The invention discloses a dining table and tea table assembling method. The dining table and tea table assembling method comprises the following steps: placing a surface glass fibre reinforced plastic cake on clean table cloth upwards; screwing bolts in the surface glass fibre reinforced plastic cake in place, and commonly screwing to the positions of 8 mm; then, sleeving and placing pipe fittings or upright posts; when a base is placed, aligning screw rods and assembling the screw rods at one time to prevent the surface of the base from being damaged by pressing; screwing nuts on the base to the tightest degree to ensure that the dining table and the tea table are stable and do not waggle after being assembled. If the dining table to be assembled is large and heavy, the base is lifted and placed down slowly during an overturning process after the dining table is assembled; if the operation is improper, the surface glass fibre reinforced plastic cake can be pulled down, the glass can be damaged; a glass fibre reinforced plastic product is required to be taken and placed slightly during assembling; sharp angles of the glass cannot be collided, or the glass can be damaged; if the product with a heavy base, the surface cannot be lifted directly so as to prevent the cake from falling off. The method is high in assembling efficiency and high in quality, and the safety of the dining table and the tea table is protected.
