Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, in particular to a concrete elevation control device. Background Art

[0002] In existing technologies, concrete elevation control is usually done by reserving control lines such as the 50 line on the vertical reinforcement. Personnel then set elevation control lines horizontally and embed slab thickness reinforcement heads in the area to be poured to control the concrete pouring. However, due to the different levels of skills of operators and the difficulty of construction by personnel pulling lines, the construction efficiency is low, labor costs are wasted, and the control of concrete elevation is difficult and easily affects the pouring accuracy. After the concrete pouring is completed, some floor slabs are uneven, and some reinforcements have insufficient protective layers and exposed reinforcements; embedded reinforcement heads are prone to rust, affecting the construction quality; the elevation and flatness of the structural floor slabs are difficult to meet the design and specification requirements. Some shantytown renovation projects have extremely high requirements for elevation control. In order to make the floor slab structure layer meet the standard acceptance standards and the overall cast-in-place structure look good, it is necessary to benchmark high quality and then carry out repairs, which not only wastes a lot of labor and materials, but also the quality of the repaired parts is uneven. There are technical problems such as difficulty in controlling the elevation during concrete pouring, rust on the embedded steel bar heads, which affect the construction quality, labor-intensive construction, and the need to repair the concrete after construction due to unevenness or poor appearance, resulting in high construction costs.

[0023] like Figures 1 to 5 The figure shows a schematic diagram of an embodiment of a concrete elevation control device according to the present invention. The device comprises a fixing component and a positioning component. The fixing component comprises a spool and multiple standard lines 2, each of which is wound around the spool. The positioning component comprises an adjusting member 3 and a positioning member 4 for positioning the concrete elevation. The adjusting member 3 is located at the bottom of the spool and is movably connected to the positioning member 4 to adjust the vertical height. The present invention has a simple structure, low manufacturing cost, and is easy to use. It can quickly level the structural floor according to the designed elevation, ensuring the flatness of the structural floor after formation, reducing post-production repairs, eliminating the need for the construction process of the floor screed layer, saving manpower and material resources, and shortening the construction period.

[0024] In this embodiment, the fixing component also includes a wire box 1, a spool is rotatably arranged in the wire box 1, and one end of each standard wire 2 is fixedly connected to the spool and wound outside the spool, and the other end extends outside the wire box 1 for adjustment and control. The wire box 1 can seal and protect the spool and multiple standard wires 2, extending the service life of the device. The rotation connection method of the spool and the wire box 1 can be flexibly selected based on the common technical knowledge of those skilled in the art. The rotation can be manually controlled by adding a rocker, or it can be designed for automatic control. The present invention is not limited to this, and can meet the functions of pulling, retracting, and fixing the length of multiple standard wires 2. In this embodiment, the number of standard wires 2 is two, and the wire box 1 has symmetrical perforations on both sides, and the two standard wires 2 extend from the perforations on both sides respectively. In other embodiments, the number of standard wires 2 can be more than two, and each extends in different directions. In different embodiments, each standard wire 2 can also be provided with a clamping ring at the end away from the spool that can be fixed to the outside of the wire box 1. The clamping ring not only prevents the standard wire 2 from being completely retracted into the wire box 1, but also can be used to fix the standard wire 2 to the steel bar or wall stud.

[0025] In other embodiments, the surface of the standard line 2 is provided with scale lines that can be used for measurement. The standard line 2 can be made of a fiber line with a scale, which makes it convenient for personnel to locate the concrete elevation while quickly measuring the distance between the concrete elevation control device and other monitoring points, thereby improving the positioning and measurement efficiency.

[0026] In this embodiment, the adjusting member 3 has a plurality of through holes 31 at intervals along the vertical direction, and the positioning member 4 can be inserted through any through hole 31 to locate the elevation of the concrete 7. In this embodiment, the adjusting member 3 can be made of a steel pipe, and the positioning member 4 can be made of a screw. By using common materials, it can be reasonably adjusted and used according to the actual situation on site. The production cost is low and it is easy to promote and popularize, which not only ensures the control of the concrete pouring elevation and the construction quality, but also reduces the construction difficulty and facilitates personnel operation, improves the flatness and appearance quality of the concrete, reduces later repairs, and saves maintenance costs and labor costs; in other embodiments, the adjusting member 3 can have a long hole penetrated vertically, and the positioning member 4 is slidably set in the long hole and fastened by a threaded connection with a nut or the like; in different embodiments, the positioning member 4 can also be slidably sleeved on the outside of the adjusting member 3 and fastened by inserting bolts and nuts.

[0027] In various embodiments, the surface of the adjusting member 3 is further provided with markings for adjusting the positioning member 4. The markings may be scale lines or universal concrete elevation values ​​that are paired with elevation control lines 6, such as the 50-meter line or the 1-meter line. The marking design facilitates construction personnel to directly confirm the relative positions of the positioning member 4 and the adjusting member 3 through the predetermined elevation control lines 6, thereby improving the installation efficiency of the positioning member 4 and the adjusting member 3, thereby improving overall construction efficiency, reducing the difficulty of concrete elevation positioning, reducing operational differences between different construction personnel, and improving concrete elevation positioning accuracy and construction quality.

[0028] In this embodiment, the concrete level control device further includes a connecting component 5, which is positioned at the bottom of the spool and vertically connected to the adjusting member 3. In this embodiment, the connecting component 5 and the adjusting member 3 are vertically connected in a T-shaped arrangement. In this embodiment, the top area of ​​the connecting component 5 is larger than that of the wire box 1 to facilitate installation, and the bottom area of ​​the connecting component 5 is larger than the top area of ​​the adjusting member 3. During operation, when moving the concrete level control device, a person can grasp the adjusting member 3 and abut against the bottom of the connecting component 5 to prevent the concrete level control device from slipping out of their hands. The connecting component 5 and the adjusting member 3 form a T-shaped handle, facilitating easy movement.

[0029] The working process of this utility model is as follows:

[0030] First, confirm the design slab thickness and other dimensions of the concrete pouring at the construction site, and adjust the positioning member 4 to the corresponding height according to the construction requirements. In this embodiment, the screw needs to be inserted into the corresponding through hole 31 and fixed.

[0031] At least two standard wires 2 are pulled out of the wire box 1 to the required length, and are respectively aligned with the elevation control wire 6 and fixed. In common construction, the elevation control wire is usually selected from a 50-meter wire or a 1-meter wire. In different construction scenarios, it can also be adaptively adjusted according to construction requirements. Each standard wire 2 can have its end away from the spool fixed to a nearby wall column or steel bar. During the fixing process, multiple standard wires 2 need to be tightened and kept straight. The adjustment member 3 is suspended on the formwork 8 that can support concrete 7 through multiple standard wires 2, and the bottom of the adjustment member 3 is abutted against the top of the formwork 8. In this embodiment, the bottom of the adjustment member 3 is a flat surface to improve the stability of the concrete elevation control device when it is fixed to the top of the formwork 8. The concrete elevation control device can be placed in the pouring area before concrete pouring to monitor the concrete pouring elevation, or the adjustment member 3 can be inserted into the concrete pouring surface during the finishing to detect whether the concrete pouring elevation meets the specifications. By observing the relative position of the positioning member 4 and the concrete 7 pouring surface, when the bottom of the positioning member 4 contacts the concrete 7, it can be determined that the concrete surface elevation meets the specification requirements. After use, the adjusting member 3 can be pulled out from the concrete, and the concrete elevation control device can be disassembled for reuse, which not only saves costs but also avoids the hidden danger of rusting of the embedded plate thickness steel bar heads used to control concrete pouring affecting the pouring quality.

[0032] In this specific usage scenario, when the positioning member 4 is not set in the bottom through hole 31, after the adjusting member 3 is pulled out, the concrete 7 poured into the device from the bottom through hole 31 needs to be cleaned for subsequent reuse; in another usage scenario, the through hole 31 provided under the positioning member 4 can also be sealed after the positioning member 4 is fixed, and then the adjusting member 3 is placed in the concrete, saving cleaning time and increasing service life.

[0033] The utility model can make the control of concrete pouring elevation more convenient and accurate, ensure the construction quality while reducing later repairs, saving material and labor costs, and has the advantages of simple structure, low production cost, and reusable device, which can improve construction efficiency and quality and reduce construction and maintenance costs.

[0034] The above embodiments of the present invention are described in detail. However, the above contents are only preferred embodiments of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
