Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically, it is a prefabricated cover plate construction mold. Background Technology

[0002] With the continuous advancement of construction technology, the scale and complexity of buildings are increasing, and the limitations of traditional post-cast strip construction methods, such as long closure times and complex construction joint treatment, are becoming increasingly apparent. The widespread application of prefabrication technology in the construction field provides a new approach to post-cast strip construction. It solves problems such as poor appearance quality and large dimensional deviations associated with traditional cast-in-place slabs, meeting the higher requirements of construction engineering for construction precision and quality.

[0003] In traditional post-pouring strip construction, improper protection often leads to the entry of debris and sewage during the post-pouring strip placement period, affecting the quality of subsequent pouring; the risk of personnel or objects falling is also relatively high.

[0004] Therefore, the known precast cover plate construction molds have the aforementioned inconveniences and problems. Utility Model Content

[0005] The purpose of this utility model is to provide a safe and reliable precast cover plate construction mold.

[0006] To achieve the above objectives, the technical solution of this utility model is: The core concept of this utility model lies in providing a precast cover plate construction mold that can be directly installed during the main structure construction stage, possesses good waterproof performance, and improves construction safety. This mold addresses the problems of long construction cycles, easy leakage at construction joints, high risk of debris falling, and delays in subsequent processes associated with traditional post-pouring strips, proposing a precast and standardized overall solution.

[0007] The technical solution of this utility model mainly includes the following basic design ideas: By setting matching grooves on the edge of the steel plate and placing water-stopping components in the grooves, the junction between the cover plate and the post-cast strip has reliable waterproof performance. A casting through hole is set in the center of the steel plate, and a pipe is pre-installed in the through hole, so that the subsequent concrete pouring can be completed without removing the cover plate, ensuring construction continuity and ease of operation. By using a modular arrangement of panels, multiple precast cover plates can be sequentially connected along the direction of the post-pouring strip to form a continuous working surface. This not only covers and protects the post-pouring strip but also provides a safe operating platform for subsequent construction procedures.

[0008] Based on the above overall concept, this utility model can significantly improve the problems of joint leakage, construction waiting time, and safety hazards existing in traditional processes, and achieve the following beneficial effects: 1. The prefabricated cover plate device has a simple structure and is easy to manufacture; 2. Precast cover plates can be installed in a timely manner during the main structure construction stage to form a continuous working surface, allowing subsequent decoration, equipment installation and other processes to be carried out in advance; 3. Reduce construction waiting time, shorten the overall construction period, and speed up the construction progress. Attached Figure Description

[0011] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0012] Please see now Figure 1 . Figure 1 This is a schematic diagram of the prefabricated cover plate structure according to an embodiment of the present invention. As shown in the figure, the steel plate 4 is welded into the required shape. In this embodiment, the cross-section of the steel plate is trapezoidal, and grooves are provided at the two base corners of the trapezoid. The water-stopping effect is achieved by adding expansion water-stop strips 2 in the grooves. Unlike the prior art that relies on simply laying waterproof material at the joint of the post-pouring strip, this embodiment prefabricates the water-stopping component and embeds it into the mold, so that the waterproofing measure is formed in one step when the mold is installed, avoiding the drawbacks of repeated repairs at the construction joint.

[0013] The dimensions of the precast cover plate mold are adjusted according to the actual site conditions. The width of each side of the molded cover plate is 100mm wider than the width of the post-cast strip. The length is 2000mm, which allows for the transportation of the precast cover plate mold using equipment such as tower cranes and forklifts. This precast size design not only facilitates hoisting but also avoids dimensional deviations caused by settlement and shrinkage during traditional on-site casting through standardized production, thus ensuring the overall sealing performance of the assembled cover plate.

[0014] A 150mm diameter steel pipe is pre-installed on the steel plate for later concrete pouring. This design allows concrete pouring to be completed without removing the cover plate, significantly improving the efficiency of subsequent processes compared to traditional cast-in-place cover plates. Simultaneously, the steel pipe acts as a guide during pouring, ensuring the fluidity and density of the concrete.

[0015] Figure 2This is a schematic diagram illustrating the usage of the precast cover plate according to an embodiment of the present invention. When using the precast cover plate according to this embodiment, a steel plate is placed over the post-pouring strip 1 as needed, and the precast cover plates can be arranged and connected longitudinally. The splicing and connection of multiple cover plates not only achieves continuous coverage of the post-pouring strip but also forms a temporary working platform, effectively avoiding the risk of personnel and debris falling during construction, further improving construction safety. This invention has substantial features and significant technological advancements. The precast cover plate construction mold of this invention solves the problems of traditional precast cover plates requiring re-circular chamfering and the lack of waterproofing at the joint between the traditional precast cover plate and the original basement, which could only achieve waterproofing through waterproof materials. This construction device is convenient and quick to install, and its waterproofing effect is significantly better than traditional construction processes, showing good market application prospects.

[0016] Precast cover plates are characterized by high strength and good sealing performance, effectively covering the post-pouring strip to prevent debris from falling in, sewage from seeping in, and steel reinforcement from corroding. This ensures structural safety before the post-pouring strip is closed and the quality of subsequent pouring. Simultaneously, it provides reliable safety protection for the construction site, reducing the occurrence of accidents. Traditionally, post-pouring strips can only be closed after the main structure is completed and a considerable period of settlement and shrinkage stabilization has passed. During this period, the structures on both sides of the post-pouring strip are discontinuous, affecting subsequent construction processes. Precast cover plates can be installed promptly during the main structure construction phase, creating a continuous working surface. This allows subsequent decoration, equipment installation, and other processes to begin earlier, reducing waiting time, shortening the overall construction period, and accelerating the construction progress.

[0017] The precast cover plate construction mold of this utility model has been applied in the Beining Start-up Area Project and has achieved good economic benefits.

[0018] The above embodiments are for illustrative purposes only and are not intended to limit the scope of this utility model. Those skilled in the art can make various modifications and variations without departing from the spirit and scope of this utility model. Therefore, all equivalent technical solutions should also fall within the scope of this utility model and should be defined by the claims.
