Description
Technical field
The present invention relates to building element, is a kind of prestressing force overlapping board member.
Background technology
The overlapping board member that building field is commonly used has various structures, mainly according to different construction styles, different buildings
Purposes etc. needs to choose.The common deficiency of various overlapping board members is that integral rigidity is relatively low, and entire compression is low, is also easy to produce out
Split, span is small, deadweight is larger, amount of reinforcement is more, the particularly heavier-weight of bottom plate, thickness must reach 60 millimeter of -80 milli
Rice, causes the structural elements such as beam, post, wall, basis mutually to strain greatly, reduces floor height headroom, cast in place process when constructing at the scene
Complexity etc..
The content of the invention
It is an object of the present invention to provide one kind to organize space truss beam, and it can solve the problem that the deficiencies in the prior art.
The present invention to achieve the above object, is achieved through the following technical solutions：Including bottom plate, at least provided with a row on bottom plate
Steel bar girder, steel bar girder are made up of concrete rib, the first reinforcing bar and the second reinforcing bar, one end of the first reinforcing bar and the second reinforcing bar
One end is connected with concrete rib respectively, and the other end of the other end of the first reinforcing bar and the second reinforcing bar is connected with bottom plate respectively, and first
Reinforcing bar and the second reinforcing bar are parallel in length direction, the first reinforcing bar be bent into along its length several first tiltedly help with it is several second oblique
Help, the first oblique help between the second diagonal rib sets the first angle α1, the first angle α1For acute angle, the second reinforcing bar is bent along its length
Into several three tiltedly help with several 4th diagonal ribs, the second angle α is set between the 3rd diagonal rib and the 4th diagonal rib2, the second angle α2To be sharp
Angle, concrete rib are parallel to each other with bottom plate.Several first diagonal ribs, several second diagonal ribs, several 3rd diagonal ribs and several 4th oblique
Rib is parallel to each other in respective plane.First angle α1For 30 ° -70 °, the second angle α2For 30 ° -70 °.First angle α1With
Second angle α2For 40 ° -60 °.The cross-sectional area of concrete rib is rectangle, and length is 100 millimeters -250 millimeters, width 30
- 60 millimeters of millimeter.Multiple rows of steel bar girder is set on bottom plate, and the distance of the concrete rib centreline space of every two placing of reinforcements truss is 60
Centimetres -90 centimetres.The thickness of bottom plate is 25 millimeters -30 millimeters.Brace rod is set in bottom plate, and brace rod is through bottom plate both ends
Penetrate muscle.
The invention has the advantages that：It can once produce integral product on the production line of factory, overlap board member
Cross sectional moment of inertia is big, and bending resistance is strong, and rigidity is big, and stability is good, is not likely to produce cracking, adapts to large-span industrial building, workshop, storehouse
Demand is built in storehouse etc., the prestressing force vertical direction reinforcing bar being easy in through-flooring, is easy to set the pipeline such as water power in building.It is folded
Panel members local stability is good, and can freely cut as needed, because the integrally-built stability of the present invention is good, crushing resistance
Can be high, so bottom plate can be accomplished within 30 millimeters, in the case of the mitigation of width deadweight 50%, alleviate beam, post, wall,
The weight of basic component, and add the head room of construction level.The present invention also has overall structure firm, indeformable etc. excellent
First.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the present invention；Fig. 2 is Fig. 1 right side structural representation；Fig. 3 is Fig. 1 plan structure
Schematic diagram；Fig. 4 is Fig. 1 backsight structural representation.
Embodiment
Compareing accompanying drawing, the present invention will be further described.
3 be bottom plate in figure, and at least provided with a placing of reinforcement truss on bottom plate 3, steel bar girder is by concrete rib 1, the first reinforcing bar 7
Formed with the second reinforcing bar 2, one end of one end of the first reinforcing bar 7 and the second reinforcing bar 2 is connected with concrete rib 1 respectively, the first reinforcing bar 7
The other end and the other end of the second reinforcing bar 2 be connected respectively with bottom plate 3, the first reinforcing bar 7 and the second reinforcing bar 2 are put down in length direction
OK, the first reinforcing bar 7 is bent into several first and tiltedly helps 8 and several second tiltedly to help 9 along its length, and first tiltedly helps 8 and second diagonal rib 9
Between the first angle α is set1, the first angle α1For acute angle, the second reinforcing bar 2 is bent into several three and tiltedly helps 10 sums along its length
Individual 4th diagonal rib 11, the second angle α is set between the 3rd diagonal rib 10 and the 4th diagonal rib 112, the second angle α2For acute angle, concrete rib 1
It is parallel to each other with bottom plate 3.A plurality of brace rod 4 is set in the bottom plate 3 in said structure of the present invention, brace rod 4 is deformed bar,
Reinforcement 5 is set in concrete rib 1, to increase the compressive property of concrete rib 1.
First angle α of the present invention1For 30 ° -70 °, the second angle α2For 30 ° -70 °, this angle can be further
The support strength of several first diagonal bars 8 and several second diagonal bars 9 is improved, and improves several 3rd diagonal bars 10 and the several 4th simultaneously
The support strength of diagonal bar 11, and then increase the overall performance of overlapping board member.
Further preferential scheme of the invention is；First angle α1With the second angle α2For 40 ° -60 °, this angle can be entered
One step increases the support strength of the first diagonal bar 8, the second diagonal bar 9, the 3rd diagonal bar 10 and the 4th diagonal bar 11, further increases superimposed sheet
Resistance to overturning and compressive property.
