Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to a composite formwork that does not require dismantling and a composite formwork that does not require dismantling with steel reinforcement mesh. Background Technology

[0002] In building construction, certain building components often need to be cast on-site due to structural requirements. During casting, a template of the corresponding shape is installed around the component to form an inner cavity with the same shape as the component. Flowable concrete and other grouts are then poured into the inner cavity.

[0003] In the existing pouring process, the outer formwork is mostly made of wood or steel. The formwork needs to be erected before pouring and dismantled after pouring, which seriously affects the construction cycle of the building project and wastes a lot of wood and steel plates, thus increasing the construction cost. Utility Model Content

[0004] To solve the above problems, the present invention adopts the following technical solution:

[0005] A composite template that can be dismantled without dismantling includes a composite template body, on which a plurality of slurry discharge holes are uniformly arranged.

[0006] Furthermore, the composite non-removable template body is also provided with support holes and / or hoisting holes and / or junction box holes.

[0007] Furthermore, the composite non-removable template body is provided with multiple self-tapping screw mounting holes.

[0008] Furthermore, the end face of the composite non-removable template body is a right angle or an oblique angle.

[0009] Furthermore, the composite non-removable template body includes:

[0010] An interface layer, wherein the interface layer is a bonding layer with concrete;

[0011] A surface layer, wherein the surface layer is disposed on the side of the interface layer away from the concrete;

[0012] An isolation layer is disposed on the side of the surface layer away from the interface layer.

[0013] A composite formwork-free steel reinforcement mesh frame, employing any of the aforementioned composite formwork-free templates, wherein the composite formwork-free steel reinforcement mesh frame comprises a plurality of composite formwork-free steel reinforcement mesh frame units, and each composite formwork-free steel reinforcement mesh frame unit comprises:

[0014] Steel mesh frame;

[0015] Template connecting bar, one end of which is fixedly connected to the non-threaded end of a self-tapping screw or bolt, and the other end is fixedly connected to the steel mesh frame;

[0016] The composite non-removable template is fixed to the steel mesh frame by the threaded end of the self-tapping screw or the threaded end of the screw;

[0017] The steel reinforcement mesh includes vertical steel bars, horizontal steel bars and connecting steel bars. Both ends of the vertical steel bars are provided with connecting sections, and the ends of the connecting sections are provided with hooks for mesh installation and connection.

[0018] The horizontal reinforcing bars are Z-shaped or O-shaped steel sections.

[0019] Furthermore, the joints of the composite formwork-free steel mesh unit are coated with adhesive, and a mesh fabric is placed on the outside of the adhesive.

[0020] Beneficial effects:

[0021] This invention integrates the template with the building components, eliminating the need for disassembly, thus reducing the construction period and the amount of timber and steel plates required, thereby lowering construction costs.

[0022] To prevent voids, air is vented at the height of the concrete pour (when used vertically) by setting grout drainage holes on the wall panels.

[0023] By setting mesh cloth and shims on the template and fixing the template to the non-removable steel mesh frame with self-tapping screws or bolts, the tensile strength is increased.
