Measures: What does the steel bar contain?

Question 1: What content does the measure steel bar contain? What content does the measure steel bar contain? Knowledge to ensure that the position of the steel bar is fixed, the steel bar, etc., increase the amount of steel bar, ensure the position of the steel bar in cast-in-place slabs, rafts, etc., increase the horse stool steel bar, cast-in-place beam double Arrange the steel bars to ensure the position of the steel bars, add pads, etc.

Question 2: What are the types of steel bars for measures? Generally speaking, any steel bar information not marked on the structural diagram is a measure steel bar.

Specifically speaking, the middle iron of the double-layer steel bar in the beam, the stirrup bar in the raft, and the bracing of the shear wall The steel bars and the template positioning bars of the frame columns are all measure steel bars

Question 3: What are the measure steel bars? In order to ensure that the steel bars in the drawings can be in the correct position after construction, the additional steel bars added by the construction personnel are called Measure steel bars.

Question 4: What is the measure rib and what is its function? The drawings do not show the reinforcement, but it must be used in actual construction. The most common reinforcement measures are the horse bench reinforcements of double-layer two-way slabs, and the pad reinforcements set for some large foundation beams to meet the thickness of the beam's protective layer (generally shown in the drawing instructions), which can also be designed according to the construction organization. The quantity of similar steel bars is generally determined by on-site visas issued by Party A and Party B as the basis for settlement.

Question 5: What are the steel bar engineering measures? This depends on the contract contracting method, that is, the basis for calculating the project price. If it is calculated based on the bid price, it should be taken into consideration when bidding. Once the bid is won, the quotation will generally not be changed; if the contracting method is based on the project budget, the budget fixed price already includes the consumption price of steel bars, support bars, etc., and cannot be calculated separately.

Question 6: The steel bar schedule contains measure bars. What does this measure bar mean? In order to ensure the position of the steel bars, fix the steel bars, etc., the amount of steel bars is increased. For example, the horse stool steel bars added to ensure the position of the upper and lower steel bars of cast-in-place slabs, rafts, etc.; in the cast-in-place beams, if there are double rows of steel bars, the pads added to ensure the position of the upper and lower steel bars, etc.

Question 7: What are the measures for positioning steel bars in the special management of steel bars? The theodolite method for locating the location of the building to be built is as follows: 1. The layout of the main control line of the plane axis. When first entering the site, first of all, according to The original city coordinate points provided by the Institute of Surveying and Mapping are combined with planning drawings and building plans to establish plane control lines. Generally, the two ends of the main control line are led to a fixed building or a solid concrete ground, and both ends must be visible. And avoid the location of foundation pit excavation. The main control lines are generally set to three vertically and horizontally to facilitate closing and checking. When checking the line, still keep the distance relative to the relationship between the balcony and the axis. Then spread the excavation line according to the arranged main control line. In this work, attention should be paid to the grading size and the operating rack distance reserved for the outer wall of the building. When excavation of foundation trench, whether there is a working surface left at the excavation line, grading should also be considered, and then the main attention should be paid to the control of elevation. 2. Establishment of elevation control network: Check whether the layout of the control network is reasonable. It is required that its position can reach the control points in each construction section and be visible to each other. During the inspection, the readings of the surrounding points should be consistent without moving the instrument. The construction unit is required to The relationship between the elevation of the control network and that given by the Surveying and Mapping Institute is also provided, as well as the relationship between plus and minus zero. 3. Experience in laying out lines 1. First of all, the purpose of setting out lines is for construction control and operation. It is mainly the construction control line. The plane line mainly controls the installation of the formwork and prevents walls. When closing the mold, the control line should be used. The wall edge line is mainly used to adjust the position of the steel bars and the protective layer. The elevation line is generally the building line 50, which mainly controls the floor height. It is used on the upper steel bars when supporting the roof board. Question 8: What should the control measures at the construction site include? 1. Control points

1.1 Whether the project department’s dust control management system is sound and implemented, the key lies in implementation.

1.2 Whether the funds for dust control are implemented, whether they are earmarked, and whether they are allocated and used in a timely manner.
