Description
Technical Field
[0001] The present application relates to the field of building construction, and in particular to a concrete hollow floor square box fixing structure. Background Art
[0002] The square box hollow floor has the advantages of light weight, flexible space layout and fast construction speed, which reduces the load and foundation cost of the building, adapts to different needs and facilitates the installation of pipelines and equipment, and plays a positive role in reducing construction period and labor costs. The thin-walled square box hollow floor also has good sound insulation and heat insulation performance, providing a comfortable indoor environment.
[0003] The square box hollow floor usually needs to go through the steps of building the formwork frame (including the side wall formwork and the bottom formwork), installing the steel frame, placing the direction, pouring the concrete and removing the formwork to complete, so that after the concrete solidifies, the square box can be stably fixed between the concrete to meet the design requirements.
[0004] However, in actual application, the inventors found that after the direction is placed in the steel frame, when concrete is injected into the formwork, the square box is in an unconstrained state. When it is affected by the impact and buoyancy of the concrete, it will float up, so that the square box cannot be completely covered by concrete. In related technologies, in order to solve the above problems, the square box is usually fixed to the steel frame by iron wire winding. However, there are a large number of square boxes on a floor. The iron wire winding method greatly reduces the speed of fixing the square box on the steel frame. When the iron wire winding is unstable, the square box still has the risk of floating up, which requires further improvement. Utility Model Content
[0005] In order to enable the square box to be stably placed in a placement position, the present application provides a concrete hollow floor square box fixing structure.
[0006] The present application provides a concrete hollow floor square box fixing structure adopts the following technical solution:
[0007] A square box fixing structure for a concrete hollow floor comprises a main frame, a plurality of square boxes and a plurality of fixing rods, wherein the main frame is provided with a plurality of placement areas, each of which is used to place the square boxes, each of which is provided with a positioning hole, and two of the positioning holes are provided, and the two positioning holes are symmetrically arranged about the geometric center of the side wall of the square box, and the fixing rods are respectively penetrated through the positioning holes of the plurality of square boxes arranged along the length of the main frame, and a fixing rod is penetrated through the two positioning holes, and both ends of the plurality of fixing rods are respectively fixedly connected to the main frame.
[0008] By adopting the above technical solution, the operator places the directions in the placement area of the main frame in order, and then uses the fixing rod to penetrate the positioning holes of the square boxes arranged along the length direction of the main frame, and then fixes the two ends of the fixing rod to the main frame. At this time, when pouring concrete on the main frame, the several square boxes arranged along the main frame are in a state of being restrained by the fixing rod, thereby reducing the floating and drifting of the square boxes along the placement area during the process of pouring concrete on the main frame. After the concrete solidifies, the square box can be stably fixed in the concrete, so that the square box can be stably placed in the placement position.
[0009] Preferably, a plurality of the square boxes arranged along the length direction of the main frame can be passed through by one fixing rod;
[0010] Or, a plurality of the square boxes arranged along the length direction of the main frame are connected by a plurality of fixed
[0011] The rods are installed separately.
[0012] By adopting the above technical solution, a fixing rod can be used to fix several square boxes arranged along the length direction of the main frame at the same time, which is easy to operate and highly efficient.
[0013] At the same time, several square boxes arranged along the length direction of the main frame can be fixed using fixing rods with the same number as the number of square boxes. At the same time, one fixing rod can be used to fix a certain number of square boxes. Compared with the method of fixing all square boxes arranged along the length direction of the main frame with one fixing rod, the resistance of the fixing rod when passing through several square boxes can be reduced, so that the fixing rod can be quickly passed through the direction with high efficiency.
[0014] Preferably, the fixing rod is configured as a screw rod, and the screw rod is threadably matched with the positioning hole.

[0017] By adopting the above technical solution, the cross-section of the square steel is a rectangular parallelepiped. Compared with the fixing rod with a circular cross-section, the cooperation between the square steel and the positioning hole helps to reduce the swing of the square box along the axis of the fixing rod.
[0018] Preferably, a positioning member is provided on the main frame, and when any one end of the fixing rod is located in the main frame, the positioning member abuts against the fixing rod, and the positioning member is used to limit the movement of the fixing rod.
[0019] By adopting the above technical solution, the two ends of the fixing rod are fixed by the positioning piece, so that the fixing rod is in a constrained state, which to a certain extent solves the problem that the fixing rod swings along the main frame, causing several square boxes installed on the fixing rod to swing synchronously.

[0021] By adopting the above technical solution, when the positioning frame is installed on the main frame, the fixing rod is stably installed on the main frame through the cooperation between the plug hole and the fixing rod, thereby reducing the swing of the fixing rod along the main frame.
[0022] Preferably, a secondary limiting member is provided on the main frame, and the secondary limiting member includes a plurality of limiting steel bars, and the plurality of limiting steel bars are laid on the main frame along the arrangement direction of the plurality of square boxes, and the plurality of limiting steel bars can abut against the surfaces of the plurality of square boxes.
[0023] By adopting the above technical solution, after the fixing rods are passed through several directions along the length direction of the main frame, several square boxes are fixed by several limiting steel bars, which helps to reduce the swing of the square boxes along the axis direction of the fixing rods.

[0025] By adopting the above technical solution, the main frame and the bottom formwork are suspended through a number of stirrups. When pouring concrete on the main frame, the gap between the lower surface of the square box and the bottom formwork bracket is filled due to the fluidity of the concrete, so that the square box can be completely covered by the concrete to meet the design requirements.
[0026] In summary, the present application includes at least one of the following beneficial technical effects:
[0027] 1. Several square boxes are fixed by fixing rods, and both ends of the fixing rods are also in a fixed state, thereby reducing the floating and drifting in the placement area along the direction during the pouring of concrete on the main frame;
[0028] 2. The screw rod and the positioning hole cooperate so that when the screw rod is turned, the screw rod can be quickly inserted into the square box.

[0036] The following is combined with Figure 1-5 This application is described in further detail.
[0037] The present application embodiment discloses a concrete hollow floor square box fixing structure. Figure 1 A concrete hollow floor square box fixing structure includes a main frame 1, a plurality of square boxes 2 and a plurality of fixing rods 3. The main frame 1 is provided with a plurality of placement areas 4, wherein the main frame 1 includes a plurality of transverse steel bars 11 and a plurality of longitudinal steel bars 12. The plurality of transverse steel bars 11 are arranged horizontally and transversely, and the plurality of longitudinal steel bars 12 are arranged horizontally and longitudinally and penetrated in the plurality of transverse steel bars 11, and the plurality of longitudinal steel bars 12 are arranged at the same intervals, thereby forming a plurality of placement areas 4, and the placement areas 4 are all used for placing the square boxes 2.
[0038] It also includes a plurality of positioning stirrups 7, which are laid on the bottom form, and the main frame 1 is erected on the plurality of positioning stirrups 7. Through the plurality of stirrups, the main frame 1 and the bottom form are suspended in the air. When pouring concrete on the main frame 1, the concrete has fluidity, thereby filling the gap between the lower surface of the square box 2 and the bottom form support, so that the square box 2 can be completely covered with concrete to meet the design requirements.
[0039] It should be noted that the plurality of transverse steel bars 11 and the plurality of longitudinal steel bars 12 are formed by bundling steel bars, which is a conventional technology in building construction. Meanwhile, the “several” and “several” are quantitative terms. Since there are a large number of transverse steel bar bodies, longitudinal steel bar bodies and placement areas 4, their quantities are not described here.
[0040] Correspondingly, several square boxes 2 are penetrated with positioning holes 21 along the horizontal direction, and there are two positioning holes 21. The two positioning holes 21 are symmetrically arranged about the geometric center of the side wall of the square box 2. The fixing rods 3 are penetrated one by one in the positioning holes 21 of several square boxes 2 arranged along the length direction of the transverse steel frame 11 or the longitudinal steel frame 12, and the two positioning holes 21 are penetrated by fixing rods 3. After the fixing rods 3 pass through several square boxes 2 one by one, the two ends of the fixing rods 3 can be fixedly connected to the transverse steel frame 11 or the longitudinal steel frame 12, so that the fixing rods 3 carry several square boxes 2 and are stably placed in the placement area 4, thereby reducing the drift or floating of the square boxes 2 along the placement area 4 during the pouring of concrete on the main frame 1.
[0041] One implementation method is: Please refer to Figure 1 and Figure 2 The fixing rod 3 is set as a screw 31, and the screw 31 is threadedly matched with the positioning hole 21. During the production process of the square box 2, the positioning hole 21 has been integrally formed with a thread. At this time, the screw 31 can be threadedly matched with the positioning hole 21 to achieve a stable connection between the screw 31 and several square boxes 2.
[0042] It should be noted here that the threaded fit between the screw rod 31 and the positioning hole 21 is different from the conventional threaded fit requirements, that is, the fit between the screw rod 31 and the positioning hole 21 allows looseness or errors to occur, so as to reduce the resistance when the square box 2 is installed on the screw rod 31, making it easier for the operator to connect the screw rod 31 with several square boxes 2 in an orderly manner.
[0043] In another embodiment, please refer to Figure 1 and Figure 3The fixing rod 3 is set to a square steel 32, the cross-sectional stroke of the square steel 32 is set to a rectangular parallelepiped shape, and the square steel 32 can be inserted into the positioning hole 21. At the same time, in order to ensure that the cast floor has good stability, the square steel 32 needs to be made of solid material, and its size can be changed according to the size of the positioning hole 21 on the square box 2. Compared with the fixing rod 3 with a circular cross-sectional shape, the cooperation between the square steel 32 and the positioning hole 21 helps to reduce the swing of the square box 2 along the axis direction of the fixing rod 3, thereby helping to reduce the shaking of the square box 2 along the placement area 4 during the concrete pouring process.
[0044] Reference Figure 1-Figure 3 In any figure, a plurality of square boxes 2 arranged along the length direction of the main frame 1 can be penetrated by a fixing rod 3; or a plurality of square boxes 2 arranged along the length direction of the main frame 1 can be penetrated by a plurality of fixing rods 3 respectively.
[0045] Specifically, after arranging several square boxes 2 in order along the transverse steel frame 11 or the longitudinal steel frame 12, the operator uses the fixing rod 3 to sequentially penetrate the positioning holes 21 of several square boxes 2 arranged in the same direction, and then fixes the two ends of the fixing rod 3 on the transverse steel frame 11 or the longitudinal steel frame 12. For the case where the number of square boxes 2 arranged in the same direction is small, using one fixing rod 3 to fix several square boxes 2 arranged in the same direction is a preferred implementation method.
[0046] Correspondingly, when the number of square boxes 2 arranged along the transverse reinforcement frame 11 or the longitudinal reinforcement frame 12 is large, if a fixing rod 3 is directly used to fix several square boxes 2, as the number of square boxes 2 increases, the resistance encountered by the fixing rod 3 when passing through the positioning hole 21 gradually increases, making it inconvenient for the operator to insert the fixing rod 3 into several square boxes 2. Therefore, several square boxes 2 arranged along the transverse reinforcement frame 11 or the longitudinal reinforcement frame 12 can be successively penetrated by several fixing rods 3, for example, one fixing rod 3 only fixes ten square boxes 2. After placing ten square boxes 2 in the placement area 4 in the same direction, a fixing rod 3 is used to fix the current ten square boxes 2. After fixing both ends of the current fixing rod 3 to the transverse steel frame 11 or the longitudinal steel frame 12, ten square boxes 2 are laid along the same direction, and then fixed with the fixing rod 3. The above process greatly reduces the resistance encountered by the fixing rod 3 during the process of passing through the square box 2, which facilitates the operator to insert the fixing rod 3 into the square box 2. This method is suitable for the situation where a large number of square boxes 2 are arranged in the same direction.
[0047] Reference Figure 4 and Figure 5 A positioning member 5 is provided on the main frame 1. When any end of the fixing rod 3 is located in the main frame 1, the positioning member 5 abuts against the fixing rod 3. The positioning member 5 is used to limit the movement of the fixing rod 3.
[0048] For details, please refer to Figure 5 , one embodiment is: the positioning member 5 is set as a positioning frame 51, the positioning frame 51 is detachably connected to the main frame 1, the positioning frame 51 is provided with a plug hole adapted to the cross-sectional profile of the fixing rod 3, the positioning rod is plugged into the plug hole, the positioning frame 51 includes an inner ring 512, an outer ring 511 and a connecting rod 513, the inner ring 512, the outer ring 511 and the connecting rod 513 are all made of steel bars, the outline surrounded by the inner ring 512 is adapted to the cross-sectional profile of the fixing rod 3, and the inner ring 512 and the outer ring 511 are formed by welding using the connecting rod 513, so that the outer ring 511 and the inner ring 512 are stably connected, and then the outer ring 511 is fixed to the transverse steel bar frame 11 or the longitudinal steel bar frame 12 by iron wire, so that the fixing rod 3 is stably connected to the transverse steel bar frame 11 or the longitudinal steel bar frame 12, thereby reducing the offset of the installation position of the fixing rod 3 during concrete pouring.
[0049] Please refer to Figure 4 In another embodiment, a secondary limiting member 6 is provided on the main frame 1, and the secondary limiting member 6 includes a plurality of limiting steel bars 61, and the plurality of limiting steel bars 61 are laid on the main frame 1 along the arrangement direction of the plurality of square boxes 2, and the plurality of limiting steel bars 61 can abut against the surfaces of the plurality of square boxes 2.
[0050] Specifically, in the present embodiment, two limiting steel bars 61 are provided, and the two limiting steel bars 61 are fixed to the transverse steel bar frame 11 or the longitudinal steel bar frame 12 by iron wire along the length direction of the transverse steel bar frame 11 or the longitudinal steel bar frame 12. The purpose is that when the fixing rod 3 is inserted into the positioning hole 21 of the square box 2, there is a matching gap between the fixing rod 3 and the positioning hole 21, so that the square box 2 can swing along the axis of the fixing rod 3. Therefore, the upper surface of the square box 2 is fixed by the two limiting steel bars 61, thereby limiting the swing of the square box 2 along the axis of the fixing rod 3, so that when the main frame 1 is poured with concrete, the square box 2 can be completely covered with concrete.
[0051] The implementation principle of a square box fixing structure of a concrete hollow floor in an embodiment of the present application is as follows: an operator places the square boxes 2 in the placement area 4 of the main frame 1 in an orderly manner, and then uses a fixing rod 3 to penetrate into the positioning hole 21 of the square box 2 arranged along the length direction of the main frame 1, and then fixes both ends of the fixing rod 3 to the main frame 1. At this time, when pouring concrete on the main frame 1, several square boxes 2 arranged along the main frame 1 are in a state of being constrained by the fixing rod 3, thereby reducing the floating and drifting of the square box 2 along the placement area 4 during the process of pouring concrete on the main frame 1. After the concrete solidifies, the square box 2 can be stably fixed in the concrete, so that the square box 2 can be stably placed in the placement position.
[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
