Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, concretely to an overhead floor structure of floor support plate. BACKGROUND

[0002] With the development of the construction industry, the proportion of assembly type construction is increasing, and the assembly type ground construction system is also increasing. Dry ground is an important component module for assembly type decoration to achieve high quality and high quality. Overhead ground is a difficulty and key point in the assembly type construction technology system.

[0003] Most of the currently disclosed overhead ground structures are difficult to apply to large-size ceramic tile surface layers, and there is a lack of overhead ground structures that are stable and reliable, have reasonable structures, and are convenient to install.

[0004] As disclosed in Chinese patent CN222207081U, an overhead ground structure suitable for large-size ceramic tile surface layers is provided by setting a support structure on the building floor and a ground structure above the support structure. The ground structure includes calcium silicate board one, high-strength extruded board, calcium silicate board two, and ceramic tiles laid in turn above the support structure, forming an overhead ground structure suitable for large-size ceramic tile surface layers, having good stability and adjustability. By setting anchor bolts and micro-foaming glue connected between the anchor bolts and the building floor, the wire nut drainage hole, screw rod drainage hole, drainage notch, inner drainage groove, and bottom drainage groove of the anchor bolt are interconnected to form a complete drainage structure between the elastic rubber base, support screw, and bearing support wire nut. By filling micro-foaming glue, the connection stability between the components is enhanced, and the connection and fixation between the building floor are facilitated, thereby enhancing the stability of the support structure, the overall structure is stable, convenient and reliable to install, and has the characteristics of safety and applicability.

[0005] However, the lower end of a ceramic tile is usually supported and fixed by anchor bolts installed at the four corners, resulting in a lower support effect on the center part of the ceramic tile than on the four corners. If the ceramic tile is unevenly stressed, only the center position may crack over time under pressure.

[0006] Therefore, there is an urgent need to provide an overhead floor structure of floor support plate that can uniformly support the overhead floor. UTILITY MODEL CONTENTS

[0007] The utility model aims to provide an overhead floor structure of floor support plate to solve the problems raised in the background technology.

[0008] In order to achieve the above object, the utility model provides the following technical scheme: an overhead floor structure of a floor support plate, including lower dry -method ground plate and upper dry -method ground plate, the upper dry -method ground plate fixed connection is in the upper end of lower dry -method ground plate, the upper end of upper dry -method ground plate is daubed with adhesive layer, the upper end of adhesive layer is connected with ground finish layer, the lower end of lower dry -method ground plate is connected with anchor bolt structure, the outer end of anchor bolt structure is connected with auxiliary support mechanism.

[0009] The auxiliary support mechanism includes a connecting rod connected to the outer end of the anchor bolt structure, the inner left and right ends of the connecting rod are connected with first threaded rods, the upper end of the first threaded rod is welded with a rotating handle, the upper side of the connecting rod is fixedly connected with a sleeve at equal distances, the inner side of the sleeve is connected with a second threaded rod, and the upper end of the second threaded rod is fixedly connected with a rotating ring on the outer side.

[0010] Further improvement lies in that the anchor bolt structure includes a fixed base arranged at the lower end of the lower dry-method ground plate, the upper end of the fixed base is fixedly connected with a support screw rod, the outer side of the upper end of the support screw rod is threadedly connected with a nut, and the outer side of the nut is fixedly connected with a support ring at the middle position.

[0011] Further improvement lies in that the left and right ends inside the connecting rod are provided with vertical circular holes, the outer side of the support screw rod is slidably connected with the inner side of the circular hole, the left and right lower sides of the connecting rod abut against the upper side of the fixed base, and the connecting rod is staggeringly connected to the outer ends of the anchor bolt structures at the left and right ends below the lower dry-method ground plate.

[0012] Further improvement lies in that the inside of the connecting rod is provided with a vertical first threaded hole, the outer side of the first threaded rod is threadedly connected with the inner side of the first threaded hole, so that when the first threaded rod rotates in the first threaded hole by rotating the rotating handle, the first threaded rod can move relative to the connecting rod.

[0013] Further improvement lies in that the inner side of the sleeve is provided with an internal thread, and the outer side of the second threaded rod is threadedly connected with the inner side of the sleeve, so that when the second threaded rod rotates by rotating the rotating ring, the second threaded rod can move relative to the sleeve.

[0014] Further improvement lies in that the inside of the lower dry-method ground plate is provided with vertical second threaded holes at the four corners, the upper end of the outer side of the nut is threadedly connected with the inner side of the second threaded hole, and the upper side of the support ring abuts against the lower side of the lower dry-method ground plate, so that the lower dry-method ground plate can be supported to different heights above the building ground by rotating the support screw rod to move relative to the nut.

[0015] A further improvement is that the supporting screw and the fixed base have vertical drainage holes inside, and the fixed base has drainage holes around the drainage holes. This allows the expanding foam to be injected into the nut through the second threaded hole inside the dry floor panel, then into the drainage holes in the supporting screw and the fixed base, and then out through the drainage holes around the fixed base. During the flow process, the foam gradually solidifies, ultimately making the anchor bolt structure and the dry floor panel firmly fixed to the building floor.

[0016] In summary, this application discloses an elevated floor deck structure.

[0017] In this technical solution, after the dry floor panel is connected to the upper end of the anchor bolt structure, the second threaded rod is moved upward to the bottom side of the dry floor panel by rotating the rotating ring. This supports the middle part of the lower side of the dry floor panel, ensuring that the pressure that the floor surface layer above the anchor bolt structure can withstand is uniform and not easily cracked.

[0018] Furthermore, after the dry-laid floor panel and anchor bolt structure are connected and the height is adjusted, the anchor bolt structure is placed on the building floor. Then, expanding foam is injected into the nut through the second threaded hole inside the dry-laid floor panel, flows into the drainage holes in the support screw and the fixed base, and then flows out from the drainage holes around the inside of the fixed base. During the flow process, it gradually solidifies, and finally the anchor bolt structure and the dry-laid floor panel are firmly fixed to the building floor. Attached Figure Description
