Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a raft foundation reinforced concrete soil pad. Background Technology

[0002] In recent years, with the rapid development of China's construction industry, waterproofing technology has played a crucial role in basement construction. Among these, pre-applied polymer self-adhesive waterproof membranes are widely used in basement waterproofing projects due to their excellent adhesion, waterproofing effect, and ease of construction. However, in actual construction, the installation of raft foundation reinforcement often poses a potential threat to the waterproofing layer.

[0003] The traditional construction method involves using concrete spacers to ensure the thickness of the protective layer between the reinforcing bars and the waterproofing layer after the rebar is tied. This approach has the following main problems:

[0004] 1. Damage to the waterproof layer: During the process of tying the reinforcing bars, because the spacers are placed under the reinforcing bars, the reinforcing bars directly apply force to the waterproof membrane, which can easily cause local damage to the waterproof layer, thereby increasing the risk of leakage.

[0005] 2. Uneven protective thickness: Traditional spacers are not fixedly connected to the reinforcing bars, which makes the spacers prone to shifting when adjusting the position of the reinforcing bars. This cannot guarantee the uniformity and predetermined thickness of the protective layer of the reinforcing bars, which will affect the safety and waterproofing effect of the structure.

[0006] 3. Low construction efficiency: The individual placement and adjustment of the spacers not only increases the number of construction steps, but may also require additional inspection and correction due to insufficient number of spacers or improper placement, thus reducing construction efficiency.

[0007] In view of the above problems, there is an urgent need for a new solution that can effectively avoid direct contact between the steel bars and the waterproof layer, ensure the uniformity of the protective layer thickness, and improve the efficiency and reliability of the construction process. Summary of the Invention

[0008] The purpose of this invention is to provide a raft foundation reinforced concrete soil pad to solve the problems mentioned in the background art.

[0009] The technical solution of the present invention is: a raft foundation reinforced concrete pad block, comprising a precast concrete pad block, wherein a groove is formed at the upper middle part of the precast concrete pad block, a trapezoidal spring assembly is disposed inside the groove, and the lower end of the trapezoidal spring assembly is in contact with the upper middle part of the precast concrete pad block; at the same time, side grooves are formed on both sides inside the groove, and a positioning component is connected to the outward side of the side groove; the positioning component is disposed on the side of the trapezoidal spring assembly, and the trapezoidal spring assembly and the precast concrete pad block are fixedly connected by a movable block and the positioning component.

[0010] Furthermore, the precast concrete pad block has upper grooves on both sides of its upper end, and the trapezoidal spring assembly and the upper grooves are arranged perpendicular to each other.

[0011] Furthermore, the trapezoidal spring assembly includes slotted sidewalls, which are disposed on both sides of the trapezoidal spring assembly. Multiple movable slots are provided on the slotted sidewalls, which are disposed on the outward side of the positioning assembly. The movable slots and movable blocks are arranged in a one-to-one correspondence, and the movable blocks are disposed inside the movable slots.

[0012] Furthermore, the depth of the movable groove is not less than the thickness of the movable block.

[0013] Furthermore, the trapezoidal spring assembly also includes a central spindle, which is located in the middle of the interior of the trapezoidal spring assembly. A tension button is provided at the upper end of the central spindle, which is located in the middle of the upper end of the trapezoidal spring assembly. A bottom fixing block is provided at the lower end of the central spindle, which is located at the lower interior of the trapezoidal spring assembly.

[0014] Furthermore, the trapezoidal spring assembly also includes a tension shaft, and multiple tension shafts are provided, with each tension shaft corresponding to a movable block. One end of each tension shaft is connected to a movable block, and the other end of each tension shaft is connected to a central main shaft.

[0015] Furthermore, the positioning component includes a connecting rod disposed inside the side groove. At the same time, positioning blocks are provided at both ends of the outward-facing side of the connecting rod. Positioning rods are provided on the opposite sides of the positioning blocks, and the two oppositely positioned positioning rods are disposed on both sides of the movable block.

[0016] Furthermore, the positioning rod is connected to the side of the connecting rod via a connecting block, and the connecting block contains multiple swing springs.

[0017] Furthermore, the end side of the positioning rod is connected to the side of the positioning block via multiple positioning springs.

[0018] This invention provides an improved version of a raft foundation reinforced concrete soil pad, which has the following improvements and advantages compared to the prior art:

[0019] Firstly, this invention achieves rapid positioning and fixing of reinforcing bars through the cooperative design of trapezoidal spring components and positioning components, eliminating the need for complex tools and lengthy manual adjustments, significantly shortening the construction cycle and improving work efficiency on the construction site. At the same time, precise positioning of reinforcing bars helps improve the quality of concrete pouring, preventing displacement of reinforcing bars during the pouring process and ensuring the uniformity and strength of the concrete structure.

[0020] Secondly, the present invention, through the positioning rod and positioning spring in the positioning component, can ensure the precise alignment and firm fixation of the reinforcing bars, thereby reducing structural safety hazards caused by reinforcing bar misalignment and enhancing the overall stability and safety of the building structure.

[0021] Thirdly, the elastic design of the trapezoidal spring assembly of the present invention allows the pad to adapt to steel bars of different diameters, eliminating the need to prepare multiple pads for steel bars of different specifications, thereby reducing material costs and management complexity.

[0022] Fourthly, the design of the movable block and positioning component of this invention simplifies the maintenance of the pad and allows for quick replacement of worn parts, thereby extending the service life of the pad and reducing maintenance costs.

[0023] Fifthly, the present invention allows the operator to easily control the tension and relaxation of the trapezoidal spring assembly through the setting of the stretch button, thereby realizing the quick clamping of the steel bars, reducing the difficulty of operation and the reliance on professional skills.

[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be discussed or described in detail in the description of the subsequent figures.

[0036] refer to Figures 1-5 This embodiment provides a raft foundation reinforced concrete soil pad, which includes a trapezoidal spring assembly 3, a positioning assembly 4, and a precast concrete pad 5. The precast concrete pad 5 has a groove 2 at its upper center, and the trapezoidal spring assembly 3 is disposed inside the groove 2, with its lower end fitting against the upper center of the precast concrete pad 5. Simultaneously, side grooves 6 are formed on both sides of the groove 2, and the inward-facing side of the positioning assembly 4 connects to the outward-facing side of the side groove 6. The positioning assembly 4 is located on the side of the trapezoidal spring assembly 3. Specifically, the trapezoidal spring assembly 3 and the precast concrete pad 5 are fixedly connected by a movable block 1 and the positioning assembly 4.

[0037] In this embodiment, upper grooves 7 are provided on both sides of the upper end of the precast concrete pad 5. The upper grooves 7 are located on both sides of the groove 2, and the trapezoidal spring assembly 3 and the upper grooves 7 are arranged perpendicularly to each other. It is worth noting that the upper grooves 7 can be used for the reinforcing bars in the X direction at the bottom of the raft slab, and the trapezoidal spring assembly 3 can be used for the reinforcing bars in the Y direction at the bottom of the raft slab. Specifically, when the precast concrete pad 5 is poured, it is cast with high-strength concrete to a specific size, and it is ensured that the upper part of the middle of the precast concrete pad 5 has a groove 2, and the size of the groove 2 must match the subsequent trapezoidal spring assembly 3.

[0038] Specifically, the trapezoidal spring assembly 3 includes slotted sidewalls 9 and a central spindle 13. The slotted sidewalls 9 are located on both sides of the trapezoidal spring assembly 3, and multiple movable slots 10 are formed on the slotted sidewalls 9. The movable slots 10 are located on the outward-facing side of the positioning assembly 4, and each movable slot 10 corresponds to a movable block 1. The movable blocks 1 are located inside the movable slots 10. It is worth noting that the depth of the movable slots 10 is not less than the thickness of the movable blocks 1.

[0039] Furthermore, the central spindle 13 is located in the middle of the trapezoidal spring assembly 3. A tension button 8 is located at the upper end of the central spindle 13, in the middle of the upper part of the trapezoidal spring assembly 3. A bottom fixing block 11 is located at the lower end of the central spindle 13, inside the lower part of the trapezoidal spring assembly 3. It is worth noting that the movable block 1 and the central spindle 13 are connected via a tension shaft 12. Specifically, multiple tension shafts 12 are provided, and each tension shaft 12 corresponds to one movable block 1. One end of each tension shaft 12 is connected to the movable block 1, and the other end is connected to the central spindle 13. This ensures that the tension shaft 12 can drive the movable block 1 to move along the movable groove 10 under the action of the central spindle 13.

[0040] In this embodiment, the positioning component 4 includes a connecting rod 18, which is disposed inside the side groove 6. Positioning blocks 14 are provided at both ends of the outward-facing side of the connecting rod 18, and the end side of the positioning rod 15 is connected to the side of the positioning block 14 via multiple positioning springs 16. Simultaneously, positioning rods 15 are provided on opposite sides of the positioning blocks 14, and two oppositely positioned positioning rods 15 are disposed on both sides of the movable block 1. Further, the positioning rods 15 are connected to the side of the connecting rod 18 via a connecting block 17, and multiple swing springs 19 are disposed inside the connecting block 17. That is, when the connecting rod 18 is inserted into the side groove 6, and the positioning blocks 14 are fixed to both ends of the connecting rod 18 by the positioning springs 16, the positioning rods 15 pass through both sides of the movable block 1 and are connected to the connecting rod 18 via the connecting block 17. The swing springs 19 are disposed inside the connecting block 17 to ensure that the positioning rods 15 can swing as the movable block 1 moves, thereby achieving the positioning of the reinforcing bar.

[0041] Specifically, when using the raft foundation reinforced concrete pad block provided in this embodiment, pulling the tension button 8 will cause the central spindle 13 to drive the tension shaft 12 to stretch upward, thereby moving the movable block 1 into the movable groove 10. Then, the trapezoidal spring assembly 3 is inserted into the groove 2 and fixed. Pressing the tension button 8 will cause the central spindle 13 to drive the tension shaft 12 to move downward, causing the movable block 1 to move out of the movable groove 10. This allows the movable block 1 to be positioned between the two positioning rods 15, thus creating space for the insertion of the reinforcing bar.

[0042] It is worth noting that when the reinforcing bar is placed in the upper groove 7, aligned with the center of the trapezoidal spring assembly 3, and the tension button 8 is pulled up, the positioning rod 15 will swing outward accordingly. When the tension button 8 is then pressed down, the movable block 1 will reset under the rebound force of the tension shaft 12, and the positioning rod 15 will swing back to both sides of the reinforcing bar, and tightly clamp the reinforcing bar through the action of the positioning spring 16, thereby achieving rapid positioning and fixing of the reinforcing bar.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
