Description

Technical Field

[0001] This invention belongs to the field of precast concrete beam casting, specifically a casting mold for processing precast concrete rib beams. Background Technology

[0002] Floor slabs are one of the main load-bearing structures in building construction. Concrete floor slabs are classified into ribbed floor slabs and flat slabs according to their structural form. Ribbed beams refer to slabs with main or secondary beams acting as ribs beneath them. For example, one-way ribbed floor slabs typically use secondary beams and part of the main beams as ribs, while two-way ribbed floor slabs typically use main beams as ribs. The advantages of cast-in-place reinforced concrete ribbed floor slabs are smaller concrete usage, clear stress distribution, and simpler design. However, the disadvantages are higher construction difficulty, longer construction period, and increased on-site construction time.

[0003] Precast building materials can solve these problems precisely; precast buildings can use reinforced concrete structures, which can effectively improve the stability of buildings compared to brick and tile structures, while reducing the cost of direct casting, shortening the construction period, and custom casting of precast ribs can further shorten the cycle.

[0004] Currently, when using precast concrete casting, it is necessary to customize casting molds according to the size of the precast beams being cast. Most floor slabs are now cast-in-place concrete slabs, which are relatively large systems. This requires a large number of casting molds, and the custom-sized casting molds have a low recycling rate, resulting in a waste of resources. This method is neither economical nor environmentally friendly. In addition, this casting method does not have fixed molds, and the secondary utilization rate of molds is low. The fixing components are mostly simple steel bar hoops, which are not stable. This results in non-standard precast concrete castings, which affects the connection of rib beams in the later stage.

[0005] In summary, the present invention provides a casting mold for processing precast concrete rib beams to solve the above-mentioned problems. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a casting mold for processing precast concrete rib beams, which solves the problems of existing casting molds having customized dimensions, low recycling rates, resulting in resource waste, and being neither economical nor environmentally friendly.

[0007] A casting mold for fabricating precast concrete rib beams includes:

[0008] A mold base assembly includes at least one mold body connected in series, with any two mold bodies being detachably connected. Each mold body has openings at both ends, and a joint sealing strip is provided between the two mold bodies. The top of each mold body is an open structure, and multiple steel strand through holes are provided on the mold body. A reinforcement mechanism is provided on the surface of the open part of the mold body.

[0009] End sealing plate one, wherein the end sealing plate one is disposed at one end of the mold body;

[0010] End sealing plate 2, and end sealing plate 1 are both provided with a blocking plate groove. End blocking plate 1 and end blocking plate 2 are respectively provided in the blocking plate groove. Multiple steel strand through holes are respectively provided on end sealing plate 2 and end sealing plate 1.

[0011] A positioning guide plate is provided on one side of an end sealing plate. A lead screw is vertically connected to the positioning guide plate, and a pressure plate is rotatably connected to one end of the lead screw. Limiting clamping holes are provided on the surface of the positioning guide plate, and multiple anchor clamping plates are respectively provided in the limiting clamping holes.

[0012] A restraint plate is set on one side of the end sealing plate 2. A plurality of positioning steel strands are fixedly connected to one side of the restraint plate. The positioning steel strands pass through the steel strand through holes and are in contact with the anchor clamps.

[0013] Furthermore, the reinforcing mechanism includes multiple slide groove groups, and the slide groove groups are opened on both outer walls of the mold body at the opening. Each slide groove group includes two separate slide grooves, and a card seat slider and a rotating component slider are slidably connected in the slide grooves respectively. A reinforcing rod is rotatably connected to the rotating component slider, and a carding component is fixedly connected to one end of the reinforcing rod.

[0014] Furthermore, positioning rods are fixedly connected to one side of both the mold body and the first end sealing plate, and corresponding positioning holes are opened on the other side of both the second end sealing plate and the mold body.

[0015] Furthermore, sealing protrusions are provided at both ends of the mold body, and the sealing protrusions are inserted into the end sealing grooves.

[0016] Furthermore, end sealing grooves are respectively provided on the side of the end sealing plate one and the end sealing plate two near the mold body, and end sealing strips are provided in the end sealing grooves.

[0017] Furthermore, two end-blocking plates are provided on both sides of the first end-blocking plate, and steel bar through holes are respectively provided on the first end-blocking plate and the second end-blocking plate.

[0018] Furthermore, one end of the lead screw passes through the positioning guide plate and is connected to the positioning guide plate by a thread. The end of the lead screw away from the pressure plate is fixedly connected to a rocker handle. The pressure plate is disposed on the surface of the end sealing plate.

[0019] Furthermore, multiple anchor clamps are movably disposed within the limiting clamping hole. The anchor clamps are arranged in a ring array on the surface of the positioning steel strand. One side wall of each anchor clamp is in contact with the positioning steel strand, and the other side wall is inclined and matches the limiting clamping hole.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. By setting up a modular mold body, the present invention can adjust the length of the prefabricated parts by increasing the number of mold bodies. The modular mold body can be assembled and adjusted according to the length of the prefabricated parts to be processed, and can be used for processing of multiple sizes.

[0022] 2. By setting up positioning guide plates, restraint plates and multiple positioning steel strands, this invention can realize the overall assembly and one-time connection of multiple mold bodies, without the need for too many assembly parts, and the overall assembly and disassembly are more convenient.

[0023] 3. By setting multiple reinforcing mechanisms at the opening of the mold body, the present invention can prevent the opening from being stretched open after concrete pouring, and prevent the difference in size between the two ends and the middle. The setting of the reinforcing mechanisms can ensure the stability of the middle position. Attached Figure Description

[0041] A restraint plate 9 is set on one side of the end sealing plate 6. Multiple positioning steel strands 10 are fixedly connected to one side of the restraint plate 9. The positioning steel strands 10 pass through the steel strand through holes 11 and are in contact with the anchor clamp 17.

[0042] As one embodiment of the present invention, the reinforcing mechanism 3 includes multiple slide groove groups, and the slide groove groups are opened on the outer walls on both sides of the opening of the mold body 1. Each slide groove group includes two separate slide grooves 301. A card seat slider 302 and a rotating component slider 303 are slidably connected in the slide groove 301 respectively. A reinforcing rod 304 is rotatably connected to the rotating component slider 303. One end of the reinforcing rod 304 is fixedly connected to a card slot 305.

[0043] The slide groove 301 is equipped with a slide bar, and the card seat slider 302 and the rotating component slider 303 are slidably connected in the slide bar. The card seat slider 302 has a slot that matches the size of the carding component 305. One end of the reinforcing rod 304 is rotatably connected to the rotating component slider 303. When the reinforcing rod 304 rotates, it crosses the opening on the surface of the mold body 1. Then the carding component 305 and the card seat slider 302 are movably engaged to stabilize the distance at the opening.

[0044] In one embodiment of the present invention, a positioning rod 13 is fixedly connected to one side of the mold body 1 and the end sealing plate 4, and a corresponding positioning hole 12 is opened on the other side of the end sealing plate 6 and the mold body 1.

[0045] Among them, the positioning rods 13 are inserted into the positioning holes 12 respectively, and are matched with the size of the positioning holes 12, so that the connection between the mold body 1, the end sealing plate 4 and the end sealing plate 6 is more stable.

[0046] In one embodiment of the present invention, sealing protrusions are provided at both ends of the mold body 1, and the sealing protrusions are inserted into the end sealing grooves 7.

[0048] The mold body 1 has two ends inserted into the end sealing plate 4 and the end sealing plate 6, and the connection is sealed by the end sealing strip 8.

[0049] In one embodiment of the present invention, end blocking plate 18 is provided on both sides of end blocking plate 19, and steel bar through holes are respectively opened on end blocking plate 18 and end blocking plate 19.

[0050] Among them, end blocking plate 18 and end blocking plate 29 are respectively inserted into the blocking plate groove 20, and end blocking plate 18 and end blocking plate 29 on end sealing plate 26 are limited by binding plate 9, and the steel bars in the precast rib beam pass through the steel bar through hole.

[0051] In one embodiment of the present invention, one end of the lead screw 15 passes through the positioning guide plate 5 and is connected to the positioning guide plate 5 by a thread. The end of the lead screw 15 away from the pressure plate 16 is fixedly connected to a rocker handle 14. The pressure plate 16 is disposed on the surface of the end sealing plate 4.

[0052] Among them, the rocker arm 14 drives the lead screw 15 to rotate. When the lead screw 15 rotates, the support positioning guide plate 5 moves away from the end sealing plate 4, stretches the positioning steel strand 10, and fixes the entire assembled structure through the binding plate 9 and the positioning guide plate 5.

[0053] In one embodiment of the present invention, a plurality of anchor clamps 17 are movably disposed within the limiting clamping hole. The anchor clamps 17 are arranged in a ring array on the surface of the positioning steel strand 10.
