Abstract
The invention discloses a prefabricated panel capable of effectively preventing cracking and a cracking-preventing construction method thereof. The prefabricated panel comprises a panel body (1), wherein a window (2) with an opening in the end face is formed in at least one end of the panel body (1) and is internally provided with tension springs (3) with one end fixedly connected with the panel body (1). The cracking-preventing construction method comprises the steps of splicing the panel, locking the springs and filling and troweling. According to the prefabricated panel, the tension springs are fixedly arranged in the windows in the end faces of the prefabricated panel, and the influence on a joining seam of the prefabricated panel caused by an external force or a climatic factor can be reduced and resisted by using elastic tensile forces and energy storage after the tension springs of two adjacent and same prefabricated panels are locked, thus the prefabricated panel can bear high stress and deformation, and the cracking probability of the joining seam is reduced. The prefabricated panel disclosed by the invention is simple in structure and convenient to install, and brings the convenience to factorized volume production. According to the cracking-preventing construction method, the process is simple, the cracking-preventing effect is remarkable, and the local workload can be effectively reduced.
Description
Technical field
The invention belongs to building material technical field, be specifically related to a kind of simple in structure, easy for installation, the prefabricated panel that can effectively prevent cracking and anti-cracking job practices thereof of being convenient to batch production batch production.
Background technology
China's construction wall is mostly structural clay tile with material at present, and on-the-spot wet method operation, can bring a series of adverse effects such as dead load is excessive, speed of application is slow, work efficiency is low, effective building area minimizing.For this reason, various novel energy-conserving building materials and New Types of Residential Building Structure System have been developed in recent years, prefabricated panel is lightweight owing to having, easy construction, duration are short, the advantage of energy-conserving and environment-protective, adopts with precast hollow slab and makes floor and roof panel is used widely in China residential houses, factory building and public building.
Because the prefabricated panels such as precast hollow slab are that block is installed, in work progress or after being completed, due to factors such as variations in temperature, foundation settlement, construction qualities, can well-regulated full-length cracks often appear along precast floor slab piece direction, generally split up and down logically, this is the common fault occurred in construction work.Although this crack is the safety of entail dangers to engineering structures not, can affect attractive in appearancely, cause unsafe sensation to the user, serious meeting causes plate seam Seepage, affects the use function in house.For crack problem, usually take tiltedly to make a call to one through squeezing into the method for draw point after the inclined hole of seam with Churn drill, although can play a role, this way owing to not having flexiblely to draw, the deformation energy of pressure and compensation, result of use is unsatisfactory.Also take to whitewash after seam crossing nail screen cloth is fixed and broken fluid sealant, this scheme construction is complicated, and only on surface, arranges screen cloth, does not also have balanced deformation energy, is difficult to solve prevent that Material shrinkage from producing the essential problem of cracking.For this reason, develop a kind of simple in structure, constructability, the beautiful and clean precast wall body assembly with anti-cracking function that does not damage again body of wall is the key addressed this problem.
Summary of the invention
The first purpose of the present invention is to provide a kind of simple in structure, easy for installation, prefabricated panel that can effectively prevent cracking of being convenient to the batch production batch production, and the second purpose of the present invention is to provide the prefabricated panel job practices that can effectively prevent cracking that a kind of technique is simple, effect of anti-cracking is obvious, construction volume is few.
The first purpose of the present invention is achieved in that and comprises the wallboard body, and at least one end of described wallboard body is provided with the window of end face opening, is provided with the tension spring that an end is fixedly connected with the wallboard body in described window.
The second purpose of the present invention is achieved in that and comprises wallboard amalgamation, spring locking, the flat step of powder filler, specifically comprises:
A, wallboard amalgamation: by two adjacent can effectively prevent the cracking the prefabricated panel end face overlap and make its window corresponding;
B, spring locking: after the corresponding tension spring of the prefabricated panel after overlapping stretches, mutual locking connects;
C, powder filler are put down: after inserting filler in the window after spring locking and/or end face seam, part is whitewashed and scrapes white.
The present invention arranges the window of sagging and end face opening near the surface of wallboard body end face at prefabricated panel, fix built-in tension spring in window, utilize two adjacent identical prefabricated panel tension springs mutually to stretch and lock after elastic pulling force and energy reserve, or elastic pulling force and the energy reserve of independent prefabricated panel tension spring after fixing with other building unit after stretching, can reduce and resist the impact on the prefabricated panel joint close of external force or climatic factor, thereby make prefabricated panel can bear larger stress and deflection, reduce the cracking probability of seam, have simple in structure, easy for installation, be convenient to the characteristics of batch production batch production.
The present invention adopts the prefabricated panel that can effectively prevent cracking after the end face amalgamation making the window correspondence, tension spring in corresponding window is stretched and locking mutually, then insert filler and whitewash, scrape white in window and/or seam, complete the connection of prefabricated panel.Elastic pulling force and energy reserve due to tension spring in prefabricated panel, can make wallboard after amalgamation reduce and resist external force or climatic factor on the impact of joint close, thereby make prefabricated panel can bear larger stress and deflection, reduce the cracking probability of seam, effect of anti-cracking is obvious; Due to tension spring and be connected and fixed in recessed window, so window can not protrude from wallboard after filling, and is convenient to the later stage to whitewash and scrape white construction, do not affect body of wall attractive in appearance; Wall window and seam crossing whitewash, scrape white after only needing to fill, between prefabricated panel, do not need gluingly, also do not need to lay such as screen cloth, anti-cracking net etc., so construction technology are simple, construction volume is few, the construction period is short.
