Description

Technical Field

[0001] The present application relates to the technical field of building floors, and in particular to a supporting structure and a leveling process for an assembled overhead floor. Background Art

[0002] Prefabricated elevated floor is a modern building floor, mainly used in working conditions where drainage, heating, electrical and other pipeline equipment need to be laid on the foundation floor. It can separate the floor used to support objects and for people to walk on from the pipeline equipment below.

[0003] Existing prefabricated elevated floors are usually manufactured in factories and then assembled and installed on site. They are mainly composed of adjustable supporting structures and floor layers. By adjusting the supporting structure, the heights of multiple floor layers can be made consistent to form a flat floor, and sufficient space for laying pipelines and equipment can be formed under the floor layers. They combine the technical advantages of factory production and on-site assembly, bringing innovation and change to the construction industry.

[0004] However, in the existing prefabricated elevated floors, the adjustable supporting structure is usually leveled and fixed by the combination of bolts and nut threads. During the use of the prefabricated elevated floors after leveling, when the floor layer is stepped on and vibrates frequently, the bolts and nuts are prone to produce thread backlash due to resonance, which not only affects the stability of the prefabricated elevated floors, but also poses a greater risk of collapse of the prefabricated elevated floors due to uneven stress on the bolt thread backlash. Summary of the invention

[0005] The present application provides a support structure and leveling process for an assembled elevated floor, which can effectively prevent bolt backthreading, thereby effectively improving the stability and safety of the assembled elevated floor.

[0006] On the one hand, the present application provides a support structure for an assembled overhead floor, which adopts the following technical solution: A supporting structure of an assembled overhead floor, arranged at the corners of the floor layer, comprising bolts, nuts and supporting members; The nut is arranged on the floor layer, and the axis of the nut is parallel to the thickness direction of the floor layer; The tail of the bolt is matched with the thread of the nut, and a clearance opening is provided on the floor slab for the tail of the bolt to pass through, and the clearance opening passes through both sides of the floor slab along the thickness direction of the floor slab; the support member is arranged at the head of the bolt, and is used to contact and abut against the foundation floor slab; A plurality of grooves are formed on a side of the nut close to the floor layer, and the grooves are communicated with the clearance opening; a cavity is formed inside the support member, a plurality of first openings are formed through the bottom of the support member, a plurality of second openings are formed through the peripheral side of the support member, and the first openings and the second openings are both communicated with the cavity; a through hole is formed inside the bolt, and the through hole passes through both ends of the bolt along the axial direction of the bolt, and both ends of the through hole are communicated with the clearance opening and the cavity respectively; The through hole is filled with adhesive, and the adhesive can flow out through the first through port and the second through port and can fill the clearance port.

At the same time, it can effectively absorb the destructive force generated by resonance during the use of the prefabricated elevated floor, effectively prevent the backlash between the nut and the bolt due to resonance, and effectively eliminate abnormal noise, thereby effectively improving the stability and safety of the prefabricated elevated floor.

[0010] Optionally, the filling nozzle is movably connected to the connecting piece, and the moving direction of the filling nozzle is parallel to the thickness direction of the floor layer; When the filling nozzle moves toward the direction approaching the bolt until it abuts against the bolt, the filling hole is communicated with the through hole.

[0012] Optionally, an elastic member is also included; The elastic member is arranged inside the connecting member, and the two ends of the elastic member are respectively connected to the filling nozzle and the connecting member. The elastic member has a tendency to drive the filling nozzle to move in a direction away from the bolt to an extreme position and maintain it, and at this time, the end of the filling nozzle away from the bolt is flush with the end face of the connecting member.

[0013] By adopting the above technical scheme, the filling nozzle can be kept flush with the end face of the connecting piece before and after filling, so as to further effectively ensure the aesthetics of the assembled elevated floor after construction; at the same time, it can protect the through hole before filling, reducing the probability of external impurities entering the through hole to form a blockage and affecting the subsequent filling.

[0014] Optionally, a blocking block is also included; The blocking block is disposed in the through hole to form a blockage in the through hole, and in an initial state, the blocking block is located at an end of the through hole away from the head of the bolt.

[0015] By adopting the above technical solution, the blocking block before filling can further reduce the probability of foreign matter entering the through hole, thereby further ensuring the effect of subsequent filling with adhesive.

[0016] Optionally, the blocking block can move along the through hole; when the blocking block moves to an extreme position in a direction close to the supporting member, the through hole is communicated with the cavity.

[0017] By adopting the above technical solution, the block can move along the through hole under the action of adhesive and gas during filling. In this process, the effect of the adhesive filling the through hole can be effectively improved. At the same time, the filling can be completed without removing the block, thereby further improving the efficiency of filling the adhesive.

[0018] Optionally, the support member is provided with an inserting groove adapted to the blocking block on the cavity wall at the bottom of the cavity, and when the blocking block moves to an extreme position in a direction close to the support member, the blocking block is plugged and matched with the inserting groove and the blocking block is partially located in one end of the through hole close to the bolt head; A plurality of diverter grooves are provided at one end of the block away from the support member, and the diverter grooves are distributed in a circular array on the block with the axis of the through hole as the axis, and at this time, the two ends of the diverter grooves are respectively connected to the through hole and the cavity; the plurality of diverter grooves correspond one-to-one to the plurality of first openings and the plurality of second openings, and the corresponding diverter grooves, the first openings and the second openings are all located in the same radial direction relative to the bolt.

[0019] By adopting the above technical solution, after the through hole is filled with the adhesive, the block can play a supporting effect between the bolt and the support member, thereby improving the structural strength here; and at this time, the block can guide the adhesive to enter the cavity evenly from different directions, and at the same time can guide the adhesive to flow out through the first through port to contact and bond with the foundation floor below the support member and to flow out through the second through port to contact and bond with the foundation floor around the support member, so that the adhesive is more evenly distributed relative to the support member, thereby further improving the stability and reliability of the connection between the support member and the foundation floor through the adhesive, and reducing the probability of the support member being unstable due to different bonding effects between the support member and the foundation floor at different positions.

[0020] Optionally, the second opening is obliquely opened on the support member, and an end of the second opening close to the cavity is an inclined upper end; During the process that the blocking block moves along the through hole, it remains in the through hole to form a blockage.

[0021] By adopting the above technical solution, when the block moves along the through hole during filling, the block can drive the gas in the through hole to enter the cavity and be discharged through multiple second ports. At this time, the gas discharged from the second ports can blow away the impurities on the foundation floor around the support member, thereby effectively improving the bonding effect between the adhesive subsequently flowing out through the second ports and the foundation floor.

[0022] Optionally, it further comprises a plurality of elastic positioning members; the positioning members are arranged at one end of the through hole away from the head of the bolt, and in an initial state, the blocking block is in contact with a plurality of the positioning members at the same time for positioning.

[0023] By adopting the above technical solution, the blocking block can be conveniently kept at the end of the through hole away from the head of the bolt in the initial state, so that the blocking block can maintain a stable position before filling and effectively protect the through hole.

[0024] On the other hand, the present application provides a leveling process, which adopts the following technical solution: A leveling process, based on the above-mentioned supporting structure of an assembled overhead floor, comprises the following steps: S1.

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-8 This application is described in further detail.

[0029] Embodiment 1: The embodiment of the present application discloses a supporting structure of an assembled elevated floor, which plays a supporting role in the structure of the assembled elevated floor.

[0030] Reference Figure 1 The assembled elevated floor comprises a floor layer 1 and a plurality of supporting structures, and the plurality of supporting structures are all arranged on the same side of the floor layer 1 to support the floor layer 1. In this embodiment, the floor layer 1 is preferably a square plate-shaped structure, and the assembled elevated floor comprises four supporting structures in total, and the four supporting structures are all located on one side of the thickness direction of the floor layer 1 and are respectively located at the four corners of the floor layer 1; since the floor layer 1 is a prior art in the art, only the supporting structure will be described in detail later, and the floor layer 1 will not be described in detail, and the floor layer 1 will only be briefly indicated in the attached drawings.

[0031] Reference Figure 1 and Figure 2 The supporting structure includes nuts 2, bolts 3 and supporting members 4. The nuts 2 are used to adjust the supporting structure, thereby adjusting the horizontality of the floor layer 1 and the height relative to the foundation floor; the bolts 3 are used to raise the floor layer 1 and play a major supporting role; the supporting members 4 are used to allow the supporting structure to contact and abut against the foundation floor, so that the supporting structure can support the floor layer 1 based on the foundation floor.

[0032] The floor layer 1 is provided with clearance openings 11 at its four corners along its thickness direction. The clearance openings 11 are cylindrical in shape, and the axis of the clearance openings 11 is parallel to the thickness direction of the floor layer 1. The four clearance openings 11 are distributed in a circular array with the vertical center line of the floor layer 1 as the axis.

[0033] The four nuts 2 correspond to the four clearance openings 11 one by one. The nuts 2 are fixedly connected to the floor slab 1 . The axes of the nuts 2 are parallel to the thickness direction of the floor slab 1 and coincide with the axes of the clearance openings 11 .

[0034] The bolt 3 is threadedly connected to the nut 2, and the bolt 3 is threadedly connected to the nut 2 in a way that the head of the bolt 3 is located on the side of the corresponding nut 2 away from the floor layer 1. At this time, the axis of the bolt 3 coincides with the axis of the clearance opening 11; the bolt 3 can be controlled to rotate relative to the nut 2, so that the bolt 3 can be driven to move along its own axial direction relative to the floor layer 1. During the movement of the bolt 3, the tail of the bolt 3 can enter the corresponding clearance opening 11 and move in the corresponding clearance opening 11; the radial dimension of the clearance opening 11 is larger than the radial dimension of the tail of the bolt 3, which can facilitate the tail of the bolt 3 to enter the clearance opening 11 and move in the clearance opening 11.

[0035] The support member 4 is a circular pancake-shaped structure as a whole, and is fixedly mounted on the head of the corresponding bolt 3, and the axis of the support member 4 coincides with the axis of the bolt 3. The radial dimension of the support member 4 is larger than the radial dimension of the head of the bolt 3, which can effectively expand the contact area between the support structure and the foundation floor.

[0036] The bolt 3 has a through hole 31 formed inside along its own axial direction, and the through hole 31 passes through both ends of the bolt 3 in the axial direction; the support member 4 has a cavity 41 inside, and a plurality of first through holes 42 are formed at the bottom thereof and a plurality of second through holes 43 are formed at the circumferential side thereof, and the plurality of first through holes 42 and the plurality of second through holes 43 are distributed in a circumferential array on the support member 4 with the axis of the support member 4 as the axis, and the first through holes 42 and the second through holes 43 both pass through the support member 4 to form an opening and communicate with the cavity 41. In this embodiment, it is preferred that the first through hole 42 passes through the bottom of the support member 4 downward along the axial direction of the support member 4 to form an opening, and it is preferred that the second through hole 43 passes through the circumferential side of the support member 4 in the radial direction of the support member 4 to form an opening.

[0037] When the bolt 3 is threadedly connected with the nut 2, the two ends of the through hole 31 are respectively connected with the corresponding clearance opening 11 and the corresponding cavity 41; when the height of the floor layer 1 is adjusted by rotating the bolt 3, a certain amount of adhesive is filled into the through hole 31 at one end of the bolt 3 located in the clearance opening 11. After the adhesive fills the through hole 31, it will enter the cavity 41 and flow out through multiple first openings 42 and multiple second openings 43. The adhesive flowing out of the first opening 42 will directly contact the basic floor below the support 4, and the adhesive flowing out of the second opening 43 will contact the basic floor around the support 4; after the adhesive solidifies, additional connections will be formed between the support 4 and the basic floor, and between the bolt 3 and the support 4, so as to further improve the connection strength between the support 4 and the basic floor, and between the bolt 3 and the support 4. In this embodiment, the preferred adhesive is polyurethane foam glue. Since polyurethane foam glue is a common prior art, it will not be described in detail here.

[0038] Furthermore, in order to improve the position stability of the bolt 3 after rotation adjustment relative to the nut 2, it is preferred that a plurality of grooves 21 are opened at one end of the nut 2 close to the floor layer 1, the grooves 21 are connected to the corresponding clearance openings 11, and the plurality of grooves 21 are distributed in a circular array on the nut 2 with the axis of the nut 2 as the axis.

[0039] After a certain amount of adhesive is filled into the through hole 31, in order to make the surface of the floor layer 1 after the construction of the prefabricated elevated floor more beautiful, the adhesive will continue to be filled into the makeshift opening 11 so that the adhesive can fill the makeshift opening 11 and the solidified adhesive in the makeshift opening 11 can form an end surface flush with the top end surface of the floor layer 1.

[0040] During the process of filling the makeshift opening 11 with adhesive, the adhesive entering the makeshift opening 11 will come into contact with the nut 2 and at the same time be able to enter the several grooves 21 on the nut 2; after the adhesive solidifies, additional connections will be formed between the nut 2 and the floor layer 1, between the nut 2 and the bolt 3, and between the bolt 3 and the floor layer 1, thereby further improving the connection strength between the nut 2 and the floor layer 1, between the nut 2 and the bolt 3, and between the bolt 3 and the floor layer 1.

[0041] At this time, the nut 2 can not only maintain a relative position fixed relative to the floor layer 1 under the action of the adhesive solidified in the clearance opening 11, but also maintain a relative position fixed relative to the bolt 3 under the action of the adhesive solidified in the clearance opening 11, thereby effectively preventing thread backlash and improving the stability and safety of the assembled elevated floor.

[0042] The implementation principle of the supporting structure of an assembled overhead floor in the embodiment of the present application is: According to the height of the space required between the assembled overhead floor and the foundation floor after construction, multiple support structures on the same floor layer 1 are adjusted, and multiple bolts 3 are rotated in sequence so that the floor layer 1 is placed on the foundation floor through multiple bolts 3 and multiple support members 4, and the surface of the floor layer 1 is kept horizontal and the distance between the floor layer 1 and the foundation floor meets the requirements; First, a certain amount of adhesive is filled into the multiple through holes 31 in sequence. After filling the through holes 31, the adhesive will flow into the corresponding cavity 41 to fill the cavity 41, and then flow out through the multiple first through holes 42 and the multiple second through holes 43 to contact the basic floor slab; then the adhesive is filled into the multiple clearance openings 11 in sequence until the adhesive fills the clearance openings 11. After the adhesive solidifies, the support member 4 will be fixed relative to the basic floor slab, and the nut 2 will also be fixed relative to the floor slab layer 1 and the corresponding bolt 3. At the same time, the top surface of the floor slab layer 1 is flush, thereby achieving the beauty of the assembled elevated floor slab after construction, and at the same time improving the stability and safety of the assembled elevated floor slab.

[0043] Embodiment 2: Reference Figure 3 and Figure 4 , the difference between this embodiment and embodiment 1 lies in the floor slab layer 1 and the support member 4; Reference Figure 4 and Figure 5 In this embodiment, the supporting structure further includes a connecting member 5, a filling nozzle 6, an elastic member 7, a blocking block 8 and a plurality of positioning members 9.

[0044] Among them, the connecting piece 5 is used to facilitate the connection between the nut 2 and the floor layer 1, and at the same time can effectively improve the reliability of the supporting structure for the floor layer 1; the filling nozzle 6 is used to facilitate the staff to fill the adhesive into the through hole 31 or the make way opening 11; the elastic member 7 can further facilitate the staff to use the filling nozzle 6; the blocking block 8 is used to keep the inside of the through hole 31 unobstructed before filling the adhesive, and to protect the through hole 31 in the through hole 31; the positioning piece 9 is used to facilitate the blocking block 8 to maintain a stable position in the through hole 31 before filling the adhesive.

[0045] Reference Figure 3 and Figure 4 The floor 1 is provided with a snap-in groove 12 at the bottom of the four clearance openings 11. The snap-in groove 12 is in the shape of a circular ring structure. The snap-in groove 12 is communicated with the corresponding clearance opening 11, and the axis of the snap-in groove 12 coincides with the axis of the clearance opening 11.

[0046] The connecting member 5 is of cylindrical structure as a whole and is matched with the shape of the clearance opening 11. The interior of the connecting member 5 has a space for the tail of the bolt 3 to enter the clearance opening 11, and one end of the connecting member 5 in the axial direction has a clamping portion 51 matched with the clamping groove 12; the connecting member 5 is fixedly connected to the floor layer 1, and after the connection, the connecting member 5 is entirely located in the clearance opening 11, and its clamping portion 51 is clamped and matched with the corresponding clamping groove 12; at this time, the end faces of the connecting member 5 on both sides in the axial direction are respectively flush with the end faces of the floor layer 1 on both sides in the thickness direction, so as to ensure the beauty of the floor layer 1 after the construction of the assembled overhead floor.

[0047] The nut 2 is fixedly connected to the corresponding connecting piece 5, and at this time, the axis of the nut 2 also coincides with the axis of the corresponding connecting piece 5; after the nut 2 is fixedly connected to the connecting piece 5, the end of the nut 2 close to the corresponding connecting piece 5 not only contacts and abuts against the clamping portion 51, but also contacts and abuts against the portion of the floor layer 1 around the corresponding clamping groove 12.

[0048] Reference Figure 5 and Figure 6 The filling nozzle 6 is a cylindrical structure as a whole and is movably installed on the connecting member 5. After the filling nozzle 6 is installed on the connecting member 5, the axis of the filling nozzle 6 coincides with the axis of the connecting member 5, and the movable direction of the filling nozzle 6 is parallel to its own axis direction.

[0049] The packing nozzle 6 is limited in its movement relative to the connecting member 5. When the packing nozzle 6 moves to the extreme position in the direction close to the corresponding nut 2, the packing nozzle 6 can contact and abut against the tail of the bolt 3 located in the corresponding clearance opening 11; when the packing nozzle 6 moves to the extreme position in the direction away from the corresponding nut 2, the end of the packing nozzle 6 away from the corresponding nut 2 is flush with the end face of the connecting member 5 away from the corresponding nut 2.

[0050] A filling hole 61 for filling adhesive is provided inside the filling nozzle 6 along its own axial direction. The axis of the filling hole 61 coincides with the axis of the filling nozzle 6 and penetrates through both ends of the filling nozzle 6 to form an opening. When the filling nozzle 6 moves to the extreme position in the direction close to the corresponding nut 2, the two ends of the filling hole 61 are respectively connected to the space above the filling nozzle 6 and the through hole 31. When the filling nozzle 6 moves to the extreme position in the direction away from the corresponding nut 2, the two ends of the filling hole 61 are respectively connected to the space above the filling nozzle 6 and the aperture located inside the connector 5 in the clearance opening 11. In this embodiment, in order to facilitate the communication between the filling hole 61 and the through hole 31, it is preferred that the bottom of the filling nozzle 6 has a shrinking structure, and the end of the through hole 31 away from the head of the bolt 3 is in an expanded shape adapted to the shrinking structure of the filling nozzle 6. At this time, when the filling hole 61 is connected to the through hole 31, the shrinking structure at the bottom of the filling nozzle 6 will be located in the expanded area of ​​the through hole 31, and can effectively prevent the adhesive from flowing out of the gap between the filling nozzle 6 and the bolt 3 at this time.

[0051] The elastic member 7 is installed inside the connecting member 5, and the two ends of the elastic member 7 are fixedly connected to the connecting member 5 and the filling nozzle 6 respectively, and has a tendency to drive the filling nozzle 6 to move to the limit position away from the corresponding nut 2 and maintain it. In this embodiment, the elastic member 7 is preferably a compression spring, and the elastic member 7 is sleeved outside the filling nozzle 6 for installation.

[0052] Reference Figure 4 and Figure 5 The blocking block 8 is a cylindrical structure as a whole, and the shape of the blocking block 8 is adapted to the through hole 31; before filling the through hole 31 with adhesive, the blocking block 8 will be located at the end of the through hole 31 away from the head of the bolt 3, and at this time the blocking block 8 forms a blockage in the through hole 31, which can effectively prevent foreign impurities from entering the through hole 31 through the opening of the through hole 31 at the tail of the bolt 3, thereby effectively reducing the probability that the through hole 31 is blocked by impurities and affects the subsequent filling of the through hole 31 with adhesive.

[0053] When the block 8 is in the through hole 31, the axis of the block 8 coincides with the axis of the through hole 31, the block 8 can move along the through hole 31 relative to the bolt 3, and the block 8 can remain in the through hole 31 to form a blockage during the movement along the through hole 31; in the process of filling the through hole 31 with adhesive, the force exerted on the block 8 by the adhesive entering the through hole 31 can drive the block 8 to move along the through hole 31 toward the head of the bolt 3; in this process, the friction between the block 8 and the inner wall of the through hole 31 will make the moving distance of the block 8 related to the amount of adhesive entering the through hole 31, so that the adhesive entering the through hole 31 can be filled in the through hole 31 first and then drive the block 8 to move, thereby effectively improving the reliability of the adhesive filling the through hole 31.

[0054] The positioning member 9 is elastic, has an overall annular structure, and is fixedly installed at one end of the through hole 31 away from the head of the bolt 3. When the block 8 is located at the end of the through hole 31 away from the head of the bolt 3, the block 8 will contact and resist against several positioning members 9 at the same time. At this time, several positioning members 9 will be in a state of being squeezed and deformed, so that the block 8 will be fixed in position here by the force of several positioning members 9; when the adhesive is filled into the through hole 31, the force of the adhesive entering the through hole 31 on the block 8 will drive the block 8 to overcome the force of several positioning members 9 and move toward the direction close to the head of the bolt 3, so that the block 8 is separated from the positioning of several positioning members 9. In this embodiment, the positioning member 9 is preferably made of rubber material; and preferably, two positioning members 9 are installed at the end of the through hole 31 away from the head of the bolt 3. When the block 8 is located at the end of the through hole 31 away from the head of the bolt 3, the two positioning members 9 will respectively apply force to both ends of the block 8 in the axial direction.

[0055] Reference Figure 4 and Figure 6 , the multiple second openings 43 on the support member 4 are opened at an angle relative to the radial direction of the support member 4, and the end of the second opening 43 close to the cavity 41 is an inclined upper end; when the block 8 moves along the through hole 31 toward the direction close to the head of the bolt 3, the block 8 will drive the gas originally in the through hole 31 to enter the cavity 41 and then leave through the multiple second openings 43. At this time, the gas leaving from the second openings 43 can be blown to the area of ​​the foundation floor around the support member 4 and close to the corresponding second openings 43, so that the dust in the above-mentioned area can be blown away, which is convenient for the subsequent adhesive to flow out to the above-mentioned area through the second openings 43 to form a connection with the foundation floor, thereby improving the connection strength between the support member 4 and the foundation floor through the adhesive.

[0056] Reference Figure 4 and Figure 7, the support member 4 is provided with a plug-in slot 44 on the cavity wall at the bottom of the cavity 41, and the end of the block 8 close to the head of the bolt 3 has a plug-in portion 81 adapted to the plug-in slot 44; when the block 8 moves to the extreme position in the direction close to the head of the bolt 3, the plug-in portion 81 will be plugged and matched with the plug-in slot 44, and the end of the block 8 away from the plug-in portion 81 will be located in the end of the through hole 31 close to the head of the bolt 3. At this time, the block 8 can form a support between the head of the bolt 3 and the support member 4, reducing the probability of changes in the positional relationship between the head of the bolt 3 and the support member 4, thereby improving the structural strength here.

[0057] Reference Figure 7 and Figure 8 , a plurality of shunt grooves 82 are provided at one end of the block 8 away from the plug-in portion 81, and the plurality of shunt grooves 82 are distributed in a circular array on the block 8 with the axis of the block 8 as the axis, and the number of the first through openings 42 and the second through openings 43 on the support member 4 is equal, and the plurality of shunt grooves 82 correspond to the plurality of first through openings 42 and the plurality of second through openings 43 one by one. When the plug-in portion 81 of the block 8 is plugged into the plug-in groove 44, the through hole 31 can communicate with the cavity 41 through the plurality of shunt grooves 82, that is, the adhesive filling the through hole 31 will enter the cavity 41 uniformly from all directions through the plurality of shunt grooves 82.

[0058] Reference Figure 6 and Figure 7 Furthermore, in order to enable the adhesive to flow into the cavity 41 under the guidance of the diverter groove 82 and then flow out smoothly through the corresponding first opening 42 and the second opening 43, that is, when the plug-in portion 81 of the blocking block 8 is plugged into the plug-in groove 44, the diverter groove 82 can be aligned with the corresponding first opening 42 and the second opening 43 along the same radial direction relative to the support member 4.

[0059] Reference Figure 7 and Figure 8 Preferably, the plug-in groove 44 is expanded in the direction close to the cavity 41, and the groove wall of the plug-in groove 44 has a guiding effect on the plug-in portion 81, which can guide the block 8 to achieve the plug-in fit of the plug-in portion 81 and the plug-in groove 44 in a determined position state; when the plug-in portion 81 is about to start plugging with the plug-in groove 44 when the position state of the block 8 is incorrect, the plug-in portion 81 will be blocked by the groove wall of the plug-in groove 44. At this time, the block 8 will continue to have the tendency of plugging the plug-in portion 81 with the plug-in groove 44 under the action of the adhesive that continues to enter the through hole 31. At the same time, the groove wall of the plug-in groove 44 will guide the plug-in portion 81 to drive the block 8 to rotate around its own axis until the block 8 completes the plug-in fit of the plug-in portion 81 and the plug-in groove 44 in the correct position state.

[0060] Reference Figure 6 and Figure 7At this time, the amount of adhesive entering the cavity 41 flowing out through the multiple first openings 42 will tend to be equal, and the amount flowing out through the multiple second openings 43 will also tend to be equal, so that the connection strength formed by the adhesive between the bottom and different positions of the peripheral side of the support member 4 and the foundation floor slab tends to be equal, thereby reducing the probability that the connection between the support member 4 and the foundation floor slab is easily damaged by a force in a certain direction due to uneven connection strength.

[0061] The implementation principle of the supporting structure of an assembled overhead floor in the embodiment of the present application is as follows: During the process of filling the adhesive, the filling nozzle 6 is firstly made to overcome the force of the elastic member 7 and move downward to the limit position so that the filling hole 61 and the through hole 31 remain connected, and then a certain amount of adhesive is filled into the through hole 31 through the filling nozzle 6; during the process of the adhesive entering the through hole 31, the blocking block 8 is firstly made to break away from the positioning of the plurality of positioning members 9, and then the blocking block 8 is driven to move downward along the through hole 31, and the blocking block 8 moves downward as the adhesive enters the through hole 31; When the blocking block 8 moves downward along the through hole 31, the gas in the through hole 31 is driven to enter the cavity 41 and then blown out through the plurality of second through holes 43, thereby blowing away the dust on the foundation floor slab near the second through holes 43, so that the subsequent adhesive flows out from the second through holes 43 and adheres to the foundation floor slab to form a connection; After the block 8 moves downward to the limit position, its plug-in portion 81 will be plugged into the plug-in groove 44, and then the adhesive in the through hole 31 will enter the cavity 41 evenly from multiple directions under the diversion of multiple diversion grooves 82, and then flow out evenly through multiple first through openings 42 and multiple second through openings 43, so that the outflowing adhesive is more evenly distributed, so as to improve the connection quality between the support member 4 and the foundation floor after the subsequent adhesive solidifies; Then, the filling nozzle 6 is moved back to its original position under the action of the elastic member 7, and then the adhesive is filled into the space in the clearance opening 11 located inside the connecting member 5 through the filling nozzle 6 until the adhesive overflows from the filling nozzle 6; After all the adhesives are solidified, the supporting structure can now safely and reliably support the floor layer 1 .

[0062] Embodiment 3: Reference Figure 1 and Figure 2 The present application embodiment discloses a leveling process, which is based on the support structure in embodiment 1 and is applied to the construction of the assembled overhead floor in embodiment 1, and includes the following steps: S1. Turn bolt 3 to form a space of required height below floor 1 and keep it level.

[0063] According to the height of the space required between the overhead floor and the basic floor, the multiple bolts 3 on the multiple floor layers 1 are rotated and adjusted so that the floor layer 1 can form an aperture of the required height between the floor and the basic floor and remain level under the support of multiple supporting structures.

[0064] S2, filling a certain amount of adhesive into the through hole 31.

[0065] A certain amount of adhesive is filled into the through hole 31 at the tail of the bolt 3, so that the adhesive fills the through hole 31 and the cavity 41, and flows out through the plurality of first through openings 42 and the plurality of second through openings 43; After the adhesive filled this time solidifies, the support member 4 is connected to the foundation floor slab through the adhesive, and the connection strength between the bolt 3 and the support member 4 is strengthened, thereby improving the position stability of the floor slab layer 1 and the structural strength of the supporting structure.

[0066] S3, filling the make way opening 11 with adhesive until the make way opening 11 is completely filled.

[0067] Fill the opening of the clearance hole 11 with adhesive until the clearance hole 11 is completely filled with adhesive. During this process, the adhesive in the clearance hole 11 will enter the plurality of grooves 21 of the nut 2; After the adhesive filled this time solidifies, connections are formed between the bolt 3 and the floor layer 1 and between the bolt 3 and the nut 2 through the adhesive, and the connection strength between the nut 2 and the floor layer 1 is strengthened, thereby improving the structural stability of the support structure after adjustment and the supporting effect of the support structure on the floor layer 1.

[0068] 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.
