[0001] This utility model relates to the field of building engineering, and in particular to a mold for assembling precast concrete building components. Background Technology

[0002] In the field of construction engineering, the application of precast concrete building components is becoming increasingly widespread. These components, after being prefabricated in the factory, need to be transported to the construction site for assembly. However, traditional assembly methods often suffer from problems such as loose joints and unstable assembly quality, which not only affect the overall structural performance of the building but may also pose a potential threat to its safety. To address these issues, this invention proposes a mold for assembling precast concrete building components. Utility Model Content

[0003] The purpose of this utility model is to provide a mold for assembling precast concrete building components to solve the above-mentioned technical problems. To achieve the above purpose, this utility model adopts the following technical solution: A mold for splicing precast concrete building components includes an outer fixing plate for splicing joints and inner filling fixing components for splicing joints. The outer fixing plates for splicing joints are arranged opposite each other, and several groups of inner filling fixing components for splicing joints are arranged between the opposite outer fixing plates for splicing joints, with both ends of the inner filling fixing components for splicing joints fixed to the outer fixing plates for splicing joints.

[0004] Based on the above technical solution, the outer fixing plate of the splice seam is provided with several sets of single-sided protrusions, and the center of the several sets of single-sided protrusions is provided with a fixing member through hole. The two ends of the fixing member filled in the splice seam are inserted into the fixing member through hole in the center of the single-sided protrusion.

[0005] Based on the above technical solution, the splice seam filling fixing component consists of transverse steel bars, longitudinal steel bars, steel bar sleeves, and side-end fixing caps. The longitudinal steel bars are welded and fixed to both sides of the steel bar sleeves in opposite directions. Multiple sets of steel bar sleeves and longitudinal steel bars are provided. Multiple sets of steel bar sleeves are correspondingly fitted onto the transverse steel bars in the seam, and the multiple sets of longitudinal steel bars are arranged on both sides of the transverse steel bars in the seam. The side-end fixing caps are connected to both ends of the transverse steel bars in the seam in opposite directions. The side ends of the transverse steel bars in the seam pass through the through holes of the single-sided protrusion center fixing component, and the outer ends of the side-end fixing caps are located outside the through holes of the single-sided protrusion center fixing component.

[0006] Based on the above technical solution, the two ends of the transverse steel bar in the gap are provided with connecting threads. The side end fixing cap is composed of a fixing cap tube, an outwardly protruding limiting ring, and a side end screwing ear. The side end screwing ears are arranged oppositely on the outer end of the fixing cap tube. The outwardly protruding limiting ring is arranged on the outer side of the fixing cap tube near the side end screwing ear. The fixing cap tube is provided with internal threads. The internal threads of the fixing cap tube correspond to the connecting threads of the side end of the transverse steel bar in the gap. The fixing cap tube is inserted into the through hole of the fixing component, and the outwardly protruding limiting ring is tightly attached to the outer side of the through hole of the fixing component.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0015] A mold for splicing precast concrete building components includes an outer fixing plate 1 for splicing joints and an inner filling fixing member 2 for splicing joints. The outer fixing plates 1 are arranged opposite each other, and several groups of inner filling fixing members 2 are arranged between the outer fixing plates 1 on opposite sides, with both ends of the inner filling fixing members 2 fixed to the outer fixing plates 1.

[0016] The above are the two main components of the overall structure, corresponding to the appendix. Figure 1 and attached Figure 2 .

[0017] The splice seam outer fixing plate 1 is provided with several sets of single-sided protrusions 3, and the center of the several sets of single-sided protrusions 3 is provided with a fixing member through hole 4. The two ends of the splice seam filling fixing member 2 are inserted into the fixing member through hole 4 in the center of the single-sided protrusion 3.

[0018] The above details the specific features of the outer fixing plate 1 for the splicing seam, and are attached accordingly. Figure 3 .

[0019] The splice seam filling fastener 2 consists of transverse steel bars 5, longitudinal steel bars 6, steel bar sleeves 7, and side-end fixing caps 8. The longitudinal steel bars 6 are welded and fixed to both sides of the steel bar sleeves 7 in opposite directions. Multiple sets of steel bar sleeves 7 and longitudinal steel bars 6 are provided. Multiple sets of steel bar sleeves 7 are correspondingly fitted onto the transverse steel bars 5 in the gap, and the multiple sets of longitudinal steel bars 6 are arranged on both sides of the transverse steel bars 5 in the gap. The side-end fixing caps 8 are connected to both ends of the transverse steel bars 5 in opposite directions. The side ends of the transverse steel bars 5 in the gap pass through the through hole 4 of the central fastener of the single-sided protrusion 3, and the outer ends of the side-end fixing caps 8 are located outside the through hole 4 of the central fastener of the single-sided protrusion 3.

[0020] The above describes the specific components, connection relationships, and positional relationships of the splice seam filling fastener 2. (See attached diagram.) Figure 4 .

[0021] The transverse steel bar 5 in the gap has connecting threads 9 at both ends. The side-end fixing cap 8 is composed of a fixing cap tube 10, an outwardly protruding limiting ring 11, and a side-end screwing ear 12. The side-end screwing ear 12 is set opposite to the outer end of the fixing cap tube 10. The outwardly protruding limiting ring 11 is set on the outer side of the fixing cap tube 10 near the side-end screwing ear 12. The fixing cap tube 10 has an internal thread 13. The internal thread 13 of the fixing cap tube 10 is connected to the connecting thread 9 at the side end of the transverse steel bar 5 in the gap. The fixing cap tube 10 is inserted into the fixing member through hole 4, and the outwardly protruding limiting ring 11 is tightly attached to the outer side of the fixing member through hole 4.

[0022] The above describes the connection relationship between the side ends of the transverse reinforcing bars 5 and the side end fixing caps 8 within the gap, corresponding to the attached diagram. Figure 5 .

[0023] In practical application, firstly, construction personnel need to place the outer fixing plate 1 of the splice joint opposite each other on both sides of the splice joint of the precast concrete building component, ensuring that the position of the single-sided protrusion 3 is accurately aligned, so as to facilitate the subsequent installation of the splice joint filling fixing component 2. Next, the transverse steel bars 5 in the gap are passed through the corresponding multiple sets of steel bar sleeves 7. The longitudinal steel bars 6 in the gap have been pre-welded to both sides of these steel bar sleeves 7, forming a stable filling concrete skeleton structure. During the installation process, attention should be paid to the arrangement order of the multiple sets of steel bar sleeves 7 and the longitudinal steel bars 6 in the gap on the transverse steel bars 5 in the gap, to ensure the balance and stability of the overall structure. Subsequently, the two ends of the installed splice joint filling fixing component 2 are aligned with the fixing hole 4 in the center of the single-sided protrusion 3 on the outer fixing plate 1 of the splice joint, and slowly pushed in until the outer end of the side fixing cap 8 is exposed outside the fixing hole 4. At this point, the construction workers can rotate the side-end fixing cap 8 by twisting the side-end ear 12, and use the internal thread 13 inside the fixing cap tube 10 to connect tightly with the connecting thread 9 on the side end of the transverse steel bar 5 in the gap, until the outwardly protruding limiting ring 11 is tightly attached to the outside of the fixing member through hole 4, thus completing the fixing of the filling fixing member 2 in the splice seam.

[0024] After the concrete is poured and solidified, the splice joint outer fixing plate 1 needs to be removed. At the same time, it is only necessary to remove the side fixing cap 8 from the connecting thread 9 on the side end of the transverse steel bar 5 in the gap, pry loose the splice joint outer fixing plate 1 and remove the splice joint outer fixing plate 1, so that the splice joint outer fixing plate 1 and the side fixing cap 8 can be recycled.

[0025] The entire installation process must ensure that all components are tightly connected without any looseness, guaranteeing a dense filling and stable fixation of the joints. This structural design not only improves the splicing quality of precast concrete building components and the structural performance of the building, but also enables the reusability of external formwork, effectively reducing construction costs.

[0026] The above description is a preferred embodiment of the present utility model. For those skilled in the art, any changes, modifications, substitutions and variations made to the implementation methods without departing from the principles and spirit of the present utility model, based on the teachings of the present utility model, still fall within the protection scope of the present utility model.
