Embodiment 1）

[0060] See figure 1 In this embodiment, the basement floor 100 of the advanced water-stopping post-casting strip structure is fixedly connected to the foundation of the basement. The upper surface of the foundation of the basement is composed of each datum unit and trapezoidal construction grooves with upward openings arranged between adjacent datum units. Each datum unit is located on the same horizontal plane and arranged parallel to each other. Each trapezoidal construction groove is located below the reference plane, and its upper left edge is connected with the right edge of the reference plane unit on the left, and its upper right edge is connected with the left edge of the datum unit on the right .

[0061] The basement floor 100 is composed of respective foundation floor portions 100a and respective respective post-cast tape portions 100b connected between the respective foundation floor portions 100a.

[0062] The foundation floor part 100a includes a concrete cushio...

Embodiment 2）

[0120] See image 3 and Figure 4 , the rest of this embodiment is the same as Embodiment 1, except that the leading waterstop 3 also includes a baffle 39 . The baffle plate 39 is divided into the lower left baffle plate 39-1 located at the lower left, the lower right baffle plate 39-2 located at the lower right, and the upper left baffle plate 39-3 located at the upper left according to the difference of the upper, lower, left, and right positions. and the upper right fender 39-4 located on the upper right. Lower left baffle plate 39-1, lower right baffle plate 39-2, upper left baffle plate 39-3 and upper right baffle plate 39-4 all have one group.

[0121] Each lower left baffle 39-1 is located on the second concrete pad 31-2 of the corresponding array of concrete pads 31, and each lower left baffle 39-1 is distributed sequentially in the front-rear direction until it penetrates in the front-rear direction The trapezoidal construction slot where it is located. Each lower...

Abstract

The invention provides a basement bottom plate having an advanced-waterstop post-cast strip structure. The basement bottom plate comprises various bases and various corresponding post-cast strips connected among the bases. Each post-cast strip comprises a concrete backing layer, a waterproof layer, a waterproof protective layer, an advanced-waterstop strip and a post-cast strip, wherein the advanced-waterstop strip comprises cast-in-situ concrete, a concrete cushion block, a lower filling component, a lower left reinforcement frame, a lower right reinforcement frame, a waterstop component, an upper filling component, an upper left reinforcement frame and an upper right reinforcement frame, the post-cast strip comprises main reinforcement, a reinforcement net, a steel plate net, a fine-mesh steel wire net, advanced-cast concrete and post-cast concrete, the waterstop component comprises a rubber waterstop belt, a flat iron sheet and fastening bolts, and each filling component comprises a filling plate, a formwork and a plastic cushion block. The advanced-waterstop post-cast strip structure overcomes defects that the rubber waterstop of the existing advanced-waterstop post-cast strip is easy to deviate and crack, the filing materials thereof are easy to deform and the like, and accordingly can prevent the basement bottom plate from water leakage and seepage.

Description

technical field [0001] The invention relates to a component provided with an advanced water-stop post-cast strip in the field of building construction, in particular to a component provided with an advanced water-stop post-cast strip in the basement of a building. Background technique [0002] In order to prevent harmful cracks that may occur in cast-in-place reinforced concrete structures due to uneven temperature and shrinkage during construction, according to the requirements of the design or construction specifications, temporary construction joints are left at the corresponding positions of the foundation floor, walls, and beams during the preliminary construction. The temporary construction joints temporarily divide the structure into several parts, and after the internal contraction of the components, concrete is poured and tamped at each temporary construction joint in the later construction to connect the structure into a whole. The post-pouring belt is the conc...
