Description

Non-metallic bottom plate integrated floor carrier plate with steel bars and corresponding floor structure

Technical Field

The utility model relates to a non-metallic bottom plate integrated floor support plate with reinforcing steel bars and a floor structure (or floor layer structure) adopting the floor support plate.

Background

The bottom die of the floor structure adopts the disassembly-free template, so that the process can be simplified to a great extent, the production efficiency is improved, and the production cost is reduced. At present, steel bars of the floor support plate often adopt a steel bar truss or a similar steel bar frame structure, the steel bar truss consists of an upper chord bar, a lower chord bar and web bars for connecting the upper chord bar and the lower chord bar, and the lower chord bar is fixedly connected to the disassembly-free template through a connecting piece to form an integrated structure, so that the upper chord bar can be utilized for hoisting, storage and transportation and field assembly are convenient. For example, chinese patent document CN218233947U discloses a disassembly-free bottom die truss floor deck, comprising: the bottom die is a flat plate with preset thickness; the trusses are parallel to each other and are arranged on the bottom die at preset intervals, and the feet of the trusses are embedded at the position 3-10 mm away from the lower bottom surface of the bottom die, so that the trusses are firmly fixed on the bottom die. Chinese patent document CN218405979U discloses an assembled disassembly-free support plate comprising: the high-strength fiber cement pressure plate, one side of high-strength fiber cement pressure plate is provided with the light gauge steel, one side of light gauge steel is provided with the metal connection buckle, one side of metal connection buckle is provided with the turn-knob, fixes the truss reinforcing bar through setting up light gauge steel and metal connection buckle, fixes truss reinforcing bar and high-strength fiber cement pressure plate together, realizes that overall stability is strong, is convenient for transport and installation. The Chinese patent document CN113323216A discloses a support-free laminated slab and a construction method thereof, wherein the laminated slab comprises a steel bar truss, a detachment-free template and a support keel, the steel bar truss comprises an upper chord rib, a lower chord rib and web ribs connected between the upper chord rib and the lower chord rib in a wave mode, the support keel is fixedly connected to the bottom surface of the lower chord rib and the upper surface of the detachment-free template, a hoisting frame is fixedly connected to the upper chord rib and the support keel, the laminated slab adopts a steel bar truss, a galvanized steel keel and a reinforced fiber cement plate/calcium silicate plate, a support frame body reaches a 'point' support through the steel bar truss, the steel bar truss and the galvanized steel keel are fixed through dovetail nails, and an integral assembly component is formed through welding connection.

These prior art techniques have various characteristics and are respectively suitable for the respective occasions. However, there are still some common limitations or drawbacks, firstly that the web bars have a relatively high mass in the steel bar truss, but do not substantially contribute to the tensile/bending resistance of the floor slab structure in all directions, resulting in unnecessary material waste, and at the same time, unnecessarily increasing the weight of the floor slab, and secondly that although the upper and lower chord bars in the steel bar truss can play a role of a certain tensile bar, the steel bar layout, particularly the layout of the upper steel bars, is still required according to the reinforcement requirement of the floor slab, and at least in part of application scenarios, the upper chord bars cannot play a role sufficiently.

Preferably, two ends of the longitudinal (longitudinal or long-side direction of the floor support plate) steel bars on the steel bar net sheet are exposed outside (extend to) two ends of the bottom plate, and can be used as tension bars of the floor structure.

Further, the longitudinal bars on the reinforcing mesh are preferably located below the transverse bars (transverse or short side direction of the floor support plate).

Preferably, the steel bars connected (clamped) with the steel bar connecting pieces on the steel bar net sheet are longitudinal steel bars.

Further, the reinforcing bars connected (clamped) with the reinforcing bar connectors at least comprise longitudinal reinforcing bars positioned at two lateral sides.

Preferably, the bottom plate is provided with one or more rows of hanging bar supports extending longitudinally, and the tops of the hanging bar supports are provided with hanging bar connecting structures. According to actual needs, a hanging bar bracket is not required to be arranged on the bottom plate.

Further, two hanging bar brackets are included in either row of hanging bar brackets, which are respectively located at two longitudinal sides (with the longitudinal middle as a boundary, respectively located at two sides of the boundary and preferably located at positions near the two ends).

Further, one hanging bar is inserted into one row of hanging bar supports (only one row of hanging bar supports), or one hanging bar is inserted into each of the plurality of rows of hanging bar supports.

The hanging bar connecting structure may be a sleeve structure (sleeve-like structure) allowing the hanging bar to pass through.

Preferably, the vertical middle parts of the cylinder walls at the two sides of the sleeve structure are provided with strength weakening structures to form weak parts, and the vertical heights of the strength weakening structures at the two sides of the same sleeve structure are consistent.

For example, the two side cylinder walls of the sleeve structure on the hanging bar support are provided with a plurality of vertical long through holes, the vertical long through holes on the same side cylinder wall are distributed at equal intervals in the axial direction of the sleeve structure, and the vertical long through holes on the two sides of the same sleeve structure are symmetrically arranged.

The height of the hanging bar bracket fixedly connected in the structural layer meets the requirement. For example, should be below the level of the upper surface of the structural layer, and should not interfere with the placement of upper rebar or other necessary structures within the structural layer. When the hanging bar support is too high, a portion may be removed from the upper portion thereof, whereby the hanging bar support consolidated in the structural layer is the remaining portion after a portion is removed from the upper portion of the complete hanging bar support.

For example, in the case where the hanging bar connection structure is a sleeve structure allowing the hanging bar to pass through and the vertical middle portions of the wall of both sides of the sleeve structure are provided with strength weakening structures, the sleeve structure may be broken first in such a manner that the sleeve structure is broken from the middle portion of the side wall, and then the hanging bar may be taken out. Thus, the hanger bar bracket remaining on the bottom plate (or, alternatively, the hanger bar bracket consolidated in the structural layer) is in a state after the sleeve structure is broken from the middle of the sidewall (if not further cut).

In general, an upper layer of reinforcing steel bars can be further arranged in a cast-in-place concrete structural layer (or a cast-in-place reinforced concrete structural layer or simply a structural layer). According to actual needs, the upper layer of reinforcing steel bars can be omitted.

Further, the upper layer steel bar in the cast-in-situ concrete layer is composed of an upper layer steel bar net piece fixedly arranged above the steel bar net piece.

Preferably, the splicing mode of the floor support plates is that the floor support plates are arranged adjacently (connected) in sequence along the long span direction of the floor, and the long side direction of the floor support plates is along the short span direction of the floor.

The beneficial effects of the utility model are as follows: because the reinforcing mesh is arranged above the bottom plate and is composed of longitudinal reinforcing bars and transverse reinforcing bars which are mutually and fixedly connected together, the materials and the structures (distribution mode) of the reinforcing bars are selected according to/meet the requirements of the materials and the structures of the lower reinforcing bars of the floor structure (floor slab), the distance between the reinforcing mesh and the bottom plate is according to/meet the requirements of the distance between the lower reinforcing bars and the dismantling-free templates in the floor structure, and after the floor structure is built, the reinforcing mesh forms the lower reinforcing bars in the floor structure, so that the field layout of the lower reinforcing bars is omitted; because the bottom plate adopts a nonmetallic bottom plate, the bottom plate can be used as a disassembly-free bottom die for building structure concrete pouring, in particular to a bottom plate which can be used as a building plate of a direct ceiling without arranging a decorative plate on the ceiling; due to the arrangement of the hanging bar, the hanging bar can be hung, and after being installed in place on site, the hanging bar is taken down for repeated use, so that the steel waste is avoided; the lifting bar bracket (the top surface supporting height of the rest part after fracture) can be adapted to the height of an upper layer of steel bars (or steel bar meshes), after the lifting bar is taken down, the upper layer of steel bars (or steel bar meshes) can be arranged on the basis of the lifting bar bracket, meanwhile, the upper layer of steel bars can be directly supported on the lifting bar bracket by adopting the steel bar meshes, so that the field setting of the upper layer of steel bars is further facilitated, the steel bars for supporting the upper layer of steel bars are saved, and the steel consumption is further reduced; because a plurality of vertical long through holes are formed in the side wall of the sleeve structure of the hanging bar support, when the top or the side wall of the sleeve structure is subjected to larger external force (e.g. knocking by a hammer), the sleeve structure breaks at the side wall of the sleeve due to the fact that the vertical long through holes and other structures weaken the strength of the position, and therefore the hanging bar can be directly taken down, the hanging bar support below the broken position of the side wall of the sleeve structure is reserved on the bottom plate and can be used as a support/foundation for arranging/binding upper-layer reinforcing steel meshes.

The floor carrier plate has the advantages of simple preparation process, short production period, low cost and convenient site construction, and the formed floor has texture and texture conforming to the habit of people, is convenient to decorate, and can be used for cast-in-situ reinforced concrete floor engineering in any structural system.

When building construction, the non-metal floor integrated floor support plate with the steel bars (or the floor plate of the floor support plate) is used as a permanent template of the bottom die, a cast-in-situ concrete layer is arranged on the permanent template, and the steel bar net sheet is fixedly arranged in the cast-in-situ concrete layer (reinforced concrete structure layer) to form lower steel bars in the structure layer. According to the actual needs, the upper layer steel bars and other steel bars (if provided) are arranged and bound before the concrete is poured.

The floor support plate can be prepared into products by adopting automatic equipment on a factory production line.

A plurality of hanger bar brackets 40 (see fig. 1) may be provided on the base plate for temporarily mounting the hanger bars, the number of hanger bar brackets being a plurality of one or more, e.g., two, longitudinally extending rows. A round pipe or a square pipe serving as the hanging bar 50 is attached to a hanging bar bracket of a corresponding row so that the extending direction of the hanging bar is also the longitudinal direction (the longitudinal direction of the floor support plate). When needed, the sling/lifting rope of the crane (or called a crane) can be used for being tied on the lifting lever for carrying or hoisting on site, and the lifting lever can be detached after the floor supporting plate is installed in place for repeated use.

The bottom of the hanging bar bracket is fixedly connected to the bottom plate (the top surface/the upper surface of the bottom plate), and the connection can be realized in the modes of bonding, nailing, bolt (screw) connection and the like, so that the automatic operation surface on the production line is facilitated.

The upper part (or top) of the hanging bar bracket is provided with a hanging bar connecting structure for the fixed connection of the hanging bar on the hanging bar connection. Because the hanging bar is detached, the hanging bar connecting structure is not used, and the hanging bar connecting structure can adopt any structure which is easy to damage or disassemble, so that the hanging bar can be detached conveniently.

According to actual situations, the floor support plate can be provided with no hanging bar support (and hanging bars). In this embodiment (see fig. 4), the floor support plate comprises a base plate 10 and a reinforcing mesh located above the base plate, the reinforcing mesh is formed by welding a plurality of longitudinal reinforcing bars 21 and transverse reinforcing bars 23 at crossing positions, the base plate adopts a non-metal base plate, the reinforcing mesh is fixedly arranged above the base plate, a gap is reserved between the reinforcing mesh and the base plate, and the reinforcing mesh can be installed on the base plate through a plurality of reinforcing connecting pieces 30 or other suitable connecting modes. With respect to the embodiment in which the hanging bar support is provided, this embodiment is only that the hanging bar support is not required, and other portions may be the same as the various embodiments in which the hanging bar support is provided. When in carrying or on-site hoisting, the hoisting device suitable for the bottom plate or the steel bars/steel bar meshes can be used for hoisting, and if necessary, the hoisting device can also be manually moved.

A preferred hanging bar bracket embodiment is (see fig. 5): the upper part of the hanging bar bracket is provided with a longitudinal hanging bar through hole 41, the shape of which is similar to the shape of the outer edge (the peripheral surface or the side surface) of the hanging bar and is slightly larger than the outer edge of the hanging bar. The top surface of the hanging bar support is in an arc surface shape similar to the top of the hanging bar through hole, so that a sleeve structure positioned at the top of the hanging bar support is formed. The hanging bars are inserted through all hanging bar through holes (or sleeve structures) on the hanging bar brackets in the same row, two pin posts 53 are respectively inserted into pin holes (through holes, blind holes can be formed when appropriate) on the hanging bars, which are close to the outer sides of the two hanging bar brackets at two longitudinal ends, the pin posts (or pin holes) can be arranged close to other hanging bar brackets according to actual needs, or other appropriate quantity is adopted, so that the different pin posts are respectively blocked in two longitudinal directions of the corresponding hanging bar brackets, and therefore the position of the hanging bar in the longitudinal direction is limited. The pin can be slightly tapered, so that the top end part near the upper part of the pin is slightly larger than the pin hole, or the top end of the pin is provided with a lateral protruding structure for limiting, the pin is fixed on the pin hole, and the pin is prevented from being separated from the pin hole.

A plurality of vertical elongated holes 43 can be formed in the side wall of the sleeve structure (lateral side walls on two sides), the vertical elongated holes are elongated through holes with vertical dimensions obviously larger than the longitudinal dimension (namely the axial direction of the through holes), a larger vertical span (for example, 40% -80% of the diameter of the through hole of the hanging bar) is formed in the corresponding side wall of the sleeve structure, the distance between every two adjacent vertical elongated holes (namely, the width of the side wall between every two adjacent elongated holes) and the distance between the vertical elongated holes on two ends and the corresponding end face of the sleeve structure (namely, the width of the side wall on the longitudinal outer sides of the two end elongated holes) are correspondingly set according to actual needs, so that the sleeve structure is not broken in the hoisting process, when the top or the side wall of the sleeve structure is lifted (pried up) by a hammer or a screwdriver, the sleeve structure is broken from the side walls on two sides, and after the sleeve structure is broken, a hanging bar (can be directly connected with a pin post) is taken down from the hanging bar bracket.

According to practical needs, on the basis of the hanging bar support, a plurality of vertical long through holes arranged on the side wall of each side of the sleeve structure can be replaced by a round hole 45 (see fig. 8), and if necessary, two ends (two ends in the longitudinal direction) of the side wall of the sleeve structure can be respectively provided with a transverse groove (groove-shaped notch), wherein the height of the transverse groove is the same as the circle center of the round hole 45. Under the influence of the round hole (and corresponding transverse grooves if provided), the strength of the part where the round hole is arranged is lower than that of other parts of the sleeve structure, weak parts (low-strength parts) are formed, when the top or the side wall of the sleeve structure is bumped by a hammer or a steel rod/steel bar or lifted (pried up) by a screwdriver or the like, the side walls on the two sides of the sleeve structure are broken at the corresponding parts, the rest part of the round hole forms a transverse groove after the breakage, and transverse steel bars of an upper layer of steel bar net sheet can be supported on the transverse groove when needed.

According to the same technical concept, the weak portion can be formed on the side wall of the sleeve structure in any other suitable form (slotting, perforating, incomplete cutting, etc.), and the weak portion can be generally arranged in the vertical middle of the side wall (the weak portion is generally at the same height as the center/axis of the through hole of the hanging bar), and the sleeve structure is broken from the middle of the side wall under the condition of external force damage (for example, knocking the top of the sleeve structure), so that the hanging bar is conveniently taken out.

The structure such as the round hole, the transverse groove or the vertical strip hole which are arranged on the side wall of the sleeve structure and can reduce the strength can be called as a strength weakening structure.

The height of the hanging bar support (the hanging bar height after the hanging bar is installed) is higher than the height of the steel bar connecting piece (the height of the steel bar net sheet), so that the steel bar net sheet is prevented from interfering the hanging bar.

After the sleeve structure breaks, if the rest part (the part still connected to the bottom plate) of the hanging bar bracket is too high, cutting can be performed according to actual needs.

The bottom of the bar coupler 30 is also fixedly attached to the base plate (top/upper surface of the base plate) by means of bonding, stapling, bolting, etc. to facilitate automated work surfaces on the production line.

The reinforcing steel bar connecting piece is provided with a reinforcing steel bar clamping structure for fixedly connecting reinforcing steel bars on the reinforcing steel bar net piece, and further the reinforcing steel bar net piece is fixedly connected. The clamping mode is convenient for realizing automatic operation on the production line, and is beneficial to simplifying the process steps and required tools/equipment.
