Description

Technical Field

[0001] This utility model relates to a PCF board demolding diagonal brace embedded part, and more particularly to a detachable and assembleable PCF board demolding diagonal brace embedded part, belonging to the field of precast component on-site construction technology. Background Technology

[0002] Precast concrete facade (PCF) panels are non-load-bearing exterior wall components used in prefabricated buildings. They consist of a concrete protective layer and an insulation layer, serving as insulation, decoration, and formwork. After installation, they must be integrated with the cast-in-place concrete structure and cannot bear weight independently.

[0003] Due to the requirement for continuous insulation in ultra-low energy buildings, the number of precast PCF (polycarbonate) panels has increased. Traditionally, the demolding bracing for precast PCF panels uses round steel lifting rings. This presents the following problems:

[0004] First, due to its height, it cannot enter or exit the curing kiln on the production line, resulting in low factory production efficiency.

[0005] Secondly, round steel lifting rings cannot be positioned using tooling, resulting in significant production errors. On-site formwork sealing construction requires opening large holes at the lifting ring positions, necessitating secondary sealing.

[0006] Third, the finished surface of the concrete after pouring is poor due to the opening in the formwork at the lifting ring location.

[0007] Fourth, after construction is completed, the portion of the lifting ring extending beyond the wall must be cut off, and the wall surface must be repaired a second time. Summary of the Invention

[0008] The purpose of this invention is to provide a detachable and assembleable PCF board demolding brace embedded part to solve the above-mentioned technical problems.

[0009] The present invention adopts the following technical solution:

[0010] A detachable and assembleable PCF slab demolding diagonal brace embedded part includes an embedded part and a detachable pull ring 4; the embedded part includes two embedded rods 202 and a connecting plate component 201; one end of each of the two embedded rods 202 extends in opposite directions and is embedded in the PCF slab precast component 5 to form an embedded section, and the other end of each is bent and extends out to the part of the post-cast concrete 1 to form an extended section; the connecting plate component 201 connects the two embedded rods 202 together and is provided with a lifting hole 201a for demolding; a threaded sleeve 203 is fixedly installed on the extended section of one of the embedded rods 202; the detachable pull ring 4 includes a threaded connecting section 401 for threaded connection with the threaded sleeve 203, and a pull ring 402 for connection with the diagonal brace.

[0011] Preferably, the extended sections of the two pre-embedded rods 202 are parallel to each other and perpendicular to the template 3, and the connecting plate component 201 is square.

[0012] Furthermore, a small anchoring assembly is fixedly installed on the extended section of one of the pre-embedded rods 202, and the threaded sleeve 203 is fixed on the small anchoring assembly.

[0013] Furthermore, the small anchoring component is a plate-type anchoring component.

[0014] Preferably, the different embedded rods 202 have the same length of embedded section, while the extended section has various different lengths depending on the wall thickness.

[0015] Preferably, the threaded sleeve is an M20 threaded sleeve.

[0016] Furthermore, the diameter of the detachable pull ring 4 is D20.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1) The pre-embedded parts for the demolding brace of the PCF plate adopt a combination of threaded sleeve and detachable pull ring, which can be disassembled and reused.

[0019] 2) For threaded sleeve assemblies, positioning fixtures can be used during pre-embedding to ensure accurate pre-embedding positions;

[0020] 3) In the disassembled state, the overall height of the demolding brace embedded part can be shortened, which can avoid the height limit of the curing kiln on the production line, and can produce and enter the kiln for curing on the production line, thus improving production efficiency.

[0021] 4) Improved precision can avoid repeated hole opening of the on-site sealing template, thus avoiding template waste.

[0022] 5) The template for on-site sealing only needs to have a hole diameter of D25 (slightly larger than the diameter of the detachable pull ring) to ensure that the detachable pull ring can be passed through and screwed in, which can avoid the process of sealing the template again after the pull ring is made on-site;

[0023] 6) It avoids the later cutting process of the pull ring, improving work efficiency and the finished surface effect of the post-poured concrete. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0031] After the PCF (precast concrete cladding) panels are poured and cured in the factory steel mold, the formwork needs to be opened and the components lifted out. Once the formwork is released, there are no support points on the outside of the wall panel, so a "handle" must be embedded in the top of the component beforehand to allow the formwork or temporary support to hook onto it and resist outward tilting. This "handle" is the temporary stress point during demolding—referred to as the "demolding" function.

[0032] After the wall panels are delivered to the construction site and installed, there are still cast-in-place sections on the inside that have not been sealed with formwork. At this time, the wall panels are only fixed by a few grouting sleeves or bolts at the bottom. To prevent them from being overturned by pouring concrete, vibration, or wind loads, an adjustable steel pipe (diagonal brace) is used to support them diagonally from the floor (ground) to the upper middle part of the wall panel. The head of the diagonal brace must have a sturdy "hook" or "pin connection point," which is also the same embedded part, hence the term "diagonal brace."

[0033] Therefore, a single embedded part that simultaneously functions as a "demolding" component in the factory and a "brace" component on the construction site is called a "demolding brace embedded part." Thus, the "demolding brace embedded part" is a concept within the existing technology.

[0034] This embodiment introduces a special type of demolding brace embedded part—a detachable and assembleable PCF board demolding brace embedded part.

[0035] See Figure 1 A detachable and assembleable PCF board demolding brace embedded part includes a pre-embedded part and a detachable pull ring 4; the pre-embedded part includes two pre-embedded rods 202 and a connecting plate component 201.

[0036] Combination Figure 2 , Figure 2 This demonstrates the construction and application effect of this utility model during post-cast concrete construction.

[0037] Two pre-embedded rods 202 each extend in opposite directions at one end and are pre-embedded in the precast PCF slab component 5 to form an embedded section. The other end of each rod is bent and extends out to the part where the concrete is poured later to form an extended section. The connecting plate component 201 connects the two pre-embedded rods 202 and has a lifting hole 201a for demolding. The lifting hole 201a is different from the prior art in that it maintains a square structure, so that a threaded sleeve 203 perpendicular to the template 3 can be fixed.

[0038] Specifically, continue to combine Figure 1 One of the pre-embedded rod members 202 has a threaded sleeve 203 fixedly installed on its extended section; the detachable pull ring 4 includes a threaded connection section 401 for threaded connection with the threaded sleeve 203, and a pull ring 402 for connection with the diagonal brace. The pull ring 402 is detachable. Figure 2 Although the pull ring 402 is shown in the diagram, it is actually not present before the template 3 is installed, which would significantly reduce the structural height of the entire prefabricated component.

[0039] The extended sections of the two pre-embedded rods 202 are parallel to each other and perpendicular to the template 3, and the connecting plate component 201 is square.

[0040] See also Figure 2 and combined Figure 1 A small anchoring assembly is fixedly installed on the protruding section of one of the pre-embedded rods 202, and the threaded sleeve 203 is fixed on the small anchoring assembly. Specifically, the small anchoring assembly is a plate-type anchoring assembly.

[0041] In this embodiment, see Figure 1 (a) The different pre-embedded rods 202 have the same length of pre-embedded section, and the extended section has various different lengths depending on the wall thickness.

[0042] The threaded sleeve is an M20 threaded sleeve.

[0043] The diameter of the detachable pull ring 4 is D20.

[0044] During actual production and construction, the following steps should be followed:

[0045] S1. PCF board production formwork, pre-embedded with detachable and assembleable PCF board demolding diagonal brace embedded parts, and use positioning fixtures for precise positioning.

[0046] S2. Pour concrete and send it to the curing kiln for curing after pouring;

[0047] S3, PCF plate components are demolded and lifted, and φ20 detachable pull rings are installed;

[0048] S4 and PCF slab components were transported to the site and hoisted to complete the installation of diagonal bracing rods.

[0049] S5, PCF slab location: on-site reinforcement binding, formwork sealing and concrete pouring;

[0050] S6. After the post-cast concrete has set, remove the railing formwork;

[0051] S7. Remove the detachable pull ring and return it to the factory for reuse.

[0052] The innovation of this utility model can be understood from the entire process steps: the PCF board demolding brace embedded part adopts a combination of threaded sleeve and detachable pull ring, which can be disassembled and reused; the threaded sleeve combination allows the use of positioning fixtures during production to confirm the accurate embedded position; in the disassembled state, the overall height of the demolding brace embedded part can be shortened, which can avoid the height limitation of the curing kiln on the production line, enabling production and curing in the kiln on the production line and improving production efficiency; after the accuracy is improved, it can avoid repeated drilling of the on-site sealing template, which would cause template waste; the on-site sealing template only needs to have a hole diameter of D25 (slightly larger than the diameter of the detachable pull ring) to ensure that the detachable pull ring can be screwed in, which can avoid the process of re-sealing the template after the pull ring is drilled; it avoids the later cutting process of the pull ring, improving work efficiency and the finished surface effect of the poured concrete.

[0053] This utility model improves the problem of PCF boards being unable to enter or exit the curing kiln of the production line due to excessively high lifting rings; it improves the problem of large openings in the on-site sealing template caused by pre-embedded errors in the production of PCF boards with lifting rings; it improves the problem of PCF boards requiring secondary cutting on-site because the lifting rings exceed the wall surface; and it improves the problem of subsequent secondary wall repairs after the above-mentioned problems of "large openings" and "secondary cutting" caused by the lifting rings of PCF boards.

[0054] 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 all fall within the scope of protection claimed by the present utility model.
