Description

Technical Field

[0001] The invention relates to the casting thickness of a cast-in-place building floor slab, and in particular to a building floor slab casting thickness control component. Background Art

[0002] At present, cast-in-place concrete floor slabs such as frame structures, shear wall structures, and frame-shear structures are increasingly widely used in construction sites. The casting thickness of cast-in-place concrete floor slabs on construction sites is also over-thick or too thin to varying degrees. In order to strengthen the control of the hazards and waste caused by over-thickness and over-thinness of cast-in-place concrete floor slabs, practical measures are taken to strengthen control during the casting process of cast-in-place concrete floor slabs on construction sites to ensure that the thickness of the concrete protective layer and the floor slab is within the specification requirements.

[0003] The phenomenon of over-thickness of cast-in-place floor slabs in frame structures, shear wall structures, frame-shear structures, etc. is very easy to occur in projects, but it is often not taken seriously because the thickness of the over-thickness is generally small, only 10 to 15 mm. From the perspective of the owner, the over-thickness is actually firm and reliable, while from the perspective of the construction party, it is often considered to be a construction error and is easily overlooked. In fact, its harm cannot be ignored. Often in our actual measurement of buildings, it is difficult to ensure that the thickness of each household's floor slab meets the requirements, and fraud is often committed, resulting in large errors in floor height.

[0004] In our construction sites, there are many cast-in-place slab thickness control technologies, but these cast-in-place slab thickness control technologies can only guarantee the thickness of the cast-in-place slab at the embedded point, and cannot completely control the thickness of the entire cast-in-place slab; and, pouring concrete at night is common at construction sites. Because of the poor lighting and sensory perception of night construction, the thickness of the cast-in-place slab cannot be effectively controlled; however, the quality awareness of our construction site workers is often weak, and it is difficult to control the thickness of the entire cast-in-place slab. Summary of the invention

[0005] In order to solve the above technical problems, the present invention proposes a building floor slab casting thickness control component. Through the innovative research and development of the cast-in-place slab thickness control component, the harmfulness and waste caused by the excessive thickness or thinness of the cast-in-place floor slab concrete are completely eliminated, thereby ensuring that the thickness of the cast-in-place slab meets the requirements.

[0034] The technical solution adopted by the present invention to solve its technical problem is:

[0035] like Figure 2 As shown, a building floor casting thickness control component includes a right-angle base, a steel bar groove, a bolt column hole, an iron wire, a bottom plate steel bar, and a handle; before tying the bottom steel bar, the entire floor is arranged, and the right-angle base is placed in different positions, wherein the right-angle base is arranged to be a bolt column hole at the right angle, and the two ends of the right-angle base are arranged to be a steel bar groove, and the bottom plate steel bar is placed in the steel bar groove, and the steel bar groove is arranged to be a groove of multiple diameters, which can meet the placement and fixation of bottom plate steel bars with different diameters, and the thickness of the right-angle base steel bar groove is just used as the protective layer thickness of the bottom plate steel bar.

[0036] like Figure 1 As shown, a building floor casting thickness control component is provided, wherein a bolt column bar is arranged in the bolt column hole, and a hollow rotating hole is arranged at the uppermost end of the bolt hole column, and the bolt column bar is screwed into the bottom of the bolt column hole through a handle inserted into the rotating hole until it is screwed in and tightened, wherein the length of the bolt column hole and the bolt column bar are both 5cm, which size can not only ensure the strength of screwing in, but also better meet the economic efficiency and ensure the turnover of the bolt column bar; wherein, a plurality of grooves are symmetrically arranged on the front and back surface of the upper end of the bolt column bar, and the spacing between the grooves is 1mm, which more accurately controls the size of the plate thickness.

[0037] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, according to the actual thickness of the cast-in-place floor, an elevation disk is arranged in the groove of the bolt column, and the elevation disk is composed of two semicircles. A rotating shaft is arranged at the fixed connection of the two semicircles, and the elevation disk can rotate freely; a convex piece is arranged at the arc inside the elevation disk, which is used to insert into the groove of the bolt column; one end of the movable connection of the elevation disk is arranged in a concave ridge shape, and the other end is arranged in a convex ridge shape. After entering the groove through the convex piece, the elevation disk completely wraps the bolt column, wherein a concave ridge is arranged at the concave ridge shape, and a convex ridge is arranged at the convex ridge shape. Through the strong spring arranged at the bottom of the convex ridge, the concave ridges and the convex ridges at both ends of the elevation disk are combined and connected, and finally fixed on the bolt column as a whole to form a plate surface elevation control point; wherein, a semicircular outer ring outside the elevation disk is arranged with 3 equally spaced pull ring holes, and the pull ring holes on two adjacent elevation disks can be connected by a pull rope, thereby forming a large-scale elevation control surface of the plate surface, and the size of the plate thickness can be more accurately controlled.

[0038] like Figure 7As shown, one end of the pull rope is connected to the pull ring hole by multiple turns, and the other end is connected to the adjacent pull ring hole, and is also connected to the adjacent pull ring hole by multiple turns, until the pull rope between the two adjacent pull ring holes is in a taut state, ensuring effective control of the thickness of the entire plate.
