Description

Technical Field

[0001] The utility model relates to the field of construction, in particular to a tool for controlling the thickness of reinforced concrete floor slabs. Background Art

[0002] The current technology for controlling the thickness of concrete floor slabs requires using concrete pads with the same mix ratio and measuring elevations to control the height and thickness during construction. While this method is somewhat effective, the concrete pads on the upper part of the floor slab are easily stepped on during construction, resulting in deviations in the concrete floor slab elevation. The formwork elevation positioning and setting out around the concrete floor slab can only effectively control the area of the concrete floor slab surrounding the elevation line. For the central area of the larger floor slab, the control effect of the elevation setting out is not significant. Furthermore, the arch height of cast-in-place concrete beams and slabs is difficult to effectively control during concrete pouring, resulting in some cast-in-place reinforced concrete floor slabs failing to meet the arch height requirements of national standards.

[0030] The following combination Figure 1-Figure 2 The specific structure and use method of the reinforced concrete floor slab thickness control tool of the present invention are described.

[0031] Figure 1 The schematic diagram of the structure of the control tool for the thickness of reinforced concrete floor provided by the present invention is shown as follows: Figure 1 As shown, the tool for controlling the thickness of reinforced concrete floor slabs includes two abutment parts 100, a connecting assembly 200 and at least one set of clips 300, the two abutment parts 100 are arranged at intervals, one end of the connecting assembly 200 is connected to one of the abutment parts 100, and the other end of the connecting assembly 200 is connected to the other abutment part 100; the clip 300 includes a fixing buckle 310 and an adjusting buckle mechanism, the fixing buckle 310 and the adjusting buckle mechanism are arranged at intervals on the connecting assembly 200, and the position of the adjusting buckle mechanism on the connecting assembly 200 is adjustable.

[0032] The reinforced concrete floor slab thickness control tool provided by the present invention secures the tool against displacement during construction by snapping the clip 300 onto the main reinforcement 400 and then securing it to the main reinforcement 400 by tying. During the floor slab concrete pouring process, the concrete is poured to the top elevation of the upper abutment portion 100, thereby achieving the goal of controlling the concrete floor slab elevation and thickness. The reinforced concrete floor slab thickness control tool provided by the present invention accurately controls the thickness of the concrete floor slab, improving the quality of elevation and thickness control during the floor slab concrete pouring process.

[0033] In one embodiment of the present invention, the connection assembly 200 includes a steel bar, which is a hot-rolled ribbed steel bar. The hot-rolled ribbed steel bar can generally be HRB400 or HRB500 hot-rolled ribbed steel bar, which serves to connect the abutment parts 100 and the welding buckle 300 at both ends.

[0034] In one embodiment of the present invention, the abutment portion 100 is a rectangular parallelepiped. Of course, the shape of the abutment portion 100 is not limited to this and may also be a regular polyhedron or other shapes, as long as the bottom of the lower abutment portion 100 is flat and the top of the upper abutment portion 100 is flat. The lower abutment portion 100 abuts against the bottom formwork 500 of the floor slab to fix its own structure, and the upper abutment portion 100 is flush with the elevation of the concrete floor slab to be poured. The elevation of the upper abutment portion 100 is used as a reference to control the elevation of the entire concrete floor slab.

[0035] When in use, the steel bar is arranged vertically, the upper abutting part 100 is connected to the upper end of the steel bar, and the lower abutting part 100 is connected to the lower end of the steel bar. The material of the abutting part 100 is concrete, and the concrete grade of the abutting part 100 is the same as the concrete grade of the floor slab.

[0036] In a preferred embodiment of the present invention, fine steel bars are provided inside the abutment portion 100. The abutment portion 100 is composed of prefabricated concrete blocks and fine steel bars with the same mix ratio as the floor slab, so as to be applicable to concrete floor slabs of different concrete mix ratios and different thicknesses. When controlling the arch height of cast-in-place concrete beams and concrete slabs, control tools of different heights can be prefabricated according to the specifications, and arranged on both sides of the center line of the concrete beams and concrete slabs according to the thickness requirements. When pouring concrete, pour it according to the elevation to achieve the purpose of accurately controlling the arch height of the concrete beams and concrete slabs. Since the control tool of the present invention can be prefabricated in advance, it can be installed and constructed simultaneously with the fine steel bars, which greatly shortens the construction period of the entire concrete floor slab and improves work efficiency. It is applicable to steel bars of different models and specifications and concrete floor slabs of different thicknesses.

[0037] In a preferred embodiment of the present invention, the adjustment buckle mechanism includes a first sleeve 320 and an adjustment buckle body 330. The outer peripheral surface of the connecting component 200 is provided with an external thread 210. The first sleeve 320 is threadedly matched with the connecting component 200, and the adjustment buckle body 330 is connected to the outer peripheral surface of the first sleeve 320. Specifically, Figure 1 As shown, the outer circumference of the steel bar is provided with a section of external thread 210. The length of the external thread 210 determines the movement distance of the first sleeve 320, and thus determines the maximum distance between the adjusting buckle body 330 and the fixed buckle 310. The adjusting buckle body 330 is parallel to the fixed buckle 310 and perpendicular to the steel bar. The adjusting buckle body 330 and the first sleeve 320 are welded or integrally formed.

[0038] In a preferred embodiment of the present invention, the control tool includes two sets of buckles 300. Of course, the number of buckles 300 is not limited to two, and can also be three, four, or more, depending on the number of main ribs 400. The two sets of buckles 300 are spaced apart along the length of the connecting assembly 200, and the two adjustment buckle mechanisms are located on the sides of the two fixed buckles 310 that are away from each other.

[0039] like Figure 1 As shown, two fixing buckles 310 are arranged in parallel and at intervals in the middle of the steel bar, one adjusting buckle body 330 is arranged on the left side of the left fixing buckle 310, and the other adjusting buckle body 330 is arranged on the right side of the right fixing buckle 310. The fixing buckle 310 is a metal rod, and the outer diameter of the fixing buckle 310 is smaller than the outer diameter of the steel bar. The fixing buckle 310 is welded to the connecting assembly 200 or formed as one piece.

[0040] During use, the distance between the adjusting buckle body 330 and the corresponding fixing buckle 310 can be changed by rotating the first sleeve 320. The adjusting buckle body 330 and the fixing buckle 310 cooperate to clamp the main reinforcement 400. According to the different diameters of the main reinforcement 400, the distance between the adjusting buckle body 330 and the fixing buckle 310 can be adjusted in advance during prefabrication to ensure that they are firmly clamped on the main reinforcement 400. This plays a role in fixing the main reinforcement 400, controlling the spacing between the main reinforcement 400, controlling the thickness of the steel bar cover, and controlling the arch height of the floor slab, thereby achieving the purpose of controlling the thickness of the cast-in-place floor slab.

[0041] In a preferred embodiment of the present invention, a clamping portion (not shown) is provided on the side where the adjusting buckle body 330 and the fixing buckle 310 face each other. The clamping portion is a plurality of ridges or grooves arranged at intervals. By providing the clamping portion, the friction between the adjusting buckle body 330, the fixing buckle 310 and the main rib 400 is increased, thereby improving the stability of the control tool.

[0042] In a preferred embodiment of the present invention, thin steel bars are provided on the periphery of the abutment portion 100, which are embedded in the interior of the floor slab. Preferably, the thin steel bars on the periphery of the abutment portion 100 are connected to the thin steel bars inside the abutment portion 100. By providing thin steel bars on the periphery of the abutment portion 100 and embedding the thin steel bars in the interior of the floor slab, the connection strength between the abutment portion 100 and the floor slab is enhanced.

[0043] In a preferred embodiment of the present invention, the two abutting portions 100 have the same size, that is, the length, height, and width of the two abutting portions 100 are equal.

[0044] In a preferred embodiment of the present invention, the height of the control tool is equal to the thickness of the floor slab, and the height of the control tool is prefabricated in advance according to the thickness of the floor slab to be cast in place.

[0045] In another embodiment of the present invention, the difference from the above embodiment is that the connection assembly 200 in this embodiment includes two steel bars (not shown) and a second sleeve (not shown). The lengths of the two steel bars can be the same or different. The two steel bars are coaxially arranged, and the ends of the two steel bars that are far away from each other are connected to the two abutment portions 100 in a one-to-one correspondence. The ends of the two steel bars that are close to each other are provided with external threads, and the inner walls of the second sleeve at both ends are provided with internal threads. The ends of the two steel bars that are close to each other are inserted into the ends of the second sleeve in a one-to-one correspondence and engage with the inner wall threads of the second sleeve. During use, by rotating the two steel bars, the total length of the control tool can be changed, thereby enabling a single control tool to adapt to floor slabs of different thicknesses.

[0046] Method of using the reinforced concrete floor slab thickness control tool of the utility model: Figure 2 The schematic diagram of the use principle of the control tool for the thickness of reinforced concrete floor provided by the utility model is illustrated as follows: Figure 2 As shown, a control tool is prefabricated based on the required distance between the main reinforcement bars 400 of the concrete slab and the thickness of the concrete slab. The position of the first sleeve 320 is adjusted so that the distance between the adjusting buckle body 330 and the fixing buckle 310 is equal to the outer diameter of the main reinforcement bar 400, the distance between the two clips 300 is equal to the spacing between the main reinforcement bars 400 of the concrete slab, and the height of the control tool is equal to the thickness of the concrete slab. The clips 300 of the control tool are then clipped onto the main reinforcement bars 400 of the concrete slab and tied with binding wire to achieve a secure fixation. During the concrete pouring process for the concrete slab, pouring is stopped when the top elevation of the upper abutment portion 100 is reached, that is, when the concrete reaches the concrete slab elevation line 600.

[0047] The reinforced concrete floor slab thickness control tool provided by this utility model is applicable to reinforced concrete floor slabs of various thicknesses, mix ratios, steel bar specifications and types, and steel bar cover thicknesses. The application of this control tool can significantly improve the acceptance rate of concrete floor slab thickness and the spacing between 400 main bars during the first inspection. While ensuring the quality of floor slab construction, it also significantly reduces the manpower input of construction and inspection personnel, playing a positive role in optimizing the construction schedule.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
