Abstract

The utility model relates to a heat storage composite wall body used in a sunlight greenhouse. The composite wall body comprises a sand soil wall body with a cement board covered on the surface thereof. Since the surface of the composite wall body is covered with a cement board, the wall body has high structural strength, long service life, low manufacturing cost and strong heat storage and is suitable for being constructed and popularized for use in a sand area.

Description

A kind of heliogreenhouse accumulation of heat combined wall

(1) technical field

The utility model relates to the body of wall technical field, particularly a kind of simple in structure, with low cost, long service life, the heliogreenhouse accumulation of heat combined wall that heat storage capacity is strong.

(2) background technology

The structure of passive type heliogreenhouse is a printing opacity in the south at present, and east, west, three in north are body of wall.The body of wall of heliogreenhouse is a big heat storage, plays a part actively in the greenhouse, and the thermal environment in the greenhouse is had direct influence.A part of solar radiant energy of body of wall savings on daytime is discharged in the air night when fine; During the cloudy day, main thermal source is exactly the heat radiation of body of wall.

The body of wall of heliogreenhouse is different from construction wall, because its body of wall thicker (generally greater than 60cm), and highly lower (generally between the 2m-3m) since the mid-80, and the thermal isolation and heat storage performance of heliogreenhouse body of wall is the focus of a research all the time.Improving greenhouse temperature, heat stability can realize by improving wall body structure greatly.Traditional greenhouse wall body structure often is difficult to satisfy the requirement of higher thermal isolation and heat storage.Adopt heliogreenhouse construction cost height, the heat storage capacity of brick wall poor; The Heterogeneous Composite body of wall greenhouse that in body of wall, adds various thermal isolation and heat storage materials, good heat insulating, but cost height, the peasant is difficult to accept; The intensity of soil property buttress cob wall body is too low, and service life is lower, is subject to the influence of sleety weather, and this body of wall also is not suitable for building in the sandy soil area simultaneously.

(3) summary of the invention

The utility model is in order to solve heliogreenhouse body of wall cost height, heat storage capacity difference or the low problem of structural strength, and a kind of simple in structure, with low cost, long service life, heliogreenhouse accumulation of heat combined wall that heat storage capacity is strong are provided.

The utility model is realized by following measure: a kind of heliogreenhouse accumulation of heat combined wall comprises that surface coverage has the sandy soil body of wall of cement board.

The beneficial effects of the utility model:

1. surface of wall is coated with cement board, structural strength height, long service life.

Low, the heat storage capacity of body of wall cost strong, suit to build and apply in the sandy soil area.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the structure principle chart of heliogreenhouse.

(5) specific embodiment

A kind of heliogreenhouse accumulation of heat combined wall comprises that surface coverage has the sandy soil body of wall of cement board.

At first sandy soil are poured water in order to solve the not sticking problem of sandy soil, sandy soil become wet after coagulation hardening, just pile up neatly wall then, and body of wall adopts up-narrow and down-wide trapezium structure.In order to guarantee that body of wall has good accumulation of heat and stability, should control the 2.5-3m that goes to the bottom, on push up about 1.5m, high 1.8-2m.After body of wall had been piled up neatly, taking advantage of wets cut the type of being cut into body of wall as early as possible.In order to prevent loose the collapsing in sandy soil body of wall exsiccation back, outsourcing cement board topping under the body of wall leather hard, the long 60cm of cement board, wide 40cm, thick 5cm.At last, water mud in slit is filled floating between cement board.

Heliogreenhouse shown in Fig. 1,4, comprise north wall body, southern body of wall, gable 12, rear column 7, middle standing pillar 8, scarp slope plastic covering overlay film 9, have greenhouse inlet 14 on the gable 12, be coated with wall outside cement backplate 3, wall top cement backplate 4, side cement backplate 5 within the walls on the north wall surface, be coated with southern side cement backplate 10 on gable 12, the southern surface of wall.

During manufacturing; fill out in the combined wall under the protective effect of composite wall wall outside cement backplate 3, composite wall wall top cement backplate 4, the inboard cement backplate 5 of composite wall from the indoor sandy soil that dig out 2 in greenhouse; play insulation and accumulation of heat effect; flooring, greenhouse 6 is hanged down about 0.8 meter than north side, greenhouse outdoor ground 1; the sandy soil that dig out are filled out in the trapezoidal wall; cement backplate 10 lower ends, southern side are hanged down about 0.8 meter than southern side, greenhouse outdoor ground 11; effect is to prevent that sandy soil from collapsing, and gable 12, composite wall wall push up passageway 13, all bind with cement board.

As shown in Figure 4, heliogreenhouse one side can be set up workplace 17, and its medium temperature chamber's inlet 14, workplace inlet 15, workplace outlet 16 all are common wooden doors.

Shown in Fig. 2,3, while the water filling of banketing in the work progress prevents that the sandy soil in the trapezoidal wall body of wall are loose, and is easy to moulding.

Claims

1. a heliogreenhouse accumulation of heat combined wall is characterized in that: comprise that surface coverage has the sandy soil body of wall of cement board.
