Description
Technical Field
The invention belongs to the technical field of building construction, and particularly relates to a method for reinforcing a multi-layer box type board house.
Background
In recent years, global disasters have been abused, and during outbreaks, the number of closely contacting persons, diagnosed patients and other persons needing isolation observation is huge, so that a large amount of small temporary independent living spaces are needed to meet the isolation use requirements. In order to meet the requirement of quick construction, box-type board rooms are mostly adopted for the temporary residential facilities.
The box-type board house uses glass rock wool as a heat insulation material, has natural heat insulation, can effectively isolate the external temperature and the internal temperature, and prevents the internal temperature from leaking; and the box board house outside adopts the steel keel design more, has good crushing resistance, can prevent the striking to protect its overall structure, sturdy and durable. Due to the fact that the box-type board house has a plurality of advantages and is often used as the first choice when epidemic situation outbreak occurs, 18m can be achieved through operations such as dismantling and opening holes of the wall boards of the box-type board house2、27m2And 36m2And the like, in a plurality of settings of rooms having different areas.
Considering that the isolation needs to be as long as 14 days or even 21 days, all the supporting functional facilities in the box-type board room should meet the requirements, such as finished bathroom, bed and wardrobe, but the arrangement of the facilities easily causes the overload of the box-type board room. The load of the conventional box-type board house is 200kg/m2If exceed this load, lead to box board house bottom to appear inhomogeneous the deformation easily, lead to the built-in article slope of box board house, have the potential safety hazard and pleasing to the eye inadequately, consequently, how to carry out reinforcement construction to current box board house structure in order to satisfy the problem that needs solve in urgent need at present.

and 4, step 4: two or more layers of structure reinforcement;
the second and above structures are reinforced by adding secondary corrugated square tubes above the decorative surface layer at the top, rigidly welding hanger rod square tubes between the secondary corrugated square tubes and the original lower C-shaped steel of the box-type board house, reversely transmitting the lower load to the upper secondary corrugated square tubes, and jointly bearing the indoor load by the upper and lower structures;
and 5: and carrying out concealed acceptance, installing indoor facilities after acceptance is qualified, continuously accepting after the indoor facilities are completely finished, and putting into use after acceptance is qualified.
Further, the method also comprises the step of reinforcing the secondary keel of the bottom plate in the box-type board house, and the specific method comprises the following steps: demolish the former box-type board house floor in the overweight district of local load to consolidate the bottom plate secondary joist, encrypt the setting according to the mode of double arranging, increase many times stupefied square pipe, encrypt the completion back, lay surface course cement pressure plate, keep the aesthetic property of box-type board house.
Furthermore, after the two-layer or above structure reinforcement is completed, a small steel plate is added at the supporting leg placing position of various heavy facilities in the box-type board house, so that the stress concentration of the floor layers of the box-type board house is avoided.
Further, the steel column is a galvanized steel pipe with the diameter of 48mm and the wall thickness of 3.2mm, and the size of the square steel plate is 100 multiplied by 3 mm.
Furthermore, the section size of inferior stupefied square pipe is 80X 60X 4mm, and the section size of jib square pipe is 20X 40X 3 mm.
Further, the size of the small-sized steel plate is 100 × 100 × 4 mm.
Furthermore, in the box-type board room reinforcing process, during welding, fireproof carpets are laid on the ground, fire extinguishers are arranged around the carpets, and the welding seams are subjected to rust prevention and corrosion prevention treatment.
The invention has the following beneficial effects:
after the box-type plank house is reinforced by the reinforcing method, when the local load in the box-type plank house exceeds the design load, the use requirement can still be met on the premise of ensuring the structure safety, the problems of uneven deformation, inclination of built-in articles and the like can not occur, and the box-type plank house is good in overall aesthetic property, safe and reliable.
