Description
Technical field
The utility model relates to prefabricated PC concrete T-shaped beam, specifically a kind of modified prefabricated PC coagulation
TuTLiang.
Background technique
Prefabricated PC concrete T-shaped beam is widely used as the load-carrying members of Short/Medium Span Bridge, mostly uses entirety greatly at present
Formula template replaces traditional Split form is prefabricated to form.Existing prefabricated PC concrete T-shaped beam includes several equideparture
The girder of row arrangement；The diaphragm of several equidistant parallels arrangement is equipped between two neighboring girder；Each diaphragm includes
Two precast sections and a Cast-in-Situ Segment, the head end of two precast sections are fixed with the both ends of Cast-in-Situ Segment respectively, the tail of two precast sections
End is fixed with the beam rib of two neighboring girder respectively.However in existing prefabricated PC concrete T-shaped beam, due to each tabula
The precast section of beam is all made of uniform thickness structure（There is no draw taper）, cause mixed using monoblock type template prefabricated prestressing
When solidifying soil T beam, on the one hand there is a problem of the difficult and time consuming length of demoulding, is on the other hand easy to draw bad tabula because knockout press is excessive
Beam makes diaphragm surface damage, thus on the one hand causes form cycling rate low, on the other hand leads to poor product quality.It is based on
This, it is necessary to the structure of existing prefabricated PC concrete T-shaped beam is improved, to solve to use the prefabricated dress of monoblock type template
Difficult and time consuming length is demoulded when with formula PC T beam, is easy to draw bad diaphragm because knockout press is excessive or make diaphragm
The problem of surface damage.
Summary of the invention
When the utility model is in order to solve using monoblock type template prefabricated prestressing concrete T-shaped beam demoulding it is difficult and
Time-consuming, be easy because knockout press is excessive draw bad diaphragm or make diaphragm surface damage the problem of, provide a kind of modified
Prefabricated PC concrete T-shaped beam.
The utility model adopts the following technical scheme that realization：
A kind of modified prefabricated PC concrete T-shaped beam, the girder including the arrangement of several equidistant parallels；It is two neighboring
The diaphragm of several equidistant parallels arrangement is equipped between girder；Each diaphragm includes that two precast sections and one are cast-in-place
Section, the head end of two precast sections fixes with the both ends of Cast-in-Situ Segment respectively, the tail end of two precast sections respectively with two neighboring girder
Beam rib fix；The thickness of the precast section of each diaphragm is gradually increased by head to tail；The tail end of two precast sections with it is adjacent
Rounded corner is equipped between the beam rib of two girders, and the radius of rounded corner is 5cm.
In use, each girder and each diaphragm play load-bearing effect jointly.
Compared with existing prefabricated PC concrete T-shaped beam, a kind of modified assembled described in the utility model is answered in advance
Power concrete T-shaped beam has the following advantages that：In the present invention, knot is thickened since the precast section of each diaphragm is all made of gradual change
Structure（With draw taper）, so that demoulding becomes convenient when using monoblock type template prefabricated prestressing concrete T-shaped beam
And it is time-consuming short, while avoiding and drawing bad diaphragm because knockout press is excessive or make diaphragm surface damage, thus on the one hand effectively
Form cycling rate is improved, product quality is on the other hand effectively increased.
The utility model is structurally reasonable, ingenious in design, efficiently solves using monoblock type template prefabricated prestressing
Difficult and time consuming length is demoulded when concrete T-shaped beam, is easy to draw bad diaphragm because knockout press is excessive or make diaphragm surface damage
Problem is suitable for Short/Medium Span Bridge.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In figure：The precast section of 1- diaphragm, the Cast-in-Situ Segment of 2- diaphragm, the beam rib of 3- girder, 4- rounded corner.
Specific embodiment
A kind of modified prefabricated PC concrete T-shaped beam, the girder including the arrangement of several equidistant parallels；It is two neighboring
The diaphragm of several equidistant parallels arrangement is equipped between girder；Each diaphragm includes that two precast sections 1 and one are cast-in-place
Section 2, both ends of the head end of two precast sections 1 respectively with Cast-in-Situ Segment 2 are fixed, the tail end of two precast sections 1 respectively with it is two neighboring
The beam rib 3 of girder is fixed；The thickness of the precast section 1 of each diaphragm is gradually increased by head to tail；The tail end of two precast sections 1
Rounded corner 4 is equipped between the beam rib 3 of two neighboring girder, and the radius of rounded corner 4 is 5cm.
When it is implemented, the length of the precast section 1 of each diaphragm is 75cm；The head of the precast section 1 of each diaphragm
Holding thickness is 18cm；The tail end thickness of the precast section 1 of each diaphragm is 28cm；The thickness of the Cast-in-Situ Segment 2 of each diaphragm
Degree is 18cm.
