Embodiment Construction

[0031] Such as figure 1 , 2 , shown in 3 and 4: a kind of technology and method of Z-type purlin end connection, is to lap together two purlin 1 ends to be connected one by one up and down, and the upper and lower rows of bolt holes are made at the lap joint, and then Fix the two purlins 1 and the purlin supporting plate 2 together with multiple sets of bolt fastening components 3, and the purlin supporting plate 2 is seated on the house beam 4; it is characterized in that: the described bolt holes are round holes, The bolt and the bolt hole are fit without clearance.

[0032] In order to achieve a clearance-free fit, the bolt hole manufacturing process is as follows:

[0033] 1) For the convenience of description, the following settings are made;

[0034] a), set the plate thickness of the Z-shaped purlin 1 as δ;

[0035] b), setting the centerline distance of the two horizontal plates on both sides of the Z-shaped purlin 1, the height of the purlin is H;

[0036] c), se...

Abstract

The invention discloses Z-shaped end part connecting process and method, relating to building construction. End parts of two purlines (1) are lapped together up and down and then are fixed by using bolt fastening assemblies (3), bolt holes are round holes, and bolts are in zero clearance fit with the bolt holes. The bolt holes are prepared by the following steps of: positioning the bolt holes of the upper purline, wherein the upper end face of the purline is used as a positioning reference surface, the distance between the center line of the upper line of bolt holes and the reference surface is equal to the distance between the center line of the lower line of bolt holes and the center line of the upper line of bolt holes and is equal to H-2a; and processing all bolt holes on the upper purline according to the positioning; the positioning method of the bolt holes of the lower purline comprises the steps that, the upper end face of the lower purline is used as a positioning reference surface, the distance between the center line of the upper line of bolt holes and the reference surface is equal to the distance between the center line of the lower line of bolt holes and the center line of the upper line of bolt holes and is equal to H-2a; and processing all bolt holes on the lower purline according to the positioning.

Description

technical field [0001] The invention relates to a process method for house construction, in particular to a connection process and method for Z-shaped purlins used in steel structure board houses. Background technique [0002] Since the Z-shaped connecting purlin has the rationality of the force and good economy, more and more factory roof load-bearing purlins use the Z-shaped purlin. The purlin connection method is to overlap the ends one by one, and then use multiple sets of bolt fastening components to fix the two purlins and the purlin supporting plate together. Due to the wall thickness of the lap joints of the purlins, for the convenience of installation, the bolt connection holes are often made into long round holes at present. However, the oblong hole will make the stress distribution at the lap joint uneven, which will affect the selection of the section and the safety of the structure. Contents of the invention [0003] In order to solve the above-mentioned tec...
