[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to Figure 1-8 , the present invention provides a technical solution: a construction member splicing joint sealing construction connection device with strong sealing performance, including a first wall 1, an installation groove 2, an installation block 3, a second wall 4, a first protection plate 5, a first protection pad 6, an installation mechanism 7, a first anti-inclination mechanism 8, a second anti-inclination mechanism 9, a second protection plate 10, a second protection pad 11, a limiting bolt 12 and a convex block 13. For the first wall 1, installation grooves 2 are equidistantly opened inside the middle end of the first wall 1, and installation blocks 3 are correspondingly clamped and connected inside the installation grooves 2, wherein the upper end of the installation block 3 is fixedly connected to the bottom end of the second wall 4;

[0045] For the first protection plate 5, the first protection plate 5 is bolted symmetrically about the longitudinal central axis of the second wall 4 to the upper end of the first wall 1, and a first protection pad 6 is inlaid and connected to the inner end of the first protection plate 5, wherein the inner end of the first protection pad 6 is in contact with the outer wall of the second wall 4;

[0046] For the installation mechanism 7, the installation mechanism 7 is arranged on the first wall 1, and the installation mechanism 7 includes a threaded rod 701, a connection platform 702, an adjusting block 703, a first track 704, a limiting plate 705, a connection groove 706 and a limiting groove 707;

[0047] The first anti-tilt mechanism 8, the first anti-tilt mechanism 8 is arranged at the outer end of the first protection plate 5, and the first anti-tilt mechanism 8 includes a support column 801, a mounting seat 802, a connecting shaft 803, a motor 804, a disc 805, a first limiting rod 806 and an adjusting member 807. At the same time, the support column 801 is bolted to the upper outer end of the first protection plate 5;

[0048] The second anti-tilt mechanism 9, the second anti-tilt mechanism 9 is arranged at the upper end of the mounting seat 802, and the second anti-tilt mechanism 9 includes a second track 901, a connecting strip 902, a pressing strip 903 and a second limiting rod 904, wherein the second track 901 is opened inside the upper end of the mounting seat 802.

[0049] When using the construction member splicing joint sealing construction connection device with strong sealing performance, combined with Figure 1 、 Figure 3 、 Figure 5 and Figure 7 ,Place the second wall 4 at the upper middle end of the first wall 1, snap the mounting blocks 3 fixedly connected at equal intervals at the bottom end of the second wall 4 into the corresponding mounting grooves 2 inside to prevent the second wall 4 from tipping over at the upper end of the first wall 1. Place the first protection plates 5 at the left and right ends of the first wall 1, so that the first protective pads 6 embedded and connected at the inner ends of the left and right groups of first protection plates 5 closely fit on the left and right side walls at the lower end of the second wall 4, and limit the outer ends of the first protection plates 5 to the upper end of the first wall 1 by bolts;

[0050] The structure composed of the support column 801, the mounting seat 802, the connecting shaft 803, the motor 804, the disc 805, the first limiting rod 806 and the adjusting member 807 and the structure composed of the second track 901, the connecting strip 902, the pressing strip 903 and the second limiting rod 904 prevent the second wall 4 from tilting on the first wall 1. Place the support columns 801 symmetrically left and right at the middle parts of the left and right ends of the first wall 1, and limit the position of the support columns 801 at the upper end of the first protection plate 5 by bolts. When the motor 804 works, it drives the connecting shaft 803 to rotate. When the connecting shaft 803 rotates, it drives the disc 805 nested and connected inside the front end of the mounting seat 802 to rotate. Since the connection point between the first limiting rod 806 and the disc 805 is not collinear with the center of the disc 805, when the disc 805 rotates, it drives the first limiting rod 806 to rotate, so that the first limiting rod 806 clamped at the lower middle end of the adjusting member 807 drives the lower end of the adjusting member 807 to rotate at the front lower end of the mounting seat 802, making the adjusting member 807 rotate inward;

[0051] When the adjusting member 807 rotates inward, the second limiting rod 904 engaged with the upper end of the adjusting member 807 enables the adjusting member 807 to push the extrusion bar 903 inward, allowing the connecting bar 902 to slide inward inside the second track 901 at the corresponding position until the inner end of the extrusion bar 903 is tightly against the left and right side walls of the upper end of the second wall 4. At this time, the motor 804 stops working, and the second wall 4 is easily supported by the left and right groups of extrusion bars 903 to prevent the second wall 4 from tilting when the joint is sealed. Since the lower end of the extrusion bar 903 is integrally connected with the connecting bar 902 with a "T"-shaped structure in the longitudinal section viewed from the left, and the connecting bar 902 is slidably connected to the inside of the second track 901, the connecting bar 902 will not separate from the inside of the second track 901.

[0052] Combination Figure 1 , Figure 2 and Figure 6 , place the second protection plate 10 on the left and right ends of the first protection plate 5, so that the inner end of the second protection pad 11 is tightly against the left and right side walls of the lower end of the second wall 4, and the position of the second protection plate 10 is limited by the structure composed of the threaded rod 701, the connecting platform 702, the adjustment block 703, the first track 704, the limit plate 705, the connecting groove 706 and the limit groove 707. The second protection plate 10 is placed on the upper end of the first protection plate 5, and the threaded rods 701 arranged at equal intervals correspond to the corresponding connecting grooves 706, and the disc 805 enters the inside of the connecting groove 706. The threaded rod 701 is rotated to make it descend on the second protection plate 10, and the threaded rod 701 is rotated on the upper end of the connecting platform 702;

[0053] Since the limit plate 705 forms a sliding structure through the adjustment block 703 and the connecting platform 702, the threaded rod 701 drives the connecting platform 702 to descend, so that the adjustment blocks 703 at the left and right ends of the connecting platform 702 slide downward inside the first track 704 at the corresponding position, so that the lower end between the left and right groups of the limit plate 705 rotates, and the inclination angle of the limit plate 705 is increased until the upper end of the limit plate 705 is nested in the limit groove 707 at the corresponding position. The position of the second protective plate 10 on the first protective plate 5 is limited by the limit plate 705 and the limit groove 707, so that the protective plate can be installed on the first wall 1 to seal the joint;

[0054] Combination Figure 1 , Figure 4 and Figure 8When the second protection plates 10 are respectively placed on the left and right sides of the second wall body 4, the installation mechanisms 7 arranged at equal intervals limit the positions of the second protection plates 10. Since the bottom ends of the second protection plates 10 are in a concave-convex structure, and the concave-convex structure fits with the convex blocks 13, the concave-convex structures at the bottom ends of the second protection plates 10 are engaged inside the convex blocks 13 at corresponding positions. The concave-convex structures at the bottom ends of the second protection plates 10 and the uniformly arranged convex blocks 13 increase the friction between the second protection plates 10 and the first protection plates 5;

[0055] Let the inner ends of the second protection plates 10 with an "L"-shaped cross-section be located on the left and right side walls at the lower end of the second wall body 4. Let the limit bolts 12 be installed at equal intervals inside the upper ends of the second protection plates 10. The upper ends of the second protection plates 10 are installed on the second wall body 4 through the limit bolts 12, so that the inner ends of the second protective pads 11 and the inner ends of the first protective pads 6 are both closely attached to the second wall body 4 and the first wall body 1. The first protective pads 6 and the second protective pads 11 are both made of rubber and have a certain elasticity. Therefore, the first protection plates 5, the first protective pads 6, the second protection plates 10 and the second protective pads 11 increase the sealing performance between the splicing joints of the first wall body 1 and the second wall body 4. This is the working principle of the construction component splicing joint sealing construction connection device with strong sealing performance.

[0056] The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the descriptions in the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, welding, etc. that are mature in the prior art.

In addition, the circuit connection adopts the conventional connection method in the prior art, which will not be elaborated here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
