Description

Technical Field

[0001] The invention belongs to the technical field of rapid mold assembly, and in particular relates to a device for rapid on-site assembly of a prefabricated concrete part mold. Background Art

[0002] Stairs are components used for vertical transportation between floors in buildings. They are used for transportation between floors and when there is a large height difference. Although high-rise buildings use elevators as the main vertical transportation tool, they still need to retain stairs for escape in case of fire. Among them, stairs include components such as stair sections and platforms (resting platforms) of continuous steps. Usually, the cast-in-place reinforced concrete stairs used in housing construction projects are stair sections, platforms, ladder beams, etc. cast on site as a whole. They have good integrity, high rigidity, and strong earthquake resistance. However, during the construction process, a series of tedious processes such as installing rest platforms, installing ladder steps, welding, and grouting must be experienced. The construction efficiency is low, and it is very easy to have quality problems such as loose joints of concrete formwork, uneven step surfaces, missing corners and edges, and oversized dimensions, which bring a series of troubles to the subsequent decoration construction and acceptance.

[0003] Therefore, with the development of technology, prefabricated stairs dominated by steel molds have emerged. The stairs are prefabricated in a prefabrication factory or on-site, and then hoisted on-site to the stairwell. Prefabricated stairs are superior to cast-in-place stairs in terms of environmental protection, low carbon and finished product quality. However, prefabricated stairs dominated by steel molds are limited by the heavy weight of the steel molds. Both installation and disassembly require the assistance of mechanical equipment, and the installation efficiency is low. It is impossible to effectively realize the rapid connection between molds. Therefore, a concrete prefabricated mold on-site rapid assembly device is proposed. Summary of the invention

The difference is that the upper positioning column 233 is located on the bottom surface of the upper connecting block 231, so that the upper positioning column 233 and the lower positioning column 223 are arranged opposite to each other. Since the locking assembly 3 is respectively arranged on the upper locking block 234 and the lower locking block 224, when the locking assembly 3 completes the bite-locking connection with the connecting assembly 400, the first mold 1 and the second mold 2 can complete the locking connection, and when the concrete pouring is completed, by removing the upper connecting block 231 from the upper fixing block 23, and then using tools to create a gap between the first mold 1, the second mold 2 and the concrete precast part, then using lifting equipment to lift the stair precast part from above the first mold 1 and the second mold 2, the lower locking block 224 connected by plugging can be separated from the lower connecting block 221 by itself, so that the connecting assembly 400, the locking assembly 3 and the stair precast part form a whole.

Therefore, when the stair prefabricated parts are installed, the upper positioning holes 235 and the lower positioning holes 225 can be conveniently used to install and connect the stair prefabricated parts.

[0024] Example 6: Reference Fig.10 , Fig.11 , Fig.12 , Fig.13 , a concrete prefabricated part mold on-site rapid assembly device, which is basically the same as embodiments 4 and 5, and further, the lock assembly 3 includes a first connecting groove 227 respectively opened in the lower locking block 224 and the upper locking block 234, and the front and back surfaces of the lower locking block 224 are respectively provided with a first slide groove 228 and an avoidance groove 226, and the avoidance groove 226 is used to avoid the latch on the bottom plate 12, and the bottom surface of the upper locking block 234 is provided with a second slide groove 238, and the inner walls on both sides of the first connecting groove 227 are A first side groove 31 is provided, a chamfered groove 32 is provided on the first side groove 31, an elastic steel sheet 33 is fixedly connected in the first side groove 31, and a first elastic abutment plate 34 is fixedly connected to the bottom wall of the first connecting groove 227.

When the locking block 4 is located between the first elastic resistance plate 34 and the elastic steel sheet 33, the side wall of the first side groove 31 and the chamfered groove 32 corresponding to the first connecting groove 227 is perpendicular to the first connecting groove 227, thereby preventing the locking block 4 from detaching from the first connecting groove 227, thereby realizing the bite connection between the locking assembly 3 and the connecting assembly 400.

[0025] Example 7: Reference Fig.10 , Fig.11 , Fig.12 , Fig.14 , a concrete prefabricated part mold on-site rapid assembly device, which is basically the same as embodiments 4 and 5, and further, the locking assembly 3 includes a second connecting groove 237 respectively opened in the lower locking block 224 and the upper locking block 234, the front and back surfaces of the lower locking block 224 are respectively provided with a first slide groove 228 and an avoidance groove 226, the bottom surface of the upper locking block 234 is provided with a second slide groove 238, and the inner walls on both sides of the second connecting groove 237 are provided with second side grooves 311, the second side grooves 311, and the second side grooves 311. 1 is slidably connected to a side slider 312 with a clamping block 313 at one end, the side slider 312 is connected to the bottom wall of the second side groove 311 through a spring 314, and a second elastic contact plate 315 is fixedly connected to the bottom wall of the second connecting groove 237. When the lower locking block 224 and the upper locking block 234 approach the locking block 4 on the connecting rod 41, the locking block 4 passes over the side slider 312 and enters the second connecting groove 237 between the second elastic contact plate 315 and the side slider 312, so that the locking assembly 3 bites the connecting rod 41; When the first mold 1 approaches the second mold 2, the locking blocks 4 at both ends of the connecting rod 41 will enter the second connecting grooves 237 of the lower locking block 224 and the upper locking block 234 respectively, and the locking blocks 4 will push the side sliders 312 to slide into the second side grooves 311 and squeeze the springs 314, and then the locking blocks 4 will pass over the symmetrically arranged side sliders 312, so that the locking blocks 4 are located between the second elastic contact plates 315 and the side sliders 312; Since the side slide block 312 is arranged in the second side groove 311 for tilted sliding, the locking block 4 is difficult to be separated from the second connection groove 237, so that the first mold 1 and the second mold 2 can be connected more stably; It should be noted that the end of the side sliding block 312 is limited and slidable in the second side groove 311 by the clamping block 313 .
