The present application can also be implemented or applied by other different specific embodiments, and each detail in the specification can be modified or changed based on different viewpoints and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, and are not intended to limit the protection scope of the present application.

[0036] The present application provides a hollow prestressed floor structure, which comprises a plurality of hollow prestressed floor slabs arranged in parallel and connected by a plurality of connecting pieces. Figure 1 and Figure 2As shown, the hollow prestressed floor structure comprises a positioning unit, a filling box 1, a plurality of first horizontal tension members 2, a plurality of second horizontal tension members 3 and a plurality of vertical tension members 4; a plurality of accommodating spaces are arranged in the positioning unit; the filling box 1 is arranged in the accommodating space; a plurality of first horizontal tension members 2 are arranged on the left and right sides of the filling box 1 along the horizontal plane and are assembled with the positioning unit; a plurality of second horizontal tension members 3 are arranged on the front and back sides of the filling box 1 along the horizontal plane and are assembled with the positioning unit; a plurality of vertical tension members 4 are arranged on the upper and lower sides of the filling box 1 along the vertical plane and are assembled with the positioning unit; the first horizontal tension members 2, the second horizontal tension members 3 and the vertical tension members 4 are orthogonally distributed two by two and are arranged in mutual staggered positions.

[0037] Specifically, the accommodating space is used to accommodate the filling box 1, and after the filling box 1 is arranged in the accommodating space, the positioning unit is arranged to surround the filling box 1 from the periphery; the first horizontal tension members 2 are arranged along the horizontal plane and extend to the left and right sides of the filling box 1, so that the two ends of the first horizontal tension members 2 can be assembled with the positioning unit along the left-right horizontal direction; the second horizontal tension members 3 are arranged along the horizontal plane and extend to the front and back sides of the filling box 1, so that the two ends of the second horizontal tension members 3 can be assembled with the positioning unit along the front-back horizontal direction; the vertical tension members 4 are arranged along the vertical plane and extend to the upper and lower sides of the filling box 1, so that the two ends of the vertical tension members 4 can be assembled with the positioning unit along the up-down vertical direction, thereby positioning the filling box 1.

[0038] In the present application, by arranging a plurality of direction tension members and assembling the corresponding tension members with the positioning unit, the filling box 1 can be fixed in the horizontal and vertical directions, thereby achieving multi-directional control of anti-floating and ensuring that the filling box 1 does not produce anti-floating during the concrete pouring process.

[0039] In an embodiment of the present application, the distance between the first horizontal tension members 2 and the second horizontal tension members 3 and the top surface of the filling box 1 is less than 1 / 2 of the height of the filling box 1.

[0040] Specifically, the horizontal plane where the first horizontal tension members 2 are located and the horizontal plane where the second horizontal tension members 3 are located are close to the upper half of the filling box 1, which can provide more effective lateral stability, form a horizontal support network and ensure that the filling box 1 does not tilt or rotate due to the upward force, thereby maintaining the stable position of the filling box 1 during the concrete pouring.

[0041] Meanwhile, the filling box 1 will have a floating tendency during the concrete pouring process due to the buoyancy. Since the action point of the buoyancy is close to the central part of the filling box 1, the first horizontal tension member 2 and the second horizontal tension member 3 arranged close to the upper half can more effectively resist the floating tendency, thereby limiting the displacement of the filling box 1.

[0042] In an embodiment of the present application, the filling box 1 is provided with a first horizontal through hole 11, a second horizontal through hole (not shown in the figure) and a vertical through hole (not shown in the figure); the first horizontal tension member 2 passes through the first horizontal through hole 11 and extends out of the filling box 1 at both ends; the second horizontal tension member 3 passes through the second horizontal through hole and extends out of the filling box 1 at both ends; and the vertical tension member 4 passes through the vertical through hole and extends out of the filling box 1 at both ends.

[0043] In the embodiment, the first horizontal through hole 11 penetrates the filling box 1 from left to right in the horizontal direction, and the second horizontal through hole penetrates the filling box 1 from front to back in the horizontal direction, and the vertical through hole penetrates the filling box 1 from top to bottom in the vertical direction, so as to facilitate the installation of the first horizontal tension member 2, the second horizontal tension member 3 and the vertical tension member 4.

[0044] The first horizontal tension member 2, the second horizontal tension member 3 and the vertical tension member 4 all pass through the filling box 1, which increases the interference contact area between each tension member and the filling box 1, improves the tension effect of each tension member on the filling box 1, and thus improves the control effect of each tension member on the filling box 1.

[0045] In an embodiment of the present application, the hollow prestressed floor structure further comprises a first detachable sealing member, a second detachable sealing member and a third detachable sealing member; the first detachable sealing member cooperates with the first horizontal through hole 11, the second detachable sealing member cooperates with the second horizontal through hole, and the third detachable sealing member cooperates with the vertical through hole.

[0046] Specifically, each through hole has a corresponding detachable sealing member, so that after each through hole on the filling box 1 is prepared, the through hole can be sealed by the corresponding detachable sealing member to prevent rainwater from entering. When installing each tension member, each detachable sealing member is removed from the corresponding through hole, and the assembly of each tension member in the corresponding through hole can be performed.

[0047] In an embodiment of the present application, the first horizontal tension member 2 and the second horizontal tension member 3 are both two, and the distance between the two first horizontal tension members 2 is equal to the distance between the two second horizontal tension members 3.

[0048] In an embodiment of the present application, the distance between each of the two first horizontal tension members 2 and the front and rear edges of the filling box 1 is 1 / 5 to 1 / 4 of the front and rear width of the filling box 1.

[0049] Specifically, the first horizontal tension member 2 being too close to the edge of the filling box 1 can cause stress concentration on the edge of the filling box 1 when the first horizontal tension member 2 is under stress, which can cause structural weakness; being too far away can make it difficult to provide effective support; therefore, in the present embodiment, the distance between each of the two first horizontal tension members 2 and the front and rear edges of the filling box 1 is 1 / 5 to 1 / 4 of the front and rear width of the filling box 1.

[0050] The two first horizontal tension members 2 are symmetrically arranged to balance the horizontal anti-floating force applied to the filling box 1; such a symmetric arrangement can stabilize the posture of the filling box 1 and avoid uneven stress or rotation tendency during the concrete pouring process.

[0051] Similarly, the distance between each of the two second horizontal tension members 3 and the left and right edges of the filling box 1 is 1 / 5 to 1 / 4 of the left and right width of the filling box 1, thereby avoiding stress concentration on the edge of the filling box 1 when the second horizontal tension member 3 is under stress while ensuring effective support. The two second horizontal tension members 3 are symmetrically arranged to balance the horizontal anti-floating force applied to the filling box 1; such a symmetric arrangement can stabilize the posture of the filling box 1 and avoid uneven stress or rotation tendency during the concrete pouring process.

[0052] The first horizontal tension member 2 and the second horizontal tension member are mainly used to resist the horizontal floating force generated by the filling box 1 during the concrete pouring process; in the horizontal direction (front and rear or left and right), since the floating force of the filling box 1 is usually uniformly distributed, and the direction of the floating force is generally along one of the two directions on the horizontal plane; therefore, arranging two first horizontal tension members 2 in the horizontal left and right direction and two second horizontal tension members 3 in the horizontal front and rear direction can provide balanced support force for the filling box 1.

[0053] In an embodiment of the present application, the vertical tension member 4 is four in number to ensure that the floating force of the filling box 1 can be effectively constrained in four directions; such a four-corner support can prevent the filling box 1 from rotating or displacing, while ensuring that the floating force can be uniformly and stably dispersed, reducing the risk of structural instability. At the same time, since the vertical floating force can be more concentrated during the pouring process, compared to the first horizontal tension member 2 and the second horizontal tension member 3, the number of vertical tension members 4 is increased in the present embodiment, which can more effectively disperse the floating force, ensure that the filling box 1 does not float or displace, and enhance the structural stability.

[0054] The four vertical tension members 4 can form a symmetrical distribution, ensuring that the buoyancy in each direction can be effectively controlled, thereby avoiding the local instability caused by the concentrated action of the buoyancy. Each vertical tension member 4 bears less pressure and shares the burden of the buoyancy, avoiding excessive burden of a single vertical tension member 4.

[0055] In an embodiment of the present application, the four vertical tension members 4 are arranged in a square distribution and coincide with the anti-floating pull joints of the filling box 1, which can ensure that the stress between the four vertical tension members 4 is uniform, avoiding that a certain area bears excessive buoyancy, leading to instability or deformation of the structure.

[0056] In the square layout, the distance between each adjacent two vertical tension members 4 is equal, which helps to maintain the stability of the structure. Since the direction and strength of the force of each vertical tension member 4 are close, this uniform distribution design can prevent any vertical tension member 4 from failing due to unbalanced stress. In addition, the square structure configuration provides stronger stability because it ensures that the vertical tension members 4 act together in multiple directions, dispersing the risk of buoyancy and avoiding excessive stress concentration of the filling box 1 in any direction.

[0057] At the same time, the four vertical tension members 4 are arranged in a square, which can effectively control the buoyancy of the filling box 1 and maintain its position in the vertical direction not disturbed by the buoyancy. The square distribution forms a symmetrical support system at the four corners, ensuring balanced distribution of the buoyancy; this layout can more evenly constrain the buoyancy, thereby avoiding the filling box 1 from floating or becoming unstable during construction.

[0058] In an embodiment of the present application, the first horizontal tension member 2, the second horizontal tension member 3 and the vertical tension member 4 are all stainless steel tension members made of stainless steel non-combustible material.

[0059] In an embodiment of the present application, the hollow prestressed floor structure further comprises a connecting member 5, which corresponds to the vertical tension member 4 one-to-one and is arranged at the bottom of the vertical tension member 4.

[0060] Specifically, the connecting member 5 is four, and the four connecting members 5 correspond to the vertical tension members 4 one-to-one and are used to cooperate with the positioning unit to fix the four vertical tension members 4 and at the same time control the bottom plate concrete pouring thickness of the hollow prestressed floor structure.

[0061] In an embodiment of the present application, the connecting member 5 comprises a stainless steel rivet.

[0062] The positioning unit includes a top positioning component, a bottom positioning component 100, and a plurality of ribs 200; the bottom positioning component 100 is located below the top positioning component and has a cavity between it and the top positioning component; the plurality of ribs 200 are located in the cavity and divide the cavity into a plurality of receiving spaces.

[0063] The upper end of the vertical tension member 4 is assembled with the top positioning component, the lower end of the vertical tension member 4 is assembled with the bottom positioning component 100, and both ends of the first horizontal tension member 2 and both ends of the second horizontal tension member 3 are respectively assembled with the corresponding rib beam 200, thereby positioning the filling box 1.

[0064] like Figure 3 As shown, the bottom positioning component 100 includes a disc-buckle formwork support 101 and a template 102; the template 102 is disposed above the disc-buckle formwork support 101; the template 102 is provided with mounting holes, which correspond one-to-one with the connecting member 5 and cooperate with each other. The top positioning component includes a rib.

[0065] Specifically, the following construction process is adopted when constructing the hollow prestressed floor slab structure:

[0066] The disc-lock formwork frame is erected according to the specifications of 600*900*1500, and the poles are pushed back under the rib beams as the rib beams exceed the limit. The columns below are poured in sections and simultaneously.

[0067] The template is laid out, and the template is arched to a height of 1 / 1000 to 3 / 1000. During the setting process, a level is used to mark the arching position in advance, and then the template is laid out according to the elevation.

[0068] Lay out the lines in advance, determine the tie points for fixing the filling box, and mark them on the template. After the tie points on the template are firmly fixed with fixed stainless steel nails, the installation is completed and the next step is carried out.

[0069] With the longitudinal reinforcement bars at the bottom and the transverse reinforcement bars at the top, begin tying the rib beam reinforcement bars. The bottom reinforcement bars of the rib beam reinforcement bars are located below the bottom reinforcement bars of the bottom slab. Complete the tying of the rib beam reinforcement bars one by one according to the procedure.

[0071] After the rib beam and the bottom plate steel bar binding is completed, the filling box is installed on the pulling point fixed in advance; the vertical direction: the vertical pulling piece is passed through the hole on the filling box, and is fixed on the pulling point of the formwork through the connecting piece, and the top of the vertical pulling piece is bound and limited with the web; the horizontal direction: the first horizontal pulling piece and the second horizontal pulling piece are passed through the corresponding through holes, and are assembled with the surrounding rib beams, the filling box is connected into a whole, is fixed in the horizontal direction, so that the multi-directional control pulling connection is achieved, and the floating is prevented.
