Description

Technical Field

[0001] This utility model relates to the field of steel truss technology, specifically to a prefabricated detachable steel truss floor deck formwork splicing structure. Background Technology

[0002] With the rapid development of the construction industry, the requirements for construction efficiency, quality, and safety are constantly increasing. While traditional cast-in-place concrete slab construction methods are widely used, they suffer from problems such as long construction cycles, large amounts of on-site wet work, high resource consumption, and environmental pollution. To address these issues, prefabricated building technology has gradually gained attention and is being widely applied.

[0003] However, existing devices have the following problems when in use: First, traditional template splicing mostly requires manual precise measurement and marking to ensure the alignment accuracy between each template. However, this method is easily affected by human factors, resulting in large splicing errors, which in turn affect the quality of the entire building structure. Second, in order to ensure the firmness of the connection during the template splicing process, a large number of bolts, nails or other fasteners are usually required. The installation process of these fasteners is cumbersome and time-consuming, which not only increases the labor intensity of workers, but may also lead to instability of the spliced ​​parts due to the loosening or failure of the fasteners, posing a safety hazard. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a prefabricated and detachable steel truss floor slab formwork splicing structure, which allows for quick and stable splicing of adjacent bottom formwork and is easy to use.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A prefabricated detachable steel truss floor deck formwork splicing structure includes a bottom formwork. Connecting components are provided on both the left and right sides of the bottom of the bottom formwork. The connecting components include connecting half-rings, which are fixedly installed on the bottom formwork. A rotating semi-circular plate is rotatably installed on the connecting half-ring. A sliding groove is provided on the connecting half-ring for the rotating semi-circular plate to slide. A locking component is provided on the connecting half-ring. A positioning component is provided on the bottom formwork.

[0007] Preferably, the two connecting half-rings on the left and right sides of the bottom of the bottom template can be spliced ​​together to form a complete circle. At this time, the sliding grooves on the two connecting half-rings are connected.

[0008] Preferably, a connecting plate is fixedly installed on the rotating semicircular plate, and a movable groove is provided on the connecting semicircular plate for the connecting plate to slide, and the movable groove is connected to the sliding groove.

[0009] Preferably, the locking assembly includes a limiting plate and a mounting block. The limiting plate is fixedly mounted on the connecting half ring, and the mounting block is fixedly mounted and connected to the connecting plate. The mounting block has a mounting cavity, and a pinch block is slidably mounted inside the mounting block. A spring is fixedly mounted inside the mounting block, and the other end of the spring is fixedly mounted on the pinch block. The limiting plate has a limiting groove on the side facing the pinch block that can accommodate the pinch block.

[0010] Preferably, there are two limit plates on the same connecting half ring, with the two limit plates located at the beginning and end of the moving groove, respectively.

[0011] Preferably, the positioning component includes positioning blocks, which are equidistantly disposed on the side of the bottom template, and the bottom template has positioning holes at corresponding positions to accommodate the positioning blocks.

[0012] Preferably, a sealing gasket is inlaid on the surface of the bottom template where the positioning hole is opened.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1 to 7 A prefabricated detachable steel truss floor slab formwork splicing structure includes a bottom formwork 1. Connecting components are provided on both the left and right sides of the bottom of the bottom formwork 1. The connecting components are used to realize the rapid connection and stable splicing between different bottom formworks 1.

[0025] The connecting assembly includes a connecting half-ring 3, which is fixedly installed on the bottom template 1. A rotating semi-circular plate 6 is rotatably installed on the connecting half-ring 3, and a groove 11 is provided on the connecting half-ring 3 for the rotating semi-circular plate 6 to slide.

[0026] A locking component is provided on the connecting semi-ring 3. The locking component is used to ensure that the rotating semi-circular plate 6 can be safely locked after being adjusted to the correct position, preventing accidental loosening or displacement.

[0027] The bottom template 1 is equipped with a positioning component, which facilitates quick and accurate docking between templates.

[0028] The two connecting half-rings 3 on the left and right sides of the bottom of the bottom template 1 can be spliced ​​together to form a complete circle. At this time, the sliding grooves 11 on the two connecting half-rings 3 are connected.

[0029] When the two connecting semi-rings 3 are spliced ​​into a complete circle, the rotating semi-circular plate 6 on the left can rotate in the groove 11 on the right connecting semi-ring 3, and the rotating semi-circular plate 6 on the right can rotate in the groove 11 on the left connecting semi-ring 3. By allowing the rotating semi-circular plate 6 to enter the groove 11 in the other connecting semi-ring 3, the splicing activity of the adjacent bottom template 1 can be completed.

[0030] A connecting plate 12 is fixedly installed on the rotating semicircular plate 6. A sliding groove 10 is provided on the connecting semiring 3 for the connecting plate 12 to slide. The sliding groove 10 is connected to the sliding groove 11. The presence of the sliding groove 10 allows the rotating semicircular plate 6 to be smoothly adjusted in position during splicing.

[0031] The locking assembly includes a limiting plate 7 and a mounting block 8. The limiting plate 7 is fixedly mounted on the connecting half ring 3. The mounting block 8 is fixedly connected to the connecting plate 12. The mounting block 8 has a mounting cavity 13. A pinch block 9 is slidably mounted inside the mounting block 8. A spring 14 is fixedly mounted inside the mounting block 8. The other end of the spring 14 is fixedly mounted on the pinch block 9. The limiting plate 7 has a limiting groove 15 on the side facing the pinch block 9 to accommodate the pinch block 9.

[0032] The locking mechanism can be controlled by manually operating the pinch block 9. When force is applied to the pinch block 9, under the action of the spring 14, the pinch block 9 returns to the mounting cavity 13 inside the mounting block 8. At this time, the pinch block 9 retracts from the limiting groove 15, and the rotating semicircular plate 6 can rotate smoothly. After the rotating semicircular plate 6 moves to the corresponding position, the force applied to the pinch block 9 is released, and the elastic force of the spring 14 causes the pinch block 9 to automatically spring into the limiting groove 15 of the limiting plate 7, ensuring the stability of the rotating semicircular plate 6 in the locked state.

[0033] There are two upper limit plates 7 on the same connecting half ring 3. The two limit plates 7 are located at the beginning and end of the moving groove 10, respectively, ensuring that the rotating semicircular plate 6 has two stable fixed states, one unused state and one used state.

[0034] The positioning component includes positioning blocks 2, which are equidistantly located on the side of the bottom template 1. The bottom template 1 has positioning holes 4 at corresponding positions to accommodate the positioning blocks 2, which are used to precisely align adjacent bottom templates 1, ensuring the positioning of the entire splicing structure and facilitating quick and accurate docking between templates. When inserted into the corresponding center, the two connecting half-rings 3 on the left and right sides of the bottom of the bottom template 1 are spliced ​​together to form a complete circle, facilitating the smooth progress of subsequent splicing activities.

[0035] A sealing gasket 5 is inlaid on the surface of the bottom template 1 with positioning holes 4. After the bottom template 1 is assembled, the sealing gasket 5 can fill the tiny gaps between the bottom templates 1 to prevent grout leakage during concrete pouring.

[0036] The working process of this utility model is as follows: the positioning block 2 is inserted into the corresponding positioning hole 4, so that the adjacent bottom template 1 is tightly connected, and the sealing gasket 5 fills the tiny gaps to prevent grout leakage during concrete pouring.

[0037] At this time, the connecting half-rings 3 on the left and right sides of the adjacent bottom template 1 will be joined together to form a complete circle. At this time, the sliding grooves 11 on the two connecting half-rings 3 are connected, allowing the rotating semi-circular plate 6 to move in the sliding groove 11 of the other connecting half-ring 3.

[0038] When force is applied, the pinch block 9 retracts into the mounting cavity 13 and releases the lock; this causes the left rotating semicircular plate 6 to rotate in the groove 11 on the right connecting semiring 3, and the right rotating semicircular plate 6 to rotate in the groove 11 on the left connecting semiring 3. By causing the rotating semicircular plate 6 to enter the groove 11 in the other connecting semiring 3, the splicing activity of the adjacent bottom template 1 can be completed. When the rotating semicircular plate 6 reaches the designated position, the pinch block 9 is released. Under the action of the spring 14, the pinch block 9 automatically springs into the limiting groove 15 to ensure the stability of the rotating semicircular plate 6.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
