Description

Technical Field

[0001] This utility model relates to the field of precast floor slab construction applications, and in particular to a novel precast floor slab post-pouring strip hoisting formwork device. Background Technology

[0002] Because prefabricated buildings are inherently green and environmentally friendly, a certain proportion of prefabricated components are used in construction projects. Among these, precast floor slabs are the most widely used. The pouring of the post-cast strip between precast floor slabs is crucial during installation, as it directly affects the overall construction quality. Currently, the formwork erection at the post-cast strip of precast floor slabs still uses traditional methods: first, scaffolding is erected, and then wooden formwork is placed on top of it. This traditional method not only affects the on-site construction space but also involves a cumbersome process, poor stability, poor sealing, and significant material waste. Furthermore, it is prone to grout leakage and other problems.

[0003] Therefore, in order to address these shortcomings, there is an urgent need for a new type of precast floor slab post-pouring strip hoisting device to solve the above problems, so as to comprehensively improve functionality, stability and convenience. Summary of the Invention

[0004] The purpose of this utility model is to overcome the aforementioned problems in the existing technology and provide a novel precast slab post-pouring strip formwork hoisting device. To achieve the above technical objective and effect, this utility model is implemented through the following technical solution:

[0005] A novel precast floor slab post-cast strip hoisting device comprises a precast floor slab, a hoisting template, a pad, positioning tenons, positioning grooves, fastening connecting rods, fastening nuts, reserved reinforcing bars, reserved bolt holes, a reinforcing plate, rubber washers, and a handle. Reserved reinforcing bars are provided at the ends of the precast floor slab, with the reserved reinforcing bars of adjacent precast floor slabs staggered. Reserved bolt holes are provided on the precast floor slab, and the hoisting template has reserved bolt holes corresponding to those on the precast floor slab. A pad is placed on top of the precast floor slab, with reserved bolt holes corresponding to those on the pad. Four fastening connecting rods are evenly spaced on the reinforcing plate and welded to the reinforcing plate. The top of the fastening connecting rods is threaded. The hoisting template is fixedly connected to the precast floor slab via the fastening connecting rods and fastening nuts.

[0006] Preferably, the front end of the hanging mold template is provided with a positioning tenon, and the rear end of the hanging mold template is provided with a positioning groove.

[0007] Preferably, the depth of the positioning tenon should not be less than 50mm, and the groove depth of the positioning groove should not be less than 50mm.

[0008] Preferably, a handle is provided on the bottom surface of the hanging formwork template.

[0009] Preferably, the lifting mold template, the positioning tenon, and the positioning groove are an integral structure, and the lifting mold template and the handle are an integral structure.

[0010] Preferably, rubber gaskets are provided on both sides of the long side of the top surface of the hanging mold template.

[0011] The beneficial effects of this utility model are as follows: To improve the formwork efficiency of post-cast strips in precast floor slabs and simplify the construction process, and to solve problems such as poor stability and tightness of formwork support, serious material waste, and easy grout leakage, this new type of precast floor slab post-cast strip formwork hanging device can effectively solve the above-mentioned problems. This new type of precast floor slab post-cast strip formwork hanging device has a positioning tenon at the front end of the hanging formwork with a depth of not less than 50mm, and a positioning groove at the rear end with a groove depth of not less than 50mm. This not only greatly improves the formwork installation efficiency but also enhances the firmness and tightness of the formwork splicing. To facilitate the installation and disassembly of the formwork, a handle is provided on the bottom surface of the hanging formwork. To improve the integrity and stability of the formwork, the hanging formwork, positioning tenon, positioning groove, and handle are integrated into a single structure. To protect the precast floor slab and prevent grout leakage during concrete pouring, rubber gaskets are provided on both sides of the long side of the top surface of the hanging formwork.

[0012] The method of using this utility model is as follows: First, place the first hanging formwork template at the post-pouring strip position of the two precast floor slabs, aligning the hanging formwork template with the reserved bolt holes of the precast floor slabs. Then, insert the fastening connecting rod into the reserved bolt holes, and place the pad through the fastening connecting rod on the top surface of the precast floor slab. Tighten each fastening connecting rod with the fastening nut. When installing the second hanging formwork template, first insert the positioning protrusion at the front end of the second hanging formwork template into the positioning groove at the rear end of the first hanging formwork template to complete the splicing of the two hanging formwork templates. Then, repeat the above steps to fix the second hanging formwork template. Repeat the above steps until the formwork of the post-pouring strip of the precast floor slab is completed. Finally, pour the concrete. After the concrete reaches the required strength, loosen the fastening nut and remove the pad, fastening connecting rod and hanging formwork template in sequence to complete the pouring of the post-pouring strip of the precast floor slab.
