Description

Technical Field

[0001] This utility model relates to the technical field of anti-cracking devices for flooring, and in particular to an anti-cracking control device for large-span flooring construction in factories. Background Technology

[0002] As environmental requirements for factory buildings increase, factory floors are often constructed using concrete pouring. However, uneven heating of the concrete floor can cause localized expansion or contraction, leading to cracking. While small-area concrete pours may not exhibit significant expansion and cracking, large-span pours with varying temperatures and thicknesses increase the likelihood of cracking.

[0003] To avoid and reduce cracking of concrete floors, steel reinforcement cages are typically used during pouring to strengthen the concrete and reduce the interaction between concrete sections, or expansion joints are opened to avoid the interaction forces generated by the expansion of concrete sections.

[0004] Of the methods mentioned above for preventing floor cracking, the steel reinforcement cage requires specialized steelworkers to assemble, and the spacing between the steel bars cannot be made completely uniform during assembly, making the process very cumbersome. While expansion joints can be created using a cutting machine, their aesthetics and water-proofing effects are poor. Water can easily seep into the floor through the expansion joints, causing a mismatch in the expansion coefficients between the interior and exterior surfaces during thermal expansion and contraction, ultimately leading to floor cracking.

[0005] Therefore, this application proposes a crack prevention control device for large-span factory floor construction to solve the aforementioned problem of the troublesome process of avoiding or reducing cracking of concrete flooring. Utility Model Content

[0006] In view of the shortcomings of the prior art mentioned above, the purpose of this utility model is to provide a crack prevention control device for large-span factory floor construction, which can solve the problem of avoiding cracking of concrete floor mentioned in the prior art.

[0007] To achieve the above and other related objectives, this utility model provides a crack prevention control device for large-span factory floor construction, comprising multiple partition frames, each of which can be spliced ​​together, and each partition frame having a steel cage arranged in a crisscross pattern inside.

[0008] Each of the partition frames has a connecting skirt on its bottom outer surface, which is used to separate two adjacent partition frames.

[0009] The bottom of the dividing frame is provided with a reinforcing frame, which can extend into the foundation.

[0010] Preferably, gaps are left between the bottom and top of the reinforcing cage and the bottom and top of the partition frame, and gaps are left between the longitudinal reinforcing bars and the transverse reinforcing bars in the reinforcing cage.

[0011] Preferably, the side wall of the partition frame is provided with a plurality of permeation holes at equal intervals, and each permeation hole is provided between two adjacent reinforcing bars of the reinforcing cage.

[0012] Preferably, connecting bolts are provided at all four corners of the top of the connecting skirt;

[0013] The two connecting skirts are connected and fixed together by connecting bolts and fasteners.

[0014] Preferably, the fastener includes a connecting piece and a retaining nut;

[0015] The connecting piece is sleeved on two adjacent connecting bolts, and the fixing nut is threaded onto the connecting bolts to limit the position of the connecting piece.

[0016] Preferably, the surface of the connecting skirt is provided with a plurality of connecting holes at equal intervals.

[0017] Preferably, the connecting holes provided on the two connecting skirts can be connected by anchors.

[0018] Preferably, the bottom of the reinforcing frame is provided with a cutting edge.

[0019] As described above, the anti-cracking control device for large-span factory floor construction of this utility model has the following beneficial effects:

[0020] This invention involves setting up multiple partition frames and laying them on the ground, then pouring concrete into the partition frames and the gaps between them, so that the concrete is divided into several small pieces. When the concrete expands and contracts with temperature, the force between individual concrete pieces is smaller, thereby avoiding cracking and reducing the degree of cracking.

[0021] Meanwhile, pre-welding steel cages into the partition frame can increase the strength of the concrete during pouring and further prevent cracking due to stress. It also eliminates the need for professional steelworkers to tie the steel on-site, thus improving convenience.

[0022] This utility model provides a connecting skirt at the bottom of the outer surface of the partition frame and connecting bolts at the four corners of the top of the connecting skirt. During assembly, the connecting piece can be fitted onto two adjacent connecting bolts and then fixed with a fixing nut, avoiding the impact of pouring concrete, which could cause displacement and misalignment between the partition frames.

[0023] Meanwhile, the fixing method using connecting plates and fixing nuts in conjunction with connecting bolts is simple to operate, and the pre-set steel cage inside the partition frame allows even non-professionals to quickly arrange and fix it, thus improving construction efficiency.

[0024] This invention features permeation holes on the sides of the partition frame and connection holes on the connecting skirt. When concrete is poured, the concrete permeates into the permeation holes and connection holes, thereby forming a whole with all the concrete in the partition frame, thus improving the integrity and strength of the concrete.

[0025] This invention features a reinforcing frame at the bottom of the partition frame. When installing the partition frame, the reinforcing frame can be inserted into the foundation, thereby supporting and limiting the partition frame through the foundation, preventing the concrete from pushing the entire device away when the concrete floor is poured.

[0026] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0034] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0035] Please see Figures 1 to 5It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, this utility model provides a crack prevention control device for large-span factory floor construction, including multiple partition frames 1, each of which can be spliced ​​together to form the framework of the factory floor. Each partition frame 1 contains a crisscrossing steel cage 2. The steel cage 2 is pre-welded to the inside of the partition frame 1, forming a steel reinforcement structure to improve concrete strength and reduce the possibility of concrete cracking.

[0037] Each partition frame 1 has a connecting skirt 3 on its bottom outer surface, which allows multiple partition frames 1 to connect to each other. The connecting skirt 3 also separates adjacent partition frames 1, creating a buffer zone between them to dissipate the expansion force of the concrete. When pouring concrete, the buffer zone is also filled with concrete, ensuring the concrete covers all partition frames 1 and makes the surface of the floor level. When the concrete expands, the force of the expansion acts first on the partition frames 1, eliminating and reducing the compression between the concrete sections.

[0038] A reinforcing frame 4 is installed at the bottom of the partition frame 1, and the reinforcing frame 4 extends into the foundation. The reinforcing frame 4 extends into the foundation to limit the installation position of the partition frame 1, thereby preventing displacement of the partition frame 1 due to the impact of concrete pouring. This structure effectively prevents floor cracking, and can be quickly installed by non-professional operators.

[0039] like Figures 1-3As shown, in some embodiments, gaps are left between the bottom and top of the reinforcing cage 2 and the bottom and top of the partition frame 1. After concrete is poured, the reinforcing cage 2 can be positioned in the middle of the concrete, thereby supporting and traction the upper and lower layers of concrete, increasing the strength of the concrete and reducing the possibility of concrete expansion and cracking. Gaps are left between the longitudinal and transverse reinforcing bars in the reinforcing cage 2, making the poured concrete more layered. When some parts of the concrete expand, the expansion force is reduced.

[0040] like Figures 1-3 As shown, in some embodiments, the sidewall of the partition frame 1 of this invention is provided with a plurality of permeation holes 11 at equal intervals. After concrete is poured, the concrete can improve its adhesion to the partition frame 1 through the permeation holes 11. At the same time, the concrete can extend through the permeation holes 11 into the buffer zone between two adjacent partition frames 1, mix and solidify with the concrete in the buffer zone, and improve the overall connection line of the concrete. This avoids the concrete from being segmented by the partition frame 1, resulting in weak and brittle joints. Each permeation hole 11 is set between two adjacent reinforcing bars of the reinforcing cage 2 to improve the connection firmness of the reinforcing cage 2 and prevent the reinforcing cage 2 and the permeation hole 11 from overlapping, which would result in weak welding of the reinforcing cage 2.

[0041] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, connecting bolts 31 are provided at the four corners of the top of the connecting skirt 3 of this utility model. When the two partition frames 1 are close to each other, the connecting skirts 3 on the sides of the two partition frames 1 are connected and fixed by the connecting bolts 31 and fasteners, so that the two partition frames 1 form a whole, and the distance between the two partition frames 1 is equal. This avoids the floor not becoming a whole after the concrete is poured.

[0042] like Figure 5 As shown, in some embodiments, the fastener of this utility model includes a connecting piece 5 and a fixing nut 6. The connecting piece 5 is a metal connecting piece. The connecting piece 5 is sleeved on two adjacent connecting bolts 31, connecting the two partition frames 1 together. The fixing nut 6 is threaded onto the connecting bolts 31 to fix and limit the connecting piece 5, thereby preventing the connecting piece 5 from detaching from the connecting bolts 31 and improving the firmness of the connection. Furthermore, the bolted connection method allows for easy installation even for non-professionals, improving the convenience of installation.

[0043] like Figures 1-3 As shown, in some embodiments, the surface of the connecting skirt 3 of this invention has a plurality of connecting holes 32 equidistantly spaced. When pouring concrete, the concrete permeates through the connecting holes 32 to enhance the adhesion between the concrete and the connecting skirt 3, thereby improving the strength of the concrete.

[0044] It should be noted that the connecting holes 32 on the two connecting skirts 3 can be connected using anchors. When the connecting bolts 31 and connecting pieces 5 cannot stably fix the partition frame 1, the connecting holes 32 on both sides can be used for auxiliary fixing to improve the stability of the fixation. Also, when the partition frame 1 is cut, one of the connecting bolts 31 may be missing. In this case, the connecting holes 32 can be used for auxiliary fixing.

[0045] like Figure 2 and Figure 3 As shown, in some embodiments, the bottom of the reinforcing frame 4 of this invention is provided with a cutting edge, which makes the stress point at the bottom of the reinforcing frame 4 more concentrated. This facilitates the insertion of the reinforcing frame 4 into the foundation when installing the partition frame 1.

[0046] The specific usage process of this utility model is as follows:

[0047] The partition frame 1 is laid flat on the foundation, and then two adjacent partition frames 1 are connected by connecting pieces 5 and fixing nuts 6, thus completing the predetermined floor slab. Pressure is applied to the top of the partition frame 1 manually or mechanically, causing the reinforcing frame 4 at the bottom of the partition frame 1 to penetrate into the foundation, improving the stability of the connection between the partition frame 1 and the foundation. Once all components are confirmed to be stable, concrete is poured into the interior of the partition frame 1 and between two adjacent partition frames 1. After pouring the concrete, it is compacted using vibratory equipment, and the top of the floor slab is smoothed. The floor slab is then gradually dried by keeping the concrete moist.

[0048] In summary, the anti-cracking control device for large-span factory floor construction of this utility model involves setting up multiple partition frames 1 spliced ​​and laid in the floor, and then pouring concrete into the partition frames 1 and the joints between the partition frames 1, so that the concrete is divided into several small pieces. When the concrete expands and contracts with temperature, the force between individual concrete pieces is small, thereby avoiding cracking and reducing the degree of cracking.

[0049] Meanwhile, the steel cage 2 is pre-welded into the partition frame 1, which can improve the strength of the concrete when pouring concrete and further prevent the concrete from cracking due to stress. It also eliminates the need for professional steelworkers to tie the steel on site, thus improving convenience.

[0050] This utility model provides a connecting skirt 3 at the bottom of the outer surface of the partition frame 1, and connecting bolts 31 at the four corners of the top of the connecting skirt 3. During assembly, the connecting piece 5 can be sleeved on two adjacent connecting bolts 31 and then fixed by fixing nuts 6, thus avoiding the impact force of concrete pouring, which could cause displacement and misalignment between the partition frames 1.

[0051] Meanwhile, the fixing method using connecting piece 5 and fixing nut 6 in conjunction with connecting bolt 31 is simple to operate, and the pre-set steel cage 2 inside the partition frame 1 allows non-professionals to quickly arrange and fix it, thus improving construction efficiency.

[0052] This utility model provides permeation holes 11 on the side of the partition frame 1 and connection holes 32 on the connecting skirt 3. When concrete is poured, the concrete will permeate into the permeation holes 11 and the connection holes 32, thereby making all the concrete in the partition frame 1 form a whole, thus improving the integrity and firmness of the concrete.

[0053] This utility model provides a reinforcing frame 4 at the bottom of the partition frame 1. When installing the partition frame 1, the reinforcing frame 4 can be inserted into the foundation, thereby supporting and limiting the partition frame 1 through the foundation, preventing the concrete from pushing the entire device to move when the concrete floor is poured.

[0054] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0055] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
