Technical Field

[0001] This utility model belongs to the field of steel structure installation technology, specifically relating to a connection node between a concrete corbel and a truss. Background Technology

[0002] With the development of the national economy and the improvement of people's living standards, the daily generation of garbage is increasingly becoming a social problem that pollutes the environment and hinders people's production and daily life. In order to achieve the goal of harmless, reduced, and resource-based treatment of domestic waste, building environmentally friendly waste incineration systems is becoming the primary choice for people.

[0003] Due to the vigorous advancement of urbanization in my country and the increasing scarcity of land and other natural resources, waste-to-energy incineration is the primary method for urban waste disposal. Consequently, the scale and number of waste-to-energy plants in my country have gradually expanded.

[0004] In the construction of municipal solid waste power plants, the corbels are made of concrete while the trusses are made of steel, representing two different materials. How to securely attach the trusses to the concrete corbels is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this utility model is to solve the above-mentioned technical problems existing in the prior art and to provide a connection node between a concrete corbel and a truss, which can realize a firm connection between the truss and the concrete corbel.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A concrete corbel and truss connection node includes a concrete corbel and a truss, characterized in that: it further includes a connection structure, the connection structure including a base, a horizontal plate and a support plate, several support plates are vertically fixed on the horizontal plate, an upright plate is fixed between two adjacent support plates, the upright plate is fixed on the horizontal plate, the horizontal plate is fixed on the base, the base is fixed on the concrete corbel, the support plate is provided with a slot, the lower chord of the truss is embedded in the slot and welded to the support plate.

[0008] Furthermore, the concrete corbel is equipped with bolts that pass through the base and the cross plate, and the bolts are threaded with nuts to fix the base and the cross plate to the concrete corbel.

[0009] Furthermore, the cross plate is equipped with a pad, the bolt passes through the pad, and the nut is locked on the top surface of the pad to prevent the nut from directly contacting the cross plate and causing damage to the cross plate structure.

[0010] Furthermore, a reinforcing plate is welded between the support plate and the upright plate. The reinforcing plate is welded to the horizontal plate to increase the connection strength between the support plate and the upright plate, improve the load-bearing capacity of the support plate, and enable the support plate to meet the requirements of truss installation.

[0011] Furthermore, the reinforcing plates are made of angle steel, which is readily available.

[0012] Furthermore, fixing plates are welded to both sides of the middle support plate. The fixing plate has a slot one, and the upright plate is embedded in the slot one. The fixing plate and the upright plate are welded and fixed. The fixing plate has a groove, and the groove surface one and the groove surface two of the slot are flush. The lower chord is embedded in the groove and fixedly connected to the fixing plate. This can increase the connection strength between the middle support plate and the upright plate, and at the same time increase the support area of ​​the middle support plate and the lower chord, thereby improving the truss's stability in the connection structure.

[0013] Furthermore, the support plates are provided with through holes, and steel pipes are welded into the through holes, so that all the support plates are connected into an integral structure, which improves the strength of the entire connection structure, makes the connection structure less prone to deformation, and makes the connection structure meet the installation requirements of the truss.

[0014] Furthermore, a reinforcing plate is fixed to the support plate, and the reinforcing plate is fixedly connected to the steel pipe to increase the strength of the steel pipe.

[0015] Furthermore, the fixing plate has a second groove, and the reinforcing plate is embedded in the second groove. The fixing plate and the reinforcing plate are welded and fixed, so that the fixing plate, the reinforcing plate and the steel pipe are connected as an integral structure, which further improves the strength of the connection structure.

[0016] Furthermore, a stiffening plate is welded between the fixed plate and the support plate to improve the connection strength between the fixed plate and the support plate and prevent deformation of the fixed plate.

[0017] This utility model, by adopting the above-mentioned technical solution, has the following beneficial effects:

[0018] This invention first cuts slots into the support plates, the dimensions of which are determined according to the dimensions of the lower chord of the truss. Then, a vertical plate is fixed between two adjacent support plates. Next, the integral structure formed by the support plates and vertical plates is fixed onto a horizontal plate, which is then fixed to a base to form a connecting structure. This connecting structure is then hoisted onto a concrete corbel, and the base is fixed to the concrete corbel, thus securing the connecting structure to the concrete corbel. A crane is then used to hoist the entire truss, embedding the lower chord of the truss into the slots in the support plates. Finally, the lower chord of the truss and the support plates are welded together, fixing the truss to the connecting structure. This achieves the installation of the truss on the concrete corbel, solving the technical problem of how to securely attach the truss to the concrete corbel. Attached Figure Description

[0033] like Figures 1 to 4 The image shown is an embodiment of this utility model.

[0034] This utility model includes a connecting structure c, which is installed between the concrete corbel b and the truss a, and the connecting structure c is a steel structure.

[0035] The connecting structure c includes a base 1, a horizontal plate 2, and a support plate 3. Three support plates 3 are vertically welded to the horizontal plate 2. Each support plate 3 has a slot 5, the size of which is determined according to the size of the lower chord a1 of the truss a. Adjacent support plates 3 are arranged in parallel, and a vertical plate 4 is welded between the two support plates 3. The vertical plate 4 is welded to the horizontal plate 2, and the horizontal plate 2 is welded to the base 1.

[0036] The concrete corbel b has a pre-embedded bolt 6, and the cross plate 2 has a pad 9. The bolt 6 passes through the base 1, the cross plate 2, and the pad 9. The bolt 6 is threaded with a nut 7, which is locked onto the top surface of the pad 9. This fixes the base 1 and the cross plate 2 to the concrete corbel b. The pad 9 also prevents the nut 7 from directly contacting the cross plate 2 and causing structural damage to the cross plate 2.

[0037] The lower chord a1 of truss a is embedded in the slot 5, and the lower chord a1 is welded and fixed to the support plate 3. A reinforcing plate 8 is welded between the support plate 3 and the vertical plate 4. The reinforcing plate 8 is made of angle steel, which is readily available. The reinforcing plate 8 is welded to the horizontal plate 2 to increase the connection strength between the support plate 3 and the vertical plate 4, improve the load-bearing capacity of the support plate 3, and enable the support plate 3 to meet the installation requirements of truss a.

[0038] like Figures 5 to 10 The image shown is a second embodiment of this utility model.

[0039] Based on the structure of Embodiment 1, this utility model designs another embodiment to strengthen the overall structure so that the connecting structure c can support the entire truss a.

[0040] Specifically, in this invention, fixing plates 10 are welded to both sides of the support plate 3 in the middle, and stiffening plates 13 are welded between the fixing plates 10 and the support plate 3 to improve the connection strength between the fixing plates 10 and the support plate 3 and prevent deformation of the fixing plates 10. The fixing plates 10 are provided with a groove 17, and the upright plates 4 are embedded in the groove 17. The fixing plates 10 and the upright plates 4 are welded and fixed.

[0041] The fixing plate 10 is provided with a groove 14. The groove surface 1 of the groove 14 is flush with the groove surface 2 of the slot 5. The lower chord a1 is embedded in the groove 14 and welded to the fixing plate 10. This can increase the connection strength between the middle support plate 3 and the upright plate 4, and at the same time increase the support area of ​​the middle support plate 3 and the lower chord a1, thereby improving the firmness of the truss a on the connection structure c.

[0042] Each of the three support plates 3 has a through hole 16, and a steel pipe 11 is welded into the through hole 16, so that the three support plates 3 are connected into an integral structure, which improves the strength of the entire connection structure c, makes the connection structure c less prone to deformation, and makes the connection structure c meet the installation requirements of truss a.

[0043] The support plate 3 is welded with an L-shaped reinforcing plate 12, which is welded and fixed to the steel pipe 11 to increase the strength of the steel pipe 11. The fixing plate 10 is provided with a second groove 15, and the reinforcing plate 12 is embedded in the second groove 15. The fixing plate 10 and the reinforcing plate 12 are welded and fixed, so that the fixing plate 10, the reinforcing plate 12 and the steel pipe 11 are connected into an integral structure, further improving the strength of the connection structure c.

[0044] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
