Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to an integrated device and construction method for edge formwork railings used in composite floor slabs. Background Technology

[0002] Composite floor slabs are monolithic floor slabs formed by combining precast slabs and cast-in-place concrete. In prefabricated concrete structures, precast slabs are typically supported by corbels (short cantilevered sections extending outward from the column to support the beam) of precast beams or columns. For example, the top surface of the precast beam serves as the supporting surface for the precast slab, with the slab ends welded or grouted to the beam via embedded parts, forming rigid or hinged joints. Construction workers then erect formwork on the sides of the supporting surface composed of the precast slab and precast beam, and construct external scaffolding to ensure safety before beginning the cast-in-place concrete pouring.

[0003] It is evident that in the current practice, the construction of precast slabs and the pouring of cast-in-place concrete are independent and disconnected. After the precast slabs are constructed, cumbersome procedures such as side formwork erection and scaffolding installation must be completed before cast-in-place concrete can be poured. Furthermore, after construction is completed and it is confirmed that there is no risk of falls from height, the scaffolding must be dismantled. To meet project deadlines or improve construction efficiency, it is crucial to reduce the number of steps between precast slab construction and cast-in-place concrete pouring while ensuring personnel safety, and to enhance the continuity between the two processes. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an integrated device and construction method for edge formwork railings for composite floor slabs, which reduces the construction steps from precast slab construction to cast-in-place concrete, while ensuring the personal safety of construction personnel and improving the tightness of process connection.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An integrated edge formwork railing device for composite floor slabs includes precast beams and railing components; The precast beam has a precast side mold on its beam surface side. The railing assembly is rotatably mounted on the side of the precast beam corresponding to the precast side mold. When the railing assembly rotates upward, it has an unfolded state that can form a guardrail on the beam surface side of the precast beam. When the railing assembly is in the unfolded state, the height of the guardrail formed by the railing assembly is higher than the precast side mold, and the precast side mold is detachably connected to the railing assembly.

[0006] To solve the above-mentioned technical problems, another technical solution adopted by the present invention is as follows: A construction method for an integrated edge formwork railing device for composite floor slabs, applied to the aforementioned integrated edge formwork railing device for composite floor slabs, includes the following steps: S1. Precast slabs of composite floor slabs are supported by columns and precast beams at the construction site; S2. Rotate the railing assembly on the precast beam so that the railing assembly enters the unfolded state; S3. Connect the precast side mold on the precast beam to the railing assembly, so that the railing assembly remains in the unfolded state; S4. With the railing components in different positions providing safety protection, the cast-in-place concrete work of the composite floor slab is completed.

[0007] The beneficial effects of this invention are as follows: It provides an integrated edge formwork and railing device and construction method for composite floor slabs. Precast edge formwork and railing components are pre-set on precast beams to achieve integrated edge formwork and railing. When the precast slab is erected, the railing components on the precast beams in different positions can be unfolded to form protection around the precast slab. No additional side formwork or external equipment construction is required, reducing the construction steps from precast slab erection to cast-in-place concrete for composite floor slabs, while ensuring the personal safety of construction personnel. Concrete can be cast in place after the railing components are unfolded, improving the tightness of process connection. Attached Figure Description

[0010] To explain in detail the technical content, objectives, and effects of the present invention, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0011] Please refer to Figures 1 to 8 An integrated edge formwork railing device for composite floor slabs includes a precast beam 1 and a railing assembly 2. The precast beam 1 has a precast side mold 3 on the side of the beam surface. The railing assembly 2 is rotatably mounted on the side of the precast beam 1 corresponding to the precast side mold 3. When the railing assembly 2 rotates upward, it has an unfolded state that can form a guardrail on the side of the beam surface of the precast beam 1. When the railing assembly 2 is in the unfolded state, the height of the guardrail formed by the railing assembly 2 is higher than that of the prefabricated side mold 3, and the prefabricated side mold 3 is detachably connected to the railing assembly 2.

[0012] As can be seen from the above description, the beneficial effects of the present invention are as follows: by pre-setting the precast side formwork 3 and the railing assembly 2 on the precast beam 1, the side formwork and railing are integrated. When the precast slab 4 is built, the railing assembly 2 on the precast beam 1 in different positions can be unfolded to form protection around the precast slab 4. There is no need for additional side formwork, external equipment construction and other processes, which reduces the construction process of the composite floor slab from the precast slab 4 to the cast-in-place concrete, and at the same time ensures the personal safety of construction personnel. After unfolding the railing assembly 2, the concrete can be cast in place, which improves the tightness of the process connection.

[0013] Furthermore, the railing assembly 2 includes a first upright post 21, a second upright post 22, and a crossbar 23; The bottom ends of the first upright 21 and the second upright 22 are rotatably connected to the side of the precast side mold 3, and the two ends of the crossbar 23 are rotatably connected to the first upright 21 and the second upright 22, respectively.

[0014] As can be seen from the above description, the railing assembly 2 adopts a structural design of a first upright 21, a second upright 22, and a horizontal bar 23. The uprights are rotatably connected to the side of the precast side mold 3, and the horizontal bar 23 is rotatably connected to the uprights, making the railing assembly 2 more flexible and stable in the process of unfolding and storing.

[0015] Furthermore, it also includes a limiting element 24; The limiting member 24 is disposed on the top end of the first upright 21, the top end of the second upright 22, and / or on the side of the crossbar 23 facing the precast beam 1; The limiting member 24 corresponds vertically to the prefabricated side mold 3, and the limiting member 24 is used to press against the prefabricated side mold 3 when the railing assembly 2 rotates downward.

[0016] As can be seen from the above description, the setting of the limiting member 24 enables the railing assembly 2 to press against the precast side mold 3 when it rotates downwards for storage, thereby achieving stable storage of the railing assembly 2 and preventing it from rotating downwards and colliding with other objects during transportation. In particular, when multiple precast beams 1 are transported by stacking blocks, etc., the railing assembly 2 is kept in a stored state, saving transportation space.

[0017] Furthermore, it also includes a sleeve 5 and a connector 6; The two sleeves 5 are embedded in the side of the precast side mold 3, and the two sleeves 5 correspond to the first upright 21 and the second upright 22 respectively; Both the first upright 21 and the second upright 22 are provided with mounting through holes 26 corresponding to the sleeve 5; The connector 6 passes through the mounting through hole 26 in a one-to-one correspondence and is rotatably connected to the sleeve 5.

[0018] As described above, the combined use of sleeve 5 and connector 6 provides a reliable connection method for the rotational connection of the first upright 21 and the second upright 22 with the precast side mold 3. The pre-embedded sleeve 5 enhances the structural strength of the connection part, and the connector 6 passes through the mounting through hole 26 and rotates with the sleeve 5, making the upright rotate smoothly and the connection firm. This connection method not only facilitates the installation and disassembly of the railing assembly 2, but also maintains stable rotational performance during long-term use, reducing the risk of railing assembly 2 failure due to loosening of the connection part, and ensuring construction safety and normal use of the device.

[0019] Furthermore, it also includes gasket 7; The gasket 7 is provided between the first upright 21 and the sleeve 5 and between the second upright 22 and the sleeve 5, and the gasket 7 is sleeved on the connector 6 in a one-to-one correspondence.

[0020] As described above, the shim 7 is placed between the first upright 21, the second upright 22, and the sleeve 5 to reduce resistance. The shim 7 reduces friction between the upright and the sleeve 5 during rotation, reduces component wear, extends the service life of the device, ensures the flexibility and stability of the railing assembly 2's rotation, and makes the railing assembly 2 operate more smoothly during unfolding and retraction.

[0021] Furthermore, there are at least two crossbars 23.

[0022] As described above, the presence of at least two crossbars 23 significantly enhances the overall strength and protective performance of the guardrail assembly 2. Multiple crossbars 23 form a protective barrier at different heights, effectively preventing construction workers from accidentally falling from different angles, further improving the safety level for construction personnel. Simultaneously, the design of multiple crossbars 23 also increases the structural stability of the guardrail assembly 2, making it less prone to deformation or damage when subjected to external impacts, ensuring the safety and reliability of the device throughout the entire construction process.

[0023] Furthermore, it also includes positioning component 8; The prefabricated side mold 3 is provided with a positioning groove 31, and the railing assembly 2 is provided with a positioning through hole 25; When the railing assembly 2 is in the unfolded state, the positioning groove 31 and the positioning through hole 25 correspond to each other, the positioning member 8 is set through the positioning groove 31 and the positioning through hole 25 at the same time, and the positioning member 8 is detachably fixed on the positioning groove 31 and the positioning through hole 25.

[0024] As can be seen from the above description, the use of positioning component 8 in conjunction with positioning groove 31 and positioning through hole 25 enables reliable fixing of prefabricated side mold 3 and railing component 2 when railing component 2 is in the unfolded state; construction personnel can quickly complete the unfolding and fixing of railing component 2, improving construction efficiency.

[0025] Furthermore, it also includes safety ropes; At least two railing assemblies 2 are distributed on the same side of the precast beam 1, and adjacent railing assemblies 2 are connected by the safety rope.

[0026] As described above, the safety rope connects multiple guardrail components 2 distributed on the same side into a whole, further enhancing the safety and stability of the protection system. When a guardrail component 2 is subjected to a large external impact, the safety rope can distribute the force to other guardrail components 2, preventing a single guardrail component 2 from failing due to excessive force and effectively preventing construction workers from falling. The design of the safety rope reduces the requirements for the length of individual guardrail components 2, thus reducing investment costs.

[0027] Please refer to Figure 9 A construction method for an integrated edge formwork railing device for composite floor slabs, applied to the aforementioned integrated edge formwork railing device for composite floor slabs, includes the following steps: S1. At the construction site, columns and precast beams 1 are used to support the precast slabs 4 of the composite floor slab; S2. Rotate the railing assembly 2 on the precast beam 1 so that the railing assembly 2 enters the unfolded state; S3. Connect the precast side mold 3 on the precast beam 1 and the railing assembly 2 so that the railing assembly 2 remains in the unfolded state; S4. With the railing components 2 in different positions providing safety protection, the cast-in-place concrete work of the composite floor slab is completed.

[0028] As can be seen from the above description, the beneficial effects of the present invention are as follows: by pre-setting the precast side formwork 3 and the railing assembly 2 on the precast beam 1, the side formwork and railing are integrated. When the precast slab 4 is built, the railing assembly 2 on the precast beam 1 in different positions can be unfolded to form protection around the precast slab 4. There is no need for additional side formwork, external equipment construction and other processes, which reduces the construction process of the composite floor slab from the precast slab 4 to the cast-in-place concrete, and at the same time ensures the personal safety of construction personnel. After unfolding the railing assembly 2, the concrete can be cast in place, which improves the tightness of the process connection.

[0029] Furthermore, it also includes: S5. After the cast-in-place concrete work on the composite floor slab is completed or the wall construction work on the composite floor slab is completed, the railing assembly 2 is removed.

[0030] As can be seen from the above description, the protective function provided by the railing component 2 can be used continuously until the wall construction is completed, and the railing component 2 can be removed after it is no longer needed. The railing component 2 can be recycled without affecting the overall appearance of the composite floor slab.

[0031] Please refer to Figures 1 to 8 Embodiment 1 of the present invention is as follows: An integrated edge formwork and railing device for composite floor slabs includes a precast beam 1 and a railing assembly 2. A precast edge formwork 3 is integrally formed on the side of the beam surface of the precast beam 1. The railing assembly 2 is rotatably mounted on the side of the precast beam 1 corresponding to the precast edge formwork 3. When the railing assembly 2 rotates upward, it has an unfolded state in which a guardrail can be formed on the side of the beam surface of the precast beam 1. When the railing assembly 2 is in the unfolded state, the height of the guardrail formed by the railing assembly 2 is higher than that of the precast edge formwork 3. The precast edge formwork 3 and the railing assembly 2 are detachably connected.

[0032] In this embodiment, as Figure 2 and Figure 3As shown, the railing assembly 2 includes a first upright 21, a second upright 22, and a crossbar 23; the bottom end of the first upright 21 and the bottom end of the second upright 22 are rotatably connected to the side of the precast side mold 3, and the two ends of the crossbar 23 are rotatably connected to the first upright 21 and the second upright 22, respectively.

[0033] In this embodiment, as Figure 2 As shown, when the first upright 21 and the second upright 22 swing, the two ends of the crossbar 23 are rotatably connected to the first upright 21 and the second upright 22 respectively, causing the entire railing assembly 2 to deform, thus having a retracted state and an extended state. The crossbar 23 can be connected to the first upright 21 and to the second upright 22 using a rotatable connection method such as a hinge. To improve stability and protective strength, there can be two or more crossbars 23.

[0034] Combination Figure 1 and Figure 5 As shown, the limiting member 24 is disposed on the top of the first upright 21, the top of the second upright 22, and / or the side of the crossbar 23 facing the precast beam 1; the limiting member 24 corresponds vertically to the precast side mold 3, and is used to press against the precast side mold 3 when the railing assembly 2 rotates downward. When the railing assembly 2 rotates downward, the limiting member 24 moves accordingly and eventually presses against the precast side mold 3, thereby preventing the railing assembly 2 from continuing to rotate downward and maintaining its retracted state. It can be understood that the limiting member 24 can be disposed on any one, any two, or even all three of the top of the first upright 21, the top of the second upright 22, and the crossbar 23. The limiting member 24 can be a flange structure integrally formed with the railing assembly 2, or it can be an accessory installed on the railing assembly 2 by means of locking or other methods.

[0035] In this embodiment, combined with Figure 3 and Figure 4 As shown, it also includes a positioning element 8; the precast side mold 3 is provided with a positioning groove 31, and the railing assembly 2 is provided with a positioning through hole 25; when the railing assembly 2 is in the unfolded state, the positioning groove 31 and the positioning through hole 25 correspond to each other, and the positioning element 8 is set through both the positioning groove 31 and the positioning through hole 25, and the positioning element 8 is detachably fixed to the positioning groove 31 and the positioning through hole 25. The positioning element 8 is used to connect the precast side mold 3 and the railing assembly 2, so that the railing assembly 2 remains in the unfolded state. Among them, the positioning element 8 can adopt a locking structure such as the bolt sleeve 5 and the connecting bolt cooperating with each other, or it can adopt a restraint structure such as steel rope, hinge, etc.

[0036] Furthermore, when at least two railing assemblies 2 are distributed on the same side of a precast beam 1, or when railing assemblies 2 of precast beams 1 are located in different orientations, adjacent railing assemblies 2 can be connected by safety ropes. It is worth noting that the distance between two railing assemblies 2 connected by safety ropes must not exceed 1.2m to meet building safety regulations.

[0037] Please refer to Figure 7 and Figure 8 Embodiment two of the present invention is as follows: An integrated edge formwork railing device for composite floor slabs, based on the above-described embodiment one, further includes sleeves 5 and connectors 6; two sleeves 5 are pre-embedded in the side of the precast edge formwork 3, and the two sleeves 5 correspond to the first upright 21 and the second upright 22 respectively; the first upright 21 and the second upright 22 are each provided with mounting through holes 26 corresponding to the sleeves 5; the connectors 6 pass through the mounting through holes 26 one by one and are rotatably connected to the sleeves 5.

[0038] Combination Figure 2 , Figure 7 as well as Figure 8 As shown, one end of the sleeve 5 faces the steel cage inside the precast beam 1, while the other end is exposed on the side of the precast side mold 3. The sleeve 5 can be a bolt sleeve 5, and the connector 6 can be a pin, one end of which passes through the mounting through hole 26 and is rotatably connected to the bolt sleeve 5. The connector 6 can be used to lock and fix the lower ends of the first upright 21 and the second upright 22, while the positioning part 8 cooperates with the precast side mold 3 to fix the middle part of the first upright 21 and the middle part of the second upright 22, thereby ensuring that the first upright 21 and the second upright 22 have sufficient support strength in the unfolded state.

[0039] Furthermore, when it is necessary to disassemble the railing assembly 2 in the future, the railing assembly 2 can be disassembled simply by detaching the positioning piece 8 and removing the connecting piece 6, while the sleeve 5 can be left on the precast beam 1.

[0040] Not only that, such as Figure 8 As shown, gaskets 7 are provided between the first upright 21 and the sleeve 5, and between the second upright 22 and the sleeve 5, and the gaskets 7 are fitted onto the connecting parts 6 in a one-to-one correspondence. The materials of the gaskets 7 include, but are not limited to, materials with a low coefficient of friction such as polytetrafluoroethylene, so as to reduce the frictional force experienced by the first upright 21 and the second upright 22 during rotation.

[0041] Please refer to Figure 9 Embodiment 3 of the present invention is as follows: A construction method for an integrated edge formwork railing device for composite floor slabs, applied to an integrated edge formwork railing device for composite floor slabs in Embodiment 1, includes the following steps: S1. At the construction site, columns and precast beams 1 are used to support the precast slabs 4 of the composite floor slab; In this embodiment, combined with Figure 1 As shown, during transportation or on-site assembly, railing component 2 remains in a retracted state; as Figure 6 As shown, at the construction site, the four sides of the precast slab 4 are all equipped with precast beams 1 with railing components 2 and precast side molds 3.

[0042] S2. Rotate the railing assembly 2 on the precast beam 1 so that the railing assembly 2 enters the unfolded state; In this embodiment, as Figure 2 As shown, the operator rotates the connector 6, which in turn rotates the first upright 21 and the second upright 22 upwards; when the positioning through hole 25 and the positioning groove 31 correspond to each other, it indicates that the rotation is in place and the railing assembly 2 enters the unfolded state.

[0043] S3. Connect the precast side mold 3 on the precast beam 1 and the railing assembly 2 so that the railing assembly 2 remains in the unfolded state; In this embodiment, after the operator rotates the railing assembly 2 into place, the positioning part 8 is installed on the positioning through hole 25 and the positioning groove 31. Specifically, the bolt sleeve 5 of the positioning part 8 and the connecting bolt are connected from both sides, so that the connecting bolt passes through the positioning through hole 25 and the positioning groove 31 at the same time. Then, the operator tightens the connecting part 6 on the first upright 21 and the connecting part 6 on the second upright 22, so that the railing assembly 2 remains in the unfolded state.

[0044] S4. With the railing components 2 in different positions forming a safety protection system, the cast-in-place concrete work of the composite floor slab is completed. Adjacent railing components 2 can be connected by safety ropes to form a safety protection system.

[0045] S5. After the cast-in-place concrete work on the composite floor slab is completed or the masonry work on the composite floor slab is completed, remove the railing assembly 2.

[0046] In this embodiment, when it is necessary to disassemble the railing assembly 2, the disassembly of the railing assembly 2 can be completed by simply unlocating the positioning piece 8 and removing the connecting piece 6, while the sleeve 5 can be left on the precast beam 1.

[0047] In summary, this invention provides an integrated edge formwork and railing device and construction method for composite floor slabs. Precast edge formwork and railing components are pre-installed on precast beams, achieving integrated edge formwork and railing. When the precast slab is erected, the railing components on the precast beams in different locations are simply unfolded to form protection around the precast slab, eliminating the need for additional side formwork and external installation. This reduces the construction steps from precast slab erection to cast-in-place concrete pouring, while ensuring the safety of construction workers. Concrete can be poured immediately after unfolding the railing components, improving the tightness of process connections. The railing components adopt a structure of first uprights, second uprights, and horizontal bars. The uprights are rotatably connected to the side of the precast edge formwork, and the horizontal bars are rotatably connected to the uprights, making the structure more flexible and stable during unfolding and retraction. Limiting components are added to maintain the retracted state of the railing components. In the rotating part, sleeves and connectors are used to provide a reliable connection method for the rotational connection of the first and second uprights to the precast edge formwork. The pre-embedded sleeve enhances the structural strength of the connection. The connector passes through the mounting hole and rotates with the sleeve, allowing the upright to rotate smoothly and ensuring a secure connection. This connection method not only facilitates the installation and disassembly of the railing components, but also...

[0048] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent modifications made based on the content of the present invention's specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of the present invention.
