DETAILED DESCRIPTION

[0029] In order to make the purpose, characteristics and advantages of the patent more obvious and easy to understand, the technical solutions in the above embodiments of the patent are described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the patent, not all. Based on the embodiments in the patent, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the patent. EMBODIMENT

[0030] Figure 2 A schematic view of a lead screw vertical rod supporting device of the utility model, Figure 10 A schematic view of a lead screw vertical rod supporting device of the utility model in use. Referring to Figure 2 , Figure 10 A lead screw vertical rod supporting device suitable for a socket type disc buckle type mold frame, comprising: a lead screw vertical rod 1, a sleeve with an inner buckle 2, a disc inner thread sleeve 3, a portable joist 4, and an adjustable U bracket 6. Among them:

[0031] The lead screw vertical rod 1 is the main force component, which is subjected to the vertical downward force of the adjustable U bracket 6 at the top and the vertical downward force transmitted by the disc inner thread sleeve 3 through the friction of the threads of the portable joist 4. Finally, it is transmitted to the socket type disc buckle type mold frame at the bottom of the lead screw vertical rod 1. In this embodiment, the lead screw vertical rod adopts a steel pipe with an outer diameter of 48.3 mm, a wall thickness of 3.2 mm, and a length of 1000 mm, and the material is Q355.

[0032] After designing the socket type disc buckle type mold frame according to the distribution of the beam, the height of the vertical rod 8 and the specification of the portable joist 4 are determined. The bottom end of the lead screw vertical rod 1 is connected to the vertical rod 8 through the sleeve with an inner buckle 2 to form a whole.

[0033] The lead screw vertical rod 1 is screwed with the disc inner thread sleeve 3, and the length is adjusted by screwing in or out, so as to adapt to the size requirements of the beam under support in different working conditions, and rely on the friction force between the threads to increase the fastening degree of the connection. The lead screw vertical rod 1 is sleeved with two sets of disc inner thread sleeves 3 on both sides of the beam, the first set of disc inner thread sleeves 3a is the support of the portable joist, and the disc inner thread sleeve II 3b is the connection point of the top cross bar 5. The portable joist 4 is the main force component of the beam under support. The size of the joist 4 is the same as that of the cross bar 5, which is a standard part, and the size includes: 600 mm, 900 mm, 1200 mm.

[0034] The load of the disc shear bearing beam in the disc inner wire sleeve 3 is 21kN according to the requirement of the specification JG / T503-2016, and the disc shear can be 40kN according to the specification JGJ300-2013; the specification JGJ / T231-2021 also clearly indicates that the disc shear can be 40kN; according to the requirement of the disc shear in the above-mentioned specifications, the beam section range that can be constructed by the utility model is larger, and the section below 0.7m2 can be used according to the calculation of the longitudinal distance of 1.5m.

[0035] The top end of the screw rod vertical rod 1 is connected with the adjustable U support 6 through the nut 7, the disc inner wire sleeve 3 is sleeved on the screw rod vertical rod 1, the portable support beam 4 is inserted into the disc inner wire sleeve 4 by sleeving two disc inner wire sleeves 3 on two screw rod vertical rods 1 at a certain distance on the same horizontal plane, and a whole is formed, so that the beam support effect is realized.

[0036] During construction, the layout of the disc buckle type formwork is determined according to the design drawing, the bottom socket type disc buckle vertical rod 8 is first erected at a specified interval and connected into a preliminary frame structure through the cross rod 5. At the position where the screw rod vertical rod support device is needed to be used, the inner sleeve sleeve 2 at the bottom end of the screw rod vertical rod 1 is inserted and connected to the top end of the bottom socket type disc buckle vertical rod 8 in a targeted manner, so as to ensure that the inner sleeve sleeve 2 is completely sleeved and tightly matched, the insertion depth is not less than half of the length of the inner sleeve sleeve 2 (in this embodiment, not less than 100mm), and then appropriate tools (such as a hammer) are used to gently knock the inner sleeve sleeve 2, so that the connection between the inner sleeve sleeve 2 and the bottom socket type disc buckle vertical rod 8 is more firm, and loosening or displacement in the subsequent construction process is prevented.

[0037] According to the design requirement of the floor height, the extension length of the adjustable U support 6 is adjusted by rotating the nut 7 at the top end of the screw rod vertical rod 1, and the overall height of the screw rod vertical rod 1 is preliminarily determined. At the position where the portable support beam 4 is needed to be placed, two disc inner wire sleeves 3 are first rotated into the same horizontal plane of the screw rod vertical rod 1 at a certain distance (determined according to the beam width and design requirement) on both sides of the beam, and the rotation depth needs to ensure that the disc inner wire sleeve 3 can be stably fixed on the screw rod vertical rod 1 and the threaded connection is tight, and will not loosen due to subsequent construction vibration and other factors. Then the portable support beam 4 with appropriate size (for example, 900mm) is stably inserted into the disc inner wire sleeve 3, so as to ensure that the both ends of the portable support beam 4 are completely inserted and tightly matched with the disc inner wire sleeve (3) without shaking or excessive gap.

[0038] After the installation of part of the screw rod vertical rod support device is completed, the overall inspection and adjustment of the socket type disc buckle formwork are carried out. The verticality of each screw rod vertical rod 1 is checked, the height of the adjustable U support 6 at the top end of each screw rod vertical rod 1 is measured by using a level meter and other measuring tools, and it is ensured that all the screw rod vertical rods 1 are on the same horizontal plane, and the allowable error is controlled within ±5mm.

[0039] During the whole process of concrete floor pouring construction, the screw rod vertical pole support device bears the weight of the formwork, steel bars and concrete, etc. Through the synergistic effect of various components, the load is effectively transmitted to the foundation ground, ensuring the safety and smooth progress of the construction process. After the construction is completed, the screw rod vertical pole support device is disassembled in the reverse order, the components are cleaned and properly stored, so as to be reused in subsequent projects.
