DETAILED DESCRIPTION

[0024] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0025] Example

[0026] A building steel structure connector described in this embodiment, such as Figures 1 to 5 As shown, it includes an angle code, which includes a first connecting plate 1, and the first connecting plate 1 includes a first horizontal support plate 1.1. A first vertical support plate 1.2 vertically arranged therewith is fixed on the rear side wall of the first horizontal support plate 1.1; the first horizontal support plate 1.1 and the first vertical support plate 1.2 are integrally formed.

[0027] The inner corner of the first connecting plate 1 is provided with a second connecting plate 2 overlapping with the inner corner, and the second connecting plate 2 includes a second horizontal support plate 2.1, and a second vertical support plate 2.2 arranged perpendicularly thereto is fixed on the rear side wall of the second horizontal support plate 2.1; the second horizontal support plate 2.1 and the second vertical support plate 2.2 are integrally formed. The inner corner of the first connecting plate 1 is also called the inner corner, which is the inner corner of the first connecting plate 1. In addition, there is a positive angle, which is also called the outer angle, which is located at the outer corner of the first connecting plate 1.

[0028] like Figure 4 As shown, the first horizontal support plate 1.1 is provided with a plurality of first through holes which are connected up and down, and a first guide groove which is connected to the first through hole and the right side wall of the first horizontal support plate 1.1 is provided; there are two first through holes on the first horizontal support plate 1.1 and they are distributed front to back; the first guide groove is connected to the right side wall of the first horizontal support plate 1.1, and the screw can enter the first through hole from the first guide groove.

[0029] The first vertical support plate 1.2 is provided with a plurality of second through holes connected front to back, and a second guide groove connected to the second through hole and the right side wall of the first vertical support plate 1.2 is provided; there are two second through holes on the first vertical support plate 1.2 and they are distributed up and down; the second guide groove is connected to the right side wall of the first vertical support plate 1.2, and the screw can enter the second through hole from the second guide groove; if the first guide groove and the second guide groove are in the same plane, the two should be in a parallel state with each other.

[0030] Corresponding to each first through hole, a third through hole connected up and down is opened on the second horizontal support plate 2.1, and a third guide groove connected to the left side wall of the second horizontal support plate 2.1 is opened; the third guide groove and the first guide groove are arranged in an interlaced manner, and the intersection of the two is the first through hole and the third through hole.

[0031] Corresponding to each second through hole, a fourth through hole communicating front to back is opened on the second vertical support plate 2.2, and a fourth guide groove communicating with the left side wall of the second vertical support plate 2.2 is opened; the part where the fourth guide groove intersects with the second guide groove is the second through hole and the fourth through hole.

[0032] The second horizontal support plate 2.1 is attached to the top of the first horizontal support plate 1.1, and the second vertical support plate 2.2 is attached to the front side wall of the first vertical support plate 1.2.

[0033] like Figure 3 and Figure 4 As shown, two positioning protrusions 3 distributed on the left and right are fixed on the top of the first horizontal support plate 1.1 and the front side wall of the first vertical support plate 1.2, and a positioning groove is opened on the bottom of the second horizontal support plate 2.1 and the rear side wall of the second vertical support plate 2.2 corresponding to each positioning protrusion 3; the positioning protrusion 3 is integrally arranged with the first horizontal support plate 1.1 and the first vertical support plate 1.2; when in use, the positioning protrusion 3 cooperates with the positioning groove not only to make the first connecting plate 1 and the second connecting plate 2 overlap better, but also to prevent the first connecting plate 1 and the second connecting plate 2 from loosening to a certain extent. At the same time, the positioning protrusion 3 can also increase the structural strength of the first connecting plate 1.

[0034] In actual use: pre-set the screws at the connection of the steel beam, do not fully nail them in, then insert the first connecting plate 1 from the left side of the screw, and the second connecting plate 2 from the right side of the screw. When inserting, the notch of the first guide groove and the notch of the third guide groove are aligned with the same screw a, and the notch of the second guide groove and the notch of the fourth guide groove are aligned with the same screw b. The first connecting plate 1 is inserted from left to right, and the screw a enters the first through hole from the first guide groove, and the screw b enters the second through hole from the second guide groove. The second connecting plate 2 is inserted from right to left, and the screw a enters the third through hole from the third guide groove, and the screw b enters the fourth through hole from the fourth guide groove. The groove enters into the fourth through hole. At this time, the first connecting plate 1 and the second connecting plate 2 overlap, the first through hole and the third through hole overlap, and the second through hole and the fourth through hole overlap. Finally, screws a and screws b are completely tightened to lock the first connecting plate 1 and the second connecting plate 2 together. At the same time, the two restrain each other to prevent the two sides from detaching from one side of the screw; the first connecting plate 1 and the second connecting plate 2 overlap each other to ensure the structural strength to a certain extent; in this way, there is no need to hold the angle code by hand for special positioning during the installation process, which reduces the difficulty of installing the angle code, makes the installation more convenient, and can reduce the fatigue of workers to a certain extent.

[0035] In addition, considering that the front and rear positions of the screws inserted into the first connecting plate 1 and the second connecting plate 2 are different, if the second horizontal support plate 2.1 and the second vertical support plate 2.2 are in a horizontal state, the spacing between the third guide groove and the fourth guide groove is smaller than the spacing between the first guide groove and the second guide groove. Because the second connecting plate 2 is located in front of the first connecting plate 1, and because the extension lines of screw a and screw b will cross, the spacing between screw a and screw b will become smaller and smaller. When the second connecting plate 2 is located in the front, the spacing between the third guide groove and the fourth guide groove is smaller than the spacing between the first guide groove and the second guide groove. In addition, since screws a and screws b will produce a certain radial movement along the third through hole and the fourth through hole in the process of the second connecting plate 2 approaching the first connecting plate 1, the third through hole and the fourth through hole need to be set as long slots to ensure that the second connecting plate 2 can move along the length direction of screws a and screws b.
