement mesh 61 and a side steel reinforcement mesh 62. The main steel reinforcement mesh 61 is located between the polystyrene board 40 and the clear water formwork 10, and the side steel reinforcement mesh 62 is located between the polystyrene board 40 and the side formwork 80.

[0055] Preferably, a polystyrene board protective pad 52 is provided between the polystyrene board 40 and the side template 80.

[0056] Preferably, multiple sets of polystyrene boards 40 are stacked together for use. In production, polystyrene boards 40 are generally formed to a specific thickness, but multiple polystyrene boards 40 can be stacked to form different thicknesses. This allows for quick adjustment of the number of polystyrene boards 40 as needed for the required wall thickness. This method is convenient for construction of walls of different types and sizes, making it more convenient to use.

[0057] Preferably, such as Figure 7 As shown, it also includes a reinforcing bar spacer 70, which has a main body 71 and a clamping structure 72, the clamping structure 72 being fixed to the reinforcing bar. Multiple sets of reinforcing bar spacers 70 are arranged horizontally on the same reinforcing bar structure. Preferably, the reinforcing bar spacers 70 are located between the reinforcing bar mesh 60 and the fair-faced concrete formwork 10, the clamping structure 72 engaging with the reinforcing bars of the reinforcing bar mesh 60, while the main body 71 abuts against the fair-faced concrete formwork 10, to form a good supporting and stable relationship.

[0058] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
