Assembly Instructions
The JEKCA building system features a patented interlocking brick-through mechanism that ensures a sturdy and durable final model. Each piece is secured using specialized screws, preventing the structure from easily breaking apart.
Preparation:
- Clear a large, well-lit workspace.
- Organize the building pieces by color and shape as much as possible. This will simplify the assembly process.
- Familiarize yourself with the included building manual. It contains detailed diagrams for each step.
Interlocking Mechanism Overview:

Image: Step-by-step diagram illustrating the JEKCA patented interlocking brick-through system. (1) Align two blocks. (2) Insert the specialized screws through the aligned blocks. (3) Rotate the screws 90 degrees to lock them securely in place.
- Step 1: Align Blocks - Position the plastic blocks according to the building manual's diagrams. Ensure the holes in the blocks align perfectly.
- Step 2: Insert Screws - Carefully insert the specialized screws through the aligned holes in the blocks.
- Step 3: Lock in Place - Using the provided tool (if applicable, or by hand), rotate the screws 90 degrees. This action expands the screw's base within the blocks, creating a secure, interlocking connection.
General Assembly Tips:
- Follow the building manual's sequence precisely. Each step builds upon the previous one.
- Double-check screw placement and rotation to ensure maximum stability.
- If a piece does not fit easily, do not force it. Re-examine the diagram and ensure correct orientation and piece selection.
- Take breaks if you feel fatigued. This is a detailed project that requires patience.
Maintenance
To maintain the appearance and integrity of your JEKCA model:
- Cleaning: Dust the model regularly with a soft, dry cloth. For deeper cleaning, gently wipe with a damp cloth and mild soap, then dry thoroughly. Avoid harsh chemicals or abrasive materials.
- Storage: Store the assembled model in a stable location away from direct sunlight and extreme temperatures to prevent material degradation or discoloration.
- Disassembly: If you need to disassemble the model, carefully rotate the screws back 90 degrees to unlock them before separating the blocks.
