Description
Technical Field
[0001] The utility model belongs to the technical field of cast-in-place slab construction, and particularly relates to an adjustable support for a YJ non-removable bottom formwork steel bar truss floor slab based on a full hall support. Background Technique
[0002] In recent years, with the rapid progress of the construction industry, prefabricated buildings, as an efficient and environmentally friendly building form, have been widely promoted and applied. Prefabricated buildings are assembled at the construction site through prefabricated components, which not only significantly improves the construction efficiency, shortens the construction period, but also greatly reduces the resource consumption and environmental pollution during the construction process, meeting the green and low-carbon development trend of the modern construction industry.
[0003] In prefabricated buildings, the floor slab, as an important part of the floor structure, its performance and quality are directly related to the overall safety and service life of the building. Traditional floor slabs often have problems such as complex construction, large self-weight, the need to remove the formwork, and the easy generation of a large amount of construction waste. For this reason, the YJ non-removable bottom formwork steel bar truss floor slab (YJ slab) came into being. With its unique advantages, such as large stiffness, light self-weight, and the ability to directly carry out decoration without removing the bottom formwork, it effectively solves the above problems, greatly facilitates the construction operation, shortens the construction period, and reduces the cost.
[0004] However, in the actual construction process of the YJ non-removable bottom formwork steel bar truss floor slab, there are still some technical challenges. According to the construction method guided by the existing atlas, two vertical poles are set at each end of each YJ non-removable bottom formwork steel bar truss floor slab as temporary supports. Although this point-like support method is simple, the adjustment of each support point is relatively independent, making it difficult to ensure the consistency of the elevation and flatness between adjacent slabs, resulting in the need for cumbersome secondary adjustment work after laying, increasing the construction difficulty and labor cost. Summary of the Invention
[0005] Aiming at the problems existing in the prior art, the utility model provides an adjustable support for a YJ non-removable bottom formwork steel bar truss floor slab based on a full hall support, aiming to solve the problems that it is difficult to ensure the consistency of the elevation and flatness between adjacent slabs, resulting in the need for cumbersome secondary adjustment work after laying, increasing the construction difficulty and labor cost.
[0006] In order to solve the above technical problems, the utility model is realized through the following technical solutions:
[0007] An adjustable support for a YJ non-removable bottom formwork steel bar truss floor slab based on a full hall support, comprising a number of socketed frame vertical poles correspondingly connected to the side members of the full hall frame on the beam side. The upper end of the socketed frame vertical pole is connected with a height-adjustable jack. A horizontal member is placed on the height-adjustable jack. One end of the horizontal member is detachably connected to the corresponding side member of the full hall frame on the beam side. At least two horizontal wooden squares are orthogonally arranged on the horizontal member. A wooden formwork is laid on the horizontal wooden squares. The YJ non-removable bottom formwork steel bar truss floor slab is placed on the wooden formwork.
[0008] Further, the height-adjustable jack includes a screw rod inserted and threadedly connected to the upper end of the socketed frame vertical pole, and a supporting plate connected to the upper end of the screw rod.
[0009] Further, the length of the screw rod inserted into the socketed frame vertical pole is not less than 150 mm.
[0010] Further, the thickness of the supporting plate is not less than 5 mm.
[0011] Further, one end of the horizontal member is connected to the corresponding side member of the full hall frame on the beam side through a right-angle fastener.
[0012] Further, the width of the wooden formwork is not less than one-sixth of the length of the YJ non-removable bottom formwork steel bar truss floor slab.
[0013] Further, the thickness of the wooden formwork is 18 mm to 22 mm.
[0014] Further, the horizontal member is made of a steel pipe.
[0015] Compared with the prior art, the utility model has at least the following beneficial effects:
[0016] The adjustable support for the YJ non-removable bottom formwork steel bar truss floor slab based on the full hall support provided by the utility model utilizes the beam side members of the full hall frame on the beam side, adds the vertical rods of the disc buckle frame, and can conveniently adjust the height of the YJ non-removable bottom formwork steel bar truss floor slab through the height-adjustable jacks on the vertical rods of the disc buckle frame. Moreover, a horizontal member is arranged on each height-adjustable jack, horizontal wooden squares are orthogonally arranged in cooperation on multiple horizontal members, and wooden formworks are jointly laid on multiple horizontal wooden squares. The support for the YJ non-removable bottom formwork steel bar truss floor slab is realized through the wooden formworks, effectively solving the problems generated in the actual on-site construction of the YJ slab atlas. The point-like temporary support at the end of the YJ slab is changed to a strip-shaped support, increasing the support area and improving stability. After the strip-shaped formwork is leveled, the YJ slab is directly placed on it, not only solving the problem of difficult control of elevation and flatness in traditional construction, but also using the wooden formwork as a transition layer to solve the problem of excessive joint gap and insufficient sealing between the YJ slab and the beam side formwork in actual construction, improving the sealing performance at the joint, effectively preventing the occurrence of slurry leakage phenomenon, and improving the construction efficiency and quality. In summary, the utility model can achieve the consistency of elevation and flatness between adjacent slabs, avoid the cumbersome secondary adjustment work after laying, and reduce the construction difficulty and labor cost.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0022] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Apparently, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0023] An adjustable support for a YJ non-removable bottom formwork steel bar truss floor slab based on a full hall formwork is provided in an embodiment of the present utility model, aiming to overcome the problem of difficult control of elevation and flatness during the construction of the existing YJ non-removable bottom formwork steel bar truss floor slab. Combining Figure 1 and Figure 2 As shown, the adjustable support includes: a plurality of socketed formwork vertical poles 2 correspondingly connected to the side members 1 of the full hall formwork for the beam side. The upper end of the socketed formwork vertical pole 2 is connected with a height-adjustable jack 3. A horizontal member 4 is placed on the height-adjustable jack 3. One end of the horizontal member 4 is detachably connected to the corresponding side member 1 of the full hall formwork for the beam side. At least two horizontal wooden squares 5 are orthogonally arranged on the horizontal member 4. A wooden formwork 6 is laid on the horizontal wooden square 5. The YJ non-removable bottom formwork steel bar truss floor slab 7 is placed on the wooden formwork 6.
[0024] More specifically, the adjustable support mainly includes the following parts:
[0025] Socketed formwork vertical pole 2: A plurality of socketed formwork vertical poles 2, the number of which is determined according to actual needs, are correspondingly connected and arranged with the existing side members 1 of the full hall formwork for the beam side (i.e., the main support structure in traditional construction), and are mainly used for vertical force bearing. The socketed formwork vertical pole 2 adopts a socketed connection method, which is convenient for quick installation and disassembly, and has a stable and reliable structure.
[0026] Exemplarily, the diameter of the socketed formwork vertical pole 2 is 48.3 mm, and the step distance is 1500 mm. The socketed formwork vertical poles 2 are longitudinally arranged along the beam direction. The spacing of the socketed formwork vertical poles 2 in the longitudinal direction of the beam is 900 mm, and transversely, they are arranged at both ends of the YJ plate. Two socketed formwork vertical poles 2 are arranged at each end of each YJ plate.
[0027] Height-adjustable jack 3: A height-adjustable jack 3 is connected to the upper end of each socketed formwork vertical pole 2. The height-adjustable jack 3 realizes precise height adjustment through a thread or other adjustment mechanisms to ensure that the YJ non-removable bottom formwork steel bar truss floor slabs 7 at different positions are on the same horizontal plane, improving the construction accuracy.
[0028] Horizontal member 4: A horizontal member 4 is placed on the height-adjustable jack 3. One end of the horizontal member 4 is firmly connected to the side member 1 of the full hall formwork corresponding to the beam side by bolts, buckles or other detachable connection methods, and the other end is freely placed on the jack, forming a stable support platform. The direction of the horizontal member 4 is parallel to the direction of the YJ plate.
[0029] Horizontal wooden square 5: At least two horizontal wooden squares 5 are orthogonally arranged on the horizontal member 4. The wooden squares are fixed to each other by nails, screws or other fasteners to enhance the flatness and load-bearing capacity of the support surface. Exemplarily, the wooden square adopts a specification of 50mm×100mm.
[0030] Wood formwork 6: A layer of wood formwork 6 is laid on the horizontal wooden square 5. The wood formwork 6 should be flat and free of warping to provide a uniform support surface for the YJ non-removable bottom formwork steel bar truss floor slab 7. Finally, the YJ non-removable bottom formwork steel bar truss floor slab 7 is placed on the wood formwork 6 for subsequent construction processes such as concrete pouring.
[0031] Through the adjustable support for the YJ non-removable bottom formwork steel bar truss floor slab based on the full hall formwork provided by this embodiment, with the help of the side member 1 of the full hall formwork for the beam side, the disc buckle frame vertical rod 2 is added. The height of the YJ non-removable bottom formwork steel bar truss floor slab 7 can be conveniently adjusted through the height-adjustable jack 3 on the disc buckle frame vertical rod 2. And a horizontal member 4 is arranged on each height-adjustable jack 3. Multiple horizontal members 4 are orthogonally arranged with horizontal wooden squares 5 in cooperation. A wood formwork 6 is jointly laid on multiple horizontal wooden squares 5. The YJ non-removable bottom formwork steel bar truss floor slab 7 is supported through the wood formwork 6, effectively solving the problems generated in the actual on-site construction of the YJ plate atlas. The point-like temporary support at the end of the YJ plate is changed to a strip-like support, increasing the support area and improving stability. After the strip-shaped formwork is leveled, the YJ plate is directly placed on it, not only solving the problem of difficult control of elevation and flatness in traditional construction, but also using the wood formwork 6 as a transition layer to solve the problem of excessive joint gap and insufficient sealing between the YJ plate and the beam side formwork in actual construction, improving the sealing performance at the joint, effectively preventing the occurrence of slurry leakage phenomenon, improving the construction efficiency and quality, and the adjustable support has a simple structure and is convenient to set up.
[0032] In a realizable manner, as Figure 1 shown, the height-adjustable jack 3 includes a screw rod inserted and threadedly connected to the upper end of the disc buckle frame vertical rod 2, and a support plate connected to the upper end of the screw rod. Specifically, the height-adjustable jack 3 includes a screw rod and a support plate. The screw rod is inserted and threadedly connected to the upper end of the disc buckle frame vertical rod 2. The design of the screw rod enables it to freely rotate and move up and down along the axial direction of the disc buckle frame vertical rod 2, thereby realizing the adjustment of the height of the jack. The support plate is connected to the upper end of the screw rod to form a stable support platform. The surface of the support plate is flat and is used to place the subsequent horizontal member 4 to ensure the stable placement of the floor slab.
[0033] In one embodiment, the height-adjustable top support 3 can adjust the height of the support through a screw and a nut, so as to achieve the effect of adjusting the elevation of the YJ plate. The outer diameter of the screw shall not be less than 36 mm, the screwed length of the screw and the nut shall not be less than 5 threads, and the thickness of the nut shall not be less than 30 mm. The length inserted into the disc buckle frame vertical rod 2 shall not be less than 150 mm. This regulation ensures that the connection between the screw and the disc buckle frame vertical rod is firm enough to prevent loosening or slipping when adjusting the height or bearing the load. The longer insertion length provides a larger contact area and stronger friction force, thus improving the stability and safety of the overall structure. The thickness of the support plate shall not be less than 5 mm, and the deformation shall not be greater than 1 mm. This regulation ensures that the support plate has sufficient strength and stiffness to bear the weight of the floor formwork and various loads that may occur during the construction process, and can reduce the risk of support failure caused by deformation or rupture, thus improving the construction quality and safety.
[0034] It should be noted that when selecting the material of the support plate, materials with good bearing capacity and durability should be preferred, such as high-quality steel plates or alloy materials. When installing the support plate, it should be ensured that it is flat and firmly connected to the screw, and the contact surface with the horizontal member or other support materials should be checked for close fit to avoid gaps or looseness.
[0035] In an implementable manner, as Figure 1 shown, one end of the horizontal member 4 is connected to the corresponding beam side by the full hall frame beam side member 1 through a right-angle fastener 8. This connection method is realized through the right-angle fastener 8, which not only enhances the stability of the overall structure but also ensures the effective support of the horizontal member in the horizontal direction.
[0036] It should be understood that the right-angle fastener 8 is a commonly used building connector, which is designed to firmly connect two mutually perpendicular members. When selecting the right-angle fastener, it should be ensured that its material is excellent, with high strength, corrosion resistance, and meets the requirements of relevant building standards. During installation, first, put one opening of the right-angle fastener 8 on the predetermined position of the horizontal member 4, and then align the other opening with the corresponding position of the beam side full hall frame beam side member 1. By rotating or tightening the bolts or nuts on the fastener, the two are tightly connected together.
[0037] Preferably, in order to ensure the strength and stability of the connection point, gaskets or reinforcement plates can be added at the contact parts between the right-angle fastener 8 and the members to disperse the stress and prevent local damage.
[0038] In one embodiment, the width of the wooden formwork 6 is not less than one-sixth of the length of the YJ non-removable bottom formwork steel bar truss floor slab 7. This design takes into account the stability during the construction process and the support efficiency of the formwork. For example, if the length of the floor slab is 6 meters, the minimum width of the wooden formwork should be 1 meter. In practical applications, to increase stability and redundancy, the width of the wooden formwork is usually slightly greater than this minimum value. Select suitable wood or artificial board as the material of the wooden formwork 6 to ensure that the selected material has sufficient strength and stiffness to withstand the loads and deformations during the construction process. When laying the wooden formwork 6 on the horizontal wooden square 5, ensure that the width of the formwork meets the requirements and is closely fitted with the horizontal wooden square without gaps. Nails, screws or other fasteners can be used to fix the formwork on the horizontal wooden square to prevent it from shifting or deforming during use.
[0039] Exemplarily, as Figure 2 shown, the width of the wooden formwork is 40 cm and it is continuously arranged, closely attached to the side formwork of the beam, arranged in a circular plate strip shape to form a plate strip support, providing a reliable plane for the YJ plate, increasing the support area and thus improving the stability.
[0040] In one embodiment, the thickness of the wooden formwork 6 is 18 mm to 22 mm. This range not only ensures that the formwork has sufficient load-bearing capacity and stiffness to support the YJ non-removable bottom formwork steel bar truss floor slab 7 and the concrete layer thereon, but also avoids the increased material cost and construction difficulty due to excessive thickness. Exemplarily, the thickness of the wooden formwork 6 is 20 mm.
[0041] Preferably, the horizontal member 4 is made of steel pipe. The steel pipe has high strength and good stiffness and can withstand large bending stress and shear stress. In the adjustable support, the horizontal member needs to bear the weight of the floor slab and the concrete layer thereon, as well as various dynamic loads during the construction process. The excellent mechanical properties of the steel pipe can ensure the stability and safety of the support system. The steel pipe is easy to process and connect, and can be cut, welded or threaded according to actual needs, which makes it possible to quickly assemble and disassemble the support at the construction site and improves the construction efficiency.
[0042] Exemplarily, the horizontal steel pipe has a diameter of 48.3 mm and a wall thickness of 3.6 mm. One end is connected to the side of the beam with a right-angle fastener by the full hall frame side member 1 to play a stabilizing role. The force of the horizontal steel pipe is directly transmitted to the height-adjustable jack. The length of the horizontal steel pipe is not less than 400 mm.
