Abstract
The utility model discloses a Z-shaped purlin end connecting device which relates to house construction. Two purlin ends are vertically overlapped together and are fixed with bolt fastening components, a bolt hole is a round hole, and non-clearance fit is adopted between a bolt and the bolt hole. The Z-shaped purlin end connecting device is firm for connecting, does not loose, is convenient for manufacturing, is suitable for overlapping the purlins of various specifications, and has large purlin bearing strength, good economic benefit and good values of promotion and use.
Description
Technical field
The utility model relates to building construction, is specifically related to the linkage of the Z type purlin of steel work board house use.
Background technology
Have stressed reasonability and good and economic because the Z type connects purlin, increasing factory building roof load-bearing purlin all adopts Z type purlin.The purlin method of attachment is that the end overlaps one on the other, with many group bolton assemblies two purlins and purlin supporting plate is fixed together again.Because there is wall thickness in the lap-joint of purlin, for easy for installation, bolt connecting hole is often made slotted hole at present.But the slotted hole place can make that the stress distribution of lap-joint is inhomogeneous, and then has influence on the selection in cross section and the safety of structure.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of Z type purlin end connecting device, and bolt hole is a circular hole, and bolt cooperates for no gap with bolt hole.
The utility model is realized with following technical scheme: a kind of Z type purlin end connecting device, be that two purlin ends to be connected are overlapped one on the other, lap-joint makes many up and down row's bolts hole, with many group bolton assemblies two purlins and purlin supporting plate are fixed together, described purlin supporting plate is seated on the house beam again; It is characterized in that: described bolt hole is a circular hole, and bolt cooperates for no gap with bolt hole.
Good effect of the present utility model is:
Tight completely when 1, Z-shaped purlin overlaps with regard to guaranteeing, be connected firmly, non-loosening, the purlin bearing strength is big.
2, bolt hole is a circular hole, and the bore size of all Z-shaped purlins is unified, and is easy to make, the production efficiency height.
3, be suitable for the overlap joint of all size purlin, have good economic benefit and popularizing value.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 is the utility model purlin scheme of installation;
Fig. 2 is the utility model purlin connection diagram;
Fig. 3 is position, a purlin hole schematic diagram on the junction;
Fig. 4 is position, a purlin hole schematic diagram under the junction.
Among the figure, 1, Z type purlin, 2, the purlin supporting plate, 3, the bolton assembly, 4, house beam.
The specific embodiment
Shown in Fig. 1,2,3,4: a kind of Z type purlin end connecting device, be that two purlin to be connected 1 ends are overlapped one on the other, lap-joint makes many up and down row's bolts hole, with many group bolton assemblies 3 two purlins 1 and purlin supporting plate 2 are fixed together, described purlin supporting plate 2 is seated on the house beam 4 again; It is characterized in that: described bolt hole is a circular hole, and bolt cooperates for no gap with bolt hole.
For realizing that no gap cooperates, bolt hole making skill is as follows:
1) for sake of convenience, does following setting;
A), the thickness of slab of setting Z type purlin 1 is δ;
B), the distance between center line of two level boards in setting Z type purlin 1 upper and lower both sides is that the height of purlin is H;
C), setting Z type purlin 1 upper and lower end face to adjacent one distance of arranging bolt hole center's line is a;
2) localization method of last purlin bolt hole:
A), with the purlin upper surface as the location datum;
B), arrange distance between bolt hole center's line and the datum on and be a+
C), the distance of arranging down between bolt hole center's line and the row of the going up bolt hole center line is H-2a;
D), process whole bolts hole of going up on the purlin according to above location;
3) localization method of purlin bolt hole under:
A), following purlin upper surface is the location datum;
B), arrange distance between bolt hole center and the datum on and be a-
C), the distance of arranging down between bolt hole center's line and the last row bolt hole center line is H-2a;
D), according to the whole bolts hole on the purlin under the processing of above location.
As shown in Figure 1: present embodiment bolton assembly 3 is two, according to Z type purlin 1 size, also can use many up and down rows, many bolton assemblies 3 of every row, its bolt hole positioning and processing method is identical, is that every row's bolt hole distance deducts 2a five equilibrium again by row's number.
