Abstract
The utility mode relates to a steel-and-wood composite beam for molding and supporting a reinforced concrete member. The composite beam comprises a steel frame and a wood brace, wherein the wood brace is embedded in the steel frame in the steel frame rolling and manufacturing process. The steel frame is provided with a base plate, two side plates and two opening edge plates, wherein each opening edge plate is connected with one corresponding side plate to form an integrity, an included angle Beta is formed between the opening edge plate and the corresponding side plate; the base plate of the steel frame is of the indent circular arc surface; the two side plates are respectively provided with grooves embedded into the wood brace; and the included angle Beta formed by each opening edge plate and the corresponding side plate is more than or equal to 60 degrees and less than 90 degrees. In the composite beam, the steel frame is combined with the wood brace closely; the leveling is simple, convenient and easy to carry out in the using process; meanwhile, the composite beam has enough rigidity and strength and is not easily deformed, therefore, the repeated turnover using time is increased.
Description
Technical field
The utility model relates to a kind of shaping reinforced concrete member support device, and particularly a kind of shaping reinforced concrete member supports with steel wood composite beam, belongs to the realm of building construction.
Background technology
The domestic construction industry is built shaping reinforced concrete member and is mainly adopted method group mold formings such as wooden form, bamboo plywood, combined steel formwork at present.The use in light weight of wooden form or bamboo plywood is flexible, has certain advantage when building the reinforced concrete member of complicated shape, therefore domestic wooden form or the bamboo plywood method of adopting mostly when molding component.Wooden form or bamboo plywood self intensity is lower, needs stent support and fixing when the group mould, need use a large amount of wooden a tree, used in making timber for boats and form support.Because wooden form or bamboo plywood turnover access times are very low, also are difficult to recycling as the wooden a tree, used in making timber for boats that supports usefulness, cause the significant wastage of timber resources.There is a kind of shaping reinforced concrete member to support in the prior art and uses the wood composite a tree, used in making timber for boats, this technology has solved this problem to a certain extent, as shown in Figure 1, it is by C structural steel frame 2 ' and wooden a tree, used in making timber for boats 1 ' form, wood a tree, used in making timber for boats 1 ' be entrenched in C structural steel frame 2 ' in, with connector 4 ' by connecting hole 3 ' with C structural steel frame 2 ' with wooden a tree, used in making timber for boats 1 ' be fixed together.As shown in Figure 2, this kind structure the steel frame roll forming and with the chimeric process of wooden a tree, used in making timber for boats in because the effect bottom surface of stress can form the cambered surface of outward bulge, not only influence steel frame and the chimeric tight ness rating of wooden a tree, used in making timber for boats, in use also cause very big difficulty to its leveling.Wooden in addition a tree, used in making timber for boats and steel frame only depend on connector to fix, and its bonding strength is relatively low, in use through colliding with, steel frame outwards opens distortion easily, influences itself and the chimeric tight ness rating of wooden a tree, used in making timber for boats, causes steel frame to separate with wooden a tree, used in making timber for boats, thereby lost efficacy, shortened its turnover access times.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of shaping reinforced concrete member to support with steel wood composite beam, its steel frame is combined closely with wooden a tree, used in making timber for boats, in use leveling is simple and easy to do, and has enough rigidity, intensity, not yielding, repeat to have enough to meet the need access times thereby improve.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of shaping reinforced concrete member supports with steel wood composite beam, has steel frame, in steel frame Rolling Production process, be entrenched in the wooden a tree, used in making timber for boats in the steel frame, described steel frame has base plate, two side plates, two opening edges are along plate, each opening edge along a plate side plate corresponding with it be connected as a single entity and with this side plate shape β in an angle, its technical scheme is the arc surface (arcwall face) that the base plate of above-mentioned steel frame is indent, have the groove that embeds in the wooden a tree, used in making timber for boats on two side plates respectively, described each opening edge is along a plate side plate formed angle 60 °≤β corresponding with it＜90 °.
In the technique scheme, described groove preferably lays respectively at the medium position of two side plates.Described each opening edge can be between 75 °～85 ° along a plate side plate formed angle β corresponding with it.
The utility model is in steel frame and the rolling chimeric process of wooden a tree, used in making timber for boats, and by base plate and the distortion of side plate indent, opening edge makes wooden a tree, used in making timber for boats produce distortion along button in the plate, thereby steel frame and wooden a tree, used in making timber for boats are closely linked, and has also improved the tight ness rating of wooden a tree, used in making timber for boats simultaneously.Its usefulness is: its base plate is the indent arcwall face, thereby makes base plate form two crest lines, and leveling is easy in the erection process at the scene; The groove of side plate is equivalent to two reinforcing ribs, thereby has improved rigidity, intensity, and is not yielding; Steel frame combines closely with wooden a tree, used in making timber for boats, has effectively avoided in use steel frame and wooden a tree, used in making timber for boats absciss layer phenomenon, thereby has improved the turnover access times.
