1.Quantity calculation rules.
2.Related Notes:
Determination of beam length:When the beam is connected with the column, the beam length is calculated to the side of the column; When the main beam is connected with the secondary beam, the length of the secondary beam is calculated to the side of the main beam
2) When the ring beam is connected to the lintel, it should be listed separately. When the beam is connected with a concrete wall, the length of the beam should be calculated to the side of the concrete wall
3) Foundation beam refers to the beam located on the foundation or cushion and connected to an independent foundation, strip foundation or pile cap.
2020 test question] According to the "Code for Quantity Calculation of Housing Construction and Decoration Engineering" (GB50854-2013), the correct calculation of the quantity of cast-in-place concrete lintel is ( ).
a.Beam heads protruding into the wall are counted in the beam volume.
b.The beam pads in the inner part of the wall are itemized by other component items.
c.The volume occupied by the reinforcement in the beam is deducted.
d.Calculated according to the centerline shown in the design drawing.
Correct answer a
Answer analysis This question examines cast-in-place concrete engineering. Cast-in-place concrete beams include foundation beams, rectangular beams, special-shaped beams, ring beams, lintel beams, arc beams (arch beams) and other projects. According to the size shown in the design drawing, the volume is calculated by "m3", and the volume of steel bars and embedded iron parts in the component is not deducted, and the beam head and beam pad protruding into the wall are merged into the beam volume.
