[0003] There is a kind of plastic template on the market. The entire template is made of plastic injection molding. A quick-release hole groove is molded on the back of the template. A pin is passed through the two quick-release hole grooves on the two templates and then rotated 90 degrees. A card block perpendicular to it is molded at the bottom of the pin. The pin is rotated so that the card block and the quick-release hole groove are misaligned, thereby completing the connection and fixation of the two templates. Its operation is simple and efficient.

[0004] However, when the plastic formwork is in use, its pins are kept fixed by the friction between the pins, blocks and the formwork. During long-term use and disassembly, the pins, blocks and the contact parts of the formwork with the pins and blocks will wear out, which will reduce the friction between the pins, blocks and the formwork. The vibration of the equipment during the casting construction process will cause the pins to deflect, which will in turn affect the assembly stability of the formwork. Based on this, a casting formwork for construction is provided. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] See also Figures 1 to 5In an embodiment of the present invention, a construction casting template includes a template assembly 1 consisting of a template body 101, a rectangular reinforcement frame 102, a corner connector 103, and a quick-install hole groove 104, and a clamping assembly 2. The rectangular reinforcement frame 102 is fixed to the back of the template body 101. The quick-install hole grooves 104 are respectively opened on the two corner sides of the corner connector 103, the upper and lower ends and both sides of the rectangular reinforcement frame 102. The clamping assembly 2 penetrates the two rectangular reinforcement frames 102 or the two quick-install hole grooves 104 on the rectangular reinforcement frame 102 and the corner connector 103 to realize the assembly and fixation of the template body 101. The clamping assembly 2 includes a clamping unit and a limiting unit.

[0031] The snap-fit ​​unit is used to realize the assembly and fixation of two template bodies 101 or the template body 101 and the corner connector 103;

[0032] The limiting unit is used to limit the rotation of the clamping unit;

[0033] The clamping unit includes a top block 201, a pin 202, and a straight clamping block 203;

[0034] The quick-install hole slot 104 is composed of a circular hole slot and two linear slots symmetrically distributed on both sides of the circular hole slot;

[0035] The top block 201, the pin 202, and the straight block 203 are fixed in sequence. The outer diameter of the pin 202 matches the inner diameter of the circular hole. The outer diameter of the top block 201 is larger than the inner diameter of the circular hole. The outer wall shape of the straight block 203 matches the inner wall shape of the linear slot.

[0036] The pin 202 is inserted into the two circular slots and the straight block 203 is completely passed through the two circular slots and deflected 90 degrees to achieve the assembly and fixation of the two template bodies 101 or the template body 101 and the corner connector 103;

[0037] The limiting unit includes a rotation slot 204, an L-shaped slot 205, a handle portion 206, an L-shaped block 207, and an L-shaped spring piece 208;

[0038] The rotation groove 204 is formed on the top of the top block 201, and the L-shaped groove 205 is formed inside the pin 202. The vertical groove of the L-shaped groove 205 extends through the inside of the top block 201 and communicates with the rotation groove 204. The horizontal groove of the L-shaped groove 205 extends to the outside of the pin 202.

[0039] The handle portion 206 is rotatably connected to the inner side of the rotation slot 204 , and the L-shaped block 207 is distributed inside the L-shaped slot 205 . The top of the L-shaped block 207 is fixed to the bottom end of the handle portion 206 , and the lateral portion of the L-shaped block 207 protrudes to the outside of the pin 202 ;

[0040] The horizontal portion of the L-shaped clamping block 207 is perpendicular to the straight clamping block 203, and the horizontal portion of the L-shaped clamping block 207 is clamped to the inner side of the straight slot to achieve the rotation limit of the pin 202;

[0041] The L-shaped spring piece 208 is distributed on the inner side of the L-shaped groove 205 and the horizontal part of the L-shaped spring piece 208 protrudes to the outside of the pin 202 and is fixedly connected to the horizontal part of the L-shaped block 207. The top of the vertical part of the L-shaped spring piece 208 is tightly fitted to the inner wall side of the L-shaped groove 205.

[0042] In this embodiment, the steps for assembling the template assembly 1 are as follows:

[0043] When assembling two upper and lower template bodies or two horizontal template bodies 101, they are directly aligned one by one through the quick-installation slots 104 on the rectangular reinforcement frame 102. When splicing two vertically distributed template bodies 101, it is necessary to place the corner connector 103 between the two vertically distributed template bodies 101 so that the quick-installation slots 104 on the corner connector 103 are aligned one by one with the quick-installation slots 104 on the rectangular reinforcement frame 102.

[0044] Afterwards, the clamping assembly 2 is taken out, and the straight card strip 203 is aligned with the quick-release slot 104 and inserted (it should be noted that the straight card strip 203 is aligned with the straight notch on the quick-release slot 104). During this process, the staff will hold the handle portion 206 and apply a pushing force toward the straight card strip 203. The handle portion 206 will deflect, and the handle portion 206 will drive the L-shaped card block 207 to retract into the L-shaped slot 205. The L-shaped spring piece 208 is further deformed under the force. At this time, the L-shaped card block 207 is completely retracted into the L-shaped slot 205, and will not affect the insertion operation of the straight card strip 203.

[0045] When the straight clip 203 completely passes through the two quick-install slots 104 and the pin 202 completely fills the circular slots of the two quick-install slots 104, a rotational thrust is applied to the entire clamping assembly 2, causing the entire clamping assembly 2 to deflect ninety degrees. At this time, the straight clip 203 and the straight slots on the quick-install slots 104 are vertically offset, thereby achieving the connection and fixation between the two rectangular reinforcement frames 102 or the rectangular reinforcement frame 102 and the corner connector 103 (it should be noted that the height of the pin 202 is the same as the splicing thickness of the two rectangular reinforcement frames 102 or the splicing thickness of the rectangular reinforcement frame 102 and the corner connector 103);

[0046] At the same time, the lateral part of the L-shaped block 207 is aligned with the straight slot of the quick-release hole slot 104, and the pressure on the handle part 206 is released. The L-shaped block 207 and the handle part 206 will automatically reset under the reset elastic force of the L-shaped spring piece 208. The lateral part of the L-shaped block 207 protrudes to the outside of the pin 202 and is clamped to the inside of the straight slot of the quick-release hole slot 104. At this time, the pin 202 cannot rotate. Compared with the traditional pin structure that relies on friction to remain stationary, it can effectively avoid the situation where stability is reduced due to wear, and further improve the assembly stability of the template component 1.

[0047] Please refer to Figures 3-5 The lower surface of the transverse portion of the L-shaped spring piece 208 is an arc-shaped structure, and there is a gap between the lower surface of the transverse portion of the L-shaped spring piece 208 and the bottom of the L-shaped groove 205.

[0048] In this embodiment, due to the arc structure of the horizontal portion of the L-shaped spring piece 208, when the straight bar block 203 is inserted into the quick-install slot 104, the arc surface of the L-shaped spring piece 208 is squeezed, which can cause the L-shaped block 207 to retract into the L-shaped slot 205.

[0049] There is a gap between the lower surface of the horizontal portion of the L-shaped spring piece 208 and the bottom of the L-shaped groove 205 to provide space for the L-shaped block 207 and the L-shaped spring piece 208 to be stored and turned over.

[0050] Please refer to Figures 1 to 5 The top block 201, the pin 202, the straight block 203, the rotating groove 204, and the L-shaped groove 205 are integrally formed by an injection molding process, and the handle 206, the L-shaped block 207, and the L-shaped spring 208 are integrally formed by an injection molding process.

[0051] In this embodiment, the clamping assembly 2 is divided into two parts as a whole, and its structure is simple, which is convenient for production and assembly, and further convenient for promotion and use.

[0052] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
