Description

Technical Field

[0001] This utility model relates to the field of building assembly technology, and in particular to a prefabricated floor slab, prefabricated building and prefabricated structure. Background Technology

[0002] In the large-scale construction of ordinary commercial housing in cities, prefabricated floor slabs can quickly assemble floor structures, shorten the construction cycle, and ensure the flatness and quality of the floor slabs, providing a good foundation for subsequent decoration and other work. For example, some large real estate development companies such as Vanke have adopted prefabricated floor slabs in many residential projects.

[0003] A search revealed Chinese Patent Publication No. CN220247333U, which discloses a prefabricated floor slab, comprising a high-strength prestressed concrete slab body, several concrete ribs, several truss reinforcing bars, and a structural steel mesh. The high-strength prestressed concrete slab body is a horizontally arranged concrete flat plate. The concrete ribs are located on the upper surface of the high-strength prestressed concrete slab. The structural steel mesh is a planar mesh structure, positioned above the high-strength prestressed concrete slab body and passing through the side surfaces of the concrete ribs. The truss reinforcing bars are positioned above the slab body, interlaced between the concrete ribs, and above the structural steel mesh. The fixing parts of the truss reinforcing bars clamp the transverse reinforcing bars of the structural steel mesh. This utility model improves the overall integrity of the device through the rib structure. The stability of the truss structure is greatly improved through its connection with the reinforcing rib structure, avoiding the possibility of deformation of the truss during storage and subsequent failure. The combined use of truss and rib structures balances lightweight design and strength.

[0004] The patent description mentions that "the truss reinforcement includes several first cross supports, several second cross supports, a pair of stabilizing bars and the truss reinforcement body". When the spacing between the reinforcing bars is too small and cannot be adjusted, it will bring great difficulties to the pouring and vibration of concrete. The concrete is difficult to fill the gaps between the reinforcing bars smoothly, which can easily lead to quality defects such as honeycomb and pitting, reducing the density and integrity of the concrete. For example, in some complex-shaped prefabricated floor slabs, the spacing between the reinforcing bars may lead to the concrete not being able to be poured fully to the corners. In view of the above problems, a prefabricated floor slab, a prefabricated building and a prefabricated structure are proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a prefabricated building floor slab, which aims to improve the problem that some existing devices cannot adjust the spacing between steel bars.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A prefabricated floor slab includes a non-removable bottom formwork, a plurality of truss steel bars are fixedly connected to the top of the non-removable bottom formwork, a structural steel mesh is fixedly connected to the top of the truss steel bars, a balancing mechanism is fixedly connected to the outer cross intersection of the structural steel mesh, and a spacing adjustment mechanism is fixedly connected to the steel mesh of the structural steel mesh.

[0008] The spacing adjustment mechanism includes a collar, an adjusting rod fixedly connected to the outside of the collar, multiple slots on the outside of the adjusting rod, a clamping assembly slidably connected to the other end of the adjusting rod, and the collar fixedly connected to the steel mesh of the structural steel mesh.

[0009] The above solution allows the bottom formwork to support the upper structure without needing to be removed. The truss reinforcement securely connects the upper and lower sections, enhancing overall strength. The structural steel mesh is a crucial component, with a balancing mechanism at its intersections ensuring stability. The mesh spacing adjustment mechanism, through the coordinated action of collars, adjusting rods, and clamping components, allows for spacing adjustments as needed to adapt to different construction requirements.

[0010] As a further description of the above technical solution:

[0011] The clamping assembly includes an adjusting sleeve, and a clamping rod is slidably connected to the outside of the adjusting sleeve. The outside of the adjusting sleeve slides outside the adjusting rod.

[0012] With the above method, the adjusting sleeve can slide smoothly outside the adjusting rod, facilitating position adjustment as needed. The locking rod can also slide flexibly outside the adjusting sleeve. When the adjusting sleeve reaches the appropriate position, the adjusting sleeve can be firmly locked by sliding the locking rod and engaging it into the locking groove of the adjusting rod, thereby accurately fixing the spacing of the structural steel mesh and ensuring the construction quality of the floor slab.

[0013] As a further description of the above technical solution:

[0014] The balancing mechanism includes a balancing cross cylinder, the bottom of which is fixedly connected to a support rod, and the outside of which is fixedly connected to the outer cross intersection of the structural steel mesh.

[0015] The above design features a uniquely shaped balancing cross tube, positioned at the outer cross intersection of the structural steel mesh and firmly fixed above. Its bottom is connected to a support rod that extends vertically downwards, steadily supporting the balancing cross tube. During construction, the balancing cross tube, in conjunction with the support rod, distributes pressure, ensuring uniform stress on the steel mesh, improving the overall stability of the floor slab, and guaranteeing the safety of the building structure.

[0016] As a further description of the above technical solution:

[0017] The outer side of the adjusting sleeve contacts the outer side of the collar, and the outer side of the locking rod engages with the locking groove;

[0018] Through the above scheme, in the spacing adjustment mechanism of the prefabricated floor slab, the adjusting sleeve and the collar are in close contact, ensuring the stability of their connection. When it is necessary to adjust the spacing of the structural steel mesh, the adjustable sleeve can be slidably moved on the adjusting rod. After determining the appropriate position, the locking rod is slid along the adjusting sleeve, precisely locking it into the locking groove of the adjusting rod, thereby firmly locking the spacing and providing precise structural support for the floor slab construction.

[0019] As a further description of the above technical solution:

[0020] The structural steel mesh is arranged above the non-removable bottom formwork in a manner parallel to the non-removable bottom formwork, with the structural steel mesh and the non-removable bottom formwork spaced apart;

[0021] Through the above solution

[0022] As a further description of the above technical solution:

[0023] Multiple structural steel meshes are disposed above the truss reinforcement, and the bottom of the truss reinforcement passes through the structural steel meshes and is connected to the non-removable bottom formwork;

[0024] Through the above scheme, the structural steel mesh plays a crucial supporting role. It is precisely arranged above the formwork, strictly parallel to the bottom formwork that does not need to be removed, with the two spaced out in an orderly manner. This layout not only ensures that the structural steel mesh fully performs its reinforcing function, but also leaves reasonable space for material filling and vibration during concrete pouring and other processes, comprehensively guaranteeing the stability of the floor slab structure and the smooth progress of construction.

[0025] As a further description of the above technical solution:

[0026] The prefabricated building includes the prefabricated floor slabs of the building;

[0027] The above solution, based on the bottom formwork without the need to remove it, combined with truss reinforcement, structural steel mesh and a variety of sophisticated components, significantly improves the overall structural stability, simplifies the construction process, and speeds up construction, bringing a new, efficient and high-quality solution to the construction industry.

[0028] As a further description of the above technical solution:

[0029] The prefabricated structure includes the prefabricated floor slabs of the building.

[0030] The above-mentioned scheme consists of a bottom formwork that does not need to be removed, truss reinforcement, and structural steel mesh. Through clever combination, it ensures good structural strength. When integrated into prefabricated structures, it not only improves overall stability but also significantly shortens the construction period, optimizes the construction process, and achieves efficient and reliable construction goals.

[0031] This utility model has the following beneficial effects:

[0032] In this invention, two collars are first installed on the outside of the structural steel mesh to provide a mounting base for the spacing adjustment mechanism. During operation, the locking rod is pulled out to release the fixing restriction on the adjustment rod. At this time, the adjustment rod can move flexibly inside the adjustment sleeve, making it convenient to adjust the position according to actual needs. When the steel mesh spacing is adjusted to a suitable size, the locking rod is reinserted to make it tightly locked with the locking groove opened on the outside of the adjustment rod, thereby fixing the adjustment rod in the current position and finally achieving precise adjustment of the steel mesh spacing.

[0033] In this invention, a balancing cross cylinder is first installed at the cross intersection of the structural steel mesh. The balancing cross cylinder, by virtue of its own structural characteristics, can provide stable support for the entire structural steel mesh. At the same time, a support rod is installed on the bottom template that does not need to be removed, so that it works in conjunction with the balancing cross cylinder. Through the method of upper and lower support, the structural steel mesh is balanced and stable. Attached Figure Description

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Reference Figures 1 to 3 This utility model provides an embodiment of a prefabricated building floor slab, including a non-removable bottom formwork 1. The surface of the non-removable bottom formwork 1 is smooth and flat, which can effectively reduce cement slurry leakage during concrete pouring and ensure the quality of concrete forming. The non-removable bottom formwork 1 also has good fireproof, moisture-proof, and sound insulation properties, which can improve the overall performance of the floor slab. Multiple truss steel bars 2 are fixedly connected to the top of the non-removable bottom formwork 1. The truss steel bars 2 play an important role in force transmission in the floor slab structure, transferring the load borne by the structural steel mesh 3 to the non-removable bottom formwork 1, and then distributing it to the entire floor slab support system. The top of the truss steel bars 2 is fixedly connected to the structural steel mesh 3, which is composed of multiple transverse and longitudinal steel bars woven together. Steel bars are often used in parts where the bond strength between the steel bars and concrete is not high.

[0042] Specifically, the non-removable bottom formwork 1 is the foundation. Its smooth surface effectively reduces cement slurry leakage during concrete pouring, ensuring molding quality, and also possesses fireproof, moisture-proof, and sound-insulating properties, improving the overall performance of the floor slab. During installation, the non-removable bottom formwork 1 is first placed in position, and then multiple truss reinforcing bars 2 are fixed on top of it. The truss reinforcing bars 2 are crucial in the floor slab structure, responsible for transferring the load borne by the structural steel mesh 3 to the non-removable bottom formwork 1, and then distributing it throughout the entire support system. Finally, a structural steel mesh 3, composed of multiple transverse and longitudinal reinforcing bars woven together, is connected to the top of the truss reinforcing bars 2. This steel reinforcement arrangement is often used in areas where the bond strength between the steel reinforcement and concrete is not critical, thus constructing a complete prefabricated floor slab structure.

[0043] The structural steel mesh 3 is arranged above the non-removable bottom formwork 1 in a manner parallel to it. The structural steel mesh 3 is spaced apart from the non-removable bottom formwork 1. Multiple structural steel meshes 3 are arranged above the truss steel bars 2, and the bottom of the truss steel bars 2 passes through the structural steel mesh 3 and is connected to the non-removable bottom formwork 1. A balancing mechanism 4 is fixedly connected at the outer cross intersection of the structural steel mesh 3. The balancing mechanism 4 includes a balancing cross cylinder 401. The balancing cross cylinder 401 is designed as a cross-shaped cylinder structure with a hollow interior and uniform wall thickness around it, depending on the actual stress conditions.

[0044] Specifically, the non-removable bottom formwork 1 is first laid in place. Then, the structural steel mesh 3 is arranged parallel to each other above the non-removable bottom formwork 1, with intervals between them. Multiple sets of structural steel mesh 3 are positioned above the truss reinforcement 2, with the bottom of the truss reinforcement 2 passing through the structural steel mesh 3 and connecting to the non-removable bottom formwork 1, thus establishing the basic framework. Next, a balancing mechanism 4 is installed at the external cross intersection of the structural steel mesh 3. The core component of the balancing mechanism 4, the balancing cross cylinder 401, has a cross-shaped cylindrical structure with a hollow interior. The cylinder wall thickness is uniformly designed according to the actual stress conditions, thereby ensuring that the structural steel mesh 3 is subjected to balanced forces in all directions, improving the stability and reliability of the overall structure.

[0045] On the top and sides of the balancing cross cylinder 401, there are installation structures for connecting with the structural steel mesh 3, such as welding bosses and bolt holes, to ensure a firm and reliable connection with the steel mesh. The bottom of the balancing cross cylinder 401 is fixedly connected to a support rod 402. The diameter of the support rod 402 is designed according to the size of the balancing cross cylinder 401 and the load it bears. The length of the support rod 402 is determined according to the spacing between the structural steel mesh 3 and the bottom template 1 that can be removed, as well as the installation height of the balancing cross cylinder 401, to ensure that it can provide effective support between the structural steel mesh 3 and the bottom template 1 that can be removed. The external fixed connection of the balancing cross cylinder 401 is at the external cross intersection of the structural steel mesh 3. The steel mesh of the structural steel mesh 3 is fixedly connected to a spacing adjustment mechanism 5.

[0046] Specifically, firstly, welding bosses, bolt holes, and other installation structures are installed on the top and sides of the balancing cross cylinder 401, and it is fixed to the outer cross intersection of the structural steel mesh 3 to ensure a firm connection. Next, based on the dimensions of the balancing cross cylinder 401, its load-bearing capacity, the spacing between the structural steel mesh 3 and the non-removable bottom formwork 1, and the installation height of the balancing cross cylinder 401, the diameter and length of the support rod 402 are designed and determined. Then, the support rod 402 is fixed to the bottom of the balancing cross cylinder 401, so that it can effectively support the structural steel mesh 3 and the non-removable bottom formwork 1. Finally, the spacing adjustment mechanism 5 is installed at the steel mesh of the structural steel mesh 3, completing the key construction steps of the entire structure and ensuring structural stability and complete functionality.

[0047] Reference Figures 2 to 4The spacing adjustment mechanism 5 includes a collar 501. The inner wall of the collar 501 is finely polished to ensure a smooth surface, reducing friction with the reinforcing bars of the structural steel mesh 3 and ensuring smooth installation. Its inner diameter is precisely designed according to the diameter of the reinforcing bars of the structural steel mesh 3 to ensure a tight fit with the reinforcing bars and prevent loosening. An adjustment rod 502 is fixedly connected to the outside of the collar 501. Multiple slots 503 are evenly opened by machining. The slots 503 are rectangular or trapezoidal in shape, and their depth and width are precisely designed according to the dimensions of the rod 505 to ensure that the rod 505 can be tightly inserted into them for reliable positioning. Multiple slots 503 are opened on the outside of the adjustment rod 502. During the machining of the slots 503 on the adjustment rod 502, high-precision CNC machining equipment is used to ensure the dimensional and positional accuracy of the slots 503.

[0048] Specifically, firstly, the inner diameter of the collar 501 is precisely designed based on the diameter of the reinforcing bars in the structural steel mesh 3. Its inner wall is finely polished to ensure smooth installation onto the reinforcing bars and a tight fit to prevent loosening. Next, an adjusting rod 502 is mechanically connected to the outside of the collar 501. Multiple rectangular or trapezoidal slots 503 are evenly cut into the adjusting rod 502 using high-precision CNC machining equipment. The depth and width of these slots are precisely designed according to the dimensions of the clamping rod 505 to ensure a tight fit and reliable positioning. The entire process, through precise design and machining, ensures convenient installation and accurate positioning of the spacing adjustment mechanism 5.

[0049] The other end of the adjusting rod 502 is slidably connected to a clamping assembly, which includes an adjusting sleeve 504. The outer wall of the adjusting sleeve 504 is provided with a groove for installing the clamping rod 505. The size and precision of the groove are designed according to the size and sliding requirements of the clamping rod 505 to ensure that the clamping rod 505 can slide flexibly in the groove. The outside of the adjusting sleeve 504 contacts the outside of the collar 501, and the outside of the clamping rod 505 engages with the groove 503. The outside of the adjusting sleeve 504 is slidably connected to the clamping rod 505. The clamping rod 505 is designed with one end wedge-shaped to facilitate engagement into the groove 503, and the other end is designed with a handle or protrusion structure for easy operation, so that the operator can push the clamping rod 505 to perform engagement and disengagement operations.

[0050] Specifically, the outer wall of the adjusting sleeve 504 has a groove that matches the locking rod 505, ensuring that the locking rod 505 can slide flexibly. The outside of the adjusting sleeve 504 contacts the collar 501, serving a positioning function. During operation, the operator holds the end of the locking rod 505 with the handle or protrusion and pushes the locking rod 505 to slide within the groove of the adjusting sleeve 504. Because one end of the locking rod 505 is wedge-shaped, it can smoothly engage with the locking groove 503, achieving the locking function; the reverse operation allows for separation.

[0051] The outer side of the adjusting sleeve 504 slides outside the adjusting rod 502, and the outer side of the collar 501 is fixedly connected to the steel mesh of the structural steel mesh 3. The prefabricated building includes the prefabricated floor slab, and the prefabricated structure includes the prefabricated floor slab. In the prefabricated building, this prefabricated floor slab can be installed quickly, reducing on-site construction time and labor intensity, while improving the quality and stability of the floor slab.

[0052] Specifically, in the assembly process of prefabricated buildings, the collar 501 is first fixed to the steel mesh of the structural steel reinforcement 3, providing basic support for the subsequent installation of components. Next, the adjusting sleeve 504 is fitted over the adjusting rod 502, allowing it to slide smoothly for flexible adjustment of the relevant structure. The core prefabricated floor slab, thanks to its design advantages, enables rapid assembly, significantly shortening on-site construction time and reducing labor intensity. Simultaneously, the floor slab quality is improved, stability is enhanced, and the construction process and quality of prefabricated buildings are comprehensively optimized.

[0053] Working principle: To ensure the balance and stability of the structural steel mesh 3, a balance cross cylinder 401 is first installed at the cross intersection of the structural steel mesh 3. The balance cross cylinder 401, with its own structural characteristics, can provide stable support for the entire structural steel mesh 3. At the same time, the support rod 402 is installed on the non-removable bottom template 1, so that it works together with the balance cross cylinder 401. Through the upper and lower support, the balance and stability of the structural steel mesh 3 are achieved.

[0054] When adjusting the spacing of the reinforcing mesh 3, first install two collars 501 on the outside of the reinforcing mesh 3 to provide a base for the spacing adjustment mechanism. During operation, pull out the locking rod 505 to release the fixing restriction on the adjusting rod 502. At this time, the adjusting rod 502 can move flexibly inside the adjusting sleeve 504, making it easy to adjust its position according to actual needs. After the reinforcing mesh spacing is adjusted to a suitable size, reinsert the locking rod 505 so that it is tightly locked with the locking groove 503 on the outside of the adjusting rod 502, thereby fixing the adjusting rod 502 in the current position and finally achieving precise adjustment of the reinforcing mesh spacing.

[0055] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
