Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, and specifically, to an assembled precast composite beam shell. Background Art
[0002] An assembled precast composite beam shell is a precast composite beam structure manufactured by using an assembled construction technology. The main feature of this structure is that precast components are fabricated in a factory and then transported to the construction site for assembly. The assembled construction technology can significantly improve the construction efficiency and quality of building projects and reduce the time required for on-site construction.
[0003] During use, a steel reinforcement cage needs to be placed into the beam shell and fixed by fasteners. However, after the user places the steel reinforcement cage into the beam shell, some steel bars will block the connection of the fasteners, resulting in the inability to fix the fasteners. The absence of fasteners at some positions will cause uneven stress on the inner wall of the beam shell after pouring concrete, resulting in deformation of the beam shell. Summary of the Utility Model
[0004] The utility model provides an assembled precast composite beam shell. In this solution, multiple sliders can be adjusted in position, thus avoiding the situation where the installation of the fastening components is impossible due to the sliders being blocked by the steel reinforcement cage, ensuring that the fastening components can be installed in each through hole, thereby ensuring uniform stress on the inner wall of the beam shell, effectively reducing the possibility of deformation of the beam shell, and improving the practicality of the device.
[0005] For this purpose, the following technical solutions are adopted:
[0006] An assembled precast composite beam shell includes a beam shell and a steel reinforcement cage. The beam shell is of a U-shaped structure and includes two parallel mounting plates. A number of equally spaced limiting holes are formed along the length direction of the two mounting plates. The limiting holes are strip-shaped holes, and the limiting holes on the two mounting plates correspond one by one. Between the two mounting plates, a plurality of U-shaped connectors corresponding to the limiting holes are provided. The two ends of the U-shaped connector respectively pass through the limiting holes on both sides and symmetrically fix sliders. Through holes are formed in the sliders. A plurality of fastening components are arranged inside the beam shell. The fastening component includes a screw rod and a pair of nuts. The two ends of the screw rod respectively pass through the through holes on two symmetric sliders and are locked by nuts.
[0007] A further technical solution lies in that: the outer shape of the U-shaped connector matches the shape of the inner cavity of the beam shell and is close to each other.
[0008] A further technical solution lies in that: a pair of symmetric reinforcing plates are fixed at the bending part of the U-shaped connector, and the reinforcing plates are inclined.
[0009] A further technical solution lies in that: A set of symmetrically arranged support bars are fixed at the bottom of the inner wall of the beam shell. The support bars are arranged along the length direction of the beam shell and are provided with a plurality of movable slots.
[0010] A further technical solution lies in that: The movable slots are arranged at equal intervals, and their positions and lengths correspond one by one to the limiting holes.
[0011] A further technical solution lies in that: The U-shaped connecting piece passes through the movable slots.
[0012] A further technical solution lies in that: The height of the upper surface of the support bar is higher than the highest point of the reinforcing plate.
[0013] The working principle and beneficial effects of this application are as follows:
[0014] 1. In this solution, the positions of multiple sliders can be adjusted, thus avoiding the situation where the installation of the fastening components is impossible due to the sliders being blocked by the steel reinforcement cage. This ensures that the fastening components can be installed in each through hole, thereby ensuring uniform stress on the inner wall of the beam shell, effectively reducing the possibility of deformation of the beam shell, and improving the practicality of the device.
[0015] 2. In this solution, a reinforcing plate is integrally formed at the inner end of the U-shaped connecting piece. The setting of the reinforcing plate effectively enhances the stability and rigidity of the U-shaped connecting piece, enabling the U-shaped connecting piece itself to apply an inward pulling force to both ends of the beam shell, further enhancing the stability of the beam shell structure.
[0016] 3. In this solution, support bars are provided at the bottom end of the inner wall of the beam shell. The setting of the support bars can prevent the steel reinforcement cage from obstructing the movement of the U-shaped connecting piece and the sliders. At the same time, it can cause a part of the gap to be left between the steel reinforcement cage and the bottom end of the inner wall of the beam shell. The reserved gap can ensure that the concrete fully fills the space around the steel reinforcement cage, helping to avoid the voids and pores that occur during concrete pouring and improving the overall quality of concrete pouring.

[0023] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.
[0024] As Figures 1 - 3 shown, a prefabricated assembled composite beam shell includes a beam shell 1 and a steel reinforcement cage 2. The beam shell 1 is of a U-shaped structure and includes two parallel mounting plates 11. A number of equally spaced limit holes 3 are provided on the two mounting plates 11 along their length directions. The limit holes 3 are strip-shaped holes, and the limit holes 3 on the two mounting plates 11 correspond to each other one by one.
[0025] Among them, a plurality of U-shaped connecting pieces 5 corresponding to the limit holes are arranged between the two mounting plates 11. The two ends of the U-shaped connecting piece 5 respectively pass through the limit holes 3 on both sides and symmetrically fix slide blocks 6. Through holes 7 are provided on the slide blocks 6. A plurality of fastening assemblies 4 are arranged inside the beam shell 1. The fastening assembly 4 includes a screw rod 401 and a pair of nuts 402. The two ends of the screw rod 401 respectively pass through the through holes 7 on two symmetric slide blocks 6 and are locked by nuts 402. And the outer shape of the U-shaped connecting piece 5 matches the shape of the inner cavity of the beam shell 1 and is close to each other.
[0026] The prefabricated assembled composite beam shell is a prefabricated composite beam structure manufactured by using prefabricated construction technology. The main feature of this structure is to prefabricate components in the factory and then transport the components to the site for assembly. The prefabricated construction technology can greatly improve the construction efficiency and quality of construction projects and reduce the time required for on-site construction.
[0027] In this solution, the U-shaped connector 5 can slide in the limiting holes 3 through a pair of sliders 6. After the user places the steel reinforcement cage 2 inside the beam shell 1, if the stirrups on the steel reinforcement cage 2 block the through holes 7 on the sliders 6, the user can pull the sliders 6 to slide in the limiting holes 3, thereby driving the U-shaped connector 5 and the pair of sliders 6 to change positions, so that the through holes 7 are separated from the stirrups. Then, the user can smoothly penetrate the screw rod 401 through the pair of through holes 7 and sleeved the nuts 402 on the outer ends of the screw rod 401, so that the mutually approaching ends of the pair of nuts 402 are tightly abutted against the outer wall of the beam shell 1, thereby enabling the screw rod 401 to form an inward pulling force on the side walls at both ends of the beam shell 1. When the user pours concrete into the beam shell 1, the action of the multiple fastening components 4 can prevent the beam shell 1 from deforming outward. The multiple sliders 6 can all be adjusted in position to ensure that the fastening components 4 can be installed in each through hole 7, thereby ensuring that the inner wall of the beam shell 1 is uniformly stressed and further reducing the possibility of the beam shell 1 deforming.
[0028] In this solution, the structure that applies an inward pulling force to both ends of the beam shell 1 is not limited to the fastening components 4, and other tie members can also be used, such as end clamping members, that is, both ends are clamped on the beam shell 1, or in a non-removable form, that is, both ends are fixed on the beam shell 1. The advantage of the removable form is that the user can first place the steel reinforcement cage 2 and then install the fasteners. During the process, the fasteners can be disassembled, so that the user can replace the steel reinforcement cage 2 or flexibly adjust the position of the steel reinforcement cage 2. Moreover, the beam shell 1 and the steel reinforcement cage 2 can be transported separately during transportation. If fixed fasteners at both ends are used, the fixing work of the fasteners needs to be carried out after placing the steel reinforcement cage 2, such as welding at both ends of the fasteners. After welding, the steel reinforcement cage 2 cannot be taken out anymore. If there are problems with the structure of the steel reinforcement cage 2, it is difficult for the user to replace it, and the beam shell 1 and the steel reinforcement cage 2 cannot be separated during transportation, which may cause inconvenience to the transportation process.
[0029] As Figure 3 shown, a pair of symmetrically arranged reinforcing plates 10 are fixed at the bending part of the U-shaped connector 5, and the reinforcing plates 10 are inclined.
[0030] The function of setting the reinforcing plates 10 is to enhance the stability and stiffness of the U-shaped connector 5, form a triangular support system in the structure, and effectively resist the forces in the horizontal and vertical directions, so that the U-shaped connector 5 itself can apply an inward pulling force to both ends of the beam shell 1, further enhancing the stability of the beam shell 1 structure.
[0031] As Figure 2 and Figure 4As shown, a set of symmetrically arranged support bars 8 are fixed to the bottom of the inner wall of the beam shell 1. The support bars 8 are arranged along the length direction of the beam shell 1 and are provided with a plurality of movable slots 9. The movable slots 9 are arranged at equal intervals, and their positions and lengths correspond one by one to the limiting holes 3. The U-shaped connecting piece 5 is arranged through the movable slots 9. The height of the upper surface of the support bar 8 is higher than the highest point of the reinforcing plate 10.
[0032] At the bottom end of the inner wall of the beam shell 1, a pair of symmetrically arranged support bars 8 are fixedly connected. A plurality of movable slots 9 are provided at the bottom end of the support bars 8. The plurality of movable slots 9 are arranged at equal intervals, and the positions of the plurality of movable slots 9 correspond one by one to the positions of the plurality of limiting holes 3. The U-shaped connecting piece 5 penetrates through the movable slots 9. The length of the movable slots 9 is set to be the same as the length of the limiting holes 3. The height of the upper surface of the support bar 8 is set to be higher than the highest point of the reinforcing plate 10.
[0033] When the user moves the U-shaped connecting piece 5, the bottom end of the U-shaped connecting piece 5 can move inside the movable slot 9. Therefore, the setting of the support bar 8 will not affect the movement of the U-shaped connecting piece 5 and the slider 6. When the user places the steel cage 2 inside the beam shell 1, the bottom end of the steel cage 2 abuts against the top ends of the pair of support bars 8, so that the steel cage 2 does not contact the U-shaped connecting piece 5 and the reinforcing plate 10, avoiding the influence of the steel cage 2 on the movement of the U-shaped connecting piece 5. At the same time, the setting of the support bar 8 leaves a gap between the steel cage 2 and the bottom end of the inner wall of the beam shell 1. The reserved gap can ensure that the concrete fully fills the space around the steel cage 2, helping to avoid the voids and pores that occur during concrete pouring and improving the overall quality of concrete pouring.
[0034] Working principle:
[0035] During use, the user places the steel cage 2 inside the beam shell 1, making the bottom end of the steel cage 2 abut against the top ends of the support bars 8. Then, fastening components 4 are installed on each pair of sliders 6. The specific process is as follows: The screw rod 401 is passed through a pair of through holes 7, and a pair of nuts 402 are respectively sleeved on the two ends of the screw rod 401, making the mutually approaching ends of the pair of nuts 402 tightly abut against the outer wall of the beam shell 1, so that the screw rod 401 forms an inward pulling force on the side walls at both ends of the beam shell 1. When the user pours concrete into the beam shell 1, the action of the plurality of fastening components 4 can prevent the beam shell 1 from deforming outward. If the stirrups on the steel cage 2 block the through holes 7 on the sliders 6, the user can pull the sliders 6 to slide in the limiting holes 3, thereby driving the U-shaped connecting piece 5 and the pair of sliders 6 to change positions, so that the through holes 7 are separated from the stirrups. Each of the plurality of sliders 6 can be adjusted in position, ensuring that the fastening components 4 can be installed in each through hole 7 and ensuring uniform force on the inner wall of the beam shell 1.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
