Abstract
Description
Technical Field
[0001] This utility model relates to the field of slipform construction technology, and in particular to a fixing device for hydraulic lifting support rods in slipform construction. Background Technology
[0002] Many buildings now use slipform construction technology, which can improve construction efficiency. Slipform construction uses a hydraulic lifting device in conjunction with supporting rods to lift the slipform frame as a whole, thus eliminating the need to repeatedly build construction scaffolds and improving construction efficiency. It is mainly used for building construction with the same cross-sectional shape, such as the construction of large cylindrical grain silos.
[0003] During slipform construction, the formwork is supported by a large number of support rods. As the concrete is poured, the support rods are embedded in the concrete. However, in the early stages of construction, the lower end of each support rod needs to be fixed to the base plate using a fixing device and kept perpendicular to the horizontal plane. This reduces resistance during the lifting process. Currently, the fixing device uses bolts and shims to adjust the verticality, which is inconvenient to install and adjust. Utility Model Content
[0004] In order to solve the above-mentioned problems in the prior art, this utility model provides a fixing device for hydraulic lifting support rods of sliding mold that is stable to install and easy to adjust.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A fixing device for a hydraulic lifting support rod in a sliding mold includes a base and an adjusting assembly. The base has several connecting holes along its edge, and a positioning tube perpendicular to the base is located at the center of the base. The positioning tube has a positioning hole at its center, which is a tapered hole with a larger upper end and a smaller lower end. The lower end of the positioning hole is clearance-fitted with the support rod. The adjusting assembly is located at the upper end of the positioning tube and includes a limiting sleeve that is clearance-fitted with the outer wall of the support rod, and three sets of connecting arms horizontally fixed to the outer periphery of the limiting sleeve. The outer end of each connecting arm has a downwardly protruding connecting block. The connecting block has horizontally distributed first threaded holes, and a first bolt is installed in each of the first threaded holes. The inner end of the first bolt abuts against the outside of the positioning tube.
[0007] By adopting the above technical solution: the base and the embedded parts on the base plate are fastened together by bolts or screws and nuts. Then, the lower end of the support rod is inserted into the positioning hole after passing through the limiting sleeve. Since the positioning hole is a conical hole, the support rod is not completely positioned at this time. Then, the three first bolts are tightened. The inner end of the first bolts abuts against the outside of the positioning tube. With the help of the verticality detector, the three first bolts are finely adjusted so that the support rod is kept perpendicular to the horizontal plane.
[0008] Preferably, a tapered protrusion, smaller at the top and larger at the bottom, is provided at the center of the lower end of the positioning hole, forming an annular groove between the tapered protrusion and the positioning hole. The support rod has a tubular structure, with its lower end locked in the annular groove, ensuring stable positioning of the lower end of the support rod.
[0009] Preferably, the outer wall of the positioning tube and the top surface of the base are supported by three sets of circumferentially evenly distributed ribs. The upper outer side of each rib has a vertical positioning surface. The connecting block is positioned outside the positioning surface and forms an adjustment gap with it. The inner end of the first bolt abuts against the positioning surface. The ribs increase the connection strength between the positioning tube and the base and also provide support for tightening the first bolt.
[0010] Preferably, the top surface of the rib is provided with a second threaded hole perpendicular to the base, and the connecting arm is provided with a waist-shaped hole corresponding to the second threaded hole. The waist-shaped hole and the second threaded hole are connected by a second bolt. After the support rod is adjusted to a vertical state by the first bolt, the connecting arm and the top surface of the rib are locked by the second bolt to further position the adjustment assembly.
[0011] Preferably, the upper end of the positioning tube is provided with a groove corresponding to the connecting arm, the width of the groove being greater than the width of the connecting arm, and the connecting arm is correspondingly inserted into the groove. An annular gap is formed between the outer periphery of the limiting sleeve and the upper inner wall of the positioning hole. The groove is used for positioning the connecting arm, preventing the adjusting assembly from rotating freely in the circumferential direction, and facilitating the tightening and adjustment of the first bolt.
[0012] Preferably, the base has three sets of connecting protrusions evenly distributed along its edge. These connecting protrusions are integrated with the base, with the bottom surface of each protrusion protruding beyond the bottom surface of the base, and the top surface of each protrusion protruding beyond the top surface of the base. The lower end of each protruding rib is integrated with the top surface of the connecting protrusion. Connecting holes are located on the connecting protrusions. The connecting protrusions increase the strength of the base and reduce the contact area between the bottom surface of the base and the base plate, preventing small particles or protrusions from affecting the installation of the base.
[0013] Preferably, the upper side of the positioning tube is provided with a pouring hole for injecting concrete into the positioning hole. After the supporting rod is adjusted to a vertical position, concrete is injected into the positioning tube through the pouring hole. After the concrete solidifies, it can better fix the supporting rod.
[0014] Therefore, this utility model has the advantages of stable installation and convenient adjustment. Attached Figure Description

The outer end of each connecting arm 21 has a downwardly protruding connecting block 22. The connecting block 22 has horizontally distributed first threaded holes 23, and a first bolt 24 is installed inside each first threaded hole 23. The inner end of the first bolt 24 abuts against the outside of the positioning tube 3. A tapered protrusion 31, smaller at the top and larger at the bottom, is located at the center of the lower end of the positioning hole 30, forming an annular groove 32 between the tapered protrusion and the positioning hole.
[0026] The outer wall of the positioning tube 3 and the top surface of the base 1 are supported by three sets of circumferentially evenly distributed ribs 33. The upper outer side of the ribs 33 is provided with a vertical positioning surface 330. The connecting block 22 is set on the outer side of the positioning surface 330 and forms an adjustment gap with the positioning surface 330. The inner end of the first bolt 24 abuts against the positioning surface 330. The top surface of the ribs 33 is provided with second threaded holes 331 distributed perpendicular to the base 1. The connecting arm 21 is provided with a waist-shaped hole 210 corresponding to the second threaded hole 331.
