Abstract
The invention relates to a construction method for the interlayer replacement of structural system conversion. Under the precondition of ensuring the safety and the integral stability of the structure, the inveniton adopts a transnormal construction method for the interlayer replacement of a transverse structural system, including the steps: firstly, non-weight-bearing transverse members are processed by the operation of interlayer dismounting; secondly, the dismounted members are processed by the operation of steel structure replacement; and finally, vertical members bearing the structure is reinforced. The invention carries out the operation of interlayer separation according to the allocation of labor force, the same working procedure is carried out in different interlayers, and flow process of construction is executed to greatly accelerate the construction speed. Meanwhile, the clear height of a structure-bearing vertical structural post can be strictly controlled within the range of the height of two storeys in the dynamic process of the construction, therefore, the requirements of corresponding specification for the integral stability of the structure are met. Furthermore, the method for the interlayer replacement can simplify, program and informationize the management of a plurality of complex and interlaced working procedures of the construction and can effectively and reasonably connect the working procedures with one another, thereby playing the favorable role of engineering instruction.
Description
Technical field
The present invention relates to building when reconstruction, the method for employing system conversion is converted to the construction technology of steel framed structure with concrete frame structure, relates in particular to a kind of interlayer replacement job practices that is used for Program for structural Transformation.
Background technology
In building reconstruction process, different with the conventional new construction that we know, the construction technology of structure alteration work is based upon on the characteristics of structure reconstruction self often.When reconstruction relates to conversion construction category from the concrete frame structure system to the steel frame structural system, its construction content contains structural demolition usually, structure replacing, the working procedure of a series of complexity such as structural strengthening, and these operations intersect at when carrying out simultaneously in the same engineering, how targetedly, reasonably arrange to remove, displacement, reinforce overall construction process, how in existing structure small space scope, to solve a steel construction material transportation difficult problem, and how to finish displacement construction or the like, just become this class programming of restriction, cost, the important topic of quality and safety.
Summary of the invention
A kind of interlayer replacement job practices that is used for Program for structural Transformation provided by the invention, under the precondition of the safety of guaranteeing structure and resistance to overturning, adopted a kind of job practices of unconventional transversary system interlayer replacement, elder generation's interlayer is removed nonweight-bearing transverse member (concrete beam plate member), again the member of having removed is carried out the steel work displacement, carry out the vertical member of structure load-bearing at last and reinforce.The present invention at first carries out the division of interlayer according to labour's configuration, the same operation of in different interlayers, constructing simultaneously, and then launch flowing water construction operation, accelerating construction progress greatly.Can the strict clear height of vertical structure post in the construction dynamic process be controlled in two story height scopes simultaneously, satisfy the related specifications requirement of the stability of structural entity the structure load-bearing.The method of interlayer replacement can be staggered with numerous complicated in addition working procedure management simplification, sequencing, informationization can effectively reasonably be connected each procedure, have played the effect of excellent engineering directiveness.
In order to achieve the above object, the invention provides a kind of interlayer replacement job practices that is used for Program for structural Transformation, comprise following steps:
The construction lot number of step 1, division interlayer replacement, and interlayer is divided: the even level or the odd-level that are divided into some batches;
Step 2, first floor even level or the odd-level interlayer of setting carried out the dismounting of concrete structure transverse member;
Step 2.1, select artificial air compressor machine, mechanical cutter or chemical explosion to remove as required; According to the dismounting mode of selecting for use, strictly observe corresponding related specifications requirement in the demolishing process;
The rubbish of after step 2.2, dismounting finish lower floor being piled up such as concrete are cleared up transportation, and reinforcing bar in time reclaims;
Step 3, shelve a little setting: after treating that horizontal concrete component complete removal finishes, when carrying out interlayer replacement, the steel structure column member in the interlayer is carried out interim shelving temporarily;
Step 3.1, every post are provided with some brackets of shelving, and are used for the temporary fixed of outside steel pipe;
Step 3.2, the two semi-ring concrete steel pipes that will make are transported to the job site, cut interim pad, are shelved on the bracket, are welded as a whole again, and the slit between steel pipe and the concrete column is filled by the grouting material and reinforced;
The strengthening construction of step 4, outside steel pipe concrete column;
Interlayer in the described step 1 is divided, and divides according to the configuring condition of the personnel of unit in charge of construction, plant equipment, material and other resources.
In first floor displacement, continue the dismounting construction that flowing water carries out second batch even level or odd-level; Carry out the structural system displacement construction of second batch of floor after same dismounting finishes, carry out the dismounting of the 3rd batch of floor this moment synchronously, carries out by that analogy; After the displacement of whole even levels of phase I or odd-level finishes, carry out dismounting, the displacement construction of the odd-level at the same position of second stage again according to the sequence of construction circulation of step 2～step 5.
A kind of interlayer replacement job practices that is used for Program for structural Transformation provided by the invention, the conventional construction technology of displacement successively of comparing has following characteristics and advantage:
1, adopts the job practices of interlayer replacement, utilize these characteristics of interlayer, can dispose according to the labour, the same operation of in different interlayers, constructing simultaneously, and then launching the flowing water construction operation, the construction that utilizes the interlayer segmentation to carry out like this can be constructed by multiple spot, the progress of constructing has been accelerated in construction synchronously greatly.
2, by the method for interlayer replacement, numerous and diverse working procedure simplification, standardization, sequencing can be made to be connected in order between the operation, effectively avoided unnecessary doing over again.
