Description

Technical Field

[0001] This invention relates to a scaffolding reinforcement method, and more particularly to a method for constructing a wall tie reinforcement structure for ultra-span and ultra-high areas. Background Technology

[0002] Wall ties are components that connect scaffolding to the building. Generally, wall ties are set at the main nodes where the uprights and horizontal bars of the scaffolding intersect. In order to ensure the stability of the scaffolding and construction safety, the arrangement distance of wall ties is required to be "two steps and three spans". "Two steps and three spans" means that the vertical height of the scaffolding is a maximum of two steps and the horizontal length of the scaffolding is a maximum of three spans.

[0003] In some building projects, there are many structures that exceed the standard "two-step, three-span" range, meaning that the building's floor height and span far exceed the standard "two-step, three-span" range. Ordinary wall ties cannot be pre-embedded, and the column clamping method is not used for reinforcement. The wall ties do not have "rooting points" and cannot meet the standard "two-step, three-span" layout requirements for wall ties. The scaffolding is prone to swaying due to wind loads or the passage of personnel and equipment during construction, posing a risk of overturning and significant safety hazards. Summary of the Invention

[0004] In view of this, the present invention provides a method for constructing a reinforcement structure for ultra-high and ultra-span regional wall ties, comprising:

[0005] S1. Drive the embedded parts of the floor slab near the edge of the floor slab, and set up horizontal wall ties. One end of the horizontal wall tie is connected to the embedded parts of the floor slab, and the other end is connected to the longitudinal bar of the scaffold.

[0006] S2. Install swivel fasteners. The specifications of the swivel fasteners must comply with safety technical specifications to ensure a firm and reliable connection with the embedded parts and tie rods, effectively transmit tensile and compressive forces, and connect the swivel fasteners and the embedded parts of the base plate.

[0007] S3. The swivel coupler and the lower diagonal tie rod are connected. One end of the lower diagonal tie rod is connected to the swivel coupler, and the other end is fixed at the main node formed by the intersection of the horizontal and longitudinal bars of the scaffold. The lower diagonal tie rod, the horizontal wall tie, and the longitudinal bar form a lower triangular stabilizing structure. The lower triangular stabilizing structure includes the upper triangular stabilizing structure mentioned below. Through the principle of geometrically invariant system, part of the horizontal load (such as wind load, construction eccentric load, etc.) borne by the scaffold is effectively transferred to the floor structure, namely the bottom plate and the top plate, which enhances the lateral stability of the scaffold in the ultra-high and ultra-span area and reduces the safety hazards caused by missing or excessively spaced wall ties.

[0008] S4. After the concrete pouring at the top of the floor is completed, install the embedded parts of the top slab below the top slab and install horizontal wall ties. One end of the horizontal wall tie is connected to the outer wall surface at the top of the floor, and the other end is connected to the longitudinal bar of the scaffold.

[0009] S5. Install swivel fasteners and connect the swivel fasteners to the embedded parts in the top plate;

[0010] S6. The swivel fastener and the upper diagonal tie rod are connected. One end of the upper diagonal tie rod is connected to the swivel fastener on the top plate, and the other end is fixed at the main node where the lower diagonal tie rod is fixed. The upper diagonal tie rod and the lower diagonal tie rod are located on the left and right sides of the main node, respectively. The upper diagonal tie rod, the horizontal wall tie and the longitudinal rod form an upper triangular stable structure.

[0011] S7. Repeat the above steps on the next floor to continue building the wall tie reinforcement structure until the project is completed, then remove the scaffolding and wall ties.

[0012] Furthermore, the embedded parts of the base plate are set at the edge of the floor base plate near the scaffolding, and multiple embedded parts of the base plate are arranged in an array along the edge of the floor within a floor span.

[0013] Furthermore, the top slab embedded parts are set at the edge of the floor top slab near the scaffolding, and multiple top slab embedded parts are arranged in an array along the floor edge within a floor span.

[0014] Furthermore, one end of the lower diagonal tie rod is connected and fixed to a swivel coupler, and the pre-embedded part in the base plate is then connected and fixed to the swivel coupler; the other end of the lower diagonal tie rod is fixed at the main node formed by the intersection of the horizontal and vertical bars of the scaffold.

[0015] Furthermore, one end of the upper diagonal tie rod is connected and fixed to a swivel fastener, and the pre-embedded part in the top plate is then connected and fixed to the swivel fastener; the other end of the upper diagonal tie rod is fixed at the main node where the lower diagonal tie rod is fixed, and the upper diagonal tie rod and the lower diagonal tie rod are respectively located on the left and right sides of the main node.

[0016] Furthermore, the horizontal wall tie at the bottom is connected to the embedded part of the base plate at one end and to the longitudinal bar of the scaffold at the other end; the horizontal wall tie is a rigid wall tie and is installed through the wall; holes should be reserved in the wall and properly sealed after installation to ensure the performance of the wall itself.

[0017] Furthermore, one end of the horizontal wall tie installed at the top of the floor is connected to the exterior wall at the top of the floor, and the other end is connected to the longitudinal bar of the scaffold.

[0018] The beneficial effects of this invention are as follows: It provides a method for constructing a wall tie reinforcement structure for ultra-high and ultra-span areas. By setting up alternating triangular stabilizing structures layer by layer, a solid spatial force-bearing system is constructed, which improves the overall rigidity and stability of the scaffolding. It is particularly suitable for construction conditions with high floor height, large span, or limited wall tie installation. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] Figure 1 This is an overall schematic diagram of the reinforcement structure for ultra-high and ultra-span regional wall ties. Detailed Implementation

[0021] In view of this, the present invention provides a method for constructing a reinforcement structure for ultra-high and ultra-span regional wall ties, comprising:

[0022] S1. Drive the pre-embedded part 1 into the floor slab near the edge, and set the horizontal wall tie 2. One end of the horizontal wall tie 2 is connected to the pre-embedded part of the floor slab, and the other end is connected to the longitudinal bar 4 of the scaffold.

[0023] S2. Install swivel fastener 3. The specifications of the swivel fastener must comply with the safety technical specifications to ensure that the connection between it and the embedded part and the diagonal tie rod is firm and reliable, and to effectively transmit tensile and compressive forces. Connect the swivel fastener 3 and the embedded part 1 of the base plate.

[0024] S3. The swivel coupler 3 and the lower diagonal tie rod 7 are connected. One end of the lower diagonal tie rod 7 is connected to the swivel coupler, and the other end is fixed at the main node 5 formed by the intersection of the horizontal bar 6 and the longitudinal bar 4 of the scaffold. The lower diagonal tie rod 7, the horizontal wall tie 2, and the longitudinal bar 4 form a lower triangular stabilizing structure. The lower triangular stabilizing structure includes the upper triangular stabilizing structure mentioned below. Through the principle of geometrically invariant system, part of the horizontal load (such as wind load, construction eccentric load, etc.) borne by the scaffold is effectively transferred to the upper floor structure, which enhances the lateral stability of the scaffold in the ultra-high and ultra-span area and reduces the safety hazards caused by missing or excessively spaced wall ties.

[0025] A geometrically invariant system refers to a rod system whose geometry and position remain unchanged under any load;

[0026] S4. After the concrete pouring is completed at the top of the floor, the top slab embedded part 9 is set under the top slab, and the conventionally installed horizontal wall tie is set. One end of the horizontal wall tie is connected to the top slab embedded part, and the other end is connected to the longitudinal bar of the scaffold.

[0027] S5. Install another swivel fastener and connect the swivel fastener to the pre-embedded part 9 in the top plate;

[0028] S6. The swivel fastener and the upper diagonal tie rod 8 are connected. One end of the upper diagonal tie rod 8 is connected to the swivel fastener on the top plate, and the other end is fixed at the main node 5 where the lower diagonal tie rod is fixed. The upper diagonal tie rod and the lower diagonal tie rod are located on the left and right sides of the main node 5 respectively. The upper diagonal tie rod 8, the horizontal wall tie and the longitudinal rod 4 form an upper triangular stable structure.

[0029] S7. Repeat the above steps on the next floor to continue building the wall tie reinforcement structure until the project is completed, then remove the scaffolding and wall ties.

[0030] In this embodiment, the base plate embedded part 1 is a steel pipe set at the edge of the floor base plate near the scaffolding, and there are multiple base plate embedded parts set along the edge of the floor in a floor span according to the rule of "three spans", that is, if one span is 1.5 meters, then three spans are 4.5 meters, and one base plate embedded part 1 is buried every 4.5 meters.

[0031] In this embodiment, the top plate embedded part 9 is set at the edge of the floor top plate near the scaffolding, and there are multiple top plate embedded parts 9 set along the edge of the floor in a floor span according to the rule of "three spans". The top plate embedded part 9 is also a steel pipe and its position corresponds to the position of the bottom plate embedded part of this floor.

[0032] The embedded parts 1 in the bottom plate and 9 in the top plate can also be made of steel plates, steel sections or special embedded anchors, etc. The embedding depth and the specifications of the embedded parts need to be determined according to the scaffolding load and structural design requirements.

[0033] The initial setting positions of the bottom plate embedded part 1 and the top plate embedded part 9 should be as close as possible to the vertical plane where the main node is located, with a deviation distance not exceeding 300mm; if this requirement cannot be met, the length of one span can be appropriately changed, but the change range cannot exceed the provisions of the relevant construction technical standards.

[0034] In this embodiment, one end of the lower diagonal brace 7 is connected and fixed with a swivel coupler, and the pre-embedded part 1 in the base plate is then connected and fixed with the swivel coupler; the other end of the lower diagonal brace 7 is fixed at the main node formed by the intersection of the transverse bar 4 and the longitudinal bar 6 of the scaffold.

[0035] In this embodiment, one end of the upper inclined tie rod 8 is connected and fixed to a swivel fastener, and the top plate embedded part 9 is then connected and fixed to the swivel fastener; the other end of the upper inclined tie rod 8 is fixed at the main node where the lower inclined tie rod is fixed, and the upper inclined tie rod 8 and the lower inclined tie rod 7 are located on the left and right sides of the main node, respectively;

[0036] The lower and upper diagonal braces should preferably be made of steel pipes, round steel, or steel strands with sufficient tensile strength. The connection and fixation between the lower and upper diagonal braces and the main nodes shall be achieved by fasteners, or by clamps or connecting plates. The connection points should avoid the joints of the scaffolding.

[0037] In this embodiment, one end of the horizontal wall tie 2 at the bottom is connected to the embedded part of the base plate, and the other end is connected to the longitudinal bar 4 of the scaffold. The horizontal wall tie is a rigid wall tie and is installed through the wall. Holes should be reserved in the wall and properly sealed after installation to ensure the performance of the wall itself.

[0038] In this embodiment, one end of the horizontal wall tie at the top of the floor is connected to the outer wall at the top of the floor, and the other end is connected to the longitudinal bar 4 of the scaffold.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
