Description

Technical Field

[0001] This utility model relates to the field of building construction, and more specifically, to a pre-embedded structure for a medical track opening, a floor slab casting structure, and a multi-story medical building. Background Technology

[0002] In recent years, intelligent rail logistics systems have been rapidly gaining popularity in specialized buildings within certain industries. These systems integrate automation and information technology for efficient material transport and are commonly used in hospitals, nursing homes, electronics factories, and other locations with stringent environmental requirements and high demand for material flow. These systems not only significantly improve the efficiency and accuracy of material distribution and reduce labor costs, but also effectively isolate external environmental interference from internal work areas. Their importance has become even more pronounced during pandemics.

[0003] However, the installation and deployment of intelligent rail logistics systems, especially in the preparatory work during the building structure construction phase, faces numerous challenges. The reservation of large-diameter openings (square openings with sides approximately 1.6 meters long) is fundamental to system installation, far exceeding the size range of openings reserved in conventional building construction, thus placing higher demands on building structure design and construction. Traditionally, these openings are reserved by civil engineering construction units at the initial stage of construction, adhering to strict building construction specifications and using materials such as steel bars to reinforce the surrounding structure to ensure the safety and stability of the building structure. However, in practice, the installation of intelligent rail logistics systems involves multiple stages, including opening reservation, structural reinforcement, safety protection, vertical deviation correction, and track installation and fixing. These processes are often completed in stages by different specialized construction units, with close interdependence and mutual influence among them. This fragmented operation mode not only leads to complex construction processes and high coordination difficulties but also often results in a series of problems such as low construction efficiency, cost overruns, frequent rework, and liability disputes due to poor information communication, inconsistent standards, and unclear responsibilities. Construction companies often rely on experience to make judgments during construction, making it difficult to ensure consistency in construction quality and schedule. This situation not only increases the difficulty of project management but also limits the rapid replication and promotion of intelligent rail logistics systems in different projects. Utility Model Content

[0004] This utility model aims to overcome at least one defect in the prior art and provides a pre-embedded structure for medical track openings, which solves the problem of complicated and difficult-to-coordinate installation procedures in intelligent track logistics systems.

[0005] The technical method adopted in this utility model is a pre-embedded structure for a medical track opening, comprising:

[0006] The main frame is designed to surround the track passage and forms a passageway in the middle;

[0007] The joining structure is set on the main frame body, with one end connected to the main frame body and the other end extending outward from the main frame body;

[0008] The frame body has a material receiving cavity on at least one side, and the material receiving cavity has a horizontally outward feeding port.

[0009] During the construction phase of the building structure, the pre-embedded structure is embedded in the opening for installing the intelligent rail logistics system, and welded to the structural steel bars around the opening. Concrete is filled around the pre-embedded structure and into the material cavity of the pre-embedded structure. After the concrete solidifies, the pre-embedded structure is fixed in the building structure, which plays a role in stabilizing the building structure and reinforcing the opening.

[0010] To maintain the stability of the main frame, the main frame includes several corner structures, several connecting structures, and connectors. The corner structures are spaced apart, and the connecting structures connect adjacent corner structures through the connectors to form a ring. Under the action of the connectors, the connecting structures and corner structures are connected to form a strong and stable ring. This type of frame structure can effectively reinforce building openings, forming a unified load-bearing structure to prevent opening collapse. It also leaves space for laying logistics tracks, reducing the number of steps required for pre-reserving openings, lowering costs, and reducing manpower consumption.

[0011] To ensure the reinforcement effect of the opening, the corner structure includes: a first material-containing cavity and a second material-containing cavity; the lower extension of the first material-containing cavity and the second material-containing cavity extends horizontally outward to form a welding edge;

[0012] The first material receiving cavity includes: a first feed inlet that is horizontally outward, and a second feed inlet that opens on the side away from the second material receiving cavity;

[0013] The second material container includes: a third feed inlet that faces outward horizontally, and a fourth feed inlet that opens on the side away from the first material container;

[0014] The corner structure also includes an extension plate, which is connected to the second feed inlet. The connecting structure is connected to the corner structure through the extension plate. When installing the embedded structure into the reserved opening in the building structure, concrete is filled around the embedded structure and is filled into the first and second material cavities from the first and third feed inlets. When the concrete solidifies, the embedded structure is fixed in the opening, thus reinforcing the opening.

[0015] To facilitate replacement, the connecting structure is provided with a third material receiving cavity that extends through both ends, and the third material receiving cavity is connected to the first material receiving cavity and the second material receiving cavity respectively;

[0016] The epitaxial wafer extends into the third material cavity;

[0017] The connector includes an extension post and a locking element. The extension post passes sequentially through the connecting structure and the corner structure from the opening into the third material cavity. The locking element is mounted on the extension post to clamp the connecting structure and the corner structure from both sides. The extension post and locking element lock the corner structure and the connecting structure. When the corner structure and / or the connecting structure is damaged, the extension post and locking element can be released to separate the corner structure and the connecting structure, replace the damaged part, and then lock it back in place using the extension post and locking element, facilitating installation and replacement.

[0018] To ensure accurate positioning and facilitate the installation of the embedded structure, the corner structure includes: a top plate, a bottom plate, and a connecting plate connecting the top plate and the bottom plate;

[0019] The joining structure includes: an upper connecting post and a lower connecting post;

[0020] The base plate is provided with a downwardly extending lower connecting post and / or positioning post;

[0021] The top slab is equipped with an upwardly extending upper connecting column. When the embedded structure is applied to a multi-story building structure, after the embedded structure of the upper floor is installed, a plumb bob is installed on the upper connecting column of the lower embedded structure. The plumb bob emits a laser to align with the positioning column of the upper embedded structure, thus completing the positioning of the embedded structure. After all the embedded structures are installed, the track is fixed in place by the upper and lower connecting columns of the upper and lower embedded structures, thus realizing the track laying.

[0022] The surface of the corner structure is provided with a locking tab, which forms a locking opening facing the side of the opening;

[0023] A gap is left between the locking piece and the top plate to form a locking groove;

[0024] The outer edge of the locking piece on the side away from the opening extends downward and connects to the corner structure.

[0025] To ensure safety and facilitate easy installation at the opening, the main frame is equipped with a vertically extending fence.

[0026] The fence includes: uprights connected to the corner structure, and horizontal bars connecting two adjacent uprights;

[0027] One end of the upright is provided with a connecting piece. The upright engages with the locking piece via the connecting piece, such that the locking opening abuts against one side of the upright and one side of the connecting piece is inserted into the locking groove. The connecting piece passes through the upper connecting post and is inserted into the locking groove by a nut, making the connecting piece more stably connected to the frame body. Through the engagement of the connecting piece, the upper connecting post, and the nut, the fence is fixed to the frame body.

[0028] A floor slab casting structure includes: a closed receiving formwork for receiving concrete, and a pre-embedded structure for a medical track opening as described above; the pre-embedded structure is disposed on the closed receiving formwork. When filling concrete around the pre-embedded structure, the closed receiving formwork is fixed to the bottom surface of the floor slab to be installed, the pre-embedded structure is placed on the closed receiving formwork, floor slab concrete is poured around the steel structure pre-embedded component of the reserved opening, and the closed receiving formwork supports the concrete and the pre-embedded structure; after the concrete has solidified, the closed receiving formwork is removed, completing the installation of the pre-embedded structure.

[0029] For ease of installation, the main body of the steel structure frame of the opening is placed on the surface of the template and welded and fixed to the surrounding steel bars;

[0030] The main frame includes: several corner structures, several connecting structures, and connectors; the corner structures are spaced apart, and the connecting structures connect adjacent corner structures through the connectors to form a ring;

[0031] The corner structure includes: a top plate, a bottom plate, and a connecting plate connecting the top plate and the bottom plate;

[0032] The joining structure includes: an upper connecting post and a lower connecting post;

[0033] The base plate is provided with a downwardly extending lower connecting post and a positioning post;

[0034] The top plate is provided with an upwardly extending upper connecting column;

[0035] The closed receiving template is provided with mating holes;

[0036] The lower connecting post and the positioning post have a lower extension depth greater than the thickness of the closed receiving template, so that the lower ends of the lower connecting post and the positioning post extend to the bottom of the closed receiving template.

[0037] The lower connecting column is also equipped with a removable protective sleeve. During the installation of the embedded structure, the embedded structure is placed on the closed receiving template, and the lower connecting column and positioning column pass through the mating holes of the closed receiving template to prevent the embedded structure from shifting on the closed receiving template. The part of the lower connecting column that passes through the closed receiving template is covered with a protective sleeve to prevent the lower connecting column from being contaminated by concrete. When installing the logistics track later, the protective sleeve can be removed to fix the track.

[0038] A multi-story medical building includes a track passage penetrating at least two floors, with a pre-embedded structure for the aforementioned medical track opening on each floor. When installing the first pre-embedded structure, a closed support template is fixed to the bottom surface of the floor to be installed. The pre-embedded structure is placed on the closed support template, with a lower connecting column and a positioning column passing through mating holes in the closed support template to prevent the pre-embedded structure from shifting on the template. A protective sleeve is fitted over the lower connecting column portion passing through the closed support template. When filling concrete around the pre-embedded structure, concrete is filled into the gap between the pre-embedded structure and the reserved opening, with the closed support template supporting the uncured concrete and the pre-embedded structure. After the concrete has cured, the closed support template is removed, completing the installation of the first pre-embedded structure. When installing other pre-embedded structures, a plumb line is installed on the upper connecting piece of the pre-embedded structure. The laser emitted by the plumb line is aligned with the positioning column of the upper pre-embedded structure to determine the position of the pre-embedded structure. After determining the position of the pre-embedded structure, it is installed in the same manner as the first pre-embedded structure.

[0039] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0040] 1. Prefabricated embedded parts are made of channel steel according to the opening size. During the construction of the floor slab structure, they are directly embedded into the building structure, which effectively ensures the quality of the building structure and avoids the cumbersome process of making structural beams with steel bars on the construction site.

[0041] 2. The upper and lower end faces of the embedded part are equipped with vertical positioning devices. During construction, a plumb line can be directly installed on the embedded part of the next floor slab to measure and position the embedded part of the next floor, which simplifies the measurement work, reduces measurement errors, and ensures the verticality of the shaft.

[0042] 3. The upper surface of the embedded part is equipped with a railing connection port, which can be connected by plug-in or bolt connection. The railing is quick and easy to install, avoiding the traditional method of fixing with expansion bolts in the concrete floor slab. It can provide good safety protection during the construction and later operation stages.

[0043] 4. Convenient installation of logistics tracks. Previously, before installing tracks, it was necessary to first position them on the floor slab, then use expansion bolts to fix the track brackets, and finally install the tracks. With this embedded part, the brackets and tracks can be directly assembled between the embedded parts on the upper and lower floors, which is simple and quick. During installation, the position of the track installation can be finely adjusted through bolt adjustment, avoiding secondary damage to the structure caused by expansion bolts.

[0044] 5. It is conducive to the standardization of construction techniques. Attached Figure Description

[0054] The technical methods of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0055] Example 1

[0056] like Figure 1 As shown in the figure, the pre-embedded structure for a medical track opening provided in this embodiment includes:

[0057] The frame body 100 is designed to surround the track channel and forms a passage opening in the middle. At least one side of the frame body 100 is provided with a material receiving cavity, and the material receiving cavity is provided with a horizontally outward feeding port.

[0058] The joining structure 300 is set on the frame body 100, with one end connected to the frame body 100 and the other end extending outward from the frame body 100;

[0059] The fence 200 is connected to the frame body 100 via the joint structure 200 and is used for the safety protection of the reserved opening.

[0060] When installing the embedded structure, concrete is filled into the gap between the frame body 100 and the reserved opening. The concrete is filled into the material cavity from the feed port. After the concrete solidifies, the embedded structure is fixed at the reserved opening. The frame body 100 reinforces the opening, eliminating the need for steel reinforcement. The fence 200 activates the opening protection function, eliminating the need for subsequent safety protection of the opening.

[0061] In this embodiment, as Figure 2 As shown, the frame body 100 includes a connecting structure 110, corner structures 120, and connectors 130. The corner structures 120 are spaced apart, and under the action of the connectors 130, the connecting structure 110 connects two adjacent corner structures 120 to form a ring. This frame body 100 structure can effectively reinforce building openings and prevent them from collapsing. Furthermore, the ring-shaped frame also provides space for laying logistics tracks, reducing the need for later maintenance of the openings, lowering costs, and reducing manpower consumption. In addition, the connection method using connectors 130 facilitates disassembly, assembly, and replacement of parts.

[0062] In this embodiment, as Figure 3 and 4As shown, the corner structure 120 is an L-shaped metal part with the L-shaped opening facing the hole. The corner structure 120 includes: a top plate 121, a bottom plate 122, and a connecting plate 123 connecting the top plate 121 and the bottom plate 122. The top plate 121, the bottom plate 122, and the connecting plate 123 are connected to form a first material receiving cavity 127 and a second material receiving cavity 128. The lower extensions of the first material receiving cavity 127 and the second material receiving cavity 128 extend horizontally outward to form a welding edge 126. The material receiving cavity includes: a first feed inlet that is horizontally outward, and a second feed inlet that opens on the side away from the other material receiving cavity. When installing the embedded structure into the reserved opening in the building structure, concrete is filled around the frame body 100 of the embedded structure. Since the corner structure 120 has a first material cavity 127 and a second material cavity 128 on its outer side, the filling concrete is filled into the first material cavity 127 and the second material cavity 128 from the first feed port and the third feed port. When the concrete solidifies, the embedded structure is fixed in the opening, which serves to fix the embedded structure and reinforce the opening. The corner structure 120 also includes an extension piece 124, which is connected to the second feed port. The connecting structure 110 is a C-shaped structure, and the opening of the C-shaped structure is the third material cavity. The third material cavity runs through both ends. The connecting structure 110 is connected to the corner structure 120 through the extension piece 124. That is, the third material cavity is connected to the first material cavity and the second material cavity respectively, and the extension piece 124 extends into the third material cavity. When filling concrete around the embedded structure, the concrete fills the first and second material cavities of the corner structure 120 and the third material cavity of the connecting structure 110. The gap between the frame body 100 and the reserved opening is filled. After the concrete has completely solidified, the embedded structure installation is completed.

[0063] In this embodiment, as Figure 5 As shown, the connector 130 includes an extension post 131 and a locking member 132. The extension post 131 passes sequentially through the connecting structure 110 and the corner structure 120 from the opening and enters the third material receiving cavity. The locking member 132 is disposed on the extension post 131 to clamp the connecting structure 110 and the corner structure 120 from both sides. When the corner structure and / or the connecting structure is damaged, the extension post 131 and the locking member 132 are released to separate the corner structure 120 and the connecting structure 110, the damaged part is replaced, and then the extension post 131 and the locking member 132 are used to lock it back in place, facilitating installation and replacement.

[0064] In this embodiment, as Figure 6As shown, the connecting structure 300 includes an upper connecting column 310 and a lower connecting column 320. The upper connecting column 310 is mounted on the top plate 121 and extends upwards, while the lower connecting column 320 is mounted on the bottom plate 122 and extends downwards. Additionally, a positioning column 330 is also mounted on the bottom plate 122 and extends downwards. A conversion piece 311 can be fitted onto the upper connecting column 310 to convert the original plug-in connection to a bolt connection. When the embedded structure is used in a multi-story building structure, after the embedded structure of the upper floor is installed, a plumb bob is installed on the upper connecting column 310 of the lower embedded structure. The plumb bob emits a laser to align with the positioning column 330 of the upper embedded structure, thus completing the positioning of the embedded structure. After all the embedded structures are installed, the track is fixed in place by the upper connecting columns 310 and lower connecting columns 320 of the upper and lower embedded structures, thus completing the track laying.

[0065] In this embodiment, as Figure 3 and 7 As shown, the top plate of the corner structure 120 is provided with a locking piece 125, which forms a locking opening facing the opening. A gap is left between the locking piece 125 and the top plate 125 to form a locking groove. The outer edge of the locking piece 125 away from the opening extends downwards and connects to the top plate 121 of the corner structure 120. For safety protection and easy installation of the opening, the frame body 100 is provided with a vertically extending fence 200. The fence 200 includes uprights 210 connected to the corner structure 120 and horizontal bars 220 connecting adjacent uprights 210. One end of the upright 210 is provided with a connecting piece 230. The upright 210 engages with the locking piece 125 of the corner structure 120 through the connecting piece 230. One side of the connecting piece 230 is inserted into the locking groove, so that the locking opening abuts against one side of the upright 210. The connecting piece 230 passes through the upper connecting post 310 and is fixed by the locking member 132 so that the connecting piece 230 is inserted into the locking groove, making the connecting piece 230 more stably connected to the frame body 110. Through the cooperation of the connecting piece 230, the upper connecting post 310 and the locking member 132, the fence 200 can be easily installed on the frame body 100 to activate the function of opening protection.

When filling concrete around the pre-embedded structure, the closed receiving formwork 400 is fixed to the bottom surface of the floor to be installed, the pre-embedded structure is placed on the closed receiving formwork 400, and concrete is filled into the gap between the pre-embedded structure and the reserved opening. The closed receiving formwork 400 supports the concrete and the pre-embedded structure; after the concrete has solidified, the closed receiving formwork 400 is removed, completing the installation of the pre-embedded structure.

[0068] Combination Figure 1-8 As shown, the frame body 100 is connected to the surface of the 400 closed receiving template. The frame body 100 includes: several corner structures 120, several connecting structures 110, and connectors 130; the corner structures 120 are spaced apart, and the connecting structures 110 connect adjacent corner structures 120 through connectors 130 to form a ring.

The closed receiving template 400 is provided with mating holes. The lower connecting column 320 and the positioning column 330 extend to a depth greater than the thickness of the closed receiving template 400, so that the lower ends of the lower connecting column 320 and the positioning column 330 extend below the closed receiving template 400. The lower connecting column 320 is also provided with a removable protective sleeve 321. When installing the embedded structure, the embedded structure is placed on the closed receiving template 400, and the lower connecting column 320 and the positioning column 330 pass through the mating holes of the closed receiving template 400 to prevent the embedded structure from shifting on the closed receiving template 400. The portion of the lower connecting column 320 that passes through the closed receiving template 400 is covered with a protective sleeve 321 to prevent the lower connecting column 320 from being contaminated by concrete. When it is necessary to install the logistics track, the protective sleeve 321 can be removed to fix the track.

[0069] Example 3

[0070] A multi-story medical building includes a track channel that runs through at least two floors, with a pre-embedded structure for a medical track opening as described in Example 2 provided on the floor. When installing the first embedded structure, the closed support template 400 is fixed to the bottom surface of the floor to be installed. The embedded structure is placed on the closed support template 400. The lower connecting column 320 and the positioning column 330 pass through the mating holes of the closed support template 400 to prevent the embedded structure from shifting on the closed support template. A protective sleeve 321 is fitted over the part of the lower connecting column 320 that passes through the closed support template 400. When filling concrete around the embedded structure, concrete is filled into the gap between the embedded structure and the reserved opening. The closed support template 400 supports the uncured concrete and the embedded structure. After the concrete has cured, the closed support template 400 is removed, and the installation of the first embedded structure is completed. When installing other embedded structures, a plumb bob is installed on the upper connecting piece 310 of the embedded structure. The laser emitted by the plumb bob is aligned with the positioning column 330 of the upper embedded structure to determine the position of the embedded structure. After determining the position of the embedded structure, the embedded structure is installed in the same way as the first embedded structure.

One side of the fence of the pre-embedded structure extends to the upper pre-embedded structure and connects to the frame body 100 of the upper pre-embedded structure. The track 500 is laid on the side of the fence 200 connected to the frame body 100 of the upper pre-embedded structure, and the fence 200 serves a fixing and protective function. A gap is reserved between the track 500 and the other side of the fence 200, large enough for a logistics rail transport vehicle to pass through, transporting medical supplies along the track 500.
