Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 5 The reusable formwork tool for concave concrete lines shown includes a formwork assembly 1 and a fixing assembly 2. The formwork assembly 1 includes a formwork material 12 and a formwork back rib 11 for reinforcing the formwork material 12. The fixing assembly 2 is used to detachably fix the formwork back rib 11 and the formwork material 12 to the precast component. The formwork material 12 is used to form a casting space 3 with the precast component. A forming groove 4 is provided on the formwork material 12 outside the casting space 3. With this utility model structure, the forming back rib is fixed to the forming mold material, and the forming back rib is fixed in conjunction with the precast component. The forming mold material and the precast component form a casting space. Since the forming mold material on the outside of the casting space is provided with a forming groove, after the casting space is completed, the casting structure and the precast component will form a concave line. On the other hand, since both the forming mold assembly and the fixing assembly are detachable, when it is necessary to remove the forming mold assembly, only the fixing assembly needs to be removed in sequence to remove the corresponding forming mold material and forming back rib. The forming mold assembly and the fixing assembly can also be disassembled and reused, realizing the turnover of formwork, with better construction quality, and greatly reducing labor and material removal costs. Preferably, the forming mold material 12 and the forming back rib 11 are made of aluminum material.

[0023] As a specific implementation and not a limitation, in order to better form the casting space 3, the molding material 12 includes an outer molding template assembly 121 and an inner molding template assembly 122. The fixing assembly 2 includes a plurality of tie rods 21, which penetrate the outer molding template assembly 121 and the inner molding template assembly 122, and fix the outer molding template assembly 121 and the inner molding template assembly 122 relative to each other to form the casting space 3. A cover panel 5 is included, connected to the molding back rib 11, and the cover panel 5 is used to form the casting space 3 with the inner molding template assembly 122. Since both the outer formwork assembly 121 and the inner formwork assembly 122 are fixed by means of through-hole tie rods 21, the fixing is achieved by tightening the nuts on the tie rods 21. This fixing method usually involves threading the tie rods 21 into a section of PC pipe. After the later casting and molding, the tie rods 21 can be disassembled simply by unscrewing the nuts and pulling them out of the PC pipe. This is very convenient. The connection of the formwork material 12 is relatively flat and has good sealing performance, resulting in good construction quality after casting.

[0024] Furthermore, in order to better realize the support and disassembly of the forming groove 4, the outer forming template assembly 121 includes a fixed template 1211, a first side wall template 1212, an outer wall template 1213, and an L-shaped template 1214. One end of the fixed template 1211 is provided with a first fixing part 12111 that is fixed to the precast component, and the other end is provided with a second fixing part 12112. One end of the first side wall template 1212 is provided with a third fixing part 12121 that is fixed to the second fixing part 12112, and the other end of the first side wall template is provided with a fourth fixing part 12122. The outer wall template 1213 is provided with a fifth fixing part 12131 that cooperates with and is fixed to the fourth fixing part 12122. One side of the outer wall template 1213 abuts against the L-shaped template 1214, and a gap is formed between the L-shaped template 1214 and the first side wall template 1212. The fixing component 2 includes a bolt assembly 22 and a plurality of pin assemblies 23. The bolt assembly 22 fixes the fixing template 1211 to the prefabricated component by passing through the first fixing part 12111. The pin assembly 23 passes through the second fixing part 12112 and the third fixing part 12121. Another pin assembly 23 passes through the fourth fixing part 12122 and the fifth fixing part 12131. The second fixing part 12112 and the third fixing part 12121 are inclined. The pin assembly 23 is a detachable fastener. The second fixing part 12112 and the third fixing part 12121 are both inclined, and the preferred inclination angle is 45°. The pin assembly 23 is fixed by passing through the second fixing part 12112 and the third fixing part 12121. When disassembling the mold, the mold back rib 11 is removed first. The inclination angle of 45° can easily remove the pin assembly 23. Then, the other pin assembly 23 is removed from the fourth fixing part 12122 and the fifth fixing part 12131, and the disassembly of the entire template can be completed. The operation is simple and convenient.

[0025] As a specific implementation and not a limitation, in order to better fix the precast component 1 to the building structure, the precast component includes a precast bay window, and the precast back rib 11 includes a first multi-corner back rib 111 and a straight back rib 114 away from the first multi-corner back rib 111. The first multi-corner back rib 111 and the straight back rib 114 are fixed by the tie rod 21. One end of the first multi-corner back rib 111 is fixed with a first corner back rib 112 by the tie rod 21. The tie rod 21 is fixed by sequentially penetrating the first corner back rib 112, the L-shaped template 1214, the prefabricated component and the first multiple corner back rib 111. The other end of the first corner back rib 112 is connected to the second multiple corner back rib 113. The corner of the first corner back rib 112 and the second multiple corner back rib 113 is fixed by the tie rod 21. The other tie rod 21 is fixed by penetrating the first corner back rib 112, the second multiple corner back rib 113 and the prefabricated component. All the formwork back ribs 11 are fixed with tie rods 21. The tie rods 21 can ensure the correct forming of the concrete structure, improve construction efficiency and reduce project cost. The tie rods are fixed by penetrating the formwork back ribs 11 and the precast bay window. The corners set by the first multi-corner back ribs 111, the first corner back ribs 112 and the second multi-corner back ribs 113 can fit with the structure of the precast bay window and are then fixed by the tie rods 21, which greatly improves the stability and strength of the formwork.

[0026] Furthermore, to secure the fixed template 1211 to the precast bay window and facilitate disassembly after fixing, the bolt assembly 22 includes an embedded sleeve 221 fixed to the precast bay window and a bolt 222 cooperating with the embedded sleeve 221. The embedded sleeve 221 and the bolt 222 cooperate to fix the fixed template 1211 to the precast bay window. A reserved gap will be formed between the fixed template 1211 and the precast bay window, with a width of 0-5mm. Leak-proof tape 223 is provided in the reserved gap. When it is necessary to disassemble the fixed template 1211, simply remove the bolt 222 from the embedded sleeve 221 to remove the fixed template 1211. A 5mm reserved gap will remain between the fixed template 1211 and the precast bay window. This reserved gap facilitates demolding, and the leak-proof tape 223 in the reserved gap prevents grout leakage.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
