Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and more specifically, to prefabricated concrete pouring floor slabs. Background Technology

[0002] Prefabricated buildings have many advantages, such as shortening the construction period and saving manpower. Therefore, prefabricated buildings are being developed more and more vigorously. Prefabricated floor slabs are one type of prefabricated building.

[0003] Current prefabricated floor slab structures typically involve installing ribs and grooves on both sides of the floor slab, with connections made through the cooperation of the ribs and grooves. However, the strength of the connections in this structure is not high, affecting the overall strength of the floor slab.

[0004] A search revealed that Chinese patent CN222477897U discloses a prefabricated floor slab structure. Adjacent concrete floor slabs are connected and positioned by the extended ends of upper and lower reinforcing bars and positioning holes. Furthermore, a cast-in-place concrete filling gap is provided between adjacent concrete floor slabs. When pouring the upper layer of concrete, the upper layer of concrete enters the cast-in-place concrete filling gap, connecting groove, and positioning hole, fixing the adjacent concrete floor slabs into a whole, resulting in higher overall floor slab strength.

[0005] In actual use, the above-mentioned prefabricated floor slab structure is installed manually during the splicing of concrete floor slabs. This can easily lead to deviations in the position of the floor slabs during the splicing process, resulting in inaccurate and irregular splicing. Furthermore, it requires repeated adjustments to the position of the floor slabs, thereby reducing construction efficiency. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the present invention provides a prefabricated concrete pouring floor slab to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] The precast concrete floor slab includes two concrete floor slabs, with multiple steel bar placement positions provided on the upper surface of the two concrete floor slabs. The multiple steel bar placement positions are symmetrically distributed on the upper surface of the concrete floor slabs. A connecting component is installed between the two concrete floor slabs, and a reinforcing mechanism is installed inside the concrete floor slabs.

[0009] The connecting assembly includes a connecting plate disposed between two concrete floor slabs. Multiple insertion holes are symmetrically distributed on the upper surface of the connecting plate. Multiple insertion rods are fixedly connected to the top of the connecting plate. A first slot is formed on the inner side of each insertion rod. Two second slots are formed at both ends of each concrete floor slab. The insertion rods are inserted and fixedly connected to the inner sides of the second slots. Multiple insertion blocks are fixedly connected to both sides of each concrete floor slab. The insertion blocks are adapted to the inner sides of the insertion holes and are inserted into the inner sides of the insertion holes. Two extrusion blocks are fixedly connected to the inner side of each second slot. One side of the extrusion block is adapted to the outer side of the insertion rod. An insertion plate is fixedly connected to the inner side of each second slot and is inserted and fixedly connected to the inner side of the first slot.

[0010] By adopting the above technical solution, positioning can be provided for splicing two concrete floor slabs, so that the two concrete floor slabs can be installed quickly, thereby improving the installation and construction efficiency.

[0011] As a further description of the above technical solution: the reinforcing mechanism includes a reinforcing cavity, which is opened inside the concrete floor slab. A partition plate is fixedly connected inside the reinforcing cavity. Multiple reinforcing longitudinal beams and reinforcing transverse beams are installed on the top of the partition plate. Both ends of the reinforcing transverse beams and reinforcing longitudinal beams are fixedly connected to the inside of the reinforcing cavity. The reinforcing longitudinal beams and reinforcing transverse beams are evenly distributed inside the reinforcing cavity. Multiple spiral reinforcing ribs are provided below the partition plate and are fixedly connected to the inside of the reinforcing cavity.

[0012] By adopting the above technical solutions, the overall strength of the concrete floor slab can be increased, thereby improving the structural stability.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. By setting up connecting components, compared with existing technologies, the "concave" shaped connecting plate, together with multiple inserts and holes, can provide effective and accurate positioning for concrete floor slab installation, so as to quickly complete the splicing of two concrete floor slabs, reduce the time of repeated manual adjustments, help improve construction efficiency, and reduce the amount of concrete used by pouring concrete after splicing two concrete floor slabs, thereby increasing the construction speed.

[0015] 2. By setting up a reinforcement mechanism, compared with the existing technology, the use of multiple reinforcing longitudinal beams and reinforcing transverse beams distributed in a "well" shape, combined with spirally designed spiral reinforcing bars, can enhance the shear strength and torsional performance of concrete floor slabs. It can reduce the risk of local damage caused by insufficient unidirectional reinforcement and reduce the deflection deformation of concrete floor slabs under load, thereby improving structural stability.

[0023] The technical solutions of the present 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 the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] The embodiments disclosed in this application are as follows: Figure 1-6 The prefabricated concrete pouring floor slab shown includes two concrete floor slabs 1. Multiple steel bar placement positions 2 are provided on the upper surface of the two concrete floor slabs 1. The multiple steel bar placement positions 2 are symmetrically distributed with the upper surface of the concrete floor slabs 1. A connecting component is installed between the two concrete floor slabs 1. A reinforcing mechanism is installed inside the concrete floor slabs 1.

[0025] The connecting assembly includes a connecting plate 3, which is disposed between two concrete floor slabs 1. Multiple insertion holes 4 are formed on the upper surface of the connecting plate 3, symmetrically distributed. Multiple insertion rods 5 are fixedly connected to the top of the connecting plate 3, and a first slot 6 is formed on the inner side of each insertion rod 5. Two second slots 10 are formed at both ends of each concrete floor slab 1, and the insertion rods 5 are inserted into and fixed to the inner sides of the second slots 10. Multiple insertion blocks 9 are fixedly connected to both sides of each concrete floor slab 1, and the insertion blocks 9 are adapted to the inner sides of the insertion holes 4 and are inserted into the inner sides of the insertion holes 4. Two extrusion blocks 8 are fixedly connected to the inner side of the second slot 10. One side of the extrusion block 8 is adapted to the outer side of the insertion rod 5. An insertion plate 7 is fixedly connected to the inner side of the second slot 10. The insertion plate 7 is inserted and fixed to the inner side of the first slot 6. The "concave" design of the connecting plate 3 can provide a limit when connecting the concrete floor slab 1. It cooperates with the two insertion rods 5 and multiple insertion holes 4. The two insertion rods 5 can be inserted into the second slot 10, and the multiple insertion blocks 9 can be inserted into the inner side of the insertion holes 4. This can provide positioning for the installation of the concrete floor slab 1, thereby improving the installation accuracy, reducing the time of repeated manual adjustments and helping to improve construction efficiency. At the same time, after the two concrete floor slabs 1 are spliced, the steel bars can be installed through the steel bar placement position 2. After the steel bars are installed, the concrete can be poured, which can reduce the amount of concrete used.

[0026] Reference Figure 5 and 6 As shown, the reinforcing mechanism includes a reinforcing cavity 11, which is formed inside the concrete floor slab 1. A partition plate 12 is fixedly connected inside the reinforcing cavity 11. Multiple reinforcing longitudinal beams 13 and reinforcing transverse beams 14 are installed at the top of the partition plate 12. Both ends of the reinforcing transverse beams 14 and the reinforcing longitudinal beams 13 are fixedly connected to the inside of the reinforcing cavity 11. The reinforcing longitudinal beams 13 and the reinforcing transverse beams 14 are evenly distributed inside the reinforcing cavity 11. Multiple spiral reinforcing ribs 15 are arranged below the partition plate 12 and are fixedly connected to the inside of the reinforcing cavity 11. Through the cooperation of multiple staggered reinforcing longitudinal beams 13 and reinforcing transverse beams 14 and multiple spiral reinforcing ribs 15, the overall strength of the concrete floor slab 1 can be improved inside the concrete floor slab 1. This can reduce the risk of local damage caused by insufficient unidirectional reinforcement and reduce the deflection deformation of the concrete floor slab 1 under load, thereby improving structural stability.

[0027] Working principle of this utility model: This utility model designs a prefabricated concrete pouring floor slab, the specific structure of which is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation between various structures, when concrete pouring is required for the floor slab, firstly, the inner sides of the two second slots 10 on one side of one of the concrete floor slabs 1 are aligned with the two inserts 5 on the connecting plate 3, and multiple inserts 9 are aligned with the inner sides of the insertion holes 4. At the same time, the "concave" design of the connecting plate 3 can provide a limit for the installation of the concrete floor slab 1. Then, one of the concrete floor slabs 1 is placed on the connecting plate 3 from top to bottom, so that one of the concrete floor slabs 1 is connected to the connecting plate 3. When the two inserts 5 are inserted into the inner side of the second slots 10, the inserts 5 can drive the first slot 6 to be inserted into the outer side of the insert plate 7. This increases the tightness of the connection. At the same time, the two extrusion blocks 8 are adapted to the outside of the insertion rod 5, so that the two extrusion blocks 8 can be supported inside the second slot 10 and the contact area with the insertion rod 5 can be increased. After the concrete floor slab 1 is connected to the connecting plate 3, the concrete floor slab 1 and the connecting plate 3 are placed in a suitable position so that the other concrete floor slab 1 can be connected to the connecting plate 3, thus completing the splicing of the two concrete floor slabs 1. Then, the steel bars can be installed through the multiple steel bar placement positions 2 on the upper surface of the two concrete floor slabs 1. After the steel bars are installed, concrete is poured, thus reducing the amount of concrete used.

[0028] By using multiple staggered reinforcing longitudinal beams 13 and reinforcing transverse beams 14, stress points can be increased inside the concrete floor slab 1, and the internal strength of the concrete floor slab 1 can be increased, improving shear strength. In conjunction with multiple spirally designed spiral reinforcing ribs 15, the overall stability of the structure can be enhanced.

[0029] In the accompanying drawings of the embodiments disclosed in this utility model, only the structures involved in the embodiments of this utility model are shown. Other structures can be referred to with ordinary design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.

[0030] All contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used. Electrical control components not mentioned in this technical solution are existing technologies and are therefore not shown in the figures and will not be described here.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
