Description

Technical Field

[0001] The utility model relates to the technical field of assembled buildings, in particular to an assembled corridor structure. Background Art

[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories, where building components and accessories are processed and manufactured, transported to the construction site, and assembled and installed on site through reliable connection methods. A corridor is a building structure that connects two towers. The corridor usually consists of two parts: corridor beams and corridor slabs.

[0003] In the prior art, reserved steel bars extend from the sides of the corridor slab and the top of the corridor beam. The prefabricated corridor slab is moved to the corridor beam by hoisting, so that the two groups of steel bars are staggered with each other, and then the staggered part of the steel bars is enclosed by a formwork, and then concrete is poured into the formwork. After the concrete solidifies, the formwork is disassembled to form a connection. The assembly and connection method of the corridor slab and the corridor beam under this prefabricated structure is relatively troublesome, and more cast-in-place concrete is required, and more wet operations are required. Therefore, an assembled corridor structure is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an assembled corridor structure to solve the above-mentioned deficiencies in the prior art.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] An assembled corridor structure comprises two beams arranged in parallel and at intervals and a prefabricated plate body spanning and overlapping the two beams, and also comprises: a positioning rib, which is movably arranged at the upper end of the beam body; a connecting hole, which is opened on the prefabricated plate body and corresponds to the positioning rib, and a hook portion is arranged therein, and a groove is arranged on the hook portion, the positioning rib is inserted into the connecting hole and the upper end is bent and embedded in the groove; the connecting hole is used to fill slurry; a tensioning assembly, which is arranged in the beam body and is used to tighten the positioning rib downward.

[0007] Preferably, a box body is arranged in the beam body, a sleeve penetrating the top surface of the beam body is arranged at the upper end of the box body, the positioning rib is movably arranged through the sleeve, and the tensioning assembly is arranged in the box body.

[0008] Preferably, the tensioning assembly comprises a floating plate which can be lifted and lowered in the box body, a spring is connected between the upper end of the floating plate and the top surface of the box body, and the lower end of the positioning rib passes through the spring and is rotatably connected to the floating plate.

[0009] Preferably, a patch is provided at the lower end of the positioning rib, and damping patterns are provided on the bottom surface of the patch and the inner bottom surface of the box body.

[0010] Preferably, a plurality of supports extending horizontally toward the outside of the prefabricated board body are sandwiched between the beam body and the prefabricated board body, and guardrails are installed on the supports.

[0011] Preferably, the upper end of the beam body and the bottom surface of the prefabricated plate body are provided with matching stepped grooves, and the support is provided with a T-shaped block matching the stepped grooves.

[0012] In the above technical solution, the beneficial effects of the utility model are:

[0013] The assembled corridor structure is provided with positioning ribs and connecting holes. When the prefabricated panel is erected on the beam, the positioning ribs are inserted into the connecting holes. Then, the positioning ribs are pulled up and rotated so that the bent portion of the upper end corresponds to the top of the hook portion, and then embedded into the groove under the downward tightening action of the tensioning assembly. In this way, the beam and the prefabricated panel are initially fixed, and then slurry is poured into the connecting holes. When the slurry has not solidified, the initial fixation of the positioning ribs and the connecting holes can prevent connection defects caused by accidental displacement of the prefabricated panel. After the slurry solidifies, the connection between the beam and the prefabricated panel is completed. This arrangement eliminates the need to set up additional supports and formwork during construction, thereby improving construction efficiency. In addition, only cast-in-place operations in the connecting holes need to be performed during on-site construction, and wet operations are greatly reduced, which is more energy-saving and environmentally friendly.

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] See also Figure 1-9 An assembled corridor structure provided by an embodiment of the utility model includes two parallel and spaced beams 1 and a prefabricated plate 2 spanning and overlapping the two beams 1, and also includes: a positioning rib 3, which is movably arranged at the upper end of the beam 1; a connecting hole 4, which is opened on the prefabricated plate 2 and corresponds to the positioning rib 3, and a hook portion 5 is arranged therein, and a groove 6 is arranged on the hook portion 5, the positioning rib 3 is inserted into the connecting hole 4 and the upper end is bent and embedded in the groove 6; the connecting hole 4 is used to fill slurry; a tensioning component, which is arranged in the beam 1 and is used to tighten the positioning rib 3 downward.

[0030] Specifically, the beam body 1 is a concrete steel structure; the precast panel body 2 is prefabricated in a factory and then assembled at the construction site; the precast panel body 2 is a concrete panel, and a steel mesh is arranged within the thickness of the concrete panel, and the connection holes 4 are arranged to avoid the steel mesh; for a long corridor building, the precast panel body 2 is formed in the form of multiple end-to-end splicing to form a whole corridor panel, and all are supported between two beam bodies 1, and at the same time, the supported part of the precast panel body 2 corresponds to the area where the connection holes 4 are arranged. The connection holes 4 are arranged in two rows corresponding to the two beam bodies 1, and the preferred number of connection holes 4 in each row is 2-5. The positioning rib 3 is arranged in the connecting hole 4 near the center of the connecting hole 4; the length of the bend of the upper end of the positioning rib 3 is less than the inner radius of the connecting hole 4; the hook portion 5 is a protruding structure of the inner wall of the connecting hole 4, and the protruding range does not exceed the center of the connecting hole 4, and a gap is arranged between the upper end of the hook portion 5 and the upper end of the connecting hole 4; the groove 6 is arranged at the upper end of the hook portion 5, and the extension direction is perpendicular to the axis of the connecting hole 4; the connecting hole 4 is filled with high-strength castable, such as high-strength concrete slurry with a strength grade of more than C60, and due to the arrangement of the hook portion 5 in the connecting hole 4, the slurry that is solidified and fixed in the connecting hole 4 is larger at the top and smaller at the bottom, which can firmly limit the prefabricated plate body 2 on the beam body 1; the tensioning component elastically tightens the positioning rib 3 downward, and the positioning rib 3 can passively rise under the action of external force, and the positioning rib 3 can rotate freely. In actual use of this technical solution, the precast panel 2 is moved to the beam body 1 by lifting, so that each connection hole 4 corresponds to each positioning rib 3 one by one, and the positioning rib 3 rotates to avoid the bent upper end of the hook portion 5, and then the precast panel 2 is moved down and laid on the two beam bodies 1, and the positioning rib 3 is inserted into the connection hole 4, and then the positioning rib 3 is pulled up and rotated so that the bent part of its upper end corresponds to the groove 6 above the hook portion 5, and then the positioning rib 3 is loosened. Under the tensioning assembly, the upper end of the positioning rib 3 is bent and embedded in the groove 6, thereby preliminarily fixing the beam body 1 and the precast panel 2, and then pouring slurry into the connection hole 4. When the slurry has not solidified, the preliminary fixation of the positioning rib 3 and the connection hole 4 can prevent connection defects caused by accidental displacement of the precast panel 2, and after the slurry solidifies, the connection between the beam body 1 and the precast panel 2 is completed.

[0031] Compared with the prior art, the assembled corridor structure proposed in the embodiment of the utility model is provided with positioning ribs 3 and connecting holes 4. When the prefabricated panel 2 is erected on the beam body 1, the positioning ribs 3 are inserted into the connecting holes 4, and then the positioning ribs 3 are pulled up and rotated so that the bent part of the upper end corresponds to the top of the hook portion 5, and then embedded in the groove 6 under the downward tightening action of the tensioning assembly, thereby the beam body 1 and the prefabricated panel 2 can be initially fixed, and then slurry is poured into the connecting holes 4. When the slurry is not solidified, the initial fixation of the positioning ribs 3 and the connecting holes 4 can prevent connection defects caused by accidental deviation of the prefabricated panel 2, and after the slurry is solidified, the connection between the beam body 1 and the prefabricated panel 2 is completed. This arrangement eliminates the need to set up additional supports and formworks during construction, thereby improving construction efficiency, and only cast-in-place operations in the connecting holes 4 are required during on-site construction, and wet operations are greatly reduced, which is more energy-saving and environmentally friendly.

[0032] As a preferred technical solution of this embodiment, a box body 7 is provided in the beam body 1, and a sleeve 8 is provided on the upper end of the box body 7 and passes through the top surface of the beam body 1. The positioning bar 3 is movable through the sleeve 8, and the tensioning assembly is arranged in the box body 7. Specifically, the outer side of the sleeve 8 is gripped by the concrete entity of the beam body 1, so as not to affect the up and down movement and rotation of the positioning bar 3 in the sleeve 8. The box body 7 is fixed in the steel skeleton of the beam body 1 during the prefabrication process of the beam body 1, and then anchored in the beam body 1 when the beam body 1 is cast into concrete; the tensioning assembly is arranged in the box body 7, which can avoid affecting the appearance of the beam body 1 and reduce additional construction calculations.

[0033] As the preferred technical solution of this embodiment, the tensioning assembly includes a floating plate 9 that can be raised and lowered in the box body 7, a spring 10 is connected between the upper end of the floating plate 9 and the inner top surface of the box body 7, the lower end of the positioning rib 3 passes through the spring 10 and is rotatably connected to the floating plate 9, specifically, an annular groove is provided at the lower end of the positioning rib 3, and a through hole matching the annular groove is opened on the floating plate 9, so that the floating plate 9 can be rotatably connected to the lower end of the positioning rib 3, and can be raised and lowered synchronously with the positioning rib 3 without affecting the free rotation of the positioning rib 3; the elastic force of the spring 10 keeps pushing the floating plate 9 away from the inner top surface of the box body 7 without being affected by external forces, so that the lower end of the positioning rib 3 is close to the inner bottom surface of the box body 7, and the height of the upper end of the positioning rib 3 extending out of the upper surface of the beam body 1 is minimized.

[0034] As a further preferred technical solution of this embodiment, a patch 11 is provided at the lower end of the positioning rib 3, and damping patterns are provided on the bottom surface of the patch 11 and the inner bottom surface of the box body 7. Specifically, the damping patterns are radially star-shaped, and the two damping patterns fit together to limit the rotation of the patch 11 relative to the inner bottom surface of the box body 7; when the spring 10 is not subject to external force, the lower end of the positioning rib 3 is close to the inner bottom surface of the box body 7, that is, the lower end of the positioning rib 3 drives the patch 11 to fit the inner bottom surface of the box body 7, thereby making the two damping patterns fit together, and then the rotation of the positioning rib 3 can be limited, which is convenient for first positioning the rotation position of the positioning rib 3 when the prefabricated plate 2 is assembled.

[0035] In another embodiment of the utility model, a plurality of supports 12 extending horizontally to the outside of the precast panel 2 are sandwiched between the beam body 1 and the precast panel body 2, and a guardrail 13 is installed on the support 12. Specifically, the protective structure on the side of the existing corridor is often set on the upper surface of the corridor, which will occupy the area of ​​the corridor. In this technical solution, the support 12 is set on the side of the precast panel 2, and the guardrail 13 is set on the support 12 to avoid the upper surface of the precast panel 2, thereby eliminating the problem of the protective structure occupying the corridor area.

[0036] As the preferred technical solution of this embodiment, a matching step groove 14 is provided at the upper end of the beam body 1 and the bottom surface of the precast panel body 2, and a T-shaped block 15 matching the step groove 14 is provided on the support 12. Specifically, when the precast panel body 2 fits the beam body 1, the corresponding step grooves 14 above and below can form a T-shape, and the T-shaped block 15 is embedded in the step groove 14 with its head, and its tail extends horizontally out of the side of the precast panel body 2 and is fixedly connected to the support 12. Furthermore, under the gravity of the precast panel body 2 and the connection between the precast panel body 2 and the beam body 1 formed by the positioning rib 3 and the connecting hole 4, the T-shaped block 15 can be stably limited in the step groove 14 without the need for other fixing parts. A connecting ear can be provided at the lower end of the guardrail 13 to correspond to the support 12, and then connected by bolts or welding.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
