DETAILED DESCRIPTION

[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] Please also read Figure 1, the position adjustment device for the wedge block at the bottom of the prefabricated beam provided by the present invention is now described. The position adjustment device for the wedge block at the bottom of the prefabricated beam comprises a fixing member 1, a sliding member 2 and a fixing plate 3. The fixing member 1 is used to be arranged on one side of the length direction of the prefabricated pedestal and is fixedly connected to the prefabricated pedestal. The fixing member 1 has a first protruding portion 11 protruding upward, and the first protruding portion 11 fits with the prefabricated pedestal. The sliding member 2 is located on the side of the fixing member 1 away from the prefabricated pedestal. The sliding member 2 is slidably connected to the fixing member 1 and the sliding direction is set along the length direction of the prefabricated pedestal. A reserved groove 21 is provided on the sliding member 2. The fixing plate 3 is horizontally arranged and located between the sliding member 2 and the first protruding portion 11. One end of the fixing plate 3 is fixedly connected to the sliding member 2. The sliding of the sliding member 2 can make the fixing plate 3 fit with the first protruding portion 11. Among them, the upper surfaces of the first protruding portion 11, the sliding member 2 and the fixing plate 3 are all flush with the upper surface of the prefabricated pedestal.

[0026] Compared with the prior art, the device for adjusting the position of the wedge block at the bottom of the precast beam provided by the present invention can be used for the construction of a precast beam of a certain length when the fixing plate 3 is fitted with the first protrusion 11. When the length of the precast beam changes, the sliding member 2 is driven to slide to a suitable position. At this time, the position of the reserved groove 21 changes, so that the length of the precast beam and the position of the wedge block on the precast beam also change accordingly, so that the position of the wedge block is adapted to the length of the precast beam. After filling the gap between the fixing plate 3 and the first protrusion 11, it can be used for the construction of the precast beam. In this way, the problem that the current precast beam prefabrication pedestal cannot be applied to the construction of precast beams of different lengths can be avoided.

[0027] In this way, it is equivalent to setting the reserved groove 21 on the original prefabricated base on the sliding member 2.

[0028] In some embodiments, see Figure 1 The fixing member 1 also has a second protrusion 12 protruding upward, the second protrusion 12 is located on the side of the first protrusion 11 away from the prefabricated pedestal, and the second protrusion 12 is slidably fitted with the bottom surface of the fixing plate 3. The support of the fixing plate 3 by the second protrusion 12 can prevent the fixing plate 3 from deforming.

[0029] In some embodiments, see Figure 1 and Figure 3, a placement groove 13 is formed between the second protrusion 12 and the first protrusion 11, and the position adjustment device of the wedge block at the bottom of the precast beam also includes a plurality of limit assemblies. The plurality of limit assemblies are located between the second protrusion 12 and the first protrusion 11, and the limit assemblies include a limit plate 41, and the plurality of limit plates 41 are sequentially arranged in affixed with each other along the sliding direction of the sliding member 2, one of the limit plates 41 is in affixed with the first protrusion 11, and the limit plate 41 is arranged horizontally, and the limit plate 41 is slidably connected with the fixing member 1 along the vertical direction, so that the limit plate 41 has a first position located in the placement groove 13 and a second position located outside the placement groove 13, and when the limit plate 41 is in the second position, the upper surface of the limit plate 41 is flush with the upper surface of the first protrusion 11. Since the second protrusion 12 is lower than the second protrusion 12, the limit plate 41 is located outside the placement groove 13, that is, above the second protrusion 12. When the sliding of the sliding member 2 causes a gap between the fixed plate 3 and the first protruding portion 11, the limiting plate 41 can slide upward to the second position, thereby filling the gap between the fixed plate 3 and the first protruding portion 11. In this embodiment, when the gap between the fixed plate 3 and the first protruding portion 11 can accommodate one limiting plate 41, the limiting plate 41 near the first protruding portion 11 slides to the second position; when the gap between the fixed plate 3 and the first protruding portion 11 can accommodate two limiting plates 41, the limiting plate 41 near the first protruding portion 11 and the limiting plate 41 adjacent to the limiting plate 41 both slide to the second position, and so on.

[0030] In some embodiments, see Figure 5 The fixing member 1 has an installation cavity 14 located below the placement groove 13, and the installation cavity 14 passes through both ends of the fixing member 1 along the width direction of the prefabricated pedestal. The limiting assembly also includes a limiting tube 42 and at least two sliding shafts 43. The limiting tube 42 is located in the installation cavity 14 and is arranged along the width direction of the prefabricated pedestal. At least two sliding shafts 43 are arranged in sequence along the length direction of the limiting tube 42, and the sliding shaft 43 is vertically arranged and slidably penetrated in the fixing member 1, and the upper and lower ends of the sliding shaft 43 are fixedly connected to the limiting plate 41 and the limiting tube 42 respectively. The limiting plate 41 is slidably connected to the fixing member 1 through the sliding shaft 43. The limiting tube 42 can prevent the sliding shaft 43 from sliding upward and disengaging from the fixing member 1.

[0031] In some embodiments, see Figure 3, the limiting assembly close to the first protruding portion 11 is the first limiting assembly, and the remaining limiting assemblies are all second limiting assemblies. Each second limiting assembly is provided with a supporting assembly located in the mounting cavity 14. The supporting assembly is located on the side of the limiting tube 42 in the second limiting assembly facing the first protruding portion 11. The supporting assembly includes a transfer member 51 and a plurality of supporting shafts 52. The transfer member 51 is fixedly connected to the limiting tube 42 in the second limiting assembly. The plurality of supporting shafts 52 are sequentially arranged at intervals along the length direction of the limiting tube 42. The supporting shaft 52 is arranged along the sliding direction of the sliding member 2 and one end is fixedly connected to the transfer member 51. When the supporting shaft 52 moves upward, the supporting shaft 52 can support the connected limiting tube 42 upward to move the limiting tube 42 on the side of the first protruding portion 11 upward, so that the limiting plates 41 corresponding to the two limiting tubes 42 can reach the second station synchronously. The limiting tube 42 connected to the supporting shaft 52 refers to the limiting tube 42 fixedly connected to the supporting shaft 52 through the transfer member 51. The limiting plate 41 corresponding to the limiting tube 42 refers to the limiting tube 42 in the limiting assembly where the limiting tube 42 is located. Since the supporting shaft 52 can support the limiting tube 42 connected to the limiting tube 42 facing the side of the first protrusion 11, when the limiting plate 41 in one of the second limiting assemblies is in the second position, all the limiting plates 41 of the second limiting assembly facing the side of the first protrusion 11 are in the second position.

[0032] In some embodiments, see Figure 3 The bottom surface of the installation cavity 14 is provided with a sliding groove 15, the length direction of the sliding groove 15 is arranged along the sliding direction of the sliding member 2 and penetrates the fixing member 1 in the direction of the sliding member 2, and the precast beam bottom wedge block position adjustment device also includes a sliding rod 6. The sliding rod 6 is slidably arranged in the sliding groove 15 and is fixedly connected to the sliding member 2. The sliding member 2 is slidably connected to the fixing member 1 through the sliding cooperation between the sliding rod 6 and the sliding groove 15.

[0033] In some embodiments, see Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6The position adjustment device of the wedge block at the bottom of the precast beam also includes a follower 7 and a locking assembly located in the installation cavity 14. The follower 7 is fixed on the sliding rod 6. The locking assembly includes a docking member 81, a connecting shaft 82, two compression springs 83, a support member 84 and a limiting shaft 85. The docking member 81 is fixed on the follower 7. The docking member 81 is located on one side of the sliding rod 6 along the length direction of the limiting tube 42. There are two connecting shafts 82. The connecting shafts 82 are parallel to the limiting tube 42 and are slidably penetrated in the docking member 81. The side of the connecting shaft 82 has an abutment portion 821 protruding outward. The abutment portion 821 is located on the side of the docking member 81 facing the sliding rod 6. The two compression springs 83 are respectively sleeved on the two connecting shafts 82, and the two ends of the compression springs 83 are respectively abutted against the abutment portion 821 and the docking member 81. The support member 84 is located on the side of the connecting shaft 82 away from the sliding rod 6, and the support member 84 is fixedly connected to both connecting shafts 82. The limiting shaft 85 is parallel to the limiting tube 42, and the limiting shaft 85 is located on the side of the support member 84 facing the sliding rod 6 and is fixedly connected to the support member 84. When several limiting plates 41 are synchronously in the second position, the limiting shaft 85 can slide into the limiting tube 42 corresponding to the limiting plate 41 close to the sliding member 2. The locking assembly can slide with the sliding rod 6 through the follower 7. Before the sliding member 2 and the sliding rod 6 slide, the connecting shaft 82 is first slid, so that the support member 84 moves to a suitable position in the direction away from the docking member 81. When the sliding member 2 slides into place, it drives several limiting plates 41 to slide to the second position, thereby filling the gap between the fixed plate 3 and the first protrusion 11. Then, the limiting shaft 85 on the support member 84 is inserted into the limiting tube 42 corresponding to the limiting plate 41 near the sliding member 2 through the sliding of the connecting shaft 82. Since the supporting shaft 52 can support the limiting tube 42 connected to the limiting tube 42 toward the first protrusion 11 side, as long as the limiting shaft 85 is inserted into the limiting tube 42 corresponding to the limiting plate 41 near the sliding member 2, all the limiting plates 41 in the second position can be restricted from sliding downward. At the same time, the sliding member 2 can also be restricted from continuing to slide. The resilience of the compression spring 83 can increase the resistance of the limiting shaft 85 to sliding out of the limiting tube 42. In this embodiment, the limiting tube 42 corresponding to the limiting plate 41 refers to the limiting tube 42 in the limiting assembly where the limiting plate 41 is located.

[0034] Furthermore, two locking components may be provided on the follower 7 , and the two locking components are symmetrically arranged on both sides of the sliding rod 6 .

[0035] In some embodiments, see Figure 3 and Figure 4The position adjustment device for the wedge block at the bottom of the precast beam also includes a positioning member 10. The positioning member 10 is located on the side of the limiting tube 42 in the first limiting assembly facing the first protruding portion 11, and the positioning member 10 is fixedly connected to the limiting tube 42. When the fixing plate 3 is in contact with the first protruding portion 11 and the supporting member 84 is in contact with the docking member 81, the supporting member 84 abuts against the end of the positioning member 10 away from the connected limiting tube 42. In this way, the sliding member 2 can be restricted from sliding further, so that the fixing plate 3 and the first protruding portion 11 remain in contact.

[0036] In some embodiments, see Figure 1 and Figure 5 The fixing member 1 has two notches 16 corresponding to each limiting plate 41. The two notches 16 are symmetrically arranged at both ends of the fixing member 1 along the length direction of the limiting tube 42. The notches 16 are connected to the placement groove 13 and the installation cavity 14. The two symmetrically arranged notches 16 facilitate driving the limiting plate 41 at the location to slide upward.

[0037] In some embodiments, see Figure 1 , Figure 2 , Figure 5 and Figure 7The position adjustment device of the wedge block at the bottom of the precast beam also includes a push-out assembly, which includes a bracket 91, a connecting member 92, a supporting rod 93, a power shaft 94, a driving shaft 95, a guide shaft 96, two lifting members 97 and two insertion members 98. The bracket 91 is used to be arranged on the first protruding portion 11 and the fixed plate 3. The bracket 91 has two fixed shafts 911 arranged in parallel, and the fixed shafts 911 are parallel to the sliding rod 6. The connecting member 92 is slidably sleeved on the two fixed shafts 911, and the connecting member 92 is provided with a threaded hole with the axis vertically arranged. The supporting rod 93 is parallel to the limiting tube 42 and is located below the connecting member 92. The power shaft 94 is inserted into the threaded hole and is provided with an external thread threadedly connected to the threaded hole. The power shaft 94 can rotate to penetrate the supporting rod 93. The side wall of the power shaft 94 has a supporting portion 941 protruding outward, and the supporting portion 941 is in contact with the lower surface of the supporting rod 93. The driving shaft 95 is perpendicular to the power shaft 94 and fixedly connected to the upper end of the power shaft 94. There are two guide shafts 96, which are vertically arranged. The guide shafts 96 are fixedly connected to the connecting member 92 and slidably penetrated in the supporting rod 93. Two lifting members 97 are respectively located on both sides of the limiting plate 41 along the length direction of the limiting tube 42, and the lifting members 97 are slidably sleeved on the supporting rod 93. Two insertion members 98 are located between the two lifting members 97 and are respectively fixedly connected to the two lifting members 97. The sliding of the two lifting members 97 can make the two insertion members 98 penetrate into the two symmetrically arranged notches 16 respectively. The supporting rod 93 is slidably connected to the connecting member 92 in the vertical direction through the guiding shaft 96. It is more convenient to drive the power shaft 94 to rotate through the driving shaft 95. When the driving shaft 95 rotates, the power shaft 94 threadedly connected to the connecting member 92 can move in the vertical direction. When the power shaft 94 moves upward, the supporting portion 941 can support the supporting rod 93 to move upward, and when the power shaft 94 moves downward, the supporting rod 93 can move downward under the action of gravity. When one of the limit plates 41 needs to slide upward to the second station, the driving connecting member 92 slides, so that the two insertion members 98 are aligned with the two notches 16 at the limit plate 41, and then the two insertion members 98 are respectively inserted into the two notches 16 by sliding the two lifting members 97, and then the power shaft 94 is driven to move upward. The supporting rod 93 will drive the two insertion members 98 to move upward through the two lifting members 97, so that the two insertion members 98 push the limit plate 41 upward to the second station. After the use of the push-up assembly is completed, the push-up assembly is removed.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
