Abstract
The utility model relates to a prestressed hollow slab beam hinge joint connecting part which aims at providing a prestressed hollow slab beam hinge joint connecting part to enhance lateral linkage between slab beams and replace the traditional slab beam connecting steel bar. The utility model has the objective technical scheme that the prestressed hollow slab beam hinge joint connecting part is a long steel slab with a plurality of through holes.
Description
Technical field
The invention belongs to civil engineering bridge field, be specifically related to be used to prevent and treat the prestressed hollow slab beam hinge seam linkage of prestressed hollow slab beam bottom slab crack infiltration disease.
Background technology
At present in the bridge construction field, prestressed hollow slab beam bridge hinge seam quality has fundamental influence for the life-span of whole bridge, and infiltration appears in the seam of the hinge between prestressed hollow slab beam beam body, to analyse disease such as white very general.Think that at present its basic reason is a plate-girder hinge seam concrete cracking.Lateral ties between the plate-girder are destroyed.These disease forms may it reduce the supporting capacity of bridges and culverts, make the main supporting member in top be in very disadvantageous stress, quickened the development of bridges and culverts superstructure disease, acquiring a certain degree, it is progressively loose and come off that hinge seam concrete will take place, have influence on the normal operation of highway, cause serious hidden danger to safe driving.This also is the subject matter that long-term puzzlement pipe is supported unit and design, unit in charge of construction.
Therefore, study a kind of simple and effective and practical hinge seam connector the common disease of hinge seam is prevented and treated, the assurance of prestressed hollow slab beam bridge quality is had significance.
Summary of the invention
In occurring the stressed bridge of veneer, the crushed situation of precast hollow slab top board but seldom takes place.This illustrates hinge seam position at least in the design far below top board of the safety stock of design aspect, and the structure of hinge seam is reasonable inadequately.Particularly pre-buried connecting reinforcement tension and the shear resistance of two curb girder bodies is on the weak side in the hinge seam, and the colligation difficulty causes and is difficult between plate-girder effectively that connection is a major reason between reinforcing bar.From this angle, there are problems in pre-buried connecting reinforcement as a kind of connector.
The purpose of this utility model is to overcome the defective of prior art, and a kind of lateral ties that can strengthen between plate-girder are provided, to replace the prestressed hollow slab beam hinge seam connector of traditional plate-girder bracing reinforcement.
The purpose of this utility model technical scheme is, prestressed hollow slab beam hinge seam connector, and described connector is the long steel plate that has some perforation.
The essence of the described prestressed hollow slab beam hinge seam connector long steel plate of boring a hole exactly, requirement according to conditions such as load sizes, can wear reinforcing bar in the steel plate hole, also can not wear reinforcing bar, it and concrete binding are better, and its shear strength depends primarily on the shear strength of steel plate between hole inner concrete shear strength and hole, and the concrete in the hole and reinforcing bar prevent the effect that separates between connecting elements in addition, therefore not only possess the ability that strong opposing is sheared, also can resist pulling force effectively.In addition, described connector is installed also more convenient, cheap.
As further improvement of the utility model, described connector also comprises a pre-embedded steel slab, and the long steel plate of described perforation is vertically connected on the pre-embedded steel slab horizontal plane.When casting prestressed hollow slab beam in the fix usefulness of connector of beam side pre-embedded steel slab.
The beneficial effects of the utility model are, traditional prestressed hollow slab beam hinge seam structure design concept thinks that the hinge seam only is subjected to the vertical shear effect, and be subjected to the effect of horizontal direction lateral pull not cause enough attention to it, therefore the contact structure to hinge seam place does not carry out reasonable Arrangement, is difficult to the effect of cutting of drawing of synergy opposing to the hinge seam.The advantage of the utility model connector is not only have very strong anti-shear ability, aspect the lateral pull of resisting between plate-girder good performance is being arranged also.
Description of drawings
Fig. 1 is the utility model embodiment 1 structural representation
Fig. 2 is that the utility model embodiment 1 is installed in the structural representation on the prestressed hollow slab beam
The specific embodiment
Be described further below in conjunction with embodiment and accompanying drawing.
As shown in Figure 1, prestressed hollow slab beam hinge seam connector 1 comprises the long steel plate 2 and the pre-embedded steel slab 3 that have some perforation 5, and long steel plate 2 vertically is connected with pre-embedded steel slab 3 planes.
As shown in Figure 2, when casting prestressed hollow slab beam 4, the beam sidepiece be provided with pre-embedded steel slab 3 fix the perforation long steel plate 2 usefulness, treat on pre-embedded steel slab 3 horizontal planes, to weld steel plate 2 with holes after the demoulding, promptly form prestressed hollow slab beam hinge seam connector 1, utilize the stronger tension of connector cut ability and with the part measure of the good collaboration capabilities of concrete as control hinge seam disease, can save the trouble of equalizing connecting reinforcement and carrying out colligation simultaneously.
Claims (2)
1. prestressed hollow slab beam hinge seam connector is characterized in that described connector is the long steel plate that has some perforation.
2. prestressed hollow slab beam hinge seam connector according to claim 1 is characterized in that described connector also comprises a pre-embedded steel slab, and the long steel plate of described perforation is vertically connected on the pre-embedded steel slab horizontal plane.
