On the construction site, in order to facilitate communication and work, we have summarized some commonly used nouns and “numbers”, and these nouns and “idioms” can only be truly understood by knowledgeable people because of their professionalism, so the so-called engineering “jargon” system has been formed over time.
The sign size shall comply with the provisions of the modular system.

Function: make the construction surface of the two construction stages bond firmly.
What is chiseling? It is to chisel out dents on the completed concrete structural surface.
The focus of quality control shall be pre controlled in advance.
What is napping? After the cement mortar is brushed on the wall, a tool like a brush is used to pull the cement mortar into the shape of a little like an ice cream tip.
One post with two responsibilities: in the construction project, it refers to a specific post with dual responsibilities, emphasizing the safety responsibilities of each post, that is, the job responsibilities and safety responsibilities of the post.

What are the sign size, structure size and actual size? (1) The sign size is used to mark the distance between building positioning axes (bay, depth), and the size between the boundaries of building products, building components, and related equipment positions.
Three works: during each construction process, the technical and quality inspection personnel shall: pre construction technical disclosure, in-process inspection and guidance, and post construction summary and evaluation.
6.
9.
The construction size is less than or greater than the sign size.
One certificate and two certificates: the materials used in the project must have formal factory certificates, material certificates and test sheets that pass the spot check.
In metal technology, corresponding to hot working, cold working refers to the processing technology that can cause plastic deformation of metal below the recrystallization temperature, such as cold rolling, cold drawing, cold forging, stamping, cold extrusion, etc.
Cold working is suitable for machining metal parts with small section size and high requirements for machining size and surface roughness.
So the Supervisor knows the meaning of the following “jargon” frequently used on the construction site? Commonly used noun 1.
“Three treasures” refers to the wearing and installation of safety helmets, safety belts and safety nets.
It also refers to the three controls of “quality, progress and investment”.
14.
Cold working has great resistance to deformation, which can be used to improve the hardness and strength of the workpiece while forming the metal.
Three talks: three talks about safety during construction: talk about safety precautions before starting work; Focus on safe operation during construction; After the work is finished, comment on today’s safety situation and lessons learned.
(2) Flat bricks are called sleeping bricks; Brick side vertical masonry is called bucket brick.
13.
Three electricity: electricity, telecommunications, radio and television facilities..
2.
2.
If we say “four controls”, add safety.
Three inspections: self inspection, mutual inspection, handover inspection or special inspection during construction.
What is hair throwing? Shaving, also known as spraying, is to use a special spray gun to spray cement mortar with small sand with adhesive on the structural layer, so that the paint layer and the structural layer are firmly bonded, and no hollowing of the paint layer will occur.

What are running bricks and header bricks? What are sleeping bricks and bucket bricks? (1) Straight brick refers to the length of the brick along the wall; Ding brick refers to the width of the brick along the wall.
11.
(2) Structural dimension is the design dimension of building products and building components.
Let the concrete bond firmly.
Generally, in the cast-in-place structure, after the cast-in-place slab is poured, roughen it and pour the next layer of column wall.
What is cold working? Generally, it refers to metal cutting, that is, cutting tools are used to cut off redundant metal layers from metal materials (blanks) or workpieces, so that workpieces can obtain a certain shape, dimensional accuracy and surface roughness.
Three principles: openness, fairness and impartiality.
Three guarantees: general requirements for construction: quality, safety and progress.
Generally, the structure size plus the reserved gap size or minus the necessary support size equals to the sign size.

The advantages are flexible partition of buildings and less material consumption; The disadvantage is that the rigidity is poor, and the window opening of the exterior wall is limited.

4.
The advantages are that the transverse walls are dense, so that the transverse stiffness is large, the seismic resistance is high, the flexibility of opening windows on the external wall is large, and it is easy to organize the ventilation; The disadvantage is that the amount of materials used is large, and the size of the bay is not flexible enough.
One machine, one box, one switch and one leakage protector: it refers to the requirements for the safety of on-site machines and equipment: one electrical equipment shall have a special switch box, and the switch box shall have an isolating switch (one switch) and a leakage protector.
What are horizontal wall bearing, vertical wall bearing, and mixed vertical and horizontal wall bearing? (1) Transverse wall bearing refers to placing beams or slabs on the transverse wall.
The function is to prevent the wall from being too smooth to generate orderly reflection of sound and light, which is mostly used in public places.
Three controls: refers to the control during the construction process: pre control, in-process control and post control.
Three networks: telecommunication network, broadband network and television network.
The difference between the actual size and the structural size shall be the allowable building tolerance value.
