Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a corbel device under a steel structure corridor. Background Technology

[0002] A connecting corridor is a long and narrow passageway inside or between buildings, usually connecting different rooms, floors or buildings. During the construction of a connecting corridor, the main frame of the building is usually equipped with a corbel support component. A corbel is another name for a beam support. Its function is to be a support under the beam in a mixed structure, and its function is to distribute the force of the beam support to the load-bearing structure below.

[0003] The existing corbel support system for connecting corridors has the following problems during use: The existing corbel support columns used to support the corridor roof mainly achieve support for the beams by contacting the bottom two sets of support plates. Since the support plates of the corbel support columns are mostly connected to the columns using mortise and tenon joints or bolts, the installation structure is relatively fixed, making it inconvenient to adjust the support height. Furthermore, over time, the contact area between the corridor beams and the corbel support columns may be corroded or affected by temperature changes, potentially causing gaps to form between the support plates of the corbel support columns and the corridor beams. This is especially true for some wooden corridor roof structures, leading to a decrease in the supporting effect of the corbel support columns on the corridor roof beams and posing a risk of collapse. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides a corbel device for steel structure corridors, which solves the problems of existing corbel support columns, which are mostly fixed in installation structure, making it inconvenient to adjust the support height, and are easily affected by the external environment during use.

[0005] To achieve the above objectives, the present invention provides a corbel device under a steel structure connecting corridor, comprising:

[0006] The corbel support assembly includes a column forming an installation space inside, two bases symmetrically installed at the bottom of the column along the height direction, and two support plates slidably installed at one end of the column relative to the two bases for supporting the steel structure corridor.

[0007] The sliding support mechanism includes two protective plates that are vertically and symmetrically arranged on both sides of the column adjacent to the support plate. The two protective plates are spliced ​​together and surround the outside of the column, and their two ends along the height direction are respectively engaged with the support plate and the base.

[0008] An adaptive lifting position adjustment mechanism for raising and lowering the protective plates includes a floating plate that is movably disposed above the base and fixedly connected to each of the two protective plates.

[0009] Preferably, adaptive adjustment grooves are symmetrically provided on both sides of the column, and a rigid slider is slidably installed in the adaptive adjustment groove, and the rigid slider is fixedly connected to the support plate.

[0010] Preferably, the protective plate forms notches at both ends along the height direction corresponding to the support plate and the base, and the notches are respectively provided with slots for engaging the support plate and the base.

[0011] Preferably, a rotating gear is rotatably mounted on the base, and a conical screw cylinder is coaxially fixedly connected to the rotating gear. The smaller diameter end of the conical screw cylinder is telescopically inserted into the side of the floating plate opposite to the protective plate, and a floating slot is correspondingly opened on the floating plate for the conical screw cylinder to be inserted.

[0012] Preferably, a support block for fixed connection with the steel structure corridor is elastically installed on the support plate, and a rigid rack that meshes with the rotating gear is fixedly installed on one end of the support block relative to the steel structure corridor, and one end of the rigid rack relative to the support block passes through the support plate and is fixedly connected to the base.

[0013] Preferably, the support block includes a top plate for fixed installation on the top of the crossbeam of the steel structure corridor, a bottom plate disposed on the side of the support block near the support plate and for connecting with the lower edge of the crossbeam of the steel structure corridor, and an elastic laminated plate elastically installed between the top plate and the bottom plate.

[0014] Preferably, it also includes an auxiliary filling component, which includes a knob that is rotatably inserted into the column along a direction perpendicular to the height of the column, an inner disc that is coaxially rotatably connected to the knob and located within the installation space, and a pressing protrusion fixedly installed on the edge of the inner disc along its circumferential direction. A rubber storage cylinder that contacts the pressing protrusion is provided at the top of the column along its height direction within the installation space, and an outer conduit that is fixedly installed on the top of the rubber storage cylinder and connected to the support plate.

[0015] Preferably, the two protective plates form two symmetrical arc-shaped slots corresponding to the knob for the knob to pass through.

[0016] Preferably, the support plate includes a plate body with an installation groove on its surface and a pressure plate housed in the installation groove. The installation groove has two sets of flow guiding channels symmetrically opened on both sides along its width direction. The two sets of flow guiding channels are uniformly provided with diversion holes that communicate with the installation groove. The diversion holes are connected to the outer conduit.

[0017] Preferably, the two protective plates are spliced ​​together to form a splicing groove, and the width of the splicing groove is the same as the width of the column.

[0018] By adopting the above technical solution, the present invention has the following beneficial effects:

[0019] 1) The support plate at the top of the corbel support assembly can provide support for the crossbeams of the connecting corridor, and the sliding support mechanism on both sides can reinforce the support plate, which can greatly improve the support strength of the support plate.

[0020] 2) An adaptive lifting position adjustment mechanism is installed between the connecting corridor beam and the sliding support mechanism. When the wooden connecting corridor beam is corroded or gaps are caused by temperature, the height of the sliding support mechanism can be adjusted so that the support plate can always be in contact with the bottom of the connecting corridor beam, thus achieving the purpose of adaptive reinforcement and stability.

[0021] 3) By using the auxiliary filling component built into the top of the corbel support assembly, the sealing and stability of the contact position between the support plate and the crossbeam of the connecting corridor can be ensured by filling when the gap between the crossbeam and the support plate is large.

Detailed Implementation

[0031] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0032] The technical problem this invention aims to solve is that existing corbel support columns used for supporting the roof of connecting corridors mainly achieve support for the crossbeams of the corridor through contact between two sets of support plates at the bottom. Since the support plates of the corbel support columns are mostly connected to the columns using mortise and tenon joints or bolts, the installation structure is relatively fixed and it is inconvenient to adjust the support height. Furthermore, during long-term use, the contact area between the crossbeams and the corbel support columns may be affected by corrosion or temperature changes, potentially leading to gaps between the support plates of the corbel support columns and the crossbeams. This is especially problematic for wooden structures like connecting corridors, causing a decrease in the supporting effect of the corbel support columns on the crossbeams and posing a risk of collapse. This invention provides a corbel device under a steel structure connecting corridor that achieves self-adaptive reinforcement and stability, greatly improving the stability of the support for the crossbeams of the connecting corridor.

[0033] Please see Figures 1 to 6As shown, the present invention provides a corbel device under a steel structure corridor, including a corbel support assembly, a sliding support mechanism, an adaptive lifting position adjustment structure, and an auxiliary filling assembly. The corbel support assembly includes a column 2 forming an installation space 1 inside, two bases 6 symmetrically installed at the bottom of the column 2 along the height direction, and two support plates 3 slidably installed on the column 2 at one end relative to the bases 6 and used to support the top beam of the steel structure corridor. Preferably, two adaptive adjustment grooves 4 are symmetrically opened on both sides of the column 2. Rigid sliders 5 are slidably installed in the adaptive adjustment grooves 4, and the rigid sliders 5 are fixedly connected to the support plates 3. In this embodiment, the support plates 3 are made of steel profiles. The upper surface of the support plates 3 is horizontally arranged, and the lower surface is inclined. The height of the lower surface on the side away from the column 2 is greater than the height on the side closer to the column 2. The bases 6 have the same structure as the support plates 3 and are distributed in a mirror image.

[0034] Furthermore, the sliding support mechanism includes two protective plates 7 that are symmetrically and liftably disposed on both sides of the column 2 adjacent to the support plate 3. The two protective plates 7 are spliced ​​together and surround the outside of the column 2. The two ends along the height direction are divided into two halves and engaged with the support plate 3 and the base 6. It should be noted that in this embodiment, the protective plates 7 are made of steel. The two ends of the protective plates 7 along the height direction respectively form notches 8 corresponding to the support plate 3 and the base 6. The notches 8 are respectively provided with slots 9 for engaging the support plate 3 and the base 6. The two protective plates 7 are spliced ​​together to form a splicing groove 26. The width of the splicing groove 26 is the same as the width of the column 2. Therefore, the front and rear sides of the column 2 can be supported and reinforced.

[0035] Please see Figure 1 , Figures 3 to 5 An adaptive lifting position adjustment mechanism is used to lift the protective plates 7, including floating plates 17 that are movably mounted above the base 6 and fixedly connected to the two protective plates 7 respectively, such as... Figure 1 , Figure 3 and Figure 5 As shown, a fixing plate 13 is fixedly installed on the base 6. The fixing plate 13 is built into the base 6. A rotating gear 14 is actively installed on the fixing plate 13. The rotating gear 14 has a retaining tooth 18. A screw 15 is coaxially connected to one end of the rotating gear 14 near the column 2. A conical screw cylinder 16 is threadedly connected to the other end of the screw 15 away from the rotating gear 14. Preferably, a threaded groove 19 corresponding to the screw 15 is opened in the conical screw cylinder 16. The smaller diameter end of the conical screw cylinder 16 is telescopically inserted into the side of the floating plate 17 relative to the protective plate 7. A floating slot 20 for the conical screw cylinder 16 to be inserted is opened on the side of the floating plate 17 relative to the protective plate 7. It should be noted that, as Figure 3As shown, in this embodiment, the conical screw barrel 16 has an overall conical structure and the diameter of the end near the floating plate 17 is smaller than the diameter of the end near the screw 15. The conical screw barrel 16 is in contact with the floating groove 20. Two sets of limiting protrusions 27 are machined on both sides of the conical screw barrel 16. The lower end of the column 2 is provided with a groove that matches the shape of the conical screw barrel 16. When the screw 15 acts inside the conical screw barrel 16, the conical screw barrel 16 will not rotate and will move along the groove, thereby adjusting the height of the floating plate 17.

[0036] Furthermore, a support block 11 for fixed connection with the top beam of the steel structure corridor is elastically installed on the support plate 3. A rigid rack 12 that meshes with the locking teeth is fixedly installed on one end of the support block 11 relative to the top beam of the steel structure corridor, and the rigid rack 12 relative to the support block 11 passes through the support plate 3 and is fixedly connected to the base 6 through the fixing plate 13.

[0037] Furthermore, such as Figure 4 As shown, the support block 11 includes a top plate 28 for fixed installation on the top of the crossbeam of the steel structure corridor, a bottom plate 30 located on the side of the support block 11 near the support support plate 3 and for connecting with the lower edge of the crossbeam of the steel structure corridor, and an elastic laminated plate 29 elastically installed between the top plate 28 and the bottom plate 30. The elastic laminated plate 29 passes through the crossbeam of the steel structure corridor. In this embodiment, the elastic laminated plate 29 is made of elastic metal material and has a laminated structure. When the bottom of the crossbeam of the steel structure corridor is corroded and the thickness decreases, resulting in gaps, the elastic force of the elastic laminated plate 29 can pull the bottom plate 30 upward and keep it in contact with the bottom of the crossbeam, thereby improving the power to adjust the adaptive lifting position adjustment mechanism.

[0038] Please see Figure 1 and Figure 6 As shown, the auxiliary filling component includes a knob 21 that rotates and is inserted into the column 2 along the height direction perpendicular to the column 2, an inner plate 22 that is coaxially rotatably connected to the knob 21 and located in the installation space 1, and an extrusion protrusion 23 that is fixedly installed on the edge of the inner plate 22 along the circumferential direction. A rubber storage cylinder 24 that contacts the extrusion protrusion 23 is provided at the top of the column 2 along the height direction in the installation space 1. An outer guide tube 25 that is connected to the support plate 3 is fixedly installed on the top of the rubber storage cylinder 24. Preferably, two arc-shaped slots 10 are formed on the protective plate 7 corresponding to the knob 21 and are used for the knob 21 to pass through. Therefore, when the two sets of arc-shaped slots 10 are spliced, the knob 21 is located between the two sets of arc-shaped slots 10, which can improve the overall aesthetics.

[0039] Furthermore, in this embodiment, the top of the rubber storage cylinder 21 is provided with four external conduits 25, and two adjacent sets of external conduits 25 are connected to a support plate 3 box.

[0040] Furthermore, please refer to Figure 5 As shown, the support plate 3 includes a plate body 32 with an installation groove 31 on its surface and a pressure plate 32 housed in the installation groove 31. The installation groove 31 has two sets of flow channels 34 symmetrically arranged on both sides along its width. The two sets of flow channels 34 are evenly provided with diversion holes 35 that communicate with the installation groove 31. The diversion holes 35 are connected to the outer guide tube 25. The operator can also rotate the inner plate 22 by turning the knob 21, so that the extrusion protrusion 23 abuts against the bottom of the rubber storage cylinder 24 and the filling colloid stored in the rubber storage cylinder 24 flows out along the outer guide tube 25 and is introduced into the installation groove 31 through the diversion hole 35, so that the pressure plate 33 floats up and contacts the crossbeam, thereby sealing the gap.

[0041] The specific use of the corbel device under the steel structure connecting corridor of the present invention includes the following steps:

[0042] Step 1: Installation Phase

[0043] When it is necessary to fix the corbel device under the connecting corridor, the workers can pre-open a foundation pit at the construction location of the connecting corridor, then insert the column 2 below the base 6 into the foundation pit and pour concrete for reinforcement and fixation. When the connecting corridor beam is erected, the contact part between the connecting corridor beam and the support plate 3 is pre-grooved, and the support block 11 is placed into the groove. The connecting corridor beam is then horizontally placed on two sets of support plates 3. After placement, the workers place two sets of protective plates 7 at the front and rear of the column 2 respectively, so that the protection The upper and lower end slots 9 of plate 7 are respectively inserted into the side edges of support plate 3 and base 6, and the protective plate 7 is pushed inward. During the inward movement, the top of the steel protective plate 7 floats upward and pushes the support plate 3 to move longitudinally along the adaptive adjustment groove 4. After the connecting corridor beam is raised to an appropriate height, two sets of fixing bolts are symmetrically inserted into the fixing bolt holes 36 on both sides of support plate 3 and base 6, so that the inner end of the fixing bolts blocks and limits the steel protective plate 7. Then the support block 11 is welded to the rigid rack 12.

[0044] Step Two: Post-Maintenance Phase

[0045] When the lower surface of the connecting corridor beam reduces in thickness due to corrosion or temperature during use, creating a gap between it and the support plate 3, the elastic laminated plate 29 pulls the upper edge of the base plate 30 and pulls the rigid rack 12 upward. During the upward movement of the rigid rack 12, the rotating gear 14 and the screw 15 rotate, the conical screw cylinder 16 moves towards the column 2, and the floating plate 17 moves upward, thereby driving the two sets of steel protection plates 7 to move upward, which in turn causes the support plate 3 to move upward and re-contact the lower edge of the beam. At this time, the staff can adjust the fixing bolts used to cover and limit the steel protection plates 7. When the upward position of the support plate 3 reaches the limit value, the staff can also turn the knob 21 to drive the inner plate 22 to rotate, so that the extrusion protrusion 23 abuts against the bottom of the rubber storage cylinder 24 and the filling colloid stored in the rubber storage cylinder 24 flows out along the outer guide tube 25 and fills the installation groove 31, so that the pressure plate 33 floats up and contacts the beam.

[0046] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
