Description

The thin pull bar mounting method of the uniform purlin of long-span roofing many

Technical field

The present invention relates to a kind of construction techniques, in particular, relate to the thin pull bar mounting method of the uniform purlin of a kind of long-span roofing many.

Background technology

At present, in steel house surface construction, often running into the support strength for increasing roof purline, between every two purlins, vertically two to four pull bars being all equidistantly set, after pull head passes the reserved connecting hole of two purlins usually, two ends nut is fixed, and will form entirety by purlin between two.Pull bar normal length is about 1 to 2m, the pull bar quantity of whole Roof system configuration is many, because purlin wall is thin and many with roof girder tie point, pull bar diameter comparatively thin (general diameter is at about 12mm) in addition, carries out the mounting method of burst lifting after being difficult to realize ground assembling.And conventional project way adopts the method for installing by root to carry out in place, install because of pull bar and belong to work high above the ground, pull bar hoisted in position and be arranged on each tie point want multiple multiple once, and safety rope is often shifted and once all needs to untie to reset, cause efficiency of construction lower, 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 under a kind of prerequisite more at roofing pull bar is provided, improve transport and the installation work efficiency of pull bar, reduce the thin pull bar mounting method of the uniform purlin of long-span roofing many of construction cost.

The thin pull bar mounting method of the uniform purlin of long-span roofing of the present invention many, comprises following construction sequence:

The inspection of step one roof purline:

According to designing requirement, check installation procedure and the quality of roof girder and roof purline;

Step 2 arranges pull bar roofing conveying arrangement:

Roof purline longitudinal pitch is set to 1 ~ 2m, according to the weight of roof purline spacing dimension and pull bar, adopt cable testing bridge horizontal on the longitudinal direction of roofing four roof purlines, and it is vertical with roof purline longitudinal centre line, by the groove of cable testing bridge upwards and both ends open Plate Welding seal, composition a upper opening roofing conveying arrangement;

Step 3 arranges safety belt:

In the side of the everywhere contact position of roofing conveying arrangement and four roof purlines, all arrange one and be fixed on safety belt on roofing conveying arrangement, making pull bar when transporting or install, in the track that four constructors vertically move, all can wear safely the safety belt without the need to untiing;

The transport of step 4 pull bar and installation:

Described roofing conveying arrangement once can transport covering four root roof purlines, between two roof girders, lay four equidistant roof purlines 6 pull bars are set altogether, during pull bar transport, everyone is pass a bridge across in the middle of roof girder with roof purline one by one to arrange four constructors, and wear the safety belt be arranged on roofing conveying arrangement, often arranging 6 pull bar handlings across roof girder place lifting gear in roofing conveying arrangement groove, then four people press the position that pull bar is arranged in roof purline longitudinal center, after common promotion roofing conveying arrangement to the installation site of pull bar, pull bar is penetrated in roof purline by technical size requirement, every constructor is responsible for the installation of pull-rod nut in this running orbit and fastening, circulated successively these four roof purlines pull bar install, and then by above method, 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 longitudinal running orbit of roofing conveying arrangement is anti-deviation.Described cable testing bridge specification is 300 × 100.Described pull bar quality is 1 ~ 2kg.Described roofing conveying arrangement length is 6m, and 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 installation work efficiency of pull bar, reduce construction cost.

Detailed description of the invention

Below in conjunction with accompanying drawing, the invention will be further described.

In the drawings, the thin pull bar mounting method of the uniform purlin of long-span roofing of the present invention many, comprises following construction sequence:

Step one as shown in Figure 1, 2, roof purline inspection; According to designing requirement, check installation procedure and the quality of roof girder 1 and roof purline 2;

Step 2 as shown in Figure 3,4, arranges pull bar roofing conveying arrangement; Roof purline 2 longitudinal pitch is 1 ~ 2m, the single heavy about 1 ~ 2kg of pull bar 6, according to the weight of roof purline 2 spacing dimension and pull bar 6, select the cable testing bridge of 300 × 100 horizontal on the longitudinal direction of roofing four roof purlines 2, 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 seal, composition a upper opening roofing conveying arrangement 3;

Step 3 as shown in Figure 4,5, arranges safety belt; In the side of the everywhere contact position of roofing conveying arrangement 3 and four roof purlines 2, all arrange one and be fixed on safety belt 5 on roofing conveying arrangement 3, making pull bar 6 when transporting or install, in the track that four constructors vertically move, all can wear safely the safety belt 5 without the need to untiing;

As shown in Figure 5,6, pull bar transports and installs step 4, described roofing conveying arrangement 3 once can transport covering four root roof purlines 2, described roofing conveying arrangement 3 length is about 6m, between two roof girders 1, lay four equidistant roof purlines 26 pull bars 6 are set altogether, 6 pull bar 6 heavily about 12kg, roofing conveying arrangement 3 heavily about 180kg, roofing conveying arrangement 3 gross weight that pull bar 6 is housed is about 200kg, when pull bar 6 transports, everyone is pass a bridge across in the middle of roof girder 1 with roof purline 2 one by one to arrange four constructors, and wear the safety belt 5 be arranged on roofing conveying arrangement 3, often arranging the handling of 6 pull bars 6 across roof girder 1 place lifting gear in roofing conveying arrangement 3 groove, then four people press the position that pull bar 6 is arranged in roof purline 2 longitudinal center, behind the installation site of common promotion roofing conveying arrangement 3 to pull bar 6, pull bar 6 is penetrated in roof purline 2 by technical size requirement, every constructor is responsible for the installation of pull bar 6 nut in this running orbit and fastening, the pull bar 6 of these four roof purlines 2 of having circulated successively is installed, and then by above method, whole roofing pull bar 6 is all installed.
