Abstract

The utility model discloses a roof supporting bottom plate, which is rolled and integrally formed by a steel plate, and comprises a bottom plate part (1), I vertical ribs (2) and II vertical ribs (3) which are positioned at two sides of the bottom plate part (1), wherein I horizontal folded edges (21) are outwards bent on the I vertical ribs (2), and the tail ends of the I horizontal folded edges (21) are vertically bent to form I lap edges (22); the II vertical ribs (3) are outwards bent to form II transverse folding edges (31), and the tail ends of the II transverse folding edges (31) are perpendicularly bent to form II overlapping edges (32). The roof supporting bottom plate is directly fixedly connected with the decorative roof plate after being mutually lapped, has simple and compact structure and simple and convenient installation, can replace the function of purlins, and is widely applied to the field of architectural decoration.

Description

A kind of roofing supports base plate

Technical field

The utility model relates to a kind of roofing and supports base plate.

Background technology

In traditional roof structure, adopt normally that spacing is provided with some purlins on the main structure beam, plank or concrete building board are fixed on the mode on the purlin, yet along with the development of structural metal material and processing and application techniques, metal Roof has become the main flow form of contemporary bottom nonresidential building.The common way of existing metal Roof structure is to be weight tray with the profiled sheet, ornamental roof panel is set above, the smooth metal of one deck need be set between described profiled sheet and ornamental roof panel grab flat board, thereby cause the metal Roof complex structure, the space is not compact, be not easy to construction, and increased building costs greatly.

The utility model content

Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, a kind of simple and compact for structure, simple installation is provided, can replaces the roofing of purlin effect to support base plate.

The technical scheme that the utility model adopted is: the utility model is one-body molded by steel plate rolling, comprise base plate, be positioned at the upright rib of the upright rib of I, II of described base plate both sides, the upright rib of described I outwards is bent with I cross break limit, and described I cross break edge tail vertically is bent to form the I overlap edge; The upright rib of described II outwards is bent with II cross break limit, and described II cross break edge tail vertically is bent to form the II overlap edge.

Adjacent two roofings of the utility model support base plate and cooperate by the upright rib of described I, the upright rib overlap joint of II, and the height of the upright rib of described I is slightly less than the upright rib of II, and the width on described I cross break limit is slightly less than II cross break limit and matches with it.

Described base plate longitudinal separation is provided with at least two reverse shallow grooves.

The beneficial effects of the utility model are: overlap mutually owing to support base plate by the polylith roofing in actual roof structure, the surface forms a complete plane, above ornamental roof panel can be installed directly, can economize the structure of grabbing flat board except that metal, and the upright rib of the lap-joint of adjacent roofing support base plate can bear certain load, replace the function of purlin, described base plate longitudinal separation is provided with at least two reverse shallow grooves, can improve the amount of deflection and the bearing strength of base plate.The utility model is economized the structure of removing purlin, can directly assist to place on the main structure beam, and simple installation, firm, the pressure hole decorative panel that is equipped with particular design in addition forms succinct, a bright smallpox ceiling system as smallpox.

Fig. 2 is a schematic cross-section of the present utility model;

Fig. 3 is the structural representation of the utility model specific embodiment.

The specific embodiment

As shown in Figure 1 and Figure 2, roofing described in the utility model supports the upright rib 2 of I, the upright rib 3 of II that base plate comprises base plate 1, is positioned at described base plate 1 both sides, the upright rib 2 of described I outwards is bent with I cross break limit 21, and described I cross break limit 21 ends vertically are bent to form I overlap edge 22; The upright rib 3 of described II outwards is bent with II cross break limit 31, and described II cross break limit 31 ends vertically are bent to form II overlap edge 32; Described base plate 1 longitudinal separation is provided with at least two reverse shallow grooves 4, the amount of deflection and the bearing strength of base plate have been improved, the height of the upright rib 2 of described I is slightly less than the upright rib 3 of II, and the width on described I cross break limit 21 is slightly less than II cross break limit 31, is convenient to the overlap joint cooperation that adjacent two roofings support base plate.

The utility model is directly auxilliary to be placed on the main structure beam, the function that replaces purlin, in the present embodiment, the pressure hole decorative panel that cooperates particular design is as smallpox, form succinct, bright smallpox ceiling system, as shown in Figure 3, ornamental roof panel 5 is arranged on roofing and supports the upper strata of base plate and pass through holder 6 connections, be provided with waterproofing course 7 therebetween, ceiling 8 supports base plate with described roofing and directly fastens the location, has saved the necessary purlin of existing roof ceiling system or keel and suspender member thereof, makes to save material, cost reduces, and has saved the shared inside usage space of purlin or keel and suspender member thereof simultaneously; Described ceiling 8 supports base plate with described roofing and fastens the inner chamber 9 that forms a sealing, insulation be can lay in the described inner chamber 9 and heat, damping material protected, when guaranteeing that interior temperature is stable, also have the function that reduces indoor echo, make whole indoor environment not only succinctly but also quiet.

The utility model can be widely used in the architectural decoration field.
