Description

Technical Field

[0001] This invention relates to a template locking device structure and operation method, belonging to the field of building equipment technology. Background Technology

[0002] In recent years, with the rapid development of urban construction, the quality requirements for building civil engineering and municipal infrastructure projects have become increasingly stringent. Besides high standards and requirements for the structural safety and stability of various types of concealed works, the acceptance of surface concrete is also becoming increasingly rigorous. In traditional concrete formwork erection projects, formwork locking is achieved using tie rods in conjunction with other components (butterfly buckles, double steel pipes, etc.).

[0003] Chinese patent CN205348783U discloses a tie bolt structure for formwork support reinforcement, including a fiberglass reinforced bolt passing through the shear wall and the formwork on both sides of the shear wall. The fiberglass reinforced bolt has butterfly buckles at both ends, clamping rings that abut against the outside of the butterfly buckles to clamp the bolt, and nuts that are threaded to the outside of the clamping rings to lock them in place. However, during concrete pouring, various factors can cause the bolts to loosen or even fall off due to vibration, resulting in poor concrete forming quality. Forming problems generally include misalignment and bulging. In large-volume concrete pouring (enclosed spaces, such as fire pools) where manpower is difficult to reach, this can even lead to formwork bursting. Therefore, designing a structurally stable formwork locking device that can prevent the device from falling off and causing poor concrete forming quality is of great significance. Summary of the Invention

[0004] In order to solve the above-mentioned problems in the prior art, the present invention provides a template locking device structure and operation method, which can prevent the screws on both sides of the template from falling off, thereby preventing problems such as poor concrete molding quality.

[0005] The technical solution of the present invention is as follows:

[0006] A template locking device includes a staggered screw rod passing through templates on both sides of a wall. Streamlined butterfly buckles are respectively installed on the staggered screw rod on both sides of the wall, with the butterfly buckles tightly abutting against the templates on both sides. Screw sleeves inserted into the staggered screw rod are abutted against the outer sides of the butterfly buckles on both sides. Nuts are rotatably installed on the outside of the screw sleeves to ensure a tight threaded connection between the screw sleeves and the staggered screw rod. Each turn of the external thread of the staggered screw rod is staggered, and after the screw sleeves and the staggered screw rod are tightly threadedly connected by the nuts, the screws can only advance forward.

[0007] The external thread on the outer wall of the misaligned screw has the same helix direction as the internal thread on the inner wall of the sleeve. The external thread on the outer wall of the misaligned screw produces an axially misaligned fault every 1 / 3 turn, and the projection of the external thread on the vertical plane along the axial direction of each turn of the misaligned screw forms a complete circle. The internal thread on the inner wall of the sleeve produces an axially misaligned fault every 1 / 3 turn, and forms a notch along the helical direction. The projection of the internal thread on the vertical plane along the axial direction of each turn of the sleeve forms a circle with three annularly distributed openings.

[0008] The threaded sleeve has three equally spaced partitions on its outer side away from the top of the streamlined butterfly buckle, dividing it into three bolt pieces. The internal threads of the threaded sleeve are respectively provided on the three bolt pieces, and each of the three bolt pieces has an inwardly recessed cutting edge on its outer wall. The inner wall of the nut has a protrusion that fits the cutting edge. When the protrusion is misaligned with the cutting edge, the bolt piece clamps the misaligned screw through the nut protrusion. When the protrusion fits the cutting edge, a gap remains between the bolt piece and the misaligned screw.

[0009] The streamlined butterfly buckle includes two buckle feet for fitting the template, and the buckle feet are provided with serrated patterns; the inner side of the two buckle feet is provided with an inner groove for locking the steel pipe.

[0010] The streamlined butterfly buckle has a locking block on its outer side, and the end of the threaded sleeve that abuts against the outer side of the streamlined butterfly buckle has a fastening block that engages with the locking block; the locking block and the fastening block cooperate to restrict the threaded sleeve from shifting up and down due to vibration of the misaligned screw.

[0011] The threaded portion of the misaligned screw is staggered with each turn, with a spacing of 1mm between each turn. After the screw sleeve and the misaligned screw are tightly connected by a nut, they can only be screwed forward 1mm at a time.

[0012] This includes the following steps:

[0013] S1. After passing through the concrete formwork on both sides with staggered screws, streamlined butterfly buckles are screwed into both sides to make it press against the formwork on both sides and clamp it.

[0014] S2. Insert two threaded sleeves into both sides of the misaligned screw respectively;

[0015] S3. Tighten the screw sleeve by fitting a nut onto the outer wall of the screw sleeve, so that the screw sleeve is firmly engaged with the misaligned screw rod;

[0016] S4. Screw the sleeve inward until it is tightly pressed against and fixed to the back of the streamlined butterfly buckle, and clamp the templates on both sides.

[0017] The threaded sleeve and the streamlined butterfly buckle are fixed together by a fastening block and a locking block.

[0018] The present invention has the following beneficial effects:

[0019] This device involves fitting a threaded sleeve onto a misaligned screw rod and then using the compression of a nut to ensure a tight fit between the sleeve and the rod. The misaligned structure of the screw rod ensures that the sleeve can only be screwed in, not out, thus guaranteeing the stability of the overall structure and preventing the device from easily falling off due to external factors.

[0020] This device secures the threaded sleeve and the streamlined butterfly buckle together using fastening blocks and locking blocks, making the connection between the threaded sleeve and the misaligned screw tighter and preventing them from coming loose. Attached Figure Description

[0027] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] Please see Figure 1 , Figure 2 The invention provides a technical solution:

[0029] A template locking device includes a staggered screw 1 passing through templates on both sides of a wall. Streamlined butterfly buckles 2 are respectively provided on the staggered screw 1 on both sides of the wall, and the streamlined butterfly buckles 2 are tightly attached to the templates on both sides. Threaded sleeves 3 inserted into the staggered screw 1 are abutted against the outer sides of the streamlined butterfly buckles 2. Nuts 4 are rotatably installed on the outside of the threaded sleeves 3 to make the threaded sleeves 3 tightly threadedly connected to the staggered screw 1. Each turn of the external thread of the staggered screw 1 is staggered and spaced apart. After the threaded sleeves 3 and the staggered screw 1 are tightly threadedly connected by the nuts 4, they can only be screwed forward.

[0030] Furthermore, the outer section of the threaded sleeve 3, away from the top and adjacent to the streamlined butterfly buckle 2, is provided with three equally spaced partition openings 32. The three partition openings 32 divide the threaded sleeve 3 into three bolt pieces 31. The internal threads of the inner wall of the threaded sleeve 3 are respectively provided on the three bolt pieces 31. Each of the three bolt pieces 31 has an inwardly recessed cutting edge 33 on its outer wall. The inner wall of the nut 4 has a protrusion that fits the cutting edge 33. When the protrusion is misaligned with the cutting edge 33, the bolt piece 31 is used to clamp the misaligned screw rod 1 through the protrusion of the nut 4. When the protrusion aligns with the cut edge 33, a gap remains between the bolt piece 31 and the misaligned screw 1. Specifically, when the nut 4 is not installed on the bolt piece 31 and the threaded sleeve 3 rests against the outside of the streamlined butterfly buckle 2, a gap remains between the threaded sleeve 3 and the misaligned screw 1 passing through it, allowing for free insertion and removal. When the protrusion of the nut 4 aligns with the cut edge 33, the nut 4 is just aligned with the bolt piece 31. When the nut 4 is rotated, the protrusion on the inner wall of the nut 4 will rotate and thus misalign with the cut edge 33 until it presses against the bolt piece. When the bolt piece 31 protrudes from the cutting edge 33, the nut 4 and the bolt piece 31 are not in a perfectly matched state. Therefore, the bolt piece 31 is subjected to an inward force from the nut 4, which causes the bolt piece 31 to be squeezed inward and tightly engaged with the misaligned screw 1. The external thread direction of the outer wall of the misaligned screw 1 is consistent with the internal thread direction of the inner wall of the screw sleeve 3. Every 1 / 3 turn of the external thread on the outer wall of the misaligned screw 1 produces an axial misalignment fault. Every turn of the external thread of the misaligned screw 1 is projected along the vertical plane of the axial direction. The shadow forms a complete circle; the internal thread of the inner wall of the threaded sleeve 3 produces an axially misaligned fault every 1 / 3 turn, and forms a notch along the helical direction. The projection of the internal thread of the threaded sleeve 3 in the vertical plane along the axial direction forms a circle with three annularly distributed openings; when the bolt piece 31 is pressed inward and tightly engaged with the misaligned screw 1, the fault generated by the external thread of the misaligned screw 1 and the fault generated by the internal thread of the inner wall of the threaded sleeve 3 cooperate with each other, and the bolt piece 31 can only be screwed forward. Specifically, as shown in... Figure 3 As shown, there is a gap between the external threads on the outer wall of each two adjacent turns of the misaligned screw 1 to match the internal threads on the inner wall of the sleeve 3. When the internal threads on the inner wall of the sleeve 3 are screwed inward every 1 / 3 turns, the sleeve 3 and the misaligned screw 1 can be tightly connected by the nut 4 and screwed forward. However, when the internal threads on the inner wall of the sleeve 3 are screwed outward every 1 / 3 turns, the internal threads on the inner wall of the sleeve 3 will abut against the external threads on the outer wall of the misaligned screw 1 at the point of axial misalignment, and thus cannot be retracted.

[0031] Furthermore, the streamlined butterfly buckle 2 includes two buckle feet 21 for fitting the template, and the buckle feet 21 are provided with serrated patterns; the inner side of the two buckle feet 21 is provided with an inner groove 22 for locking the steel pipe.

[0032] A further streamlined butterfly buckle 2 has a locking block 23 on its outer side, and a fastening block 34 that engages with the locking block 23 is provided at the end of the threaded sleeve 3 that abuts against the outer side of the streamlined butterfly buckle 2. The locking block 23 and the fastening block 34 cooperate to limit the up-and-down displacement of the threaded sleeve 3 due to vibration of the misaligned screw 1. Specifically, the locking block 23 includes three locking teeth with gaps between them, and the gaps and locking teeth are the same size. The locking teeth include protrusions and concave blocks. The structure of the fastening block 34 is the same as that of the locking block 23. After the locking teeth on the fastening block 34 pass through the gaps of the locking block 23, they can be rotated to make the locking teeth on the fastening block 34 and the locking teeth on the locking block 23 be in the same position. In this state, the protrusions on the locking teeth on the locking block 23 are embedded in the concave blocks on the locking teeth on the fastening block 34, and the protrusions on the locking teeth on the locking block 23 hook onto the protrusions of the locking teeth on the locking block 23, thereby limiting the up-and-down displacement.

[0033] Furthermore, the threaded portion of the misaligned screw 1 is staggered with each turn, and the spacing between each turn is 1mm. After the screw sleeve 3 and the misaligned screw 1 are tightly connected by the nut 4, they can only be screwed forward 1mm each time.

[0034] The operating method applicable to this template locking device includes the following steps:

[0035] S1. After passing through the concrete formwork on both sides by the staggered screw rod 1, the streamlined butterfly buckle 2 is screwed into the formwork on both sides to make it press against the formwork on both sides and clamp it.

[0036] S2. Insert two threaded sleeves 3 into both sides of the misaligned screw 1 respectively; specifically, insert the threaded sleeves 3 into the outside of the misaligned screw 1 and push them against the outside of the streamlined butterfly buckle 2 to ensure the clamping force into the template on both sides.

[0037] S3. By fitting a nut 4 onto the outer wall of the threaded sleeve 3 to lock the threaded sleeve 3, the threaded sleeve 3 is tightly engaged with the misaligned screw 1. Specifically, after the threaded sleeve 3 is inserted into the misaligned screw 1, there is a gap between the two, allowing for free insertion and removal. When the protrusion of the nut 4 engages with the cutting edge 33, the nut 4 is just in contact with the bolt piece 31. Therefore, when the protrusion on the inner wall of the nut 4, misaligned with the cutting edge 33, abuts against the bolt piece 31, the bolt piece 31 can be squeezed inward under force and tightly engaged with the misaligned screw 1 due to the partition opening 32 provided at intervals in all three bolt pieces 31. In addition, the threaded part of the misaligned screw 1 is misaligned and disconnected, so the bolt piece 31 can only be screwed forward, and the thread engagement only advances and does not retreat.

[0038] S4. Screw the threaded sleeve 3 inward until it is tightly pressed against and fixed to the back of the streamlined butterfly buckle 2, and clamp the templates on both sides; so that the fastening block 34 on the threaded sleeve 3 and the locking block 23 on the back of the streamlined butterfly buckle 2 engage with each other to complete the fixation.

Any equivalent structural or procedural transformations made based on the content of the present invention's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
