Description

Technical Field

[0001] This utility model relates to the field of prestressed composite slab mold technology, specifically a quick-release new type of prestressed composite slab mold. Background Technology

[0002] Prestressed composite slab molds play a crucial role in the production of precast building components, and the design of their rebar slots directly affects the mold's sealing performance and production efficiency. In existing technologies, the rebar slots are typically sealed by inserting individual sealing components one by one. This design has significant drawbacks: firstly, during mold assembly, operators need to individually align and insert each sealing component into the rebar slot, a tedious and time-consuming process; secondly, during mold disassembly, each sealing component must be removed individually, which is not only inefficient but also prone to damage or loss due to improper operation. Therefore, a new mold structure capable of quickly sealing and removing rebar slots is urgently needed to improve production efficiency and reduce labor intensity. Utility Model Content

[0023] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] like Figure 1-7As shown, this utility model provides a technical solution: a quick-release novel prestressed composite slab mold, comprising a frame composed of four templates 1. Each template 1 is integrally injection molded from plastic material and consists of mutually perpendicular vertical and horizontal parts. The four templates 1 are connected and fixed by bolts 2 at the four corners, forming a rectangular frame structure placed on the processing table of the composite slab. The horizontal parts of the templates 1 are locked and fixed on the processing table by fasteners on the processing table, thus fixing the templates 1 to the processing table of the composite slab. The four corners of the four templates 1 are secured by bolts. 2. Connection and Fixing: Several steel bar slots 3 are provided in the vertical part of the four templates 1, and each steel bar slot 3 is equipped with a sealing block 4. The bottom end of the steel bar slot 3 and the bottom end of the sealing block 4 are semi-circular. Both sides of the sealing block 4 are provided with snap-fit ​​pieces 5. After the sealing block 4 is inserted into the steel bar slot 3, it is fixed by snapping with the side of the steel bar slot 3 through the two snap-fit ​​pieces 5. The same quick-release plate 6 is connected to each adjacent group of sealing blocks 4. Align the reserved steel bar on the outside of the composite plate with the steel bar slot 3 in the vertical part of the template 1, and insert it to ensure that the steel bar is in contact with the steel bar slot 3. The semi-circular bottom of the rebar groove 3 is fully fitted. Then, multiple sealing blocks 4 connected with quick-release plates 6 are taken and aligned with the corresponding number of rebar grooves 3. The entire set of sealing blocks 4 is pressed firmly to ensure that the locking tabs 5 on both sides of the sealing blocks 4 are fully engaged with the sides of the rebar groove 3. It is also checked that the top of the sealing blocks 4 is flush with the top of the vertical part of the template 1. Concrete is poured into the assembled mold. After the concrete reaches the specified strength, the quick-release plates 6 are held and pulled outward to remove multiple sealing blocks 4 at once. After the sealing blocks 4 are inserted into the rebar groove 3, the top of the sealing blocks 4 is flush with the top of the template 1. The top of the vertical part of template 1 is flush, which can prevent the protrusion of the sealing block 4 from affecting the leveling and processing of the composite slab. Several reinforcing plates 7 are provided between the vertical and horizontal parts of template 1 to strengthen the vertical and horizontal parts of template 1. The reinforcing plates 7 are set close to the steel bar groove 3. Several protruding blocks 8 are provided on the inner side of the four templates 1. The setting of several protruding blocks 8 can increase the strength of the mold. The several protruding blocks 8 can form grooves on the side wall of the concrete composite slab, which is beneficial to the bonding performance during the later assembly and pouring of the concrete composite slab.

[0025] The operational steps for this application are as follows:

[0026] Four templates 1 are connected and fixed by bolts 2 at the four corners to form a rectangular frame structure. The frame is placed on the processing table of the composite plate and the horizontal part of the template 1 is fixed by the fasteners on the processing table. The pre-reserved steel bars on the outside of the composite plate are aligned with the steel bar grooves 3 in the vertical part of the template 1 and inserted to ensure that the steel bars are completely in contact with the semi-circular bottom of the groove. Then, multiple sealing blocks 4 connected with quick-release plates 6 are taken and the entire set of sealing blocks 4 is aligned with the corresponding number of steel bar grooves 3. The blocks are pressed down to make the snap-fit ​​pieces 5 on both sides of the sealing blocks 4 completely snap into the sides of the steel bar grooves 3. The top of the sealing blocks 4 is checked to see if it is flush with the top of the vertical part of the template 1.

[0027] Pour concrete into the assembled mold. Once the concrete reaches the specified strength, hold the quick-release plate 6 and pull it outward to remove multiple sealing blocks 4 at once.
