Description

Technical Field

[0001] The utility model relates to the technical field of composite floor slabs, in particular to a casting template for double-T slabs. Background Art

[0002] A composite floor slab is an assembled integral floor slab formed by laminating precast slabs and cast-in-place reinforced concrete layers. The precast slab is not only one of the components of the floor structure, but also a permanent formwork for the cast-in-place reinforced concrete composite layer, and horizontal equipment pipelines can be laid in the cast-in-place composite layer. The composite floor slab has good integrity, high rigidity, can save formwork, and the upper and lower surfaces of the slab are flat, which facilitates decoration of the finish layer. It is suitable for high-rise buildings and large-bay buildings with high requirements on overall rigidity.

[0003] In the prior art, a double-T precast slab is also referred to as a double-T slab for short. Its structure includes a panel A and two rib beams B convexly arranged on the panel. Steel bars are respectively protruded from the bottom of the rib beams B and both ends of the panel. When in use, the panel A faces downward and abuts against a wall or a beam; the rib beams B face upward and combine with the cast-in-place reinforced concrete layer C, and the protruding steel bars are connected with the steel bars in the cast-in-place reinforced concrete layer C (for specific reference Figure 1 shown). At present, when a double-T slab is precast and cast, the rib beams B are usually arranged downward, and the side surfaces of the rib beams B are in direct contact with the formwork. However, after hardening, the side surfaces are relatively smooth and the surface roughness is too small, resulting in poor bonding effect with the cast-in-place reinforced concrete layer C. Furthermore, since the formwork is located below the rib beams B, it is difficult to implant steel bars, form removal is relatively troublesome, and manufacturing is relatively complicated. In addition, current formworks are usually of fixed size, have large weight, the length of the produced double-T slab is always fixed, and it is necessary to re-manufacture the formwork to produce double-T slabs of other sizes. Therefore, there is an urgent need to solve the above problems. Utility Model Content

[0004] In view of the above problems, the utility model provides a casting template for a double-T slab, which has the advantages of simple structure, convenient operation and quick disassembly and assembly, can realize modular production of multi-size double-T slabs, and ensures the bonding strength between the double-T slab and the cast-in-place reinforced concrete layer.

[0005] The utility model achieves the above purpose through the following technical solutions: a casting template for a double-T slab comprises a formwork frame, side plates, rib plates and end plates, wherein the formwork frame is in a shape of a Chinese character '冂', a first fixing plate is respectively arranged at both ends of the formwork frame, and a second fixing plate is arranged on the middle bottom surface of the formwork frame; the side plates are detachably connected with the first fixing plates, and the end plates are detachably connected to both ends of the side plates respectively; the side plates are arranged perpendicular to the formwork frame, and the side plates are arranged parallel to the rib plates; at least one formwork frame is arranged along the extension direction of the side plates; The rib plate is detachably connected to the second fixing plate, and the end portion of the rib plate is detachably connected to the end plate; The outer shape of the end plate matches the cross section of the double-T slab, and a plurality of reinforcement outlet openings are provided on the end plate.

[0006] Further, two side plates are symmetrically arranged, and a first positioning plane is provided on opposite side surfaces of the two side plates, wherein the first positioning plane is adapted to a side surface of a face plate. Under the action of the first positioning plane, the position of the side surface of the face plate is effectively positioned, ensuring that the forming width position of the face plate is correct.

[0007] Further, four rib plates are provided, the rib plates are symmetrically arranged in groups of two, and a second positioning plane is provided on opposite side surfaces of each group of the rib plates, wherein the second positioning plane is adapted to a side surface of a rib beam. Under the action of the second positioning plane, the position of the side surface of the rib beam is effectively positioned, ensuring that the forming width, shape and position of the rib beam are correct.

[0008] Further, first through holes are respectively formed on the first fixing plate and the second fixing plate, and second through holes corresponding to the first through holes are respectively formed on the side plates and the rib plates. It is convenient for detachable connection of the side plates and the rib plates with the mould frame, and facilitates disassembly and assembly of the mould plate.

[0009] Further, studs are provided on the end plate, and third through holes adapted to the studs are respectively formed at end portions of the side plates and the rib plates. It is convenient for detachable connection of the end portions of the side plates and the rib plates with the end plate, and facilitates disassembly and assembly of the mould plate.

[0010] Compared with the prior art, the beneficial effects of the present utility model are as follows: Firstly, the side plates are detachably connected to both sides of the mould frame through first fixing plates, and the rib plates are detachably connected to the middle part of the mould frame through second fixing plates, so as to position the side surfaces of the rib beams and the side surfaces of the face plate, and perform limiting in the forming width direction of the double-T slab; limiting is performed by the end plate in the forming length direction, and the end plate is detachably connected to the rib plates and the side plates respectively. When the length dimension of the double-T slab to be produced needs to be changed, only the relative distance between the two end plates needs to be adjusted, so that the length dimension of the formed double-T slab can be adaptively changed, thereby realizing modular production of multi-size double-T slabs; Secondly, since the mould frame is arranged in a 冂 shape, the rib plates and the second fixing plates are detachably connected to the middle bottom surface of the mould frame, so that the formed rib beams face upward. When steel bars at the rib beam positions are implanted, they can be inserted directly from above, without obstruction from the mould plate, and the steel bars at the end of the face plate can directly pass out through the reinforcement outlet openings, which is very convenient and quick to operate; Thirdly, all components of the entire mould plate are connected through detachable connection structures, which is relatively convenient during mould removal and mould assembling, effectively saving manual operation time and reducing operation difficulty; Fourth, the entire template has fewer components and a relatively simple structure, which can effectively reduce the overall weight while ensuring the overall strength of the template, and is also relatively convenient for transportation and handling. Fifth, since the formed rib beam is on top and the panel is on the bottom, under the action of gravity and the vibrator, the side surface of the rib beam has a large surface roughness after forming, which can provide a large friction force, resulting in a good bonding effect with the cast-in-place reinforced concrete layer C; thus solving the technical problems in the prior art; overall, this utility model has the advantages of simple structure, convenient operation and quick assembly and disassembly, and can realize the modular production of multi-size double T plates, ensuring the bonding strength between the double T plate and the cast-in-place reinforced concrete layer.
