Description

Technical Field

[0001] The invention relates to the technical field of winter building construction, in particular to a method for heat preservation covering of a concrete floor during winter construction. Background Art

[0002] During winter construction, in order to prevent the concrete from freezing and affecting the construction quality, quilts will be laid for insulation after the concrete floor is poured. In the past, the quilts were covered only after the concrete surface had initially solidified. Workers walking on the initially solidified concrete floor may cause the concrete floor to collapse due to manual trampling, which damages the surface of the concrete floor. At the same time, there is a risk of freezing the concrete while waiting for the initial solidification of the concrete surface. A method for insulation covering of concrete floors during winter construction is provided to solve the above problems. Summary of the invention

[0003] The present invention aims to solve the above problems, thereby providing a method for heat insulation covering of concrete floor slabs during winter construction.

[0004] The present invention solves the above-mentioned problem by adopting the following technical solution:

[0005] A method for heat insulation covering of concrete floor slabs during winter construction is carried out according to the following steps:

[0006] Step 1: Use conventional construction methods to build the support formwork and arrange the steel mesh on the support formwork;

[0007] Step 2: Place multiple support frames made in advance in a straight line above the support formwork. The support frame includes two embedded parts and a cross bar. The embedded parts are composed of an embedded plate and two vertical poles embedded in the cast-in-place concrete floor slab. The bottom ends of the two vertical poles are vertically welded to the embedded plates. The top ends of the two vertical poles extend upward from the casting elevation of the cast-in-place concrete floor slab. The four vertical poles of the two embedded parts are located on the same facade and are connected to the same cross bar. The cross bar and the vertical poles are connected by welding. The height of the cross bar is higher than the casting elevation of the cast-in-place concrete floor slab. After the support frame is placed, the vertical poles of the embedded parts are tied to the laid steel mesh to position the support frame as a whole.

[0008] Step 3: Place two parallel slide rails on top of the multiple support frames. The two slide rails are respectively located between the two vertical bars of the two embedded parts of the support frames and welded to the cross bars. Both ends of the slide rails extend outside the main building to the edge of the external scaffolding pedal.

[0009] Step 4: Place a skateboard on one end of the two slide rails near the edge of the outer scaffolding pedal. A pulley is provided at the bottom of the skateboard to enable the skateboard to slide on the two slide rails. Traction ropes are connected to both sides of the skateboard. The pulley cooperates with the slide rails, and the skateboard can move on the slide rails.

[0010] Step 5: Conventional construction, pouring concrete floor slab;

[0011] Step 6: After the concrete pouring is completed, the worker goes up from the external scaffolding to the top of the skateboard, stands on the skateboard, and moves to the position above the floor slab by pulling the traction rope with the help of the staff on the external scaffolding. During the movement, the worker cooperates with the staff on the external scaffolding to cover the concrete floor slab with a layer of plastic film and quilt in turn.

[0012] Compared with the prior art, the present invention adopting the above technical solution has the following outstanding features:

[0013] When the method described in the present invention is used for construction, after the concrete floor is poured, the quilt can be quickly laid on the concrete floor to prevent the concrete from freezing; when in use, the worker stands on the skateboard and pulls the traction rope through the personnel on the external scaffolding to achieve the position movement above the floor. During the movement, there is no need to contact the concrete floor to prevent damage to the surface of the concrete floor. The worker can easily cooperate with the staff on the external scaffolding to lay the quilt on the concrete floor, and the operation is simple and convenient. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Step 1: Use conventional construction methods to build the support formwork 8, and arrange a steel mesh on the support formwork 8;

[0020] Step 2: Place multiple support frames 1 prepared in advance in a straight line above the support formwork 8. The support frame 1 includes two embedded parts 11 and a cross bar 12. The embedded part 11 is composed of an embedded plate 111 and two vertical poles 112 embedded in the cast-in-place concrete floor. The bottom ends of the two vertical poles 112 are vertically welded to the embedded plate 111. The top ends of the two vertical poles 112 are higher than the casting elevation 7 of the cast-in-place concrete floor and extend upward. The four vertical poles 112 of the two embedded parts 11 are located on the same facade and are commonly connected to the same cross bar 12. The cross bar 12 and the vertical poles 112 are connected by welding. The height of the cross bar 12 is higher than the casting elevation 7 of the cast-in-place concrete floor. After the support frame 1 is placed, the vertical poles 112 of the embedded part 11 are tied to the laid steel mesh to position the support frame 1 as a whole.

[0021] Step 3: Place two parallel slide rails 2 above the multiple support frames 1. The two slide rails 2 are respectively located between the two vertical rods 112 of the two embedded parts 11 of the support frame 1 and are welded to the crossbar 12. Both ends of the slide rails 2 extend outside the building body to the edge of the external scaffolding pedal;

[0022] Step 4: Place a slide plate 4 on one end of the two slide rails 2 close to the edge of the outer scaffolding pedal. A pulley 5 is provided at the bottom of the slide plate 4 to enable the slide plate 4 to slide on the two slide rails 2. Traction ropes 3 are connected to both sides of the slide plate 4. The pulley 5 cooperates with the slide rails 2, and the slide plate 4 can move on the slide rails 2.

[0023] Step 5: Conventional construction, pouring concrete floor slab;

[0024] Step 6: After the concrete pouring is completed, the worker goes up the external scaffolding to the top of the skateboard 4, stands on the skateboard 4, and pulls the traction rope 3 through the personnel on the external scaffolding to move the position above the floor slab. During the movement, the worker cooperates with the staff on the external scaffolding to cover the concrete floor slab with a layer of plastic film and a quilt in turn.

[0025] Covering with plastic film is a maintenance measure to ensure that the moisture of concrete does not lose.

[0026] When the method described in the present invention is used for construction, after the concrete floor is poured, the quilt can be quickly laid on the concrete floor to prevent the concrete from freezing; when in use, the worker stands on the skateboard and pulls the traction rope through the personnel on the external scaffolding to achieve the position movement above the floor. During the movement, there is no need to contact the concrete floor to prevent damage to the surface of the concrete floor. The worker can easily cooperate with the staff on the external scaffolding to lay the quilt on the concrete floor, and the operation is simple and convenient.
