Abstract
The utility model relates to a building structural member, in particular to a composite beam used in a concrete-wood combined structure house, which belongs to the technical field of building structural members. Key points of the composite beam are that: a wood beam is provided with a series of transverse grooves; steel member bars are vertically fixed in the grooves; a layer of concrete poured layer is covered on the wood beam and the grooves; and a tensile bar which is accordant with the longitudinal direction of the beam is embedded in the concrete poured layer. Compared with the conventional wood beam, due to the composite beam, the intensity and rigidity of the member can be enhanced, and the fire resistance is effectively improved; and compared with a concrete beam, the dead weight of the composite beam can be effectively reduced and the construction cost can be lowered.
Description
Technical field
The utility model relates to the compound beam in a kind of building structural member, particularly concrete-wooden combining structure house, belongs to the building structural member technical field.
Background technology
At present, what the house of vast rural area adopted is wooden frame, though traditional wooden frame cost is lower, and the poor performance of opposing fire, the timber supporting capacity is limited, is difficult to accomplish than large span; The structural beams of concrete slab is then more thick and heavy, from great, and the cost height, a lot of poverty-stricken areas are difficult to bear.
Summary of the invention
The purpose of this utility model provides a kind of steel concrete-clark beam, compare with traditional wooden frame, but reinforcement intensity, rigidity is effectively improved fireproof performance; Compare with concrete slab, can effectively reduce deadweight, reduce cost.
The purpose of this utility model is achieved in that and has a series of transverse concave grooves on wooden frame, groove floor vertical fixing steel rod elements, cover one deck concrete pouring layer on wooden frame and the groove thereof, also be embedded with tensile reinforcement in the concrete pouring layer with the vertical consistency of beam.
Transverse concave groove on the described wooden frame is a groove; groove depth is 1/3～2/5 of a wooden frame height; the length of groove is 1.5～2.5 times of width; steel rod elements fixedly enters 3/5～1/2 of wooden frame height; steel rod elements is partly with rough surface in the concrete pouring layer; the diameter of longitudinal tensile reinforcing bar is 12～18mm, and the concrete cover greater than 15mm is arranged between tensile reinforcement and wooden frame.
When described compound beam span was 6～10m, deck-siding was 25～50cm, and the deck-siding height is 30～60cm, and depth of groove is 1/3 of a wooden frame height, and the length of groove is 2 times of width, 6～8 of groove quantity, and the concrete pouring layer thickness is 80～120mm.Can adopt diameter at the fixing steel rod elements of wooden frame and concrete pouring layer is the bolt of the band spiral matsurface of 16mm.
The beneficial effects of the utility model are:
The comprehensive utilization timber compoment is conducted oneself with dignity low and characteristics that concrete component load-bearing power is high, and reinforcement intensity, rigidity are effectively improved fireproof performance, effectively reduce deadweight, reduce cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: concrete pouring layer 1, bolt 2, groove 3, wooden frame 4, tensile reinforcement 5.
The specific embodiment
In Fig. 1, the compound beam span is 6～10m, deck-siding is 25～50cm, the deck-siding height is 30～60cm, vertically have 6～8 grooves 3 along wooden frame 4, the degree of depth of groove 3 is 1/3 of wooden frame 4 height, the length of groove is 2 times of width, the 16mm bolt 2 that will have a spiral matsurface is screwed into the groove position of wooden frame 4 and fixes, cast concrete pouring layer 1 on wooden frame and groove thereof, concrete thickness is 80～120mm, and in concrete Φ 12～18mm tensile reinforcement 5 of the vertical consistency of embedding and beam, so just can manufacture concrete-clark beam.
