In this embodiment, a floor reserved hole hanging die device is disclosed, the device supports the system firmly, can firmly fix the template body at the bottom of the floor reserved hole, has effectively improved the efficiency of construction. Fig. 1 shows the structure of the floor slab preformed hole hanging die device, and fig. 2 shows the cross-sectional structure of the lifting assembly.

Referring to fig. 1 and 2, the floor slab preformed hole hanging die device comprises: the template comprises a template body, a plurality of diagonal braces 3, a lifting assembly, an adjusting rod 5 and a base plate 6. Wherein, the cross section of template body is "T" shape, including the first plate body 21 of level setting and the second plate body 22 of vertical setting, each bracing 3 slope sets up on the template body, and its one end fixed connection is at the outer end of first plate body 21, and the other end fixed connection is at the middle part of second plate body 22. As shown in fig. 1, the diagonal brace 3 is connected with the first plate body 21 and the second plate body 22 to form a stable triangle structure, so that the diagonal brace can well fix and support the template body in the construction process. A lifting assembly is fixedly connected to the lower end of the second plate 22, and includes an inner upright 41, an outer upright 42 and a cross bar 43. Specifically, the upper end of the inner upright 41 is fixedly connected to the lower end of the second plate 22, the upper end of the outer upright 42 is sleeved on the inner upright 41, and a plurality of clamping grooves 44 are uniformly formed in the inner upright 41 and the outer upright 42, and when in use, the cross rod 43 is inserted into the clamping grooves 44 to fix the inner upright 41 and the outer upright 42 together. In addition, a straight rack 411 extending outwards towards the lower end is fixedly arranged in the inner upright 41, a gear 421 capable of being meshed with the straight rack 411 is arranged in the outer upright 42, an adjusting rod 5 is rotatably connected to one side of the outer upright 42, the inner end of the adjusting rod 5 is inserted into the gear 421 and can drive the gear 421 to synchronously rotate, and a base plate 6 is further arranged at the lower end of the outer upright 42.

In this example, rotating the adjusting lever 5 clockwise brings the gear 421 to rotate together in the clockwise direction, and then drives the inner pole 41 to rise through the transmission between the gear 421 and the straight rack 411, thereby raising the device as a whole. Conversely, the inner uprights 41 are lowered, so that the device as a whole is lowered. In actual use, the floor reserved hole die lifting device is moved to the ground of the floor 1 below the reserved hole, the adjusting rod 5 is rotated clockwise, the gear 421 rotates along with the adjusting rod 5 in the clockwise direction, and the inner upright 41 is driven to rise through the transmission between the gear 421 and the straight rack 411. After the device is raised to the proper position and the formwork body is secured to the bottom of the preformed hole of the floor 1, the rail 43 is inserted into the slot 44 to secure the device. The template body transmits the load to the lifting assembly through the diagonal braces 3, and the load is uniformly transmitted to the floor slab 1 through the backing plate 6, so that a stable supporting system can be formed by connecting and supporting the structures with each other, and the template body is firmly fixed at the bottom of the reserved hole. In addition, after the construction is accomplished, the form removal is also more nimble, can also guarantee the roughness and the precision on concrete surface after the form removal, and the device simple structure simultaneously, convenient operation can effectively improve the efficiency of construction, reduces construction cost.

In other embodiments, the lifting direction of the inner pole 41 may be reversed when the adjusting lever 5 is turned. For example, when the adjusting lever 5 is rotated clockwise, the gear 421 is also rotated clockwise, and the straight rack 411 engaged with the gear 421 is moved downward by the driving of the gear 421, so that the inner pole 41 is driven to be lowered, thereby lowering the entire device. Conversely, the inner uprights 41 are raised, so that the device as a whole is raised. In practical use, the above-mentioned effects can be achieved no matter what transmission mode is.

In the embodiment, the template body is made of aluminum alloy, and the aluminum template is light in weight, high in strength, good in stability, flexible in demolding and reusable. After the construction is completed and the form is removed, the flatness and the precision of the concrete surface can be ensured, and the construction site environment can be protected. In addition, the aluminum template is a common material in building construction, has a simple structure, is convenient to manufacture, can obviously improve the construction efficiency, and reduces the construction cost.

In this embodiment, four diagonal braces 3 are uniformly distributed on the template body, and a stable supporting system can be formed between each diagonal brace 3 and the template body, so that the load borne by the template body can be uniformly transferred to other components, and the overall stability of the device is ensured, so that the template body is firmly fixed at the bottom of the reserved hole.

In this embodiment, the diagonal braces 3, the inner uprights 41 and the outer uprights 42 are square tubes, have high strength, can bear large loads, and uniformly transfer the loads to the ground of the floor slab 1 through the backing plate 6, so as to ensure that the device can provide a relatively stable supporting force for the formwork body in use.

It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
