Description

A kind of zigzag shape purlin and connection component being exclusively used in long-span roofing plate

Technical field

The utility model relates to a kind of zigzag shape purlins and connection component for being exclusively used in long-span roofing plate, belong to building work Journey technical field.

Background technique

Roof boarding is used in the construction material that roof load is directly born on building roof, is that various different building types must Standby building materials.With the continuous development of modern building technology, demand for the roof boarding of large span and require higher and higher.For Solve the problems, such as that the weight bearing power of long-span roofing plate or building bottom plate is inadequate, inventor, which devises, can be suitable for large span Open-type builds bottom plate.It is not only able to solve the problems, such as building bottom plate or roof boarding bearing load scarce capacity, but also can It substitutes time purlin and saves building cost.Meanwhile inventor has also been that novel opening type builds a variety of different types of companies of back-plane design Connection member and erection support.In use, inventor be found that while erection support have it is easy for installation, universal performance is good, The installations of a variety of suspention pendants can be adapted to, but since the quantity of support and build-up member is (referring to Fig. 1) on the high side, construction precision not In the case where height, often there is different degrees of difference in height in each support.For the installation effect for guaranteeing suspention pendant etc., erector People needs to be adjusted to find suitable installation site to the position of each support, this brings biggish work for construction Amount.Meanwhile constant depth is relatively shallower in the channel using T-type screw rod for open-type building bottom plate, although being able to bear absolutely mostly Several suspention pendants, but or stability requirement higher building higher for shockproof requirements, it is also necessary to further strengthen roof boarding, It builds bottom plate and suspends the stability of pendant in midair.

Utility model content

Erection support installation error for the existing open-type long span building bottom plate of solution or roof boarding is larger, position adjustment Inconvenience, larger workload, and the technical problem of suspention pendant stability difference, the utility model provide one kind and are exclusively used in greatly The zigzag shape purlin of span roof boarding, and the connection component containing the purlin.The technical solution taken is as follows:

A kind of zigzag shape purlin being exclusively used in long-span roofing plate, the purlin include integrally formed bottom surface 11, inclined-plane 12 With top surface 13, wherein bottom surface 11 is connect by the inclined-plane 12 of two sides flare with top surface 13；The bottom surface 11 and the top surface 13 are flat Row；The hole slot 15 linearly arranged along end face length direction is equipped on the top surface 13.

Preferably, the inclined-plane 12 of 11 two sides of bottom surface is identical as the tilt angle that bottom surface 11 is formed.

Preferably, the bending side 14 extended to 11 direction of bottom surface is equipped in the end face of the top surface 13.

It is highly preferred that the hole slot 15 is the strip of the composition of round, oval, square type or rectangle and circular arc.

A kind of connection component containing any zigzag shape purlin, which includes connector I2, connector The connecting rod of II3, connector III4 and concatenation fixedly connected part I2, connector II3, connector III4 and zigzag shape purlin 5；The connector I2 is Π type structure, and the distance between two parallel sides are greater than what open-type building back plate connections were formed Channel width, the non-parallel face of connector I2 are equipped with the through-hole for connecting connecting rod 5；The connector III4 is Π type knot Structure, parallel side are equipped with the reinforcing rib II41 of indent；Connector II3 equipped with perforation threaded hole 34 is set to connector III4's Between concave reinforcing rib II41；Connecting rod 5 sequentially passes through the hole slot 15, connector I2, connector II3 of purlin from the bottom to top, and It is fixed on the inside of the non-parallel face of connector III4.

Preferably, the connecting rod 5 passes through multiple nuts and purlin 1, connector I2, connector II3 and connector III4 is fixedly connected.

Preferably, the parallel side 21 of the connector I2 is equipped with reinforcing rib I23.

Preferably, the connector II3 is rectangular parallelepiped structure, is equipped with rectangular recess 31 in the bottom surface of connector II3；In square It is equipped with countersunk head slot 32 in connected in star 31, the threaded hole 34 for connecting connecting rod 5 is equipped in countersunk head slot 32.

Long-span roofing plate alleged by the utility model, large span open-type building bottom plate refer to patent CN 106948547 A, the building of sliding groove structure is spliced to form disclosed in CN 206144018U by two adjacent building chassis connection sections positions Bottom plate.

Compared with the existing technology, the beneficial effect that the utility model obtains is:

The alternative erection support of purlin is arranged along the conduit direction perpendicular to open-type building bottom plate, purlin can with it is more A building bottom plate or roof boarding are attached, and can be effectively reduced installation error.The position adjustment to large area is carried out is avoided, Adjustment is got up very convenient, can substantially reduce the workload of installation personnel, and a few word purlins also flexible radian adapts to more Anisotropic roofing.

Connection component containing zigzag shape purlin is arranged in the conduit of adjacent building back plate connections formation by three Connector with concatenate three connectors screw rod connect.Relative to T-type screw rod, the connection for being added significantly to building bottom plate is deep Degree improves building bottom plate and zigzag shape purlin and suspends the stability of pendant in midair.
