[0001] The utility model relates to the technical field of beam cage mold structures for connecting composite plates with cross beams, in particular to a beam cage mold structure for casting cross beams that is convenient for connecting composite plates. Background Art

[0002] With the rapid development of prefabricated building construction, the construction of composite slabs has been extensively studied and promoted, and a large number of composite slab construction technologies have been formed.

[0003] For example: In order to solve the defects of tower crane occupying time too long, low efficiency of composite plate installation, high labor intensity and high cost, the patent announcement number is CN110700418B, and the patent name is a construction process of a composite plate installation trolley cooperating with a tower crane to install composite plates, which discloses the following steps: the trolley moves to the designated area below the composite plate installation position; the top support is adjusted to rise above the top surface of the beam-column structure, the tower crane lifts the composite plate, and places the composite plate on the top surface of the top support; the trolley moves to fine-tune the position of the composite plate; vertical poles are erected under the four corners of the composite plate; the top support descends, and the beam-column structure and the poles catch the composite plate; the top support continues to descend, the top support is separated from the composite plate, and the trolley moves to the bottom of the installation position of the next composite plate; steps one to five are repeated until the last composite plate of the floor; the tower crane lifts the trolley away from the construction floor; the tower crane lifts the last composite plate, and manually assists in installing it to the designated position.

[0004] Another example: In order to reduce the steel pipes and wooden planks required for the on-site support system, reduce labor, and save material and engineering costs, the patent announcement number is CN106193589B, and the patent name is Concrete Super-High and Heavy Beam and Composite Slab Composite Structure Support Method, which discloses the following: installing super-high and super-heavy frame beam support frames and installing composite slab support frames; using Bailey frames for super-high and super-heavy frame beam formwork support frames; installing the frame beam bottom formwork and installing the frame beam side formwork; setting composite slab support rods on both sides of the frame beam side formwork; installing the composite slab support frame after the beam reinforcement is tied; installing the composite slab special support rod; and installing the composite slab support I-beam on the top of the special support rod for the composite slab.

[0005] Another example: in order to solve the problem that after the steel cage is tied outside the prefabricated composite slab beam, the tied steel cage cannot be placed into the prefabricated composite slab beam; the main bars of the steel cage are arranged up and down along the reserved steel bars, and the steel cage has been tied before it reaches the bottom of the prefabricated composite slab beam, which solves the problem of inconvenient tying the steel bars at the bottom of the prefabricated composite slab beam. The patent publication number is CN116201373A, and the patent name is A prefabricated composite slab system beam erecting device and its construction method. It discloses a vertical lifting mechanism, and the lifting end of the vertical lifting mechanism is provided with a transverse telescopic mechanism for supporting the main bars of the prefabricated composite slab beam; two groups of the main bars are arranged up and down along the reserved steel bars, and the two groups of main bars arranged up and down are provided with beam stirrups to form a steel cage of the prefabricated composite slab beam.

[0006] It can be seen that a large number of technical studies have been carried out in the prior art during the installation and construction of composite panels, which have led to the formation of effective support for composite panels when they are installed between beam frame structures, reducing the raw materials of the support system, reducing labor intensity, and then reducing costs. At the same time, the technical obstacles that make it difficult to put the steel cage in the beam when installing the steel cage in the beam after the composite panel is installed have also been studied and solved. However, in the prior art, there is no report on how to improve the beam cage mold structure for beam construction when installing composite panels between the frames formed by beams and columns after the beam construction is completed in advance, and then installing the composite panels after the composite panels are installed, and then undergoing the post-beam concrete layer construction process, so as to improve the convenience and reduce the construction difficulty when installing the composite panels after casting the beams. Utility Model Content

[0007] Based on the above technical problems, the research team of the invention has conducted a project research from the perspectives of pre-casting the beam-column frame structure and then installing the composite slab between the beam frames, aiming at improving the convenience and stability of the installation and construction between the beams and the composite slabs, reducing the construction cost and simplifying the support system. It has provided a new construction process for the beam construction process and beam cage mold construction in the process of connecting the composite slabs and the beams, and then provided a beam cage mold structure for casting the beams that is convenient for the connection of the composite slabs.

[0008] The specific technical solutions are:

[0009] A beam cage mold structure is used for casting beams that are convenient for connecting composite plates, including a beam mold groove and a steel cage, the steel cage is placed in the beam mold groove, and a number of reinforcement bars are inserted into the steel cage; a number of blocking members are provided on the inner wall of the beam mold groove, and a number of protrusions are formed in the beam mold groove after the blocking members are installed on the inner wall of the beam mold groove; positioning holes and connecting positions are provided on the blocking members, and the connecting positions are used to install the blocking members on the inner wall of the beam mold groove; after the blocking members are installed on the inner wall of the beam mold groove, the two ends of the reinforcement bars can be inserted into the positioning holes.

[0010] A barrier is installed on the inner wall of the beam mold groove, so that the barrier is raised when installed on the inner wall of the beam mold groove; then, pick bars are inserted into the steel cage, and the two ends of the pick bars can be inserted into the positioning holes, so that after pouring concrete to form a beam, several installation position structures can be left on the beam. There are pick bar ends in the installation position structure, which is convenient for the subsequent installation of the composite plate in the frame structure constructed between the beams, so that the pick bars can pick and install the composite plate on the left and right sides of the beam, thereby ensuring the stability of the connection and installation of the composite plate and the beam.

[0011] Specifically, after the beam cage formwork structure is cast to obtain the crossbeam, the crossbeam and the composite plate are installed in the following manner:

[0012] A fixed reinforcement structure corresponding to the installation position is led out on the composite plate, and the fixed reinforcement is connected to the steel bars in the composite plate (for example, in contact, hooked, or tied) to form a whole, and it is ensured that the fixed reinforcement is not easy to fall off from the composite plate. The composite plate is then hoisted into the frame constructed by the beam by a crane, so that the fixed reinforcement is located in the installation position, and the fixed reinforcement is connected to the cantilever bars in the installation position by welding or tying. At the same time, a support system (such as scaffolding support) is adopted at the bottom of the composite plate. After the composite plate in the entire frame constructed by the entire beam is hoisted and pressed, the plate surface reinforcement is tied on the surface of the composite plate so that the plate surface reinforcement can be connected to the fixed reinforcement and cantilever bars. After pouring the concrete covering layer, the installation of the composite plate and the construction of the plate surface can be completed. This allows the composite slab to be hung on the left and right sides of the beam by the reinforcement, avoiding the need for excessive scaffolding or other support systems to support the connection between the composite slab and the beam, helping to reduce the cost of scaffolding construction materials and other costs, improving construction efficiency, and ensuring that the subsequently installed composite slab can be connected to the beam as a whole, which helps to improve stability.

[0013] In order to ensure the stability of the crossbeam connection to the composite plate and ensure the overall strength of the crossbeam, it is preferred that the height from the bottom end of the barrier to the connection position is ≤ one half of the depth of the beam mold groove.

[0014] In order to facilitate the production of beam mold grooves and improve construction efficiency, it is preferred that the beam mold groove includes two side plates and a bottom plate, the bottom end of the side plate is connected to the upper surface of the bottom plate near the end to form a "U" shape, and the side plate is provided with a plurality of through holes near the top, and the through holes are radially perpendicular to the left to right direction of the side plate; the through holes are arranged along the length direction of the side plate; and the connection position is set corresponding to the through holes.

[0015] In order to facilitate the fixed installation of the barrier on the inner wall of the beam mold groove, improve stability and avoid displacement, preferably, the connecting position is provided with a connecting piece for installing the barrier on the inner wall of the beam mold groove; the connecting piece is a bolt, and the connecting position is provided with an internal threaded hole that can match the bolt; the bolt can pass through the through hole and be screwed into the internal threaded hole.

[0016] In order to prevent the connecting piece from falling off from the side plate, which would cause inconvenience in transportation and storage, preferably, the through hole is provided with an internal thread matching the bolt.

[0017] In order to improve construction efficiency and reduce raw material costs, it is preferred that a connecting piece for installing the barrier on the inner wall of the beam mold groove is provided on the connecting position; the connecting piece is a nail or a steel needle, and the nail or the steel needle can be inserted into the inner wall of the beam mold groove and inserted into the barrier from the connecting position.

[0018] In order to ensure that a suitable installation position structure can be formed on the beam after the beam is cast, to ensure the convenience of connecting and installing the composite plate and the beam, and to reduce the difficulty of connecting and installing the composite plate and the beam, it is preferred that the length of the barrier along the length direction of the side plate is at least 8 cm; the width of the barrier along the width direction from the left side to the right side of the side plate is less than the distance between the edge of the steel cage and the inner wall of the beam mold groove, and the width of the barrier along the width direction from the left side to the right side of the side plate is at least 2 cm.

[0019] In order to avoid the defect of exposed reinforcement in the steel cage due to the influence of the barrier after pouring concrete, it is preferred that the difference between the distance between the edge of the steel cage and the inner wall of the beam mold groove and the width of the barrier along the left to right width of the side plate is at least 0.5 cm.

[0020] Preferably, the steel cage includes a plurality of main bars and a plurality of annular bars, and the annular bars are tied with the main bars to form the steel cage; the pick bars are inserted in a direction perpendicular to the main bars.

[0021] More preferably, the pick ribs are arranged between adjacent ring ribs.

[0022] In order to enhance the strength of the steel cage, preferably, the steel cage is provided with a plurality of reinforcing ribs between adjacent ring bars and / or adjacent main bars.

[0023] Compared with the prior art, the technical effects created by the present invention are embodied in:

[0024] The overall structure of the beam cage formwork structure created by the present invention is simple, and the changes to the existing beam construction technology are relatively small. At the same time, it satisfies the need to form several mounting structures on the beam, making it convenient to use cantilever reinforcement to pick up the composite plate on the left and right sides of the beam, thereby ensuring the stability of the connection between the composite plate and the beam, and avoiding significantly improving the beam cage formwork structure while affecting the overall force-bearing capacity of the beam, thereby ensuring the overall weighing effect of the beam.

[0025] The invention has the advantages of simple construction process for the beam cage formwork and low construction cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] In order to facilitate those skilled in the art to correctly understand the present invention and enable them to fully understand the technical content of the present invention, the technical solution of the present invention is further elaborated below in conjunction with specific implementation methods, but this elaboration does not limit the scope of protection required for the present invention.

[0039] like Figure 1 and Figure 4 and Figure 5 and Figure 6 As shown, in certain embodiments, the present invention provides a method for constructing a beam cage formwork for connecting composite slab beams, comprising the following steps:

[0040] S1: Take a template for pouring concrete (for example: wood, iron, aluminum, plastic, etc.) and cut it into a side plate 4, open a plurality of through holes 9 near the top of the side plate 4, and the through holes 9 are radially perpendicular to the direction from the left to the right of the side plate 4, and the through holes 9 are arranged along the length direction of the side plate 4; take a template for pouring concrete (for example: wood, iron, aluminum, plastic, etc.) or a foam board and cut it into a barrier 6, the barrier 6 is provided with a connecting position 10 and a positioning hole 8, the connecting position 10 is arranged corresponding to the through hole 9, and the positioning hole 8 is opened on the side of the barrier 6, and the height from the bottom end of the barrier 6 to the connecting position 10 is ≤ half of the height from the top end to the bottom end of the side plate 4 (such as Figure 4 、 Figure 5 and Figure 6 Take a concrete pouring template (for example, a wooden board, an iron board, an aluminum board, a plastic board, etc.) and cut it into a bottom plate 5. Connect the bottom end of the side plate 4 to the upper surface of the bottom plate 5 near the end to form a beam mold groove (as shown in FIG. Figure 4 and installing the beam mold groove using scaffolding support;

[0041] S2: Take some main reinforcement 1 and ring reinforcement 2 for the concrete beam, and Figure 2、 Figure 3 and Figure 4 As shown, the main reinforcement 1 and the annular reinforcement 2 are tied together to form a steel cage; steel bars of the same material as the main reinforcement 1 or the annular reinforcement 2 or other steel bars are cut into pick bars 3, and the length of the pick bars 3 is greater than the width of the steel cage;

[0042] S3: Place the steel cage formed by binding in step S2 into the beam mold groove described in step S1, and insert a number of the pick bars 3 into the steel cage, and the pick bars 3 are inserted in a direction perpendicular to the main bars 1; place the blocking member 6 in the beam mold groove so that the end of the pick bar 3 is inserted into the positioning hole 8, and then align the connecting position 10 with the through hole 9, and use a connecting member 7 (such as a nail, etc.) to pass through the through hole 9 to connect the connecting position 10, so that the blocking member 6 is fixedly installed on the side plate 4, and the following is formed. Figure 4 As shown in the beam cage formwork structure. As for this embodiment, other matters not covered herein may be constructed by referring to the prior art or common knowledge known to those skilled in the art, and conventional technical means may be used, such as: forming the steel cage by binding, cutting the side panels 4, the bottom panel 5, and the barrier 6, and using scaffolding to support the beam formwork groove.

[0043] The invention is created by studying the construction method of the beam cage formwork. During the construction of the beam cage formwork, when the steel cage is placed into the beam mold groove, the pick reinforcement 3 is inserted, and the length of the pick reinforcement 3 is greater than the width of the steel cage, so that the left and right ends of the pick reinforcement 3 can extend from the steel cage; in the process of installing the combined beam mold groove, a barrier 6 is made and installed on the side plate 4, and a positioning hole 8 is set on the barrier 6. The end of the pick reinforcement 3 is inserted into the positioning hole 8 so that the pick reinforcement 3 is fixed. At the same time, the barrier 6 is installed on the side of the side plate 4 so that a number of protrusions can be formed on the side plate 4 into the beam mold groove, so that after the beam is cast, a mounting position 15 (such as Figure 7 and Figure 8 and Figure 9 and Figure 10 The construction method is simple, the construction process is simple, easy to operate and the cost is low. The materials of the main reinforcement 1, the ring reinforcement 2 and the cantilever reinforcement 3 used in the above embodiment can be selected by those skilled in the art according to the needs during the beam construction process.

[0044] In certain embodiments of the present invention, after the installation of the beam cage formwork is completed according to the above-mentioned beam cage formwork construction method, the construction of the beam that is convenient for the connection and installation of the composite plate can be completed by pouring concrete, so that a number of installation positions 15 that are convenient for the installation of the composite plate can be formed on the poured beam, which helps to reduce the difficulty of the installation construction of the composite plate and ensure the stability of the connection between the composite plate and the beam.

[0045] like Figure 4 As shown, in some embodiments, the connecting member 7 is a bolt, and the connecting portion 10 is provided with an internally threaded hole that mates with the bolt. The bolt is screwed into the connecting portion 10, mating with the internal threads in the internally threaded hole, thereby securing the barrier 6 to the side panel 4. This improves installation convenience and ensures stability. In some embodiments, if the barrier 6 is made of foam, a nail, steel needle, or the like may be more suitable as the connecting member 7. The needle or nail is inserted through the through-hole 9 into the connecting portion 10 to complete the connection. In some embodiments, the through-hole 9 is provided with internal threads that mate with the bolt. This allows the bolt, serving as the connecting member 7, to be screwed into the through-hole 9, threadedly connected, and then screwed into the internally threaded hole in the connecting portion 10, enhancing the stability of the connection between the barrier 6 and the side panel 4. Furthermore, this allows the bolt, serving as the connecting member 7, to remain intact with the side panel 4 during storage, preventing loss and the need for replacement during construction. This helps improve construction progress and reduce material costs.

[0046] like Figure 4 and Figure 6 As shown, in some embodiments, the bottom of the side plate 4 (such as Figure 4 、 Figure 5 and Figure 6 As shown, located at the bottom of the figure) is provided with a plurality of fixing holes 11, and the fixing holes 11 are arranged along the length direction of the side plate 4, and the axial direction of the fixing holes 11 is along the height direction of the side plate 4 (as shown Figure 4 、 Figure 5 and Figure 6As shown, in the direction from the lower end to the upper end); the bottom plate 5 is provided with a plurality of fixing positions that can match the fixing holes 11, and the fixing positions are connected to the fixing holes 11 through connectors 7, so that the bottom plate 5 and the side plate 4 are connected as a whole. This embodiment belongs to the connection method commonly used by those skilled in the art during the construction and installation of the beam mold groove, but the present invention has made the following improvements to this: by setting a plurality of fixing holes 11 at the bottom of the side plate 4, the side plate 4 and the bottom plate 5 are connected to the fixing positions through the fixing holes 11 through connectors 7, which helps to reduce the difficulty of construction and improve convenience, and ensure the accuracy of installation. In some embodiments, the connector 7 is a bolt, and the fixing position is a through-hole that passes through the upper and lower surfaces of the bottom plate 5. The fixing hole 11 is provided with an internal thread that matches the bolt. The bolt passes through the through-hole and is screwed into the internal thread to realize the connection between the side plate 4 and the bottom plate 5, thereby improving the convenience of installation and construction and helping to improve construction efficiency. In certain other embodiments, the through-holes are provided with internal threads matching the bolts, which facilitate the integral storage of the bolts with the base plate 5, avoiding the defect of losing parts and requiring replacement during construction, and also improving the stability of the connection between the base plate 5 and the side plates 4. In this embodiment, after the base plate 5 and the side plates 4 are combined to form the beam form, the use of scaffolding to support the beam form during construction is common knowledge and conventional technical means well known to those skilled in the art. Therefore, the construction can be carried out in accordance with existing scaffolding support beam form technology or common knowledge and conventional technical means.

[0047] like Figure 4 and Figure 5 and Figure 6 As shown, in some embodiments, the length of the barrier 6 along the length direction of the side plate 4 is at least 8 cm. After the construction of the beam cage form is completed, a protrusion at least 8 cm long along the length direction of the side plate 4 is formed in the beam form groove, so that when pouring concrete, the Figure 7-10 After the crossbeam 14 shown, a mounting position 15 of at least 8 cm long is formed along the length of the side plate 4 to ensure that the composite plate and the beam are connected and installed conveniently, and to ensure that after the beam and the composite plate are installed, they can form a bite assembly along the length of the side plate 4 after the concrete is poured, thereby improving stability. Figure 4 and Figure 5 and Figure 6 As shown, in some embodiments, the width of the barrier 6 along the width direction of the side plate 4 (from left to right) is at least 2 cm, and the width of the barrier 6 along the width direction of the side plate 4 (from left to right) is less than the distance between the edge of the steel cage and the inner wall of the beam mold groove; this can avoid the formation of the following when pouring concrete: Figure 7-10When the crossbeam 14 is constructed as shown, the main reinforcement 1 or the ring reinforcement 2 in the reinforcement cage is exposed, which affects the load-bearing performance of the crossbeam 14. Specifically, in some embodiments, the absolute value of the difference between the width of the barrier 6 along the width direction of the side plate 4 (from left to right) and the distance between the edge of the reinforcement cage and the inner wall of the beam groove is at least 0.5 cm, so that after the concrete is poured, it can be Figure 7-10 The installation position 15 shown is wrapped with a steel cage to prevent the steel cage from exposing the steel bars.

[0048] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown, in some embodiments, the length of the pick reinforcement 3 inserted into the positioning hole 8 is equal to the depth of the positioning hole 8 along the width direction of the barrier 6, so that the pick reinforcement 3 can be tightly fixed by the barrier 6 to avoid displacement during the concrete pouring process.

[0049] like Figure 4 As shown, in some embodiments, the positioning hole 8 is through-hole along the width direction of the barrier 6, that is, the positioning hole 8 passes through the left side to the right side of the barrier 6; this enables the rib 3 to be set to a longer length, ensuring that when the composite board is subsequently installed, the rib 3 is used to connect and install with the composite board, thereby improving the installation stability.

[0050] like Figure 2 and Figure 3 As shown, in some embodiments, the pick ribs 3 are arranged in a direction perpendicular to the main ribs 1 , and the pick ribs 3 are arranged in a horizontal direction.

[0051] like Figure 2 and Figure 3 As shown, in some embodiments, the pick bars 3 are arranged between adjacent ring bars 2, and several reinforcing bars are also provided between adjacent ring bars 2. This helps to improve the overall stability of the steel cage and ensure strength. In some embodiments, several reinforcing bars are provided between adjacent main bars 1 to improve the overall strength and stability of the steel cage.

[0052] like Figure 2 and Figure 3 As shown, in some embodiments, at least two of the cantilever bars 3 are arranged adjacent to the ring bars 2. This facilitates the subsequent installation of the composite slab, allowing the steel bars to be drawn out from the composite slab and connected as a whole, thereby reducing the difficulty of connecting the composite slab to the beam, improving the convenience and stability of the construction of the connection between the composite slab and the beam, and reducing the difficulty of construction.

[0053] like Figure 5As shown, in some embodiments, the spacing between two adjacent barrier members 6 installed on the side plate 4 is 15-40 cm. Figure 7-10 After the beam 14 is shown, the distance between adjacent installation positions 15 on the beam 14 is at an appropriate distance, ensuring the stability of the installation of the composite plate and the beam and improving the formation of the appropriate density of the bite components at the installation position 15 after the concrete is poured, thereby improving the stability of the connection between the composite plate and the beam.

[0054] The researchers who created this invention conducted a project study on the connection structure between the composite plates and the beams, and achieved improvements in the stability and convenience of the connection between the composite plates and the beams, thereby reducing the construction difficulty and cost of the connection between the composite plates and the beams.

[0055] The invention was created during the research process, taking into account the particularity of the beam-column structure, that is: Figure 7-10 As shown, the beam-column structure is usually formed by concrete columns 13 and crossbeams 14 erected on the concrete columns 13, so that the building body is a frame structure. In order to be able to continuously increase the height upward, column reinforcement cages 12 are provided in the concrete columns 13. The column reinforcement cages 12 are continuously connected and extended upward to achieve the purpose of raising the concrete columns 13 and then building a high-rise building. When the frame structure is built to the floor height, a crossbeam 14 structure needs to be constructed. Therefore, the reinforcement cages in the crossbeams 14 need to be cross-installed with the column reinforcement cages 12, and then concrete is poured to form a structure as shown in FIG. Figure 7-10 The beam-column structure shown. The composite slab is usually installed in a frame surrounded by beams 14. Therefore, the connection between the beams 14 and the composite slab 17 will be a technical problem that those skilled in the art need to overcome. When the traditional composite slab 17 is installed, a truss 18 is set up, and the truss 18 is fixedly connected to the steel structure in the top concrete layer that needs to be cast in place, while the composite slab 17 and the beams 14 are only attached to each other, resulting in the need to set up a large amount of scaffolding at the bottom to support the composite slab 17. Therefore, based on the perspective of this technical defect, the research members of this research team proposed the consideration of the connection structure between the composite slab 17 and the beams 14, and then formed the construction technical solution and several compatible structural technical solutions created by the present invention. Compared with the existing technology, the improvements in the structural technical solution specifically include:

[0056] like Figure 2 and Figure 3As shown, the reinforcement cage used to connect the composite slab beams includes: main bars 1 and ring bars 2, with the ring bars 2 used to bind and secure the main bars 1 into a single unit. The reinforcement cage is inserted with pick bars 3, inserted perpendicularly to the main bars 1 and arranged horizontally. This structure allows for the composite slab to be spliced on both sides of the beam after concrete is poured to form the beam, facilitating the subsequent connection and installation of the composite slab and beam.

[0057] like Figure 4 As shown, in some embodiments, a beam cage mold structure is used for casting beams that are convenient for connecting composite plates, including a beam mold groove and a steel cage, the steel cage is placed in the beam mold groove, and a number of pick bars 3 are inserted into the steel cage; a number of blocking members 6 are provided on the inner wall of the beam mold groove, and a number of protrusions are formed in the beam mold groove after the blocking members 6 are installed on the inner wall of the beam mold groove; a positioning hole 8 and a connecting position 10 are provided on the blocking member 6, and the connecting position 10 is used to install the blocking member 6 on the inner wall of the beam mold groove; after the blocking member 6 is installed on the inner wall of the beam mold groove, the two ends of the pick bars 3 can be inserted into the positioning hole 8; the height from the bottom end of the blocking member 6 to the connecting position 10 is ≤ one half of the depth of the beam mold groove.

[0058] like Figure 4 As shown, in some embodiments, the beam mold groove includes two side plates 4 and a bottom plate 5, the bottom end of the side plate 4 is connected to the upper surface of the bottom plate 5 near the end to form a "U" shape, and the side plate 4 is provided with a plurality of through holes 9 near the top, and the through holes 9 are radially perpendicular to the left to right direction of the side plate 4; the through holes 9 are arranged along the length direction of the side plate 4; the connection position 10 is arranged corresponding to the through holes 9.

[0059] like Figure 4 As shown, in some embodiments, the connecting position 10 is provided with a connecting member 7 for installing the barrier 6 on the inner wall of the beam mold groove; the connecting member 7 is a bolt, and the connecting position 10 is provided with an internal threaded hole that can match the bolt; the bolt can pass through the through hole 9 and be screwed into the internal threaded hole.

[0060] like Figure 4 As shown, in some embodiments, a connecting member 7 for installing the blocking member 6 on the inner wall of the beam mold groove is provided on the connecting position 10; the connecting member 7 is a nail or a steel needle, and the nail or the steel needle can be inserted into the inner wall of the beam mold groove and inserted into the blocking member 6 from the connecting position 10.

[0061] like Figure 2-3As shown in 7-10, the crossbeam connecting the composite slab includes a concrete layer and a steel cage, the steel cage is located in the concrete layer, and a number of cantilever bars 3 are inserted into the steel cage, the concrete layer is provided with a number of mounting positions 15 at the top, and the cantilever bars 3 are inserted from the mounting positions 15; specifically, the crossbeam structure is a crossbeam structure formed after pouring concrete through the above-mentioned beam cage mold structure.

[0062] When the crossbeam structure is used to install the composite plate, a composite plate structure that matches it can be used, such as Figure 7-10 The structure of the composite plate 17 shown. The composite plate structure commonly used in the prior art can also be adopted. A hole corresponding to the installation position 15 is opened on the edge of the composite plate, and a steel bar is inserted into the hole as an extension bar 16. The depth of the hole can allow the extension bar 16 to be inserted into the composite plate by at least 5 cm. The hole is filled with post-cast concrete so that the extension bar 16 is fixed to the edge of the composite plate. The extension bar 16 is then aligned with the installation position 15 and inserted into the installation position 15. The extension bar 16 is fixedly connected to the pick bar 3, and the truss 18 at the top of the composite plate is fixedly connected to the steel structure in the post-cast concrete layer. Then, post-cast concrete is poured to make the connection between the composite plate and the beam 14 more stable. At the same time, during the process of hoisting the composite plate, the connection between the pick bar 3 and the extension bar can be used to connect the composite plate and the beam 14 together, which helps to reduce the support force required for the bottom scaffolding support and ensure construction safety. It also ensures the integrity of the connection between the composite plate and the beam.

[0063] In addition, in order to not change the existing beam structure, the researchers of the present invention have designed a composite plate structure that is convenient for connection to the beam by drilling holes and installing reinforcement bars on the beam structure to connect the composite plate and the beam into a whole, and to achieve the interlocking connection of the composite plate, the post-cast concrete layer and the beam by post-casting concrete layer. Figure 7-10, including a concrete layer and a matching position 22 set along the edge of the concrete layer, a plate steel bar is provided in the concrete layer, and a fixing bar 19 is provided on the matching position 22, one end of the fixing bar 19 is connected to the plate steel bar, and a truss 18 is provided on the top of the concrete layer, and the truss 18 is connected to the plate steel bar. When in use, first, holes are drilled on both sides of the beam to install the pick bars corresponding to the matching position 22, and then the composite board in this embodiment is hoisted to a certain position using a crane so that the pick bars are installed corresponding to the matching position 22, the pick bars are fixedly connected to the fixing bar 19, and then the truss 18 is connected and fixed to the steel structure in the post-cast concrete layer, and then the concrete is poured. The connection and installation of the composite board and the crossbeam are completed, ensuring the stability of the connection between the composite board and the crossbeam. At the same time, it can reduce the support force required for the scaffolding support at the bottom of the composite board during construction, ensuring construction safety. Specifically, the scaffolding construction and support during the installation process belong to conventional technical means and common knowledge of those skilled in the art. Those skilled in the art can implement them according to the existing technology or the common knowledge mastered by those skilled in the art and conventional technical means.

[0064] In addition, the above-mentioned composite plate structure can also be installed in conjunction with the beam structure obtained in the invention. During installation, it is only necessary to install the matching position 22 and the installation position 15 correspondingly, so that the fixed reinforcement 19 and the cantilever reinforcement 3 are connected into a whole, and then the concrete is poured to complete the installation of the beam and the composite plate.

[0065] In some embodiments, when the connection length between the fixing rib 19 and the pick rib 3 is insufficient, an extension rib 16 can be fixedly connected to the fixing rib 19 or the pick rib 3 so that the fixing rib 19 and the pick rib 3 are integrally connected. The fixed connection in this embodiment can be achieved by welding or binding.

[0066] In some embodiments, in order to facilitate construction, a fixing piece 20 is provided on the fixing rib 19 to facilitate the fixed connection between the fixing rib 19 and the pick rib 3, thereby improving construction convenience.

[0067] In some embodiments, a chamfer 21 is provided on the top edge of the matching position 22, which reduces the weight of the overall structure of the composite slab and helps to make the top of the matching position 22 fit tightly against the surface of the post-cast concrete layer.

[0068] Other matters not covered by the present invention may be achieved by conventional technical means with reference to the prior art or common knowledge known to those skilled in the art, for example, the construction of scaffolding during the construction process.
