Abstract
The invention discloses a construction method for strengthening a perforated plate and a floor slab. The construction method is characterized by comprising the following construction steps: (1) a mortar surface layer of the perforated plate and a mortar surface layer of the floor slab are removed; (2) filler in seams between the perforated plate and a wall body is removed, and the removal range reaches the top surface of a ring beam; (3) a steel linear plate is mounted; (4) a hole is drilled in the wall body, and a steel strand passes through the drilled wall hole and is fixed on the steel linear plate through an anchorage device; (5) the steel strand is fixed on the steel linear plate through the anchorage device after being stretched, and a gap between the steel strand and the wall hole is sealed through high-strength epoxy resin; (6) a seam between the perforated plate and the wall body is filled with expansive concrete; (7) a waterproof layer is constructed; (8) a fine aggregate concrete layer is poured on asphalt felt. The construction method for strengthening the perforated plate and the floor slab is convenient to operate and low in construction cost.
Description
Technical field
The present invention relates to a kind of job practices of reinforcing, particularly a kind of job practices of reinforcing the porous plate floor.
Background technology
Some disease, especially factory buildings that adopt the factory building of porous plate to occur in various degree have vibratory equipment particularly evident, and the disease that the porous plate floor occurs mainly contains following several: (1) porous plate floor occurs with the crack along longitudinal joint between plate; (2) bending phenomenon appears in the porous plate floor; (3) the large tracts of land seepage appears in the porous plate floor.The analysis reason is as follows: because the surface layer of porous plate floor adopts the mortar levelling layer usually, the mortar resistance to tension is very poor, is difficult to prevent the generation in crack.Even some engineering adopts steel mesh reinforcement to strengthen, because steel mesh reinforcement is close to the porous plate floor, mortar and pea gravel concreten are difficult to form whole.In addition, usually fill pea gravel concreten between the porous plate, building of pea gravel concreten is not in place, affects the lateral ties between plate.
Summary of the invention
Technical problem to be solved by this invention provides the disease that a kind of job practices of reinforcing the porous plate floor solves porous plate.
Reinforcement mechanism of the present invention is as follows: back-up coat adopts pea gravel concreten, the transverse prestress system is set up in employing, make the horizontal lower edge of back-up coat be in pressured state, balance transverse bending moment, eliminate the weak link that stress is concentrated, can transmit simultaneously vertical shear and moment of flexure between porous plate, become articulated slab form of structure into rigidly connecting the plated construction form, strengthening the transverse splicing ability of porous plate floor, thereby fundamentally prevent the generation of this series disease; Simultaneously since the transverse splicing of plate rigidly connect from hinged becoming, make the porous plate floor in the carrying situation porous plate and above pea gravel concreten jointly share load, therefore can improve the supporting capacity of porous plate floor.
Construction sequence comprises:
(1) mortar surface layer of removing porous plate floor.
(2) the seam inner stuffing between removing porous plate and the body of wall, the removing scope is to the collar tie beam end face.
(3) steel liner plate is installed, steel liner plate thickness is 8～10mm, and steel liner plate is fixed on body of wall by split bolt.
(4) in the body of wall internal drilling, the aperture is 8mm, and steel strand are fixed on steel liner plate by the porthole that bores by ground tackle, and the diameter of steel strand is 6.5mm, and the steel strand setting space is 0.8～1m.
(5) steel strand tension is used by ground tackle after complete and is fixed on steel liner plate, and the space between steel strand and the porthole adopts high-strength epoxy resin-blocked.
(6) fill expansive concrete in the seam between porous plate and the body of wall, expansive concrete intensity is more than the C35.
(7) construction of waterproof layer leaks in order to prevent floor, lays malthoid on porous plate.
(8) build the pea gravel concreten surface layer on malthoid, pea gravel concreten intensity is more than the C30.
The present invention is easy to operate, and construction cost is low.

(4) in the body of wall internal drilling, the aperture is 8mm, and steel strand are fixed on steel liner plate by the porthole that bores by ground tackle, and the diameter of steel strand is 6.5mm, and the steel strand setting space is 0.8m.
(5) steel strand tension is used by ground tackle after complete and is fixed on steel liner plate, and the space between steel strand and the porthole adopts high-strength epoxy resin-blocked.
(6) fill expansive concrete in the seam between porous plate and the body of wall, expansive concrete intensity is more than the C35.
(7) construction of waterproof layer is laid malthoid on porous plate.
(8) build the pea gravel concreten surface layer on malthoid, pea gravel concreten intensity is more than the C30.
