Description

Technical Field

[0001] This invention relates to the field of building construction, and in particular to an outer panel corner keel structure and its construction method. Background Technology

[0002] Currently, prefabricated structures are widely used in the construction field. The outer panel is a prefabricated building structure that reinforces, supports, and beautifies the external corners of a building. It is usually composed of decorative panels and a keel structure. The keel structure is fixed to the wall, and then the outer panel is fixed to the keel structure, which can achieve the reinforcement, support, and beautification of the external corners of the building.

[0003] The keel structure in related technologies typically includes two right-angled supporting keels. The two ends of each supporting keel are fixed by supporting square steel, and clearance holes are formed between the two supporting keels. The two supporting keels are then tightly attached to the wall, and two through-wall bolts pre-embedded in the wall are passed through the clearance holes. A clamping nut is then used to connect the keel to the through-wall bolts, and the clamping nut is used to press and fix the supporting keel to the wall, thus completing the assembly of the keel structure.

[0004] However, simply using the tightening nuts to press the support keel onto the wall, relying solely on the friction between the support keel and the wall to constrain the position of the support keel, is prone to lateral displacement of the support keel. In other words, the support keel will shift away from the external corner of the wall, making it difficult for the support keel to fit tightly against the wall. This can easily cause misalignment between two adjacent decorative panels, resulting in uneven external corners of the wall, which needs improvement. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an outer panel corner keel structure and its construction method, which can improve the limiting effect of the keel structure, so that the keel structure can be closely attached to the wall, reduce the risk of misalignment between two adjacent decorative panels, and ensure the straightness of the wall corner.

[0006] In a first aspect, the present invention provides an outer panel corner keel structure, comprising two right-angled support keels, the two ends of the two support keels being welded and fixed by support square steel, and a clearance hole being formed between the two support keels. Each of the two support square steels is threaded with a tightening screw, one end of the two tightening screws near the right-angle position of the support keel being used to abut against the corresponding through-wall bolt, and the other end of each is provided with a tightening part.

The inner wall of the limiting notch is provided with a threaded groove, which matches the external thread on the through-wall bolt so that the thread on the through-wall bolt can be inserted into the threaded groove.

[0009] In a preferred embodiment, the present invention can be further configured such that: the rotating part includes a rotating shell fixed to the clamping block, a rotating disk is rotatably connected inside the rotating shell, a rotating hole is provided on the rotating shell, the inner diameter of the rotating hole is smaller than the outer diameter of the rotating disk, and the clamping screw passes through the rotating hole and is coaxially and fixedly connected to the rotating disk.

[0010] In a preferred embodiment, the present invention can be further configured as follows: the top of the clamping block is provided with a receiving groove, an anti-retraction column is vertically slidably connected in the receiving groove, an anti-retraction rack is provided on the top of the anti-retraction column, an anti-retraction groove is provided on the inner wall of the top side of the clearance hole, and a driving member is provided on the clamping block. When the clamping block abuts against the through-wall bolt, the driving member is used to control the anti-retraction column to move upward and to make the anti-retraction rack engage with the anti-retraction groove.

[0011] In a preferred embodiment, the present invention can be further configured as follows: the side wall of the clamping block is provided with a driving hole communicating with the receiving groove; the driving component includes a driving rod that is horizontally slidably connected in the driving hole; the end of the driving rod is provided with a driving inclined surface; and the bottom of the anti-retraction column is provided with a guide inclined surface that matches the driving inclined surface.

[0012] The rotating disk abuts against the driving rod, and the rotating disk can enter the driving hole and push the driving rod to move horizontally, so that the anti-reverse column moves upward under the action of the driving inclined surface and the guide inclined surface.

[0013] In a preferred embodiment, the present invention can be further configured such that: a shearing rod is horizontally fixedly connected inside the drive hole, a shearing hole is provided through the drive rod, and the shearing rod passes through the shearing hole; a shearing blade is fixedly connected to the inner wall of the shearing hole facing the rotating disk, the shearing blade abuts against the shearing rod and is used to cut the shearing rod.

[0014] In a preferred embodiment, the present invention can be further configured such that: an elastic anti-reverse helical tooth is fixedly connected to the driving inclined surface, and multiple anti-reverse tooth grooves are provided on the guide inclined surface, and the anti-reverse helical tooth can be engaged in any of the anti-reverse tooth grooves.

[0015] In a preferred embodiment, the present invention may be further configured such that: the tightening part includes a support base and a tightening sleeve, the support base is connected to the tightening screw, the tightening sleeve is connected to the support base, the axis of the tightening sleeve is perpendicular to the axis of the tightening screw, and a rod-shaped tightening tool protrudes through the tightening sleeve.

[0017] The support base is rotatably connected to the tightening sleeve. A ratchet and tooth one-way limiting mechanism is provided between the support base and the tightening sleeve. The support base and the tightening sleeve can rotate synchronously in the tightening direction of the tightening screw.

[0018] Secondly, the present invention provides a construction method for an outer leaf plate external corner keel structure, comprising the following steps:

[0019] S1, tighten the two supporting keels against the wall respectively, and make the two through bolts pass through the clearance holes respectively;

[0021] S2, connect the fastening nut to the corresponding through-wall bolt, tighten the fastening nut, and press the fastening nut firmly against the wall.

[0022] In summary, the present invention has the following beneficial effects:

[0023] 1. By using two tightening screws to abut against the corresponding through-wall bolts, the keel structure can be tightly attached to the wall under the tension of the two tightening screws, which effectively improves the limiting effect of the keel structure, reduces the risk of lateral displacement of the keel structure, and thus reduces the risk of misalignment between two adjacent decorative panels, so as to ensure the straightness of the wall's external corner;

[0024] 2. By setting a tightening block at the end of the tightening screw, and setting a limiting notch on the tightening block for the through-wall bolt to be inserted, the contact area and connection stability between the tightening screw and the through-wall bolt are increased, so as to ensure the tightening effect on the keel structure and thus improve the structural stability;

[0025] 3. When the clamping block is pressed against the through-wall bolt, the driving component can control the anti-reverse column to move upward and make the anti-reverse rack mesh with the anti-reverse groove, thereby realizing the anti-reverse locking function of the clamping block and the clamping screw, so as to improve the reliability of the keel structure and ensure the stability of the building structure.

[0032] The present invention will be further described in detail below with reference to the accompanying drawings.

[0033] like Figure 1 , Figure 2 The following is an embodiment of the present invention, which discloses an outer panel corner keel structure, including two right-angled support keels 1. The two ends of the two support keels 1 are respectively welded and fixed by support square steel 2, and a clearance hole 3 is formed between the two support keels 1.

[0034] Reference Figure 1 , Figure 2 Two supporting square steels 2 are threaded with tightening screws 4. One end of each tightening screw 4 near the right angle of the supporting keel 1 is used to tighten the corresponding through-wall bolts, and the other end is provided with a tightening part 5.

[0035] By using two tightening screws 4 to abut against the corresponding through-wall bolts, the keel structure can be tightly attached to the wall under the tension of the two tightening screws 4, which effectively improves the limiting effect of the keel structure, reduces the risk of lateral displacement of the keel structure, and thus reduces the risk of misalignment between two adjacent decorative panels, so as to ensure the straightness of the wall's external corner.

[0036] Reference Figure 1 , Figure 3 A tightening block 6 is provided at one end of the tightening screw 4 near the right angle position of the supporting keel 1. The tightening block 6 is horizontally slidably connected to the relief hole 3, and the tightening block 6 and the corresponding tightening screw 4 are rotatably connected through the rotating part 7. A limiting notch 8 is provided on the side of the tightening block 6 away from the corresponding tightening screw 4. The through-wall bolt can be inserted into the limiting notch 8. The inner wall of the limiting notch 8 is provided with a threaded groove 9. The threaded groove 9 matches the external thread on the through-wall bolt so that the thread on the through-wall bolt can be inserted into the threaded groove 9.

[0037] When the tightening screw 4 is rotated forward by the tightening part 5, the through-wall bolt can be inserted into the limiting notch 8, and the threads on the through-wall bolt can be inserted into the thread groove 9, so as to increase the contact area between the through-wall bolt and the tightening screw 4, and also improve the connection stability between the two, so as to ensure the tightening effect of the tightening screw 4 on the keel structure.

[0038] Reference Figure 3 , Figure 4 The rotating part 7 includes a rotating shell 71 fixed on the clamping block 6. A rotating disk 72 is rotatably connected inside the rotating shell 71. A rotating hole 73 is provided on the rotating shell 71, and the inner diameter of the rotating hole 73 is smaller than the outer diameter of the rotating disk 72. At the same time, the clamping screw 4 passes through the rotating hole 73 and is coaxially fixedly connected to the rotating disk 72 so that the clamping screw 4 can drive the rotating disk 72 to rotate smoothly.

[0039] Reference Figure 3 , Figure 4 The top of the clamping block 6 is provided with a receiving groove 10, and an anti-retraction column 11 is vertically slidably connected in the receiving groove 10. The top of the anti-retraction column 11 is provided with an anti-retraction rack 12, and the inner wall of the top side of the clearance hole 3 is provided with an anti-retraction groove 13. At the same time, a driving component 14 is provided on the clamping block 6. When the clamping block 6 abuts against the through bolt, the driving component 14 is used to control the anti-retraction column 11 to move upward and make the anti-retraction rack 12 engage with the anti-retraction groove 13, thereby realizing the anti-retraction locking function of the clamping block 6 and the clamping screw 4, so as to improve the reliability of the keel structure.

[0040] Reference Figure 3 , Figure 4The side wall of the clamping block 6 has a drive hole 15 that communicates with the receiving groove 10. The drive component 14 includes a drive rod 141 that is horizontally slidably connected in the drive hole 15. The end of the drive rod 141 is provided with a drive inclined surface 142, and the bottom of the anti-retraction column 11 is provided with a guide inclined surface 143 that matches the drive inclined surface 142. The rotating disk 72 abuts against the drive rod 141, and the rotating disk 72 can enter the drive hole 15 and push the drive rod 141 to move horizontally, so that the anti-retraction column 11 moves upward under the action of the drive inclined surface 142 and the guide inclined surface 143. This design enables the anti-retraction column 11 to move automatically when the clamping screw 4 is clamped to the through bolt, improving the linkage effect between the components.

[0041] Reference Figure 3 , Figure 4 A shearing rod 16 is horizontally fixedly connected inside the drive hole 15. A shearing hole 17 is provided through the drive rod 141, and the shearing rod 16 passes through the shearing hole 17. A shearing blade 18 is fixedly connected to the inner wall of the shearing hole 17 facing the rotating disk 72. The shearing blade 18 abuts against the shearing rod 16 and is used to cut the shearing rod 16.

[0042] When the tightening screw 4 is tightened against the through-wall bolt, and as the tightening screw 4 continues to tighten, the shearing rod 16 is cut by the shearing blade 18. Then, the tightening block 6 continues to advance, and the anti-reverse column 11 will move upward. This design ensures that the anti-reverse column 11 will not move upward when the operator begins to tighten the tightening screw 4, thus guaranteeing that the tightening block 6 can slide smoothly and avoiding the risk of the anti-reverse column 11 moving upward when the tightening screw 4 is not tightened against the through-wall bolt.

[0043] Reference Figure 3 , Figure 4 An elastic anti-reverse helical tooth 19 is fixedly connected to the drive inclined surface 142, and multiple anti-reverse tooth grooves 20 are provided on the guide inclined surface 143. The anti-reverse helical tooth 19 can be inserted into any anti-reverse tooth groove 20, thereby realizing the anti-reverse limiting capability of the drive rod 141, so as to ensure that the anti-reverse rack 12 and the anti-reverse tooth groove 13 maintain a tight meshing state and improve locking stability.

[0044] Furthermore, the drive rod 141 has a tendency to move backward under the action of the drive inclined surface 142 and the guide inclined surface 143, while the tightening screw 4 abuts against the drive rod 141, so that the threads between the tightening screw 4 and the supporting square steel 2 can be tightly abutted, effectively improving the anti-reverse locking ability of the tightening screw 4.

[0045] Reference Figure 3 , Figure 5The tightening part 5 includes a support base 51 and a tightening sleeve 52. The support base 51 is connected to the tightening screw 4, and the tightening sleeve 52 is connected to the support base 51. The axis of the tightening sleeve 52 is perpendicular to the axis of the tightening screw 4, and the tightening sleeve 52 allows a rod-shaped tightening tool to pass through, so that the operator can quickly rotate the tightening screw 4.

[0046] Reference Figure 3 , Figure 5 The tightening screw 4 is movably connected to the support base 51. A hexagonal prism connecting rod 21 is fixedly connected to the end of the tightening screw 4. The support base 51 is provided with a connecting groove 22 for the connecting rod 21 to be inserted and matched with the connecting rod 21, so that the support base 51 can drive the tightening screw 4 to rotate.

[0047] Reference Figure 3 , Figure 5 The support base 51 is rotatably connected to the tightening sleeve 52. A ratchet and tooth one-way limiting mechanism is provided between the support base 51 and the tightening sleeve 52. The support base 51 and the tightening sleeve 52 can rotate synchronously in the tightening direction of the tightening screw 4.

[0048] When the operator controls the tightening sleeve 52 to rotate a certain angle using a tool, and tightens the top screw 4 to a certain extent, the tool can be rotated in the opposite direction. At this time, under the action of the ratchet and tooth one-way limiting mechanism, the top screw 4 will not rotate. Because the tightening sleeve 52 is relatively close to the wall, the tightening tool cannot rotate a full circle. This design allows the operator to quickly tighten the top screw 4 without having to pull out the tightening tool.

[0049] Embodiments of the present invention also disclose an outer leaf plate external corner keel structure and its construction method, including the following steps:

[0050] S1, press the two supporting keels 1 against the wall respectively, and make the two through bolts pass through the relief holes 3 respectively.

[0051] S2, by rotating the corresponding tightening screw 4 through the tightening part 5, the tightening screw 4 is pressed against the corresponding through-wall bolt.

[0052] S2, connect the fastening nut to the corresponding through-wall bolt, tighten the fastening nut, and press the fastening nut to the wall to press the support keel 1.

[0053] The specific embodiments are merely illustrative of the present invention and are not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
