[0002] Construction engineering refers to the engineering entity formed by the construction of various building houses and their affiliated facilities and the installation activities of the pipelines and equipment supporting them. Among them, "building houses" refers to those with roofs, beams, columns, walls, foundations and capable of forming internal spaces. When processing concrete precast parts, a PC wallboard mold is required.

[0003] The PC wallboard molds of concrete precast components under the existing technology can basically meet people's usage requirements. However, before pouring the wallboard, a steel bar mesh layer needs to be woven inside the mold cavity. The ends of the steel bars usually need to be placed in the positioning grooves on the side walls of the mold. To prevent the concrete from leaking along the positioning grooves, sealing blocks are required to seal the positioning grooves. However, during the demolding process, the sealing blocks will stick to the side walls of the wallboard, making it difficult to demold. Summary of the Invention

[0018] Furthermore, the auxiliary module part includes:

[0019] The rotating member is installed on the side wall of the positioning member. The rotating member is used to drive the bottom of the cover plate to be fixed on the side wall of the fixed angle block;

[0020] The auxiliary fastening member is installed at the bottom of the cover plate. The auxiliary fastening member cooperates with the rotating member, so that the auxiliary fastening member drives the cover plate to be closely attached to the side wall of the fixed angle block;

[0021] The demolding part is installed inside the side guard plate. The rotating part drives the demolding part to slide inside the side guard plate. The demolding part is used for demolding the side guard plate, and the side guard plate drives a number of first sealing blocks and second sealing blocks to be demolded.

[0025] The usage method of the PC wallboard mold for precast concrete components includes the following steps:

[0026] Step 1: Assemble the mold. First, assemble the device. At this time, the sliding card slots at both ends of a number of side guard plates are stuck on the connecting convex blocks between the two fixed angle blocks. Push the side guard plates inward along the connecting convex blocks. At this time, insert the fastening bolts into the first fixed sliding groove and tighten them with the side wall of the fixed angle block. At this time, increase the contact area between the fastening bolts and the side guard plates through the pressing pieces on the fastening bolts, so as to make the fixing effect between the side guard plates and the fixed angle blocks better;

[0027] Step 2: Positioning and assembly. The construction workers put the ends of the steel bars laid in the mold cavity into the steel bar positioning grooves. At this time, put the first sealing blocks into the side guard plates along the sealing sliding grooves, and use the first sealing blocks to further fix the ends of the steel bars. At this time, multiple steel bar meshes can be placed in the steel bar positioning grooves to improve the practicability of the device; when the steel bar meshes are laid, cover the cover plate directly above the side guard plates. At this time, a number of second sealing blocks at the bottom of the cover plate move along the sealing sliding grooves towards the ends of the steel bars;

[0028] Step 3: Rotate and fix. When the cover plate is installed, the connecting plate at the bottom of the cover plate drives the sliding sleeve to be sleeved on the rotating rod. At this time, the initial state of the moving block is located at one end of the threaded groove close to the limiting block. Use a pneumatic wrench to rotate the interface bolt, and the interface bolt drives the rotating rod to rotate. At this time, the moving block drives the pressing disc at one end of the sliding sleeve to squeeze against the side wall of the side guard plate. This setting is beneficial to assist the fastener to fix the cover plate on the side wall of the side guard plate and strengthen the stability of the device structure;

[0029] Step 4: Demold the wall panel. When it is necessary to demold the concrete after it has solidified, first loosen the fastening bolt. At this time, use a pneumatic wrench to drive the rotating rod to rotate in the reverse direction, and the moving block moves towards the end close to the limiting block. At this time, the linkage rod drives the top die plate at one end of the ejector post to squeeze against the side wall of the wall panel, and the reaction force of the wall panel on the top die plate drives the entire sliding card slots at both ends of the side guard plate to slide outwards along the connecting convex blocks on the fixed angle block. At this time, the inner wall of the side guard plate and the side wall of the wall panel are demolded under the reaction force of the wall panel on the top die plate.

[0030] The present invention has the following beneficial effects:

[0031] (1). In the present invention, by setting a demolding member, when pouring concrete, the rotating rod drives the moving block to move, and the moving block drives the ejector post at one end of the linkage rod to slide outwards along the side guard plate towards the inner cavity of the mold, providing a complete pouring space for the mold. When it is necessary to demold the solidified concrete, the moving block moves towards the end close to the limiting block. At this time, the linkage rod drives the top die plate at one end of the ejector post to squeeze against the side wall of the wall panel, and the reaction force of the wall panel on the top die plate drives the entire sliding card slots at both ends of the side guard plate to slide outwards along the connecting convex blocks on the fixed angle block. At this time, the inner wall of the side guard plate and the side wall of the wall panel are demolded under the reaction force of the wall panel on the top die plate. This setting improves the demolding efficiency of the wall panel.

[0032] (2). In the present invention, when the side guard plate is separated from the side wall of the wall panel, remove the cover plate. At this time, the side guard plate drives a number of sealing blocks one and two inside the side guard plate to separate from the inner wall of the wall panel. This setting avoids the adhesion of the sealing blocks one and two to the side wall of the wall panel. At this time, by removing the cover plate, the cover plate brings out a number of sealing blocks two inside the side guard plate. When the wall panel is taken out, the ends of the steel bars bring out a number of sealing blocks one inside the sealing chute, thus facilitating the recycling of the sealing parts.

[0033] (3). In the present invention, when using the PC wall panel mold of the concrete precast member, first assemble the device. At this time, the sliding card slots at both ends of several side guard plates are stuck on the connecting protrusions between two fixed corner blocks, and push the side guard plates inward along the connecting protrusions. Then insert the fastening bolts into the first fixed sliding groove and tighten them with the side walls of the fixed corner blocks. At this time, the pressing pieces on the fastening bolts increase the contact area between the fastening bolts and the side guard plates, so that the fixing effect between the side guard plates and the fixed corner blocks is better. In addition, the cross-section of the side guard plate is in the shape of a Chinese character 'Ri', which is beneficial to replacing the reinforcing ribs in the prior art and making the structure of the side guard plate stable.

[0034] (4). In the present invention, by setting a seal, the construction worker puts the end of the steel bar laid in the inner cavity of the mold into the steel bar positioning groove. At this time, put the first sealing block into the side guard plate along the sealing sliding groove, and use the first sealing block to further fix the end of the steel bar. At this time, multiple steel bar meshes can be placed in the steel bar positioning groove to improve the practicability of the device. When the steel bar mesh is laid, cover the cover plate directly above the side guard plate. At this time, several second sealing blocks at the bottom of the cover plate move along the sealing sliding groove towards the end of the steel bar. Such a setting is beneficial in two aspects. On the one hand, it is beneficial to further position the end of the steel bar, so that the steel bar mesh maintains its initial position during the process of adding concrete, improving the product quality. On the other hand, it is beneficial to seal the steel bar positioning groove to prevent the flowing concrete from leaking along the steel bar positioning groove and improving the flatness of the side wall forming of the wall panel.

[0035] (5). In the present invention, by setting a rotating member, when the cover plate is installed, the connecting plate at the bottom of the cover plate drives the sliding sleeve to be sleeved on the rotating rod. At this time, the initial state of the moving block is at one end of the threaded groove close to the limiting block. Use a pneumatic wrench to rotate the interface bolt, and the interface bolt drives the rotating rod to rotate. At this time, the moving block drives the pressing plate at one end of the sliding sleeve to squeeze against the side wall of the side guard plate. Such a setting is beneficial to assisting the fasteners to fix the cover plate on the side wall of the side guard plate and strengthening the stability of the device structure.

[0036] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0070] The auxiliary fastener 32 includes a plurality of connecting plates 321 fixedly connected to the bottom of the cover plate 234. The side wall of the connecting plate 321 is fixedly connected with a telescopic rod 322. A compression spring 323 is sleeved on the end of the telescopic rod 322 far from the connecting plate 321. The end of the telescopic rod 322 far from the connecting plate 321 is fixedly connected with a sliding sleeve 324. The sliding sleeve 324 is slidably connected to the rotating rod 311. The end of the sliding sleeve 324 far from the telescopic rod 322 is fixedly connected with a pressing disc 325. The function of this component is to set the rotating member 31. When the cover plate 234 is installed, the connecting plate 321 at the bottom of the cover plate 234 drives the sliding sleeve 324 to be sleeved on the rotating rod 311. At this time, the initial state of the moving block 316 is located at one end of the threaded groove 314 close to the limiting block 315.

One end of the ejector post 331 away from the linkage rod 332 is fixedly connected to a top mold plate 333. The function of this component is to set the demolding member 33. When pouring concrete, the rotating rod 311 drives the moving block 316 to move. The moving block 316 drives the ejector post 331 at one end of the linkage rod 332 to slide outwards along the side guard plate 213 towards the inner cavity of the mold, providing a complete pouring space for the mold. When it is necessary to demold the solidified concrete, first loosen the fastening bolt 216. At this time, use a pneumatic hammer to drive the rotating rod 311 to rotate in the opposite direction. The moving block 316 moves towards one end close to the limit block 315. At this time, the linkage rod 332 drives the top mold plate 333 at one end of the ejector post 331 to be pressed against the side wall of the wall panel. The reaction force of the wall panel on the top mold plate 333 drives the entire sliding card slot 214 at both ends of the side guard plate 213 to slide outwards along the connecting convex block 212 on the fixed angle block 211. At this time, the inner wall of the side guard plate 213 and the side wall of the wall panel are demolded under the reaction force of the wall panel on the top mold plate 333, which improves the demolding efficiency of the wall panel; when the side guard plate 213 is separated from the side wall of the wall panel, remove the cover plate 234. At this time, the side guard plate 213 drives a plurality of seal blocks one 235 and seal blocks two 236 inside the side guard plate 213 to be separated from the inner wall of the wall panel. This setting avoids the adhesion of the seal blocks one 235 and the seal blocks two 236 to the side wall of the wall panel. At this time, by removing the cover plate 234, the cover plate 234 takes out a plurality of seal blocks two 236 inside the side guard plate 213. When the wall panel is taken out, the ends of the steel bars take out a plurality of seal blocks one 235 inside the seal chute 233, facilitating the recycling of the seal 23.

[0072] The usage method of the PC wall panel mold for precast concrete components includes the following steps:

[0073] Step 1: Assemble the mold. First, assemble the device. At this time, place the sliding card slots 214 at both ends of a plurality of side guard plates 213 on the connecting convex blocks 212 between the two fixed angle blocks 211, and push the side guard plates 213 inwards along the connecting convex blocks 212. At this time, insert the fastening bolts 216 into the inner part of the fixed chute one 215 and tighten them with the side walls of the fixed angle blocks 211. At this time, the pressing piece 218 on the fastening bolt 216 increases the contact area between the fastening bolt 216 and the side guard plate 213, so that the fixing effect between the side guard plate 213 and the fixed angle block 211 is better;

[0074] Step 2: Positioning and assembly. The construction workers place the ends of the steel bars laid in the inner cavity of the mold into the inner part of the steel bar positioning groove 232. At this time, the first sealing block 235 is placed into the inner part of the side guard plate 213 along the sealing sliding groove 233, and the first sealing block 235 is used to further fix the ends of the steel bars. At this time, multiple layers of steel bar meshes can be placed in the steel bar positioning groove 232 to improve the practicability of the device. When the steel bar meshes are laid, the cover plate 234 is covered directly above the side guard plate 213. At this time, several second sealing blocks 236 at the bottom of the cover plate 234 move along the sealing sliding groove 233 towards the ends of the steel bars.

[0075] Step 3: Rotational fixation. When the cover plate 234 is installed, the connecting plate 321 at the bottom of the cover plate 234 drives the sliding sleeve 324 to sleeved on the rotating rod 311. At this time, the initial state of the moving block 316 is located at one end of the threaded groove 314 close to the limiting block 315. Use an air gun to rotate the interface bolt 313, and the interface bolt 313 drives the rotating rod 311 to rotate. At this time, the moving block 316 drives the pressing plate 325 at one end of the sliding sleeve 324 to squeeze against the side wall of the side guard plate 213. This setting is beneficial to assist the fastener 32 to fix the cover plate 234 on the side wall of the side guard plate 213 and strengthen the stability of the device structure.

[0076] Step 4: Wall panel demoulding. When the concrete needs to solidify and be demoulded, first loosen the fastening bolt 216. At this time, use an air gun to drive the rotating rod 311 to rotate in the reverse direction, and the moving block 316 moves towards one end close to the limiting block 315. At this time, the linkage rod 332 drives the top die plate 333 at one end of the top material column 331 to squeeze against the side wall of the wall panel. The reaction force of the wall panel on the top die plate 333 drives the entire sliding card slot 214 at both ends of the side guard plate 213 to slide outwards along the connecting convex block 212 on the fixed angle block 211. At this time, the inner wall of the side guard plate 213 and the side wall of the wall panel are demoulded under the reaction force of the wall panel on the top die plate 333.

[0077] A specific application of this embodiment is as follows:

[0078] When using the PC wall panel mold of this concrete precast component, first assemble the device. At this time, the sliding card slots 214 at both ends of several side guard plates 213 are stuck on the connecting convex blocks 212 between the two fixed angle blocks 211, and the side guard plates 213 are pushed inwards along the connecting convex blocks 212. At this time, the fastening bolts 216 are inserted into the inner part of the first fixed sliding groove 215 and tightened with the side walls of the fixed angle blocks 211. At this time, the pressing pieces 218 on the fastening bolts 216 increase the contact area between the fastening bolts 216 and the side guard plates 213, so that the fixing effect between the side guard plates 213 and the fixed angle blocks 211 is better. In addition, the cross-section of the side guard plate 213 is in the shape of a "day", which is beneficial to replace the reinforcing ribs in the prior art and makes the structure of the side guard plate 213 stable.

[0079] By setting the seal 23, the construction worker puts the end of the steel bar laid in the inner cavity of the mold into the steel bar positioning groove 232. At this time, the first sealing block 235 is placed into the inner side guard plate 213 along the sealing chute 233, and the end of the steel bar is further fixed by the first sealing block 235. At this time, multiple layers of steel bar meshes can be placed in the steel bar positioning groove 232 to improve the practicability of the device. When the steel bar mesh is laid, the cover plate 234 is covered directly above the side guard plate 213. At this time, several second sealing blocks 236 at the bottom of the cover plate 234 move along the sealing chute 233 towards the end of the steel bar. Such a setting is beneficial in two aspects. On the one hand, it is conducive to further positioning the end of the steel bar, so that the steel bar mesh maintains its initial position during the addition of concrete, improving the product quality. On the other hand, it is beneficial to seal the steel bar positioning groove 232 to prevent the flowing concrete from leaking along the steel bar positioning groove 232, improving the flatness of the side wall forming of the wall panel. By setting the rotating member 31, when the cover plate 234 is installed, the connecting plate 321 at the bottom of the cover plate 234 drives the sliding sleeve 324 to be sleeved on the rotating rod 311. At this time, the initial state of the moving block 316 is located at one end of the threaded groove 314 close to the limiting block 315. Use a pneumatic wrench to rotate the interface bolt 313, and the interface bolt 313 drives the rotating rod 311 to rotate. At this time, the moving block 316 drives the pressing disc 325 at one end of the sliding sleeve 324 to squeeze against the side wall of the side guard plate 213. Such a setting is beneficial to assist the fastener 32 to fix the cover plate 234 on the side wall of the side guard plate 213, strengthening the stability of the device structure;

[0080] By setting the demolding member 33, when pouring concrete, the rotating rod 311 drives the moving block 316 to move. The moving block 316 drives the ejector post 331 at one end of the linkage rod 332 to slide outward along the side guard plate 213 towards the inner cavity of the mold, providing a complete pouring space for the mold. When demolding is required after the concrete has solidified, first loosen the fastening bolt 216. At this time, use a pneumatic hammer to drive the rotating rod 311 to rotate in the reverse direction, and the moving block 316 moves towards the end close to the limit block 315. At this time, the linkage rod 332 drives the top mold plate 333 at one end of the ejector post 331 to be pressed against the side wall of the wall panel. The reaction force of the wall panel on the top mold plate 333 drives the entire sliding card slots 214 at both ends of the side guard plate 213 to slide outward along the connecting convex blocks 212 on the fixed angle block 211. At this time, the inner wall of the side guard plate 213 and the side wall of the wall panel are demolded under the reaction force of the wall panel on the top mold plate 333, which improves the demolding efficiency of the wall panel. When the side guard plate 213 is separated from the side wall of the wall panel, remove the cover plate 234. At this time, the side guard plate 213 drives a number of seal blocks one 235 and seal blocks two 236 inside the side guard plate 213 to be separated from the inner wall of the wall panel. This setting avoids the adhesion of the seal blocks one 235 and the seal blocks two 236 to the side wall of the wall panel. At this time, by removing the cover plate 234, the cover plate 234 brings out a number of seal blocks two 236 inside the side guard plate 213. When the wall panel is taken out, the ends of the steel bars bring out a number of seal blocks one 235 inside the seal chute 233, facilitating the recycling of the seal 23.
