Description

Technical Field

[0001] The invention relates to the technical field of construction of steel pipe external scaffolding wall connecting pieces at a construction site, in particular to a method for solving the problem of being unable to arrange wall connecting pieces on a construction layer by adopting an oblique pulling method. Background Art

[0002] Wall ties for external steel tube scaffolding are components that reinforce the stability of other structures by connecting to secure fixed ends. They are used to connect the scaffolding frame to the main building structure during construction, and are capable of transmitting tension and compression. The wall connection achieved with horizontal scaffolding steel tube wall ties and the building's surrounding structure plays a crucial role in strengthening the scaffold's overall stability, improving its stable load-bearing capacity, and preventing major accidents such as toppling or collapse. They are one of the most critical components for ensuring scaffolding safety.

[0003] On floors under construction, according to safety regulations, external scaffolding must be erected before construction and must be a certain height above the highest operating surface to provide safety protection for construction activities. However, since the main structure concrete of the floor under construction has not yet been poured, the wall ties cannot be set up as required. There is currently no effective way to solve this problem.

[0004] At construction sites, it is often the case that entire construction layers are not equipped with wall ties, which violates the provisions of the "Standards for Determining Major Production Safety Accident Hazards in Housing and Municipal Engineering" (Construction Quality Regulation No. 5, 2024), resulting in major production safety accident hazards on site.

[0005] What's worse, connecting the external scaffolding with the formwork frame on the construction floor is a safety measure to stabilize the external frame. This method seriously violates the mandatory provisions of the current relevant specifications. Summary of the Invention

[0006] (1) Technical problems solved

[0007] In response to the shortcomings of the existing technology, the present invention provides a method that uses a diagonal pulling method to solve the problem that wall ties cannot be set up on the construction layer, thereby solving the common safety hazards and common problems such as no wall ties are set up on the entire construction layer and the external frame is connected to the formwork frame. There is currently no effective way to solve this problem.

[0008] (2) Technical solution

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: a method of using an oblique-stayed method to solve the problem of being unable to set up wall ties on the construction layer. Before the concrete of the construction layer structure is poured, the wall ties cannot be connected and tied. The embedded parts in the floor slab structure of the lower layer are used as connection points, and an oblique-stayed steel pipe method is used to solve the problem. The specific construction process is: positioning and laying out the lines and installing the embedded parts during the construction of the lower layer of the construction layer → after the concrete of the lower layer is poured, the external frame is erected, and the oblique-stayed steel pipe is connected and installed → construction layer construction → after the construction layer construction is completed, the oblique-stayed steel pipe is removed after the wall ties are set up → before the concrete of the construction layer is poured, the construction is circulated upward layer by layer.

[0010] 1. When constructing the floor slab structure below the construction layer, pre-embedded parts are embedded in the floor slab. Before pouring the concrete of the next layer, the anchor end of the embedded part is installed below the surface reinforcement of the floor slab structure and above the upper reinforcement. It is required to be anchored to a certain depth in the floor slab structure, with one end exposed above the floor structure slab surface for connecting and fixing the inclined steel pipe;

[0011] 2. After the concrete pouring of the floor slab structure on the lower floor is completed and the concrete reaches a certain strength, and the external scaffolding is erected to the height specified in the special construction plan, the scaffolding steel pipe is used to connect the external scaffolding frame to the exposed end of the embedded parts in an oblique direction;

[0012] 3. After the concrete pouring of the exterior wall and floor slab structure of the construction layer is completed and the wall connection parts of the external scaffolding are set up, the inclined steel pipes can be removed.

[0013] (3) Beneficial effects

[0014] The present invention provides a method for resolving the problem of being unable to install wall ties on the construction floor using an oblique-stayed method. This method has the following beneficial effects: It solves the problem of being unable to install wall ties on the construction floor because the main structure concrete of the floor under construction has not yet been poured, thus preventing the installation of wall ties according to conventional requirements. It also eliminates the currently prevalent safety hazards of major production accidents caused by the lack of wall ties on an entire floor, and the connection of external scaffolding to formwork frames in violation of mandatory provisions of current regulations. It also ensures the stability of the external scaffolding and guarantees construction safety. This method is reliable, simple, economical, highly practical, and suitable for large-scale promotion.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 、 Figure 2 The present invention provides a technical solution: a method for solving the problem of being unable to set up wall ties on the construction layer by using a diagonal-stayed method. The specific construction process is: positioning and laying out, setting up embedded parts during the construction of the layer below the construction layer → erecting the external frame, connecting and installing the diagonal-stayed steel pipes after the concrete of the layer below is poured → construction of the construction layer → removing the diagonal-stayed steel pipes after the wall ties are set up after the construction of the construction layer is completed → setting up embedded parts before pouring concrete on the construction layer, and carrying out the construction in a circular manner upwards layer by layer.

[0020] 1. When constructing the floor slab structure below the construction layer, pre-embedded parts are embedded in the floor slab. Before pouring the concrete of the next layer, the anchor end of the embedded parts is set below the surface steel bars of the floor slab structure and above the upper steel bars. It is required to be anchored to a certain depth in the floor slab structure. The specific operation is as follows: (1) Pre-process and manufacture embedded parts in advance. The embedded parts can be steel anchor rings, short steel pipes, thick steel bar heads, etc., which can ensure the fixation of the inclined steel pipe and meet the strength requirements; See also Figure 3 When using steel anchor rings, use φ16~20 steel bars to make them into a “F” shape, with the length of each bent anchor on both sides not less than 100mm, the width of the anchor ring is about 100mm, and the height is about 160mm; See also Figure 4 When using short steel pipes or thick steel bar heads, the steel pipes shall be of the same specifications as the outer frame, and the length of the steel pipes shall not be less than 150mm. The thick steel bars shall be of a diameter of φ25 or more, and the length shall not be less than 150mm. (2) When constructing the floor slab structure below the construction layer, before pouring concrete, embedded parts are installed in the floor slab. The anchor end of the embedded part is installed below the surface reinforcement of the floor slab structure and above the upper reinforcement. It is required to be anchored to a certain depth in the floor slab structure, and one end is exposed above the floor structure slab surface for connecting and fixing the inclined steel pipe; Before embedding, first locate and lay out the lines. The distance between the embedded parts and the outside of the outer frame should be smaller than the horizontal projection size of the inclined steel pipe. See also Figure 3 When using steel anchor rings, the anchor rings must be anchored into the concrete to a depth of no less than 60mm and must be firmly fixed to the upper and lower layers of steel bars during installation; See also Figure 4 When using short steel pipes or thick steel bar heads, the depth of embedding in concrete shall not be less than 60, and they shall be firmly fixed to the upper and lower layers of steel bars during installation. The short steel pipes or thick steel bar heads can be tilted in the opposite direction to the inclined steel pipe, that is, the anchor end of the embedded part forms an acute angle with the inclined steel pipe;

[0021] 2. After the concrete pouring of the floor slab structure below is completed and the concrete reaches a certain strength, and the external scaffolding is erected to the height specified in the special construction plan, the scaffolding steel pipe is used to connect the external scaffolding frame to the exposed end of the embedded parts in an oblique direction. The specific operation is as follows: See also Figure 1 、 Figure 2 , the steel pipes connecting the external scaffolding frame and the exposed ends of the embedded parts are scaffolding steel pipes, and the outer sides of the steel pipes are connected to the frame at an oblique angle. The height of the connection part is the same as the height of the wall connection parts in the special plan, and the connection method is steel pipe fasteners. The floors are connected with embedded parts, and steel pipe fasteners are used to lock the inclined steel pipes and embedded parts. When the fasteners cannot be locked, welding can also be used to secure them.

[0022] 3. After the concrete pouring of the exterior wall and floor slab structure of the construction layer is completed and the wall connection parts of the external scaffolding are set up, the inclined steel pipes can be removed.

[0023] When constructing each layer, the above method is used to carry out construction in a circular manner layer by layer.

[0024] The inclined steel pipes should be installed as much as possible at the exterior wall balconies, door and window openings, and subsequent masonry walls to reduce the number of holes reserved on the concrete exterior wall.

[0025] During specific implementation: the number and spacing of the inclined steel pipes shall not be less than the spacing and number specified in the special plan for external scaffolding. The specific verification shall be carried out in accordance with the relevant specifications and encrypted when necessary. The deflection of the inclined steel pipes must be verified and the requirements shall be met by adjusting the length and inclination of the inclined steel pipes. If necessary, double steel pipes shall be used together.

[0026] To sum up, the inclined-stayed method solves the problem that wall ties cannot be set up on the construction floor, and solves the problem that wall ties cannot be set up according to conventional requirements because the main structure concrete of the floor under construction has not yet been poured; it fundamentally solves the current common safety problems such as the major production safety accident hazards caused by the lack of wall ties on an entire floor, and the connection between the external scaffolding and the formwork frame in violation of the mandatory provisions of the current specifications; it ensures the stability of the external scaffolding and guarantees construction safety.
