Description

Technical Field

[0001] The invention relates to the technical field of cast-in-place counter-slope, and in particular to an installation and positioning device for a secondary cast-in-place counter-slope template for a floor, and a construction method. Background Art

[0002] Conventional secondary anti-slope construction is mainly to wait until the board surface strength is reached, and then carry out the nailing wood formwork box formwork construction. The reinforcement method uses formwork or square wood nails to reinforce the anti-slope formwork and the floor. The following problems are often encountered:

[0003] (1) Ordinary wooden formwork is used as the counter-slope mold. The strength of the wooden formwork itself is low, resulting in poor molding effect and low material turnover rate. After being used three times, the wooden box basically needs to be re-ordered. Otherwise, the quality of the molded counter-slope is poor, and rework and repair are required later. It is also time-consuming to make the mold. The walls of the kitchen, bathroom, and balcony areas all need to be cast in place, which is labor-intensive and requires a large amount of formwork;

[0004] (2) The anti-slope reinforcement tool generally uses broken templates and small square wood to fix and reinforce with cement nails. Although this reinforcement method is simple and easy to operate, directly reinforcing with cement nails will damage the original anti-slope template and floor structure. In addition, since this reinforcement method is flexible, the amount of reinforcement required is also large. The reinforcement materials can basically only be used once before being scrapped, resulting in a lot of material waste;

[0005] (3) Conventional reinforcement methods can easily cause the formwork to shift or expand during the concrete pouring process, which makes the subsequent processing cumbersome and greatly increases the rework costs. Summary of the invention

[0006] In view of the deficiencies in the above-mentioned background technology, the present invention proposes a device for installing and positioning a secondary cast-in-place anti-slope formwork for a floor and a construction method, which solves the problem of poor effect of the anti-slope reinforcement method in the prior art.

[0007] The technical solution of the present invention is achieved in this way:

[0008] A device for installing and positioning a secondary cast-in-place anti-slope formwork for a floor comprises at least one pair of anti-slope side panels arranged opposite to each other, clamps clamped at both ends of the anti-slope side panels and a plurality of adjustable clamps clamped at the upper sides of the anti-slope side panels; a full-length steel plate is connected between the clamps at both ends of the anti-slope side panels; and embedded bolts or embedded nuts are connected to the anti-slope side panels and / or the clamps.

[0009] Furthermore, the adjustable clamp includes two U-shaped clamps for clamping on a pair of anti-ridge side plates respectively, one of the two U-shaped clamps is connected to a sliding rod, and the sliding end of the sliding rod penetrates into the other U-shaped clamp and slides in conjunction.

[0010] Furthermore, a fastening bolt for tightening the sliding rod is provided on the U-shaped clamping plate close to the sliding end of the sliding rod.

[0011] Furthermore, a clamping plate that slidably cooperates with the full-length steel plate is provided on the side of the clamp, and a fastener is provided between the clamping plate and the full-length steel plate.

[0012] Furthermore, the clamping plate is provided with a slot for the full-length steel plate to pass through, and the fastener is a bolt that is penetrated through the clamping plate and is used to tighten the full-length steel plate.

[0013] Furthermore, a base plate is provided on the clamp, and fixing bolts are passed through the base plate for connecting the embedded nuts.

[0014] Furthermore, a water-stop pad is sleeved on the fixing bolt, and the water-stop pad is arranged close to the embedded nut and / or the nut end of the fixing bolt.

[0015] Furthermore, the fixing bolt passes through the floor formwork, and one end of the fixing bolt passing through the floor formwork is connected with a lower bolt and a gasket.

[0016] Furthermore, a diagonal brace is provided between the bottom plate and the side wall of the clamp.

[0017] The construction method of the secondary cast-in-place anti-slope formwork installation positioning device for the floor comprises the following steps:

[0018] S1. Set embedded nuts on the laid floor formwork;

[0019] S2. Tie steel bars and pour concrete;

[0020] S3. Install the anti-slope side plate at the preset anti-slope position, install clamps at both ends of the anti-slope side plate, and fix the clamps to the embedded nuts with fixing bolts, then install the corresponding full-length steel plate, and install adjustable clamps on both sides of the anti-slope side plate;

[0021] S4. Pour the counter-slope concrete and remove the formwork.

[0022] Beneficial effects of the present invention:

[0023] (1) The present invention uses customized PVC plastic plates as the side plates of the long sides of the cast-in-place anti-slope, and the short sides use customized clamps as the lateral templates, which have high strength and rigidity, can better ensure the quality of anti-slope molding, and the material can be reused many times and has a high turnover rate;

[0024] (2) The present invention pre-embeds nuts in accordance with the anti-slope positioning diagram before pouring the concrete floor, and fixes them together with the floor formwork. This method can more accurately locate the anti-slope position, and can also reinforce the anti-slope formwork by taking advantage of the pre-embedded bolts;

[0025] (3) The end and corner parts of the new anti-ridge mold of the present invention are customized angle steel clamps, which have the advantages of accurate size, not easy to deform, and easy installation. A card plate is set on the upper side of the angle steel clamp, corresponding to the angle steel clamp at the other end. The card plate is fixed with a retractable full-length steel plate, and a retractable U-shaped card plate is added between the PVC plastic plates. The number of U-shaped card plates can be set according to the actual situation on site. After installation, the U-shaped card plate can be close to the retractable steel plate, and the upper part can clamp the PVC plastic plate, which has both supporting and pulling effects, and is strong and durable and does not deform;

[0026] (4) Since the anti-ridge mold of the present invention is mainly composed of steel plates and plastic plates, the material is durable, and for different anti-ridge lengths, only the template of the long side of the anti-ridge needs to be replaced, and the angle steel clamps at the ends and corners can be used all the time, and the applicability is relatively strong.

[0027] (5) The present invention uses customized water-stop nuts and sleeves to be embedded in advance when pouring floor concrete. The main method of customizing water-stop nuts is to use a small square steel plate to weld nuts on both sides, and then embed them in the corresponding position of the floor template according to the size of the drawing and punch holes. The lower part is fixed with bolts accordingly, and the upper nut is covered with a sleeve to prevent contamination during the pouring of floor concrete. After the concrete pouring is completed, it is only necessary to find the position of the embedded nut and install the angle steel clamp. When installing the angle steel clamp, the length can also be adjusted by using the expansion space reserved by the angle steel, and then the anti-slope template can be fine-tuned and fixed. In this way, the anti-slope template can be accurately positioned and the nuts embedded in the concrete can be used for reinforcement, and the fixing method is stable;

[0028] (6) The bolt pre-embedded method of the present invention is to weld a square steel plate in the middle of the template reinforcement, and the bolts are pre-embedded in the concrete without penetrating the upper and lower positions, so there is no risk of water leakage. After the bolt holes are used, only waterproof mortar needs to be used to fill the bolt holes, which is simple and convenient to operate.

[0029] (7) The template of the present invention is easy to remove. Since only one side of the angle steel clamp is in contact with the concrete, and the other two sides are not in contact with the concrete, the angle steel clamp can be removed first, and then the PVC plastic plates on both sides can be removed. The plastic material is not easily damaged, indicating good flatness and high turnover rate. BRIEF DESCRIPTION OF THE DRAWINGS
