Description
Technical field
The present invention relates to a kind of construction techniques, in particular, relate to a kind of many uniform purlin thin pull bar installation methods of long-span roofing.
Background technology
At present, in steel house surface construction, it is frequently encountered by the support strength into increasing roof purline, between every two purlins, is vertically all placed equidistant two to four pull bars, after pull head is typically inserted through the connecting hole that two purlins are reserved, two ends nut is fixed, and will form entirety by purlin two-by-two.Pull bar normal length is about 1 to 2m, the pull bar quantity of whole Roof system configuration is many, owing to purlin wall is thin and many with roof girder junction point, pull bar diameter is relatively thin (general diameter is at about 12mm) in addition, is difficulty with carrying out after ground assembles the installation method of burst lifting.And conventional project way is to use the method installed by root to carry out in place, install because of pull bar and belong to work high above the ground, pull bar lifting is in place and be arranged on each junction point to be repeated once more, and safety rope often shifts and is once both needed to untie reset, cause efficiency of construction ratio relatively low, construction period will extend, and construction cost increases.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, and provide a kind of on the premise of roofing pull bar is more, improve transport and the installment work efficiency of pull bar, reduce many uniform purlin thin pull bar installation methods of long-span roofing of construction cost.
Many uniform purlin thin pull bar installation methods of the long-span roofing of the present invention, including following construction procedure:
Step one roof purline inspection:
According to design requirement, check roof girder and the installation procedure of roof purline and quality；
Step 2 arranges pull bar roofing conveying arrangement:
Roof purline longitudinal pitch is set to 1 ~ 2m, according to roof purline spacing dimension and the weight of pull bar, use cable testing bridge horizontal on the longitudinal direction of four roof purlines of roofing, and it is vertical with roof purline longitudinal centre line, by the groove of cable testing bridge, upwards and both ends open Plate Welding seals, the roofing conveying arrangement of one upper opening of composition；
Step 3 arranges seat belt:
Side at the everywhere contact position of roofing conveying arrangement and four roof purlines, it is respectively provided with one and is fixed on seat belt on roofing conveying arrangement, when making pull bar in transport or install, the track that four workmens vertically move all can be worn safely the seat belt without untiing；
The transport of step 4 pull bar and installation:
nullDescribed roofing conveying arrangement once can transport four roof purlines of covering，Between two roof girders, lay equidistant four piece roof purline 6 pull bars are set altogether，During pull bar transport,Everyone is gap bridge in the middle of roof girder with roof purline one by one to arrange four workmens,And wear the seat belt being arranged on roofing conveying arrangement,Each column at roof girder with hoisting apparatus by 6 pull bar handlings to roofing conveying arrangement groove,Then four people press the position that pull bar is arranged in roof purline longitudinal center,Common promote roofing conveying arrangement to after the installation site of pull bar，Pull bar is penetrated in roof purline by technical size requirement,Every workmen is responsible for installation and the fastening of pull-rod nut in this running orbit,The pull bar having circulated these four roof purlines successively is installed,The most whole roofing pull bar is all installed.
Roofing conveying arrangement bottom portion of groove in described step 2 respectively installs a position-limited wheel.Described position-limited wheel and roof purline side clearance are 2 ~ 3mm, play the restriction that the longitudinally running track of roofing conveying arrangement is anti-deviation.Described cable testing bridge specification is 300 × 100mm.Described pull bar quality is 1 ~ 2kg.The described a length of 6m of roofing conveying arrangement, quality is 180kg.
The invention has the beneficial effects as follows: (1) achieves the Fast Installation of pull bar, improve efficiency of construction, save the engineering time；(2) improve transport and the installment work efficiency of pull bar, reduce construction cost.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
In the drawings, many uniform purlin thin pull bar installation methods of the long-span roofing of the present invention, including following construction procedure:
Step one as shown in Figure 1, 2, roof purline inspection；According to design requirement, check roof girder 1 and the installation procedure of roof purline 2 and quality；
Step 2 as shown in Figure 3,4, arranges pull bar roofing conveying arrangement；Roof purline 2 longitudinal pitch is 1 ~ 2m, pull bar 6 is single weighs about 1 ~ 2kg, according to roof purline 2 spacing dimension and the weight of pull bar 6, the cable testing bridge selecting 300 × 100mm is horizontal on the longitudinal direction of four roof purlines 2 of roofing, and it is vertical with roof purline 2 longitudinal centre line, by the groove of cable testing bridge, upwards and both ends open Plate Welding seals, the roofing conveying arrangement 3 of one upper opening of composition；
Step 3 as shown in Figure 4,5, arranges seat belt；In roofing conveying arrangement 3 and the side of the everywhere contact position of four roof purlines 2, it is respectively provided with one and is fixed on seat belt 5 on roofing conveying arrangement 3, when making pull bar 6 in transport or install, the track that four workmens vertically move all can be worn safely the seat belt 5 without untiing；
As shown in Figure 5,6, pull bar transports and installs step 4；nullDescribed roofing conveying arrangement 3 once can transport four roof purlines 2 of covering，Described roofing conveying arrangement 3 length about 6m，Between two roof girders 1, lay equidistant four piece roof purline 26 pull bars 6 are set altogether，6 pull bars 6 weigh about 12kg，Roofing conveying arrangement 3 weighs about 180kg，Roofing conveying arrangement 3 equipped with pull bar 6 always weighs about 200kg，When pull bar 6 transports,Everyone passes a bridge with roof purline 2 one by one in the middle of roof girder 1 to arrange four workmens,And wear the seat belt 5 being arranged on roofing conveying arrangement 3,Each column at roof girder 1 with hoisting apparatus by 6 pull bars 6 handling to roofing conveying arrangement 3 groove,Then four people press the position that pull bar 6 is arranged in roof purline 2 longitudinal center,After the common installation site promoting roofing conveying arrangement 3 to pull bar 6，Pull bar 6 is penetrated in roof purline 2 by technical size requirement,Every workmen is responsible for installation and the fastening of pull bar 6 nut in this running orbit,The pull bar 6 having circulated these four roof purlines 2 successively is installed,The most whole roofing pull bar 6 is all installed.
Roofing conveying arrangement 3 bottom portion of groove in described step 2 respectively installs a position-limited wheel 4.Described position-limited wheel 4 is 2 ~ 3mm with roof purline 2 side clearance, plays the restriction that the longitudinally running track of roofing conveying arrangement 3 is anti-deviation.
