Abstract
The invention relates to a one-step forming temporary protection device for a floor reserved hole and a construction method. The protection device comprises that a bottom die is arranged at the bottom of a structural floor reserved hole, side dies are installed on the periphery of the structural floor reserved hole on the bottom die, a cover board is installed at the tops of the side dies and level with the structural floor surface, and the sizes of the cover plate sides are 2 cm to 5 cm larger than the size of the reserved hole. The one-step forming temporary protection device for the floor reserved hole and the construction method have the advantages that the reserved hole sealing and the floor concrete casting are performed simultaneously and formed through one step, a floor hole blocking protection process is performed after the concrete is casted, and accordingly, time and labor are saved. After the reserved hole is blocked temporarily, an L-shaped water proof structure is formed between the cover plate and concrete, so that rainwater and construction water can be effectively prevented from permeating into a next floor, the environmental protection effect is apparent, secondary pollution reconstruction after decoration is prevented, and the reconstruction cost is saved. Besides, the decoration and the mechanical and electrical installation can be performed in advance, so that the construction period is shortened; and the hole protection upper surface is level with the floor surface, so that the material transportation and the personnel moving are facilitated.
Description
Technical field
The invention belongs to building engineering field, particularly a kind of one-time formed floor slab preformed hole mouth temporary protection device and job practices.
Background technology
Existing reserved opening place reinforcing bar disconnects usually, then adopts wooden a tree, used in making timber for boats to do back of the body a tree, used in making timber for boats, and top is laid template the hole is protected.The shortcoming of technique is: could lay the floor protected apron after one, the concrete construction of structure floor is finished, and time-consuming taking a lot of work, and also other constructors have potential safety hazard before laying is finished, and the 2nd, protected apron is higher than floor face, and inconvenient material and personnel carry; The 3rd, when carrying out shutoff, needs bar planting in the reserved opening later stage; The 4th, usually seep water behind the sealing hole, leak, thereby pollute the bottom floor.Technique more and more is not suitable with the trend of green construction.
Summary of the invention
Problem and shortcoming that the present invention exists in order to overcome above-mentioned prior art, a kind of one-time formed floor slab preformed hole mouth temporary protection device and job practices are provided, can guarantee the protection of floor hole and concrete pouring one-step forming, can effectively solve the drawback of pre existing box out mouth guard technology, also be a kind of cutting the waste simultaneously, economize on resources, reduce cost, build a kind of green construction theory.
Technical solution of the present invention is:
A kind of one-time formed floor slab preformed hole mouth temporary protection device, comprise cover plate, side form, bed die, it is characterized in that: bed die is installed in the bottom of structure floor reserved opening, side form is installed respectively around the structure floor reserved opening on bed die, cover plate be installed in the side form top and with structure floor face maintenance level, and the every limit of cover plate size is than the large 2-5cm of reserved opening size.
Described cover plate is wood glue closing lid plate.
Described side form is the comb teeth shape template.
Become " ┛ " type water proof structure between described cover plate and concrete.
Bed die and side form are removed after concrete construction is finished, and described cover plate lower support body is floor hole reserved steel bar.
The job practices of one-time formed floor slab preformed hole mouth provisional protection, it is characterized in that carrying out according to the following steps: for the structure floor reserved opening of the length of side less than 300mm, when the structure floor is constructed, bed die is installed in the bottom of structure floor reserved opening, side form is installed respectively around the structure floor reserved opening on bed die, be processed into cover plate with wood plywood, the every limit of cover plate size is than the large 2-5cm cm of reserved opening size, cover reserved opening, cover plate and structure floor face keep level, concreting is smeared water-repellent paint at cover plate and structure floor seam crossing after concreting is finished.Become " ┛ " type water proof structure between described cover plate and concrete.Bed die and side form are removed after concrete construction is finished.
The job practices of one-time formed floor slab preformed hole mouth provisional protection, it is characterized in that carrying out according to the following steps: for the floor reserved opening of the length of side greater than 300mm, when the structure floor is constructed, bed die is installed in the bottom of structure floor reserved opening, difference mounting broach shape side form around the structure floor reserved opening on bed die, before concreting, it is good with muscle at the bottom of the floor and the colligation of floor gluten respectively with the comb teeth shape side form to press the structure floor working drawing, be processed into cover plate with wood plywood, the every limit of cover plate size is than the large 2-5cm of reserved opening size, cover plate is placed directly in above the floor gluten and covers reserved opening, concreting is smeared water-repellent paint at cover plate and structure floor seam crossing after concreting is finished.Bed die and side form are removed after concrete construction is finished, and described cover plate lower support body is floor hole reserved steel bar.
Good effect of the present invention is: 1. the sealing of reserved opening and floor concrete casting carry out simultaneously, and one-shot forming is carried out the floor sealing hole after having cancelled pouring concrete and finishing and protected this operation, time and labour saving.2. the hole adopts reserved steel bar to replace wooden a tree, used in making timber for boats back up in the traditional handicraft, and not only intensity is higher, and does not need the later stage that the secondary bar planting is carried out at the hole, has saved the expense of bar planting and wooden a tree, used in making timber for boats.3. become " ┛ " type water proof structure between reserved opening cover plate and concrete.After carrying out temporary plugging, can effectively avoid rainwater and construction water to infiltrate the bottom floor, environment protecting is remarkable, and the secondary pollution after having prevented from fitting up is done over again, and has saved rework cost.And can insert in advance decoration and dynamo-electric installation of bottom floor, save the duration.4. hole protection upper surface and floor face are flat, and transport of materials and flow of personnel are convenient.
