[0018] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0019] Reference Figure 1-2 As shown,

[0020] A connection structure between a steel structure beam and a curtain wall 3 keel 2,

[0021] It includes a steel beam 1, a keel 2 installed on the steel beam 1, and a curtain wall 3 installed on the keel 2;

[0022] The steel beam 1 is provided with a connecting steel plate 11, and the keel 2 includes a first assembly 21 for fixedly connecting with the connecting steel plate 11, a second assembly 22 detachably connected with the first assembly 21, and a third assembly 23 detachably connected with the second assembly 22, and the third assembly 23 is used for installing the curtain wall 3;

[0023] The second assembly 22 includes a bolt 221 installed on the first assembly 21 and a detachable steel 222 installed in cooperation with the bolt 221; the detachable steel 222 is provided with an I-shaped groove 2221 penetrating along the length direction at one end corresponding to the bolt 221, the I-shaped groove 2221 is adapted to the head of the bolt 221, and is plug-connected with the head of the bolt 221 by plugging, and the bolt 221 is fixedly connected with the first assembly 21 by a nut;

[0024] The detachable steel section 222 is provided with a clamping piece 2222 at one end corresponding to the third assembly 23, and the third assembly 23 is provided with a clamping groove 231 penetrating along the length direction at the position corresponding to the clamping piece 2222. The clamping groove 231 of the third assembly 23 cooperates with the clamping piece 2222 to be connected by insertion.

[0025] The steel beam 1 is a steel structure beam, wherein the first assembly 21 and the steel beam 1 can be fixedly connected, and the specific connection method can be fixed connection with bolts 221 or welding.

[0026] The I-slot 2221 on the detachable steel section 222 can be plugged in with the head of the bolt 221, and can be installed conveniently and quickly. In the installation process, a number of bolts 221 are pre-installed on the first assembly 21, but the bolts 221 are not tightened. Then the I-slot 2221 on the detachable steel section 222 is plugged in with the bolt 221, and the head of the bolt 221 is aligned with the opening at the end of the I-slot 2221, and inserted so that the head of the bolt 221 slides in the I-slot 2221 until it is installed in place, and then the nut is tightened to fasten the detachable steel section 222 to the first assembly 21.

[0027] The clamping piece 2222 on the detachable steel section 222 can also be plugged in with the clamping groove 231, so that the end opening of the clamping groove 231 is aligned with the clamping piece 2222, and plugged in, so as to achieve plugging while limiting lateral disengagement, thereby completing the installation.

[0028] The above structure can make the installation of the keel 2 structure more convenient, make the installation structure of the curtain wall 3 simpler, and improve the installation efficiency.

[0029] In order to make the installation more stable and to adjust the position of the curtain wall 3 , a buffer pad 4 is provided between the detachable steel section 222 and the first assembly 21 .

[0030] The provision of the buffer pad 4 can make the installation more stable and reduce the impact of vibrations, such as vibrations caused by strong winds or vibrations caused by trucks passing by on the road. In addition, the position of the detachable steel section 222 can be adjusted according to the thickness of the buffer pad 4, so that the position of the curtain wall 3 can be fine-tuned to achieve a better flatness of the overall curtain wall 3.

[0031] In a further configuration, a plurality of serrated grooves 5 are provided at positions corresponding to the nuts on the first assembly 21, and a pad 6 is provided between the nut and the serrated groove 5. The positions corresponding to the serrated grooves 5 on the pad 6 are adapted to the serrated grooves 5 to form an interlocking structure; the pad 6 is pressed onto the first assembly 21 by the cooperation of the nut and the bolt 221.

[0032] By using the cooperation between the sawtooth groove 5 and the pad 6, the pad 6 can be kept in a stable state and will not loosen, and the bite state can make the fixation more stable. In fact, based on the bite cooperation between the pad 6 and the sawtooth groove 5, the through hole on the first assembly 21 for passing the bolt 221 can be long strip, and the pad 6 is a round hole. At this time, the position movement of the pad 6 and the sawtooth groove 5 can be used for cooperation, so that the bolt 221 has the adjustment function of moving along the through hole. Since the pad 6 is a round hole, the bolt 221 and the nut can still be stably installed, and the bite of the pad 6 can be used to limit the movement. It should be noted that the strip direction of the sawtooth is more perpendicular to the long strip direction of the through hole, and the limiting effect of the sawtooth can be used to limit the tendency of moving along the strip direction of the through hole.

[0033] In a more specific solution, the cross-section of the clamping piece 2222 on the detachable steel section 222 is spherical, and the shape of the clamping groove 231 is adapted to the clamping piece 2222 .

[0034] The cross-section of the clamping member 2222 is spherical, which can provide a certain lateral rotation range, provide a lateral fine-tuning function for the third assembly 23, and can achieve a stable clamping state to prevent the third assembly 23 from falling off the detachable steel section 222.

[0035] It is well known to those skilled in the art that the spherical structure needs to reserve a certain amount of space for rotation when realizing lateral rotation, so as to avoid the failure of lateral fine-tuning due to obstruction and influence on rotation. As shown in the figure, a certain amount of space can be left between the spherical part and the detachable steel 222.

[0036] In addition, in further optimization, a slot 211 for inserting the connecting steel plate 11 is provided at a position corresponding to the connecting steel plate 11 on the first assembly 21, and a plurality of serrated grooves 5 are provided on the outer walls on both sides of the slot 211 of the first assembly 21. The first assembly 21 is fixedly connected to the connecting steel plate 11 by a bolt 221. The bolt 221 penetrates through the slot 211 of the first assembly 21 and the connecting steel plate 11 and is fixedly connected by a nut. A gasket 6 is provided between the head of the bolt 221 and the nut and the first assembly 21. The position of the gasket 6 corresponding to the serrated groove 5 is adapted to the serrated groove 5 to form an interlocking structure.

[0037] Similarly, the cooperation between the serrated groove 5 and the pad 6 can make the installation more stable, and can also cooperate with the strip-shaped through hole to adjust the position of the bolt 221, which has a certain fine-tuning effect. Moreover, the fixation in this solution requires two pads 6 to cooperate, both of which are adapted to the serrated groove 5, which can make the effect more stable.

[0038] Furthermore, a buffer pad 4 is provided between the connecting steel plate 11 and the inner wall of the slot 211 .

[0039] The buffer pad 4 can provide a buffering effect between the steel plate and the inner wall of the slot 211, and can also reduce the impact of vibration, and can also improve the sealing and installation stability.

[0040] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
