Description
Technical field
The invention belongs to degree control sides in technical field of building construction more particularly to a kind of lattice column work progress
Method.
Background technique
Lattice column is used as bending component, is chiefly used in mill building frame column and detached column, section is generally fashioned iron or steel plate design
Axial symmetry in pairs or singly symmetric sections.Grid-system component is by limb part and sews material and forms, and limb part is primarily subjected to axial force, sews material
Main lateral force resisting (for limbs axial direction).Lattice column, which sews material form, mainly lacing and batten plate.The knot of lattice column
Structure feature is, material area is arranged to the place remote apart from the axes of inertia, and can guarantee enhances component under the conditions of same axial drag
Anti-bending strength, and save material.Height is required to its perpendicularity deviation when lattice column is constructed, needs to examine at any time in work progress
It surveys, however construction requirement is often not achieved to the control of the perpendicularity of lattice column deviation in work progress in the prior art, in turn
Influence construction quality.
Summary of the invention
Above-mentioned background technique there are aiming at the problem that, the purpose of the present invention is to propose to vertical in a kind of lattice column work progress
Control method is spent, it is convenient to find perpendicularity of lattice column deviation at any time in the construction process and be modified at any time for deviation, it is full
Sufficient stand column pile construction quality requirement.
The technical solution that the present invention solves technical problem is as follows:
Degree control method in a kind of lattice column work progress of the present invention, it is fixed that the bottom end of the lattice column is provided with suspension column
Position otic placode, the specific steps of which are as follows:
Step 1: measuring for verticality steel plate is welded on the top of lattice column, if at suspension column chucking lug Board position being A point, lattice
Structure top end is B point, and the top of measuring for verticality steel plate is C point, and A point to the length between B point is Lab, and B point is between C point
Length be Lbc, it is that B point is to the actual measurement perpendicularity deviation of C point section on measuring for verticality steel plate that M, which is surveyed, and actually lattice column is practical vertical by M
Straight degree deviation；
Step 2: will weld, integral lattice column and measuring for verticality steel plate construct and measurement verticality is examined at any time
B point to the perpendicularity deviation of C point, i.e. M on steel plate is surveyed to survey；
Step 3: according to the length ratio relationship of the numerical value surveyed of M in step 2 and lattice column and measuring for verticality steel plate,
Show that the practical perpendicularity deviation of lattice column, i.e. M are real by conversion；
Step 4: survey carries out correction processing to lattice column if the numerical value of the M reality in step 3 exceeds construction requirement, until
Lattice column meets construction requirement.
It is further improved as technical solution, the measuring for verticality steel plate is channel steel or angle steel.
It is further improved as technical solution, the M is real to meet following relationship: M reality=M survey × Lab/Lbc with M survey.
It being further improved as technical solution, correction processing is carried out by jack in the step 4, and the one of lattice column
End is fixed, and the other end loosens, and is adjusted lattice column in fixing end, until the lattice column is vertical, is then fixed by locator, to mixed
It is withdrawn after solidifying soil initial set.
Compared with prior art, its construction letter of degree control method in a kind of lattice column work progress of the present invention
It is single, convenient, it can effectively ensure that construction speed, and easily find perpendicularity deviation at any time in lattice column work progress,
It is modified at any time for perpendicularity deviation simultaneously, meets the requirement of stand column pile construction quality, reduced the overall costs such as artificial, reduce
The labor intensity of construction personnel, improves labor productivity, has good practicability.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and specific embodiments:
