Detailed Description
As shown in fig. 1-4, the invention relates to a construction method of an antique attic with a steel structure, which comprises the following steps:
step 1: the method comprises the steps of establishing an antique attic 1 and a three-dimensional model drawing of a scaffold at the periphery of the antique attic 1 by using BIM, determining a rod piece installation position of the scaffold, and enabling the position of a rod piece of the scaffold to be kept away from the position of a steel member of an eave.
Step 2: and erecting scaffolds layer by layer around the periphery of the antique attic 1, and installing the steel structure cornice 10 layer by adopting a sequential method with each layer of scaffold as a platform along with the erection of each layer of scaffold.
The scaffold erecting step is as follows: with every layer of floor 2 of loft building set up multirow pole setting 3 as the strong point, connect through the fastener between pole setting 3 and set up horizontal pole 4 and vertical horizontal pole 5, pole setting 3, interval between horizontal pole 4 and the vertical horizontal pole 5 sets up according to scaffold frame requirement and construction needs, wherein upwards extend to the upper strata as the lower floor pole setting 3 of 3 supports of upper pole setting, the lower floor pole setting 3 that does not regard as 3 supports of upper pole setting extends to between the two-layer steel construction eaves 10, preferentially set up 1.5m upwards to this layer of steel construction eaves 10 mouth, thereby avoid lower floor pole setting 3 to influence the construction of upper steel construction eaves 10. Utilize to draw to one side 6 from 3 horizontal slants of beginning of outside pole setting and the 7 drawknot of steel column of archaize building to one side 6 every two steps of three strides set up one, the horizontal inclination of draw to one side 6 is no longer than 45, draw to one side 6 and every row of pole setting 3 pass through the fastener be connected, can't be connected with pole setting 3 junction to one side 6 and horizontal horizon bar 4 or vertical horizon bar 5 are connected.
And 3, step 3: after the installation of the uppermost steel structure cornice 10 is completed, the roof is firstly constructed and engraved by adopting a reverse construction method from top to bottom, then the construction of the steel structure cornice 10 glazed tile roof and the installation construction of the steel structure cornice 10 lower curtain wall are carried out layer by layer, and after the construction of each layer of steel structure cornice 10 glazed tile roof and the steel structure cornice 10 lower curtain wall is completed, the scaffolds are dismantled layer by layer from top to bottom, so that a construction operation surface is provided for the construction of each layer of steel structure cornice 10.
Further, because steel column 7 can't be directly connected with diagonal draw bar 6, embrace four short steel pipes 8 that are the groined type and arrange outside steel column 7, four two liang of short steel pipes 8 are connected through the fastener, and diagonal draw bar 6 is connected through two fasteners with short steel pipe 8.
Safe dense meshes are hung on the vertical rods 3 and the transverse horizontal rods 4 on the outer sides of the scaffold. Set up the backing plate on every floor 2, pole setting 3 stands on the backing plate, protects floor 2, avoids the scaffold frame to set up and causes the destruction to archaize loft 1.
Set up multichannel bridging 9 at scaffold frame outside both ends, corner and middle interval no longer than 15m, bridging 9 leads to long the setting along scaffold frame direction of height, and bridging 9 passes through the fastener with pole setting 3 and horizontal pole 4 and is connected.
The scaffold boards are laid on each layer of operation layer by the transverse horizontal rods 4 and the longitudinal horizontal rods 5, the protective handrails are arranged above the scaffold boards at positions 1.2m above each layer of operation layer, and the protective handrails are connected with the vertical rods 3.
A safety pocket net is arranged below the scaffold board, so that construction safety is guaranteed, and falling objects and personnel are prevented from falling.
This application adopts to combine to the method of doing in the same direction as doing the way and reverse construction, and the successive layer carries out under steel construction cornice 10 erection construction, the roof of carving on gold or silver on the crest roofing and the construction of cornice glazed tiles roofing, the steel construction cornice 10 curtain wall erection construction, avoids the member and the steel construction cornice 10 of scaffold frame to collide each other, influences the structure construction.
In addition, utilize 2 structures on every layer of floor of 1 ancient imitation attic to set up the tower scaffold structure of upwards contracting to be suitable for the construction of 1 buildings in ancient imitation attic, replace wall spare and steel column 7 drawknot through diagonal draw bar 6, and with diagonal draw bar 6 and every row of scaffold structural connection, solve the great problem of 7 intervals of steel column, guarantee the stability of scaffold.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
