Description

Technical Field

[0001] The present invention belongs to the technical field of prefabrication of concrete composite slabs, and specifically relates to a composite slab mold that can be quickly assembled and demolded. Background Art

[0002] A composite slab is an assembled monolithic reinforced concrete slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. It belongs to a horizontal structural member. Usually, components such as steel bar meshes are reserved in the precast slab. The steel bar mesh can not only enhance the stiffness of the precast slab but also better enable the concrete to be poured during the subsequent construction of the cast-in-place layer. That is, after the precast slab is transported to the construction site and installed in place, an additional steel bar frame is laid on the precast slab, and then concrete is poured to form the cast-in-place layer. Finally, the precast slab and the cast-in-place layer form a whole (i.e., the composite slab), thus forming a complete load-bearing member.

[0003] When producing the precast slab used in the composite slab, first, the mixed concrete is transported into the mold by pumping or hoisting, and the layered pouring method is adopted to control the thickness of each layer of pouring. A vibrating device is used to ensure the compactness of the concrete and avoid defects such as honeycombing and pockmarks.

[0004] In the current prior art, before the concrete is poured in layers, the steel bar mesh needs to be placed in the mold in advance. Since the steel bar mesh is usually divided into upper and lower layers and welded together longitudinally and transversely, after the steel bar mesh is placed in the mold, the lower steel bars will be in close contact with the bottom of the placement groove of the mold, resulting in a large gap above the placement groove, and the upper steel bars will be in a position slightly below the middle of the placement groove, resulting in a larger gap. At this time, when the concrete is poured in layers, some of the concrete will flow out from the gap between the placement groove of the mold and the steel bar mesh. In order to avoid cracks and other situations at the four sides of the precast slab under the action of hammer knocking, at this time, the mold needs to be naturally demolded from the precast slab. When the concrete dries, it will cause the steel bar mesh and the four sides of the precast slab to stick to the mold, and the mold cannot be quickly removed, and the removal efficiency is too low; Moreover, after the concrete is poured in layers, when the vibrating device is used to compact the concrete, at this time, the concrete is more likely to flow out from the gap under the action of the vibration force, which will reduce the utilization rate of the concrete. Therefore, the present invention provides a composite slab mold that can be quickly assembled and demolded. Summary of the Invention

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] As Figures 5 to 9 shown, a laminated board mold capable of rapid assembly and demolding according to an embodiment of the present invention includes two horizontal molds 1, and a pair of vertical molds 2 are slidably clamped on opposite sides of the two horizontal molds 1. Placement grooves are respectively provided inside the horizontal molds 1 and the vertical molds 2, and horizontal mold auxiliary components 5 and vertical mold auxiliary components 6 for preventing concrete from flowing out are respectively arranged in the placement grooves opened by the horizontal molds 1 and the vertical molds 2; The horizontal mold auxiliary component 5 includes a cover plate 501 clamped above the horizontal mold 1, and an insertion block 502 is fixedly connected below the cover plate 501. The cover plate 501 is clamped with the horizontal mold 1 through the insertion block 502; The vertical mold auxiliary component 6 includes a second slider 601 slidably installed inside the placement groove of the vertical mold 2. An articulated slide bar 602 is hinged above the second slider 601, and both ends of the articulated slide bar 602 are in sliding contact with a slide plate 603, and an inclined groove is provided inside the slide plate 603.

[0022] In the present invention, it is considered that when concrete is poured in layers inside a mold, in order to avoid the position deviation of the steel mesh during the concrete pouring process, which may affect the final forming quality, the four sides of the steel mesh, which are welded together in a staggered manner up and down, need to be placed inside multiple groups of placement grooves opened in the mold to improve the stability of the steel mesh during the concrete pouring. However, when the steel mesh is placed inside the placement groove, the lower layer of steel bars will be in close contact with the bottom of the placement groove, and a large number of voids will be formed above. When the upper layer of steel bars is placed in the placement groove, due to the height of the lower layer of steel bars, the upper layer of steel bars will be located slightly below the middle of the placement groove, with voids existing both above and below the placement groove. At this time, when the concrete is poured in layers, it will flow out from the position of the placement groove inside the mold, and the concrete that has flowed out will dry and solidify, causing the four sides of the steel mesh, as well as the formed precast slab and the mold, to stick together, which is not conducive to the demolding process; Therefore, a mold is formed by two sets of transverse molds 1 and two sets of longitudinal molds 2. By inserting one end of the longitudinal mold 2 into one side of the transverse mold 1, the two can be quickly connected together to form the prototype of the mold, which is convenient for subsequent adjustment of the size of the precast slab. Moreover, when the steel mesh is placed inside the placement groove opened in the transverse mold 1, the upper layer of steel bars on the steel mesh will be located slightly below the middle of the placement groove. At this time, the insertion blocks 502 at both ends of the cover plate 501 are inserted into the transverse mold 1, so that the lower end of the insertion block 502 contacts the surface of the steel bars, making the upper part of the placement groove inside the transverse mold 1 in a "sealed" state, which can effectively isolate the concrete inside the mold and prevent the concrete from flowing out; It should be noted that when the steel bars are placed inside the placement groove in the longitudinal mold 2, the lower layer of steel bars will push the second slider 601 to slide downward inside the longitudinal mold 2 under the action of gravity, so that the upper end of the second slider 601 always contacts the surface of the lower layer of steel bars. And when the second slider 601 moves downward under the action of the gravity of the steel bars, it will drive the articulated slide bar 602 to move downward. Since both ends of the articulated slide bar 602 are inserted into the inclined grooves opened inside the slide plate 603, the downward movement of the articulated slide bar 602 can drive the two slide plates 603 to move relative to each other, isolating the void above the lower layer of steel bars and the placement groove, making the placement groove inside the longitudinal mold 2 also in a "sealed" state, which can also isolate the concrete and prevent the concrete from flowing out from the placement groove opened inside the longitudinal mold 2. By completely isolating the concrete inside the mold, whether it is pouring the concrete in layers or performing the vibration work later, it can effectively prevent the concrete from drying after flowing out and affecting the demolding efficiency between the mold and the precast slab, enabling the mold to be quickly separated from the formed precast slab, with high working efficiency.

[0023] Such as Figures 5 to 6As shown, the horizontal mold auxiliary component 5 further includes a first slider 503 slidably disposed inside the horizontal mold 1. Return springs are provided at the bottoms of both the first slider 503 and the second slider 601. A first anti-slip pad 504 is detachably connected above the first slider 503, and a second anti-slip pad 605 is detachably connected above the second slider 601. The inner side surface of the slide plate 603 is slidably connected to the second slider 601, and the slide plate 603 is slidably connected to the horizontal mold 1.

[0024] During operation, when the steel bars are placed in the placement groove inside the horizontal mold 1, at this time, the first slider 503 will move downward under the action of gravity, and it can also make the lower surface of the steel bars continuously contact with the first slider 503. And by providing return springs under both the first slider 503 and the second slider 601, when the steel bar mesh is placed, the impact force generated by placing the steel bar mesh can be buffered by the acting force of multiple groups of return springs, avoiding the direct contact between the steel bar mesh and the placement grooves opened inside the horizontal mold 1 and the vertical mold 2, which can protect the horizontal mold 1 and the vertical mold 2 to a certain extent, avoid deformation after long-term use of the two, and improve the overall service life of the mold. It should be noted that since the upper-layer steel bars will be in the middle and lower position of the placement groove inside the horizontal mold 1 after being placed, at this time, even if the first slider 503 moves downward under the gravity of the steel bars, through the reverse acting force of the return spring below the first slider 503, the surface of the first slider 503 can always be in contact with the surface of the steel bars, isolating the gap between the upper-layer steel bars and below the placement groove. And it should be noted that since the insert block 502 and the cover plate 501 are fixedly connected, at this time, the two are produced as a whole. According to actual needs, the actual length of the insert block 502 fixed on the cover plate 501 can be set in multiple specifications to adapt to the height when steel bars of different sizes are placed inside the placement groove, so that the lower part of the insert block 502 will always be in contact with the upper surface of the steel bars. In actual use, when the length of the insert block 502 is greater than the height of the steel bars placed inside the placement groove, at this time, the cover plate 501 and the insert block 502 can be replaced together, so that the length of the insert block 502 inserted into the placement groove can be freely adjusted. When the cover plate 501 is inserted into the horizontal mold 1, at this time, there may be a gap between the cover plate 501 and the upper surface of the horizontal mold 1, but the lower surface of the insert block 502 will also always be in contact with the upper surface of the steel bars, isolating the gap between the upper-layer steel bars and above the placement groove, isolating the gap between the upper-layer steel bars and the placement groove position inside the horizontal mold 1, and making the placement groove inside the horizontal mold 1 also form a "sealed" state, which can comprehensively inhibit the outflow of concrete and improve the tightness of concrete pouring or subsequent vibration work, thereby improving the effect of subsequent removal of the mold.

[0025] Such as Figures 1 to 4As shown in the figure, holes are provided at both ends of the longitudinal mold 2, and a connecting rod 4 is clamped inside the holes. The transverse mold 1 is sleeved on the surface of the connecting rod 4. Connecting components 3 for improving the connection stability of the connecting rod 4 are arranged at both ends of the transverse mold 1. The connecting component 3 includes a threaded rod 301 threadedly connected to the transverse mold 1. The lower end of the threaded rod 301 is rotatably connected to a top plate 302. A triangular block 303 is fixedly connected to the lower end of the top plate 302. A swinging clamping plate 304 for clamping the surface of the connecting rod 4 is in sliding contact with the inner inclined surface of the triangular block 303.

[0026] The present invention also takes into account that when both ends of the longitudinal mold 2 are inserted into the inside of the transverse mold 1, since the concrete is poured on the steel mesh by the method of layered pouring, at this time, the concrete will be poured inside the mold to a certain height at intervals for a period of time. However, relying only on one end of the longitudinal mold 2 to be slidably clamped on one side of the transverse mold 1, the method of pouring and vibrating the concrete multiple times may cause the longitudinal mold 2 to slide outwards from one side of the transverse mold 1, resulting in dimensional deviation and affecting the final forming specifications of the precast slab. Therefore, when both ends of the longitudinal mold 2 are slidably inserted into one side of the transverse mold 1, after the final size of the precast slab is determined, at this time, the connecting rod 4 is inserted into the holes provided in the longitudinal mold 2 through the transverse mold 1, and then the threaded rod 301 is rotated downward by an electric wrench or the like. The movement of the threaded rod 301 drives the top plate 302 to move downward, and the movement of the top plate 302 drives the triangular block 303 to move downward. Since the inner inclined surface of the triangular block 303 is in sliding contact with the swinging clamping plate 304, at this time, the downward movement of the triangular block 303 will cause the two swinging clamping plates 304 to swing around the pin shaft below, so as to closely adhere to the protrusions on the surface of the connecting rod 4, and the connecting rod 4 can be clamped. On the one hand, it can improve the connection stability between the transverse mold 1 and the longitudinal mold 2, and on the other hand, it can fix the position of the connecting rod 4, avoiding the position deviation of the transverse mold 1 and the longitudinal mold 2 due to the impact force generated during multiple concrete pourings, and effectively improving the stability of the mold during concrete pouring. It should be noted that by inserting the longitudinal mold 2 into one side of the transverse mold 1, and first connecting the two together through the connecting rod 4 to determine the final forming size of the precast slab, and finally, the movement of the connecting component 3 can further improve the connection stability between the transverse mold 1 and the longitudinal mold 2, which can not only improve the stability of the precast slab during pouring and forming, but also enable rapid assembly, determine the final forming size of the precast slab, and improve the assembly efficiency.

[0027] As Figures 3 to 4 shown, the side surface of the top plate 302 is in sliding connection with the inside of the transverse mold 1. The bottom of the swinging clamping plate 304 is rotatably connected to the transverse mold 1 through a pin shaft. The connecting component 3 is located inside the working chambers provided at both ends of the transverse mold 1. A tension spring is arranged between the swinging clamping plate 304 and the inner side wall of the working chamber.

[0028] During operation, when the triangular block 303 squeezes the two groups of swing clamping plates 304 through the inclined surface, causing the swing clamping plates 304 to swing around the pin shaft to clamp the connecting rod 4, at this time, by arranging a tension spring between the swing clamping plate 304 and the inner wall of the working bin, when the swing clamping plate 304 swings towards the position of the connecting rod 4, the tension spring can be pulled. When the triangular block 303 no longer applies a squeezing force to the swing clamping plate 304, the upper end of the swing clamping plate 304 will always contact the inner inclined surface of the triangular block 303 under the rebound force of the tension spring. When adjusting the position of the connecting rod 4 subsequently, it is convenient for the connecting rod 4 to be inserted into the interiors of the horizontal mold 1 and the vertical mold 2, which can effectively improve the assembly efficiency between the horizontal mold 1 and the vertical mold 2.

[0029] As Figures 1 to 2 shown, several groups of holes are also opened on the surface of the horizontal mold 1, and the diameters of these holes are the same as those of the holes opened at both ends of the vertical mold 2. The placement grooves inside the horizontal mold 1 and the vertical mold 2 are opened in a U shape. Both the horizontal mold 1 and the vertical mold 2 are made of materials with high strength and high wear resistance.

[0030] During operation, when adjusting the final forming size of the precast slab, at this time, only the position of the vertical mold 2 needs to be adjusted. By rotating the threaded rod 301 in the reverse direction to make it move upward, the swing clamping plate 304 will swing in the reverse direction under the action of the tension spring. At this time, the connecting rod 4 is pulled out from the holes opened in the vertical mold 2 and the horizontal mold 1, the holes opened inside the vertical mold 2 and the horizontal mold 1 are repositioned, and then the connecting rod 4 is inserted again, which can effectively improve the connection stability between the horizontal mold 1 and the vertical mold 2; It should be noted that since the connecting component 3 is only arranged inside the working bins opened at both ends of the horizontal mold 1, when adjusting the position where the connecting rod 4 is inserted into the horizontal mold 1 and the vertical mold 2, only the contact distance between the connecting rod 4 and one of the two groups of swing clamping plates 304 is adjusted. As Figure 4 shown, that is, if the connecting rod 4 approaches the right group of swing clamping plates 304, it will move away from the position of the left group of swing clamping plates 304, so that one of the two groups of swing clamping plates 304 always contacts the surface of the connecting rod 4, thereby enabling fine adjustment of the final forming size of the precast slab and improving the dimensional accuracy of the final forming of the precast slab. When precast slabs of different sizes need to be produced, the horizontal mold 1 and the vertical mold 2 need to be replaced to adjust the production sizes of different precast slabs.

[0031] As Figures 1 to 2 shown, the sliding position of the vertical mold 2 on one side of the horizontal mold 1 is arranged in a T shape. A T-shaped groove for sliding cooperation with the vertical mold 2 is opened on one side of the horizontal mold 1. The cross-sections of both the horizontal mold 1 and the vertical mold 2 are L-shaped structures, and multiple rib plates are arranged on both the horizontal mold 1 and the vertical mold 2.

[0032] During operation, when the longitudinal mold 2 is clamped inside the transverse mold 1, the T-shaped setting at one end of the longitudinal mold 2 is inserted into the T-shaped groove opened on one side of the transverse mold 1, enabling the rapid assembly of the transverse mold 1 and the longitudinal mold 2, thereby improving the overall assembly efficiency of the mold. Moreover, it can quickly fine-tune the final forming size of the precast slab, further improving the forming quality in the later stage. Additionally, by arranging multiple groups of rib plates on the surfaces of the transverse mold 1 and the longitudinal mold 2, the stability of the transverse mold 1 and the longitudinal mold 2 after being impacted by concrete can be further enhanced, thus improving the quality of the final formed precast slab.

[0033] As Figures 3 to 4 shown, an arc-shaped groove is provided at the position of the swing clamping plate 304 close to the axis of the connecting rod 4. The width of the triangular block 303 is greater than the width of the lower swing clamping plate 304. The upper part of the swing clamping plate 304 is arc-shaped. Both the triangular block 303 and the swing clamping plate 304 are made of materials with high wear resistance.

[0034] During operation, since there are protrusions on the surface of the connecting rod 4 and the connecting rod 4 is integrally "cylindrical", an arc-shaped groove is provided on one side of the swing clamping plate 304. When the swing clamping plate 304 clamps and fixes the connecting rod 4, the contact area between the swing clamping plate 304 and the connecting rod 4 will increase at this time, and the frictional force will increase, thereby improving the clamping effect of the swing clamping plate 304 on the connecting rod 4. It should be noted that when the position of the connecting rod 4 is slightly adjusted, the connecting rod 4 will approach the position of one of the swing clamping plates 304 at this time. When the triangular block 303 descends to squeeze the swing clamping plate 304, by setting the upper part of the swing clamping plate 304 to be arc-shaped, it can better make the swing clamping plate 304 contact with the inclined surface of the triangular block 303, thereby better pushing the swing clamping plate 304 to clamp and fix the connecting rod 4. Moreover, since the width of the triangular block 303 is greater than the width of the swing clamping plate 304, it can be avoided that when the triangular block 303 squeezes the swing clamping plate 304, the swing clamping plate 304 is unevenly stressed and cannot fully clamp the connecting rod 4, and the clamping effect on the connecting rod 4 can be effectively improved, enabling the transverse mold 1 and the longitudinal mold 2 to be fully connected.

[0035] As Figures 7 to 9 shown, four groups of sliding plates 603 are slidably arranged inside the longitudinal mold 2. Rubber partitions 604 in close contact with the surface of the steel bars are fixedly connected below the four groups of sliding plates 603. The inclined grooves opened inside the two horizontally arranged sliding plates 603 are mirror-image openings.

[0036] During operation, when the steel bar mesh is placed inside the placement groove and contacts the second slider 601, before the second slider 601 moves downward under the action of gravity, its upper end is located at the top of the longitudinal mold 2. When the second slider 601 moves downward, it continuously pulls the slide plate 603 closer to the inner middle position through two groups of articulated sliding rods 602. While the slide plate 603 is moving, it can drive multiple groups of rubber partitions 604 to move synchronously, enabling the rubber partitions 604 to fully contact the surface of the steel bars, which can further improve the sealing performance of the placement groove and prevent the concrete from flowing out. Moreover, due to the first anti-slip pad 504 provided above the first slider 503 and the second anti-slip pad 605 provided above the second slider 601, it can provide effective stability for the steel bar mesh placed inside the placement groove, prevent the concrete from shaking during the pouring process, affect the final forming quality of the precast slab, and effectively isolate the concrete, which can effectively improve the subsequent demoulding efficiency; Moreover, since the second slider 601 is hinged to the articulated sliding rod 602, when the second slider 601 drives the articulated sliding rod 602 at this time, the articulated sliding rod 602 will be limited by the second slider 601, enabling the articulated sliding rod 602 itself to rotate, so that when the articulated sliding rod 602 moves up and down to push the two slide plates 603, the sliding is more smooth, and the situation of jamming when the articulated sliding rod 602 slides in the inclined groove opened on the slide plate 603 can be avoided.

[0037] As Figures 3 to 4 shown, the rotation of the threaded rod 301 drives the top plate 302 to move up and down. The top plate 302 drives the swing clamping plate 304 to swing around the pin shaft through the inclined surface of the triangular block 303. One end of the spring stretched by one side of the swing clamping plate 304 is fixedly connected to the working bin.

[0038] During operation, the positive and reverse rotation of the threaded rod 301 drives the top plate 302 to move up and down. The up and down movement of the top plate 302 drives the triangular block 303 to clamp the swing clamping plate 304, which can effectively improve the stability after the connecting rod 4 is inserted into the holes opened in the longitudinal mold 2 and the transverse mold 1, so that the transverse mold 1 and the longitudinal mold 2 can be stably connected, and can be quickly disassembled. It not only has high assembly efficiency, but also is convenient for disassembling the transverse mold 1 and the longitudinal mold 2 later, and will not cause damage to the periphery of the formed precast slab, and can protect it.

[0039] As Figures 5 to 6 shown, multiple insertion blocks 502 provided below the cover plate 501 are made of wear-resistant materials. The insertion blocks 502 at both ends of the cover plate 501 are arranged in a T shape, and a T-shaped groove matching with them is opened inside the transverse mold 1 directly below the insertion blocks 502.

[0040] During operation, after the steel bar mesh is placed inside the placement groove, the insertion blocks 502 at both ends of the cover plate 501 will be inserted into the inside of the horizontal mold 1. This can not only further limit and fix the steel bar mesh, but also effectively prevent the concrete from flowing out. Moreover, since the insertion blocks 502 at both ends of the cover plate 501 are T-shaped and the inside of the horizontal mold 1 is provided with a matching T-shaped groove, it can further improve the stability of the cover plate 501 when it is integrally inserted into the horizontal mold 1 during operation.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
