Description

Technical Field

[0001] This invention relates to the field of building steel structure technology, specifically a truss-type steel support structure suitable for large-span hollow floor slabs. Background Technology

[0002] Truss-type steel bracing structures are truss systems made of steel, mainly used in construction, bridges, and foundation pit support projects. They are characterized by large spans, high load-bearing capacity, and convenient construction. Truss-type steel bracing structures generally rely on axial forces (tension or compression) in the members, and the joints are usually hinged or rigid. They are mainly used in large-span floor slabs and large buildings such as convention centers.

[0003] Large-span hollow core slabs are a modern construction technology that creates a hollow structure by embedding internal molds within cast-in-place concrete slabs. They offer advantages such as lightweight construction, high rigidity, and multi-functionality. During construction, a truss-type steel support structure must be erected on the outer side to ensure safety and stability.

[0004] However, this truss-type steel support structure has the following drawbacks in practical use: 1. When constructing existing large-span hollow core slabs, a truss-type steel support structure needs to be erected on the outside of the slab to ensure safety during construction. Traditional truss-type steel support structures require screws and other installation accessories to be screwed into the joints connecting to other structures to improve the stability and firmness of the installation. However, in traditional joint structures, the fixing joints are generally screwed into the left and right sides of the steel support frame. These joints have weak fixing capacity for the included angle portion on the outside of the steel support frame. The steel support frame at the bottom, subjected to significant compressive force, is prone to bending or even breakage due to insufficient joint concentration, resulting in weak support strength of the truss-type steel support structure. 2. When using existing truss-type steel support structures to protect and support large-span hollow floor slabs during internal construction, it is necessary to install diagonal support beam structures inside the truss-type steel support structure to improve the strength of the connection between the upper and lower supports. Traditional diagonal support beam structures generally achieve support through staggered diagonal beams, which have relatively weak supporting capacity and are prone to bending or even breakage when the top support or beam structure is subjected to frontal impact. Summary of the Invention

[0005] The purpose of this invention is to provide a truss-type steel support structure suitable for large-span hollow floor slabs, so as to solve the problems mentioned in the background art.

Multiple vertical steel bars located on the left and right sides of the center are provided on the left and right sides of the side assembly assembly. First hook-shaped bodies are provided on the left and right sides of the horizontal steel bars, and vertical steel bars are pressed and fixed inside the first hook-shaped bodies.

[0007] As a preferred embodiment of the present invention, the building foundation includes: a pre-embedded foundation disposed within the pre-embedded area of ​​the building; a vertical steel frame fixed to the top of the pre-embedded foundation; and a pre-reserved vertical groove formed at the center of the outer side of the vertical steel frame. The central part of the vertical steel frame is designed in a cross shape.

[0008] As a preferred embodiment of the present invention, the exterior of the vertical steel frame is provided with a protrusion that is welded integrally with the internal cross-shaped structure perpendicularly to it, and the outer surface of the protrusion is provided with the reserved vertical groove. Side assembly components are installed on the outer side and at the included angles of the vertical steel frame.

[0009] As a preferred embodiment of the present invention, the longitudinal support structure includes: an I-beam longitudinal steel bracket fixed to the side of the side assembly assembly by screws; side metal seats fixed to both sides of the bottom by screws; a metal diagonal support arm installed on the outside of the side metal seat; and a central circular protrusion welded and fixed to the metal diagonal support arm and disposed between the two I-beam longitudinal steel brackets. The metal diagonal support arm welded to the outer side of the central convex shape is provided in multiple forms.

[0010] In a preferred embodiment of the present invention, the central portions of the upper and lower sides of the I-beam longitudinal steel bracket are fixed with intermediate metal seats by screws, and the left and right sides of the intermediate metal seats are movably connected with inclined support metal arms. The bottom ends of the inclined support metal arms are movably installed between two adjacent inclined metal support arms. The upper and lower sides of the I-beam longitudinal steel support are provided with reinforcing steel bars located on the side of the middle metal seat. The reinforcing steel bars are installed and fixed on the side of the vertical steel frame, and there are multiple reinforcing steel bars.

[0011] As a preferred embodiment of the present invention, the side assembly includes: a conical metal base fixed to the outside of the vertical steel frame by screws; a cross-shaped assembly plate welded to the center of the inside of the conical metal base; and an alignment metal protrusion disposed at the center of the side of the conical metal base and extending into the reserved vertical groove. The tapered metal base has an I-beam longitudinal steel bracket fixed to the side away from the aligning metal protrusion by screws. Angle positioning components are fixed to the left and right sides of the tapered metal base by screws. A set of vertical steel bars is installed through the center of the tapered metal base. Multiple vertical steel bars are provided on the left and right sides of the tapered metal base. Multiple horizontal steel bars are installed through the interior of the cross assembly plate.

[0012] As a preferred embodiment of the present invention, the retaining reinforcement assembly further includes: a second hook-shaped body abutting against the outside of the connection between the vertical and horizontal reinforcement bars; and an inclined reinforcement bar integrally formed by welding the second hook-shaped body. The inclined steel bar and the two vertical steel bars form a triangular structure.

[0013] As a preferred embodiment of the present invention, the included angle positioning assembly includes: an L-shaped included angle bracket fixed at the included angle of the vertical frame of the steel structure by screws; a side positioning metal sleeve fixed to the outside of the L-shaped included angle bracket by screws; and a V-shaped metal arm fixed to the side of the side positioning metal sleeve by screws and extending into the interior of the L-shaped included angle bracket. The bottom of the V-shaped metal arm is fixed to the side of the conical metal base by screws.

[0014] In a preferred embodiment of the present invention, the upper and lower sides of the side positioning metal sleeve are provided with rectangular frames that match the L-shaped angle brackets, and a tapered insert extending to the outer angle of the vertical steel frame is provided at the bottom center of the side positioning metal sleeve, the tapered insert being located between the two L-shaped angle brackets. Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In truss-type steel support structures suitable for large-span hollow floor slabs, by setting fully enclosed vertical and horizontal reinforcing bars on the outside of the vertical steel frame, the completed support structure (vertical steel frame and conical metal base) can be supported and fixed, improving the longitudinal and horizontal support strength of the completed support structure (vertical steel frame and conical metal base). Simultaneously, by setting hook-shaped diagonal reinforcing bars at the included angles within the fully enclosed vertical and horizontal reinforcing bars, multiple triangular structures can be created at the included angles within the fully enclosed vertical and horizontal reinforcing bars. These triangular structures further enhance the support strength of the included angles at the edges of the fully enclosed structure, allowing it to withstand greater weight and compressive forces. It should be noted that the structure at the bottom of the truss-type steel support structure will bear greater compressive force due to the compression from the top structure. In this case, the multiple vertical reinforcing bars (5 sets on one side) assembled and fixed can improve the support strength of the conical metal base in both the upper and lower connected states. 2. In truss-type steel bracing structures suitable for large-span hollow floor slabs, by installing and connecting tapered metal bases and L-shaped corner brackets on the sides (front, back, left, and right) and at the four included corners of the vertical steel frame, the number of fixed nodes assembled on the outside of the vertical steel frame can be increased, and the area covered by the nodes can be expanded. This ensures stronger longitudinal tensile and support capabilities when assembling the I-beam longitudinal steel brackets on the sides of the tapered metal base, reducing the probability of deformation or even breakage of the connection between the I-beam longitudinal steel brackets and the tapered metal base due to compression or weight from the upper layer. This enhances the lateral displacement resistance of the truss-type steel bracing structure, ensures balanced load transfer, and avoids local component overload. 3. In truss-type steel support structures applicable to large-span hollow floor slabs, by setting the structure of the second hook-shaped body as a detachable arc-shaped metal arm and hook-shaped metal arm, the specifications and models of the vertical and horizontal steel bars in the assembled and fixed state can be adjusted to ensure that the vertical and horizontal steel bars in the contact state can be tightly contacted with the arc-shaped metal arm and hook-shaped metal arm, and the connection part of the vertical and horizontal steel bars is installed and fixed in a similar way to a full enclosure, which improves the stability and firmness of the assembly and fixing of the connection part of the vertical and horizontal steel bars, and avoids problems such as slippage or even separation of the connection part of the vertical and horizontal steel bars; 4. In truss-type steel support structures applicable to large-span hollow floor slabs, by setting obliquely inclined metal arms inside the longitudinal steel supports and metal diagonal support arms (within the larger triangular area), and dividing the larger triangular area into two smaller triangles and a quadrilateral, the metal diagonal support arms supporting the longitudinal steel supports can be supported and protected, reducing the compressive strength transmitted to the metal diagonal support arms and increasing the strength of the support for the longitudinal steel supports.

[0018] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application. Example 1

[0019] Please see Figures 1-10A truss-type steel support structure suitable for large-span hollow floor slabs includes multiple building foundations 10; a truss steel support assembly structure 30 installed on the outside of the building foundations 10 by screws; and a longitudinal support structure 20 installed on the outside of the truss steel support assembly structure 30 by screws. The truss steel support assembly structure 30 includes: a side assembly component 301 installed and fixed to the side of the building foundation 10; a retaining steel reinforcement assembly 302 that penetrates and is fixed inside the side assembly component 301 and extends to the outside; and an angle positioning assembly 303 installed and fixed inside the side assembly component 301 and installed at the included angle outside the building foundation 10 by screws. The retaining steel reinforcement assembly 302 includes vertical steel bars 3021 and horizontal steel bars 3022. Multiple vertical steel bars 3021 and horizontal steel bars 3022 are provided. Multiple horizontal steel bars 3022 are provided through the side assembly assembly 301. The vertical steel bar 3021 located at the center is installed and fixed inside the center of the side assembly assembly 301. Multiple vertical steel bars 3021 located on the left and right sides of the center are provided on the left and right sides of the side assembly assembly 301. First hook-shaped bodies 3023 are provided on the left and right sides of the horizontal steel bars 3022, and the vertical steel bars 3021 are pressed and fixed on the inner side of the first hook-shaped bodies 3023.

[0020] The working principle described above is as follows: When constructing a large-span hollow core slab building, the building foundation 10 is first installed and laid in the pre-buried soil. This pre-buried method enhances the support strength for the foundation 10. Then, based on the specific height of the building, side assembly components 301 are assembled at multiple locations on the outside of the foundation 10. Using angle positioning components 303 that match the side assembly components 301, the side assembly components 301 and the sides and angles of the foundation 10 are assembled and fixed. This increases the number of nodes for assembling the side assembly components 301 and the area where these nodes are distributed, thereby improving the support strength for the longitudinal support structure 20 and preventing bending or even breakage of the longitudinal support structure 20 after assembly. After the above assembly is completed, horizontal steel bars 3022 and vertical steel bars 3021 are respectively installed through the inside and side of the side assembly component 301. The horizontal steel bars 3022 and vertical steel bars 3021 enhance the overall strength of the assembled and fixed side assembly component 301 and the building foundation 10 (through longitudinal support and compressive force).

[0021] In this invention, the internal structure of the staggered longitudinal support structure 20 is further strengthened through the design of the longitudinal support structure 20, thereby enhancing the internal support strength of the longitudinal support structure 20.

[0022] For details, please refer to the following: Figure 3The building foundation 10 includes: a pre-embedded foundation 101 set in the building pre-embedded area; a steel structure vertical frame 102 installed and fixed on the top of the pre-embedded foundation 101; and a reserved vertical groove 103 opened at the center of the outer side of the steel structure vertical frame 102, wherein the central part of the steel structure vertical frame 102 is set in a cross shape.

[0023] In this invention, the steel structure vertical frame 102 is provided with a protrusion 1021 that is welded and integrally formed perpendicularly to the internal cross-shaped structure on the outside, and a reserved vertical groove 103 is provided on the outer surface of the protrusion 1021. Side assembly components 301 are installed on the outer side and at the included angle of the steel structure vertical frame 102.

[0024] In the truss-type steel support structure applicable to large-span hollow floor slabs of the present invention, the overall structure formed by the steel structure vertical frame 102 and the protrusion 1021 enhances the strength of assembling and fixing the outer side assembly component 301 and increases the contact area of ​​the connection part.

[0025] For details, please refer to the following: Figure 5 The longitudinal support structure 20 includes: an I-beam longitudinal steel bracket 201 fixed to the side of the side assembly 301 by screws; a side metal seat 202 fixed to both sides of the bottom by screws; a metal diagonal support arm 203 installed on the outside of the side metal seat 202; and a central round protrusion 204 welded to the metal diagonal support arm 203 and disposed between the two I-beam longitudinal steel brackets 201, wherein multiple metal diagonal support arms 203 are provided on the outside of the central round protrusion 204.

[0026] In this invention, the central portions of the upper and lower sides of the I-beam longitudinal steel support 201 are fixed with intermediate metal seats 2011 by screws. The left and right sides of the intermediate metal seats 2011 are movably connected with inclined support metal arms 2012. The bottom ends of the inclined support metal arms 2012 are movably installed between two adjacent metal inclined support arms 203. The upper and lower sides of the I-beam longitudinal steel support 201 are also provided with reinforcing steel bars 2013 located on the sides of the intermediate metal seats 2011. The reinforcing steel bars 2013 are installed and fixed on the sides of the vertical steel frame 102. Multiple reinforcing steel bars 2013 are provided.

[0027] In the truss-type steel support structure applicable to large-span hollow floor slabs of the present invention, by constructing multiple obliquely staggered metal diagonal support arms 203 between two I-beam longitudinal steel supports 201, the triangular structure formed by the staggered metal diagonal support arms 203 and the I-beam longitudinal steel supports 201 can be enhanced, thereby increasing the strength of the support for the I-beam longitudinal steel supports 201. Simultaneously, within the triangular structure formed by the larger area of ​​the metal diagonal support arms 203 and the I-beam longitudinal steel supports 201, multiple smaller triangular and quadrilateral regions are divided by oblique support metal arms 2012, distributing the compressive force transmitted to the metal diagonal support arms 203, reducing the intensity of the compressive force transmitted to each metal diagonal support arm 203, and increasing the strength of the support for the I-beam longitudinal steel supports 201.

[0028] For details, please refer to the following: Figure 6 , Figure 7 and Figure 8 The side assembly component 301 includes: a conical metal base 3011 fixed to the outside of the vertical steel frame 102 by screws; a cross assembly plate 3012 welded and fixed to the center of the conical metal base 3011; and a positioning metal protrusion 3013 located at the center of the side of the conical metal base 3011 and extending into the reserved vertical groove 103. An I-beam longitudinal steel bracket 201 is fixed to the side of the conical metal base 3011 away from the positioning metal protrusion 3013 by screws. Angle positioning components 303 are fixed to the left and right sides of the conical metal base 3011 by screws. A set of vertical steel bars 3021 is installed through the center of the conical metal base 3011. Multiple vertical steel bars 3021 are provided on the left and right sides of the conical metal base 3011. Multiple horizontal steel bars 3022 are installed through the interior of the cross assembly plate 3012.

[0029] In the truss-type steel support structure applicable to large-span hollow floor slabs of the present invention, by setting a conical metal base 3011 structure supported and fixed by a cross-shaped assembly plate 3012, the longitudinally assembled conical metal base 3011 can be supported and fixed, thereby improving the support strength of the conical metal base 3011 under external compressive force.

[0030] For details, please refer to the following: Figure 10 The reinforcing bar assembly 302 further includes: a second hook-shaped body 3024 abutting against the outside of the connection between the vertical reinforcing bar 3021 and the horizontal reinforcing bar 3022; and an inclined reinforcing bar 3025 integrally formed by welding the second hook-shaped body 3024, wherein the inclined reinforcing bar 3025 and the two vertical reinforcing bars 3021 form a triangular structure.

[0031] In the truss-type steel support structure applicable to large-span hollow floor slabs of the present invention, the design of the second hook-shaped body 3024 can obliquely reinforce and compress the connection part of the vertical steel bar 3021 and the horizontal steel bar 3022 in the opposing state, ensuring the stability and firmness of the vertical steel bar 3021 and the horizontal steel bar 3022 when they are assembled.

[0032] For details, please refer to the following: Figure 2 The included angle positioning assembly 303 includes: an L-shaped included angle bracket 3031 fixed to the included angle of the vertical steel frame 102 by screws; a side positioning metal sleeve 3032 fixed to the outside of the L-shaped included angle bracket 3031 by screws; and a V-shaped metal arm 3033 fixed to the side of the side positioning metal sleeve 3032 and extending into the inside of the L-shaped included angle bracket 3031 by screws, wherein the bottom of the V-shaped metal arm 3033 is fixed to the side of the conical metal base 3011 by screws.

[0033] In this invention, the upper and lower sides of the side positioning metal sleeve 3032 are provided with rectangular frames 30321 that match the L-shaped angle brackets 3031. The bottom center of the side positioning metal sleeve 3032 is provided with a conical insert 30322 that extends to the outer angle of the vertical steel frame 102. The conical insert 30322 is located between the two L-shaped angle brackets 3031.

[0034] In the truss-type steel support structure of the present invention applicable to large-span hollow floor slabs, the conical insert 30322 is designed to extend between two L-shaped angled supports 3031 and fit against the angled portion on the outside of the vertical steel frame 102. Then, by extending the V-shaped metal arm 3033 into the interior of the rectangular frame 30321 and pushing it into the interior of the L-shaped angled supports 3031 (assembly and fixation via screws), the support strength of the connection between the conical metal base 3011 and the L-shaped angled supports 3031 is increased. Furthermore, multiple assembled and fixed nodes are connected together and fully enclosed on the outside of the vertical steel frame 102, thereby increasing the strength of the vertical steel frame 102 and the conical insert 30322 after assembly and fixation. Example 2

[0035] For details, please refer to the following: Figure 11 The second hook-shaped body 3024 is composed of an arc-shaped metal arm 40 integrally formed by welding with the inclined steel bar 3025 and a hook-shaped metal arm 402 connected to the arc-shaped metal arm 40 by a fixing pin 401. The inner side of the arc-shaped metal arm 40 abuts against the vertical steel bar 3021 and the horizontal steel bar 3022. The inner side of the hook-shaped metal arm 402 is pressed and fixed with the vertical steel bar 3021. The bottom of the hook-shaped metal arm 402 is set above the horizontal steel bar 3022.

[0036] In the truss-type steel support structure of the present invention applicable to large-span hollow floor slabs, when assembling and fixing the vertical steel bars 3021 and horizontal steel bars 3022 in a preliminary connected contact state, firstly, the obliquely arranged diagonal steel bars 3025 are placed inside the vertical steel bars 3021 and horizontal steel bars 3022, and the arc-shaped metal arm 40 connected to the oblique steel bar 3025 abuts against the outside of the horizontal steel bar 3022. Then, the hook-shaped metal arm 402 is fixed inside the arc-shaped metal arm 40 by a fixing pin 401, abutting against the outside of the vertical steel bar 3021 and above the horizontal steel bar 3022, thus achieving a further strengthened and adjustable assembly and fixing operation of the horizontal steel bars 3022 and vertical steel bars 3021.
