In order to save costs, most designs use waterproof membranes without protective layers. Compared with traditional SBS waterproof membranes, this waterproofing method can greatly reduce costs, but there are also many problems, especially the protection of the waterproof layer. Because there is no protective layer, the waterproof layer is in direct contact with the steel bars, and the steel bars often pierce and damage the waterproof layer, causing damage to the waterproof layer and causing a major leakage risk. Summary of the invention

The height-adjusting spacer 4 and the positioning block base 5 are in the shape of a cuboid and have the same cross-sectional size as the cross-sectional size of the steel bar positioning spacer 1. A tenon 6 is fixedly connected to the center position of the top surface of each of the height-adjusting spacer 4 and the positioning block base 5. A groove 3 is opened at the center position of the bottom surface of the height-adjusting spacer 4. The tenon 6 corresponds to the groove 3 and is inserted into the groove 3. The bottom surface of the positioning block base 5 is fixedly connected to the adhesive layer 7, and the adhesive layer 7 is fixedly connected to the elastomeric asphalt waterproof coiled material 8.

[0022] In the present utility model, the steel bar positioning cushion block 1 and the positioning block base 5 are integrally made of cement mortar with a strength greater than M20. The steel bar positioning cushion block 1 and the positioning block base 5 integrally made of cement mortar with a strength greater than M20 ensure the overall strength and the long-term durability of the present utility model.

[0023] In the present utility model, the adhesive layer 7 is made of epoxy resin glue. The adhesive layer 7 made of epoxy resin glue has good water resistance and adhesive strength, enabling the elastomeric asphalt waterproofing membrane 8 to be firmly fixed on the adhesive layer 7 even in a damp environment such as a basement. Moreover, the adhesive layer 7 formed after the epoxy resin glue cures has relatively high hardness and strength, which helps to improve the overall stability of the present utility model.

[0024] In the present utility model, anti-slip grooves 9 are provided on the arc-shaped groove 2, and the anti-slip grooves 9 are fixedly connected to the arc-shaped groove 2. The stability of the steel bar can be further improved through the anti-slip grooves 9 on the arc-shaped groove 2.

[0025] In the present utility model, a elevation scale 10 is provided on the height-adjusting cushion block 4, and the elevation scale 10 is fixedly connected to the height-adjusting cushion block 4. The elevation scale 10 on the height-adjusting cushion block 4 enables construction workers to conveniently select appropriate height-adjusting cushion blocks for splicing.

[0026] In this implementation plan: After the pre-laid non-protective waterproofing membrane is laid, before installing and tying the steel bars, the construction worker holds the positioning block base 5 and fixes one side of the elastomeric asphalt waterproofing membrane 8 adhered to the positioning block base 5 by the adhesive layer 7 downward on the waterproofing membrane, making the pre-laid waterproofing membrane of the foundation slab in flexible contact with the positioning block base 5 to reduce damage to the waterproofing membrane. After the positioning block base 5 is fixed, according to the elevation of the tied steel bars, select a height-adjusting cushion block 4 with a corresponding height or splice multiple height-adjusting cushion blocks 4 into a corresponding height. The elevation scale 10 on the height-adjusting cushion block 4 enables construction workers to conveniently select appropriate height-adjusting cushion blocks for splicing. During splicing, insert the tenon 6 on the lower height-adjusting cushion block 4 into the groove 3 on the upper height-adjusting cushion block 4, and the height of the height-adjusting cushion block 4 can then conform to the elevation of the tied steel bars. Then, align the groove 3 at the lowermost end of the spliced height-adjusting cushion block 4 with the tenon 6 on the positioning block base 5 and insert them to start installing the steel bar positioning cushion block 1. When installing the steel bar positioning cushion block 1, insert the groove 3 at the lower end of the steel bar positioning cushion block 1 onto the tenon 6 at the uppermost end of the height-adjusting cushion block 4. The orientation of the arc-shaped groove 2 at the upper end of the steel bar positioning cushion block 1 is the same as that of the steel bar. The arc-shaped groove 2 can effectively position the steel bar into the arc-shaped groove 2 to prevent the steel bar from detaching from the steel bar positioning cushion block 1. The stability of the steel bar can be further improved through the anti-slip grooves 9 on the arc-shaped groove 2 to prevent the steel bar from sliding during construction. After the steel bar positioning cushion block 1 is installed, the tying of the steel bars can be carried out.
