Description

Technical Field

[0001] The utility model relates to a cast-in-place concrete vertical plate, in particular to an inner support rod mechanism of a casting template of a concrete vertical plate in which only a single row of steel bars is pre-embedded. Background Art

[0002] Concrete vertical slabs with a single row of steel bars embedded in the slab are a common form of cast-in-place concrete components in the main structure of buildings. They are widely used in components such as balcony railings, bay window side panels, and roof parapets. When casting concrete vertical slabs, in order to ensure the accuracy of the cross-sectional dimensions of the concrete vertical slabs and avoid slab thickness errors, internal support rods are usually set in the two formworks for pouring the concrete vertical slabs to ensure that the spacing between the two formworks remains unchanged. Traditional cast-in-place concrete walls are all equipped with double rows of embedded steel bars, and the internal support rods between the two formworks can be stably fixed between the two rows of embedded steel bars. However, for cast-in-place concrete slabs with only a single row of steel bars in the slab, there is a problem that the internal support rods cannot be stably fixed on the single row of embedded steel bars. One method is to use wooden strips as inner support rods, first fix the inner support rod wooden strips on one side of the vertical formwork with nails, and then connect the other end of the inner support rod wooden strips to the vertical formwork on the other side, so as to fix the distance between the two vertical formworks. The advantage of this method is that the formwork support is relatively convenient, but there is a defect that the quality of the vertical slab concrete structure is poor. Since the vertical slabs are all exterior wall components, according to the requirements of building specifications, the holes in the exterior wall must be sealed and waterproofed. For the vertical slabs of the above-mentioned construction method, after the concrete solidifies, the inner support rod wooden strips in the vertical slabs must be taken out and sealed and waterproofed. Not only is the later construction complicated and the construction cost high, but the sealing holes of the inner support rod wooden strips will also have a greater risk of water leakage.

[0020] A method for supporting inner support rods in a concrete casting template of a single-row reinforcement vertical plate is provided. First, the embedded single-row reinforcement of the precast concrete vertical plate is constructed, and transverse reinforcement 24 and vertical reinforcement 30 are arranged in the embedded single-row reinforcement. The steps of setting up the concrete casting template of the precast single-row reinforcement vertical plate are as follows:

[0021] The first step is to make the inner support rod. The specific steps are as follows: according to the thickness of the precast concrete vertical plate, a horizontal support rod 1 is made, and a left conical support foot block 4 and a right conical support foot block 13 are made; a left conical head 2 is fixedly provided at the left end of the horizontal support rod 1, and a right conical head 11 is fixedly provided at the right end of the horizontal support rod 1, that is, the horizontal support rod 1 is in the shape of a dumbbell, with a thin rod in the middle and large conical heads at both ends, a left center screw hole 3 is provided on the left end facade of the left conical head 2, the left conical support foot block 4 is screwed into the left center screw hole 3, a right center screw hole 12 is provided on the right end facade of the right conical head 11, and the right conical support foot block 13 is screwed into the right center screw hole 12. The reason why the two conical support foot blocks are designed in combination with the horizontal support rod 1 is to realize that the length of the horizontal support rod 1 can be adjusted in the horizontal direction, so that it can be reliably connected with the two vertical The top connection of the template; the first reinforcing rib plate 7, the second reinforcing rib plate 8, the third reinforcing rib plate 10 and the fourth reinforcing rib plate 9 are arranged at equal intervals on the horizontal support rod 1 between the left conical head 2 and the right conical head 11. The four reinforcing rib plates are distributed in a cross shape on the horizontal support rod 1, which plays a role in strengthening the strength of the horizontal support rod 1; a first trapezoidal sliding block 18 is movably embedded between the first reinforcing rib plate 7 and the fourth reinforcing rib plate 9, a transverse steel bar clamping ring seat 20 is connected to the outer end of the first trapezoidal sliding block 18, and a transverse steel bar clamping ring 23 is connected to the transverse steel bar clamping ring seat 20; a second trapezoidal sliding block 27 is movably embedded between the third reinforcing rib plate 10 and the fourth reinforcing rib plate 9, a vertical steel bar clamping ring seat 28 is connected to the outer end of the second trapezoidal sliding block 27, and a vertical steel bar clamping ring 29 is connected to the vertical steel bar clamping ring seat 28;

[0022] The second step is to horizontally support the horizontal brace 1 on the embedded single-row reinforcement, clamp the transverse reinforcement clamping ring 23 on the transverse reinforcement 24 of the embedded single-row reinforcement of the vertical plate, and clamp the vertical reinforcement clamping ring 29 on the vertical reinforcement 30 of the embedded single-row reinforcement of the vertical plate. The horizontal brace 1 is supported on the embedded single-row reinforcement by the transverse reinforcement clamping ring 23 and the vertical reinforcement clamping ring seat 28, respectively, so as to achieve a stable connection and fixation between the horizontal brace 1 and the embedded single-row reinforcement;

[0023] The third step is to set up the left side formwork 31 and the right side formwork 33 of the precast concrete vertical slab, lay out the left wooden slat 32 on the outer side of the left side formwork 31, and lay out the right wooden slat 34 on the outer side of the right side formwork 33, and use the tension bolts 35 to fix the two formworks together, so that the horizontal support rod 1, the left conical support foot block 4 and the right conical support foot block 13 are supported between the left side formwork 31 and the right side formwork 33, and the concrete is poured. The left side vertical formwork 31 for soil pouring, the left conical support block 4, the horizontal support rod 1, the right conical support block 13, the right side vertical formwork 33 for concrete pouring and the tension bolts 35 form a stable horizontal force system, which ensures the reliability and stability of the vertical slab concrete pouring formwork system. At the same time, the adjustable length of the left conical support block 4, the horizontal support rod 1 and the right conical support block 13 ensures the distance between the left side vertical formwork 31 for concrete pouring and the right side vertical formwork 33 for concrete pouring, thereby achieving the consistency of the thickness of the vertical slab cross section.

[0024] Due to the difference in the positions of the transverse reinforcement 24 and the vertical reinforcement 30 set in the embedded single-row reinforcement, when the horizontal support rod 1 is combined with the embedded single-row reinforcement, the positions of the two clamping rings need to be dynamically adjusted. Therefore, a transverse reinforcement clamping ring seat screw connection screw hole 19 is provided on the outer end of the first trapezoidal sliding block 18, and the transverse reinforcement clamping ring seat 20 is screwed into the transverse reinforcement clamping ring seat screw connection screw hole 19. By rotating the transverse reinforcement clamping ring seat 20, the spacing between the transverse reinforcement clamping ring 23 and the transverse reinforcement 24 is adjusted to achieve the clamping connection between the two. A T-shaped groove seat 21 is arranged on the top, and a T-shaped connector 22 is arranged on the transverse steel bar clamp 23. The T-shaped connector 22 of the transverse steel bar clamp 23 is movably sleeved in the T-shaped groove seat 21, thereby realizing the rotation of the transverse steel bar clamp 23. By rotating the transverse steel bar clamp 23, the transverse steel bar clamp 23 is adapted to the arrangement direction of the transverse steel bar 24; by rotating the vertical steel bar clamp 29, the matching direction of the vertical steel bar clamp seat 28 and the vertical steel bar clamp 29 is adjusted, so that the vertical steel bar clamp 29 is adapted to the arrangement direction of the vertical steel bar 30; thereby realizing quick installation on site.

[0025] Due to the difference in the positions of the transverse steel bars 24 and the vertical steel bars 30 set in the embedded single-row reinforcement, in order to combine the two steel bar clamps on the horizontal support rod 1 with the transverse steel bars 24 and the vertical steel bars 30 set in the embedded single-row reinforcement on site, the first trapezoidal sliding block 18 and the second trapezoidal sliding block 27 are designed to be movable, so as to facilitate the installation of the horizontal support rod 1 on the embedded single-row reinforcement on site; the specific measures are: a groove slide rail 25 is provided on the first reinforcing rib plate 7, and a protrusion 26 is provided on the first trapezoidal sliding block 18, and the protrusion 26 is movably arranged in the groove slide rail 25; the first trapezoidal sliding block 18 realizes the sliding of the first trapezoidal sliding block 18 between the first reinforcing rib plate 7 and the fourth reinforcing rib plate 9 through the cooperation of the protrusion 26 and the groove slide rail 25, and adjusts the transverse steel bar clamp seat 20 to a position where it can be connected with the transverse steel bar clamp 23; generally, two protrusions 26 are provided on the first trapezoidal sliding block 18, so that the first trapezoidal sliding block 18 and the two reinforcing rib plates are reliably and movably connected together.

[0026] A left center groove 5 is provided at the center of the left end elevation of the left conical support foot block 4, a left-shaped left rotating plate 6 is provided in the left center groove 5, a right center groove 14 is provided at the center of the right end elevation of the right conical support foot block 13, a right-shaped right rotating plate 15 is provided in the right center groove 14; a left water stop ring 16 is provided on the left conical head 2, and a right water stop ring 17 is provided on the right conical head 11; after the formwork system of the precast concrete vertical slab is constructed, concrete is poured, and when the poured concrete is finally set, the left water stop ring 16 is first removed. The side formwork 31 and the concrete pouring right side formwork 33 are then removed from the cast vertical wall by rotating the I-shaped left rotating plate 6, and the right conical support block 13 is removed from the cast vertical wall by rotating the I-shaped right rotating plate 15. They can be reused. Finally, the groove formed after removing the left conical support block 4 and the groove formed after removing the right conical support block 13 are sealed. Since water stop rings are provided at both ends of the horizontal support rod 1, the sealed grooves have a good anti-water seepage effect.
