Description

Technical Field

[0001] The utility model belongs to the field of building structure construction, and in particular relates to a simple assembled ladder template. Background Art

[0002] During the process of supporting the formwork of building structures, it is often necessary to support and reinforce the staircase formwork. The staircase is inclined and has triangular steps, which makes it difficult to support the staircase formwork. Traditional staircase formwork is mainly supported and reinforced with nails and steel pipes. The front formwork of the step is generally nailed to the side formwork with nails, and the nails need to be removed when the formwork is removed. This practice of frequently nailing in and out nails causes great damage to the formwork, and the operation is complicated, labor-intensive and time-consuming. At present, there are also staircase formworks with detachable structures. However, during pouring, concrete easily flows into the gap of the detachable installation structure, making the formwork difficult to remove, thereby causing damage to the formwork.

[0062] Step 3: After all the step front baffles 1 are installed, the stair section side reinforcement device 3 is installed immediately; specifically, two vertical steel pipes 32 are arranged on the outside of the two stair section side baffles 2, and the two vertical steel pipes 32 are fixed to the horizontal steel pipe 31 by fasteners 33;

[0063] Step 4: pouring concrete for the stair section (when pouring, pour from the bottom to the top starting from the bottom step of the stair section);

[0064] Step 5: When the concrete of the stair section is finally set and reaches a certain strength, the side reinforcement device 3 of the stair section is removed;

[0065] Step 6: Take out the nails temporarily fixed between the side baffle plate 2 of the stair segment and the template 4 at the bottom of the stair segment, and gently tap the side baffle plate 2 of the stair segment toward the outside of the stair segment with a hammer to disengage the wooden square track 23 and the slot 15; separate the side baffle plate 2 of the stair segment from the concrete on the side of the stair segment;
