Description

Technical Field

[0001] The present invention belongs to the technical field of precast bridge construction, and particularly relates to a forming template structure for precast beam slabs. Background Art

[0002] During the bridge construction process, considering construction efficiency and quality, more and more projects adopt the construction method of precast box girders; during the precast process, one of the necessary large-scale construction equipment is the formwork device for box girder pouring; combined with the current intelligent beam factory design, the formwork needs to be quickly demolded when the concrete pouring is completed and meets the demolding conditions, and at the same time, it can be quickly formwork-supported to reduce the formwork removal and support time.

[0003] Most of the existing demolding equipment has a simple structure. In particular, the installation and removal construction of the formwork at the top of the box girder diaphragm is relatively difficult. The traditional formwork for plugging at the diaphragm and the upper comb-shaped plate are integrated, making installation and demolding difficult, resulting in a slow precast speed of beam slabs and affecting the overall construction progress of the project.

[0004] The document with the authorization announcement number CN218535031U discloses a comb-shaped template structure for the top of the diaphragm of precast beam slabs, including: an inverted plug comb-shaped template for inserting along the bridge width direction to the top of the middle diaphragm of the bridge, and a first reserved groove for placing the exposed main reinforcement of the diaphragm and a second reserved groove for placing the exposed stirrups of the diaphragm are reserved on the inverted plug comb-shaped template; two upright comb-shaped templates detachably connected to the opposite outer sides of the inverted plug comb-shaped template through a connection structure, and a third reserved groove for placing the protruding main reinforcement at the top of the wing flange plates on both sides of the bridge is reserved on each of the two upright comb-shaped templates. This structure changes the integrated comb-shaped template into a multi-segment comb-shaped template, which is beneficial to the segmented installation and removal of the formwork, reduces the disassembly and installation difficulty and danger, and improves the construction efficiency.

[0005] However, this solution still has the following problems: First, the comb-shaped plate itself needs to be re-molded and precast, with a high cost; second, the multi-segment comb-shaped template has requirements for the sequence of processes during disassembly, that is, first remove the inverted plug comb-shaped template and then remove the upright comb-shaped template, which is not convenient and fast enough.

[0006] Therefore, the inventor of the present invention has proposed a forming template structure for precast beam slabs to solve the above technical problems. Summary of the Invention

[0007] Aiming at the above existing problems, the purpose of the present invention is to provide a forming template structure for precast beam slabs. On the basis of adopting a split comb-shaped template, the structure of the comb-shaped template itself is simplified, and its mold opening cost is reduced; at the same time, the fixing of the comb-shaped template is completed through the cooperation connection between the fixing fixture and the comb-shaped template, and the installation / removal work of the comb-shaped template can be quickly completed, with the advantage of high work efficiency.

[0008] The specific technical solution of the present invention is as follows: A precast beam and slab forming template structure is arranged at the upper end of an outer formwork frame body, and includes: A plurality of comb-shaped templates installed along the length direction of the outer formwork frame body; each comb-shaped template includes a comb-shaped plate, a bottom plate arranged at the lower end of the comb-shaped plate and connected to the outer formwork frame body, and a positioning plate arranged at the side end of the comb-shaped plate; A plurality of fixing clamps distributed along the length direction of the outer formwork frame body; each fixing clamp is located between two adjacent comb-shaped templates and fixes the two comb-shaped templates simultaneously; each fixing clamp includes a fixing plate detachably connected to the outer formwork frame body, an upper clamping plate and a lower clamping plate arranged in parallel at one end of the fixing plate away from the outer formwork frame body; a positioning groove for inserting the positioning plate is formed between the upper clamping plate and the lower clamping plate.

[0009] As a further preference of the present invention, the fixing clamp further includes a clamping member; the clamping member includes a fixed rod portion with one end abutted against the upper surface of the outer formwork frame body, and a telescopic cylinder portion with one end passing through the lower clamping plate and acting on the lower surface of the positioning plate.

[0010] As a further preference of the present invention, the fixed rod portion includes a vertical threaded rod; the telescopic cylinder portion includes a cylinder body passing through the lower clamping plate, a flat plate arranged on the outer circumference of the cylinder body at the lower end of the lower clamping plate, a first fastening nut screwed on the vertical threaded rod, located at the lower end of the lower clamping plate and abutted against the flat plate, and a spring arranged between the lower surface of the lower clamping plate and the flat plate; the spring makes the flat plate tend to approach the lower clamping plate.

[0011] As a further preference of the present invention, the fixed rod portion further includes a first extension plate arranged at the lower end of the vertical threaded rod; the telescopic cylinder portion further includes a second extension plate arranged at the upper end of the cylinder body.

[0012] As a further preference of the present invention, the fixing clamp further includes a mounting plate arranged on the fixing plate and located at the lower end of the lower clamping plate, and an opening for the vertical threaded rod to pass through is arranged on the mounting plate; a second fastening nut screwed on the vertical threaded rod and abutted against the upper surface of the mounting plate is provided.

[0013] As a further preference of the present invention, the fixing clamp further includes a positioning member; the positioning member at least includes a side vertical plate that simultaneously acts on the side ends of two adjacent bottom plates.

[0014] As a further preference of the present invention, the positioning member further includes a first cross plate disposed at the upper end of the side vertical plate and extending to the upper end of the mounting plate, and a side opening groove disposed on the first cross plate for passing through the vertical threaded rod; the second fastening nut abuts against the upper surface of the first cross plate.

[0015] As a further preference of the present invention, the fixed clamp further includes an auxiliary member; the auxiliary member includes a second cross plate for inserting into the positioning groove formed between the upper clamping plate and the lower clamping plate, and a bracket disposed at the outer end of the second cross plate located in the positioning groove for supporting the binding steel bars.

[0016] As a further preference of the present invention, the auxiliary member further includes an anti-slip layer disposed on the upper surface of the second cross plate.

[0017] As a further preference of the present invention, a partition is disposed in the middle of the positioning groove formed between the upper clamping plate and the lower clamping plate.

[0018] The beneficial effects of the present invention are as follows: The precast beam and slab forming template structure provided by the present invention simplifies the structure of the split comb template itself, reduces the mold opening cost of the comb template, and at the same time completes the connection between the split comb templates by clamping two comb templates at both ends of the fixed clamp. The clamping connection with small disassembly and assembly difficulty is adopted to replace the existing methods such as bolt connection with large disassembly and assembly difficulty, so that the connection relationship between the two comb templates can be quickly released by removing one fixed clamp, greatly improving the work efficiency.

[0019] When disassembling the comb template of the precast beam and slab forming template structure provided by the present invention, the comb template at any different position can be arbitrarily selected for disassembly, and at the same time, no cooperation between construction workers is required, and a single person can perform the disassembly, greatly reducing the disassembly difficulty.

Detailed implementation mode

[0026] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "inner", "outer", "left", "right", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product of the present invention is usually placed during use, or the orientation or positional relationship commonly understood by those skilled in the art. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the present invention.

[0027] In the description of the present invention, it should also be noted that unless otherwise clearly defined and limited, terms such as "set" and "connect" should be understood in a broad sense. For example, "connect" can be a fixed connection, a detachable connection, or an integral connection: it can be a mechanical connection or an electrical connection: it can be a direct connection or an indirect connection through an intermediate medium, and can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0028] First of all, it should be pointed out that the precast beam and slab forming template described in the present invention is the top template part for preparing the entire beam body, that is, after the external formwork support (side formwork) is erected, it is installed at the upper end of the external formwork support to assist in the binding of the top reinforcement and is used for the forming of the beam body top plate. The external formwork support is an existing structure, composed of two symmetrical supports. The main body of the support is formed by welding steel frames and I-beams. Power structures such as jacks can be configured at the lower end and side ends, and tracks parallel to the length direction of the support are also configured on the outside, finally realizing the up and down movement and translation along the track of the external formwork support to achieve rapid demoulding. The precast beam and slab forming template provided by the present invention is installed at the upper end of the external formwork support, and its function is to fix the comb-shaped template on the external formwork support to assist in the binding of the top reinforcement.

[0029] The problems existing in the implementation of the existing scenario are that the comb tooth formwork is generally a long board with the same length as the box girder, or several boards with the same length are formed by welding. During formwork erection, due to the long length, multiple workers need to cooperate to complete it, which takes a long time. During formwork removal, it is necessary to first release the connection between the comb tooth formwork and the external formwork frame, then remove the external formwork frame, and finally release the binding relationship between the comb tooth formwork and the exposed steel bars on the top of the formed beam body, so as to remove the entire comb tooth formwork. Moreover, there are also relatively large safety hazards when removing the overweight and overlong comb tooth formwork.

[0030] Based on this, the present invention proposes a precast beam and slab forming formwork structure, and the following are specific embodiments: Refer to Att Figure 1 ~Att Figure 5 As shown, this embodiment provides a precast beam and slab forming formwork structure, which is arranged at the upper end of the external formwork frame 1 and includes: A plurality of comb tooth formworks 2 installed along the length direction of the external formwork frame 1; each comb tooth formwork 2 includes a comb tooth plate 21, a bottom plate 22 arranged at the lower end of the comb tooth plate 21 and connected to the external formwork frame 1, and a positioning plate 23 arranged at the side end of the comb tooth plate 21. Among them, as the name implies, the comb tooth plate 21 refers to a vertical plate with equally spaced teeth formed at the top. The bottom plate 22 at the lower end of the comb tooth plate 21 is used for supporting on the upper surface of the external formwork frame 1; the positioning plate 23 is located at the middle side end of the comb tooth plate 21, is parallel to the bottom plate 22 and has a length greater than that of the bottom plate 22, and is used for connecting with the following fixing fixture 3.

[0031] A plurality of fixing fixtures 3 distributed along the length direction of the external formwork frame 1; each fixing fixture 3 is located between two adjacent comb tooth formworks 2 and fixes the two comb tooth formworks 2 at the same time; each fixing fixture 3 includes a fixing plate 31 detachably connected to the external formwork frame 1, an upper clamping plate 32 and a lower clamping plate 33 arranged parallel to each other at one end of the fixing plate 31 away from the external formwork frame 1; a positioning groove for inserting the positioning plate 23 is formed between the upper clamping plate 32 and the lower clamping plate 33. Among them, the fixing plate 31 is used to penetrate between the two I-beams with opposite openings of the external formwork frame 1 for connecting with the external formwork frame 1; a plurality of spaced threaded holes can be arranged on the fixing plate 31, and fixing holes matching the threaded holes also need to be arranged on the external formwork frame 1. First, adjust the position of the fixing plate 31 so that the appropriate threaded holes are aligned with the fixing holes, and then complete the fixed connection between the fixing plate 31 and the external formwork frame 1 through bolts. The upper clamping plate 32 and the lower clamping plate 33 have the same specifications, and the distance between the two is greater than or equal to the plate thickness of the positioning plate 23 to complete the clamping of the positioning plate 23. In order to avoid the positioning plate 23 from shaking, it is necessary to ensure that the depth of the positioning plate 23 entering the positioning groove accounts for more than 1 / 2 of the length of the positioning plate 23.

[0032] The functions that the above structure can basically achieve are as follows: During installation, the fixed fixture 3 is installed on the outer mold frame body 1 at a fixed interval along the length direction of the outer mold frame body 1. The position of the fixed fixture 3 is the position where the two comb tooth templates 2 are connected. Taking one comb tooth template 2 as an example, the bottom plate 22 is placed on the upper surface of the outer mold frame body 1, and the positioning plate 23 is inserted into the positioning groove formed between the upper clamping plate 32 and the lower clamping plate 33. The two clamping plates fix the positioning plate 23. Through the two connection methods of the abutment between the bottom plate 22 and the outer mold frame body 1 and the engagement connection between the positioning plate 23 and the fixed fixture 3, the comb tooth template 2 is fixed simultaneously from the up-down and left-right directions, completing the fixation of the comb tooth template 2. The two adjacent comb tooth templates 2 abut against each other in the positioning groove, limiting their positions in the length direction (front-back direction) of the outer mold frame body 1, further ensuring the fixation effect of the comb tooth template 2 and improving the connection strength between the two comb tooth templates 2. During disassembly, only the connection between the outer mold frame body 1 and the fixed fixture 3 needs to be released, and then the fixed fixture 3 can be translated along the left-right direction until the two comb tooth templates 2 fixed in the positioning groove are disengaged from the fixed fixture 3. When the fixed fixtures 3 at both ends of the comb tooth template 2 are disassembled, the comb tooth template 2 can be removed.

[0033] The advantages of the above structure are as follows: First, by replacing the integral comb tooth template with a split comb tooth template, the split comb tooth template is shorter in length, lighter in weight, and the required number of workers is also reduced, which helps to improve work efficiency. Second, by clamping the split comb tooth template with the fixed fixture, the connection relationship between the fixed fixture and the comb tooth template can be quickly released, greatly reducing the disassembly difficulty and improving work efficiency.

[0034] As some preferred embodiments, the fixed fixture 3 further includes a clamping member 34; the clamping member 34 includes a fixed rod portion with one end abutting against the upper surface of the outer mold frame body 1 and a telescopic cylinder portion with one end passing through the lower clamping plate 33 and acting on the lower surface of the positioning plate 23. Among them, the telescopic cylinder portion can be connected to the fixed rod portion by a threaded connection method, and the telescopic cylinder portion has the function of adjusting the height position on the fixed rod portion. The telescopic cylinder portion passes through the lower clamping plate 33 and enters the positioning groove, and tightly abuts against the positioning plate 23, thereby further clamping the positioning plate 23 and improving the stability of the positioning plate 23 in the positioning groove, thus improving the fastening effect of the fixed fixture 3 on the comb tooth template 2.

[0035] As some preferred embodiments, the fixed rod portion includes a vertical threaded rod 341; the telescopic cylinder portion includes a cylinder body 342 passing through the lower clamping plate 33, a flat plate 343 provided on the outer periphery of the cylinder body 342 at the lower end of the lower clamping plate 33, a first fastening nut 344 screwed on the vertical threaded rod 341, located at the lower end of the lower clamping plate 33, and abutting against the lower side surface of the flat plate 343, and a spring 345 provided between the lower surface of the lower clamping plate 33 and the flat plate 343; the spring 345 causes the flat plate 343 to tend to approach the lower clamping plate 33. Wherein, the cylinder body 342 is sleeved outside the vertical threaded rod 341, and the first fastening nut 344 is used to limit the height position of the flat plate 343 on the vertical threaded rod 341; the spring 345 is defined as a tension spring, so as to pull the flat plate 343 close to the lower surface of the lower clamping plate 33, and the cylinder body 342 fixedly connected to the flat plate 343 further penetrates into the positioning groove from bottom to top under the action of the flat plate 343, so that the upper end of the cylinder body 342 tightly abuts against the positioning plate 23, strengthening the fastening effect on the positioning plate 23; at the same time, since the spring 345 has a deformation function, the setting of the spring 345 reduces the difficulty of the positioning plate 23 entering the positioning groove, which is helpful for convenient implementation during construction.

[0036] As some preferred embodiments, the fixed rod portion further includes a first extension plate 346 provided at the lower end of the vertical threaded rod 341; the telescopic cylinder portion further includes a second extension plate 347 provided at the upper end of the cylinder body 342. Wherein, the first extension plate 346 and the second extension plate 347 are used to respectively increase the contact area between the vertical threaded rod 341 and the upper surface of the outer mold frame body 1, and the contact area between the cylinder body 342 and the lower surface of the positioning plate 23, so as to improve the overall fixing effect of the clamping member 34.

[0037] As some preferred embodiments, the fixed clamp 3 further includes a mounting plate 35 provided on the fixing plate 31 and located at the lower end of the lower clamping plate 33, and the mounting plate 35 is provided with an opening through which the vertical threaded rod 341 passes; a second fastening nut 364 is screwed on the vertical threaded rod 341 and abuts against the upper surface of the mounting plate 35. Wherein, the mounting plate 35 is used to improve the stability of the lower end of the vertical threaded rod 341, ensure the verticality of the vertical threaded rod 341, and prevent the overall fixed clamp 3 from being deflected, and finally ensure that the installation position of the comb-shaped template 2 is accurately positioned and has good stability.

[0038] As some preferred embodiments, the fixed fixture 3 further includes a positioning member 36; the positioning member 36 at least includes a side vertical plate 361 that simultaneously acts on the side ends of two adjacent bottom plates 22. The side vertical plate 361 that is simultaneously in contact with the side ends of the bottom plates 22 of the two comb templates 2 can correct the positions of the two comb templates 2 in the positioning slots, making their installation depths consistent, thereby ensuring accurate positioning when the two comb templates 2 are spliced, ensuring the overall integrity and smoothness, and helping to improve the forming effect of the top template.

[0039] As some preferred embodiments, the positioning member 36 further includes a first horizontal plate 362 provided at the upper end of the side vertical plate 361 and extending to the upper end of the mounting plate 35, and a side opening groove 363 provided on the first horizontal plate 362 for passing through the vertical threaded rod 341; the second fastening nut 364 abuts against the upper surface of the first horizontal plate 362. Among them, the side opening groove 363 is a U-shaped groove, and the opening diameter of the groove is smaller than the outer diameter of the second fastening nut 364. The first horizontal plate 362 is fixed by pressing the second fastening nut 364, thereby ensuring that the side vertical plate 361 is firmly fixed after being adjusted to a proper position. Preferably, a gasket 365 sleeved on the vertical threaded rod 341 is further provided between the second fastening nut 364 and the upper surface of the first horizontal plate 362 to reduce the wear between the two.

[0040] As some preferred embodiments, the fixed fixture 3 further includes an auxiliary member 37; the auxiliary member 37 includes a second horizontal plate 371 for inserting into the positioning slot formed between the upper clamping plate 32 and the lower clamping plate 33, a bracket 372 provided at the outer end of the second horizontal plate 371 located in the positioning slot for supporting the binding steel bar a, and an anti-slip layer 373 provided on the upper surface of the second horizontal plate 371. Among them, the second horizontal plate 371 can further improve the fastening effect on the positioning plate 23 in the positioning slot and prevent the comb template 2 from shifting; at the same time, the positioning plate 23 reacts on the second horizontal plate 371, so that the second horizontal plate 371 is fixed. Therefore, the bracket 372 connected to the second horizontal plate 371 can serve as a support platform for carrying the binding steel bar a, thereby achieving the effect of assisting in fixing the binding steel bar a. The binding steel bar a is mainly bound and connected with the top plate transverse horizontal bar b placed in the tooth-shaped gap on the comb template 2; the anti-slip layer 373 can be made of common materials such as rubber. The structures of the binding steel bar a and the top plate transverse horizontal bar b and how to bind and connect them are all prior arts, so they will not be described in detail in this embodiment.

[0041] As some preferred embodiments, a partition 38 is provided in the middle of the positioning slot formed between the upper clamping plate 32 and the lower clamping plate 33. Among them, the partition 38 is centrally provided, mainly for positioning the depths of the two comb templates 2 entering the positioning slot in the front-rear direction to make them consistent, so as to ensure that the fixed fixture 3 has a comparable fastening degree for the two comb templates 2.

[0042] The present invention also provides a method for building a precast beam and slab forming template, which specifically includes the following steps: (1) Install two symmetrical outer formwork frameworks; (2) Design the installation spacing of the fixing clamps according to the length of the outer formwork framework and the length of a single comb-shaped template, and install a plurality of fixing clamps on the outer formwork framework according to the installation spacing; (3) One fixing clamp corresponds to the splicing position of two comb-shaped templates. After the side ends of the two comb-shaped templates are abutted, they are fixed by the fixing clamps; (4) After all the comb-shaped templates are installed, lay the top plate transverse horizontal bars on the comb-shaped templates, and tie the ends of all the top plate transverse horizontal bars located on the same outer formwork framework to the same binding steel bar; (5) After the pouring is completed, first release the connection between the fixing clamp and the outer formwork framework, then remove the outer formwork framework, then release the connection between the fixing clamp and the comb-shaped template, and then remove the fixing clamp; (6) After the fixing clamps at both ends of a comb-shaped template are removed, the comb-shaped template can be removed and recycled.

[0043] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Those skilled in the art of the present invention can make various modifications or supplements to the described specific embodiments or use similar methods to replace them, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
