In the embodiment of the present invention, as shown in fig. 1 and 2, the laminated slab 10 includes a concrete body 200, a reinforcement layer (lower reinforcement layer) 300, and truss ribs 400. The upper surface of the concrete body 200 is the plate surface 10a of the laminated plate 10. The reinforcement layer (lower reinforcement layer) 300 is located within the concrete body 200. Truss rib 400 includes a lower chord rib 410, an upper chord rib 420, and web members ribs 430, web members 430 connecting lower chord rib 410 and upper chord rib 420. Lower chord tendons 410 and portions of web tendons 430 are located in casting layer 400, and upper chord tendons 420 are suspended above deck 10a of composite sheet 10. The clearance height between the upper chord rib 420 and the plate surface 10a is the clearance height between the upper chord rib 420 and the plate surface 10a.
In the production of the above-mentioned composite slab 10, a reinforcing bar layer (lower reinforcing bar layer) 300 and truss ribs 400 are placed on a mold, and then concrete is poured on the mold, and after the concrete is hardened, the above-mentioned composite slab 10 is obtained. However, the laminated slab 10 manufactured by the above method often has the problems of too small clearance height and too large clearance height, for example, the problem that the thickness of the middle part of the laminated slab 10 is too thick to cause the clearance height between the lower chord rib 410 of the truss rib 400 and the plate surface 10a to be too small, and the problem that the clearance height between the lower chord rib 410 of the truss rib 400 and the plate surface 10a is too large due to the floating of the truss rib 400 during concrete vibration.
The above-mentioned superimposed sheet 10 is usually used for making the floor in the follow-up, when adopting above-mentioned superimposed sheet 10 to make the floor, need wear to establish electromechanical devices such as spool, line box in the headroom between last chord rib 420 and the face 10a, the headroom height between last chord rib 420 and the face 10a is too little can lead to the job site unable to pass electromechanical devices such as spool, line box in the headroom, increases construction difficulty, influences the construction progress. When the above laminated slab 10 is used to manufacture a floor slab, it is necessary to place a reinforcing bar layer (upper reinforcing bar layer) on the slab surface 10a of the laminated slab 10, and then pour concrete, and after hardening the concrete, the floor slab is obtained, wherein the electromechanical devices such as a line pipe and a line box and the upper reinforcing bar layer are all located in the floor slab, the concrete between the upper reinforcing bar layer and the upper surface of the floor slab is a protective layer (upper protective layer), and the concrete between the lower reinforcing bar layer and the lower surface of the floor slab (i.e., the lower surface of the laminated slab 10) is also a protective layer (lower protective layer). The excessive clearance height caused by the floating of the truss rib 400 can cause insufficient thickness of the protective layer (upper protective layer) of the upper reinforcing steel bar layer of the floor slab (namely, insufficient thickness of the protective layer of the reinforcing steel bar of the surface layer of the cast-in-situ layer of the floor slab), even the condition of rib exposure can occur, and the engineering quality is seriously affected.
In order to solve the above problems, as shown in fig. 3 to 5, the present invention provides a clearance controller 500 for controlling the clearance height between truss rib 400 and the panel surface 10a of the laminated panel 10 during the process of manufacturing the laminated panel 10.
In the present embodiment, the clearance controller 500 is used to control the clearance height between the plate surface 10a of the composite plate 10 and the upper chord 420 of the truss rib 400. The headroom controller 500 includes a mounting portion 510 and a height control portion 520 connected. The mounting portion 510 is for connection with the upper chord rib 420 of the truss rib 400. The height control part 520 is used to control the clearance height between the plate surface 10a of the composite plate 10 and the upper chord rib 420 of the truss rib 400.
By applying the above clearance controller 500 to the production process of the laminated slab 10, the condition of the clearance height of the truss rib 400 can be found in real time, and whether the clearance height of the truss rib 400 meets the design requirement (i.e. whether the clearance height is the preset clearance height) can be seen at a glance by the clearance controller 500, and the improvement can be made in time, so that the production quality of the laminated slab 10 is improved.
For example, in some embodiments, when the end of the height control portion 520 away from the mounting portion 510 contacts the plate surface 10a of the laminated plate 10, the clearance height between the plate surface 10a of the laminated plate 10 and the upper chord 420 of the truss rib 400 is the preset clearance height. Thus, when the concrete is vibrated after the concrete is poured on the mold, if the part of the height control portion 520 is submerged in the concrete, it means that the concrete at the position of the laminated board 10 is too thick, and it is necessary to manually process the end of the height control portion 520 away from the mounting portion 510 to contact the board surface 10a of the laminated board 10, for example, it is necessary to manually remove part of the concrete, and during the manual removal of part of the concrete, part of the concrete at the position can be taken out of the mold, or part of the concrete at the position can be moved to other areas lacking the concrete of the mold; if the end of the height control portion 520 far away from the mounting portion 510 is suspended above the concrete, at this time, it is checked whether the thickness of the concrete at the location meets the standard, if the thickness does not meet the standard, concrete is continuously poured, if the thickness meets the standard, it is indicated that the truss rib 400 floats upwards, and the truss rib 400 needs to be pressed down until the truss rib 400 reaches a preset position (the position where the truss rib 400 cannot continuously move downwards can be the preset position of the truss rib 400). After the truss rib 400 reaches the predetermined position, the end of the height control portion 520 remote from the mounting portion 510 is typically brought into contact with concrete, but an exception may occur. When an exception occurs, if a part of the height control portion 520 is submerged in the concrete, it means that the concrete at the location of the laminated slab 10 is too thick, and it is necessary to perform manual handling, and if the end of the height control portion 520 remote from the mounting portion 510 is suspended above the concrete, it is necessary to confirm whether the thickness detection is accurate or to find other reasons.
It should be noted that, in practical application, a person skilled in the art may determine the preset headroom according to specific construction requirements. For example, when the total thickness of the floor slab is 130mm, the laminated plate thickness is 60mm, the diameter of the reinforcing bars of the reinforcing bar layer (upper and lower reinforcing bar layers) is 8mm, the truss rib is a75, and the thickness of the protective layer (upper and lower protective layers) is 15mm, the preset clearance height may be 30mm. After the preset headroom is determined, a headroom controller 500 of an appropriate size may be selected. That is, in practical application, different types of clearance controllers 500 may be configured for different types of superimposed sheets 10 according to the construction requirements.
For another example, in some embodiments, the height control portion 520 is provided with graduation marks and indicia (e.g., numerical indicia) corresponding to the graduation marks. Thus, when concrete is vibrated after the concrete is poured on the mold, if the scale mark of the height control portion 520 sunk in the concrete is higher than the preset scale mark, it means that the concrete at the position of the laminated slab 10 is too thick, and manual treatment is needed, so that the scale mark of the height control portion 520 sunk in the concrete is the preset scale mark, for example, part of the concrete needs to be manually removed, and part of the concrete at the position can be taken out of the mold in the process of manually removing part of the concrete, or part of the concrete at the position can be moved to other areas lacking the concrete of the mold; if the scale mark of the height control portion 520 sinking in the concrete is lower than the preset scale mark, or if the end of the height control portion 520 far away from the mounting portion 510 is suspended on the concrete, firstly checking whether the thickness of the concrete at the position meets the standard, if the thickness does not meet the standard, continuing to pour the concrete, if the thickness meets the standard, indicating that the truss rib 400 floats up, the truss rib 400 needs to be pressed down until the truss rib 400 reaches the preset position (the position where the truss rib 400 cannot continuously move downwards can be the preset position of the truss rib 400). After the truss rib 400 reaches the preset position, the scale mark of the height control portion 520 submerged in the concrete is usually the preset scale mark or the end of the height control portion 520 away from the mounting portion 510 may contact the concrete, but an exception may occur. When an exception occurs, if the scale mark of the height control portion 520 is higher than the preset scale mark or a part of the height control portion 520 is submerged in the concrete, it means that the concrete of the laminated slab 10 is too thick, and it needs manual treatment, if the scale mark of the height control portion 520 is lower than the preset scale mark or the end of the height control portion 520 far from the installation portion 510 is suspended above the concrete, it needs thickness detection whether to be accurate or to find other reasons.
It should be noted that, when the preset clearance height is 30mm, if the height control portion 520 has no scale line, the length of the height control portion 520 may be 30mm, that is, the clearance controller 500 with the length of the height control portion 520 being 30mm may be selected; if the height control portion 520 has graduation marks, the length of the height control portion 520 may be 30mm or greater than 30mm, for example, may be 35mm, 40mm, 45mm, or the like, that is, if the height control portion 520 has graduation marks, the clearance controller 500 of the same model may be applied to the production of laminated boards 10 of different models. When the preset clearance height is 30mm, the height control portion 520 has graduation marks, and the length of the height control portion 520 is 35mm, the marks of the graduation marks of the height control portion 520 gradually increase in a direction away from the mounting portion 510, and then the preset graduation marks are 30mm.
It should be noted that, when the preset headroom is 30mm, the length of the height control portion 520 may be less than 30mm, for example, the length of the height control portion 520 may be greater than or equal to 27mm and less than 30mm, regardless of whether the height control portion 520 has the graduation marks. Because in the actual construction process, the production requirement can be satisfied if the error between the actual clearance height of the laminated plate 10 and the preset clearance height is controlled within 3 mm. That is, the length of the height control part 520 of the headroom controller 500 may be equal to or greater than the preset headroom, or may be less than the preset headroom.
In this embodiment, the mounting portion 510 is detachably connected to the upper chord rib 420 of the truss rib 400. Thus, the clearance controller 500 is convenient to install, and the clearance controller 500 can be recycled, so that the cost is reduced. It will be appreciated that in other implementations, the clearance controller 500 may be fixedly connected to the upper chord 420 of the truss rib 400, and in this case, the clearance controller 500 may be buried in the floor slab during the subsequent concrete casting process.
In this embodiment, the mounting portion 510 is rotatable about the upper chord 420. The end surface of the height control part 520 far away from the mounting part 510 is an arc surface, and the arc surface protrudes outwards relative to the mounting part 510. Thus, when part of the height control part 520 is submerged in the concrete, that is, when the concrete buries the lower end of the height control part 520, even if the concrete is hardened, the mounting part 510 can be pulled out rotationally around the upper chord rib 420 of the truss rib 400, because the outer edge (cambered surface) of the height control part 520 is a circle centered on the center of the upper chord rib 420 of the truss rib 400, the height control part 520 is submerged in the concrete and has a groove, and the height control part 520 can be pulled out rotationally around the groove. That is, the clearance controller 500 of the above-described structure is very convenient to detach from the concrete.
In this embodiment, the mounting portion 510 is a U-shaped buckle. In this way, not only is it very convenient to achieve the detachable connection of the mounting portion 510 with the upper chord rib 420 of the truss rib 400, but also it is very convenient to achieve the rotation of the mounting portion 510 around the upper chord rib 420. And the U-shaped buckle can be large or small, is suitable for truss ribs of all types, is firm in fixation and is not easy to fall off. It will be appreciated that in other embodiments, the bar member may be wound around the upper chord rib 420 of the truss rib 400 to form a cylindrical portion, and the two ends of the bar member are locked with screws, so that the mounting portion 510 may be formed, and the mounting portion 510 may be detachably connected to the upper chord rib 420 of the truss rib 400 or may rotate around the upper chord rib 420.
In this embodiment, the mounting portion 510 is integrally formed with the height control portion 520. In this manner, the headroom controller 500 is very convenient to fabricate. In this embodiment, the mounting portion 510 and the height control portion 520 are made of plastic. Specifically, in the present embodiment, the mounting portion 510 and the height control portion 520 are made of PVC (Poly Vinyl Chloride ).
In this embodiment, the height control portion 520 is a sector dial. The fan-shaped appearance is convenient for early installation and later disassembly, and even if the appearance is disturbed to generate angle deviation in the production process, the measurement is not influenced, and the scale mark is obvious. It will be appreciated that in other embodiments, the height control portion 520 may also include a mounting portion 510 connected to the vertical portion and an arcuate portion connected to the vertical portion.
In this embodiment, both surfaces of the sector dial have graduation marks and digital marks corresponding to the graduation marks.
