Description

A kind of bamboo-PVA concrete combined structure booth frame

Technical field

A kind of bamboo-PVA concrete combined structure booth frame, for the structural framework of planting greenhouse, belongs to agriculture project construction applications.

Background technology

Current agriculture project structure greenhouse, has bamboo wood to make easily, and complicated that have steel pipe manufacturing, the former need to often repair and even again build, and the latter's cost is higher and is unsatisfactory for life requirement.

Utility model content

The purpose of this utility model is in that to provide that a kind of simple in construction, cost be low, the bamboo-PVA concrete combined structure booth frame of long service life.

For achieving the above object, this utility model adopts the following technical scheme that a kind of bamboo-PVA concrete combined structure booth frame, including fringe truss and arched girder, described fringe truss adopts PVA concrete for making, described arched girder adopts T-shaped cross section bamboo profile to make, described fringe truss top adopts T-slot mouth, and described arched girder is affixed with the T-slot mouth of described fringe truss;

The bamboo profile in described T-shaped cross section is formed by one flat plate bamboo wood and two pieces of L-type bamboo wood gluings.

Described fringe truss is two, and the bamboo profile in described T-shaped cross section is one, and common combination forms single Pin greenhouse shelf structure.

The material of described fringe truss is PVA concrete.

Be not limited to connect node form, according to fringe truss, T-shaped cross section arched girder, fringe truss compound mode form described bamboo-PVA Combined concrete scaffolding structure.

Beneficial effect: this utility model adopts fringe truss, the bamboo profile in T-shaped cross section, fringe truss to form a single Pin frame, and fringe truss adopts PVA concrete material, the combination of multiple single Pin frames forms booth structure, not only cost is low, and simple in construction, long service life, cost is low.

Accompanying drawing illustrates:

Fig. 1 is the schematic diagram of fringe truss;

Fig. 2 fringe truss top T-slot mouth;

The bamboo profile in T-shaped cross section in Fig. 3;

Fig. 4 is single Pin frame;

Fig. 5 is the booth space structure after combination.

Detailed description of the invention

Below, in conjunction with example, substantive distinguishing features of the present utility model and advantage are further described, but this utility model is not limited to listed embodiment.

The L-type bamboo wood 4 that bamboo slab rubber material is converted into according to flat board 3 is together, form the bamboo profile 5 in T-shaped cross section as arched girder material, PVA high tenacity cement-base concrete is adopted to make fringe truss 1 arch structure, then the structure adopting T-slot mouth 2 connects, form the frame of arcuately greenhouse structure, such as Fig. 4, shown in Fig. 5, the combination of multiple single Pin frames forms the agent structure for planting greenhouse as shown in Figure 5, there is good practicality and endurance quality, T-shaped arch material has the bending resistance in maximum the moment of inertia plane, fringe truss 1 domes have the stability in its plane and bearing capacity, it is a kind of reliable plane combination version of structural behaviour.

Sum up the experience that booth is built, and adopt rational structural design, use high performance material simultaneously, meet functional requirement to greatest extent, be the purpose to reach of this utility model.

The above is only preferred implementation of the present utility model; it should be pointed out that, for those skilled in the art, under the premise without departing from this utility model principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
