[0027] Example: See Figure 1-6 The present invention provides a technical solution: a corridor structure with high stability, including a corridor 1, which is arranged between two buildings 2 and is used to connect the two buildings. A steel section 5 is arranged on the inner side of the pouring beam 3 of the building 2, and the steel section 5 is fixed on the pouring beam 3. The steel section 5 is provided with a plurality of pieces and a connecting base connected to the corridor 1 is formed with the plurality of pouring beams 3. The base has good stability and a firm structure. A connecting sleeve 4 is arranged on the outer side of the pouring beam 3. Connecting plates 11 matching the connecting sleeve 4 are welded at both ends of the corridor 1. The corridor 1 is positioned and connected by inserting the connecting plate 11 on the connecting sleeve 4. The top and bottom of the connecting plate 11 are A plurality of through rectangular plug holes 14 are provided, and a plurality of U-shaped plug plates 13 matching the rectangular plug holes 14 are provided at the upper and lower ends of one side of the connecting sleeve 4. The U-shaped plug plates 13 are inserted into the rectangular plug holes 14, and the size of the rectangular plug holes 14 is larger than the U-shaped plug plates 13, so that the U-shaped plug plates 13 and the connecting plates 11 are integrated to adjust the lateral pulling force of the connecting base on the connecting plates 11. A plurality of steel cable connecting seats 8 are installed on the top of the corridor 1, and the steel cable connecting seats 8 are connected to the steel cable connecting and fastening devices 7 on the casting beams 3 through the steel cables 6. The middle part of the corridor is made more stable by the inclined steel cables, so that part of the gravity in the middle part of the corridor is distributed to the casting beams 3, thereby reducing the load-bearing pressure of the connecting sleeve 4;

[0028] like Figure 4 As shown: the steel cable connection and fastening device 7 is composed of an automatic adjustment mechanism 701 and a first U-shaped connection seat 710, and a first steel cable fixing head 711 for connecting the steel cable 6 is installed in the first U-shaped connection seat 710;

[0029] like Figure 5 As shown: the steel cable connecting seat 8 is composed of a mounting seat 801 and a second U-shaped connecting seat 802, a second steel cable fixing head 803 for connecting the steel cable 6 is installed in the second U-shaped connecting seat 802, and a pressure detection device 804 is installed on the first steel cable fixing head 711 and the second steel cable fixing head 803 for detecting the traction force of the steel cable 6; the steel cable is connected by the steel cable connecting fastening device 7 and the steel cable connecting seat 8, which is convenient for installation;

[0030] like Figure 6As shown: the U-shaped plug plate 13 is connected to the automatic adjustment mechanism 701 on the casting beam 3, which is used to adjust the telescopic distance of the U-shaped plug plate 13, so that when the corridor is installed, the U-shaped plug plate 13 can be accurately aligned with the rectangular plug hole 14, and a lateral pulling force can be applied to the corridor to improve the stability of the corridor.

[0031] like Figure 4 As shown: the automatic adjustment mechanism 701 includes an adjustment box 702, two movable grooves 703 are arranged on both sides of the interior of the adjustment box 702, a reduction box 707 is installed at one end of the movable groove 703, a motor 708 is installed on one side of the reduction box 707, and a screw rod 705 is connected to the other side of the reduction box 707. The length extension direction of the screw rod 705 is parallel to the horizontal direction of the corridor 1, one end of the screw rod 705 is connected to a bearing, and a slider 704 is connected to the screw rod 705 through a thread, the screw rods 705 in the two movable grooves 703 are symmetrically distributed about the movable plate 712, the sliders 704 are welded on both sides of the movable plate 712, and a telescopic rod 706 is welded to the middle part of the movable plate 712, and one end of the telescopic rod 706 passes through one end surface of the adjustment box 702 and is fixedly connected to the first U-shaped connecting seat 710.

[0032] The motor 708 works to drive the gears in the reduction box 707 to rotate, thereby driving the screw rod 705 to rotate in the bearing, allowing the slider 704 on the screw rod 705 to move in the movable groove 703, thereby driving the telescopic rod 706 on the movable plate 712 to move, and the telescopic rod 706 is retracted by the reverse rotation of the motor, and the telescopic rod 706 is extended by the forward rotation of the motor. The extension and retraction of the telescopic rod 706 is used to adjust the tension of the steel cable and the U-shaped plug plate 13.

[0033] The regulating box 702 is installed on the casting beam 3 through the mounting plates 709 welded at both ends. The casting beam 3 and the connecting sleeve 4 are provided with through holes for the telescopic rod 706 to pass through the casting beam 3, so that the telescopic rod 706 can extend and retract through the casting beam 3. The first U-shaped connecting seat 710 and the U-shaped plug plate 13 are both welded to one end of the telescopic rod 706 to improve firmness.

[0034] The second steel cable fixing head 803 is pivotally connected to the second U-shaped connecting seat 802 through a connecting shaft and a bearing. The second U-shaped connecting seat 802 is welded to the mounting seat 801. The mounting seat 801 is welded to the keel at the top of the corridor 1, so that the mounting seat 801 is integrated with the main structure of the corridor to improve stability.

[0035] like Figure 4-6As shown: the first steel cable fixing head 711 is pivotally connected to the first U-shaped connecting seat 710 through a connecting shaft and a bearing, the steel cable 6 passes through the first steel cable fixing head 711 and the second steel cable fixing head 803 and is fixedly connected to the steel cable connecting plate 806, and a pressure detection device 804 is installed at the contact position between the steel cable connecting plate and the first steel cable fixing head 711 and the second steel cable fixing head 803, and a pressure detection device 804 is also installed on the inner side of the U-shaped plug plate 13. The pressure detection device 804 is a pressure sensor, which is electrically connected to the alarm and the motor 708 through the controller, and uses the pressure sensor to detect the tension of the steel cable and the U-shaped plug plate 1 3. The tension of the corridor is specifically as follows: when the steel cable 6 is tightened, the tension of the steel cable 6 on the steel cable connecting plate 806 causes the steel cable connecting plate 806 to generate pressure on the pressure detection device 804, and the electrical signal transmitted to the controller by the pressure detection device 804 is used to detect the tension of the steel cable; when the motor 708 rotates in the reverse direction, the telescopic rod 706 connected to the U-shaped plug plate 13 is driven to be retracted into the inside of the adjustment box 702, thereby driving the pressure detection device 804 on the U-shaped plug plate 13 to generate pressure on the inner wall of the rectangular plug hole 14, and the electrical signal transmitted to the controller by the pressure detection device 804 is used to detect the tension of the U-shaped plug plate 13.

[0036] like Figure 3 As shown: the connecting sleeve 4 is made of welded steel plates, the connecting sleeve 4 is welded to the steel section 5 through a number of connecting frames 9, the connecting sleeve 4 is also fixed to the casting beam 3 by bolts, and the steel section 5 is fixed to the casting beam 3 by bolts, thereby improving the firmness of the connection between the connecting sleeve 4 and the connecting base.

[0037] The connecting sleeve 4 is U-shaped, and is provided with a first connecting hole 10 . The connecting plate 11 is provided with a second connecting hole 12 matching the first connecting hole 10 . The connecting plate 11 is connected to the connecting sleeve 4 by plugging.

[0038] The U-shaped plug plate 13 is plugged and connected with the rectangular plug hole 14 to achieve accurate positioning of the corridor installation.

[0039] A high-stability corridor structure, the specific steps of installation are as follows:

[0040] The first step: lift the corridor 1 to a height higher than the connecting sleeve 4 by a crane or a gantry, and then slowly lower the corridor 1 by a crane, so that the connecting plates 11 at both ends of the corridor 1 are inserted into the connecting sleeve 4. During the insertion, the U-shaped plug plate 13 at the top of the connecting sleeve 4 is retracted into the adjustment box 702, and the U-shaped plug plate 13 at the bottom of the connecting sleeve 4 is extended to a set distance. When the rectangular plug hole 14 at the bottom of the connecting plate 11 drops to the upper end of the U-shaped plug plate 13 at the bottom of the connecting sleeve 4, the U-shaped plug plate 13 at the top of the connecting sleeve 4 is extended to a set distance, so that the U-shaped plug plate 13 at the top of the connecting sleeve 4 is aligned with the rectangular plug hole 14 at the top of the connecting plate 11, and then the connecting plate 11 is slowly lowered, so that the rectangular plug hole 14 is inserted on the U-shaped plug plate 13, and then the pressure detection device 804 on the inner side of the U-shaped plug plate 13 is tightly fitted with the inner wall of the rectangular plug hole 14 by contracting the U-shaped plug plate 13;

[0041] Step 2: Connect the steel cable 6 connected to the steel cable connection and fastening device 7 to the steel cable connection seat 8 at the top of the corridor 1, and then use multiple bolts to fix the connecting sleeve 4 and the connecting plate 11 together;

[0042] The third step, after the installation is completed, the telescopic rod 706 is moved by the steel cable connection fastening device 7, so that the telescopic rod 706 drives the first U-shaped connecting seat 710 to move, and the first U-shaped connecting seat 710 is moved to tighten the steel cable 6. The value of the pulling force can be intuitively seen through the pressure detection device 804, and it is set as a safe value and recorded in the system. At the same time, the automatic adjustment mechanism 701 is used to drive the U-shaped plug plate 13 to move, so that the pressure detection device 804 on the inner side of the U-shaped plug plate 13 squeezes the inner wall of the rectangular plug hole 14. The pressure detection device 804 can detect the squeezing force and record it in the system. The pressure detection device 804 is used for real-time detection. When the detection value is less than the set value, the controller controls the motor 708 to work, thereby realizing automatic reinforcement of the corridor 1 and improving safety performance.

[0043] The above embodiments only express the implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
