Description

Technical Field

[0001] The present invention relates to a component structure of a building floor slab, and in particular to a highly adaptable floor deck structure, which can serve as a construction basis for the building floor slab to facilitate rapid pouring construction of the building floor slab. Background Art

[0002] To effectively shorten the construction period of building floors, steel truss floor decks using metal plates as bottom formwork have begun to be used. Existing steel truss floor decks generally consist of a bottom formwork steel plate with web reinforcement fixedly connected to its surface. These web reinforcements are then fixed to corresponding upper and lower chords, forming a steel truss arranged side by side on the bottom formwork steel plate.

[0003] By completing the production of steel truss floor decks with metal plates as bottom formwork in the factory, the construction of the floor slabs can be completed on site by simple lifting, splicing and quantitative concrete pouring, which greatly shortens the construction period, reduces costs and improves construction efficiency. During the splicing process of existing steel truss floor decks, two adjacent bottom formwork steel plates are generally butted together by overlapping. The stability of the splicing joints is relatively weak, which not only makes it easy to leak concrete during pouring, but also makes it easy for vibration problems to cause stress concentration at the splicing joints of the two bottom formwork steel plates during subsequent use of the building floor slabs, which can cause cracks in the floor slabs and affect the service life of the building floor slabs.

[0004] Therefore, the research purpose of the present invention is to design a highly adaptable floor deck structure that can effectively improve the joint stability between the bottom formwork steel plates of two adjacent floor decks, and can form a vibration reduction function at the joint of the bottom formwork steel plates, thereby avoiding excessive leakage during concrete pouring and reducing the probability of cracking of the floor slab at the joint of the bottom formwork steel plates. Summary of the Invention

[0005] In response to the technical problems existing in the above-mentioned prior art, the present invention provides a highly adaptable floor deck structure, which can effectively solve the technical problems existing in the above-mentioned prior art.

[0006] The technical solution of the present invention is: A highly adaptable floor deck structure, comprising: A plurality of bottom formwork steel plates are arranged in a square shape, and a plurality of truss steel bars are arranged side by side on the bottom formwork steel plates. The truss steel bars respectively include a group of web steel bars fixed to the bottom formwork steel plates, and corresponding upper chord steel bars are respectively fixed between the upper ends of a group of web steel bars, and corresponding lower chord steel bars are respectively fixed to the bottom sides of the web steel bars; A multifunctional connection mechanism, wherein corresponding connection plates are fixed upward on both sides of the bottom mold steel plate, and corresponding arc-shaped plates are concavely provided on the upper ends of the connection plates. After two adjacent bottom mold steel plates are spliced side by side, the outer sides of the connection plates abut against each other, and the arc-shaped plates are spliced into an arc-shaped slot; the multifunctional connection mechanism includes a fixed rod fixedly abutting against the upper side of the arc-shaped slot, and limiting rods are fixed downwardly on both sides of the fixed rod through connecting members to clamp between the arc plate and the connection plate, and the fixed rod is hollow and fixedly filled with vibration-damping material; A plurality of support assemblies are fixedly installed at intervals between the limiting rod and the corresponding lower chord steel bars.

[0007] The cross section of the fixing rod is adapted to the arc-shaped slot, and the vibration-damping material is aluminum spherical damping particles.

[0008] The ends of the arc-shaped plates are respectively provided with corresponding clamping protrusions, one end of the limiting rod abuts against the inner side surface of the connecting plate, and the other end of the limiting rod abuts against the clamping protrusions.

[0009] The connecting plates are respectively hollowed out to form a plurality of corresponding through holes.

[0010] The support assembly includes a group of abutment joints arranged at intervals, and the opposite sides of the abutment joints are respectively provided with abutment grooves that are clamped on the limiting rod and the lower chord steel bar. A group of corresponding arc-shaped support rods are fixedly connected between the two sides of a group of the abutment joints in an outward convex arc shape, and a corresponding double-rotation screw is connected between the middle parts of a group of the arc-shaped support rods through a threaded connection. The double-rotation screw is used to shorten the distance between a group of the arc-shaped support rods, so that a group of the abutment joints are respectively moved outward and tightened and fixed between the corresponding limiting rod and the lower chord steel bar.

[0011] The limiting rods are fixedly connected with corresponding limiting shafts at positions corresponding to the abutting joints, and the abutting joints are tightly fixed to the limiting shafts.

[0012] A rubber C-shaped piece is fixedly connected to the abutting groove of the abutting joint, and corresponding baffles are respectively provided on the outer sides of both ends of the abutting groove. When the abutting joint is tightly fixed to the limiting shaft and the lower chord steel bar, the inner end of the rubber C-shaped piece is compressed and extruded forward to form an extrusion deformation. Under the limitation of the baffle, the outer sides of both ends of the rubber C-shaped piece are respectively squeezed and clamped onto the limiting shaft and the lower chord steel bar.

[0013] Several groups of strip-shaped protrusions are arranged side by side on the bottom formwork steel plate, and the web reinforcements respectively include a V-shaped portion fixed to the strip-shaped protrusions, and corresponding inverted V-shaped portions are integrally fixed upwardly and obliquely between two adjacent V-shaped portions. The lower chord reinforcements are respectively fixed to the junctions between the V-shaped portions and the inverted V-shaped portions, and the upper chord reinforcements are respectively fixed between the tops of the inverted V-shaped portions.

[0014] Corresponding support horizontal steel bars are fixedly welded between the ends of the lower chord steel bars, and the middle parts of the support horizontal steel bars are respectively fixed vertically upward with support vertical steel bars whose top ends are welded to the upper chord steel bars.

[0015] Corresponding connecting steel bars are transversely arranged between the upper chord steel bars, and the connecting steel bars are fixed to the upper chord steel bars by means of iron wire tying.

[0016] Advantages of the present invention: 1) The present invention first fixes connecting plates upward on both sides of the bottom formwork steel plate, and the upper ends of the connecting plates are respectively concavely provided with corresponding arc plates, so that after the two adjacent bottom formwork steel plates are spliced side by side, the outer sides of the connecting plates abut against each other, and the arc plates are spliced into an arc-shaped slot; then a multifunctional connecting mechanism is added, which includes a fixed rod fixedly abutted against the upper side of the arc-shaped slot, and the two sides of the fixed rod are fixed downwardly with limiting rods clamped between the arc plate and the connecting plate through connecting parts. After the bottom formwork steel plates of the two adjacent floor decking plates are spliced together, the fixed rod and the limiting rod are synchronously plugged into place by transverse plug-in, and then the support assembly is fixedly installed at intervals between the limiting rod and the corresponding lower chord steel bar to form a lift for the limiting rod, that is, the connecting plates on both sides of the bottom formwork steel plate are lifted upward, so that sufficient mutual abutment force is formed between the two adjacent bottom formwork steel plates. In this way, the joint stability between the bottom formwork steel plates of two adjacent floor decking plates can be effectively improved. In addition, the fixed rods are hollow and fixedly filled with vibration-damping materials, so that a vibration-damping function can be formed at the joints of the bottom formwork steel plates, thereby avoiding excessive leakage of concrete during pouring and reducing the probability of cracks forming on the floor slabs at the joints of the bottom formwork steel plates.

[0017] 2) The vibration-damping material fixedly loaded in the fixed rod of the present invention adopts aluminum spherical damping particles, which are relatively light in weight and have sufficient strength, thereby effectively ensuring the supporting rigidity of the fixed rod while being lightweight, thereby ensuring the practical effect of the present invention; and the ends of the arc-shaped plates of the present invention are respectively provided with corresponding snap-fitting protrusions, one end of the limiting rod abuts against the inner side surface of the connecting plate, and the other end abuts against the snap-fitting protrusion, thereby ensuring the limiting effect of the connecting plate and the arc-shaped plate, thereby further ensuring the practical effect of the present invention.

[0018] 3) The support assembly of the present invention includes a set of spaced abutment joints, each with an abutment groove on its opposite side that clamps onto the limit rod and the lower chord reinforcement. A corresponding set of arc-shaped support rods are fixedly connected in an outwardly convex arc shape between the two sides of each abutment joint. A corresponding double-rotation screw is threadedly connected between the middle portions of each set of arc-shaped support rods. The double-rotation screw shortens the spacing between the arc-shaped support rods, allowing each set of abutment joints to be moved outward and tightened between the corresponding limit rod and the lower chord reinforcement. This ensures that the support assembly can be easily assembled between the limit rod and the lower chord reinforcement, thereby helping to improve construction efficiency.

[0019] 4) The connecting plate of the present invention is hollowed out with a plurality of corresponding through holes to ensure that the concrete material after pouring can pass through the connecting plate, thereby overcoming the problem of insufficient integrity of the concrete material after pouring caused by the setting of the connecting plate.

[0020] 5) The hollow setting of the connecting plate, coupled with the load of the fixed rod and the limiting rod, can easily cause the connecting plate to collapse, especially during the concrete pouring process. To this end, the present invention further fixes a limiting shaft on the limiting rod, and fixes a rubber C-shaped member in the abutment groove of the abutment joint, and corresponding baffles are provided on the outer sides of both ends of the abutment groove. When the abutment joint is tightly fixed to the limiting shaft and the lower chord steel bar, the inner end of the rubber C-shaped member is compressed and deformed forward. Under the limitation of the baffle, the outer sides of both ends of the rubber C-shaped member are squeezed and clamped onto the limiting shaft and the lower chord steel bar to tighten the limiting shaft and the lower chord steel bar. In this way, the support assembly can be quickly assembled, and the stability of the connection between the support assembly and the limiting shaft and the lower chord steel bar can be ensured after the assembly is completed, thereby overcoming the collapse problem of the connecting plate caused by the hollow setting and load problem.

DETAILED DESCRIPTION

[0026] In order to facilitate understanding by those skilled in the art, the structure of the present invention is further described in detail with reference to the embodiments and the accompanying drawings: refer to Figure 1-4 , a highly adaptable floor deck structure, comprising: A plurality of bottom formwork steel plates 1 are arranged in a square shape. A plurality of truss steel bars 2 are arranged side by side on the bottom formwork steel plates 1. The truss steel bars 2 each include a group of web steel bars 201 fixed to the bottom formwork steel plates 1. A corresponding upper chord steel bar 202 is fixed between the upper ends of a group of web steel bars 201, and a corresponding lower chord steel bar 203 is fixed to the bottom side of each web steel bar 201. The multifunctional connecting mechanism 3 has corresponding connecting plates 101 fixed upward on both sides of the bottom mold steel plate 1, and the upper ends of the connecting plates 101 are respectively concavely provided with corresponding arc-shaped plates 102. After two adjacent bottom mold steel plates 1 are spliced side by side, the outer sides of the connecting plates 101 abut against each other, and the arc-shaped plates 102 are spliced into an arc-shaped slot. The multifunctional connecting mechanism 3 includes a fixing rod 301 fixedly abutting against the upper side of the arc-shaped slot. The two sides of the fixing rod 301 are fixed downwardly through the connecting member 4 to limit rods 302 clamped between the arc-shaped plate 102 and the connecting plate 101. The fixing rod 301 is hollow and fixedly filled with vibration-damping material 303. A plurality of support assemblies 5 are fixedly installed at intervals between the limiting rod 302 and the corresponding lower chord steel bars 203 .

[0027] After the bottom formwork steel plates 1 of two adjacent floor decks are spliced together, the present invention simultaneously inserts the fixing rod 301 and the limiting rod 302 into place by means of transverse plug-in, and then the support assembly 5 is fixedly installed between the limiting rod 302 and the corresponding lower chord steel bar 203 at intervals to lift the limiting rod 302, that is, to lift the connecting plates 101 on both sides of the bottom formwork steel plate 1 upward, thereby forming sufficient mutual contact force between the two adjacent bottom formwork steel plates 1. In this way, the splicing stability between the bottom formwork steel plates 1 of the two adjacent floor decks can be effectively improved. In addition, the fixing rod 301 is hollow and fixedly filled with vibration-damping material, so that a vibration-damping function can be formed at the splicing of the bottom formwork steel plates 1, thereby avoiding excessive leakage of concrete during pouring and reducing the probability of cracking of the floor slab at the splicing of the bottom formwork steel plates 1.

[0028] The cross section of the fixing rod 301 is adapted to the arc-shaped slot, and the vibration-damping material 303 is made of aluminum spherical damping particles.

[0029] The ends of the arc-shaped plates 102 are respectively provided with corresponding snap-fitting protrusions 6 . One end of the limiting rod 302 abuts against the inner side surface of the connecting plate 101 , and the other end of the limiting rod 302 abuts against the snap-fitting protrusions 6 .

[0030] The vibration-damping material 303 fixedly loaded in the fixing rod 301 of the present invention adopts aluminum spherical damping particles, which are relatively light in weight and have sufficient strength, so that the supporting rigidity of the fixing rod 301 can be effectively ensured under the premise of light weight, thereby ensuring the practical effect of the present invention; and the ends of the arc-shaped plate 102 of the present invention are respectively provided with corresponding snap-fitting protrusions 6, one end of the limiting rod 302 abuts against the inner side surface of the connecting plate 102, and the other end abuts against the snap-fitting protrusion 6, thereby ensuring the limiting effect of the connecting plate 101 and the arc-shaped plate 102, thereby further ensuring the practical effect of the present invention.

[0031] The connecting plate 101 is hollowed out with a plurality of corresponding through holes 7 to ensure that the concrete material after pouring can pass through the connecting plate 101, thereby overcoming the problem of insufficient integrity of the concrete material after pouring caused by the setting of the connecting plate 101.

[0032] The support assembly 5 includes a set of spaced abutment joints 501. The opposing sides of the abutment joints 501 are each provided with an abutment groove that is clamped onto the limiting rod 302 and the lower chord steel bar 203. A corresponding set of arc-shaped support rods 502 are fixedly connected in an outward convex arc shape between the two sides of the abutment joints 501. A corresponding double-rotation screw 503 is connected to the middle of the arc-shaped support rods 502 via a threaded connection. The double-rotation screw 503 shortens the spacing between the arc-shaped support rods 502, allowing the abutment joints 501 to be moved outward and tightened between the corresponding limiting rod 302 and the lower chord steel bar 203. This ensures that the support assembly 5 is conveniently assembled between the limiting rod 302 and the lower chord steel bar 203, thereby helping to improve construction efficiency.

[0033] The limiting rod 302 is fixedly connected to a corresponding limiting shaft 8 at a position corresponding to the abutting joint 501 , and the abutting joint 501 is tightly fixed to the limiting shaft 8 .

[0034] A rubber C-shaped part 9 is fixedly connected to the abutting groove of the abutting joint 501, and corresponding baffles 10 are respectively provided on the outer sides of both ends of the abutting groove. When the abutting joint 501 is tightly fixed to the limiting shaft 8 and the lower chord steel bar 203, the inner end of the rubber C-shaped part 9 is compressed and extruded forward to form an extrusion deformation. Under the limitation of the baffle 10, the outer sides of both ends of the rubber C-shaped part 9 are respectively squeezed and clamped onto the limiting shaft 8 and the lower chord steel bar 203.

[0035] Due to the hollow setting of the connecting plate 101 and the load of the fixed rod 301 and the limiting rod 302, the connecting plate 101 is prone to collapse, especially during the concrete pouring process. To this end, the present invention further fixes the limiting shaft 8 on the limiting rod 302, and fixes a rubber C-shaped member 9 in the abutment groove of the abutment joint 501, and a corresponding baffle 10 is provided on the outer side of both ends of the abutment groove. When the abutment joint 501 is tightly fixed to the limiting shaft 8 and the lower chord steel bar 203, the inner end of the rubber C-shaped member 9 is compressed and deformed forward. Under the limitation of the baffle 10, the outer sides of both ends of the rubber C-shaped member 9 are squeezed and clamped onto the limiting shaft 8 and the lower chord steel bar 203, so as to tighten the limiting shaft 8 and the lower chord steel bar 203. This can not only quickly realize the rapid assembly of the support component 5, but also ensure the stability of the connection between the support component 5 and the limiting shaft 8 and the lower chord steel bar 203 after the assembly is completed, thereby overcoming the collapse problem of the connecting plate 101 caused by the hollow setting and load-bearing problems of the connecting plate 101.

[0036] Several groups of strip-shaped protrusions 103 are arranged side by side on the bottom formwork steel plate 1, and the web reinforcement bars 201 respectively include V-shaped portions 2011 fixed to the strip-shaped protrusions 103, and corresponding inverted V-shaped portions 2012 are integrated and fixed upwardly between two adjacent V-shaped portions 2011. The lower chord reinforcement bars 203 are respectively fixed at the junction of the V-shaped portions 2011 and the inverted V-shaped portions 2012, and the upper chord reinforcement bars 202 are respectively fixed between the tops of the inverted V-shaped portions 2012.

[0037] The ends of the lower chord steel bars 203 are respectively fixedly welded with corresponding support horizontal steel bars 11, and the middle of the support horizontal steel bars 11 is respectively fixed vertically upward with support vertical steel bars 12 whose top ends are welded to the upper chord steel bars 202.

[0038] Corresponding connecting steel bars 13 are transversely arranged between the upper chord steel bars 202 , and the connecting steel bars 13 are fixed to the upper chord steel bars 202 by means of iron wire tying.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
