Description

Technical Field

[0001] The utility model relates to a prestressed solid square pile mould, belonging to the technical field of prefabricated production tools. Background Art

[0002] At present, the traditional molds of prestressed solid square piles are usually fixed with side molds on both sides. The traditional mold opening method requires a crane to lift the formed concrete piles out of the mold, which leads to the following problems in the traditional mold opening method: the prestressed solid square pile mold is usually about 15 meters long, and the large number of connecting bolts for fixing the side molds leads to slow and inefficient disassembly of the side molds, wasting a lot of manpower; the fixed side molds lead to a relatively small operating space during the production stage, and workers can only adjust the steel cage and arrange the hanging points from directly above the mold, which is inconvenient to operate and has low worker production efficiency; in addition, the fixed side molds lead to greater friction between the concrete and the mold after hardening, which increases the demoulding adsorption force. The solid square piles need to be forcibly removed from the mold, which has low demoulding efficiency and is easy to bump and damage the solid square piles. Utility Model Content

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0024] In order to further understand the content of the utility model, this technical solution is further explained below in conjunction with specific implementation methods.

[0025] Example 1: Figures 1 to 5As shown, this embodiment provides a prestressed solid square pile mold, including a first side mold 1, a second side mold 2, a bottom mold 3, and a side mold 4. The first side mold 1, the second side mold 2, and the side mold 4 are located above the bottom mold 3. The first side mold 1 and the second side mold 2 are arranged relatively parallel, and the side mold 4 is located on both sides of the first side mold 1 and the second side mold 2. The first side mold 1, the second side mold 2, the bottom mold 3, and the side mold 4 together form a U-shaped groove. The bottom end of the second side mold 2 is detachably connected to the bottom mold 3. Specifically, the second side mold 2 and the bottom mold 3 are both provided with a fixing plate for the tension bolts 6 to pass through. The bottom end of the second side mold 2 is connected to the bottom mold 3 by the tension bolts 6. A slide 10 is provided on the outside of the bottom mold 3 near the direction of the second side mold 2 and perpendicular to the bottom mold 3. In this embodiment, the slide 10 is made of I-beam or channel steel. The outer wall of the second side mold 2 is also provided with a pulley assembly 5, which can move along the slide 10. Specifically, the pulley assembly 5 includes a connecting plate 51, a connecting rod 52, and a running wheel 53. The connecting rod 52 is connected to the connecting plate 51 at both ends, and the running wheel 53 rolls around the connecting rod 52. The connecting plate 51 is connected to the side wall of the second side mold 2. The number of pulley assemblies 5 is not limited, as long as the overall stability of the mold is guaranteed.

[0026] The bottom end of the first side form 1 has a row of connection holes 7, and the top surface of the bottom form 3 has multiple rows of screw holes 8. In this embodiment, the spacing between adjacent rows of screw holes 8 is 50 mm, and the spacing between the same row of screw holes 8 is 300 mm. The rows of screw holes 8 are parallel to the first side form 1, that is, the rows of connection holes 7 correspond one-to-one with the rows of screw holes 8. The bottom end of the first side form 1 can be selectively aligned above any row of screw holes 8 on the bottom form 3 and secured with bolts. By adjusting the first side form 1 to different positions on the bottom form 3, different prestressed pile diameters can be accommodated. Similarly, the second side form 2 and the bottom form 3 can be secured together using bolts and nuts.

[0027] In order to ensure the verticality and spacing between the first side mold 1 and the second side mold 2, the mold is also provided with a fixing assembly 9. In this embodiment, the fixing assembly 9 includes a strut 91, a first support 92, a second support 93, and a fastening nut 94. The first support 92 is fixed to the top of the first side mold 1, and the second support 93 is fixed to the top of the second side mold 2. The strut 91 has external threads all around, and one end of the strut 91 is hinged to the second support 93. Specifically, the first support 92 includes a baffle 97 and a side plate 98. The side plate 98 and the baffle 97 form a U-shape. The baffle 97 is provided with a through hole for the strut 91 to pass through. After the other end of the strut 91 passes through the baffle 97, it is tightened and fixed by the fastening nut 94, and the fastening nut 94 is stuck on the baffle 97.

[0028] The first side mold 1, second side mold 2, and bottom mold 3 are all composed of steel tubes 11 and parallel steel plates 12. The steel tubes 11 are positioned between the steel plates 12 and secured by welding, with screw holes 8 located on the steel tubes 11. When the molds need to be closed, the support rods 91 pass through the baffles 97, and the tightening nuts 94 are then rotated to secure the support rods 91. This controls the upper spacing and verticality of the first and second side molds 1 and 2. The lower spacing and verticality of the first and second side molds 1 and 2 are controlled by the combination of bolts, tightening nuts 94, and tension bolts 6. When the molds need to be opened, the support rods 91 are separated from the first support 92 by removing the tightening nuts 94 and tension bolts 6, and then pushing the second side mold 2 to remove the support rods 91 from the first support 92.

[0029] Example 2: Different from Example 1, Figures 1 to 4 and Figure 6 As shown, this embodiment has made a new design for the fixing component 9, specifically, the fixing component 9 includes a support rod 91, a first support 92 and a second support 93, the first support 92 and the second support 93 are respectively fixed to the top of the first side mold 1 and the second side mold 2, one end of the support rod 91 is hinged to the second support 93, and a plurality of grooves 95 are arranged at intervals on the other end of the support rod 91, and the grooves 95 extend from one side of the support rod 91 to the other side of the support rod 91, and the top of the first support 92 is provided with a fixing pin 96, which can be stuck in any groove 95, so that the support rod 91 cannot move.

[0030] When the mold needs to be closed, the support rod 91 is lowered so that the fixing pin 96 is stuck in the groove 95 to control the upper spacing and verticality of the first side mold 1 and the second side mold 2. The bolt and the fastening nut 94 cooperate and pull the bolt 6 to control the lower spacing and verticality of the first side mold 1 and the second side mold 2. When the mold needs to be opened, the support rod 91 is pushed away from the opening of the groove 95, that is, the fixing pin 96 is separated from the groove 95, and the second side mold 2 is pushed to separate the support rod 91 from the first support 92.

[0031] Example 3: Different from Example 1 and Example 2, Figure 7 As shown, this embodiment uses both the fixing components in Example 1 and Example 2. In this embodiment, the fixing component 9 of Example 1 and the fixing component 9 of Example 2 are spaced apart. As long as the support rod 91 can ensure the verticality of the first side mold 1 and the second side mold 2 and the spacing between the first side mold 1 and the second side mold 2, it will be sufficient.

[0032] After the mould is put into the place where the concrete is to be poured, the second mould 2 is put into the place where the concrete is to be poured, and the mould is put into the place of the second mould 2. When the mould is put into the place where the concrete is to be poured, the mould is put into the place of the second mould 2. When the mould is put into the place where the concrete is to be poured, the mould is put into the place where the concrete is to be poured, and the mould is put into the place where the concrete is to be poured, the mould is put into the place where the concrete is to be poured, and the mould is put into the place where the concrete is to be poured. The present invention solves many problems such as the difficulty in laying the prestressed pile reinforcement cage 14, the low demoulding efficiency, and the easy damage of components.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
