Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a one-time pre-buried fine installation positioning device using a floor slab sleeve. Background Art

[0002] In the current traditional construction process of pre-buried multi-story buildings, foam boards, plastic boxes or nailed wooden boxes are mainly buried at the vertical pipe position before concrete pouring, and the pre-buried foam boards, plastic boxes or wooden boxes are removed before the pipeline is installed later to facilitate the installation of casing hanging formwork. This process is very costly: prefabrication of foam boards or wooden boxes of appropriate sizes in advance, as well as later removal, roughening of holes, and casing hanging formwork all require increased labor costs; the secondary utilization rate of foam boards and wooden boxes is almost zero, and the process material flooding cost is close to 100%; the secondary hanging formwork of the floor increases the risk of leakage and the cost of handling leakage; ④ The pipeline installation cycle is greatly increased, which indirectly causes an increase in labor costs.

[0013] The technical solution of the utility model is described in detail below with reference to the accompanying drawings, but the protection scope of the utility model is not limited to the embodiments.

[0014] Reference Figure 1 and Figure 2 The utility model discloses a one-time pre-embedded fine-fitting positioning device for penetrating floor slab casing, comprising a steel plate outer frame 1, on which two level bubbles 2 are fixedly arranged, two calibration rulers 7 are arranged on the midpoint connection line of the inner opposite sides of the steel plate outer frame 1, the calibration ruler 7 is provided with scales, an infrared calibration device 6 is arranged on the coincidence point of the two calibration rulers 7, and fixing clamps 3 are installed on the four directions of the coincidence point of the two calibration rulers 7, the fixing clamps 3 are bent into an arc shape on the side close to the infrared calibration device 6, and are made of 2mm thick galvanized steel plate, and the four fixing clamps 3 are installed with clamp fixing bolts 4 located on the calibration ruler 7 on the side away from the infrared calibration device 6, and the four fixing clamps 3 are connected with 5mm thick galvanized steel plates 8 in the vertical direction, and the 5mm thick galvanized steel plates 8 are close to the outer wall of the pre-embedded casing 9 of the next floor.

[0015] In the utility model, the fixing fixture 3 on the four calibration scales 7 is slid to make the 5mm thick galvanized steel plate 8 connected to the fixture close to the outer wall of the casing, and the readings of the corresponding positions of the fixtures on the four scales are fine-tuned to be the same; secondly, the two level bubbles 2 of the level ruler are observed and fine-tuned until the two bubbles are both centered, indicating that the entire positioning and calibration device is in a horizontal state; tighten the fixture fixing bolts 4 to make the 5mm thick galvanized steel plate 8 reliably fixed on the pre-buried casing 9 of the next floor to be positioned and measured; open the infrared calibration device 6 in the center of the calibration scale 7, find the infrared light spot on the template 11 of the previous floor, and drill a hole at the light spot to locate the center of the pre-buried casing 10 of the previous floor; weld two short angle steels with eyes on the side of the casing in advance, locate the casing according to the drilling position of the template, and fix the short angle steel on the casing to the template with screws to prevent the casing from shifting. At this point, the method for one-time pre-embedded positioning of pre-embedded casing through the floor slab has completed the construction of a complete set of process flows.

[0016] The utility model first fixes itself on the embedded sleeve 9 extending out of the concrete floor slab 13 of the next floor, and the light beam 12 emitted by the infrared calibration device 6 hits the template of the previous floor. The hole drilled at the light spot is the center of the embedded sleeve 10 to be positioned on the previous floor. The sleeve penetrating the floor slab is installed in place at one time before pouring, and there is no need for prefabrication and embedding, removal of foam or wooden boxes, and no need to roughen the hole or hang the mold, which greatly improves the construction efficiency and greatly reduces the construction cost. It ensures that the accuracy of the embedded sleeve meets the pipeline installation, and can be flexibly applied to the embedded sleeves of various specifications and different positions for repeated use.
