Abstract
The invention discloses a device for controlling the thickness and elevation of a composite floor slab. The device comprises a control block, a fine adjustment supporting rod, a fine adjustment supporting rod support and a locknut. The control block is a concrete block with the top being a plane, the upper end of the fine adjustment supporting rod is fixedly connected with the control block, the lower end of the fine adjustment supporting rod is movably connected with the fine adjustment supporting rod support, a thread bolt is arranged at the lower end of the fine adjustment supporting rod, the locknut is movably screwed to the thread bolt above the fine adjustment supporting rod support, one end of the fine adjustment supporting rod is provided with a screw thread arranged in the length direction of the fine adjustment supporting rod support, and the thread bolt is matched with the screw thread. Operation is convenient, the thickness and elevation of the composite floor slab are effectively controlled, the grouting thickness of a grouting layer at the bottom of an upper layer of prefabricated shear wall board is further effectively controlled, construction efficiency and engineering quality are improved, the wet construction workload of operators on a construction site is reduced, and meanwhile the factorization and modularization level of building industrialization products is further reflected.
Description
Technical field
The invention belongs to industrialization of construction industry field, particularly relating to a kind of device for controlling laminated floor slab thickness and absolute altitude.
Background technology
At present, civil building engineering part adopts industrialization of construction industry construction technology, its laminated floor slab thickness and absolute altitude control to be typically employed in method reserved steel bar doing absolute altitude control point, in the cast-in-place part concreting process of laminated floor slab, when the concrete of building by absolute altitude control point cover or on-the-spot absolute altitude control point distant time, operating personnel are difficult to accurately control slab thickness and planeness, the vision often only relying on individual carries out operation control, because the operant level of operating personnel is uneven, laminated floor slab thickness and absolute altitude is caused to be difficult to meet the requirements, not only time-consuming, and control effects is poor, even potential safety hazard is brought to architecture quality time serious, because the connecting sewing between upper strata precast shear wall plate and lower floor's floor is at about 20mm, next stacked conjunction slab thickness and absolute altitude control bad, directly limit construction quality and the progress of the installation of last layer prefabricated panel, laminated floor slab absolute altitude exceedes design elevation, grouting layer thickness low LCL bottom last layer precast shear wall will be caused, laminated floor slab thickness is not enough, grouting layer thickness bottom last layer precast shear wall will be caused too high, not only time-consuming, waste material, also has a strong impact on the quality of grouting layer bottom precast shear wall, laminated floor slab thickness and absolute altitude control bad, leave hidden danger also to follow-up cement mortar surface construction, the cement mortar surface of thickness uniformity should often make the larger cement screedn of thickness difference, not only waste material, also easily cause and shrink uneven during setting and harden and produce the common quality defect such as crack, hollowing.
Summary of the invention
The object of the present invention is to provide a kind of device for controlling laminated floor slab thickness and absolute altitude, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, present invention employs following technical scheme:
A kind of device for controlling laminated floor slab thickness and absolute altitude, comprise controll block, fine setting support bar, fine setting support bar bearing and locking nut, the concrete block of controll block to be top be plane, fine setting post upper is fixedly connected with controll block, its lower end is flexibly connected with fine setting support bar bearing, fine setting support bar lower end is silking bolt, and locking nut activity screws on the silking bolt above fine setting support bar bearing.
Preferably, the material of finely tuning support bar is round steel.
Preferably, fine setting support bar bearing one end offers screw thread, and silking bolt matches with screw thread.
Preferably, screw thread is offered along fine setting support bar standoff length direction.
Compared with prior art, beneficial effect of the present invention is as follows:
When laminated floor slab pre-erection makes, fine setting support bar bearing is arranged on the top of precast plate by space distance control, before the cast-in-place part concreting of laminated floor slab, by fine setting support bar and fine setting support carriers bolton pre-buried on laminated floor slab pre-erection finely tune make controll block end face and flooring elevation control consistent, then support bar will be finely tuned with locking nut and lock; Carry out levelling by floating rule along controll block top when carrying out the concreting of laminated floor slab cast-in-place part, the thickness of laminated floor slab and absolute altitude just obtain effective control, so not only easy to operate, the thickness and the absolute altitude that effectively control laminated floor slab, also effectively control the slip casting thickness of grouting layer bottom last layer precast shear wall plate, improve efficiency of construction and workmanship, decrease the wet trade workload of job site operator, embody the batch production of industrialization of construction industry product, modularization level further simultaneously.
Accompanying drawing explanation
Fig. 1 is the structural representation of the device for controlling laminated floor slab thickness and absolute altitude.
Fig. 2 is the scheme of installation of the device for controlling laminated floor slab thickness and absolute altitude.
Detailed description of the invention
Below in conjunction with embodiment, preferred embodiment of the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of device for controlling laminated floor slab thickness and absolute altitude, comprise controll block 1, fine setting support bar 2, fine setting support bar bearing 3 and locking nut 4, controll block 1 for top be the concrete block of plane, the material of fine setting support bar 2 is round steel, fine setting support bar 2 upper end is fixedly connected with controll block 1, its lower end is flexibly connected with fine setting support bar bearing 3, fine setting support bar 2 lower end is silking bolt 21, locking nut 4 activity screws on the silking bolt 21 above fine setting support bar bearing 3, there is the screw thread 31 offered along fine setting support bar bearing 3 length direction fine setting support bar bearing 3 one end, silking bolt 21 matches with screw thread 31.
The present invention proposes a kind of device for controlling laminated floor slab thickness and absolute altitude, before laminated floor slab construction, fine setting support bar 2 is embedded in concrete controll block 1, and by controll block 1 maintenance to some strength, before the concreting of laminated floor slab cast-in-place part 5, by fine setting support bar 2 and fine setting support carriers 3 bolton pre-buried on laminated floor slab pre-erection 6 finely tune make controll block 1 end face and flooring elevation control consistent, then with locking nut 4, fine setting support bar 2 to be locked; Carry out levelling by floating rule along controll block top when carrying out 5 concreting of the cast-in-place part of laminated floor slab, the thickness of laminated floor slab and absolute altitude just obtain effective control.
Above embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
