Description

A positioning locking support structure for metal roof

technical field

The utility model belongs to the field of metal enclosure systems for large-span steel structure buildings, in particular to a positioning locking support structure for a metal roof.

Background technique

Steel structure buildings are gradually becoming a substitute for concrete structures due to their advantages of light weight and high strength, rapid construction, green energy saving, and large-span shaping. In some special fields, they have become the mainstream of application. The roof system of the building also puts forward higher requirements. Metal roofing is widely used in my country as an important roofing system.

Metal roofs can not only achieve the normal wind and rain protection function, but also make the building have a stronger sense of modernity and the atmosphere of the times, and conform to the principle of green environmental protection and sustainable development, so it is widely used in airport terminals, large exhibition halls, gymnasiums, As well as the roofs of large modern public buildings such as new railway stations.

Among them, the metal roof standing seam system is the most widely used at this stage. The roof panel fixing method of this system is to clamp the roof panel on the plum blossom head of the fixing seat, and then lock the rib on the fixing seat with an electric overlocking machine. In this way, no perforation can be seen on the roof, instead of screw penetration, the support method is hidden under the roof panel, and the hidden danger of water leakage caused by nailing the metal roof in the early stage is solved. However, under this connection method, there is no direct and effective fixation between the roof panel rib and the plum blossom head of the fixed seat, so that a slidable metal roof system is formed. This leads to the following problems:

1. With the change of temperature, the metal roof system will bear greater temperature stress. Under the repeated stress of thermal expansion and cold contraction, the system will produce repeated expansion and contraction deformation and asynchronous slip. This is because the slidable metal roof system has no direct and effective fixation between the roof panel rib and the plum blossom head of the fixed seat. When the system undergoes repeated expansion and contraction, the two cannot correspond one by one, resulting in mutual dislocation and deviation. The original occlusal position is deviated, and positioning cannot be achieved. As a result, it is unfavorable to the original occlusal method and reduces the structural bearing capacity and wind resistance.

2. When the wind load acts on the roof, the flexural and shear bearing capacity between the plate and the plate, the plate and the support of the metal roof system is transmitted through repeated friction for a long time. However, in the existing slidable metal roof system, there is no direct and effective fixation between the plate and the plate, and between the plate and the support, which causes the wear of the roof plate and the plum blossom head of the fixed seat at the position of the fixed seat to become thinner and smaller, and even the fixed seat falls off. , so that the entire system cannot be locked, so that the wind resistance of the entire roof is reduced, and it is opened and destroyed under harsh weather conditions.

The working principle and process of the positioning and locking support structure of the metal roof proposed by the utility model:

As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, in the concrete construction process of the metal roof system of the present invention, firstly, the support device 2 is connected with the purlin 1, and the support device 2 adopts a triangular support seat 22 and a buckle The new type of non-sliding fixed seat combined with the clips 24 realizes the engagement of the supporting device 2 with the small rib 251 of the metal roof panel and the large rib 252 of the metal roof panel, which overcomes the slidable metal roofing system. There is no direct and effective fixation between the plum blossom heads of the seat. The buckle clip 24 is directly buckled and locked with the small rib 251 of the metal roof panel, and forms a new type of non-sliding fixed seat with the triangular support seat 22, so that the thermal expansion and contraction of the plate can pass through the slight deformation of the plate in each span. to digest. Since the new type of support device 2 formed by the triangular support base 22 and the buckle clip 24 supports the small ribs 251 of the metal roof panel, it is unnecessary for the underside of the metal roof panel to be in close contact with the supporting layer, so that there is more space under the metal roof panel. Good ventilation and ventilation conditions can better prevent corrosion of the board surface and increase corrosion resistance. At the same time, the triangular support seat 22 adopts a triangular form, which also improves the overall stability of the structure from the perspective of structural stress.

There are silicone protrusions 33, which enhance the contact friction force, so that the locking clip 31 can better clamp the large rib 252 of the metal roof panel. The locking splint 35 is connected to the positioning device 4 near the inner side of the upper part, and positioning grooves 42 are provided on both sides of the interior of the locking splint 35 . When the retractable sleeve positioning rod 41 is retracted to the point where the locking clip 31 and the top of the metal roof panel 25 are fastened, the length adjustment can be accomplished by rotating the thread 416 on the inner tube 412 of the retractable sleeve positioning rod 41 . When the length of the telescopic sleeve positioning rod 41 is adjusted to the length at which the locking clip 31 is clamped with the lower metal roof panel 25 that has been constructed, the position is positioned and the length is locked.
