Abstract
The invention relates to a floor system in the technical field of buildings, in particular to a concrete composite beam floor system and a pouring method thereof. The composite beam floor system comprises concrete and beams fixedly connected with the concrete, wherein each beam is inverted T-shaped; the top part of each beam is embedded inside the concrete; and steel reinforcement positioning grooves and/or pin-key holes are uniformly distributed at the upper end of each beam, which is embedded in the interior of the concrete. The pouring method comprises the following steps: laying a composite member positioning formwork, and installing the beams with the steel reinforcement positioning grooves on the formwork so that the steel reinforcement positioning grooves of the beams can be completely embedded inside the concrete after pouring; then laying a concrete plate bottom formwork; placing steel reinforcements in order inside the steel reinforcement positioning grooves and binding for fixation; and finally pouring concrete and removing formworks after the concrete is completely cured. In the invention, the height of the concrete layer is reduced and the space between the beams is increased, so that the building space is saved, the storey height of the building is reduced and the number of construction procedures is reduced.
Description
Technical field:
The present invention relates to the superstructure in the technical field of buildings, especially a kind of concrete combination beam superstructure and casting method thereof.
Background technology:
In building trade, the moulding of superstructure mainly contains following several mode at present:
1. cast in situs.Earlier with steel form or wooden form group mould, fluid concrete moulding again.The superstructure that adopts this method to build up has good whole and continuity, and easy construction, the anti-seismic performance height, but superstructure from great, spatial extent is little.
2. the pin-connected panel floor promptly builds superstructure with prefabricated hollow floor.Adopt the precast concrete cassette ceiling, can alleviate the weight of superstructure significantly.But the superstructure that uses the precast concrete cassette ceiling to build, and other pin-connected panel superstructures, overall performance is poor, particularly is easy to generate slight crack along the cassette ceiling edge joint position.And the supporting capacity of pin-connected panel superstructure and shock resistance, the superstructure and the same spatial extent that are lower than the monobloc cast moulding are little.
3. the forming method that combines of prefabricated units and cast-in-place member.The method can effectively be improved the shortcoming of pin-connected panel floor, is prefabricated units but adopt the floor structure face more, and beam is the method for cast-in-place member.The building central sill is a concrete, and shortcoming is that volume is big, and from great, spatial extent is little, and only is fit to the superstructure of the regular shape in plane, and its versatility is poor.
Above-mentioned several method all has many weak points, very is necessary to invent a kind of novel superstructure and satisfies existing demand.
Summary of the invention:
Deficiency at prior art exists the invention provides a kind of shock resistance that can improve whole building, increases the superstructure supporting capacity simultaneously, realizes the novel superstructure and the casting method thereof of bigger spatial extent.
The present invention realizes by following technical measures: a kind of concrete combination beam superstructure, comprise concrete and the beam of fixedlying connected with concrete, and described beam is an inverted T-shaped, and its top embeds in the concrete, and the upper end that embeds the beam of concrete inside is evenly equipped with reinforcing bar locating slot and/or pin key hole.
One angle α is arranged, adjacent reinforcing bar locating slot edge center line symmetry between the two between the top edge of described reinforcing bar locating slot and beam.Can make reinforcing steel bar bear balance at the bottom of the floor, improve the superstructure overall performance.
Be easy construction, the top edge angle α of described reinforcing bar locating slot and beam is 90 °.
Be the intensity of stiffening girder, the side of described beam is provided with stiffening rib.
Be the intensity of convenient processing and effective reinforcement, described stiffening rib is a plate rib.
In order to imitate the interlock that improves beam and concrete, described pin key is installed with reinforcing bar and/or pin key in the hole.
Described beam is made by metal, fiber, plastics or resin, and the material ranges of taking is wide.
β at an angle to each other between the described adjacent beams, and 0 °≤β＜180 ° make the compound mode variation of building roof beam, can build the superstructure of multiple shape.
Described Liang Jiaochalianjiechu adopts welding or bolt to be connected and fixed.
Narration by such scheme is learnt, owing to adopted beam to be partially submerged into the interior form of structure of concrete, has reduced the thickness of superstructure, and can give full play of the tensile property of beam, increases the interlock ability of beam and concrete; Reinforcing bar layout simultaneously forms steel mesh reinforcement in the reinforcing bar locating slot, beam and steel mesh reinforcement fuse, and have increased considerably the adhesive ability of beam on concrete.The both sides of beam are provided with stiffening rib, and the structural strength of stiffening girder has improved the integrated carrying ability of superstructure.
In order effectively to realize above-mentioned beneficial effect, the present invention also provides a kind of casting method that is used to realize above-mentioned concrete combination beam superstructure, comprises the steps:
(a) set up composite member locating template and beam, make the top edge of template be positioned at the below of reinforcing bar locating slot;
(b) set up the concrete slab soffit formwork;
(c) reinforcing bar is put into the reinforcing bar locating slot, and colligation is fixed into mesh skeleton;
(d) concreting is treated to remove template after concrete condenses firmly fully.
By as can be seen above-mentioned, casting method of the present invention is simple to operation, and the concrete combination beam superstructure of building out can improve the shock resistance of whole building, has increased the supporting capacity of superstructure again, can fully realize the beneficial effect of its aforementioned superstructure.
Superstructure among the present invention has than high bearing capacity, has compared with prior art alleviated structural weight per square meter significantly simultaneously, can realize bigger spatial extent.Beneficial effect of the present invention also has, the combination free of beam, and no fixed form can be built and be formed the superstructure that various lattices are formed multiple profile.In the present invention, coagulate layer thickness is little, and clearance spaces is arranged between the adjacent beams, can be building finishing and saves a large amount of installing spaces, saves the floor floor height.
