Description

Technical Field

[0001] The present invention relates to the technical field of building construction applications, and particularly to a connecting member for a lightweight hollow floor slab and a connecting method thereof. Background Art

[0002] A hollow floor slab is a new type of floor slab structure with a hollow structure inside (such as holes formed by internal molds such as hollow pipes and thin-walled square boxes), and has the characteristics of light self-weight, excellent space performance, good sound insulation and heat insulation, and good economy. It is widely used in the fields of residential, public, and industrial buildings.

[0003] When installing the existing floor slabs, the placement positions need to be manually positioned and fixed. The complex construction and excessive weight result in different distances between each adjacent floor slab, making it impossible to install the steel bar frames flexibly in the later stage. Moreover, when using the steel bar frames for connection and fixation, the adjacent floor slabs cannot be tightened and reinforced, thus reducing the connection firmness between adjacent floor slabs during the later pouring, resulting in insufficient performance in use, and the stress concentration at the joints affects the seismic performance. Therefore, the present invention provides a connecting member for a lightweight hollow floor slab and a connecting method thereof. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a connecting member for a lightweight hollow floor slab and a connecting method thereof. By providing a predetermined member between adjacent floor slabs, when installing multiple floor slabs, they can be quickly arranged equidistantly, facilitating the later pouring and fixation at the connection. Moreover, a connecting component and a locking component are provided between adjacent floor slabs, enabling the adjacent floor slabs to be quickly tightened and fixed, and cooperating with the predetermined member to achieve a firm connection between adjacent floor slabs.

[0005] To solve the above technical problem, one technical solution adopted by the present invention is: to provide a connecting member for a lightweight hollow floor slab, including a floor slab body; A plurality of predetermined members circumferentially distributed with the center of the floor slab body as the center of the circle, used for pre-positioning and fixing the adjacent connected floor slab bodies; A connecting component detachably installed at the middle position around the floor slab body, used for connecting and fixing the adjacent placed floor slab bodies; and A locking component threadedly connected to the middle position of the relatively arranged connecting components, used for connecting the connecting components arranged on the opposite faces of the adjacent floor slab bodies.

[0006] The present invention is further provided as: extension parts are provided at the corners of the floor slab body, and slots are opened at the bottoms of the floor slab body and the extension parts.

[0007] Through the above technical solution, the strength of the entire floor slab body can be increased by using the provided extension part, and the extension part can play a certain connection strength in the later overall pouring. The slotted opening at the bottom can reduce the weight of the entire floor slab body, facilitating lightweight setting.

[0008] The present invention is further configured as follows: The predetermined component includes a positioning and strengthening rib connecting adjacent floor slab bodies. Both end faces of the positioning and strengthening rib are fixedly connected with positioning blocks. The positioning blocks are embedded inside the central holes opened at the center of the top of the floor slab body. The positioning and strengthening rib is installed inside the hidden groove correspondingly opened at the top of the floor slab body.

[0009] Through the above technical solution, the distance between adjacent floor slab bodies can be fixed by using the positioning and strengthening rib. And under the action of the positioning blocks, the adjacent floor slab bodies can be tightened and fixed, increasing the stability between adjacent floor slab bodies.

[0010] The present invention is further configured as follows: The positioning block is provided in a quarter-ring shape, and the four positioning blocks are mutually pressed and fitted with the inner wall of the central hole.

[0011] Through the above technical solution, it is convenient to stably install the predetermined component on the top of the floor slab body by using the positioning blocks, and enables multiple adjacent floor slab bodies to be arranged at equal distances, facilitating later operations.

[0012] The present invention is further configured as follows: The connecting component includes a connecting plate. A connecting cylinder is penetrated through the center of the connecting plate. Connecting screws are penetrated through the positions near the corners of the connecting plate. Oppositely engaged connecting clamping plates are penetrated through the middle positions of two groups of vertically distributed connecting screws. The two groups of connecting clamping plates are respectively installed on the connecting ribs provided on the side of the floor slab body.

[0013] Through the above technical solution, the positions of multiple connecting screws can be fixed by using the connecting clamping plates. And the connecting screws extend into the interior of the floor slab body to further improve the strength during connection. At the same time, the connecting cylinder in the middle of the connecting plate can be used to achieve mutual tension, thereby increasing the firmness between adjacent floor slab bodies.

[0014] The present invention is further configured as follows: Limiting nuts are threadedly connected to the end faces of the two groups of connecting screws, and the side walls of multiple limiting nuts are abutted against the side wall of the connecting plate. At the same time, the end faces of the two groups of connecting screws away from the connecting plate are respectively threadedly inserted into the connecting holes opened at the positions near the corners on the side of the floor slab body.

[0015] Through the above technical solution, when installing the connecting screw rod, it can be threadedly inserted into the interior of the floor slab body, thereby improving the connection strength. And using the limit nut can stably install the connecting plate on the end face of the connecting screw rod to achieve the overall connection and fixation.

[0016] The present invention is further configured that: the two connecting clamping plates respectively cover the outer walls of the two connecting ribs through the clamping grooves opened on their opposite faces, and the opposite faces of the two connecting clamping plates are both provided with engaging teeth. Tightening nuts threadedly connected to the outer wall of the connecting screw rod are tightly abutted on both sides of the two connecting plates.

[0017] Through the above technical solution, it is convenient for the connecting clamping plates to be fitted and installed on the connecting ribs, and using the tightening nuts can reinforce the installed connecting clamping plates, so that the connecting clamping plates are stably installed on the connecting ribs.

[0018] The present invention is further configured that: the locking assembly includes a hollow sleeve, symmetrically arranged tensioning screw rods are provided inside the hollow sleeve, end plates are fixedly connected to the opposite end faces of the two tensioning screw rods, damping springs are wrapped around the outer walls of the two tensioning screw rods, rotation blocks are fixedly connected to the outer walls of the two tensioning screw rods near the middle positions, and the end faces of the two tensioning screw rods are threadedly connected to the interiors of two corresponding connecting cylinders.

[0019] Through the above technical solution, the two tensioning screw rods are respectively connected to the connecting cylinders on both sides. By driving the rotation of the rotation blocks with an external tool, the tensioning screw rods are continuously extended into the interiors of the connecting cylinders, so as to use the connecting blocks on the connecting cylinders to drive the connecting assemblies on both sides to tighten and fix the floor slab body connected thereto. At the same time, cooperate with the predetermined components to achieve a firm connection between adjacent floor slab bodies.

[0020] The present invention is further configured that: the two tensioning screw rods both penetrate through the two end faces of the hollow sleeve and are slidably connected thereto. At the same time, the damping springs are located inside the hollow sleeve, and the two end faces respectively abut against the end plates and the inner walls of the hollow sleeve.

[0021] Through the above technical solution, the tensioning screw rods arranged in a penetrating manner can enable the connecting assemblies on both sides to move relatively, thereby achieving a firm connection between adjacent floor slab bodies. And using the internal damping springs can achieve the resilient connection of the tensioning screw rods to prevent tensioning damage caused by rigid connection.

[0022] On the other hand, a connection method for a connection member of a lightweight hollow floor slab is provided, including the following steps: S1. First, neatly place the floor slab body to be installed in the corresponding position, and install the predetermined components through the positioning blocks inside them respectively into the central holes opened at the tops of multiple adjacent floor slab bodies placed side by side.

Then, use two groups of connecting screws to penetrate the two groups of connecting clamping plates near the end faces respectively, and thread the end faces of the two groups of connecting screws into the correspondingly opened connecting holes. At the same time, use fastening nuts to reinforce the connecting clamping plates; S4. Then, install the connecting plate at the end face positions of the two groups of connecting screws and fix it with limit nuts; S5. Finally, the two tensioning screws of the locking assembly are respectively connected to the connecting cylinders on both sides. By driving the rotation of the rotating block with an external tool, the tensioning screws are continuously extended into the connecting cylinders, so that the connecting blocks on the connecting cylinders drive the connecting assemblies on both sides to drive the floor slab bodies connected to them to be tensioned and fixed. At the same time, cooperate with the predetermined components to achieve firm connection between adjacent floor slab bodies.

[0026] The following elaborates on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0027] As Figures 1-4 shown, a connecting member of a lightweight hollow floor slab includes a floor slab body 1. Extension parts 13 are provided at the corners of the floor slab body 1. Grooves 16 are opened at the bottoms of the floor slab body 1 and the extension parts 13. The provided extension parts 13 can increase the strength of the entire floor slab body 1, and the extension parts 13 can play a certain connection strength during the later overall pouring. The grooves 16 opened at the bottom can reduce the weight of the entire floor slab body 1, facilitating lightweight setting.

[0028] As Figure 2 and Figure 5As shown, a plurality of predetermined components 2 are circumferentially distributed with the center of the floor slab body 1 as the center of the circle, and are used for pre-positioning and fixing the adjacent connected floor slab bodies 1. The predetermined component 2 includes a positioning and strengthening rib 21 connecting adjacent floor slab bodies 1. Both end faces of the positioning and strengthening rib 21 are fixedly connected with positioning blocks 22. The positioning blocks 22 are embedded inside a central hole 11 opened at the top center of the floor slab body 1. The positioning blocks 22 are arranged as quarter circles, and the four positioning blocks 22 are mutually extruded and fitted with the inner wall of the central hole 11, which is convenient for stably installing the predetermined component 2 on the top of the floor slab body 1 by using the positioning blocks 22, and enables a plurality of adjacent floor slab bodies 1 to be arranged at equal intervals, facilitating subsequent operations. The positioning and strengthening rib 21 is installed inside a hidden groove 12 correspondingly opened at the top of the floor slab body 1. The positioning and strengthening rib 21 can be used to fix the distance between adjacent floor slab bodies 1, and under the action of the positioning blocks 22, the adjacent floor slab bodies 1 can be tightened and fixed, increasing the stability between adjacent floor slab bodies 1.

[0029] As Figure 6 and Figure 7As shown, the connecting component 3 is detachably installed at the middle positions around the four sides of the floor slab body 1 and is used to connect and fix adjacent floor slab bodies 1. The connecting component 3 includes a connecting plate 31. A connecting cylinder 32 is penetrated through the center of the connecting plate 31. Connecting screws 33 are penetrated through the positions near the corners of the connecting plate 31. Limit nuts 331 are threadedly connected to the end faces of the two groups of connecting screws 33, and the side walls of the multiple limit nuts 331 are abutted against the side wall of the connecting plate 31. At the same time, the end faces of the two groups of connecting screws 33 away from the connecting plate 31 are respectively threadedly inserted into the connecting holes 14 opened at the positions near the corners on the side of the floor slab body 1, which is convenient for the connecting screws 33 to be threadedly inserted into the interior of the floor slab body 1 during installation, so as to improve the connection strength. And the use of the limit nuts 331 can stably install the connecting plate 31 on the end face of the connecting screw 33 to achieve the overall connection and fixation. Relatively engaging connecting splints 34 are penetrated through the positions near the middle of the two groups of vertically distributed connecting screws 33. The two groups of connecting splints 34 respectively cover the outer walls of the two connecting ribs 15 through the clamping grooves 341 opened on their opposite faces, and the opposite faces of the two groups of connecting splints 34 are provided with engaging teeth. Tightening nuts 332 threadedly connected to the outer walls of the connecting screws 33 are abutted against both sides of the two groups of connecting splints 34, which is convenient for the connecting splints 34 to be fitted and installed on the connecting ribs 15, and the use of the tightening nuts 332 can reinforce the installed connecting splints 34, so that the connecting splints 34 are stably installed on the connecting ribs 15. The two groups of connecting splints 34 are respectively installed on the connecting ribs 15 arranged on the side of the floor slab body 1. The connecting splints 34 can be used to fix the positions of the multiple connecting screws 33, and the connecting screws 33 extending into the interior of the floor slab body 1 further improve the strength during connection. At the same time, the connecting cylinder 32 in the middle of the connecting plate 31 can be used to achieve mutual tension, thereby increasing the firmness between adjacent floor slab bodies 1.

[0030] As Figure 8 and Figure 9As shown in the figure, a locking assembly 4 is threadedly connected to the middle position of the oppositely arranged connecting assemblies, and is used to connect the connecting assemblies 3 arranged on the opposite faces of adjacent floor slab bodies 1. The locking assembly 4 includes a hollow sleeve 41. Inside the hollow sleeve 41, tension screws 42 are symmetrically arranged. Both tension screws 42 penetrate through the two end faces of the hollow sleeve 41 and are slidably connected thereto. At the same time, damping springs 44 are located inside the hollow sleeve 41, and the two end faces respectively abut against the end plate 43 and the inner wall of the hollow sleeve 41. By using the tension screws 42 arranged through, the connecting assemblies 3 on both sides can be relatively moved, so as to realize the firm connection of adjacent floor slab bodies 1. And by using the internal damping springs 44, the flexible connection of the tension screws 42 can be realized, preventing the tension damage caused by rigid connection. Fixedly connected to the opposite end faces of both tension screws 42 are end plates 43. Damping springs 44 are wrapped around the outer walls of both tension screws 42. Fixedly connected to the outer walls of both tension screws 42 near the middle position are rotating blocks 45. And the end faces of both tension screws 42 are threadedly connected to the inside of two corresponding connecting cylinders 32. The two tension screws 42 are respectively connected to the connecting cylinders 32 on both sides. By driving the rotation of the rotating block 45 with an external tool, the tension screws 42 are continuously extended into the connecting cylinders 32. Thus, the connecting assemblies 3 on both sides drive the floor slab bodies 1 connected thereto to be tensioned and fixed by using the connecting blocks 31 on the connecting cylinders 32. At the same time, in cooperation with the predetermined member 2, the firm connection between adjacent floor slab bodies 1 is realized.

[0031] As Figures 1-9 shown, a connection method for a connection member of a lightweight hollow floor slab includes the following steps: S1. First, neatly place the floor slab body 1 to be installed in the corresponding position, and install the predetermined member 2 into the central holes 11 opened at the tops of a plurality of adjacent floor slab bodies 1 respectively through the positioning blocks 22 inside it. At the same time, place the positioning reinforcing ribs 21 in the hidden grooves 12 to realize the equidistant placement of a plurality of adjacent floor slab bodies 1; S2. Then, cover the outer walls of the two connecting ribs 15 with two groups of connecting clamping plates 34 respectively through the clamping grooves 341 arranged inside them; S3. Then, use two groups of connecting screws 33 to respectively penetrate through the positions near the end faces of the two groups of connecting clamping plates 34, and thread the end faces of the two groups of connecting screws 33 into the correspondingly opened connecting holes 14. At the same time, use fastening nuts 332 to reinforce the connecting clamping plates 34; S4. Then, install the connecting plate 31 at the end face positions of the two groups of connecting screws 33 and fix it with a limit nut 331; S5. The two tension screws 42 of the final locking assembly 4 are respectively connected to the connecting cylinders 32 on both sides. By driving the rotation of the rotating block 45 with an external tool, the tension screws 42 are continuously extended into the connecting cylinders 32, so that the connecting blocks 31 on the connecting cylinders 32 are used to drive the connecting assemblies 3 on both sides to tightly fix the floor slab body 1 connected thereto. At the same time, the adjacent floor slab bodies 1 are firmly connected by cooperating with the predetermined member 2.
