Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a connecting and locking device for building formwork. Background Art

[0002] Building formwork is a temporary support structure, which is made according to the design requirements to make the concrete structure and components take shape at the specified positions and geometric dimensions, keep their correct positions, and bear the self-weight of the building formwork and the external loads acting on it. When pouring the columns of a building, multiple arc-shaped building formworks are used to be spliced into a cylindrical shape, so as to shape the poured concrete. At present, when splicing multiple arc-shaped building formworks into a cylindrical shape, nails are used to fix adjacent building formworks together. In order to reinforce multiple arc-shaped building formworks, sometimes a fixing rod or a fixing plate is also used for assistance, and the fixing rod or the fixing plate is also fixed on the building formwork by nails. After the pouring is completed and the building formwork is disassembled, due to the nails being driven in, the building formwork will be damaged, which will directly affect the service life of the building formwork. Therefore, a connecting and locking device for building formwork is needed to meet the requirements. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0020] Embodiment 1: Refer to Figures 1-4, a building formwork connection and locking device, including a plurality of arc-shaped clamping plates 1 and four insertion plates 5. The plurality of clamping plates 1 are symmetrically arranged in pairs and at equal intervals. The circle formed by splicing every two symmetric clamping plates 1 and the cylinder formed by splicing a plurality of arc-shaped building formworks are coaxially arranged, and both of the two symmetric clamping plates 1 are in contact with the surfaces of the plurality of building formworks;

[0021] Fixed plates 2 are fixed at both ends of each clamping plate 1. Grooves 3 are provided on each fixed plate 2. Fixed columns 4 are fixed on the fixed plates 2 in each groove 3. Each insertion plate 5 is sleeved through a plurality of fixed columns 4 and inserted into a plurality of grooves 3. The grooves 3 on the fixed plates 2 limit the position of the insertion plates 5 so that the insertion plates 5 will not slide on the fixed plates 2. Bolt assemblies 6 are provided at both ends of every two insertion plates 5. With the assistance of the bolt assemblies 6, the insertion plates 5 are pressed tightly in the plurality of grooves 3 on the plurality of fixed plates 2, so that the distance between the two symmetrically arranged insertion plates 5 is fixed, and thus the plurality of arc-shaped clamping plates 1 are limited on the plurality of building formworks spliced into a cylinder.

[0022] During use, the plurality of arc-shaped clamping plates 1 clamp the plurality of building formworks spliced into a cylinder. With the assistance of the plurality of bolt assemblies 6, the plurality of arc-shaped clamping plates 1 are clamped and fixed on the plurality of building formworks spliced into a cylinder by using the plurality of insertion plates 5, so that the plurality of building formworks are spliced into a cylinder without damage. After disassembly at the end of use, there will be no damage due to installation and disassembly, which can extend the service life of the building formworks and enable the building formworks to be reused.

[0023] Embodiment 2: In Embodiment 1, since each insertion plate 5 has to be sleeved on a plurality of fixed columns 4, and there is no measuring mechanism between the upper and lower adjacent clamping plates 1, it is necessary for the staff to adjust the position of one of the clamping plates 1 multiple times so that each insertion plate 5 can be sleeved on a plurality of fixed columns 4, which is time-consuming and laborious. Referring to Figure 1 、 3 、4 and 5, as another preferred embodiment of the present invention, different from Embodiment 1, an isolation mechanism is commonly fixed between the upper and lower adjacent clamping plates 1. The distance between the upper and lower adjacent clamping plates 1 is limited by the isolation mechanism, so that each insertion plate 5 can be accurately and quickly sleeved on a plurality of fixed columns 4, saving time and effort;

[0024] The isolation mechanism includes two fixed blocks 7, both of the two fixed blocks 7 are fixed on two adjacent upper and lower clamping plates 1. Each fixed block 7 is provided with a threaded hole 8 penetrating through it. A support rod 9 is arranged between the two fixed blocks 7. Threaded rods 14 are fixed on both ends of the support rod 9. The two threaded rods 14 are respectively screwed into the two threaded holes 8 in the two fixed blocks 7. The diameter of the threaded rod 14 is smaller than the diameter of the support rod 9. By turning the support rod 9, the threaded rods 14 at both ends of the support rod 9 can be respectively screwed into the two threaded holes 8 in the two fixed blocks 7 until both ends of the support rod 9 are in contact with the two fixed blocks 7 respectively. While the support rod 9 supports the two adjacent upper and lower clamping plates 1, the distance between the two adjacent upper and lower clamping plates 1 is also limited.

[0025] A knocking mechanism is arranged on each support rod 9. The knocking mechanism includes a cylinder 10, the cylinder 10 is rotatably sleeved on the support rod 9. Two connecting rods 11 are symmetrically fixed on the cylinder 10. Knocking balls 12 are respectively fixed on the two connecting rods 11. The cylinder 10 can rotate on the support rod 9. Therefore, when turning the support rod 9 to adjust the insertion lengths of the two threaded rods 14 in the two threaded holes 8 respectively, the two connecting rods 11 will not affect the rotation of the support rod 9. A fixed rod 13 is fixed on the cylinder 10 between the two connecting rods 11. The fixed rod 13 is used to facilitate the left - right rotation of the cylinder 10, so that the two knocking balls 12 alternately knock on the building formwork to assist the rapid demoulding of the building formwork.

[0026] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
