Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building engineering, and in particular to a hollow slab beam foam core mold and a steel reinforcement cage positioning and anchoring device and method. BACKGROUND

[0002] In the field of building engineering, accurate positioning of the steel reinforcement cage and the foam core mold in the construction of prefabricated concrete components is a key link to ensure structural quality. The existing technology mainly relies on fixed positioning rings or scale rods to achieve positioning, which has the following outstanding problems: 1. The traditional method relies on manual measurement and manual adjustment, and the positioning error is large, which is difficult to meet the design requirements of high-precision prefabricated components. For example, during the pouring and vibrating process, the foam core mold is easy to float or sink due to the flow of concrete, resulting in excessive thickness deviation of the top plate and the bottom plate, and even causing the steel reinforcement cage to be offset, directly affecting the safety of the structure.

[0003] 2. The positioning device is mostly custom designed, which has poor universality, resulting in long construction preparation time and high cost; and the manual operation has strong dependence, and the quality consistency is difficult to guarantee. For example, the traditional cushion block needs to be adjusted one by one, and the reuse rate is low, which increases material waste and labor cost.

[0004] 3. There is a lack of real-time monitoring and correction mechanism, and the dynamic error in the construction process is difficult to find and correct in time; the data recording relies on manual operation, and quality tracing and process optimization cannot be achieved. For example, the traditional method cannot quantitatively record the offset data, making it difficult to locate the quality problems afterwards.

[0005] 4. The traditional positioning components (such as plastic positioning rings) are easy to wear or rust, and have low reuse rate, which increases material waste and construction cost. In addition, the structural strength is insufficient, and deformation is easy to occur during concrete pouring, affecting the positioning accuracy.

[0006] The above technical bottlenecks restrict the precision and efficiency of prefabricated concrete component construction, and an modularized and intelligent positioning and anchoring scheme is urgently needed to solve the problem. SUMMARY

[0013] As a preferred scheme of the hollow slab beam foam core mold and steel reinforcement cage positioning and anchoring device, the core mold connecting sleeve and the positioning pin connecting sleeve are respectively threadedly connected to the steel bar connecting heads of two independent anchoring components; the two anchoring components are connected to each other through a bolted joint penetrating through the steel bar fixing holes, and are anchored to the bottom plate steel bars of the steel reinforcement cage.

[0014] As a preferred scheme of the hollow slab beam foam core mold and steel reinforcement cage positioning and anchoring device, the positioning pin is provided with a mounting position for mounting a data acquisition sheet, the data acquisition sheet is connected to an acquisition box through a wire to form a wired monitoring loop, and stable transmission of the data signal of the offset amount of the positioning pin is ensured.

[0015] A positioning and anchoring method of a hollow slab beam foam core mold and steel reinforcement cage positioning and anchoring device, which is suitable for the hollow slab beam foam core mold and steel reinforcement cage positioning and anchoring device described in any one of the preceding embodiments, and comprises the following specific steps: The connecting part is anchored to the foam core mold through the anchoring steel wire passing through the core mold fixing hole; The core mold connecting sleeve of the connecting part is screwed with the steel connecting head of the anchoring part located above, the relative position of the connecting part and the anchoring part is adjusted by rotating the core mold connecting sleeve, and the distance between the foam core mold and the steel reinforcement cage is controlled to meet the requirements; The positioning pin connecting sleeve of the positioning part is screwed with the steel connecting head of the anchoring part located below, and the relative position of the positioning part and the anchoring part is adjusted by rotating the positioning pin connecting sleeve, so that the distance between the bottom plate steel reinforcement of the steel reinforcement cage and the formwork of the pedestal meets the requirement of the protective layer thickness; The upper and lower two independent anchoring parts are fixed to the bottom plate steel reinforcement of the steel reinforcement cage through bolted connections; The positioning pin of the positioning part is inserted into the pedestal positioning hole and anchored to prevent displacement of the device during pouring; After one end of the steel anchor rod passes through the positioning pin fixing hole and the pedestal in sequence, the steel anchor rod is fixed on the steel side mold through the steel backing plate.

[0016] As a preferred scheme of the positioning and anchoring method of the hollow slab beam foam core mold and steel reinforcement cage positioning and anchoring device, the method further comprises the step of monitoring the position of the foam core mold and the steel reinforcement cage in real time, which comprises: A maximum displacement threshold value allowed for the displacement of the foam core mold is preset in the acquisition box, such as ±5mm; When the data of the positioning pin collected by the data acquisition sheet is transmitted to the acquisition box through the wire, if the collected data exceeds the preset threshold value, an alarm signal is triggered; The alarm signal prompts the construction personnel through the sound and light device (such as a buzzer and an LED lamp) of the acquisition box, and is transmitted to the construction management terminal through the wire to trigger a warning state.
