Description

Arch bar mounting and fixing assembly of multi-span greenhouse

Technical Field

The utility model relates to a link a big-arch shelter technical field, specifically be fixed subassemblies of arch bar installation of linking a big-arch shelter.

Background

The greenhouse is a facility which can transmit light, keep warm (or heat) and is used for cultivating plants. In seasons unsuitable for plant growth, the method can provide the growth period of the greenhouse and increase the yield, and is mainly used for cultivating or raising seedlings of plants like warm vegetables, flowers and trees in low-temperature seasons. In which the greenhouses can be classified into single-span greenhouses and multi-span greenhouses.

Present company's big-arch shelter, the both ends of arch bar are fixed in respectively on the lateral wall of the trapezoidal gutter of falling, the pressure that the arch bar received is whole to be concentrated on the lateral wall of gutter like this, this kind of connected mode is when the arch bar top receives sleet pressure, the compressive capacity of arch bar is lower, the arch bar is easily crushed or impaired, lead to the gutter to warp easily, lead to the big-arch shelter to collapse, current gutter compressive strength only relies on the gutter side to support, can't decompose pressure on whole gutter, cause, under the same material, the gutter compressive strength of present standard structure can't resist the pressure of 10 centimetre thickness snow.

The two ends of the arch bar are respectively fixed on the side wall of the gutter, so that the gutter not only plays a role in removing rainwater, but also plays a role in bearing the force transmitted by the arch bar. When the top of the arch bar is stressed, the arch bar has low bearing capacity, and the arch bar is easily crushed under the action of external force, so that the normal use of the multi-span greenhouse is influenced.

When strong snowfall occurs in 2009, 2019 and local areas when the gutter formed by bending the 2.0-thick galvanized plate is selected, the gutter is not pressed by snow, so that the whole multi-span greenhouse collapses, and huge economic loss is caused to agricultural production.

Based on this, the utility model designs kinds of arch bar installation fixed subassembly of linking a big-arch shelter to solve above-mentioned problem.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide kinds of fixed subassembly of arch bar installation of a big-arch shelter even to in solving the big-arch shelter even that proposes in the above-mentioned background art, the bearing capacity of the arch bar of the big-arch shelter that links now is lower, appears pressing the arch bar under the exogenic action easily and collapses, influences the problem of the normal use of a big-arch shelter even.

In order to achieve the above object, the utility model provides a following technical scheme:

Arch bar mounting and fixing component of multi-span greenhouse, comprising arch bar and several upright posts vertical to the ground, characterized in that the upper surface of the upright post is equipped with V-shaped groove, the upper part of the V-shaped groove is fixed with angle steel, the inner side of the angle steel is fixed with square tube, the end of the arch bar is fixed on the side wall of the square tube.
