Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering, in particular to an installation device that can be used for pre-embedded anchor pieces of double T-plates. Background Art
[0002] The predominant prestressed double-T slab currently on the market is widely used in floors and roofs of various types of buildings. A double-T slab is a precast reinforced concrete load-bearing structure combining a plate and beam, consisting of a wide faceplate and two narrow, high ribs. The faceplate serves as both a transverse load-bearing structure and a compression zone for the bending longitudinal ribs. Due to the large cross-section of the compression zone, the neutral axis approaches or enters the faceplate, resulting in a large moment arm for the tensile reinforcement, resulting in excellent structural mechanical properties.
[0003] In modern building design, electromechanical (EM) piping is increasingly integrated with the main structure, often requiring these complex piping systems to be secured to double-T panels using a bracket system. Traditionally, post-anchoring is often employed, with supports and hangers drilled directly into the ribs and underside of the double-T panels. This approach can have unforeseen effects on the prestressed tendons, potentially compromising the overall structural integrity of the double-T panels. Therefore, when considering how to safely and efficiently install EEM piping, particular attention must be paid to avoiding adverse effects on prestressed components. To this end, we propose an installation device for pre-embedded anchors in double-T panels. Utility Model Content

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0016] See also Figure 1-3 The utility model provides a technical solution: an installation device that can be used for embedded anchors of double T-plates, comprising a steel formwork 11 and an embedded part 2 arranged in the steel formwork 11. The cross-sectional shape of the embedded part 2 is T-shaped, and screw holes are opened on the lower surface of the embedded part 2. Bolts, screws, adapters, etc. can be installed through the screw holes on the lower surface of the embedded part 2 for rooting, avoiding the impact on the prestressed tendons during post-anchoring, maintaining the overall structural integrity of the double T-plate, and ensuring the overall safety of the building quality.
[0017] An interference fit hole 3 is provided on the upper surface of the embedded part 2, and an L-shaped connecting piece 5 is installed in the interference fit hole 3. The connecting piece 5 includes two connecting rods connected to each other by a connecting tee 9, one of the connecting rods is horizontal and the other connecting rod is vertical. The bottom end of the vertical connecting rod is interference fit in the interference fit hole 3 and is detachably connected to the embedded part 2. An adjusting sleeve 6 is provided between the connecting pieces 5 on the two adjacent embedded parts 2. The horizontal connecting rods on the two connecting pieces 5 are slidably set in the adjusting sleeve 6, and a number of positioning holes 7 are evenly provided on the side surface of the adjusting sleeve 6. Positioning pins or positioning screws are provided in the positioning holes 7. When the positioning pins are set, corresponding positioning holes 7 are also evenly provided on the horizontal connecting rod; when the positioning screws are set, the positioning holes 7 are screw holes that match them. The distance between the two embedded parts 2 is adjusted by moving the two connecting pieces 5 to adapt to different embedded anchor requirements, which greatly improves universality.
[0018] The preferred technical solution is that a level bead 8 is installed on the adjusting sleeve 6. By observing the level bead 8, the horizontality of the horizontal rod of the connecting member 5 can be adjusted, thereby ensuring the verticality of its vertical connecting rod and embedded part 2, and ensuring that the hole is vertical.
[0019] The preferred technical solution is that the screw hole of the embedded part 2 is threadedly connected with a reserved screw 1, and the lower surface of the steel formwork 11 is provided with a through hole corresponding to the reserved screw 1. After the embedded part 2 is fixed by the connecting part 5 and the position and verticality are adjusted, the reserved screw 1 can be tightened to form a through-fixing with the steel formwork 11, thereby avoiding the impact on the embedded part 2 during the later pouring of concrete and causing position displacement.
[0020] Optionally, the through holes on the steel template 11 can be strip holes, the width of which is slightly larger than the diameter of the reserved screw 1, so that the position of the embedded part 2 can be flexibly adjusted and fixed according to actual engineering needs; after the concrete is formed, the reserved screw 1 needs to be removed.
[0021] An optional technical solution is that the connecting piece 5 is connected to the extension rod 10 through the connecting tee 9, and the two extension rods 10 on both sides of the steel formwork 11 are connected by the adjusting sleeve 6, that is, a total of four groups of embedded parts 2 are provided at both ends of the entire double T-plate, and two groups are provided on both sides of the two ribs. All the connecting pieces 5 are connected by the extension rod 10, which further ensures the firm fixation and verticality of the embedded parts 2.
[0022] Optionally, a spring 4 is provided between the connector 5 and the embedded part 2 to act as a buffer when installing the connector 5 and the embedded part 2 and to provide a certain elastic force when disassembling the connector 5, making disassembly more convenient.
[0023] Further optionally, a protective sleeve is sleeved on the outside of the vertical connecting rod of the connecting piece 5, and the protective sleeve is sleeved on the outside of the spring 4 to prevent concrete from entering the spring and the connecting piece 5 from solidifying with the concrete when pouring concrete, so as to facilitate the removal of the connecting piece 5 after the embedded part 2 is fixed.
[0024] First, adjust the position of the connector 5 and the adjusting sleeve 6 according to the required hole position of the double T-plate, and fix the connector 5, the adjusting sleeve 6 and the extension rod 10 through positioning pins or positioning screws, and then form an interference fit between the bottom end of the vertical connecting rod of the connector 5 and the embedded part 2. After the adjustment is completed, place it on the inner membrane of the double T-plate prefabricated formwork steel formwork 11.
[0025] Then adjust the horizontal and vertical degrees of the embedded parts 2 on both sides by adjusting the horizontal beads on the sleeve 6. After adjusting until the hole section is vertical, tighten the reserved screw 1 and the nut at its bottom to form a fixed system between the embedded parts 2 and the steel template 11.
[0026] After the embedded parts 2 are fixed, the connector 5 is taken out by a puller or a press, and then C50 concrete can be poured into the steel formwork 11 .
[0027] After the concrete hardens, the reserved screw 1 is removed, and a fixing system is formed between the embedded part 2 and the concrete 12. Later, the embedded device can be directly screwed into it through an adapter, bolt, screw, etc. for rooting, which is convenient and quick.
[0028] When the protective sleeve and the spring 4 are provided on the connecting member 5, the concrete can be poured first, and then the connecting member 5 and the spring 4 are removed, and then the protective sleeve is repaired by filling with fine stone concrete.
