Description

Technical Field

[0001] The present invention relates to the technical field of construction engineering, and specifically to a modular adjustable combined elastic cushion suitable for stacking and transporting precast components. Background Art

[0002] At present, wooden cushions are generally used for stacking and transporting precast components in China. In order to improve efficiency in precast factories, when stacking and transporting precast components, precast components with similar size specifications are often stacked in multiple layers. To reduce the deformation, cracking, and damage caused by the extrusion and collision of precast components, the precast components generally do not directly contact each other, and wooden cushions are arranged between the components. At the same time, in order to reduce the internal stress of the precast components, the cushions are generally arranged in multiple rows and columns in a horizontal and vertical manner. Therefore, in one plane, the number of cushions is relatively large. At the same time, in order to directly conduct the weight of the upper components in the multi-layer stacking through the cushions to the bottom, it is required that the cushions be aligned both horizontally and vertically. Due to these requirements for cushion arrangement, a large number of wooden cushions are needed during stacking and transportation.

[0003] Due to the differences in the characteristics of wood and the processing dimensions of different batches of wooden cushions, the thicknesses of the cushions are not the same. It is impossible to ensure that the top surfaces of the cushions in one plane are completely flat. When the upper precast components are stacked, there will be a situation where the lower part of the components is void at some local positions, and the stress at some local positions increases, increasing the risk of component deformation and cracking. Secondly, each wooden cushion is placed separately, so the efficiency is relatively low, and it is also difficult to arrange them horizontally and vertically. When the components are stacked in multiple layers, the mutual stagger of the wooden cushions is more obvious, which is not conducive to directly transferring the weight of the upper precast components through the cushions to the bottom (shelf), increasing the risk of component deformation and cracking.

[0004] In order to solve the above problems, this case is thus born. Summary of the Invention

[0005] (I) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides a modular adjustable combined elastic cushion suitable for stacking and transporting precast components, and solves the problems raised in the above background art.

[0007] (II) Technical Solutions

[0008] To achieve the above objectives, the present invention is realized through the following technical solutions: A modular adjustable combined elastic cushion suitable for stacking and transporting precast components, including a combined elastic cushion. The combined elastic cushion includes a longitudinally continuous combined connecting plate at the upper part and independent cushions at the lower part. The distance between adjacent two combined elastic cushions can be correspondingly adjusted. Among them, the longitudinally continuous combined connecting plate at the upper part includes an internally placed longitudinally continuous connecting steel plate and an externally wrapped elastic rubber body. The longitudinally continuous connecting steel plate and the independent cushions are fixed in position through a connecting body.

[0009] As a preferred solution, further, the continuous connecting steel plate is made of iron, and the independent cushion block includes an internal magnet and a flexible buffer body, wherein the magnet serves as the connecting body between the two, and the flexible buffer body wraps the magnet.

[0010] As a preferred solution, further, the connecting body is an embedded nut built into the continuous connecting steel plate, wherein the continuous connecting steel plate reserves an embedded nut position according to a preset size, and the independent cushion block includes an internal screw rod and a flexible buffer body at the outsourcing position, and the internal screw rod can be bolt-connected to the embedded nut.

[0011] As a preferred solution, further, the head of the screw rod is provided with threads, and the tail adopts any one of a dovetail shape, a reinforcing steel bar welded at the tail, and a reinforcing steel plate welding weld at the tail.

[0012] As a preferred solution, further, the continuous combined connecting plate is hollow and contains a plurality of continuously adjustable connecting steel plates. The number of continuous connecting steel plates is the same as the number of columns of independent cushion blocks in the longitudinal direction. The continuous connecting steel plate is made of iron, and magnets are provided inside the independent cushion blocks, and one is arranged at each of the upper and lower parts.

[0013] As a preferred solution, further, a horizontally penetrating long groove is formed on the continuous combined connecting plate, and a displacement block is connected to each continuous connecting steel plate. The width dimension of the displacement block is smaller than the width dimension of the long groove.

[0014] As a preferred solution, for the modular adjusted combined elastic cushion blocks suitable for stacking and transporting precast components, the stacking steps are as follows: S1. Through the displacement blocks connected to each continuous connecting steel plate, the adjacent positions of the continuous connecting steel plates are pre-adjusted to a preset spacing, and the corresponding independent cushion blocks are placed on the same vertical line by means of magnets to complete the stacking of the bottom layer; S2. According to the positions of the continuous connecting steel plates at the bottom layer, the corresponding independent cushion blocks are first stacked onto the relatively lower continuous combined connecting plate to a preset position and are flush with the positions of the independent cushion blocks below; S3. The positions of the continuous connecting steel plates placed in the continuous combined connecting plates stacked relatively above can be determined with the help of the independent cushion blocks stacked on the lower side in step S2, and stacked upwards accordingly. The stacked independent cushion blocks are always accurately positioned on the same straight line, and finally they are disassembled and assembled onto the precast components of the upper layer.

[0015] As a preferred solution, further, the flexible buffer body and the elastic rubber body are made of elastic materials such as rubber or plastic.

[0016] (III) Beneficial effects

[0017] After adopting the above technical solution, a modular adjustable combined elastic cushion suitable for stacking and transporting precast components provided by the present invention has the following beneficial effects compared with the prior art:

[0018] 1. This combined elastic cushion has better elasticity compared with traditional wooden cushions. During the stacking and transportation of components, it can better absorb the concentrated stress caused by vibration and impact, reducing component deformation, cracking and damage. Moreover, the elastic material in this combined elastic cushion can be waste rubber, plastic, etc., especially waste automobile tires. It can achieve the recycling of waste, reducing environmental pollution and procurement costs.

[0019] 2. The setting of this combined elastic cushion can flexibly adjust the combination method according to the length modulus size, so that the multi-layer cushions are always on the same vertical line to be applicable to precast components of different sizes and different external profiles, and are placed in rows. Compared with the traditional method where the upper and lower layers need to be separately adjusted and placed to the corresponding positions, the efficiency is higher, and the time cost and labor cost are both lower.

Specific embodiments

[0032] In order to make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the following further elaborates on the present invention in detail with reference to specific embodiments and the accompanying drawings.

[0033] Please refer to the attached Figure 1 and the attached Figure 2 As shown, it shows a schematic diagram of the function of the combined elastic cushion block 3 of the present invention when multiple precast members 1 are stacked. Among them, after the precast member 1 is produced in the factory and before it is transported to the construction site for installation, the combined elastic cushion block 3 of this case can be used to achieve the multi-layer stacking and transportation of the precast member 1.

[0034] For the setting of the combined elastic cushion block 3 in this embodiment, it is necessary to determine the number and spacing of the lower independent cushion blocks 5 according to the different sizes and external contour of the precast member 1, such as the stiffeners and corbels of the precast member 1. The spacing of the combined elastic cushion block 3 is set according to the stacking and transportation requirements of the precast member 1 to ensure that the precast members 1 do not directly contact each other, and at the same time ensure that each position can be evenly stressed.

[0035] When the precast member 1 is stacked and transported, the cushion blocks are arranged in a horizontal and vertical manner with multiple rows and columns. The number of cushion blocks in one layer plane is relatively large. When stacked in multiple layers, each cushion block is placed separately, and the efficiency is relatively low. Using the combined elastic cushion block 3 of this case to be placed in groups and rows has a higher efficiency and saves time and labor costs.

[0036] Embodiment 1

[0037] Attached Figure 3 and attached Figure 4 As shown, it shows a schematic diagram of the composition and structural details of the combined elastic cushion block 3 of the present invention. The combined elastic cushion block 3 of this case is composed of two parts: the upper full-length combined connecting plate 4 and the lower independent cushion block 5, and the two are connected and quickly positioned by the attraction of the magnet 8.

[0038] Among them, the upper continuous combined connecting plate 4 includes an internal continuous connecting steel plate 7 and an elastic rubber body 6. The internal continuous connecting steel plate 7 provides a magnetic attraction bonding surface for the connection between the upper continuous combined connecting plate 4 and the lower independent cushion block 5 when they are connected.

[0039] The internal continuous connecting steel plate 7 is completely wrapped in the elastic rubber body 6, which increases the durability of the internal continuous connecting steel plate 7. At the same time, when it contacts the bottom of the upper precast member 1, the elastic rubber body 6 also plays a good protective role for the precast member 1.

[0040] Among them, the lower independent cushion block 5 includes an internal magnet 8 and a flexible buffer body 17. The internal magnet 8 provides the magnetic attraction of the magnet 8 when the lower independent cushion block 5 is connected to the upper continuous combined connecting plate 4. The internal magnet 8 is completely wrapped in the flexible buffer body 17, which increases the durability of the internal magnet 8. The flexible buffer body 17 is the main energy-absorbing structure. When the precast member 1 is stacked and transported, it can better absorb the concentrated stress caused by vibration and impact, and reduce the deformation, cracking and damage of the precast member 1.

[0041] The spacing dimension of the independent cushion blocks 5 is the main dimension that can be adjusted by the combined elastic cushion block 3. The number and spacing of the lower independent cushion blocks 5 can be determined according to the stiffeners, corbels and other convex parts 2 of the precast member 1 with the outer contour, so as to ensure that the precast members 1 do not directly contact each other. The precast members 1 are buffered by the combined elastic cushion block 3 in this case, ensuring that each position can be evenly stressed.

[0042] The flexible buffer body 17 and the elastic rubber body 6 are mainly made of elastic materials such as rubber and plastic, and waste rubber and plastic can also be used, especially waste automobile tires. It can achieve the recycling of waste, reduce environmental pollution and lower the procurement cost.

[0043] Embodiment 2

[0044] Please refer to the attached Figure 3 and attached Figure 5 As shown, it shows a schematic diagram of the composition and structural details of the combined elastic cushion block 3 of the present invention. The combined elastic cushion block 3 of this case is composed of an upper continuous combined connecting plate 4 and a lower independent cushion block 5, and the two are connected by bolts.

[0045] Among them, the upper continuous combined connecting plate 4 includes an internal continuous connecting steel plate 7 and an elastic rubber body 6. The continuous connecting steel plate 7 is embedded with nuts. The continuous connecting steel plate 7 reserves embedded nuts 11 according to the length modulus dimension. The embedded nuts 11 are bolt-connected to the internal screw rods 12 of the lower independent cushion block 5, and the connection position is flexibly adjustable according to the length modulus, better adapting to the different sizes and different outer contours of the precast member 1.

[0046] Among them, the lower independent cushion block 5 includes an internal screw rod 12 and a flexible buffer body 17. The internal screw rod 12 and the embedded nut 11 provide a reliable bolt connection for connecting the lower independent cushion block 5 and the upper full-length combined connecting plate 4. The internal screw rod 12 is completely wrapped in the flexible buffer body 17, increasing the durability of the internal screw rod 12. The flexible buffer body 17 is the main energy-absorbing structure. When the precast member 1 is stacked and transported, it can better absorb the concentrated stress caused by vibration and impact, reducing the deformation, cracking and damage of the precast member 1.

[0047] Among them, the modular length is the main dimension that the combined elastic cushion block 3 can adjust. The number and spacing of the lower independent cushion blocks 5 can be determined according to the external convex parts 2 such as the stiffeners and corbels of the precast member 1 with the contour, ensuring that the precast members 1 do not directly contact each other. The precast members 1 are buffered by the combined elastic cushion blocks 3 in this case, ensuring that each position can be evenly stressed.

[0048] The flexible buffer body 17 and the elastic rubber body 6 are mainly elastic materials such as rubber and plastic, and waste rubber and plastic can also be used, especially waste automobile tires. It can achieve the recycling of waste, reducing environmental pollution and procurement costs at the same time.

[0049] Please refer to the attached instruction Figure 6 As shown, it shows a schematic cross-sectional view of the upper full-length combined connecting plate 4 of the combined elastic cushion block 3 of the present invention. The upper full-length combined connecting plate 4 includes an internal full-length connecting steel plate 7 and an elastic rubber body 6. The internal full-length connecting steel plate 7 includes a full-length connecting steel plate 7 and an embedded nut 11. The upper ends of the full-length connecting steel plate 7 and the embedded nut 11 are wrapped in the elastic rubber body 6, increasing the durability of the full-length connecting steel plate 7 and the embedded nut 11. At the same time, when contacting the bottom of the precast member 1, the elastic rubber body 6 also plays a good protective role for the precast member 1. The lower end of the embedded nut 11 is flush with the elastic material of the outer elastic rubber body 6, facilitating the internal embedded screw rod 12 of the lower independent cushion block 5 to be screwed in for reliable bolt connection.

[0050] Please refer to the attached instruction Figure 7 As shown, it shows a large-scale schematic view of the internal full-length connecting steel plate 7 in the upper full-length combined connecting plate 4 of the combined elastic cushion block 3 of the present invention. The full-length connecting steel plate 7 reserves the embedded nut 11 according to the length modulus dimension. The embedded nut 11 and the internal screw rod 12 of the lower independent cushion block 5 are bolt-connected, and the connection position is flexibly adjustable according to the length modulus, better adapting to the different sizes and contours of the precast member 1.

[0051] Please refer to the attached instruction Figure 8As shown, it presents a detailed schematic diagram of various built-in screws 12 in the independent cushion block 5 at the lower part of the combined elastic cushion block 3 of the present invention. For the built-in screws 12 embedded in the independent cushion block 5 at the lower part to have a reliable connection with the embedded nuts 11 inside the continuous combined connecting plate 4 at the upper part, threads are provided at the heads of the screws; at the same time, to ensure a reliable connection between the built-in screws 12 and the surrounding flexible buffer 17. Three methods are often used at the tails of the screws. The first is that the tail is in the shape of a dovetail; the second is that a reinforcing bar 13 is provided at the tail of the screw, that is, the reinforcing bar 13 is welded to the tail of the screw, and the reinforcing bar 13 and the tail of the screw are connected by a welding seam 14; the third is that a reinforcing steel plate 15 is provided at the tail of the screw and the reinforcing steel plate 15 is welded to the tail of the screw, and the reinforcing steel plate 15 and the tail of the screw are connected by a welding seam 14.

[0052] Embodiment III

[0053] In the actual application process, the process of determining the placement position of the independent cushion block 5 is relatively complex, which makes it difficult for multiple layers of independent cushion blocks 5 between vertically stacked precast slabs to be on the same vertical line due to blind spots (for the treatment of the prior art, reference can be made to the comparative document with the publication number CN113353633B, named "A cushion wood positioning device for a truss reinforced concrete precast slab and its usage method"). This embodiment can achieve the alignment placement of the independent cushion blocks 5 between different precast component layers without the need for an external positioning device.

[0054] See the appendix Figure 9 - 10 As shown, the continuous combined connecting plate 4 is hollow and contains multiple continuously connected steel plates 7 that can be movably adjusted (the steel plates contain a certain iron content), and the number of the continuously connected steel plates 7 is the same as the number of columns of the longitudinal independent cushion blocks 5. The independent cushion blocks 5 at the bottom are quickly and passively positioned accurately on the same straight line through the positions corresponding to the continuously connected steel plates 7, and there is no need to use an external positioning device for the position of the independent cushion blocks 5.

[0055] Secondly, a horizontally penetrating long groove 9 is opened on the continuous combined connecting plate 4, and a displacement block 16 is connected to each continuously connected steel plate 7. The width dimension of the displacement block 16 is smaller than the width dimension of the long groove 9, so that the distance between the continuously connected steel plates 7 can be pre-adjusted to adapt to the modulus through the displacement block 16.

[0056] See the appendix Figure 11 , for the position adjustment position of the continuously connected steel plates 7 placed in the relatively upper stacked continuous combined connecting plates 4, first place the independent cushion blocks 5 correspondingly on the relatively lower continuous combined connecting plate 4 (positioned by means of the positions of the continuously connected steel plates 7 that have been pre-placed inside it), and then the continuously connected steel plates 7 in the relatively upper stacked continuous combined connecting plates 4 adjust the positions of the continuously connected steel plates 7 through the reverse positioning of the independent cushion blocks 5, so that the stacked independent cushion blocks 5 are always accurately positioned on the same straight line, and then disassemble and assemble. It should be noted that one magnet 8 needs to be installed at each of the upper and lower parts of the independent cushion block 5.

[0057] Considering that the independent pads 5 on the same continuous connecting steel plate 7 are located on the same straight line, but there are deviations in the positions of the independent pads 5 on different continuous connecting steel plates 7. Therefore, as shown in the attached Figure 10 figure, grooves can be pre-opened on the continuous connecting steel plate 7 to divide the positions, so that when placing the independent pads 5 at the groove positions, a difference in the attraction of the magnets 8 is formed (the attraction between the continuous connecting steel plate 7 at the notch and the magnet 8 is small), and it is easier to place the independent pads 5 on different continuous connecting steel plates 7 in the same straight line.

[0058] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
