Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a fully prefabricated foundation beam structure. Background Technology

[0002] The foundation beam is the bottom load-bearing beam of the mobile home. It is formed by erecting side formwork on strip footings and then casting it in place. During the cast-in-place construction of the foundation beam, it is necessary to pre-embed reinforcing bars for connection to the precast wall panels. The size of the pre-drilled holes in the PK boxes of the fully assembled precast wall panels is limited, therefore, the accuracy of the pre-drilled reinforcing bars in the foundation beam is crucial. Due to the narrow working surface during the foundation beam pouring process, workers repeatedly step on the wooden formwork used to position the reinforcing bars, causing the formwork to shift or break, resulting in misaligned reinforcing bars and difficulties in hoisting and lowering the precast wall panels.

[0003] Furthermore, during exterior wall decoration construction, because the precast exterior walls are connected to the foundation beams, and since the precast wall panels and foundation beams are assembled without plastering, the accuracy requirements for the top width of the foundation beams are relatively high. On-site, misalignment between the precast wall panels and the foundation beams frequently occurs, necessitating plastering on the foundation beam surface during exterior wall panel decoration construction. This increases construction costs and delays the project schedule. Utility Model Content

[0004] The purpose of this utility model is to provide a fully assembled foundation beam structure that avoids misalignment of reinforcing bars and misalignment between precast wall panels and foundation beams.

[0005] The technical solution of this utility model is: a fully assembled foundation beam structure, including strip base, side formwork, positioning ribs, inserts, and long nails. The upper end of the strip base is provided with a slot. Two side formworks are arranged at intervals in the width direction X of the slot. The positioning ribs are covered on the upper ends of the two side formworks, and multiple positioning ribs are arranged in the length direction Y of the strip base. The positioning ribs are fixed to the side formworks by long nails. Insert holes are provided on the positioning ribs for the inserts to pass through. A part of the insert extends into the two side formworks, and the other part of the insert extends outward from the upper side of the positioning ribs.

[0006] Preferably, the lower surface of the positioning rib is provided with two baffles spaced apart, and the outer surface of the baffles is in contact with the inner surface of the side template.

[0007] Preferably, the fully assembled foundation beam structure further includes timber, with both ends of the positioning stiffener extending along the width direction X to the outside of the side formwork, the timber being installed on the lower surface of the positioning stiffener extending outward and the outer surface of the side formwork, and the positioning stiffener and the timber being fixed together by long nails.

[0008] Preferably, the fully assembled foundation beam structure further includes timber, with multiple timbers arranged along the height direction Z on the outer surface of the side formwork, and the timbers located at the lower end of the side formwork being embedded in the grooved sidewall of the strip base.

[0009] Preferably, the timber is the same length as the side template.

[0010] Preferably, the insert includes a screw and a nut threaded onto the screw, the screw passing through the insert hole, and the nut abutting against the upper surface of the positioning rib plate.

[0011] Preferably, the bottom of the strip base is provided with a pad layer.

[0012] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0013] 1. The fully assembled foundation beam structure has positioning plates for installing reinforcing bars on the top of the two side formworks, and the positioning plates are fixed to the side formworks with long nails. After the position of the positioning plates is fixed, the position of the reinforcing bars is also fixed. This effectively avoids the deviation of the reinforcing bars and ensures the accurate hoisting of the precast wall panels.

[0014] 2. The fully assembled foundation beam structure has positioning ribs on the top of the two side formworks for installing reinforcing bars, and the positioning ribs are fixed to the side formworks with long nails. The rigid positioning ribs limit the width of the upper end of the side formworks, thereby ensuring the width dimension of the top of the foundation beam, making the foundation beam have a good appearance quality, the beam top is straight, avoiding misalignment between the precast wall panels and the foundation beam, reducing plastering work, and ensuring the construction period.

[0018] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0019] like Figure 1 , Figure 2 As shown, the fully assembled foundation beam structure provided in this embodiment includes dowel bars 1, positioning ribs 3, long nails 4, foundation beams 5, side formwork 6, timber 7, strip foundations 8, and padding 9.

[0020] The padding layer 9 is placed on the ground, and the base strip 8 is placed on the upper surface of the padding layer 9. The base strip 8 has a groove in the middle, which extends and runs through the length Y direction of the base strip 8. The cross-section of the groove in the width X direction is U-shaped, and an insertion groove for embedding the timber 7 is provided at the bottom of the side wall of the base strip 8 where the groove is formed.

[0021] Two side templates 6 are spaced apart along the width direction X of the slot. The outer surface of the side template 6 is positioned close to the side wall of the slot formed by the strip base 8. Positioning ribs 3 are placed on the upper ends of the two side templates 6, and multiple positioning ribs 3 are arranged along the length direction Y of the strip base 8. Two baffles 31 are spaced apart on the lower surface of the positioning ribs 3, and the outer surface of the baffles 31 contacts the inner surface of the side template 6. The positioning ribs 3 are fixed to the side templates 6 by long nails 4.

[0022] The two ends of the positioning rib plate 3 extend along the width direction X to the outside of the side formwork 6. The timber 7 is installed on the lower surface of the positioning rib plate 3 extending outward and on the outer surface of the side formwork 6. The positioning rib plate 3 and the timber 7 are fixed together by long nails 4. The outer surface of the positioning rib plate 3 is flush with the outer surface of the timber 7. The timber 7 is also set on the outer surface of the middle part of the side formwork 6. The timber 7 is the same length as the side formwork 6.

[0023] The positioning rib plate 3 has insertion holes 2 for the insertion bars 1 to pass through. The insertion bar 1 includes a screw rod 11 and a nut 12 threaded onto the screw rod 11. The screw rod 11 passes through the insertion hole 2, and a portion of the screw rod 11 extends into the two side formworks 6. The stirrups between the screw rod 11 and the side formworks 6 form the foundation beam 5 after concrete is poured. The other portion of the screw rod 11 extends outward from the upper side of the positioning rib plate 3 for positioning the precast wall panel. The nut 12 abuts against the upper surface of the positioning rib plate 3.

[0024] The fully assembled foundation beam structure of this utility model greatly improves the accuracy of reinforcing bar verification after concrete pouring, resulting in a good appearance quality of the foundation beam, a straight beam top, and no misalignment when splicing with precast wall panels. It also reduces the number of plastering steps for the foundation beam and speeds up the construction progress of the exterior wall decoration.
