Description

Technical Field

[0001] The present invention relates to the field of ribbed membrane shells, and particularly to a ribbed membrane shell structure that is convenient for disassembly and assembly. Background Art

[0002] The membrane shell is a formwork used for teaching ribbed floor slabs. Usually, a full paving formwork is arranged below the membrane shell, and the full paving formwork is supported by a steel pipe scaffold. During the construction process, the steel pipe scaffold is first erected, then the full paving formwork is set, and finally the membrane shell is fixed on the full paving formwork. When disassembling, the steel pipe scaffold is first removed from below, then the full paving formwork is removed, and finally the membrane shell is removed. Therefore, from the perspective of workers, when installing, the workers are constructing from above, and when disassembling, the workers are constructing from below. However, since the workers are constructing from above during the installation in the early stage, many connecting parts such as bolts are more convenient to operate from above. When disassembling, it is actually not convenient to operate from below. Therefore, how to enable smooth construction whether the workers are above or below is the technical problem to be solved by this solution. Summary of the Invention

[0003] To solve the above technical problems, the present invention provides a ribbed membrane shell structure that is convenient for disassembly and assembly. Workers can carry out smooth construction whether they are above or below. The structure of the worm and worm gear can achieve a one-way locking effect. The driving force can only be transmitted from the driving rod to the transition rod and cannot be transmitted reversely to the driving rod, making the fixation of the membrane shell more stable.

[0004] The technical solution adopted by the present invention to solve its technical problems is: a ribbed membrane shell structure that is convenient for disassembly and assembly, characterized in that it includes a membrane shell and a connection component;

[0005] The port of the membrane shell extends outwards with an end edge;

[0006] The connection component includes a full paving formwork, a positioning seat, and a clamping block;

[0007] The positioning seats are distributed between adjacent membrane shells. The positioning seats are fixed to the full paving formwork, and clamping blocks are respectively arranged on both sides of the positioning seats;

[0008] A driving rod is vertically arranged in the positioning seat. Both ends of the driving rod extend to the upper side and the lower side of the positioning seat respectively. Screwing heads are respectively arranged at both ends of the driving rod. A worm segment is arranged inside the positioning seat corresponding to the driving rod. A transition rod is rotatably arranged in the positioning seat corresponding to the driving rod. A worm wheel meshing with the worm segment is arranged on the transition rod. The outer end of the transition rod extends to the outside of the positioning seat and is provided with a screw segment. The screw segment is in threaded cooperation with the clamping block, and the clamping block is connected to the end edge of the membrane shell;

[0009] The full paving formwork is provided with a screwing window corresponding to the screwing head.

[0010] The rotation of the driving rod in this solution is fitted to the positioning seat, and a screwing head extends vertically. Therefore, the driving rod can be rotated from above or from below. When the driving rod rotates, it drives the worm gear of the transition rod through the worm section, causing the transition rod to rotate. When the transition rod rotates, it drives the clamping block to approach or move away from the positioning seat, so as to adjust the distance between the membrane shell and the positioning seat. Among them, the full paving formwork serves as the support structure below the positioning seat, and the full paving formwork, like the conventional one, is supported by brackets such as steel pipe scaffolds.

[0011] In this solution, since the two ends of the driving rod that controls the transition rod extend vertically, on the one hand, the distance between the membrane shells can be adjusted by rotating the driving rod above during the erection process. On the other hand, during formwork removal, the screwing head below can be rotated through the screwing window under the full paving formwork to rotate the transition rod and adjust the distance between the clamping plate and the formwork, making formwork removal more convenient. And this solution adopts the structure of worm and worm gear, which can achieve the effect of one-way locking. The driving force can only be transmitted from the driving rod to the transition rod and cannot be transmitted reversely to the driving rod, making the fixation of the membrane shell more stable.

[0012] Preferably, the worm gear is located in the middle of the transition rod, the two ends of the transition rod extend to the outside of the positioning seat, and the screw sections are located at the two ends of the transition rod. The thread directions of the screw sections at the two ends of the same transition rod are opposite. That is, one driving rod can control two clamping blocks at the same time, causing the clamping blocks on both sides to approach or move away.

[0013] Preferably, a soft sleeve is provided on the screwing head at the upper end of the driving rod. To prevent the driving rod from sticking to the concrete, the soft sleeve can be used to contact the concrete, and during later disassembly, the soft material can also be removed more easily.

[0014] Preferably, the soft sleeve is made of foam material. It can provide a certain support strength while having a lower hardness.

[0015] Preferably, a soft material is filled between the clamping block and the positioning seat. During disassembly, the soft material is easier to remove.

[0016] Preferably, the soft material is made of foam material. It can provide a certain support strength while having a lower hardness.

[0017] Preferably, the clamping block is a U-shaped part, a stop block and a pull rod. The stop block is arranged opposite to the port of the U-shaped part. The U-shaped part clamps the outer edge of the end side. The stop block abuts against the inner wall of the membrane shell. One end of the pull rod is connected to the stop block, and the other end of the pull rod passes through the U-shaped part and is fixed by a nut.

[0018] The membrane shell and the clamping plate can be well fixed by the U-shaped part, the stop block and the pull rod, and the fixation is more firm. It is very convenient to move inward and outward, and with the cooperation of nuts, it is more convenient to disassemble and assemble.

[0019] Preferably, a bottom plate in contact with the full-laying module is arranged below the matching part to provide support for the U-shaped part.

[0020] Advantages of the present invention:

[0021] With this solution, it is very convenient to disassemble and assemble the membrane shell. During installation, the membrane shell can be fixed from above, and during disassembly, the membrane shell can be removed from below, which is more in line with the construction rules. Whether from above or below, the connection between the fixed seat and the membrane shell can be controlled by rotating the screwing head.

[0027] To deepen the understanding of the present invention, the following will further describe the present invention in detail with reference to the drawings and embodiments. This embodiment is only used to explain the present invention and does not limit the protection scope of the present invention.

[0028] Embodiment

[0029] As Figure 1 shown, a ribbed membrane shell structure convenient for disassembly and assembly, characterized in that it includes a membrane shell 1 and a connection assembly;

[0030] The port of the membrane shell 1 extends outward with an end edge 2;

[0031] The connection assembly includes a full-laying template 13, a positioning seat 7 and a clamping block;

[0032] The positioning seats 7 are distributed between adjacent membrane shells 1. The positioning seats 7 are fixed to the full paving formwork 13. Clamping blocks are respectively arranged on both sides of the positioning seats 7;

[0033] A driving rod is vertically arranged in the positioning seat 7. Both ends of the driving rod extend to the upper side and the lower side of the positioning seat 7 respectively. Wringing heads 8 are respectively arranged at both ends of the driving rod. A worm segment 9 is arranged inside the positioning seat 7 corresponding to the driving rod. A transition rod is rotatably arranged in the positioning seat 7 corresponding to the driving rod. A worm gear 11 meshing with the worm segment 9 is arranged on the transition rod. The outer end of the transition rod extends to the outside of the positioning seat 7 and is provided with a screw segment 10. The screw segment 10 is in threaded cooperation with the clamping block. The clamping block is connected to the end edge 2 of the membrane shell 1;

[0034] The full paving formwork 13 is provided with a wringing window 12 corresponding to the wringing head 8.

[0035] In this solution, the rotation of the driving rod is matched with the positioning seat 7, and the wringing heads 8 extend upward and downward. Therefore, the driving rod can be rotated from above or from below. When the driving rod rotates, the worm gear 11 of the transition rod is driven by the worm segment 9, so that the transition rod rotates. When the transition rod rotates, it drives the clamping block to approach or move away from the positioning seat 7, so as to adjust the distance between the membrane shell 1 and the positioning seat 7. Among them, the full paving formwork 13 serves as a support structure below the positioning seat 7. The full paving formwork 13 provides support through brackets such as steel pipe scaffolds as usual.

[0036] In this solution, since the driving rod controlling the transition rod extends upward and downward at both ends, on the one hand, the distance between the membrane shells 1 can be adjusted by rotating the driving rod above during the erection process. On the other hand, when demolishing the formwork, the lower wringing head 8 can be rotated through the wringing window 12 below the full paving formwork 13 to rotate the transition rod and adjust the distance between the clamping plate and the formwork, which is more convenient for formwork demolition. And this solution adopts the structure of the worm gear 11 and the worm 9, which can achieve the effect of one-way locking. The driving force can only be transmitted from the driving rod to the transition rod and cannot be transmitted reversely to the driving rod, so that the membrane shell 1 is fixed more stably.

[0037] Preferably, the worm gear 11 is located in the middle of the transition rod. Both ends of the transition rod extend to the outside of the positioning seat 7. The screw segments 10 are located at both ends of the transition rod. The thread directions of the screw segments 10 at both ends of the same transition rod are opposite. That is, one driving rod can control two clamping blocks at the same time, so that the clamping blocks on both sides approach or move away. The wringing head 8 at the upper end of the driving rod is provided with a soft sleeve. To prevent the driving rod from sticking to the concrete, the soft sleeve can be used to contact the concrete, and the soft material can be removed more easily during later disassembly.

[0038] The soft sleeve is made of foam material. While providing a certain support strength, it has a lower hardness. A soft material is filled between the clamping block and the positioning seat 7. During disassembly, the soft material is easier to remove. The soft material is made of foam material. While providing a certain support strength, it has a lower hardness. The clamping block includes a U-shaped member 5, a stopper 3 and a pull rod 4. The stopper 3 is disposed opposite to the port of the U-shaped member 5. The U-shaped member 5 is clamped on the outer edge of the end edge 2. The stopper 3 abuts against the inner wall of the membrane shell 1. One end of the pull rod 4 is connected to the stopper 3. The other end of the pull rod 4 passes through the U-shaped member 5 and is fixed by a nut 6. Through the U-shaped member 5, the stopper 3 and the pull rod 4, the membrane shell 1 and the clamping plate can be well fixed, the fixing is more firm, the inner and outer movement is very convenient, and with the cooperation of the nut 6, the disassembly and assembly can be more convenient.

[0039] A bottom plate in contact with the full-laying module is provided below the mating portion. So as to provide support for the U-shaped member 5.

[0040] Through this solution, the disassembly and assembly of the membrane shell 1 can be realized very conveniently. During installation, the membrane shell 1 can be fixed from above. During disassembly, the membrane shell 1 can be disassembled from below, which is more in line with the construction rules. Whether from above or below, the connection between the fixed seat and the membrane shell 1 can be controlled by rotating the screwing head 8.

[0041] During actual installation, a single membrane shell requires multiple connection components to provide sufficient support.

[0042] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0043] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
