Abstract

The invention discloses an arrangement method for eliminating small special-shaped mould boxes of a ribbed floor, which is characterized in that when a plurality of square standard mould boxes are arranged to form ribbed floor plates, the plane size of the ribbed floor plates cannot be matched with the combined size of the square standard mould boxes sometimes, and the matching is achieved by unidirectionally adjusting and increasing the plane size of part or all of the square standard mould boxes without adjusting small special-shaped moulds. The invention has the advantages that: the method solves the problems of the ceiling building being not beautiful and the structure of the ribbed floor being not stressed because of the overlarge size difference of the ribbed floor formed by the small special-shaped moulds, and improves the building quality because the sizes of all the mould boxes are not greatly different and the whole effect is uniform and beautiful.

Description

Mold box arrangement method for eliminating small special-shaped molds of dense-rib floor

Technical Field

The invention relates to a die box arrangement method for eliminating small special-shaped dies of a ribbed floor, belonging to the technical field of building construction.

Background

The dense rib floor consists of thin plates and rib beams with small intervals. The floor system comprises a unidirectional ribbed floor system and a bidirectional ribbed floor system. The dense rib floor has the characteristics of high floor saving, low manufacturing cost, good performance, convenient construction and the like, and is widely applied to large and medium buildings such as residential districts, commercial complexes, office buildings, schools, industrial plants and the like. At present, the dense rib building cover is formed mainly by flat template and the mould box installed on it. In the implementation process, the mould box arrangement is carried out according to the size and the load requirement of each span plate of the floor system and the size of the ribbed mould box and the basic requirement of the application structure design.

In the existing process of arranging the multi-ribbed floor slab mold box, the existing square standard mold boxes are often arranged in the inter-shaft slab block of the multi-ribbed floor slab, and the difference between the combined size of the mold boxes and the inter-shaft size of the slab block is large. It is common practice to consider first the appropriate fine tuning of the beam width dimension and then consider adding one to two smaller profile dies of smaller dimensions than the standard square die, or using a smaller lightweight core die. The starting point for this is that the economic cost is lower because the mould of the small profile mould is smaller than the standard mould. And moreover, the small special-shaped die is small in size and small in using amount, so that the special-shaped die can be machined manually, and the die investment is saved.

In the dense rib floor formed by the conventional method, a standard die in a plate is mixed with a small special-shaped die with a small size, and one of the small special-shaped dies is too large in size difference and does not meet the basic building attractive requirement, so that a ceiling is messy, and the popularization effect of the dense rib floor is seriously influenced. Secondly, because the size of the small special-shaped mould is changed in the plate, the stress is uneven, and the economic index of the structure is influenced. Thirdly, the design layout of the cap and the first rib is also affected when small profile molds are placed on both sides of the panel.

Disclosure of Invention

The invention aims to solve the technical problem of providing a die box arrangement method for eliminating small special-shaped dies of a ribbed floor, so that a method for adjusting the size of a plate block by using the small special-shaped dies is replaced, the arrangement size of the plate block die box is uniform, the structural mechanical characteristics are good, and the problem of the size of a column cap is solved well.

The invention is realized by the following scheme: a method for arranging the mould boxes of small shaped mould for removing the dense rib building roof features that the plates of dense rib building roof are arranged by more square standard mould boxes, and when the plate between axles of dense rib building roof is not matched with the combined size of more square standard mould boxes, the side regulating mould is used to partially or completely replace square standard mould boxes.

The trimming die is an approximately square die box which is manufactured by increasing the size of a square standard die box in a one-way mode and has the length-width side ratio not more than 1.15.

When the plane size of the plate block of the ribbed building roof cannot be matched with the combined size of a plurality of square standard mould boxes, the unmatched combined size is completed without adopting a small special-shaped mould, wherein the small special-shaped mould is a rectangular mould box with the length-width ratio of the mould box being more than 1.15.

When the plane size of the column cap of the building structure is smaller due to the unified size limitation of the square standard mould boxes, the trimming mould is adopted to replace part or all of the square standard mould boxes, and the plane size of the column cap is increased.

The invention has the beneficial effects that:

1. the invention eliminates the dense rib floor with small special-shaped mould combination by slightly adjusting the one-way size of part or all square standard moulds, solves the problems that the ceiling is not beautiful and the quality of the dense rib floor is seriously influenced because of the small special-shaped mould and the overlarge size difference of the mould boxes, and adopts the method to ensure that the sizes of all the mould boxes are not large, the integral effect is uniform and beautiful, the building quality is improved, and the plate mould boxes are uniform in arrangement size and better in structural mechanical characteristics in the aspect of structural design;

2. the invention adopts the method of carrying out one-way small-amplitude adjustment of the plane size on part or all of the square standard mould boxes, increasing the one-way size of the standard mould, subtracting the small mould at the intersection point of the small special-shaped mould and the special-shaped mould, and subtracting the light filling core mould;

3. the invention can reduce a rib beam and a row of mould boxes in one direction or each direction of the plate block by slightly adjusting the unidirectional size of the standard mould and abandoning the harsh use of the standard mould, thereby shortening the construction period and saving the investment of other construction resources;

4. when the size of the column cap is different from the size of the standard mould, a new method for adjusting is added, and when the plane size of the column cap is smaller due to the limitation of the unified size requirement of the mould boxes, the plane size is increased by adopting the one-way adjustment of the part of square standard mould boxes, so that the structural size of the column cap is increased;

5. the invention adopts the method of increasing the plane size of part or all square standard mould boxes in a one-way or two-way mode, adapts to the construction and installation of the ribbed floor, increases the one-way size of the standard mould, thereby reducing or subtracting the construction procedures added by the small special-shaped mould cross mould and the light filling core mould;

6. the invention changes the current mold box arrangement, firstly considers the habit of avoiding excessively increasing the mold investment, although the investment of the mold cost is increased in the production link of the product, the short-term economic effect is not obvious, but the overall quality, the construction period and the comprehensive economy are far more beneficial than the disadvantages.
