Abstract
The invention discloses a thermal insulation soundproof floor and a construction method. The thermal insulation soundproof floor is characterized by comprising a trough-type pre-cast concrete plank, a cast-in-place concrete and a pre-cast concrete cushion block, wherein the thickness of the thermal insulation soundproof floor is 12 to 18 centimeters; the height of the trough-type pre-cast concrete plank is 3 to 5 centimeters, while the length is 0.8 to 1.2 centimeters; rabbets of adjacent trough-type pre-cast concrete planks face opposite directions; the adjacent trough-type pre-cast concrete planks form a rectangular hole with a diameter of 1/3 based on the length of the trough-type plank; a hole serving as a working hole is formed in the middle of the trough-type concrete plank and the diameter of the hole is 25 to 30 centimeters; the distance from the trough-type concrete plank to the floor edge is 30 to 50 centimeters; the cast-in-place concrete is covered outside the trough-type pre-cast concrete plank; the trough-type pre-cast concrete plank is positioned in the middle of the cast-in-place concrete; the pre-cast concrete cushion block is used as a support of the trough-type concrete plank; the pre-cast concrete cushion block is a cuboid with the length of 15 centimeters, the width of 15 centimeters and the height of the between 4 and 8 centimeters; and the concrete strength is one grade higher than the designed floor strength. The thermal insulation soundproof floor has a simple structure and a good thermal insulation effect.
Description
Technical field
The present invention relates to a kind of thermal-insulating and sound-insulating floor and job practices, be applicable to building field.
Background technology
Traditional floor adopts precast concrete plank or cast-in-situ concrete usually; Precast concrete plank structural performance difference and leaking easily; The cast-in-place concrete heat-preservation soundproof effect is not good; Can organically combine the advantage of these two kinds of floors, producing the floor that sound insulation is good, cost is low be the problem of pendulum in face of engineers and technicians.In addition, if add heat-insulating and noise-insulating material, obviously can receive good heat preservation and soundproof effect at ordinary concrete.
Summary of the invention
The technical problem that the present invention solves provides a kind of thermal-insulating and sound-insulating floor, solves the problem that traditional floor heat preservation and soundproof effect is bad or leak.
The present invention includes precast concrete groove type plate, cast-in-situ concrete and precast concrete cushion block; Thermal-insulating and sound-insulating floor thickness is 12～18cm, and precast concrete groove type plate height is 3～5cm, and length is 0.8～1.2m; Contiguous prefabricated concrete pit template notch is towards on the contrary; Contiguous prefabricated concrete pit template forms the rectangle hole, and rectangle hole length is 1/3 groove type plate length, thereby produces the heat preservation and soundproof effect.Hole is set as working hole in the middle of the concrete pit template, hole diameter is 25～30cm, is convenient to the concrete concrete vibrating.The concrete pit template is 30～50cm from the floor Edge Distance.Cast-in-situ concrete is wrapped in precast concrete groove type plate outside, and the precast concrete groove type plate is positioned in the middle of the cast-in-situ concrete.The precast concrete cushion block supports as the concrete pit template, and the precast concrete cushion block is a cuboid, and length and width are 15cm, highly are 4～8cm, and concrete strength is than the high one-level of floor design strength.
Construction sequence comprises:
(1) installs slab form;
(2) the floor lower rebar is set;
(3) place the precast concrete cushion block;
(4) place the concrete pit template;
(5) the floor upper reinforcement is set;
At four jiaos of settings of floor
reflection reinforcing bar, avoid stress to concentrate and cause the floor cracking;
(6) concreting;
Concrete adopts concrete special, admixture glass microballoon in ordinary concrete, corresponding minimizing stone consumption simultaneously.The recruitment of glass microballoon and stone reduction are adjusted ordinary concrete according to the varying strength concrete.For intensity is the concrete of C35, and the glass microballoon recruitment is 21% of an ordinary concrete Central Plains stone amount, and the stone reduction is 27% of an ordinary concrete Central Plains stone amount; For intensity is the concrete of C30, and the glass microballoon recruitment is 17% of an ordinary concrete Central Plains stone amount, and the stone reduction is 22% of an ordinary concrete Central Plains stone amount; For intensity is the concrete of C25, and the glass microballoon recruitment is 14% of an ordinary concrete Central Plains stone amount, and the stone reduction is 18% of an ordinary concrete Central Plains stone amount; For intensity is the concrete of C20, and the glass microballoon recruitment is 12% of an ordinary concrete Central Plains stone amount, and the stone reduction is 15% of an ordinary concrete Central Plains stone amount;
(7) concrete curing;
(8) form removable.
Simple structure of the present invention, heat preservation and soundproof is effective.

The specific embodiment
Describe the present invention below in conjunction with accompanying drawing.
Fig. 1 is the thermal-insulating and sound-insulating floor sketch map.The present invention includes precast concrete groove type plate 1, cast-in-situ concrete 2 and precast concrete cushion block 3; Thermal-insulating and sound-insulating floor thickness is 15cm, and concrete strength is C25, and precast concrete groove type plate 1 highly is 4cm; Length is 1.2m; Contiguous prefabricated concrete pit template 1 notch is towards on the contrary, and contiguous prefabricated concrete pit template 1 forms the rectangle hole, and rectangle hole length is 0.4m.Hole is set as working hole in the middle of the concrete pit template 1, hole diameter is 25cm, and concrete pit template 1 is 40cm from the floor Edge Distance.Cast-in-situ concrete 2 is wrapped in precast concrete groove type plate 1 outside, and precast concrete groove type plate 1 is positioned in the middle of the cast-in-situ concrete 2.Precast concrete cushion block 3 is a cuboid, and length and width are 15cm, highly is 55mm, and concrete strength is C30.
