Description

Technical Field

[0001] The invention relates to the technical field of building floor structures, in particular to a floor structure that is easy to construct. Background Art

[0002] The traditional floor structure mainly includes a concrete floor and a steel skeleton embedded in the concrete floor. During the construction process: first, the formwork is built, and then the rolled steel bars are tied and arranged on the formwork according to the design to form a steel skeleton; then, concrete is poured; the formwork is removed after the concrete solidification strength reaches the design standard. Since the concrete pouring, rolling and tying of the steel skeleton need to be completed on the construction site, not only is the labor consumption relatively large, but the operation efficiency is low. In terms of construction efficiency, this will undoubtedly greatly increase the construction period of the project.

[0003] For this reason, prefabricated floor structures began to be put into use. With the continuous improvement of the construction technology of prefabricated floor structures, the existing prefabricated floor structures began to use a steel truss floor deck with concrete as the bottom form as the basis, and then further concrete was poured on the concrete bottom form of the steel truss floor deck. By completing the production of the steel truss floor deck with concrete as the bottom form in the factory, the construction of the floor structure can be completed by simple hoisting, splicing and a small amount of concrete pouring on site, thereby greatly shortening the construction period, reducing costs and improving construction efficiency. Since the concrete bottom form of the steel truss floor deck needs to be demolded conveniently during the pouring process in the factory, the two sides of the concrete bottom form of the steel truss floor deck are generally set in a vertical plane or an outward inclined plane.

[0004] When the two sides of the concrete bottom formwork of the steel truss floor decking are set in the shape of vertical planes, since its end faces cannot be completely flat, the splicing between the concrete bottom formworks of two adjacent steel truss floor deckings is relatively difficult. In many cases, it is necessary to grind the end faces of the concrete bottom formworks of the steel truss floor deckings. Moreover, after the concrete bottom formworks of two adjacent steel truss floor deckings are spliced, there are still many splicing seams at the splicing points, which require more subsequent filling operations. If the two sides of the concrete bottom formwork of the steel truss floor decking are set in the shape of outward slopes, the splicing operation is relatively easy. However, after the two adjacent steel truss floor deckings are spliced, there will be inverted V-shaped splicing grooves on the bottom surfaces. After the construction is completed and the formwork is removed, the corresponding splicing grooves still need to be filled, which is very troublesome.

[0005] Therefore, on the basis of ensuring the construction quality of the floor structure, the purpose of the present invention is to design a floor structure that is easy to construct, which can effectively, quickly and conveniently carry out splicing operations, facilitate the subsequent concrete pouring construction, and effectively and significantly reduce the amount of seam repair work of the floor structure after the construction is completed, thereby effectively improving the overall convenience of the floor structure construction. Summary of the invention

[0006] In view of the technical problems existing in the above-mentioned prior art, the present invention provides a floor structure that is easy to construct, and the floor structure that is easy to construct can effectively solve the technical problems existing in the above-mentioned prior art.

[0007] The technical solution of the present invention is:

[0008] A floor structure that is easy to construct, comprising:

[0009] A plurality of floor decks, each of which comprises a concrete bottom form, a steel bar truss with a top extending to the upper side of the concrete bottom form pre-embedded on the upper part of the concrete bottom form, and a plurality of the floor decks are laid side by side in abutment with each other;

[0010] A plurality of molding strips are arranged in a right-angled triangle shape in cross section, and corresponding slopes are arranged inwardly on both sides of the concrete bottom mold, and one side of the inclined surface of the molding strip is fitted and connected to the slope of the concrete bottom mold;

[0011] A connection mechanism is used to fix the molded rubber strip on the slope of the concrete bottom mold. The molded rubber strip is provided with a plurality of corresponding through holes arranged side by side. The connection mechanism comprises a rubber tube connected to the molded rubber strip at the inner end of the through hole, and corresponding fixing rods are respectively inserted in the rubber tubes; the fixing rods are driven to move outward, and after the inner end of the fixing rods leaves the rubber tubes, the molded rubber strips are removed, so that an upward V-shaped groove is formed at the connection of the concrete bottom molds of two adjacent floor decks after laying, and the side walls of the V-shaped groove are distributed with receiving holes formed after the rubber tubes are removed;

[0012] A concrete covering layer is laid on the upper side of the floor decking plate, the top surface of the concrete covering layer covers the upper side of the steel bar truss, and the bottom of the concrete covering layer is filled in the V-shaped groove and the receiving hole.

[0013] The inner end of the fixing rod is connected to the rubber tube by a threaded connection.

[0014] The outer end of the fixing rod is provided with a corresponding hexagonal groove. Before the floor deck is laid, the fixing rod is rotated by a corresponding hexagonal wrench to drive the fixing rod to leave the rubber tube.

[0015] The inner end of the fixing rod is fixedly connected with a magnet located inside the through hole of the molded rubber strip. After the floor decking is laid in place, the outer end faces of two adjacent molded rubber strips abut against each other, and the magnets on the corresponding fixing rods form magnetic attraction to drive the fixing rod to move outward.

[0016] The outer end of the through hole of the molded rubber strip is integrally formed with an annular limiting convex edge for blocking the magnet part.

[0017] The rubber tube is integrally formed and connected to the molded rubber strip, and the diameter of the rubber tube is gradually reduced from the connection between the rubber tube and the molded rubber strip outward.

[0018] The top surface of the molded rubber strip is provided with a plurality of inclined pulling holes at intervals, and the molded rubber strip can be removed by cooperating a pull rod provided with a hook with the inclined pulling holes.

[0019] The top surface of the molded rubber strip is provided with a plurality of corresponding threaded holes at intervals, and the molded rubber strip can be disassembled by cooperating a rod with external threads at the end thereof with the threaded holes.

[0020] The steel bar truss comprises a plurality of supporting steel bars arranged side by side, wherein the supporting steel bars are arranged in an inverted V shape, the bottom of the supporting steel bars are pre-embedded and installed on the upper part of the concrete bottom formwork, and corresponding connecting steel bars are fixedly connected to both sides and the top of the plurality of supporting steel bars.

[0021] Between two adjacent supporting steel bars in the same row of supporting steel bars, one is arranged to be inclined forward, and the other is arranged to be inclined backward.

[0022] Advantages of the present invention:

[0023] 1) The present invention uses a molding strip with a right-angled triangle cross section to enable the floor deck to be demoulded smoothly and conveniently after casting, and can make the two sides of the floor deck after casting to be inclined inwards, so as to facilitate subsequent use. Under the action of the connecting mechanism, the molding strip can be effectively and stably fixed on both sides of the demoulding floor deck, so that the molding strip can effectively form a buffer support for both sides of the floor deck, so as to ensure that it does not cause excessive bumps and other problems during transportation, hoisting and splicing.

[0024] 2) The connection mechanism of the present invention includes a rubber tube connected to the inner end of the through hole of the molded rubber strip, and corresponding fixing rods are respectively inserted in the rubber tube, and the fixing rods provide support for the rubber tube. After the concrete bottom mold is poured, the rubber tube is fixedly embedded in the concrete bottom mold, thereby effectively and stably fixing the molded rubber strip on both sides of the concrete bottom mold after demolding; after the splicing of the floor decking is completed, the fixing rod is driven to move outward, and after the inner end of the fixing rod leaves the rubber tube, the rubber tube is set in a hollow state. In addition, it itself is a flexible and deformable material piece. In this way, during the disassembly process of the molded rubber strip, the rubber tube can be simultaneously torn off the concrete bottom mold, so that an upward V-shaped groove is formed at the connection between the concrete bottom molds of two adjacent floor deckings, and the side walls of the V-shaped groove are distributed with accommodating holes formed after the rubber tube is disassembled; subsequently, the concrete covering layer can be directly poured in place.

[0025] Thereby, on the basis of ensuring the construction quality of the floor structure, the splicing operation can be carried out effectively, quickly and conveniently, and the subsequent concrete pouring construction can be facilitated. The amount of seam filling work of the floor structure after the construction is completed can be effectively and significantly reduced, thereby effectively improving the overall convenience of the floor structure construction.

[0026] 3) The inner end of the fixing rod of the present invention is fixedly connected to a magnet located on the inner side of the through hole of the molded rubber strip. After the floor decking is laid in place, the outer end faces of two adjacent molded rubber strips abut against each other, and the magnets on the corresponding fixing rods form a magnetic attraction force with each other to automatically drive the fixing rod to move outward, thereby further improving the convenience of the construction operation of the present invention.

[0027] 4) The outer end of the through hole of the molded rubber strip of the present invention is integrally formed with an annular limiting convex edge for forming a blocking position for the magnet member to prevent the fixing rod from being driven into the through hole of another molded rubber strip by the adsorption force, thereby ensuring the practical effect of the present invention.

[0028] 5) Between two adjacent supporting steel bars in the same row of supporting steel bars of the present invention, one is tilted forward and the other is tilted backward, so as to improve the bonding between the supporting steel bars and the concrete covering layer, thereby improving the overall structural stability of the present invention.
