CN2323050Y - Space triangular reinforced concrete slab-truss - Google Patents

Abstract

The utility model discloses a space triangular reinforced concrete board-truss, which is characterized in that a board (1) and two upper chords (2) are made into integration, and form an inverted space triangular with a plurality of diagonal web members (3) and a lower chord (4). Due to the fact that the board and the truss are made into integration by using reinforced concrete and a space triangle structural style is provided, the utility model is not only caused to combine the functions of a board frame and the truss into integration but also the latent energy of the material is fully played, and therefore, utilizing the small means to span the wide span is obtained. The utility model has the characteristics of low cost, no subsequent maintenance, small structural height, high durability, big applicable span (the maximum can reach 60m), no specific fabricate requirement and easy fabrication. The utility model can be used for roofs or floors of the building engineering.

Description

Spatial triangle armored concrete slab-truss

The utility model relates to the roofing element of construction work, the roof system of particularly a kind of plate-truss unification.

Roof structure form as large span is a lot, commonly used steel mesh frame, book web grider is arranged, answers concrete roof system, swallow shape plate, flap etc. in advance.Wherein, though the steel mesh frame is in light weight, moulding good, cost height, later maintenance expense are also high; Book web grider cost is low, but the span corresponding less (in the 18m) that is suitable for; Answer the concrete roof system to exist then that the roof truss height is big, the problem of poor durability in advance; And swallow shape plate, flap poor durability not only, suitable span is also corresponding less.

The purpose of this utility model is: the roof structure of a kind of plate-truss unification is provided, and the roof structure cost of this plate-truss unification is low,, good endurance little without later maintenance, structure height, be suitable for span big (maximum can reach 60m), no special facture requirement.

Embodiment of the present utility model: it is a kind of armored concrete slab-truss that is spatial triangle, comprises plate (1), upper chord (2), diagonal web member (3), lower chord (4); Be characterized in that plate (1) is made as one with two upper chords (2), and constitutes inverted spatial triangle with a diagonal web member (3) and a lower chord (4).

In above-mentioned spatial triangle armored concrete slab-truss, described diagonal web member (3) is four one group.

Compared with the prior art, the utility model is owing to adopt steel concrete that plate and truss are made as one, and a kind of spatial triangle form of structure is provided.The function that makes the utility model not only collect grillage, truss is the whole body, and has given full play to the potential of material, has accomplished to utilize primary structural component to cross over large span.Have that cost is low, little without later maintenance, structure height, good endurance, be suitable for span big (maximum can reach 60m), no special facture requires, makes easy characteristics.Can be widely used in the roof system or superstructure of construction work.

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

Accompanying drawing 1 is an organigram of the present utility model;

Accompanying drawing 2 is a kind of plane structure arrangement diagrams that use installment state of the present utility model;

Accompanying drawing 3 is 1-1 views of accompanying drawing 2;

Accompanying drawing 4 is 2-2 views of accompanying drawing 2;

Accompanying drawing 5 is A-A views of accompanying drawing 4;

Embodiment: shown in the accompanying drawing 1 is a kind of armored concrete slab-truss that is spatial triangle, comprises grillage (1), upper chord (2), diagonal web member (3), lower chord (4); Be characterized in that grillage (1) is made as one with two upper chords (2), and constitutes inverted spatial triangle with diagonal web member (3) and lower chord (4).Per four one group of diagonal web member (3), the group number can be decided according to the size of span.This plate-truss adopts steel concrete to make, and cost is low, without later maintenance, and with plate and frame with after being one, the plate (1) between upper chord (2) is an enclosed structure, participates in arrangement works again.

In actual use, spatial triangle armored concrete slab-truss can be pressed shown in the accompanying drawing 2 and be provided with at interval, between per two Pin spatial triangle armored concrete slab-truss prestressed cored slab, little frid or glass dome skylight etc. can be set, can reach the purpose of utilizing primary structural component to form large span.

The utility model adopts the supporting of winding up shown in accompanying drawing 3,4 when mounted, and it and beam etc. are common forms a three-dimensional system, and last string section is pressurized when working, and out-of-plane rigidity is big, has improved stability of structure.In addition, owing to adopt the supporting of winding up, roof system or superstructure need not use support system, have also increased the globality of roof system or superstructure simultaneously.

Claims (2)

1, spatial triangle armored concrete slab-truss comprises plate (1), upper chord (2), diagonal web member (3), lower chord (4); It is characterized in that: plate (1) is made as one with two upper chords (2), and constitutes inverted spatial triangle with a diagonal web member (3) and a lower chord (4).

2, spatial triangle armored concrete slab-truss according to claim 1 is characterized in that: described diagonal web member (3) is four one group.
