[0017] The present invention is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0018] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the present invention defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the present invention.

[0019] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0020] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0021] like Figure 1 As shown, a preferred embodiment of the present invention provides a connection device for an assembled steel structure building, comprising a first steel beam block 1, a second steel beam block 2, a first connecting member, and a second connecting member 4. The first steel beam block 1 is connected to the second steel beam block through the first connecting member. The second connecting member 4 is annular and surrounds the outside of the first steel beam block 1 and the second steel beam block, and the connection between the first steel beam block 1 and the second steel beam block is circled inside. The top and bottom ends of the second connecting member 4 are respectively connected to the side walls of the first steel beam block 1 and the side walls of the second steel beam block through wing plates 16; the space between the second connecting member 4 and the first steel beam block 1 and the second steel beam block is filled with high-strength concrete.

[0022] In the above technical solution, the first connecting member and the second connecting member are simultaneously used to realize the connection between the first steel beam block and the second steel beam block, wherein the first connecting member mainly realizes the vertical connection, and the second connecting member mainly realizes the transverse connection reinforcement, and the simultaneous action of the two greatly enhances the stability of the entire structure.

[0023] In a preferred embodiment of the present invention, the first connecting member includes a connecting protrusion 3, and there are multiple connecting protrusions 3 distributed at the bottom of the first steel beam block 1 along the width direction of the first steel beam block 1. The connecting protrusion 3 is in the shape of an elongated strip, and the cross-section of the connecting protrusion 3 is a trapezoidal structure that is short on the top and long on the bottom. The upper surface of the first steel beam block 1 is recessed downward to form multiple elongated connecting grooves 5, and the connecting grooves 5 correspond to the connecting protrusions 3 one by one, and the connecting protrusions 3 can be inserted into the corresponding connecting grooves 5.

[0024] In the above technical solution, the first steel beam block and the second steel beam block can be quickly and conveniently connected by inserting the connecting protrusion 3 at the bottom of the first steel beam block 1 into the connecting groove of the second steel beam block 2. After the two are spliced, concrete is poured into the space between the annular second connecting piece and the first steel beam block and the second steel beam block, and the concrete will also penetrate into the gap between the first steel beam block and the second steel beam block, further improving the connection firmness of the entire structure.

[0025] In a preferred embodiment of the present invention, considering that the connection between the first steel beam block and the second steel beam block is prone to rust, which makes it inconvenient for the first steel beam block to move along the second steel beam block, the following arrangement is made to avoid this situation: a long strip-shaped accommodating cavity 6 is arranged at the bottom of the connecting groove 5, and the accommodating cavity 6 is distributed along the length direction of the second steel beam block 2; a cover plate 7 is arranged above the accommodating cavity 6, and the cover plate 7 is connected to the pressure plate 8 through a plurality of pressing springs 9; the cover plate 7 and the pressure plate 8 are both arranged horizontally, and the pressure plate 8 is located in the accommodating cavity 6; the space in the accommodating cavity 6 below the pressure plate 8 is filled with a sponge strip 10, and the sponge strip 10 is soaked with lubricating oil.

[0026] When the first steel beam block is pushed along the second steel beam block, the connection protrusion will move in the connection groove. During the movement, the connection protrusion will encounter the cover plate 7. The connection protrusion 3 presses down the cover plate 7, and then the pressing spring 9 is deformed, squeezing the pressure plate below. The pressure plate further squeezes the sponge soaked with lubricating oil. The lubricating oil is squeezed out and moves upward, soaking the surface of the connection groove, and lubricating the connection between the connection protrusion and the connection groove. Considering the convenience of the first steel beam block to be pushed along the second steel beam block, the cover plate is set to be inclined along the length direction of the second steel beam block. Along the moving direction, the cover plate gradually tilts upward.

[0027] When the pressing spring 9 is in a naturally extended state, the top of the cover plate 7 is higher than the top of the accommodating chamber 6 , and the accommodating chamber 6 is connected to the top of the accommodating chamber 6 through the conveying channel 11 , so that the lubricating oil can be conveyed to the top of the accommodating chamber through the conveying channel 11 .

[0028] In a preferred embodiment of the present invention, the bottom end of the side wall of the accommodating chamber 6 is connected to the bottom of the accommodating chamber 6 through a conveying channel. Compared with connecting the bottom of the accommodating chamber to the conveying channel, the bottom end of the side wall of the accommodating chamber is connected to the conveying channel, the conveying pipeline is shorter, and it does not affect the squeezing and discharge of all the lubricating oil at the bottom.

[0029] In a preferred embodiment of the present invention, it is also considered that the cover plate is conventionally a panel. After the inclined setting, the first steel beam block can only move on the second steel beam block along a fixed direction, which is very inconvenient during actual construction. In order to solve this technical problem, the structure of the cover plate is improved. Specifically, the cover plate 7 includes two sub-cover plates 7-1, one end of the two sub-cover plates 7-1 is connected by a connecting spring 14, and the other ends of the two sub-cover plates are respectively connected to universal balls 13, and a slide groove 12 is provided on the surface of the bottom of the accommodating cavity 6, and the slide groove 12 is arranged along the length direction of the second steel beam block, and the universal ball 13 is rollingly arranged in the slide groove 12.

[0030] The connecting spring 14 is connected to the pressing plate 8 via a vertically arranged limit spring 15 .

[0031] In this way, the first steel beam block can move forward or backward along the second steel beam block, and the lubricating oil on the sponge in the accommodating cavity can be squeezed out during the moving process.

[0032] In a preferred embodiment of the present invention, the wing plate 16 is triangular in shape, one right-angled side of the wing plate is connected to the outer side of the first steel beam block 1 or the second steel beam block by bolts, and the other right-angled side is connected to the second connecting member 4 by bolts.

[0033] In a preferred embodiment of the present invention, an annular sealing plate 17 is provided at the lower end of the second connecting member 4, and the sealing plate seamlessly connects the outer side of the second steel beam block and the inner wall of the second connecting member 4 to form a casting space, which is convenient for the subsequent casting of high-strength concrete and improves the overall strength of the structure.

[0034] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the present invention is not limited to the specific details and the illustrations shown and described herein.
