[0002] In the field of prefabricated buildings and cast-in-place concrete engineering, steel formwork frames serve as an important temporary support system for construction. Their connection reliability, assembly and disassembly efficiency, and reusability directly affect the project quality and construction costs. Therefore, connectors are generally required between adjacent prefabricated steel formwork frames to ensure the strength of the connection.

Therefore, it is necessary to improve the steel formwork frame structure to solve the above problems. Utility Model Content

[0033] Example 1:

[0034] Please see Figure 1-5 This utility model provides a technical solution: a steel formwork frame structure, including a steel formwork 1 and a steel structure side plate 4. A bottom insert rod 5 and a top insert rod 6 are inserted at the contact position between the steel formwork 1 and the steel structure side plate 4. A positioning insert rod 7 is fixedly installed at the bottom of the top insert rod 6. A positioning mechanism 2 is provided at the top of the bottom insert rod 5. A fixing mechanism 3 is provided on the outside of the bottom insert rod 5.

[0035] Furthermore, the positioning mechanism 2 includes a fixing frame 21, which is fixedly installed on the top of the bottom insert rod 5. A trapezoidal insert block 1 22 is fixedly installed on the left side of the fixing frame 21, the bottom insert rod 5, and the top insert rod 6. A trapezoidal insert block 23 is fixedly installed on the back of the fixing frame 21, the bottom insert rod 5, and the top insert rod 6. A fixing plate 24 is inserted into the left side of the fixing frame 21, and a fixing side plate 25 is inserted into the back of the fixing frame 21. Through the insertion and cooperation of the trapezoidal insert blocks 22 / 23 with the dovetail groove, and in conjunction with the cross-penetration of the fixing rods 32 / 35, the precise positioning of the steel template 1, the side plate 4, and the fixing frame 21 is achieved.

[0036] Furthermore, the fixing frame 21 has slots at the corresponding positions of the positioning rod 7, and the positioning rod 7 is inserted into the slots. The height of the fixing frame 21 is higher than the height of the steel template 1 and the steel structure side plate 4, which facilitates the positioning operation of the multi-layer steel template 1 and the steel structure side plate 4 and saves alignment time.

[0037] Furthermore, dovetail grooves are provided at the corresponding positions of the steel formwork 1 and the steel structure side plate 4 and the trapezoidal insert 1 22 and the trapezoidal insert 23, and the trapezoidal insert 1 22 and the trapezoidal insert 23 are located inside the dovetail grooves.

[0038] Furthermore, trapezoidal blocks are fixedly installed on the outer sides of the fixing plate 24 and the fixing side plate 25, and dovetail grooves are opened at the corresponding positions of the fixing frame 21 and the trapezoidal blocks. The trapezoidal blocks are set inside the dovetail grooves. The dovetail groove design ensures the pre-fixing strength and facilitates the pre-fixing operation of the steel template 1, the steel structure side plate 4, the fixing plate 24 and the fixing side plate 25.

[0039] Example 2:

[0040] Please see Figure 5-6 Furthermore, in conjunction with Embodiment 1, the fixing mechanism 3 includes a mounting plate 31, which is disposed on the front of the fixing frame 21. A fixing rod 32 is fixedly installed on the back of the mounting plate 31. A high-strength bolt 33 is threaded inside the fixing frame 21. A mounting side plate 34 is disposed on the right side of the fixing frame 21. A fixing rod 35 is fixedly installed on the left side of the mounting side plate 34. A high-strength bolt 36 is threaded inside the fixing frame 21. The fixing rods 32 / 35 are inserted into the steel structure side plate 4, the positioning rod 7, and the fixing plates 24 / 25 to form a three-dimensional mesh fixing structure, thereby increasing the compressive strength of the device.

[0041] Furthermore, four sets of fixing rods 35 are provided, and slots are opened at the corresponding positions of the steel template 1, fixing frame 21, fixing plate 24, positioning rod 7 and trapezoidal block 22 and fixing rods 35. Fixing rods 35 are inserted into the slots, and the two fixing rods 35 on the back are respectively inserted into the corresponding slots of the upper and lower steel templates 1. By using the cross-penetration method of fixing rods 32 / 35, the reinforcement operation on the upper and lower sides is realized, and the fixing effect is increased.

[0042] Furthermore, four sets of fixing rods 32 are provided, and slots are opened at the corresponding positions of the steel structure side plate 4, fixing frame 21, fixing side plate 25, positioning plug 7 and trapezoidal plug 23 and fixing rods 32, and fixing rods 32 are inserted into the slots. The two fixing rods 32 on the left are respectively inserted into the slots corresponding to the upper and lower steel structure side plates 4.

[0043] Furthermore, when the first fixing rod 32 is inside the fixing frame 21, it is positioned inside the second fixing rod 35, so that the first fixing rod 32 and the second fixing rod 35 form a spatially intersecting layout, so that the first fixing rod 32 and the second fixing rod 35 do not interfere with each other during insertion, thereby increasing the fixing effect.

[0044] Furthermore, high-strength bolt 33 passes through the mounting plate 31 and is threaded inside the fixing frame 21, and high-strength bolt 36 passes through the mounting side plate 34 and is threaded inside the fixing frame 21. The mechanical fit between the high-strength bolt 33 and the trapezoidal insert increases the compressive strength of the device.

[0045] In actual operation, when this device is used, the steel template 1 and the steel structure side plate 4 form a frame. The trapezoidal insert 1 22 and trapezoidal insert 23 on the outside of the four sets of fixing frames 21 are inserted into the outside of the steel template 1 and the steel structure side plate 4 respectively. After the top insert rod 6 is inserted into the inside of the fixing frame 21 through the positioning insert rod 7, the dovetail grooves of the top steel template 1 and the steel structure side plate 4 are inserted into the outside of the corresponding trapezoidal insert 1 22 and trapezoidal insert 23. The fixing plate 24 and the fixing side plate 25 are inserted into the corresponding dovetail grooves of the fixing frame 21 to perform the pre-fixing operation of the steel module frame.

[0046] After removing the mounting plate 31, pass the fixing rod 32 through the fixing frame 21, the positioning rod 7, and the trapezoidal block 23 in sequence, and finally insert it into the steel structure side plate 4 and the fixed side plate 25. Insert the two sets of fixing rods 32 on the left into the upper and lower steel structure side plates 4. Thread the high-strength bolts 33 into the fixing frame 21 to complete the fixing and limiting operation of the upper and lower steel structure side plates 4 and the fixed side plate 25. Pass the fixing rod 32 through the fixing frame 21, the positioning rod 7, and the trapezoidal block 22 in sequence, and finally insert it into the steel template 1 and the fixed plate 24. Insert the two sets of fixing rods 35 on the back into the upper and lower steel templates 1 respectively to complete the fixing operation of the upper and lower steel templates 1 and the fixed plate 24. Then, stabilize the remaining corners in sequence.

[0047] Furthermore, the present invention has been described in detail above with reference to the accompanying drawings and embodiments. Those skilled in the art can make various modifications to the present invention based on the above description. Therefore, certain details in the embodiments should not be construed as limiting the present invention, and the scope of protection of the present invention shall be defined by the appended claims.
