The embodiments described below with reference to the drawings are exemplary and are used only for explaining the utility model, and cannot be understood as limiting the utility model.

[0025] The embodiments of the utility model will be described below according to the overall structure of the utility model.

[0026] Embodiment one

[0027] A socket type welding-free fixed steel reinforcement support, such as Figures 1-9As shown, including the bottom layer of reinforcement 1, the upper layer of reinforcement 2, beam 3, lower pole assembly 4, upper pole assembly 5, diagonal brace assembly 6 and binding wire 7;

[0028] The bottom layer of reinforcement 1 and the upper layer of reinforcement 2 are both formed by crossing connection of multiple horizontal and vertical reinforcements, forming a stable grid structure, and the reinforcement uses high-strength building reinforcement, such as HRB400 grade reinforcement, which has good tensile strength and yield strength and can withstand large loads;

[0029] The bottom layer of reinforcement 1 serves as the foundation of the entire support and is laid on the concrete base to provide a stable support surface for the support, and the upper layer of reinforcement 2 is used to bear the upper structural load of the building, and the reinforcement spacing and specifications are determined according to design requirements to ensure that the structural strength requirements can be met;

[0030] At the construction site, first, the laying position of the bottom layer of reinforcement 1 is determined according to the design drawing, and the measuring tool is used for accurate line laying, and the reinforcement of the bottom layer of reinforcement 1 is placed neatly according to the designed spacing, and the reinforcement at the intersection is firmly bound with the binding wire 7 to ensure the integrity of the reinforcement grid, and for the upper layer of reinforcement 2, after the bottom layer of reinforcement 1 is laid and accepted, it is placed on the support according to the design height and position, and is also preliminarily fixed with the binding wire 7, and after the support is installed, the final adjustment and fixation are carried out;

[0031] The pole 401 can be made of round steel, and the top and bottom are provided with a top sleeve 402 and a bottom sleeve 405, respectively, and the adjusting sleeve 403 is a sleeve with a thread inside, which is screwed with the top of the pole 401, and the pad 404 is a square or circular high-strength plastic part with a threaded hole in the center, which is screwed with the bottom of the pole 401;

[0032] During installation, first, the pad 404 is placed at the predetermined position on the bottom layer of reinforcement 1, then the bottom of the pole 401 is screwed into the threaded hole of the pad 404, and is tightened to an appropriate degree, then the adjusting sleeve 403 is screwed into the top of the pole 401, and the height of the pole 401 is adjusted as needed;

[0033] The threaded connection of the adjusting sleeve 403 and the pole 401 realizes the height adjustment function, when the height of the support needs to be adjusted to adapt to the horizontal error of the base, the wrench is used to rotate the adjusting sleeve 403 to move it up or down on the pole 401;

[0034] When the adjusting sleeve 403 is rotated upward, the support rod 401 moves downward relative to the adjusting sleeve 403, the height of the support is reduced, when the adjusting sleeve 403 is rotated downward, the support rod 401 moves upward relative to the adjusting sleeve 403, the height of the support is increased, during the adjusting process, the levelness of the support is monitored in real time by using a level meter or other measuring tools, to ensure that the adjusted support is level, after the adjusting is completed, it is checked again whether the connection between the adjusting sleeve 403 and the support rod 401 is firm, to prevent loosening during subsequent construction process;

[0035] The supporting rod 501 is vertically welded on the socket sleeve 504, the socket sleeve 504 is a hollow tubular structure, used for connecting with the top of the support rod 401 of the lower support rod assembly 4 and the connecting head 602 of the inclined support rod assembly 6, the supporting plate 502 is horizontally welded on the top of the supporting rod 501, and a plurality of groups of U-shaped buckles 503 are uniformly fixed on the top of the supporting plate 502;

[0036] During assembly, first, the supporting rod 501 is firmly welded with the socket sleeve 504, to ensure that the welding quality meets the requirements, the welding seam is full, without pores, cracks and other defects, then the supporting plate 502 is welded on the top of the supporting rod 501, to ensure that the supporting plate 502 is horizontal, finally, the U-shaped buckles 503 are welded on the top of the supporting plate 502 according to the designed interval;

[0037] When the upper layer of reinforcement mesh 2 is placed on the support, the cross beam 3 is above the supporting plate 502, the U-shaped buckle 503 extends downward to the inside of the cross beam 3, by tightening the nut on the U-shaped buckle 503, the U-shaped buckle 503 tightly clamps the cross beam 3, so as to firmly fix the upper layer of reinforcement mesh 2 on the supporting plate 502, this supporting mode can uniformly disperse the load of the upper layer of reinforcement mesh 2, to ensure that the upper layer of reinforcement mesh 2 does not displace or sink during the construction process, at the same time, due to the adjustability of the U-shaped buckle 503, different sizes of cross beams 3 can be adapted, to improve the universality of the support;

[0038] The inclined rod 601 is made of angle steel, having certain bending resistance and pressure resistance, the connecting head 602 is welded on the top of the inclined rod 601, the connecting head 602 is internally provided with a matching thread hole matched with the bolt hole 505 of the socket sleeve 504, the connecting head 602 is fixedly connected with the socket sleeve 504 through a bolt, the supporting leg 603 is welded on the bottom of the inclined rod 601, the supporting leg 603 is a circular pipe with a circular section, one end of which is welded with the bottom of the inclined rod 601, and the other end is provided with a small hole used for connecting with the bottom layer of reinforcement mesh 1, during the manufacturing of the inclined support rod assembly 6, the welding quality is ensured, especially the welding between the connecting head 602 and the inclined rod 601 and between the supporting leg 603 and the inclined rod 601, which needs to be strictly checked;

[0039] The inclined bracing rod assembly 6 is connected with the upper supporting rod assembly 5 through the connecting head 602 and the socket 504, and is connected with the bottom layer of the reinforcement mesh 1 through the supporting leg 603, forming a triangular stable structure. When the support is subjected to lateral force such as wind force, construction load eccentricity and the like, the inclined bracing rod assembly 6 can transmit the lateral force to the bottom layer of the reinforcement mesh 1 and the upper supporting rod assembly 5, thereby enhancing the lateral stability of the whole support. The plurality of inclined bracing rod assemblies 6 are evenly distributed around the support and jointly act, effectively preventing the support from overturning or deforming, ensuring that the support can bear various loads during the construction process and ensuring the construction quality of the foundation component;

[0040] The binding wire 7 plays an important connecting role in the assembly process of the steel reinforcement support. In the manufacturing process of the bottom layer of the reinforcement mesh 1 and the upper layer of the reinforcement mesh 2, the binding wire 7 is used to firmly bind the intersection of the horizontal reinforcement and the vertical reinforcement, ensuring the integrity of the reinforcement mesh;

[0041] In the connection between the inclined bracing rod assembly 6 and the bottom layer of the reinforcement mesh 1, the binding wire 7 passes through the small hole on the supporting leg 603, tightly binding the supporting leg 603 on the reinforcement of the bottom layer of the reinforcement mesh 1, preventing the inclined bracing rod assembly 6 from loosening or displacing. After the whole support is assembled, the binding wire 7 can be used to additionally reinforce some key parts, such as the connection between the upper layer of the reinforcement mesh 2 and the cross beam 3, further enhancing the reliability of the connection;

[0042] The binding wire 7 is selected from galvanized iron wires with appropriate specifications, such as galvanized iron wires with a diameter of 0.7-1.2 mm. In the binding process, different binding methods are adopted according to different connection parts and requirements. For the binding of the reinforcement mesh, the cross binding method is generally adopted, that is, the binding wire 7 is wound around the reinforcement twice at the intersection and then is tightened. The tightening degree should be moderate, that is, it should be firm enough to ensure the connection, but not too tight to cause deformation of the reinforcement;

[0043] For the binding between the inclined bracing rod assembly 6 and the bottom layer of the reinforcement mesh 1, the binding wire 7 is passed through the small hole of the supporting leg 603, wound around the reinforcement of the bottom layer of the reinforcement mesh 1 for several turns, and then is tightened, so that the supporting leg 603 is tightly attached to the bottom layer of the reinforcement mesh 1. During the binding process, the binding quality should be checked to ensure that each binding point is firm and reliable;
