Description

Technical Field

[0001] This utility model relates to the technical field of concrete pouring core mold fixing equipment, specifically to a concrete pouring core mold fixing device. Background Technology

[0002] ADS lightweight solid inner formwork is made of lightweight materials, significantly reducing its weight compared to traditional building materials. When used in structures such as large-span floor slabs and hollow core slabs, it effectively reduces the overall weight of the floor structure, decreasing the load on the substructure (such as beams, columns, and foundations), lowering the requirements for foundation bearing capacity, and thus saving on foundation materials and construction costs. However, during concrete pouring, the buoyancy generated by the liquid concrete is significant. When this buoyancy exceeds the weight of the inner formwork itself and the fixing force provided by existing measures, the inner formwork will float due to the imbalance of forces. Furthermore, when the concrete flows unevenly, it creates an uneven pressure distribution around the inner mold, causing the inner mold to shift due to lateral forces. Therefore, it is necessary to fix the inner mold. Patent No. CN202520459286.3 discloses a concrete pouring core mold fixing device, in which hooks are attached to the upper slab reinforcement of a large-span floor slab, and the bottom of the pressure plate abuts against the tops of two adjacent core molds. The entire fixing structure is securely tightened by a screw and an I-beam buckle. However, during the use of the concrete building core mold fixing device, the I-beam buckle and the screw are screwed together to provide tension to the hook. When rotating the I-beam buckle, the screw is prone to slippage or loosening due to the tightening force on the internal thread of the hook. To address this, we propose a concrete pouring core mold fixing device. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a concrete casting core mold fixing device.

[0004] The technical solution adopted by this utility model to solve its technical problem is a concrete casting core mold fixing device, including a hook body. The outer end surface of the hook body is provided with an insertion hole, and an insertion shaft for support is inserted into the inner side of the insertion hole. The inner circumferential surface of the insertion hole is provided with an F-shaped hanging groove for limiting the position, and there are two sets of F-shaped hanging grooves. The outer circumference of the insertion shaft is integrally constructed with a protrusion that engages with the F-shaped hanging groove, and there are multiple sets of protrusions. The end of the insertion shaft away from the insertion hole is integrally constructed with a screw body for limiting the position.

[0005] The lead screw body has an annular groove on the outer periphery of the insert shaft at one end, and a washer for auxiliary support is slidably installed on the outer periphery of the insert shaft. A spring for pushing the washer to move is assembled between the washer and the annular groove, and an I-beam fastener for fastening is screwed onto the outer periphery of the lead screw body.

[0006] By adopting the above technical solution, during the use of the concrete pouring core mold fixing equipment, the screw rod body is connected to the insertion hole on the hook body through the insertion shaft. At the same time, the multiple sets of protrusions on the outer periphery of the insertion shaft can fit and hook with the F-shaped hanging groove on the inner periphery of the insertion hole, which facilitates the improvement of the stability of the connection between the hook body and the screw rod body. In addition, the pouring core mold can be fixed by simply rotating the I-shaped fastener screwed on the outer periphery of the screw rod body, which is more convenient and stable to operate.

[0007] When the insert shaft and the hook body are inserted into each other, the spring in the annular groove on the outer periphery of the screw rod provides elastic thrust to the washer and facilitates the insertion shaft and the hook body to abut against each other when they are inserted into each other. When the protrusion on the outer periphery of the insert shaft and the F-shaped hanging groove are inserted into each other and then rotated and engaged with the hanging groove end on the F-shaped hanging groove, the reaction force of the spring on the washer can push the screw rod in the opposite direction, so that the screw rod can be stably engaged with the hook body through the protrusion on the outer periphery of the insert shaft. The subsequent screwing action of the screw rod and the I-beam fastener on the hook body can be more stable, which facilitates the fixation of the casting core mold.

[0008] Specifically, the lead screw has an arc-shaped groove on its outer periphery, and there are multiple sets of arc-shaped grooves.

[0009] By adopting the above technical solution, the multiple sets of arc-shaped grooves on the outer periphery of the lead screw can cooperate with the corresponding limit wrench, thereby assisting in rotating the I-beam fastener and making it easier to rotate the I-beam fastener.

[0010] Specifically, the end of the lead screw away from the insertion shaft is integrally constructed with a hexagon for rotation.

[0011] By adopting the above technical solution, the hexagonal body makes it easier to assemble and disassemble the lead screw, and it can also assist in rotating the I-beam fastener.

[0012] Specifically, a pad for limiting the position is inserted into the outer periphery of the hook body, and the surface of the pad has a concave hole that matches the bent part of the hook body, and there are multiple sets of concave holes.

[0013] By adopting the above technical solution, when the hook body is inserted into the upper slab reinforcement of the large span floor slab, it will abut against the pad plate on the outer side of the core mold. The bent part on the hook body can easily be inserted into the concave hole on the pad plate, which can further reduce the rotation of the hook body and distribute the pressure of the hook body on the upper slab reinforcement.

[0014] Specifically, the multiple sets of protrusions are evenly distributed on the outer periphery of the insert shaft.

[0015] By adopting the above technical solution, multiple sets of protrusions are evenly distributed on the outer periphery of the insert shaft and can correspond to the position of the F-shaped groove, so that the protrusions can stably fit and hook with the F-shaped groove, which facilitates the subsequent screw body and I-beam fastener to stably provide tension to the hook body and cooperate with each other, which facilitates the fixation of the casting core mold.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of the insertion hole, insertion shaft, F-type hanging groove, protrusion, screw rod body and I-beam fastener, allows the screw rod body to be inserted into the insertion hole on the hook body through the insertion shaft during the use of the concrete pouring core mold fixing equipment. At the same time, multiple sets of protrusions on the outer periphery of the insertion shaft can fit and hang with the F-type hanging groove on the inner periphery of the insertion hole, which facilitates the stability of the connection between the hook body and the screw rod body. In addition, the pouring core mold can be fixed by simply rotating the I-beam fastener screwed on the outer periphery of the screw rod body, and the operation is more convenient and stable.

[0018] 2. The technical solution of this application, through the design of annular groove, washer and spring, allows the spring in the annular groove on the outer periphery of the screw rod to provide elastic thrust to the washer when the insert shaft and the hook body are inserted. It also facilitates the engagement of the insert shaft and the hook body. When the protrusion on the outer periphery of the insert shaft engages with the F-shaped hanging groove and then rotates and engages with the hanging groove end on the F-shaped hanging groove, the reaction force of the spring on the washer can push the screw body in the opposite direction, so that the screw body can be stably engaged with the hook body through the protrusion on the outer periphery of the insert shaft. The subsequent screwing action of the screw body and the I-beam fastener on the hook body can be more stable, which facilitates the fixation of the casting core mold. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a concrete casting core mold fixing device, including a hook body 1, an insertion hole 2 is provided on the outer end surface of the hook body 1, and an insertion shaft 3 for support is inserted into the inner side of the insertion hole 2. An F-shaped hanging groove 4 for limiting is provided on the inner circumferential surface of the insertion hole 2, and there are two sets of F-shaped hanging grooves 4. The outer circumference of the insertion shaft 3 is integrally constructed with a protrusion 5 that engages with the F-shaped hanging groove 4, and there are multiple sets of protrusions 5. The end of the insertion shaft 3 away from the insertion hole 2 is integrally constructed with a screw body 6 for limiting. The end of the screw body 6 near the insertion shaft 3 is provided with an annular groove 7 located on the outer circumference of the insertion shaft 3, and a washer 8 for auxiliary support is slidably installed on the outer circumference of the insertion shaft 3. A spring 9 for pushing the displacement of the washer 8 is assembled between the washer 8 and the annular groove 7, and an I-beam fastener 10 for fastening is screwed on the outer circumference of the screw body 6.

[0026] When using the concrete pouring core mold fixing equipment, the screw rod 6 is inserted into the insertion hole 2 on the hook body 1 through the insertion shaft 3. At the same time, the multiple sets of protrusions 5 on the outer periphery of the insertion shaft 3 can fit and hook into the F-shaped hanging groove 4 on the inner periphery of the insertion hole 2, which can improve the stability of the connection between the hook body 1 and the screw rod 6. At the same time, the pouring core mold can be fixed by simply rotating the I-shaped fastener 10 screwed on the outer periphery of the screw rod 6, which is more convenient and stable to operate.

[0027] When the insert shaft 3 and the hook body 1 are inserted into each other, the spring 9 in the outer circumferential groove 7 of the screw body 6 can provide elastic thrust to the washer 8, and facilitate the insertion shaft 3 and the hook body 1 to abut against each other when they are inserted into each other. When the protrusion 5 on the outer circumference of the insert shaft 3 and the F-type hanging groove 4 are inserted into each other and then rotated and engaged with the hanging groove end on the F-type hanging groove 4, the reaction force of the spring 9 on the washer 8 can push the screw body 6 in the opposite direction, so that the screw body 6 can be stably engaged with the hook body 1 through the protrusion 5 on the outer circumference of the insert shaft 3. Subsequently, the screw body 6 and the I-beam fastener 10 are screwed together and the pulling force on the hook body 1 can be more stable, which facilitates the fixing of the casting core mold.

[0028] like Figure 1 As shown, the outer periphery of the lead screw body 6 is provided with an arc-shaped groove 11, and there are multiple sets of arc-shaped grooves 11.

[0029] When in use, the multiple sets of arc grooves 11 on the outer periphery of the lead screw body 6 can cooperate with the corresponding limit wrench to assist in rotating the I-beam fastener 10, making it easier to rotate the I-beam fastener 10.

[0030] like Figure 1As shown, the end of the lead screw body 6 away from the insertion shaft 3 is integrally constructed with a hexagonal body 12 for rotation.

[0031] When in use, the hexagon 12 makes it easier to assemble and disassemble the lead screw 6, and also assists in rotating the I-beam fastener 10.

[0032] like Figure 1 and Figure 2 As shown, a pad 13 for limiting is inserted into the outer periphery of the hook body 1, and the surface of the pad 13 is provided with a concave hole 14 that matches the bent part of the hook body 1, and there are multiple sets of concave holes 14.

[0033] When in use, the hook body 1 is inserted into the upper slab reinforcement of the large span floor slab and abuts against the pad 13 on the outer side of the core mold. The bent part on the hook body 1 can easily be inserted into the recessed hole 14 on the pad 13, which can further reduce the rotation of the hook body 1 and distribute the pressure of the hook body 1 on the upper slab reinforcement.

[0034] like Figure 2 As shown, multiple sets of protrusions 5 are evenly distributed on the outer periphery of the insert shaft 3.

[0035] In use, multiple sets of protrusions 5 are evenly distributed on the outer periphery of the insert shaft 3 and correspond to the position of the F-shaped groove, so that the protrusions 5 can stably fit and hook with the F-shaped groove, which makes it convenient for the subsequent screw body 6 and the I-shaped fastener 10 to stably provide tension to the hook body 1 and cooperate with each other, which facilitates the fixing of the casting core mold.

[0036] The working principle and usage process of this utility model are as follows: In use, first, install the corresponding structural components in suitable positions. During the use of the concrete pouring core mold fixing device, the lead screw 6 is inserted into the insertion hole 2 on the hook body 1 via the insertion shaft 3. Simultaneously, multiple sets of protrusions 5 on the outer periphery of the insertion shaft 3 can engage with and hang on the F-shaped hanging groove 4 on the inner periphery of the insertion hole 2, improving the stability of the connection between the hook body 1 and the lead screw 6. Furthermore, simply rotating the I-beam fastener 10 screwed onto the outer periphery of the lead screw 6 is sufficient to fix the pouring core mold, making operation more convenient and stable. Also, when the insertion shaft 3 and the hook body 1 are inserted into each other... When connected, the spring 9 in the outer circumferential groove 7 of the lead screw body 6 can provide elastic thrust to the washer 8, and facilitate the mutual abutment of the insert shaft 3 and the hook body 1 when they are inserted together. When the protrusion 5 on the outer circumference of the insert shaft 3 and the F-type hanging groove 4 are inserted together and then rotated and engaged with the hanging groove end on the F-type hanging groove 4, the reaction force of the spring 9 on the washer 8 can push the lead screw body 6 in the opposite direction, so that the lead screw body 6 can be stably engaged with the hook body 1 through the protrusion 5 on the outer circumference of the insert shaft 3. Subsequently, the tension of the lead screw body 6 and the I-beam fastener 10 on the hook body 1 can be more stable, which facilitates the fixing of the casting core mold.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
