Construction sequence and construction plan of brick concrete structure

Such a strip foundation is a brick foundation, and the steel bar only needs to be made as the upper geosphere beam, and the structural column is made from the geosphere beam; If there is an independent foundation construction, it is necessary to do a single foundation first, and generally there is a frame column that will be set up in this way.

Construction sequence: construction pay-off - foundation trench excavation - check the axis, elevation - pouring cushion concrete - maintenance - masonry stone foundation - ground ring beam.

A strip foundation is a form of foundation in which the length of the foundation is much greater than the width. According to the superstructure, it is divided into strip foundation under the wall and strip foundation under the column.

The length of the foundation is greater than or equal to 10 times the width of the foundation. Strip foundations are characterized by their arrangement on one axis and intersecting with more than two axes, and sometimes with independent foundations, but the cross-sectional dimensions and reinforcement are not the same. In addition, the transverse reinforcement is the main stressed steel bar, and the longitudinal reinforcement is the secondary stressed steel bar or the distributed steel bar.

The main stressed reinforcement is arranged below.

What is the specific content of the brick-concrete structure brick masonry construction plan, the following Zhongda Consulting will answer for you.

1. Construction preparation.

Materials & Main Equipment:

Bricks: The variety and strength grade must meet the design requirements, and have the factory certificate and test sheet. The bricks of the clear water wall should be uniform in color and luster, and the corners should be neat.

Cement: The variety and label should be selected according to the opening part of the masonry section and the environmental conditions in which it is located, and it is generally advisable to use No. 325 ordinary Portland cement or slag Portland cement.

Sand: With medium sand, the mud content of the sand used in the preparation of mortar below M5 does not exceed 10%, and the mud content of the sand of mortar above M5 does not exceed 5%, and the sand content of the mortar above M5 is not more than 5%, and it is sieved with a sieve with a 5mm aperture before use.

Admixture: white ash curing time is not less than 7d, or fly ash is used.

Other materials: wall tie bars and embedded parts, wood bricks should be brushed with preservatives, etc.

Main equipment: should be equipped with shovels, planers, brick knives, Dongzhou flats, supporting boards, wire sinkers, small white lines, tape measures, iron levels, leather rods, small buckets, ash troughs, brick ash, brooms, etc.

Working conditions: complete the outdoor and atrium backfill, and install the ditch cover.

Complete the hidden inspection procedures for foundation and foundation engineering.

According to the elevation, plaster the cement mortar moisture-proof layer.

Bounce the axis wall line, pop up the door and window opening position line according to the actual specifications and dimensions of the approach brick, and the experience line meets the design requirements, and complete the pre-inspection procedures.

According to the design elevation requirements, the piping rod should be erected, and the spacing of the piping rod should be 15 20m.

The mortar is tested by the laboratory, and the mortar is prepared for mold testing (6 pieces as a group).

Summary. 1. Foundation construction foundation:

Construction pay-off - foundation trench excavation - check the axis, elevation - pouring cushion concrete - maintenance - masonry strip foundation - ground ring beam.

2. Main structure:

Construction brick masonry masonry - structural column, ring beam reinforcement binding - structural column, ring beam formwork construction - plate formwork construction - plate reinforcement binding - pouring concrete.

What are the general construction processes of brick-concrete structures.

1. Foundation construction foundation: construction pay-off - foundation groove excavation - check the axis, elevation - pouring cushion layer concrete - maintenance - masonry strip foundation - ground ring beam 2, main structure: construction brick masonry masonry - structural column, ring beam reinforcement binding - structural column, ring beam template construction - plate template construction - plate reinforcement binding - pouring concrete responsibility:
