Effect of the present utility model is:
One, the muscle structure of hanging of the present utility model, by hanging muscle unit at frame beam and the setting of frame post intersection, realize the support to frame beam, in the limited operating space of reverse construction, the frame beam that can allow span be more than or equal to 8m only need reach 75% of design strength just can shift to an earlier date form removal, compares existing early stripping formwork system supporting way, and it must reach 100% at concrete strength just can carry out form removal afterwards, the utility model can guarantee, under the prerequisite of construction quality, to reach the object of reduction of erection time.
Two, the muscle structure of hanging of the present utility model, first pre-buried one end of hanging muscle two in frame beam, pre-buried anchoring piece in frame post, the one end of hanging muscle one is welded on anchoring piece, before stripping, by free end overlap joint the firm welding of hanging muscle one and hanging muscle two, realize the support to frame beam, for the early form removal of follow-up frame beam provides advantage.Above-mentioned hang muscle Structural Tectonics simple, draw materials easily, cost is low and easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing early-dismantling formwork system;
Fig. 2 is the structural representation of the utility model one embodiment;
Fig. 3 is the structural representation of anchoring piece in the utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the one the utility model proposes being hung to muscle structure is described in further detail.According to the following describes and claims, advantage of the present utility model and feature will be clearer.It should be noted that, accompanying drawing all adopts very the form of simplifying and all uses non-ratio accurately, only in order to convenient, the object of aid illustration the utility model embodiment lucidly.
Illustrate that in conjunction with Fig. 2 and Fig. 3 one of the present utility model hangs muscle structure, for form removal construction morning under contrary sequence method, frame beam 21 is supported on frame post 20.In the accompanying drawings, for specific direction relation, be provided with on demand frame post 20 axis directions are made as to the axial xyz rectangular coordinate system of y.The axial frame post 20 of y and the axial frame beam 21 of x intersect vertically, and hang muscle structure and are arranged at both intersections and are positioned at frame beam 21 tops.As shown in Figure 2, it comprises that at least one hangs muscle unit 10, and the one end of hanging muscle unit 10 is fixed on the sidewall of frame post 20, and the other end that hangs muscle unit 10 is embedded in the frame beam 21 being supported on frame post 20.Adopt the muscle structure of hanging of the present utility model, in reverse construction process, without the strong point is set, only the two ends of hanging muscle unit need be fixed in respectively in frame post 20 and frame beam 21, can realize the support to frame beam, operate simple and easy, in limited operating space, the frame beam that can allow span be more than or equal to 8m reach design strength 75% time, just can shift to an earlier date form removal, shortened the construction period.
Further illustrate the muscle structure of hanging of the present utility model in conjunction with Fig. 2, preferably hang muscle structure and can comprise two both sides of hanging 10, two of muscle unit and hanging muscle unit 10 and be symmetricly set in frame post 20 axis.Frame post 20 and frame beam 21 are stressed evenly, are more conducive to the stable of post and beam structure.Two are hung muscle unit 10 and are less than 1/3rd of frame beam 21 spans with the space D 1 of two intersection points of frame beam 21 respectively, are conducive to the bending resistance of frame beam 21.
Preferably, hang muscle unit 10 and have an angle α with frame beam 21, angle α is preferably 45 °, now, hangs muscle unit 10 vertical with destruction face, at this moment hangs muscle unit 10 and can better play the effect of shearing resistance, guarantees stablizing of frame beam 21 structures.
The muscle unit 10 that hangs of the present embodiment overlaps and is welded by hanging muscle 1 and hanging muscle 2 12, hang muscle 1 and be more than or equal to 10d with the overlap joint and the weld length that hang muscle 2 12, be connected firmly to guarantee to hang muscle 1 and hang muscle 2 12, above-mentioned d is the larger diameter (below repeating no more) that longitudinal stress hangs muscle.And hang muscle 1 and be arranged on stressed smaller part with the joint that hangs muscle 2 12.
When Specific construction, first the one end of hanging muscle 1 is welded on the anchoring piece 14 of reserving in frame post 20 sidewalls, the one end of hanging muscle 2 12 is embedded in frame beam 21 in advance, before stripping, muscle 1 and free end overlap joint the firm welding of hanging muscle 2 12 will be hung again, it is easy to operate, is not subject to the restriction in space, construction plant.
For improving the bonding strength that hangs muscle 2 12 and frame beam 21, as shown in Figure 2, hang the anchorage length D2 that muscle 2 12 gos deep in frame beam 21 and be more than or equal to 30d.Hang muscle 2 12 and axially extend a segment distance D3 away from the direction of y axle along x frame beam 21 is interior, distance B 3 is more than or equal to 15d.
As shown in Figure 3, anchoring piece 14 is made up of steel plate 14a and the some welderings nail 14b that are welded on steel plate 14a, and in conjunction with Fig. 2, weldering nail 14b is embedded in frame post 20, steel plate 14a with hang muscle 1 and be welded and fixed.Hang muscle 1 and be more than or equal to 10d with the weld length of steel plate 14a, guaranteed to hang muscle 1 and be connected with the reliable of anchoring piece 14.Wherein, the present embodiment light plate 14a adopts the steel plate that thickness is 20mm, is of a size of 350mm × 250mm(long × wide), weldering nail 14b is four Φ 16 reinforcing bars, point two rows are distributed in a side of steel plate 14a.Arranging of weldering nail 14b increased the frictional force of anchoring piece 14 with frame post 20, improved the bonding strength that hangs muscle 1 and frame post 20.
Illustrate and adopt early form removal of the frame beam work progress that hangs muscle structure of the present utility model in conjunction with Fig. 2:
First, the template of supporting frame beam 21 and frame post 20, in the interior pre-buried one end of hanging muscle 2 12 of frame beam 21, at the interior pre-buried anchoring piece 14 of frame post 20 and the one end of hanging muscle 1 is welded on anchoring piece 14, will hang muscle 1 and free end overlap joint the firm welding of hanging muscle 2 12, until the concrete strength of frame beam 21 and frame post 20 reach design strength 75% time, the template of removing frame beam 21 and frame post 20, frame beam 21 is supported on frame post 20 by hanging muscle unit 10, and then realizes form removal morning of frame beam 21.
The muscle structure of hanging of the present utility model, by arranging and hang muscle unit 10 with frame post 20 intersections at frame beam 21, realize the support to frame beam 21, in the limited operating space of reverse construction, the frame beam that can allow span be more than or equal to 8m only need reach 75% of design strength just can shift to an earlier date form removal, compares existing common components supporting way, and it must reach 100% at concrete strength just can carry out form removal afterwards, the utility model can guarantee, under the prerequisite of construction quality, to reach the object of reduction of erection time.
In addition, the muscle structure of hanging of the present utility model, first in the interior pre-buried one end of hanging muscle 2 12 of frame beam 21, at the interior pre-buried anchoring piece 14 of frame post 20, the one end of hanging muscle 1 is welded on anchoring piece 14, before stripping, by free end overlap joint the firm welding of hanging muscle 1 and hanging muscle 2 12, realize the support to frame beam 21, for the 21 early form removals of follow-up frame beam provide advantage.Above-mentioned hang muscle Structural Tectonics simple, draw materials easily, cost is low and easy to operate.
Foregoing description is only the description to the utility model preferred embodiment; the not any restriction to the utility model scope; any change, modification that the those of ordinary skill in the utility model field does according to above-mentioned disclosure, all belong to the protection domain of claims.
