Description

Technical Field

[0001] This utility model belongs to the field of pad block technology, and in particular relates to a double irregular reinforced concrete protective layer pad block. Background Technology

[0002] Double-shaped reinforced concrete protective layer spacers are used to reinforce and protect reinforced concrete components, with the aim of enhancing the strength and service life of reinforced concrete.

[0003] Currently, mortar blocks or plastic blocks are commonly used for reinforced concrete protective layer spacers, which have the following disadvantages and deficiencies: 1. Ordinary reinforced concrete protective layer spacers or plastic blocks are easily damaged during construction due to insufficient strength or material properties, such as being crushed by being stepped on. 2. The purchased spacers are often inconsistent in size, material, or processing, which may lead to instability of the spacers, increasing safety hazards during construction, resulting in the reinforced concrete protective layer not meeting requirements, and thus affecting the overall project quality and service life. 3. Ordinary floor slab reinforced concrete protective layer spacers are installed in two parts. The bottom layer spacers can be placed directly on the bottom slab, while the top layer spacers need to be tied to the bottom layer of reinforcement, and the bottom and top spacers must be on the same cross section. During construction, the top layer spacers often shift due to personnel movement and concrete pouring and vibration, and the bottom layer spacers often twist, affecting the thickness of the protective layer and also impacting on-site acceptance. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and solve the problems of construction difficulties, substandard quality, and safety hazards caused by the existing double irregular reinforced concrete protective layer pad blocks.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a double irregular reinforced concrete protective layer pad block, including a block body, a double irregular pad block top support installed at the upper end of the block body, a surface layer reinforcement placement area opened in the middle of the double irregular pad block top support, and a bottom layer reinforcement placement area opened at the right end of the block body.

[0006] In a preferred embodiment of this invention, a double irregularly shaped pad sidewall is provided at the left end of the block, and a double irregularly shaped pad base is installed at the lower end of the block.

[0007] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0008] The improved rebar spacers have been put into use during construction and have shown good results.

[0009] Improve construction efficiency and economic benefits: The bottom reinforcement placement area and the top reinforcement placement area provide a double-shaped "recessed" part for the entire pad block to tie the reinforcing bar straps to the concrete protective layer of the floor slab. After replacing the double-shaped reinforcement pad block, the number of times the pad block is repeatedly tied and the labor input for placement are significantly reduced, the construction efficiency is greatly improved, and the pad block loss rate is reduced.

[0010] Quality Improvement: The bottom reinforcement placement area and the top reinforcement placement area make the entire pad block form an inward "concave" double-isomorphic reinforcement support area for the reinforced concrete cover of the floor slab. After replacing the double-isomorphic steel reinforcement pad block, the pass rate of the reinforced concrete cover of the floor slab is significantly improved. In the process of preventing the steel reinforcement from rusting, the safety, stability and durability of the structure are also guaranteed, giving full play to the strength of the steel reinforcement itself.

[0011] Therefore, this type of double-shaped pad can effectively prevent the pad itself from shifting during assembly, greatly improving construction efficiency. Attached Figure Description

[0017] Please see Figure 1-4This utility model provides a technical solution: a double-shaped reinforced concrete protective layer pad, comprising a block 6, a double-shaped pad top support 4 installed at the upper end of the block 6, a surface reinforcement placement area 3 formed in the middle of the double-shaped pad top support 4, a bottom reinforcement placement area 2 formed at the right end of the block 6; a double-shaped pad sidewall 5 formed at the left end of the block 6, and a double-shaped pad base 1 installed at the lower end of the block 6; the bottom reinforcement placement area 2 and the surface reinforcement placement area 3 provide a double-shaped "recessed" portion for binding reinforcement strips to the reinforced concrete protective layer of the floor slab, and the double-shaped reinforced concrete protective layer pad is designed with... There are dedicated surface reinforcement placement areas 3 and bottom reinforcement placement areas 2. The block 6, together with the double irregularly shaped pad top support 4, the double irregularly shaped pad side wall 5, and the double irregularly shaped pad base 1, forms a combined structure. It provides stable support for the pad from multiple directions, making it less prone to deformation and damage when subjected to the pressure of concrete pouring and other external impacts. It maintains effective support and protection for the reinforcing bars, enabling the reinforcing bars to be accurately positioned and effectively preventing displacement or misalignment of the reinforcing bars during the concrete pouring process. This ensures the accuracy of the reinforcing bar layout in the engineering structure and improves the overall structural stability.

[0018] The bottom reinforcement placement area 2 and the top reinforcement placement area 3 create a double-anisotropic reinforcement support area for the reinforced concrete cover of the floor slab, forming an inward "concave" shape. The double-anisotropic spacer only requires the bottom reinforcement to be placed into the slot in the bottom reinforcement placement area 2. Because the bottom and top reinforcements are on the same cross-section, the top reinforcement will naturally embed into the slot in the top reinforcement placement area. One spacer can control both the bottom and top reinforcements. Binding with wire ensures its stability. The unique double-anisotropic design clearly divides the functional areas, allowing construction workers to quickly place the corresponding reinforcements according to different areas, enabling a smoother connection between reinforcement binding and subsequent concrete pouring processes, ensuring correct reinforcement placement. Even with personnel movement and concrete pouring and vibration, the spacers are not prone to displacement or twisting. The number of times the spacers need to be repeatedly tied and the amount of manual labor required for placement are significantly reduced. The double-shaped reinforced concrete protective layer spacers are easy to install, reducing the time spent on adjustments and corrections during construction. The installation position can be accurately controlled, reducing errors and rework during construction, improving construction efficiency while saving economic costs. The pass rate of the reinforced concrete protective layer of the floor slab is significantly improved. While preventing the steel bars from corroding, it also ensures the safety, stability and durability of the structure, fully utilizing the strength of the steel bars themselves. Construction quality is improved, construction efficiency is greatly increased, the spacer loss rate is reduced, and construction efficiency and economic benefits are improved.

[0019] These spacers can be used not only at the locations of column and beam reinforcement but also at the locations of double-layer reinforcement in floor slabs. Through their special shape design, the double-shaped spacers allow for more precise control of the reinforced concrete cover thickness, ensuring uniformity and consistency, thereby improving the overall construction quality of the reinforced concrete structure. Furthermore, the double-shaped reinforced concrete cover spacers possess stronger load-bearing capacity and stability, better supporting the reinforcement and preventing displacement or deformation of the reinforcement during concrete pouring and hardening, thus enhancing overall stability and safety.

[0020] It is simple to operate and easy to construct, and can also effectively control the acceptance rate of concrete protective layer.

During the pouring process, attention should be paid to controlling the fluidity of the concrete, the vibration time, and the pouring height to ensure that the concrete is tightly bonded to the spacer blocks and reaches the design strength;

[0046] (2) After the concrete is poured, necessary curing treatment should be carried out to ensure that the concrete reaches the design performance.

[0047] Key technical points

[0048] 1. Shape design

[0049] (1) The key to double irregular reinforced concrete protective layer spacer is its shape design. It needs to be precisely matched with the shape and size of the double irregular steel bars to ensure that the spacer can fit tightly against the steel bars and provide sufficient support.

[0050] (2) The shape design also needs to consider the stability and durability of the pad to ensure that it will not be displaced or damaged during concrete pouring and hardening.

[0051] 2. Material Selection

[0052] (1) The choice of materials is crucial to the performance of the spacer blocks. Materials with sufficient strength, durability and corrosion resistance need to be selected to ensure that the spacer blocks can withstand various stresses and environmental changes during concrete pouring and hardening;

[0053] (2) At the same time, the selection of materials also needs to consider cost-effectiveness and environmental protection in order to meet the requirements of sustainable development.

[0054] 3. Molding process

[0055] (1) The molding process is crucial to ensuring the shape and dimensional accuracy of the pad. It is necessary to work closely with the mold manufacturer to refine the design and employ advanced mold design and molding technology to ensure that the shape and dimensions of the pad meet the design requirements.

[0056] (2) During the molding process, it is also necessary to control parameters such as material fluidity, consistency and vibration time to ensure that there are no defects such as voids and cracks inside the pad.

[0057] 4. Fixing method

[0058] The method of fixing the spacers is crucial to their stability during concrete pouring. Reliable fixing methods, such as tying with steel wire or using steel clamps, need to be designed to ensure that the spacers will not fall off or shift due to vibrations during concrete pouring.

[0059] 5. Optimize construction techniques

[0060] (1) Before pouring concrete, check the position and stability of the spacer blocks again to ensure that the spacer blocks have not been displaced or damaged.

[0061] (2) During the pouring process, pay attention to controlling the fluidity of the concrete and the vibration time to avoid excessive impact and vibration on the spacer blocks;

[0062] (3) After the pouring is completed, timely curing treatment should be carried out to ensure that the concrete and the pad block are tightly bonded and reach the design strength.

[0063] By combining the above implementation steps, this double-shaped pad can effectively prevent the pad itself from shifting during assembly, greatly improving construction efficiency.
