Abstract
The utility model discloses a reinforcement beam comprising a beam body, an anchor bearing plate, a reinforcing steel bar with threads at two ends, and a screw cap matched with the threads at the end parts of the reinforcing steel bar, wherein a full-length slot is formed at the bottom of the beam along the longitudinal direction; the reinforcing steel bar is implanted into the slot; two ends of the reinforcing steel bar pass through the anchor bearing plate arranged at the end of the beam; threads are processed at the end parts of the reinforcing steel bar. The stress of the reinforcing steel bar can be adjusted by screwing the screw cap according to the service condition. The problems that the existing reinforcement beam is complicated in construction technology, and single in used raw material, and the deformation of the beam and the stress of the reinforcing steel bar in the use procedure cannot be regulated and controlled are solved.
Description
Technical field
The utility model relates to wooden frame reinforcement technology, relates in particular to a kind of arrangement of reinforcement wooden frame.
Background technology
The wooden frame of present stage is strengthened technology and is mainly comprised configuration reinforcement, steel wire and configuration fibrous material aspect, is using on object, and existing achievement in research and technology are only applicable to common wooden frame, there is no to introduce the more high-strength material such as laminated wood, bamboo; In implementation process, existing form of reinforcement is also comparatively complicated, is inconvenient to be applied in Practical Project; In result of use, existing technology does not make the TERM DEFORMATION problem of wooden frame be well solved.
Utility model content
For solving current arrangement of reinforcement wooden frame complicated construction technique, in Practical Project, be difficult to be applied and the problem such as the TERM DEFORMATION of beam, the utility model provides a kind of arrangement of reinforcement wooden frame, and it is as follows that it addresses the above problem adopted technical scheme:
A kind of arrangement of reinforcement wooden frame, comprise beam body, be arranged on the threaded reinforcing bar in anchor plate, two ends at beam body two ends and with the supporting nut of the two ends screw thread of reinforcing bar, wherein, beam body is elongated at least one groove of offering longitudinally, the threaded reinforcing bar in described two ends is positioned in groove, the number of reinforcing bar is corresponding with the number of groove, reinforcing bar is through the anchor plate at beam body and beam body two ends, by reinforcing bar being fixed with the supporting nut of end reinforced screw thread, in the process of rotary nut, control the stretch value Δ L of reinforcing bar according to the anglec of rotation θ of nut, thereby change the stress intensity of reinforcing bar.
The beneficial effects of the utility model are:
1. easy construction, technique is simple.Can control reinforcement stresses by tightening end reinforced nut, without professional tensioning equipments such as hydraulic jack.
2. regulation and control are convenient, stressed reliable.In use can adjust reinforcement stresses size at any time, can effectively overcome the phenomenon that creep of wood increases wooden frame distortion.
3. can utilize fully wooden frame beam body and reinforcing bar intensity separately, save material.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and exemplary embodiment, the utility model is further elaborated.Should be appreciated that exemplary embodiment described herein is only in order to explain the utility model, and be not used in the restriction scope of application of the present utility model.
In conjunction with Fig. 1～Fig. 3, present embodiment is described.A kind of arrangement of reinforcement wooden frame of present embodiment comprises beam body 1, be arranged on the threaded reinforcing bar 3 in anchor plate 2, two ends at beam body two ends and with the supporting nut 4 of the two ends screw thread of reinforcing bar 3.Wherein, described beam body 1 is for example solid wood or laminated wood.
Further, referring to Fig. 4, beam body 1 is elongated at least one groove of offering longitudinally, and the threaded reinforcing bar 3 in two ends is positioned in groove, and the number of reinforcing bar 3 is corresponding with the number of groove.The two ends of reinforcing bar 3 are through the anchor plate 2 at beam body 1 and beam body two ends, by reinforcing bar 3 positions being fixed with the supporting nut 4 of end reinforced screw thread.Preferably, described at least one groove is opened in the bottom of beam body 1.
In rotary nut process, control the stretch value Δ L of reinforcing bar 3 according to the anglec of rotation θ of nut, thereby change the stress intensity of reinforcing bar 3.Preferably, for convenience of determining the anglec of rotation, nut 4 indicates scale.Wherein, there is corresponding relation in the STRESS VARIATION Δ σ of reinforcing bar stretch value Δ L, member length L and reinforcing bar:
Δσ=nE·ΔL/L
Wherein, n is correction factor, the modulus of elasticity that E is reinforcing bar, and described member length L is two length between nut 4.
Suppose that cap rotation causes that the elongation of reinforcing bar is Δ L for one week
0, the pass of cap rotation angle θ and reinforcing bar elongation is:
ΔL=ΔL
0θ/2π
The width of supposing beam body section is b, and depth of section is h, and useful cross section height is h
0, the area of reinforcement is A
s, beam body section end face stress f

Thus, control the stress intensity of reinforcing bar 3 by controlling the anglec of rotation of nut, in the use procedure of beam, suitably adjust the anglec of rotation of nut according to its deformation, improve the distortion of beam body by controlling the stress intensity of reinforcing bar 3.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
