Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an assembly template and construction method for structural columns at the edge of floor slabs. Background Technology

[0002] According to the specifications, if there is a secondary structural wall at the edge of the floor slab, a structural column must be installed in accordance with the specifications. However, during the primary structural construction phase, while the external scaffolding is still in place, many projects forget to install structural columns at the edge of the floor slab because structural columns are usually not shown in the construction drawings. After the external scaffolding is removed, it becomes difficult to set up the formwork for the structural column at the edge of the floor slab, making it extremely difficult to install the structural column at this location. This is hard to remedy later, causing many projects to simply abandon the construction of this structural column, which violates the construction specifications and leaves a significant safety hazard.

The L-shaped inner template (1) includes an inner template one (101) and an inner template two (102) rotatably connected to the inner template one (101); the outer template (2) includes an outer template one (201) and an outer template two (202) inserted into the outer template one (201); the outer template one (201) is connected to the inner template two (102) by bolts (9), and the outer template two (202) is connected to the inner template one (101) by bolts (9); The upper surfaces of the inner template 1 (101) and the inner template 2 (102) are provided with extended templates that can be placed against the bottom surface of the upper floor slab (10), and the upper surfaces of the outer template 1 (201) and the outer template 2 (202) are provided with extended templates that are higher than the upper floor slab (10) and can fit against the outer wall of the upper floor slab (10). The upper surfaces of the inner template 1 (101), the inner template 2 (102), the outer template 1 (201), and the outer template 2 (202) are all provided with extended template edges (7), forming a square frame. One side of the outer template 2 (202) is bent inward at 90° to form a bend, and the inner wall of the bend is inserted into the outer wall of the outer template 1 (201). The inner wall of the bent portion of the outer template 2 (202) is provided with a plurality of mortises (204), and the outer wall of the outer template 1 (201) is provided with tenons (203) corresponding to the mortises (204). The fixed frame (4) includes a diagonal bar connecting the lower floor slab (11) and the L-shaped inner template (1), and a horizontal bar connecting the diagonal bar and the L-shaped inner template (1) is provided on the diagonal bar, and a vertical bar connecting the horizontal bar and the lower floor slab (11) is provided on the horizontal bar. Each of the inner template 1 (101) and the outer template 2 (202), and the inner template 2 (102) and the outer template 1 (201) is provided with a screw hole (12) that matches each other.

2. The assembly template for structural columns at the edge of floor slabs according to claim 1, characterized in that, Handles (8) are provided on the outer walls of the inner template 1 (101), the inner template 2 (102), the outer template 1 (201), and the outer template 2 (202).

3. A construction method for structural columns at the edge of floor slabs, using the assembly template for structural columns at the edge of floor slabs as described in any one of claims 1 or 2, characterized in that, The method includes the following steps: Step S1: After measuring and laying out the lines, first install a fixed frame (4) on the lower floor slab (11), assemble the inner template 1 (101), inner template 2 (102) and outer template 1 (201) that have been coated with release agent, and connect the inner template 1 (101), inner template 2 (102) and outer template 1 (201) to the fixed frame (4) with a safety rope, and then fix the side wall of the inner template 2 (102) to the fixed frame (4); Step S2: Install another fixing frame (4) on the lower floor slab (11) and fix the side wall of the inner template (101) to the fixing frame (4); Step S3: Connect the outer template 2 (202) to the fixed frame (4) with a safety rope, insert the outer template 2 (202) into the outer template 1 (201), and fix the outer template 2 (202) to the inner template 1 (101); Step S4: Measure the distance between the two outer templates (2), the L-shaped inner template (1) and the upper floor slab (10), process the extension templates that are inserted into the upper end face of the L-shaped inner template (1) and can be pressed against the bottom surface of the upper floor slab (10), process the extension templates that are inserted into the upper end face of the two outer templates and can be attached to the outer wall of the upper floor slab (10), apply release agent to the inner side of all extension templates, and install all extension templates; Step S5: Install the grouting hopper (5) at the grouting port reserved on the inner side template (1) of the L-shaped template; Step S6: Pour self-compacting concrete into the formwork through the grouting hopper (5); Step S7: When the concrete pouring is completed and reaches the required curing age, remove the grouting hopper (5) and remove the excess concrete at the grouting port; Step S8: First remove the outer formwork 2 (202), then remove the outer formwork 1 (201) and the L-shaped inner formwork (1), remove the extension formwork attached to the upper surface of the outer formwork (2) and the L-shaped inner formwork (1), and finally remove the fixing frame (4) to complete the construction of the structural column.
