DETAILED DESCRIPTION

[0022] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] like Figure 1 and Figure 2 As shown, the utility model provides a roof floating board formwork structure 1, which is installed on the shear wall 2. The roof floating board formwork structure 1 includes multiple support bases 11, multiple channel steels 12, plywood 13 and roof floating boards 14. The support base 11 includes a first end face 111 and a second end face 112. The multiple support bases 11 are sequentially arranged on the shear wall 2 along a first direction at intervals to adapt to the width and support requirements of the floating board. The first end face 111 of the support base 11 is fixedly connected to the shear wall 2 as the basic support unit of the entire structure; the first end face 111 and the second end face 112 are arranged vertically to ensure that the support base The seat 11 can be firmly attached to and anchored on the shear wall 2, so as to effectively transfer the load to the main structure of the building. The channel steels 12 are arranged on the support base 11 at intervals along the second direction in sequence, so as to bear the load generated by the formwork and pouring concrete, and ensure the overall rigidity and stability of the formwork system. The second end face 112 of the support base 11 is fixedly connected to the channel steel 12, and the plywood 13 is laid on the side of the channel steel 12 away from the second end face 112 to form a spatial boundary for pouring concrete. The roof floating board 14 is cast and formed on the side of the plywood 13 away from the channel steel 12, so as to effectively share part of the load of the building.

[0024] Based on the above structure, the support base 11 is directly installed on the shear wall 2, avoiding the cantilevered I-beam method used in the prior art, simplifying the hoisting and installation process of large components, and reducing the safety risks and manpower and material investment caused by hoisting I-beams. Secondly, by arranging the channel steels 12 in an orderly manner on the support base 11 and laying plywood 13 as a template, a modular and standardized formwork method is formed, which is easy to install and disassemble quickly and can be recycled, saving construction time and cost, and also improving construction efficiency and safety; in addition, the roof floating board formwork structure 1 directly utilizes the shear wall 2, strengthens the connection with the main structure, enhances the overall structural stability, and thus reduces the safety hazards caused by the instability of the support system.

[0025] It should be noted that the first direction is along the length direction of the shear wall 2 , and the second direction is along the width direction of the shear wall 2 .

[0026] Furthermore, the support base 11 also includes a plurality of reinforcing plates 113, which are sequentially arranged on the support base 11 at intervals along the first direction, and the reinforcing plates 113 are respectively connected to the first end surface 111 and the second end surface 112, thereby effectively reinforcing the support base 11 on two vertical surfaces. In this embodiment, the reinforcing plates 113 can disperse and balance the stress on the support base 11 through the above-mentioned method, improve the bearing capacity of the support base 11 for the upper channel steel 12, plywood 13 and roof floating board 14, and prevent deformation or damage caused by local excessive force or vibration.

[0027] Furthermore, it also includes a plurality of screw connectors 15, a plurality of first mounting holes 1111 are provided on the first end face 111, and a corresponding first mounting hole 1111 is provided at the interval between two adjacent reinforcing plates 113, and the corresponding screw connector 15 passes through the first mounting hole 1111 and is fixedly connected to the shear wall 2, thereby improving the connection strength and stability between the support base 11 and the shear wall 2; similarly, a plurality of second mounting holes 1121 are provided on the second end face 112, and a corresponding second mounting hole 1121 is provided at the interval between two adjacent reinforcing plates 113, and the corresponding screw connector 15 passes through the second mounting hole 1121 and is fixedly connected to the channel steel 12, thereby ensuring that the channel steel 12 is accurately and firmly positioned on the support base 11.

[0028] Based on the above structure, the present embodiment forms a mechanical lock between the support base 11 and the shear wall 2 and the channel steel 12 by adding the screw connector 15, which greatly enhances the bearing capacity and pull-out resistance of the connection part. In addition, the screw connector 15 can effectively prevent the support base 11 from sliding or loosening when subjected to external force, thereby ensuring the stability of the overall structure during construction.

[0029] Furthermore, the reinforcing plate 113 is triangular in shape, and can transmit and disperse the load in all directions, disperse and guide the force applied to the support base 11 to other supporting parts of the base, avoid stress concentration, increase the bearing capacity of the support base 11, and effectively improve the structural stability of the support base 11.

[0030] Furthermore, there are three reinforcing plates 113, which are equidistantly arranged on the support base 11 along the first direction, ensuring that the load borne by the support base 11 in the first direction is evenly distributed, avoiding local overload and structural damage due to load concentration at a certain point.

[0031] Furthermore, the spacing between two adjacent support bases 11 is no more than 500 mm, so as to better evenly distribute the load from the upper channel steel 12, plywood 13 and roof floating board 14, and avoid damage caused by local support overload. In addition, the support bases 11 arranged at this spacing can improve the lateral stiffness of the entire structure, reduce structural deformation caused by vibration, wind load or other dynamic factors, and effectively reduce the degree of freedom between support points, reduce the risk of instability of the support structure during construction, and thus improve the safety factor of the entire construction process.

[0032] like Figure 3 As shown, the channel steel 12 includes a third end face 121, a fourth end face 122 and a fifth end face 123, and the third end face 121, the fourth end face 122 and the fifth end face 123 are connected in sequence. The third end face 121 and the fifth end face 123 serve as side wing faces of the channel steel 12, and the two are arranged parallel to each other. The fourth end face 122 is respectively perpendicular to the third end face 121 and the fifth end face 123, and plays a major load-bearing and connecting role, so that the channel steel 12 has a higher bending resistance. The third end face 121 is provided with a screw hole 1211 for fixing to the second end face 112, which is used to connect to the second end face 112 through fasteners such as bolts and nuts, so as to achieve a firm splicing of the channel steel 12 with other structures, ensure that the predetermined load is borne in the entire structure, and complete the effective support of the roof floating plate 14.

[0033] Furthermore, the spacing between two adjacent channel steels 12 is no more than 300 mm. This spacing setting can make the structure more compact, thereby enhancing the lateral stiffness and stability of the overall structure, reducing deformation and vibration, and ensuring that the load is more evenly distributed to each channel steel 12, especially when subjected to dynamic loads or seismic loads, thereby avoiding premature fatigue or damage to a single channel steel 12 due to excessive concentrated loads, thereby improving safety.

[0034] Furthermore, the thickness of the plywood 13 is 18 mm, which has a stronger bearing capacity. Its thickness can ensure sufficient rigidity and strength during the pouring and curing process, thereby ensuring the quality of the concrete structure.

[0035] Furthermore, the screw connection 15 is an expansion bolt, which does not need to be welded or embedded. It only requires drilling holes in the base material in advance, inserting the expansion bolt set into the hole, and tightening the nut to achieve quick installation. At the same time, it can ensure that the fixed objects are not easy to fall off under normal load conditions, thereby improving the safety of the project.

[0036] In summary, the embodiment of the utility model provides a roof floating board formwork structure 1, which directly installs the support base 11 on the shear wall 2, avoiding the method of cantilevering I-beams used in the prior art, simplifying the lifting and installation process of large components, and reducing the safety risks and manpower and material investment caused by lifting I-beams. Secondly, by orderly arranging channel steels 12 on the support base 11 and laying plywood 13 as a template, a modular and standardized formwork method is formed, which is easy to install and disassemble quickly, saving construction time and cost, and also improving construction efficiency and safety; in addition, the roof floating board formwork structure 1 directly utilizes the shear wall 2, strengthens the connection with the main structure, enhances the overall structural stability, and thus reduces the safety hazards caused by the instability of the support system.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
