Description

Technical Field

[0001] This utility model relates to a construction structure for floor settlement without opening holes, belonging to the field of building construction technology. Background Technology

[0002] In a building structure, the recessed area that sinks downward will occupy the space below, resulting in inconsistent heights of the support rods that support the bottom steel formwork of the floor slab.

[0003] The existing building structure support technology for recessed areas, as described in Chinese Patent Publication No. CN217811195U, uses multiple square timbers to support the bottom formwork, which further occupies the space for the recessed area to descend. Summary of the Invention

[0004] To solve the above-mentioned technical problems, this utility model provides a construction structure for opening holes at the floor settlement point.

[0005] This utility model is achieved through the following technical solution.

[0006] This utility model provides a construction structure for opening holes at floor settlement points, comprising: A prefabricated groove bottom body with positioning steel plates embedded at both ends; The positioning steel plates at both ends of the precast groove bottom are fixed in accordance with the bottom steel mold and the inner steel mold.

[0007] The precast groove bottom with positioning steel plate has L-shaped cast-in-place bodies at both ends, and the vertical section of the cast-in-place body and the precast groove bottom form a floor settlement groove.

[0008] The precast groove bottom is pre-embedded with connecting ribs that extend into the cast-in-place body, and the precast groove bottom and the cast-in-place body are connected by the connecting ribs.

[0009] The inner steel molds are supported from the inside by telescopic rods.

[0010] The bottom of the horizontal section of the bottom steel formwork has a support rod for support; the top of the inner steel formwork is fixedly connected to a reinforcing rod, the bottom surfaces of both ends of the reinforcing rod can contact the cast-in-place body, and the two ends of the reinforcing rod are fixedly connected to the horizontal section of the bottom steel formwork by through bolt assemblies.

[0011] An opening sleeve is pre-embedded in the cast-in-place body corresponding to the through bolt assembly, and the opening sleeve forms an opening for the bolt body of the through bolt assembly to pass through.

[0012] The beneficial effects of this utility model are as follows: the vertical section of the cast-in-place body is poured through the casting space formed by the inner steel mold, the vertical section of the bottom steel mold, and the precast groove bottom body. The top of the precast groove bottom body is connected and limited to the vertical section of the bottom steel mold through the positioning steel plate. The top of the precast groove bottom body is connected and limited to the horizontal section of the bottom steel mold through the inner steel mold and the reinforcing hanger. The weight of the precast groove bottom body is transferred to the bottom steel mold, so that the bottom of the precast groove bottom body does not need to be supported by multiple square timbers. This solves the problem that the bottom mold of the groove area is supported by multiple square timbers, which leads to the further occupation of the descent space. Attached Figure Description

Detailed Implementation

[0014] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0015] See Figure 1 As shown.

[0016] This application discloses a construction structure for opening holes at floor settlement points, comprising: The prefabricated groove bottom 1 is constructed by prefabrication, and positioning steel plates 11 are pre-embedded at both ends of the prefabricated groove bottom 1.

[0017] The precast groove bottom 1 with positioning steel plate 11 has L-shaped cast-in-place bodies 2 at both ends. The vertical section of the cast-in-place body 2 and the precast groove bottom 1 form a floor settlement groove. The precast groove bottom 1 has pre-embedded connecting bars 12 that extend into the cast-in-place body 2. The precast groove bottom 1 and the cast-in-place body 2 are connected by the connecting bars 12.

[0018] The positioning steel plates 11 at both ends of the precast groove bottom 1 are welded and fixedly connected to the inner steel mold 3 and the bottom steel mold 4. The inner steel molds 3 are supported by telescopic rods 31.

[0019] The bottom of the horizontal section of the bottom steel mold 4 has a support rod 41 for support; the top of the inner steel mold 3 is fixedly connected to a reinforcing rod 5 by bolts, and the two ends of the reinforcing rod 5 are connected to the horizontal section of the bottom steel mold 4 by through bolt assemblies 6; the cast-in-place body 2 corresponding to the through bolt assembly 6 has a pre-embedded opening sleeve 61, which forms an opening for the screw body of the through bolt assembly 6 to pass through.

[0020] During the casting of the cast-in-place body 2, the vertical section of the cast-in-place body 2 is cast through the casting space formed by the inner steel mold 3, the vertical section of the bottom steel mold 4, and the precast groove bottom body 1. The top of the precast groove bottom body 1 is connected and limited to the vertical section of the bottom steel mold 4 through the positioning steel plate 11. The top of the precast groove bottom body 1 is connected and limited to the horizontal section of the bottom steel mold 4 through the inner steel mold 3 and the reinforcing hanger 5. The weight of the precast groove bottom body 1 is transferred to the bottom steel mold 4, so that the bottom of the precast groove bottom body 1 does not need to be supported by multiple square timbers. This solves the problem that the bottom mold of the groove area is supported by multiple square timbers, which leads to the further occupation of the descending space.

[0021] This application discloses a construction process for treating floor settlement in prefabricated buildings, particularly a construction process for creating openings at floor settlement points, comprising the following steps: The bottom steel mold 4 is supported by the support rod 41. The reinforcing hanger 5 is connected to the horizontal section of the bottom steel mold 4 by the through bolt assembly 6. The inner steel mold 3 is connected to the reinforcing hanger 5. The two ends of the positioning steel plate 11 of the precast groove bottom 1 are welded and fixed to the bottom steel mold 4 and the inner steel mold 3, so that the precast groove bottom 1 is fixedly connected to the bottom steel mold 4 and the inner steel mold 3 and bears the force. The bottom of the precast groove bottom 1 does not need to be supported. Concrete is poured into the pouring space formed by the inner steel mold 3, the vertical section of the bottom steel mold 4 and the precast groove bottom 1 to form the cast-in-place body 2. At this time, the cast-in-place body 2 and the precast groove bottom 1 are connected and assembled by the connecting bar 12. The vertical section of the cast-in-place body 2 and the precast groove bottom 1 form a floor settlement groove.
