Description

Technical Field

[0001] The invention belongs to the technical field of ground engineering construction in building construction, and specifically relates to a compartment seam construction method for continuous construction of a large-area floor. Background Art

[0002] With the rapid development of emerging industries such as new energy, medicine, biotechnology, and prefabricated construction in recent years, large-area flooring is widely used in industrial plants, parking buildings, commercial plazas and other construction fields. Large-area flooring has high requirements for crack control and flatness. It is particularly important to take effective technical measures during the construction process to avoid ground cracks, ensure flatness and meet functional requirements.

[0003] In order to solve the problem of temperature shrinkage cracks in large-area floor concrete, traditional processes mainly adopt the method of extending the interval time or "skipping construction". The large-area floor is divided by formwork, and the concrete is poured in each bin. After the concrete has been cured for a period of time, the concrete of the adjacent bins is poured. The use of formwork not only prevents continuous construction, but also easily causes damage to the edges and corners during the demolding process. Before pouring adjacent bins, roughening treatment is required. The chiseled concrete slag is difficult to clean, and there are still construction joints between adjacent bins caused by the first poured concrete and the later poured concrete. There are shortcomings such as affecting the quality of concrete molding, increasing labor costs and a long construction period.

[0004] The application number is "201910738222.6" and the name is "A method for floor construction in a building project". This patent adopts the method of "skip-bin construction" (casting in alternate spans). This method uses wooden planks as templates to divide the strips into sections. It has disadvantages such as damage to corners and the formation of construction joints when the template is removed. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a compartment seam construction method for continuous construction of large-area floors. In this method, adjacent compartments do not need to wait for concrete curing to reach a specified time, thereby ensuring the continuity of the large-area floor concrete structure without demolding, and avoiding cracks caused by temperature changes between the first poured concrete and the later poured concrete.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solution: a method for constructing a large-area floor with compartment seams that can be constructed continuously, the steps are as follows:

[0007] Step 1: Plan the location of the compartment seams according to the size and area of ​​the floor blocks;

[0008] Step 2: Set up a floor thickening layer at the location of the floor compartment joint, and lay the thickening layer reinforcement alternately in the floor thickening layer and the floor area; alternately arrange transverse reinforcement and longitudinal reinforcement on the floor and the floor thickening layer;

[0009] Step 3: After the construction of the floor thickening layer is completed, a pair of channel steels with the same thickness as the floor are used to separate the floor; the channel steels are fixed by steel bar diagonal braces;

[0010] Step 4: Adjust the flatness and straightness of the channel steel to ensure the flatness of the floor concrete and the straightness of the corners;

[0011] Step 5: After the channel steel is set in the compartment joints, the concrete of adjacent compartments can be poured continuously; after pouring, the joints between the compartments are filled with flexible high-strength epoxy resin to reduce the mutual restraint force.

[0012] Furthermore, mortar is used to level the floor and the channel steel.

[0013] Furthermore, the steel bar brace is composed of a brace and two support rods, the two support rods are arranged in parallel, one support rod is vertically arranged on one side of the channel steel, and the other support rod is vertically arranged on the floor thickening layer, and the brace is obliquely fixed between the two support rods.

[0014] Furthermore, the thickened layer reinforcement is a Z-shaped structure, and fixing hooks are provided at both ends of the thickened layer reinforcement.

[0015] Furthermore, fixing hooks are provided at both ends of the transverse ribs.

[0016] On the one hand, the present invention ensures the flatness and straightness of the floor concrete by adjusting the flatness and straightness of the channel steel, and on the other hand, by wrapping the compartment seams with channel steel, damage to the corners at the junction of the floor compartments is avoided, thereby extending the service life of the floor concrete. The present invention can ensure the quality of concrete molding, save costs, and greatly shorten the construction period. BRIEF DESCRIPTION OF THE DRAWINGS
