Canopy, balcony, eaves arrangement and sectional details

When the risers of canopies and balconies are cast in situ, the minimum thickness should be 80, otherwise it is difficult to construct. The vertical bars should be placed on the plate.

Central. When making double ribs, the high weight < 900, and the minimum plate thickness is 100; Height 900, minimum plate thickness 120The riser of the balcony should be prefabricated as much as possible and welded with the embedded parts of the pick.

When there are inclined decorative plates on the canopy and balcony, the steel bars of the slabs are placed on top of the inclined plates, and the wall ring beams (i.e., double-layer reinforcements of the slabs) are anchored through the lower part of the horizontal slabs. The sealing plate on both sides can be plugged with Taibo board, and the steel bar is welded with the steel wire of Taibo board, so it is not necessary to use concrete structure. The window sill at the door and window of the balcony should be made of light material masonry, so that it can be chiseled off during future decoration.

When the length of the pick plate is greater than 2 meters, it is advisable to configure the structural reinforcement under the plate. The length of the upper rib of the inner span plate of the pick plate should be greater than or equal to the length of the overhang of the pick plate, especially when there is a concentrated load at the end of the pick plate. A small vertical edge should be added to the end of the inner pick plate to prevent dust from falling during cleaning.

When the rain overhang of the top balcony is unorganized drainage, the overhang length of the rain tie should be greater than the overhang length of the lower balcony 100There should be room for reinforcement of the pick plate, and large-diameter steel bars should be used to prevent bending. The span of the inner span of the pick plate is small, and there may be a negative bending distance in the middle of the span, and the negative reinforcement of the pick plate support should be extended over the full span.

Frame structure.

C20 concrete for regeneration. C20 resistance.

The pressure is 20 megapascals. Comply with the load standard of the frame.

Frame structure: Frame structure refers to the structure composed of beams and columns connected by rigid or hinged joints to form a load-bearing system, that is, a frame composed of beams and columns to resist the horizontal and vertical loads that occur in the application process. The walls of the houses with the structure are not load-bearing, only play the role of enclosure and separation, and are generally made of prefabricated aerated concrete, expanded perlite, hollow bricks or porous bricks, pumice, vermiculite, ceramsite and other lightweight plates and other materials masonry or assembly.

Its main advantage is that the building layout is flexible, which can meet the requirements of building use to a large extent. However, the lateral stiffness of the frame structure is small, and the ability to resist deformation under horizontal action is poor, and the horizontal displacement of the apex of the structure and the relative horizontal displacement between the layers are large under strong earthquakes. In order to meet the requirements of both load-bearing capacity and lateral stiffness, the column cross-section is often large, which is very uneconomical and reduces the usable area.

Therefore, the frame structure in the earthquake zone should not be too high.

The frame structure can be made of C20 concrete. The compressive strength of C20 is 20 megapascals. Meets the frame load bearing standard.

Frame structure: Frame structure refers to the structure composed of beams and columns connected by rigid or hinged joints to form a load-bearing system, that is, a frame composed of beams and columns to resist the horizontal and vertical loads in the application process. The walls of the houses with the structure are not load-bearing, only for enclosure and separation for congratulatory purposes, and are generally made of prefabricated aerated concrete, expanded perlite, hollow bricks or porous bricks, pumice, vermiculite, ceramsite and other lightweight plates and other materials to be built or assembled or swam in.
