[0002] Steel structure is a commonly used building form in modern buildings. It is widely used in the modern construction industry because of its convenient manufacturing and short construction period, as well as its high structural strength. In the current steel structure construction, the support foundation of the steel structure is mainly built by welding or riveting. Some connection nodes in the steel structure will adopt a cross connection method. At present, the cross-cross steel frame connection mainly adopts the overlap method combined with riveting and welding to limit the position of the cross connection. However, welding is used more frequently in this cross connection method, and the operation is very cumbersome. If riveting is used, a large number of rivets are required, otherwise the corresponding fixing effect cannot be achieved. In view of this, in-depth research on the above-mentioned problems has led to the emergence of this case. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-4 The utility model provides an implementation scheme: in modern steel structure buildings, the cross connection of steel structures is mainly connected by riveting or welding. Both connection methods have the problem of cumbersome operation. Therefore, the present application designs a steel structure foundation cross steel frame connection structure. When connected, the cross connection is divided into a vertical steel frame 1 and a horizontal steel frame 2. The vertical steel frame 1 and the horizontal steel frame 2 are vertically connected. The horizontal steel frame 2 and the vertical steel frame 1 are both rectangular steel brackets. In order to reduce weight, the steel bracket can be slotted or hollowed. A rectangular connection groove 3 is opened in the middle section of the vertical steel frame. The horizontal steel frame 2 and the vertical steel frame 1 are correspondingly provided with an insertion groove 4. The insertion groove 4 is inserted in the connection groove 3. The insertion groove 4 wraps the two sides of the vertical steel frame 1, and the connection groove 3 wraps the two sides of the horizontal steel frame 2, so that the horizontal steel frame 2 and the vertical steel frame 1 limit each other.
[0021] According to the instruction manual Figure 1-3 It can be seen that a pair of X-shaped slots 5 are respectively provided at the back of the insertion slot 4 and the connecting slot 3, a pair of X-shaped limit plates 6 are embedded in the pair of X-shaped slots 5, and two pairs of connecting holes 7 are respectively provided at the four corners of the pair of X-shaped limit plates 6. The thickness of the pair of X-shaped limit plates 6 is greater than the depth of the pair of X-shaped slots 5. The pair of X-shaped limit plates 6 are pulled and squeezed by two pairs of tension bolts 8 arranged on both sides of the pair of X-shaped limit plates 6, so as to achieve the tension effect on the back of the insertion slot 4 and the connecting slot 3 in the horizontal direction, and then the horizontal steel frame 2 and the vertical steel frame 1 are horizontally limited and connected. At the same time, due to the existence of the X-shaped limit plates 6, the tension bolts 8 are not directly fixed on the horizontal steel frame 2 and the vertical steel frame 1, thereby increasing the tension force area of the tension bolts 8 and avoiding deformation problems such as depression.
[0022] According to the instruction manual Figure 1-3 It can be seen that, further, the insertion slot 4 is wrapped around the outside of the connecting slot 3, and two pairs of clamping plates 9 are arranged on both sides of the connecting slot 3. The two pairs of clamping plates 9 are arranged on both sides of the transverse steel frame 2. The two pairs of clamping plates 9 are used to improve the longitudinal support of the transverse steel frame 2 and avoid tilting of the two sides of the transverse steel frame 2.
[0023] As a preferred solution, further, the width of the insertion slot 4 matches the width of the vertical steel frame 1 , and the width of the connection slot 3 matches the width of the horizontal steel frame 2 .
[0024] As a preferred solution, further, the depth of the insertion groove 4 and the depth of the connection groove 3 are respectively half of the width of the horizontal steel frame 2 and the vertical steel frame 1, so that after the horizontal steel frame 2 and the vertical steel frame 1 are connected, the surfaces of the two are kept flush.
[0025] As a preferred solution, further, at least two pairs of limiting holes are correspondingly provided on the two pairs of clamping plates 9, and the limiting holes on the pair of clamping plates 9 on the same side are connected to the transverse steel frame 2 through rivets 10, so as to strengthen the connection and maintain balance.
[0026] As a preferred solution, further, a pair of center docking holes are set in the center of the pair of X-shaped limit plates 6, and the pair of center docking holes are connected by a back-pull screw 11 to further limit the pair of X-shaped limit plates 6.
[0027] As a preferred solution, further, two pairs of reinforcing blocks 12 are respectively provided on the two pairs of clamping plates 9 , and the reinforcing blocks 12 with a triangular structure are used to improve the supporting force effect of the clamping plates 9 .
[0028] From the above, it can be generally known that the cross-cross steel frame connection structure of the steel structure foundation is used for the cross-cross connection position of the steel structure. The socket structure design is used to plug the middle section of the horizontal steel frame 2 and the vertical steel frame 1, and the X-shaped limiting plate 6 is used to pull the connection position, which not only ensures the horizontal balance but also reduces the position of the connection point. The limiting effect of the clamping plate 9 is used to support and limit the horizontal steel frame 2 in the horizontal direction, thereby further improving the stability of the connection position.
[0029] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
