Description

Technical Field

[0001] This utility model relates to an installation structure for a detachable diagonal brace embedded part based on a PCF board, belonging to the field of PCF board installation technology. Background Technology

[0002] PCF (Precast Concrete Facade Panel) is short for precast assembled exterior wall panel, a type of concrete component that is prefabricated and cured in a factory. As a precast component, PCF panel cannot bear weight or be fixed independently; its installation requires temporary fixing and precise positioning. Temporary fixation: After the PCF slab is hoisted into place, it needs to be connected to the main building structure (such as floor slabs and beams) through diagonal bracing to resist wind loads and construction loads and prevent the slab from tilting or shifting.

[0003] Precise positioning: The length of the diagonal brace is adjustable. By adjusting the support height and angle of the embedded connection point, the plane position, verticality and elevation of the PCF plate can be finely adjusted to ensure installation accuracy.

[0004] Traditional PCF slab support often adopts the "one-time embedded parts + fixed diagonal braces" model. The embedded parts are permanently bonded to the PCF slab concrete, which can easily damage the slab structure when removed. The diagonal braces cannot be recycled, resulting in steel waste. Summary of the Invention

[0005] The purpose of this utility model is to provide an installation structure for a detachable diagonal brace embedded part based on PCF board. Through the design of "pre-embedded sleeve + detachable connector", only bolt connection is required during installation. After the wall panel is poured, the U-shaped steel bar and the first-level joint can be removed and reused, reducing material consumption, and eliminating the need for steel bar cutting.

[0006] The present invention adopts the following technical solution: An installation structure for a detachable diagonal brace embedded in a PCF (polycarbonate) panel includes a steel plate 1 with a nut and a primary connector 4. The steel plate 1 is embedded in a precast wall panel. The left end of the primary connector 4 is screwed and fixed to the nut on the steel plate 1, and the right end is flush with the inner side of the precast wall panel. The structure also includes a pre-embedded sleeve 10, a threaded straight steel bar 9, a threaded U-shaped steel bar 8, and a secondary connector 7. The pre-embedded sleeve 10 is fitted over the straight steel bar 9, with its left end threaded to the primary connector 4 and its right end threaded to the left end of the secondary connector 7. The U-shaped steel bar 8 is threaded to the right end of the secondary connector 7. The length of the pre-embedded sleeve 10 is equal to the width of the cast-in-place concrete layer 6.

[0007] Preferably, the threads on both sides of the secondary connector 7 are in opposite directions.

[0008] Preferably, the threaded straight steel bars 9 are a parallel pair, and correspondingly, the embedded sleeves 10 are also a parallel pair.

[0009] Preferably, the pre-embedded sleeve 10 is a PVC sleeve.

[0010] Preferably, the precast wall panel is a precast wall panel with an insulation layer, and the right end of the primary joint 4 is flush with the right side of the insulation layer.

[0011] Preferably, it also includes a diagonal bracing component, the upper end of which is fixedly connected to the U-shaped steel bar 8 via a clamping component.

[0012] Furthermore, the lower end of the diagonal brace is hinged to the upper part of the floor slab at the structural elevation via a hinged seat.

[0013] Preferably, a waterproof component is provided between the prefabricated wall panel and the lower wall panel.

[0014] The beneficial effects of this utility model are as follows: 1) Installation only requires bolt connections, eliminating the need for cutting reinforcing bars, making the operation simple; 2) After the wall panel is poured, the U-shaped steel bars, first-level joints and straight steel bars can be removed and reused to reduce material consumption.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] Example 1 (Comparative Example): This embodiment describes a PCB-based inclined brace embedding installation structure and installation process for transmission. See [link to relevant documentation]. Figure 1-6 : Figure 1 The image shows the installed position. The steel plate 1 with nuts is embedded in the precast wall panel. The primary connector 4 is a steel sleeve structure, threadedly connected to the nut in the steel plate 1. It is ensured that the right end of the primary connector 4 is flush with the insulation layer. Figure 2 As shown.

[0030] See Figure 3-4 After the formwork is erected, the U-shaped steel bar 5 is passed through the formwork and further inserted from the right end of the first-level joint 4. At the same time, the U-shaped steel bar 5 is fixed to the diagonal brace. It should be noted that the U-shaped steel bar 5 is fixed to the diagonal brace by setting a clamping component at the upper end of the diagonal brace to clamp the U-shaped steel bar. Since this structure is existing technology, it is not shown in the attached drawings.

[0031] See Figure 5-6 After the concrete cast-in-place layer 6 is poured, the diagonal bracing and formwork are removed, and the U-shaped steel bars 5 protruding from the concrete cast-in-place layer 6 are cut off, forming a shape like... Figure 5 The structure.

[0032] Example 2 (Example of this utility model): Example 2, as a preferred embodiment of this utility model, is described in detail below: See Figure 7-12 An installation structure for a detachable diagonal brace embedded in a PCF (polycarbonate) panel includes a steel plate 1 with a nut and a primary connector 4. The steel plate 1 is embedded in a precast wall panel. The left end of the primary connector 4 is screwed and fixed to the nut on the steel plate 1, and the right end is flush with the inner side of the precast wall panel. The structure also includes a pre-embedded sleeve 10, a threaded straight steel bar 9, a threaded U-shaped steel bar 8, and a secondary connector 7. The pre-embedded sleeve 10 is fitted over the straight steel bar 9, with its left end threaded to the primary connector 4 and its right end threaded to the left end of the secondary connector 7. The U-shaped steel bar 8 is threaded to the right end of the secondary connector 7. The length of the pre-embedded sleeve 10 is equal to the width of the cast-in-place concrete layer 6.

[0033] It should be noted that the terms "left" and "right" in this embodiment are based on the appendix. Figure 7-12 The description is presented to help the reader understand that the left and right directions are actually interchangeable.

[0034] In this embodiment, see Figure 8 The threads on both sides of the secondary connector 7 are in opposite directions.

[0035] In this embodiment, see Figure 8 , 10 12, the threaded straight steel bars 9 are a pair of parallel ones, and correspondingly, the embedded sleeves 10 are also a pair of parallel ones.

[0036] In this embodiment, see Figure 8 , 10 12, the pre-embedded sleeve 10 is a PVC sleeve.

[0037] In this embodiment, see Figure 8 , 10 12, the precast wall panel is a precast wall panel with a thermal insulation layer, and the right end of the primary joint 4 is flush with the right side of the thermal insulation layer.

[0038] See Figure 7-8 It also includes a diagonal bracing component, the upper end of which is fixedly connected to the U-shaped steel bar 8 via a clamping component.

[0039] See Figure 7 , 9 The lower end of the diagonal brace is hinged to the upper part of the floor slab at the structural elevation via a hinge seat.

[0040] See Figure 9 , 11 A waterproof component is provided between the prefabricated wall panel and the lower wall panel.

[0041] In practice, Figure 7-8 The installation status is shown. The primary connector 4 and steel plate 1 are the same as in Example 1. The difference is that a pre-embedded sleeve 10, a threaded straight steel bar 9, and a secondary connector 7 are used. At the same time, the U-shaped steel bar 8 is designed to be shorter and threaded so that it can be threadedly connected to the secondary connector 7.

[0042] See Figure 9-10 First, the straight reinforcing bar 9 is fitted with the pre-embedded sleeve 10 and then threaded to the primary joint 4. Next, the formwork is erected, with the formwork passing through the straight reinforcing bar 9. Then, the right end of the straight reinforcing bar 9 is threaded to the left end of the secondary joint 4. Finally, the U-shaped reinforcing bar 8 is threaded to the right end of the secondary joint 7. Finally, the diagonal bracing structure is fixedly connected. It should also be noted that the U-shaped reinforcing bar 8 is fixed to the diagonal bracing by setting a clamping component at the upper end of the diagonal bracing to hold the U-shaped reinforcing bar 8. Since this structure is existing technology, it is attached... Figure 9 and 10 It was not shown in the document.

[0043] See Figure 11 After the cast-in-place concrete layer 6 is poured, the diagonal bracing and formwork are removed, and the U-shaped steel bar 8 and the secondary joint 7 are removed in sequence. Then the straight steel bar 9 is pulled out, and the pre-embedded sleeve 10 is left inside the cast-in-place concrete layer 6. The entire cast-in-place process based on the PCF slab is completed.

[0044] In this embodiment, core components such as diagonal bracing rods, straight reinforcing bars 9, and U-shaped reinforcing bars 8 can be reused multiple times and can maintain high positioning accuracy.

[0045] In summary, this utility model only requires bolt connection during installation, eliminating the need for cutting the reinforcing bars, making the operation simple. After the wall panel is poured, the U-shaped reinforcing bars, primary joints, and straight reinforcing bars can be removed and reused, reducing material consumption. The construction process is a dry operation, making it highly applicable, more efficient and energy-saving, and environmentally friendly and convenient.

[0046] The above are preferred embodiments of the present utility model. Those skilled in the art can make various changes or improvements based on this. Without departing from the overall concept of the present utility model, these changes or improvements should fall within the scope of protection claimed by the present utility model.
