Abstract
The utility model relates to a high strength hot house steel-concrete framework, it has many vertical steel-concrete to encircle piece and many vertical pull rods, and vertical steel-concrete encircles a piece and is formed by the half-arch overlap joint of two symmetries, and steel-concrete encircles a piece arch top in the circular arch of same span, vertical pull rod is tied up on steel-concrete encircles a piece, and steel-concrete encircles a cross section and is the rectangle, respectively has a reinforcing bar in four angles of rectangle. The utility model discloses no longitudinal tie hole, it is fixed to bind, has not only simplified with the fixed procedure of reinforced concrete arch piece, easy to assemble and dismantlement, avoided the stress concentration problem of encircleing moreover, under with the specification condition, improved bearing capacity, practiced thrift raw and other materials, reduced manufacturing cost.
Description
Technical field the utility model belongs to a kind of highstrenghtpiston's booth steel reinforced concrete framework.
Background technology Patent Gazette for Utility Models on February 16th, 2005 discloses the utility model patent of CN2678342Y, " armored concrete greenhouse frame ".The greenhouse frame of this patent is by many arcual components and many longitudinal ties that are fixed on the every arcual component, skeleton that arcual component is made by many reinforcing bars and the concrete of pouring into a mould on skeleton constitute, the upper surface of arcual component cross section is a shiny surface, longitudinally has the longitudinal tie hole on the every arcual component.The characteristics of this greenhouse frame are convenient disassemblies, cost is low than the steelframe member, shortcoming is that arch is low flat, approximate circular arch, the longitudinal tie hole is opened in main force part such as vault in addition, greatly reduce the ability of arcual component load-bearing, particularly be easy to form stress and concentrate, reduced its intensity in the place of perforate.
Is in the modern installations agricultural of principal mode now with the booth, and many crops need frame that suitable shear strength is arranged, so that satisfy the requirement of hanging as watermelon east this very large fruit of melon and some special equipments.But but do not have in the prior art the corresponding solution of this problem.
The summary of the invention the purpose of this utility model is to propose a kind of supporting member not open the longitudinal tie hole, unstressed concentration problem, and manufacturing cost is lower, and highstrenghtpiston's booth steel reinforced concrete framework of more reasonable structure is to solve the deficiencies in the prior art.
This highstrenghtpiston's booth steel reinforced concrete framework that the utility model proposes, it has many vertical steel reinforced concrete arch parts and many longitudinal ties, it is characterized in that described vertical steel reinforced concrete arch part is formed by the semiarch spare overlap joint of two symmetries, steel reinforced concrete arch part vault point is in span cycloidal arch, be the vault outline line on circular arch line with span, described longitudinal tie is tied up on steel reinforced concrete arch part.
The vertical section of steel reinforced concrete arch part has 30-90cm to insert ground, and 50-100cm is arranged on the ground.
Steel reinforced concrete arch part cross section is a rectangle, in four angles of rectangle a reinforcing bar is arranged respectively.
The long limit of steel reinforced concrete arch part rectangular cross section is 7cm, and minor face is 5cm.
Longitudinal tie is working of plastics, steel reinforced concrete spare or metalwork, is shaped as rectangular strip, flute profile strip or tubular.Quantity is the 3-5 root.
The utility model compared with prior art, owing to cancelled the longitudinal tie hole, use the fixing mode of binding instead, not only simplified fixed routine with steel reinforced concrete arch part, be easy for installation and removal, and avoided the problem of stress concentration of arch part, at same specification, under the situation with cross section, improved the ability of bearing load greatly, and under the identical situation of bearing capacity, can reduce to encircle the cross sectional dimensions of part greatly, and save material, reduce and produce this.
Appended drawings 1 is the utility model front view.
Accompanying drawing 2 is the utility model left view (parts).
Accompanying drawing 3 is steel reinforced concrete arch part front views (semiarch spare).
Accompanying drawing 4 is steel reinforced concrete arch part A-A profiles (during amplification).
Among the accompanying drawing 1-4, the label of each parts is as follows:
The 1-connecting bolt; The 2-longitudinal tie; 3-ties up rope; 4-steel reinforced concrete arch part; The 5-above-ground route; 6-arch part connecting hole; The 7-reinforcing bar.
Embodiment as shown in drawings.Steel reinforced concrete arch part (4) adopts reinforcing bar (7) and some thin wires of four diameter 3.1mm to pull, mix routinely than making the semiarch spare that the rectangular cross section specification is 5 * 7cm with No. 525 cement, sand, rubbles, portion at overlap joint separates two both sides of encircleing part connecting holes (6) and being distributed in vault point symmetrically, the outline line of vault is on the circular arch line with span, look more top and higher, can bear more load like this than circular arch.Two semiarch spares are fixed into complete steel reinforced concrete arch part with connecting bolt (1) overlap joint, with the interval of about 1-1.5m many steel reinforced concretes arch parts are inserted or be embedded in about 30-90cm place under the above-ground route (5), this example is 70cm, and the ground compacting of should going ahead of the rest is in order to avoid subside.The vertical section that 1m is arranged on above-ground route.After the arch part stands well, three longitudinal ties (2) are fixed on the every arch part with tying up rope (3) binding along vault point and bilateral symmetry ground.Tie up rope and be common rope or iron wire.Longitudinal tie is ordinary tap water metal tube or plastic tube, and steel reinforced concrete vertical bar longitudinal tie also can use, and effect is constant.For ease of booth heat radiation and ventilation, sometimes can be at two longitudinal ties of outside colligation of arch part.
After this routine greenhouse frame was carried out, span was 3.5-6m, and free height is 2-3.2m, plastic sheeting, big The part such as canopy door is identical with existing technology. Through for a long time on probation, this booth frame has been obtained as follows Effect:
1, every mu of booth construction investment has reduced more than 50% than steel frame construction, is easy to promote;
2, long service life was estimated greater than 30 years, was 2-3 times of metal frame;
3, non-corrosive need not be painted, and reduces use cost;
4, load-carrying ability is strong, is 2-3 times of steel frame construction;
5, can do by cold drought ring, can plant paddy rice or fruit;
6, wind damage resisting, anti-snow disaster ability are strong;
7, heat absorptivity is low than steel frame construction, the plastic foil of can not burning, and the long service life of film is more than 2 times of steel construction film.
