The disclosure provides a kind of low clearance groove profile steel-concrete combination beam with enough bearing capacitys and span ability Structural form, can easily and efficiently it is prefabricated suitable for small across footpath highway bridge, foot bridge and city overhead pedestrian crossing low building The steel reinforced concrete combination beam of height.
In an optional embodiment of the disclosure, low clearance groove profile steel reinforced concrete combination beam can be mill work, root According to actual needs, sectional is prefabricated, lifts, is transported to construction ground, in-site installation after Cheng Liang.Low clearance groove profile steel reinforced concrete combination beam can With using having multiple T-steel beams of tooth form web to be welded into groove profile, the steel flange edges of 2 adjacent T-steel beams are mutually interconnected It connects.The tooth-shape structure outstanding being evenly arranged is as connector with combining in concrete slab on web.2 adjacent T Diaphragm plate can be set between section steel beam, play the role of support positioning and reinforce monolithic stability.
Specifically, as shown in Figure 1, low clearance groove profile steel reinforced concrete combination beam includes T-steel beam 1, diaphragm plate 2 and floorings 3.It is excellent Choosing, the quantity of T-steel beam 1 is 2, and one end of the web of each T-steel beam 1 is the tooth-shape structure being evenly arranged, such as Fig. 2 institute Show.After T-steel beam 1, diaphragm plate 2 and the combination installation of floorings 3, the tooth-shape structure on web is directly combined with floorings 3, i.e. group After closing installation, the tooth-shape structure on web is located at the inside of floorings 3.The tooth-shape structure on web is enabled to replace the welding such as shear connector T-steel beam 1 is connect by connector by the tooth-shape structure with floorings 3, and such structural form can be to a certain extent Reduce the welding sequence in work progress.Diaphragm plate 2 can be set between 2 adjacent T-steel beams 1, according to low clearance groove profile Each section of length of steel reinforced concrete combination beam is different, and 1 or more, such as 2 can be set in the quantity of diaphragm plate 2.2 adjacent T Section steel beam 1 and diaphragm plate 2 between the two collectively constitute groove profile girder steel.Groove profile girder steel is along bridge to configuration.Floorings 3 can be with Using Reinforced Concrete Materials, the configuration of 3 direction across bridge of floorings is vertical with the web of 2 T-steel beams 1 in the top of groove profile girder steel Connection.
In an optional embodiment of the disclosure, the preparation method of T-steel beam 1 is the following steps are included: selection is suitable 4 blanking of H profile steel of height, the web of H profile steel 4 is cut open from middle line with teeth outline, for example, the side for passing through plasma cut The web of H profile steel 4 is cut open from middle line with uniform teeth outline, obtains 2 T-steel beams 1, as shown in figure 3, each T-type by formula Web one end of girder steel 1 is equally distributed tooth-shape structure, and tooth form mutually staggers, and both can satisfy girder steel and concrete slab 3 requirement for height combined, in turn avoid the waste of steel.
In an optional embodiment of the disclosure, two 1 groups of T-steel beam for having tooth form web are welded together, As the support construction of low clearance groove profile steel reinforced concrete combination beam, diaphragm plate 2 can also be increased between two T-steel beams 1 to support Positioning, reinforces the overall stability of combination beam.Preferably, as shown in figure 4, configuring two between two sections of adjacent T-steel beams 1 The height of diaphragm plate 2, diaphragm plate 2 can be rationally arranged according to actual needs, what the bottom of each diaphragm plate 2 was welded together with group The steel edges of a wing of 2 adjacent T-steel beams 1 connects, and the two sides of the diaphragm plate 2 then web with 2 adjacent T-steel beams 1 respectively Connection.2 adjacent T-steel beams 1 and diaphragm plate 2 between the two group can be welded into groove profile girder steel jointly.Preferably, such as Shown in Fig. 5, using the double V groove butt weld connections of single side between the steel edge of a wing of two T-steel beams 1.Diaphragm plate 2 and T-steel beam 1 Between can also connect by welding.
In an optional embodiment of the disclosure, the preparation method of floorings 3 is the following steps are included: firstly, binding Reinforcing bar prepares steel reinforcement cage;Then, the bed die of floorings is installed based on groove profile girder steel;Spacer bar cage is lifted, by reinforcing bar cross Bridge is to being fixed on above groove profile girder steel, specifically, reinforcing bar direction across bridge to be fixed on to tooth-shape structure top and the tooth form of groove profile girder steel Between each tooth of structure;Limitation based on steel reinforcement cage and counterdie, casting concrete are prepared into steel bar concrete slab 3.Bridge After panel 3 forms, the maintenance in certain time limit is carried out to it according to requirement of engineering, and demoulding processing is carried out after maintenance expires.
In an optional embodiment of the disclosure, groove profile girder steel (i.e. T-steel beam 1 and diaphragm plate 2) can use non- Weather-proof Steel material.After simultaneously passed examination is completed in the welding of groove profile girder steel, after installation is combined with concrete slab 3, groove profile girder steel Exposed surface portion can carry out sanding, cleaning and japanning processing.And with the part groove profile that is connected inside concrete slab 3 The surface of girder steel (i.e. the tooth-shape structure part of T-steel beam), and the surface of part diaphragm plate 2 contacted with floorings 3, can be with Sanding and cleaning processing are only carried out in advance, safeguard procedures are taken to this part before other parts japanning, prevent coating dirty Dye.
In an optional embodiment of the disclosure, groove profile girder steel can be using the weather-proof Steel material for exempting from coating.In slot Section steel beam welding is completed and after passed examination, i.e. progress sanding and cleaning processing, is then combined installation with floorings 3.Or After person combines installation with concrete slab 3, then sanding and cleaning are carried out to the exposed surface portion of groove profile girder steel.Finally, will Groove profile girder steel and floorings 3 carry out watering and drying process repeatedly, for example, watering daily, dry at least three circulation, Continue at least 60 days.
The low clearance groove profile steel reinforced concrete combination beam of the disclosure can form two tools using common H profile steel blanking, cutting There is the T-steel beam of tooth-shape structure web, T-steel beam can eliminate welded connections, subtract directly in conjunction with concrete slab Lack welding sequence, and reduced the steel edge of a wing for being located at compressive region, saves material.What disclosed technique scheme needed Equipment is simple, and material loss is few, and concrete slab is combined into the beams of concrete of low clearance with welding groove section steel beam, can be in factory Interior segmentation is prefabricated, and prefabrication process is simple, lifts, is transported to job location, in-site installation after Cheng Liang, for the rapid construction of needs Urban Bridge, such as the steel reinforced concrete composite beam bridge of the low constructional heights such as small across footpath highway bridge or overhead pedestrian crossing has relatively strong Practicability and operability.
It will be understood by those of skill in the art that above embodiment is used for the purpose of clearly demonstrating the disclosure, and simultaneously Non- be defined to the scope of the present disclosure.For those skilled in the art, may be used also on the basis of disclosed above To make other variations or modification, and these variations or modification are still in the scope of the present disclosure.
