Technical field

The present invention relates to technical field of civil engineering more particularly to the fixing means and fixed device of a kind of flexural member.

Background technique

Currently, in building specification and civil engineering structure theory, for flexural member (usual fingerboard, plate or retaining wall Deng) both ends bearing state, generalling use following two mode is calculated, respectively hypothesis flexural member end be hinge Branch and the end for assuming flexural member are clamped mode.In above two mode, flexural member bears whole load, And the bearing state assumed once generates.

It based on this, is found in actual design and construction, is hinged using the both ends for assuming beam by taking single beam as an example When mode, Liang Man is that parabolically shape is distributed (such as Fig. 1 institute across the bending moment diagram under the action of uniformly distributed vertical load q (q > 0) Show), at this point, the both ends moment of flexure of beam is zero (i.e. moment of flexure at A, B two is zero), and span centre generates maximum moment M_c1=ql²/ 8, Therefore, the moment of flexure width difference of the both ends of beam and span centre is maximum Δ₁=ql²/8.And it uses and assumes that the both ends of beam are clamped side When formula, Liang Man is across (as shown in Figure 2) that the bending moment diagram under uniformly distributed vertical load q effect is also that parabolically shape is distributed, still, The both ends (i.e. in Fig. 2 at A, B two) of beam generate extreme value hogging moment M at this time_A=M_B=-ql²/ 12, span centre generates small size sagging moment M_c2 =ql²/ 24, the moment of flexure width difference Δ of both ends hogging moment and positive moment of span central point₂=ql²/24.Although this mode is compared to hypothesis beam Both ends be hinged moment of flexure width difference Δ₁=ql²/ 8 are reduced, but positive moment of span central point and both ends hogging moment also differ compared with Greatly.

Although it follows that it is understood that, flexural member (such as beam) both ends calculated using traditional theory and span centre There are this extremely uneven pessimums for positive hogging moment, but since current people are also constantly in inherency reason for this cognition Solution, and the habitual mode received and applicability is applied, in the structure so as to cause flexural member in actual design and construction Stress performance and economy are bad, possibly even occur erroneous judgement structure infeasible situation when serious.
