Description
Technical Field
The utility model belongs to the technical field of templates for concrete pouring, and particularly relates to a variable outer template structure of a prefabricated hollow slab.
Background
The prefabricated hollow slab refers to a hollow slab body which is prefabricated in advance before site construction. The outer form construction, however, serves to define the outer contour of the hollow slab, independent of the internal hollow structure.
On the other hand, the outer form construction can be divided mainly into 3 parts, namely 2 side plates and 1 bottom plate. The three are generally matched with a hydraulic oil cylinder to ensure the effective die assembly and die disassembly operations before and after pouring the hollow slab.
In addition, the main dimensional parameters for the hollow slab itself are the span and the cross-sectional shape. The former depends on the longitudinal length of the outer form construction, while the latter depends primarily on the specific shape of the side panels. If the side plate is adjustable and changeable, various hollow plate products with different specific shapes can be finally constructed so as to meet different construction requirements.
The patent publication No. CN209699441U, publication No. 2019.11.29, discloses an adjustable outer formwork for prefabricating a bridge hollow slab, wherein a wing plate side formwork of the outer formwork is arranged to be of a movable structure, a horizontal adjusting plate which is horizontally arranged and is vertical to the wing plate side formwork is welded on the outer wall of the wing plate side formwork, a horizontal chute which is horizontally arranged is arranged on the horizontal adjusting plate, a vertical adjusting plate is welded on a supporting upright rod of the outer formwork, a vertical chute is arranged on the vertical adjusting plate, the horizontal chute and the vertical chute are crossed, and an adjusting bolt is inserted at the crossing.
The general structural principle of the adjustable outer die plate in the patent of the utility model is as follows: the side templates are movable, and after the transverse adjusting plates are pushed inwards, the left side template and the right side template can be folded, so that the hollow plate can obtain smaller top width, and the prefabricating effect of the hollow plate is more flexible and comprehensive.
However, the adjustable outer template has at least the following 2 defects in the actual use process, in other words, the technical problem to be solved by the utility model is solved.
1. The bending angle of the bottom template is unchanged, so that the inclination angle of the inclined lower surface of the hollow plate is not adjustable, and the application range of the hollow plate is greatly reduced.
2. The bottom formwork lacks an external fixing structure with enough supporting strength, so that the risk of collapse of the formwork is not small after concrete pouring.
In view of the foregoing, there is a need for a flexible, adjustable and relatively stable outer form construction for use with hollow core slabs.

Detailed Description
The following description is of the preferred embodiments of the utility model and is not intended to limit the scope of the utility model.
As shown in fig. 1 to 7, a variable outer formwork structure of a hollow slab comprises a hinge frame unit 1 for installing a sliding block 10 and a hydraulic cylinder 11, two-section hinge plate units 2 arranged on the hinge frame unit 1, and an inner lining plate unit 3 arranged on the two-section hinge plate units 2.
In this embodiment, the complete outer formwork structure includes 2 side plate structures and 1 bottom plate structure, the side plate structures are a plurality of paired hinged frame units 1 and two-section hinged plate units 2, and the strip-shaped inner lining plate units 3 are added, and the inner lining plate units 3 are formed by splicing a plurality of pieces Bao Gangban, so that the span of the prefabricated hollow slab is flexible and selectable.
The floor structure described above, including the already self-contained lift cylinder structure of the floor 12, ultimately constitutes a total of 3 faces of the enclosed sides and bottom edge for the entire outer form construction, leaving the top face for pouring of poured concrete.
The two-section hinge plate unit 2 rotates in the hinge plate unit, namely, the hinge plate unit is used for providing flexible and variable side surface shape for the hollow plate a, and the hinge frame body unit 1 is used for matching the two-section hinge plate unit 2 after hinged rotation, so that the hinge plate unit can be supported and fixed in a stable enough way when the hinge plate unit rotates randomly within a certain range.
Finally, the lining board unit 3 is only required to be vertically stretched if being a single sheet steel, and if being formed by splicing a plurality of boards in the longitudinal direction, namely the span direction, the spliced position needs to ensure enough tightness, and a large amount of concrete is prevented from leaking out of the gap position.
The hinge frame unit 1 includes an outer vertical plate 101, an upper hinge plate portion 102 and a lower mounting plate portion 103 provided on the outer vertical plate 101, and a lower mounting hole 104 provided on the outer vertical plate 101 for connecting the slider 10.
In the present embodiment, the "outer side" word of the outer side riser 101 means that it is far away from the lining panel unit 3, i.e. the lining panel unit 3 is the innermost side of the outer formwork construction.
In addition, the lower mounting plate 103 is fixedly connected with the two-section hinge plate units 2, and the upper hinge plate 102 can be adjusted in length and angle, so that the two-section hinge plate units 2 after rotation are still effectively supported and fixed.
The upper hinge plate part 102 includes a fixed orifice plate 102a provided on the outer side vertical plate 101, a rotating rod 102b hinge-coupled to the fixed orifice plate 102a, an internally threaded tube 102c provided on the rotating rod 102b, and an adjusting screw 102d provided on the internally threaded tube 102c and used for connecting the two-stage hinge plate units 2.
In this embodiment, one end of the rotating rod 102b is also provided with an opening for hinging the fixed orifice plate 102a, and the other end of the rotating rod is used for screwing or plugging the internal threaded tube 102c, so that the total length of the rotating rod 102b, the internal threaded tube 102c, and the adjusting screw 102d is adjustable.
In addition, before the two-section hinge plate unit 2 rotates to adjust itself, the adjusting screw 102d is disconnected with the hinge plate unit, and connection is established after the former rotation adjustment is completed, and the connection mode can be welding, clamping or binding.
The lower mounting plate portion 103 includes a lower fixing plate 103a provided on the outer side vertical plate 101 for connecting the two-stage hinge plate units 2, and an inner side hole plate 103b provided on a lower surface of the lower fixing plate 103a for connecting the slider 10.
In this embodiment, the inner hole plate 103b is matched with the lower mounting hole 104, and corresponds to the inner connecting position and the outer connecting position of the slider 10, so as to ensure that the hinge bracket unit 1 has a stable sliding base, and avoid that the weight of the hinge bracket unit is excessively pressed on the hydraulic cylinder 11. In other words, the articulated frame unit 1 cannot bend the hydraulic cylinder 11, but can press the hydraulic cylinder 11 only.
The lower mounting plate portion 103 further includes a protruding round bar 103c provided on a side surface of the lower fixing plate 103a and used for connecting the hydraulic cylinder 11.
In this embodiment, the single lower fixing plate 103a is provided with the left and right protruding round bars 103c, so that 1 hinge bracket unit 1 can correspond to 2 hydraulic cylinders 11, and the mold clamping driving force of the outer mold plate structure is ensured to be sufficient.
Furthermore, the hydraulic cylinder 11 is provided with a mounting ring for the socket-connection of the protruding round bar 103c in a manner known in the art.
The two-piece hinge plate unit 2 includes an upper plate 201 provided on the adjustment screw 102d, and a lower bent plate 202 hinge-mounted on the upper plate 201.
In this embodiment, the lower bending plate 202 has an obtuse angle, and a basic hinging effect is ensured between the lower bending plate and the upper plate 201 by means of respective openings and externally adding a hinging shaft. The two can be simply staggered, or one can be thicker and the other can be thinner, and the latter can be inserted into the slot of the former.
The two-piece hinge plate unit 2 further includes a longitudinal plate 203 provided on the upper plate 201 or lower bent plate 202 for mounting the interior lining plate unit 3.
In this embodiment, the longitudinal plate 203 is perpendicular to the vertical plane formed by the upper plate 201 and the lower bending plate 202, and is horizontal, and is disposed only on the upper plate 201 and on the plate body of the lower bending plate 202, which is far from the hinge end.
Therefore, the longitudinal plates 203 are divided into two groups, namely, an upper group of the lowest longitudinal plate 203 of the longitudinal plates 203 and a lower group of the uppermost longitudinal plate 203 of the longitudinal plates 203, which are bending portions of the lining plate unit 3.
Also, between 2 of the two-stage hinge plate units 2 adjacent to each other in the longitudinal direction, i.e., in the span direction, the longitudinal plates 203 thereof need to be as close as possible, and may even be joined end to end, and staggered up and down after being too long, in order to provide a larger effective support area on the interior lining plate unit 3 as much as possible.
The longitudinal panels 203 are disposed on at least 2 of the upper panels 201 or lower bend panels 202.
In this embodiment, the longitudinal plates 203 on the two-section hinge plate units 2 are simultaneously connected with another adjacent two-section hinge plate unit 2, so that all the two-section hinge plate units 2 can be "integrated" to form a supporting frame structure with stronger integrity.
The lining board unit 3 includes lining sheets 301 provided on all the longitudinal plates 203 and bent into 3 segments, and a rail 302 provided on the lining sheets 301 and indicating the maximum casting amount of concrete.
In this embodiment, all of the lining sheets 301 in the longitudinal direction need to be joined end to end in order and sufficiently sealed and reinforced at the joint.
The cross bar 302 has a triangular vertical cross-sectional shape.
In this embodiment, the upper limit of concrete pouring of the hollow slab a is the protruding edge of the triangular prism-shaped cross bar 302, at this time, the cross bar 302 may replace the original right-angle edge of the hollow slab a with 2 obtuse-angle edges, which are less likely to be damaged, and this is the second effect of the cross bar 302, one of which is the height limiting indication described above.
The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various modifications may be made within the knowledge of those skilled in the art without departing from the spirit of the present utility model. These are all non-inventive modifications which are intended to be protected by the patent laws within the scope of the appended claims.
